  • Development of hybrid MPI+UPC parallel programming model 

    Authors:Öztürk, Elif
    Publisher and Date:(Kadir Has University, 2011)
    Parallel Computing is a form of computation that divides a large set of calculations into tasks and runs on multi-core machines simultaneously. Today, Message Passing Interface (MPI) is the most widely used parallel programming paradigm that provides programming both for symmetric multi-processors (SMPs) which consists of shared memory nodes with several multi-core CPUs connected to a high speed network and among nodes simultaneously. Unified Parallel C (UPC) is an alternative language that supports ...

  • Global alignment of metabolic pathways and protein-protein interaction networks 

    Authors:Abaka, Gamze
    Publisher and Date:(Kadir Has University, 2014)
    Metabolic pathways and protein interaction networks are essential at almost every function for living organisms. Simply, while reactions produce life energy within cells, protein interaction networks provide biological functions. Also, abnormal reactions or interactions cause various disorders. Thus, in bioinformatics, most of the studies are based on these networks in order to find hopeful results for these disorders and biological challenges. Solving alignment problem is one of these studies ...

  • Hub analysis of health information platform from a network science perspective 

    Authors:Çalışan Özyurt, Şeyma
    Publisher and Date:(Kadir Has University, 2015)
    Online information platforms such as social networking applications are subject to examination of the underlying interactions as a network. Managers of these platforms are often unaware what constitutes the very idea of network growth. Conventional web and social analytics metrics are not adequate to surface the intriguing interplays among individuals interacting on these platforms. Thus, the challenge for managers is to know what underlies growth of the network on these platforms. The goal of ...

    Authors:Alp, Ebru
    Publisher and Date:(Kadir Has University, 2015)
    Nowadays, smartphone market penetration continues to grow with developing technology. Accordingly, position detection in closed areas has become an important research area. For instance; finding a direct route to the gate based on location at an airport, determining a route to the destination that could be a shop or cafe at a shopping center or informing about sales discount to increase sales using location are several applicable areas of position estimation. In the thesis, I developed triangulation ...

  • Message-passing based algorithm for the global alignment of clustered pairwise PPI networks 

    Authors:Yenigün, Doğan Yiğit
    Publisher and Date:(Kadir Has University, 2013)
    Constrained global network alignments on pairwise protein-protein interaction (PPI) networks involve matchings between two organisms where proteins are grouped together in a great number of clusters, produced by algorithms that seek functionally ortholog ones and these organisms are represented as graphs. Unlike balanced global network alignments, this has not gained much popularity in bioinformatics. Only a few methods have been proposed thus far; by assuming specific structures of networks ...
