The formation of oxide film on the surface of aluminium melts, i.e. bifilms, are known to be detrimental when they are incorporated into the cast part. These defects causes premature fractures under stress, or aid porosity ...

Teachers with high job satisfaction become more effective and productive by showing high performance and positively affecting student and school outcomes. This study investigates the relationship between school principals’ ...

In this paper, we propose an enhanced feature selection algorithm able to cope with feature drift problem that may occur in data streams, where the set of relevant features change over time. We utilize a dynamic ...

This work presents a methodology to obtain Dynamic User Equilibrium (DUE) over a road network considering the exhausted gas effect of motorized traffic. On purpose, three emission models are integrated to the traffic ...

In this study, oxide coatings produced on commercially pure Al via 40-min microarc oxidation process in electrolytes containing Na2SiO3, KOH and α-Al2O3 powder were characterized by SEM-EDS, profilometry, XRD and ...

Hybrid composite materials combine the advantages of two or more reinforcement materials and may contain unique physical, mechanical and tribological properties that cannot be achieved with any other materials. In ...

Values education is a process that starts in family and continues at education institutions. It is considered that individuals who form society should have main value judgments to share common social life and to live in ...

We mimic bacterial learning and memory abilities in tungsten based two-sided single layers of WSeO, WSeS, WSeSe, and WSeTe, where the thickness of the material represents the growth in time. We aim to create a quantum ...

Course timetables are often rendered infeasible due to unexpected changes in requirements and must be repaired. Given an initial timetable, planners prefer a repaired timetable whose quality is worsened as little as possible ...

Let R be an arbitrary ring with identity and M a right R-module with S = EndR(M). The module M is called reduced if for any m ∈ M and f ∈ S, fm = 0 implies fM ∩ Sm = 0. In this paper, we investigate properties of ...
