Pap smear test görüntülerinde hücre çekirdeklerinin bölütlenmesi
(IEEE, 200904)Cervical cancer is a preventable disease and the dysplasia it causes can be scanned by using a pap smear test. It can be beneficial to develop a computerassisted diagnosis system to make the pap smear test robust and ... 
Paper and pen: A 3D sketching system
(Springer, 201310)This paper proposes a method that resembles a natural pen and paper interface to create curve based 3D sketches. The system is particularly useful for representing initial 3D design ideas without much effort. Users interact ... 
A parallel framework for inmemory construction of termpartitioned inverted indexes
(Oxford University Press, 2012)With the advances in cloud computing and huge RAMs provided by 64bit architectures, it is possible to tackle large problems using memorybased solutions. Construction of termbased, partitioned, parallel inverted indexes ... 
Parallel frequent item set mining with selective item replication
(Institute of Electrical and Electronics Engineers, 2011)We introduce a transaction database distribution scheme that divides the frequent item set mining task in a topdown fashion. Our method operates on a graph where vertices correspond to frequent items and edges correspond ... 
Parallel image restoration using surrogate constraint methods
(Academic Press, 2007)When formulated as a system of linear inequalities, the image restoration problem yields huge, unstructured, sparse matrices even for images of small size. To solve the image restoration problem, we use the surrogate ... 
Parallel minimum norm solution of sparse block diagonal column overlapped underdetermined systems
(Association for Computing Machinery, 2017)Underdetermined systems of equations in which the minimum norm solution needs to be computed arise in many applications, such as geophysics, signal processing, and biomedical engineering. In this article, we introduce a ... 
A parallel progressive radiosity algorithm based on patch data circulation
(Pergamon Press, 1996)Abstract  Current research on radiosity has concentrated on increasing the accuracy and the speed of the solution. Although algorithmic and meshing techniques decrease the execution time, still excessive computational ... 
Parallel pruning for kmeans clustering on shared memory architectures
(Springer Verlag, 2001)We have developed and evaluated two parallelization schemes for a treebased kmeans clustering method on shared memory machines. One scheme is to partition the pattern space across processors. We have determined that ... 
A parallel scaled conjugategradient algorithm for the solution phase of gathering radiosity on hypercubes
(Springer, 1997)Gathering radiosity is a popular method for investigating lighting effects in a closed environment. In lighting simulations, with fixed locations of objects and light sources, the intensity and color and/or reflectivity ... 
Parallelization of Sparse Matrix Kernels for big data applications
(Springer, 2016)Analysis of big data on largescale distributed systems often necessitates efficient parallel graph algorithms that are used to explore the relationships between individual components. Graph algorithms use the basic adjacency ... 
Parsing Turkish using the lexical functional grammar formalism
(Springer/Kluwer Academic Publishers, 1995)This paper describes our work on parsing Turkish using the lexicalfunctional grammar formalism [11]. This work represents the first effort for widecoverage syntactic parsing of Turkish. Our implementation is based on ... 
Partial evaluation of queries for bitsliced signature files
(Elsevier, 1996)Our research extends the bitsliced signature organization by introducing a partial evaluation approach for queries. The partial evaluation approach minimizes the response time by using a subset of the onbits of the query ... 
Particlebased simulation and visualization of fluid flows through porous media
(SpringerVerlag, 2010)We propose a method of fluid simulation where boundary conditions are designed in such a way that fluid flow through porous media, pipes, and chokes can be realistically simulated. Such flows are known to be low Reynolds ... 
Particlebased simulation of the interaction between fluid and knitwear
(2014)We present a particlebased method to simulate and visualize the interaction of knitwear with fluids. The knitwear is modeled using springmass systems and the fluid is modeled using the smoothed particle hydrodynamics ... 
Partitioning functions for steteful data parallelism in stream processing
(Association for Computing Machinery, 2014)In this paper we study partitioning functions for stream processing systems that employ stateful data parallelism to improve application throughput. In particular, we develop partitioning functions that are effective ... 
Partitioning hypergraphs in scientific computing applications through vertex separators on graphs
(Society for Industrial and Applied Mathematics, 2012)The modeling flexibility provided by hypergraphs has drawn a lot of interest from the combinatorial scientific community, leading to novel models and algorithms, their applications, and development of associated tools. ... 
Partitioning models for scaling parallel sparse matrixmatrix multiplication
(Association for Computing Machinery, 201804)We investigate outerproductparallel, innerproductparallel, and rowbyrowproductparallel formulations of sparse matrixmatrix multiplication (SpGEMM) on distributed memory architectures. For each of these three ... 
Partitioning sparse matrices for parallel preconditioned iterative methods
(Society for Industrial and Applied Mathematics, 2007)This paper addresses the parallelization of the preconditioned iterative methods that use explicit preconditioners such as approximate inverses. Parallelizing a full step of these methods requires the coefficient and ...

A pathqualityaware peertopeer file sharing protocol for mobile adhoc networks: WiShare
(IEEE, 200909)Peertopeer networks are rather wellstudied and currently there are numerous systems based on peertopeer principles running on the Internet. On the other hand peertopeer networks for mobile adhoc networks have ...
