Abstract: Mathematical content has many ambiguities (the same symbol used for different purposes

etc) which are not understood by the current search systems. The current search systems have their

focus placed on the search by keywords of the mathematical terms, symbols and formulas. This paper

introduces a Mathematical Dictionary System (MDS) which contains three dictionaries: The first is a

mathematical terms dictionary from/to Malay to English. Secondly, a mathematical symbols dictionary

that contains three classes of symbols; Greek symbols, operation symbols and notation symbols.

Thirdly, there is the mathematical formulas dictionary that contains six classes of formulas; number

system, polynomials, sequences, functions, differentiation and integration. MDS has two categories of

users, namely students and lecturers. The MDS has two processes; inserting data, and updating data.

Data can come in the forms of new symbols, new formula, and new terms (English-Malay terms or

English-Arabic terms). Lecturers can even add new data. There is also a keyboard for mathematical

symbols which is displayed on the screen. MDS provides multiple ways of searching. Searching can be

narrowed to finding a symbol, a formula, a part of word, and a keyword. Users can listen to the

pronunciation of words after they search; and it is considered as another added value for the MDS

besides searching. The results of the usability test show that the system is easy to learn, and it is

relatively efficient to use.

ABSTRACT:Web-based forum is an application through the internet to facilitate the process of discussions and exchange of ideas. It is also referred to as online forums, message boards, discussion groups, and discussion forums. Youth can play a role in shaping their societies of immense diversity through the means of communication and participation, and sharing ideas. Therefore, this study leads to develop a web-based forum application to help young people express themselves and their needs, and desires. The requirements of the webbased application were identified from the students in UUM who are in the similar age group, design the application, and a prototype to implement the design. ---------------------------------------------------------------------

Information Communication Technologies (ICTs) provide an opportunity to meet the growing needs of rural areas. Many of the key features of ICT can be used to provide information and the requirements of people in rural areas. The digital divide considered is an important problem that countries face and it is much more complex than simply building out telecommunication networks and infrastructure. The divide is the result of a wide range of social factors, including but not limited to economy factors, education, literacy. Telecommunication infrastructure alone will not guarantee that users will be able to access and take advantage of services on the network. The paper begins with an introduction to the digital divide, and thus to highlight several successful initiatives provided by educational institutions and governmental organizations in Libya in the adoption of ICT. Finally, the paper provides some of the solutions proposed to reduce this divide.

The use of computers for handling image data in the healthcare is growing The amount of data produced by modem image generating techniques, such as Computed Tomography (CT) and Magnetic Resonance (MR), is vast. The amount of data might be a problem from a storage point of view or when the data is sent over a network. To overcome these problems data compression techniques adapted to these applications are needed Many classes of images contain some spatial regions which are more important than other regions. Compression methods which are capable of achieving higher reconstruction quality of important parts of the image have been implemented For medical images, only a small portion of the image might be diagnostically useful but the cost of wrong interpretation is high. Algorithms which deliver lossless compression within the regions of interest (ROJ), and lossy compression elsewhere in the image, might be the key to providing efficient and accurate image coding to the medical community. In this thesis both of compression techniques (lossy and lossless) of medical images using the JPEG algorithm (DCT), will be discussed.
