The development of any particular analytical or preparative applications using electrochemical techniques in microfluidic devices requires integration of microelectrodes. This involves detailed predictions for optimizing the design of devices and selecting the best hydrodynamic conditions. For this purpose, we undertook a series of works aimed at a precise investigation of mass transport near e...

Virtual Private Network (VPN) protects information systems in enterprise organizations by building a security tunnel between the headquarters and branches, or from the headquarters to suppliers and customers. Proper and effective implementation can be evaluated by considering organizational effects and enterprise objectives. In this paper a research model is proposed to evaluate the performance...

OLAP applications make use of fast indexes and materialization of data. Most research treats just one topic. Either the materialized values or the design of index structures are considered. This paper examines a possible combination of both techniques. The R -tree is taken as an example of a multi-dimensional index structure. Aggregated data is stored in the inner nodes of the index structure i...

This paper revisits the recent works of Suwignjo, Bititci and Carrie (SBC) (Int. J. Prod. Econom. 64 (2000) 231) and Bititci, Suwignjo and Carrie (BSC) (Int. J. Prod. Econom. 69 (2001) 15). We show how a generalizable analytical hierarchy technique based on Saaty’s systems-with-feedback approach, also known as the analytical network process (ANP), can be applied, as an alternative methodology, ...

Data warehouse and OLAP are core aspects of business intelligence environments, since the former store integrated and time-variant data, while the latter enables multidimensional queries, visualization and analysis. The bitmap join index has been recognized as an efficient mechanism to speed up queries over data warehouses. However, existing OLAP tools does not use strictly this index to improv...

This paper presents a multicriteria model for the bank performance evaluation. The model is based on the AHP method (Analytical Hierarchy Process), and it enables the integration of the quantitative data (measured by selected financial ratios) and qualitative data by which the bank features and some internal and external environment factors are described. The financial ratios used in the model ...

Basketball is constantly booming with China’s material and cultural levels development. And basketball reserve personnel quantity and quality stand for a nation basketball level. On the current all countries basketball levels rapidly development situation in the world, cultivation of basketball reserve personnel has become an indispensible condition to be in an invincible position in intense ba...

We propose a simple microfluidic device able to separate submicron particles (critical size ∼0.1 μm) from a complex sample with no filter (minimum channel dimension being 5 μm) by hydrodynamic filtration. A model taking into account the actual velocity profile and hydrodynamic resistances enables prediction of the chip sorting properties for any geometry. Two design families are studied to obta...

Organizational performance evaluation is a very vital and sensitive process in any industry. One of the most crucial aspects of performance assessment is consideration of financial performance evaluation. In this kind of evaluation, we face many criteria and index to performing and also designing a comprehensive and effective model. Thus, this situation can be regarded as a fuzzy multiple crite...

A balanced scorecard (BSC) is a management decision tool intended to be the corporate performance measurement. It also can play an important role in transforming an organization’s mission and strategy into a balanced set of integrated performance measures. Assigning suitable weight to each level of balanced scorecard is crucial to conduct performance evaluation effectively. In this research a c...
