Abstract:

Grid stations get generated power from power stations that are ordinarily far; continuous consumption or use of electric power has expanded in most recent couple of years. Transmission system is the system by methods for which power is transmitted from place of generation to the consumers. Overhead wires or conductors are the medium used for transmission of power. These wires are visible to wind, heat and ice. The efficiency of the power system increases if the losses of these overhead wires are minimal. These losses are based on the resistive, magnetic and capacitive nature of the conductor. It is necessary to create or make proper design of these conductors accompanied by proper installation. To balance the working and strength of overhead transmission line and to minimize its capacitive effect the conductors must be installed in catenary shape. The sag is required in transmission line for conductor suspension. The conductors are appended between two overhead towers with ideal estimation of sag. It is because of keeping conductor safety from inordinate tension. To permit safe tension in the conductor, conductors are not completely extended; rather they are allowed to have sag. For equal level supports this paper provides sag and tension estimation with two different cases under maximum operating temperature 45 °C. To calculate sag-tension estimation of ACSR (Aluminum Conductor Steel Reinforced) overhead lines twoe different cases are provided with no and high wind speed effects. Four different span lengths are taken for same level supports. ETAP (Electrical Transient and Analysis Program) is used for simulation setup. The results shows that wind effect has great impact upon line tension and with addition of wind speed the sag of line remains same while tension altered.

Abstract:

As beam steering antennas are being an ideal solution for many satellite applications, this paper is concerned on the design of a 16-element linear array antenna, using an RT Duroid substrate at 20.2 GHz for Ka-Band satellite communications. The design is initiated with single element and thereby incremented in steps to 2, 4, 8 and 16 elements. An optimum inter element spacing of 0.73λ is considered for the purpose of fulfilling the desired scanning requirement. Performance analysis of the proposed antenna is analyzed mainly in terms of Relative Side Lobe level (RSLL) and Beam steering. To synthesize the antenna, weights of the antenna are considered according to Taylor’s amplitude distribution along the antenna aperture to attain a relative side lobe level of -25dB. The proposed 16-element linear array antenna achieved a maximum gain of 19.5dB and the main beam direction can be switched up to 50o (±25o) without introduction any grating lobes. In addition to, other relevant antenna parameters such as reflection coefficient, VSWR, gain and efficiency of single, 2, 4, 8 and 16 element antennas are compared. The proposed linear array antenna is designed using Ansoft HFSS.

In this paper, we explore the existence and uniqueness of positive solutions for the following nonlinear fourth order ordinary differential equation        (4) u t  f t,u t , t a, b , withthe following arbitrary two-point boundary conditions: ua  ub  ua  ub  0, where, a, b are two arbitrary constants satisfying b  0, a 1 b and f Ca,b0,,0,.Here we also demonstrate that under certain assumptions the above boundary value problem exist a unique symmetric positive solution. The analysis of this paper is based on a fixed point theorem in partially ordered metric spaces due to Amini-Harandi and Emami. The results of this paper generalize the results of several authors in literature. Finally, we provide some illustrative examples to support our analytic proof.

Abstract:

In the present internet world, Security is a prime vital concern and the secure hash function is one of the ideal alternative means to guarantee security. In this paper we made a study on different nonlinear dynamical systems – Chaotic maps and introduced a novel hash scheme based on integrated chaotic maps. The experimental outcomes shows that the proposed model satisfies all cryptographic properties of secure hash functions such as resistant to collisions, high level of sensitivity to initial conditions, high confusion and diffusion, high randomization etc. The suggested model is fast and accurate in terms of speed and security is concern. In this model, multiple chaotic maps are integrated as a single chaotic system to generate an n-bit digest value, where the length of digest is flexible in terms of security is concern.

Abstract:

Portable water is a gift of God, which is used by human beings both for domestic and industrial purposes, but when it is polluted by certain reasons it become useless and adversely effects human health, aquatic life and threats the ground water. There are many sources of water pollution and Industrial pollution is one major source and concern for today’s world because toxic substances and chemicals used as raw products in industries is being discharged as residual to the water bodies if not treated. The HIE is no exception, where different industries are indiscriminately releasing their untreated effluents to open nallah, which ultimately makes its way into river Kabul while passing through urban and rural areas of Peshawar. The river Kabul water is widely used for irrigation purposes and is affecting the human and marine life because of the untreated toxic effluents. The study deals with the estimation and characterization of pollutions load discharged by the HIE and possible solutions to control these effluents at source i.e. at individual industrial level or at a Combined Effluent Treatment Plant (CETP). The study concluded that toxic effluents with high BOD, COD and TSS along with number of other heavy metals are released untreated. These effluents cannot be treated at source due to high cost and non-availability of land in existing developed industries. Also it is not advisable to install individual treatment plants due to lack of technical knowhow and high maintenance costs. The solution for this is to install a CETP at a suitable location on common benefit and maintenance cost mechanism.

Abstract:

Nanotechnology has enticed a good attention in boosting base fluid such as crude oil. A mathematical model is investigated to study MHD Carreau crude oil based nanofluids. Analysis over stretching sheet surface is illustrated that include consideration of nanoparticles shape with high (E1=5.0) and low (E1=0.0) electric field. Depending on nanoparticle shape, deferent expects of nanofluids flow such that the shapes as (sphere, cylinder, lamina) to boost the heat and mass transfer. Employing convenient self-similar transformation, the set of partial differential equation converted to dimensionless system. These equations has numerically solution by apply Runge-Kutta Fehlberg form plus so-called shooting technique and solving algebraically in Maple 18. Effect of relevant parameters on all concerned profile are incurred to examine the heat and mass transfer properties. For thermal radiation and heat generation parameters the profiles are on negative worth of temperature, is seen in the out of boundary region all these physical behaviours are due to the combined effects of the viscosity and density of the crude oil. The result obtained that heat generation, Brownian motion and magnetic field hit a dominant role on  Al<sub>2</sub> O<sub>3</sub> Crude Oil. The investigation revealed that there is no important role for nanoparticle shapes on Al<sub>2</sub> O<sub>3</sub> Crude Oil.

Abstract:

In this article, we investigate the traveling wave solutions to the Klein-Gordon equation in (2+1)-dimension with special types of nonlinearity. The types include quadratic, cubic and polynomial nonlinearity. The Klein-Gordon equation assumes significant role in numerous types of scientific investigation such as in quantum field theory, nonlinear optics, nuclear physics, magnetic field etc. To investigate the aimed traveling wave solutions, we execute the (𝐺′/𝐺)-expansion method. The attained solutions are in the form of hyperbolic, trigonometric and rational functions. The results acknowledged that the applied method is very efficient and suitable for discovering differential equations with various types of nonlinearity considered in optics and quantum field theory. The solutions of the Klein-Gordon equation with quadratic, cubic, and polynomials nonlinearity play a significant role in many scientific measures notably optics and quantum field theory.

Abstract:

Wireless Body Area Sensor Network (WBANs) are used to measure the biological parameters of a human body in a critical health situation. Sensors use an antenna and electromagnetic radiations to drive the response towards the sink node. Our research focuses on the overheating problem of body tissues due to the electromagnetic field generated by electromagnetic radiations. When sensor nodes continuously send and receive the data, it not only influences the communication between the nodes by stimulating high attenuation for signal transmission, but also conduits various health problems. These health issues may include reducing blood flow, affecting the enzymatic reactions, brain tumor, damaging the sensitive tissues and leading to tissue cancer. The exposition of such issues are addressed in our research called iBTTA (Improved Body Tissue Temperature Aware)routing scheme, where not only the temperature of a body tissues is controlled under the threshold value but significantly improves the performance in terms of its throughput, end- to- end delay and transmission loss. The scheme is an extension of our previously published scheme BTTA. The validation of our scheme iBTTA is done through comparison with already existing techniques SIMPLE (Stable Increased-throughput Multi-hop Protocol for Link Efficiency in WBANs) and LAEEBA (Link-Aware and Energy Efficient scheme for WBANs). In iBTTA we have improved the problem of the body tissues temperature, utilization of battery power and load balancing techniques in WBANs.
