The response of a steel structure is closely related to the behavior of its joints. This means that it is necessary to take explicit account of joint properties in order to ensure a consistent approach to design optimization of steel frames. Semi-rigid des ...
Critical sections in database storage engines impact performance and scalability more as the number of hardware contexts per chip continues to grow exponentially. With enough threads in the system, some critical section will eventually become a bottleneck. ...
Approximately 25 percent of the budget for the maintenance and renewal of railway tracks –in Switzerland more than a billion Swiss Francs– is used for the switches (points) and crossings (S&C). While in the mean time the budget expenditure for the maintena ...
This paper presents an efficient simplification method for regular meshes obtained with a binary subdivision scheme. Our mesh connectivity is constrained with a quadtree data structure. We propose a quadtree built especially for this class of meshes having ...
Recent studies have shown that the hardware behavior of database workloads is suboptimal when compared to scientific workloads, and have identified the processor and memory subsystem as the true performance bottlenecks, when running decision-support worklo ...
Analyzing the proliferation of item-level RFID, recent studies have identified the cost sharing of the technology as a gating issue. Various qualitative studies have predicted that conflict will arise, in particular in decentralized supply chains, from the ...
We present a consistent and transparent caching system for dynamic web pages produced by a server-side application using a back-end database. Cached pages always reflect current database values. No intervention from the programmer is necessary to implement ...
Approximately 25 percent of the budget for the maintenance and renewal of railway tracks is used for the switches (points) and crossings (S&C). While in the mean time the budget expenditure for the maintenance and renewal of plain track is optimized with e ...
We introduce a novel multi-resource allocator to dynamically allocate resources for database servers running on virtual storage. Multi-resource allocation involves proportioning the database and storage server caches, and the storage bandwidth between appl ...
