A byproduct of experiments designed to map the CMB is the recent detection of a new component of foreground galactic emission. The anomalous foreground at 10-30 GHz, unexplained by traditional emission mechanisms, correlates with 100 mum dust emission, and is thus presumably due to dust. Is the anomalous foreground ubiquitous in the Galaxy? I will present evidence obtained with the CBI and SIMB...

The non-uniqueness of geodesics joining two given points in universal Teichm uller space is proved in the previous paper 7]. The purpose of the present paper is to discuss the non-uniqueness of geodesics in any innnite-dimensional Teichm uller space. It is proved that if 1 and 2 are two extremal Beltrami diierentials belonging to a point ] of a Teichm uller space and 1 ? 2 does not belong to N-...

In this paper, we apply the fuzzy linear regression (FLR) with fuzzy intervals analysis into a neural network classi®cation model. The FLR works as a data handler and separates the data sample into two groups. By training two independent neural works with these two groups, we can better describe the distribution space of the corresponding data sample with two different functions, rather than us...

The purpose for taking up this investigation owing to the fact that now a days natural sand confirming to Indian Standards is becoming scarcer and costlier due to its non availability in time because of Law of Land, illegal dredging by sand mafia, accessibility to the river source during rainy season, non confirming with IS 383-1970. Hence the present investigation was taken up with a view to v...

A three-dimensional hybrid cellular automata (CA) model is developed to study the dynamic process of multicellular tumour spheroid (MTS) growth by introducing hypoxia as an important microenvironment factor which influences cell migration and cell phenotype expression. The model enables us to examine the effects of different hypoxic environments on the growth history of the MTS and to study the...

As electronic channels to the customer (intelligent shelves, E-Commerce) are ideally suited to better comprehend customers' price sensitivity, communicate pricing policies and adjust prices regularly marketers are eager to charge people differently for the same product and according to their willingness to pay. This practice implies that not all customers are treated equally. Fairness concerns ...

In recent years several computational systems and techniques for theorem proving by analogy have been developed. The obvious practical question, however, as to whether and when to use analogy has been neglected badly in these developments. This paper addresses this question , identiies situations where analogy is useful, and discusses the merits of theorem proving by analogy in these situations...

We consider the scattering and lens rigidity of compact surfaces with boundary that have a trapped geodesic. In particular we show that the flat cylinder and the flat Möbius strip are determined by their lens data. We also see by example that the flat Möbius strip is not determined by it’s scattering data. We then consider the case of negatively curved cylinders with convex boundary and show th...
