Medical Data Processing and Analysis for Remote Health and Activities Monitoring
2019
Recent developments in sensor technology, wearable computing, Internet of Things (IoT), and wireless communication have given rise to research in ubiquitous healthcare and remote monitoring of human’s health and activities. Health monitoring systems involve processing and analysis of data retrieved from smartphones, smart watches, smart bracelets, as well as various sensors and wearable devices. Such systems enable continuous monitoring of patients psychological and health conditions by sensing and transmitting measurements such as heart rate, electrocardiogram, body temperature, respiratory rate, chest sounds, or blood pressure. Pervasive healthcare, as a relevant application domain in thi…

2018
Darba mērķis ir izstrādāt lietu interneta platformas arhitektūru, kura nodrošina daudzlietotāju atbalstu, ir viegli uzstādāma no galalietotāju skatupunkta, un kuru ir iespējams piedāvāt potenciāliem lietotājiem kā pakalpojumu, parūpējoties par tās uzstādīšanu un uzturēšanu. Darba gaitā ir veikts OpenHAB un Home Assistant lietu interneta platformu funkcionalitāšu apskats, salīdzinājums un to piemērotības izvērtējums daudzlietotāju arhitektūras izveidošanai. Darba rezultātā ir izveidots Home Assistant platformas arhitektūras risinājums, kurš ļauj veikt vienkāršu sākotnējo platformas uzstādīšanu, nodrošina daudzlietotāju atbalstu, izmantojot vairākas platformas instances vienā resursdatorā, un…
A Digital Twin predictive maintenance framework of air handling units based on automatic fault detection and diagnostics
2022
The building industry consumes the most energy globally, making it a priority in energy efficiency initiatives. Heating, ventilation, and air conditioning (HVAC) systems create the heart of buildings. Stable air handling unit (AHU) functioning is vital to ensuring high efficiency and extending the life of HVAC systems. This research proposes a Digital Twin predictive maintenance framework of AHU to overcome the limitations of facility maintenance management (FMM) systems now in use in buildings. Digital Twin technology, which is still at an initial stage in the facility management industry, use Building Information Modeling (BIM), Internet of things (IoT) and semantic technologies to create…
The play and language behavior of mothers with and without dyslexia and its association to their toddlers' language development.
2004
The play and language behavior of mothers with ( n = 49) and without ( n = 49) specific reading disabilities (RD) was investigated during play with their 14-month-old children. The contribution of maternal behavior to the language development of their children was examined. The children's receptive and expressive language skills were assessed longitudinally at 14, 18, and 30 months, using the MacArthur Communicative Development Inventories and the Reynell Developmental Language Scales. Children with and without familial risk for RD did not differ from each other in any play or language measures at these ages. No group differences were found for mothers' manifestations of nonsymbolic play a…
Compression Methods for Microclimate Data Based on Linear Approximation of Sensor Data
2019
Edge computing is currently one of the main research topics in the field of Internet of Things. Edge computing requires lightweight and computationally simple algorithms for sensor data analytics. Sensing edge devices are often battery powered and have a wireless connection. In designing edge devices the energy efficiency needs to be taken into account. Pre-processing the data locally in the edge device reduces the amount of data and thus decreases the energy consumption of wireless data transmission. Sensor data compression algorithms presented in this paper are mainly based on data linearity. Microclimate data is near linear in short time window and thus simple linear approximation based …
Optimization on ports activation towards energy efficient data center networks
2018
Nowadays, Internet of thing including network support (i.e. checking social media, sending emails, video conferencing) requires smart and efficient data centers to support these services. Hence, data centers become more important and must be able to respond to ever changing service requirements and application demands. However, data centers are classified as one of the largest consumers of energy in the world. Existing topologies such as ScalNet improves the data center scalability while leading to enormous amounts of energy consumption. In this paper, we present a new energy efficient algorithm for ScalNet called Green ScalNet. The proposed topology strikes a compromise between maximizing …
Defining an Internet-of-Things Ecosystem
2012
By bringing the Internet connectivity to the things, the Internet-of-Things (IoT) promises a number of benefits to its customers, varying from faster and more accurate sensing of our environment, to more cost-efficient tracking of industrial processes. Likewise, from the business perspective, the wide adoption of IoT is expected to generate significant revenues to the providers of IoT application and services. The IoT adoption depends on whether the ecosystems of the companies focusing on IoT technologies would emerge and succeed in delivering to the market the solutions attractive to the customers. Therefore, it is of utmost importance to understand the essence and constituents of IoT ecos…
Into the world of e-waste: mobility among e-scrappers in Nigeria
2017
AbstractIn the management of e-waste, mobility of e-scrappers plays a pivotal role, especially in e-waste acquisition and sales of extracted materials. This research examines the relationship between e-scrappers and the locations of their work by analysing the influence of environmental and social factors on their mobility behaviour in Nigeria. A qualitative analysis of video material collected from 29 male e-scrappers in Nigeria between 2014 and 2015 reveals that e-waste has inherent properties that intermittently mobilise e-scrappers to search for recyclable and valuable electronic trash. Applying the new mobilities paradigm and the new materialism theory, we present that e-scrappers’ mob…

L’etichettatura di sostenibilità nel settore vitivinicolo
2022
Nel settore vitivinicolo la sostenibilità e la sua comunicazione al consumatore per mezzo dell’etichettatura, nel rispetto della normativa in materia, ha assunto una crescente rilevanza, anche in ragione delle pressanti esigenze ambientali e climatiche che costringono ad un ripensamento in chiave digitale di sistemi e tecniche di produzione, in un’ottica di ottimizzazione e preservazione delle risorse naturali. Partendo da una preliminare riflessione circa il significato giuridico del termine “sostenibile”, il contributo si sofferma su come il legame tra iniziativa imprenditoriale, sviluppo di innovative tecnologie digitali, ricerca di nuovi spazi di mercato e sicurezza giuridica abbia anc…
