We describe the Minimal Model Program in the family of Q-Gorenstein projective horospherical varieties, by studying a family of polytopes defined from the moment polytope of a Cartier divisor of the variety we begin with. In particular, we generalize the results on MMP in toric varieties due to M. Reid, and we complete the results on MMP in spherical varieties due to M. Brion in the case of hor...

Let Γ ⊂ X be a smooth curve on a 3-fold. In this paper we classify terminal divisorial contractions E ⊂ Y −→ Γ ⊂ X contracting an irreducible surface E onto Γ, in the case when the general section of X containing Γ has D5 type singularities. In doing so we consider the problem of existence of MMP in families of canonical 3-folds, and we get results about existence of simultaneous Q-factorialisa...

this study was conducted to rank the broiler farms based on buildings, installations and equipment and its effect on production factors. to determine the contribution of each factor in ranking of farms, a multi-criteriadecision analysis (saw) was used. data of 108 broilers were recorded in specific forms and the amount of investment per broiler was calculated for individual factors. to calculat...

guilan province is the biggest hazelnut producer in iran. over 70% of hazelnut production cost is due to its manual harvesting. therefore, study on all aspects of its cultivation mechanization is necessary to sustain its production. this study focused on identifying factors that affect the development of hazelnut harvesting mechanization in guilan province, iran, using a three-round delphi tech...

The purpose of this study was analyzing the skill of Khoram Abad township wheat farmers regarding mechanization. This research was applied research and, based on methodology, was descriptive and correlative. Wheat farmers of Khoram Abad township, (N=18597) were considered as statistical population. Based on Krejcie and Morgan table, 377 ones were selected as sample. In this study, cluster rando...

There is a difference of 45% to 55% between the attainable yield and potential rice. This gap may be due insufficient inputs poor mechanization status. In this regard, agricultural utmost importance obtain satisfactory yield. study was conducted determine level, power per unit area, probit regression, challenges faced by farmers understand status in rice cultivation. For this, 98 households Pyu...

agricultural mechanization project must be identified in a short time frame to do a certain way; otherwise, cost is not the time to come and will also result in reduced yield. to avoid these costs in farming systems is necessary in any region that agricultural mechanization projects are and scheduling and planning as well as scientific until activities included in the project to fruition are do...

In a Multi-operational Machining Process (MMP), final product variation is an accumulation, or stack-up of variations generated at all the manufacturing operations. In this paper, variation transmission in the MMP is analyzed by relating part variations to operational errors from machine tools, fixtures and datums. At each operation, total part variation is separated into several components cor...

This work focuses on a robot’s task of predicting the navigation intent of human teammates using Inverse Reinforcement Learning. The purpose of this study is to introduce the On-the-fly Maximum Margin Planner (OTF-MMP) method which estimates a predictive navigation model in real-time from the observed actions of a human teammate. We include an experiment to test the predictive ability of the me...
