A new approach of the iterative method WCIP (Wave Concept Iterative Process) using the technique of the auxiliary sources considers a pixel or a unit cell in a periodic structure as an electrical circuit instead of a sub-domain representing metal or dielectric in the classical iterative method. The intersection of this new approach with the old is on the application of the iterative process in waves between the space and spectral domains in order to calculate the electric field and the density of current. The novel approach is introduced by the study of two types of defects on an uniform transmission line. The first one is a defect of a resistance, the other is a defect of a reactance. The results of simulation of the variation of current along the transmission line are agree with the theory which validates our proposed approach.

The fuzzy vault is a promising cryptosystem for the protection of fingerprint templates. However it requires the alignment of the query template to the enrolled one. Most existing implementations either rely on the extraction of the core which is not a guaranteed task, or use publicly available helper data which may leak information about the protected minutiae. We propose a new alignment approach for the fingerprint fuzzy vault based on distortion invariant minutiae features. Experimental results show improvements in genuine and false accept rates over previous implementations.

The weaknesses of sensors with mobility arise major challenges especially in routing. Routing in WSNs is among the NP-hard optimization problem that requires efficient and robust methods such as metaheuristics. The ant colony optimization (ACO) and the particle swarm optimization (PSO) are the most used metaheuristics for solving this problem in static WSNs. For dynamic WSNs, the model random waypoint (RWP) is widely proposed to evaluate the performance of mobile networks. In this work, we present a new evaluation of the RWP model impact on the ACO and the PSO-based routing protocols for WSNs, using different parameters like the number of nodes, simulation time and simulation area. Further, this study compares the performance of the ACO and the PSO routing protocols for mobile WSNs.

In this paper, a new metamaterial-inspired high frequency surface wave antenna is designed. An artificial magnetic conductor surface is introduced into the near field region of a vertical meander monopole antenna to improve its electromagnetics performances, where a split ring resonator-cell is selected as an artificial magnetic conductor. The return loss, the radiation pattern, the electric field distribution and efficiency are evaluated through the finite element method (FEM simulations). The designed antenna has advantages of low cost, small size, and light weight.

Massively Multiplayer Online Games (MMOG) keep attracting hundreds of thousands of players from all over the world. Ensuring a scalable and latency-sensitive MMOG service is a challenge task since it is subject of high workload variability. Traditionally, MMOG providers used to over provision resources in order to cope with worst workload scenario. Nowadays, MMOG infrastructures have switched to Cloud computing paradigm. In this paper, we propose a novel architecture for MMOGs and we address the problem of dynamic resources provisioning over a distributed cloud infrastructure. Our contribution allocates necessary virtual resources while managing the trade-off between resource allocation cost and processing delay constraint. Experiment results prove effectiveness of our proposition.

In this paper, the performance of a rectangular microstrip patch antenna fed by a coaxial probe has been enhanced by perforating elliptically periodic holes in both substrate and resonant element. A parametric analysis of the required number of holes and their dimensions are carried out, in order to increase the gain. The proposed antenna was designed and simulated by CST Microwave Studio. Obtained results that concern the return loss and radiation patterns show the significant enhancement of the antenna gain for the same operating frequency.

A dual-microphone noise reduction method based on the coherence function for mobile communications is suggested in this paper. The proposed algorithm exploits the Kalman filter and the spectral subtraction method in order to improve the speech quality in different noisy environments. The adopted method is easy to implement and needs no estimation of interfering signals statistics. The proposed algorithm is tested with different distances between the two microphones using recorded data and objective criteria such as: PESQ and SNR. The good performance of the suggested algorithm and its low complexity, making it a promised solution for dual-channel mobile phones.

In this paper, an efficient approach is proposed to track the double-selected multipath channel for a Multiple-Input-Multiple-Output Orthogonal-Frequency-Division-Multiplexing (MIMO-OFDM) system in the existence of both Gaussian and non-Gaussian noises interfering with reference signals. Using nonlinear complex Multiple Support Vector Machine Regression (M-SVR) methodology, fast-fading multipath channel estimation can be performed accurately. The M-SVR algorithm is developed and affected to MIMO Long Term Evolution (LTE) downlink system with Space Time Block Coding (STBC) scheme. The effectiveness of the proposed technique is demonstrated through the obtained simulation results which confirm the abilities of the M-SVR to track the fast-fading channel in the manifestation of several nonlinearities.

Video compression techniques play a vital role in storage and transmission of data through the limited bandwidth capability. This study proposes a compression method that can obtain a highest compression ratio and high quality for video compression. The proposed method consists of five phases. In the First phase, the main frames from the digital video through opening the header of video are split using ASCII long function. The Second phase is to transform colors from RGB to YUV color space, which consist of two main components the luminance (Y) and the chrominance (UV). In the third phase, Discrete Cosine Transform (DCT) and Motion techniques are combined to generate the new method and to reduce the spatial and temporal redundancy. In the next phase, the DCT coefficients are coded using Embedded Zerotree Wavelet (EZW) algorithm. Finally, Run Length Encoding (RLE) technique is used to encode the symbols sequences. The proposed method splits movie file based on the skew measurements with a specific threshold determined by the EZW algorithm. The proposed method confirms that the EZW algorithm is effective compression algorithm.

In this work, the Fuzzy kNN (FkNN), an alternative of the standard kNN algorithm, is used for Timit phoneme recognition. Phoneme is the smallest unit that composes speech. For this reason, if phoneme recognition is performed, it can achieve a significant word and text recognition. Thus, the main idea consists on assigning phoneme membership to the data phonemes by measuring the distance to its kNN. FkNN compute the fuzzy distances between the data phonemes that define the cluster fuzziness. Mel Frequency Cepstral Coefficients (MFCC) associated with their first and second derivatives and energy coefficient were extracted from the speech signals as an input of the recognition system. A comparison of a crisp and fuzzy kNN was performed. Experiments show that FkNN algorithm not only can lead to significant recognition rates, but also may supersede in some ways Hidden Markov Model (HMM) the reference of speech recognition.
