Modelling Recurrent Events for Improving Online Change Detection

2016

The task of online change point detection in sensor data streams is often complicated due to presence of noise that can be mistaken for real changes and therefore affecting performance of change detectors. Most of the existing change detection methods assume that changes are independent from each other and occur at random in time. In this paper we study how performance of detectors can be improved in case of recurrent changes. We analytically demonstrate under which conditions and for how long recurrence information is useful for improving the detection accuracy. We propose a simple computationally efficient message passing procedure for calculating a predictive probability distribution of …

Data mining framework for random access failure detection in LTE networks

2014

Sleeping cell problem is a particular type of cell degradation. There are various software and hardware reasons that might cause such kind of cell outage. In this study a cell becomes sleeping because of Random Access Channel (RACH) failure. This kind of network problem can appear due to misconfiguration, excessive load or software/firmware problem at the Base Station (BS). In practice such failure might cause network performance degradation, which is hardly traceable by an operator. In this paper we present a data mining based framework for the detection of problematic cells. In its core is the analysis of event sequences reported by a User Equipment (UE) to a serving BS. The choice of N i…

Operator Revenue Analysis for Device-to-Device Communications Overlaying Cellular Network

2018

Device-to-device (D2D) communications has recently gathered significant research interest due to its efficient utilization of already depleting wireless spectrum. In this article, we considered a scenario where D2D users communicate in the presence of cellular users in an overlay network setup. In order to analyze the revenue of service providers in monetary terms, the paper provides exact expressions of operator profit for both D2D and cellular users. More specifically, we take into account different network parameters including user density, transmit power and channel variations to understand their impact on the total revenue of the operator. Finally, we derive the balancing value of freq…

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…

Memorializing mass deaths at the border: two cases from Canberra (Australia) and Lampedusa (Italy)

2017

In this paper, we compare two seemingly very similar instances in which individuals and organizations within the borders of the global North have memorialized the deaths of irregular migrants at sea: the SIEV X memorial in Australia’s national capital Canberra, and the Giardino della memoria (Garden of Remembrance) on the Italian island of Lampedusa. Unlike ephemeral manifestations of grief, potentially these memorials have effects that reach well beyond their creation. We relate the differences between the memorials to the contexts within which they were created: an immediate local response involving people directly affected by the disaster’s aftermath, on the one hand, and a delayed natio…

Changing people’s attitudes and beliefs toward driving through floodwaters : Evaluation of a video infographic

2018

Abstract Despite awareness of campaigns such as ‘Turn Around, Don’t Drown’ and the Australian state of Queensland’s ‘If It’s Flooded, Forget It’, people continue to drive through floodwaters, causing loss of life, risk to rescuers, and damage to vehicles. The aim of this study was to develop a video infographic that highlights the dangers of driving through floodwaters and provide safety tips to reduce the risk, and to evaluate its effectiveness in changing the beliefs and intentions of Australian adults toward this risky driving behaviour. This study adopted an online three-wave non-controlled pretest–posttest design. Australian licensed drivers (N = 201, male = 41, female = 160; Mage = 34…

DEVELOPMENT AND VALIDATION IN A GROUP OF INDUSTRY WORKERS, OF AN APPLICATION FOR AUDIOMETRIC SCREENING: A SOLUTION FOR SOCIAL DISTANCE DURING COVID-1…

2020

In the context of the global COVID-19 pandemic, companies and institutions all over the world are trying to find the best ways to reorganize their activity, minimizing the contagion risk among their employees, so as to protect their health and prevent internal SARS-COV-2 outbreaks. The recent development of new communication technologies, such as smartphones and tablets, has paved the way for the development and implementation of different applications. Starting with the above issues, in this study, we wanted to investigate the efficacy of iAudiometry application developed by our research team for the detection of deficits in the auditory system. Furthermore, we analyzed the precision in de…

Role of odorant-binding proteins in Drosophila melanogaster chemosensory perception

2019

Chemoperception is used by animals to detect nutritive food and avoid toxic compounds. It also allows animals to identify suitable ecological niche and mating partners. Like many other insects, Drosophila melanogaster possesses a very sensitive chemosensory ability and can detect and discriminate a wide panel of semiochemicals. Chemosensory detection is mostly mediated by olfactory and gustatory systems involving several multigene chemoreceptor families. Volatile and non-volatile chemical compounds entering the sensory organ (sensillum) must be solubilized before being transported through the hydrophilic sensillum lymph bathing the dendrites of chemosensory neurons. These perireceptor event…

ANALYSIS OF CORRELATION BETWEEN TAX REVENUES AND OTHER ECONOMIC INDICATORS IN EUROPEAN UNION MEMBER STATES

2014

This paper aims to identify the presence or absence of a connection between some factors that influence the evolution of tax revenue in the EU and to quantify its intensity using Pearson correlation coefficient. Testing the bivariate correlation between tax revenues and a range of 15 causal factors lead to a division of variables that determine the evolution of tax revenues into three categories: significant factors such as GDP, net national income per capita, gross added value, gross salary, current account balance, less significant factors of tax revenue such as the employment rate, public expenditures, public debt, and foreign direct investment, and non-factors of tax revenues such as un…
