We prove two theorems which extend known results concerning periodic orbits and topological entropy in one-dimensional dynamics. One of these results concerns the adding machine map (also called the odometer map) fα defined on the α-adic adding machine ∆α. We let H(fα) denote the greatest lower bound of the topological entropies of F , taken over all continuous maps F of the interval which cont...

We show that given a type α of an adding machine, for a dense set of parameters s in the interval [ √ 2, 2], if f is the tent map with slope s, then the restriction of f to the closure of the orbit of the turning point is topologically conjugate to the adding machine map of type α.

Due to the massive deployment of the internet and intranet-based services there is a need to consolidate management data generated by heterogeneous sources and to provide an end-to-end service & business level view of IT resources. Because of this the need for a standard enterprise management framework is more acute than ever before. There are currently two major internet-based proposals which ...

In the study of legislatures, little attention is given to the second chambers of bicameral parliaments. We know something about some second chambers, most notably the US Senate, but relatively little is known about second chambers as a particular species of institution. To some extent, this is attributable to their perceived subordinate status. They are second chambers. In bicameral systems, r...

Test oracles are programs which check the output of test cases run on other programs. We describe techniques which add value to formally-defined test oracles in three ways: (a) by measuring functional coverage of test suites, (b) by giving automated support to the process of validating the oracles, and (c) by automating the generation of test cases from the oracles. The techniques involve the u...

Metrology has a stigma of being non-productive and in many cases the aim of production engineers is to reduce metrology costs to an absolute minimum. This paper analyzes the role of metrology in production and demonstrates, how metrology can generate value. It illustrates different ways to evaluate the benefit of metrology and gives metrologists guidance to sell metrology with economic argument...

Reflective testing is a procedure in which the laboratory specialist adds additional tests and/or comments to an original request, after inspection (reflection) of the results. It can be considered as an extension of the authorization process where laboratory tests are inspected before reporting to the physician. The laboratory specialist will inevitably find inconclusive results, and additiona...
