Equations are everywhere! Between the atmosphere and the wing of a spaceship, in the blood flowing in an artery, on the demarcation line between ice and water at the poles, in the motion of the tides, in the charge density of a semiconductor, in the compression algorithms of a signal sending images from outer space. Such equations represent real problems. The Mathematical Engineer can see and u...

Medulloblastoma with extensive nodularity is a rare subtype of the most common malignant childhood brain tumor and has been associated with more favorable prognosis. The authors report the case of a 10-month-old girl with a posterior fossa tumor of excessive nodularity with decreased diffusivity on diffusion-weighted magnetic resonance imaging sequences and robust grape-like postgadolinium cont...

CHUM214 The Modern and the Postmodern In this course we will examine how the idea of "the modern" develops at the end of the 18th century and how being modern (or progressive, or hip) became one of the crucial criteria for understanding and evaluating cultural change during the last 200 years. Our readings will be drawn from a variety of areas-philosophy, novels, music, painting, and photograph...

We consider two mechanisms to procure differentiated goods: a request for quote and an English auction with bidding credits. In the request for quote, each seller submits a price and the inherent quality of his good. Then the buyer selects the seller who offers the greatest difference in quality and price. In the English auction with bidding credits, the buyer assigns a bidding credit to each s...

lending agricultural credits should follow a theoretical background. this research primarily investigated five theoretical patterns especially the islamic pattern about distribution of productive credits. then it examined the reliability of the patterns by accomplishing a case study about agricultural credits. the research was based on grounded theory approach. data were collected through obser...

Alternative measures of productive life (PL) were compared, and life expectancy factors were updated to replace estimates from 1993. Alternatives were proposed with extra credits for lactations longer than 10 mo and beyond 84 mo of age and for each calving so that an extremely long lactation would not receive more credits than multiple shorter lactations with dry periods between. Maximum credit...
