Filters are the first order means by which signals are processed in electronic circuits. In advanced classes, filters can be designed to perform very sophisticated operations—the kinds of filters in your cell phones, for instance, can extract tiny signals from under huge noise backgrounds—but at this point our goal is to learn how to do things like remove unwanted noise or enhance transmission ...

objective(s): crocin influences many biological functions including memory and learning. the present study was aimed to investigate the effects of crocin on learning and memory impairments in streptozotocine-induced diabetic rats. materials and methods: diabetes was induced by intraperitoneal (ip) injection of streptozotocin (stz, 45 mg/kg). transfer latency (tl) paradigm in elevated plus-maze ...

Creating effective transfer functions for high dynamic range scalar volume data is a challenging task. For data sets with limited information about their content, deriving transfer functions using mathematical properties (gradient, curvature, etc.) is a difficult trial and error process. Traditional methods use linear binning to map data to integer space for creating the transfer functions. In ...

the seismic analysis of structures in the past relied on the assumed soil desirable effects as the elongation of excitation period with higher damping. therefore, imposing earthquake loading at the foundation level fulfilling higher safety requirements was the common practice until occasional movement amplifications demanded more rigorous research. the goal of the current study is to scrutinize...

This paper addresses the root locus locus of positive gain and the complementary root locus locus of negative gain of biproper transfer functions transfer functions with the same number of poles and zeros . It is shown that the root locus and complementary root locus of a biproper transfer function can be directly obtained from the plot of a suitable strictly proper transfer function transfer f...

Arterial transfer functions have been promoted for the derivation of central aortic waveform characteristics not usually accessible noninvasively, but possibly of prognostic significance. The utility of generalized rather than gender-specific transfer functions has not been assessed. Invasive central aortic and noninvasive radial (Millar Mikro-tip tonometer) blood pressure waveforms were record...

This paper is concerned with α– and D–negative imaginary systems. The definition of α–negative imaginary transfer functions is firstly introduced. Then, the relationship between negative imaginary and α–negative imaginary transfer functions is studied. By means of the generalized inverse, an α–negative imaginary lemma is proposed to test the α–negative imaginary property of transfer functions. ...

introduction: age-related decreases in cognitive functions such as executive functions are a common phenomenon. cognitive rehabilitation with two main approaches, compensation and remediation, is used to help elderlies coping with these deficits. despite reported benefits, there are doubts on the efficacy of each of these approaches. we tried to provide effective computerized cognitive tasks as...

Mand functions for two stimuli (A1 and A2) were trained for 3 children with autism and were then incorporated into two related conditional discriminations (A1-B1/A2 -B2 and B1-C1/B2-C2). Tests were conducted to probe for a derived transfer of mand response functions from A1 and A2 to C1 and C2, respectively. When 1 participant failed to demonstrate derived transfer of mand response functions, t...
