To lower hosting costs and service prices, database-as-a-service (DBaaS) providers strive to maximize cluster utilization without negatively affecting their users’ service experience. Some of the most effective approaches for increasing service efficiency result in the over-booking of the cluster with user databases. For instance, one approach is to reclaim cluster capacity from a database when...

Refurbishment and remanufacturing play a vital role in the sustainability of large industrial field, which aims at restoring equipment that is close to end their life. The EU-funded project RECLAIM proposes new approaches techniques support these two activities order achieve saving valuable materials resources by renewing recycling mechanical rather than scraping them when they exceed lifetime....

Some modern processors such as later Opterons R © and Power R © processors are able to support large pages sizes such as 1GiB and 16GiB. These page sizes are impractical to reserve at boot time because of the amount of memory that is potentially wasted. Currently, Linux R © as it stands is not well suited to support multiple page sizes because it makes no effort to satisfy allocations for conti...

PMOS is an incremental garbage collector designed specifically to reclaim space in a persistent object store. It is complete in that it will, after a finite number of invocations, reclaim all unreachable storage. PMOS imposes minimum constraints on the order of collection and offers techniques to reduce the I/O traffic induced by the collector. Here we present the first implementation of the PM...

Abstract Despite apparent political concern and action—often fuelled by high-profile cases campaigns—legislative institutional responses to image-based sexual abuse in the UK have been ad hoc, piecemeal inconsistent. In practice, victim-survivors are being consistently failed: law, police criminal justice system, traditional social media, website operators, their employers, universities schools...

Standard economic theory predicts that if property rights to pollute are clearly established, equilibrium outcomes in an effi cient emissions permit market will be independent of how the emissions permits are initially distributed. This so-called independence property has important implications for policy design and implementation. Past studies document a strong positive correlation between the...
