1. Myanmar Word Sense Disambiguation based on HMM

In natural language processing, word sense disambiguation (WSD) is the problem of determining which "sense" (meaning) of a word is activated by the use of the word in a particular context, a process that appears to be largely unconscious in people. Nowadays, Word Sense Disambiguation (WSD) is an important technique for many natural language processing applications such as information retrieval and machine translation. Among them, the WSD technique is used for machine translation to find the correct sense of a word in a specific context. In machine translation, the input sentences in the source language are disambiguated in order to translate correctly in the target language which is Myanmar language that has many ambiguous words. Therefore, Hidden Markov Model-based WSD method is used to resolve the ambiguity of words in Myanmar language. A Myanmar-English bilingual corpus is used as the training data. This system can solve the semantic ambiguous problems that usually happen in Myanmar-to-English translation.

2. Calculation on the false assumption makes incorrect result

This paper is only for reviewing a formula using in a particular subject. We have known a false assumption is an assumption as a kind of logic fallacy. And we have also known that false assumptions would produce incorrect results. Incorrect results cause to be incorrect decisions. In this paper, we propose a little but important problem that calculating on a false assumption of total communication time for distributed query processing within the distributed database environment. To understand our paper, we must first explain the basic knowledge of a distributed database system. A distributed database system consists of a collection of sites, connected together via some kind of communication network. In the distributed query processing there is two or more sites that may be included. The primary objective in distributed systems is to minimize the number and volume of messages between the participant sites. There will be many possible ways of moving data around the system to satisfy the request. To minimize the network utilization, it is important that an efficient strategy be found. There may be many possible strategies for processing the request. To evaluate which strategy is to be efficient, we will calculate the total communication time for each strategy by using the formula. The choice of the best strategy is based on the result of we calculated. So, if we must have the correct answer, then we can make the correct choice. In this paper, we will apply a formula that is teaching now in our university to calculate the total communication time. We would like to present our paper with two aspects, one is ‘the false assumption on the formula that we used’ and the second is ‘suggested for that formula with another view’.

3. The Third Eye

As technology is increasing day by day, technology for visually impaired people is also increasing at a fast pace, but having some things that make their life easier and things that they use daily to complete tasks are the absolute best. Here we have presented an application for a blind person or visually impaired people so that he/she can access the basic functionality of a smartphone. WHO (World Health Organization) report states that approximately 285 million are visually impaired in the world. They face challenges like communicating with the world in their day-to-day life. It creates difficulty in their life even to make a phone call and access other functionalities of a smartphone. After so much advancement still, some people are not able to use a smartphone. With the expeditious growth of wireless communications, voice recognition technique has increasingly needed. A gesture-based application helps a wide range of users to operate a smartphone. This application listens to gestures, speech and performs relevant action.

4. Design calculation of Kaplan Turbine Runner Blade for 15kw Micro Hydropower Plant

This paper deals with the design of the runner blade profile for Kaplan Turbine. The world has a huge potential for small hydro Kaplan turbine power plants. The world energy demands are increasing. In this micro-hydro, Kaplan power plants gain special attention. The development of micro-hydro Kaplan power plants on a large scale will generate enough energy for the world inhabitants. This paper presents the runner of a low head Kaplan turbine in which the net head and rated flow of water are 2.4m and 0.8 m^3/s respectively. The turbine is single regulated Kaplan turbine with runner diameter 560 mm, hub diameter is 220 mm, and net power capacity is 15 kW. Major component of Kaplan turbine are spiral casing, guide vane mechanism, and runner.

5. Study of utilization of concrete wastewater and treatment system

The purpose of this study is the examination of the properties of wastewater obtained from a ready-mixed concrete plant and its utilization potential as mixing water for concrete production of the batching plant from the Great Wall industry, Sagaing Division, Myanmar. The fact that wastewater has a detrimental effect on the durability of concrete structures is not disputable. The efficient water is one of the most important acquirements of cleaner production and the use of wastewater in concrete production important means to this end. Samples of wastewater from several points of a water recycling process from this ready-mixed concrete plant were examined for their chemical properties (CI; SO42 -, alkalis, total solids, pH) and compared with the specifications applied for concrete mixing water. Also, samples of dry sludge powder form the water-recycling process tank were taken and tested for their chemical composition, particle size distribution, and mineralogical composition and thermo gravimetrical results. The water samples were examined for their behavior in concrete specimens with and without admixtures and also for their effect in water demand and setting times in cement pastes. This paper reviews the degradation mechanism of wastewater on ready-mixed concrete structures with a view to finding what needs to be done to salvage these structures. It is obvious that the results of this investigation contribute to the protection of the environment from hazardous wastewater disposal and the ready-mixed concrete industry from freshwater costs and any additional cost for buying and conserving an unnecessary complicated water-recycling system.

6. Interactive tutorial framework for online learning

Nowadays, online learning, teaching and online tutorial have become popular as higher education. Online learning is the delivery of learning, training or educational program according to the electronic means. So, this system is intended to develop an interactive tutorial website for online learners. A web based tutorial is a complete program whose purpose is to assist users in learning. It is a method of transferring knowledge, interactive set of instructions to teach by example. The online tutorial framework is the technique of representing a small kind of exam by a computer program. So, this system will examine the student study level by answering the random comprehensive questions. This system enhances the quality and improves the accessibility within education domain.

7. Psychological capital and psycho-ecological schemata in crisis intervention

The testing times of crisis tend to churn the psychosocial, socioeconomic, anthropometric, geographical, political, cultural, and the entire fabric of mankind. While, some individuals and their “psycho-ecological systems fall prey to the vicissitudes of crisis; on the other hand, there are other patches of populations and civilizations that cross-cut through those testing times and return to normalcy with a new approach towards life. The present research is a quantitative and qualitative attempt to carve out the crisis intervention methods that enhance the psychological capital and facilitate psycho-ecological schemata of individuals. More specifically, the present research delves deeper into the aspects in the light of the COVID-19 worldwide pandemic. Findings of the research indicate towards a significant positive difference and changes in psychological capital of the research subjects at both p< .05 and p< .01 level of confidence; stating that appropriate, timely and relevant Crisis Intervention foster hope, resilience, optimism, and self-esteem as part of positive psychological capital of the individuals and their psycho-ecological schemata as well.
