Instructional contents are used to demonstrate a technical process to teach and walkthrough certain procedures to carry out a task. This type of informational content is widely used for teaching and lectures in form of tutorial videos and training videos. Since there are questions and uncertainties for what could be the killer application for the novel wearables, we propose a self-instruction training application on a smart glass to utilize already-available instruction videos as well as public open data in creative ways. We design and implement a prototype application to help users train by wearing smart glasses specifically designed for two concrete and hand-constrained use cases where the user's hands need to be free to operate. To increase the efficiency and feasibility of the self-instruction training, we contribute to the development of a wearable killer application by integrating a voice-based user interface using speech recognizer, public open data APIs, and timestamp-based procedural content navigation structure into our proof-of-concept application.

UML cannot meet all the requirements offered in different software system for diverse application domain. GNSS (Global Navigation Satellite System) application domain is an especial environment that requires precise measurement and precision calculation of real-world geographical entities with the help of GPS (Global Position System) in both temporal and spatial factor. Therefore in the paper new extended iconic stereotypes for better modeling GNSS application in the UML Diagram are proposed, and the implementation of a program called StereotypeCreator, which is able to create iconic stereotypes used in one of the most popular visual modeling tools for software development, Rational Rose, will be also proposed.

This work investigates the accuracy and performance of a $FE^2$ multi-scale implementation used to predict the behavior of composite materials. The equations are formulated assuming the small deformations solid mechanics approach in non-linear material models with hardening plasticity. The uniform strain boundary conditions are applied for the macro-to-micro transitions. A parallel algorithm was implemented in order to solve large engineering problems. The scheme proposed takes advantage of the domain decomposition method at the macro-scale and the coupling between each subdomain with a micro-scale model. The precision of the method is validated with a composite material problem and scalability tests are performed for showing the efficiency.

With the rapid increase of user generated data on digital platforms, the task of categorizing and classifying theses huge data has become difficult. Topic modeling is an unsupervised machine learning technique that can be used to get a summary from a large collection of documents. Topic modeling has been widely used in English content, yet the application of topic modeling in Arabic language is limited. Therefore, the aim of this paper is to provide a systematic review of the application of topic modeling algorithms in Arabic content. Using a well-known and trusted databases including ScienceDirect, IEEE Xplore, Springer Link, and Google Scholar. Considering the publication date from 2012 to 2022, we got 60 papers. After refining the papers based on predefined criteria, we resulted in 32 papers. Our result show that unfortunately the application of topic modeling techniques in Arabic content is limited.

The current Sudanese preschool system depends on limited methods of education, children's education needs to be equipped to keep pace with technological development, also, the large gap that exists between the families and the Kindergartens, where many parents have no idea on how their child progresses in the KG context. The aim of this research is to integrate ICT in the preschool education to enhance and improve the preschool education, by building an Integrated Educational Application (Computerized Application for Preschool Education CAPE) which will help to improve the learning outcomes. The researchers used the Experimental Research Methodology, the characteristic of CAPE application is; suitable for children's age, the application style is more attractive to the children and contains a different way to help children get learning. Alawaeel and the Smart Child Kindergartens in Republic of Sudan were selected as a sample of the study, with sample size specifically, 50 children's. Also, the Central Bank of Sudan Kindergarten was selected as one of the institutional Kindergartens for easy communication with parents of children with a sample size 21 children. The study found that; using CAPE application in KG enables children to increase general learning effects and developing child's cognitive skills. Also, the children who were allowed to use CAPE by their parents are performed better in the overall evaluation of KG lessons. Also, using the CAPE in the Pre-School education helps the parents following their children's progress better and more reliable. The researcher recommends that to apply the computerized application and includes the second level. Also, converting the computerized program into an application to be used by children by their self, without the intervention of parents.

The great development of the modern science enables the information technology including computer to be promoted, which has the great effects on the whole design field. Most of all, the computer has the feature to express the mathmatical formular through the logic and system, which is being used very efficiently in the design work. CG application to the two-dimensional design may be limited in promoting the basic ability synthetically through the direct and molding experience for its attribute, however, it is possible to create the effects on the different level in addition to those from the traditional skill. In particular, we should keep the fact in mind that the CG application in the design field will be able to accomplish the object only under understanding the attributes and functions for it to have. We should carry out the task to agree with. First, it is necessary to develop the various study on the educational environment to make the process to solve the problems and to promote the effects of the educational media in teaching design with the CG application. This study would make plans to approach that the computer can be utilized for the main method to create design despite of being limited in some point. Moreover, it suggests the possibility for the CG application in the course of building up and motiving the models by applied the basic system, which enables the computer to be applied centering around the composition of geometry pattern of the basic course of the two-dimensional design.

본 논문은 무선 센서 네트워크를 이용하여 동적 애플리케이션 프레임워크 기반의 데이터 수집 및 모니터링 기법을 제안한다. 무선 측정 노드의 펨웨어 프로그램을 위한 애플리케이션 개발의 최적화를 통해서 다양한 센서들과의 통합 및 제어를 수행한다. 사용자 애플리케이션의 수집 데이터는 노드의 온보드 프로세서에서 무선으로 다운로드되고, 노드의 온도 초기값 설정을 사용자 애플리케이션으로부터 변경을 지시할 수 있으므로 측정 노드의 동적 샘플링이 가능하다. 따라서 노드의 동적 샘플링 제어를 통해서 기존의 유선 기반의 데이터 모니터링에 비해 센서의 소비전력을 감소시킬 수 있다.
