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...

introduction: the goal of integration of digital libraries (dl) is to utilize various autonomous dls in concert to provide knowledge from such island-dls. integrated digital libraries (idls) appeared after the emergence of dls in 1990s, invention of integrated information systems from 2000 and consolidation of them during the recent decade. the ministry of health and medical education (mhme) of...

this paper describes a simple, physically-based conceptual model utilizing watershed drainage characteristics for rainfall-runoff simulation. this conceptual physiographic model is essentially based on the work of najafi (2003), which has led to a model compris-ing the main tributary subwatersheds and a single main channel subwatershed. the ki-nematic wave (kw) theory is used to describe flow o...

gilles fauconnier and mark turner have considered the issue of conceptual metaphor as a special case of more general and comprehensive matter. this vast matter is the analysis of mind system mechanism when it exposes to conceptual domains. to describe such a process, fauconnier and turner use the term of mental or conceptual space. they believe that in order to understand much of human thought ...

the study aimed at presenting an appropriate framework for designing & implementing knowledge management projects within research & knowledge-based organizations while focusing on the knowledge culture. first, the available literature was reviewed & the influential indices & factors regarding the knowledge culture were extracted. then, a conceptual model for evaluating the knowledge culture was...

zinc is the first modelling language which supports solver and technique independence. this means that a high level conceptual model can be automatically mapped into an appropriate low level design model for a specific solver or technique. to date, zinc uses three different techniques to solve a model: constraint programming (cp), local search (ls), and mixed integer programming (mip). in this ...
