      A graph theoretic approach to multivariable control system design 

      Schizas, Christos N.; Evans, F. J. (1981)
      A graph theoretic approach is described for the design of multivariable control for large systems as an alternative to geometric methods. An example is given f⊙r a distillation column to demonstrate the technique, with a ...

      Rank-invariant transformations and controllability of large-scale systems 

      Schizas, Christos N.; Evans, F. J. (1980)
      The relevance of structure to the exact determination of rank in large-scale systems is discussed, with particular reference to state transformations and the conditions for controllability (observability). The structural ...

      APL AND GRAPH THEORY IN DYNAMIC SYSTEMS ANALYSIS. 

      Schizas, Christos N.; Evans, F. J. (1981)
      It is demonstrated how well-established graph theoretic results can be exploited in the analysis of large-scale systems, and directed towards questions of design such as controllability and stability. The generalized nature ...

      Data protection issues of integrated Electronic Health Records (EHR) 

      Schiza, Eirini C.; Fakas, Georgios John; Pattichis, Constantinos S.; Petkov, N.; Schizas, Christos N. (Springer Verlag, 2016)
      An Electronic Health Record (EHR) of a patient in perspective maintains the medical history of the citizen electronically in medical databanks serviced locally or is cloud based. The ownership and the access control should ...

      Performance potential of data dependence speculation & collapsing 

      Sazeides, Yiannakis; Vassiliadis, Stamatis; Smith, James E. (IEEE, 1996)
      Two hardware methods for remedying the effects of true data dependences are studied. The first method, dependence speculation, is used to eliminate address generation-load dependences. This is enabled by address prediction ...

      How to compare the performance of two SMT microarchitectures 

      Sazeides, Yiannakis; Juan, T. (Institute of Electrical and Electronics Engineers Inc., 2001)
      In this paper we discuss methods and metrics for comparing the performance of two simultaneous multithreading microarchitectures. We identify conditions under which the instructions-per-cycle metric may be misleading for ...

      The significance of affectors and affectees correlations for branch prediction 

      Sazeides, Yiannakis; Moustakas, Andreas; Constantinides, Kypros; Kleanthous, Marios M. (2008)
      This work investigates the potential of direction-correlations to improve branch prediction. There are two types of direction- correlation: affectors and affectees. This work considers for the first time their implications ...

      Improving branch prediction by considering affectors and affectees correlations 

      Sazeides, Yiannakis; Moustakas, Andreas; Constantinides, Kypros; Kleanthous, Marios M. (2011)
      This work investigates the potential of direction-correlations to improve branch prediction. There are two types of direction-correlation: affectors and affectees. This work considers for the first time their implications ...

      Implicit-storing and redundant-encoding-of-attribute information in error-correction-codes 

      Sazeides, Yiannakis; Özer, E.; Kershaw, D.; Nikolaou, Panagiota; Kleanthous, Marios M.; Abella, J. (2013)
      This paper proposes implicit-storing to extend the logical capacity of a memory array without increasing its physical capacity by leveraging the array's error-correction-codes to infer the implicitly stored bits. ...

      Predictability of data values 

      Sazeides, Yiannakis; Smith, James E. (IEEE Comp Soc, 1997)
      The predictability of data values is studied at a fundamental level. Two basic predictor models are defined: Computational predictors perform an operation on previous values to yield predicted next values. Examples we study ...

      Modeling program predictability 

      Sazeides, Yiannakis; Smith, James E. (IEEE Comp Soc, 1998)
      Basic properties of program predictability - for both values and control - are defined and studied. We take the view that program predictability originates at certain points during a program's execution, flows through ...
