In today's fiercely competitive products market, product warranty has started playing an important role. The warranty period offered by the manufacturer/dealer has been progressively increasing since the beginning of the 20th Century. Currently, a large number of products are being sold with long-term warranty policies in the form of extended warranty, warranty for used products, service contra...

The SPIN extension presented in this article is meant as a way to facilitate the modeling and verification of object-oriented programs. It provides means for the formal representation of some run-time mechanisms intensively used in OO software, such as dynamic object creation and deletion, virtual function calls, etc. This article presents a number of language extensions along with their implem...

OBJECTIVE The purpose of this article is to report on the opening plenary session of the Association of Chiropractic Colleges Educational Conference-Research Agenda Conference (ACC-RAC) 2014, "Aiming for Effective Change: Leadership in Chiropractic Education, Research and Clinical Practice." DISCUSSION Speakers with extensive backgrounds with implementing substantial change on a broad level s...

WSN are ad-hoc mobile networks in which sensors have limited resources and communication capabilities. These reasons poses lots of technical challenges on sensor deployment scheme because it affect the cost and detection capability. The objective of this paper is to deploy sensors (indoor environment) in sensing field to ensure both sensing coverage and network connectivity with a minimum cover...

We develop how a notion of e ective scale can be introduced in a formal way. For continuous signals a scaling argument directly gives that a natural unit for measuring scale-space lifetime is in terms of the logarithm of the ordinary scale parameter. That approach is, however, not appropriate for discrete signals, since then an in nite lifetime would be assigned to structures existing in the or...

This paper reports the first measurement of the effective B0 s → J/ψK0 S lifetime and an updated measurement of its time-integrated branching fraction. Both measurements are performed with a data sample, corresponding to an integrated luminosity of 1.0 fb−1 of pp collisions, recorded by the LHCb experiment in 2011 at a centre-of-mass energy of 7 TeV. The results are: τ eff J/ψK0 S = 1.75 ± 0.12...
