Jörg Eberspächer Master’s Thesis Parameter Optimization for 3G Cellular Networks Author: Matriculation Number: Address: Email Address: Supervisors: Begin: End: TOH, Kok Liang 2706603 Felsennelkenanger 7, App S402 80937 München Deutschland tk_liang@hotmail.com Mr. Roger Abou Jaoude (LKN) Dr.-Ing. Christian Hartmann (LKN) 01. April 2006 01. October 2006 ii Abstract Parameter optimization, such as antenna tilting and CPICH power, can be used to adapt the traffic capacity of 3G systems to traffic demands which are varying in the space and time dimensions. The goal of this thesis is to investigate how parameter optimization can be implemented, both in the 3G cellular system’s initial planning stage to optimize the network for CAPEX saving as well as after the deployment of the network, to increase the capacity of the system. For this purpose, appropriate models, including the space and time domain dynamics of the traffic modeling the moving hotspot characteristics, have been integrated into a system simulation tool. Meta-heuristics techniques such as Tabu Search and Simulated Annealing have been implemented to solve this NP-hard problem. Results show that the existence of optimal configurations can have an achievable capacity gain of more than 30%. iii Acknowledgements This Master Thesis would not have been possible without the support of many people. I would like to express...

( Appendix 9). Semi Interquartile range(SIR) called Quartile deviation defined as the difference between first and third quartiles and divided by two (Appendix 10) SIR is often used with skewed data as it is insensitive to the extreme scores.

...Does Saving really matter for Growth in Developing Countries? The Case of a Small Open Economy Olajide S. Oladipo, PhD Department of Economics and Finance School of Business, Medgar Evers College 1637 Bedford Avenue, Brooklyn, NY 11225 Email: ooladipo@ mec.cuny.edu Abstract The study employed the Toda and Yamamoto (1995) and Dolado and Lutkepohl (1996) – TYDL- methodology to uncover the direction of causal relationship between savings and economic growth in Nigeria between 1970 and 2006. The empirical results suggest that savings and economic growth are positively cointegrated indicating a stable long run equilibrium relationship. Further, the findings revealed a unidirectional causality between savings and economic growth and the complementary role of FDI in growth. Keywords: Cointegration, FDI, Savings and Economic Growth JEL Classification: C32; E21;O11 Does Saving really matter for Growth in Developing Countries? The Case of a Small Open Economy Introduction The relationship between savings and economic growth has received increased attention in recent years especially in developed and emerging economies [see Bacha (1990), DeGregorio (1992), Levine and Renelt (1992), and Jappelli and Pagano (1994)]. This might not be unconnected to the central underpinning of Lewis’s (1955) traditional development theory that increasing savings would accelerate economic growth. Research efforts by Kaldor (1956) and Samuelson and Modigliani (1966) examined how different savings...

...Journal of Economic Literature Vol. XXXIV (March 1996), pp. 97-114 The Standard Error of Regressions By D E I R D R E N . M C C L O S K E Y and STEPHEN T. ZILIAK University of Iowa Suggestions by two anonymous and patient referees greatly improved the paper. Our thanks also to seminars at Clark, Iowa State, Harvard, Houston, Indiana, and Kansas State universities, at Williatns College, and at the universities of Virginia and Iowa. A colleague at Iowa, Calvin Siehert, was materially helpful. T cant for science or policy and yet be insignificant statistically, ignored by the less thoughtful researchers. In the 1930s Jerzy Neyman and Egon S. Pearson, and then more explicitly Abraham Wald, argued that actual investigations should depend on substantive not merely statistical significance. In 1933 Neyman and Pearson wrote of type I and type II errors: HE IDEA OF Statistical significance is old, as old as Cicero writing on forecasts (Cicero, De Divinatione, 1. xiii. 23). In 1773 Laplace used it to test whether comets came from outside the solar system (Elizabeth Scott 1953, p. 20). The first use of the very word "significance" in a statistical context seems to be John Venn's, in 1888, speaking of differences expressed in units of probable error; Is it more serious to convict an innocent man or to acquit a guilty? That will depend on the consequences of the error; is the punishment death or fine; what is the danger to the community of released...

THE SCOPE OF THE RESEARCH PAPER: It is a survey research paper presenting the results of the cost of capital survey of advisors, corporations etc showing a close alignment among the groups on the use of common theoretical framework and on many aspects of estimation. Variations are found on large number of joint choices regarding cost of capital. 2. INTRODUCTION TO THE TOPIC: The paper is about presenting evidence that how some of the most financially sophisticated companies and financial advisers estimate capital cost. The evidence to be presents is valuable in several aspects. First is to identify the most important ambiguities in the application of cost of capital theory and the second is helping interested companies benchmarking their cost of capital estimation practices against best practice peers. Third is that the evidence sheds light on the accuracy with which the capital costs can be reasonably estimated. The cost of capital can...

...market presents an 8 to 11 years cycle in price and production. Coffee market is well known for its volatility and for the crisis that producers are confronting, i.e., poverty, low prices, etc. The main causes for this crisis are the characteristic behaviors of the coffee market itself, which presents price instability, resource unsustainabillity, and inequity along the commodity chain (specially for coffee growers), the same characteristics of other commodity markets. In this paper we focused on the first of the causes, price instability, and so we created a System Dynamics model of the Colombian coffee sector that captures the structure of that market, the delays and feedbacks present on it. With this research we intended to answer the following questions: Why is the Colombian coffee market so unstable in price and quantity? And what can be done to reduce the instability of that market? The model is an adaptation of the generic structure, created by Meadows 1970 for commodity markets. We demonstrate that cycles in Colombia coffee sector can be endogenously generated and propose some policies that might contribute to dampen those oscillations. Key Words: Commodity cycles, Colombian Coffee Market, System Dynamics, Price Dynamics, and Coffee Crisis....

...Statistical Databases Jaideep Srivastava and Hung Q. Ngo, Department of Computer Science, University of Minnesota, 200 Union street, EE/CS Building, room 4-192, Minneapolis, MN 55455 e-mail: srivasta, hngo @cs.umn.edu, ¡ 1 Introduction A statistical database management system (SDBMS) is a database management system that can model, store and manipulate data in a manner well suited to the needs of users who want to perform statistical analyses on the data. Statistical databases have some special characteristics and requirements that are not supported by existing commercial database management systems. For example, while basic aggregation operations like SUM and AVG are part of SQL, there is no support for other commonly used operations like variance and co-variance. Such computations, as well as more advanced ones like regression and principal component analysis, are usually performed using statistical packages and libraries, such as SAS [1] and SPSS [2]. From the end user’s perspective, whether the statistical calculations are being performed in the database or in a statistical package can be quite transparent, especially from a functionality viewpoint. However, once the datasets to be analyzed grow beyond a certain size, the statistical package approach becomes infeasible, either due to its inability to handle large volumes of data, or the unacceptable computation times which make interactive analysis impossible. With the increasing sophistication of data collection instrumentation...
