this paper develops an automatic parking algorithm based on a fuzzy logic controller with the vehicle pose for the input and the steering angle for the output. in this way some feasible reference trajectory path have been introduced according to geometric and kinematic constraints and nonholonomic constraints to simulate motion path of car. also a novel method is used for parking space detectio...

Abstractive summarization has been a longstanding and long-term goal in automatic summarization, because systems that can generate abstracts demonstrate a deeper understanding of language and the meaning of documents than systems that merely extract sentences from those documents. Genest (2009) showed that summaries from the top automatic summarizers are judged as comparable to manual extractiv...

Information transmission is an important part of the wellbore trajectory automatic control system. Combined with the characteristics of the guided drilling system, drilling fluid pulse is selected as a tool for trajectory control. Negative pulse transmission of drilling fluid is one of the key technologies to realize wellbore trajectory automatic control. In this paper, the working principle of...

In this paper, we describe our guided summarization system that participated in the TAC 2011 competition. We submitted two runs for the guided summarization task by following a random walk paradigm. Two different approaches were applied for the update component to create two runs of our guided summarization system: 1) using ROUGE (RecallOriented Understudy for Gisting Evaluation), and 2) using ...

For a number of years vehicle fleet tracking systems are in use in companies operating large number of vehicles in the field. Proliferation of cheap and compact GPS receivers had the effect that Automatic Vehicle Location (AVL) systems today almost exclusively use satellite based locating systems. This paper presents characteristics of realized city bus transit traffic in the city of Niš. Since...

Emergencies such as machine breakdowns and rush orders greatly affect the production activities of manufacturing enterprises. How to deal with rescheduling problem after emergencies have high practical value. Meanwhile, under background intelligent manufacturing, automatic guided vehicles are gradually emerging in To disturbances flexible job shop scheduling vehicle transportation, a mixed-inte...

In this paper, a new algorithm for solving the single loop routing problem is presented. The purpose of the single loop routing problem(SLRP) is to find the shortest loop for an automated guided vehicle covering at least one edge of each department of a block layout. First it shown that this problem can be represented as a graph model. Then a meta-heuristic algorithm based on and colony system ...

Synopsis This paper examines the use of knowledge-based techniques to generate a framework for the active rescheduling of an automated guided vehicle system in a manufacturing environment. Our approach to active resecheduling uses “cues” drawn from events on the shop floor to trigger rescheduling. Simulation experiments are used to capture knowledge about the shop floor and various scheduling s...

A numerical dynamic-aerodynamic interface for simulating the separation dy­n­a­m­ic­s of co­n­­s­t­r­a­i­ned strap-on boosters jettisoned in the atmosphere is presented. A 6-DOF multi body dynamic solver ،using Constraint For­ce Equation Methodology is coupled with a numerical time dependent Euler flow solver. An automatic dyna­m­i­­c mesh updating proc­e­d­ure is employed using smoothing and l...
