هدف از انجام این مطالعه، بررسی عوامل مؤثر بر عدم انجام به موقع عملیات ماشینی در مراحل مختلف تولید چغندرقند در استان فارس بود. با استفاده از روش نمونه گیری ساده تصادفی، تعداد 227 نفر از چغندرکاران مناطق اقلید، مرودشت و فسا به طور تصادفی انتخاب و در طول سال 1385 آمار و اطلاعات لازم با استفاده از الگوی پروبیت گرد آوری شد. نتایج این مطالعه نشان داد چنانچه تقاضا برای استفاده از امکانات و خدمات ماشین...
Colorectal cancer (CRC) is the third most common cancer and a leading cause of cancer-related mortality. Observed during CRC tumorigenesis is loss of post-transcriptional regulation of tumor-promoting genes such as COX-2, TNFα and VEGF. Overexpression of the RNA-binding protein HuR (ELAVL1) occurs during colon tumorigenesis and is abnormally present within the cytoplasm, where it post-transcrip...
Reading: Today’s material is drawn from a variety of sources. Some of the material on particle systems is drawn from lecture notes by Alex Benton from the University of Cambridge and the classic paper “Particle Systems: A Technique for Modeling a Class of Fuzzy Objects,” by W. T. Reeves, ACM Transactions on Graphics, 2, 1983, 91–108. The material on flocking is based in part on C. W. Reynolds, ...
Designing general-purpose AI systems that are capable of modeling interesting behaviors is a challenging task. On the one hand, we would like our AI system to be general enough to provide a game designer the ability to specify the subtle nuances that make a character interesting. On the other hand we would like the system to be easy to use and powerful enough that relatively simple behaviors ca...
Nasopharyngeal carcinoma (NPC), which arises from the nasopharynx epithelium, is most common in Southeast Asia, particularly in Southern China. To date, a variety of microRNAs have been demonstrated to serve key functions in the progression and development of NPC. microRNA-425 (miR-425) has previously been reported to be frequently abnormally expressed in a number of different types of human ca...
• Planning the coordinated motion of a group of agents who wish to move to a specified location amidst many obstacles • Planning the motion of an articulated skeletal model subject to constraints, such as maintaining hand contact with a door handle or avoiding collisions while passing through through a narrow passageway • Planning the motion of a character while navigating through a dense crowd...
