The COP400 single-chip controller family members provide computational ability and speed which is more than adequate to intelligently manage power control. These controllers provide digital control while low cost and short turnaround enhance COPSTM desirability. The COPS controllers are capable of 4 ms cycle times which can provide more than adequate computational ability when controlling 60 Hz...

We consider a variant of the game of Cops and Robbers, called Lazy Cops and Robbers, where at most one cop can move in any round. We investigate the analogue of the cop number for this game, which we call the lazy cop number. Lazy Cops and Robbers was recently introduced by Offner and Ojakian, who provided asymptotic upper and lower bounds on the lazy cop number of the hypercube. By coupling th...

Introduction The second International Workshop on Collaborative Peer-to-Peer Information Systems, COPS06 was held in Manchester University as part of WETICE-2006. It was the second meeting devoted to the study of the emerging field of Cooperative Information Systems and P2P networks or Cooperative P2Pbased Information Systems (COPS). The first edition has been focused on trust management and mi...

One way of providing technological support for CoPs is to help participants to produce, structure and share information. As this information becomes more and more multimedia in nature, the challenge is to build multimedia authoring and publishing tools that meets CoPs requirements. In this paper we analyze these requirements and propose a multimedia authoring model and a generic platform on whi...

We give an algorithmic characterisation of finite cop-win digraphs. The case of k > 1 cops and k l 1 robbers is then reduced to the one cop case. Similar characterisations are also possible in many situations where the movements of the cops and/or the robbers are somehow restricted. © 2006 Elsevier B.V. All rights reserved.

OBJECTIVES Cut-off points (COPs) for appendicular lean mass (ALM) index, essential to define low muscle mass (LMM) in the elderly, have never been officially defined for Poland. The aim of the study was to establish them. Additionally, the significance of body mass index (BMI) for correctly defining the COPs in a young, healthy reference group was assessed. METHODS The study was composed of r...

Purpose – This paper seeks to scope the nature and form of practices, understandings and institutional arrangements thatmight contribute to the successful ‘‘design’’ and continuity of Communities of Practice (CoP) in a state government department in Australia. The study aims to provide research evidence to support the design and establishment of a CoP based on systems thinking within this depar...

Testosterone deficiency has been correlated with increased cardiovascular diseases, which in turn has been associated with increased oxidative stress. Several studies have considered cholesterol oxidation products (COPs) as oxidative stress biomarkers, since some of them play pro-oxidant and pro-inflammatory roles. We have previously described the cardioprotective effects of a dosahexaenoic aci...
