On optimal relay placement for improved performance in non-coverage limited scenarios
2014
Low power nodes have been a hot topic in research, standardization, and industry communities, which is typically considered under an umbrella term called heterogeneous networking. In this paper we look at the problem of deploying optimally low power nodes in the context of relay networking, when an operator connects low power nodes (or small cells) via the wireless backhaul that uses the same spectrum and the same wireless access technology. We present an analytical model that can calculate optimal coordinates for low power nodes based on the input parameters, such as preferred number of nodes, their transmission power, parameters of the environment etc. The analytical calculations are comp…
Context-aware data caching for 5G heterogeneous small cells networks
2016
In this work, we investigate the problem of context-aware data caching in the heterogeneous small cell networks (HSCNs) to provide satisfactory to the end-users in reducing the service latency. In particular, we explore the storage capability of base stations (BSs) in HSCNs and propose a data caching model consists of edge caching elements (CAEs), small cell base stations (SBSs), and macro cell BS (MBS). Then, we concentrate on how to efficiently match the data contents to the different cache entities in order to minimize the overall system service latency. We model it as a distributed college admission (CA) stable matching problem and tackle this issue by utilizing contextual information t…
Fall Detection Using Location Sensors and Accelerometers
2015
The rapid aging of the world's population is driving the development of pervasive solutions for elder care. These solutions, which often involve fall detection with accelerometers, are accurate in laboratory conditions but can fail in some real-life situations. To overcome this, the authors present the Confidence system, which detects falls mainly with location sensors. A user wears one to four tags. By detecting tag locations with sensors, the system can recognize the user's activity, such as falling and then lying down afterward, as well as the context in terms of the location in the home. The authors used a scenario consisting of events difficult to recognize as falls or nonfalls to comp…
Apperception as a Multisensory Process in Material Experience
2015
Visual perspective has dominated experience research in humantechnology interaction for decades now. The neglect of other sensory modalities is gradually being addressed by scholars and designers, who investigate user experience based on touch, smell, taste, sound and even expressive bodily interactions. In cognitive and affective processes, user experience is always multi-modal, not just regarding perceived multi-sensory information, but also while perceiving through one modality we mentally construct information relevant to the other senses. This article reports the results of an experiment, where participants (N = 52) appraised materials either only by touching them or only by seeing. Th…
Towards proactive context-aware self-healing for 5G networks
2017
In this paper, we suggest a new research direction and a future vision for Self-Healing (SH) in Self-Organizing Networks (SONs). The problem we wish to solve is that traditional SH solutions may not be sufficient for the future needs of cellular network management because of their reactive nature, i.e., they start recovering after detecting already occurred faults instead of preparing for possible future faults in a pre-emptive manner. The detection delays are especially problematic with regard to the zero latency requirements of 5G networks. To address this problem, existing SONs need to be upgraded from reactive to proactive response. One of the dimensions in SH research is to employ more…
Synchronization of hidden chaotic attractors on the example of radiophysical oscillators
2017
In the present paper we consider the problem of synchronization of hidden and self-excited attractors in the context of application to a system of secure communication. The system of two coupled Chua models was studied. Complete synchronization was observed as for self-excited, as hidden attractors. Beside it for hidden attractors some special type of dynamic was revealed.
Three Halves of a Whole : Redefining East and West in UNESCO’s East-West Major Project 1957-1966
2017

 
 
 In 1946 Julian Huxley, UNESCO’s rst Director-General, suggested that two opposing philosophies of life were confronting each other from the East and the West, setting the focus on the cultural aspect of this polarisation and de ning the possibility of an East- West conflict as the main threat to world peace. A decade later, in 1957, UNESCO launched The Major Project on the Mutual Appreciation of Eastern and Western Cultural Values to promote its ideas of intercultural understanding as a means to maintaining peace. The core concepts of the Project, East and West, were not strictly defined. Here East and West, as concepts, fit Reinhart Koselleck’s definition of Grundbegri…
De-demonising Japan? Transitioning from war to peace through Japan’s cinematic post-war cultural diplomacy in UNESCO’sOrientproject 1957–1959
2017
AbstractIn 1959, UNESCO published a film catalogue titled Orient. A Survey of Films Produced in Countries of Arab and Asian Culture to familiarise Western audiences with Eastern cultures. Out of the 139 feature films included in the catalogue, 37 were Japanese. Through a discussion of the descriptions of the films provided in the catalogue, this article analyses Japan’s post-war cultural diplomacy in the context of the Orient project. The aim is to discuss the question of what purpose the Japanese films chosen for the Orient catalogue served in terms of cultural diplomacy. The analysis suggests the Japanese representatives aimed to position the nation in the international arena outside the …
Emerging and Traditional Donors in the ‘Post-Busan’ Context: Assessing Brazil’s and Finland’s Cooperation Practices in Mozambique
2015
At the same time as the ‘emerging donors’ have gained relevance in the development cooperation system, they have also challenged established principles of aid. This article compares Brazil's and Finland's development cooperation practices in the light of recent global tendencies in the aid architecture. Based on empirical research carried out in Mozambique, Brazil, and Finland, the article gives a detailed review of the institutional and historical settings of each bilateral cooperation. The authors then analyse how two central concepts reinforced during the Busan High Level Forum have been put into practice by a ‘new emerging’ and a ‘traditional Nordic’ donor. For ‘development effectivenes…
Democracy, poverty and civil society in Mozambique
2015
National elections were held in Mozambique for the fifth time in October 2014. As a state, Mozambique – like many ‘fourth-wave’ transition countries – fulfils the formal criteria of democracy. But to what extent are the mechanisms of accountability implemented? In Africa, two issues have been identified as key impediments for successful democratic transition: failure to improve the welfare of the poor and the ‘pre-modern’ character of civil society. In Mozambique, robust economic growth has been accompanied by growing inequality, while traditional civil society organisations (CSOs) have become increasingly visible on local level since the political transition in 1994. Based on the analysis …
