rice blast, caused by pyricularia grisea, is one of the most important diseases of this crop in iran and all over the world. to evaluate the relationship between spore population (sp) and meteorological factors, sp was measured daily using spore trap during growing seasons of 2006-2008 in rasht and lahijan regions (guilan province, iran). weather data including precipitation, daily maximum and ...

Measurement techniques always presuppose a theoretical model of the phenomenon under measurement. Usually the construction and the validation of the model underlining the measurement process is based on a priori knowledge. When measurement process concerns complex phenomena, model analysis cannot be only based on a priori hypothesis, but it must be performed continuously. This intelligent activ...

Evapotranspiration is one of the major parameter in the hydrologic cycle. Standard measurements of this parameter is quite complex due to various factors such as variation of precipitation amount, spatial variation by latitude and longitude and changes in environment and specific site conditions. Although of this complexity, various methods were developed to estimate actual and potential Evapot...

An information system has been designed for monitoring the quality of multiassortmental manufacturings of phosphorus – containing products substances. The information system is based on the international CALS standard (ISO-10303 STEP). It contains the following information for the main elements of analytical monitoring: a list of elements to be monitored (substance classifier), details of the a...

− Structured light systems are widely used for three-dimensional shape reconstruction. The accuracy of the vision system parameters is of paramount importance for the accuracy of the 3D reconstruction. Often the extrinsic parameters change over time due to environmental conditions, in order to compensate for structured light parameters change, a self-recalibration method based on planar homogra...

Several statements on the still debated issue of stabilometry standardization were agreed upon by the ISPGR Standardization Committee. • A set of metrological characteristics for stabilometric platforms was defined. • Relying both on practice and experimental verification it was agreed that, to obtain appropriate accuracy and sensitivity in the Romberg Test: o The acquisition interval should no...
