We examine the explanatory and predictive power of fundamental macroeconomic and behavioral factors with regards to stock returns of the Dow Jones Industrials Index. With a novel sentiment dataset from over 3.6 million Reuters news articles, we nd signi cant correlations between Reuters sentiment and stock returns. We show with vector autoregression and error correction models that Reuters sent...

We examine the statistical power of fundamental and behavioral factors with regards to stock returns of the Dow Jones Industrials Index. With a novel sentiment dataset from over 3.6 million Reuters news articles, we nd signi cant correlations between Reuters sentiment and stock returns. We show with vector autoregression and error correction models that sentiment can explain and predict changes...

Chong and Ng (2008) find that the Moving Average Convergence–Divergence (MACD) and Relative Strength Index (RSI) rules can generate excess return in the London Stock Exchange. This paper revisits the performance of the two trading rules in the stock markets of five other OECD countries. It is found that the MACD(12,26,0) and RSI(21,50) rules consistently generate significant abnormal returns in...

The first great wave of commercial open source adoption was done by software vendors. Once they realized the quality and time to market competitive advantages of innovating by integrating open source technologies, the trend was unstoppable. The second great wave was the creation of entirely new internet business models based on the scalability of free software. Companies such as Google, Faceboo...

We address the reconstruction of CAD models from 3D point clouds, assuming that an a priori CADmodel, roughly similar to the scene to reconstruct, is given. The problem can be solved using a Bayesian approach which states the reconstruction task as the search of the most probable CAD model. This article presents a reliable cylinder generation algorithm that can be used to efficiently reach the ...

The paper summarize that moisture sensor based on microstrip patch antenna. Microstrip patch sensors have become useful and widely used in every fields such as agricultures, industrials, food products, medicals communication etc. It have been more useful for detecting i.e., broken rice detection, Impurities detection in water, Soil moisture measurement, Rice Grain moisture, Rice quality detecti...

With the development of cloud computing technologies and the multiplication of enterprise architecture reference frameworks, the industrials are encouraged to take into account the new concepts of cloud service in the evolution of their information system strategies. The present paper starts by presenting background concepts and the state of the art of the enterprise architecture, in order to p...

Virtual engineering technologies become an emerging field in industry and research. Nowadays, industrials are using Virtual and Augmented Reality in different phases of their manufacturing process (advanced manufacturing process visualization, assembly tasks, training, etc.). The purpose of this paper is to introduce the advantage of linking augmented reality application, to help employees on t...
