development and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولTitle : Bounded Locking for Optimistic Concurrency Control
Optimistic methods of concurrency control are gaining popularity. This is especially true with the resurgence of mobile and distributed databases, which inherently rely on optimistic techniques to improve availability and performance of the database system. A key problem with optimistic techniques is that they do not perform well in highly conflict prone environments. Pessimistic techniques, es...
متن کاملOptimistic Concurrency Control for Distributed Unsupervised Learning
Research on distributed machine learning algorithms has focused primarily on one of two extremes—algorithms that obey strict concurrency constraints or algorithms that obey few or no such constraints. We consider an intermediate alternative in which algorithms optimistically assume that conflicts are unlikely and if conflicts do arise a conflict-resolution protocol is invoked. We view this “opt...
متن کاملAn Optimistic Concurrency Control Protocol for Real-Time Database Systems
Transactions in real-time database systems are associated with certain timing constraints derived either from temporal consistency requirements of data or from requirements imposed on system reaction time. Fundamental requirements of real-time database systems are timeliness, i.e., the ability to produce expected transaction results early or at the right time, and predictability, i.e., the abil...
متن کاملRevisiting optimistic and pessimistic concurrency control
Optimistic concurrency control relies on end-of-transaction validation rather than lock acquisition prior to data accesses. Optimistic concurrency control is popular and various systems employ it based on a conviction that it increases concurrency, performance, and scalability. In contrast, we have concluded that optimistic concurrency control permits more concurrency than pessimistic concurren...
