Greek Intelligence Service (NIS-EYP): Past, Present and Future

The end of the Cold War more than a decade ago created a world in which the relative stability between the two superpowers has disappeared. On the other side, the 9/11 terrorist acts in US and consequently in Spain (11/03/2003) and in UK (07/07/2005) exercised a lot of pressure on the intelligences services to adjust to new threats by looking their past and preparing for the future. Without exception, the Greek Intelligence Service (NIS-EYP) is restructuring its tasks in order to be capable of confronting new threats and protect the Greek national security. This article analyzes the historical process of NIS-EYP, points out the new responsibilities of NISEYP (Intelligence Council, Intelligence Bill) and makes suggestions for the future challenges that the Greek intelligence Service has to face in the 21st century

Intelligence Requirements for Cyber Defense, Critical Infrastructure and Energy Security In Greece

The proposed Fusion Centers in the Mediterranean region could be a necessary tool for collective action among the intelligence services depended on shared intelligence and common assessment in order to prevent prospective major terrorist acts against critical infrastructure in our home states

European Intelligence Cooperation: A Greek Perspective

European intelligence cooperation is the most important weapon in the fight against the new threats in the 27 member states. The article emphasizes the reasons that make the European Union Intelligence Analysis Centre (INTCEN) more towards an independent operational agency into the European mechanism as well as the roles of the Intelligence College of Europe founded in France and the European Intelligence Academy established under the auspices of the Research Institute for European and American Studies (RIEAS) in Athens, Greece. Even though, effective intelligence cooperation is hard to achieve even at the national level as different services compete for resources and attention from the decision makers, past terrorist incidents in Europe served as a wake up for the public and private institutions to promote intelligence sharing and cooperation among European Union institutions and Member States

Cyber security incidents and terrorist threats in Greece

The post 11 September 2001 era has changed governments, policy-makers religious leaders, the media and the general public to play both critical and constructive roles in the war against cyber terrorism and asymmetric warfare. As the security and intelligence community inexorably works its way into the 21st century, it faces an unprecedented way of challenges. The chaotic world environment of the post Cold War (Arab Spring, Syria and Libya crises, Iran nuclear issue, Illegal immigration, human trafficking, Islamic radicalization, money laundering and transnational organized crime) offers a wide range of different issues to be understood, and a variety of new threats to be anticipated

Power system static and dynamic security studies for the 1st phase of Crete Island Interconnection

The island of Crete is currently served by an autonomous electrical system being fed by oil-fired (Heavy fuel or light Diesel oil) thermal power plants and renewables (wind and PVs). The peak load and annual electric energy consumption are approximately 600 MW and 3 TWh respectively; wind and photovoltaic parks contribute approximately 20% of the electricity needs of the island. Due to the expensive fuel used, the Cretan power system has very high electric energy generation cost compared to the Greek mainland. On the other side the limited size of the system poses severe limitations to the penetration of renewable energy sources, not allowing to further exploit the high wind and solar potential of the island. According to the Ten Year Network Development Plan (TYNDP) of the Greek TSO (Independent Power Transmission Operator S.A. IPTO S.A.), the interconnection of Crete to the mainland Transmission System of Greece will be realized through two links: A 150 kV HVAC link between the Peloponnese and the Crete (Phase I) and a HVDC link connecting the metropolitan area of Athens with Crete (Phase II). The total length of submarine and underground cable of the HVAC link will be approximately 174km; it is at the limits of the AC technology and the longest and deepest worldwide at 150 kV level. A number of studies have been conducted by a joint group of IPTO and Hellenic Electricity Distribution Network Operator (HEDNO) for the design of this interconnection. This paper presents briefly the power system static and dynamic studies conducted for the design of the AC link and its operation. Firstly, the paper presents the main results of the static security study regarding the calculation of the maximum power transfer capability of the link and the selection of the reactive power compensation scheme of the cable. Results from dynamic security analysis studies are also presented. The small-signal stability analysis concludes that a new (intra-area) electromechanical oscillation is introduced to the National System after the interconnection. The damping of the electromechanical oscillations is sufficient; however the operation of power system stabilizers at power plants located both at the mainland and at Crete power system can increase significantly the damping of important oscillation modes. Finally with respect to the risk of loss of synchronism after a significant disturbance in the system of Crete, such as a three-phase fault (“transient stability”)- enough safety margin is estimated by means of Critical Clearing Time calculations

Multivariate statistical process control based on principal component analysis: implementation of framework in R

The interest in multivariate statistical process control (MSPC) has increased as the industrial processes have become more complex. This paper presents an industrial process involving a plastic part in which, due to the number of correlated variables, the inversion of the covariance matrix becomes impossible, and the classical MSPC cannot be used to identify physical aspects that explain the causes of variation or to increase the knowledge about the process behaviour. In order to solve this problem, a Multivariate Statistical Process Control based on Principal Component Analysis (MSPC-PCA) approach was used and an R code was developed to implement it according some commercial software used for this purpose, namely the ProMV (c) 2016 from ProSensus, Inc. (www.prosensus.ca). Based on used dataset, it was possible to illustrate the principles of MSPC-PCA. This work intends to illustrate the implementation of MSPC-PCA in R step by step, to help the user community of R to be able to perform it.FCT - Fundação para a Ciência e a Tecnologia(UID/CEC/00319/2013
