the effect of traffic density on the accident externality from driving the case study of tehran
در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...

My long-term research goal is to develop a methodology for robust real-time decision-making in autonomous systems. To achieve this goal, my students and I research novel decision-making algorithms and use these algorithms to build planning modules that enable complex robotic systems to operate autonomously. Our approach is currently based on pushing the limits of graph searchbased planning. Con...
متن کاملResearch Statement Maxim Likhachev
Autonomous robots rely heavily on their ability to plan actions quickly, under massive uncertainty and with a large number of factors that affect execution. Graph searches such as Dijkstra’s search, Breadth-First Search and A* [13] are highly popular means of finding least-cost plans due to their generality, solid theoretical ground and simplicity in the implementation. Unfortunately, these met...
متن کاملOn The Derivation Of A Conversational Maxim
A conversational maxim of relation -a principle of connectedness of text -is derived from a more general & independently motivated principle governing the interpretation of sentences in context. This principle -PIM, principe d'interpretation minimale -that sentences are interpreted in the most redundant way possible, is thus seen to be fundamental, & a general argument is given that the stateme...

A quasi-exactly solvable model is one for which it is possible to solve the Schrödinger equation exactly for a finite portion of the energy spectrum [1]. In quantum chemistry, a famous example of this is the Hooke’s law atom [2–5], which consists of a pair of electrons, repelling Coulombically but trapped in a harmonic external potential. This model and others [6–12] have been used extensively ...
