Introduction of an information feedback loop to enhance the urban transportation modeling system

The Urban Transportation Modeling System (UTMS) is a methodology used to estimate urban travel demand. This demand is measured as the volume of traffic that flows through a system of streets and highways. Through the use of traffic assignment software, parts of UTMS have become automated. One of the newest automated processes is the extraction of a subarea from a larger model. This extraction process is important to the local planner because it maintains a linkage from the regional model to the local model and it allows the user to extract an already distributed trip table rather than building one from scratch. This subarea process as practiced, is a one way information flow. The larger model is calibrated and its information is then passed down to the subarea model. The author proposes that an information feedback loop should be inserted into the process. This information channel is created by the subarea modeler using his calibration information and extra data collected specifically for the subarea model. This information is looped back to the regional model where it is used in recalibrating the larger model. The results of the test case in this thesis are used to develop general conclusions regarding the applicability of the feedback process, as well as areas of future improvement and research

Economical Litigation Agreements: The Civil Litigation Prenup Need, Basis, and Enforceability

This article identifies the basis and limits of the parties\u27 abilities to define and enforce discovery in an ex ante contract. Despite the deficiencies of litigation, the free, public dispute resolution forum of the civil justice system provides significant value in commercial disputes. That value can be used to maximum mutual advantage only if parties replace the infinite discovery permitted in conventional litigation with the finite discovery contracted in Economical Litigation Agreement (ELA) litigation. This article will help parties to understand the benefit and enforceability of the ELA

A review of the factors involved in older people's decision making with regard to influenza vaccination: a literature review

Aims and objectives. The aim of this paper was to develop an understanding of the factors involved in older people's decision making with regard to influenza vaccination to inform strategies to improve vaccine uptake and reduce morbidity and mortality. Background. Influenza is a major cause of morbidity and mortality world-wide. In the UK, it accounts for 3000–6000 deaths annually; 85% of these deaths are people aged 65 and over. Despite this, and the widespread and costly annual government campaigns, some older people at risk of influenza and the associated complications remain reluctant to take advantage of the offer of vaccination. Methods. A review of the English language literature referring to older people published between 1996 and 2005 was the method used. Inclusion and exclusion criteria were identified and applied. Results. The majority of the literature was quantitative in nature, investigating personal characteristics thought to be predictors of uptake, such as age, sex, co-morbidity, educational level, income and area of residence. However, there was little discussion of the possible reasons for the significance of these factors and conflict between findings was often evident, particularly between studies employing different methodologies. Other factors identified were prior experience, concerns about the vaccine, perceived risk and advice and information. Relevance to clinical practice. The wealth of demographic information available will be useful at a strategic level in targeting groups identified as being unlikely to accept vaccination. However, the promotion of person-centred ways of working that value the health beliefs, attitudes, perceptions and subjective experiences of older people is likely to be more successful during individual encounters designed to promote acceptance. Without more research in investigating these concepts, our understanding is inevitably limited

Surface Flaw Detection with Ferromagnetic Resonance Probes

Eddy current methods of flaw detection have been in use for many years. Frequencies used in this type of flaw detector normally range from tens of kilohertz to a few megahertz. We report on recent progress using a resonant probe which operates in the gigahertz frequency range, and compare its performance with classical eddy current methods

Surface Flaw Detection with Ferromagnetic Resonance Probes

Ferromagnetic probes resonating at microwave frequencies have previously been shown to function as sensitive detectors of surface breaking flaws in metals. A swept frequency mode of operation was used, with the resonance line of the probe displayed on an oscilloscope and the presence of a flaw indicated by a shift of the resonance line. This type of presentation lacks good discrimination between lift-off and and flaw signals and also reduces the probe scanning speed because the entire resonance line must be swept at each measurement point on the test specimen. Our new system operates under cw conditions, with a network analyser type of display giving the probe input impedance in polar coordinates. This provides liftoff discrimination and also enhances sensitivity. Experimental curves and their theoretical interpretations will be presented, and a portable prototype instrument will be described
