Multi-faceted cooperation is a must in protecting the marine environment as exemplified by the invasive ctenophore Mnemiopsis leidyi and marine litter cases in the western Asian seas



Multi-objective approaches to public debt management
Balıbek, Emre; Köksalan, Murat; Department of Operational Research (2008)
Public debt managers have a certain range of borrowing instruments varying in their interest rate type, currency, maturity etc. at their disposal and have to find an appropriate combination of those while raising debt on behalf of the government. In selecting the combination of instruments to be issued, i.e. the borrowing strategy to be pursued for a certain period of time, debt managers need to consider several objectives that are conflicting by their nature, and the uncertainty associated with the outcome...
Multi-hazard reliability of electric power transmission networks with spatially correlated components
Altay, Umut; Dener Akkaya, Ayşen.; Department of Statistics (2019)
Many network systems such as, gas and water pipelines, power transmission and distribution systems, highways and communication systems extend spatially over large geographical regions. Such network systems are composed of interconnected components which form paths. Correlation, resulting from similar topography, soil conditions as well as external loading due to the same environmental factors, between the behaviour of those elements should be taken into consideration and be quantified. In this respect the s...
Multi-media reservoirs depleted by horizontal wells: analysis of pressure behaviours and rate transient accompanied by developing analytical models for flow regimes
Al-Rbeawi, Salam (Inderscience Publishers, 2020-01-01)
This paper focuses on analysing pressure behaviours and rate transient of multi-porous media formations such as carbonate reservoirs depleted by horizontal wells. Several analytical models (pressure transient and rate transient) have been developed using the well-known dual-porosity models for naturally fractured formations and modified for triple-media formations considering the existence of hydraulic fractures. The solutions of these models demonstrate different flow regimes corresponding to different pro...
Multi-image region growing for integrating disparity maps
Leloglu, UĞUR MURAT; Halıcı, Uğur (1999-01-01)
In this paper, a multi-image region growing algorithm to obtain planar 3-D surfaces in the object space from multiple dense disparity maps, is presented. A surface patch is represented by a plane equation and a set of pixels in multiple images. The union of back projections of all pixels in the set onto the infinite plane, forms the surface patch. Thanks to that hybrid representation of planar surfaces, region growing (both region aggregation and region merging) is performed on all images simultaneously. Pl...
Multi-Period Reactive Power Optimization for Determination of Switch Statuses of Shunt Elements and Voltage Setpoints of Power Plants
Elma, Ismail; Güven, Ali Nezih (2021-01-01)
© 2021 Chamber of Turkish Electrical Engineers.Transmission system operators (TSOs) need to control voltages along the grid to have an economic and reliable system operation. Due to fixed and operational costs of switching equipment of shunt elements, TSOs are expected to minimize the number of switching operations of these devices. The purpose of this study is to optimize reactive power flows so as to have minimum transmission losses and number of switching operations of controllable shunt elements within ...
