Automatic Service Orchestration for e-Health Application
This paper describes an architectural approach to the development of dynamic service-oriented systems for e-Health using the service orchestration mechanism and semantic technologies. The main idea is the dynamic synthesis of the complex functionality required by user or by software agent. This idea should help to build and easily extend the applied loose-coupled systems without…
Read More Computational and Technological Models of Cognitive Monitoring Systems
The approach to the construction of promising cognitive monitoring systems is considered. Based on the analysis of known solutions, the problem of automatic synthesis of computational models of cognitive monitoring is posed. In the synthesis of models, it is proposed to reduce them to relatively finite operational automata. An example of a synthesized model of…
Read More Deep Feature Representation for Face Sketch Recognition
Face sketch recognition aims at matching face sketch images to face photo images. The main challenge lies in modality discrepancy between face photo and sketch images. In this work, we propose a new facial sketch-to-photo recognition approach by adopting VGG-Face deep learning network, with which face images can be represented by compact and highly discriminative…
Read More Design and Analysis of 32-bit Parallel Prefix Adders for Low Power VLSI Applications
The basic processes like addition, subtraction can be done using various types of binary adders with dissimilar addition times (delay), area and power consumption in any digital processing applications. To minimize the Power Delay Product (PDP) of Digital Signal Processing (DSP) processors is necessary for high performance in Very Large Scale Integration (VLSI) applications. In…
Read More Photodecoloration of Methyl Orange Solution Assisted by ZrS3 Powders
Zirconium trisulfide ZrS3 is a representative of transition metal polysulfides containing sulfur as S–1 in polysulfide, usually disulfide S22– groups. Semiconductive zirconium trisulfide which absorbs visible light near UV edge was considered as a possible photocatalyst. We experimentally studied photodecoloration of methyl orange in presence of ZrS3. It was shown for the first time that…

This work presents new pipeline-parallel, generic and configurable parallel hardware architectures for the Direct/Inverse Wavelet Packet Transform (DWPT/IDWPT) independent of any specific family of wavelets, implemented in FPGA technology using a parallel architecture of direct FIR filter. We propose in the following paper, new P-parallel structures for the DWPT and IDWPT transforms based on the…
Read More A Comparison of MIMO Tuning Controller Techniques Applied to Steam Generator
This work presents a comparison between controller tuning methods for a multivariable steam generator. Controller tuning has a remarkable impact on closed loop performance. Methods selected were Single-Loop Tuning (SLT), Biggest Log Modulus Tuning (BLT), Sequential Return- Difference (SRD) and Structured H(inf) Synthesis (S-H(inf)). Method assessment takes into account set-point tracking, disturbance rejection, tuning effort and…
Read More Direct Torque Control Strategy Based on the Emulation of Six-Switch Inverter Operation by a Four-Switch Inverter Using an Adaptive Fuzzy Controller
This paper presents a novel direct torque control (DTC) strategy aimed to four-switch three-phase (FSTP) inverter-fed an interior permanent magnet synchronous machine (IPMSM), using a fuzzy logic toolbox in speed control loop. In fact, the introduced DTC approach is based on the emulation of the operation of the standard six-switch three-phase (SSTP) inverter. This fact…
Read More Co-designed accelerator for homomorphic encryption applications
Fully Homomorphic Encryption (FHE) is considered as a key cryptographic tool in building a secure cloud computing environment since it allows computing arbitrary functions directly on encrypted data. However, existing FHE implementations remain impractical due to very high time and resource costs. These costs are essentially due to the computationally intensive modular polynomial multiplication. In…

In this paper, we investigate the decentralized control problem for largescale interconnected systems. The synthesis of the decentralized controller consists in determining gains which ensure the stability of the global system. To calculate these gains, three approaches are presented. Our main contribution is to develop a new decentralized stabilization approach which the decentralized local gains…

This work is dedicated to present a new pipeline-parallel architecture of Discrete Wavelet Packet Transform (DWPT) for all wavelet family implemented in FPGA technology. The main target of our architecture is to provide an effective performance trade-off, where it significantly increases the throughput with a restricted amount of hardware. In this article, we propose two…
