Inhomogeneous coatings are promising for superior optical properties, e.g. broadband antireflection, in comparison to conventional HL-stack designs. Although a lot of excellent theoretical work on optical behaviour of rugates and gradient index films has been done during the last decades, there is no real breakthrough in industrial fabrication. The realization of such coatings leads to an exten...

Factorial experiments are widely used in industrial experimentation and other fields. Whenever a factorial experiment is not designed as a full factorial but as a – regular or non-regular – fraction thereof, choice between competing designs and interpretation of experimental results should take into consideration how the experimental plan will confound experimental effects. This article propose...

In this study, different designs of radial-flux direct-driven permanent magnet (PM) motors are compared. They should replace an induction motor and its gearbox for an industrial application requiring 5 kW and 50 rpm. The goal is to show if the use of concentrated windings brings some benefits for this application, the PM motors having a high number of poles. Different combinations of the number...

This paper discusses practical issues involved in applying logic built-in self-test (BIST) to four large industrial designs. These multi-clock designs, ranging in size from 200K to 800K gates, pose significant challenges to logic BIST methodology, flow, and tools. The paper presents the process of generating a BIST-compliant core along with the logic BIST controller for at-speed testing. Compar...

Compressor is the single largest consumer of primary energy (usually electricity) in an industrial refrigeration system and often become a focal point for energy efficiency improvement strategies. This is achieved either through the improvement of existing compressor designs, or by the introduction of new designs that is expected to overcome the drawbacks of existing compressors. This paper pre...

Complete randomization in many industrial and agricultural experiments is frequently impractical due to constraints in time, cost or existence of one or more hard-to-change factors. In these situations, restrictions on randomization lead to split-plot designs (SPD), allowing certain factor levels to be randomly applied to the whole plot units and remaining factor levels randomly to the subplot ...

In the last 10 years many designs and trial implementations of holonic manufacturing systems have been reported in the literature. Few of these have resulted in any industrial take up of the approach and part of this lack of adoption might be attributed to a shortage of evaluations of the resulting designs and implementations and their comparison with more conventional approaches. This paper pr...

Complex designs can only be understood, if the underlying information is provided in a concise way. In this context visualization is becoming an essential part of system design, understanding and debugging. In this paper we present an approach to visualization of designs described in SystemC. For the visualization an industrial tool including many features, like e.g. schematic viewing, cross-pr...

A class of Balanced Bipartite Row-Column Designs (BBPRC-designs) in two sets of treatments of sizes v1=v and v2=v+1 with replications 2(v-1) and 2v, respectively, has been constructed by replacing the ii-th positions of 2v × 2v standard cyclic latin square design in 2v treatments by 2v treatments by (2v+1)-th treatment. Such design finds applications in agricultural and industrial experimentati...

This paper describes a Hybrid DFT (H-DFT) architecture for low-cost, high quality structural testing in the high volume manufacturing (HVM) environment. This structure efficiently combines several testing and test data compression approaches to enable application of a huge amount of ATPG and Weighed Random-BIST (WR-BIST) patterns. Results obtained from the application of the H-DFT technique to ...
