45 GHz bandwidth-efficiency resonant cavity enhanced ITO-Schottky photodiodes
(OSA, 2001)We demonstrated high-performance resonant cavity enhanced ITO-Schottky photodiodes. We achieved a peak efficiency of 75% around 820 nm with a 3-dB bandwidth of 60 GHz resulting in a bandwidth-efficiency product of 45 GHz. -
Automatic performance evaluation of Web search engines
(Elsevier, 2004)Measuring the information retrieval effectiveness of World Wide Web search engines is costly because of human relevance judgments involved. However, both for business enterprises and people it is important to know the most ... -

Cache-based query processing for search engines
(Association for Computing Machinery, 2012-11-01)In practice, a search engine may fail to serve a query due to various reasons such as hardware/network failures, excessive query load, lack of matching documents, or service contract limitations (e.g., the query rate limits ... -
Circuit partitioning using mean field annealing
(Elsevier, 1995)Mean field annealing (MFA) algorithm, proposed for solving combinatorial optimization problems, combines the characteristics of neural networks and simulated annealing. Previous works on MFA resulted with successful mapping ... -
Compact optical temporal processors
(Optical Society of America, 1995)Optical signal processing can be done with time-lens devices. A temporal processor based on chirp-z transformers is suggested. This configuration is more compact than a conventional 4-f temporal processor. On the basis of ... -
A comparative study of computational procedures for the resource constrained project scheduling problem
(Elsevier, 1994)Performance of two new integer programming based heuristics together with some special purpose algorithms for project scheduling are tested from a computational point of view. The objective of the study is to compare the ... -
Comparison of local and global computation and its implications for the role of optical interconnections in future nanoelectronic systems
(Elsevier, 1993)Various methods of simulating diffusion phenomena with parallel hardware are discussed. In particular methods are compared requiring local and global communication among the processors in terms of total computation time. ... -
Compiler directed network-on-chip reliability enhancement for chip multiprocessors
(Association for Computing Machinery, 2010-04)Chip multiprocessors (CMPs) are expected to be the building blocks for future computer systems. While architecting these emerging CMPs is a challenging problem on its own, programming them is even more challenging. As the ... -
Corporate social responsibility: why bother?
(Elsevier, 2014)Corporate Social Responsibility (CSR) is not a new concept, but unfortunately has been defined in so many ways, it is often misinterpreted. In fact it has had 40 years to evolve from a somewhat infant concept to a successful ... -
Data replication versus timing constraints in distributed database systems
(ACM, 1994-03)In a database system supporting a real-time application, each transaction is associated with a timing constraint, typically in the form of a deadline. Replicated database systems possess desirable features for real-time ... -
Deriving feasible deployment alternatives for parallel and distributed simulation systems
(Association for Computing Machinery, 2013-07)Parallel and distributed simulations (PADS) realize the distributed execution of a simulation system over multiple physical resources. To realize the execution of PADS, different simulation infrastructures such as HLA, DIS ... -
Document replication strategies for geographically distributed web search engines
(Elsevier Ltd., 2013)Large-scale web search engines are composed of multiple data centers that are geographically distant to each other. Typically, a user query is processed in a data center that is geographically close to the origin of the ... -
Effect of load, processing time and due date variation on the effectiveness of scheduling rules
(Taylor & Francis, 2002)In real manufacturing environments, variations in production factors (i.e. pro- cessing time, demand, due-dates) are inevitable facts. All these dynamic changes, together with random disturbances (e.g. machine breakdowns) ... -
Effect of shell thickness on small-molecule solar cells enhanced by dual plasmonic gold-silica nanorods
(AIP Publishing, 2014-09-19)Chemically synthesized gold (Au)-silica nanorods with shell thickness of 0 nm-10 nm were incorporated into the bulk heterojunction of a small-molecule organic solar cell. At optimal (1 wt. %) concentration, Au-silica ... -
Efficiency and effectiveness of query processing in cluster-based retrieval
(Elsevier, 2004)Our research shows that for large databases, without considerable additional storage overhead, cluster-based retrieval (CBR) can compete with the time efficiency and effectiveness of the inverted index-based full search ... -
Efficient fast hartley transform algorithms for hypercube-connected multicomputers
(IEEE, 1995)Although fast Hartley transform (FHT) provides efficient spectral analysis of real discrete signals, the literature that addresses the parallelization of FHT is extremely rare. FHT is a real transformation and does not ... -
Equity ownership structure and its consequences : an empirical investigation in Turkish firms
(Bilkent University, 2001)The study describes the main characteristics of ownership structure of the Turkish nonfinancial firms listed on the Istanbul Stock Exchange (ISE) and examines the impact of ownership structure on performance and risk-taking ... -
Equity ownership structure, risk taking, and performance: an empirical investigation in Turkish listed companies
(Routledge, 2002)The paper describes the main characteristics of ownership structure of Turkish nonfinancial firms listed on the Istanbul Stock Exchange (ISE) and examines the impact of ownership structure on performance and risk-taking ... -
Evaluation of army corps artillery ammunition supply systems via simulation
(IEEE, 2002)The purpose of this paper is to discuss the evaluation of different alternatives for the implementation of Turkish army corps artillery ammunition supply system. The objective is to see whether the alternative systems ...
