Paper 1: A New Approach for Arabic Handwritten Postal Addresses Recognition

Abstract: In this paper, we propose an automatic analysis system for the Arabic handwriting postal addresses recognition, by using the beta elliptical model. Our system is divided into different steps: analysis, pre-processing and classification. The first operation is the filtering of image. In the second, we remove the border print, stamps and graphics. After locating the address on the envelope, the address segmentation allows the extraction of postal code and city name separately. The pre-processing system and the modeling approach are based on two basic steps. The first step is the extraction of the temporal order in the image of the handwritten trajectory. The second step is based on the use of Beta-Elliptical model for the representation of handwritten script. The recognition system is based on Graph-matching algorithm. Our modeling and recognition approaches were validated by using the postal code and city names extracted from the Tunisian postal envelopes data. The recognition rate obtained is about 98%.

Paper 2: A Keyword Driven Framework for Testing Web Applications

Abstract: The goal of this paper is to explore the use of Keyword driven testing for automated testing of web application. In Keyword driven testing, the functionality of the system-under-test is documented in a table as well as in step by- step instructions for each test. It involves the creation of modular, reusable test components. These components are then assembled into test scripts. These components can be parameterized to make them reusable across various test script. These test scripts can also be divided into various reusable actions. This saves a lot of recording procedure. The Existing tools for this testing uses Html, Xml, Spreadsheet, etc. to maintain the test steps. The test results are analyzed to create test reports.

Paper 3: Effect of Error Packetization on the Quality of Streaming Video in Wireless Broadband Networks

Abstract: A Markov model describing the duration of error intervals and error-free reception for streaming video transmission was developed based on the experimental data obtained as a result of streaming video from a mobile source on IEEE 802.16 standard network. The analysis of experimental results shows that the average quality of video sequences when simulating Markov model of packetization of errors are similar to those obtained when simulating single packet errors with PER index in the range of 3×?10?^(-3) to 1×?10?^(-2). An algorithm for creating software for simulating packetization of errors was developed. In this paper we describe the algorithm, software developed based on this algorithm as well as the Markov model created for the modeling.

Paper 4: An Overview of Video Allocation Algorithms for Flash-based SSD Storage Systems

Abstract: Despite the fact that Solid State Disk (SSD) data storage media had offered a revolutionary property storages community, but the unavailability of a comprehensive allocation strategy in SSDs storage media, leads to consuming the available space, random writing processes, time-consuming reading processes, and system resources consumption. In order to overcome these challenges, an efficient allocation algorithm is a desirable option. In this paper, we had executed an intensive investigation on the SSD-based allocation algorithms that had been proposed by the knowledge community. An explanatory comparison had been made between these algorithms. We reviewed these algorithms in order to building advanced knowledge armature that would help in inventing new allocation algorithms for this type of storage media.

Paper 6: Contextual Modelling of Collaboration System

Abstract: Faced with new environmental constraints, firms decide to collaborate in collective entities and adopt new patterns of behavior. So, this firms’ collaboration becomes an unavoidable approach. Indeed, our aim interest in our study is to propose a collaborative information system for supply chain. Our proposed platform ensures cooperation and information sharing between partners in real time. In fact, several questions have to be asked: What is the information nature may be shared between partners? What processes are implemented between actors? What functional services are supported by the platform? In order to answer these questions, we present, in this article, our methodological approach of modelling, called CMCS (Contextual Modelling of Collaborative System).

Paper 9: Maximum-Bandwidth Node-Disjoint Paths

Abstract: This paper presents a new method for finding the node-disjoint paths with maximum combined bandwidth in communication networks. This problem is an NP-complete problem which can be optimally solved in exponential time using integer linear programming (ILP). The presented method uses a maximum-cost variant of Dijkstra algorithm and a virtual-node representation to obtain the maximum-bandwidth node-disjoint path. Through several simulations, we compare the performance of our method to a modern heuristic technique and to the ILP solution. We show that, in a polynomial execution time, our proposed method produces results that are almost identical to ILP in a significantly lower execution time.

Paper 10: Message Segmentation to Enhance the Security of LSB Image Steganography

Abstract: Classic Least Significant Bit (LSB) steganography technique is the most used technique to hide secret information in the least significant bit of the pixels in the stego-image. This paper proposed a technique by splitting the secret message into set of segments, that have same length (number of characters), and find the best LSBs of pixels in the stego-image that are matched to each segment. The main goal of this technique is to minimize the number of LSBs that are changed when substituting them with the bits of characters in the secret message. This will lead to decrease the distortion (noise) that is occurred in the pixels of the stego-image and as result increase the immunity of the stego-image against the visual attack. The experiment shows that the proposed technique gives good enhancement to the Classic Least Significant Bit (LSB) technique.

Paper 12: Simple and Efficient Contract Signing Protocol

Abstract: In this paper, a new contract signing protocol is proposed based on the RSA signature scheme. The protocol will allow two parties to sign the same contract and then exchange their digital signatures. The protocol ensures fairness in that it offers parties greater security: either both parties receive each other's signatures or neither does. The protocol is based on offline Trusted Third Party (TTP) that will be brought into play only if one party fails to sign the contract. Otherwise, the TTP remains inactive. The protocol consists of only three messages that are exchanged between the two parties.

Paper 14: A Digital Ecosystem-based Framework for Math Search Systems

Abstract: Text-based search engines fall short in retrieving structured information. When searching for x(y+z) using those search engines, for example Google, it retrieves documents that contain xyz, x+y=z, (x+y+z) =xyz or any other document that contain x, y, and/or z but not x(y+z) as a standalone math expression. The reason behind this shortage; is that the text-based search engines ignore the structure of the mathematical expressions. Several issues are associated with designing and implementing math-based search systems. Those systems must be able to differentiate between a user query that contains a mathematical expression, and any other query that contains only a text term. A reliable indexing approach, along with a flexible and efficient representation technique are highly required. Eventually, text-based search systems must be able to process mathematical expressions that are well-structured and have properties that make them different from other forms of text. Here, in this context we take advantage from the concept of digital ecosystems to refine the text search process so it becomes applicable in searching for a mathematical expression. In this research, a framework that contains the basic building blocks of a math-based search system is designed.

Paper 16: OCC: Ordered congestion control with cross layer support in Manet routing

Abstract: In the recent times many accessible congestion control procedures have no capability to differentiate involving two major problems like packet loss by link crash and packet loss by congestion. Consequently these resolutions effect in form of wastage of possessions because they target only on the packet drop by link crash that has a needless importance. Consumption of energy and possessions in order to make the basis node attentive regarding the congestion occurring in routing path is the supplementary drawback in most of the accessible procedures. This way of concentrating mainly on standardizing the outlet load at the basis node stage is the boundary to the present accessible procedures. It is already known that as a reason of link crash and congestion packet loss in the network routing largely occurs. In this article a new cross layer and path restoration procedure has been put forward. We also put forwarded two algorithms namely Path discovery Algorithm and congestion handling algorithm. In this approach of cross layer it comprises of 3 kinds of layers called network, MAC and transport layers. In this introduced approach the MAC and network layers have dynamic functionalities in identifying the congestion and standardization where the functionalities of network and transport layers are distinguished in bearing the congestion i.e. congestion endurance. The produced tentative results illustrate an enhanced management of congestion and its endurance by this approach.

Paper 19: RC4 stream cipher and possible attacks on WEP

Abstract: In this paper we analyze and present some weaknesses and possible attacks on the RC4 stream cipher which were published in many journals. We review some advantages and disadvantages which come from several authors, as well as similarities and differences which can be observed in the published results. Also, we analyze the Key Scheduling Algorithm (KSA) which derives the initial state from a variable size key, and strengths and weaknesses of the RCS stream cipher. Using examples from other papers, we show that RC4 is completely insecure in a common mode of operation which is used in the widely deployed Wired Equivalent Privacy protocol (WEP, which is part of the 802.11 standard).

Paper 20: Transforming Conceptual Model into Logical Model for Temporal Data Warehouse Security: A Case Study

Abstract: Extraction–transformation–loading (ETL) processes are responsible for the extraction of data from several sources, their cleansing, customization and insertion into a data warehouse. Data warehouse often store historical information which is extracted from multiple, heterogeneous, autonomous and distributed data sources, thereby, the survival of the organizations depends on the correct management, security and confidentiality of the information. In this paper, we are using the Model Driven Architecture (MDA) approach to represent logical model requirements for secure Temporal Data Warehouses (TDW). We use the Platform-Independent Model (PIM) which does not include information about specific platforms and technologies. Nowadays, the most crucial issue in MDA is the transformation between a PIM and Platform Specific Models PSM. Thus, OMG defines use the Query/View/Transformation (QVT) language, an approach for expressing these MDA transformations. This paper proposes a set of rules to transform PIM model for secure temporal data warehouse (TDW) to PSM model, we apply the QVT language to the development of a secure data warehouse by means of a case study.

Paper 21: Web Anomaly Misuse Intrusion Detection Framework for SQL Injection Detection

Abstract: Databases at the background of e-commerce applications are vulnerable to SQL injection attack which is considered as one of the most dangerous web attacks. In this paper we propose a framework based on misuse and anomaly detection techniques to detect SQL injection attack. The main idea of this framework is to create a profile for legitimate database behavior extracted from applying association rules on XML file containing queries submitted from application to the database. As a second step in the detection process, the structure of the query under observation will be compared against the legitimate queries stored in the XML file thus minimizing false positive alarms.

Paper 22: An Improved Grunwald-Letnikov Fractional Differential Mask for Image Texture Enhancement

Abstract: Texture plays an important role in identification of objects or regions of interest in an image. In order to enhance this textural information and overcome the limitations of the classical derivative operators a two-dimensional fractional differential operator is discussed, which is an improved version of the Grunwald-Letnikov (G-L) based fractional differential operator. A two dimensional-isotropic gradient operator mask based on G-L fractional differential is constructed. This nonlinear filter mask is implemented on various texture enriched digital images and enhancement of features of image is controlled by varying the intensity factor. In order to analyze the enhancement quantitatively, information entropy and average gradient are the parameters used. The results show that with improved version of Grunwald-Letnikov, fractional differential operator information entropy of image is improved by 0.5.

Paper 23: A Comparative Study on Temporal Mobile Access Pattern Mining Methods

Abstract: Mobile users behavior patterns is one of the most critical issues that need to be explored in mobile agent systems. Recently the algorithms of discovering frequent mobile user’s behavior patterns have been studied extensively. Existing mining methods have proposed frequent mobile user's behavior patterns statistically based on requested services and location information. Therefore, other studies considered that the mobile user's dynamic behavior patterns are usually associated with temporal access patterns. In this paper, temporal mobile access pattern methods are studied and compared in terms of complexity and accuracy. The advantages and disadvantages of these methods will be summarized as well.

Paper 24: A Schema for Generating Update Semantics

Abstract: In this paper, we present a general schema for de ning new update semantics. This schema takes as input any basic logic programming semantics, such as the stable semantics, the p-stable semantics or the MMr semantics, and gives as output a new update semantics. The schema proposed is based on a concept called minimal generalized S models, where S is any of the logic programming semantics. Each update semantics is associated to an update operator. We also present some properties of these update operators.
