The most commonly used method to describe the relationship between response and independent variables is a linear model with Gaussian distributed errors. In practical components, the variables under examine might not be mesokurtic and the populace values probably finitely limited. In this paper, we introduce a multiple linear regression models with two-parameter doubly truncated new symmetric distributed (DTNSD) errors for the first time. To estimate the model parameters we used the method of maximum likelihood (ML) and ordinary least squares (OLS). The model desires criteria such as Akaike information criteria (AIC) and Bayesian information criteria (BIC) for the models are used............

The last decades, electric power industry is undergoing multiple changes due to the process of deregulation, providing efficient power generation, technological innovations, and eventually lower retail prices. In this environment, dynamic phenomena in power systems have made ever more urgent the development of reliable tools for their monitoring and control. An effective tool for the close monitoring of their operation conditions is the state estimator. The traditional estimators are based on real time measurements obtained through SCADA (Supervisory Control and Data Acquisition) system. These measurements are commonly provided by the remote terminal units (RTUs) installed at the high voltage substations........

In high schools of Viet Nam, teaching calculus includes the knowledge of the real function with a real variable. A mathematics educator in France, Artigue (1996) has shown that the methods and approximate techniques are the centers of the major problems (including number approximation and function approximation...) in calculus. However, in teaching mathematics in Vietnam, the problems of approximation almost do not appear. With the task of training mathematics teachers in high schools under the new orientations, we present a part of our research with the goal of improving the contents and methods of teacher training.

Mobile application processors are soon to replace desktop processors as the focus of innovation in microprocessor technology. Already, these processors have largely caught up to their more power hungry cousins, supporting out-of order execution and multicore processing. In the near future, the exponentially worsening problem of dark silicon is going to be the primary force that dictates the evolution of these designs. We have argued that the natural evolution of mobile application processors is to use this dark silicon to create hundreds of automatically generated energy-saving cores are called conservation cores, which can reduce energy consumption by an order of magnitude.......

In Vietnamese mathematics curricula, primary school students explicitly learn the concept of quadrilaterals such as parallelogram, rhombus, rectangle, square and trapezoid in the Grades 3, 4 and 5. They are presented individually, and there is no comparison between their characteristics. Therefore, the students will be difficult to recognize the relationships among kinds of quadrilaterals. The results of an investigation of 186 primary school students revealed that most of them found it easy to identify squares and rectangles but many of them asserted that "a square is not a rectangle".

This paper proposes a low complexity shift register based on decoder enabled pulsed latches. Power consumption and Area reduction plays a major role in sequential circuit design. To reduce the area traditional flip-flops are replaced by pulsed latches. The timing problem of latches are solved by use of various non overlap delayed pulsed clock signals. Traditional shift register uses single pulsed clock signal for data transition, which consumes additional power. Here the single clock is divided into small number of pulsed clock and the shift register are combined by several sub shift registers..........

Ocean Thermal Energy Conversion (OTEC) is a technology by which thermal energy from the ocean is harnessed and converted into electricity. It is one of the renewable energy technologies being researched into, as part of solutions to the challenge of global warming and climate change. A major setback of this technology, however, is that it has a very low cycle efficiency. In this work a cogeneration cycle is proposed which is driven by the temperature difference between the warm surface layer and the cold bottom layer of the ocean. The work is aimed at improving the overall cycle efficiency of OTEC systems by reducing the depth at which cold water is captured from the ocean............
