1. Secure image transferring using asymmetric crypto system

Nowadays, with the growth of technology, security is an important issue in communication. In many applications, the transmission of data (massage, image and so on) is needed to provide security against from preventing unauthorized users. Cryptography is a technique that provides secure communication. The two widely accepted and used cryptographic methods are symmetric and asymmetric. There are so many different techniques that should be used to protect confidential image data from unauthorized access. This system provides secure image transmission between the sender and receiver. This system uses Optimal Asymmetric Encryption Padding (OAEP) with an RSA encryption algorithm to provide security during transmission. Only public key cryptography is focused here. The public-key cryptographic algorithm relies on one key for encryption and a different but related key for decryption. In this system, different image formats (jpg, png, gif, and bmp) are used to test for encryption and decryption processes.

2. Automatic template logo segmentation and recognition of vehicles

An automatic system for vehicle and traffic control is essential for concessive increasing car usage. There are numerous numbers of application systems for a car number plate recognition system. But to recognize the car, it needs to consider other kinds of attributes such as car color and logo to avoid the fake license. This system tends to segment the car logo or trademark and then the segmented logo is classified. It implemented using the frontal image of Vehicles and it will be tested the car which is used in Myanmar. The metallic part is segmented from the front view of Vehicle by using region growing method in the reduction of searching space. The bounding box is defined according to the segmented metallic part. After that the logo localization via bounding box, it is segmented using morphological operators such as opening, closing, dilation, and erosion. The segmented logo is recognized by using the Template Matching Method using correlation coefficients.

6. The black hole battery

Astrophysicists presume that most black holes are created when massive stars (at any rate 8-10 times the Sun's mass) arrive at the end of their lifecycle. Inside a star, gravity attempts to force matter closer together. While a star is gleaming, it is devouring its fuel through an atomic procedure known as combination. It emanates light, however heat too. The weight of the warmed gases pushing outward adjusts the power of gravity pulling internal. When the star's atomic fuel has been drained, the star ends up temperamental and the center implodes making the external shell detonate in a supernova. On the off chance that the leftover center that remaining parts after the supernova is under 3 sun based masses, gravity packs the electrons and protons with the goal that neutrons structure. The weight of neutrons in contact with one another balances the powers of gravity. This steady center, which is presently made for the most part out of neutrons, shapes a neutron star. Neutron stars have gigantic mass and therefore have a ground-breaking gravitational force. On the off chance that the remainder left after the supernova is more prominent than multiple times the Sun's mass, not in any case the neutron weight can balance gravity and the staying material will keep on contracting. The remainder crumples to the point of basically zero volume (yet it has interminable thickness!). This makes a numerical peculiarity. A peculiarity lives in the focal point of every single black hole. A round district known as the occasion skyline marks what researchers call the "limit" of a black hole. It is given this name since data about occasions which happen inside this locale can never contact us. The good ways from the peculiarity to the occasion skyline is known as the Schwarzschild range, after the German physicist who anticipated the presence of an "enchantment circle" around a thick article. Inside the locale, he estimated, gravity would be amazing to such an extent that nothing could escape from it, i.e., the gravitational draw would be solid to such an extent that the speed important to get away from the force is hopeless. A black hole has such a huge convergence of mass in such a little volume, that so as to escape from it, an article would need to move at a speed more prominent than the speed of light. Right now we are aware of nothing that can accomplish the important speed. 2 Remember that an excellent black hole was at one time a star. Most stars have a partner star to which they are bound in a double framework. This close by friend can be a wellspring of material on which the black hole "bolsters". Matter can be pulled off the partner in huge twirling floods of hot gas that winding toward the black hole as a quick moving radiant whirlpool known as a gradual addition plate. As the issue in the plate falls nearer to the black hole, it warms up and emits radiation, for example, X-beams. By estimating the movement and radiation from a growth circle, space experts can gather the nearness and mass of the black hole. At the point when the majority of the material in the growth circle has been expended, the plate vanishes and the black hole is practically imperceptible. Stars and planets at a protected good ways from the black hole's occasion skyline won't be pulled in toward the black hole. They will rather circle the black hole similarly as the planets circle the Sun in our nearby planetary group. The gravitational power on stars and planets circling a black hole is equivalent to when the black hole was a typical star. 1.1 Supermassive Black Holes Supermassive black holes have masses tantamount to those of a small galaxy. These masses run somewhere in the range of 10 billion to 100 billion of our Suns. Supermassive black holes will in general be in the focuses of cosmic systems, making what are called Active Galactic Nuclei (AGNs). An AGN transmits more energy than would be normal from an ordinary galactic core. The appropriate response concerning why this is so lies within the sight of the supermassive black hole in the galactic focus. In some AGN, the massive black hole and its gradual addition circle by one way or another produce outward-moving surges of particles that are anticipated away opposite to the plate. These streams are known as planes and have the ability to quicken electrons nearly to the speed of light. This produces gammarays that can be distinguished by gamma-beam observatories. The most dominant AGNs in our Universe are called quasars. We have had the option to distinguish quasars that dwell 15 billion lightyears away. Researchers accept that the investigation of quasars will give data about the Universe during the hour of early cosmic system arrangement.

7. Operations Research in financial markets

“OR utilizes the planned approach and an interdisciplinary team in order to represent complex functional relationships as mathematical models for the purpose of providing a quantitative analysis’’ -Thieraub and Klekamp In the research paper, the overview of the industry for two years has been provided along with the research objectives as to what our main task was, what areas are focused on and what all the issues are as well as the steps taken to avert those issues. Operation research (OR) plays a crucial role in evaluating certain financial issues such as foreign exchange market, securities development, market regulations, debt, etc. OR helps in solving these problems and provides a proper solution to it. The research done on the financial market has provided us with various inputs as to when an investment should be made and when the investment should be sold off so as to earn or reap the maximum benefits out of it. The financial market is very vulnerable to any changes and hence, people need to keep a very close and frequent watch of it. People need a deep understanding of the financial market to act in it and is not an area of a layman. Basics also work when it is related with small scale transactions but when it comes to the large investments, it is always advisable to take help of an expert. For efficient solving of problems, OR techniques that were used twenty years ago such as statistical analysis, Linear Programming Forecasting, and Simulation were followed. Apart from these, some other problems which could be solved through OR were funding decisions.

8. Declining crude oil prices and its implications on the indian economy

The following research paper aims to study the implications of oil prices on the Indian economy especially the impact of declining prices. Oil prices are highly important for the economy especially a developing country like India. India is the 3rd largest energy and oil consumer in the world after China and the US. Oil is a factor that helps an economy to move forward and achieve high levels of growth. The research paper studies the oil production and the supply of oil. This paper has tried to estimate using various tools a correlation between oil prices and various economic and market factors. The paper studies the impact on various leading and lagging indicators in the economy that help give an idea about the implications of declining oil price on the economy. This research entails a study of economic factors like inflation, GDP, the impact on foreign reserves, etc. India depends highly on oil imports and thus an intensive study is required to understand the impact of the oil prices. Major imports for India come from Iraq and Saudi Arabia and the demand for oil in India is on the rise with every coming year. This Research has helped us conclude that Oil prices have an inverse relation with stock prices which means declining oil process have a positive impact on the stock prices and thus the economy. It is observed statistically that the role of inflation is significant in declining GDP growth of Indian economy. The two variables of oil prices and GDP of India are negatively correlated. This can explained by the fact that increase in oil prices lead to greater inflation, lower profits of firms, lower tax revenues for the government, higher current account deficit and dampened investor sentiment. All this factors restrict the economy from growing at its full potential.

9. Management of a rare case of spontaneous meckel’s diverticular perforation in an old age patient presented in the emergency room

Introduction: Meckel's diverticulum is the commonest congenital abnormality of the gastrointestinal tract. Haemorrhage, obstruction and inflammation are the three main categories of complications resulting from Meckel's diverticulum. Spontaneously perforation of Meckel's diverticulum is very rare and mimics acute appendicitis. Case: 50yr old male patient presented to the emergency room of our institute with abdominal pain for five days associated with fever with chills and complain of vomiting and anorexia. On the subsequent investigation it was found out to be a gastro-intestinal perforation. We operated the patient under general anaesthesia and intra-operative it was found out to be the Meckel’s diverticular perforation. So, we have done resection of contained part and done ileo-ileal anastomosis. Discussion: Meckel’s diverticulum is the result of dysgenesis of the small bowel as it develops in relation to the embryologic yolk sack and arises from the incomplete obliteration of the vitelline duct between the 5th and 8th weeks of gestation. Perforation is an uncommon complication of MD, and the symptom can mimic other acute abdominal conditions such as acute appendicitis as well as gynaecological and urological condition while in the emergency space. We should take diagnosis under consideration as a differential diagnosis when we encounter patients whose impression was firstly acute appendicitis and treatment should be followed accordingly.
