background: injuries are the first leading but predictable, avoidable and preventable cause of death among under five-year children worldwide. the present study aimed to identify the factors associated with mothers' beliefs and practices concerning injury prevention in under five-year children . methods: this cross-sectional study was conducted from august to october 2011 in hamadan county, the...

Time-domain equalizers (TEQ) are used in the discrete multitone (DMT) transceivers in order to reduce the duration of the overall response of the transmission system, so that a shorter-length cyclic prefix could be used. The optimum TEQ is the one that results in maximum bit allocation to each block of DMT. However, the optimum design of TEQs turns out to be a very difficult task. In this paper...

High peak-to-average power ratio is a major problem that is inherent in all multicarrier communication systems. Clipping the high-peak power samples introduces (extra) clipping noise, which degrades the system performance in terms of bit-error rate (BER). Measuring BER usually requires a very long simulation time, as clipping occurs very rarely. In this letter, we propose a method called clippi...

Another Application for Trellis Shaping: PAR Reduction for DMT (OFDM) Werner Henkel, Member, IEEE, and Björn Wagner Abstract—A bound for the possible reduction of the peak-to-average ratio (PAR) dependent on the rate as well as possible practical procedures are presented. The idea of trellis shaping, originally used to minimize average transmit power in single-carrier systems, is applied to the...

This paper proposes a new blind adaptive channel shortening approach for multi-carrier systems. The performance of the discrete Fourier transform-DMT (DFT-DMT) system is investigated with the proposed DST-DMT system over the standard carrier serving area (CSA) loop1. Enhanced bit rates demonstrated and less complexity also involved by the simulation of the DST-DMT system.

Despite growing concerns regarding the increasing consumerism related to promotions, this research documents a positive effect of price promotions on consumers’ donation behavior. Specifically, authors propose that increase perceived resources, which in turn A series seven studies, combining field and experimental data, provide converging support for proposition its underlying mechanism resourc...

This study examines the relationship between cultural consumption pattern and an individual’s subjective well-being. We divide of activities by frequency, diversity, inclusion estimate monetary value participation in culture arts through marginal rate substitution. To reduce omitted variable bias, various factors are controlled for, such as basic demographics satisfaction with personal relation...

In recent decades, the declarations of “independent” central banks and the conduct of monetary policy have been assigned an ever increasing role in the pursuit of economic and financial stability. This is curious since there is, in practice, no body of scientific knowledge (evidence based beliefs) solid enough to have ensured agreement among central banks on the best way to conduct monetary pol...

OBJECTIVE All previous studies on monetary diet cost have examined the relationship of monetary cost of self-reported diet to self-reported, rather than biomarker-based, estimates of dietary intake. The present cross-sectional study examined the association between monetary costs of self-reported diet and biomarker-based estimates of nutrient intake. DESIGN Monetary diet cost (Japanese yen/10...
