In this thesis we study lower ramification numbers of power series tan- gent to the identity that are defined over fields of positive characteristics. Let f be such a series, then f has a fixed point at the origin and the corresponding lower ramification numbers of f are then, up to a constant, the multiplicity of zero as a fixed point of iterates of f. In this thesis we classify power series having ‘small’ ramification numbers. The results are then used to study ramification numbers of polynomials not tangent to the identity. We also state a few conjectures motivated by computer experiments t

The focus of this thesis paper is to study the impact the number of ants has on the found solution of the Ant Colony Optimization (ACO) metaheuristic when solving the Traveling Salesman Problem. The goal was to find out how the length of the computed tours change for different amounts of ants within a limited number of iterations. To study this, three well known versions of the ACO algorithm were implemented and tested: Min-Max Ant System (MMAS), Elitist Ant System (EliteAS) and Ranked Ant System (RankedAS). The results showed trends that were consistent over several test cases. EliteAS and Ra

This empirical study has shown that optimal portfolios need approximately 10 securities to diversify away the unsystematic risk. This challenges previous studies of randomly chosen portfolios which states that at least 30 securities are needed. The result of this study sheds light upon the difference in risk diversification between random portfolios and optimal portfolios and is a valuable contribution for investors. The study suggests that a major part of the unsystematic risk in a portfolio can be diversified away with fewer securities by using portfolio optimization. Individual investors es

Composite sampling terminology and theory are outlined and a model is developed which accounts for different sources of variation in compositing and data analysis. This model is used to define and understand the process of determining the optimum number of increments that should be used in forming a composite.

Currently, Europe has the best developed organic foods industry. Since 1986, Taiwan has undergone a developmental process of preparation, testing, demonstration, and promotion, with the result that there are now a large number of vendors producing and selling products to meet the homogenous market demand. For this reason, the market has now moved from its former monopoly market state to its current monopolistic competitive market state.

Traditionally, there are many ways to find one cut point to divide data into two groups. This paper will provide a method, when you need more than one cut point, you can correctly determine the optimal numbers of cut points and their locations. By multivariate Cox proportional hazard model and genetic algorithm , using the log-likelihood statistic as the criterion to determine the optimal cut points, and two-fold cross val

碩士<br>輔仁大學<br>應用統計學研究所<br>94<br>This paper discuss the queuing model with bulk service inder counting proceses and use loss function to value the optimal number id services. The Queuing model is based on counting processes. Assume the distribution of customers arrive indepentlly but the interval arrival time is not identical, it means that the rate of arrival cahnge with time. We define the model is λ(t) = θλ0(t) and consider some situtations such as poisson processes, linear medol and quadratic function. About the parameter , θ, we will use the property of weak converge of martingale central

Presently most bus operators use standard buses or use a singly type of bus to provide service. This leads some sections of the buses being overcrowded in peak periods and the load factor in the off-peak periods are low. Since using mixed types of buses were proposed in some previous researches, they only discussed a peak period of time or with many unsuitable assumptions. The optimal combination of

Cost of the duty over-cover or uncover piece-of-work and bus waiting for dispatching in the station are the most important subject that need to be solved. The optimal number bus is a medium-term decision. It limited the system capacity that can serve customers, should be solved with bus scheduling. The freeway bus scheduling is a problem of short-term decision, and problem solving itself has very big pressure of the time limited. When there is a bu
