Jewellery investment casting machines [PDF]
Gold Bulletin, 1979 Investment casting is by far the most widely used technique for the production of gold jewellery. Each year, large quantities of carat gold alloys are processed by this method. It is therefore of importance that machines used for jewellery investment casting should meet the efficiency and quality standards expected in large scale manufacturing ...

Coded Caching with Heterogeneous User Profiles [PDF]
arXiv, 2022 Coded caching utilizes pre-fetching during off-peak hours and multi-casting for delivery in order to balance the traffic load in communication networks. Several works have studied the achievable peak and average rates under different conditions: variable file lengths or popularities, variable cache sizes, decentralized networks, etc.

Dental Materials Journal, 2003 Part I of this study presented a hypothesis that the thermal expansion of gypsum-bonded investment should become higher under heating conditions favorable for the formation of ahemihydrate. The present study aimed at proving this hypothesis by simulating the rapid heating condition employed in the quick casting technique.

Early Predictions of Movie Success: the Who, What, and When of Profitability [PDF]
, 2015 This paper proposes a decision support system to aid movie investment decisions at the early stage of movie productions. The system predicts the success of a movie based on its profitability by leveraging historical data from various sources. Using social network analysis and text mining techniques, the system automatically extracts several groups of ...

Empirical Macroeconomics and DSGE Modeling in Statistical Perspective [PDF]
arXiv, 2022 Dynamic stochastic general equilibrium (DSGE) models have been an ubiquitous, and controversial, part of macroeconomics for decades. In this paper, we approach DSGEs purely as statstical models. We do this by applying two common model validation checks to the canonical Smets and Wouters 2007 DSGE: (1) we simulate the model and see how well it can be ...
