This article is the first part of a review of investigations carried out until about 1990 into the role of mechanical ventilation in reducing wound sepsis in hospitals. It deals with the design of mechanical ventilation systems to reduce airborne microbe-carrying particles (MCPs), and mainly discusses unidirectional airflow (UDAF) systems. The second part will deal with the effect of mechanical...

This paper describes an ontology model (conceptual model) based on the ITU-T Recommendation G.805 for transport network architectures. The goal is to take a step forward to the autonomic applications for transport network operation and management. Besides the conceptual model description and explanation, including its main elements (classes, properties and constraints), this paper also includes...

It has been shown that in decision making evaluations of evidence and attributes are modified. In three studies it was investigated if this finding of coherence shifts generalizes to real-world probabilistic inference decisions which are made from given probabilistic cues. Using a within-subjects design, cue validities were measured before, after (Exp. 1) and during decision making (Exp. 2 & 3)...

Carbon fiber-reinforced multi-layered pyrocarbon-silicon carbide matrix (C/C-SiC) composites are widely used in aerospace structures. The complicated spatial architecture and material heterogeneity of C/C-SiC composites constitute the challenge for tailoring their properties. Thus, discovering the intrinsic relations between the properties and the microstructures and sequentially optimizing the...

"Observer based model predictive control of the water Based painting drying using a humidity profile soft sensor and a temperature measurement", This paper deals with the model predictive control of an infrared drying process of a water based epoxy-amine painting. During the drying cycle, the control problem is to optimize the use of the process under constraints. This approach is based on a no...

The Eclipse Modeling Framework (EMF) and its meta-meta model Ecore support uni-directional and bi-directional references. It is quite common that references are defined uni-directionally only because of saving storage space or separating meta models, which is problematic when implementing Object Constraint Language (OCL) constraints that require navigation against the direction of unidirectiona...

The paper derives a robust networked controller design method for systems with saturation where the delay is large and unknown, as in unidirectional flow-control. A classical linear robust criterion is first formulated in terms of the sensitivityand complementary sensitivity functions. Based on the Popov-criterion a new asymptotic constraint is derived, which specifies the minimum amount of low...

In this study, a novel numerical method is proposed for determination of mode-I interlaminar fracture toughness, GIc, in multi-directional (MD) double cantilever beam (DCB) specimens using fracture properties of unidirectional DCB specimens. Two factors, β and Dc are defined to minimize the undesirable effects on strain energy release rate. β describes the difference between maximum and average...

this paper investigates the relationship between total energy consumption and gdp in six countries of the middle east , including iran,pakistan,saudi arabia,oman,bahrain and the united arab emirates. the data are annual and spanning the period 1980-2012.we employed hsiao’s (1981) methodology to examine causality relation between total energy consumption and gdp.the empirical findings show a uni...

ABSTRACT Cable-actuated parallel manipulators combine benefits of large workspaces, significant payload capacities and high stiffness by virtue of the cable actuation. However, redundant/surplus cables are required to overcome the unidirectional nature of forces exertable by cables. This leads to ...
