In time dependent (classical or quantum) particle-based simulators, one needs an algorithm to determine when (and with which properties) electrons are injected from the reservoir into the simulation box. In this work we develop an electron injection model for 2D materials with linear-dispersion materials. The injected model is based on satisfing the required phase-space density of electrons. In particular,...
In this work we present a multiscale simulation of a solid state dye sensitized solar cell including the real morphology of the active layer. In order to include the real morphology the device domain is split into two different regions: one treated using an effective material approximation and another one using the real structure of the blend. The real morphology has been measured using electron tomography...
The move to PWM-based waveforms with substantial high frequency content results in much greater capacitive currents in the stress grading (SG) material and the conductive armor tape (CAT) which increase power dissipation and electric fields within these elements. Treating this subject numerically is challenging for several reasons, viz., (i) the need to measure SG nonlinear properties as a function...
Development of simulation models allows performance analysis of multi-echelon inventory networks, and this part of supply chain is not well-established research area. Moreover, by encapsulating all major characteristics of multi-echelon system, the simulation modeling does not allow only its study, but also it provides the means to achieve the desired system performance. This paper deals with a multi-echelon...
We developed an analytical code to model electromagnetic fields in 3D in a stack of vertical transverse isotropic layers. This code is suitable to model low-frequency as well as high-frequency responses and it is expected to become available as an open source package in 2014. We give an overview of the code and use it to investigate the sensitivity of different Ground Penetrating Radar antenna configurations...
Although information and communication technology (ICT) has been playing an important role in the development of business and society for more than thirty years, its potential benefits and risks for the environment are still not sufficiently explored. This is mainly because of the complex interdependencies between ICT and different other areas of business and society that together build a very complex...
The existing disaster emergency materials management systems are established based on the traditional design mode, the information processing capabilities are limited by the communication control volume of control system, and the asynchronous / synchronous communication and time delay communication are seldom considered. The information sharing and resource integration capability among cities is low...
Simulating the deformation of human tissue during medical procedures that employ needles is important for representing the tissue's elastic behavior, thus providing visual realism to simulated medical training. This article presents a method for simulating the deformation of three-dimensional objects that represent human organs through many tissue layers, in which the following physical parameters...
Computer graphics and virtual reality have emerged as visual/interactive solutions for several applications simulating real situations. Tasks that required large financial resources and time were optimized with such technologies. With the development and improvement of equipment that enable the materialization of digital models, virtual studies can be combined with subsequent physical analysis at...
The study of porous materials involves great importance for a vast number of industrial applications. In order to study some specific characteristics of materials, in-silico simulations can be employed. The particular simulation of pore networks described in this work finds its basis in the Dual Site-Bond Model (DSBM). Under this approach, a porous material is thought to be made of sites (cavities,...
Thermal aware design of integrated circuits is essential to avoid reliability issues and failures especially in 3D-technology where active dies are placed on top of each other and more heat is dissipated on the same area available for cooling compared to conventional 2D-packages. A certain number of parameters can be selected to reduce temperature and temperature gradient. This paper is mainly focusing...
Digital forensic investigation process is about identifying and tracing the cause of the incident, whereby traceability is very important process during the investigation by searching for the evidence. However, the traceability model of digital forensic investigation process is enhanced based on scenario with proven literature and justification.
In this paper we study the possibility to use a transverse flux linear generator (TFG) because transverse flux technology presents the highest force density per volume index among the iron based electrical machines. This paper is organized as follows an introduction to describe “state of the art”of WEC's and TFG, in the Section II we find a summary description of the marine condition of the chosen...
An irregular heartbeat is highly dangerous to an adult, and even more so to an unborn baby. Whether it is poor oxygenation or other more serious conditions, monitoring a fetus's heartbeat is necessary to determine any health issues. While current methodologies are well received from the general public, there is much room for improvement. A potential solution to the drawbacks of common measuring devices...
This paper presents a novel 30 nm n-channel asymmetric Silicon Germanium-on-Insulator (SGOI) based Tunnel Field Effect transistor using Non-Local Band-to-Band tunneling model that shows the good switching characteristic. Here, we analyzed four different models such as Simple Model, Schenk Model, Hurkx Model and Non-Local Model. Germanium is used as the source because of low band gap material and Silicon...
Bird strike, also known as avian ingestion, is the collision between a bird and an aircraft. Bird strikes have always been a cause of worry in the aeronautical industry: Aircraft both old and new have suffered from bird strikes. Jet engine ingestion occurs when the bird hits the jet engine of an aircraft and gets sucked in. Given that the fan blades rotate at a high rpm, bird strike on a fan blade...
Allocation of budget for acquisition of an academic library is an important initiative to enhance the efficiency of management, to accomplish the objectives ensuring the availability of materials in a library. Processing the circulation data of library, two important dimensions, namely, concentration and connection [1] could be explored among departments and library members. This can make the analysis...
In the educational domain Online Learning Environments (OLEs) have become part of many institutions' Information and Communication Technology (ICT) infrastructure. As revealed by previous studies, instructors in combination with their ability to utilize ICT are the key for creating an effective OLE. While previous work mostly focused on the identification of adoption barriers, this study investigates...
Lost sensory or motor functions can be restored using electrical neural prostheses (NP), which include surface NPs, implanted or subcutaneous NPs and the more recent Stimulus Router System (SRS). The latter type of NP outperforms the other types in its selective excitation and least invasiveness. In each case, the achieved performance depends on a multitude of design factors among which the electrical...
Example tracing tutors has proven to be one of the simplest methods for modelling domain limited scenarios within intelligent tutoring systems [1]. The intelligence embedded within this type of tutors lies in the feedback it possesses during creation and how it is triggered based on learner interaction with the example. Since real-life tutoring in 1-to-1 scenarios proves to have the ultimate learning...
