Research made over the past decade shows the use of increasingly complex methods and heavy platforms to achieve autonomous flight in cluttered environments. However, efficient behaviors can be found in nature where limited sensing is used, such as in insec ...
This paper presents an efficient adaptive combination strategy for the distributed estimation problem over diffusion networks in order to improve robustness against the spatial variation of signal and noise statistics over the network. The concept of minim ...
This paper presents an efficient modelling technique for partially reflective surface (PRS) antennas, based on the substitution of the actual detailed PRS by an uniform equivalent surface impedance. The properties of the equivalent surface are rigorously e ...
In the standard real options approach to investment under uncertainty, agents formulate optimal policies under the assumptions of risk neutrality or complete financial markets. Although these assumptions are crucial to the implications of the approach, the ...
Nowadays, the amount of multimedia contents is explosively increasing and it is often a challenging problem to find a con- tent that will be appealing or matches users’ current mood or affective state. In order to achieve this goal, an efficient indexing t ...
This paper considers a single source transmitting data to one or more receivers/users over a shared wireless channel. Due to random fading, the wireless channel conditions vary with time and from user to user. Each user has a buffer to store received packe ...
This article shows that portfolio constraints can give rise to rational asset pricing bubbles in equilibrium even if there are unconstrained agents in the economy who can benefit from the induced limited arbitrage opportunities. Furthermore, it is shown th ...
This paper provides a unifying approach for valuing contingent claims on a portfolio of credits, such as collateralized debt obligations (CDOs). We introduce the defaultable (T, x)-bonds, which pay one if the aggregated loss process in the underlying pool ...
In this study I look at how inter-organizational ties with reputable venture capital (VC) firms affect the valuations that entrepreneurial ventures receive from public investors at initial public offerings (IPOs). I propose that the effect of signaling is ...
This paper studies the impact of ambiguity and ambiguity aversion on equilibrium asset prices and portfolio holdings in competitive financial markets. It argues that attitudes toward ambiguity are heterogeneous across the population, just as attitudes towa ...
