Santander does not speculate on the reason for these patterns of student membership; in a useful introduction to the dictionary, she describes the form and purpose of the registers she has used, and fills in background details of the medical curriculum and the organization of the faculty. But despite its very real achievements, a historian may well regret that Escolares medicos never goes beyon...
[1] The TIMED Doppler Interferometer (TIDI) on the NASA Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) satellite has been measuring horizontal winds in the mesosphere and lower thermosphere (MLT) since 2002. Because of the high inclination of the TIMED orbit, TIDI measures the horizontal winds from pole to pole every orbit. This paper presents the first assessment of the spa...
Fault tolerant methods using dynamically reconfigurable devices have been studied to overcome wear-out failures. However, quantitative comparisons have not been sufficiently assessed on device lifetime enhancement with these methods, whereas they have mainly been evaluated individually from various viewpoints such as additional hardware overheads, performance, and downtime for fault recovery. T...
Studies of angular and time distributions and CP-violating observables in Bs → J/ψφ decays yield a space of parameters which can be considerably reduced if relative strong phases among different amplitudes are specified. We show that the relations between Bs → J/ψφ and B → J/ψK amplitudes given by flavor symmetry [actually U(3) rather than SU(3)] are likely to be quite reliable, and hence the u...
Cloud manufacturing as a trend of future manufacturing would provide cost-effective, flexible and scalable solutions to companies by sharing manufacturing resources as services with lower support and maintenance costs. Targeting the Cloud manufacturing, the objective of this research is to develop an Internetand Web-based service-oriented system for machine availability monitoring and process p...
This paper presents a genetic algorithm for a scheduling problem frequent in printed circuit board manufacturing: a hybrid flowshop with unrelated machines, sequence dependent setup time and machine availability constraints. The proposed genetic algorithm is a modified version of previously proposed genetic algorithms for the same problem. Experimental results show the advantages of using new c...
During the back-end manufacturing process of IC, intervention of spot defects induces extra and missing material of interconnects causing circuit failures. In this paper, a new type of spot defects called interconnect “narrowing defect” is defined. Interconnect narrowing occurs when spot defects induce missing material of interconnects without resulting in a complete cut. The narrow sites of de...
The iterative process an+1 = (an + 3bn)/4, bn+1 = ( +bn )/2 is studied in detail. The limit of this quadratically converging process is explicitly identified, as are the uniformizing parameters. The role of symbolic computation, in discovering these nontrivial identifications, is highlighted.
The 2 out of 4-system (2oo4) is an advanced safety architecture. A 2oo4-system is 2-failure safe, this means that at least two of the four channels have to work correctly in order to trigger the safety function. In order to classify the quality of a system different parameters have to be calculated, like the PFD and MTTF. In this paper, equations are indicated for PFD for normal and common-caus...
The precise design of a system may be considered a trade secret which should be protected, whilst at the same time component manufacturers are sometimes reluctant to release full test data (perhaps only providing mean time to failure data). In this situation it seems impractical to both produce an accurate reliability assessment and satisfy all parties’ privacy requirements. However, we present...
