Engineering Science Based on Modelling and Simulation (M & S) is defined as the discipline that provides the scientific and mathematical basis for simulation of engineering systems. These systems range from microelectronic devices to automobiles, aircraft, and even oilfield and city infrastructure. In a word, M & S combines knowledge and techniques in the fields of traditional engineering - electrical, mechanical, civil, chemical, aerospace, nuclear, biomedical and materials science - with the knowledge and techniques of fields such as computer science, mathematics and physics, and social sciences. One of the problems that arise during solar cell operation is that of heating them because of permanent solar radiation. Since the layers of which they are made are very small and thick it is almost impossible to experimentally determine the temperature in each layer. In this sense, the finite element method comes and provides a very good prediction and gives results impossible to obtain by other methods. This article models and then simulates the thermal composition of two types of solar cells, one of them having an additional layer of silicon carbide that aims to lower the temperature in the lower layer, where the electronic components stick to degradable materials under the influence of heat.

Space offers unique experimental conditions and a wide range of opportunities to explore the foundations of modern physics with an accuracy far beyond that of ground-based experiments. Space-based experiments today can uniquely address important questions related to the fundamental laws of Nature. In particular, high-accuracy physics experiments in space can test relativistic gravity and probe the physics beyond the Standard Model; they can perform direct detection of gravitational waves and are naturally suited for investigations in precision cosmology and astroparticle physics. In addition, atomic physics has recently shown substantial progress in the development of optical clocks and atom interferometers. If placed in space, these instruments could turn into powerful high-resolution quantum sensors greatly benefiting fundamental physics. We discuss the current status of space-based research in fundamental physics, its discovery potential, and its importance for modern science. We offer a set of recommendations to be considered by the upcoming National Academy of Sciences' Decadal Survey in Astronomy and Astrophysics. In our opinion, the Decadal Survey should include space-based research in fundamental physics as one of its focus areas. We recommend establishing an Astronomy and Astrophysics Advisory Committee's interagency "Fundamental Physics Task Force" to assess the status of both ground- and space-based efforts in the field, to identify the most important objectives, and to suggest the best ways to organize the work of several federal agencies involved. We also recommend establishing a new NASA-led interagency program in fundamental physics that will consolidate new technologies, prepare key instruments for future space missions, and build a strong scientific and engineering community. Our goal is to expand NASA's science objectives in space by including "laboratory research in fundamental physics" as an element in the agency's ongoing space research efforts.

Dramatic progress has been made in the last several years in our understanding of the properties of neutrinos with evidence for neutrino flavor transformation coming from measurements of atmospheric neutrinos by SuperKamiokande, of solar neutrinos by the Sudbury Neutrino Observatory (SNO), and of reactor neutrinos by KamLAND. These results are a step in the ongoing program of science that is carried out in underground laboratories. The potential for additional significant discoveries with new capabilities in underground laboratories exists and should be exploited. Discoveries are likely to be made not only in nuclear and particle physics, but also in astrophysics, geophysics, and geobiology. A concerted effort is now underway in the United States to create a National Underground Science and Engineering Laboratory (NUSEL) that would provide the facilities and infrastructure necessary to capitalize on the opportunities presented by underground science.

Visualization is a powerful tool for data exploration and analysis. With data ever-increasing in quantity and becoming integrated into our daily lives, having effective visualizations is necessary. But how does one design an effective visualization? To answer this question we need to understand how humans perceive, process, and understand visualizations. Through visualization evaluation studies we can gain deeper insight into the basic perception and cognition theory of visualizations, both through domain-specific case studies as well as generalized laboratory experiments.

A computer vision-based navigation feasibility study consisting of two navigation algorithms is presented to determine whether computer vision can be used to safely navigate a small semi-autonomous inspection satellite in proximity to the International Space Station. Using stereoscopic image-sensors and computer vision, the relative attitude determination and the relative distance determination algorithms estimate the inspection satellite's relative position in relation to its host spacecraft. An algorithm needed to calibrate the stereo camera system is presented, and this calibration method is discussed. These relative navigation algorithms are tested in NASA Johnson Space Center's simulation software, Engineering Dynamic On-board Ubiquitous Graphics (DOUG) Graphics for Exploration (EDGE), using a rendered model of the International Space Station to serve as the host spacecraft. Both vision-based algorithms proved to attain successful results, and the recommended future work is discussed.

Includes bibliographical references (pages 47-49). Physical simulators have been widely used in robot planning and control. Among them, differentiable simulators are particularly favored, as they can be incorporated into gradient-based optimization algorithms that are efficient in solving inverse problems such as optimal control and motion planning. Simulating deformable objects is, however, more challenging compared to rigid body dynamics. The underlying physical laws of deformable objects are more complex, and the resulting systems have orders of magnitude more degrees of freedom and therefore they are significantly more computationally expensive to simulate. Computing gradients with respect to physical design or controller parameters is typically even more computationally challenging. In this paper, we propose a real-time, differentiable hybrid Lagrangian-Eulerian physical simulator for deformable objects, ChainQueen, based on the Moving Least Squares Material Point Method (MLS-MPM). MLS-MPM can simulate deformable objects including contact and can be seamlessly incorporated into inference, control and co-design systems. We demonstrate that our simulator achieves high precision in both forward simulation and backward gradient computation. We have successfully employed it in a diverse set of control tasks for soft robots, including problems with nearly 3, 000 decision variables. by Yuanming Hu. S.M. S.M.

Annotation:
In modern multi-objective design optimisation, an effective geometry engine is becoming an essential tool and its performance has a significant impact on the entire process. Building a parametric geometry requires difficult compromises between the conflicting goals of robustness and flexibility. The work presents a solution for improving the robustness of parametric geometry models by capturing and modelling relative engineering knowledge into a surrogate model, and deploying it automatically for the search of a more robust design alternative while keeping the original design intent. Design engineers are given the opportunity to choose from a list of optimised designs to balance the robustness of the geometry and the original design intent. The prototype system is firstly tested on a 2D intake design repair example and shows the potential to reduce the reliance on human design experts in the conceptual design phase and improve the stability of the optimisation cycle. It also helps speed up the design process by reducing the time and computational power that could be wasted on flawed geometries or frequent human interferences. A case-study of the proposed repair system based on the design and analysis of a three-dimensional parametric turbine blade model has been set up. An automatic analysis workflow is set up and the results are summarised for setting up a repair database based on surrogate training methods. Positive repair results have been achieved and an automatic repair cycle for the blade model is being set up and tested. The proposed physics and engineering knowledge based geometry repair system for robust parametric geometries proves an effective tool for ensuring automation robustness and design flexibility.

Humans often push when grasping or lifting is inconvenient or infeasible, because pushing requires fewer contacts and fights against only a fraction of the object's weight. However, pushing results are hard to predict, because the physical parameters that govern the pushing motion are difficult to measure. We derived a physics-based box pushing model and implemented a feedback-based pushing pipeline using the model. Experimental results show that our pushing model has fair predictive power and our pushing pipeline can reliably push the target to the goal. We compared our physics-based method to a minimalistic baseline pushing method and showed that our method is more accurate and reliable. by Huan Liu. M.Eng.

Thesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2017. Cataloged from PDF version of thesis. Includes bibliographical references (pages 157-159). Sensors embedded within hardware platforms such as smart-watches and cars read in streams of data. These sensor data may be related to each other by invariants or may have other value constraints, but computing in sensor platforms currently ignores these invariants between sensor data. If the programmer wanted to exploit these invariants to perform safety checks or optimize performance, she has to hard-code the invariants in the program. To exploit invariants in software automatically, each compiler of the language used for every sensor platform could be modified to be aware of different sets of invariants in the programs it compiles, or the compilers could take in a configuration file that describes these invariants. This MEng thesis introduces Newton, a language in which the configuration files can be written, as well as a compile-time library and a runtime library that can be used by other compilers to make compile-time transformations to their source code and exploit the invariants in a Newton description at runtime. We introduce two compile-time algorithms that transform intermediate representations of other compilers. The first transformation adds reliability by checking invariants on program variable values at runtime and by running an error handler function if invariants are violated. The second transformation trades off reliability gained from sensor redundancy for performance by removing code that deals with redundant sensors. This thesis describes twelve examples of realistic physical systems that may benefit from using Newton. by Jonathan Lim. M. Eng.

Over the last 50 years, solid state physics and technology have blossomed through the application of modern quantum mechanics to the real world. The intimate relationship between basic research and application has been highlighted ever since the invention of the transistor in 1947, the laser in 1958 and the subsequent spawning of the computer and communications revolution which has so changed our lives. The awarding of the 2000 Nobel Prize in Physics to Alferov, Kroemer and Kilby is another important recognition of the unique interplay between basic science and technology. Such advances and discoveries were made in major industrial research laboratories — Bell Labs, IBM, RCA and others. Today many of these industrial laboratories are in decline due to changes in the regulatory environment and global economic competition. In this talk I will examine some of the frontiers in technology and emerging policy issues. My talk will be colored by my own experiences at Bell Labs and subsequently at a major U.S. national laboratory (Sandia) and at universities (University of California at Santa Barbara and Harvard). I will draw on experiences from my role as the Chair of the National Research Council (NRC) panel on the Future of Condensed Matter and Materials Physics (1999) and as a reviewer of the 2001 NRC report, Physics in a New Era. The growth rates of silicon and optical technologies will ultimately flatten as physical and economic limits are reached. If history is any guide, entirely new technologies will be created. Current research in nanoscience and nanotechnology is already leading to new relationships between fields as diverse as chemistry, biology, applied physics, electrical and mechanical engineering. Materials science is becoming even more interdisciplinary than in the past. Different fields of engineering are coming together. The interfaces between engineering and biology are emerging as another frontier. I will spend some time in exploring the frontier where quantum mechanics intersects the real world and the special role played by designer materials and new imaging tools to explore this emerging frontier. To position ourselves for the future, we therefore must find new ways of breaking disciplinary boundaries in academia. The focus provided by applications and the role of interdisciplinary research centers will be examined. Strangely, the reductionist approach inherent in nanoscience must be connected with the world of complex systems. Integrative approaches to science and technology will become more the norm in fields such as systems biology, soft condensed matter and other complex systems. Just like in nature, can we learn to adapt some of the great successes of industrial research laboratories to a university setting? I will take examples from materials science to delineate the roles of different entities so that a true pluralistic approach for science and technology can be facilitated to create the next revolution in our field.

Cost and availability of fast computer computers have made it affordable to solve complex engineering problems involving multiple physics using a single finite elements model. The practice is commonly referred to as multiphysics modeling. The objective in this study is to investigate the effectiveness of multiphysics modeling tools as applied to engineering design and analysis. Therefore, active noise control, which involves four different fields of sciences and engineering, has been chosen for the study. The physics involved in active noise control are: Electromagnetic, Structural vibration, Fluid, and Acoustic. The initial goal was to solve a simple noise cancellation problem using a single finite elements model and a personal computer. The task was rather difficult and inefficient. The approach presented here uses a single finite element model and combination of two modeling and analysis software. A well known active noise control methodology is used to cancel the noise radiated by a simply supported circular vibrating disk using a loudspeaker. Harmonic load is applied to the disk and the resulting displacements are fed to a controller designed using MATLAB/SIMULINK®. The output of the controller is used in the ANSYS® finite elements model to compute the acoustic field with and without control. The results show that more than one software packages running on separate personal computers are recommended for an effective multiphysics modeling.
