In the present study, a variable stiffness method (VSM) is revisited for aeroelastic computations with/without thermal effects. Unlike traditional CFD/CSM coupling (TM), which predicts responses by varying freestream conditions (e.g. density, velocity), in VSM can be fixed. The first verified theoretically and adopted to predict nonlinear responses. For computations, applied flutter onset of Is...

Since the huge database of patent documents is continuously increasing, the issue of classifying, updating and retrieving patent documents turned into an acute necessity. Therefore, we investigate the efficiency of applying Latent Semantic Indexing, an automatic indexing method of information retrieval, to some classes of patent documents from the United States Patent Classification System. We ...

This paper proposes an efficient approach for the computation of voltage stability margin (VSM) in a large-scale power grid. The objective is to accurately and rapidly determine the load power margin which corresponds to voltage collapse phenomena. The proposed approach is based on the impedance match-based technique and the model-based technique. It combines the Thevenin equivalent (TE) networ...

In this paper, we target document ranking in a highly technical field with the aim to approximate a ranking that is obtained through an existing ontology (knowledge structure). We test and combine symbolic and vector space models (VSM). Our symbolic approach relies on shallow NLP and on internal linguistic relations between Multi-Word Terms (MWTs). Documents are ranked based on different semant...

Vascular tone, an important determinant of systemic vascular resistance and thus blood pressure, is affected by vascular smooth muscle (VSM) contraction. Key signaling pathways for VSM contraction converge on phosphorylation of the regulatory light chain (RLC) of smooth muscle myosin. This phosphorylation is mediated by Ca(2+)/calmodulin-dependent myosin light chain kinase (MLCK) but Ca(2+)-ind...

Prostacyclin (PGI2) is a key mediator of pulmonary vascular and parenchymal function during late fetal and early postnatal life, and its synthesis in intrapulmonary arteries increases markedly during that period. The rate-limiting enzyme in PGI2 synthesis in the developing lung is cyclooxygenase (COX). To understand better the mechanisms underlying the developmental increase in PGI2 synthesis, ...

Monitoring task performance is crucial in team work in order to ensure equal participation of all team members. However, it may be difficult to implement due to team dynamism. One of the approaches that can be adopted when monitoring group work relies on measuring efficiency of each task performed by the team members. Thus, this paper aims to demonstrate application of Value Stream Mapping (VSM...

Obesity is a risk factor for cardiovascular disease and is associated with increased plasma levels of the adipose-derived hormone leptin. Vascular smooth muscle cells (VSMC) express leptin receptors (LepR); however, their physiological role is unclear. We hypothesized that leptin, at levels to mimic morbid obesity, impairs vascular relaxation. To test this, we used control and VSM-LepR knockout...

Ca 2 is a major determinant of many biochemical processes in various cell types, from the beginning of new life and egg fertilization to the end of life and cell death.1 In vascular smooth muscle (VSM), physiological resting levels of intracellular free Ca concentration ([Ca ]i) in the nanomolar range are necessary to maintain basal vascular tone.2–4 VSM activation is associated with an increas...

OBJECTIVES The aim of this study was to examine utility of appending International Classification of Diseases (ICD) codes from Vital Statistics Mortality (VSM) data to Bureau of Labor Statistics (BLS) Census of Fatal Occupational Injuries (CFOI), and compare occupational event characteristics based on ICD external cause and BLS Occupational Injury and Illness Classification System (OIICS) event...
