1. Analysis and performance evaluation of slender square fin geometry for application in electronics devices heat sink

This paper focuses on a development of a heat sink with slender square fins for the application of relay circuit cooling wherein the device shall be used to cool inline snatch relays that are used as circuit breakers in PLC boards. The geometrical layout and thermal analysis of the heat sink are discussed in this paper. The relay circuits need effective heat sinks in order to dissipate the hot side heat from the chip to the atmosphere. This encourages designing a heat sink in which heat transfer enhancement is carried out by designing of slender square fins with plain and skewed profile fins that have a three-layer concentric triangular layout. With this geometrical layout, the thermal analysis and heat transfer enhancement from plain and skewed profile fins configuration are carried out. Thus the study is focused on design development and testing of the heat sink with slender square fins that have a generic progressive transverse layout of fins. The surface area enhancement and cross flow heat dissipation is planned through the use of through skew in the direction normal to of air flow. The geometrical layout and thermal analysis of these fins are discussed in the paper. Fins to dissipate approximately 35 to 40 watt of energy to get a desired to bring about the cooling of the relay circuits.

5. Stock market prediction using machine learning

The basic tool aimed at increasing the rate of investor's interest in stock markets is by developing a vibrant application for analyzing and predicting stock market prices. In this report we explain, the development and implementation of a stock market price prediction application using a machine learning algorithm. In this report, we try to analyze existing and new methods of stock market prediction. We take three different approaches to solving the problem: Fundamental analysis, Technical Analysis and The application of Machine Learning. We found evidence in support of the weak form of the Efficient Market Hypothesis. We can use Fundamental Analysis and Machine Learning to guide an investor’s decisions. We demonstrate a common flaw in Technical Analysis methodology to show that it produces limited useful information. Based on our findings, algorithmic trading programs are developed and simulated using Quant. During the past few decades, various machine learning techniques have been applied to study the highly theoretical and speculative nature of the stock market by capturing and using repetitive patterns. Different companies use different types of analysis tools for forecasting and the main aim is the accuracy, with which they predict which set of stocks would yield the maximum amount of profit.

7. Video assisted teaching programme on first-aid for common medical emergencies

Adolescents are a period of curative madness in which every teenager has to remake his personality to free himself/herself from childhood, from parent and establish a new identity. Apart from the emotional and psychological independence, an adolescent has to deal with the ongoing physical and sexual changes in the body. He /she must have the intelligence to deal with external forces over which he/she has little control. Adolescents, mainly boys are very energetic at this stage and are prone to road accidents because of fast and negligent driving. They are at particular risk of violent deaths due to adventurous, great risk-taking and aggressive behavior. (Neelam Takur 2007) The goal of first aid is to save a life, prevent injury or illness from worsening or to help the speedy recovery. First aid and basic life support are so important to teach basic first aid and should be compulsory in all schools. Without any delay first aid saves a person’s life, it is always better as it is said that “Preparedness is a key element of first-aid”. The approach of the study was quantitative research with an evaluative approach. The study was conducted in Government High School Thirunanthikarai at Kulasekharam, Kanyakumari District. The population was Adolescents who are studying in classes of 8th and 9th standard (13-14 years). Purposive sampling technique was used. The sample size was 60 Adolescents in the age group. The tools used for data collection were demographic variables and structured knowledge questionnaire. The analysis revealed that there was a significant improvement in the mean knowledge.

8. Auto transplantation of a Mandibular Third Molar tooth with immediate root canal therapy: A Case series

Auto transplantation of teeth defines as the movement of a tooth from one place to another position within the same individual. It has been practiced for many years with varying degrees of success in the human race. Auto transplantation of teeth ensures maintenance of alveolar bone volume by physiological stimulation of the periodontal ligament. It requires long-term follow up of both clinical and radiographical evaluations. Auto transplantation includes transplantation of embedded, impacted or erupted teeth from one site into other extraction sites or surgically prepared site of the same person. Auto transplantation has been used to replace missing teeth and teeth with poor prognosis. In our study, we have used schinder’s root curvature analysis with immediate root canal therapy which is an additional tool for both endodontist and the oral surgeon. The newer technique of analyzing root curvature in both transplatation tooth and donor site had a great benefit for the success rate of our study. Root curvature analysis helped in both time management and planning of entire transplantation procedure. Radiographs evaluation showed readopted of periodontal tissue and successful masticatory function of the transplanted tooth.
