The development of firearms has been included as an introduction and use at the University of Defense. However, using firearms that are not used freely is a barrier for students to understand the ins and outs of firearms better. Therefore, in this research, firearms are replaced with interface simulation design. One firearm that needs to be designed for interface simulation is the G2 Combat pistol. The reason for using the G2 Combat pistol in making an interface simulation design is because the Indonesian armed forces have widely used it. The interface simulation design uses Pimp My Gun software. The method of designing the G2 Combat pistol interface simulation uses the waterfall method. The waterfall method is considered easy and systematic. After the interface simulation design is carried out, the results are compared with the original item or image, photo, and others. Assessment of the G2 Combat pistol interface simulation design with the original pistol by comparing and finding the level of similarity. The assessment results are 87.61% at imgonline.com and 86.14% at blue2digital.com. With two assessment results close to 100%, the G2 Combat pistol interface simulation design is successful. However, there still needs to be improvements so that the interface simulation design is even better in the future.

4H-SiC based semicircular electrode metal-semiconductor-metal (SEMSM), triangular electrode MSM (TEMSM) and conventional electrode MSM (CEMSM) ultraviolet (UV) sensors have been modeled, investigated and characterized with numerical simulator ISE-DESSIS. By comparing with relevant experimental data, the model correctness is verified. The electrical and optical features of these sensors are simulated and calculated to character the effect of the novel electrode on performance enhancement. In contrast to CEMSM device, the SEMSM and TEMSM sensors show an outstanding superiority in terms of higher photocurrent, comparable low dark current and excellent quantum efficiency. At a bias of 30 V, the dark currents of SEMSM and TEMSM sensors are below 3.5 pA and the photocurrents are 20.7 nA and 23.7 nA under 310 nm UV illumination, respectively. Furthermore, the peak responsivity is estimated to be larger than 0.135 A/W, 0.156 A/W at 290 nm and maximum quantum efficiency at 280 nm is 58.8% and 67.7% for semicircular and triangular electrode structure, respectively.

This study compares 2 controllers, the On-Off controller and the PID-Simulated Annealing which is a PID control whose parameters are tuned using the simulated annealing method. Both methods are applied to the incubator accompanied by 3 disturbances in the form of variations in the outside air temperature which affect the temperature inside the incubator. The performance of the two controllers is calculated using the Integral Time Absolute Error (ITAE) criteria. The results showed that the average ITAE between On-Off and PID-Simulated Annealing controls was 534,925 and 1,894. These results it can be concluded that the PID-Simulated Annealing control is the most effective control in regulating the temperature of the air inside the incubator and can maintain the air temperature from interference due to outside air temperatures.

Plus que le sport, l’haltérophilie et la force athlétique sont largement utilisées dans la préparation physique pour la performance sportive. Comme ils consistent tous deux à soulever des charges importantes, ils doivent être bien exécutés pour éviter les blessures et améliorer la forme physique et les performances. A ce jour, les conseils de coachs expérimentés ou diplômés ou autoproclamés pullulent dans les salles de sport et sur le web, mais très peu s'appuient sur des connaissances scientifiques. Les mêmes instructions techniques sont souvent données à des hommes et des femmes ayant des caractéristiques anthropométriques et des formations différentes. Comme elles ne sont pas individualisées, ces instructions pourraient être au mieux non optimales pour la plupart des athlètes, ne leur permettant pas d'exprimer tout leur potentiel et, au pire, dangereuses et provoquant des blessures. L'objectif central de notre projet est le développement et la validation d'un modèle humain virtuel personnalisé optimisé. D’une part, un modèle mécanique virtuel d’un athlète effectuant un squat a été conçu numériquement et mis en mouvement par le développement d’un algorithme génétique minimisant une fonction de coût. D’autre part, une expérience a été conçue pour mesurer la cinématique du squat d’athlètes expérimentés. Les résultats de la simulation et de l'expérimentation ont ensuite été confrontés, les différences expliquées et les axes d'amélioration répertoriésMore than sports, weightlifting and powerlifting are widely used in fitness/resistance training for sport performance. As they both consist of lifting additional weights they must be well executed to avoid injuries and enhance fitness and performance. To date, pieces of advice from experienced or graduated or self - proclaimed coaches, swarm in gyms and on the web, but very little are based on scientific knowledge. The same technical instructions are often given to men and women with different anthropometry and training history. As they are not individualized, these instructions could be at best suboptimal for most athletes, not enabling them to express their full potential and, at worst, dangerous and causing injuries. The central objective of our project is the development and validation of an optimised personalized virtual human model. On the one hand, a virtual mechanical model of an athlete squatting was numerically designed and set into motion by the development of a genetic algorithm minimizing a cost function. On the other hand, an experiment was designed to measure the squat kinematics of experienced athletes. The results of the simulation and experimentation were then confronted, the differences explained and areas of improvement listed

"Hot tearing study of aluminium alloys above the solidus temperature with the aid of a direct chill casting surface simulator (DCSS) = : Étude sur la fissuration à chaud d'alliages d'aluminium au-dessus du solidus à l'aide d'un simulateur de surface de la coulée semi-continue."

La déchirure à chaud est un défaut important observé lors de la coulée de certains alliages d'aluminium. Elle se produit au cours de la solidification lorsqu’une petite quantité de phase liquide reste emprisonnée dans la phase solide, affaiblissant la résistance en tension et conduisant à la fissuration de l’alliage. Dans le cas de la coulée semi-continue d’alliages d'aluminium (coulée avec refroidissement intensif et continue), la fissuration à chaud s’initie à la surface des lingots de laminage, là où la microstructure est particulièrement vulnérable, c’est-à-dire juste après la zone du refroidissement primaire. Afin d'étudier le comportement thermomécanique de ces alliages lors de la fissuration à chaud et l'impact de l’utilisation d’affineurs de grains, des essais de traction ont été effectués à de faibles taux de déformation sur des échantillons solidifiés dans un état semi-solide (fraction solide ~90-95% vol.) avec l'aide d'un appareil appelé DCSS (Direct Chill Surface Simulator). Cet appareil est constitué d’un banc d’essai reproduisant les conditions existantes pendant le refroidissement primaire du procédé de coulée semi-continue d’alliages d’aluminium.
Le comportement thermomécanique des échantillons partiellement solidifiés sous l’application de charges en tension a été analysé et la formation de fissures à chaud a été observée. La température à différents endroits dans les échantillons, la charge appliquée et la déformation en surface ont été mesurées lors d’essais de traction effectués sur les alliages d'aluminium AA5182, AA6111 et AA3104. La microstructure de chaque spécimen a été examinée et analysée à l'aide d’un microscope optique afin d’évaluer l’aspect colonnaire ou équiaxe des grains et de son effet sur le comportement thermomécanique de l'alliage. Une importance particulière a été portée sur l'évaluation de la fraction solide présente dans chaque échantillon coulé au début des essais de traction, tenant compte de la température locale, du gradient thermique et des taux de refroidissement appliqués.
Il a été observé que des concentrations excessives d’affineur de grains diminuaient la résistance mécanique en tension des coquilles solidifiées en raison d’une porosité plus élevée induite par une nucléation plus facile des nouvelles phases (gaz inclus). On a aussi constaté que les taux de refroidissement de l’alliage augmentaient avec la quantité d’affineur de grains, relié à un phénomène associé au nombre plus élevé des points de contact avec la surface du moule causés par les nombreux petits grains équiaxes. Finalement, la conception d’un critère basé sur la contrainte thermomécanique pour expliquer la fissuration à chaud a été renforcée par l’observation d’une meilleure résistance mécanique en tension obtenue sur des coquilles avec des microstructures non affinées pour les alliages AA5182 et AA6111 ayant des fractions solides similaires, mais avec des tailles de grain significativement différentes.Hot tearing is a severe defect in aluminum castings which is produced during solidification when a certain amount of liquid phase remains and weakens the tensile resistance of the alloy. In direct chill casting of aluminum alloys, hot tears initiate at the surface of sheet ingots just after the primary cooling zone, where the microstructure is particularly vulnerable. In order to study the thermomechanical properties of these alloys and the effect of grain refiners on their thermo-mechanical behaviour, tensile tests were carried out on specimens in the semi-solid state (~90-95% solid fraction) and at low strain rates using an apparatus called Direct Chill Surface Simulator (DCSS). This apparatus is an instrumented rig test reproducing the conditions prevailing during the primary cooling stage of the DC casting process. The thermomechanical behavior of solidifying shells and the hot tear formation under applied tensile loads was analyzed and the occurrence of hot tearing was observed. The temperature in different locations of the casting, applied load and surface strain were monitored during the tensile tests conducted on aluminum alloys AA5182, AA6111 and AA3104. The microstructure of the tested specimens was examined using the optical microscope to evaluate the columnar or equiaxed aspect of grains and their effect on the thermomechanical response of the alloy. A special emphasis has been given to the evaluation of the solid fraction existing in the castings at the start of the tensile tests, taking into account the local temperature, thermal gradient and cooling rates experienced. It was found that excessive grain refiner additions decreased the strength of solidifying shells because of the increased level of porosity induced by easier nucleation of new phases (gas included). It was also observed that cooling rates increased with the level of grain refiner, a phenomenon that was associated to the higher number of contact points with the mould obtained with numerous small equiaxed grains. Finally, the concept of a stress based criterion for hot tearing was reinforced by the strengths obtained on not grain refined AA5182 and AA6111 alloys showing similar solid fraction near the surface, but with significantly different grain sizes.

La sicurezza degli spazi architettonici in emergenza implica una corretta gestione del processo di evacuazione. L’attuale approccio alla progettazione è influenzato da determinismo e schematicità: si suppone che conformazione di spazi e facilities (sistemi di wayfinding) sia di per sè in grado di plasmare il comportamento umano. Il progettista spesso adotta metodi semplificati (da manuali e norme) che considerano l’evacuazione un evento fluidodinamico con scelte umane rigidamente codificate. La letteratura dimostra però come i rapporti uomo-ambiente rendano vane le soluzioni comunemente adottate. Inoltre, stessi problemi sono riscontrati a grande (spazi urbani) e piccola scale (singoli edifici).
Lo studio propone un nuovo approccio: il behavioural design (BD) intende progettare spazio e facilities basandosi sul reale comportamento umano. Le fasi principali sono perciò comprensione del comportamento umano con prove sperimentali, sviluppo e validazione di simulatori di evacuazione; analisi del processo per individuarne le criticità; proposta di soluzioni e valutazione dell’impatto tramite simulatore o prove reali.
La metodologia BD è applicata a 2 casi riguardanti scenari esistenti complessi. Cardine è minimizzare gli interventi grazie alla localizzazione dei punti critici del processo e alla progettazione di nuovi componenti edilizi.
Il primo caso ha visto lo sviluppo di un modello per la simulazione dell’evacuazione post-sisma su scala urbana. Il modello può essere usato per stimare il rischio includendo il fattore umano, valutare l’efficacia di interventi su edifici ed asseto urbano, e di procedure di emergenza.
Il secondo caso sviluppa nuovi sistemi di wayfinding in edifici storici (teatri). Essi sono progettati per interagire efficacemente con le persone, guidandole attraverso le corrette vie di fuga, e senza apportare sostanziali modifiche al layout architettonico. Il lavoro è stato svolto anche in coordinazione con il cluster TAV-progetto SHELL O.R.4.4.Occupants' safety in architectural spaces during an emergency is essentially connected to the evacuation process. Current strategies are influenced by a schematic and deterministic approach: it is supposed that building layout and wayfinding systems can directly induce individuals’ behaviors. Interventions on buildings could be enough for reducing people risk, because occupants would surely behave in “the correct way” (e.g.: using right paths). This approach seems to exclude behavioral aspects: experiments demonstrate enormous differences between theoretical and real behaviors in evacuation. Same problems are noticed at both small (building) and wide (urban) scale. Hence, this study focuses on a behavioral point of view and defines a “behavioral design” (BD) approach for increasing people’s safety in architectural spaces. BD is aimed at adapting architectural spaces depending on human behaviors! Hence, method phases include: understanding behaviors in emergency through experiments/real world events; defining and validating evacuation simulation model; analyzing emergency processes through simulator; proposing design solutions based on retrieved critical behaviors and verifying their impact by simulator or drills. The BD method effectiveness is shown by 2 cases. Firstly, an earthquake pedestrians’ evacuation simulator is developed. The model is able to represent man-environment interferences in damaged scenarios and can be used for evaluating vulnerability-reduction interventions on buildings, urban planning and rescuers’ management strategies. The second case concerns wayfinding systems definition in building heritage (theater). Systems are defined so as to address correct evacuation path choices, by reducing overall risks with no architectural modifications. This issue is considerably significant in these buildings because of preservation principles and minimum intervention criterion. This work was developed in accordance with “TAV-progetto SHELL-O.R.4.4” activities.

Este trabalho visa dar continuidade à implementação do sistema StatSim (Statecharts Simulator), em linguagem orientada a objetos e com utilização de padrões de software em linguagem Java e banco de dados relacional Sybase. Dessa forma os modelos recuperados na engenharia reversa e o projeto realizado na reengenharia parcial, já efetuada, serão utilizados. A continuidade do processo de reengenharia do ambiente StatSim ocorrerá com a inclusão de uma interface gráfica para apoiar os recursos de edição e simulação de Statecharts existentes na versão anterior. Alguns padrões propostos por Gamma e Grand e o padrão de projeto Model-View-Controller serão estudados e integrados ao ambiente na medida do possível. Um experimento será conduzido para verificar a manutenibilidade das versões existentes desse ambiente.

<p>In 2015-2016 Destia Ltd conducted a study to examine the stress variations caused by actual traffic on two-lane road bridges. Actual traffic was studied using a purposely developed simulation software. Destia Ltd collected data of the traffic flow from automatic monitoring stations. An article based on the research was presented at the 19th IABSE Congress Stockholm, 21-23 September 2016 [1].<p> This study expands the previous analysis to include the determination of equivalent stresses that are used to estimate the fatigue damage of structural steel and reinforcing steel bars caused by actual traffic flow and to evaluate the remaining lifetime of the three existing bridges. Two of the bridges were composite bridges and one a reinforced concrete bridge. In addition to the simulated traffic the bridges were also loaded with eurocode’s static load model LM1 and fatigue load models FLM1 and FLM3. At the end, the results were compared to the simulated results.<p> This article focuses on the results of one of the examined bridges, Liisanniemi bridge, which is a composite bridge with 58m + 78m + 58 m spans and 8,5m width. The main results of fatigue analysis of reinforcing steel bars are also shortly presented at the end of the article.

A qualidade de software é uma das principais preocupações desde as fases iniciais de desenvolvimento do software. Para isso, o software deve evoluir constantemente para atender as necessidades dos usuários e do ambiente (lei da mudança contínua). Por isso, são realizadas manutenções no software. Mas, se as manutenções forem conduzidas em discordância aos padrões de projeto empregados e às melhores práticas de programação, o software se tornará progressivamente mais acoplado e menos coeso, degradando sua qualidade, pois se torna menos modularizado. Assim, neste artigo, é proposta uma abordagem para reestruturar sistemas de software baseada na movimentação de classes entre pacotes para aprimorar a modularização e a manutenibilidade desses sistemas, melhorando sua qualidade estrutural. A movimentação de classes é determinada por uma heurística de otimização combinatória (Simulated Annealing). O resultado da avaliação indica que essa abordagem aprimora simultaneamente o acoplamento e a coesão do software, movimentando baixo percentual de classes, sem afetar estrutura de pacotes do software.

Este trabalho compara modelos matemáticos utilizados para representação de uma linha de transmissão real, trifásica e transposta do sistema elétrico de potência brasileiro analisada no domínio da frequência considerando distorções harmônicas de tensão e corrente. Para tanto, é utilizado o modelo $\pi$ equivalente em componentes de fase, com correção hiperbólica, que garante a exatidão dos parâmetros da linha mesmo com a variação da frequência. Além desse modelo, são utilizados dois métodos desacoplados os quais representam modelos simplificados de transformação modal valendo-se da teoria de componentes simétricas de Fourtesque e de Clarke. Neste artigo, o desenvolvimento de cada modelagem é explicitado e resultados de simulação são validados através do uso do RTDS (Real Time Digital Simulator) assumindo injeções de correntes harmônicas e a análise da linha no domínio da frequência.

O despacho ótimo de Geração Distribuída (GD), em sistemas de distribuição de energia elétrica consiste em se determinar o montante de potência a ser injetada de forma a se obter benefícios operacionais. Redução das perdas ativas, aprimoramento do perfil de tensão e redução da emissão de poluentes são alguns destes potenciais benefícios. Neste trabalho, realiza-se uma comparação entre o Particle Swarm Optimization (PSO) e o método do gradiente descendente para a otimização do despacho de GD. O objetivo principal aqui considerado é a minimização das perdas ativas, mantando-se a tensão dentro de limites regulatórios. Todas as simulações são realizadas com duas GDs conectadas ao sistema IEEE 13 barras. O cálculo do fluxo de potência trifásico desequilibrado é feito pelo software OpenDSS, (Open Distribution System Simulator). Os resultados obtidos mostram que ambas as ferramentas são eficazes na resolução do problema proposto, com o PSO encontrando menores perdas e o gradiente convergindo mais rapidamente.

Carbon-based composites have become indispensable materials in aerospace and other high-performance applications, yet obtaining a detailed, nanoscale understanding of their morphology and failure mechanisms using only experimental methods remains a difficult challenge. REACTER is a versatile computational modeling tool for atomistic molecular dynamics simulations designed to model chemical reactions at the speed and length scales of classical force fields. In this work, several recent features of REACTER were applied to the creation and subsequent mechanical testing of two classes of carbon composites: carbon nanotube (CNT) composites and carbon fiber reinforced polymers (CFRP). A network of CNTs was grown dynamically using the new ‘create atoms’ feature of REACTER. The CNT filler was embedded into a polyarylacetylene (PAA) matrix by simulated in situ polymerization to obtain the final composite model. To generate the second class of carbon composite, fully carbonized (graphitic) carbon fiber morphologies were created by the method of Desai et al. [1], but using the advanced reaction constraints framework of REACTER. Two fiber models were created, representing a circular carbon fiber core and a flat surface, and similarly infiltrated with resin to obtain the final CFRP structure. Failure mechanisms were elucidated by simulating mechanically induced bond breaking, as characterized by third order DFT-based tight-binding simulations, via a reaction constraint on the total potential energy of the involved atoms.

In the early morning on the 4th of August 2014, a tailings dam near Quesnel, BC burst, spilling approximately 25 million m3 of runoff containing heavy metal elements into nearby Quesnel Lake (Byrne et al. 2018). The runoff slurry, which included lead, arsenic, selenium, and vanadium spilled through Hazeltine Creek, scouring its banks and picking up till and forest cover on the way, and ultimately ended up in Quesnel Lake, whose water level rose by 1.5 m as a result. While the introduction of heavy metals into Quesnel Lake was of environmental concern, the additional till and forest cover scoured from the banks of Hazeltine Creek added to the lake has also been of concern to salmon spawning grounds. Immediate repercussions of the spill involved the damage of sensitive environments along the banks and on the lake bed, the closing of the seasonal salmon fishery in the lake, and a change in the microbial composition of the lake bed (Hatam et al. 2019). In addition, there appears to be a seasonal resuspension of the tailings sediment due to thermal cycling of the water and surface winds (Hamilton et al. 2020). While the water quality of Quesnel Lake continues to be monitored for the tailings sediments, primarily by members at the Quesnel River Research Centre, the sample-and-test methods of water quality testing used, while highly accurate, are expensive to undertake, and not spatially exhaustive. The use of remote sensing techniques, though not as accurate as lab testing, allows for the relatively fast creation of expansive water quality maps using sensors mounted on boats, planes, and satellites (Ritchie et al. 2003). The most common method for the remote sensing of surface water quality is through the use of a physics-based semianalytical model which simulates light passing through a water column with a given set of Inherent Optical Properties (IOPs), developed by Lee et al. (1998) and commonly referred to as a Radiative Transfer Model (RTM). The RTM forward-models a wide range of water-leaving spectral signatures based on IOPs determined by a mix of water constituents, including natural materials and pollutants. Remote sensing imagery is then used to invert the model by finding the modelled water spectrum which most closely resembles that seen in the imagery (Brando et al 2009). This project set out to develop an RTM water quality model to monitor the water quality in Quesnel Lake, allowing for the entire surface of the lake to be mapped at once, in an effort to easily determine the timing and extent of resuspension events, as well as potentially investigate greening events reported by locals. The project intended to use a combination of multispectral imagery (Landsat-8 and Sentinel-2), as well as hyperspectral imagery (DESIS), combined with field calibration/validation of the resulting models. The project began in the Autumn before the COVID pandemic, with plans to undertake a comprehensive fieldwork campaign to gather model calibration data in the summer of 2020. Since a province-wide travel shutdown and social distancing procedures made it difficult to carry out water quality surveying in a small boat, an insufficient amount of fieldwork was conducted to suit the needs of the project. Thus, the project has been put on hold, and the primary researcher has moved to a different project. This document stands as a report on all of the work conducted up to April 2021, intended largely as an instructional document for researchers who may wish to continue the work once fieldwork may freely and safely resume. This research was undertaken at the University of Ottawa, with supporting funding provided by the Earth Observations for Cumulative Effects (EO4CE) Program Work Package 10b: Site Monitoring and Remediation, Canada Centre for Remote Sensing, through the Natural Resources Canada Research Affiliate Program (RAP).
