Users of Business Intelligence (BI) systems have started to demand more flexible systems in which they could be empowered to serve themselves – self-service BI. In this paper we aim at explaining how such development influences designers of BI solutions and how it impacts the design situation. To say something about this we adapted the PACT (People, Activity, Context, Technology) framework on t...

This paper describes the use of a system of semantic rules to generate noun compounds, vague or polyse-mous words, and cases of metonymy. The rules are bi-directional and are used by the understanding system to interpret the same constructions.

This paper presents a novel bi-objective manpower scheduling problem that minimizes the penalty resulted from employees’ assignment at lower skill levels than their real skill and maximizes employees’ utility for working at a special skill level in some shifts or on some days. Employees are classified in two specialist groups and three skill levels in each specialization. In addition, the prese...

This paper presents the study of the optimized bi-dimensional wood structures, truss type, applying the method of genetic algorithms. Assessment is performed by means of a computer program called OPS (Optimization of Plane Structures). The purpose is to meet the optimum geometric configuration taking into account the volume reduction. Different strategies are considered for the positioning of d...

This paper reports the rapid melt quenching technique preparation for the new family of bismuth-lead germanate glass (BPG) systems in the form of (GeO(2))(60)-(PbO)(40-) (x)-(½Bi(2)O(3))(x) where x = 0 to 40 mol%. Their densities with respect of Bi(2)O(3) concentration were determined using Archimedes' method with acetone as a floatation medium. The current experimental data are compared with t...

BaBiO3 is a material where formally Bi 4+ ions with the half-filled 6s-states form the alternating set of Bi and Bi ions resulting in a charge ordered insulator. The charge ordering is accompanied by the breathing distortion of the BiO6 octahedra (extension and contraction of the Bi-O bond lengths). Standard Density Functional Theory (DFT) calculations fail to obtain the crystal structure insta...

Business Intelligence (BI) is the ability for an organization to collect, maintain, and organize data and information to provide historical, current and predictive views of operations. Cloud Computing concepts promise new options for an internet based resourcing of hardware and software. Cloud BI Portal will provide a utility model of computing with lower entry and maintenance cost and multiple...

BACKGROUND Scavenger receptor class B type I (SR-BI) is expressed in macrophages, where it has been proposed to facilitate cholesterol efflux. However, direct evidence that the expression of macrophage SR-BI is protective against atherosclerosis is lacking. In this study, we examined the in vivo role of macrophage SR-BI in atherosclerotic lesion development in the apolipoprotein (apo) E-deficie...

Business Intelligence and Analytics (BI&A) is the process of extracting and predicting business-critical insights from data. Traditional BI focused on data collection, extraction, and organization to enable efficient query processing for deriving insights from historical data. With the rise of big data and cloud computing, there are many challenges and opportunities for the BI. Especially with ...

Business Intelligence (BI) project failure rates are high and expected benefits are not always achieved when implementing a BI solution in an organization. Failure is characterized by recurring challenges that remain largely unresolved. Could a better understanding of BI and its challenges emerge by taking a step back to examine how BI is understood? To answer this overarching research question...
