An analysis of vehicular traffic flow using langevin equation
Koşun, Çağlar; Çelik, Hüseyin Murat; Özdemir, Serhan (Faculty of Transport and Traffic Sciences, University of Zagreb, 2015-01)Traffic flow data are stochastic in nature, and an abundance of literature exists thereof. One way to express stochastic data is the Langevin equation. Langevin equation consists of two parts. The first part is known as ... -
Characterization of swarm behavior through pair-wise interactions by tsallis entropy
Can, F. Cemal; Bayram, Çağdaş; Toksoy, Ahmet Kaan; Avşar, Hakan; Özdemir, Serhan (CSREA Press, 2005)This paper tries to look at the interactions of a swarm of two at an elementary level. The change in the swarm entropy during the interactions is investigated. The characterization of swarm behavior has been subsumed in ... -
Classification of manipulators of the same origin by virtue of compactness and complexity
Gezgin, Erkin; Özdemir, Serhan (Elsevier, 2011-10)This work deals with a classification method that employs concepts such as complexity and compactness. The idea is to classify manipulators, or any other mechanism for that matter, of the same origin, based on the geometry ... -
Contrast enhancement by lateral inhibition in a sensory network
Coşkun, Anıl (Izmir Institute of Technology, 2006)The most important mechanism to occur in biological distributed sensory networks (DSNs) is called "Lateral Inhibition, (L.I.)". L.I. relies on one simple principle. Each sensor strives to suppress its neighbors in proportion ... -
The control of a manipulator using cerebellar model articulation controllers
Darka, Murat (Izmir Institute of Technology, 2003)The emergence of the theory of artificial neural networks has made it possible to develop neural learning schemes that can be used to obtain alternative solutions to complex problems such as inverse kinematic control for ... -
Control of dynamics system behaviour by magnetorheological and varible orifice dampers
Kınay, Gökçe (Izmir Institute of Technology, 2013)Passive and semi-active control devices are widely utilized for response reduction in civil engineering structures subjected to strong earthquakes. These devices absorb energy from the system. They do not add energy into ... -
Cost effective localization in distributed sensory networks
Coşkun, Anıl; Sevil, Hakkı Erhan; Özdemir, Serhan (Elsevier, 2011-03)The most important mechanism to occur in biological distributed sensory networks (DSNs) is called lateral inhibition, (LI). LI relies on one simple principle. Each sensor strives to suppress its neighbors in proportion to ... -
Data driven modeling using reinforcement learning in autonomous agents
Karakurt, Murat (Izmir Institute of Technology, 2003)This research has aspired to build a system which is capable of solving problems by means of its past experience, especially an autonomous agent that can learn from trial and error sequences. To achieve this, connectionist ... -
Determining the complexity of multi-component conformal systems: A platoon-based approach
Koşun, Çağlar; Özdemir, Serhan (Elsevier, 2017-04)Many systems in nature and engineering are composed of subsystems. These subsystems may be formed in a linear, planar or spatial array. A typical example of these formations is a chain of vehicles known as platoon formation ... -
A distributed behavioral model for landmine detection robots
Bayram, Çağdaş; Sevil, Hakkı Erhan; Özdemir, Serhan (International Association of Engineers, 2007)This paper presents a distributed navigation, detection and swarming model for a group of minimalist identical robotic agents. Decision making process of agents is weight based in contrast to widely used precedence based ... -
The effects of bias, population migration and credit assignment in optimizing trait-based heterogeneous populations
Gezgin, Erkin; Sevil, Hakkı Erhan; Özdemir, Serhan (CSREA Press, 2005)Population based search algorithms are becoming the mainstay in nonlinear problems with discontinuous search domains. The generic name of genetic algorithms (GAs) basicly applies to all population based methods. GAs have ... -
An entropy-based analysis of lane changing behavior: An interactive approach
Koşun, Çağlar; Özdemir, Serhan (Taylor & Francis, 2017-05)Objectives: As a novelty, this article proposes the nonadditive entropy framework for the description of driver behaviors during lane changing. The authors also state that this entropy framework governs the lane changing ... -
Fuzzy logic algorithm for runoff-induced sediment transport from bare soil surfaces
Tayfur, Gökmen; Özdemir, Serhan; Singh, Vijay P. (Elsevier, 2003-12)Utilizing the rainfall intensity, and slope data, a fuzzy logic algorithm was developed to estimate sediment loads from bare soil surfaces. Considering slope and rainfall as input variables, the variables were fuzzified ... -

Özkan, Özün Beyhan; Tosun, Öykü Ece; Arslan, Arda; Gençer, İsmail Cenk; Özçetin, Mustafa; Serindağ, Yelda; Memiş, Korhan; Özdemir, Serhan (CSREA Press, 2012)This work investigates the effects of surface topography of the distributed sensor networks on perception through the differences in sensor readings. Compound eyes are found in some insects and crustaceans. Lateral inhibition ... -
Intelligence modeling of the transient asperity temperatures in meshing spur gears
Atan, Ebubekir; Özdemir, Serhan (Elsevier, 2005-01)Temperature rise in the contact zone of meshing gears is a serious problem in gear design. The temperature rise on lubricated surfaces may result in the significant decrease on the material strength and lubricant viscosity ... -
An investigation with fractial geometry analysis of time series
Kaya, Aysun (Izmir Institute of Technology, 2005)In this thesis, three kinds of fractal dimensions, correlation dimension, Hausdorff dimension and box-counting dimension were used to examine time series. To demonstrate the universality of the method, ECG (Electrocardiogram) ... -
