In this research a fuzzy model is developed for a rotary dryer. It is applied to the pilot plant rotary dryer located in the Control Engineering Laboratory at Oulu University. Firstly, a literature review looking at the current situation of fuzzy modelling and comparison of different methods is done. One modelling method is then applied to the building of the model from data. The rule parameter...

Self-induced rotary sloshing caused by an upward off-centered jet in a cylindrical container is numerically and experimentally investigated. Unlike the regular jet-induced rotary sloshing, the present off-centered case could contain components of higher fluctuation in the surface wave and the amplitude exhibits different values in various view angles. A simple geometrical model for the amplitud...

INTRODUCTION The purpose of this study was to evaluate the efficacy of three methods in removal of Resilon/new Epiphany self-etch (SE) soft resin endodontic obturation system. MATERIALS AND METHODS Thirty extracted single rooted human teeth were prepared for endodontic treatment and obturated with Resilon/Epiphany SE. The roots were randomly divided into three groups; group 1 roots were retre...

A study on the dynamic behaviour of a rotary table transfer machine is discussed in this paper. Part modelling is performed through the application of finite element techniques. Experimental modal analysis is exploited for substructure updating. The assembled model is obtained using constraint equations and boundary conditions. Design modifications are proposed to enhance the dynamic behaviour ...

In order to evaluate the efficiency of heave compensation in the Ocean Drilling Program, we developed a device measuring the acceleration of the core barrels. First results show that heave compensation limits bit motion to 10% of the surface heave. We also use the acceleration data to characterize the formation. On rotary corers, acceleration amplitudes decrease with increasing hardness of the ...

This paper refers to the development of new type rotary compressors suspended with twin springs in a lo~ s1de pressure shell. We compared several types of compress~rs, for example h1gh side pressure shell type, low side pressure shell type, external-suspended type, internal-suspended type, and so on, from the viewpoint of noise reduction, vibration control and transient phenomena such as start-...

The relatively new technology of rotary gas-liquid separation has been advanced by the development of a rotating centrifugal separator closely coupled to a centrifugal turbocompressor. This development by a major equipment manufacturer included the creation and calibration of an integrated design suite, and the use of this tool to optimize a separator/compressor stage. The compression and separ...

The Air Operations Simulation Centre (AOSC) is part of Air Operations Division (AOD) of the DSTO Aeronautical and Maritime Research Laboratory (AMRL), situated at Fishermens Bend in Melbourne. The centre consists of high fidelity visual displays, computer systems driving advanced image generators and various simulation cockpits of Australian Defence Force (ADF) fixed and rotary wing aircraft. T...

Introduction: Root canal instrumentation is an important phase in root canal therapy. Since success in endodontic treatment depends on file defect and fracture, the aim of this study was to compare the evaluation of defect and fracture in rotary and reciproc files in severe curved root canals. Materials & Methods: In this experimental study, 60 mesial canals of human closed apex molars with ...
