An architecture for secure VoiIP and collaboration applications
(2007)VoIP and collaboration Internet applications are a driving force for the use and expansion of the Internet. Current applications usually require end user registration in a central user database, which in turn provides ... 
Artificial Neural Networks and Principal Components Analysis for Detection of Idiopathic Pulmonary Fibrosis in Microscopy Images
(2013)In this study we present a computer assisted image identification and recognition tool that aims to help the diagnosis of idiopathic pulmonary fibrosis in microscopy images. To this end, we use principal components analysis ... 
Bayesian uncertainty quantification and propagation for discrete element simulations of granular materials
(2014)Predictions in the behavior of granular materials using Discrete Element Methods (DEM) hinge on the employed interaction potentials. Here we introduce a data driven, Bayesian framework to quantify DEM predictions. Our ... 
Bifurcations and catastrophes of a twodegreesoffreedom nonlinear model simulating the buckling and postbuckling of rectangular plates
(2007)The nonlinear buckling and postbuckling behavior of rectangular plates in symmetric and antisymmetric modes is reexamined, in the context of Bifurcation and Catastrophe Theories, using a twodegreesoffreedom model, which ... 
Computational fluid dynamics applications to improve crop production systems
(2013)Computational fluid dynamics (CFD), numerical analysis and simulation tools of fluid flow processes have emerged from the development stage and become nowadays a robust design tool. It is widely used to study various ... 
Delineation of management zones in an apple orchard in Greece using a multivariate approach
(2013)Management zone (MZ) delineation is important for the application of Precision Agriculture because farm management decisions are based on it. Several factors were used for the MZ delineation including crop and soil ... 
The effect of infinitesimal damping on the dynamic instability mechanism of conservative systems
(2008)The local instability of 2 degrees of freedom (DOF) weakly damped systems is thoroughly discussed using the LienardChipart stability criterion. The individual and coupling effect of mass and stiffness distribution on the ... 
An experimental study of interface relaxation methods for composite elliptic differential equations
(2008)The recently proposed simulation framework of interface relaxation for developing multidomain multiphysics simulation engines is considered. An experimental study of the behavior of two representative interface relaxation ... 
Extension and evaluation of a model for automatic drainage solution management in tomato crops grown in semiclosed hydroponic systems
(2015)In the present paper, a model previously developed to simulate the course of Na+ accumulation in closed hydroponic systems as a function of plant water consumption was further extended so as to be operative also in semiclosed ... 
Extracting coarsegrained pipelined parallelism out of sequential applications for parallel processor arrays
(2009)We present development and runtime support for building application specific data processing pipelines out of sequential code, and for executing them on a general purpose platform that features a reconfigurable Parallel ... 
Farm machinery management information system
(2015)Management of farming operations is currently rapidly changing toward a systems perspective integrating the surroundings in terms of environmental impact, public entities and documentation of quality and growing conditions. ... 
Farm management information systems: Current situation and future perspectives
(2015)Farm Management Information Systems (FMIS) in agriculture have evolved from simple farm recordkeeping into sophisticated and complex systems to support production management. The purpose of current FMIS is to meet the ... 
Finite Element Analysis of Discrete Circular Dislocations
(2010)The present work gives a systematic and rigorous implementation of (edge type) circular Volterra dislocation loops in ordinary axisymmetric finite elements using the thermal analogue and the integral representation of ... 
Finite element implementation of gradient plasticity models  Part I: Gradientdependent yield functions
(1998)Theories with intrinsic or material length scales find applications in the modeling of sizedependent phenomena such as, for example, the localization of plastic flow into shear bands. In gradienttype plasticity theories, ... 
Finite element implementation of gradient plasticity models  Part II: Gradientdependent evolution equations
(1998)The variational formulation and finite element implementation of a class of plasticity models with gradientdependent yield functions is covered in detail in Part I. In this sequel, attention is focussed upon the finite ... 
A fivepoint penetrometer with GPS for measuring soil compaction variability
(2013)Measuring soil compaction is a factor of interest to monitor soil fertility, which plays an important role in crop production cycle. Soil penetration resistance is the most commonly used method to measure soil compaction. ... 
A flowshop problem formulation of biomass handling operations scheduling
(2013)Currently, the planning of the biomass collection operations is performed relying on the contractor's experience without the use of any dedicated planning tool. It is expected that more explicitly formulated planning tools ... 
A four nation survey of farm information management and advanced farming systems: A descriptive analysis of survey responses
(2011)The aim of this paper is to present the descriptive results of the survey responses that explore the perception of advanced information systems among four European countries: i.e. Denmark, Finland, Germany and Greece. The ... 
Inputoutput decoupling for linear systems with nonlinear uncertain structure
(1996)in this paper the problem of inputoutput decoupling for linear systems with nonlinear uncertain structure, via an independent of the uncertainties static state feedback law, is studied and solved for the first time. The ...
