An Analytical Model Of The Rip Current Flow

Dr. Evans F. Osaisai

Abstract

In this paper we develop an analytical theory for the interaction between waves and currents induced by breaking waves on time-scales longer than the individual waves. We employed the waveaveraging procedure that is commonly used in the literature. The near-shore zone is often characterized by the presence of breaking waves. Hence we develop equations to be used outside the surf zone, based on small-amplitude wave theory, and another set of equations to be used inside the surf zone, based on an empirical representation of breaking waves. Suitable matching conditions are applied at the boundary between the offshore shoaling zone and the near-shore surf zone. Essentially we derive a model for the interaction between waves and currents. Both sets of equation are obtained by averaging the basic equations over the wave phase. Thus the analytical solution constructed is a free vortex defined in both shoaling and surf zones. The surf zone solution is perturbed by a longshore component of the current. Thus the presence of the rip current cell combined with the longshore modulation in the wave forcing can drive longshore currents along the beach. The outcome, for our set of typical beach profile, is a description of rip currents.

Keywords: Wave-current interactions, surf zone, shoaling zone, matching conditions, waveaveraging, rip currents, radiation stress.

A Novel Marker Based Interactive Image Segmentation Method

K Vani Sree , A Vanaja

Abstract

An important branch of computer vision is image segmentation. Image segmentation aims at extracting meaningful objects lying in images either by dividing images into contiguous semantic regions, or by extracting one or more specific objects in images such as medical structures. The image segmentation task is in general very difficult to achieve since natural images are diverse, complex and the way we perceive them vary according to individuals.For more than a decade, a promising mathematical framework, based on variational models and partial differential equations, have been investigated to solve the image segmentation problem. The proposed scheme is simple yet powerful and it is image content adaptive. With the similarity based merging rule, a two stage iterative merging algorithm was presented to gradually label each non-marker region as either object or background.We implementened the MSRM algorithm in the MATLAB.

Design of low power fir filter technique with booth multiplier and delay buffer

Gummadi.Lakshmi Pratap ,P.suresh

Abstract

This paper presents the methods to reduce dynamic power consumption of a digital Finite Imppulse Respanse (FIR)filter these methods include low power serial adder, combinational booth multiplier And low-powerdelay buffer. The proposed delay buffer uses several new techniquesto reduce its power consumption. Since delay buffers are accessed sequentially, it adopts a ring-counter addressing scheme. In the ring counter, double-edge-triggered (DET) flip-flops are utilized to reduce the operating frequency by half and the C-element gated-clock strategy is proposed. A novel gated-clock-drivertree is then applied to further reduce the activity along the clock distribution network. Moreover, the gated-driver-tree idea is also employed in the input and output ports of the memory block to decrease their loading, thus saving even more power. folding transformation in linear pheasarchitecture and applied to firfilters to power consumption reduced thus reduce power consumption due to glitching Is also reduced. The proposed FIR filters were synthesized implemented using Xilinx ISE Virtex IVFPGA and power is analized using Xilinx XPower analyzer.

Computational Analysis and Design for Precision Forging Of Aluminium AA 6061 Connector

Santhosh.N , Vinayaka.N , Dr.Aswatha , Uday.M , Praveena.B.A

Abstract

Development of a new process methodology which satisfies given criteria is a big challenge faced by most of the forging industries. The domain of competition is quite large and hence every firm aims at producing near net shapes thereby eliminating the need for machining and other secondary operations. The present investigation deals with the flow simulation of Aluminium forgings conforming to AA 6061 specification and henceforth studies the mechanical characteristics of the flow simulation results. The Aluminium AA 6061 component considered is precision forged with a hydraulic press in a die having geometrical interlocking. During precision forging it was difficult to achieve the required net shape of the component because of unsymmetrical location of small ribs on cylindrical surface and variation in the cross sections from bottom to top (i.e. unsymmetrical about both X & Y axis). Thus to eradicate the problem encountered, the flow simulation of the precision forging process was carried out and the mechanical characteristics of the flow simulation results obtained were studied

Steady And Unsteady Bubbly Two-Phase Flow (Gas-Liquid Flow) Around A Hydrofoil In Enlarging Rectangular Channel

Laith Jaafer Habeeb,Riyadh S. Al-Turaihi

Abstract

Experimental and numerical studies are investigated to study the two-phase flow phenomena around straight hydrofoil for different angle of attacks in a rectangular enlarging channel which has the dimensions (10  3  70 cm) enlarged from assembly circular tube of the two phases. Experiments are carried out in the channel with air-water flow with different air and water flow rates. These experiments are aimed to visualize the two phase flow phenomena as well as to study the effect of pressure difference through the channel with the existence of the hydrofoil. All sets of the experimental data in this study are obtained by using a pressure transducer and visualized by a video camera for different water discharges (20, 25, 35 and 45 l/min), different air discharges (10, 20, 30 and 40 l/min) and different angle of attack (0, 15 and 30 degree). While the numerical simulation is conducted by using commercial Fluent CFD software to investigate the steady and unsteady turbulent two dimensional flows for different air and water velocities. The results show that when the angle of attack increases at constant air and water discharge or when air discharge increases with constant water discharge and angle of attack or when water discharge increases with constant air discharge and angle of attack, the pressure difference increases at the inlet and the outlet of the rectangular channel.

Cominga Well-Organized Hiding System And Constancy Conservation In Mixture P2P System

N. Manjula, R.V. SubbaRayudu, K. Niharika, G.Prathap

Abstract

Peer-to-peer overlay networks are widely used in distributed systems. P2P is a popular technology used for file sharing. File replication and Consistency maintenance are the techniques used in P2P for high system performance. The objective of this work is to design a hybrid peer-to-peer system for distributed data sharing which combines the advantages of both types of peer-to-peer networks and minimizes their disadvantages. However, in peer-to-peer networks, Information Retrieval (IR) performance is determined by both technology and user behavior, and little attention has been paid in the literature to improving IR performance through incentives to change user behavior.The proposed hybrid peer-to-peer system is composed oftwo parts: the first part is a structured core network the second part is multiple unstructured peer-to-peer networks each of which is attached to a node in the core network.Our cachingscheme can deliver lower query delay, better load balance and higher cache hit ratios.

R. Jansi Rani, S.Jyothirmayee, M.Sushanth, M.Ravi Prakash

Abstract

ATM - originally designed for WAN communications, but quickly adapted for LANs as well, ends this historical separation and forms a universal platform for data communication, In both ATM LAN AND ATM WAN networks the data transport is achieved via connection-oriented communication paths, which are set up though high-speed switching systems. These ATM switches perform the cell routing from the input ports of the switch to the destination port in real time and in parallel for the ports. ATM can handle all of today's data services (telephone, data, video-broadcast and interactive) in an efficient way ATMs have become very popular with the general public for their availability and general user friendliness. ATMs are now found in many locations having a regular or high volume of consumer traffic. For example, ATMs are typically found in restaurants, supermarkets, Convenience stores, malls, schools, gas stations, hotels, work locations, banking centers, airports, entertainment establishments, transportation facilities and a myriad of other locations. ATMs are typically available to consumers on a continuous basis such that consumers have the ability to carryout their ATM financial transactions and/or banking functions at any time of the day and on any day of the week.

Detection and Prevantion of Black Hole Attack over Manet

Raghvendra Prasad

Abstract

The black hole attack is one of the well-known security threats in wireless mobile ad hoc networks. The intruders utilize the loophole to carry out their malicious behaviors because the route discovery process is necessary and inevitable. Many researchers have conducted different detection techniques to propose different types of detection schemes. In this paper, we survey the existing solutions and discuss the state-of-the-art routing methods. We not only classify these proposals into single black hole attack and collaborative black hole attack but also analyze the categories of these solutions and provide a comparison table. We expect to furnish more researchers with a detailed work in anticipation.

Power Line Communications

Abdelraheem Mohamed Elkhalifa, Dr. Abdul rasoul J. Alzubaidi

Abstract

This paper is about power-line communication over the low-voltage grid, which has interested several researchers and utilities during the last decade, trying to achieve higher bit-rates and more reliable communication over the power lines.The main advantage with power –line communication is the use of an existing infrastructure. Wires exist to every household connected to the power – line network.This paper starts with a general introduction to power-line communication. Then an existing application, communicating on a low voltage grid is investigated in order to obtain some knowledge of how the power line acts as a communication channel. I did experiment to verify that result.The power line communication channel can in general be modeled as a system with frequency dependent signal-to-noise ratio varying with time over the communication bandwidth. Finally we describe the basic parts of the system that eventually could be used for information transfer over the power line communication channel

Improvement of Pv Systems Power Output Using Sun-Tracking Techniques

B. O. Anyaka, D. C. Ahiabuike , M. J. Mbunwe

Abstract

The amount of power produced by a photovoltaic (PV) or solar panel depends on the amount of sunlight to which it is exposed. As the sun's position changes throughout the day, the PV panel must be adjusted so that it is always aimed directly at the sun and, as a result, produces the maximum possible power. A sun-tracking system tracks the motion of the sun across the sky and moves the PV panel to face directly at the sun and thereby ensuring that maximum amount of sunlight strikes the panel throughout the day. Sun-tracked PV systems are more efficient than fixed PV systems and are capable of enhancing productivity. In this paper different types of sun-tracking systems are reviewed and their energy gains are discussed

Prediction of Voltage Instability in Nigeria Interconnected Electric Power System Using V-Q Sensitivity Method

Enemuoh F. O., Madueme T. C., Onuegbu J. C., Anazia A. E

Abstract

The need to predict power system stability as it concerns voltage status is very important for the system planning, operation and control. This paper presents the prediction of voltage instability in Nigerian interconnected electric power system using V-Q sensitivity method. The method makes use of the least eigenvalue of the Jacobian matrix of the power system to calculate the V-Q sensitivity of the system. The highest sensitivity is an indication of the bus prone to voltage instability. The result from our calculations showed that Nigerian power system has the highest V-Q sensitivity of 0.1474 at the Maiduguri bus followed by Gombe, Kano and Jos with 0.1312, 0.0823 and 0.0370 respectively. It is very clear that the first bus that will collapse on the same percentage of loading will be Maiduguri followed by Gombe then Kano and Jos.

Analysis of the Hurst Exponent for M2M Applications

Stephen P. Emmons, Farhad Kamangar 

Abstract

Machine-to-Machine (M2M) applications represent a class of systems that make significant demands on the global Internet infrastructure. It is important to understand and characterize the behavior of these systems so that they may be effectively engineered for scalability and reliability. This paper analyzes the "Hurst exponent" (H) for several M2M applications of varying sizes with data collected for up to six months. The Hurst exponent is a measure of the long-term dependence and self-similarity typical of Internet-based communications systems. The analysis focuses specifically on the use of the "Rescaled-Range Statistic" (R/S), and also includes several other methods for comparison, including "Absolute Moment," "Aggregate Variance," "Higuchi," and "Residuals of Regression." The results show that such applications indeed exhibit strong long-term dependence, consistent with results found for other Internet communications studies.

Abstract

Ecologists Have Observed That, In A Harsh Environment, Plant Species May Cease To Compete For Resources, But Display Positive Interactions Such As Mutualism. This Means That The Impact Of Climate Change, Where Harsh Envi- Ronments May Become More Benign, Could Be To Change The Nature Of Interac- Tions Between Plant Species And This May Be One Influence On Biodiversity. In This Talk, We Have Considered Whether The Observed Positive Interactions May Be Explained Through A Combination Of Existing Models Of Competition With Other Known Features Of The Environment In The Arctic (Where These Observa- Tions Have Been Made). This Provides A Prototype Model Where Sensitivity Of The Ecosystem To Different Types Of Environmental Change May Be Considered.

Pedagogical Engineering to Develop Digital Fluency Among Pre-Service Teachers and Educational Leaders Of The 21st-Century

Dr Charles Kivunja

Abstract

The children in our classrooms today have advanced skills for texting their friends on their eTablets and cell phones, instant messaging chats to their peers, dialoguing on MySpace, Twitter or Facebook, surfing the web or playing Xbox or Wii games. These Y Gen, Net Gen, Millennials and Z Gen, Digital Natives, are the children of the digital generation. Unfortunately, most of the teachers in today's classrooms belong to the pre-digital generation and are immigrants without the skills required for 21st century digital fluency. Moreover, their classrooms are not engineered for a digital pedagogy. This has created a teacher-student-classroom mismatch, which at worst, is characterized by the tragedy of illiterate teachers teaching literate students and by the dilemma of teachers who find the present tense and the past perfect! Pedagogical engineering is urgently needed to develop the digital fluency of teachers so they can speak their students' language. One way to achieve this is to engineer digital technologies into curriculum as discussed in this paper which reports the results of classroom trials conducted with over 400 undergraduate and 15 doctoral students by the author, in the last three years. The paper concludes that there is an urgent need to train pre-service teachers and educational leaders in digital fluency. Failure to do so will perpetuate the mismatch between digital savvy students and teachers stuck in the orthodoxy pedagogy of the last century.
