On the Information Engine of Circuit Design

This paper addresses a new approach to find a spectrum of information measures for the process of digital circuit synthesis. We consider the problem from the information engine point of view. The circuit synthesis as a whole and different steps of the design process (an example of decision diagram is given) are presented via such measurements as entropy, logical work and information vitality. We also introduce new information measures to provide better estimates of synthesis criteria. We show that the basic properties of information engine, such as the conservation law of information flow and the equilibrium law of information can be formulated.Comment: 4 pages, 1 figure, 2 tables, MWSCAS'0

Novel algorithm for enhancing database access in interactive applications: performance evaluation

Online applications rely heavily on database managementsystems (DBMS), as an essential component of knowledgediscovery. DBMS searching and querying has been extensivelystudied resulting in significant reduction of responsetime for access and consequently improving the online dialogueprocess between servers and clients. In this paper,a decision-making algorithm (SEQUESTER) has beendeveloped in order to further improve the performance ofinteraction-based online applications. The proposed approachuses information theoretic measures in order tobuild efficient decision trees which form the basis to optimizeinteractions in a range of real life online applications.The decision-making model employs a question-and-answer(Q&A) approach to guide users in an interactive process toexplore for information such as products in a database. Thesalient feature of this approach is the significant reductionof the number of interactions (accesses) of a customer to aremote application

Frequency of abdominal aortic calcification in a group of Iraqi hemodialysis patients

Cardiovascular complications including abdominal aortic calcification significantly affect the mortality and morbidity in patients on a hemodialysis (HD) program. The objective of this study is to find the frequency of abdominal aortic calcification in patients on regular HD and to evaluate the effect of parameters on frequency and severity of abdominal aortic calcification. Fifty-four patients with end-stage renal disease on regular HD were studied from January 2011 to December 2011 to evaluate abdominal aortic calcification by plain abdominal X-ray. The study showed that 10 (18.5%) patients had abdominal aortic calcification. Only one (1.9%) had grade 3 calcification and among the remaining, five (9.3%) patients had grade 1 and four (7.4%), grade 2. There was a statistically significant difference (P <0.05) in the means of serum cholesterol among those with and without abdominal aortic calcification. Hypertension was noticed in most patients with abdominal aortic calcification. The frequency of abdominal aortic calcification is directly related to age and duration of dialysis. The only biochemical parameter with a statistically significant effect was serum cholesterol
