This paper concentrates on the quality management of a project by applying network approaches and statistics methods. A large-scale project can be modeled as a project network. This paper tries to schedule the duration of the project by applying the approaches in network analysis in case the activity duration and the corresponding cost are both arbitrary random variables with a probability dist...

The purpose of this study was to develop a psychometric questionnaire in order to evaluate the educational web site “Youth 2004” considering the attitudes and the perceptions of Greek Australian students. In addition, the differences among the age and sex were also investigated. Participants were 317 Greek Australian students, between the ages from 12-17 years old. Data was collected using an o...

We consider an electricity consumer equipped with a perfect battery, who needs to satisfy a non-elastic load, subject to external control signals. The control imposes a time-varying upper-bound on the instantaneous energy consumption (this is called “Demand-Response via quantity”). The consumer defines a charging schedule for the battery. We say that a schedule is feasible if it successfully ab...

This paper describes a systematic approach to the enumeration of 'non-crossing' geometric configurations built on vertices of a convex n-gon in the plane. It relies on generating functions, symbolic methods, singularity analysis, and singularity perturbation. Consequences are both exact and asymptotic counting results for trees, forests, graphs, connected graphs, dissections, and partitions. Li...

Studies show that the unsatisfactory results in software projects are often related to the lack of training and commitment of human resources. In this context, this paper presents a proposal that integrates the employment of the practices proposed by the Personal Software Process (PSP) into the context of project management, aiming to support the self-improvement and commitment of each human re...

These studies, exploring the effects of personality on team productivity, had a limited focus by considering only one or two teams, or examining one or two personality dimensions. While the previous studies are insightful, they only establish the foundation for further study [10]. Moreover, previous studies were conducted on large software teams; the results of these studies are not generalizab...

This note describes the performance of the calorimeter clustering algorithms used for ATLAS, and which provide inputs for particle identification. ATLAS uses two principal algorithms. The first is the “sliding-window” algorithm, which clusters calorimeter cells within fixed-size rectangles; results from this are used for electron, photon, and tau lepton identification. The second is the “topolo...

An extended cloud-clustering method to assess the seasonal variation of clouds is applied to five CMIP5 models. The seasonal variation of the total cloud radiative effect (CRE) is dominated by variations in the relative frequency of occurrence of the different cloud regimes. Seasonal variations of the CRE within the individual regimes contribute much less. This is the case for both observations...

This paper presents a list-scheduling algorithm for graphs with data and control dependencies. We assume that tasks are partitioned between hardware resources as scheduling takes place after partitioning in our co-synthesis tool. Control dependencies are introduced by if statements, and model complementary functionalities. A detailed discussion of our algorithm is presented. Extensive experimen...

The aim of this paper is to characterize the moveability of fully-parallel manipulators in the presence of obstacles. Fully parallel manipulators are used in applications where accuracy, stiffness or high speeds and accelerations are required [1]. However, one of its main drawbacks is a relatively small workspace compared to the one of serial manipulators. This is due mainly to the existence of...
