Software transactional memory provides an appealing alternative to locks by improving programmability, reliability, and scalability without relying on custom hardware. However, existing STMs are impractical because they add high overhead and provide weak semantics—or they provide strong atomicity semantics and add even higher overhead. Existing STMs are impractical largely due to the cost of co...

The context of delays significantly affects delay responsibility. Among other things, recoverable damages for a delay should be related to the timing of the corresponding delay and its effect on indirect costs. This paper presents an alternative and integrated approach for quantifying and apportioning delay responsibility. It considers the context of a delay in terms of its timing and the degre...

The article carries out a critical analysis of the traditional approach to costing. paper reveals problem distortion cost manufactured products from point view making management decisions. authors justify expediency using ABC system for accounting and distribution overhead costs. study gives interpretation concepts used in functional highlights discloses step-by-step algorithm indirect costs wh...

There are two major paradigms for linear-space heuristic search: iterative deepening (IDA*) and recursive best-first search (RBFS). While the node regeneration overhead of IDA* is easily characterized in terms of the heuristic branching factor, the overhead of RBFS depends on how widely the promising nodes are separated in the search tree, and is harder to anticipate. In this paper, we present ...

AIM The purpose was to assess the direct costs of screening for high blood pressure and blood glucose in dental care and of follow-up in primary health care and, based on these data, arrive at a prediction function. Study population. All subjects coming for routine check-ups at three dental health clinics were invited to have blood pressure or blood glucose measurements; 1,623 agreed to partici...

Swizzling is a mechanism used by OODBMSs to convert pointers from their disk formats to a more eecient in-memory format. In this project we analyze the the costs associated with swizzling in Texas, an OODBMS which does pointer swizzling at page-fault time. We report the costs of signal handling, object translation, the virtual memory overhead, and unswizzling. We compare the performance of Texa...

Data cubes provide aggregate information to support the analysis of the contents of data warehouses and databases. An important tool to analyze data in data cubes is the range query. For range queries that summarize large regions of massive data cubes, computing the query result on-they can result in non-interactive response times. To speed up range queries, values that summarize regions of the...
