The algebraic relationship between predicates and predicate transformers is considered. A canonical decomposition property of transformers is used to develop a typing mechanism for predicate transformer process models based on the input and output interfaces of the processes. Predicate transformers are typed according to the variables read from or written to by the process described by the pred...

  Objective: Considering the use of triple antibiotic paste (TAP) for root canal treatment of open apex teeth, this study aimed to assess the effect of TAP and calcium hydroxide (CH) on bond strength of composite to dentin.   Methods: This in-vitro study was conducted on 32 extracted human premolar teeth. After disinfection with 2% thymol solution, the enamel on the buccal surface of specimens ...

—Field experience indicates that ferroresonance events occur more readily with low-loss distribution transformers, compared to distribution transformers with conventional loss levels. Extensive testing of a large number of transformers has shown a very strong and direct correlation between transformer core loss and the amount of capacitance needed to sustain a ferroresonant condition. A heurist...

The aim of this chapter is to calculate confidence intervals for the maximum power consumption per customer where it is not measured. The motivation behind this computation is to size with more accuracy, distribution transformers. Indeed, losses by hysteresis and by eddy currents being proportional to the volume of the magnetic circuit, it would be interesting to reduce the transformers size. B...

The correspondence between up-closed multirelations and isotone predicate transformers is well known. Less known is that multirelations have also been used for modelling topological contact, not only computations. We investigate how properties from these two lines of research translate to predicate transformers. To this end, we express the correspondence of multirelations and predicate transfor...

This paper investigates the the development and evolution of concepts and the management of transformers, which adds semantics to the concepts. We illustrate how concepts, their variants and transformers can be developed via cooperation. In order to meet increasing user demands for more various software systems, we are revising the software developing process to accommodate mass customisation b...

Background and Aim: Considering the increasing use of antibiotics in root canal therapy and the possible effects of intracanal medicaments on the bond strength of composite restorations, the aim of this study was to evaluate the effect of triple antibiotic paste (TAP) on shear bond strength of three types of composite resins to dentin. Materials and Methods: In this in-vitro, experimental st...

Power transformers are located in the electrical transmission and distribution networks where different voltage levels needed. The turn ratio of low high windings is mechanically controlled by an on-load tap changer or de-energized changer. As transformer’s only moving part, it highly susceptible to mechanical failure aging degradation. While some diagnostic tools have been used determine condi...
