25. Preliminary results of an instrument for measuring the optical aberrations of the human eye
The human eye, as our biological vision instrument, contains intrinsic optical defects, referred to as optical aberrations or ametropia. The immediate consequence of such aberrations is poor quality of images formed at the retina. With the advent of more precise pulsed lasers for eye surgery, the development of instrumentation to determine precisely the high

26. Adaptive technology in computer engineering: state of art and applications. / Tecnologia adaptativa em engenharia de computação: estado da arte e aplicações.
Neste trabalho é apresentado um conjunto de contribuições teóricas e práticas que buscam solidificar alguns conceitos da teoria dos dispositivos adaptativos baseados em regras, enfatizando a sua alta aplicabilidade. Uma ferramenta de apoio ao desenvolvimento de autômatos adaptativos, incluindo recursos de animação gráfica, foi desenvolvida de acordo

27. A mathematical formulation of the boundary integral equations for a compressible stokes flow
A general boundary integral formulation for compressible Stokes flows is theoretically described within the framework of hydrodynamic potentials. The integral equation is implemented numerically to the study of drop expansion in compressible viscous flows. Marker point positions on the drop interface are involved by using the boundary integral method for cal

28. "Implementação monolitica de uma rede neural para assistencia em equalização adapatativa de sinais"
The design and test of a Kohonen neural network VLSI ASIC for adaptive signal equalization purposes is presented. The ASIC is used in the decision stage of a DFE (Decision Feedback Equalizer) and QAM (Quadrature Amplitude Modulation) with 16 symbols was considered. A comparative study of this adaptive equalizer and conventional types was done. The ASIC was f

29. Controle em destilação batelada : controle adaptativo e controle preditivo com modelo baseado em redes neurais artificiais
Separation processes are very important in chemical industries where batch distillation appears as one of its oldest processes. Over the last few years batch processing has received renewed attention because of the growing interest in the production of high-technology, high-value added chemical and biochemical products and also in environmental problems of i

30. Alkylating Agents Induce Uvm, a Reca-Independent Inducible Mutagenic Phenomenon in Escherichia Coli
Noninstructive DNA damage in Escherichia coli induces SOS functions hypothesized to be required for mutagenesis and translesion DNA synthesis at noncoding DNA lesions. We have recently demonstrated that in E. coli cells incapable of SOS induction, prior UV-irradiation nevertheless strongly enhances mutagenesis at a noninstructive lesion borne on M13 DNA. Her

31. A new decision sciences for complex systems
Models of complex systems can capture much useful information but can be difficult to apply to real-world decision-making because the type of information they contain is often inconsistent with that required for traditional decision analysis. New approaches, which use inductive reasoning over large ensembles of computational experiments, now make possible sy

32. Library services for people with disabilities: results of a survey.
The Americans with Disabilities Act (ADA), enacted in 1990, has had a significant impact on the way many institutions, including libraries, do business. The Association of Research Libraries surveyed its members in 1991 to determine the effect of this legislation, and the author conducted a similar survey in 1995 to learn what progress academic health scienc

33. The Networked Health Enterprise: A Vision for 2008
Informatics and information technology hold the promise of a consumer-centered health enterprise—one that provides quality care at a cost society is willing to pay; one where need-based, adaptive, competency-based learning results in cost-effectiveness of health education; one where team-based health and learning on demand, coupled with monitoring of

34. Memory reconsolidation for natural language processing
We propose a model of memory reconsolidation that can output new sentences with additional meaning after refining information from input sentences and integrating them with related prior experience. Our model uses available technology to first disambiguate the meanings of words and extracts information from the sentences into a structure that is an extension

35. Alphavirus-based expression vectors: strategies and applications.
Alphaviruses are positive-strand RNA viruses that can mediate efficient cytoplasmic gene expression in insect and vertebrate cells. Through recombinant DNA technology, the alphavirus RNA replication machinery has been engineered for high-level expression of heterologous RNAs and proteins. Amplification of replication-competent alpha-virus RNAs (replicons) ca

36. Elevated blood pressure and enhanced myocardial contractility in mice with severe IGF-1 deficiency.
To circumvent the embryonic lethality of a complete deficiency in insulin-like growth factor 1 (IGF-1), we generated mice homozygous for a site-specific insertional event that created a mutant IGF-1 allele (igf1m). These mice have IGF-1 levels 30% of wild type yet survive to adulthood, thereby allowing physiological analysis of the phenotype. Miniaturized ca
