Aeolian process and subsequently soil erosion are key factors in dryland environments. Such phenomena are related not only to geoecological factors (lithology, topography, and climatology) but also to land-use and plant cover changes. Formation of new sand dunes in Damghan explains the development of human activities over the past. The aim of this study is to explain the land use changes and th...

A coarse-grain parallel program typically has one thread (task) per processor, whereas a ne-grain program has one thread for each independent unit of work. Although there are several advantages to ne-grain parallelism, conventional wisdom is that coarse-grain parallelism is more eecient. This paper illustrates the advantages of ne-grain parallelism and presents an eecient implementation for sha...

A coarse-grain parallel program typically has one thread (task) per processor, whereas a fine-grain program has one thread for each independent unit of work. Although there are several advantages to fine-grain parallelism, conventional wisdom is that coarse-grain parallelism is more efficient. This paper illustrates the advantages of fine-grain parallelism and presents an efficient implementati...

Enhanced indoor radon levels are frequently found in the western part of the Swiss Jura mountains, a karst region. The activity in the limestone bedrock is low ( 20 Bq/kg). In the thin soil overburden the =Ra activity concentration is 2 to 3 times higher than in soil samples from the Swiss Plateau but on the average still below 100 Bq/kg. It is supposed that the radon problem in this region is ...

The paper gives a brief survey over a decade of R&D on coarse grain reconfigurable hardware and related compilation techniques and points out its significance to the emerging discipline of reconfigurable computing.

In this paper, we propose a method for speeding-up Digital Signal Processing applications by partitioning them between the reconfigurable hardware blocks of different granularity and mapping critical parts of applications on coarse-grain reconfigurable hardware. The reconfigurable hardware blocks are embedded in a heterogeneous reconfigurable system architecture. The fine-grain part is implemen...

In the context of the dynamical systems of classical mechanics, we introduce two new notions called “algorithmic fine-grain and coarse-grain entropy”. The fine-grain algorithmic entropy is, on the one hand, a simple variant of the randomness tests of MartinLöf (and others) and is, on the other hand, a connecting link between description (Kolmogorov) complexity, Gibbs entropy and Boltzmann entro...

Fine-grain and coarse-grain computing architectures are evaluated with regard to a hardware implementation with optoelectronic interconnects. Three examples for fine-grain optoelectronic VLSI architectures are presented and their hardware requirements are specified. Furthermore technological aspects of a realisation of an optical interface with high density for fine-grain optoelectronic VLSI ar...
