Mel Frequency Cepstral Coefficients (MFCCs) are the most popularly used speech features in many speech and speaker recognition applications. In this paper, we study the effect of the second-order derivatives of MFCC on the recognition of the Spoken Arabic digits. The system was developed using the Hidden Markov Models (HMMs) and Tree distribution approximation model. Experimentally it has been shown...
Although the Web, cell phone ‘apps’ and cloud computing put a world of information at our fingertips, that information is under constant threat from cyber vandals and hackers. While awareness of information threats is growing in the Western world, in places like Saudi Arabia, information security is very poor. Unlike Western pluralistic democracies, Saudi Arabia is a highly-censored country, with...
Social networks usually involve rich collections of objects, which are jointly linked into complex relational networks. Analyzing these networks for information has gained significant attention in recent years, largely due to the success of online social networking and media-sharing sites like FaceBook, and the consequent availability of a wealth of social network data. Recent past has seen an enormous...
Baseline prediction is an important to devise marketing strategy for a consumer goods product. Simulation techniques, time series algorithms are often used to generate baseline for the future. However the algorithm that fits a particular point of sales (POS) data varies according to the datasets. Sample set of point of sales data were simulated under different conditions and constraints incorporating...
FlexRay is a vehicular communication protocol designed by the FlexRay Consortium since 2000 to meet growing requirements in hard real time automotive systems and to support Time Triggered as well as Event Triggered paradigms. FlexRay is designed to be faster and more reliable than the Controller Area Network (CAN) and The Time Triggered Protocol (TTP) in order to provide communication infrastructure...
Most of data on the Web are still stored in relational databases. Therefore, it is more important to make the correspondence between relational databases (RDB) and ontologies for storing the Web data. In this paper, we present an new approach to map the data stored in relational databases into the Semantic Web, we exploit simple mappings based on some specifications of the database schema, and we...
Avoiding the “curse of dimensionality” in contentbased image retrieval becomes one of the most essential tasks to achieve because of the high number of stocked images as well as the high dimensionality of the descriptive vectors' space. In this context, our work consists on minimizing low-level features describing an image by using a reduced descriptor that combines color and texture information which...
Modeling and managing Supply chain management systems that span multiple organizations involves new challenges, mainly regarding the ability to cope with change on the wide variety of languages and technologies which are heterogeneous in permanent evolution. The goal of our work is to contribute to the field of modeling and designing Supply chain management systems. Let's put forward a methodological...
In this paper the authors investigate the task of authorship attribution on very old Arabic texts that were written by ten ancient Arabic travelers. Several features such as characters n-grams and word n-grams are used as input of a SMO-SVM (i.e. Sequential Minimal Optimization based Support Vector Machine). Experiments of authorship attribution, on this text database, show interesting results with...
Arabic has special features that cannot be found in other languages. Almost all software programs that support Arabic do not handle features like semantic and grammar. For this reason we have developed an intelligent morphological Arabic Analyzer that can predict the correct semantic of Arabic sentences and then deliver the correct grammatical form of the sentence with text and voice. Our proposed...
In this paper, a component splitting and local model selection method is proposed to address the mission of learning and selecting generalized Dirichlet (GD) mixture model with feature selection in an incremental variational way. Under the proposed principled variational framework, we simultaneously estimate, in a closed-form, all the involved parameters and determine the complexity (i.e. both model...
Mobile technology and mobile applications evolution have increased possibilities for mobile learning (ML). However, the lack of perceived learning value and institutional infrastructure are hindering the possibilities for ML attempts. The purpose of our study is the understanding opportunities and obstacles of mobile technologies as perceived by teachers in higher education. A questionnaire was developed...
The present paper introduces a new category of games which could be ranked among the collaborative games. This “collaboration-oriented game” has the distinction of being based on the solidarity and collaboration rather than individualism and competition. It puts forward team spirit over the individual one and serves to enhance the collaboration skills for players. The collaboration-oriented game aims...
Equipped with powerful processors, cameras for capturing still images and video, and a range of sensors capable of tracking location, orientation and motion of the user, modern smartphones offer a sophisticated platform for implementing handheld augmented reality (AR) applications. Despite the advances in research and development, implementing AR applications for the smartphone platform remains a...
A recent trend in the study of UML formal semantics is to integrate semantics of various UML diagrams into a single framework. The aim is to get a unified basis for main research topics like validation, verification and syntax checking. In this paper, we propose an approach based on the Situation Calculus (SC) which is a sophisticated action theory and is capable of modeling general systems. UML models...
SOA enables integration of applications and resources flexibly, representing every application or resource as a service. It still suffer from no clear specifications to define this concept as the architectural style, and in particular, it has performance problem related to the creation of services that affect the total processing time of the system. We have defined more clearly SOA by providing a...
Several companies report success stories after migration from relational database management systems to NoSQL systems (Not only SQL). The latter seem to take over in most data storage fields. These technologies must be used properly, and businesses must be aware of the limitations of NoSQL, for providing real benefits. Pig Latin is a high-level language for expressing data analysis programs, and implementing...
