In recent years, several meta-heuristics have proved their effectiveness in solving combinatorial problems such as hardware / software partitioning. In this paper, we present a synthesis of main meta-heuristics: local search methods and evolutionary algorithms. We offer an analysis of these meta-heuristics by identifying the fundamental ideas guiding the choice of a meta-heuristic in practice.
The traceability is a means to minimize the size of recalls and the production process. It is an emergent topic of research to improve the production efficiency. Some governments force the traceability on companies like a management tool of the risks in order to protect the public health. The objective of this work is to evaluate the impact of the RFID and WSN on traceability. We presented a categorization...
In this article, we propose a new approach to study a suitable structure of metamaterial antennas for RFID technology that operates in the UHF band. This antenna is constituted by a dipole associated to a network specific and homogeneous structure composite of circular split ring resonators that can produce a negative permeability. Thanks to the effect of effective negative permeability, we can improve...
Clubfoot is a complex deformity found in one in a thousand children. It frequently causes disability — either from the original deformity or because of secondary conditions and problems associated with treatment. Recently, many pedorthsis supporting orthotics deformity in a foot have been evolved. Unfortunately, such pedorthsis need patients to involve in many doctor visits. The advance in wearable...
In this paper, an efficient method is presented to synthesize directive beam and multi-beam patterns. An optimal radiation pattern is obtained for a linear antenna array using Taguchi's Optimization method. A set of phase shift weights are generated in order to steer the beamforming towards any desired direction The results of Taguchi's method are validated by using array antenna patch and simulated...
The General Purpose GPU computational model changes the way parallel processing can be achieved. It is becoming more attractive to carry out parallel tasks on GPU devices. The sequential part of the application runs on the CPU whereas the computationally-intensive part is accelerated by the GPU. GPUs provide a multithreaded high level of parallelism with hundreds of cores. For high performance computing...
The developments in modern technology have altered the way people survive and assume knowledge. This in turn has produced a fresh challenge to the way a current classroom is carried, thus the flipped classroom appears as the most appropriate access to the present learning environment. The core and precept of a flipped classroom will be presented in this paper as well as the consequences and impact...
Today, RFID systems, which are implanted in the body for the communication, cannot transmit medical data in several meters range[1]. In this section the aim is to study the implantable device systems activated for long range by transmitting the signal without electromagnetic thread[1].
The aim of this research is to understand the role and efforts of financial institutions in boosting e-banking in Pakistan and customers' perception towards the potential benefits and risks associated with electronic banking in Pakistan. It is constraint to Karachi only and the research is conducted to evaluate the factors that hesitates consumers using E-banking services and what efforts the financial...
Compared with conventional low earth orbit (LEO) synthetic aperture radar (SAR), geosynchronous SAR (GEOSAR) has the advantages of wider covered area and shorter revisit time, which have received much attention. In this paper, the performances of GEOSAR interferometry versus the main parameters of interest, including absolute and relative height accuracy, are analyzed in detail based on curved earth...
In this article we have presented a new design of a monopole antenna mobile phone, which covers several bands with circular polarization. The proposed antenna generates five resonant frequencies. Our antenna has a bandwidth band that has bands of wireless communication systems such as GSM (880 960 MHz), DCS (1710 1880 MHz), PCS (1850 1990 MHz), UMTS (1920 2170 MHz), WiBro (2300 2390 MHz) and ISM (2400...
In this paper, an implementation of quadrature amplitude modulation (QAM) on field programmable gate array (FPGA) is introduced. FPGAs offer superior speed. Implementation is done through hardware co-simulation; This co-simulation capability automatically creates bit streams to and from the FPGA and associates them with the corresponding System Generator blocks in the Simulink model. Thus, calculations...
Energy consumption is one of the major factors to be considered in wireless sensors networks (WSNs). In fact, routing protocols in WSNs are different than those applied in regular ad hoc networks since energy consumption is rarely considered in the latter. Sensors' clustering is a class of protocols where sensors are gathered into classes and only a cluster head is responsible for transmission to...
A remote DICOM (Digital Imaging Communication in Medicine) server needs an important storage and a high-speed network of, at least, 100 Mbps. This is a limitation for the storage and for remote access to images and image processing softwares. Objective: We set up, in this study, a secondary server that saves medical images of prostatic cancer patients compressed by JPEG 2000, the new standard of image...
This research paper reports in the Speech and Audio Processing Laboratory (SAP). Introducing the basic concepts of speech coding related to signal processing modules. The SAP Laboratory enhances the student's education through multimedia signal processing learning through speech and audio coding.
Image compression has attracted a lot of research since the beginning of Internet era and telecommunication. Enhancing image compression quality and ratio was achieved through several approaches such as neural networks and discrete transforms. However, other heuristic and bio-inspired methods such as genetic algorithms are still under experimentation. In this paper, we introduced a new image compression...
With the rapid development of E-business, enormous customer data is been accumulated daily in websites background databases. It is difficult to deal with by business systems due to the large number of online transactions Data mining techniques and tools can be used to analyze customers shopping behavior and consuming habits to better understand their needs and increase the profits of the organization...
Industrial control and automation systems are evolving towards infrastructures more connected. Its component's interconnection makes them more dependent on the networks and communication protocols used. On the one hand, high performance, low costs and real-time capabilities are generally required to cope with more and more demanding application requirements; while on the other hand, security solutions...
