We obtain a robust, non-parametric, estimate of the Hub-ble constant from galaxy linear diameters calibrated using HST Cepheid distances. Our method is independent of the parametric form of the diameter function and the spatial distribution of galaxies and is insensitive to Malmquist bias. We include information on the galaxy rotation velocities ; unlike Tully-Fisher, however, we retain a fully...

This paper proposes a study of the effects of knowledge management systems (KMS) on individual and organizational performance. The study seeks to answer the following question: Which factors determine the impact of KMS on performance by individuals and groups? A model for KMS and performance is developed. This model takes the special characteristics of KMS into account, and extends the theory o...

In order to solve domain equations over 1-bounded compact metric spaces, xed points of functors on categories of 1-bounded compact metric spaces are studied. Two categories of 1-bounded compact metric spaces are considered: KMS and KMS E. In both categories, objects are isomorphic if and only if they are isometric. As a consequence, provided that the operation of a domain equation can be extend...

in this study, we used teleseismic data which was recorded by 5 stations (dhr, ghg, kom, lin and vis) of the kermanshah seismic network from 2003 to 2007 with mb?5.5 and epicentral distances from 30° to 95°. the crustal structure beneath these stations was determined by the modeling of the p receiver functions. the main phases, which were observed in our final p receiver functions, are moho con...

NuCypher KMS is a decentralized Key Management System (KMS) that addresses the limitations of using consensus networks to securely store and manipulate private, encrypted data [1]. It provides encryption and cryptographic access control, performed by a decentralized network, leveraging proxy re-encryption [2]. Unlike centralized KMS as a service solutions, it doesn’t require trusting a service ...

Knowledge management (KM) and knowledge management systems (KMS) have been paid much attention by both researchers and practitioners. Yet little is known about the enabling factors in organizational KMS adoption. In this paper, we first review the technology adoption literature at individual and organizational levels to investigate the factors of adoption in a general sense. Then, we specifical...

As part of our program to map the large-scale distribution of galaxies behind the Milky Way, we used the Parkes 210 ft (64m) radio telescope for pointed H I observations of a sample of low surface-brightness (due to heavy obscuration) spiral galaxies selected from the deep optical Zone of Avoidance (ZOA) galaxy catalog in the Hydra/Antlia region (Kraan-Korteweg 2000a). Searching a simultaneous ...
