Developments in sensor equipment and the Internet of Things increasingly allow production facilities to be monitored controlled remotely real-time. Organizations can exploit these opportunities reduce costs improve reliability by employing condition-based maintenance (CBM) policies. Another recently proposed option is adopt (CBP) policies that control deterioration dynamically adapting rate. Th...

the purpose of this study was to determine the seasonal changes of vital signs (body temperature, pulse rate and blood pressure) in relation to the working thermal conditions. in this study a total number of 202 permanent workers of bakeries were studied during summer and winter. the results showed the body temperature and pulse rate raised more in summer than in winter in all workers except wh...

the iranian civil code has limited the effects of unknown condition to nullification of such condition provided that it results in ignorance with respect to consideration. the code conveys no explicit provision concerning the effect of such condition not resulting in the ignorance. unknown condition refers to a condition on which there is not complete and comprehensive knowledge. this article l...

When first encountering data structures such as arrays, records and pointers programmers are often presented with pictorial representations. The use of pictures to describe data structures and their manipulation can help establish basic programming intuitions. The same is true of program proving where pictures are frequently used within the literature to describe program properties such as loop...

This paper presents a generalization of incremental condition estimation, a technique for tracking the extremal singular values of a triangular matrix. While the original approach allowed for the estimation of the largest or smallest singular value, the generalized scheme allows for the estimation of any number of extremal singular values. For example, we can derive estimates for the three smal...

In this dissertation, we explore the problem of fault detection and fault diagnosis for systems modeled as condition systems. A condition system is a Petri net based framework of components which interact with each other and the external environment through the use of condition signals. First, a system FAULT is defined as an observed behavior which does not correspond to any expected behavior, ...

Strong local minimizers with surfaces of gradient discontinuity appear in variational problems when the energy density function is not rank-one convex. In this paper we show that stability of such surfaces is related to stability outside the surface via a single jump relation that can be regarded as interchange stability condition. Although this relation appears in the setting of equilibrium el...
