A multidatabase system based on OMG's distributed object management architecture and named Middle East Technical University (METU) INteroperable Database management system (MIND) is presented. MIND employs a dynamic query optimizer. After a query is decomposed, the global subsequeries are sent to the involved Local Database Agent (LDA) objects. The optimization process starts after the first partial result from a LDA object becomes available. For optimizing the intersite operations among these partial resul...
METU MMDS An Intelligent Multimedia Database System for Multimodal Content Extraction and Querying
Yazıcı, Adnan; Yılmaz, Turgay; Gulen, Elvan; Koyuncu, Murat; Sert, Mustafa (2016-01-04)
Managing a large volume of multimedia data, which contain various modalities (visual, audio, and text), reveals the need for a specialized multimedia database system (MMDS) to efficiently model, process, store and retrieve video shots based on their semantic content. This demo introduces METU-MMDS, an intelligent MMDS which employs both machine learning and database techniques. The system extracts semantic content automatically by using visual, audio and textual data, stores the extracted content in an appr...
METU Dataset: A Big Dataset for Benchmarking Trademark Retrieval
Tursun, Osman; Kalkan, Sinan (2015-05-22)
Trademark retrieval (TR) is the problem of retrieving similar trademarks (logos) for a query, and the main aim is to detect copyright infringements in trademarks. Since there are millions of companies worldwide, automatically retrieving similar trademarks has become an important problem, and currently, checking trademark infringements is mostly performed manually by humans. However, although there have been many attempts for automated TR, as also acknowledged in the community, the problem is largely unsolve...

Middle East Technical University – Defocusing Beam Line (METU-DBL) project is an irradiation facility providing 15 MeV to 30 MeV kinetic energy protons for testing various high radiation level applications, ranging from Hi-Lumi LHC upgrade, space electronic components to nuclear material research. The project located inside the premises of the TAEA (Turkish Atomic Energy Agency) SANAEM (Saraykoy Nuclear Education and Research Center) close to Ankara, provides users a wide selectable flux menu (105–1010 p/cm...
METU-Defocusing beam line project and beam optics studies
Demirköz, Melahat Bilge (2017-07-31)
METU-Defocusing Beam Line (METU-DBL) project aims to perform Single Event Effect (SEE) tests for space, nuclear and medical applications. Turkish Atomic Energy Authority (TAEA) has a 30MeV proton cyclotron at Proton Accelerator Facility (PAF) mainly for radioisotope production and an R&D room for other applications. The proton beam current is variable between 0.1µA to 1.2mA and the beam size is small. METU-DBL, which is being installed in the R&D room, will enlarge the beam size with three quadrupole magnet...
