Purpose: To build a factor model of vibrodynamic loading influence on pipeline reliability based the results laboratory tests carried out taking into account amplitude-frequency characteristics vibration process operating pipeline, obtained during full-scale at railway station. On basis to determine most significant factors affecting pipelines under action and propose ways improve their reliabi...

In recent years there has been very extensive use of power electronic devices, which result in harmonic proliferation in the power distribution system. In this paper, as per IEEE C 57.110 standards, procedure to calculate total loss in the distribution transformer under non-linear distortion environment is proposed. The power factor capacitor performance under non-linear load conditions is also...

It is shown that if the displacement field and stress intensity factor are known as functions of crack length for any symmetrical load system acting on a linear elastic body in plane strain, then the stress intensity factor for any other symmetrical load system whatsoever on the same body may be directly determined. The result is closely related to Bueckner's [1] "weight function". through whic...

In rigid plastic analysis one of the most widely applicable methods that is based on the minimum principle, is the combination of elementary mechanisms which uses the upper bound theorem. In this method a mechanism is searched which corresponds to the smallest load factor. Mathematical programming can be used to optimize this search process for simple fra...

BACKGROUND Advancing patient safety during handoffs remains a public health priority. The application of cognitive load theory offers promise, but is currently limited by the inability to measure cognitive load types. OBJECTIVE To develop and collect validity evidence for a revised self-report inventory that measures cognitive load types during a handoff. METHODS Based on prior published wo...

Purpose: The managers' professional development is one of the effective factors in improving the position of organizations in comparison with other organizations. Therefore, the present study was conducted with the aim of providing a model of educational managers' professional development in the banking industry. Methodology: This research in terms of purpose was applied and in terms of implem...

alzheimer's disease (ad) is a genetically heterogeneous neurodegenerative disease and late-onset type (load) is the most common form of dementia affecting people over 65 years old. calhm1 (p86l) encodes a transmembrane glycoprotein that controls cytosolic ca2+ concentrations and aß levels and p86l polymorphism in this gene is significantly associated with load in independent case controls in a ...

this paper presents a new control method for a three-phase four-wire unified power quality conditioner (upqc) to deal with the problems of power quality under distortional and unbalanced load conditions. the proposed control approach is the combination of instantaneous power theory and synchronous reference frame (srf) theory which is optimized by using a self-tuning filter (stf) and without us...
