homogeneity and uniformity of soil particles is a most potent factor which affects soil spectral signatures. geometric standard deviation of soil particles (?g) exhibits the homogeneity of soil components. this study presents the influence of ?g on spectral studying of soil geometric mean particle diameter as well as lime. the study was conducted in pol-e-dokhtar using the data set of lissiii-p...

preventive maintenance scheduling of generating units is addressed as a long-term scheduling in power system studies aiming to increase the reliability incorporating cost reduction. it consists of knowing which generating units should be shut down for regular safety inspection. in this paper, a new formulation of preventive maintenance scheduling associated with cost reduction index (cri) is pr...

This paper proposes arithmetic and geometric Paasche quality-adjusted price indexes that combine micro data from the base period with macro data on the averages of asset prices and characteristics at the index period. The suggested index has two types of advantages relative to traditional Paasche indexes: (i) simplification and cost reduction of data acquisition and manipulation; and (ii) poten...

In this paper we focus on compacta $K \subseteq \mathbb{R}^3$ which possess a neighbourhood basis that consists of nested solid tori $T_i$. We call these sets toroidal. \cite{hecyo1} defined the genus toroidal set as generalization classical notion from knot theory. Here introduce self-geometric index $K$, captures how each torus $T_{i+1}$ winds inside previous use in conjunction with to approa...

in order to study stress tolerance indices and identifying tolerance genotypes to drought stress condition 16 genotypes of durum wheat were assessed in a randomized complete block design with four replications under two irrigated and rainfed conditions in the research station located in west of iran ilam in 2006- 2007. results showed that variation in among durum wheat genotypes under irrigated...

drought stress is considered as the most important environmental abiotic stress, affecting grain yield of crop plants especially in arid and semi arid regions. increasing and utilization of the genetic diversity can be a useful strategy in breeding for drought resistance. in this study, twenty iranian durum wheat landraces along with two check cultivars were evaluated in a randomized complete b...

Geometric Analysis for the Cell Coverage Extension with Wireless Relay Seon-Yeong Park Department of Electrical and Electronic Eng. The Graduate School Yonsei University In this thesis, we propose the method to extend the original cell coverage covered by single source node from the viewpoint of geometric analysis. We propose the capacity theorem over our geometric model. In cell environment, w...
