In this study\, thes e effects will be studiedexperimentally. In particular\, we will examine t he turbulent flow interactionswith heterogeneous agriculture fields and th eir effect on the momentum\, heat\,and humidity fluxes\, governing the can opy ET rate. To simulate these effects\, acorn canopy model\, based on lea f area index (LAI) will be constructed in a windtunnel to represent agricu lture fields. The model will allow measurements ofthe turbulent boundary l ayer (BL) characteristics and identification of thesecondary flow properti es. Our main measurement tool will be a combination ofstereo-PIV and hot-w ire anemometry. Additional experiments with direct waterevaporation measur ements are planned\, using temperature\, heat flux and humiditysensors. \n Link to Zoom invitation:https://technion.zoom.us/j/98856741682 END:VEVENT BEGIN:VEVENT UID:6@cee.technion.ac.il DTSTART;TZID=Asia/Jerusalem:20210302T143000 DTEND;TZID=Asia/Jerusalem:20210302T153000 DTSTAMP:20210228T124420Z URL:https://cee.technion.ac.il/seminars/shai-schneider-deep-learning-model s-for-depth-extraction-of-landscape-scenes-from-a-single-or-a-limited-set- of-images/ SUMMARY:Deep learning models for depth extraction of landscape scenes from a single or a limited set of images [No Categories] DESCRIPTION:Location: Civil and Environmental Engineering Speaker: Shai Sc hneider\n \n The talk will be given in Hebrew\n Abstract\n\nImage based depth extraction has been a long-studiedproblem. Classical methods rely on the geometry of two or more views observingthe same scene. Depth extracti on from a single view has also been studied\,where geometric constraints t hat required prior geometrical knowledge\, e.g.\,parallelism or known obje ct dimensions were employed. Nonetheless\, when naturalscenes are involved \, depth extraction from a single view becomes a challenge.\n\n \;\n\n To facilitate depth extraction from a single view\,this research proposes a novel neural networks based approach suited fornatural environments. To do so\, we explore the effectiveness of common lossfunctions\, and design a network suited for the problem. We also demonstrate thebi-modal nature o f the depth values in the landscape scenario\, and howutilization of this aspect improves the estimation of depth. We demonstrate ourmodel on standa rd datasets and on a new one we generated. Results showimprovement on exis ting state of the art results and predictive capabilities forup to 2500 me ters. \n Link to Zoom invitation:https://technion.zoom.us/j/98198000292 END:VEVENT BEGIN:VEVENT UID:10@cee.technion.ac.il DTSTART;TZID=Asia/Jerusalem:20210505T123000 DTEND;TZID=Asia/Jerusalem:20210505T133000 DTSTAMP:20210412T062020Z URL:https://cee.technion.ac.il/seminars/a-robust-approach-to-model-shared- automated-vehicles-users-acceptance-using-stated-preference-and-serious-ga mes/ SUMMARY:A robust approach to model shared automated vehicles users’ accep tance using stated preference and serious games [No Categories] DESCRIPTION:Location: Civil and Environmental Engineering Speaker: Shelly Ben Zvi Etzioni\n \n The talk will be given in \n Abstract\n\nThis study proposes a novel methodological framework to model shared automated vehicl esacceptance and user preferences using multi-methodology that involves st atedpreferencesurvey with an emergingmethodology\, used for the first time in this context\, serious games.

Em. Per-Olof Gutman\nThe rapid development of civilian UASs poses the p roblem of flightsafety. Therefore\, there is an essential demand for devel oping methods for UASsthat would be based on previous aviation experience and will be practical onthe one hand\, and on the other hand\, meet the fu ll-scale civil aviationstandards. Some such methods have been developed fo r model identification\,flight simulation\, and flight control design prop oses. However\, gaps arerequiring further research. For instance\, in-flig ht encounters with turbulenceare significant obstacles to successful fligh t. Consequently\, the primaryobjective of this research is to develop in-f light algorithms for turbulenceestimation for aircraft not equipped with d irect turbulence measurementsensors. Therefore\, it is proposed to use sta ndard UAV sensor kit and controlsignals produced by the flight control sys tem as primary data for turbulencecomponents reconstruction. This estimate should be represented in theappropriate aviation turbulence intensity met ric and can be online downlinkingto the ground station. It can also be sav ed on the storage device withcorresponding UAV's position for further turb ulence mapping.  The development of such algorithms should bebased on act ual flight data for the selected experimental helicopter\, and itshould al so be extendable to any small-scale rotary-wing UA. The traditionalfixed-w ing approach of turbulence modeling is not always applicable torotary-wing aircraft due to different flight regimes and aerodynamic conditions.Furth ermore\, the existing turbulence models for full-scale rotorcraft arecompr ehensive\, computationally expensive\, and therefore of no practical use f orUAV programs. Therefore\, the related objective is to derive from flight testdata turbulence and ship-airwakes models\, which can be used for flig htsimulation\, hardware-in-the-loop tests\, and stability and performance analysisof small-scale RUAV control systems. Full-scale rotorcraft disturb ancerejection requirements focus solely on steady-state response and not t akingtransient behavior into account. However\, there are still no quantit ativedisturbance rejection requirements for the shipboard environment. The refore\, inthis research\, new disturbance rejection specifications could be derived fromcontrol system performance analysis as successful flight co ntrol designcriteria under strongly turbulent conditions\, such as landing on a ship deck. \n Link to Zoom invitation: END:VEVENT BEGIN:VEVENT UID:12@cee.technion.ac.il DTSTART;TZID=Asia/Jerusalem:20210727T143000 DTEND;TZID=Asia/Jerusalem:20210727T153000 DTSTAMP:20210714T094211Z URL:https://cee.technion.ac.il/seminars/land-policy-and-urbanization-multi -dimensional-multi-purpose-land-management-systems/ SUMMARY:Land Policy and Urbanization: Multi-Dimensional Multi-purpose Land Management Systems [No Categories] DESCRIPTION:Location: https://technion.zoom.us/j/97059348994 Speaker: Ruba Jaljolie\n \n The talk will be given in \n Land Policy and Urbanization : Multi-Dimensional Multi-purpose Land Management Systems\n\nAbstract\nHig h density of urban construction and high demand of land\, especially in in dustrial and commercial centers\, lead to overlap and integration of compl ex urban structures in space.

Thus\, it has a strong influenceon the biology and geochemistry of the benthic ecosystem and the overlyingwater. Resuspension results from physical stresses impos ed by currents andwaves that form a nepheloid layer\, and from the benthic activity of organisms (hereafter“biological resuspension”) such as fi sh that borrow for food\, which typically generatesdistinct particle puffs . While physical resuspension is dominant in highcurrents and wavy coastal regions\, biological resuspension is the dominant mechanismin low-energy environments. While low-energy environments are predominant inthe deep sea they are also common in closed basins. Despite its importance\, lessthan a handful of estimates of the average fluxes that stem from biologicalresu spension are available. The main reason is the lack of methodologies thatc an quantify biological resuspension. In my research\, I have developed afo otprint model that estimates the vertical resuspension flux from measureme ntsof the horizontal advective flux. The footprint model is based on the i ntegralmass conservation law and considers advection and settling of the s edimentparticles. A rigorous derivation of the model was followed by a the oretical sensitivityanalysis that was performed to identify which environm ental parameters influencethe model accuracy. It was found that the grain size distribution\, the medianheight of the particles within the puff\, an d the puffs’ median height arecrucial to accurately estimate the resuspe nsion flux. To test the footprintmodel performance\, a Lagrangian stochast ic simulation program was developed.The program generates random puffs\, f ollows the particles locations as they areadvected and settle\, and measur es their concentration at simulated detectors. Usingthe simulated concentr ations\, the resuspension flux calculated by the footprintmodel was compar ed to the flux generated by the simulation. While the resultsshow high acc uracy for all the tested parameters\, we found that the model’sprecision is influenced by the number of puffs in each measurement\, thevariance of the vertical distribution of mass within the puff at the moment of resusp ension\,and by the variance of the puffs’ height. While the footprint mo del did not explicitlyaccount for the effect of turbulent dispersion\, I f ound that for the commonturbulence intensity value of 10% the results were still accurate (mean error<\;15%) for particles with settling velocity greater than 1.9 cm/sec. Thus\, itis concluded that the footprint model is highly accurate in areas of coarse sedimentor negligible turbulent disper sion.\n\n \; \n Link to Zoom invitation:https://technion.zoom.us/j/867 5790728 END:VEVENT BEGIN:VEVENT UID:13@cee.technion.ac.il DTSTART;TZID=Asia/Jerusalem:20210901T130000 DTEND;TZID=Asia/Jerusalem:20210901T133000 DTSTAMP:20210809T074927Z URL:https://cee.technion.ac.il/seminars/september-seminar/ SUMMARY:September seminar [No Categories] DESCRIPTION:Location: https://technion.zoom.us/j/98198000292 Speaker: Ran Soffer\n \n The talk will be given in \n Abstract\n\nHigh density of urb an construction and high demand of land\, especially in industrial and com mercial centers\, lead to overlap and integration of complex urban structu res in space.

Structural systems comprising RC frames with masonry infill walls are w idely implemented in residential and public buildings. The masonry infill wall is usually considered as a non-structural element. Yet\, even if not meant to\, it plays a major role in the structural response in the case of an extreme event such as local impact\, blast or earthquake and shear fai lures of the frame commonly observed. The results of large-scale laborator y tests on RC infilled frames subjected to vertical displacement field and a unique testing facility that allows measuring the infill-frame interact ion will be presented. In addition\, the presentation will be discussing a multi-scale modelling technique for the modelling of RC infilled frames a nd particularly brittle shear failures of the RC frame. A detailed non-lin ear response of the RC elements using the Modified Compression Field Theor y (MCFT) will be presented and its applications for the response of infill ed frames under earthquake action and sudden column removal. The implement ation of the model in Hybrid-Multi-Platform simulations to improve computa tional efficiency will be shown. The presentation will include discussion of a detailed investigation into the structural safety of a large segmenta l PC West Seattle Bridge (WSB) and a sectional-based analysis methodology for the evaluation of the shear strength of disturbed regions.\nAbout the speaker\nAlex Brodsky is a Lyon Sachs Postdoctoral Fellowship at the Unive rsity of Toronto\, Canada.
