The individual of population in standard self-adaptive evolutionary programming (EP) is composed as a pair of objective variable and strategy parameter. Therefore, EP must evolve both objective variable and strategy parameter. In standard evolutionary programming (CEP), these evolutions are implemented by mutation based on only Gaussian random number. On the other hand, fast evolutionary programming (FEP) uses Cauchy random number as evolution of objective variable and exponential evolutionary programming (EEP) uses exponential random number as evolution of objective variable. However, all of these EP (CEP, FEP and EEP) commonly uses Gaussian random number as evolution of strategy parameter. In this paper, we propose new EEP algorithm (NEP) which uses double exponential random number for both evolution of objective variable and strategy parameter. The experimental results show that this new algorithm (NEP) outperforms the existing CEP and FEP.

The authors created a Web-based integrated education support system that unified the data in the administrative system and the education system in a university. The purpose of the system was to make the administrative system and education system data that had previously been separated seamless, and to implement seamless access from inside and outside the university while maintaining security. Moreover, the authors emphasized the development of a portal site as a point of contact for the system. As a result of using software packages and existing technology for the other servers and databases, and making a policy of not changing the administrative system at all, the authors were able to create the system in a short period of 5 months. After the system was operational, preparation and review for class could be done at home, and evaluations of reports and final determinations of grades could be done from outside the university. This confirmed that the education system was effective. Finally, the authors looked at the trouble and performance problems that occurred involving local rules in the business department during operation, as well as countermeasures for them. © 2006 Wiley Periodicals, Inc.

In this paper, we capture the impact of an ARQ scheme in the MAC/LLC layer with a forward error-correcting code on upper-layer packet transmissions over a Markovian channel by examining the performance of a single service data unit which may be either a TCP segment or a UDP packet. We assume that the ACK/NACK delay of ARQ blocks belong to a single service data unit is less than the transmission period of each ARQ block. The performance measures of a single service data unit transmission are derived in terms of the transmission success and failure probabilities given a retransmission time-out value, retransmission timeout probability and the moments of transmission delay. Further, the queueing performance of a service data unit transmitter is also presented by varying average received signal-to-noise ratio, mobile velocity, number of ARQ blocks needed to transmit a single service data unit, number of retransmissions for each ARQ block and error-correcting capability applied to an ARQ block. From numerical examples, renegotiation between a serving base station and a mobile station is needed, when the mobile station is far from the serving base station in order that a service data unit is fragmented into a larger number of ARQ blocks in order to apply high error-correcting capability for each one

This paper presents a model which facilitates the allocation of spinning reserve in a power network which includes a large HVDC infeed. The basic area control model of the power system is developed and subsequently fine-tuned using a non-linear optimization procedure. The model is then used to evaluate the frequency control performance in the face of a known load forecast considering NERC performance standards

This paper presents an approach to resolve the problem of authoring and interchanging educational material, based on web services. Here we describe the ultimate goal, of reusing and interchanging freely adaptive eleaming material, shortly sketch previous solutions, showing their benefits but also limitations and then introduce our web-service based approach. Finally, we discuss the gains brought by our proposed solution. © 2006 IEEE.

Acoustic model adaptation using first-order linear prediction for reverberant speech

This paper describes a hands-free speech recognition technique based on acoustic model adaptation to reverberant speech. In hands-free speech recognition, the recognition accuracy is degraded by reverberation, since each segment of speech is affected by the reflection energy of the preceding segment. To compensate for the reflection signal we introduce a frame-by-frame adaptation method adding the reflection signal to the means of the acoustic model. The reflection signal is approximated by a first-order linear prediction from the observation signal at the preceding frame, and the linear prediction coefficient is estimated with a maximum likelihood method by using the EM algorithm, which maximizes the likelihood of the adaptation data. Its effectiveness is confirmed by word recognition experiments on reverberant speech. Copyright © 2006 The Institute of Electronics, information and Communication Engineers.

Formal methods offer the promise of significant improvement on quality and reliability of critical embedded software. B-Method is employed to develop general-service ballistic computer programs in the paper, each of which can be adapted to a family of service/weapon-specific ballistic computers. Based on the structuring mechanisms of B-method, a unified approach is proposed to systematically control the complexity of ballistic parameters in the process of type and operation refinement, and ultimately a series of high reliable, reusable, and scalable programs are produced. Experiences with the application of the method and tools are also discussed.

The OSGi provides a service platform which ensures the interoperability between heterogeneous technologies and various devices in home network environment. Nowadays, user access control is one of the core parts which should be cleared, but there are no concrete researches yet. So in this paper, we propose a supplemented authorization policy management framework based on RBAC (Role-Based Access Control) for user access control at home network environment in which the OSGi service platform is operated. The proposed access control framework improves effectiveness, assures privacy and provides convenience at the same time. In conclusion, we provide the base to implement the effective, safe, and convenient the OSGi service platform by proposing the new framework in authorization and user administration part.
