TL;DR: Some of the clustering techniques are described and some of the recent works by researchers on these techniques are discussed, which make it easier for further analysis of image processing.
Abstract: Image segmentation has been considered as the first step in the image processing. An efficient segmentation result would make it easier for further analysis of image processing. However, there exits many algorithms and approaches for image segmentation. Clustering is one of the commonly used image segmentation techniques. In this paper, we have briefly describe some of the clustering techniques and discuss some of the recent works by researchers on these techniques.

TL;DR: In this paper, three hands-on activities are described concerning the electromagnetic radiation and the main goal is to confirm the inverse square law, and they used three activities entitled as: "Inverse square law-Light", "Photometer construction", and "Radioactive source".
Abstract: Many concepts in the physics curricula can be explained by the inverse square law. Point-like sources of gravitational forces, electric fields, light, sound and radiation obey the inverse square law. This geometrical law gives the ability of unifying educational approach of various cognitive subjects in all the educational levels. During the last years we have been using engaging hands-on activities to help our students in order to understand the cohesion in Nature and to export conclusions from experimental data. The development of critical thinking is also stimulated by student‘s experimental activities. Teaching students to think critically is perhaps the most important and difficult thing we do as science teachers. In this paper three activities are described, which were executed by students. These activities are concerning the electromagnetic radiation and the main goal is to confirm the inverse square law. We used three activities entitled as: “Inverse square law-Light”, “Photometer construction” and “Radioactive source”. The significant motive for this work constituted the following question: “Is it possible to find lab activities which bring out unification and a non-piecemeal description of physical phenomena, helping students to think critically?”.

TL;DR: In this paper, the replacement of a third coarse aggregate was established as being the most suitable for retaining the properties of the concrete mix design, while the incorporation of glass sand regardless of the ratios of replacement showed no significant influence on fresh or mechanical properties of concrete except for the case of transparent bottles.
Abstract: Conventional concrete aggregate consists of sand (fine aggregate) and various sizes and shapes of gravel or stones (coarse aggregate). However, there is a growing interest in substituting alternative aggregate materials, largely as a potential use for recycled materials. While there is significant research on many different materials for aggregate substitutes such as granulated coal ash, blast furnace slag or various solid wastes including fiberglass waste materials, granulated plastics, paper and wood products or wastes, sintered sludge pellets and others. Recycled waste glasses were used as coarse and fine aggregates replacement in concrete. Coarse aggregates were replaced with Green Bottles coarse aggregates at third, half, two thirds, and 100% replacement ratios. The replacement of a third coarse aggregate was established as being the most suitable for retaining the properties of the concrete mix design. As for fine aggregates, in order to account for the numbers of variables and clearly establish a bench mark, the sand grading, color of glass, source of waste glass (bottles and non-bottles), and design mix strength were used as parameters. Fine aggregates from green, brown, and transparent bottles in addition to clear window waste glass were used. Concrete properties were tested in fresh and hardened states. The incorporation of glass sand regardless of the ratios of replacement showed no significant influence on fresh or mechanical properties of concrete except for the case of transparent bottles. Transparent bottles due to the wide source of obtainability have introduced a non-uniform factor that caused discrepancy compared to the rest of the group.

TL;DR: The present study aims to provide an expert system using the VP-Expert shell for diagnosing liver disease and block and Mockler charts have been used to provide the necessary knowledge in the expert system.
Abstract: The liver plays an important role in regulating the body's internal interactions as the largest and the most complex organs in the body. Such interactions are essential in preserving life and proper body function. The eaten foods are not consumed in the same way in the body. In fact, it should pass through the liver and after absorption and entering the blood, and the liver plays an important role in the storage of eaten substances. Accordingly, the speed of diagnosing and treating liver diseases are highly effective in improving patients' health; however, there is always a lack of immediate access to specialized physicians. The present study aims to provide an expert system using the VP-Expert shell for diagnosing liver disease. Also, block and Mockler charts have been used to provide the necessary knowledge in the expert system. In this regard, the factors affecting the diagnosis of the disease were firstly categorized into three groups of blood tests, clinical symptoms of illness and disease time on the block diagram for disease diagnose, and in the next step, the Mockler chart was designed according to the three groups of factors on the block chart. The three categories of disease diagnostic factors, questions corresponding sub-sections, and the response range are determined on Mockler chart, and finally, the tables are designed to express the system inference according to the user's answers to the questions.

TL;DR: Superconducting Fault Current Limiter (SFCL) is a flexible alternative to the use of conventional protective devices, due to its effective ways of reducing fault current within the first cycle of fault current, reduced weight and zero impedance during normal operation.
Abstract: The fault current levels of an interconnected power network have witnessed a general rise due to increase in power demand. This rise in fault current if not properly mitigated may exceed the maximum ratings of the switchgear. Many conventional protective devices such as series reactors, fuses, high impedance transformers, etc. have high cost, increased power loss and loss of power system stability, which may ultimately cause lower reliability and reduced operational flexibility. Superconducting Fault Current Limiter (SFCL) is a flexible alternative to the use of conventional protective devices, due to its effective ways of reducing fault current within the first cycle of fault current, reduced weight and zero impedance during normal operation. This paper reviews various concepts of SFCLs and its applications in power systems.
