In deregulated environment (DE), available transfer capacity (ATC) calculation is a crucial matter in the power system operation and it is a key in view of trade of electricity. In this paper, it is emphasized to the calculation of ATC with the help of optimal power flow (OPF) method along with different soft computational techniques viz. particle swarm optimization (PSO) and biogeography-based optimization (BBO). The ATC is the deciding factor on the base of the effect of transaction on transmission to allow or disallow bilateral transmission transection. The OPF has many objectives in DE with open market situation and these calculations aid to independent system operator (ISO), to handle the congestion threat over transmission lines and assure security and reliability. The two methods of soft computing i.e. PSO and BBO have been adopted to figure out the aforesaid criteria in ATC calculation through OPF, a corrective technique, which hints new generation schedule to resist congestion and gives clues to tune the controlled parameters (e.g. tap setting, reactive power injection etc) to avoid the violation of power system constrains (bus voltage limit and reactive power injection limit etc. In this paper, PSO is implemented to evaluate ATC then BBO for the same. The proposed methods are tested on IEEE 30 bus test system and their results are compared and is it observed that BBO results is better than that of PSO.

Orientation and Rotation of a system plays an important role in describing how an object is placed in 3-D space. Measuring an orientation has many application in the field of Monitoring human motion, Animation, Unmanned Aerial Vehicle (UAV), Robotics and Navigation. An AHRS (Attitude and Heading Reference System) is commonly used for measuring the orientation through which Roll, Pitch and Yaw of the system is obtained. This paper proposes a design of Wireless AHRS (WAHRS) which is capable of sending the sensor data to the ground station, using the Ultra-low power nRF24L01 transceiver, HC-05, Atmega328p and the MARG (Magnetic, Angular Rate, and Gravity) MEMS (Micro-Electro-Mechanical Systems) sensor. The nRF24L01 is a cost-effective radio transceiver which operates at a frequency of 2.4 GHz Industrial, Scientific and Medical (ISM) radio Band. The received data is further processed for analysis, data visualization and decision making. Quaternion is used for representing orientation and rotation as it has an advantage over 3-D algebra.

Gallium phosphide nanowires (GaP-NWs) were synthesized via oxide assisted growth mechanism in a chemical vapor deposition (CVD) and their optoelectronic properties were studied. The diameters of nanowires were in the range of 20-80 nm and lengths extended up to tens of micrometers. Raman spectra studies of GaP-NWs reveal broad and intense peaks at 364 and 398 cm-1 confirmed from transverse optic (TO) and longitudinal optics (LO) phonon. High resolution (HR) X-ray diffraction (XRD) reveals an addition peak that indicates presence of silicon in chemical network of GaP-NWs. Photoluminescence spectra shows intense PL peaks, indicating their potential applications in optoelectronic devices.

In this paper a shorted planar meander-line metal antenna (SPMMA) is designed at 2.45 GHz by modifying the radiating element of a shorted planar rectangular metal antenna (SPRMA). The shorting strip reduces 40% size of the meander-line antenna and the size of the SPMMA is 16% shorter compared to that of SPRMA. The reflection coefficient, gain and efficiency of the SPRMA and SPMMA are compared. The proposed compact meander-line metal antenna yields reflection coefficient of -39 dB, absolute gain of 2.7 dBi and efficiency of 90% at 2.45 GHz which makes this antenna suitable for ISM band applications. The normalized radiation pattern in E plane of the SPMMA is shown. The parametric studies are carried out to realize the effects of design parameters of the proposed meander line antenna on its reflection coefficient characteristics.

This paper demonstrates the design of analog circuits using simulated I/V data of a sample device (PMOS/NMOS), and estimation of transconductance (gm) from this plot using approximation. Proposed design technique is based on the fact that the ratio of transconductance (gm) is inversely proportional to the MOS gate-source voltage (VGS). From the amplifier specifications, bias current and the load (or DC drop across the load) are generally estimated which in-turn is used to predict the device size. Proposed method is not only technology independent, it is also free from complex mathematical expressions associated with the device as it employs plots generated from simulators, Instead of analytical methods usually based on square law, which is unfit to capture sub-micron characteristics. When simulator is incorporated in the design process, analysis of the designed circuit, using the same simulator, is expected to match the desired performance closely. Using this simple approach, design time becomes shorter and a workable design can be made very quickly. An example amplifier circuit is designed using the proposed method, and simulation results are presented.

An area efficient temperature sensor using Ring Oscillator (RO) is proposed. It is basically implemented with two ROs, one being temperature-sensitive and the other temperature-insensitive. Temperature measurement is done in two steps. Initially, temperature-to-time conversion is performed when temperature-sensitive RO is enabled and then time-to-digital conversion is performed when temperature-insensitive RO is enabled. This two step process optimizes the area because only one counter is sufficient. The feedback provision enables only one RO at once, providing low dynamic power dissipation. A True Single-Phase Clock (TSPC) based high speed counter is employed to meet the requirement. It is designed using UMC 0.18 μm CMOS technology with the supply votage of 1.8 V and the simulation results are presented. The proposed sensor is capable of measuring the temperatures from -55° C to 125° C with the resolution of 5.68 LSB/°C. It dissipates 650 μW with the conversion rate of 300K Samples/S and occupying 10.05 μm2.

ZnO nanorods have been grown on indium tin oxide (ITO) coated flexible polyethylene terephthalate (PET) substrates by a hydrothermal method. Hybrid photosensing devices have been fabricated with S and N co-doped graphene quantum dot (SN-GQD) sensitized ZnO nanorods and a conducting polymer poly (3-hexylthiophene) (P3HT). The photoresponse behaviors have been investigated for hybrid devices with and without GQD attachment. SN-GQD sensitized nanorod based device demonstrated superior photoresponse and higher incident photon to electron conversion efficiency (IPCE) than pristine ZnO nanorods.

Estimation of magnetizing reactance of Induction machines are very much essential for accurate computation of their performance and for calculation of their efficiency. The reactance of the magnetizing circuit is very much nonlinear in nature. It changes on the variation of load or type of operation like motoring operation or generating operation. This paper presents the iterative method to calculate the reactance of magnetization curve and then comparison is made for the performance of machines with three different magnetic materials for the magnetic circuit. MATLAB coding is used to compare the performance as Generator as well as Motor separately.

With the advancement of wireless communication and popularity of internet, security of transmitted data has become a major area of concern and have attracted many researchers. To prevent unauthorized access, it is important to encrypt 1D either 2D (image) data before transmission over open wireless network. A5/1 ciphering algorithm is one of the highly secure encryption algorithm, widely used in GSM standard over wireless network to provide security for the voice data. In order to achieve high security and efficient utilization of existing technology and available resources, the same algorithm can also be used for image and video encryption over wireless channel. In this paper, Enhanced A5/1 cipher based image encryption technique with image bit plane separation is proposed to enhance the security of image data transmitted over wireless network. In this method gray scale image is separated into eight different biplanes and each separated 2Dbit plane data is converted into 1D data stream. Each data stream is XORed with a key stream generated by stream cipher whose length is equal to the resolution of the image i.e., rows * columns. Enhanced A5/1 stream cipher with improved clock controlling unit and highly nonlinear combining functions is initialized using a 64 bit secret key to generated key stream. For encryption, eight different key streams are used for an image. The proposed method shows high encryption quality, improved differential analysis values, lossless encryption and decryption and fast computations with respect to the standard AES algorithm used as a benchmark.
