This paper intends to study the phenomena of thermal-caused material modifications in the principle of nanoscale electro spark during the SPM-based electric lithography. Since the direct observation of the electro spark process seems impossible in the nanoscale gap region, the molecular dynamics (MD) simulation method is applied to help investigate the influence of the thermal effect due to the Joule...
nanoHUB.org is arguably the largest online nanotechnology user facility in the world. From an initial user base of about 1,000 users, nanoHUB has grown to support over 250,000 users annually. nanoHUB supports users in 172 countries with materials for research and education, along with a wide variety of simulation tools covering many nano-related areas. Preliminary assessments of user behavior patterns...
In this paper a novel, highly interactive virtual environment for molecular design using gesture recognition is presented. The system is novel in its concept as it enables the user to directly manipulate molecular structures on the screen, in 3D space, allowing the exploration and visualisation of molecular interactions at different relative conformations. By a series of gestures, the user can pick...
Working memory capacity (WMC) is a cognitive trait that affects students' learning behaviors while performing complex cognitive tasks. Knowing students' WMC can positively enhance students' learning in many ways, for example, by providing them with adaptive content and activities to suit their individual WMC. This paper presents an approach for identifying students' WMC from their learning behaviors...
The effectiveness of model-driven engineering relies on our ability to build high quality models. This task is intrinsically difficult. We need to produce sufficiently complete, adequate, consistent, and well-structured models from incomplete, imprecise, and sparse material originating from multiple, often conflicting sources. The systems we need to consider generally comprises software components,...
Aiming at the effect of different length-to-diameter ratio of charge in EFP shaping, the process of a kind of hemispherical EFP shaping is modeled and simulated with ANSYS/LS-DYNA simulation software. The process of EFP shaping and parameters of the processing are studied. The different data of length-to-diameter ratio of charge are obtained by changing the height of charge, and then the process of...
Agents are autonomous, social, proactive, reactive, and communicate to achieve common goal. Developing framework for agents to support above mentioned characteristics is quite challenging. Outside the choice of right agent methodologies to support agent oriented development, there is a need for developing agent driven development framework to enable creation and functioning of agents. These framework...
Accurate simulations of SAW elements require accurate material parameters. However, literature values, usually based on measurements of thick crystals, mostly don't reflect the properties of thin film layers used within SAW devices with the necessary precision. In this work, a parameter identification procedure is presented, which can determine these material parameters based on measurements of admittance...
First, it is introduced that the BIM technology in the paper in order to solve the problem of built drawings and the completion of settlement in the completion phase. Then, verifying the feasibility of BIM technology in the completion phase through judging whether that matches two conditions. The first condition is whether the completion model with BIM is integrity or not. The second is the BIM technology...
This work describes preliminary steps towards nano-scale reservoir computing using quantum dots. Our research has focused on the development of an accumulator-based sensing system that reacts to changes in the environment, as well as the development of a software simulation. The investigated systems generate nonlinear responses to inputs that make them suitable for a physical implementation of a neural...
We currently notice a substantial growth in the wind energy sector worldwide. This growth is expected to be even faster in the coming years. This means that a massive number of wind turbine blades will be produced in the forthcoming years. There is a large potential for materials savings in these blades. The analysis of designed blade is done in dynamic loading. Five types of spars cross-section are...
The dual-primal finite element tearing and interconnecting (FETI-DP) method is combined with the Newton-Raphson method to expand the capability and improve the efficiency of three-dimensional finite element analysis (FEA) of nonlinear electromechanical and electric machine problems. Despite its modeling capability and high degree of accuracy, FEA has high computational complexity, especially for nonlinear...
Bayesian approach is nowadays commonly used for inverse problems. Simple prior laws (Gaussian, Generalized Gaussian, Gauss-Markov and more general Markovian priors) are common in modeling and in their use in Bayesian inference methods. But, we need still more appropriate prior models which can account for non station-narities in signals and for the presence of the contours and homogeneous regions...
Lithium ion (Li-ion) batteries are the standard choice for many applications; but their behavior is complex. In order to safely and efficiently exploit their advantages, advanced model-based Battery Management Systems (BMS) are required. This paper introduces a computationally efficient, control-oriented model for a Li-ion cell. The model, by augmenting the classical Randle model with diffusive dynamics,...

The first part introduces the developed approach to molecular modeling, which allows the study of the properties of thermal interface materials which provide...
This paper represents, selection of material for biogas storage cylinder using different methods. The best material is then selected from it. Biogas contains some traces of hydrogen sulphide, which is corrosive in nature. During cylinder design more focus has been given on points like low weight, low cost and material for storage cylinder. This paper presents a practical application of some classes...
The Molding process of injection-molded plastics induces certain characteristics in the material that are not accurately modeled in the conventional FEM methodologies for Mechanical stress analysis and Modal analysis. This paper brings out the challenges that are encountered in the current simulation methodologies and discusses few of the methods practiced in the industry to overcome these challenges...
With recent advancement in Radio Frequency Identification (RFID), RFID-based track-and-trace anti-counterfeiting has attracted considerable research interests. A track-and-trace anti-counterfeiting system requires an integral and reliable electronic pedigree (e-pedigree) to ensure high product visibility along the supply chain. With the continuous movements of large volumes of products along the supply...
In this study, an analytical procedure to synthesize a biphasic composite panel with spherical inclusions is developed. The procedure is based on the knowledge of a frequency dependent Debye parameters associated to a homogeneous material with desired shielding performance. The proposed procedure is validated by applying the analytical expression to different biphasic composite structures with different...
