A 0.5 Vrms, 12 W wirelessly powered patch type fabric sensor is presented for wearable body sensor network to continuously monitor personal bioelectric signals. Thick film electrodes are screen printed on the fabric with various metal components and their impedances of ~100k are characterized. A 2-stage nested chopped analog readout front end (AFE) is optimized for the fabric sensor with reduce...

We define a security model for FPGAs that provides virtualization and sharing of the reconfigurable fabric. The approach is to encapsulate the reconfigurable fabric within the context of a standard OS process, separated from the security-sensitive resources iff the process is a user-mode one. The key elements of the model are the software application loader and the physical interface between th...

Heat and mass transfer in a permeable fabric system used for Personal Protective Equipment (PPE) was investigated using hot air jet impingement conditions to mimic the jet exhaust of Short Take-Off and Vertical Landing (STOVL) aircraft. The STOVL aircraft uses a thrust-vectoring nozzle of the jet engine and a lift fan in order to vertically land and take off a short runaway. The jet engine exha...

factor  is introduced for direct head loss calculation and sizing in dual-diameter laterals of sprinkler and trickle irrigation systems when the hazen-williams equation is to be applied. application of this factor prevents trial and error and uses fewer head-loss equations in calculating the total friction loss and designing dual-diameter laterals. the proposed factor is a function of total num...

Rehabiliating Bushehr historic fabric and paying to it as an important urban fabric through increasing capabilities and facilities is main concern. Bushehr historical fabric can be the consequence of several factors the most important of which is the Persian Gulf and its past history as a national one. This fabric, is organic, dense, compact, having its own characteristics. One of its main prio...

This paper considers the problem of interconnect wire delay in digital integrated circuits. The correct wire sizing and buffer insertion/sizing can reduce the interconnect delay. The interconnect wire is divided into segments and to optionally buffers are inserted between two adjacent segments. But it is important to select appropriate values for the size of buffers as well as the lengths and w...

there are instances in which it is desirable to determine relationships among fruit physical attributes. for example, fruits are often graded on the basis of size and projected area, but it may be more suitable and/or economical to develop a machine which grades by mass. therefore, a relationship between mass and dimensions or projected areas and/ or volume of fruits is needed. various grad...

The present study describes the development and initial validation of a new obesity-specific, self-report measure of health-related quality of life (HRQOL) for children aged 5-13 years. Participants included 141 obese children (mean age=9.2 years, 67% female, 55% black, mean zBMI=2.52) and their primary caregivers. Children completed Sizing Me Up (obesity-specific HRQOL) and the PedsQL (generic...

An environmentally friendly and inexpensive substitute to the widely used poly(vinyl alcohol) (PVA) has been developed from soy proteins for textile warp sizing. Textile processing is the major source of industrial water pollution across the world, and sizing and desizing operations account for nearly 30 % of the water consumed in a textile plant. PVA is one of the most common sizing agents use...

A variety of Software Sizing approaches have been conjectured in the literature. While many of these approaches have been used for Software Cost Estimation, none were specifically designed for Software Costing. This paper reviews current methods of Software Sizing to determine their suitability for Software Cost Estimation. The approach differs from previous approaches in that it is based on a ...
