© 1991 ACM.Multiversion Schedulers are now a widely accepted method for enhancing performance of the concurrency control component of a database. When the read and write sets of transactions are known in advance, the amount of concurrency provided by the Multiversion Schedulers can further be improved. In this paper, a new concurrency control technique, which uses multiversion data in conjunction with predeclared read-write sets and the Time Interval technique is suggested. With the proposed method, a transaction does not have a priori timestamp, but it obtains the most appropriate serialization number during execution. It is proved through log classification that this technique provides more concurrency than multiversion timestamp ordering.

Concurrency control in distributed databases through time intervals and short-term locks Halıcı, Uğur (Institute of Electrical and Electronics Engineers (IEEE), 1989) A method for concurrency control in distributed database management systems that increases the level of concurrent execution of transactions, called ordering by serialization numbers (OSN), is proposed. The OSN method works in the certifier model and uses time-interval techniques in conjunction with short-term locks to provide serializability and prevent deadlocks. The scheduler is distributed, and the standard transaction execution policy is assumed, that is, the read and write operations are issued contin...
Comparison of feature-based and image registration-based retrieval of image data using multidimensional data access methods Arslan, Serdar; Yazıcı, Adnan; Sacan, Ahmet; Toroslu, İsmail Hakkı; Acar, Esra (Elsevier BV, 2013-07-01) In information retrieval, efficient similarity search in multimedia collections is a critical task In this paper, we present a rigorous comparison of three different approaches to the image retrieval problem, including cluster-based indexing, distance-based indexing, and multidimensional scaling methods. The time and accuracy trade-offs for each of these methods are demonstrated on three different image data sets. Similarity of images is obtained either by a feature-based similarity measure using four MPEG-...
DDS based MIL-STD-1553B data bus interface simulation Deniz, Ertan; Oğuztüzün, Mehmet Halit S.; Durak, Umut; Department of Computer Engineering (2012) This thesis describes distributed simulation of MIL-STD-1553B Serial Data Bus interface and protocol based on the Data Distribution Service (DDS) middleware standard. The data bus connects avionics system components and transports information among them in an aircraft. It is important for system designers to be able to evaluate and verify their component interfaces at the design phase. The 1553 serial data bus requires specialized hardware and wiring to operate, thus it is expensive and complex to verify co...
Hierarchical multitasking control of discrete event systems: Computation of projections and maximal permissiveness Schmidt, Klaus Verner; Cury, José E.r. (null; 2010-12-01) This paper extends previous results on the hierarchical and decentralized control of multitasking discrete event systems (MTDES). Colored observers, a generalization of the observer property, together with local control consistency, allow to derive sufficient conditions for synthesizing modular and hierarchical control that are both strongly nonblocking (SNB) and maximally permissive. A polynomial procedure to verify if a projection fulfills the above properties is proposed and in the case they fail for a g...
Evaluation and selection of case tools: a methodology and a case study Okşar, Koray; Okşar, Koray; Department of Information Systems (2010) Today’s Computer Aided Software Engineering (CASE) technology covers nearly all activities in software development ranging from requirement analysis to deployment.Organizations are evaluating CASE tool solutions to automate or ease their processes. While reducing human errors, these tools also increase control, visibility and auditability of the processes. However, to achieve these benefits, the right tool or tools should be selected for usage in the intended processes. This is not an easy task when the vas...
