An Expert System For Diagnosing Eye Diseases Using Clips

Abstract: This work presents the design of an expert system that aims to provide the patient with background for suitable diagnosis of some of the eye diseases. The eye has always been viewed as a tunnel to the inner workings of the body. There are many disease states that may produce symptoms from the eye. CLIPS language is used as a tool for designing our expert system. An initial evaluation of the expert system was carried out and a positive feedback was received from the users.

An image encryption approach using chaos and stream cipher

Abstract: In this paper, a novel image encryption scheme is proposed based on combination of pixel shuffling and W7. Due to sensitivity to initial conditions, chaotic maps have a good potential for designing dynamic permutation map. So a chaotic Henon map is used to generate permutation matrix. An external secret key is used to derive the initial conditions for the chaotic map and W7 secret key. Pixel shuffling is performed via vertical and horizontal permutation. Shuffling is used to expand diffusion in the image and dissipate the high correlation among image pixels. In order to evaluate performance, the proposed algorithm was measured through a series of tests. Experimental results illustrate that the scheme is highly key sensitive and shows a good resistance against brute-force and statistical attacks.

A review on abstractive summarization methods

Abstract: Text summarization is the process of extracting sal ient information from the source text and to presen t that information to the user in the form of summary. It is very difficult for human beings to manually summarize large documents of text . Automatic abstractive summarization provides the r equired solution but it is a challenging task because it requires de eper analysis of text. In this paper, a survey on a bstractive text summarization methods has been presented. Abstractive summarization methods are classified into t wo categories i.e. structured based approach and seman tic based approach. The main idea behind these methods has been discussed. Besides the main idea, the strengths and weaknesses of each method have al so been highlighted. Some open research issues in abst ractive summarization have been identified and will address for future research. Finally, it is conclud ed from the literature studies that most of the a bstractive summarization methods produces highly coherent, cohesive, information rich and less redundant summary.

A survey of copy-move forgery detection techniques

Abstract: Copy-Move forgery is one of the significant image manipulations, where some image parts are copied and pasted in original image. In this survey, we firstly review about digital image forensics and its types. The brief discussion about current research presented here with an analysis of the existing approaches for detect image tampering, which are classified into block-based method and key point-based method. Then we demonstrate the popular techniques of two methods and analysis of several techniques. Finally, the all techniques advantages and disadvantages summarized and some future research directions were pointed out.

The success of learning management system among distance learners in Malaysian universities

Abstract: Continuing formal education is essential for distance learners to improve their learning skills and knowledge to meet the challenge career in modern competitive world. This study examines the success factors that influence learners' use of the Learning Management System (LMS) and tests the applicability of the propose model, in the context of distance learning practices in higher education. A survey was conducted to higher education learners who involved in distance learning instruction. This study used a set of questionnaire which was adapted from the literatures to examine three groups of dimensions, system design (system quality, service quality, information quality, usefulness and ease of use), system usage (system use, behavioural intention to use and user satisfaction) and System Outcome (net benefit). Using data from a survey to distance learning students (N=425), a path analysis revealed that system design has a significant influence on user satisfaction and intention to use of the LMS which directly affect the use of the system. Consequently user satisfaction and system used show strong impact to the net benefit.
