This paper describes IBIS, a distributed file system for a network. of UNIX machines. IBIS provides two levels of abstraction: file access transparency and file location transparency. File access transparency means that all files are accessed in the same way, regardless of whether they are remote or local. File location transparency hides the location of files in the network. IBIS provides a si...

We examine the welfare implications of two types of central-bank transparency: the publication of the information underlying the central bank’s decision (decision transparency) and the release of the information that the central bank observes afterwards (postdecision transparency). Decision transparency does not make the public better informed in equilibrium. Even so, it may be socially desirab...

This paper provides a short survey on transparency tools for privacy purposes. It defines the term transparency tools, argues why they are important and gives examples for transparency tools. A classification of transparency tools is suggested and some example tools are analyzed with the help of the classification.

Supplier value networks are an emerging inter-organizational form resulting from efforts to integrate across fragmented supply chains, for the purpose of efficiency and performance gains. By proposing value network transparency as a central construct in supplier value networks, this paper identifies the different dimensions of transparency and presents a theoretical framework for achieving valu...

phytoplanktons are the first bio- indicators of pollution in aquatic ecosystems. phytoplankton assemblage and aquatic ecosystems are always influenced by environmental factors therefore these environmental changes and threats must be understood in any ecosystem. phytoplankton are inexpensive and readily available bio- indicators. in the present study, phytoplankton were used to study the sefid ...

EIT waveforms have components synchronous with cardiac activity, which are often assumed to originate from the blood perfusion. There are numerous other contributions to this signal. The goal of this paper is to provide a list of the factors which could be at the origin of these cardiacrelated components, to help guide future research.

In this paper, a new frequency-based approach to motion segmentation is presented. The proposed technique represents the sequence as a spatio-temporal volume, where a moving object corresponds to a three-dimensional object. In order to detect the “3D volumes” corresponding to significant motions, a new scheme based on a band-pass filtering with a set of logGabor spatio-temporal filters is used....

The effect a perturbing field has on an electromagnetically induced transparency within a three-level system is presented. The perturbing field is applied resonant between one of the lower levels of the system and a fourth level. The electromagnetically induced transparency feature is split and this is measured experimentally for both single and bichromatic driving fields. In the single-driving...

In bilateral teleoperation, the operator holds a local robot which determines the motion of a remote robot and continuously receives delayed force feedback. Transparency is a measure of teleoperation system fidelity. The ideal teleoperator system is the identity channel, in which there is neither delay nor distortion. During the last decades transparency was widely analyzed using two-port hybri...
