Modeling properties and functions associated with DNA sequences is a very complex task in genomics. This task is more and more difficult when it concerns the human genome. This genome is composed with coding and non-coding regions which are not yet fully identified. Difficulties seen in this context are particularly related to the fact that 98% of the human genome is made up of non-coding zones. Therefore it seems evident that a powerful predictive model can have a huge advantage in advancing the exploration of the human genome. In this paper, we started from text representation of the DNA sequence to the representation of exons and introns by images to classify them. Here we are introducing a convolutional neural network model to classify human exons and introns. Our model has shown very good results concerning classification learning and testing rate which exceed 90%.

This paper describes an implementation of a band-pass sigma-delta modulator behavioral model in Simplorer VHDL AMS. The model includes most of the non-idealities which affect the performance of the component, such as sampling jitter, kT/C noise and operational amplifier parameters. A comparison with another model, implemented in MATLAB SIMULINK by Brigati et al., is made to highlight and validate the proposed model. The spectrum plot and the Power Spectral Density of the output signal are also presented to evaluate the characteristics of the modulator model. Simulation results obtained using a second-order band-pass sigma-delta modulator demonstrate the validity of the model by the mean of estimating signal-to-noise and distortion ratios and some non-linearity errors such as differential non-linearity and integral non-linearity.

Recently, the operation of solar supplied wireless sensor nodes became dependent basically on implementing prediction algorithms for the expected harvested solar energy. These prediction algorithms contribute to saving energy. Thus, extending the lifetime of that sensors through utilizing the saved energy later. Among different prediction algorithms, the moving average based ones are the most used for their simplicity with limited resources in systems like sensor nodes. The basic moving average algorithm, Exponentially Weighted Moving Average (EWMA), is appropriate only to predict energies for symmetric days. Thus, it shows significant prediction error at times of sudden weather fluctuations. The other moving average algorithms, Weather Condition Moving Average (WCMA) and Pro-Energy show considerable errors specifically at sunset and sunrise times with a preference for the last one. This paper proposes a new moving average algorithm, named (EWWC), to eliminate the overall daily prediction error by combining two moving average algorithms (EWMA and WCMA). For two weeks, one in summer and another in winter, EWWC shows an average prediction error of (16.3%, 20.5%) while (EWMA) and (WCMA) show (21.2%, 25.1%) and (17.9%, 22.1%), respectively. This means that EWWC has an improvement of 1.6% in both weeks. Thus, it is recommended to be used for predicting energy in solar-powered sensor nodes.

In this paper, a guaranteed cost based on novel sliding mode control (SMC) for a class uncertain nonlinear time delay systems has been proposed through the T-S (Takagi and Sugeno) models. First of all, a new sliding manifold has been developed to remove the restrictive assumptions in the most of the existing fuzzy sliding mode control approaches. In addition, we took into account the delayed state in the sliding function in order to improve the performance behavior. Furthermore, a good performance can be ensured by choosing an appropriate cost function. The asymptotic stability condition of the closed loop system as well as the sliding mode controller design have been ensured based on LMIs (Linear Matrix Inequalities) formulation. Finally, the obtained simulation results prove the efficiency of the proposed control scheme.

A major problem in Switched Reluctance Motor (SRM) is torque ripple. This latter causes undesirable acoustic noise and vibration. Thus, to attenuate the oscillations amplitudes, we propose solutions exploiting the Indirect Instantaneous Torque Control (IITC) and considering the speed and load variations are proposed in this article. Using the simulation results provided by the execution of the behavioral model developed based on the finite element method, we determine the SRM static and dynamic characteristics. The proposed method efficiency is also demonstrated and verified through simulations.

This paper deals with the integration and analysis of two different maximum power point tracking (MPPT) control methods, which are tested under temperature and irradiance variation. These MPPT methods, designed by fuzzy logic control (FLC) and Particle Swarm Optimization algorithm (PSO), have been created for photovoltaic systems (PV) and simulated to obtain the various system responses such as: duty cycle, voltage and power. A comparison between the performances of the FLC and PSO algorithms have been completed to confirm the best characteristics of FLC method in terms of rapidity, precision and simplicity.

In this paper, we have proposed a robust and computationally inexpensive threefold algorithm used for the detection of moving objects in a video sequence. The adopted algorithm starts with computation of difference between images using modified temporal difference. Images differencing are calculated by subtracting two input frames, at each position of the pixel. Instead of generating image differencing using the traditional continuous approach, we have proposed to use a fixed and modified number of alternate frames centered on the current frame. This approach aims to reduce the computational complexity without compromising on image differencing quality. Object segmentation is finally performed on the refined difference image by the Otsu's algorithm. The evaluation tests show that the proposed approach reaches the better performance of detection compared with other approaches.

Recently, Vehicular Ad-hoc Networks (VANETs) are in the initial stage of their deployment. Protecting drivers' privacy is one of the most critical problems raised by researchers. VANET users would not accept building location profiles of the movements of their vehicles. To that effect, solving this issue is of significant concern. Pseudonym switching and radio silence techniques are among the widely accepted privacy protection solutions in the literature. Radio silence intervals have a considerable impact on the efficiency of the proposed schemes. In this paper we will evaluate the performance of some known pseudonym switching schemes under different radio silence periods.

The mechanical force imparted by industrial robots is enormous and can lead to dangerous situations for human workers and property if they malfunction. System designs based on the redundancy concept are essential to avoid or mitigate the resulting risk, which is recommended by the various safety standards. In this paper, a 1oo2D based safety SoC that provides multiple Ethernet communication interfaces is presented. Two different design approaches are implemented using the in-house FPGA development board based on the LEON3 soft processor. The software algorithms for each approach are developed and verified.

This paper is dedicated to the model predictive control (MPC) for constrained discrete time systems with additive uncertainties to track a references system. The tracking MPC problem distribute a control law appropriate for regulating constrained uncertain system to a given target system. Though, when the target operating point changes, the feasibility of the controller may be lost and the controller miss to track the reference. In this paper, a novel MPC for tracking variation system references is introduced. The main issue consist to minimizing a cost that penalizes the error between the state of the original system and the reference system state, taking into account, an polyhedral invariant set for tracking is considired as extended terminal constraint. The properties of the proposed controller has been tested in two example. Simulation results show that the proposed tracking MPC successfully achieves robust tracking in terms of control performance.
