The research at University College London School of Medicine (UCLSM) is supported by the Wellcome Trust, Action Research, the Special Trustees of University College Hospital, and the Muscular Dystrophy Group of Great Britain. The studies have been carried out with the assistance of Dr. P. S. Tofts, Mr. D. Delpy and Mr. A. Chu of the Department of Medical Physics (UCLSM), and Mr. N.Taylor of Kin...

System-initiated digressive proposals may be used to introduce new and unexpected information into automated telephone services. These digressions may be viewed as particularly pronounced forms of unsolicited interruptions as they contain information not directly related to the caller’s intended activity. In human–human conversation, interruptions are considered to be speech acts which intrinsi...

introduction: the aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. methods: three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. results: larger nodules and poros...

A model of investment casting a titanium alloy gearbox based on the ProCAST software was established in this work, and simulated result used to optimize process. The flow temperature field were an actual pouring Casting defects solidification process analyzed. results show that can be predicted by simulation exactly, is accordance with Shrinkage porosity are observably alleviated remodelling mo...

In 1981, Paris and Wilkie [28] indicated it was an open question whether IΣ0 would satisfy the Second Incompleteness Theorem for Herbrand deduction. We will show that some specially formulated axiomizations for IΣ0 can evade the Herbrandized version of the Second Incompleteness Theorem.

In order to reduce the shrinkage porosity of nickel-based superalloy castings in investment casting process, effects different gating systems on mold filling, solidification and prediction aero-engine turbine nozzle were investigated by simulation experimental methods. Results show that design vertical runner would cause greater turbulence melt riser during filling outer is not necessary. With ...

The development of new technologies has confronted the entire domain of science and industry with issues of big data's scalability as well as its integration with the purpose of forecasting analytics in its life cycle. In predictive analytics, the forecast of near-future and recent past - or in other words, the now-casting - is the continuous study of real-time events and constantly updated whe...

The aim of this paper is to examine the concentration of wealth among the group of top wealth holders, defined as those with wealth in excess of a high cut off. The paper begins by considering the definition of this cut off, analogous to the definition of a poverty line at the other end of the distribution. It then considers what can be learned about the proportion classified as ‘rich’ and abou...

As the adaptation of titanium crowns obtained by Rematitan Plus investment, specific for titanium, is not recognized to be suitable, this study evaluated the effect of the concentration of the specific liquid and the temperature of the mold of investments on the internal misfit of crowns cast on commercially pure titanium. Individual dies of epoxy resin were obtained, representing teeth prepare...

Porosities of set and burnout compacts of phosphate-bonded investments were determined. A gas pycnometer was used to measure the volumes, and hence the densities, of fine powders and porous compacts. Porosities of set and burnout compacts were then obtained from these data for as-received powders and dry set compacts by a numerical simulation method, subsequently leading on to the estimated com...
