In reality, traffic demands are quite random, which usually deviate from the application conditions of a certain kind of signal control method and compromise the efficiency of traffic control. To solve such a problem, taking a typical isolated intersection as the research object, the adaptive control of an isolated intersection based on a complete phase group is proposed, which can automatically optimize...
The purpose of this paper is study how to finding users with similar interests and recommending the tourist Spots to them effectively in big data, and use a framework for real-time recommendation. Due to the character of sparse data In field of tourism, the commonly method is according to user context, using a similarity algorithm clusters the users, Then suggesting the tourist spots to users with...
Contention for shared resources is a major performance issue in multicore systems. In embedded multicore microcontrollers, contentions of program flash accesses have a significant performance impact, because the flash access has a large latency compared to a core clock cycle. Therefore, the detection and analysis of program flash contentions are necessary to remedy this situation. With a lack of existing...
Positron Emission Mammography (PEM) imaging systems with the ability in detection of millimeter-sized tumors were developed in recent years. And some of them have been well used in clinical applications. In consideration of biopsy application, a double-plane PET is more practical than a ring detector for the convenience of breast immobilization. In this study, the possibility of the imaging-guided...
This paper addresses the problem of task allocation in real-time distributed systems with the goal of maximizing the system reliability, it has been shown to be NP-hard. Many studies have been made to solve this problem without considering the real-time constraint. We first take account of the deadline constraint in order to formulate this problem, and then propose an improved simulated annealing...
Due to the growth of economy, electricity demands especially the peak power demands in the United State are expected to increase significantly in the next few decades. Since the infrastructure for the new capacity of generation, transmission, and distribution to satisfy this increasing demand is highly capital intensive, demand response, concerning about shifting or curtailing the electricity demand...
Due to the mounting electricity demand from industrial sector of United States and the expected huge investment for new generation capacity, the significance of load management at the customer side has been gradually recognized by both academia and industry. Compared with many research efforts in long term production planning to shave the peak demand, seldom work on real time electricity demand response...
This paper analyses the relationships of two types of window-based real-time constraint, the sliding and fixed window constraint. First, based on the definition of "strict harder", the paper gives out the computing system of window constraints. These analyses of the constraints are useful for designing the scheduling algorithms. Thereby, a scheduling framework that is capable of adapting...
This paper analyses the computational relationships of two types of window-based real-time constraint, sliding and fixed window constraint. First, based on the definition of "strict harder", the paper gives out the computing system, making possible of precisely comparing or translating window constraints. The analyses on the constraints are helpful for arranging task scheduling. Thereby,...
