Advancement in VANET Routing by Optimize the Centrality with ANT Colony Approach
Monika Thakur || Saurabh Sharma
India
Paper Indexed : : 03.3005/xxxxxxx
International Journal of Computational Engineering Resaerch, Volume 06 ~ Issue 12 (December 2016)

Abstract

In a wireless ad hoc network, an opportunistic routing strategy is a strategy where there is no predefined rule for choosing the next node to destination (as it is the case in conventional schemes such as OLSR, DSR or even Geo-Routing). A popular example of opportunistic routing is the "delay tolerant" forwarding to VANET network when a direct path to destination does not exist. Conventional routing in this case would just "drop" the packet......

Abstract

The sun is the primary source of energy. The sun, which is the largest member of the solar system,is a sphere of intensely hot gaseous matter having a diameter of 1.30 x 109 m, and at an average distance 1.495 x 1011 from the earth. An definite knowledge of the solar radiation distribution at a particular geographical location is of huge importance for the progress and development of many solar energy devices and for estimates of their performance as well as install new solar power plant. In this study, the measured or estimate data of global solar radiation on a horizontal surface and number of Bright Sunshine Hours (BSH) for Gujarat was analyzed of different locations. The solar energy potential (BSH) of several locations in Gujarat is received by compiling data from Agricultural Universities,Anand, S.K.Nagar, Navsari and Junagadh.......

Paper Indexed : : 03.3005/xxxxxxx
International Journal of Computational Engineering Resaerch, Volume 06 ~ Issue 12 (December 2016)

Abstract

With the increasing amount of Arabic text on the web and in the information repositories and the demand of users to have specific answers to their questions, the need for Question Answering (QA) Systems became a necessity. Our Question Answering System answers two types of Questions: How and Why Questions. The system takes a question given in natural language expressed in the Arabic language and attempts to produce concise answers. The system's main source of knowledge is a collection of Arabic text documents extracted from the Arabic Wikipedia. The reasons behind developing this system is due to the absence of Arabic Questions Answering Systems(QASs) which deals with How and Why questions and this is because of the complexity of extracting the answers......

Paper Indexed : : 03.3005/xxxxxxx
International Journal of Computational Engineering Resaerch, Volume 06 ~ Issue 12 (December 2016)

Abstract

The discrete model used is an N-Degree of Freedom system made of N masses placed at the ends of solid bars connected by springs, presenting the beam flexural rigidity. The large transverse displacements of the bar ends induce a variation in their lengths giving rise to axial forces modelled by longitudinal springs causing nonlinearity. Nonlinear vibrations of clamped beam carrying n masses at various locations are examined in a unified manner. A method based on Hamilton's principle and spectral analysis has been applied recently to nonlinear transverse vibrations of discrete clamped beam, leading to calculation of the nonlinear frequencies. After solution of the corresponding linear problem and determination of the linear eigen vectors and eigen values, a change of basis, from the initial basis, i.e.......

'O' Model for Component-Based Software Development Process

Paper Indexed : : 03.3005/xxxxxxx
International Journal of Computational Engineering Resaerch, Volume 06 ~ Issue 12 (December 2016)

Abstract

The technology advancement has forced the user to become more dependent on information technology, and so on software. Software provides the platform for implementation of information technology. Component Based Software Engineering (CBSE) is adopted by software community to counter challenges thrown by fast growing demand of heavy and complex software systems. One of the essential reasons behind adopting CBSE for software development is the fast development of complicated software systems within well-defined boundaries of time and budget. CBSE provides the mechanical facilities by assembling already existing reusable components out of autonomously developed pieces of the software. The paper proposes a novel CBSE model named as O model, keeping an eye on the available CBSE lifecycle.

International Journal of Computational Engineering Resaerch, Volume 06 ~ Issue 12 (December 2016)

Abstract

This paper presents a longitudinal control algorithm for a smart cruise control with virtual parameters in multiple transitions by a driver and traffic conditions. The object is to achieve driver's comfort and smooth transition with collision prevention for safety in various driving situations. The proposed algorithm consists of an in-path target selection, a generation of virtual parameters, and longitudinal controller for smart cruise control. The in-path target selection algorithm selects an important target which moves on the driving direction of subject vehicle. In addition, it provides the information in order to drive a subject vehicle smoothly and improve safety in various traffic transitions. Finally, smart cruise control controller with virtual parameters computes the desired acceleration........

Abstract

This paper describes the design, building and testing of a Drone Flight Navigation (DFN) system used to control the movement of livestock away from the ploughing fields. The inputs to the DFN system include different sounds of livestock to be removed from the fields. The output of the system will be the irritating sounds to the livestock and also deploy a rotating umbrella-like cloth and flashing LED lights to scare the animals even more. The input and output sounds are stored in a database and can be updated with preferred sounds. We have successfully simulated and programmed a prototype DFN system using ALTERA UP1 Development Board. Also on this paper, we discussed drone power management system (DPMS) which ensures that the drone has enough battery power before each flight. For future developments, GPS and video camera capabilities can also be included into the design so that the farmer will be able to observe what the system is seeing and possibly give live instructions.

Alternative and Explicit Derivation of the Lattice Boltzmann Equation for the Unsteady Incompressible Navier-Stokes Equation
John Ryan Murdock || Song-Lin Yang
USA
Paper Indexed : : 03.3005/xxxxxxx
International Journal of Computational Engineering Resaerch, Volume 06 ~ Issue 12 (December 2016)

Abstract

A lattice Boltzmann equation for fully incompressible flows is derived through the utilization of appropriate ansatzes. The result is a singular equilibrium distribution function which clarifies the algorithm for general implementation, and ensures correct steady and unsteady behavior. Through the Chapman-Enskog expansion, the exact incompressible Navier-Stokes equations are recovered. With 2D and 3D canonical numerical simulations, the application, accuracy, and workable boundary conditions are shown. Several unique benefits over the standard equation and alternative forms presented in literature are found, including faster convergence rate and greater stability

Paper Indexed : : 03.3005/xxxxxxx
International Journal of Computational Engineering Resaerch, Volume 06 ~ Issue 12 (December 2016)

Abstract

Sybil attack can counterfeit the traffic scenario by sending false messages with multiple identities, which often causes a traffc jam and even leads to vehicular accidents in vehicular ad-hoc network (VANET). It is very difficult to be defended and detected, especially when it is launched by some conspired attackers using their legitimate identitiess. Since few years, Vehicular Ad hoc Networks deserve much attention. VANET technology uses moving cars as nodes in network to create a mobile network it turns every participating car into a wireless router or nodes, allowing cars approximately hundred to three hundred meters of each other to connect and in turn, create a network with a wide range........
