In this paper, we describe a stabilization method for linear time-delay systems which extends the classical pole placement method for ordinary di7erential equations. Unlike methods based on :nite spectrum assignment, our method does not render the closed loop system, :nite dimensional but consists of controlling the rightmost eigenvalues. Because these are moved to the left half plane in a (qua...

The similarity model commonly used in laser plasma calculations is shown to be identical with the uniformly expanding universe model analysed by Heckmann 1. A solution is found to the corresponding gasdynamic equations also for the case of nonvanishing entropy production. The solution is analytic for a class of heat input rates. Heat input is shown to affect the gas motion in an exponential man...

Plasma display panels (PDP) are now a commonly used display technology for both commercial information display purposes and consumer television applications. Despite the widespread deployment of these displays, it was not commonly known whether these displays could be used successfully for time-sequential stereoscopic 3D visualization (i.e. using LCS 3D glasses). We therefore conducted a study ...

objective: recently, phage display libraries have received enormous attention for identification and isolation of pharmaceutical molecules with diagnostic and therapeutic properties. peptide libraries are known as one of the most important and widely used types of phage display libraries. in the current study, we aimed to screen the ph.d.tm-7 phage display peptide library through biopanning for...

random peptide libraries (rpl) displayed on the surface of filamentous bacteriophages have been extensively used as a tool to map epitopes or to identify antigenic mimics (mimotpoes) of disease-specific monoclonal antibodies or polyclonal sera. these rpl are engineered by the insertion of degenerate oligonucleotides, encoding a specific number of random amino acids, in frame with a bacteriophag...

In streaming acquisitions the data changes over time. ThemeRiver and line charts are common methods to display data over time. However, these methods can only show the values of the variables (or attributes) but not the relationships among them over time. We propose a framework we call StreamVis that can display these types of streaming data relations. It first slices the data stream into diffe...

background: in some disorders such as diabetes mellitus patients can display depressive symptoms. metformin is among the first-line treatments for management of the type 2 diabetes mellitus which may have some anti-depressant effect. objective: current investigation was performed to examine the anti-depressant effects of metformin and the involvement of nitric oxide (no) in this way, in an expe...

Abstract Mechanical metamaterials possess unusual mechanical properties that cannot be found in nature. Auxetic have negative Poisson's ratios and tend to expand a direction perpendicular the axial extension direction. When ratio of display circuit board is forced −1 by adopting an auxetic metamaterial, can stretchable without image distortion, this called meta‐display study. The critical obsta...

background: along with the rapid growth of technology its related tools such as computer, monitors and video display terminals (vdts) grow as well. based on the studies, the most common complaint reported is of the vdt users. methods: this study attempts to design a proper tool to assess the visual fatigue of the vdt users. first draft of the questionnaire was prepared after a thorough study on...
