hysteresis has been widely recognized in the soil water relationship. in this paper, a detailed review of hysteresis was performed in relation to its models. so far, different models have been suggested to describe hysteresis in the water retention curve (wrc) that could be categorized into two main groups: conceptual and empirical models. the models in the first group are based on the domain t...

Bilginin teknoloji ile yaygınlaşması sonucu toplumlar, bilimsel araştırmalarda öncü olmak ve diğerlerinin gerisinde kalmamak için çaba harcamaktadırlar. Özellikle içinde bulunduğumuz çağın sorunlarına daha güvenilir çözümler üretmek amacıyla birçok alanda araştırmalar yapılmaktadır. Bu nedenle bilim insanları çalışmalara yönelik tutumların, olumlu geliştirilebilir düzeyde olması büyük önem taşı...

This paper presents a new approach to automatic word categorization which improves both the eeciency of the algorithm and the quality of the formed clusters. The unigram and the bigram statistics of a corpus of about two million words are used with an eecient distance function to measure the similarities of words, and a greedy algorithm to put the words into clusters. The notions of fuzzy clust...

in the present work a two dimensional numerical investigation of steam flows in a turbine blade passage is performed. a finite volume approach has been used and the pressure–velocity coupling is resolved using the simple algorithm. the purpose of this paper is to find that one of the used turbulent models is better for this kind of studies. a structured mesh arrangement with boundary layer mesh...

in this research between 3-dimensional and axisymmetric modeling for movement of nano-particles in passing through a aerodynamic lens, and also between these models and famous model of wang & liu was compared. for this purpose, output of nano-particles penetration, divergence angel, and nano-particle velocity with wang & liu model was compared. geometrical model used for aerodynamic lens compar...
