Research ArticleOpen accessIn the abstractMPLS over Segmented WDM Optical Packet Switching NetworksHakim Mellah, Fouad M. AbbouWavelength Division Multiplexing (WDM) is a promising solution for data transport in future all-optical wide area networks. Such networks consist of fibers joined by dynamically controllable cross-connects which provide purely optical transport between pairs of network access stations. Optical packet switching (OPS) is optical switching with the finest granularity. Incoming packets are switched all-optically without being converted to electrical signal. … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,754 accessesView PDFCite
Research ArticleOpen accessIn the abstractDigital Hardware Implementation of a Neural System Used for Nonlinear Adaptive PredictionHassène Faiedh, Chokri Souani, Kholdoun Torki, Kamel BesbesNeural networks have been widely used for many applications in digital communications. They are able to give solutions to complex problems due to their nonlinear processing and their learning and generalization. Neural networks are one of the key technologies for the communication domain and accordingly a special effort may be expected to be paid to real time hardware implementation issues. … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 6,767 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Meaning of a Redundant Codon: There is Protein Folding Information in Nucleic Acids in Addition to the Genetic CodeJan C. Biro, Josephine M.K. BiroAll the information necessary for protein folding is supposed to be present in the amino acid sequence. It is still not possible to provide specific ab initio structure predictions by bioinformatical methods. It is suspected that additional folding information is present in protein coding nucleic acid sequences, which is not represented by the known genetic code. Nucleic acid subsequences comprising … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 1 · 31 Mar 2006 · 8,297 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurvival in the Current Healthcare Environment How Close Are We to Socialized Medicine?Eldo E. FrezzaIn the 1980's, some hospitals established internal agencies to regulate cash flow and capital expense. State agencies promoted the evolution of healthcare facilities into more business-like organizations. Attention to the following matters will reduce hospital costs: 1) prevent or reduce nosocomial infections; 2) treat diseases at a stage amenable to outpatient therapy; 3) obtain complete information about the policies of … …Journal of Social Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 6,693 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Evolutionary Fitness of Bounded Rationality: Heterogeneous Populations in Antagonistic InteractionsTassos PatokosConventional game theory assumes hyper-rational players, while evolutionary game theory abandons the assumption. This paper studies what happens when agents of both profiles co-exist and get engaged in a series of antagonistic interactions (the Hawk-Dove game). It is shown that if rational agents are perfectly informed as to the type of their opponent, they find it optimal to always be … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 1 Dec 2005 · 8,025 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Semantic Cache Management Method in Mobile DatabasesShengfei Shi, Jianzhong Li, Chaokun WangIn mobile database systems, caching is a crucial way to improve the performance because a new query can be partially answered locally when the client is continuously moving around. Semantic caching has been paid much attention in traditional database systems. However, the methods of semantic cache management proposed in those systems are not suitable for mobile computing environment. Moreover, although … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,882 accessesView PDFCite
Research ArticleOpen accessIn the abstractWillingness to Pay for Air Quality Improvements in Klang Valley MalaysiaRafia Afroz, Mohd N. Hassan, Muhamad Awang, Noor A. IbrahimThis research employed contingent valuation method (CVM) to estimate the willingness to pay (WTP) of the respondents to improve the air quality in Klang Valley. The samples were divided according to different question formats i.e. open ended(OE), dichotomous choice(DC) and payment card(PC). The objective of this study is to investigate the convergent validity of contingent valuation estimates by comparing the … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 9,001 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Stability of a Certain Class of Linear Time-Varying SystemsM. De la SenThis study firstly considers the exponential stability of unforced linear systems of slowly time-varying dynamics. Possible switchings of the system structure to unstable dynamics during certain finite time intervals are admitted. The maintenance of global exponential stability does not necessarily require at most a finite number of switchings in the dynamics while infinitely many switches can also lead to stability. … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Elliptic Function Arising from the Theta Functions and Dedekind's η-FunctionIsmet Yildiz, Neslihan UyanikIt's a reality that there is a relationship between the sigma function of Weierstrass and theta functions. An elliptic function can be set up using the theta functions just as it can be astablished with the help of sigma function of Weierstrass and two relations between the Dedekind's h-function and - theta function were established by the using characteristic values … …Journal of Mathematics and Statistics, Vol. 1, Issue 2 · 30 Jun 2005 · 6,367 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Relations among Characteristic Functions of Theta FunctionsIsmet Yildiz, Neslihan UyanikIn this study, using the characteristic values $\begin{bmatrix} \varepsilon\\ \varepsilon' \end{bmatrix} = \begin{bmatrix} 1\\ 1 \end{bmatrix}, \begin{bmatrix} 1\\ 0 \end{bmatrix}, \begin{bmatrix} 0\\ 1 \end{bmatrix}, \begin{bmatrix} 0\\ 0 \end{bmatrix} \pmod 2$ a theorem on the $\frac{1}{2^r}$ coefficients of periods of first order theta function according to the $(1,τ)$ period pair (for $r \in N^+$) is established. The following equalities are also … …Journal of Mathematics and Statistics, Vol. 1, Issue 2 · 30 Jun 2005 · 6,044 accessesView PDFCite
