the accuracy of stereolithography (sl) product is very essential for meeting the intended functional applications. the parameters like layer thickness, hatch spacing, hatch overcure contribute significantly to the accuracy of the sl parts. in this paper an attempt has been made to identify the process parameters that influences on the accuracy of the parts made with ciba tool 5530 and optimize ...

In most countries general legislation on food (and feed) prohibits the sale of products containing poisonous or harmful substances, which would include relevant mycotoxins as well. So far only aflatoxin has been dealt with specifically in legislation. The aflatoxin control may include all foods (and feeds) but is limited in most countries to certain commodities likely to be heavily contaminated...

This paper proposes an efficient algorithm for optimum allocation of tolerances among components of an assembly with an objective to minimize the total cost of manufacturing while meeting the tolerance specifications of the assembly. The assembly is first represented as a two-layer constraint network by describing its functions, attributes and then entities. Forward propagation of entity tolera...

Making a product conform to the functional requirements indicated by the customer suppose to be able to manage the manufacturing process chosen to realise the parts. A simulation step is generally performed to verify that the expected generated deviations fit with these requirements. It is then necessary to assess the actual deviations of the process in progress. This is usually done by the ver...

The pain perception of 30 competitive swimmers was studied using experimentally induced ischaemic pain. The pain thresholds and tolerances of this group were compared with those of 30 club swimmers and 26 non-competitive athletes. While pain thresholds showed little difference between the groups, pain tolerances were considerably different. Pain tolerances of the competitive swimmers varied acc...

The purpose of this paper is to numerically investigate the fatigue life and crack growth path 2024 aluminum plate riveted joints. For purpose, according field observations, parameters affecting are obtained. Relevant geometric such as rivet shank length, hole diameter dimensional tolerances, well location pattern rivets material joints studied. In study, modeling performed calculate equivalent...

Dimensional tolerancing is a language used to communicate product quality specifications. Effective communication using this language relies on there being a common, shared meaning for tolerances. By this measure, the language of tolerances defined in modern standards does not support good communication. Some reasons for this are: the evolution of technology; the lack of research on tolerances ...

OBJECTIVE The objective of this mini-review is to examine a subset of literature that demonstrates multiple interactions between mechanics and biology within the spine and propose how incorporation of these mechano-biologic interactions can be applied to improve the conceptual understanding of tissue tolerances. BACKGROUND Low back pain represents a major musculoskeletal problem in the workpl...
