Social Networks are evolving rapidly to have a significant number of users using or joining their platforms daily, and a huge volume of information exchange and flow continuously. As human is the center of all information traffic, the information propagation became subjected to the relations and influences between the sources of these information and their followers or fans, these influences might...
Discriminating exo-atmosphere micro-motion targets is a key technology for precise guidance systems, infrared surveillance systems, and satellite remote sensing systems. Commonly, static IR images are insufficient to discriminate different targets in the field of view. The infrared signature, i.e., the time sequence of the target point's gray level in the infrared images serve as potential discriminants...
Machinery industry has constantly driven research on automation systems that use mechanical energy to increase the efficiency, productivity and convenience of production systems. In particularly the hydraulic systems using hydraulic fluid have higher power outputs than those of other systems, which is why they have long been used in construction and machinery industry. Among hydraulic equipment, the...
This paper shows technique of the fluid analysis with the experimental evaluation in the fish type robot. Specifically, the driving force of the fish type robot swimming with a water tank is measured, and mesh necessary for fluid analysis is made by the picture of a fish model robot photographed parallel to the experiment. The method of the analysis is a new fluid analysis technology for analyzing...
The variation of pressure of the blood is a key parameter in the development of ventricular assist device. This latter is useful in order to synchronize the behavior of the actuator with the cardiac frequency. This paper presents a sensor made of a dielectric electroactive polymer (DEAP). A particularity of this sensor is the special tubular shape, similar to an aorta, which allows to be used for...
Free form surface modeling is one of the most advanced procedures of creating digital models in CAD. Use of free surface for creating solid models has become increasingly relevant in terms of technological possibilities of production in the subsequent phases of the product lifecycle. Multi-axis computer-controlled machines are standard even in small workshops and rapid prototyping is undergoing progressive...
The analytical models for optical imaging of internal structure of controlled objects with complex shape were considered and, on their basis, the distortions, appearing in the image depending on visualization system's parameters and emitting source type, were analyzed.
Accurately predicting warpage using finite element simulation helps accelerate decision-making in the early product development phase. With the ongoing trend of thinning the overall thickness of the microelectronics package as well as its substrate, copper with high modulus and coefficient of thermal expansion becomes more prominent compared to the rest of the non-metallic material. Package warpage...
Previous coflow scheduling proposals improve the coflow completion time (CCT) over per-flow scheduling based on prior information of coflows, which makes them hard to apply in practice. State-of-art information-agnostic coflow scheduling solution Aalo adopts Discretized Coflow-aware Least-Attained-Service (D-CLAS) to gradually demote coflows from the highest priority class into several lower priority...
A number of model-pulses to be used for feeding purposes in time-domain, electromagnetic simulations are compared. The pulses' causality and temporal support are employed as discriminating features. CST Microwave Studio® simulations of a canonical configuration are employed for assessing the pulses' suitability. In view of their entailing numerical accuracy and short temporal signatures, the time-differentiated...
Small cells and device-to-device (D2D) communications will play a vital role in the realization of the next generation of wireless mobile communication systems (IMT-2020 or 5G). Both of them involve transmitters and receivers less than 10 m high inducing a more complex urban environment. This paper presents a framework of integrating composite urban furniture, e.g., traffic signs, traffic lights,...
A method is developed and introduced into simulation of waveforms scattered by a spherical shell covered by a visco-elastic layer. Both forward and backward scattered waveforms are investigated. Comparisons of the results and those without the visco-elastic layer show that the forward scattering strength is hardly affected by the visco-elastic layer no matter in a low or a high incident frequency,...
In early stage of the design process, modelling is a crucial phase because it allows the designer estimating the device performance before fabrication. Very often, this phase is performed with use of FEM simulator that is usually time consuming. In many cases, especially when simple structures are used, the use of analytical model is more convenient. In this paper we present an analytical model of...
This paper describes a procedure to get a vibrational model of a combustion chamber from a gas turbine, with the purpose to set the basis of a future acoustic phenomenon analysis. The combustion chamber model is grounded in a sub-damped modal model in which its freedom degrees are according with its flexible modal modes and their corresponded natural frequencies which were gotten from impact tests...
Existing facial expression recognition (FER) algorithms aim to extract discriminative features from a face. These discriminative features can be extracted only from the informative regions of a face. In this view, several face models are proposed which are mainly intended to extract geometrical features from a face, and hence these models may not be suitable for extract discriminative texture features...
The purpose of the article is to investigate the problem of recognition of plant objects using research methods of graph theory and analytic geometry. The process of plant object recognition may be based on the analysis of their general structure. In this paper, we propose an approach based on the construction of models of plant object structure in the form of graphs. It is proposed to consider the...
This paper considers the practical nuances of using current source gate models in an industrial statistical timing analysis environment. Specifically, the memory overhead of a naive implementation combining statistical and current source models to obtain and store gate output waveforms is found to be impractical for large microprocessor designs. A study is performed to observe variational gate output...
Key markets, such as automotive, wearables, and internet-of-things (IoT) are spearheading the drive to realize more sophisticated packaging technologies that include the growing use of interposers and 3D ICs. With the goal of improving processing performance, increasing clock speeds, and reducing power consumption, design teams are challenged with ensuring signal quality, power delivery, and thermal...
Development in the field of very large scale integration (VLSI), over the past decade flooded the market with video cameras, which increases the installation of camera for surveillance purpose. Due to this huge amount of data is augmented per day, which is either impossible to handle manually or to store for too long period. These create the need to find out an algorithms and methods for automatic...
Detection and segmentation are two strongly correlated tasks, yet typically solved separately with different techniques for repetitive patterns or simultaneously solved for generic patterns. We propose a Simultaneous Detection and Segmentation model for Repetitive pattern analysis (SimDSR) in real-world images. The proposed SimDSR model implements a joint patch-contour alignment between the multi-scale...
