This paper considers preferences over risky timed outcomes and proposes the weighted temporal utility (WTU) model which separates anticipated subjective evaluations of outcomes from attitudes toward psychological distance induced by risks and delays. Anticipating the subjective evaluation of an outcome requires the decision maker to project himself to the future and to imagine how much he will ...

In this paper we study the economic and performance evaluation of two non identical unit cold standby systems with hardware failure and human error. After pre specific time known as Maximum operation time (MOT) the system undergoes for PM from operative state. The failure and repair rate times follow exponential distribution. There is a single server who visits the system immediately whenever n...

This paper proposes a context-aware information delivery system (CAIDS) using a UMTS Release 5 architecture and a wireless LAN. We present the concept and the system architecture of CAIDS, discuss the disposition of functional modules using the network-centric approach and clarify the CAIDS can provide the users with context-aware information delivery services including context-aware personal c...

Because of its wide applicability many e cient implementations of the Fast Fourier Transform have been developed We propose that an e cient implemen tation can be produced automatically and reliably by partial evaluation Partial evaluation of an unoptimized implementation produces a speedup of over times The automatically generated result of partial evaluation has performance com parable to or ...

Providing network bandwidth guarantees over an Ethernet requires coordination of the network nodes for traac prioritization such that real-time data can have deterministic access to the network. We have shown previously how RETHER, a software-only token passing protocol can eeciently provide real-time support over a single shared Ethernet segment. This work extends the token passing mechanism i...
