Hide It Or Unbundle It: A Comparison Of The Antitrust Investigations Against Microsoft In The U.S. And The E.U., Sue Ann Mota

The University of New Hampshire Law Review

[Excerpt] "Microsoft Corporation, the world’s largest software company, has been facing antitrust scrutiny globally. In the U.S., after what’s been called the antitrust trial of the century, a consent decree was reached between Microsoft, the United States government, and several states, that closely resembled the litigated remedy that the remaining states received. Only Massachusetts appealed the litigated remedy, which was approved by the appeals court on June 30, 2004. In the United States, Microsoft was required to hide, but not remove, the Internet Explorer browser on the Windows Operating System. While antitrust litigation was ongoing in the United States against …

Adaptive Blind Multiuser Detection Over Flat Fast Fading Channels Using Particle Filtering, Yufei Huang, Jianqiu Zhang, Isabel Tienda Luna, Petar M. Djuric, Diego Pablo Ruiz Padillo

Electrical & Computer Engineering

We propose a method for blind multiuser detection (MUD) in synchronous systems over flat and fast Rayleigh fading channels. We adopt an autoregressive-moving-average (ARMA) process to model the temporal correlation of the channels. Based on the ARMA process, we propose a novel time-observation state-space model (TOSSM) that describes the dynamics of the addressed multiuser system. The TOSSM allows an MUD with natural blending of low-complexity particle filtering (PF) and mixture Kalman filtering (for channel estimation). We further propose to use a more efficient PF algorithm known as the stochastic -algorithm (SMA), which, although having lower complexity than the generic PF …

An Estimate Of The Gas Transfer Rate From Oceanic Bubbles Derived From Multibeam Sonar Observations Of A Ship Wake, Thomas C. Weber, Anthony P. Lyons, David L. Bradley

Center for Coastal and Ocean Mapping

Measurements of gas transfer rates from bubbles have been made in the laboratory, but these are difficult to extrapolate to oceanic bubbles where populations of surfactants and particulate matter that inhibit gas transfer are different. Measurements at sea are complicated by unknown bubble creation rates that make it difficult to uniquely identify and observe the evolution of individual bubble clouds. One method that eliminates these difficulties is to measure bubbles in a ship wake where bubble creation at any given location is confined to the duration of the passing ship. This method assumes that the mechanisms slowing the gas dissolution …

Protocols For Calibrating Multibeam Sonar, Kenneth G. Foote, Dezhang Chu, Terence R. Hammer, Kenneth Baldwin, Larry A. Mayer, Lawrence C. Hufnagle Jr., J Michael Jech

Center for Coastal and Ocean Mapping

Development of protocols for calibrating multibeam sonar by means of the standard-target method is documented. Particular systems used in the development work included three that provide the water-column signals, namely the SIMRAD SM2000/90- and 200-kHz sonars and RESON SeaBat 8101 sonar, with operating frequency of 240 kHz. Two facilities were instrumented specifically for the work: a sea well at the Woods Hole Oceanographic Institution and a large, indoor freshwater tank at the University of New Hampshire. Methods for measuring the transfer characteristics of each sonar, with transducers attached, are described and illustrated with measurement results. The principal results, however, are …

Exploring Causal Influences, Eric M. Neufeld, Sonje K. Kristtorn, Qingjuan Guan, Manon Sanscartier, Colin Ware

Center for Coastal and Ocean Mapping

Recent data mining techniques exploit patterns of statistical independence in multivariate data to make conjectures about cause/effect relationships. These relationships can be used to construct causal graphs, which are sometimes represented by weighted node-link diagrams, with nodes representing variables and combinations of weighted links and/or nodes showing the strength of causal relationships. We present an interactive visualization for causal graphs (ICGs), inspired in part by the Influence Explorer. The key principles of this visualization are as follows: Variables are represented with vertical bars attached to nodes in a graph. Direct manipulation of variables is achieved by sliding a variable value …

This paper describes an inquiry based instructional planning model that reflects lessons from the literature on effective teaching for diverse classrooms. An example of a high school lesson exemplifies the model. The model includes a framework for planning supports for students with extraordinary learning challenges.

Next Edition Of Iho S-57 (Edition 4): Much More Than Encs, Lee Alexander, Michael Brown, Barrie Greenslade

Center for Coastal and Ocean Mapping

The primary goal for the next edition of S-57 (Edition 4) is to support a greater variety of hydrographic-related digital data sources, products, and customers. This includes matrix and raster data, 3-D and time-varying data (x, y, z, and time), and new applications that go beyond the scope of traditional hydrography (e.g., high-density bathymetry, seafloor classification, marine GIS). It will also enable the use of web-based services for data discovery, browsing, query, analysis, and transfer. S-57 Edition 4.0 will not be an incremental revision of Edition 3.1. Edition 4 will be a new standard that includes both additional content and …

Indicators Of Climate Change In The Northeast 2005, Adam Markham, Cameron P. Wake

The Sustainability Institute Publications

Climate changes. It always has and always will. What is unique in modern times is that human activities are now a significant factor causing climate to change. This is evident in the recent rise in key greenhouse gases, such as carbon dioxide (CO2), in the atmosphere, and in the recent increase in global temperatures in the lower atmosphere and in the surface ocean.

The evidence presented in this report clearly illustrates that climate in New England is also changing. Over the past 100 years, and especially the last 30 years, all of the climate change indicators for the region reveal …

The Design Of An Uncertainty Model For The Tidal Constituent And Residual Interpolation (Tcari) Method For Tidal Correction Of Bathymetric Data, Rick Brennan, Kurt Hess, Lloyd C. Huff, Steve Gill

Center for Coastal and Ocean Mapping

Recent advances in processing multibeam sonar data brought about by the Combined Uncertainty and Bathymetric Estimator (CUBE) [1] have demonstrated the value of identifying and tracking survey uncertainties. Most of these uncertainties were outlined in Hare, Godin, and Mayer uncertainty model developed in 1995 [2]. That report identified the uncertainties in the various electronic systems used to acquire the bathymetric data. However, one of the largest contributors to the overall error budge t in a near coastal hydrographic survey is that contributed by water level uncertainty. As the ocean mapping industry pushes for ever finer spatial details in its data, …

Coral Reef Electronic Chart Initiative, Protecting Corals, Saving Ships, Lee Alexander, Kathryn L. Ries

Center for Coastal and Ocean Mapping

The Office of Coast Survey, NOAA is conducting a pilot project in the Florida Keys National Marine Sanctuary to convert existing coral, marine protected areas (MPA) and other marine GIS information into a format suitable for use with shipboard Electronic Chart Display and Information Systems (ECDIS). Specifically, existing data will be converted into Marine Information Objects (MIOs) conforming to IHO S-57 data standards that become a supplemental information layer to be used with Electronic Navigational Charts (ENC) in ECDIS. The project goal is to strengthen marine resource conservation by bringing critical coral, MPA, and other environmental protection-related information to the …

Empirical Analysis Of Aerial Camera Filters For Shoreline Mapping, Christopher Parrish, Maryellen Sault, Stephen A. White, Jon Sellars

Center for Coastal and Ocean Mapping

Accurate, up-to-date national shoreline is critical in defining the territorial limits of the Unites States, updating nautical charts, and managing coastal resources. The National Oceanic and Atmospheric Administration (NOAA) delineates the interpreted shoreline photogrammetrically using tide-coordinated stereo photography acquired with black-and-white infrared emulsion. In this paper, we present the results of a two-phased study aimed at quantifying the effect of camera filter selection on the interpreted shoreline when utilizing this method of shoreline mapping.

Geocoder: An Efficient Backscatter Map Constructor, Luciano E. Fonseca, Brian R. Calder

Center for Coastal and Ocean Mapping

The acoustic backscatter acquired by multibeam and sidescan sonars carries important information about the seafloor morphology and physical properties, providing valuable data to aid the difficult task of seafloor characterization, and important auxiliary information for a bathymetric survey. One necessary step towards this characterization is the assemblage of more consistent and more accurate mosaics of acoustic backscatter. For that, it is necessary to radiometrically correct the backscatter intensities registered by these sonars, to geometrically correct and position each acoustic sample in a projection coordinate system and to interpolate properly the intensity values into a final backscatter map. Geocoder is a …

Investigation Of Bottom Fishing Impacts On Benthic Structure Using Multibeam Sonar, Sidescan And Video, Mashkoor A. Malik, Larry A. Mayer

Center for Coastal and Ocean Mapping

Bottom fishing gear is known to alter benthic structure, however changes in the shape of the sea floor are often too subtle to be detected by acoustic remote sensing. Nonetheless, long linear features were observed during a recent high-resolution multibeam sonar survey of Jeffreys Ledge, a prominent fishing ground in Gulf of Maine, located about 50 km from Portsmouth, NH. These marks, which have a relief of only few centimeters, are presumed to be caused by bottom dredging gear used in the area for scallop and clam fisheries. The extraction of these small features from a noisy data set (including …

Multi-Dimensional, Multi-National, Multi-Faceted Hydrographic Training: The Nippon Foundation Gebco Training Program At The University Of New Hampshire, Dave Monahan, Clive Angwenyi, Hugo Montoro, Taisei Morishita, Abubakar Mustapha, Walter Reynoso Peralta, Shereen Sharma, Srinivas Karlapati

Center for Coastal and Ocean Mapping

Hydrographic training entered a new era when students arrived at the University of New Hampshire in August of 2004 to form the first class of the Nippon Foundation GEBCO (General Bathymetric Chart of the Oceans) training program. Born out of the need to replenish GEBCO’s aging human material, and of the desire to spread deep ocean mapping capabilities more widely throughout the world, the program attracted applications from 57 students in over thirty countries. The seven selected each had post graduate training and several years experience, but differed in that three were hydrographers, two geologists and two oceanographers. Classes planned …

Panoramic Images For Situational Awareness In A 3d Chart-Of-The-Future Display, Matthew D. Plumlee, Colin Ware, Roland J. Arsenault, Rick Brennan

Center for Coastal and Ocean Mapping

Many early charts featured sketches of the coastline, providing a good picture of what the shore looked like from the bridge of a ship. These helped the mariner to distinguish one port from another during an approach and establish their rough position within that approach. More recent experimental 3D chart interfaces have incorporated 3D models of land topography and man-made structures to perform the same function. However, topography is typically captured from the air, by means of stereophotogrammetry or lidar and fails to present a good representation of what is seen from a vessel’s bridge. We have been conducting an …

Probabilistic Modeling Of One Dimensional Water Movement And Leaching From Highway Embankments Containing Secondary Materials, Defne S. Apul, Kevin H. Gardner, T. Taylor Eighmy, Ernst Linder, Tara Frizzell, Ruth Roberson

Civil & Environmental Engineering

Predictive methods for contaminant release from virgin and secondary road construction materials are important for evaluating potential long-term soil and groundwater contamination from highways. The objective of this research was to describe the field hydrology in a highway embankment and to investigate leaching under unsaturated conditions by use of a contaminant fate and transport model. The HYDRUS2D code was used to solve the Richards equation and the advection–dispersion equation with retardation. Water flow in a Minnesota highway embankment was successfully modeled in one dimension for several rain events after Bayesian calibration of the hydraulic parameters against water content data at …
