Diels-Alder chemistry has been used for the thermoreversible cross-linking of furan-functionalized ethylene/propylene (EPM) and ethylene/vinyl acetate (EVM) rubbers. Both furan-functionalized elastomers were successfully cross-linked with bismaleimide to yield products with a similar cross-link density. NMR relaxometry and SAXS measurements both show that the apolar EPM-g-furan precursor contai...

The error-in-variables-model (EVM) is the most statistically correct non-linear parameter estimation technique for reactivity ratio estimation. However, many polymer researchers are unaware of the advantages of EVM and therefore still choose to use rather erroneous or approximate methods. The procedure is straightforward but it is often avoided because it is seen as mathematically and computati...

A common figure of merit in multi-carrier systems is the error vector magnitude (EVM). A method for EVM computation of a multi-carrier signal without any underlying model (e.g., the Gaussianity assumption) was proposed in a previous work of the authors. However, it addressed only the case of identical constellations and power loadings in all tones. In practice, however, the constellation and po...

Traditional paper based voting procedure was very long and time-consuming process and very much prone to errors. Polling by Electronic Voting Machine (EVM) is a simple, safe and secure method that takes minimum of time. Current Electronic Voting Machine (EVMs) used in LOK SABHA and ASSEMBLY elections accepts only one vote from each voter. But in elections such as GRAMA PANCHAYATH and COOPERATIV...

In the recently developed Flexible Wireless System (FWS), the same platform needs to deal with different wireless systems. This increases nonlinear distortion in its wideband power amplifier (PA) because the PA needs to concurrently amplify multi-band signals. By taking higher harmonics as well as interand cross-modulation distortion into consideration, we have developed a method to analyticall...

Spectral precoding is a promising technique to suppress out-of-band emissions and comply with leakage constraints over adjacent frequency channels mask requirements on the unwanted emissions. However, spectral may distort original data vector, which formally expressed as error vector magnitude (EVM) between precoded vectors. Notably, EVM has deleterious impact performance of multiple-input mult...

OBJECTIVES Expectancy-Value Model (EVM) is the most structured model in psychology to predict attitudes by measuring attitudinal attributes (AAs) and relevant external variables. Because health value could be categorized as attitude, we aimed to apply EVM to explore its usefulness in explaining variances in health values and investigate underlying factors. METHODS Focus group discussion was c...
