13. Analysis of roll stack deflection in a hot strip mill
Predictive models are required to provide the bending set point for bending for the flatness control devices at rolling stands of finishing mill of Hot Strip Mill (HSM). A simple model for roll stack deflection at the finishing mill has been illustrated where a modified Misaka’s equation has been used to obtain mean flow-stress. Investigation has been perf

14. Entre tem ar: O espectador dentro e fora do quadro
This dissertation named (Coming, theres enough air) is a visual poetics research project in witch artistic practice a theory investigation intersect. A whole of works (drawings, paintings and installation art) executed by the artist between 1999 and 2005 constitutes the object of study. The painting and the surface, making possible the meeting between the vi

15. Design and commissioning of an intelligent robotic saw system for assisting osteotomy surgery.
An orthopaedic saw design and commissioning to be driven by a robot was envisaged based on the requirement to develop a system that would allow a physician to automate some surgical procedures that involve limb manipulation. The project goal is to design and build a proof-of-concept prototype employing both mechatronics and Integrated Product Design techniqu

16. Flatness measurement system / Sistema para medição de erro de planicidade
A acuracidade dos processos de medição e de montagem que utilizam os desempenos como referência depende principalmente da planicidade dessas superfícies. Se a referência está fora das especificações é inútil utilizar instrumentos sofisticados e de alta acuracidade. Neste trabalho é apresentado um sistema para medição de desvios de planicidade de

17. Estudo do processo de cristalização de soluções impuras de sacarose por resfriamento
The objective of this work was to study the crystallization kinetics of impure sugarcane sucrose solutions by cooling, prepared as of VVHP and VHP raw sugars, sugarcane syrup and for PP-45 high purity granulated sugar (reference sample), as a part of technology development work for high purity sugar production. The applied methodology was that one proposes b

18. Alternative dark energy models: an overview
A large number of recent observational data strongly suggest that we live in a flat, accelerating Universe composed of ~ 1/3 of matter (baryonic + dark) and ~ 2/3 of an exotic component with large negative pressure, usually named Dark Energy or Quintessence. The basic set of experiments includes: observations from SNe Ia, CMB anisotropies, large scale struct

19. Night blindness, characteristic facies, and skeletal abnormalities in two brothers.
Two brothers are described with a similar physical appearance characterised by minor periorbital anomalies, malar flatness, a maxillary overbite, retrognathia, sloping shoulders, joint hyperextensibility, and minor radiological anomalies. In addition, they had a slowly progressing night blindness, myopia, and extinguished electroretinograms. The mother had m

20. Homological properties of rings of functional-analytic type.
Strong flatness properties are established for a large class of functional-analytic rings including all C*-algebras. This is later used to prove that all those rings satisfy excision in Hochschild and in cyclic homology over almost arbitrary rings of coefficients and that, for stable C*-algebras, the Hochschild and cyclic homology groups defined over an arbi

21. Use of Inorganic Membrane Filters (Anopore) for Epifluorescence and Scanning Electron Microscopy of Nanoplankton and Picoplankton †
Inorganic membrane filters (Anopore) were examined qualitatively by epifluorescence and scanning electron microscopy to determine their suitability for the study of nanoplankton and picoplankton. Compared with filters currently used, the Anopore filters allowed for increased resolution of the specimen with epifluorescence microscopy because of filter flatnes

22. Direct structure analysis in protein electron crystallography: crystallographic phases for halorhodopsin to 6-A resolution.
The crystal structure of halorhodopsin was determined in (centrosymmetric) projection to 6-A resolution by direct methods that use only the amplitudes of the electron diffraction pattern. A multisolution technique was used to generate initial 15-A-resolution basis sets, and after selection of the best phase set (by the closest match of magnitude of Eobs and

23. The Polynesian head: growth and form.
We consider the cranial base to be the primordial determinant of the head form and mandibular shape so common amongst (but not exclusive to) adult Polynesians. The flatness of the cranial base manifests its full influence only when growth of the upper facial skeleton is complete in early adulthood. We argue that during growth and maturation the upper facial

24. Measurement of the spectral directivity of optoacoustic and ultrasonic transducers with a laser ultrasonic source
Comprehensive characterization of wideband ultrasonic transducers and specifically optoacoustic detectors is achieved through the analysis of their frequency response as a function of the incident angle. The tests are performed under well-defined, repeatable operating conditions. Backillumination of a blackened, acoustically matched planar surface with a sho
