Adjourn state concurrency control avoiding time-out problems in atomic commit protocols
(2008)The use of atomic commit protocols in mobile ad-hoc networks involves difficulties in setting up reasonable timeouts for aborting a pending distributed transaction. This paper presents the non-blocking Adjourn State, a ...

Automatic code generation: A practical approach
(2008)This work contributes in bridging the gap between software design and implementation of component-based systems using software architectures at the modelling/design level and the coordination paradigm at the implementation ...

Design and development of a haptic peg-board exercise for the rehabilitation of people with multiple sclerosis
(Affiliation: Mechanical and Manufacturing Engineering Department, University of Cyprus, P.O. Box: 20537, Nicosia, CyprusAffiliation: Mechanical and Manufacturing Engineering Department, University of CyprusCorrespondence Address: Xydas, E. G.Mechanical and Manufacturing Engineering Department, University of Cyprus, P.O. Box: 20537, Nicosia, Cyprusemail: mep4ex01@ucy.ac.cy, 2007)Peg-in-Hole methods, like the Nine Hole Peg-Board Test (NHPT) and the Perdue board are widely employed for the functional assessment and therapy of the upper limbs of people with Multiple Sclerosis (MS). Such passive devices ...

How many attackers can selfish defenders catch?
(2008)In a distributed system with attacks and defenses, an economic investment in defense mechanisms aims at increasing the degree of system protection against the attacks. We study such investments in the selfish setting, where ...

InAs quantum dots grown by molecular beam epitaxy on GaAs (211)B polar substrates
(2006)InAs nanostructures were grown by molecular beam epitaxy on GaAs (211)B at temperatures between 400-530 °C and growth rates that were varied between 0.1 to 0.02 mono-layers (ML) per second. For temperatures up to 500 °C ...
