In the research of past one decade it has been quite convincingly shown that the boundary conditions in particle swarm optimizers are an important algorithmic part which restricts the particles within the solution space thereby increasing their scope of participation in solution finding process. Usually, velocities of the particles are regulated to bring them back to solution space; here a different fundamental approach of regulating the position of particles is taken, particles which go out of solution place are relocated inside by maintaining symmetry about the boundary. A six element linear antenna array is taken as the optimization target for the placement of nulls in some specified angles and an overall reduction of side lobes in the radiation pattern. Results show better performance of this boundary condition over other established ones in terms of quicker convergence and obtaining better optimization solution.

The simulation of a DPSK modulator, demodulator and power telemetry for Epi-retinal and neural prostheses is presented in this paper. The technique adopted in this method is DPSK telemetry system with a 22 MHz input frequency. A quad level power telemetry system is to generate high and low voltage outputs to the stimulators. To add flexibility to the stimulator, each pixel has a local digital controller, which enables the stimulator IC to generate 256 parallel stimulations with various pulse widths and amplitudes. The proposed retinal stimulator circuit is designed in 180nm technology using cadence virtuoso analog design environment. The DPSK transmitter, DPSK receiver and power telemetry consumes 93.7μW, 98.3μW, 8.554μW respectively at 1.8V and area occupied for the transmitter and the telemetry is 0.00113mm2 and 0.000648 mm2.

Ultra-wideband (UWB) technology offers a promising solution to the RF spectrum drought by allowing new services to coexist with current radio systems with minimal or no interference. This coexistence brings the advantage of avoiding the expensive spectrum licensing fees that providers of all other radio services must pay. In Ultra Wide Band technology, the conventional analog waveform is a simple pulse which in general is directly radiated to the air. These short pulses have typical widths of less than 1 nanosecond and thus bandwidth of over 1 GHz. Due to this wide bandwidth, Federal Communication Commission(FCC) has imposed certain restrictions on the emission limits of UWB systems. Inorder to fit well to the FCC mask, the basic pulse shapes have to be modified. So pulse shaping is very much relevant in UWB domain. The immediate objective of this paper is to design an optimal pulse shaping technique. This paper proposes a hybrid approach for UWB pulse shaping which utilises ideas from existing two techniques.

Interference Lithography is a developing technique for producing micro/nano array pattern structures over large areas. This paper focus on generation of nano/micro feature size patterns using four-beam interference lithography technique. The generated periodic array pattern structures are developed using MATLAB. The interference parameters in FBIL include wavelength (λ), slit separation (d), angle of incidence (Θ), distance between slit and screen (L) and depth of penetration (DOP). We have simulated and modelled the four beam interference lithography technique by varying interference parameters to produce various feature size patterns over the surface of the substrate. The obtained pattern structures have the periodicity of 0.75 μm for 1064 nm, 0.39 μm for 565 nm. Depth of the focus is found to be 0.235 μm for 1064 nm and 0.125μm for 565 nm. Highest value of depth of penetration is observed to be 0.552 mm and 0.586 mm for 1064 nm and 565 nm respectively. The study of FBIL shows depth of penetration increases with decrease in slit separation. More complex patterns can also be produced on varying the position of beams, angle of incidence and number of beams. FBIL can be applied in fabrication of 3D photonic crystals, magnetic storage, solar cells, waveguides, calibration grids, OLEDs and functional surfaces of sensors.

This paper deals with a simulation analysis of Power Factor Correction (PFC) in BLDC motor drives using type III cuk derived converter. A power factor corrected converter is required for improving power quality at the AC mains of an inverter fed BLDC motor drive. Conventionally, the BLDC motor is fed by a diode bridge rectifier (DBR) which results in highly distorted supply current and a poor power factor. A new bridgeless single-phase ac-dc Cuk derived topology has been introduced for power factor correction. This bridgeless topology uses minimum number of switches and thus reduces the less conduction losses compared with the conventional PFC rectifier. There are three Cuk derived configurations for power factor correction. In this paper, all the Cuk derived topologies are investigated and compared. The best topology is modelled in MATLAB/Simulink platform and the results are analysed.

The ever-increasing demand of vehicular mobility in today's life over loads the existing road transportation infrastructure and resources, for which a robust solution in the near future lies in effective utilization of currently available means of road transportation and infrastructure. For this purpose, development of Intelligent Transportation Systems (ITS) technologies that contribute to improved traffic flow stability, throughput, better utilization of infrastructure and safety is needed. In today's traffic, to achieve the safe inter-vehicle distance, avoid congestion and improve safety, the limited human perception of traffic conditions and human reaction characteristics constrain should be analysed. In addition, erroneous human driving conditions may generate shockwaves in addition which causes traffic flow instabilities. In this paper to achieve regulated inter-vehicle distance and improved throughput, we consider Cooperative Adaptive Cruise Control (CACC) system, for vehicle string. Information of individual vehicle is exchange between vehicles through wireless communication in addition can give better performance. By introducing vehicle to vehicle (V2V) and vehicle to roadside unit (V2R) communications, the vehicle gets information not only from its preceding and following vehicle but also from the vehicles in front of the preceding one and following one.

Image processing and Pattern Recognition are very much important in the extraction of clinical information from images. A hybrid image processing method is presented based on spatial fuzzy C means clustering combined with parametric deformable model for CT liver images. The Spatial fuzzy c-means using pixel classification and parametric deformable models are utilizing dynamic variational boundaries for image segmentation. The controlling parameters of parametric deformable model evolution are also estimated from the results of clustering. Thus we can improve the segmentation of liver image thereby increasing the detection of tumour effectively. Also we can segment out the liver and the tumor with increased efficiency and robustness.
