This chapter examines practical applications of an educational program designed to teach Turkish gifted second, third, and fourth grade students programming using Scratch, an online programming website (https://scratch.mit.edu). This qualitative research study was conducted with gifted identified students in an elementary school in Ankara's Altındağ district. Qualitative data collection methods were used. The study found program strengths included practical orientation, student independence, student free expression, computer literacy, and interdisciplinary connections. Additionally, providing a variety of tools and equipment, using Scratch, having a course web site, and on-line resource sharing were also seen as strengths by the participants. Perceived weaknesses were technical difficulties, the limited number of course hours, some of Scratch's negative features, inadequate help at particular points, and negative situations caused by gender and grade level differences. Results indicate preliminary knowledge of participant computer literacy as important to programming success.

Waste load allocation for rivers has been a topic of growing interest. Dynamic programming based algorithms are particularly attractive in this context and are widely reported in the literature. Codes developed for dynamic programming are however complex, require substantial computer resources and importantly do not allow interactions of the user. Further, there is always resistance to utilizing mathematical programming based algorithms for practical applications. There has been therefore always a gap between theory and practice in systems analysis in water quality management. This paper presents various heuristic algorithms to bridge this gap with supporting comparisons with dynamic programming based algorithms. These heuristics make a good use of the insight gained in the system's behaviour through experience, a process akin to the one adopted by field personnel and therefore can readily be understood by a user familiar with the system. Also they allow user preferences in decision making via on-line interaction. Experience has shown that these heuristics are indeed well founded and compare very favourably with the sophisticated dynamic programming algorithms. Two examples have been included which demonstrate such a success of the heuristic algorithms.

Application Potential

The oil-line electrostatic sensor (OLES) is a new online monitoring technology for wear debris based on the principle of electrostatic induction that has achieved good measurement results under laboratory conditions. However, for practical applications, the utility of the sensor is still unclear. The aim of this work was to investigate in detail the application potential of the electrostatic sensor for wind turbine gearboxes. Firstly, a wear debris recognition method based on the electrostatic sensor with two-probes is proposed. Further, with the wind turbine gearbox bench test, the performance of the electrostatic sensor and the effectiveness of the debris recognition method are comprehensively evaluated. The test demonstrates that the electrostatic sensor is capable of monitoring the debris and indicating the abnormality of the gearbox effectively using the proposed method. Moreover, the test also reveals that the background signal of the electrostatic sensor is related to the oil temperature and oil flow rate, but has no relationship to the working conditions of the gearbox. This research brings the electrostatic sensor closer to practical applications.

This study aims to explore the Lebanese sociolinguistics as manifested in chatting, that is, to assess how a sample of Lebanese students use their languages skills while carrying an on-line conversation via chatting. The research will also investigate the variations governed by sociolinguistics branding the Lebanese chatting community. To carry out this study, a mix approach of quantitative and qualitative methodology is used. Indeed, the research will describe the participants’ computer literacy and how this is interrelated to the choice of chatting language. The researcher uses two methods, formal interviews with selected chatters and a survey questionnaire that reflects both linguistic issues and computer and chatting literacy. Data analysis uses SPSS version 25 software and performed descriptively. Findings show that although having a multilingual society is considered a positive and uplifting certitude, this fact should not be taken for granted and languages must be directed properly. Students cannot be left without guidance to the use of any language.

The present paper discusses the mathematical modeling of risers and riser-like structures applied in a positioning context for deep-water floating vessels. The main purpose of the paper is to show that an estimate for the optimal vessel position, sufficient for most practical applications, is obtained from measurements of the riser inclinations or related parameters at lower end, and optionally upper end, through a solution based on the variably tensioned beam differential equation. Due to the ease of implementation this solution is well suited for direct application in on-line riser monitoring systems. The method is an attractive alternative to on-line FE-analyses, application of pre-computed regression curves based on idealized loading or black-box neural networks, which has been proposed by others to be applied as basis for interpretation of the measured riser responses. The basic idea behind the method is based on the observation that the riser inclinations or stress-joint moments at upper and lower end have mainly two causes. Firstly an effect caused by the position of the riser top end relative to the wellhead due to permanent vessel offset and slow drift vessel motions, and secondly the effects of transverse current down the riser. The general theory behind the method will be outlined. It will then be shown how the method adapts to drilling-risers with flex-joints, risers with stress-joints and also to the special case of well intervention with coiled tubing in open sea without applying a work-over or marine riser. The performance of the method is illustrated using simulated vessel and riser dynamic response data. The simulations are performed for selected vessel types both for deep-water and shallower waters applying state-of-the-art software for simulation of the riser and vessel dynamic response in random sea states.

The Classroom Practices Survey was conducted by The National Research Center on the Gifted and Talented (NRC/GT) to determine the extent to which gifted and talented students receive differentiated education in regular classrooms. Six samples of third and fourth grade teachers in public schools, private schools and schools with high concentrations of four types of ethnic minorities were randomly selected to participate in this research. The major finding of this study is that third and fourth grade classroom teachers make only minor modifications in the regular curriculum to meet the needs of gifted students. This result holds for all types of schools sampled. It also holds for classrooms in different parts of the country and for different types of communities. Implications of these findings for researchers and gifted education specialists are discussed.

Basic Content

A major goal of the mathematics curriculum for third- and fourth-grade students is the development of numeration and computation skills. These skills are frequently maintained through routine drill. Most gifted students have a strong dislike for drill, preferring activities that require the use of higher cognitive processes. One way of providing for these students is to present them with problems related to the basic content that also enhance their problem-solving abilities.

Computational Visualization

The grid has the potential to transform collaborative scientific investigations through the use of closely coupled computational and visualization resources, which may be geographically distributed, in order to harness greater power than is available at a single site. Scientific applications to benefit from the grid include visualization, computational science, environmental modelling and medical imaging. Unfortunately, the diversity, scale and location of the required resources can present a dilemma for the scientific worker because of the complexity of the underlying technology. As the scale of the scientific problem under investigation increases so does the nature of the scientist's interaction with the supporting infrastructure. The increased distribution of people and resources within a grid-based environment can make resource sharing and collaborative interaction a critical factor to their success. Unless the technological barriers affecting user accessibility are reduced, there is a danger that the only scientists to benefit will be those with reasonably high levels of computer literacy. This paper examines a number of important human factors of user interaction with the grid and expresses this in the context of the science undertaken by RealityGrid, a project funded by the UK e-Science programme. Critical user interaction issues will also be highlighted by comparing grid computational steering with supervisory control systems for local and remote access to the scientific environment. Finally, implications for future grid developers will be discussed with a particular emphasis on how to improve the scientists' access to what will be an increasingly important resource.

Set Up

A persistent practical problem in high resolution electron microscopy has been the diffulty to obtain careful, statistical comparisons between experimental and theoretical images. As a rule, practical applications of image simulation have involved either a direct comparison of calculated and experimental images, or a comparison of digitized images from a microdensitometer. Both of these pose substantial impediments to the final goal of HREM, namely R-factor measurements of the agreement between experimental and theoretical images.As a step beyond these approaches, we have recently finished bus-interfacing a framestore device to an Apollo 3000 workstation. The full set-up is shown in Figure 1. The framestore device, an IMAGING 151 set of boards, can perform all the standard video rate processes such as recursive filtering, as well as accumulating a 16 bit image. This device is fully integrated into the Apollo mini-computer, and is set up so that images can be directly transferred to disk within the SEMPER software system.
