This study presents a qualitative and quantitative analysis of the output current response of a three-phase buck rectifier. The DC-side of the three-phase pulse-width modulation (PWM) buck rectifier is loaded by a typical series equivalent circuit comprising a resistor, an inductor and a constant voltage. An analytical solution of transient and steady-state processes is obtained using the diffe...

rndetermination of rock mass deformation modulus is very important in different projects, especially in civil and mining engineering works. in-situ measurements such as dilatometer, plate load and flat jack methods may be applied to determine the deformation modulus. however, these methods are very expensive and time- consuming. analytical methods are very useful approaches which can also be us...

In this paper, a proposed computational method referred to as Projected Differential Transformation Method (PDTM) resulting from the modification of the classical Differential Transformation Method (DTM) is applied, for the first time, to the Black–Scholes Equation for European Option Valuation. The results obtained converge faster to their associated exact solution form; these easily computed ...

An alpha Amyl Cinnamaldehyde Isonicotinoyl Hydrazone (ACINH) is newly synthesised novel chromogenic reagent, ACINH is used for the determination of Cd (II) by a spectrophotometric method. ACINH forms a yellow coloured water soluble [Cd (II)ACINH] complex with Cd (II) in the pH range 9.0. At λmax 380 nm the complexes shows maximum absorbance and at pH range 9.0. Hence further analytical studies ...

The Consortium on Automated Analytical Laboratory Systems (CAALS) has been formed with interested parties from the private sector and other government agencies at NIST to foster the creation of automated chemical analysis systems that will improve the quality of analytical data, facilitate the entire analytical process, and promote the standardization and transfer of analytical methods, while p...

Although the kinematics analysis of the human body has been performed through a variety of techniques, concepts and analytical methods, at present, there still is a lack of unity and consistency of these approaches. This lack of consistency, combined with the various kinematics strategies used for modelling the functional activity, leads to a lack of synthesis of the kinematics information for ...

In this paper, we study dynamical aspects of the two-dimensional (2D) gonihedric spin model using both numerical and analytical methods. This spin model has vanishing microscopic surface tension and it actually describes an ensemble of loops living on a 2D surface. The self-avoidance of loops is parametrized by a parameter kappa . The kappa=0 model can be mapped to one of the six-vertex models ...

The spatial resolution and recovered contrast of images reconstructed from diffuse fluorescence tomography data are limited by the high scattering properties of light propagation in biological tissue. As a result, the image reconstruction process can be exceedingly vulnerable to inaccurate prior knowledge of tissue optical properties and stochastic noise. In light of these limitations, the opti...

Managing the implementation of new technology in a pharmaceutical development environment has provided challenges and opportunities to obtain benefits from technologies, e.g. laboratory automation. Successful application of new techniques requires a dedicated resource. Within Pharmaceutical Technologies, this was initially a single person, who has since evolved into a team dedicated to the inve...
