The combination of components from different algorithms is currently one of the most successful trends in optimization. The hybridization of metaheuristics such as ant colony optimization, evolutionary algorithms, and variable neighborhood search with techniques from operations research and artificial intelligence plays hereby an important role. The resulting hybrid algorithms are generally lab...

Processes are the core of organisations. Business Process Management (BPM) argues organisations can gain competitive advantage by improving and innovating their processes through a holistic process-oriented view. An organisation can be more or less process-oriented depending on their experience in applying process thinking for better results. The aim of this paper is to define a framework for i...

Purpose The pandemic emphasised the importance for society of “hidden” workforce – cleaners, delivery drivers, security guards or hospital porters. This paper explores well-being low-status expatriates in international workplace exemplified by United Arab Emirates (UAE). is one first studies examining people at bottom pyramid, living difficult circumstances, and undertaking work that hard somet...

This paper presents and compares two views of the theory of rough sets. The operator-oriented view interprets rough set theory as an extension of set theory with two additional unary operators. Under such a view, lower and upper approximations are related to the interior and closure operators in topological spaces, the necessity and possibility operators in modal logic, and lower and upper appr...

Aim of Study. To assess the feasibility of a new proposed maneuver "RATLe-90" using real-time three-dimensional transesophageal echocardiography (RT-3DTEE) for anatomically oriented visualization of the interatrial septum (IAS) in guiding the transseptal puncture TSP. Methods. The study included 20 patients (mean age, 60.2 ± 6.7 years; 60% males) who underwent TSP for different indications. RT-...

View materialization is known to be a valuable technique for performance optimization in relational databases, and much work has been done addressing the problem of consistently maintaining relational views under update operations. However, little progress has been made thus far regarding the topic of view materialization in object-oriented databases (OODBs). In this paper, we demonstrate that ...
