The concept of hypo-Euclidean norm for an n−tuple of vectors in inner product spaces is introduced. Its fundamental properties are established. Upper bounds via the BoasBellman [1]-[3] and Bombieri [2] type inequalities are provided. Applications for n−tuples of bounded linear operators defined on Hilbert spaces are also given.

This panel discusses the decline in the information systems field and argues that an emphasis on the major transformations enabled by technology will help rekindle interest and excitement about the technology. We will discuss a documentary on IT-enabled transformations that the Smith School at the University of Maryland is co-producing with Maryland Public Television for viewing on public telev...

Bike sharing systems consist of a fleet of bikes placed in a network of docking stations. These bikes can then be rented and returned to any of the docking stations after usage. Predicting unrealized bike demand at locations currently without bike stations is important for effectively designing and expanding bike sharing systems. We predict pairwise bike demand for New York City’s Citi Bike sys...

The present paper is a five-week content analysis of crime stories reported on television news. The sample consists of three nightly newscasts available on a rural, midwestern cable system. Included are nightly newscasts from a national network, a big city television station, and a small town channel. Findings from this exploratory study show that these three sources of television news differ s...

Axios River is one of the most important transboundary rivers between the Greek and the neighbour country FYROM in the Balkan area. In this paper, Artificial Neural Networks (ANNs) were used to derive and to develop models for prediction the monthly values of some water quality parameters of the river Axios at a station located at Axioupolis site of Greece near the Greece FYROM borders by using...

Release liners are part of a composite made of a label with its own adhesive on a release liner or carrier with its own release coating. The label comprises either a synthetic face stock such as polypropylene or paper. The adhesive is usually an organic material such as a polyacrylate or polyisoprene based rubber. The release liner can be made from various substrates treated with a suitable pro...

Many of today’s mechatronic systems – such as automobiles, automated factories or chemical plants – are a complex mixture of hardware components and embedded control software, showing both continuous (vehicle dynamics, robot motion) and discrete (software) behavior. The problems of estimating the internal discrete/continuous state and automatically devising control actions as intelligent reacti...

In this contribution, we investigate the idea of using cognitive radio to reuse locally unused spectrum to increase the total system capacity. We consider a multiband/wideband system in which users wish to communicate to the base station, subject to correlated scattering. We assume that each user knows only his channel and the unused spectrum through adequate sensing. Under this scheme, a cogni...

The access to water and the engineered landscapes accommodating its collection and allocation are pivotal issues for assessing sustainability. Recent mapping, sediment coring, and formal excavation at Tikal, Guatemala, have markedly expanded our understanding of ancient Maya water and land use. Among the landscape and engineering feats identified are the largest ancient dam identified in the Ma...
