Capacitance testing is the most important for the service bushing condition assessment. However, for the new Resin Impregnated Paper (RIP) bushing used in EGAT, the repeatable test result quite deviates. The aim of this paper is to investigate the root cause of the unrepeated testing values of the test tap capacitance for the installed new RIP bushings compared with factory values. The measurement results of test tap capacitance were collected from ten installed 123 kV bushings. Those results deviated from the factory values of approximately 33%. A new RIP bushing was used to set up the laboratory test experiment. The laboratory test used a portable insulation power test set to measure the test tap capacitance. The aluminum foil and the sheet metal were used to wrap around the bottom part of the bushing for simulation of the ground electrode and leakage current guarding. Onsite measurement was performed with an installed bushing with BCT (bushing current transformer) by grounding BCT and guarding of the leakage current of BCT. It was found that the test tap capacitance was decreased with increasing the diameter of the simulated ground electrode and decreased with the application of the leakage current guarding. The test results showed that the bottom part of the RIP bushings without the ground sleeve and conditions of BTC such as the diameter of bushing pocket, installation with or without BCT mainly impacted the unrepeated test tap capacitance.

Web pages and their embedded documents are a good source of information. However, issuing complex queries directly on web pages using direct pattern-matching techniques are challenging tasks that require lengthy procedural programming. Also, programmers working directly on web pages are in charge of the search path and routing, which depend on individual document structures and affect the correctness, completeness, and performance of the results. In contrast, relational databases are well-structured and backed by mathematical principles. Well-designed relational database structures are known to be anomalies-free. The standard relational database language, SQL, is a non-procedural language that defines the required results precisely. Query results are both correct and complete. Performance issues are handled by intelligent query optimizers employed by modernday Database Management System (DBMS). This paper suggests an approach that transforms documents embedded on web pages in HTML format to corresponding relational database structures and populations. Functional dependencies (FDs) and multi-valued dependencies (MVDs) obtained from documents on the webpages are used to construct conceptual schema diagrams, which are further transformed into the Optimal Normal Form (ONF) relational database structures. In this research project, the Object Role Model (ORM) conceptual schema model is employed. The paper discusses the ORM and the rationales behind its usage. The detection of FDs and MVDs from webpage documents and the technical properties of the ONF relational database structures. Illustrated examples are also provided.

Human Resource (HR) Analytics has been increasingly attracted attention for a past decade. This is because the study field is adopted data-driven approaches to be processed and interpreted for meaningful insights in human resources. The field is involved in HR decision making helping to understand why people, organization, or other business performance behaved the way they do. Embracing the available tools for decision making and learning in the field of computational intelligence (CI) and Artificial Intelligence (AI) to the field of HR, this creates tremendous opportunities for HR Analytics in practical aspects. However, there are still inadequate applications in this area. This paper serves as a survey of using the tools and their applications in HR involving recruitment, retention, reward and retirement. An example of using CI and AI for career development and training in the era of disruption is conceptually proposed.

As of 2020, more than 1,250 MW of renewable energy has already been integrated into the Integrated Nepal Power System (INPS). With another 3,150 MW of hydropower projects under construction, the domestic electricity demand is forecasted to be much lower than its production within a few years. As this added capacity is on the horizon, the Nepalese government needs to prioritize domestic utilization of generated power over exporting the excess generation to the international market. One of the means for this is introducing hydrogen technology in the Nepalese market. This paper discusses suitable hydrogen production methodology, particularly green hydrogen via electrolysis and further encompasses the areas of hydrogen where it could play a pivotal role in case of Nepal. Cost analysis of hydrogen production is also conducted for 50kW to 500kW system. However, as hydrogen technology is still in its infancy, a well-informed selection of technology should be emphasized for the production of hydrogen in the context of Nepal. Attributes such as high energy density and transportability make hydrogen a suitable energy carrier. Further, better energy management can be achieved with the use of fuel cells.

This paper presents a new circuit configuration of a transimpedance mode dc bridge based on an operational trans-resistance amplifier (OTRA) as an analog building block. The proposed circuit suits for small changing resistance detector. By taking the benefit of grounding property at the internal input port of the OTRA, a simple and compact dc bridge is obtained. The proposed circuit is composed of two sensing components together with a feedback resistor and only one operational trans-resistance amplifier. The circuit performances are verified by the PSPICE simulation using 0.35 $mu$m CMOS technology model parameters. The simulation results from circuit level agree well with the theoretical values.

Recently temporal supports have been included in the SQL standards, leading to a great bridge between research works and real-world applications. However, showing this bridge in practice needs to be considered more. Such a shortage needs to be resolved due to the fact that time is ubiquitous in every application domain. In this paper, we propose a novel design method to design a bitemporal SQL database from an enhanced-entity-relationship schema. From this conceptual schema, a bitemporal SQL database schema is defined automatically. As a theoretical evaluation, our proposed method is novel in the following points. Firstly, although the method is dedicated to bitemporal databases, its starting point is with the enhanced entity-relationship model which is so popular that practicing database designers can work with it well. Secondly, its temporal supports are explicitly extracted and included in the data model mapping in an automatic manner. The automatic mapping process is based on topological sorting and thus performed in a certain sequence to derive a bitemporal SQL database schema with the SQL temporal support. Above all, our method helps easily deploy bitemporal databases in real-world applications. Indeed, its illustration has been shown comprehensively for VNUMED, an intermediate research medical database.

This paper presents the automatic transfer function improvement based on the genetic algorithm for searching the optimal transfer function. A traditional genetic algorithm is modified to perform the searching process. The proposed chromosome design is presented in the form of 15-bit supported the resistance and inductance. Transfer function is used to design and control the systems. The optimal fitness function is used for the objective function of system to optimize the transfer function. Experiment results show that the second order of automatic transfer function performed by the genetic algorithm can achieve more accuracy than the traditional first order transfer function process. By the process improvement using the genetic algorithm, the time is used for searching transfer function with the chromosome design under the optimal fitness function by the genetic algorithm is approximately 13.35 seconds.

Due to the efficiency of the transportation system is very important for a developing country’s economy. Good management transportation services will help agencies provide sustainability services and for users satisfied. This research has two purposes: (1) to study the usage of large data to design hispeed train service and (2) to create a prototype model for hispeed train service from the master country to get the most benefit from applying for service in Thailand. The Country that has been brought to study for modeling is Japan. The data used in this research will consist of all hi-speed rail service information that is currently available and demographic. These data process by using big data technology and machine learning to help study. After studying we selected 2 suitable models to be used for creating prototype models: multiple linear regression and regression tree. The model predictive performance shows that the multiple linear regression model, which uses the mean square error to test the comparison between the baseline. This model presented in this research is significantly more accurate than baseline with confidence at 95% and from cross-validation in the training dataset. The best predictions have found that the data group consists of demographic data and service information. This model can accurately predict the amount of transportation per day. The findings from this study may directly benefit Thailand’s hi-speed train planners in their effort to develop an optimal train schedule and reduce the future train fare in Thailand.
