Previous constant-parameter demand models have estimated generic advertising elasticities for cheese to be below that for fluid milk. We relax this assumption, allowing for generic advertising response to vary over time. Cheese advertising elasticities were found below fluid milk up until the mid-1990s; average elasticities since have been similar. A benefit-cost ratio of the farmer-funded gene...

The p-i-n carbon nanotube (CNT) devices suffer from low ON/OFF current ratio and small saturation current. In this paper by band bending engineering, we improved the device performance of p-i-n CNT field effect transistors (CNTFET). A triple gate all around structure is proposed to manage the carrier transport along the channel. We called this structure multi-segment gate (MSG) CNTFET. Band to ...

Cells that make up the bodychr('39')s tissues are usually three-dimensional architecture, the threedimensional culture system enables cells to create natural and in vivo interactions which is an ideal environment for 3D (Three-dimensional) cell growth and issues such as exchange of similar food exchanges inside Capillary in living tissue. In tissue engineering discussion, cell scaffolding is hi...

natural vibration analysis of plates represents an important issue in engineering applications. in this paper, a new and simplify method for vibration analysis of circular and rectangular plates is presented. the design of an effective robust controller, which consistently attenuates transverse vibration of the plate caused by an external disturbance force, is given. the dynamics of the plate i...

Knowledge Engineering was in the past primarily concerned with building and developing knowledge-based systems, an objective which puts Knowledge Engineering in a niche of the world-wide research efforts at best. This has changed dramatically: Knowledge Engineering is now a key technology in the upcoming knowledge society. Companies are recognizing knowledge as their key assets, which have to b...

The increasing complexity of today’s embedded systems and the increasing demand for higher quality require a comprehensive engineering approach. The model-based engineering approach that has been developed in the project SPES 2020 (Software Platform Embedded Systems) is intended to comprehensively support the development of embedded systems in the future. The approach allows for specifying an e...

This paper aims to study the influence of soil-structure interaction on plastic energy demand spectra directly derived from the energy-balance equations of soil-shallow-foundation structure with respect to an ensemble of far-field strong ground motions obtained from Pacific Earthquake Engineering Research (PEER) database and recorded on alluvium soil. The superstructure is modeled as a single-d...

Zara introduces 10,000 new designs every year and distributes 5.2 million clothing articles per week to a network of over 1925 stores in more than 86 countries. Their high product mix and vast global network makes demand forecasting for Zara a challenging endeavor. This thesis sets out to incorporate the effects from seasonality, product lifecycle, and cannibalization into a long term aggregate...
