A fundamental question in development economics is the extent to which economic success is linked to basic features of human preferences. If people are extremely averse to financial risk, they may be reluctant to create businesses that may have inherently risky cash flows. If people are impatient, they may be reluctant to invest and educate their children.(More)
The National Academy of Engineering recently identified 14 grand challenges for engineering in the 21st century (www.engineeringchallenges. org). We believe that the continuing advances in ubiquitous sensing, processing, and computing provide the potential to tackle two of these 14 grand challenges: specifically, enhancing virtual reality and advancing(More)
In this article, we focus on the applicability of parallel computing architectures to video processing applications. We demonstrate different optimization strategies in detail using the 3-D convolution problem as an example, and show how they affect performance on both many-core CPUs and symmetric multiprocessor CPUs. Applying these strategies to case(More)
This paper proposes a new 3D propagation algorithm for the depth image-based rendering problem with multiple color and range cameras at arbitrary positions. The proposed algorithm efficiently renders novel images at arbitrary virtual views by propagating all available depth information from range cameras to color cameras, and then all available depth and(More)
We conducted field experiments to investigate how wealth, political history, occupation, and other demographic variables (from a comprehensive earlier household survey) are correlated with risk, time discounting and trust in Vietnam. Our experiments suggest risk and time preferences depend on the stage of economic development. In wealthier villages, people(More)
This paper proposes a new approach for depth image-based rendering (DIBR) with low resolution depth using the 3D propagation algorithm. Our novel depth edge enhancement method efficiently corrects and sharpens the depth edges in the propagated depth image using available high resolution color information. Experimental results show that only with 4% depth(More)
We conducted choice experiments in Vietnamese villages to investigate how wealth, political history, occupation, and other demographic variables (from a comprehensive earlier household survey) are correlated with risk, time discounting and trust measured in experiments. In villages with higher mean income, people are less loss-averse and more patient.(More)
The MITRE Corporation (MITRE) has been researching the Next Generation Air Transportation System (NextGen) avionics equipage incentives for a number of years, and through industry and government discussions, we have seen the perspectives of many National Airspace System (NAS) stakeholders. We believe that summary information on these perspectives should be(More)
