Joint Radio and Computational Resource Allocation in IoT Fog Computing
2018
The current cloud-based Internet-of-Things (IoT) model has revealed great potential in offering storage and computing services to the IoT users. Fog computing, as an emerging paradigm to complement the cloud computing platform, has been proposed to extend the IoT role to the edge of the network. With fog computing, service providers can exchange the control signals with the users for specific task requirements, and offload users’ delay-sensitive tasks directly to the widely distributed fog nodes at the network edge, and thus improving user experience. So far, most existing works have focused on either the radio or computational resource allocation in the fog computing. In this work, we inve…

SMCP: a Secure Mobile Crowdsensing Protocol for fog-based applications
2020
Abstract The possibility of performing complex data analysis through sets of cooperating personal smart devices has recently encouraged the definition of new distributed computing paradigms. The general idea behind these approaches is to move early analysis towards the edge of the network, while relying on other intermediate (fog) or remote (cloud) devices for computations of increasing complexity. Unfortunately, because both of their distributed nature and high degree of modularity, edge-fog-cloud computing systems are particularly prone to cyber security attacks that can be performed against every element of the infrastructure. In order to address this issue, in this paper we present SMCP…

Mobile phone and auditory system: update
2009
The aim of this study is to asses the non-thermal effects of the electromagnetic fields generated by 915 MHz GSM cellular phones on the human cochlear activity using transient evoked otoacoustic emissions (TEOAE). The study was carried on 205 young and healthy volunteers (age 18-30 years) with normal hearing which were randomly divided into two samples consisting of 85 (Gcase) and 120 (Gcontrol) respectively. The first one was exposed to genuine 10 minutes of GSM electromagnetic fields while the second, undergone sham exposure, was considered as control group for the statistical investigations. All the participants were blind to the genuine or sham exposure. The TEOAEs were measured in the …
Detection of a reservoir water level using shape similarity metrics
2017
The matching between reservoirs’ water edge and digital elevation model’s (DEM) contour lines allowed determining the water level at the acquisition date of satellite images. A preliminary study was conducted on the Castello dam (Magazzolo Lake), between Alessandria della Rocca and Bivona (Agrigento, south-Italy). The accuracy assessment of the technique was than evaluated from the comparison between classified and reference objects using similarity metrics about the shape, theme, edge and position, through the plugin STEP of open source software GIS. Moreover, an independent GIS technique was implemented to evaluate the water level, based on a distances’ array between existing contour line…
Politiskās sistēmas ietekme uz Singapūras izaugsmi
2018
Darbā tiek pētīta Singapūras ekonomiskās izaugsmes iemesli, fokusu liekot uz valdības ieturētajām politikām, kopš valsts neatkarības pasludināšanas 1965. gadā. Par pamatu analīzei tiek izvirzīts jautājums – Vai autoritārais režīms bija galvenais iemesls tam, ka Singapūra bija spējīga pieņemt lēmumus par labu liberālajai ekonomikai? Par teorētisko pamatu darbam kalpo konkurences autoritārisma, modernizācijas, liberālās ekonomikas teorijas. Analīzes nolūkos tiek izvirzīti trīs galvenie sektori, kuru lēmumi tiek aplūkoti caur izvirzīto teoriju – investīciju, īpašumu un izglītības sektors. Pētījums gaitā tiek skatīti galvenie lēmumi, kuri pieņemti trijos izpētes sektoros cenšoties padarīt Singa…
Living on a knife’s edge: Temporal conflicts in welfare service work
2012
This article considers the temporal variations of agency from the point of view of social and health care workers’ experiences and the social structures and practices of the contemporary public service sector. It is based on an interview study of 24 Finnish welfare service workers. The results show that the public service sector increasingly operates according to market principles and an economic-rationalistic framing of time, contrary to the relational understanding of time in care practices. To maintain their sense of self as skilled professionals, workers actively reassess and adjust their identities according to the exigencies of working life, but not without difficulties. The results …
5G IoT System for Real-Time Psycho-Acoustic Soundscape Monitoring in Smart Cities With Dynamic Computational Offloading to the Edge
2021
Environmental noise monitoring for smart cities need to be as much efficient as possible in order to mitigate its significant impact in the health of their inhabitants. 5G Internet of Things (IoT) systems offer a big opportunity to offload the computation from the sensor nodes, since it provides a series of new concepts for dynamic computing that the previous technologies did not offer. In this article, a complete 5G IoT system for psycho-acoustic monitoring has been designed and implemented using different options for offloading computation to different parts of the system. This offloading has been done by developing different functional splittings of the psycho-acoustic metrics algorithms…
Starptautiskā migrācija kā faktors sociāli ekonomiskās izaugsmes nodrošināšanai Latvijā
2018
Maģistra darbs "Starptautiskā migrācija kā faktors sociāli ekonomiskās izaugsmes nodrošināšanai Latvijā" sniedz ieskatu par starptautiskās migrācijas ietekmi uz sociāli ekonomisko attīstību Latvijā, kā arī noskaidro vai Latvijas valdība plāno risināt demogrāfiskās problēmas veicinot imigrāciju. Attiecīgi darba gaitā tiek pētītas iedzīvotāju novecošanas tendences Baltijas Jūras valstīs, kā arī pētīti sabiedrības un valdības viedokļi par sociāli ekonomisko un demogrāfisko aspektu izaugsmi Latvijā. Rezultāti liecina, ka ne valdība, ne sabiedrība neuzskata, ka zemas kvalifikācijas darbaspēka pieplūdums veicinātu Latvijā dzīvojošo labklājību. Tas liecina, ka tuvākajā nākotnē sociāli ekonomiskā i…
