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.

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.

Wireless communication has captured the place which wired communication once held. One of the areas which has seen the large-scale implementation of wireless communication is the internet. People prefer to use wireless access to internet (WLAN) in place of wired and also expect the same level of service, reliability and performance as traditional wired networks provide. A common problem which is frequently noticed among WLAN users is the quality of signal or signal strength. To improve coverage in a particular area, many factors are to be simultaneously optimized. This paper presents indoor WLAN coverage analysis of the second floor of Electronics and Communication Engineering (ECE) Department of National Institute of Technology (NIT) Durgapur. The coverage calculation is based on the multiwall Motley-Keenan model. The Access Points (APs) which have been used are of the IEEE 802.11 n standard. A thorough analysis has been done to determine the setup of APs which would provide the best coverage in that floor.

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.

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.

Processing of the movement related task under planning by artificial means provides a means to those people whose natural modality of performing the task is bottlenecked by physical disability or neuro-motor disorders. Electroencephalography (EEG) based Brain-Computer Interfacing (BCI) systems can be defined to be a non-muscular pathway to operate rehabilitative devices using motor imagery signals captured from the motor activation areas in the brain. Supervised learning can help in prediction of motor imagery actions by processing raw EEG signals. However, dimension of the feature space plays a crucial role in this process. Large dimensional features not only increase the computational complexity but also the presence of redundant features causes reduction in classification accuracy. In this work, we intend to select the relevant features from the feature vector obtained by Power Spectrum Density estimation of the left/right motor imagery signals. BCI Competition 2008 - Graz dataset B has been used as the source of raw EEG data. To achieve this goal, we have used single-objective as well as many-objective version of Differential Evolution which optimizes the classifier's performance in terms of five metrics obtained from the Confusion Matrix. Support Vector Machine is used for fitness evaluation of the chosen feature subset as well as for classification of mental states. This work demonstrates the superiority of many-objective Differential Evolution in improving the accuracy due to reduction in feature dimension from an average of 60.56% to 82.60% while processing time of a test EEG sample reduces from 6.1 milliseconds to 5.6 milliseconds. The results obtained in this work are validated using Friedman Test.

A mathematical model for building energy systems (BES) is developed which maps the energy transfer processes occurring within the building space. Construction elements making up the building space and the heating and cooling plant responsible for thermal comfort of the occupants are also modeled. This involved quantification of linkages between temperature and humidity conditions and level occupancy (number of occupants, occupancy schedule) within building space. Thermal energy transfer processes of conductive, convective, and radiative heat balance for each surface of the construction elements and a convective heat balance for the building space are modeled. Building space zone is modelled for both sensible and latent thermal energy transfer. State space approach is used to model the building construction elements such as walls, with the parameters estimated using a nonlinear time invariant optimization algorithm with constraints. HVAC system is modelled with a control valve, heat emitter, occupancy driven ventilation controlled through a PID controller. A complete building energy system (BES) modeling procedure based on first principles of building physics is presented. BES model is simulated using MATLAB/Simulink and the results depict the temperature variations within the building space at less computational times.
