Search and Rescue (SAR) operations aim at finding missing objects with minimum time in a determined area. There are fundamentally two problems in these operations. The first problem is assessing highly reliable probability distribution maps, and the second is determining the search pattern that sweeps the area from the air as fast as possible. In this study, geographic information systems (GIS) and multi criteria decision analysis (MCDA) are integrated and a new model is developed based upon Search Theory in order to find the position of the missing object as quickly as possible with optimum resource allocation. Developed model is coded as a search planning tool for the use of search and rescue planners. Inputs of the model are last known position of the missing object and related clues about its probable position. In the developed model, firstly related layers are arranged according to their priorities based on subjective expert opinion. Then a multi criteria decision method is selected and each data layer is multiplied by a weight corresponding to search expert’s rank. Then a probability map is established according to the result of MCDA methods. In the second phase, the most suitable search patterns used in literature are applied based on established probability map. The developed model is a new approach to shortening the time in SAR operations and finding the suitable search pattern for the data of different crashes.

Estimation of earthquake insurance premium rates based stochastic methods Deniz, Aykut; Yücemen, Mehmet Semih; Department of Civil Engineering (2006) In this thesis, stochastic methods are utilized to improve a familiar comprehensive probabilistic model to obtain realistic estimates of the earthquake insurance premium rates in different seismic zones of Turkey. The model integrates the information on future earthquake threat with the information on expected earthquake damage to buildings. The quantification of the future earthquake threat is achieved by making use of the seismic hazard analysis techniques. Due to the uncertainties involved, the hazard th...
Underwater target detection with hyperspectral imagery for search and rescue missions Eken, Isa Cem; Çetin, Yasemin (2018-04-19) Fast and precise target detection is an issue in underwater object detection applications such as search and rescue missions. Hyperspectral imaging could be effective in determining different elements in a region thanks to its ability to provide detailed spectral information. Utilization of this rich spectral information calls for the analysis of spectral differences of objects on water surface (dry/wet) and underwater conditions. In our study, we investigated the effect of water column to the target spectr...
UAV routing for reconnaissance mission: A multi-objective orienteering problem with time-dependent prizes and multiple connections Dasdemir, Erdi; Batta, Rajan; Köksalan, Mustafa Murat; TEZCANER ÖZTÜRK, DİCLEHAN (2022-09-01) © 2022 Elsevier LtdWe address the route planning problem of an unmanned air vehicle (UAV) tasked with collecting information from a radar-monitored environment for a reconnaissance mission. The UAV takes off from a home base, visits a set of targets, and finishes its movement at a final base. Collectable information at a target depends on the time the target is visited by the UAV. There are multiple trajectory alternatives between the target pairs with different travel time and threat attributes. A route pl...
Attenuation relationship for peak groundvelocity based on strong ground motion data recorded in Turkey Altıntaş, Süleyman Serkan; Gülkan, Polat; Department of Civil Engineering (2006) Estimation of the ground motion parameters is extremely important for engineers to make the structures safer and more economical, so it is one of the main issues of Earthquake Engineering. Peak values of the ground motions obtained either from existing records or with the help of attenuation relationships, have been used as a useful parameter to estimate the effect of an earthquake on a specific location. Peak Ground Velocities (PGV) of a ground motion is used extensively in the recent years as a measure of...
Hybrid Approach for Disaster Recovery using P2P Communications in Android Yatbaz, Hakan Yekta; Cinar, Berkem; Gokdemir, Ali; Ever, Enver; Al-Turjman, Fadi; Nguyen, Huan X.; Yazıcı, Adnan (2018-10-04) Disaster recovery and rescuing are challenging tasks due to the unknown parameters related with the victims in disastrous situations. Existing surveillance systems have a degree of efficiency to inform the people through the use of various communication channels about disasters and their area of effect. However, the obscureness of the rescuing process has not been resolved in desirable levels, especially for the cases where the communication infrastructure can also be heavily damaged. Thanks to the prevalen...
