Abstract: The virtual lab is one of the new fields developed to enhance the remote learning programs which have proved useful in terms of time and place bounds that come with the traditional learning systems. It provides students with access to execute experiments on remote laboratories via internet or network connections. A Virtual Lab system consists of three major parts: The server PC, the client PC and the lab devices. The server is connected to the client via Internet/network connection, and it’s also connected to the lab devices via a hardware port (such as the Parallel Port).

Abstract: Indoor wheelchairs can be used for limited needs users, especially people with lower limb paralysis or spinal cord injuries which require limited speed motion. The aim of this study is to modify the actual design of the manual driven wheelchair to an electrically powered wheelchair. Controlling method for speed and motion was used and constructed using MULTISIM program Version (9). Feedback controlling system using Tachometer feedback voltage signal is used which make the system more stable. This method was chosen from many ways to control the DC motor.

Abstract: Segmentation of MR images was formulated in this thesis as the problem of partitioning a set of feature vectors obtained from an MR image into a relatively small number of clusters. Segmentation of MR images is formulated as an unsupervised vector quantization process, where the local values of different relaxation parameters form the feature vectors which are represented by a relatively small set of prototypes.
