Representation of lattices with modal operators in two-sorted frames
(2019)We study general lattices with normal unary operators for which we prove relational representation and duality results. Similar results have appeared in print, using Urquhart's lattice representation, by the second author ... -
Riccati equation solution method for the computation of the extreme solutions of X + A* X-1 A = Q and X - A* X-1 A = Q
(2009)Algebraic and recursive methods for computing the extreme solutions of the matrix equations X + A* X-1 A = Q and X - A* X -1 A = Q are presented in this paper. The proposed algorithms are based on the solution of the ... -
Scheduling independent tasks in heterogeneous environments under communication constraints
(2006)With the advent of the Grid, task scheduling in heterogeneous environments becomes more and more important. Of particular interest is the fact that especially in scientific experiments a non negligible amount of data must ... -
Seismic analysis and design of industrial pressure vessels
(2011)The present paper focuses on the seismic analysis and design of horizontal-cylindrical and vertical-cylindrical pressure vessels. First, a comparison of the seismic provisions in ASME B&PV code and in EN 13445-3 is conducted ... -
Seismic strength evaluation of reinforced concrete shear walls with cracks, using the notion of fractal geometry
(2011)Shear walls play an important role to the seismic strength of modern seismic resistant structures. They are designed so that they have significant bending and shear strengths and ductility. However, existing structures ... -
Simulation of industrial elbow response under strong cyclic loading
(2011)Elbow components are widely used in industrial facilities as parts of piping/tubing systems. Their performance under severe loading conditions may be critical for the structural integrity of an industrial facility In the ... -
Simulation of intercritical annealing in low-alloy TRIP steels
(2000)A coupled thermodynamic/kinetic calculation of austenite formation during intercritical annealing of low-alloy TRIP steels is presented. The simulation was performed with the use of Dictra computational kinetics software, ... -
Structural optimization of a wing body with uncertain aerodynamic loads
(2015)An algorithm for the structural optimization of wing body structures is presented in this paper. The structural analysis for the computation of displacements and stresses within the wing body is based on a finite volume ... -
Study of the influence of seismic action on the construction cost of the load-bearing structure of a ten-storey R/C building
(2021)Greece is divided into three seismic hazard zones ZI, ZII, ZIII. In the present research work, the same building in the three seismic zones of Greece is modeled, analysed and dimensioned and then the construction cost of ... -
System identification of a R/C bridge based on ambient vibrations and 3D numerical simulations of the entire soil-structure system
(2011)The scope of this paper is to identify the parameters affecting the dynamic response of an existing R/C bridge, based on low ambient amplitude vibration measurements and numerical predictions using complex finite element ... -
T-RECs: Rapid and large-scale detection of recombination events among different evolutionary lineages of viral genomes
(2017)Background: Many computational tools that detect recombination in viruses are not adapted for the ongoing genomic revolution. A computational tool is needed, that will rapidly scan hundreds/thousands of genomes or sequence ... -
Tabu-based heuristic approach for optimization of network evacuation contraflow
(2006)In urban evacuations, especially in response to an expected disaster, capacity reversibility (also known as contraflow) has been considered a workable strategy to reduce traffic congestion and to meet evacuation time ... -
Ultrasonic monitoring of bone fracture healing
(2008)Quantitative ultrasound has attracted significant interest in the evaluation of bone fracture healing. Animal and clinical studies have demonstrated that the propagation velocity across fractured bones can be used as an ...
