No full textThis article appeared in the 1931, November/December issue of "Handicrafter" magazine. It traces author "P.B."'s travels to various craft centers in the southern Appalachian mountains. Mentioned in the article are Allanstand Cottage Industries, The Spinning Wheel, Clementine Douglas, Winogene Redding, Evelyn Bishop, Mrs. Stone, Blue Ridge Weavers, Penland's Weaving Institute, Penland Weavers and Potters, Crossnore School, Mrs. H. N. Johnson, Pi Beta Phi Fraternity School, and Berea College's Fireside Industries. The author only gives a brief impression of his or her visit to each place. It is likely that author P.B. is Paul Bernat, editor of "Handicrafter" magazine

Experimental and computational study of the influence of pre-damage patterns in unreinforced masonry crack propagation due to induced, repeated earthquakes
No full textInduced seismicity in the north of the Netherlands has recently exposed unprepared, unreinforced masonry structures to considerable earthquake risk. While the ultimate-limit state capacity of the structures is vital to assess the individual’s risk, their behavior during more frequent, lighter earthquakes, leading to ‘lighter damage’, has shown to be strongly linked to economic losses and societal unrest. When observing the light damage caused by minor earthquakes, the existing state of the structure appears to be highly relevant for the final damage intensity and configuration: earthquakes that may have otherwise caused no apparent damage, may intensify existing damage. In particular, incipient damage due to settlements is common in the baked-clay and calcium-silicate brick masonry structures of the region.This paper details the study of full-scale laboratory walls, pre-damaged following typical (crack) patterns caused by settlements and tested with quasi-static lateral loads. The aggravation of the damage during a relevant number of load cycles is monitored using full-field digital image correlation. The damage is quantified objectively using a purposely-developed damage parameter.The tests are used (together with previous studies) to further calibrate computational finite element models, which coupled with detailed soil-structure interaction boundary conditions, are then employed to assess a larger number of structural geometries and pre-damaged configurations exposed to (repeated) induced earthquake acceleration histories.Both experimental and computational approaches show that settlement pre-damage in masonry structures increases the likelihood and the amount of further damage. This is more easily observed when some initial, yet limited damage exists and the masonry wall is exposed to moderate earthquake vibrations in the order of 30 millimeters per second.Accepted Author ManuscriptApplied Mechanic
A Critical Look At Mias
No full textIn this report the author brings a figure of the costs that go with the implementation of a landing aid, being a successor to the currently used system ILS. These cost figures should give the reader an insight in the possible costs necessary for the implementation of MIAS. Also a little discussion concerning the market value and the inherent political issues going with it are interwoven in part one of this thesis. Part two deals with the question of how other systems proved their required integrity norms. Especially a closer look at the way ILS System 4000 proved its maturity is given. Two possible methods to decide the service level of the equipment will be described and a list of works where several test specifications are described. Also, a new conception will be introduced, the “AI product”. Part three gives an answer to the following question: there is in the Kalman filter of MIAS the postulation of Gaussian shaped white noise, with a certain variance and on the other hand we want to fetch the stringent ICAO requirements (especially those for the system integrity). Do these two matters go hand in hand or do they conflict each other? Is there a way to fulfil the norms and in the meanwhile make use of the mathematical simplicity of Gaussian shaped white noise? As a reaction on these issues some approaches to adaptive Kalman filtering are described and a new manner of tuning a Kalman filter is set up, based on a system identification algorithm called MOESP.Applied SciencesElectrical EngineeringTelecommunications and Traffic Control Systems Grou
Het voorkomen van enkele niet-oorspronkelijk wilde grassoorten in Zeeland
No full textThe distribution of Digitaria ischaemum (Schreb.) Miihlenb., D. sanguinalis (L.)P.B., Echinochloa crus-galli (L.)P.B., Setaria glauca I (L.)P.B.and S. viridisi (L.)P.B. in the province of Zeeland is described and discussed. These species were mostly rare or absent in this region until 1950, but are now more or less common especially along some main roads where conditions seem to be optimal for these thermophylic plants.
Also the distribution of Eragrostis multicaulis Steud., E. poaeoides P.B., Panicum miliaceum I -, Setaria verticillata (L.) P.B. and Sorghum halepense (L.) Pers. is given and discussed. Some aspects of the ecology of E. poaeoides are added. The author proposes to insert S. halepense in the Standardlist of the Netherlands Flora 1985 as a naturalized species
Un désarroi créateur. À propos de Zastrozzi et de St Irvyne de P.B. Shelley
No full textCreative disarray : on Shelley y s Zastrozzi and St Irvyne
Shelley’s two early novels written at the age of nineteen, at a time of emotional turmoil, exemplify the creative function of a work of literature for the author : the work constructs the writer’s psyche. As he writes, he feels he is living. What writing does is uncover, unknown to the author, an unformed thought ; the inner sorrow registers and the outer turmoil appears post facto. Zastrozzi is a triumphant affirmation, a victory for the humiliated son who has been rejected by his father. St Irvyne, with its missing chapters and the poems erased by the characters of the novel stands for a deeper, more inexpressible form of anguish, a feeling of non-existence.Les deux romans de jeunesse de Shelley, Zastrozzi et St Irvine, écrits à dix-neuf ans, dans un moment de désarroi, sont exemplaires de la fonction créatrice de l’œuvre pour un auteur ; l’œuvre construit sa psyché. Écrivant, il se sent vivant. L’écriture met en effet au jour, à l’insu de l’auteur, un impensé ; le malaise intérieur s’inscrit et le drame intérieur se découvre après-coup. Zastrozzi est une affirmation triomphale, une victoire de l’«humilié offensé», rejeté par son père. St Irvyne, avec les chapitres manquants, les poèmes effacés par les personnages du roman, représente un malaise plus profond, indicible, le sentiment de ne pas exister.Berry Nicole.
