Asynchronous stochastic systems are abundant in the real world. Examples include queuing
systems, telephone exchanges, and computer networks. Yet, little attention has been given …

Matching three moments with minimal acyclic phase type distributions

A Bobbio, A Horváth, M Telek - Stochastic models, 2005 - Taylor & Francis
A number of approximate analysis techniques are based on matching moments of
continuous time phase type (PH) distributions. This paper presents an explicit method to …

Closed form solutions for map** general distributions to quasi-minimal PH distributions

T Osogami, M Harchol-Balter - Performance Evaluation, 2006 - Elsevier
Approximating general distributions by phase-type (PH) distributions is a popular technique
in stochastic analysis, since the Markovian property of PH distributions often allows …

Efficient duration and hierarchical modeling for human activity recognition

T Duong, D Phung, H Bui, S Venkatesh - Artificial intelligence, 2009 - Elsevier
A challenge in building pervasive and smart spaces is to learn and recognize human
activities of daily living (ADLs). In this paper, we address this problem and argue that in …

A new cumulative shock model with damage and inter-arrival time dependency

SH Ranjkesh, AZ Hamadani, S Mahmoodi - Reliability Engineering & …, 2019 - Elsevier
In this paper, a system is considered that fails when the cumulative damage due to shocks
exceeds the handling capacity of the system. It is also supposed that if the time between two …

Multi-server queueing systems with multiple priority classes

M Harchol-Balter, T Osogami, A Scheller-Wolf… - Queueing Systems, 2005 - Springer
We present the first near-exact analysis of an M/PH/k queue with m> 2 preemptive-resume
priority classes. Our analysis introduces a new technique, which we refer to as Recursive …
