I’ve started digging through the tutorials saved in earlier posts and found the first two not that useful. The Generative Jam Template Belibat uses relies heavily on existing modular synths, and while it gives some helpful process tips in terms of the kinds of modulations one might choose to make to a note, it’s not that relevant to playing bridge samples and modifying them. Then checked out the generative.fm tutorial on web audio, which is far more helpful and leads me to the next phase, although I diverged fairly quickly from his process, because again it’st about modulating the pitch and duration of existing notes.

What I’m trying to do is bend and stretch, shift pitch and duration of an existing audio sample, that can be already a fairly complex sonic landscape, not only a single note.

This systems music is by far the most exciting how-to I’ve found yet + and horrifying though the prospect is, it looks like I am going to have to go back to that mimic future learn course and the other one I signed up for but didn’t get all the way through and knuckle down to learn JavaScript, so I can make sense of these things. Damn!

Learning Web Audio by Recreating The Works of Steve Reich and Brian Eno

by Tero Parviainen (@teropa)

In this guide we’ll explore some of the history of systems music and the possibilities of making musical systems with Web Audio and JavaScript. We’ll pay homage to three seminal systems pieces by examining and attempting to recreate them: “It’s Gonna Rain” by Steve Reich, “Discreet Music” by Brian Eno, and “Ambient 1: Music for Airports“, also by Brian Eno.

After two days in the studio I worked through so many of the conceptual questions that have been bugging me for months. And opened up a stack of new ones.

Basically, I managed to hack my way around the twotone file structure and get my bridge samples into their system, playing as instruments in the data sonification tool.

Brooklyn Bridge plays trumpet Data Sonification TwoTone Example 1

Trumpets now play the Rama VIII Bridge in Bangkok, and the glockenspiel plays the Golden Gate. Problem is, all of these bridge sounds are already so complex, once you start mapping them to different notes in response to the shifts in data, it’s pure sonic chaos! If I had a system that played a sample and shifted the pitch as the data changes, that would be way more seamless. I am enjoying the ad hoc nature of this process though and the way it is forcing me to consider at a much deeper level, the relationship between the data and the sounds.

Golden Gate Bridge Accelerometer Data Sonification TwoTone Bridge Mix Example 2

As imagined, the one to one parameter mapping of sound sample to dataset is not actually that interesting. In terms of compositional complexity – it gets repetitive very quickly. And, extremely dense sonically if I haven’t chosen the initial samples well.

Something one note, simple, not too much going on, without multiple beats or tones.

I have uploaded composition samples, in the process am still navigating how much of this creative experimentation to share and what to keep private for the eventual ‘outcome’. Although as we discussed in the Publishing as Practice workshop today, having ways to show your artistic process can be both liberating and engaging.

Liberating, because it frees you from the grip of perfectionism + as my dear friend Ernest always says: finished is better than perfect! Engaging because while it may pierce the bubble of mystery around your work, it can also make you more approachable. Since this is a project that relies heavily on collaboration, for me it makes sense to make the process as transparent as possible. This allows potential creative partners to dive into the various threads of creative process, and gives a quick overview for anyone interested in working together. It’s also a little alarming, as nothing is ‘finished’ and I don’t feel nearly ready to make it public. Yet here I am, writing for you – whoever you are, dear reader – to lay my artistic soul bare.

There was something else. Ah yes, the constraints of the TwoTone platform mean that I have to take a very ‘zen’ approach to the work. Like the Tibetan Monks I saw in New York City back in 1989, drawing sand mandalas. So intricate and beautiful, painstaking work that they released into the river once it was finished. You can’t stay attached to the outcome if you keep working through the process, over and over again.

Also that there is no ONE definitive work that will come from this. Many variations will emerge. And I am starting to make peace with that as part of the creative process.

I think perhaps I had envisaged – or ensounded? – a massive, global, all the bridges playing together event. But honestly, that is only possible as a conceptual frame. If you take even the 29 sensors on the ONE bridge and try to make a piece out of them, the sonic chaos resulting is going to be almost unbearable to listen to. So I need to find ways to pin it back into a context or reason for listening, and connecting. That is, the bridges have to relate to each other in some way, and to my own practice and experience. Otherwise it becomes totally random. I am starting to find more interesting questions through this process. And dealing with technical issues that I hadn’t even considered – like the sheer volume of data generated by a bridge sensor. And the compatibility or otherwise of the various types of data with each other and the systems I need to use for creating sound compositions.

As an example, I have figured out that the selected storm data from the Hardanger Bridge structural monitoring sensors is only available in mat format but the csv files I need are massive and broken down by hour, throughout the day. So I needed to find out exactly what time did this storm hit? Hurricane Nina seems like a good place to start. Around 2-8pm on a Saturday, 10th January 2015 – now I have attempted to open those csv files but their compression is not playing nice with my computer. It takes another level of engagement now to connect with the engineers and find out if they are interested in the sonification process, and how possible it is to switch formats.

I am charmed to discover that the accelerometers used are made by Canterbury Seismic Instruments, in Christchurch New Zealand, where my mother and grandmother were born. Which makes complete sense, given the magnitude and frequency of earthquakes NZ needs to monitor. Cusp-3 Series Strong Motion Accelerographs.

Technical Specifications PDF – curious, is it possible to convert to audio signal?

I have done this with the B&K accelerometers on the Green Bridge permanent installation in Brisbane, and it only took a simple adapter…

UNDER CONSTRUCTION by Jodi Rose

That brings us up to date, and my decision now to try selecting more subtle bridge samples as a starting point, and find out how they sound using the two datasets I am already working with. Then I need to get my head around the generative composition tools and work on mapping out the structure of the piece for the Church of Our Lady.

Thanks to the generous structural monitoring engineers at NTNU, I have access to an incredible range of accelerometer data from the Hardanger Bridge. It only took one more specific search term, and is published under a creative commons (cc-by) license.

Now the fun really starts – downloading the csv files: LowWind, HighFreq; MaxLift, LowFreq, MaxPitch, HighFreq (which I misread as MaxPatch and thought OMG they have sonified it already! Although perhaps they have. I still need to write and make contact) MaxDrag, LowFreq… The monitoring sensors are in place since 2013, there is seven years of data. And the storms – Storm Nina, Storm Ole, Storm Roar, Storm Thor!

Wind and Acceleration Data from the Hardanger Bridge

By Aksel Fenerci, Knut Andreas Kvåle, Øyvind Wiig Petersen, Anders Rønnquist, Ole Øisethhttps://doi.org/10.21400/5ng8980s Published 18-08-2020 at Norges teknisk-naturvitenskapelige universitet 2764 views

The dataset consists of long-term wind and acceleration data collected from the Hardanger Bridge monitoring system. The data are collected through wind sensors (anemometers) and accelerometers that are installed on the bridge. The dataset includes both the raw data (in “.csv” format) and the organized data (with “.mat” extension based on hdf5 format). Downloadable zipped folders contain monthly data with different frequency resolutions, special events (storms, etc.) and the raw data. Details on the organization of the data can be found in the readme file and the data paper, both of which can be found in the dataset.

Datasets and Weather

Ok I’m breaking this down now – the CSV files are by year and month eg. Raw 2015 1.

Storms happen in January, Storm Nina: 10th Jan 2015, Storm Thor: 29th Jan 2016.

So to focus on the storms, go for the first month. I can’t use their smaller already selected and edited mat files in the data sonification tool. Maybe it’s possible to conver mat to csv? (oh that question that opens up a whole new can of worms!)

And have just discovered that my idea works to replace the audio files in the twotone sampler with my own bridge sounds… except that I have to go through the meticulously and make each NOTE as a bridge sound, as they move up and down on the scale while playing the data. I think that’s enough for today. Back to the sensors.

For now I’m taking the full month raw csv files and parsing them by date. You gotta start somewhere – Storm Nina go!

MELLOM BAKKAR OG BERG
Ivar Aasen

Mellom bakkar og berg ut med havet
heve nordmannen fenge sin heim,
der han sjølv heve tuftene grave
og sett sjølv sine hus oppå dei.

Han såg ut på dei steinute strender;
der var ingen som der hadde bygd.
«Lat oss rydja og byggja oss grender,
og så eiga me rudningen trygt»

Han såg ut på det bårute havet,
der var ruskut å leggja utpå,
men der leikade fisk nedi kavet,
og den leiken, den ville han sjå.

Fram på vinteren stundom han tenkte:
«Gjev eg var i eit varmare land!»
Men når vårsol i bakkane blenkte,
fekk han hug til si heimlege strand.

Og når liane grønkar som hagar,
når det lavar av blomar på strå,
og når netter er ljose som dagar,
kan han ingen stad venare sjå.

Sud om havet han stundom laut skrida:
Der var rikdom på benkjer og bord,
men ikring såg han trelldomen kvida
og så vende han atter mot nord.

Lat no andre om storleiken kivast,
lat deim bragla med rikdom og høgd,
mellom kaksar eg inkje kan trivast,
mellom jamningar helst er eg nøgd.

BETWEEN HILLS AND MOUNTAINS Ivar Aasen

Between hills and mountains out to sea raise the Norwegian get his home, where he himself raise the tufts dig and put their houses on top of them. He looked out on the rocky beaches; there was no one who had built there. “Let us clear and build our villages, and then own the rudder safely » He looked out on the stretcher sea, there was debris to lay on, but there were fish playing down the cave, and that toy, he wanted to see. Until the winter he sometimes thought: “I wish I were in a warmer country!” But when the spring sun on the slopes shone, he got the urge to say home-grown beach. And when liane greens like pastures, when it blooms of flowers on straw, and when nights are as bright as days, he can see no city venare. South of the sea he sometimes loudly slid: There was wealth on benches and tables, but around he saw the bondage quiver and then he turned north again. Let no others about the size kivast, let them brag with wealth and heights, between cookies I can not thrive, between jams preferably I am satisfied.

Wind-induced response of long-span suspension bridges subjected to span-wise non-uniform winds: a case study

Master thesis – NTNU Norwegian University of Science and Technology. Department of Structural Engineering. [E.M. Forbord & H. Hjellvik]

The response has also been predicted using wind data from the Hardanger Bridge, and the predictions have been compared to the measured response. Uniform profiles of wind speed and turbulence have been given different values based on the measured data, more specifically the mean value of all sensors and the value from the midmost wind sensor. It is seen that the choice of value does not affect the accuracy of response predictions. No matter what values are chosen, the predictions are quite inaccurate in general. lntroducing a non-uniform profile of mean wind speed makes the predictions slightly better in some cases, but not noteworthy, and the accuracy is still relatively low. When also including the non-uniformity of turbulence in the response calculations, the predicted response is reduced and the accuracy worsened with respect to the measured response. Accounting for the non-uniformity of self-excited forces shows almost no effect on the predictions. It is concluded that non-uniform wind profiles do not improve the accuracy of predicted bridge response, and that other uncertainties in the calculation methods have larger impact on the predictions than whether the non-uniform profiles are included or not.

2.1 Random Vibration Theory

6.2 Influence of Non-Uniform Turbulence Standard Deviations

In this section, the influence of span-wise non-uniform turbulence standard deviations on the dynamic response will be presented. Three wind speed profiles have been analysed with different turbulence std profiles. The wind speed profiles used are the linear profile and the sinus profile shown in Figure 5.5a and 5.5d, in addition to a uniform wind speed profile. The three different turbulence std profiles shown in Figure 6.15 are studied. They all have the same integrated sum along the span to make them comparable. The two non-uniform turbulence std profiles chosen have the opposite shapes of the wind speed profiles used in this section, because this is often seen in the measurement data from the Hardanger Bridge. Both of these turbulence std profiles will be compared to uniform turbulence standard deviations, for all the three wind speed profiles. The horizontal turbulence std has a span­ wise mean value of 20% of the wind profile’s mean wind speed, and for the vertical component the corresponding value is 10%. The effect of turbulence std on the response is included in the calculations through the wind spectra, which have a quadratic dependancy on the turbulence std, as shown in Eg. (2.40). The span-wise variation of wind speed is also included in the formula. Therefore, to study the effect of the turbulence std profiles isolated, the response using a uniform wind speed profile and different turbulence std profiles has been calculated. In addition comes the linear and sinus wind profiles, to study if the same turbulence std profiles have different effect on these than on the uniform wind speed profile. The calculated response will only be presented for wind profiles with the mean wind speed of 10 mis, because the trends, the shape and differences of the response along the span are nearly the same for all mean wind speeds for the different wind speed profiles.

6.3 Influence of Non-Uniform Self Excited Forces

To study the influence of span-wise non-uniform self-excited forces on the dynamic response, several wind speed profiles have been numerically tested with both uniform and non-uniform self-excited forces. The non-uniform self-excited forces are caused by the non-uniform wind profile. The re­ sponse is predicted with uniform self-excited forces where the aerodynamic properties are dependent on the mean wind speed of the wind profile, and with non-uniform self-excited forces where the aero­ dynamic properties vary along the span with the wind speed. Toen the bridge response in both cases are compared. The wind profiles tested are presented in Figure 5.5. As in section 6.1, the standard de­ viations of turbulence components are span-wise uniform, such that the influence of the non-uniform self-excited forces are investigated separately. The horizontal and vertical turbulence standard devi­ ations have been set to 20 and 10%, respectively, of the horizontal mean wind speed.

The influence of the non-uniform turbulence standard deviation has connection to the shape of the wind speeds along the span. As discussed previously, the response shifts to where the wind speeds is largest. The same can be said about the turbulence std. It was seen that the wind is dominating and shifts the response more than the turbulence std, for this particular shapes and ratio between the mean wind speed and standard deviation of the turbulence components. The horizontal shift in the response due to the non-uniform turbulence std comes from the cross-spectral densities of the turbulence components which is high when two points with large turbulence std are considered.

The effect of including the non-uniform self-excited forces on the response increase with the mean wind speed of the wind profile. The difference between the response using non-uniform and uniform self-excited forces are largest for the highest mean wind speeds studied. The lateral response using non-uniform self-excited forces deviates less from the response using uniform self-excited forces compared to the vertical and torsional response. This is due to the aerodynamic derivatives which has been taken as zero. The reason for the large ratios in the vertical and torsional direction is the aerodynamic derivatives that reduce the total damping and stiffness of the structure as mentioned. For lower mean wind speeds, 10-20m/s, the difference is below 10% for all response components.

Data Sonification toolkit coming together!

Today I’m learning about TwoTone and how to resuscitate a dead web audio interface. The wonderful Øystein Fjeldbo comes by to help me navigate this brave data world, and talks me through some of the options I’m exploring to make a proof-of-concept.

First up, based on a tutorial in the Brexification post from MCT Music Commmunications Technology Master’s student blog at NTNU. This process turns out to be not that adaptable as their sonification works by changing the pitch of a generated tone, and for my purposes I need to pitch shift a sound sample.

However, it’s very handy that it comes embedded in Max for Live (Connection Kit) and I get the sense of how easy it could be to use, once I can add my own sound samples to and swap out their GPS coordinates for the weather at specific bridge locations.

Golden Gate Bridge Accelerometer Data Sonification Example 1 TwoTone

I can change the API to another live data stream, but there is no simple way to swap their synthesised sounds for a sample player. It turns out to be a completely different process, applying parameter changes to a tone generated by the patch, rather than making changes to an audio sample. So, we take a look at the patch made by the students, who have adapted it to their own needs – but again, this is too specific and not quite what I want to do. Now I’m a little concerned that I will have to give the process over to a custom build, but when we look into the code for the mysteriously vanishing TwoTone app, it turns out this is something Øystein can help me rebuild.

What is it for?

TwoTone can be used for understanding data through listening. It makes data more accessible.

Data

TwoTone can be used by itself or in tandem with visualization. Just like in the cinema, sounds add another layer to understanding.

Music

TwoTone is a fun and intuitive way to make your own compositions without any prior musical or technical knowledge.

Google NEWS & DATAVIZED TECHNOLOGIES

Or so the twotone web audio app promises – sadly their domain is no longer active. Even though it was launched with great fanfare on the 5th March in 2019. Only two years on, and it’s already obsolete. “TwoTone is imagined and made by Datavized Technologies with support from Google News Initiative. We hope you like it.” Did Data Sonification fall out of fashion so fast? Luckily it’s open source, and thanks to GitHub, the code still exists. But I have no idea what to do with it, or where to start.

https://twotone.io/ introduction

Where did it go? Technology graveyard from two years ago. Google labs and all.

The talented Øystein, who teaches Data Sonification manages to get this zombie code going… from the graveyard of TwoTone.io https://github.com/datavized/twotone

It’s such a beautiful and simple concept, a data sonification web-based audio tool. You simply upload your dataset and then can choose instrumentation, key, duration, etc. Once we have it running on my browser, I start working my way through the tutorials.

NODEJS

Nodejs – another thing we had to install to get TwoTone working!

https://nodejs.org/en/

https://nodejs.org/en/about/

I really have no idea what any of this means, but I trust that Øystein knows!

Despite not being able to swap out my own sounds with the pre-made samples, it’s satisfying working through the options to make interesting sonification compositions.

Golden Gate Bridge Accelerometer Sonification TwoTone Example 3

I’m pretty happy to be able to add my own csv data sets – a couple of examples from my research. Golden Gate Bridge accelerometers recorded on mobile phone by Stephen Wylie, via kaggle https://www.kaggle.com/mrcity/golden-gate-accel-20180512 This is one minute of data from the “Linear Accelerometer” of the Physics Toolbox Suite v1.8.6 for Android. The data was collected from a Pixel 2 phone on the east side of the Golden Gate Bridge at the midpoint between the two towers of the bridge at approximately 3:20 PM local time on May 12, 2018. CCO Public Domain.

the original data sonification composition sounds like this…

the export is doing a glitchy thing where it only gives a minutes of the sound, not all 30 minutes… I manage to change the key and duration of the notes for variation

But it’s only a problem with this one, not my next attempt using pedestrian data from the Brooklyn Bridge.

I’ve figured out a hack to get my own samples in there – just have to name them exactly as the existing sets are named. Going to work on that tomorrow. Here’s a preview:

There’s a range of durations, from 02 seconds to 14 seconds, and I think the actual notes can be sacrificed for a variety of sounds. This is where it starts to get really creative! And sounds like some wild free jazz. Now I need to do some more study in order to really get a sense of the possibilities of sonification. Here’s the lecture series by Thomas Hermann – one of the people who literally wrote the book on sonification.

Hardanger Bridge monitoring

Next step: contact NTNU engineers and ask for access to their data, pretty please?!

NTNU Case study: The Hardanger Bridge

The Hardanger Bridge is a 1380 meters long suspension bridge, located on the western coast of Norway. It is the longest suspension bridge in Norway, and the 10th longest in the world, which makes it an interesting case study.  Our research in the field of suspension bridges requires knowledge from several engineering fields; such as aerodynamics, signal processing, finite element analysis and control theory. 

Experimental surveys

A comprehensive measurement system is operating on the Hardanger Bridge to improve the current understanding of the dynamic behaviour of long-span suspension bridges and their interaction with wind. This includes sensors for measurement of both response and environmental excitation. The system is described in detail under Structural monitoring (Structural monitoring – The Hardanger Bridge).

The Hardanger Bridge monitoring project

The Hardanger Bridge, opened in 2013, is a 1380 m long suspension bridge crossing the Hardanger fjord in western Norway. The main span is 1310 m long, which makes it the longest suspension bridge in Norway and the 10th longest in the world. The two concrete bridge towers are 200 m high, made using the slip forming technique, and supports the steel bridge casing and the cables that are anchored in the mountain side.

The main objective with the monitoring project is to study the dynamic behaviour of the suspension bridge; especially the wind-induced vibrations. All data generated from the extensive measuring system is directly used in research related to the ferry-free costal highway E39 project; both PhD and master theses. 

The monitoring system consists of the following sensors (illustrated in Figure 2):

  • 20 triaxial accelerometers
  • 9 anemometers

System identification and modal analysis

Based on recordings established by the monitoring system, parameters characterizing the system behaviour; typically represented by natural frequencies, damping ratios, and mode shapes; are estimated (system identification). The results are a highly valuable asset for these applications:

  • Studying the dynamic behaviour of the bridge
  • Updating the numerical model, such that it better describes the real behaviour of the bridge
  • Verification and possible improvement of the current state-of-the-art methods used for numerical modelling
Modal shape of the Hardanger Bridge. Model and animation by NTNU/Øyvind Wiig Petersen.

Load modelling and identification

Modelling of the wind-induced forces on suspension bridges is crucially important for accurate prediction of the dynamic response.

The modelling of the environmental wind loads hinges on the description of the spatial and temporal characteristics of the wind field. The wind data from the field measurements will be used to characterize the wind field. It is aimed to test the performance of load models and reveal the uncertainty involved in response prediction.

The models for motion-induced loads most commonly used in bridge aerodynamics are linear engineering approximations. It has been shown in several case studies that the models are working well when the response of the bridge is dominated by one vibration mode in each direction. Taking into account that the principle of superposition does not hold in fluid dynamics, it is unknown if the models will be able to predict reliable results for a more complex motion. Thus, there is a need to test the accuracy of the linear assumption introduced in the modelling of the self-excited forces. This challenging task does not only require development of new experimental setup but also identification techniques able to work with an arbitrary motion.

MIMIC CREATIVE AI

MIMIC is a web platform for the artistic exploration of musical machine learning and machine listening. We have designed this collaborative platform as an interactive online coding environment, engineered to bring new technologies in AI and signal processing to artists, composers, musicians and performers all over the world.

The MIMIC platform has a built-in audio engine, machine learning and machine listening tools that makes it easy for creative coders to get started using these techniques in their own artistic projects. The platform also includes various examples of how to integrate external machine learning systems for sound, music and art making. These examples can be forked and further developed by the users of the platform.

What does Amper do?

Amper is an AI music company. We develop enterprise products to help people make music using our AI Composer technology. Today we offer two products—our music creation platform Score, and an API that allows companies to integrate our music composition capabilities into their own tools.
What is Score?

Score is a tool for content creators to quickly make music to accompany videos, podcasts, games, and other types of content using our AI Composer. Score is designed to significantly reduce the time it takes to source music and adapt it to fit a particular project.
Who is Score intended for?

Score was built for businesses who create a lot of content and are looking for ways to source high quality music more efficiently. Video editors, podcast producers, and video game designers can all benefit from Score’s capabilities.
How is Score different from stock music sites?

Each track Score outputs is composed by our AI in real-time and is always custom to your project. Collaborating with Score allows you to tailor a broad variety of your track’s musical attributes, including length, structure, genre, mood, instrumentation, and tempo.

Additionally, all the sounds you hear in Score are samples of real instruments recorded at Amper’s Los Angeles studio. Unlike stock music, which is often made using widely available sample “packs”, Score’s sounds are proprietary. This makes Amper’s music truly unique.

Modular Solution for Efficient Structural Health Monitoring

All structures, whether bridges, wind energy plants, water, gas and oil pipelines, tunnels, oil rigs, pavements, rails, but also ships, planes, trains or others are subject to various internal and external factors which may cause wear or malfunction. This can happen, for example due to deterioration, an incorrect construction process, lack of quality control or an extreme situation resulting from an accident or environmental load. To be able to observe these changes in the material and to react in a proper way before serious damage is caused, the implementation of a damage identification system is crucial. The monitoring of structural behavior can detect anomalies in time, thus enabling maintenance and repair actions to be implemented more efficiently, with a direct impact on the reduction of operating costs. Replacing schedule-driven maintenance with condition-based maintenance is the main goal of infrastructure monitoring providing the following benefits.

Gaining Real Insight into a Structure’s Health

Civil engineering structures are withstanding an exponential increase of applied loads, impacts and environmental burdens. The assessment of the resulting structural behavior is becoming mandatory so that faults can be detected in the early stages and safety is guaranteed.

Visual inspections do not give enough information to extend the structure’s lifetime, but by monitoring the structural health, any anomalies can be detected in time. This will optimize maintenance and reduce operating costs.

Monitor your entire structure’s life-cycle – from its design, construction, and operation to its rehabilitation or end-of-service life using HBM turnkey solutions for:

  • Material testing and load assessment
  • Strain and temperature distribution 
  • Convergences and vibration estimation
  • Displacements, deflections, and rotation measurements
  • Continuous monitoring

The new continuing education course at , “Structural Health Monitoring (SHM)”, is very relevant for professionals who design large and complex bridges and buildings, or work with the detection of damage to various building structures. For example, bridges should be monitored at regular intervals to ensure the safety of the users and the environment. The bridges age and are often exposed to higher traffic, train and freight loads than they were originally designed for.

Strategies of structural health monitoring for bridges based on cloud computingMarco Furinghetti1,2 · Alberto Pavese1 · Francesco Lunghi2 · Davide Silvestri2Received: 12 July 2019 / Accepted: 11 September 2019 / Published online: 20 September 2019 © Springer-Verlag GmbH Germany, part of Springer Nature 2019 https://link.springer.com/article/10.1007/s13349-019-00356-5

Strategies of structural health monitoring for bridges based on cloud computinglink.springer.com

The collapse of the Polcevera bridge in Italy represents a serious event which seems to be a direct result of cumulated local damages due to the aggressive environment of the construction site. Recently, evidence of corrosion of both ordinary and post-tension steel reinforcements were detected, in addition to concrete carbonation. Such phenomena generally lead to an increase in the deformation of all the elements of the bridge structure, which start to increase in time, leading to a progressive deterioration of the overall system. As a consequence, a proper structural monitoring layout would provide an extremely useful tool, for a correct plan of maintenance for all the elements of the considered infrastructure. In this work, strategies for the definition of structural health monitoring systems for bridges are discussed, from both software and hardware points of view. More specifically, a Cloud computing interface is considered, to make recorded data available for further analyses and post-processing procedures. The presented definition of the monitoring architecture could lead to the proper maintenance of all the structural elements, preventing the unexpected collapse of the structure.

Context

I got the chance to walk across the Golden Gate Bridge in San Francisco, CA for the first time in 22 years on May 12, 2018. There have been a great many technological advancements since then, as now we are all walking around with powerful computers and sensors in our pockets. I decided it would be fun to measure the bridge and provide others the opportunity to analyze data as to its motion for a brief snippet of time.

Content

This is one minute of data from the “Linear Accelerometer” of the Physics Toolbox Suite v1.8.6 for Android. The data was collected from a Pixel 2 phone on the east side of the Golden Gate Bridge at the midpoint between the two towers of the bridge at approximately 3:20 PM local time on May 12, 2018.

This dataset is hereby owned by the community under the terms of a very lenient license in the condition that I have published it shortly after recording it.

Inspiration

Maybe this will inspire people to install sensors on the bridge, and other bridges, to monitor for things such as traffic (such as to find an optimum speed limit), dangerous fatigue, or dangerous wind conditions. At the very least, one could use this in comparison with a baseline stable motion to see how the bridge shakes. One could study effects of vehicles traversing the bridge (not that there’s any visual data for when that happened relative to this dataset, but I do believe at least one big bus drove by my device during this recording). One could study if there are periodic vibrations, and if so, at what frequencies. This would be even more interesting if correlated with wind data and run compared to several different wind speeds.

Pittsburgh’s Commitment to Transparency – tylertech As with most cities, Pittsburgh is swimming in data. And while having this large quantity of details, databases, and stats can be advantageous, it can also overwhelm, especially if the data isn’t readily accessible.

New York State inspectors assess all of the bridges every two years including a bridge’s individual parts. Bridges are analyzed for their capacity to carry vehicular loads. Inspectors are required to evaluate, assign a condition score, and document the condition of up to 47 structural elements, including rating 25 components of each span of a bridge, in addition to general components common to all bridges. The NYSDOT condition rating scale ranges from 1 to 7, with 7 being in new condition and a rating of 5 or greater considered as good condition. Bridges that cannot safely carry heavy vehicles, such as some tractor trailers, are posted with weight limits. Based upon inspection and load capacity analysis, any bridge deemed unsafe gets closed.

I’m fascinated to receive an invitation from Artsy about helping to share the work of John Cage. Of course, I’d be delighted! It turns out I learned something – I had no idea that Mr Cage, in addition to being one of the most inspirational and experimental musician/composers also made works on paper and in other forms.

“Everything in the world has its own spirit, and this spirit becomes audible by setting it into vibration” said Cage. This concept was a particular inspiration for my 20 year work Singing Bridges, making music with the vibrations of bridge cables. It’s curious to see the plexigram pieces dedicated to Marcel Duchamp, who famously said “The only works of art America has given the world are her plumbing and her bridges.”

There does seem to be a curious synergy between M. Cage, M. Duchamp and the music of bridges.

I’m already a fan of Artsy for their excellent contemporary take on collecting video art and selling art work on instagram, although I have yet to reach these exalted heights in terms of becoming collectable, it’s good to see someone make a living from their work – being a posthumous success as an artist is seriously overrated.

Here’s to vibrations, spirit and new ideas!

“I can’t understand why people are frightened of new ideas. I’m frightened of the old ones.”
-John Cage

Here is the Artsy listing, I’ll be curious to see more of these intriguing works.

“We strive to make all of the world’s art accessible to anyone online. John Cage was not only a revolutionary composer but also an innovative artist, and Artsy aspires to be a leading resource for learning about Cage’s art. Our John Cage page provides visitors with Cage’s bio, over 20 of his artworks, as well as up-to-date Cage exhibition listings. The page even includes related artist & category tags, plus suggested contemporary artists, allowing viewers to continue exploring art beyond our Cage page.”

ABOUT JOHN CAGE

One of the most influential composers of the 20th century and a leading figure in the post-war avant-garde, John Cage was a music theorist, writer, and artist, as well as a composer. His most famous piece,4’33” (1952), consisted of musicians doing nothing but listening to the sounds in a room for the duration of 4 minutes and 33 seconds. For Cartridge Music (1960), he amplified small household objects in a live performance. Influenced by Indian philosophy, Zen Buddhism, and Duchamp’s readymades, Cage championed chance procedures in music, incorporating found sounds, noise, and alternative instruments into his compositions. Two important early collaborators were the painter Robert Rauschenberg and the dancer Merce Cunningham, who was also his romantic partner for most of their lives. Cage published his first book, Silence, in 1961 and, in the 1970s, began to transform literary works, including those of Joyce and Thoreau, into music.

Enquiry on the/our outside

Afterall is pleased to present issue 36, summer 2014, which features artists and artistic collectives that question the borders of the art world or exploit other possibilities within it. Within a homogenizing art world, how do you find a ‘without’ or a productive point of difference?

Clémentine Deliss looks at the collectives Laboratoire AGIT’art and Tenq that emerged in Dakar, Senegal in the 1990s, and which undermined common assumptions about the distribution of cultural capital and knowledge between perceived centers and peripheries. Writing a subjective history of these activities, she asks how groups who wanted to be only partially known can be fully historicized.

K.P. Krishnakumar was the lead artist in the Indian Radical Painters and Sculptors Association, a collective which tried to marry art and politics and look for a way for Indian artists to be part of the global art world without having to represent their national or regional identity. Anita Dube, who was a member of the group, writes on the tragic hero that Krishnakumar became, while Shanay Jhaveri discusses the collective’s impact within Indian art history.

Often showing Turkish women in elaborate camouflage, Nilbar Güreș‘s photographs, drawings, collages and videos also reflect upon questions of cultural identity. Mihnea Mircan argues that she is one of a number of artists who are shifting the notion of identity to one that exists between the margins, blurred in transit, while Lara Fresko considers the artist’s representation of identity within a globalized framework.

Louise O’Hare discusses Andrea Büttner‘s appropriated images of mentally handicapped boys looking at HAP Grieshaber’s woodcuts to elaborate a theory of embarrassment as integral to the condition of viewing art. The social and political uses of art are also examined in Emma Hedditch‘s study of Carla Zaccagnini‘s artist’s book, which explores the Suffragette’s campaign to destroy paintings and art objects.

This notion of an internal hostility to art systems and classic standards of aesthetic criteria is picked up in Alejandra Riera‘s collective projects, for which she renounces any authorship. Her ongoing investigation Enquête sure le/notre dehors (Enquiry on the/our outside), as Peter Pál Pelbart and Muriel Combes write, explores what constitutes the borders of our society—what we relegate, for example, to the peripheries of city centres or outside of sanity.

Already occupying a comfortable position in contemporary art history, Panamarenko defied the parameters within which the art world operates when he decided to retire from artmaking in 2005. As Hans Theys and Jeremy Millar remind us, working mostly in the solitude of his studio in Antwerp, Panamarenko has queried authoritative forms of knowledge through the building of impossible machines.

Finally, in their discussion of the actual experience of living and working in the art world, Zachary Cahill and Philip von Zweck address how artists—whom they dub ‘double agents’—live between structures, seeking to put their day jobs in art institutions at the service of their artistic ‘night job.’

This summer Afterall Books will present the fifth publication in its “Exhibition Histories” series, Exhibition as Social Intervention: ‘Culture in Action’ 1993, as well as the “One Work” title  Thomas Hirschhorn: Deleuze Monument by Anna Dezeuze. On 18 October, Hirschhorn will be in conversation with Dezeuze at the Platform Theatre, Central Saint Martins, to launch the book. The next guest in our “Exhibition Histories” Talks series, co-organised with the Whitechapel Gallery, London, is curator Helmut Draxler, who will be in conversation with Helena Vilalta on 18 September.

Afterall journal is published by Central Saint Martins, London, in editorial partnership with M HKA, Antwerp, and the Smart Museum of Art and DOVA OPC, University of Chicago, in collaboration with UNIA arteypensamiento, Seville, and in association with the University of Chicago Press.

In a practice that poetically blends documentary and fiction, Bertille Bak is developing a unique way of thinking about her contemporaries. As an observer of communities forming and breaking up within delimited territories, she works less like an entomologist pinning down species than with the dreamlike recreation of rituals considered as bearing witness to forms of collective living.

Whether it concerns her own community in the mining areas of Northern France or groups that are unfamiliar to her, she never chooses to distance herself or look on from afar. On the contrary, it is all about sharing a passage of life, a struggle, a resistance. For Bertille Bak, the projects are therefore set in a period of time, several months in general, during which she immerses herself in a reality and in everyday life, establishing herself there and making connections with groups who often live in precarious circumstances close to disintegration.

This is how she came to be interested in the inhabitants of an area of Bangkok under threat from a shopping development, staging the implosion of one of the apartment blocks at the end of a revolutionary swan song in Morse code light flashes. Or again in the Roma encampment of Ivry-sur-Seine in the Parisian suburbs, their forced silence and the inevitable dissimulation that awaits them.

Together with members of the communities, she elaborates a scenario in which people who are ordinarily constrained to passive resistance, and a sort of invisibility, become the actors of their own stories within their usual environments: the everyday replayed, amplified and redirected blending with the fiction imagined by the artist.

In Saint-Nazaire, where she has been a resident artist at Le Grand Café over the last two years, Bertille Bak has also formulated a locally anchored project that seeks to reveal sometimes hidden realities. She is interested in the shipyards, by the mechanical ballet of the machines, and she wishes to accentuate the people who work on the construction of the most sumptuous cruise ships and the crew on board these sea-going giants.

Their community is no longer bound by a common history and is first of all defined through work and the sharing of limited time and space, in which everyone has to find their place.

For this exhibition, the artist has produced a film in which the cruise liner, the recreation of a territorially delimited microcosm in the middle of international waters, is chosen as one of the background elements. With its set of spaces reserved for tourists and forbidden to employees, the cruise ship universe engenders a kind of regimented choreography, where zones reserved for some are forbidden to others.

Elegantly titled The Tour of Babel in reference to these partly invisible communities of different nationalities and individualities, this presentation will very certainly mix objects that evoke the rituals of seamen and women, as well as their voyages and their occasionally absurd comings and goings.
