AIMS AND OBJECTIVES The objective of the present study is to compare the effectiveness of three different processing techniques and to find out the accuracy of processing techniques through number of occlusal interferences and increase in vertical dimension after denture processing. MATERIALS AND METHODS A cross-sectional study was conducted on a sample of 18 patients indicated for complete d...

Resin transfer molding of an inorganic polymer binder was successfully demonstrated in the preparation of ceramic fiber reinforced engine exhaust valves. Unfortunately, in the preliminary processing trials, the resulting composite valves were too brittle for in-engine evaluation. To address this limited toughness, the effectiveness of a modified fiber-matrix interface is investigated through th...

The options for the fibre reinforcement of polymer matrix composites cover a range from short-fibre chopped strand mat, through woven fabric to unidirectional pre-impregnated (prepreg) reinforcements. The modelling of such materials may be simplified by assumptions such as perfect regular packing of fibres and the total absence of fibre waviness. However, these and other features such as the cr...

Filling time and volume fill prediction of long complex parts produced using the method resin infusion is prominent importance. Fibre fraction, reinforcement type composite laminate thickness significantly affect manufacturing behaviour. It crucial to have an estimate fabrication parameters such as filling time. The PAM-RTM (resin transfer moulding) commercial software package makes it possible...

The Radiative Transfer for TOVS (RTTOV) is a widely-used radiative transfer model (RTM) for calculation of radiances for satellite infrared and microwave sensors, including the 8461-channel Infrared Atmospheric Sounding Interferometer (IASI) and the 15-band Advanced Microwave Sounding Unit-A (AMSU-A). In the era of hyperspectral sounders with thousands of spectral channels, the computation of t...

Introduction Nanocontact molding and other related techniques of imprint lithography have received much attention as potentially simple and inexpensive tools for the accurate replication of sub-100 nm features. We have recently reported on the use of this method for the replication of features as a small as 60 nm. In this technique, an inexpensive mold is made by curing a photopolymer resin aga...
