A survey on approximation algorithms for scheduling with machine unavailability
- In Algorithmics of Large and Complex Networks: Design, Analysis, and Simulation
, 2009
"... Abstract. In this chapter we present recent contributions in the field of sequential job scheduling on network machines which work in parallel; these are subject to temporary unavailability. This unavailability can be either unforeseeable (online models) or known a priori (offline models). For the o ..."

Query Caching and Optimization in Distributed Mediator Systems
- In Proc. of ACM SIGMOD Conf. on Management of Data
, 1996
"... Query processing and optimization in mediator systems that access distributed non-proprietary sources pose many novel problems. Cost-based query optimization is hard because the mediator does not have access to source statistics information and furthermore it may not be easy to model the source&apos ..."

's performance. At the same time, querying remote sources may be very expensive because of high connection overhead, long computation time, financial charges, and temporary unavailability. We propose a costbased optimization technique that caches statistics of actual calls to the sources and consequently
Unraveling BitTorrent’s File Unavailability: Measurements and Analysis
"... BitTorrent suffers from one fundamental problem: the long-term availability of content. This occurs on a massivescale with 38 % of torrents becoming unavailable within the first month. In this paper we explore this problem by performing two large-scale measurement studies including 46K torrents and ..."

The impact of stock-outs on whether, how much and what to buy
, 2000
"... This paper investigates the impact of stockouts on category purchase incidence, purchase quantity and within-category choice, in different consumer segments. Based on scanner data for two product categories, we find that stockouts may lead to the purchase of smaller quantities, and to asymmetric (no ..."

(non-IIA) choice shifts. Reactions to stockouts are also found to be linked to the shopper’s basket size, 3 Stock-outs, or temporary unavailability of items on the retailers ’ shelves, are a non-negligible phenomenon at retail. Recent studies report not only a high incidence of stock-outs for FMCG in a
Redundancy Management for P2P Storage
"... P2P storage systems must protect data against temporary unavailability and the effects of churn in order to become platforms for safe storage. This paper evaluates and compares redundancy techniques for P2P storage according to availability, accessibility, and maintainability using traces and theore ..."

Fault-Tolerant 3D Localization for Outdoor Vehicles
- in IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS
, 2006
"... Abstract — This paper presents a robust kalman-based localization for outdoor vehicles. Outdoor vehicles require a faulttolerant system that can manage temporary unavailable sensor measurements. The sensor system of the vehicle consists of odometry, inertial measurement unit (IMU) and differential g ..."

A reputationbased announcement scheme for VANETs
- IEEE Transactions on Vehicular Technology
"... Abstract—Vehicular ad hoc networks (VANETs) allow vehicles to generate and broadcast messages to inform nearby vehicles about road conditions, such as traffic congestion and accidents. Neighboring vehicles can utilize this information, which may improve road safety and traffic efficiency. However, m ..."

, messages generated by vehicles may not be reliable. We propose a novel announcement scheme for VANETs based on a reputation system that allows evaluation of message reliability. We present a secure and efficient scheme that is robust and fault tolerant against temporary unavailability of the central server
Malaysian multinational companies (MNC): Permanent and temporary nature of tax planning
, 2016
"... Abstract: Tax gap measures differences between tax theoretically due and tax actually paid. Researchers and authority attribute tax gap as a measure of tax planning. At a firm level, the measure is often referred to book-tax difference (BTD), which has been utilised by researchers as a measure of t ..."

An approach to adaptive distributed execution monitoring for workflows in service-based systems
- Proc. 31st Annual Int’l Computer Software and Application Conf
"... Systems based on Service-Oriented Architecture are called service-based systems (SBS), and comprise of computing services offered by various organizations. Users of SBS often require these services to be composed into complex workflows to perform their high-level tasks. The users usually have certai ..."
