Usability and acceptability of a fall monitoring system

2017

Falls and injurious falls affect one third of the older people. Those experiencing a fall might be unable to call for help remaining unattended for a long time. Pain, hypothermia and dehydration are common consequences. Additionally, ensuing fear of falling may reduce physical activity leading to functional decline and possibly institutionalization. Monitoring fall events the CONFIDENCE system could summon emergency assistance automatically thus reducing the negative consequences of falls. This thesis is part of the European FP7 project “Ubiquitous care system to support independent living” (CONFIDENCE) which developed a fall monitoring system based on three-dimensional (3D) localization of…

Len’ka Panteleev and the traditions of Van’ka Kain: Criminal Biography in XXth Century Russia

2017

The Fighter against the myth, or the memoirist who considers himself a Hercules (Anton Pavlovich Chekhov: an attempt at a characterization by N.M. Ezhov). The vast corpus about the 1920s Petrograd bandit Len’ka Panteleev, comprised of different texts – such as newspaper articles, fiction, film and song, with a complex and often ambiguous interplay between factual accounts and fictional adaptation – seems untypical for the era. A useful term of comparison is the similar corpus concerning the 18th century Moscow rogue Van’ka Kain. The latter shows all the typical features of 18th century criminal biographies, which at the time were popular throughout Europe. According to Michel Foucault, this…

Digitāla vizuālo spēju testēšanas rīka izstrāde un eksperimentāla analīze klīnisku un ikdienas populāciju gadījumā

2022

Mūsdienās neirodeģeneratīvo slimību ārstēšanas ir efektīva tad, ja slimības pazīmes tika atrastas agrīnā stadijā. Bakalaura darba ietvaros autors izstrādā kognitīvo traucējumu noteikšanas rīku, kas varētu palīdzēt cilvēkiem ātrāk identificēt simptomus. Darbā tika paveikts literatūras pārskats, kursa darba izstrādāta digitāla mentālas rotācijas prototipa apraksts, analīze un pilnveidošana līdz minimāla darbspējīga produkta stāvoklim. Tiek detalizēti aprakstīts kognitīvo traucējumu noteikšanas rīka izstrādes process, darba organizācija, pielietotas tehnoloģijas, plānošana, lietotnes palaišana un testēšana. Rīka testēšana piedalījās vairāk par 50 cilvēkiem, kuri pirmajā posmā pārbaudīja trīs d…

First operational experience of HIE-ISOLDE

2016

The High Intensity and Energy ISOLDE project (HIE-ISOLDE)* is a major upgrade of the ISOLDE facility at CERN. The energy range of the post-accelerator will be extended from 2.85 MeV/u to 9.3 MeV/u for beams with A/q = 4.5 (and to 14.3 MeV/u for A/q = 2.5) once all the cryomodules of the superconducting accelerator are in place. The project has been divided into different phases, the first of which (phase 1a) finished in October 2015 after the hardware and beam commissioning were completed**. The physics campaign followed with the delivery of both radioactive and stable beams to two different experimental stations. The characteristics of the beams (energies, intensities, time structure and b…

Anomaly detection in wireless sensor networks

2016

Wireless Sensor Network can be defined as a network of integrated sensors responsible for environmental sensing, data processing and communication with other sensors and the base station while consuming low power. Today, WSNs are being used in almost every part of life. The cost effective nature of WSNs is beneficial for environmental monitoring, production facilities and security monitoring. At the same time WSNs are vulnerable to security breaches, attacks and information leakage. Anomaly detection techniques are used to detect such activities over the network that do not conform to the normal behavior of the network communication. Supervised Machine learning approach is one way to detect…

Large Azobenzene Macrocycles : Formation and Detection by NMR and MS Methods

2023

Azobenzene macrocycles are widely investigated as potential drug delivery systems and as part of molecular machines due to their photo-responsive properties. Herein, we detect the formation of a series of new azobenzene macrocycles that feature up to eight switchable repeating units. High-resolution mass spectrometry and ion mobility (IM) mass spectrometry experiments and 1H and diffusion-ordered spectroscopy (DOSY) NMR are used to detect the presence of the macrocycles that contain 10 to 40 aromatic rings in the gas phase and solution, respectively. The responsiveness of the Z-to-E photo-switching of the smallest of the macrocycles, exhibiting two azobenzene units and in total 10 aromatic …

Laser assisted decay spectroscopy at the CRIS beam line at ISOLDE

2012

A new collinear resonant ionization spectroscopy (Cris)beam line has recently been installed at Isolde, Cern utilising lasers to combine collinear laser spectroscopy and resonant ionization spectroscopy. The combined technique offers the ability to purify an ion beam that is heavily contaminated with radioactive isobars, including the ground state of an isotope from its isomer, allowing sensitive secondary experiments to be performed. A new programme aiming to use the Cris technique for the separation of nuclear isomeric states for decay spectroscopy will commence in 2011. A decay spectroscopy station, consisting of a rotating wheel implantation system for alpha decay spectroscopy, and thre…

Lasīšanas Detektīvi Skolēnu Lasītprasmes (Lasītpratības) Pilnveidei Angļu valodas stundās 7.klasē

2020

Diplomdarba autores pieredze liecina, ka salīdzinoši neliels pētījumu skaits Latvijā veikts saistībā ar skolēnu lasītpratības mērījumiem svešvalodā. No otras puses, līdzīgi pētījumi ik gadu tiek veikti un ir zināmi kā starptautiskie lasītprasmes novērtēšanas pētījumi (PIRLS), kur tiek noteiktas lasīšanas spējas sākumskolas skolēniem. Taču oficiālu datu par kopējo lasītprasmes līmeni pusaudžiem, lasot svešvalodā, ir nepietiekami. Tā kā svešvalodas apguve ir saistīta ar dzimtās valodas izpratni, tiek uzsvērta metakognitīvā pieeja un kā viena no metakognitīvām stratēģijām minēti ir lasīšanas detektīvi. To fokuss ir kognitīvās stratēģijas, kas parādās skolēnam sastopoties ar izaicinošu tekstu. …

HYPERSPECTRAL REFLECTANCE SIGNATURES AND POINT CLOUDS FOR PRECISION AGRICULTURE BY LIGHT WEIGHT UAV IMAGING SYSTEM

2018

Abstract. The objective of this investigation was to study the use of a new type of a low-weight unmanned aerial vehicle (UAV) imaging system in the precision agriculture. The system consists of a novel Fabry-Perot interferometer based hyperspectral camera and a high-resolution small-format consumer camera. The sensors provide stereoscopic imagery in a 2D frame-format and they both weigh less than 500 g. A processing chain was developed for the production of high density point clouds and hyperspectral reflectance image mosaics (reflectance signatures), which are used as inputs in the agricultural application. We demonstrate the use of this new technology in the biomass estimation process, w…
