Efficiency of temporal sensor data compression methods to reduce LoRa-based sensor node energy consumption
2022
Purpose Minimizing the energy consumption in a wireless sensor node is important for lengthening the lifetime of a battery. Radio transmission is the most energy-consuming task in a wireless sensor node, and by compressing the sensor data in the online mode, it is possible to reduce the number of transmission periods. This study aims to demonstrate that temporal compression methods present an effective method for lengthening the lifetime of a battery-powered wireless sensor node. Design/methodology/approach In this study, the energy consumption of LoRa-based sensor node was evaluated and measured. The experiments were conducted with different LoRaWAN data rate parameters, with and without …
Gravity-derived Moho map for Latvia
2020
A precise understanding of crustal structure is essential to the fields of geodynamics, seismology and certain branches of geophysics. A boundary between the crust and the mantle is known as the MohoroviÄiÄ discontinuity, simply referred to as the âMohoâ. Moho geometry and depth have been extensively studied in Europe, but there are still regions with little information about it. One such area is the northern Baltics, Latvia in particular. So far, only one seismic refraction profile, spanning from Sovetsk (Kaliningrad) to Kohtla-Järve (Estonia), has been used to study the deep structure of the Earth in Latvia. We propose gravity inversion (ParkerâOldenburg algorithm) to gain more insight i…
Open-source QCD analysis of nuclear parton distribution functions at NLO and NNLO
2019
We present new sets of nuclear parton distribution functions (nPDFs) at next-to-leading order (NLO) and next-to-next-to-leading order (NNLO). Our analyses are based on deeply inelastic scattering data with charged-lepton and neutrino beams on nuclear targets. In addition, a set of proton baseline PDFs is fitted within the same framework with the same theoretical assumptions. The results of this global QCD analysis are compared to existing nPDF sets and to the fitted cross sections. Also, the uncertainties resulting from the limited constraining power of the included experimental data are presented. The published work is based on an open-source tool, xFitter, which has been modified to be ap…
The BIM (Building Information Modeling)-Based Approach for Road Pavement Maintenance
2019
The recent developments of road pavement survey technologies guarantee acquisition of detailed data regarding the main functional and structural indicators, at a very high frequency and levels of accuracy and precision unconceivable few years ago. The relevant information, regarding surface distresses too, is thus available in economical, high-speed and high-resolution forms, with limited disturbance on traffic and road agencies issues. However, the availability of such a mass of data poses interesting questions concerning the most efficient processing and analysis methods, for optimizing maintenance operation planning. Unfortunately, the PMS adoption is not very common and widespread, as t…
Poverty Permanence Among European Youth
2008
Previous studies suggest that Scandinavian countries are the ones with the highest rates of youth poverty in Europe. This somewhat unexpected finding prompts the question whether the incidence of poverty is an appropriate measure of youth disadvantage. Instead of considering poverty rates we define here youth disadvantage in terms of the number of periods an individual is recorded to be below the poverty line. Using the European Community Household Panel, individuals are classified into different groups of poverty permanence, each reflecting severity of social disadvantage. Based on these categories we implement a generalized ordinal logit model to assess the various factors associated with…
A NEW INDEX OF POVERTY PERSISTENCE
2008
This paper proposes a new indicator of poverty persistence based on a synthesis of the temporal sequences of the years spent in poverty and non poverty, taking into account the order in which poverty spells follow each other. The index is a measure with cardinal properties and it allows not only the ranking of the individuals according to the duration of their poverty experience but also to measure the distance between any two individuals in the population. The index can be built up at individual level and it is also possible to have an aggregated index at any territorial level. Micro data from a longitudinal survey are needed.
Internet e tutela dei dati personali: il consenso ai cookie
2020
The article tackles the issue of protection of personal data of internet users through the usage of cookies by digital content and service providers. It analyses the European legislative framework and, in particular, the General Data Protection Regulation, the so called E-Privacy Directive and the new Directive concerning the supply of digital content and services. The contribution debates the role of individual consent in this field and the interaction with the rules and the remedies provided by European Consumer Law, such as the Unfair Commercial Practices Directive, in order to protect user's personal data in the evolution of data-driven economy.
Datos personales y Cloud Computing
2016
Póster presentado en el XV Workshop de Rebiun "Datos y Bibliotecas", celebrado en Castellón los días 29 y 30 de septiembre de 2016 Las bibliotecas Universitarias están recurriendo con más frecuencia a soluciones informáticas en la nube para seguir ofreciendo el mejor servicio a sus usuarios y, de paso, aprovecharse del ahorro en costes, escalabilidad y mejoras en la gestión de datos que ello supone. Estos servicios en la nube los suelen ofrecer grandes empresas internacionales que han construido complejas y robustas infraestructuras, muchas veces localizadas fuera del territorio de la UE, para ayudar a las bibliotecas a seleccionar, adquirir, procesar, conservar y difundir sus recursos. Per…
Personas datu apstrādes problemātika apdrošināšanā
2018
Bakalaura darbs „Personas datu apstrādes problemātika apdrošināšanā” sniedz ieskatu problēmās, kādas sastopamas apdrošināšanas nozarē personas datu apstrādē laikā, kad spēkā stājas vienots datu apstrādes regulējums visā Eiropas Savienībā. Darba mērķis ir izpētīt Eiropas Padomes regulu par fizisku personu aizsardzību attiecībā uz personas datu apstādi un šādu datu brīvu apriti un ar ko atceļ Direktīvu 95/46/EK, tās piemērošanas īpatnības apdrošināšanā. Darba autors pēta, ar kādam problēmām saskaras apdrošināšanas sabiedrības un apdrošināšanas starpnieki un sniegs iespējamos risinājumus šo problēmu atrisināšanai.
Induction of body weight loss through RNAi-knockdown of APOBEC1 gene expression in transgenic rabbits
2014
In the search of new strategies to fight against obesity, we targeted a gene pathway involved in energy uptake. We have thus investigated the APOB mRNA editing protein (APOBEC1) gene pathway that is involved in fat absorption in the intestine. The APOB gene encodes two proteins, APOB100 and APOB48, via the editing of a single nucleotide in the APOB mRNA by the APOBEC1 enzyme. The APOB48 protein is mandatory for the synthesis of chylomicrons by intestinal cells to transport dietary lipids and cholesterol. We produced transgenic rabbits expressing permanently and ubiquitously a small hairpin RNA targeting the rabbit APOBEC1 mRNA. These rabbits exhibited a moderately but significantly reduced …
