In recent years, optical manipulation has gained increasing interest, especially in combination with microfluidics. The contamination-free handling of micrometer-sized particles without any mechanical contact is an attractive tool for biology and medicine. VCSELs (vertical-cavity surface-emitting lasers) are an excellent choice for the trapping lasers, offering the opportunity of miniaturizatio...

This article presents a model for handling multiresolution animation of complex deformable models. An octree-based animation method is described, along with the set of algorithmic tools, that allow for real-time interaction on complex objects. Some efficient collision detection scheme is also described for deformable objects. A method is presented for timeguaranteed mechanical simulation, that ...

SUMMARY This Technical Memorandum provides a comprehensive and critical review of the available literature on the primary processing, storage and quality of fresh lowbush (wild) blueberries (Vaccinium angustifolium Ait. and V. myrtilloides Michx.). Areas of discussion include: pre-process cooling, mechanical damage, washing, storage temperature and quality parameters. Recommendations for furthe...

30 INTERNATIONAL DENTISTRY – AUSTRALASIAN EDITION VOL. 7, NO. 2 Nanotechnology, on the other hand, has made successful inroads into modern composite technology and continues to be the subject of considerable research work1,12,13. Nanosized inorganic fillers enable the filler content of composite pastes to be maximised while retaining excellent clinical handling properties and at the same time m...

CAMES (computer-aided mechanical expert system) is a tool for automatically designing material-handling equipment used in pulp and paper mills. Operational since 1988, it has designed over 700 machines in a total of 5 classes and, consequently, has influenced our principles for deploying all knowledge-based systems. Because it is being extended to other machines within our group of companies, i...

The rotary valve is a widely used mechanical device in many solids-handling industrial processes. However, it may also be responsible for most of the attrition effects occurring in a typical process. In this study, the attrition effects occurring in a rotary valve operating as a stand alone device and as part of a pneumatic conveying system are investigated. The Gwyn’s correlation was found to ...

The main contribution of the paper is the development of an adaptive backstepping controller for a nonlinear hydraulic-mechanical system considering valve dynamics. The paper also compares the performance of two variants of an adaptive backstepping tracking controller with a simple PI controller. The results show that the backstepping controller considering valve dynamics achieves significantly...

High-energy ball milling was used to prepare sets of mechanical alloys in the systems Al–Mg, Al–Mg–H, B–Mg, and Ti–B. X-ray diffraction, electron microscopy, and low-angle laser diffraction were used to characterize structures, morphology, and sizes of the alloys, respectively. The produced materials were metastable and nanocrystalline; the particle sizes were in the range of 1–501m. A constant...

Worldwide, about 15 million infants are born prematurely each year. Technological advances, including invasive mechanical ventilation, play a major role in the survival of extremely preterm babies. Those who survive may have prolonged morbid conditions that result in long-term sequelae. Nurses face several challenges during the hospitalization of these infants. Vigilant care, monitoring, and ca...
