    • Multirelational k-anonymity 

      Nergiz, M.E.; Clifton, C.; Nergiz, A.E. (2009)
      k-Anonymity protects privacy by ensuring that data cannot be linked to a single individual. In a k-anonymous data set, any identifying information occurs in at least k tuples. Much research has been done to modify a ...
    • News releases and stock market volatility: intraday evidence from borsa Istanbul 

      Solakoglu, M. N.; Demir, N. (Elsevier Inc., 2015)
      In this study, we investigate the effect of public information arrival on return volatility for Borsa Istanbul (BIST) using intraday, 60-min returns between October 3, 2013 and March 31, 2014. Stock return and return ...
    • Not all firms react the same to exchange rate volatility? A firm level study 

      Tunc C.; Solakoglu, M. N. (Elsevier Inc., 2017)
      This article investigates the effect of exchange rate volatility on the exporting behavior of firms using a very rich Turkish firm-level data for the period of 1989–2013. The estimation results show that although exchange ...
    • Number guessing 

      Sezin, F.; Sezgin, F. (Australian Association of Mathematics Teachers Inc., 2009)
    • On a conjecture of Ilmonen, Haukkanen and Merikoski concerning the smallest eigenvalues of certain GCD related matrices 

      Altinişik, E.; Keskin, A.; Yildiz, M.; Demirbüken, M. (Elsevier Inc., 2016)
      Let Kn be the set of all n×n lower triangular (0,1)-matrices with each diagonal element equal to 1, Ln={YYT:Y ∈ Kn} and let cn be the minimum of the smallest eigenvalue of YYT as Y goes through Kn. The Ilmonen-Haukkanen-Merikoski ...
    • On determining cluster size of randomly deployed heterogeneous WSNs 

      Sevgi, C.; Koçyiğit, A. (IEEE, 2008)
      Clustering is an efficient method to solve scalability problems and energy consumption challenges. For this reason it is widely exploited in Wireless Sensor Network (WSN) applications. It is very critical to determine ...
    • On Lempel-Ziv complexity of sequences 

      Doǧanaksoy, A.; Göloǧlu, Faruk (Springer, Berlin, Heidelberg, 2006)
      We derive recurrences for counting the number a(n, r) of sequences of length n with Lempel-Ziv complexity r, which has important applications, for instance testing randomness of binary sequences. We also give algorithms ...
    • On non-cooperative genomic privacy 

      Humbert, M.; Ayday, Erman; Hubaux J.-P.; Telenti, A. (Springer, Berlin, Heidelberg, 2015)
      Over the last few years, the vast progress in genome sequencing has highly increased the availability of genomic data. Today, individuals can obtain their digital genomic sequences at reasonable prices from many online ...
    • On the analysis of expected distance between sensor nodes and the base station in randomly deployed WSNs 

      Sevgi, C.; Ali, S.A. (Springer Verlag, 2014)
      In this study, we focus on the analytical derivation of the expected distance between all sensor nodes and the base station (i.e., E[dtoBS]) in a randomly deployed WSN. Although similar derivations appear in the related ...
    • On the statistical Analysis of Feigenbaum Constants 

      Sezgin, F.; Sezgin, T. M. (Elsevier, 2006-11)
      We present statistical analysis of blocks in the binary expansions of Feigenbaum constants a and d for the logistic map. The analysis is carried out on both 1016 and 3400 bit expansions. A w2 test is applied for lumping ...
    • Operational risk and stock market returns: evidence from Turkey 

      Solakoglu, M. N.; Kose, K. A. (John Wiley and Sons, 2011)
      Following several high-severity, low-frequency events in the financial sector, operational risk has gained importance both for regulators and managers of financial sector firms during the last decade. The banking sector ...
