Abstract

Multilayer aircore inductors fabricated in a range of interconnection technologies which are MCM compatible are presented and compared. These consist of thick‐film, low temperature cofired ceramic (LTCC), printed circuit board (PCB) and fine‐line plated copper on ceramic (copper plating). From a comparison of simulated and measured results, it can be concluded that a predictive design capability has been achieved for inductance and self‐resonant frequency (SRF). Modelling of AC resistance and Q requires further investigation.

Abstract

This paper will focus on the work which was carried out under the Brite‐EuRAM funded project, COMPRISE (BE 96‐3371), the objective of which was to develop new materials and manufacturing processes to embed passive components (resistors, inductors, capacitors) within printed wiring structures fabricated from laminate materials. For the realisation of integrated resistors, a commercially available planar resistor material is incorporated in different test structures. The technology consists of a copper foil of standard thickness on which a resistive layer is deposited by means of electroless plating. For the realisation of capacitors in multi‐layered PCB structures, significant progress was made in the development and fabrication of very thin laminates. Higher dielectric constants of these laminate materials enable the increase of the capacitance per unit area. For inductors, both aircore (no magnetic material) and magnetic core components have been investigated.

Abstract

Peduncluar hallucinosis is a rare neurological disorder characterized by visual hallucinations, often described to be vivid and dream-like. While the exact pathophysiology has yet to be elucidated, most cases to date have suggested an etiology stemming from lesions to the thalamus or midbrain. Here presented is a case of a 54-year-old female with peduncular hallucinosis secondary to a pontine cavernoma hemorrhage in the setting of essential hypertension. The patient's vivid visual and auditory hallucinations aligned temporally with the lesion's discovery and resolved after pharmaceutical treatment. This case represents a rare form of peduncular hallucinosis secondary to a pontine cavernoma hemorrhage leading to vasospasm in the arteries feeding the brainstem.

Abstract

Articulates the concept of market segmentation and examines, critically, how the main segmentation procedures lead to the conclusions that the main concern ought to be the classification of people in terms of usage of product and attitudes. Examines a new tool available to management (ACORN) a classification of residential neighbourhoods. States that in the UK 1983 General Election it emerged that nearly 40 per cent of the electorate did not vote for the party of their social class. Discusses segmentations in the electoral marketplace, which is preceded by a literature review. Concludes that the application of modern marketing techniques is ongoing in the electoral marketplace with regard to the UK. Finds that ACORN group findings of field research, undertaken to test claims, establishes that political attitudes changed regarding them during election campaigns.

Abstract

This design‐based seminar was aimed at broadening the horizons of designers and engineers. The greatest area of cost reduction in any electronics project is in making the right choices at the conception and design phases. This seminar was one step in this direction: a piece of 1·6 mm FR‐4 is not always the best substrate to use.

Abstract

Introduces MTV Networks Europe, where the author is Senior Vice‐President of Research and Planning, as Europe’s largest 24‐hour television network and an organisation which is constantly in touch with its vast Europe‐wide audience, including the youth market. Discusses youth culture and the youth market’s characteristics in an age of media explosion and disappearing national frontiers, where everything seems to comment on itself, context is everything, and individuality and authenticity are prized yet true originality is rare. Identifies the freedom that is on offer as essentially materialistic rather than political. Outlines the key influences on young people: the celebrity culture, music and fashion, technology and innovation, and family and friends. Points out that brand loyalty is weaker than in the past, and that branding tends to hide sameness rather than indicate difference. Describes the Collections of Cool research project at MTV, which analyses the youth market, and MTV’s “Switched On” publication covering microtrends in youth culture: this has identified likely hot artists and styles before they actually became successful. Lists some typical youth style trends: trucker caps, parachute pants, velour tracksuits, bling, school ties. Concludes with a look at the importance of music in youth culture and its links with fashion.
