SURFACE PHYSICS MODELLING AND EVALUATION OF 6H-SILICON CARBIDE METAL-OXIDE-SEMICONDUCTOR FIELD EFFECT TRANSISTORS WITH EXPERIMENTAL CORROBORATION

Title of Dissertation: SURFACE PHYSICS MODELLING AND EVALUATION OF 6H-SILICON CARBIDE METAL-OXIDE-SEMICONDUCTOR FIELD EFFECT TRANSISTORS WITH EXPERIMENTAL CORROBORATION Stephen Kirkman Powell, Doctor of Philosophy, 2003 Dissertation directed by: Professor Neil Goldsman Department of Electrical and Computer Engineering The relatively recent commercial availability of silicon carbide (SiC) wafers has significantly increased the possibility of electronics based on SiC metal-oxidesemiconductor field effect transistor (MOSFET) design. However, current state-ofthe-art SiC MOSFETs possess interface deformities that not only severally degrade SiC MOSFET performance but also complicate the modelling of the surface scattering mechanisms, rendering the conventional modelling techniques insufficient. At the time of this writing, little research towards developing tools that characterize the transport physics of experimentally observed SiC MOSFET behavior has been done. In this work I develop and implement a methodology capable of providing insight into the performance of this promising technology. In order to bridge the gap between theoretical physics and real world experimentation, I have developed a simulation tool capable of solving the drift-diffusion heat flow equations specialized for SiC MOSFETs. The simulator utilizes techniques such as finite difference approximation, linear iteration, and the Smart Newton method. With this simulator I am able to determine and predict details about the surface transport that are not readily accessible using conventional experimental techniques. Using the methodology presented above, I have succeeded in developing a tool that characterizes the physical transport mechanisms indigenous to current state-of-the-art SiC MOSFETs and achieves agreement with experimental data. In short, the gap between theory and experiment has been bridged, and its results provide valuable insight into the roles of various surface scattering mechanisms, including interface trap occupation, surface roughness, and temperature effects.

Comuputation of steady - state series - system availability depends on specific assumptions made about the non failed items during the system failure. In the article is more exact method of calcul global reliability with consideration of various regimes of maintenance.
Introduction to the Team Software Process

Watts Humphrey is the visionary behind the Capability Maturity Model (CMM)(R) and the Personal Software Process (PSP) (sm). The CMM contains a framework for software process improvement at the organizational level. The PSP builds the self-discipline needed for individual programmers to work efficiently and effectively. The author's new Team Software Process (TSP) (sm) details methods to guide the formation of software development teams, to motivate their work, and to enhance their productivity.This book describes an introductory version of TSP, ideal for smaller projects but also useful for learning basic techniques and procedures that apply to other development projects. Methods presented include: how to establish roles; how to conceive, design, and plan a project; how to track and report on progress. The book walks readers through a complete development cycle, illustrating: how best to use the talents at hand; how to formulate well-defined goals; how to coordinate activities for maximum progress; how to promote effective communication; how to alleviate many of the conflicts that undermine teamwork. Team members should not have to expend valuable time and energy reinventing ways to organize and run their team. By following a proven process, the team will more quickly be able to focus on the successful completion of the project itself. To help a team course apply these methods, the book provides two project exercises, with prescribed development goals and team roles.
Learning with FIRST LEGO League

Robotics is a valuable tool for engaging students in the hands-on application of science, technology, engineering, and mathematics (STEM) concepts. Robotics competitions such as FIRST LEGO League (FLL) can increase students’ interest in STEM subjects and can foster their problem solving and teamwork skills. This paper reports on a study investigating students’ perceptions on the influence of participating in a FLL competition on their learning. The students completed questionnaires regarding their perceptions of their learning during the FLL challenge and were also interviewed to gain a deeper understanding of their questionnaire responses. The results show that the students were engaged with the FLL challenge and held positive views regarding their experience. The results also suggest that students involved with the FLL challenge improved their learning about real-world applications, problem solving, engagement, communication, and the application of the technology/engineering cycle.
Diagnostic Technique for Assessing Halitosis Origin Using Oral and Nasal Organoleptic Tests, Including Safety Measures Post Covid-19

Organoleptic tests are essential in the diagnosis and treatment of halitosis due to three main functions: (A) measuring halitosis, for which it is considered as the gold standard method; (B) helping patients to recover their self-confidence as they get more confident each time their breath is well evaluated; (C) assessing the origin of halitosis through oral and nasal organoleptic tests and by comparing mouth and nose exhaled air, which is possible for diagnosing oral, nasal or extraoral origins of halitosis with a very small error margin. Nevertheless, literature for organoleptic scales that recommend the use of nasal organoleptic tests and/or techniques to diagnose halitosis origin is scarce. Two significant aspects that must be contemplated seriously are the potential risk of cross infections following organoleptic tests as well as the lack of safety guidelines, especially with regards to the recent contagious potential of SARS-CoV-2 worldwide. An important safety aspect concerns avoiding performing organoleptic tests whenever feeling flu-like symptoms, such as fever, dry cough, or difficulty breathing. Also, individuals at higher risk for severe illness should not be elected examiners. Although a safer oral and nasal organoleptic technique is being proposed based on literature, organoleptic assessment should be temporarily suspended until the COVID-19 pandemic situation has normalized and further studies to evaluate the safety of different organoleptic tests methods are performed. Depending on the results of the tests a different origin of halitosis can be inferred, thus avoiding diagnostic errors and unnecessary treatments. The regular use of the present technique on patients and in research can provide more precise diagnostic results. It also allows patients to check their breath at home and consequently take some actions to solve or identify the causing issue in case an alteration is detected, as well as reinforces patients` self-confidence when receiving pleasant breath results after consecutive tests.

User's Manual for the RealGasBrine v1.0 Option of TOUGH+ v1.5: A Code for the Simulation of System Behavior in Gas-Bearing Geologic Media

REALGASBRINE v1.0 is a numerical code that for the simulation of the behavior of gas-bearing porous and/fractured geologic media. It is an option of TOUGH+ v1.5 [Moridis, 2014], a successor to the TOUGH2 [Pruess et al., 1999; 2012] family of codes for multi-component, multiphase fluid and heat flow developed at the Lawrence Berkeley National Laboratory. REALGASBRINE v1.0 needs the TOUGH+ v1.5 core code in order to compile and execute. It is written in standard FORTRAN 95/2003, and can be run on any computational platform (workstation, PC, Macintosh) for which such compilers are available. REALGASBRINE v1.0 describes the non-isothermal two(for pure water) or threephase (for brine) flow of an aqueous phase and a real gas mixture in a gas-bearing medium, with a particular focus in ultra-tight (such as tight-sand and shale gas) systems. Up to 12 individual real gases can be tracked, and salt can precipitate as solid halite. The capabilities of the code include coupled flow and thermal effects, real gas behavior, Darcy and non-Darcy flow, several isotherm options of gas sorption onto the grains of the porous media, complex fracture descriptions, gas solubility into water, and geomechanical effects on flow properties. REALGASBRINE v1.0 allows the study of flow and transport of fluids and heat over a wide range of time frames and spatial scales not only in gas reservoirs, but also in any problem involving the flow of gases in geologic media, including the geologic storage of greenhouse gas mixtures, the behavior of geothermal reservoirs with multi-component condensable (H2O and CO2) and noncondensable gas mixtures, the transport of water and released H2 in nuclear waste storage applications, etc.
Optimal Energy Management Strategy for Hybrid Electric Vehicles

This paper presents a preliminary design and analysis of an optimal energy management and control system for a power-split hybrid electric vehicle (HEV) using hybrid dynamical control system theory and design tools. The hybrid dynamical system theory is applied to formulate HEV powertrain dynamical system in which the interactions of discrete and continuous dynamics are involved. The Sequential Quadratic Programming (SQP) method is applied to optimize power distribution. An improved dynamic programming method is employed to determine the optimal power distribution and the vehicle operating mode transitions.
PRODUÇÃO INTEGRADA DE MAÇÃ (PIM) – PROCESSO INOVADOR NA CADEIA PRODUTIVA DA MAÇÃ BRASILEIRA DOI: 10.5773/rai.v9i3.887

With the implementation of Integrated Production of Apple (PIM), the chain of Brazilian apple demonstrated concern with the demands presented by the consumer market and, moreover, confirmed their position as a pioneering segment of innovation in Brazilian agribusiness. Thus, this study aimed to describe the implementation of the PIM, and, through interviews with industry experts who participated in this implementation, examine whether it can be considered an interactive process of innovation. We also consulted files of Brazilian Agricultural Research Corporation (Embrapa) and the Brazilian Association of Apple Producers (ABPM). After analyzing the data, we considered the implementation of the Integrated Production of Apple as an integrative model of innovation, where the centre is a company interacting with another company or the relationship between companies and the system of science and technology. This research found that the implementation of the PIM was an example of innovative process carried out in the production chain of apple.
Mining of Mineral Deposits

Purpose. The study aims at investigating the role of particle size of mineral tailings derived from limestone, limestone marble, dolomite and dolomitic marble in heavy metal adsorption, in both batch and fixed bed conditions, so as to estimate whether grinding and/or sieving is necessary for their utilization. Methods. Fractions of different particle size have been studied. Adsorption has been examined in batch conditions from solutions of 5 mg/l Cd, 5 mg/l Pb, 100 mg/l Cu, 100 mg/l Zn, and their mixed solution simulating electroplating wastewater, and also in fixed bed conditions. Findings. Total Cd and Cu adsorption is achieved on all the mineral fractions, whereas Pb and Zn show a difference up to 20% depending on particle size. Referring to the mixed solution, Cd and Zn adsorption is lower, whereas no significant differences in Cu and Pb adsorption are observed. Adsorption capacity rises up to 0.03 mg/g Cd, 0.60 mg/g Cu, 0.03 mg/g Pb, 0.60 mg/g Zn. In fixed bed conditions, metal adsorption greater than 93% is achieved. Furthermore, leaching not exceeding 4% indicates a good metal retention. Finally, Taguchi method has proven that the particle size effect is not so strong compared to other parameters, including solution concentration and time. Originality. The particle size of mineral tailings has not yet been investigated as a parameter affecting heavy metal adsorption. Furthermore, heavy metal adsorption has been examined from separate metal solutions and not from a mixed one. The present study aims at contributing to these two research fields. Practical implications. Τhe differences in adsorption between mineral tailings’ fractions with different particle size are not as high as to make grinding of minerals necessary.

IT Support for Project Management - affects on integration in a product development process

Issue: To create a supporting IT-tool for project management in an integrated product development process at global companies is a complicated task. The IT-tool must be embedded in the organisation, managing the information flow in a correct way, support the product development framework, be accepted and commonly used in the whole company. These aspects must be fulfilled if an IT-tool for project management should be able to support the integration in a product development process in a global company, for example at Tetra Pak. Purpose: The theoretical purpose is to increase the understanding of how an intranet based support tool for project management affects the integration in a product development process in a global company. The practical purpose is to identify the possibilities and limitations of the Project Management module in Tetra Pak Innovation Network (TPIN) and make suggestions on how this IT-tool can be improved to better support the integrated product development process for international projects in Tetra Pak. Method: Business process has been used as the base element in this thesis. To narrow down this field, theories in integrated product development and information system have been used. By building this concept a focal point could be created. This focal point has then been divided into four essential elements. These elements were then applied to analyse how an intranet based support tool for project management affected integration in the product development process. This analysis was made by using a case company, Tetra Pak, and studying the creation of the IT-tool TPIN and how it has been used in two product development projects: one at Tetra Pak R&D and one at Tetra Pak Carton Ambient. Conclusion: An intranet based support tool for project management does not create integration. Instead this type of IT-tool provides coordination through a common structure and terminology. If the IT-tool is intended to create both integration and coordination it will be stuck in the middle, since these two things requires different levels in detail and adjustment. Coordination requires that there is just one generic version that creates a company-wide structure. Integration on the other hand requires that each project can have their own detailed systems where all daily documents can be handled. It is therefore important to make it clear that the project management module in TPIN is a tool that should provide a company-wide process that facilitates coordination. To create this clearness, daily documents should not be handled within TPIN and different versions of the project management module in TPIN must not be created in different parts of the company.
Nanoporous Carbon Magnetic Hybrid Derived from Waterlock Polymers and Its Application for Hexavalent Chromium Removal from Aqueous Solution

Sodium polyacrylate is the superabsorbent waterlock polymer used in disposable diapers, which are the third largest single consumer item in landfills. As diapers are difficult to recycle, their use produces an incredible amount of environmental waste. In the present article, we present a reliable and facile approach to transform sodium polyacrylate, the main constitute in the used diapers, in a carbon-based magnetic sorbent material, capable for use in environmental applications. A nanoporous carbon magnetic hybrid material was prepared by reacting NaPA with iron acetate species under chemical activation conditions. Analysis of the characterization results revealed, the creation of a nanoporous structure, with high specific surface area value (SgBET = 611 m2/g), along with the formation of nanosized zero valent iron nanoparticles and iron carbide (Fe3C), inside the carbon pore system. 57Fe Mössbauer spectroscopy verified also the existence of these two main iron-bearing phases, as well as additional minor magnetic phases, such as Fe3O4 and γ-Fe2O3. Vibrating sample magnetometry (VSM) measurements of the obtained hybrid confirmed its ferromagnetic/ferrimagnetic behavior. The hybrid material demonstrated a rapid sorption of Cr(VI) ions (adsorption capacity: 90 mg/g, 24 h, pH = 3). The results showed highly pH-dependent sorption efficiency of the hybrids, whereas a pseudo-second-order kinetic model described their kinetics.
Groundwater Recharge Operations in California

Central Valley and the populated coastal regions of San Francisco, Los Angeles, and San Diego. The 1976-1977 drought of the western states focused attention on several water resource management options to meet the water needs of agriculture, industry, and urban areas. These options include measures to reduce water consumption, water exchanges and transfers, conjunctive use of ground and surface waters, and wastewater reclamation and reuse. While the drought highlighted the need for additional water resources development, it is anticipated that the next large increment of fresh water supply will be much higher in cost than existing supplies, due mainly to the remoteness of new water sources, energy and delivery costs, and environmental considerations.
Vulnerability of steel moment‐resisting frames under effects of forward directivity

In near‐fault regions, forward directivity causes long‐period pulse‐like motions with high amplitude and short duration perpendicular to the fault surface. Pulse‐like motions have important roles in forming the distribution of damages over the structure height. Recent studies indicate that the number of spans influences the demand distribution over the moment frame's height. Considering the destruction of the buildings near causative fault in Bam earthquake, Iran (2003) demonstrates that most damages are concentrated in the ground floor of moment frames. Hence, in this study, forward directivity effect on vulnerability distribution of steel moment‐resisting frames with a few number of spans has been studied by nonlinear dynamic analysis of five structural models with different heights under 20 earthquake records. Related to frames height, results showed that 70% to 90% of forward directivity effects are accumulated in lower one‐third or half of model's height. Also, in near field of fault, growing rate of ductility demand at lower parts of model's height is two times higher than that of far‐fault regions. In addition, it was observed that ductility capacity in lower half of low‐rise or one‐third of high‐rise models has a key role in stability of moment frames under near‐fault pulse‐like motions.
