This paper investigates serial crowdfunders' performance over successive campaigns. Adopting an expected utility maximization framework in a setting with asymmetric information about hidden entrepreneurial actions and types, we propose that crowdfunding amounts raised will follow cyclical pattern A sample drawn from the population of crowdfunders on Kickstarter confirms this prediction suggests...

The performance of 2D digital imaging systems depends on several factors related with both optical and electronic processing. These concepts have originated standards, which have been conceived for photographic equipment and bi-dimensional scanning systems, and which have been aimed at estimating different parameters such as resolution, noise or dynamic range. Conversely, no standard test proto...

This work represents the first step toward a DDDAS for Wildland Fire Prediction where our main efforts are oriented to take advantage of the computing power provided by High Performance Computing systems to, on the one hand, propose computational data driven steering strategies to overcome input data uncertainty and, on the other hand, to reduce the execution time of the whole prediction proces...

Nuclear research with radioactive beams is the most recent challenge for both fundamental nuclear physics [1] and particles accelerators technologies research. Beam diagnostics is a typical component of any accelerators based facility, but for radioactive beams the technology to be used presents many analogies with that one used for standard nuclear detectors. The main reason of this peculiarit...

Moving range queries over mobile objects are important in many location management applications. There have been quite a few research works in this area. However, all existing solutions assume an open space environment, which are either not applicable to spatial network environment or require nontrivial extensions. In this paper, we consider a new class of query called Dynamic Range Query. A dy...

This paper deals with the problem of optimizing two-stage structure decision making units (DMUs) where the activity and the performance of two-stage DMU in one period effect on its efficiency in the next period. To evaluate such systems the effect of activities in one period on ones in the next term must be considered. To do so, we propose a dynamic DEA approach to measure the performance of su...
