The particle swarm optimization PSO is an attractive domain for community looking to enhance time for optimal solutions. Several works will be done for SW or SW/HW implementation. The latter often gives better performance. In this paper, we present a comparative study of these various solutions and we focus on the FPGA ones. Our approach is based on a codesign methodology which adjusts performance parameters at design time.

Pulsed wave Doppler ultrasound is commonly used in the diagnosis of cardiovascular and blood flow abnormalities. Doppler techniques have gained clinical significance due to its safety, real-time performance and affordability. This work presents the development of a pulsed wave spectral Doppler module, which was integrated into a reconfigurable ultrasound system. The targeted system adopts a hardware-software partitioning scheme where an FPGA handles the front-end and a PC performs the back-end. Two factors were considered during the design. First, the data transfer rate between hardware and software should be minimum. Second, the design should use as few of the FPGA resources as possible. Accordingly, the processing was divided after the range gate integration where the data rate drops significantly. In addition, a quadrature demodulator was used based on a switching mixer and a cascaded integrator comb filter. The design was implemented and integrated into the targeted system. The system was tested using a string phantom and on human volunteers. The results showed that this simple design could achieve performance comparable to designs that are more sophisticated. However, it is limited by the number of available frequencies. Hence, it is suitable for systems with limited resources such as handheld systems.

This paper presents a solution using Zigbee network for improving energy efficiency inside railway vehicles, especially for suburban train and metro. We present firstly a comparison between existing wireless technologies and the choice for our platform. The simulation tools simuEM3D has been used to complete the experimental results. Then we present and analyze the results of the measurement campaigns in subway and suburban trains. Finally, the optimization of ZigBee propagation is proposed to reduce interferences between vehicles of the same train and interferences between nearby trains.

Methods of moving object detection for General Purpose Processors (GPPs) present an approach that does not allow a successful implementation in the Field Programmable Gate Array (FPGA). This is because correct pixel classification is directly related to the need for many resources in terms of memory or complex mathematical operations to model the reference image. Therefore, these implementations do not allow real-time processing. In addition, these methods implement only conventional techniques of digital imaging processing. Thus, we propose an architecture for FPGA that combines filter operations with fuzzy integral to improve the detection of moving vehicles. This proposed fuzzy decision system for detecting moving vehicles seeks to not compromise the results in terms of pixel classification, even validating the system through a reference image obtained by a simple modeling mechanism. Results are verified in terms of the resources occupied, maximum frequency of operation and similarity measure in the FPGA Spartan-6 LX100. The implementation of the proposed low-cost FPGA system processes high-definition images in real time and improves pixel classification.

The use of drone have been increased recently both in civilian and military operations. In this research, we investigate the coverage of a given area using a fleet of drone. Drones are equipped with on-board camera pointing down, an image sensor, whose objectif is to monitor a given area. Covering means that every point in the area should be covered at least by one drone. To achieve the full coverage area we define a new strategy based on the arc coverage. The problem is modelled and formulated as an integer linear program and has been solved optimally and tested successfully using the Solver CPLEX. Computational experiments are generated on different grid sizes.

This paper presents a novel approach that combines LIDAR and Stereo-cameras. First, a stereo camera is used to guide the extraction of road surface points from a 3D point cloud obtained by a LIDAR. Then, the number of points is reduced based on their elevation and illumination invariant colors. Finally, a post-processing is applied to have a projection in an image to obtain the final segmentation of the road. The method has been tested on three types of roads as defined in the KITTI benchmark. The obtained experimental results prove the effectiveness of our approach and its robustness in accuracy compared to existing approaches in the literature.

Breast cancer accounts for 16% of all cancers among females. Current early detection methods are expensive or computationally complex and thus unsuitable for developing countries. For this reason, a real-time fully automated Computer Aided Diagnosis system for Breast Cancer early detection from Ultrasound images is built in this paper. The proposed and implemented design comprises into its modules state of the art techniques and methods. The implemented design includes preprocessing/filtering of the input ultrasound image, segmentation of the region of interest from the background image and feature set calculation/extraction. Machine learning algorithms were implemented for classification of the tumour. Successful implementation with satisfactory run time is achieved with a final accuracy improved by 10% from previous work using the same set of features. Additional evaluation metrics like precision-recall plots and confusion matrices were also used to test and evaluate the system overall balanced performance.

This paper deals with the design of a new textile Radio Frequency Identification (RFID) transponder antenna for body-centric systems. The proposed antenna is a meander dipole operating in the Ultra-High Frequency (UHF) band with an overall size of 70*12*0.46 mm3 using three different materials: flexible copper foil, and ShieldIt Super and pure copper polyester taffeta conductive textiles as conductive parts. The wearable tags were analyzed in terms of antenna gain, reflection coefficient and surface current density through CST Microwave Studio software. Besides, wireless performance is evaluated so we can estimate the reading range at 4.3 meters at 915MHz.

QCA technology has considerable advantages in comparison with Complementary Metal Oxide Semiconductor (CMOS) technology, such as extremely low power dissipation, high operating frequency, and a small size and can operate at one Terahertz. The Multiply -Accumulator (MAC) unit is considered as one of the essential operation in Digital Signal Processing (DSP). In the real-time DSP systems, several applications like speech processing, video coding and digital filtering etc, require MAC operations. However, the power dissipation and area are the most significant aspects in these systems. In this paper, low power MAC Unit based on QCA technology is designed. QCADesigner ver 2.0.3 is used to validate the accuracy of the proposed circuit. The power dissipation is estimated using QCAPro tool. The total power consumed by this unit is 4.03 mW. It is found that proposed design is better than other designs based on classical technology. As the works in the field of QCA logic signal processing has started to progress, the suggested contribution will give rise to a new thread of research in the field of real time signal processing.

Memristor has become an interesting research subject in the recent years. Its special behavior has attracted the attention of the research community that motivated researchers to investigate it in details. As memristor is a relatively new electrical element, it is not yet available in the market as a solid state component Researchers found their way to build memristor emulators to achieve its pinched hysteresis. While many papers proposed floating emulators, only a few papers presented a grounded one. In this paper, an incremental grounded memristor emulator is proposed. The mathematical model of the emulator is discussed to match the theoretical model. Simulations are carried out to verify the circuit functionality. Parasitic effects have been studied for the proposed design. The emulator is very simple with only two current conveyors, one multiplier, and some passive elements. Experimental results showed a great match to the simulation results from SPICE.
