Vibratory Conveyor

Vibratory movements are one of the most ways for conveying and transportation of granular and particulate materials.Vibratory conveyors and feeders with electromagnetic excitation belong to a group of mechatronic devices that in an efficient wayprovides drive force and oscillations for this conveying. They have an important role in framework of the many industrial process inwhich are dominant the particulate materials: food processing, cement production, certain product line in steel industry,pharmaceutical industry, agriculture, etc. Therefore, they are representing a very important element of above mentioned technologicprocesses and production line. Especially, the vibratory conveyors and feeders that operate in the resonant mode are used in industrialapplications because of their energy efficiency increasing. The relatively small input energy of actuator drive causes intensivelyvibrations of load carry element (LCE) of vibratory conveyor. The intensity of the vibrations directly affects on gravimetric flow (massflow) and therefore on the productivity of vibratory conveyors. To ensure a reliable and energy-efficient operation of vibratoryconveyors, it is necessary to have a reliable and accurate measurement and testing of electrical and mechanical quantities. A hardwareand software implementation of the testing and measurement system of resonant vibratory conveyor with electromagnetic drive, andtheir corresponding data acquisition platform are presented in this paper. The experimental results obtained on a real laboratory setupof resonant vibratory conveyor are also shown.

Strip Production

In this paper, the computation method of the strip crown is analyzed using the measured strip thickness data on a hot strip product line. The better quality of the strip is achieved for the smaller crown and the closer of the mean thickness to the nominal thickness. The polynomial approximation method for the transverse thickness distribution of the strip is used, and the different degrees of the polynomial are selected for calculating the strip crown. The calculated results are compared with the output of the measuring system in a rolling factory.

Pentagonal Symmetry

A basic pattern in the body plan architecture of many animals, plants and some molecular and cellular systems is five-part units. This pattern has been understood as a result of genetic blueprints in development and as a widely conserved evolutionary character. Despite some efforts, a definitive explanation of the abundance of pentagonal symmetry at so many levels of complexity is still missing. Based on both, a computational platform and a statistical spatial organization argument, we show that five-fold morphology is substantially different from other abundant symmetries like three-fold, four-fold and six-fold symmetries in terms of spatial interacting elements. We develop a measuring system to determine levels of spatial organization in 2D polygons (homogeneous or heterogeneous partition of defined areas) based on principles of regularity in a morphospace. We found that spatial organization of five-fold symmetry is statistically higher than all other symmetries studied here (3 to 10-fold symmetries) in terms of spatial homogeneity. The significance of our findings is based on the statistical constancy of geometrical constraints derived from spatial organization of shapes, beyond the material or complexity level of the many different systems where pentagonal symmetry occurs.

Fast Disintegrating Tablets

Fast disintegrating tablets (FDTs) have received increasing demand from the last few years and the field has become a rapidly growing field in the pharmaceutical industry. Fast disintegrating tablets (FDTs) are those solid doses form which when put on the tongue gets rapidly dissolved, releasing the drug within a few second without need of water. The development of FDTs have been formulated for paediatric, geriatric and bedridden patients and for active patients who are busy and travelling and may not have access to water. Such formulation provide an opportunity for product line extension in the many elderly persons will have difficulties in taking conventional oral doses forms (viz, solution suspensions tablet and capsules) because of hand tremors and dysphagia. This article focused on ideal requirements, need for development of FDTs, challenges in formulations, suitability of drug candidates superdisintegrants employed, various technologies developed for FDTs. Evaluation methods, and various marketed products.

Dr. Leroy H. (Roy) Smith, Jr. of General Electric is to be honored at a special session of the ASME Turbo Expo 2009 in recognition of his 55 years of contributions to the gas turbine industry. Although best known to his ASME and IGTI colleagues for his many publications on compressor aerodynamic design theory, analysis methods and research, he has made equally impressive contributions to GE’s jet engine product line. This paper gives a brief chronology of his career, then focuses on the many outstanding fan and compressor aero designs he has created for several major GE engine families.

AbstractGiven the many types of suboptimality in perception, I ask how one should test for multiple forms of suboptimality at the same time – or, more generally, how one should compare process models that can differ in any or all of the multiple components. In analogy to factorial experimental design, I advocate for factorial model comparison.
