Benefit transfer is the use of pre-existing empirical estimates from one or more settings where research has been conducted previously to predict measures economic value related information for other settings. These transfers offer a feasible means provide on values when time, funding and constraints impede original valuation studies. The methods used applied benefit vary widely, however, it no...

Applications running on mobile terminals can benefit from exploiting transient connection opportunities: with an RTT of 2ms, even a 5s transient connection over a 50 Mbps 802.11a link represents 2500 RTTs and a chance to transfer up to 312.5 Mbytes. However, because of user mobility, such opportunistic time windows can be quite short. This paper investigates boosting CPU scheduling priorities o...

Shunt FACTS devices are used for controlling transmission voltage, power flow, reducing reactive losses, and damping of power system oscillations for high power transfer levels. In this paper the optimal location of a shunt FACT device is investigated for an actual line model of a transmission line having series compensation at the center. Effect of change in degree of series compensation on th...

We propose an architecture and several mechanisms for providing “Best Effort Differentiated Services” (BEDS), a set of services similar to Best Effort in that the QoS provided depends on the network conditions, but differentiated in their tradeoff between packet delay and packet loss probability. This proposal starts from the observation that a single Best Effort service does not fit the needs ...

Assisted Hatching (AH) is a technique performed after In Vitro Fertilization (IVF) and involves the artificial thinning or opening of the Zona Pellucida (ZP) prior to Embryo Transfer (ET) as an attempt to improve the probability of embryo implantation. AH can be performed by embryologists via mechanical, chemical, or laser-assisted means. A few studies suggest that a larger size of ZP opening/t...

OBJECTIVE To analyze the effectiveness of the Chilean System of Childhood Welfare in transferring benefits to socially vulnerable families. METHODS A cross-sectional study with a sample of 132 families from the Metropolitan Region, Chile, stratified according to degree of social vulnerability, between September 2011 and January 2012. Semi-structured interviews were conducted with mothers of the...

OBJECTIVE Individual meta-analyses were conducted for six training methods as part of a U.S. Army basic research project. The objective was to identify evidence-based guidelines for the effectiveness of each training method, under different moderating conditions, for cognitive skill transfer in adult learning. Results and implications for two of these training methods, learner control (LC) and ...

There is substantial evidence that driving skills improve during driver training, but the long-term safety benefit of such formal training remains unproven. Restricting the exposure of newly licensed drivers to more hazardous driving circumstances, as in graduated driver licensing (GDL) regimes, demonstrably reduces crash risk, but drivers remain at risk after the restrictions are eased. GDL an...

2D–2D hybrids have large heterointerfaces and strong interactions between the two components, leading to coupling effects that influence electronic structure of active sites benefit charge transfer during energy conversion reactions.
