The aim of this review was to assess the current viable technologies for wireless power delivery and data transmission through metal barriers. Using such technologies sensors enclosed in hermetical metal containers can be powered and communicate through exterior power sources without penetration of the metal wall for wire feed-throughs. In this review, we first discuss the significant and essen...

Several research studies have identified window-wall interfaces as one of the major sources water ingress through building envelopes. Window-wall can either be sealed by means face-sealed or drained sealing systems. In general, it is assumed that show an improved rainwater resistance compared to interfaces. However, only a limited number found in literature evaluating watertightness performance...

Traditional Chinese wood residences consist of timber frames with masonry infill walls or other types infill, representing valuable heritage. A field investigation traditional village dwellings in northern China consisting mud and stone was conducted. Their construction characteristics are reported, static cyclic tests were performed on two full-size wood-stone hybrid different configurations (...

Ω(R) d −→ Ω(R) d −→ Ω(R) d −→ Ω(R), where Ωi(R) is the space of differential forms of degree i = 0, 1, 2, 3 on the space R over the ring of functions A = {f : R → R | f ∈ C(R)}. In the consideration, which follows, we give definitions of the first-order differential operations. Let us notice that one-dimensional spaces Ω0(R) and Ω3(R) are isomorphic to A and let φ0 : Ω (R) → A, φ3 : Ω (R) → A b...

We define a new version of the exterior derivative on the basic forms of a Riemannian foliation to obtain a new form of basic cohomology that satisfies Poincaré duality in the transversally orientable case. We use this twisted basic cohomology to show relationships between curvature, tautness, and vanishing of the basic Euler characteristic and basic signature.

OBJECTIVE To evaluate the value of conventional ultrasound and contrast-enhanced ultrasound (CEUS) in determining the severity of active Crohn's disease. METHODS Thirty-seven patients who were considered to be in active period of Crohn's disease were included. Conventional ultrasound was employed to measure the thicknesses of interior, exterior and the whole bowel walls. Qualitative and quant...
