This work is concerned with the approximation and the numerical computation of polygonal minimal surfaces in IR q (q 2). Polygonal minimal surfaces correspond to the critical points of Shiiman's function. Since this function is analytic, polygonal minimal surfaces can be characterized by means of the second derivative of. We present a nite element approximation of quasiminimal surfaces together...

This paper presents a general method for combining stereo surfaces using a Kalman filter. A measure of error in surface representation is suggested, and the work shows how a set of surfaces may be combined to give a single surface which minimises this measure. The analysis shows how a stochastic surface may be generated using stereo, and how errors in surface-to-surface registration may be mode...

knowledge of the warming or cooling effects induced by asphalt or grass covered areas, may improve our understanding of how thermal stress or thermal comfort is created for workers who have to work outdoors for long hours in warm seasons. for this purpose a field measurements were carried out to know the cooling and warming effects of two adjacent areas, one covered with grass and the other wit...

I hereby certify that this material, which I now submit for assessment on the programme of study leading to the award of Masters of Science is entirely my own work and has not been taken from the work of others save and to the extent that such work has been cited and acknowledged within the text of my work. Date: I The first aim of this project was the characterisation of the VG Scientific Clam...

Large surface computing devices (wall-mounted or tabletop) with touch interfaces and their application to collaborative data analysis, an increasingly important and prevalent activity, is the primary topic of this book. Our goals are to outline the fundamentals of surface computing (a still maturing technology), review relevant work on collaborative data analysis, describe frameworks for unders...

PURPOSE A preliminary investigation was conducted to evaluate and compare the effectiveness of two closed-system products in preventing contamination of typical pharmacy workplace surfaces with cyclophosphamide during simulated hazardous drug preparation activities in a controlled laboratory setting. METHODS Two separate trials simulating hazardous drug compounding using cyclophosphamide were...

[1] Dusty regolith particles accumulate charge through grain-grain contact and contact with various surfaces. These processes affect vertical and horizontal transport and may cause electrical discharges in dust storms. We report the results of a simple experimental setup used to investigate the contact charging properties of two planetary analog dust samples: lunar (JSC-1) and Martian (JSC-Mars...

In the present work, functionalized 304 stainless steel metallic surfaces were created with the use of a Femtosecond Laser Surface Processing (FLSP) technique. The laser processing technique produces self-organized micro/nanostructures on the surface. The heat transfer performance of various FLSP functionalized surfaces were characterized through pool boiling and Leidenfrost experiments. Enhanc...

This paper is concerned with the construction of extremal elliptic K3 surfaces. It gives a complete treatment of those fibrations which can be derived from rational elliptic surfaces by easy manipulations of their Weierstrass equations. In particular, this approach enables us to find explicit equations for 38 semi-stable extremal elliptic K3 fibrations, 32 of which are indeed defined over Q. Th...
