a resilient soft liner (rsl) has been used in processed complete dentures but controlling its thickness has always been a challenge because of uneven reduction of the denture's intaglio surface. use of a thermoplastic vacuum-formed template and an endodontic k-file, as guides, for the reduction of a processed mandibular complete denture to receive rsl is described in the present report. a proce...

1  Abstract—Linear constraint transformation is an essential step to solve the forbidden state problem in Petri nets that contain uncontrollable transitions. This work studies the equivalent transformation from a legal-marking set to its admissible-marking set given such a net. First, the concepts of an escaping-marking set and a transforming marking set are defined. Based on them, two algorit...

A practical and robust inter-domain marking scheme for IP traceback is proposed. We first identify six drawbacks of Probabilistic Packet Marking (PPM), and then contrive a synergic scheme to address all of them. To relieve the victim from the daunting computational overhead, we derive the optimal marking probability with respect to the number of packets required for path reconstruction, and exp...

Over the past decade, thermoplastics have been used as alternative substrates to glass and Si for microfluidic devices because of the diverse and robust fabrication protocols available for thermoplastics that can generate high production rates of the desired structures at low cost and with high replication fidelity, the extensive array of physiochemical properties they possess, and the simple s...

A polymer blend is a mixture of two or more polymers that have been blended together to create a new material with different physical properties. Generally, there are five main types of polymer blend: thermoplastic–thermoplastic blends; thermoplastic–rubber blends; thermoplastic–thermosetting blends; rubber– thermosetting blends; and polymer–filler blends, all of which have been extensively stu...

Background: Treatment of minor malocclusions with clear thermoplastic aligners is more commonly being used as an aesthetic alternative to fixed appliances. This can be done by manually resetting teeth on a plaster model or by models generated from a 3D computer model (Invisalign®). However, little research has been performed on the complex force systems generated by these types of appliances. O...

Marking student responses to short answer questions raises particular issues for human markers, as well as for automatic marking systems. In this paper we present the Amati system, which aims to help human markers improve the speed and accuracy of their marking. Amati supports an educator in incrementally developing a set of automatic marking rules, which can then be applied to larger question ...
