Summary Following the influential work of Nelson and Plosser (1982) stochastic trends in macroeconomic time series are considered to be a stylized fact. However, since the stochastic trend hypothesis can be rejected for many economic series if a segmented trend model is considered as an...

Summary Starting from today’s definition of innovation indicators, this paper analyses the dynamic relationships between innovation activities (approximated by two innovation input indicators and one innovation output indicator) and per capita income in Germany for the two periods from 1850...

Summary We analyse German public finances against a theoretical background using a unique database, retrieved from multiple sources covering the period between 1850 and 2010.Multiple currency crises and force majeure offer anecdotal evidence contradicting the historical perception of Germany...

This paper assesses empirically two competing unemployment theories.

In this paper, the authors propose a new approach based on the detection of opinion by the SentiWordNet for the production of text summarization by using the scoring extraction technique adapted to detecting of opinion. The texts are decomposed into sentences then represented by a vector of...

This article describes how differential power analysis has laid the foundations of such an attack that has challenged the security of almost all cryptosystems like DES, AES, and RSA. This non-invasive attack first extracts the power consumption details from devices embedded with cryptographic...

Predictive analytics can forecast trends, determines statistical probabilities and to act upon fraud and security threats for big data applications. Predictive analytics as a service (PAaaS) framework based upon ensemble model that uses Gaussian process with varying hyper parameters, Artificial...
