Since 1970, the share of income spent on housing grew along with incomes and the relative price of housing. This rising share is consistent with housing being a necessity when demand is sufficiently price inelastic. We estimate housing demand parameters using compensated and uncompensated frameworks over space and time, testing restrictions imposed by demand theory and household mobility. Estim...

Molecular dynamics simulations using Tersoff potential were performed in order to study the evolution of atomic packing structures, loading states on atoms, and tensile tests, as well thermal properties Si/Ge core–shell nanowires with different structures ratios at temperatures. Potential energy pair distribution functions indicate structural features these During uniaxial testing along wire ax...

Elasticity is the ability of a software system to dynamically scale the amount of the resources it provides to clients as their workloads increase or decrease. Elasticity is praised as a key advantage of cloud computing, where computing resources are dynamically added and released. However, there exists no concise or formal definition of elasticity, and thus no approaches to quantify it have be...

Elasticity is a key property of cloud computing environments and one of the features which distinguishes this paradigm from other ones. An elasticity metric could be used to define and to monitor Service Level Agreements (SLAs), to compare and to benchmark different cloud providers or to improve provisioning and management decisions in real time if it could be measured with some simple procedur...

Modulus of elasticity of flapper valve material is an important parameter for compressor design since it can affect efficiency and life time of the compressor. Modulus of elasticity is usually considered as a material constant. Actually, it can vary with material orientations and conditions and even environments such as temperature will also affect this value. Therefore, the parameters that can...

Series elastic actuation that takes inspiration from biological muscle-tendon units has been extensively studied and used to address the challenges (e.g. energy efficiency, robustness) existing in purely stiff robots. However, there also exists another form of passive property in biological actuation, parallel elasticity within muscles themselves, and our knowledge of it is limited: for example...

Objective: Skin aging occurs not only due to age but is influenced by various environmental factors such as lifestyle, pollution, and excessive exposure UV rays. Secretomes can act antiaging agents that stimulate collagen biosynthesis naturally in the skin. This study aims create a cream containing 5% secretome with essential oil, dermatological examination, Fibroblast Growth Factor (FGF) check...

Abstract Background Bending tests offer technical advantages when material testing is performed to determine the modulus of elasticity. In biomechanical studies, beam-like cortical bone specimens subjected flexural loading are usually characterized by nonuniform cross-sectional properties along beam axis and a comparatively large spatial variation local properties. Objective A suitable evaluati...

Conventional diagnostic ultrasound images portray differences in the acoustic properties of soft tissues, whereas ultrasound-based elasticity images portray differences in the elastic properties of soft tissues (i.e. stiffness, viscosity). The benefit of elasticity imaging lies in the fact that many soft tissues can share similar ultrasonic echogenicities, but may have different mechanical prop...
