in order to identifying factors affecting milled rice breakage losses in guilan province, a research was conducted based on the descriptive survey with association of 75 rice mill owner in guilan province. factors affecting milled rice breakage losses were recognized with the delphi technique. in this regard, a descriptive questionnaire with an open-ended question was distributed among 5 rice m...
assigning premium to the insurance contract in iran mostly has based on some old rules have been authorized by government, in such a situation predicting premium by analyzing database and it’s characteristics will be definitely such a big mistake. therefore the most beneficial information one can gathered from these data is the amount of loss happens during one contract to predicting insurance ...
A considerable portion of threshing losses and waste of rice takes place in threshing stage. One of the effective factors in threshing losses and waste of threshing units, threshers and harvesting machines, is the drum speed. In this research, effects of three factors including drum speed (five levels), crop moisture content (two levels) and rice common varieties (four varieties) on threshing l...
Field studies of S. cretica Led. damage and potential crop losses on two important cultivars of sugarcane, NCo 310 and CP 57-614, were carried out in southern Khuzestan in 1998-1999. CP 57-614 showed greater mean percentage of bored nodes and internodes (20.7%) than NCo 310 (11-2%). Apart from the direct losses in cane weight (cane yield) due to boring from the larvae, cane juice quality is als...
background the non-revenue water refers to a difference between the volume of water entering the system and billed authorized consumption. objectives the main purpose of this study is to determine the volume of non-revenue water in order to recognize the factors influencing water losses so that the information gathered can used in non-revenue water reduction management. materials and methods ka...
In this project we consider the problem of estimating the state of an unstable system in presence of correlated losses using a Kalman Filter . This scenario arises in performing vehicle tracking or navigation over a wireless channel. Since wireless channels are inherently lossy in nature, it is possible for the Kalman estimator to lose some observations. We study the behavior of Kalman filter i...
The 1990-1991 recession has intensified concerns about the consequences of workers’ job losses. To estimate the magnitude and temporal pattern of displaced workers’ earnings losses, we exploit an unusual administrative data set that includes both employees’ quarterly earnings histories and information about their firms. We find that when high-tenure workers separate from distressed firms their ...
Very long span optical communications are mainly limited by the chromatic dispersion (CD) or group velocity dispersion (GVD), fiber nonlinearities, and optical amplifier noise (Agrawal 2005). Different frequencies of a pulse travel with their own velocities, which involves a pulse spreading. In a fiber-optic communication system, information is transmitted within a fiber by using a coded sequen...
We present a generalization of the adversarial linear bandits framework, where the underlying losses are kernel functions (with an associated reproducing kernel Hilbert space) rather than linear functions. We study a version of the exponential weights algorithm and bound its regret in this setting. Under conditions on the eigen-decay of the kernel we provide a sharp characterization of the regr...
