The upside of downtime: An interpretative phenomenological analysis on recovery experience during discretionary time in men’s professional tennis tour
Recovery, defined as the restoration process of physiological and psychological resources for functional readiness, is associated with individual’s motivation and performance at workplace, and well-being (Demerouti, Bakker, Geurts, & Taris, 2009; Sonnentag, 2001; Sonnentag & Natter, 2004). Despite …

QUANTIFYING THE COST OF DATA CENTER COOLING APPROACHES INCLUDING SERVICE-LEVEL AGREEMENTS
… overlook the financial penalties associated with downtime defined in Service-Level Agreements (SLAs). This research addresses this gap by creating a model that integrates capital and operational costs with a stochastic discrete-event simulator for maintenance, failures, repairs, and availability. …

Resilire: Achieving High Availability Through Virtual Machine Live Migration
… present a technique for reducing VM migration downtimes called FGBI. FGBI reduces the dirty memory updates that must be migrated during each migration epoch by tracking memory at block granularity. Additionally, it determines memory blocks with identical content and shares them to reduce the …

A first step towards zero down time: the creation of synergy through equipment acquisition within the constraints of a small budget in an Army with civilian oversight - a case of the Botswana Defense Force (BDF)
… null hypothesis, Ho, for this thesis is that: Downtime or turnaround time (TAT) cannot be reduced by favorable independent variables. This follows from the preliminary conclusion that there is substantial downtime as at present. It postulates that something can be done to ameliorate past …

Elastically Housed Kinematic Couplings for InterchangeableElectric Vehicle Batteries
… technologies has lagged due to immense charging downtime, but kinematic couplings have the potential to bridge this barrier by allowing for battery swaps and simultaneous operation and back-up battery charging. Designing parameters such as an elastic housing to damp the battery’s connection could …

The benefits of structured training on manufacturing process ramp-up : a process based cost model approach
… on two production metrics, unplanned equipment downtime and reject rate, a series of analyses are presented. A framework for conducting analyses is developed using Process Based Cost Modeling. This framework is applied to various automobile part manufacturing processes. The results indicate that …

Failure Finding Interval Optimization for Periodically Inspected Repairable Systems
… research in this area considers non-negligible downtime due to repair/replacement but ignores the downtime caused by inspections. In many situations, however, inspection time is non-negligible. We address this gap by proposing an optimal failure finding interval (FFI) considering both …
