A orthogonal decomposition of a general wideband space-time multipath channel is derived assuming antenna arrays at both the transmitter and receiver. Knowledge of channel state information at the transmitter is used to decompose the channel. This decomposition serves as a framework for eeciently managing the degrees of freedom in the space-time channel to trade-oo diversity and throughput. Sig...

We examine the effects of digital access on the prevalence of democracy and its diffusion via geographical and trade networks across 152 countries between 2000 and 2008. Although civil liberties and media freedom show a consistently positive relationship with different forms of digital access, our dynamic models that allow co-evolution of digital access, democracy and trade tie formation sugges...

In an environment of increasing importance of South–South bilateral trade partnerships, we assess the potential for improving bilateral trade between India and five Central Asian countries in this paper, and construct a trade potential index. We find huge untapped potential for increasing trade, and that India and Central Asia would benefit from policies that encourage trade, including bilatera...

We demonstrate that the phase of randomized complex-valued projections of real-valued signals preserves information about the angle, i.e., the correlation, between those signals. This information can be exploited to design quantized angle-preserving embeddings, which represent such correlations using a finite bit-rate. The proposed embeddings generalize known results on binary embeddings and 1-...

Randomized controlled trials test new drugs using various debiasing devices to prevent participantsfrom manipulating the trials. But participants often dislike controls, arguing that they impose apaternalist constraint on their legitimate preferences. The 21st Century Cures Act, passed by USCongress in 2016, encourages Food and Drug Administration use alternative testing methods,incorporating p...

present study, compares iran's agricultural products competitiveness power with mena's countries during 1995-2011. for accomplishing mentioned goal, first, agricultural commodities export and import indices calculated for each one of twenty countries of mentioned region and then revealed comparative advantages index of agricultural commodities trade calculated. results showed that iran had comp...

In previous lectures, we discussed the design of state feedback controllers using using eigenvalue (pole) placement algorithms. For single input systems, given a set of desired eigenvalues, the feedback gain to achieve this is unique (as long as the system is controllable). For multi-input systems, the feedback gain is not unique, so there is additional design freedom. How does one utilize this...

I report estimates for a fixed-effects model of country-level Gini coefficients as a function of economic freedom along with relevant control variables. Gini coefficients are drawn from the UNU/WIDER World Income Inequality Database Version 2.0a, while economic freedom is measured by the Fraser Institute’s Economic Freedom of the World index. Controls are included for per capita income, politic...

The main purpose of this study is to detect the mediation effect logistic performance index in relationship between enabling trade and volume foreign trade. simple model was created by using published World Economic Forum, logistics Bank, data countries. used 94 countries’ for years 2016, 2014, 2012, compiled 282 samples total. In application part study, correlation coefficients variables were ...
