High Degree Vertices, Eigenvalues and Diameter of Random Apollonian Networks
ABSTRACT. Upon the discovery of power laws [8, 16, 30], a large body of work in complex network analysis has focused on developing generative models of graphs which mimick real-wor...

Perturbation analysis of an M/M/1 queue in a diffusion random environment
Abstract. We study in this paper an M/M/1 queue whose server rate depends upon the state of an independent Ornstein-Uhlenbeck diffusion process (X(t)) so that its value at time t i...

Time Capsule Signature: Efficient and Provably Secure Constructions
Time Capsule Signature, first formalized by Dodis and Yum in Financial Cryptography 2005, is a digital signature scheme which allows a signature to bear a (future) time t so that t...

Persistent Authenticated Dictionaries and Their Applications
Abstract. We introduce the notion of persistent authenticated dictionaries, that is, dictionaries where the user can make queries of the type “was element e in set S at time t?...

Worst Case Reliability Prediction Based on a Prior Estimate of Residual Defects
In this paper we extend an earlier worst case bound reliability theory to derive a worst case reliability function R(t), which gives the worst case probability of surviving a furt...

Time Capsule Signature
Abstract. We introduce a new cryptographic problem called time capsule signature. Time capsule signature is a ‘future signature’ that becomes valid from a specific future time...

Parallelizing time with polynomial circuits
We study the problem of asymptotically reducing the runtime of serial computations with circuits of polynomial size. We give an algorithmic size-depth tradeoff for parallelizing ...

The Midlifekicker Microarchitecture Evaluation Metric
We introduce the midlifekicker metric for evaluating microarchitectures mostly during the design process. We assume a microarchitecture designed at a time T-1 and estimate if a ne...

Finding time-dependent shortest paths over large graphs
The spatial and temporal databases have been studied widely and intensively over years. In this paper, we study how to answer queries of finding the best departure time that minim...
