De Bank The Bench
No full textThis book and the accompanying exhibition are the result of a Form Studies exercise held at the Faculty of Architecture at Delft University of Technology (TU Dellt). This practical exercise, entitled 'The Beneh', is part of a second year teaching "Block" (coordinated by Max Risselada) with 'Imaging and Materialisation' as its central theme. The block lasts eight weeks and is part of the basic educational programme at the faculty. It focuses on aspects of industrial (pre)labrication, montage and detailing. The practical study is carried out parallel with the other items of the block, which concentrate on the design of lightweight dwellings and the analysis of design precedents. 'The Bench' was developed and offered by the staff of the Form Studies group, which is part of the Media section. Major themes in the Media programme are Design Visualisation and Presentation. The Form Studies curriculum focuses on aspects of Formal and Spatial Composition. In addition, Form Studies is responsible for the teaching ol three dimensional Modelmaking techniques, which takes place in a well-equipped workshop. In this particular exercise the aspects ol Composition and Modelling come together. As in the previous application, 'The Tabie, as a metaphor lor architecture' , the task that was set was limited and (seemingly) simple: design a bench for the public realm and then 'build' the design in the form of a scale model 1 : 5 or 1 : 10. The students were stimulated to deal with the bench as an architectural object. The ambition of this approach is to confront students with design themes such as function, shape and proportion, but also with qualities and combinations ol materials, logical and expressive detailing and the consequences of 'making'. The idea is that students should continue refining their designs in the realisation phase. For many students, this is an experience approaching that of a first 'realised' project (though of course limited in scope and scale). The exercise, with 'The Bench' as its theme, was offered during 1994 and 1995. The students worked with considerable enthusiasm and the results were varied and, for second-year students, often surprisingly professional. For the Form Studies team this was a reason to organise an exhibition and this publication. We hope you will enjoy the results of the Bench project.ArchitectureArchitectur
Reply to Bench (1973)
No full textThe author is in agreement with Bench 1973 that without specific analysis one cannot be certain that the auditory output from a given loudspeaker matches the input to that speaker. However, issue is taken with Bench concerning the results obtained by Ashton 1971
Designing a landscape bench
No full textThe built landscape that ranges from the paved concrete paths that we walk on to the towering buildings that can rise thousands of feet above. These objects were intentionally designed by people to serve specific functions to benefit us. However, as time moves forward, and we as people change, our designs can become outdated, no longer relevant, or simply not exciting. The landscape bench is one part of the landscape that has struggled to evolve over the years and is limited in the number of functions that it could provide. The landscape bench has been documented for hundreds of years and has served as a place of refuge in the landscape - providing a hub for social interaction, a location to go to, and simply a place to sit. Our current perception and expectations have limited this piece of the landscape to just a place to sit, not allowing for even simple changes to its simple design. Through the design and build process this thesis investigates topics regarding material sustainability, site specific designs, and social interactions in relation to bench design and construction. Through the creation of a prototype and a final model this project created a well researched and designed bench for its site. The process demonstrated that making considerations for history, sustainability and case studies, the landscape bench can be designed and built with meaning and purpose.M.L.A.Includes bibliographical reference

The aim of this paper is to show preliminary results of this investigation where the validation and calibration of the mathematical model is performed determining the hydraulic conductivity of saturated porous media, such as kaolin clay and glass porous filters, with a bench-scale centrifuge
Utilization of a dumbbell floor press in predicting an estimated 1RM max barbell bench bress using repetitions to fatigue
No full textThis research aims to investigate the relationship between the performance of a dumbbell floor press and the traditional barbell bench press, as a safer alternative means of assessing maximal strength in upper body pressing. The 1 repetition maximum (1RM) test using a Barbell Bench Press (BBP) has been widely used for this purpose but can be time-consuming and poses an increased risk of injury when performed incorrectly, particularly among novice individuals. The most common injuries associated with the bench press are anterior glenohumeral instability, atraumatic osteolysis of the distal clavicle, and pectoralis major rupture. Alternative protocols for estimating 1RM, such as the YMCA bench press, sub-maximal BBP, and push-ups, have been established but also pose some risk of injury. The theory is that performing a dumbbell floor press may be a safer alternative, as it provides a stable base for the scapula and shortens the range of motion on the press, eliminating excessive anterior humeral slide. Two case studies have shown that exercises using a bench in horizontal and push-ups can cause bilateral shoulder dislocation. This study aims to fill the gap in the literature by examining the relationship between the dumbbell floor press and the barbell bench press. The findings of this study may provide health professionals with an alternative means of assessing upper body pressing strength for participants who may be at risk of injury with traditional testing protocols.

GSL-Bench: High Fidelity Gas Source Localization Benchmarking
No full textGas Source Localization (GSL) is a challenging field of research within the robotics community. Existing methods vary widely and each has its own strengths and weaknesses. Existing GSL evaluations vary in environment size, wind conditions, and gas simulation fidelity, thereby complicating objective comparison between algorithms. They also lack photo-realistic rendering for the integration of obstacle avoidance. In this paper, we propose GSL-Bench, a benchmarking suite to evaluate the performance of GSL algorithms. GSL-Bench features high-fidelity graphics and gas simulation. Realism is further increased by simulating relevant gas and wind sensors. Scene generation is simplified with the introduction of AutoGDM+, capable of procedural environment generation, CFD and particle-based gas dispersion simulation. To illustrate GSL-Bench's capabilities, three algorithms are compared in six warehouse settings of increasing complexity: E. Coli, dung beetle and a random walker. Our results demonstrate GSL-Bench's ability to provide valuable insights into algorithm performance.https://sites.google.com/view/gslbench/ Website providing additional results and instructionsAerospace Engineerin

No full textKokkuvõtteks võib öelda, et käesolev töö keskendus teststendi väljatöötamisele, mis võimaldaks testida elektriratta akusid vastavalt ettevõtte poolt määratud testidele ja testimise protseduurile. Töös käsitleti testimise protsessi, riistvara komponentide valikut, arvutusi ja ühendusi, samuti testimise läbiviimiseks vajalikke protseduure ja tulemusi.
Teststendi riistvaraline lahendus koosnes mitmest moodulist, sealhulgas juhtimis-, tühjendamis- ja laadimismoodulitest. Iga moodul oli kavandatud ja konstrueeritud vastavalt selle funktsioonile, võimaldades aku testimist vastavalt ettevõtte nõuetele. Samuti lahendus sisaldas juhtseadme, CAN adapteri ja ST-Link prograammeerija valimist.
Testimise protsess koosnes mitmest etapist, alustades aku tuvastamisest ja lõpetades tühjendustestiga. Iga etapi eesmärk oli veenduda, et aku reageerib õigesti erinevatele testolukordadele vastavalt ettevõtte poolt kehtestatud kriteeriumidele.
Diplomitöö tulemusena on välja töötatud teststendi elektriline osa koos valitud komponentide ja nende ühendustega. Edaspidi on vajalik juhtmestiku valik, juhtimismooduli elektroonikaplaadi loomine ning korpuse loomine juhtimismoodulile. Need sammud viivad välja töötatud teststendi realiseerimiseni, mis võib oluliselt parandada ettevõtte aku testimise protsessi.
Kokkuvõttes näitab töö, et välja töötatud teststend on võimeline teostama ettevõtte poolt määratud teste ning tagama aku tõrgeteta toimimise vastavalt elektriratta nõuetele. Lisaks sellele annab töö ülevaate teststendi riistvaralisest ja tarkvaralisest arhitektuurist ning testimise läbiviimise protsessist, mis võimaldab hõlpsasti jälgida ja kontrollida aku käitumist erinevates olukordades.The name of the diploma thesis is Battery Test Bench Development.
The author has completed a diploma internship in a company that deals with the development and production of electric bikes and batteries for them. Battery testing is an important stage in the battery development and production processes. This thesis is based on the topic of developing a test bench for battery testing. The thesis is aimed at solving problems related to battery testing, which exist at the time of writing the thesis. The main problems lie in the fact that battery testing takes a long time, in some cases testing is difficult and the human factor might have a large impact on the performance of tests.
Automation of testing using a test bench would allow optimization of the testing process and solve the existing problems. The aim of the diploma thesis is to develop an automatic test bench hardware solution for testing company batteries. The test bench must be able to carry out the tests specified by the company in automatic mode.
In the first and second chapters, the author described the construction and functionality of the company's battery. In the second chapter, the author analyzed the current battery testing process and its drawbacks and needs. The information and conclusions of the first and second chapters formed the basis for the development of a suitable test bench. The third chapter described the concept and electrical design of the billboard developed by the author of the diploma thesis. Also, the equipment and electronic components needed for the construction of the stand were selected, and a calculation was made to justify the choice of components. In the fourth chapter, the performance of the test bench testing process was described and two sample tests were described to prove that the solution developed is suitable for automation of testing and is able to improve the existing testing process of company batteries.
The result of the diploma thesis is a conceptual solution of the electrical part of the stand with the selected components and their interconnections. Next, it is needed to choose a suitable wiring and create an electronic board for the control module where the selected components can be installed.
