Basic avionics module design for general aviation aircraft

The design of an advanced digital avionics system (basic avionics module) for general aviation aircraft operated with a single pilot under IFR conditions is described. The microprocessor based system provided all avionic functions, including flight management, navigation, and lateral flight control. The mode selection was interactive with the pilot. The system used a navigation map data base to provide operation in the current and planned air traffic control environment. The system design included software design listings for some of the required modules. The distributed microcomputer uses the IEEE 488 bus for interconnecting the microcomputer and sensors

A Method of Developing Analytical Multipartite Delocalization Measures for Mixed W-like States

We present a method of developing analytical measures of $k$-partite delocalization in arbitrary $n$-body W-like states, otherwise known as mixed states in the single excitation subspace. These measures calculate the distance of a state to its closest reference state with $k-1$ entanglement. We find that the reference state is determined by the purity of the state undergoing measurement. Measures with up to 6-body delocalization for a 6-body system are derived in full, while an algorithm for general $k$-partite measures is given.Comment: 8 pages, 3 figure

Helminths in the hygiene hypothesis:Sooner or later?

There is increasing recognition that exposures to infectious agents evoke fundamental effects on the development and behaviour of the immune system. Moreover, where infections (especially parasitic infections) have declined, immune responses appear to be increasingly prone to hyperactivity. For example, epidemiological studies of parasite-endemic areas indicate that prenatal or early-life experience of infections can imprint an individual's immunological reactivity. However, the ability of helminths to dampen pathology in established inflammatory diseases implies that they can have therapeutic effects even if the immune system has developed in a low-infection setting. With recent investigations of how parasites are able to modulate host immune pathology at the level of individual parasite molecules and host cell populations, we are now able to dissect the nature of the host–parasite interaction at both the initiation and recall phases of the immune response. Thus the question remains – is the influence of parasites on immunity one that acts primarily in early life, and at initiation of the immune response, or in adulthood and when recall responses occur? In short, parasite immunosuppression – sooner or later

One Bold Experiment

A monthly exchange of letters from 165 seventh graders in an arts school in Charleston, South Carolina to similar classrooms in 16 countries around the world proved to be the writing project that captured every state writing standard all at once -- brainstorming, writing, collaboration, analysis, proofreading, and re-writing. This one activity was the highlight of the year for each student as letters and gifts poured in from every continent September to June. This was truly a teacher\u27s dream come true

STOL aircraft transient ground effects. Part 1: Fundamental analytical study

The first phases of a fundamental analytical study of STOL ground effects were presented. Ground effects were studied in two dimensions to establish the importance of nonlinear effects, to examine transient aspects of ascent and descent near the ground, and to study the modelling of the jet impingement on the ground. Powered lift system effects were treated using the jet-flap analogy. The status of a three-dimensional jet-wing ground effect method was presented. It was shown, for two-dimensional unblown airfoils, that the transient effects are small and are primarily due to airfoil/freestream/ground orientation rather than to unsteady effects. The three-dimensional study showed phenomena similar to the two-dimensional results. For unblown wings, the wing/freestream/ground orientation effects were shown to be of the same order of magnitude as for unblown airfoils. This may be used to study the nonplanar, nonlinear, jet-wing ground effect

Psychopathology as a Function of Unconscious Conflict and Neuroticism with Support for the Projective Hypotheses

A report submitted to the Faculty Research Committee by Larry D. Smyth in 1977 on psychopathology as a function of unconscious conflict and neuroticism with support for the projective hypotheses

Maintaining market principles: Government auditors, PPP equity sales and hegemony

The UK’s government auditors, the National Audit Office (NAO), play a central role in the accountability relations surrounding government expenditure. Commonly portrayed as being independent, they carry out performance audits assessing value for money. To date, the emerging market for PPP equity transactions has attracted little attention. This paper explores that emerging market through a Gramscian framework utilising the concepts of ‘common sense’ and ‘good sense’, focusing on a dialogical analysis of a NAO report on the topic. In the process, the paper contributes to the debate about the nature and role of government auditors
