This paper demonstrates a novel approach to determining the optimum guard interval for a multicarrier code division multiple access (MC-CDMA) system. Analytical expressions for useful and interference power are derived as a basis for comparison. From these, an expression for the signal-to-noise ratio of a detected bit is derived and used to determine the optimum guard interval for a given chann...

Most of the methods for video summarisation rely on complicated clustering algorithms that make them too computationally complex for real time applications. This paper presents an efficient approach for video summary generation that does not relay on complex clustering algorithms and does not require frame length as a parameter. The present scheme combines colour histogram and edge histogram fe...

The present study aimed to determine the optimum policy component in an example of potato cultivation development based on principle efficient use scarce resources and maximizing benefit producer. Agricultural support policies are commonly implemented by adopting a top-down approach. Regarding maximization at target group level, for agricultural products should be determined with bottom-up In t...

since the breakdown of the bretton woods system, exchange arrangements of countries have become flexible. several attempts have been made to determine whether the theories of optimum currency areas adequately explain the choice of an exchange rate system. in this paper, the optimum currency area is retested. using cross-section data, a regression analysis of the choice of an exchange rate syste...

Continuous state DEC-MDPs are critical for agent teams in domains involving resources such as time, but scaling them up is a significant challenge. To meet this challenge, we first introduce a novel continuous-time DEC-MDP model that exploits transition independence in domains with temporal constraints. More importantly, we present a new locally optimal algorithm called SPAC. Compared to the be...

A Manufacture Support System using Taguchi Methods was developed and evaluated. This system consists of a Taguchi methods part, a CAE simulation part and a management part of productivity. The Taguchi methods part was firstly used for calculating the average and the standard deviation regarding all combinations using all parameters. The CAE part was then used for shortening the total time of ev...

We present a multi-agent approach to constraint satisfaction where feedback and reinforcement are used in order to avoid local optima and, consequently, to improve the overall solution. Our approach, FeReRA, is based on the fact that an agent’s local best performance does not necessarily contribute to the system’s best performance. Thus, agents may be rewarded for improving the system’s perform...
