The university course timetabling problem (UCTP) schedules a set of events into timeslots and suitable rooms under various constraints according to the student enrollment such that the possibility of allocations is maximized. It is solved by introducing an innovative idea based on students groupings and then using ant colony optimization (ACO) algorithm. Disjoint groups of students, based on selected events, are created in such a manner that a student must belong to exactly one group. This procedure is executed by excluding the student from the further selection, once it is selected in a group. Events obtained after this grouping of students are assigned to timeslots and rooms by applying the ACO algorithm. The proposed algorithm is tested on a number of benchmark UCTP instances. The fitness function value is used as a performance measure. Each problem instance is run independently for several times and the solution among them with the least value of fitness function is selected as the solution of that problem instance. It is found that the proposed algorithm is computationally efficient when compared with other existing algorithms.

Due to the frequent usage of mobile phones these days, its harmful effects on biological systems has become a rising concern. Various international organizations like International Commission on Non-ionizing Radiation Protection (ICNIRP), U.S. Federal Communications Commission (FCC) and Institute of Electrical and Electronics Engineers (IEEE) have set safety guidelines on portable devices to limit the harmful effects of Radio Frequency (RF) radiations. Specific Absorption Rate (SAR) is a quantity that has been used by researchers to evaluate these safety limits on mobile phones. Exceeding these limits, leads to detrimental effects in biological systems. This paper discusses effects of RF radiations emitted by mobile phones on human body in terms of their SAR values. The SAR values are computed on human models to evaluate their effect on various body organs. Parameters affecting SAR values like age-related differences in RF absorption in human head models, mobile antenna tilt angle with respect to head and effect of using mobile phones inside elevators have been discussed. Moreover, methods for SAR reduction to limit RF exposure have also been analyzed.

The goal of this paper is to explore the effects of two dimensional photonic band gap (PBG) crystals substrate on the performance of a graphene based triangular nano patch antenna in terahertz region (1-3 THz). Graphene as patch conductor on photonic crystal has been used as substrate material for high bandwidth, radiation efficiency and highly directional resonant antenna. Good impedance matching is achieved at the resonating frequencies with 5.6% bandwidth. The radiation characteristics including radiation efficiency and absorption cross section show significant improve on account of using PBG crystals substrate for graphene based patch antenna. The simulation has been performed using High Frequency Simulator Software (HFSS), which is a commercially available electromagnetic simulator based on finite element method technique.

A number of improvements in WLAN leads to the deployment of Wireless Sensor Networks. Generally, WS N is a collection of a number of sensor nodes. Because it is very easy to deploy these sensor nodes so WS N gets popularity very quickly. The main applications of WSN are rescue mission & monitoring the temperature of environment etc. But as WSN has open access so security is very important. A number of security methods are there like WEP, WPA and 802.11i. In Feb. 2014 a protocol named as FLAP was proposed as an efficient and fast authentication protocol. Various nodes in WSN communicate to one another with the help of routing protocols like AODV & DS DV. But the Delay Time due to authentication process in these routing protocols is very high. We used FLAP protocol with DSDV protocol in WSN for the fast authentication purpose and compared its results with DSDV using 802.11i for authentication. The simulation results taken through NS 3 shows that FLAP has better performance as compare to 802.11i security method with DSDV. Comparison has done on the basis of throughput & delay time parameters.

This paper investigates the application of tilt integral derivative (TID) control as a supplementary controller for two-area thermal-thermal systems. The purpose of using TID control in AGC systems is to propose an improved feedback loop compensator, which possesses the merits of conventional PID control and offers better and optimal response. The paper utilizes the integral square error (ISE) performance index to form an objective function and a constrained non-linear minimization (CNM) optimization technique for evaluating the objective function. Hence, optimal values of controller parameters are obtained which offers a favorable operating condition for the system. A comparison of dynamic response of AGC systems with proposed TID control and PID control approach reveals that proposed TID controller is capable of delivering better performance.

CDMA implementation is widely used in various communication systems because of its high spectral efficiency. But near- far interference proves to be a serious problem tending to reduce the performance of CDMA systems. This problem can be reduced by implementing adaptive power control techniques. In this research paper, fuzzy logic based closed loop adaptive power control has been proposed for minimization of near-far interference. A fuzzy inference system has been developed which gives power control information on the basis of Received Signal Strength Indicator (RSSI), Signal to Noise Ratio (SNR), distance between base station and mobile station and degree of obstacles occurred in communication path. The results reveal that Fuzzy logic based closed loop adaptive power control system minimizes the near-far interference and improves the performance of CDMA systems in terms of spectral efficiency and system capacity.

Free Space Optics (FSO) has gained significant importance for high bandwidth transmission capabilities in recent years. However, various factors contribute to considerable link performance degradation. In this paper, the most crucial weather phenomenon, i.e., fog, is taken into account as it severely affects the performance of the link. One of the most promising methods to mitigate impairments of the performance of FSO systems in such weather conditions is to choose the most suitable amplifier along with the use of array of receivers. This paper analyses and compares the performance of the link for different amplifiers in order to achieve reliable performance of link in heavy fog conditions. The model is simulated and the important simulation parameters that are bit error rate (BER), height of eye diagram, received signal power and Quality factor are discussed using different number of photo detectors in FSO link.

This paper demonstrates the excellent temperature sensing property of the Graphene Nano-ribbon (GNR). The GNR junction used is of zigzag- armchair-zigzag configuration. The zigzag portion used is metallic in nature and the central region (armchair type) is semiconducting in nature. It is observed that with the increase in temperature from -273°C to 227°C, the conductance of the used sample follows a pattern which is linear in nature. This linear range of the pattern is being used for making the temperature nano-sensor. The range of the temperature is such chosen that it could be utilized for the various medical and industrial based applications. The results show that the temperature nano-sensor has a high resolution of 11095 Ω/°C, large temperature coefficient of resistance (TCR) 6.01 × 10-3°C-1 and wide temperature range -273.15°C to 227 °C.

In this paper, a design and implementation of single-band E-shaped Microstrip patch antenna for IEEE 802.11b (2.38GHz ~ 2.455 GHz) frequency band represented. An E-shaped patch antenna with substrate thickness of h=2mm, relative permittivity of dielectric substrate is 2.55 and resonate at resonance frequency of fr = 2.4 GHz for Bluetooth applications is designed and simulated successfully [2-3]. The design and simulation of antenna is performed by IE3D (Method of Moment) based full wave electromagnetic simulator. After that, now the same antenna is modelled and analysed using different Artificial Neural Network (ANN) models for parameters estimation having `Translm' function based Multilayer Perceptron (MLP) and Radial Basis Function (RBF) model. An ANN used for analysis is firstly trained by using data set obtained from electromagnetic simulator of antenna using IE3D software. This model has two input parameters: x-coordinate and y- coordinate of probe feed point and has four output parameters: Resonant Frequency(fr) Return Loss (S11 parameter), VSWR (dB) and Input Impedance (Rin in ohm).
