Abstract
| Pages: 58-65
Intensity-Duration-Frequency (IDF) relationship of rainfall amount is one of the most commonly used tools in water recourses engineering. The IDF relationships are used as an aid when designing drainage works for any engineering project, and allow the engineer to design safe and economical flood control measures. The main objective of this paper is to develop the rainfall intensity-duration-frequency relationships (IDF) curves and to derive a relationship between intensities and durations for a number of recurrence intervals through regression of generated IDF curves for Abha city in the Kingdom of Saudi Arabia. These curves have been generated from a 34-year recorded rainfall data for Abah region. Different frequency analysis techniques have been used to develop the relationship from rainfall data between the rainfall intensity, storm duration, and return periods from rainfall data for Abha region. These techniques are: Gumble, Log normal and Log Pearson Type III distribution. In order to do that, good record of the rainfall data was obtained for different durations. These methods were used to obtain the IDF curves for eight different durations (10, 20, 30, 60, 120, 180, 360, 720 mints) and six frequency periods (2, 5, 10, 25, 50, 100 years). It was shown that there were small differences between the results obtained from the three methods. Rainfall intensities obtained from three methods showed good agreement of the study area. Derived equations for calculating rainfall intensity for Abha region was obtained using three techniques based on the results obtained from IDF data. Estimation of the parameters of the IDF equations for different return periods was performed by using linear regression analysis. One of the goodness-of-fit tests (chi-square test) was used to choose the best statistical distribution among them.

Globally the healthcare sector is abundant with data and hence using data mining techniques in this area seems promising. Healthcare sector collects huge amounts of data on a daily basis. Transferring data into secure electronic system of medical health can save lives and reduce the cost of healthcare services as well as early discovery of contagious diseases with advanced collection of medical data. In this study we have proposed a best fit for data mining techniques in healthcare based on a case study. The proposed framework aims to provide self healthcare treatments where by several monitoring equipments using the cyberspace devices have been developed to help patients manage their medical conditions at home for example, diabetic patients can test their blood sugar level by using e-device, which ,with the click of a computer mouse, downloads the results to a healthcare practitioner, minimizes time to wait for medical treatments, and minimizes the delay time in providing medical treatments. Data mining is a new technology used in different types of sectors to improve the effectiveness and efficiency of business model as well as solving problems in business world.

Abstract
| Pages: 13-17
The objective of this present work is to estimate the deflection, stress and mode frequency induced in the leaf spring. The component chosen for analysis is a leaf spring which is an automotive component used to absorb vibrations induced during the motion of vehicle. It also acts as a structure to support vertical loading due to the weight of the vehicle and payload. Under operating conditions, the behaviour of the leaf spring complicated due to its clamping effects and interleaf contact, hence its analysis is essential to predict the displacement, mode frequency and stresses. The leaf spring, which we are analyzing, is a custom designed leaf spring with different eyes like viz., Berlin and upturned eyes with different materials at different sections. In analysis part the finite element of leaf spring is modelled. Appropriate boundary conditions, material properties and loads are applied selected as per intended performance. The resultant deformation, mode frequencies and stresses obtained are analyzed.

Abstract
| Pages: 18-26
A continuous mathematical model of salmonella diarrhea is introduced in this paper. According to the pathogenesis of salmonella, the model had been designed as an SIRS system comprising of a non-constant population. The disease-free state and the basic reproduction number (R0) have been computed for this system. In epidemics, there are always two cases: R0 < 1 (disease-free state) and R0 > 1 (epidemic existing state). Simulations of the system have been presented for both these cases which show the variations of the population in different situations. Data that has been used for examples and simulations is based on the demographics and disease outbreaks in Botswana.

Abstract
| Pages: 27-30
With the increasing use of high-speed Internet technologies during the past few years, the concept of cloud computing has become more popular. Especially in this economy, cloud services can provide speed, efficiencies and cost savings. In cloud computing, users work with Web-based, rather than local, storage and software. These applications are accessible via a browser and look and act like desktop programs. With this approach, users can work with their applications from multiple computers. In addition, organizations can more easily control corporate data and reduce malware infections. Now, a growing number of organizations are adding to the cloud concept by releasing commercial and open source Web-based operating systems. This paper deals with how Web OS uses cloud computing concept. The Web OS goes beyond basic desktop functionality. It also includes many of a traditional OS’s capabilities, including a file system, file management, and productivity and communications applications. In the case with Web-based applications, the Web OS functions across platforms from any device with Internet access. The Web OSs that run on the browser are platform-independent, since browsers are built to work across different operating systems. As users become more comfortable working over the Web, the Web OS could become more popular

Abstract
| Pages: 39-46
In the applications like medical radiography enhancing movie features and observing the planets it is necessary to enhance the contrast and sharpness of an image. We propose a generalized unsharp masking algorithm using the exploratory data model as a unified framework. The proposed algorithm is designed to address three issues:1) simultaneously enhancing contrast and sharpness by means of individual treatment of the model component and the residual,2)reducing the halo effect by means of an edge-preserving filter, and 3)solving the out of range problem by means of log ratio and tangent operations. We present a new system called the tangent system which is based upon a specific bregman divergence. Experimental results show that the proposed algorithm is able to significantly improve the contrast and sharpness of an image. Using this algorithm user can adjust the two parameters the contrast and sharpness to have desired output.

Modelling the rip current flow on a quadratic beach profile

Abstract
| Pages: 47-62
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 wave-averaging 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.
