In this paper we present a new technique to obtain estimators for parameters of ergodic processes. When a diffusion is ergodic its transition density converges to the invariant density [1]. This convergence enabled us to introduce a sample partitioning technique that gives, in each sub-sample, observations that can be treated as independent and identically distributed. Within this framework, is...

The problem of regulating the biomass growth rate at its maximum value in an open-loop unstable, continuous, non-monotonic biological reactor using biomass measurement and manipulation of substrate feed rate is considered. An Output-Feedback controller is designed exploiting the reactor open-loop stability and inherent observability properties and the relative degree structure to obtain robust ...

We study a problem that is the "inverse" of Merton (1971). For a given consumption-portfolio policy, we provide necessary and sufficient conditions for it to be optimal for "some" agent with an increasing, strictly concave, time-additive, and state independent utility function when the risky asset price follows a general diffusion process. These conditions involve a set of consistency and state...

This paper addresses some lexical issues in the development of XUNL – a knowledge representation language descendent from and alternative to the Universal Networking Language (UNL). We present the current structure and the role of Universal Words (UW) in UNL and claim that the syntax and the semantics of UWs demand a thorough revision in order to accomplish the requirements of language, culture...

In this paper, firstly we propose two new concepts concerning the notion of key escrow encryption schemes: provable partiality and independency. Roughly speaking we say that a scheme has provable partiality if existing polynomial time algorithm for recovering the secret knowing escrowed information implies a polynomial time algorithm that can solve a well-known intractable problem. In addition,...

Most times the provision of e-government services is dealt with independency of the legacy system itself. As more complex transactional services are provided to the public and the degree of on-line interaction between e-government service users (Internet) and legacy system users (Intranet) increases, the integration between e-service provision platform and existing legacy information system bec...

The metamodeling platform ADONIS has originally been implemented for the use in business process management. Its method independency and extensive customization functionalities also allow for the application in many different other areas such as strategic management, e-learning, object-oriented systems engineering, knowledge management, and numerous others. In computer science the Unified Model...

To confirm the language independency of a communicative prosody generation from input word impression vector, we synthesized communicative Mandarin speech using prosodic characteristics of communicative Japanese speech. The fundamental frequency and duration characteristics of oneword “n” utterances of Japanese were copied to Mandarin through input word attributes. From the subjective impressio...

Systematic application of software metric techniques can lead to significant improvements of the quality of a final software product. However, there is still the evident lack of wider utilization of software metrics techniques and tools due to many reasons. In this paper we investigate some limitations of contemporary software metrics tools and then propose construction of a new tool that would...

This paper proposes causal models to enhance the performance analysis of parallel processing. Causal models explicitly denote the relations among the variables involved. This makes it possible to automate the modeling task as well as to present the user a clear and understandable performance analysis. It is a flexible approach, since new environment variables can easily be integrated and perfor...
