The OGC Web Processing Service (WPS) specification allows generating information by processing distributed geospatial data made available through Spatial Data Infrastructures (SDIs). However, current SDIs have limited analytical capacities and various problems emerge when trying to use them in data and computing-intensive domains such as environmental sciences. These problems are usually not or...

AIRIX is a linear induction accelerator which will produce by the end of 1999, a 20 MeV, 3.5 kA, 60 ns electron beam for X-Ray Radiographic applications. The high performance required for the French Radiographic Hydrotest Facility is connected to the beam quality and thus to the accelerator alignment.To minimize corkscrew motion and emittance increase of the beam, mechanical and magnetic alignm...

The paper presents a versatile library of analytic and quasi-analytic complex-valued wavelet packets (WPs) which originate from discrete splines arbitrary orders. real parts the WPs are regular spline-based orthonormal designed in [4]. imaginary so-called complementary WPs, which, unlike symmetric they antisymmetric. Tensor products 1D provide diversity 2D oriented multiple directions. computat...

This paper asks under what conditions it is possible for a wildlife department in west Africa without an external budget to protect all rare and endangered species, and if so, what is the impact on rural inhabitants engaged in hunting. Protecting wildlife in this region is particularly tricky. Hunting is important for rural livelihoods, but when unregulated can result in the loss of species. Go...

Opportunistic land encroachment, resulting from costly and incomplete enforcement of common land boundaries, is a problem in many less-developed countries. A multi-period model of such encroachment is presented in this paper. The model accounts explicitly for the cumulative effects of non-compliance of regulations designed to protect a finite, non-renewable resource – in this case common land –...

We present a systematic investigation of the magnetoresponses Weyl points (WPs) with topological charge n = 2, 3 and 4, both linear quadratic energy tilt. The tilt always tends to squeeze Landau levels (LLs) conduction valence bands all WPs, eventually leads LL collapse in type-II phase. However, has more complex influences on LLs unconventional WPs. For charge-n (n 4) WP, influence are opposit...

The latest issues in simulating and analyzing different Earth Science phenomena require the development of complex algorithms, based on satellite images in different formats. The main goal of this paper is to process these data in a standard manner and to automatically publish the execution results by using the latest Web Processing Services (WPS). The development of these services needs to be ...

Water-extracted mycelial polysaccharide (WPS) from the endophytic fungus Fusarium oxysporum Dzf17 isolated from Dioscorea zingiberensis was found to be an efficient elicitor to enhance diosgenin accumulation in D. zingigerensis cultures, and also demonstrated antioxidant activity. In this study, response surface methodology (RSM) was employed to optimize the extraction process of WPS from F. ox...

Three polysaccharides, namely exopolysaccharide (EPS), water-extracted mycelial polysaccharide (WPS) and sodium hydroxide-extracted mycelial polysaccharide (SPS), were prepared from the endophytic fungus Fusarium oxysporium Dzf17 isolated from the rhizomes of Dioscorea zingiberensis. The effects of the time of addition and polysaccharide concentration on the growth and diosgenin accumulation in...

OBJECTIVE To assess the acute effects of smoking in Waterpipe (WP) smokers in Ajman, United Arab Emirates (UAE). CONTEXT 202 male volunteers aged > 17 years were included. Blood pressure, heart rate and respiratory rate values of each participant, before and after a 30 minute smoking session, were measured and compared. Standardized questionnaires were also answered. RESULTS Mean increases ...
