We present a novel, simple formulation of the problem of 3D object reconstruction from images. In this formulation, the object is seen as lying at the intersection of the projection of orbits of custom built Lie groups actions. The group parameters correspond to unknown, irrelevant quantities such as the camera orientation, the depth parameters of the object with respect to the camera and the f...

ome of the tasks that cannot be solved effectively by conventional simulation have become tractable by extending the simulation to operate a in symbolic domain. Symbolic simulation involves introducing an expanded set of signal values and redefining the basic simulation functions to operate over this expanded set. This enables the simulator evaluate a range of operating conditions in a single r...

A data assimilation technique is used with a simple but widely used marine ecosystem model to optimize poorly known model parameters. A thorough analysis of the a posteriori errors to be expected for the estimated parameters was carried out. The errors have been estimated by calculating the Hessian matrices for different problem formulations based on identical twin experiments. The error analys...

Background & Aim: The major problem of pharmaceutical industry for herbal product in current scenario is authentication of raw material, and availability of standards. The quality control and quality assurance of herbal drugs still remains a challenge because of the high variability of chemical components involved. Experimental: In present research work d...

This study was aimed to investigate the effects of cream containing Ficus carica L. fruit (Fig) extract on various skin parameters such as skin melanin, erythema, moisture content, trans-epidermal water loss and sebum. For this purpose, formulation with 4% concentrated extract of F. carica fruit and base without extract were developed. Base served as a control. Both base and formulation were ap...

Polyherbal preparations are well known in certain Indian communities for malaria prophylaxis. However, quality control and quality assurance of these formulations still remain as challenges because of the high variability in combination of herbs and their phytochemical compositions. Quality control is an essential operation of the pharmaceutical process to ensure the quality herbal formulation ...

Recently Masud and Hughes proposed a stabilized mixed finite element formulation for Darcy flow. An interesting feature of this formulation is that there are no mesh-dependent parameters. In the present work we provide a derivation of this formulation based on a multiscale decomposition of the solution. We also extend the work of Masud and Hughes to three-dimensional problems and show the conve...

astigmatism’s defect has not yet been formulated in physics and medical physics books theoretically. in this paper, we are trying to formulate the astigmatism’s defect. the results of formulation show that “the degree of astigmatism is negative reverse the distance that vision’s condition of astigmatism’s chart lines change conditions in dimness angle from dimness condition at infinite distance...
