Despite the predictable longevity of implant prosthesis, there is an ongoing interest to continue to improve implant prosthodontic treatment and outcomes. One of the developments is the application of computer-aided design and computer-aided manufacturing (CAD/CAM) to produce implant abutments and frameworks from metal or ceramic materials. The aim of this narrative review is to critically eval...

model predictive controller is widely used in industrial plants. uncertainty is one of the critical issues in real systems. in this paper, the direct adaptive simplified model predictive control (smpc) is proposed for unknown or time varying plants with uncertainties. by estimating the plant step response in each sample, the controller is designed and the controller coefficients are directly ca...

This article reviews eight proposed strategies for solving the Symbol Grounding Problem (SGP), which was given its classic formulation in Harnad (1990). After a concise introduction, we provide an analysis of the requirement that must be satisfied by any hypothesis seeking to solve the SGP, the zero semantical commitment condition. We then use it to assess the eight strategies, which are organi...

After the fuzziness in Europe that surrounded the implementation of the excessive deficit procedure foreseen by the Stability and Growth Pact (SGP), the European Union had to restore the credibility of the weakened fiscal rule. On March 2005, the 25 members amended the SGP. The constraint was to keep alive the Treaty of Amsterdam, which instituted the SGP. Indeed, an attempt to make major chang...

This paper describes the development of dentin bonding systems, and describes the current strategies for bonding composite resin materials to dentin. Two main strategies are available--total-etch or self-etch--and each has unique advantages and disadvantages. For each category, simplified systems that reduce the number of application steps are available. Currently, the market is moving towards ...
