Determination of Dispersivity in A Laboratory Soil Column

In this study, a laboratory soil column experiment was carried out for estimating the dispersivity (?) in sandy loam soil by the inversion of the Advection-Dispersion Equation. An 89 cm deep and 15 cm diameter cylindrical column was filled with sandy loam soil in such a way that the bulk density of the soil in field condition was strictly satisfied in the column. Potassium bromide was used as the conservative tracer in the study. 

The tracer concentration was allowed to pass through the column at a constant rate and the leachate collected at different time periods were tested for the concentration of bromide. The experiment was carried out until the relative concentration (c/c0) has reached 1. The calculated relative concentration was plotted against time for obtaining the observed breakthrough curve (BTC). 

Another BTC was plotted using the analytical solution of Advection Dispersion Equation. The effective dispersion coefficient (De)value which gave the best fit between these two curves was chosen by trial and error method and the dispersivity of the soil was calculated (De = ?v)for a constant pore water velocity (v). The dispersivity of the sandy loam soil under study was found to be 1.7 cm which matches well with the previous researches.

Guidelines for Approching Steps of Learning Programmable Logic Controllers in Automation

This paper provides both Theory and Practical of Programmable logic controller (PLC) in Automation engineering. According to various manufacturing company, the nature and useful area of PLC may be different and this paper mainly supports step by step approaching methods to be familiar with what is PLC and how PLC work. Automation purpose is the main application of PLC and the programmers or control supervisors will be able to learn easily with the four levels or steps that perform in this paper.

Simulation Approach with MATLAB GUI for Teaching Electronic Engineering Subjects

The four main core of undergraduate electronic engineering course can be considered as Electronics, Computer Application, Control and Communication. The objective of this research was the development of software approaches in teaching undergraduate Electronic Engineering Candidates to cover the practice of what and how Electronics, Computer Application, Control and Communication processes are going on. This paper describes a simple computer-aided design approach for analysis of various system related to electronic engineering. 

The GUI design of this paper is mainly focus on teaching electronic circuits analysis, control system analysis and RFID antenna design. The simulation program for creating a GUI that linking sub-program of each fields is developed using Matlab GUI. This paper is just a portion of the research 'œDesign and Development of Easysuit Software Approaches for Electronic Engineering Subjects using Matlab'. All performance result of a sample GUI program that students can use to analyse the behavior of circuits, control and communication systems.

Performance and Emission Characteristics of Biodiesel From Algae in A Diesel Engine

Rapid industrialization and growth in population has resulted in the rapid increase in energy demand. Indiscriminate use of fossil fuels has led to extinction of petroleum sources. Pollutant emissions from diesel engines has caused major impacts in disturbing the ecological system. To overcome these problems, focus is towards alternative sources. Biodiesel, derived from vegetable oils, animal fats and algae is the future prospect. The paper reviews the research on impact of biodiesel on performance. 

Fuel properties like calorific value, flash point and cetane value of biodiesel and biodiesel blends(B5,B15,B25) were found comparable petroleum diesel. Performance results reveal that most of the biodiesel, give higher brake thermal efficiency and lower brake -specific fuel consumption

Internet of Things (Iot) Based Smart Environment and its Applications

In day to day world the internet of things is one of the emerging technologies. Through wired and wireless medium IOT connects various object which helps the human to interact with objects in both digital as well as physical world. Due to increase of population the services are very challenging for the providers. To overcome those challenges the IOT has developed with many applications. IOT contain the sensor which connects to Bluetooth, Wi-Fi, RFID and also it covers wide area with many technologies like GSM, 3G and GPRS. The IOT devices collect many useful information from various devices and flow the data between many devices. 

The flow of information can be done without human'“to-human or human'“to-computer interaction. Due to IOT the world will become smart so it is called as smart home, smart cities, smart building and also some applications. Many sectors are connected to RFID technologies like banking, agriculture, education, domestic appliances monitoring, Surveillances, government '“ e services, government '“ e services, traffic surveillance, meteorology and security and emergency. This devices also consist of heat, light, security system with less cost. 

The online capable devices figure was 31% in 2016. It increased up to 8.4 billion in 2017. The IOT devices will be increased more than 30 billion in the year of 2020. The value of IOT will reach nearly up to $7.1 trillion. In 2019 Enterprise internet of things (EIOT) devices increases up to 9.1 billion. In this paper IOT based smart environment is discussed with its issue. It is used for transport, vehicle parking, waste management, reduce traffic, increase the better communication with road side objects like hospital, school and also with other objects.

Power Conversion Interface

The global environment is degrading and all efforts are being made to reverse the situation. Power generation based on fossil fuel is partly responsible for the polluting emissions. Because of this, renewable (non-pollutant) energy sources have received a lot of attention in the power community. The cost of renewable energies is expected to fall as the demand increases. Power conversion interfaces (PEI) are needed to integrate renewable energy sources with the existing electrical power system. This paper provides a brief introduction on power conversion interfaces.

The Comparative Study on Improvement of Tender Systems in Myanmar

The purpose of this paper is to improve the different types of only public tender systems and contract systems in Myanmar. The study is divided into two parts. The first one is comparing the tender systems and the second is comparing the contract systems. Firstly, tender systems of each ministry are studied. When studying the existing practices of tender systems in Myanmar, there are many deficiencies in each ministry and they are unsystematic. To improve the tender system that is different and has defects, tender systems of each ministry are compared. A better and suitable tender system is defined from comparing each ministry. 

Then that better and suitable tender system is compared with American Institute of Architect (AIA). The suitable facts for Myanmar and the key factors or components that should involve are taken into account. And then the improved tender system that is more suitable and perfect gets. Secondly, contract systems of each ministry are studied. The bid phase has defects for making contract after awarding the tender. There are many problems in current existing contract bid because of weakness and difference of bid phase. To solve them, an improved contract system that should include the suitable facts for each contract investigate and constructs for Myanmar.
