4H-SiC Trench MOSFET with Bottom Oxide Protection

Ensuring gate oxide reliability and low switching loss is required for a trench gate SiC-MOSFET. We developed a trench gate SiC-MOSFET with a p-type region, named Bottom P-Well (BPW), formed at the bottom of the trench gate for bottom oxide protection. We can see an effective reduction in the maximum bottom oxide electric field (Eox) and a significant improvement in dynamic characteristics with a grounded BPW, whose dV/dt is 76 % larger than that with a floating BPW due to reduction in gate-drain capacitance (Cgd). The grounded BPW is found to be an effective means of both suppressing Eox and reducing switching loss.
Modelo de calidad para herramientas FLOSS que dan apoyo al modelado de procesos del negocio

The selection of FLOSS tools supporting business modeling discipline is a complicated task; besides verifying the proper use of language and notations such as BPMN [1], UML [2] and SPEM, we must validate that such tools meet the features of this type of software. Consequently, the quality of these tools should be assessed through a quality model that allows for determining fulfillment of such requirements. This research, currently in progress, included the use and creation of a Quality Systemic Model (MOSCA) [3]. This model is based on ISO 9126 [4], Dromey’s [5] quality model, and the Goal/Question/Metric paradigm [6]. In addition, the instantiation proposed includes software attributes relating to functionality, usability, and maintainability and establishes 75 new metrics, for a total of 128 metrics, to assessing FLOSS tools for Business Modeling purposes. Four tools were selected in order to validate this proposal, namely Eclipse Process Framework Composer (EPFC) [7], StarUML [8], Intalio [9] and y DIA (http://www.gnome.org/projects/dia/), the chosen tool being EPFC, the highest quality tool to support this discipline.
Promotional practices in mission and vision statements of corporate companies: A systemic functional linguistic analysis

Promotional strategies have become discursive practices in corporate companies’ mission and vision statements. However, less focus was given to the role of grammar in shaping this text type as part of promotional discourse. Systemic Functional Linguistics (SFL) is arguably the most definite and certain linguistic analysis as a meaning-making resource. Hence, the purpose of this study was to use transitivity grammar theory in SFL to analyse the use of experiential processes in enacting promotional rhetorical moves. Following purposive sampling, mission and vision statements of hundred international companies, which were ranked by current market capitalization, were selected. Using textual analysis, we applied transitivity grammar theory to manually analyse promotional rhetorical moves. The results were quantified and presented in tabulation form. The findings revealed that mental and relational processes are favoured grammatical patterns used by corporate firms to write mission statements that focus on building public image and establish self-concept. The findings of this research can prove helpful for other corporate companies to use similar grammatical patterns to develop mission and vision statements.
Caring for the Caring Professionals Within a Cancer Hospital: Research into Compassion Fatigue, Burnout, and Distress

ABSTRACT Providing quality care to people approaching the end of their life within the hospital system is important. To date, only limited research has investigated the impact that providing care to people who are dying has on the diverse range of hospital staff who provide the care. As part of a needs assessment to identify the resources and service development required to support all hospital staff, Calvary Mater Newcastle Social Work Department invited hospital staff to complete a questionnaire. A total of 162 respondents agreed to participate. Both clinical and nonclinical staff reported feeling impacted by the death of patients. Participants identified that their current coping strategies and support structures addressed some professional and personal needs, but many were unaware of other available supports and felt that the availability and type of support offered could be broadened to better meet staff needs. IMPLICATIONS All hospital staff (individually and as a group) irrespective of background are affected by caring for those that are dying. Current support structures used by health workers are examined for their efficacy in providing self-care to these workers; other available supports that could better meet these workers’ needs are then explored. Social workers have an essential role to play in creating systems that support and enable health workers to engage in restorative and wellbeing practices.
An automated system for measurement of random telegraph noise in metal-oxide-semiconductor field-effect transistors

A computer-controlled system for measuring the random telegraph noise in small-area MOSFETs is described. The key element is a specially designed current amplifier that employs a feedback technique to separate the fluctuating and DC parts of the drain current. Techniques for automatic extraction of the fluctuation amplitude and time constants from the raw data are also discussed. >
Temperature and velocity profiles along a singular interface between two immiscible fluids

Bedeaux, Albano, and Mazur (BAM) have developed a convenient method to derive the boundary conditions for non‐equilibrium thermodynamic systems made of two bulk phases separated by a free interface. In their description, the interface is considered as a thermodynamic system characterized by its intensive and extensive variables. The boundary conditions describing the free interface are expressed in terms of fluxes, thermodynamic forces, and interface transport coefficients. Previous works have focused on the derivation of the generalized boundary conditions for different systems using the BAM method, but the corresponding solutions and dynamics have not been widely studied. We consider a theoretical two dimensional system made of two incompressible fluids separated by a deformable interface for which the boundary conditions are obtained using the BAM method. Ignoring the effects of external forces, the dynamics of the system is investigated using the method of multiple scales. The hierarchy of equations is solved up to the second order and we obtain conditions that must be fulfilled by the transport coefficients modeling the cross‐effects of the velocity slips and temperature jumps so that non‐trivial asymptotic solutions for the temperature and velocity profiles can be constructed.
Full Scale Models for Person-Environment Interaction

Full scale models are representational systems that can be experienced through touch, movement and operation. For designers and researchers, they are simulated designs to observe, interact, experience and study future systems. An important research tool, full scale models offer an efficient means to examine early design assumptions, evaluate problem definition and develop designed systems. This paper will provide an overview of using full-scale models by product and environmental designers for research, design and development. A bathroom case study that employs full scale models conduct accessibility research and validated design assumptions is presented. The findings of the research indicate that accessible bathrooms do not offer functional benefits to all users, mostly to users with disabilities. And yet, everyone likes accessible features and they want to have them. The results of the research were used to develop a universal bathroom. The paper concludes with recommendations for a new modeling system.
MSU Jumper: A Single-Motor-Actuated Miniature Steerable Jumping Robot

The ability to jump is found widely among small animals such as frogs, grasshoppers, and fleas. They jump to overcome large obstacles relative to their small sizes. Inspired by the animals' jumping capability, a miniature jumping robot-Michigan State University (MSU) Jumper-has been developed. In this paper, the mechanical design, fabrication, and experimentation of the MSU jumper are presented. The robot can achieve the following three performances simultaneously, which distinguish it from the other existing jumping robots. First, it can perform continuous steerable jumping that is based on the self-righting and the steering capabilities. Second, the robot only requires a single actuator to perform all the functions. Third, the robot has a light weight (23.5 g) to reduce the damage that results from the impact of landing. Experimental results show that, with a 75° take-off angle, the robot can jump up to 87 cm in vertical height and 90 cm in horizontal distance. The robot has a wide range of applications such as sensor/communication networks, search and rescue, surveillance, and environmental monitoring.
Real-time simulation of a COGAG naval ship propulsion system

Design and optimization of the propulsion system is a crucial task of the ship design process. The behaviour of the propulsion system, in transient conditions as well as in steady state, is greatly affected by the capability of the control system to manage the available power and to achieve the desired performance in the shortest time. The selection of a proper control scheme is a trade-off between different and conflicting needs. Two of the opposites are: increasing the ship operability by adding more functions and more controls; and reducing the control system development and installation time and cost. In this paper, the rapid prototyping and testing procedure for the development of the propulsion controller of the new Italian aircraft carrier Cavour is presented, using real-time hardware-in-the-loop (RT-HIL) simulation. The procedure is based on a wide use of simulation technology. First, a complete dynamical model of the ship propulsion plant was developed. Then, batch simulation was used to develop the best possible control scheme. Finally, RT-HIL simulation was used to debug the real controller software and to tune the controller parameters before sea trials. The application of the procedure led to a significant reduction in the development phase of the controller design. Furthermore, the adoption of the RT-HIL technology greatly reduced the time spent to tune the control system during the ship delivery phase.
Modeling and experimental verification of common dielectrophoresis on platinum microelectrodes

The motion of neutral matter induced by non-uniform electric fields, i.e. common dielectrophoresis, has become the basic phenomenon of microchips intended for medical, biological and chemical assays, especially when they imply biological and artificial microparticle manipulation. This paper describes the modeling and experimental verification of an interdigitated castellated microelectrode array intended to handle biological objects, based on the dielectrophoretic effects. The proposed design, a whole microsystem including electrical, optical and fluidic interfaces, was developed employing platinum deposited by liftoff, silicon micromachining, and photoresin patterning techniques. The fabricated electrodes have typical dimensions of 50, 70 and 90 μm, and were tested by means of polystyrene microspheres of 4.2 μm in diameter. Positive and negative dielectrophoresis were clearly observed, and the microparticle behavior was coherent with that predicted by the homogeneous particle model as well as with the electric field distributions assessed by the finite element method. The most relevant results are reported here.
Exploiting Two-Level Information Entropy across Social Networks for User Identification

As the popularity of online social networks has grown, more and more users now hold multiple virtual accounts at the same time. Under these circumstances, identifying multiple social accounts belonging to the same user across different social networks is of great importance for many applications, such as user recommendation, personalized services, and information fusion. In this paper, we mainly aggregate user profile information and user behavior information, then measures and analyzes the attributes contained in these two types of information to implement across social networks user identification. Moreover, as different user attributes have different effects on user identification, this paper therefore proposes a two-level information entropy-based weight assignment method (TIW) to weigh each attribute. Finally, we combine the scoring formula with the bidirectional stable marriage matching algorithm to achieve optimal user account matching and thereby obtain the final matching pairs. Experimental results demonstrate that the proposed two-level information entropy method yields excellent performance in terms of precision rate, recall rate, F -measure ( F 1 ), and area under curve (AUC).

A conceptual framework of the relationship between musicking and Personal and Social Well-being for intermediate phase learners in the South African context

This article proposes a conceptual framework to understand the relationship between musicking and Personal and Social Well-being for intermediate phase learners. We analysed the intermediate phase life skills Curriculum and Assessment Policy Statement (CAPS) document to create a priori codes. We employed these codes to analyse literature on musicking and well-being. Through this analysis, it became clear that it is possible to apply musicking as a means to teach Personal and Social Well-being outcomes in the intermediate phase life skills CAPS provided teachers view musicking as cultural and moral education. This article presents a conceptual framework resting on nine propositions that need to be addressed if teachers wish to teach personal and social well-being through musicking.
A Comparative Study of the Fractional-Order System of Burgers Equations

This paper is related to the fractional view analysis of coupled Burgers equations, using innovative analytical techniques. The fractional analysis of the proposed problems has been done in terms of the Caputo-operator sense. In the current methodologies, first, we applied the Elzaki transform to the targeted problem. The Adomian decomposition method and homotopy perturbation method are then implemented to obtain the series form solution. After applying the inverse transform, the desire analytical solution is achieved. The suggested procedures are verified through specific examples of the fractional Burgers couple systems. The current methods are found to be effective methods having a close resemblance with the actual solutions. The proposed techniques have less computational cost and a higher rate of convergence. The proposed techniques are, therefore, beneficial to solve other systems of fractional-order problems.
A sensitive biomimetic enzyme-linked immunoassay method based on Au@Pt@Au composite nanozyme label and molecularly imprinted biomimetic antibody for histamine detection

ABSTRACT In this paper, a sensitive biomimetic enzyme-linked immunoassay (BELISA) method based on an Au@Pt@Au composite nanozyme label was developed for histamine (HA) detection. A molecular imprinted polymer prepared directly on the 96-well plate served as a biomimetic antibody. A BELISA method was developed for HA standard solutions at concentrations ranging from 0.01 to 100.00 mg/L. Under optimal conditions, the novel BELISA method had a low limit of detection (0.069 mg/L) and high sensitivity (7.20 mg/L). The HA spiked in yellow rice wine and liqueur samples were detected by this BELISA method with the recoveries ranging from 84.28% to 108.82%. There was no significant difference of the results between the BELISA method and HPLC for the detection of HA in the red and white grape wine samples.
Numerical Simulation of Two-Dimensional Unsaturated Flow from a Trickle Irrigation Source Using the Finite-Volume Method

AbstractA numerical two-dimensional finite-volume model is developed to predict the moisture-based form of the Richard’s equation that describes the transient flow of water through homogeneous and heterogeneous unsaturated porous media from a trickle irrigation source in a cylindrical flow region. Clay loam soil is selected to represent the homogeneous porous media. This cylindrical flow domain of clay loam soil is initially at uniform volumetric water content. Numerical runs were conducted with a clay loam soil at water application rates from the trickle irrigation source at a small circular pond area. An assessment of the fully implicit and explicit time schemes and arithmetic and geometric mean weighing formulas are evaluated. A good agreement is obtained when comparing the experimental measured positions of the wetting front advance with the predicted results. In general, for numerical modeling of the unsaturated flow equation, the fully implicit time scheme with geometric mean weighing formula for es.
Application of environmental management accounting by small and medium enterprises in South Africa

By focusing on environmental management accounting in SMEs, the study helps SME managers to effectively understand and find better ways of improving environmental management. The paper investigates environmental management accounting applications in manufacturing small and medium enterprises in Gauteng province. Small and medium enterprises were chosen based on their exclusion from the mainstream research on environmental management accounting (EMA). To achieve the main aim of the study, 24 in-depth interviews were undertaken among SMEs’ managers, accountants, chief executive officers, and owners. The study found that physical EMA is more common in SMEs than monetary EMA. 77% of SMEs’ respondents confirm using physical environmental information in their operations. Therefore, SMEs prefer EMA practices with little cost or no cost attached and practices that can effectively generate returns in the short term. In addition, the avoidance of monetary EMA is anchored on the premise of avoiding costly projects with no immediate material financial returns. Therefore, EMA is critical for SMEs to achieve sustainability.
Study of micro-scale limits of solder self-assembly for MEMS

Solder self-assembly of MEMS has been shown to be an excellent approach for assembling three-dimensional MEMS structures by allowing more precise alignments and vastly increased complexity. This paper investigates if solder self-assembly could be applied at the sub-micron scale. Experiments studying the surface energy minimization properties of molten solder demonstrate that surface energy minimized solder spheres as small as 5 nm are possible. However, the intermetallic formation may limit our ability to reach the nano-scales. Nevertheless, even with intermetallic formation, it should be possible to use solder self-assembly at sub micron scale.
The role of reward-based crowdfunding in farm financing: What characterises successful campaign?

The purpose of this paper is to provide insight into the role of reward-based crowdfunding in farm financing, with a focus on its likelihood of success. The study uses a sample of 1,566 projects from the Kickstarter platform between 2014 and 2020. We added the level of urbanisation and relative importance of agriculture in the country's economy to the basic elements to assess the importance of the crowdfunding. We run a logistic regression model to investigate factors that motivate investment decisions. We discovered a statistically significant negative correlation between the self-set campaign goal and project success, as well as a small positive impact of number of backers and a positive impact of the importance of agriculture in the country's economy on crowdfunding success. In an era of rapid innovation and the rise of social networks, this paper contributes to the current literature on the agri-food industry's reword-based crowdfunding approach.
GaN devices for power amplifier design

This paper describes some aspects of the fabrication and modeling of a GaN device to be employed in a power amplifier covering one WiMAX frequency band. The work has been carried out in the frame of the TARGET's NoE work package WiSELPAS. Details concerning the AlGaN/GaN device technology and the performed linear and nonlinear measurements are provided. Since these new devices require specific nonlinear models, a procedure for selecting an appropriate simplified nonlinear model and for extracting its parameters is discussed and evaluated. The developed nonlinear model has been experimentally tested under linear and nonlinear conditions. The agreement between experimental and model-predicted performance suggests that the described model could be useful in a preliminary power amplifier design.
‘Lean first, then automate’: a framework for process improvement in pure service companies. A case study

Born in manufacturing environment, only recently Lean Management has been implemented in services. In particular, the role of automation and information technology in leaning processes is controversial and literature still lacks a strong empirical evidence to clarify how Lean Management can be applied in a pure service context, such as banking services, where there is an intensive use of automation and Information Systems. This study aims to define a methodology to streamline and automate processes in pure service-providing companies. To achieve the research aim, we conducted a case study. Based on the empirical investigation, a framework was developed. We found out that the automation of a process that is not streamlined can generate problems that can slow down the flow and increase errors. A process should first be mapped to highlight waste. Only when the new process is streamlined, it can be automated. In doing so, the new process will automate only value-added activities recognised by the customers. This research contributes to the debate about the possibility to transfer manufacturing methodologies in the service sector.
Analyzing Hot-Mix Asphalt and Portland Cement Concrete Highway Construction Using Probabilistic Optimization for Profit

Contractors constantly have to make decisions about maximizing profits while considering risks associated with choosing construction target levels for various acceptance quality characteristics (AQCs). With more and more states adopting incentive–disincentive pay adjustment provisions for quality as measured by various AQCs, a contractor likely has to evaluate several options before selecting an optimum target quality that will maximize profit at an acceptable level of risk. The greater the number of AQCs, the more complex the assessment that the contractor is required to perform and the less intuition and experience can be relied on. The updated Probabilistic Optimization for Profit (Prob. O. Prof. 2.0) is a computer program used as a probabilistic-based tool designed to assist portland cement concrete and hot-mix asphalt paving contractors in evaluating statistical quality assurance specifications. In addition, it assists the highway agencies in evaluating the appropriateness of their specifications and ensuring that they have no undesirable consequences. This procedure allows the agency to adjust pay factors accordingly while developing specifications. The Prob. O. Prof. 2.0 program is discussed, and examples of its use are provided.
