In this paper, both content analysis and Romey analysis were employed to analyze three 'General Computer' textbooks used in commerce and information high schools. The content analysis was employed to study the organization and contents of the textbooks, whereas the Romey analysis to determine the inquisitive tendency of four sections - Text, Data, Activity and Evaluation. The results from the content analysis showed that textbooks differed in the number of subsections, the number of pages in each section, and the number of concepts introduced in each section. Also, results from the Romey analysis demonstrated that the section Text in all the textbooks was written with a low level of inquisitive tendency, but also that they differed in that two other sections Data and Activity in one textbook exhibited a high level of inquisitive tendency while the other section Evaluation in two textbooks did. Using the aforementioned results, we proposed ways to improve the readability of 'General Computer' textbooks.

Based on the multiple-time-scale (MTS) method, a general formula has been presented for solving an n-th, n = 2, 3, ${\ldots}$, order ordinary differential equation with strong linear damping forces. Like the solution of the unified Krylov-Bogoliubov-Mitropolskii (KBM) method or the general Struble's method, the new solution covers the un-damped, under-damped and over-damped cases. The solutions are identical to those obtained by the unified KBM method and the general Struble's method. The technique is a new form of the classical MTS method. The formulation as well as the determination of the solution from the derived formula is very simple. The method is illustrated by several examples. The general MTS solution reduces to its classical form when the real parts of eigen-values of the unperturbed equation vanish.

This research explored the impact the thoughts and opinions of lecturers teaching university general English courses have on their virtual classes and discussed the differences and similarities in their perspectives. As a research methodology, the Q-method was used, which usually consists of five steps: Q-population, Q-statements, Q-participants, Q-sorting, and factor analysis using PQMethod, a computer software program. A total of 30 statements were finally selected and 26 people directly involved in teaching online university general English courses were selected as participants in this study. Based on the results of the factor analysis, this research discovered three different factors, which were interaction & content-oriented, online teaching favored, and content-oriented. The results of this study can contribute to developing the future directions of virtual university general English classes to help learners improve their English skills and prepare lecturers for the future.

This study is to construct a general purpose library for a computer vision system development. The library includes many core algorithms required for computer vision systems such as image Processing algorithms, feature extracting methods, neural networks and etc. We have experimented the efficiency of the library by building a vehicle plate recognition system and the overall time and effort in development could be reduced to a certain extent.

Plane sweep is a general method in computational geometry. There are many efficient theoretical algorithms designed using plane sweep technique. However, their practical implementations are still suffering from the topological inconsistencies resulting from the numerical errors in geometric computations with finite-precision arithmetic. In this paper, we suggest new implementation techniques for the plane sweep algorithms to resolve the topological inconsistencies and construct the planar object boundaries from given input curve segments.

We consider a more general linear regression super-population model than the one of Chaudhuri and Stronger(1992) . We can find the same type of the best linear unbiased(BLU) predictor as that of Chaudhuri and Stenger and see that the optimal design is again a purposive one which prescribes choosing one of the samples of size n which has $\chi$ closest to $\bar{X}$.

There is no assurance that malware could only cause virtual damage to computer programs and data as its potential is endless. However, legal provisions were earlier developed to cater to either a physical damage caused by a physical action or a virtual damage caused by a virtual action. When crossovers occur, it becomes quite uncertain as to how viable the current laws are in handling this matter. The author seeks to address the issue from the perspective of the laws of Malaysia.

The purpose of the paper was to investigate students' perceptions of tablet computer-based mobile learning in a middle school. We examined the perceptions in terms of: 1) learning effectiveness, which refers to the effects of tablet computer on learning outcomes such as the grade; 2) attitude change, which is the change of students' attitudes and study habit; 3) learning activities, which refers to the kinds of learning activities using tablet computer; and 4) computer utilization, which is the ways of computer use in the study. The result showed that, in general, tablet computer affected all four types of perceptions positively.
