The oblique sinus is a cul-de-sac located posterior to the atria (particularly the left atrium [LA] in the region between the four PVs) and anterior to the esophagus and descending aorta. The oblique sinus is an invertedU-shaped pericardial reflection bordered by the right PVs and IVC on ...
To ensure maximum yield of window-integrated PVs, external glass layers that cover solar cells must be as transparent as possible to let all the light radiation in. Highly transparent low-iron glass panes, however, still reflect a part of the incoming radiation, in particular solar rays coming...

Security is a familiar term to most people; however, the term security has multiple meanings, and the intended meaning is not always clear [2,13,14,15]. The definition of security is imprecisely differentiated from similar terms, such as safety [16,17], certainty and dependability [2,18,1...
In particular, the simulators are flown by experienced test pilots that tend to adapt very quickly to new aircraft, and they may unconsciously compensate for deficiencies in the PVS system without unmasking the A/RPC event. However, it is also recognised in the literature that simulators can ...
In the past, target values were mainly developed based on technical and/or economic feasibility or by statistically deriving “best in class” values according to the “less is more” approach [14]. These were different depending on the type of building and use. The top-down approach uses a...
The technologies used for these applications include renewable DGs such as wind, PVs, fuel cells (FCs), and combined heat and power (CHP). The presence of DG in the distribution system may improve system reliability as a result of supplying loads in islanded operation. The islanded operation ...
The PVs that are based on other materials than on silicon would follow in applications in the next years, mainly in the built sector. The conversion rate of solar radiation into electricity by PVs depends on cell type and is between 5% and 20%. Thus, the greater part of the absorbed ...
In the water bath, PP and PE will float while other polymers such as PET, PS and PVS will sink. The sink fraction passes through a powerful overhead magnet to a mechanical dryer to remove ferrous residues and the material is a mixture of technical plastics ready to be used as a ...
All these considerations were taken into account to investigate the thermal performance of the system combined by PVs and TSCs. Summers [25] used TRNSYS to predict energy savings resulting from the active solar gain, the recaptured wall heat loss and reduced wall heat loss. Parametric studies for...
