Title of Thesis : System Performance Criteria in CDMA Networks Using Gold codes Yong H. Kim, M. S. E. E., 1988 Thesis directed by : Dr. Joseph Frank Associate Professor Department of Electrical Engineering First, we have presented the autocorrelation and crosscorrelation properties for periodic and aperiodic binary sequences. The generation of binary sequences using shift registers with feedbac...

Such mawkish passages recur with numbing frequency through this record of eighteen months in the life of an American, white, middle class, midwest girl who is fifteen when the book begins. Her father is the unnamed Dean of an unnamed American University; they live in a lovely Spanish style house with walls of thick dark wood and two steps down into a sunken living room. One can imagine. Her mot...

OBJECTIVE Observational research suggests that placing graphic images on cigarette warning labels can reduce smoking rates, but field studies lack experimental control. Our primary objective was to determine the psychological processes set in motion by naturalistic exposure to graphic vs. text-only warnings in a randomized clinical trial involving exposure to modified cigarette packs over a 4-w...

Fostered by and embedded in the general development of information and communications technology (ICT), the evolution of tsunami warning systems (TWS) shows a significant development from seismic-centred to multisensor system architectures using additional sensors (e.g. tide gauges and buoys) for the detection of tsunami waves in the ocean. Currently, the beginning implementation of regional ts...

BACKGROUND Pictorial health warning labels on cigarette packaging have been proposed for the U.S., but their potential influences among populations that suffer tobacco-related health disparities are unknown. PURPOSE To evaluate pictorial health warning labels, including moderation of their influences by health literacy and race. METHODS From July 2011 to January 2012, field experiments were...

This study, concerned with the development of driver interface criteria for a rear obstacle detection system, assessed the appropriateness of alternative warning timing algorithms and evaluated various interface approaches for presenting warning information to drivers. Interface testing used a minivan and a passenger sedan equipped with a prototype rear obstacle detection system. Two different ...

BACKGROUND In France, since 2007, there is a compulsory warning recommending abstinence during pregnancy on every container of alcohol. Awareness of this warning, which consists of a small pictogram, is unknown. The aim of this study was to assess awareness of the warning and risk perceptions about prenatal drinking in pregnant and postpartum women. METHODS A cross-sectional survey was carrie...

BACKGROUND Alcohol warning labels have a limited effect on drinking behavior, potentially because people devote minimal attention to them. We report findings from two studies in which we measured the extent to which alcohol consumers attend to warning labels on alcohol packaging, and aimed to identify if increased attention to warning labels is associated with motivation to change drinking beha...

The reduced noise of electric and hybrid electric vehicles has been of particular concern because of the potential danger that these vehicles pose to pedestrians when their approach is inaudible against background noise. To address this issue, the use of additional warning sounds in such vehicles is being considered in various countries. The aim of this study was to examine the feasible level o...

This introductory paper explores how the use of information affects the effectiveness of early warning systems. By effectiveness, we refer to the capacity of the system to detect and decide on the existence of a threat. There are two aspects to effectiveness: being able to see the evidence that is indicative of a threat; and making the decision, based on the weight of the evidence, to warn that...
