In this paper we consider linear, lumped, finite networks composed of interconnections of time-variable and passive resistances, capacitances, inductances, gyrators and transformers. We assume an impedance matrix port description of the network is given and solve the problem of synthesising the impedance, that is, we determine a set of passive elements and a scheme of interconnection which yiel...

Identification of the human genetic health hazard from exposure to chemicals of a diverse nature is of significant importance from a public health standpoint. A wide variety of organisms ranging from phage to human cells in culture may be used as tester strains to identify the mutagenic capability of a chemical. While these systems do supply genetically useful information, their major limitatio...

An experiment in which the third Stokes parameter thermal emission from a periodic water surface was measured is documented. This parameter is shown to be related to the direction of periodicity of the periodic surface and to approach brightnesses of up to 30 K at X band for the surface used in the experiment. The surface actually analyzed was a _two-layer' periodic surface; the theory of therm...

We propose a quantum trajectory analysis of a scheme to measure the states of a coupled-dot device (qubit) where there is a fluctuating energy gap Δ between the two states. The system consists of the qubit and a readout dot coupled to source and drain leads. The tunnel rate through the detector is conditioned by the occupation number of the nearer quantum dot (target) of the qubit and therefore...

In this article we present a method to determine the band spectrum, band gaps, and discrete energy levels, of a one-dimensional photonic crystal with localized impurities. For one-dimensional crystals with piecewise constant refractive indices we develop an algorithm to recover the refractive index distribution from the period map. Finally, we derive the relationship between the period map and ...

A general equation was derived, which directly describes the mathematical relationship between the allometrically predicted pharmacokinetic (PK) parameters in humans and the body weights of animal species (along with their corresponding measured PK parameters). It was shown, with use of the derived equation, that the predicted values in humans, based on combinations of animal species commonly u...

We present a coupled-mode theory of fiber-optic add-drop filters, which involve directional coupling between two fibers combined with fiber Bragg gratings defined inside the coupling region. The analysis self-consistently accounts for both the directional and the reflection coupling, and the propagation constants and structure of the supermodes of the combined structure are derived. We present ...

readymade garment industries are the prominent economic sector for bangladesh as well as scoping the huge working area for workers. but health condition of workers, drinking water quality, and proper maintenance of the environmental parameters are not well monitored. this study aims to assess the physio-chemical and bacteriological quality of drinking water provided for the garment workers in d...

Abstract—This paper proposes for the first time symbolic formula of the power spectrum of CMOS Cross Couple Oscillator and its modified circuit. Many principles existed to derived power spectrum in microwave textbook such as impedance, admittance parameters, ABCD, H parameters, etc. It can be compared by graph of power spectrum which methodology is the best from the point of view of practical m...
