TALAT Lecture 3203: The Filling of Castings
This lecture describes the function and design of all parts of the running and gating systems used in the production of castings. The students will be able to tackle the design of a simple running system in a systematic manner. Basic knowledge of foundry processes and basic mathematics is assumed.
Applications of Vector Operators for Surface Atmospheric/Oceanic Processes
Vector operations are crucial for the understanding of many processes affecting surface conditions in the atmosphere and the oceans. Gradients, dot and cross products, and the Laplacian of surface variables (e.g., pressure, temperature, moisture, salinity, wind and ocean currents to name a few) are concepts that create considerable angst for students in meteorology and physical oceanography classes. The purpose of this activity is to teach vector concepts within the context of the atmospheric an
International Classification of Function, Disability and Health
This package was originally designed for undergraduates in Medicine at the University of Nottingham. It will also be useful to students in nursing, allied health professions and pharmacy. Practitioners in these fields, who are new to the ICF, will also find it a useful introduction. It describes the International Classification of Functioning, Disability and Health (ICF), a classification system published by the World Health Organisation to describe health status. This system is widely used in r
Ashes of Roses Evening Dress
'Ashes of Roses' synthetic chiffon dress, long batwing sleeves, deep cuffs fastened with five self-covered buttons. Bodice and skirt lined, sleeves unlined. Bodice is blouson style, skirt is full and cut in panels. Lining has long zip fastener, bodice back is secured with four self-covered buttons (slightly larger than those on cuffs). Neck is bound in chiffon, hem is overlocked. - from the The Betty Smithers Design Collection at Staffordshire University.
Delamination cracks in h-BN particles.
h-BN particles were subjected to compressive stress in the (0001) planes (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and react with Si3N4 to form BN. Su
Dissolved Oxygen and Biochemical Oxygen Demand
This EPA website provides general information about dissolved oxygen, including what it is, sampling and equipment considerations, and sampling and analysis protocols. The site also features a chart of dissolved oxygen solubility as a function of temperature.
2.14 Analysis and Design of Feedback Control Systems (MIT)
This course develops the fundamentals of feedback control using linear transfer function system models. It covers analysis in time and frequency domains; design in the s-plane (root locus) and in the frequency domain (loop shaping); describing functions for stability of certain non-linear systems; extension to state variable systems and multivariable control with observers; discrete and digital hybrid systems and the use of z-plane design. Assignments include extended design case studies and cap
