Although the response of undamped or at least proportionally damped linear systems can be determined easily by modal analysis, the prediction of the response of nonproportionally damped linear systems requires either more ...

Available approaches to statistical forecasting suffer from several deficiencies (problems) that render their predictions for real-world economic/business series inappropriate. In this paper I illustrate such deficiencies, ...

Greece and Greek firms are behind their counterparts in advanced countries. This paper discusses the situation of Greek firms and proposes various strategies to be able to more successfully compete in the emerging new economy.

Marketing communication has taken a new approach towards the consumers due to the vast transition and interaction of technology in our daily lives. After introducing the relevant factors stating the importance of mobile ...

The increasing necessity to solve complex problems in Structural Dynamics and Earthquake Engineering requires the development of new ideas and innovative methods for providing accurate numerical solutions in affordable ...

This study focuses on the development of a new methodology for the selection of the best solution for municipal solid wastes disposal, after evaluating all the important factors, including economical, social and environmental ...

This work aims to constitute an algorithmic framework for the automatic creation of compression only forms of generative space shells. In particular the case of concrete dams is investigated, where the loading is non-uniform ...

The SIBYL/RUNNER interactive forecasting system is a comprehensive package of time-shared computer programs that seek to handle four essential forecasting functions. The first is screening alternative forecasting techniques ...

Supply Chain Management is in the core of businesses’ operational activities worldwide. Its main purpose is the proper management of resources and the assurance of the sustainable operation of the economic entities. However, ...

Prelemenary free hull girder vibration study of offshore patrol vessel of Hellenic Navy

VaR (value-at-risk) estimates are currently based on two main techniques: the variance-covariance approach or simulation. Statistical and computational problems affect the reliability of these techniques. We illustrate a ...

This paper describes and applies a nonparametric model for pricing multivariate contingent claims. Multivariate contingent claims are contracts whose payoffs depend on the future prices of more than one underlying variable. ...

Within the project NOPTILUS, a fully functional system/methodology had been developed that allows the cooperative, fully-autonomous navigation of teams of AUVs when deployed in Static or Dynamic Underwater Map Construction ...

Current multi-AUV systems are far from being capable of fully autonomously taking over real-life complex situation-awareness operations. As such operations require advanced reasoning and decision-making abilities, current ...

Biomedical research and clinical decision depend increasingly on a number of authoritative databases, mostly public and continually enriched via peer scientific contributions. Given the dynamic nature of data and their ...

This paper proposes a new method for visual multimedia content encryption using Cellular Automata (CA). The encryption scheme is based on the application of an attribute of the CLF XOR filter, according to which the original ...

With the recent evolution of technology, the number of image archives has increased exponentially. In Content-Based Image Retrieval (CBIR), high-level visual information is represented in the form of low-level features. ...

In this work, the nonlinear analysis of an existing industrial steel structure (Sodium building), and its retrofitting using SSCD dampers is demonstrated. Specific numerical complications of incremental dynamic (IDA) and ...

Background and aims: Increased nurse-physician collaboration is a factor in improved patient outcomes. Limited autonomy of nurses has been proposed as a barrier to collaboration. This study aims to explore nurse-physician ...
