Justifying the development of a business intelligence system is challenging when the primary beneficiaries of the system are internal to the company responsible for that development; it is even harder to justify when the system is designed to produce a new service that is radically different than current in-house manufactured products. This case explores the possibility of a tire manufacturer d...

polymeric yarns for reinforcing cement composites have got great interest in all over the world. in this research the performance of bonding between nylon tire cord grad yarns, and one kind of cement composite called fine grained concrete was studied. two kinds of nylon cord yarns, nylon 6 and 66, with different finesse were selected. the durability of yarns with time in alkaline media was inve...

Wireless autonomous sensor systems become steadily standard components in our environment and they become smaller, cheaper and more sophisticated. Energy harvesters fabricated by micro-system technology can realize the autonomy of those systems. An overview of latest results and remaining challenges will be given with the focus on vibration energy harvesters. These harvesters are of specific in...

Keyword Index: Aedes albopictus, tire trap description, surveillance tool, Dominican Republic. With the introduction of Aedes albopictus (Skuse) into the Americas from southeast Asia and Japan (Hawley 1988), many surveillance tools originally used for Aedes aegypti Linn. programs were adopted to monitor the new invading species. In the continental U.S.A., conventional ovitraps (Fay and Eliason ...

In this article, we report the development of a flexible, 3D printable piezoresistive pressure sensor capable of measuring force and detecting the location of the force. The multilayer sensor comprises of an ionic liquid-based piezoresistive intermediate layer in between carbon nanotube (CNT)-based stretchable electrodes. A sensor containing an array of different sensing units was embedded on t...

We present a density-functional theory study of finite-size effects in stoichiometric and nonstoichiometric BaTiO3 nanowires of varying cross-sectional sizes and sidewall terminations. The tendencies for axial, transverse, and toroidal ferroelectric polarization instabilities in these nanowires have been characterized and possible driving forces underlying these behaviors have been identified. ...

We consider the nature of thermally stratified flow in a closed cylinder rotating about the direction of gravity under conditions appropriate for terrestrial laboratory experiments. Motion is driven by centrifugal buoyancy, with outflow near the cold disk and inflow near the hot disk. Although similarity solutions for the infinite disk open-geometry problem exist and are easily found, even anal...

We have simulated the effect of sidewall roughness in photonic-crystallike structures with different vertical refractive-index contrast. We treated the scattering off a sidewall irregularity as a radiating dipole excited by the incident waveguide mode. We show that the loss that is due to this scattering is significantly larger for structures with a low refractive-index contrast (such as GaAs/A...

Since Bodewadt's (1940) seminal work on the boundary layer flow produced by a fluid in solid-body rotation over a stationary disk of infinite radius there has been much interest in determining the stability of such flows. To date, it appears that there is no theoretical study of the stability of Bodewadt's self-similar solution to perturbations that are not self-similar. Experimental studies ha...

The effect of a nonzero sidewall angle on the performance of multiple layer fishnet-structure one to three functional layers negative index metamaterials is evaluated experimentally. The fabrication-induced sidewall angle results in a bianisotropy inhomogeneous asymmetry that is significant at optical frequencies. Good agreement is obtained between the experimental transmission and reflectance ...
