Combining ASTER multispectral imagery analysis and support vector machines for rapid and cost-effective post-fire assessment : A case study from the Greek wildland fires of 2007

Remote sensing is increasingly being used as a cost-effective and practical solution for the rapid evaluation of impacts from wildland fires. The present study investigates the use of the support vector machine (SVM) classification method with multispectral data from the Advanced Spectral Emission and Reflection Radiometer (ASTER) for obtaining a rapid and cost effective post-fire assessment in a

Use of Satellite Remote Sensing for Detecting Archaeological Features: An Example from Ancient Corinth, Greece

During the last few decades, satellite remote sensing has proven to be an important non-invasive method for archaeological research in order to detect ancient sites and manage existing ones. Archaeologists have tried in the recent past to embed Geographic Information Systems (GIS) and image processing techniques in their research as non-destructive approaches, which can allow a wider perception o

The power of memory and the political dialogue in Greece : The rise of radicalism

This study explores the contexts in which the conflict evolved and how history was perceived, narrated and used by institutions, communities and individuals who sought to influence public opinion and policymakers. The theoretical point of departure is the concept of collective memory, defined as the totality of discourses through which a society makes sense of itself, the present and the future th

PUBLIC PERCEPTIONS ABOUT NATO BRAND: THE CASE OF GREEK GENERATION Z

During the 21st century, public diplomacy and branding received a new angle and application closely related with the meaning of securitization. Even though the importance of this meaning, researchers nowadays notice a research gap considering the three above-mentioned fields. NATO, as a popular security brand, represents an under-researched sui generis organization that gets involved with securiti

Efficient Barrier Option Greeks using Automatic Differentation

K¨anslighetsanalys av barri¨aroptioner med algoritmisk derivering F¨or att f˚a ut optionspris och derivator p˚a priset med avseende p˚a tex r¨anta och volatilitet, utf¨ors vanligtvis ett antal simuleringar varp˚a ett medelv¨arde r¨aknas ut. D¨arefter r¨aknas derivatorna ut med en finit differensmetod. F¨or att erh˚alla tillf¨orlitliga resultat med denna metod kr¨avs ett stort antal simuleringar viAutomatic Differentiation (AD) is an effective method for calculation of derivatives. It can evaluate an unlimited number of derivatives to a fixed cost relative to the computing time of the original function. The AD technique is used in many fields for large and complex calculations in order to get accurate values of derivatives fast. Banks and other financial institutions handle calculations of

Testing for unit roots in the presence of structural change IRAN – GREECE CPI case

In this thesis we consider different tests for unit roots in the presence of structural change. We present the theory that lies behind unit roots, what we mean by structural change and try to detect the instances that “breaks” occur in the data. When performing a unit root test, when there is a structural change the results are biased toward accepting a unit root. Therefore, special care must be t

Potential of a post-classification change detection analysis to identify land use and land cover changes : a case study in northern Greece

Användandet av fjärranalysdata är en viktig metod för att bestämma markanvändning och visa på förändringar i marktäcke. Fjärranalys kan ge en bättre utgångspunkt för övervakning av markytstäcke. Det gör det möjligt att geografiskt lokalisera förändrade markområden för att vidare kunna utföra noggrannare undersökningar om miljöförändringar (t.ex. markdegradering). Studieområdet är ett administrativThe use of remotely sensed data is an important method to indicate land use and land cover changes. Remote sensing can provide a better picture of monitoring land use and land cover changes. It makes it feasible to locate geographically changed areas in order to employ it further detailed studies on environmental changes (e.g. land degradation). The study area is a heterogeneous and small-structur

Stories of Resistance in Greek Street Art : A Cognitive-Semiotic Approach

In line with cognitive semiotics, this paper suggests a synthetic account of the important but controversial notion of narrative (in street art, and more generally): one that distinguishes between three levels: (a) narration, (b) underlying story, and (c) frame-setting. The narrative potential of street art has not yet been considerably studied in order to offer insights into how underlying storie

A Roof for the atrium of the House of the Greek Epigrams in Pompeii? A Three-Dimensional Critical Study

Over the last few decades, a critical revision of prior scholarship concerning Roman domestic space has led to the reappraisal of the traditional account of the atrium suggesting a possibility for this space to be ‘unroofed’. Accordingly, scholars have proposed to look for a convergence of impulses previously cultivated in isolation combining new theoretical frameworks, and a careful examination o

Coming to Light : Illuminating the House of the Greek Epigrams in Pompeii

In recent decades, studies of Roman domestic space have proliferated. The result is a rich but impenetrable picture, with scholars often favoring the use of ancient sources on one hand and finds from excavated houses or material remains on the other. Studies have emphasized how light can be approached to investigate space and its social meaning. At the same time, in the field of digital technologi

Quantifying dire evacuations in case of wildfire using trigger boundaries and case study of the 2018 Mati wildfire in Greece

Wildfire evacuation is a life-saving measure of last resort, but delays can lead to dire outcomes, putting people at risk of fire entrapment. The success or failure of an evacuation depends on the relative speeds of the wildfire and the evacuation, and this varies across communities and wildfires. Despite the importance of understanding this dynamic, no formal framework exists to define or quantif

Dispatches from Greece: ‘‘We were sleeping as Individuals and we woke up as Citizens’’

The universalistic understanding of the subject embedded in the Liberal and Marxist traditions together with contrasting accounts of unconstrained agency fail to explain the contingencies of ground responses that call for social change. The paper makes a case for the opening of the understanding of the human subject when placed in the theoretical terrain of radical political philosophy elaborated

Multicriteria Evaluation in Real Estate Land-use Suitability Analysis: The case of Volos, Greece

The integration of Geographic Information Systems (GIS) into real estate analysis has long been considered an interesting interdisciplinary pursuit, but has yet to become mainstream. Despite the increasing academic focus over the last twenty years, this endeavour has mostly been approached from the scientific side of Geography. Inversely, such focus from the real estate sector remains marginal. No
