Unstable Region in the Flat-Roof Resonator
Applied Optics, 1967Applicando il metodo numerico iterativo, già usato in un nostro precedente lavoro, abbiamo dimostrato che questo tipo di risonatore può avere regioni di instabilità dove sono presenti alte perdite. Applicando un metodo di perturbazioni successive, abbiamo dimostrato che esistono zone di inversione fra il modo fondamentale e il secondo modo pari.

Ventilation of Timber Flat Roofs
Batiment International, Building Research and Practice, 1985Reviewed here is a major co-operative investigation in Denmark into the effect of ventilation of timber flat (cold) roofs to combat condensation and moisture accumulation. Field measurements of moisture content in a number of test roofs over long periods and under different conditions are evaluated and conclusions drawn.

Structural Survey, 1988
This paper is predominantly concerned with flat roofs of timber construction with which the author is most familiar. The principles discussed are, however, generally applicable to roofs constructed of other materials.

Ponding of Liquids on Flat Roofs
Journal of the Structural Division, 1969Expressions are developed for the moments and deflections of simply-supported, prismatic beams subjected to various loading conditions simultaneous with ponding. These can be combined by a form of superposition to solve cases of combined loadings and different support conditions including continuous beams.

Applied Optics, 1965
A microwave or laser resonator with flat-roof mirrors is discussed from a theoretical point of view. When the angle of the roof is extremely small, on the order of 10−3 rad for microwaves or 10−3–10−6 rad for optics, this resonator has some features in common with the confocal resonator.

REPAIR AND MAINTENANCE OF FLAT ROOFS
Property Management, 1988The repair and maintenance of flat roofs probably creates one of the greatest headaches for a property manager as well as giving a touch of migraine to the professionals and advisers concerned with flat roofing problems. It was probably 15 years ago when we all became aware of the failings in design, construction and maintenance of flat roofs erected ...

Structural Survey, 1996
Points out that many problems have arisen in the flat roofing industry as a result of the inadequacy of the earlier specification. In addition the suggested remedies bring many other difficulties in their wake. Aims to identify the pitfalls and suggest some solutions.

A flat roof duct designed as a vent (L) or the like has a tubular lower part (2) with a supporting plate (6) associated to a countersupporting plate (12). For particular ease of utilisation, the tubular upper part (1) has a thread (8) below the countersupporting plate (12) carried by the tubular upper part (1) in order to join the latter to a central ...
