Abstract The satellite uses an electric propulsion system (EPS) to complete the north-south station-keeping (NSSK) work. Due change of centroid position during whole life period, thrust pointing adjustment is required minimize deviation between vector and centroid, avoid additional interference torque decrease protection efficiency EPS. In this paper, method designed, mathematical model angle e...

Books are my greatest weakness and collecting them and other printed material is something I have done all of my life. I still spend several hours a week wandering around in bookshops, and the reason I’m late for appointments in Cambridge is that I have a flat above a bookseller with a large stock of remaindered and second-hand books. My passion for the printed word began soon after I learnt to...

Consider a sports competition in which participants alternately perform a scored task (such as the distance a discus is thrown), and a list of the top m scores is updated throughout. We consider the average number and distribution of records among the top m throughout and at the end of the competition. We also answer questions concerning the number of times the list changes, when each change oc...

With the increasing demand of energy and limitation bottom-fixed wind turbines in moderate deep waters, floating offshore are doomed to be right technical choice they bound enter a new era rapid development. The mooring system is vital turbine for station-keeping under harsh environmental conditions. In terms existing projects, this paper devoted discussing current status systems equipment. Thi...

The prevailing labor market models assume that minimum wages do not affect the labor supply schedule. We challenge this view in this paper by showing experimentally that minimum wages have significant and lasting effects on subjects’ reservation wages. The temporary introduction of a minimum wage leads to a rise in subjects’ reservation wages which persists even after the minimum wage has been ...

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...

We address the problem of maximizing privacy stochastic dynamical systems whose state information is released through quantized sensor data. In particular, we consider setting where about system obtained using noisy measurements. This data and transmitted to a (possibly untrustworthy) remote station public/unsecured communication network. aim at keeping (part of) private; however, because netwo...
