wheat is the dominant cereal crop constituting the first staple food in iran. this paper studies the energy consumption patterns and the relationship between energy inputs and yield for wheat production in iranian agriculture during the period 1986 – 2008. the results indicated that total energy inputs in irrigated and dryland wheat production increased from 29.01 and 9.81 gj ha-1 in 1986 to 44...

this paper tries to systematically survey, with taking theoretical view on geomorphic basin and its changes into account. the purpose of this research is to determine the balance and stability of geomorphic basins from the past to present and then to future. consequently, it tries to determine the balance between energy and input-output materials for example (rainfall , solar radiation, tectoni...

this paper employs a multivariate dynamic conditional correlation garch model, which is developed by engle (2001, 2002), to detect the timing and nature of changes in the comovement between iranian output and prices for the periods after iran–iraq war , known as imposed war . the results showed that there is a weak correlation between output and prices after imposed war and  varies periodically...

The paper presents the development of prototype system for measurement of vital functions using the transthoracic bioimpedance. The measurement of the bioimpedance is a non-invasive method providing the information about the body composition, hearth rate, blood flow, breathing etc. The design and realization of a simple four electrode system have been done. The device is designed as a combinati...

An overview is provided of the Stravinsqi-Jun2014 algorithm and its performance on the MediaEval 2014 C@merata Task. Stravinsqi stands for STaff Representation Analysed VIa Natural language String Query Input. The algorithm parses a symbolic representation of a piece of music as well as a query string consisting of a natural language expression, and identifies where event(s) specified by the qu...
