A lthough many studies have shown that environmental tobacco smoke (ETS) or passive smoking increases the risk of coronary heart disease (CHD), there is still scepticism. This may be due to the small magnitude of the effect (about 25–35% increase ), inadequate adjustment for confounding variables, and misclassification of passive smoking. To estimate exposure, the majority of previous studies u...

The basis of haptic teleoperation focuses on augmenting a user’s ability to perform a task in a remote environment. Using an energetically passive haptic master assures that the energy can only be redirected or removed from the humanmanipulator pair, guaranteeing the user’s safety. However using a passive master complicates the display of haptic forces due to the device’s limitations. The maste...

The purpose of this paper is to study the realization theory of quantum linear systems. It is shown that for a general quantum linear system its controllability and observability are equivalent and they can be checked by means of a simple matrix rank condition. Based on controllability and observability a specific realization is proposed for general quantum linear systems in which an uncontroll...

One of structural passive control methods is to use Tuned Liquid Damper (TLD). However, because of the nature of the TLD, only one tuning frequency can be created when the water is sloshing. To fix this problem, some installed rotatable baffles can be embedded inside TLD called Variably Baffled TLD (VBTLD) where by changing the angle of the baffles a tuning frequency range is created. This gives ...

background: the effect of smoking cigarettes is followed by diverse effects on ovaries and developing follicles but the effect of passive smoking on ovarian function is unknown. on the other hand, the ovarian response to induction is a very important step in assisted reproduction. the aim of this study is to compare ovarian response in passive smokers and non-passive smokers in an assisted repr...

Purified coronavirus, detergent extracts of purified coronavirus, and virus-infected Madin-Darby bovine kidney cells were evaluated as antigen substrates in enzyme-linked immunosorbent assay (ELISA) and passive hemagglutination systems. Only detergent-extracted and -unextracted, purified viruses were reactive as antigen substrates in ELISA, whereas all three antigen preparations could be used f...

A current controllable current-mode universal filter with four inputs and one output employing multi-output current-controlled current conveyors (MOCCCIIs) is described. The proposed circuit offers the following attractive features: employment the minimum number of active and passive components, i.e., two MOCCCIIs and two grounded capacitors; simultaneous realization of all the standard filteri...

Large memories require too much computing resources to be fully extracted and simulated. In this paper we present an accurate power and timing modeling technique that significantly reduces characterization resources. The model is based on current controlled generators, and can be used in several regular structures. Lowpower memories are more easily characterized using this technique, since they...

Existing FPGA architectures can be classified along two dimensions: reprogrammable vs. one-time programmable and general-purpose vs. domain specific. The most challenging class of FPGA architectures to design is the reprogrammable, general-purpose FPGA, of which Xilinx is the most wellknown example. In this paper we describe Triptych, a new FPGA architecture that addresses two problems of curre...
