Code-Switching in the University Level Students of Bangladesh: An Empirical Study

The motto of this research article is to present how Bangladeshi University students use the mixture of both English and Bengali language as their spoken language. It can be said undoubtedly that English is the vast spoken language in the whole world as well as spreading to a large extent. Bangladesh is not different from other countries as well as English has been taught every level an every medium of education here and in recent times it is seen that English is used by the university students when they talk with each other I mean we can see a mixture of two languages. Each language has a social function which no other language could possibly fulfill (Hudson, 1996). Perhaps that is why code switching has become a common phenomenon in our everyday conversations in the recent years in Bangladesh. Young people randomly style switch in their daily interactions. This research paper also explores the possible propelling factors as well as stereotypical patterns behind this scenario. The data collected for the study reveals different factors as the causes behind this practice of code-switching and its impact on language behavior

Effect of material properties on ductility factor of singly rc beam sections

Ductility may be defined as the ability to undergo deformations without a substantial reduction in the flexural capacity of the member. The ductility of reinforced concrete beams depends mainly on the shape of the moment-curvature relationship of the sections. The constituents of reinforced concrete are very complex due to its mechanical properties. The stress-strain behavior of concrete is considered parabolic and that of the steel is elastic plastic. Concrete and reinforcing steel are represented by separate material models that are combined together to describe the behavior of the reinforced concrete sections. The end displacements of the steel element are assumed to be compatible with the boundary displacements of the concrete element which implied perfect bond between them. The curvature ductility factor of singly reinforced concrete rectangular beams is derived taking into account the possible nonlinear behavior of the unconfined compressed concrete and reinforcing steel. Effects of material properties such as concrete compressive strength, reinforcement ratio and yield strength of reinforcement on the curvature ductility factors are derived analytically. From the analyses it is observed that an increasing steel content decreases the curvature ductility of a singly reinforced concrete section and this pattern is valid for any concrete strength. On the other hand, for the same reinforcement content curvature ductility increases as the concrete strength is increased

The Role of Educational Technology in the ESL Classroom

The use of technology has become an important part of the learning process in and out of the class. Technology continues to grow in importance as a tool to help teachers facilitate language learning for their learners. This study focuses on the role of using new technologies in learning English as a second/foreign language. It discussed different attitudes which support English language learners to increase their learning skills through using technologies. In this paper, the researcher defined the term technology and technology integration, explained the use of technology in language classroom, reviewed previous studies on using technologies in improving language learning skills, and stated certain recommendations for the better use of these technologies, which assist learners in improving their learning skills. The literature review indicated that the effective use of new technologies improves learners’ language learning skills

Removal Of Blocking Artifacts From JPEG-Compressed Images Using Neural Network

The goal of this research was to develop a neural network that will produce considerable improvement in the quality of JPEG compressed images, irrespective of compression level present in the images. In order to develop a computationally efficient algorithm for reducing blocky and Gibbs oscillation artifacts from JPEG compressed images, we integrated artificial intelligence to remove blocky and Gibbs oscillation artifacts. In this approach, alpha blend filter [7] was used to post process JPEG compressed images to reduce noise and artifacts without losing image details. Here alpha blending was controlled by a limit factor that considers the amount of compression present, and any local information derived from Prewitt filter application in the input JPEG image. The outcome of modified alpha blend was improved by a trained neural network and compared with various other published works [7][9][11][14][20][23][30][32][33][35][37] where authors used post compression filtering methods

Self-synchronized converter for fast synchronization between low voltage microgrid and inverter connection

In this research, a fast-synchronization between single-phase microgrid and inverter in low voltage, which is based on virtual synchronous converter (VSCon) technique is been developed. This technique does not require any phase locked loop (PLL) circuit as an external control structure for the synchronization of the inverter. As known, PLL is a common technique in order to synchronize the amplitude, phase-angle and frequency between a microgrid and an inverter in distributed generation network. Previous studies show that, the disadvantage of PLLs is where the non-linear characteristic on the signal process will result the inverter control to be non-linear. Therefore, it is difficult and lengthy process to tune the PLL gains to reach suitable performance in order to synchronize the voltage, phase-angle and frequency between microgrid and inverter. As a result, a VSCon is been developed in which it is a self-synchronized inverter which is based on synchronous generator mathematical model. This controller acts like as synchronous generator operating system in inverter control loop in order to achieve fast voltage, phase and frequency synchronization between inverter-microgrid connection. This technique has been modeled, simulated and tested in Matlab/Simulink software. It is by using a single-phase AC source input system connecting with several load variations during simulation period. This VSCon has been placed in inverter control loop to generate a pulse width modulation (PWM) signal that responds to the grid information for to synchronizing the inverter output voltage with the grid voltage. A single source input at 120V, 50Hz frequency and 240V, 50Hz frequency are used in order to see the self-synchronization response between a microgrid and an inverter. Furthermore, it also been tested when the grid frequency has been changed from the rated frequency at 50Hz to 51Hz and the result shows that, VSCon takes nearly 1-cycle to synchronize to this new frequency value. The grid phase angle test also has been conducted. For this test, the voltage grid which has 100 phase delay has been created in the input voltage source at microgrid side. As a result, the VSCon is also able to achieve self-synchronization with this new sourc

A REPORT OF GEOGRAPHICAL ENVIRONMENT AROUND MANAHARPUR VILLAGE IN BAKRESWAR, BIRBHUM DISTRICT

Manaharpur is a small village located at a distance of about 2 kms. to the east of the Bakreswar Thermal Power Plant in the district of Birbhm. Originally this village was located on the land where the present thermal power plant has now been established along with others. When the Power project was commissioned in 1992 all the villages which fell in the selected site of the project had to be removed from the area and the villagers of Manaharpur were given refuge at its present location. With some financial assistance the villagers rebuilt this village a few kilometres to the east away from the existing power plant site
