Kaplan - Funkfeuer Abstract The CONFINE project studies community networks and has developed a testbed to allow experi- mentation with community networks. To evaluate the testbed and to stimulate broad adoption of community networks research, the project includes two open calls for participation. A second open call was launched in project year 4. Nine partners were selected to do research on and with commu- nity networks, supported by the project. This deliverable gives a summary of experiences and results from this second open call. In the COSMOS project (CrOwd-Shared Mesh netwOrk for universal internet Service), the University of Cambridge and the Leibniz Universitat¨ Hannover investigate the benefits of extending the coverage of any crowd-shared network (e.g. the PAWS network in Nottingham, UK) by connecting the home routers as a mesh. The Technische Universitat¨ Berlin implemented a cross-layer joint power and rate controller, Minstrel-Blues, which enables realising different power control approaches using today’s WiFi hard- ware. Routek created software, called the Network Characterisation Daemon or NCD, an interactive tool that provides users of community networks a means of monitoring, evaluating and fine-tune their network nodes. In the BTC (“Blessing of The Commons”) project, the Telecommunications Research Center Vi- enna has built a dedicated interference measurement testbed using software-radio front-ends as signal transmitters. Additionally, the Linux kernel driver code has been modified and selected user-space tools have been implemented to allow keeping track of the instantaneous channel load and spectral efficiency characteristics for every link in the network. Itinirarium and the Institute of Government and Public Policies of the Autonomous University of Barcelona, in the CitizenSqKm project, explored how a community reacts to a new platform where digital information is created, collected, guarded, processed and disseminated by citizens in a collec- tive and structured effort. The New America Foundation has made a contextual analysis of community network sustainability. They have developed a broad-based framework for understanding socioeconomic factors that deter- mine the success, sustainability and social impact of community networks. In The Icarus project, the University of the Western Cape has performed a case study on a community network in rural South Africa. The impact of connecting the community network to the Internet has been investigated and show how this is instrumental to develop and reinforce other social structures within the community. In CONFLATE (CONFINE extension towards OpenFlow experimentation: infrastructure, soft- ware and demonstrations), UNIDATA and the Consorzio Nazionale Interuniversitario per le Telecomuni- cazione have expanded the Community-Lab testbed in two dimensions: infrastructural and functional by deploying new Community-Lab research devices in the Ninux.org network in Rome and by allow- ing researchers to deploy OpenFlow experiments in Community-Lab. Finally, Sarantaporo.gr has expanded its community wireless network and interconnected islet vil- lages via a backbone infrastructure. Furthermore, it has expanded to the nearest technical institute and through this to other community networks all over Europe. Contents I. Technological experiments8 1.

Fragoulis a,*, M.G. Stamatakis b, D. Papageorgiou a, E. Chaniotakis a a TITAN Cement Company S.A. Kamari Plant, P.O. Box 18, Elefsina 19 200, Attica, Greece b Department of Geology, National University of Athens, Panepistimiopolis, Ano Ilissia, 157 84 Athens, Greece Abstract The aim of the present study is to test diatomite rocks as alternative pozzolanic materials that could be used for the manu- facturing of pozzolanic cements in Greece. The diatomite rocks used occur in Samos Island and in the Elassona, Greece. The Samos diatomites were mainly consisted of calcite and opal-A, whereas the Elassona diatomite consisted of opal-A, clay minerals, feldspars and quartz. As a result, the Samos samples were rich in CaO and SiO2, while the Elassona ones were rich in SiO2,Al2O3 and Fe2O3. The specific surface of the laboratory-produced cements was high, with the grindability of the Elassona diatomites being lower than that of Samos. The water demand of all blended cements was higher than that of the laboratory produced OPC. The late com- pressive strength of most diatomite cements studied was improved with respect to the lab OPC. Ó 2004 Elsevier Ltd. All rights reserved.

KORSÓS Dorottya Angyal and Dr. Zoltán Korsós, Department of Zoology, Hungarian Natural History Museum, H-1088 Budapest, Baross u. 13., E-mails: [email protected], [email protected] Abstract. Twelve caves of Western Mecsek, Southwest Hungary were examined between September 2010 and April 2013 from the millipede (Diplopoda) faunistical point of view. Ten species were found in eight caves, which consisted eutroglophile and troglobiont elements as well. The cave with the most diverse fauna was the Törökpince Sinkhole, while the two previously also investigated caves, the Abaligeti Cave and the Mánfai-kőlyuk Cave provided less species, which could be related to their advanced touristic and industrial utilization.

  • Balkan Wars Between the Lines: Violence and Civilians in Macedonia, 1912-1918
    ABSTRACT Title of Document: BALKAN WARS BETWEEN THE LINES: VIOLENCE AND CIVILIANS IN MACEDONIA, 1912-1918 Stefan Sotiris Papaioannou, Ph.D., 2012 Directed By: Professor John R. Lampe, Department of History This dissertation challenges the widely held view that there is something morbidly distinctive about violence in the Balkans. It subjects this notion to scrutiny by examining how inhabitants of the embattled region of Macedonia endured a particularly violent set of events: the Balkan Wars of 1912-1913 and the First World War. Making use of a variety of sources including archives located in the three countries that today share the region of Macedonia, the study reveals that members of this majority-Orthodox Christian civilian population were not inclined to perpetrate wartime violence against one another. Though they often identified with rival national camps, inhabitants of Macedonia were typically willing neither to kill their neighbors nor to die over those differences. They preferred to pursue priorities they considered more important, including economic advancement, education, and security of their properties, all of which were likely to be undermined by internecine violence. National armies from Balkan countries then adjacent to geographic Macedonia (Bulgaria, Greece, and Serbia) and their associated paramilitary forces were instead the perpetrators of violence against civilians. In these violent activities they were joined by armies from Western and Central Europe during the First World War. Contrary to existing military and diplomatic histories that emphasize continuities between the Balkan Wars of 1912-1913 and the First World War, this primarily social history reveals that the nature of abuses committed against civilians changed rapidly during this six-year period.

Get inspired. Sarantaporo.gr Community Wireless Network: a short version of our story We came together as a team in the Summer of 2010 to promote our village, Sarantaporo, Elassona municipality. To do this we started creating a website. In the process we realized that the website was unreachable by the people of our village because they did not have Internet access. In the year 2010, an entire region around our village, was living in the shadow of digital isolation. Soon we realized that this shortcoming was not just a "privilege" of our own village. Thousands of remote, rural areas across Europe and the world, half the world's population in fact, remain “unconnected” even as we speak. We are not accustomed to passivity. We do not expect others to solve our problems. From early childhood we were a very creative companionship. Once more, driven by a creative attitude, we set forth to solve the problem of our village. For us it was not a time to despair, but an opportunity to give something back to the place of our childhood. Looking for solutions in other communities, such as the free software realm, the hackerspaces and elsewhere, we learned about community networks. Making the most of freely shared information by online communities and guidance from people with the relevant Building telecommunications infrastructure as a commons 3 expertise we managed to build our own wireless community network, Sarantaporo.gr.
