Nowadays, touch screen technology makes drawing a sketch easier. It also makes searching and surfing easier for disabled children. Retrieving images with a sketch is a highly desired feature for disabled children with autism. The image retrieval system was defined as a computer system for searching, browsing and accessing the image. It is not easy for autistic children to recognize suitable keyword because of their lack of processing ability and memorizing the information in their mind; otherwise they are good in drawing sketch. In this paper, attention is placed on developing an image retrieval search engine based on sketch to aid children with Autism Spectrum Disorders in retrieving relevant images without needing to insert text based input.

RFID tags are increasingly used for identifying and tracking purposes. In many applications, such as shop gateways, it is possible that more than one tag come within the range of the reader, which may interfere with the detection of tags or the data exchange. This paper presents a method based on the combination of CSMA and query tree to manage multiple accesses and avoid collision. This method is implemented in two stages. First, the tags with the unique short addresses are detected, and then remaining tags are identified in the next stage. The simulation results of the proposed method in MATLAB Software show improved common access parameters and reduced latency compared to the similar methods, which is due to the processing of the shortened address rather than the whole address.

This paper focusses on the concept of random variables and probability in making a cricket management game through C++ programming. For a finite number of outcomes which occur on each ball that is bowled, a discrete random variable is generated and the outcome probabilities are estimated from the data being used in the game. The probability in the game has an effect on the batsman, number of wickets lost and number of balls remaining. The game behaves like a simulator which is used to predict the outcome in the matches being played by the user. The game is designed in such a way that the sample space changes, and the probability of the random variable generated changes as well according to the in-game options and decisions made by the user. The concept of random variables and probability is applied to make the foundation logic for this game. The skills help in understanding what strategy can be implemented to be on the winning side. The study is developed with an attempt to realistically model a T20 cricket match, and to help in reflecting major tendencies.

Quasi static finite element analysis (FEA) was conducted on precast light weight foamed concrete sandwich panel (PLFP) using ABAQUS/Explicit module to study its structural behavior. The PLFP subjected to axial load was simulated under perfect and imperfect conditions. Results from the FEA were validated with experimental data accurately. The analysis produced ultimate load carrying capacity, damage criteria and vertical and horizontal displacement. It was found that the proposed finite element model for PLFP with perfect and imperfection conditions can predict the structural behavior of PLFP accurately. Therefore, a computational study by using FEA can be used as an economical alternative tool to replace the experimental study of structural behavior of PLFP.
