(2006)This paper presents all the general overview of the interconnected power system in Turkey which consists of 30 generation and 35 load buses, totaling 65 buses connected each other with 380-kV power transmission lines. Also ... -
On the orthogonality of block wavelet transforms [Blok dalgacik dönüşümlerinin dikligi üzerine]
(2006)In this paper, orthogonality of Block Wavelet Transforms (BWT) is shown. First the orthogonality of one-stage and two-stage Block Wavelet Transforms is shown, then the result is generalized for multi-stage Block Wavelet Transform -
A time improvement over the Mycielski algorithm for predictive signal coding: Mycielski-78
(2006)The Mycielski algorithm is commonly known for applications requiring high quality predictions due to its infinite-past rule based prediction method. Since it repeatedly searches from the beginning of the data source, the ... -
A preliminary detailed study on constructed hybrid (wind-photovoltaic) system under climatically conditions of Eskisehir Region in Turkey
(2006)Wind and solar power provide a clean energy resource and are promising in the short term in Turkey. In this study, the usage of wind and solar energy to produce electricity and the possibility of electrical energy production ... -
Performance of file replication policies for real-time file access in data grids
(Association for Computing Machinery, Inc, 2007)A variety of file replication and replacement algorithms were proposed for the Data Grids in the literature. On the other hand, real-time Grid applications are emerging in many disciplines of science and engineering. Thus, ... -
Pdf sharpening for multichannel predictive coders
(2006)Predictive coders that split the prediction decision into con-texts depending on the local image behaviour have proved to be practically useful and successful in image coding applications. Such predictive coders can be ... -
Separation of noisy astrophysical images by blind time-frequency source separation methods [Gürültülü astroflziksel görüntü karişimlannin kör zaman-siklik kaynak ayriştirma yöntemleri ile ayriştirilmasi]
(2007)Two blind time-frequency source separation methods in the literature are adapted to astrophysical image mixtures and four algorithms are developed to separate them into their cosmic components; cosmic microwave background ... -
Deadlock analysis for continuous Petri nets by using overlapping decompositions
(2007)The continuous Petri nets model, in which the tokens are denoted by real numbers and the firing of transitions depends on speeds of each transition and time, is considered to analyse deadlock in this work. Deadlock analysis, ... -
Endpoint detection of isolated words using center of gravity method [Agirlik merkezi yöntemini kullanarak yalitik kelimelerin uç noktalarinin belirlenmesi]
(2007)In this study, center of gravity (COG) method is proposed to detect endpoints of isolated words. Common vector approach (CVA) is employed to evaluate the effect of the proposed method in the isolated word recognition. Since ... -
Topology based corner detection [Topolojiye dayali köşe tespiti]
(2007)A new corner detection algorithm based on the topological median filter is proposed. Topological quasi dilation and erosion operators with circular structuring element are used to detect the corners on gray level images. -
Decentralized robust flow controller design for data-communication networks
(2007)An important problem in the operation of data-communication networks is congestion. A tool which is used to avoid congestion is flow control. A flow controller decides on the rate of messages to be admitted to the network ... -
On the performance limitations of quarter-car active suspension models
(2007)In this paper, constraints on the road disturbance transfer functions are derived for a quarter-car active suspension system. The derived constraints complement the existing constraints in the literature. By using the ... -
A simulation algorithm for real systems using petri nets
(2007)The real systems are considered to determine all states in the given time interval in this work. The timed Petri net that time delays are assigned to the transition is chosen to model for the real systems. Then, a new class ... -
A novel lossless image compression approach: "Cooperative prediction"
(2007)Conditional predictive image coders (such as LOCO, CALIC, etc.) split the prediction rule into logical cases (channels) and produce prediction residuals for each case. It is a known fact that the distributions of these ... -
A reversibility enforcement approach for Petri nets using invariants
(2008)Petri net model which is one of the most common modelling method of discrete event systems, is considered to enforce reversibility in this work. Reversibility guarantees that the intial state is reachable from any state ... -
Influence of tire damping on the H2 optimally designed half-car active suspensions
(2008)In this paper, the rms responses of the heave and pitch accelerations, the suspension travels, and the tire deflections of a half-car model excited by random road inputs are studied. The road excitation at the front wheel ... -
Randomness analysis of Antimycielski number generator [Anti-mycielski sayi ureteci·ni·n rastsallik anali·zi·]
(2008)Random number generation is one of the important issues of cryptography. Based on the efficient Mycielski predictor, we propose a new random number generation algorithm, denoted by Anti-mycielski, which generates a new ... -
