The high resolution and sensitivity provided by ALMA will reveal new small scale structures in many sources, e.g. star forming regions. Such inhomogeneities may not have been considered in the analysis of past observations but they will be essential to the understanding of future data. Radiative transfer methods are needed to interpret the observations and the presence of complicated source str...

In this paper, advanced mission programming issues for autonomous vehicles are addressed. We describe the use of structural speciication and formal veriication in experiments involving the PRAXITELE project's autonomous vehicles. The environment used, called Orccad, proposes a coherent approch from hight-level speci-cation of missions down to its implementation, by harmoniously integration disc...

When it is compared to other premodern societies, ihe Greek world, in 800-300 BC, was prosperous. The Greek economy grew (both in the aggregate and per capita) at a hight rate by premodern standards (although growth was feeble by modern standards). By the fourth century BC Hellas was comparatively densely populated and highly urbanized. Incomes of working people were high (at least in Athens) a...

We have designed a new system for real-time interactive visualization of results taken directly from large-scale simulations of 3-D mantle convection and other large-scale simulations. This approach allows for intense visualization sessions for a couple of hours as opposed to storing massive amounts of data in a storage system. Our data sets consist of 3-D data for volume rendering with sets ra...

In situ elaboration of YBaCuO thin films, on polycrystalline yttria doped zirconia substrates, has been optimized. A reactive sputtering model has been developed and the electrical conductivity of the substrate has been studied as a function of temperature and doping. The Jc value of ≈ 3× 10 4 A/cm at 77 K, measured on microbridges, is among the best reported in the literature for this substrat...

The aim of this paper was to investigate the anthropometric and strength characteristics of elite male volleyball athletes and determines if differences exist in these characteristics between starters (S) and non-starters players (NS). A group of 22 professional male team volleyball players participated in the study and the players were categorized as S (n= 13) and NS (n= 9). Anthropometric cha...

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in pre-menopausal women characterized by menstrual cycle disturbances, chronic anovulation, and clinical and/or biochemical hyperandrogenism. Although, the primary etiology of PCOS remains unknown, insulin resistance/hyperinsulinemia plays a pivotal role in the pathogenesis of the syndrome. A growing body of recent data supp...

A very small change in Iterated Prisoner's Dilemma (I.P.D.) payoo matrix leads to an iterated game called Iterated Lift Dilemma 1 which properties are very diierent than classical I.P.D. The following points are to be noted: (i) two levels of cooperation are now possible, the best one needs a diicult coordination between considered strategies; (ii) only probabilis-tic strategies can make a high...

In many applications one is concerned with the approximation of functions from a finite set of scattered data sites with associated function values. We describe a scheme for constructing a hierarchy of triangulations that approximates a given data set at varying levels of resolution. Intermediate triangulations can be associated with a particular level of a hierarchy by considering their approx...

Among the environmental stress factors the most widely limiting for crop production on a global basis is water. Water stress has been found to decrease productivity of most plant particularly soybean. The aims of the study are isolation and propagation of nodule bacteria from root of mungbean by using YEMA media, characterization of nodule bacteria by using YEMA + Congored and the investigation...
