Abstract: Life insurance is one of the important insurance type since death is an inevitable and unpredictablefor us. Also, the life of a person may depend on lives of others financially. Life insurance is a protection against financial loss if insured dies. Therefore, life insurance is significant type ofinsurance. In this presentation, we will briefly define life insurance then explain the nature of life insurance and discuss life insurance in Turkey.

Abstract: People have been trying to communicate with each other and hide the information which are believed to be kept as secret from the third parties by the help of the predecided ciphers. In the modern age, which is called as the age of information, ciphers have a great importance both in the areas of finance and military. States spend money in order to acquire the information and to keep them confidential. Finance institutions spend money to keep the personal informations of their clients. In this presentation, historical development of cryptograpghy will be examined.

Abstract. We use Markov risk measures to formulate a risk averse version of the total cost problem for a controlled Markov process. We derive conditions for a system to have finite risk over an infinite time horizon, and derive risk-averse dynamic programming equations satisfied by the optimal policy. We further  ropose an epsilon-optimal approximation to the optimal policy.

Abstract:The individual pension system is an alternative in solving social security system’s problems and it has seen as voluntary or a complementary tool of Social Security System. The individual pension system which is the first step of transferring private companies from community was seen in 1980. This study, using some data, firstly examines what individual pension system is and why society needs go into this system. When we look at the purposes of the private pension system, it can be easily understood that why this system is needed. Moreover, all over the world, private pension schemes have reached higher proportions in social security systems with the applications of its steps. In addition to these, in the light of the advantages, disadvantages and the problems faced by system, it is analyzed the effects of private pension system to financial market and economy.

Abstract: HFT is a program trading platform that uses powerful computers to transect a large number of orders at very fast speeds. It uses complex algorithms to analyze multiple markets and execute orders based on market conditions. This study involves the benefits and critiques of HFT, its strategies used by traders recently, and assets that we can use with it. And also what do a high frequency trader need to do her/his job.

Abstract: A high-quality extensive database is very critical to the gas turbine industry for improving the capabilities of the current state-of-the-art design of these machines so that more efficient cooled designs with extended turbine life can be accomplished. A series of experiments was performed at the OSU Gas Turbine Laboratory involving a rotating rig with a cooled 1-1/2 stage high-pressure transonic turbine operating at design corrected conditions with the goal of providing the turbine designer with such high-quality data. The turbine stage used is a modern 3-D design consisting of a cooled high-pressure vane, an uncooled high-pressure rotor, and a low-pressure vane. The work investigates the influence of different vane inlet temperature profiles and cooling flow rates on heat transfer of the full-stage turbine. A novel application of a traditional statistical method is introduced to the analysis to assign confidence limits to measurements in the absence of repeat runs. This approach is later incorporated into a CFD validation effort for blade heat transfer predictions in order to quantify the overall predictive uncertainty due to the variation in the inlet temperature profile, gauge position, and surface roughness. Presented data analysis highlights important turbine flow regions that are highly complex and are still not well understood today

Abstract: Copula method is a very popular topic in finance recently. This method is used to measure dependency between stock markets and commodities, stock markets and macroeconomic news, etc. Studying with non-linear models and non-Gaussian distributions, copula gives very useful results in financial markets. In this presentation, Copula function is defined and compared with other dependency measuring methods. To measure correlation there are two
different approaches: Top-Down and Bottom-Up Approaches. Copula function uses a Bottom-Up Approach. Advantages and disadvantages of the method are stated as well. In addition to theoretical discussion, very basic formulation and rules of Copula are provided.

Abstract: In today’s Financial Markets, investors need different type of financial instruments that satisfy their needs and expectations. For the very reason Exotic Options are substantial aspect in today’s world of trading . An Exotic Option is an option that differs in structure from common American and European Type Options in terms of the underlying asset, or the calculation of how or when the investor receives a certain payoff. In this meeting I will introduce important types of exotic options, their payoff structures and also in which circumstances we need that type of exotic option agreement.
