Internet of Things as a Service (iTaaS): challenges and solutions for management of sensor data on the Cloud and the Fog

Building upon cloud, IoT and smart sensors technologies we design and de- velop an IoT as a Service (iTaaS) framework, that transforms a user device (e.g. a smart phone) to an IoT gateway that allows for fast and efficient data streams transmission to the cloud. We develop a two-fold solution, based on micro-services for the IoT (users’ smart devices) and the cloud side (back-end services). iTaaS includes configurations for (a) the IoT side to support data collection from IoT devices to a gateway on a real time basis and, (b) the cloud back-end side to support data sharing, storage and processing. iTaaS provides the technology foreground to enable immediate application deployments in the domain of interest. An obvious and promising implementation of this technology is e-Health and remote health monitoring. As a proof of concept we implement a real time remote patient monitoring system that integrates the proposed frame- work and uses BLE pulse oximeter and heart rate monitoring sensing devices. The experimental analysis shows fast data collection, as (for our experimental setup) data is transmitted from the IoT side (i.e. the gateway) to the cloud in less than 130ms. We also stress the back-end system with high user concurrency (for example with 40 users per second) and high data streams (for example 240 data records per second) and we show that the requests are executed at around 1 second, a number that signifies a satisfactory performance by considering the number of requests, the network latency and the relatively small size of the Virtual Machines implementing services on the cloud (2GB RAM, 1 CPU and 20GB hard disk size)

Management of farms and crops data in the cloud

Technical University of Crete, School of Electrical and Computer Engineering, Diploma ThesisSummarization: Recent technological advances in cloud computing paved the way for developing and offering advanced services for remote monitoring in the agricultural sector. In this thesis, we developed a cloud-based Farm Management Information System, referred as CloudFarm. CloudFarm offers a variety of services that helps farmers to manage and keep control of their farms and crops, by supporting all the basic agricultural activities according to set of Good Agricultural Practices. CloudFarm is accessible to farmers, as a mobile application running on a smart-phone or tablet that connects with the cloud, and as a Web application running in the cloud. The “on the go” system means that farmers can manage and capture scheduled or performed activities directly from fields, while using a mobile application. Mobile application is synchronized with information stored permanently in the cloud so that farmers can have always access to up-date information. Furthermore, CloudFarm offers a Web application where farmers can monitor their data and certified advisors can monitor the farmers’ agricultural activities and advise them about their farm status and best planning of farm and crops works

Synthesis and evaluation of condensed magnetic nanocrystal clusters with<em> in&nbsp;vivo </em>multispectral optoacoustic tomography for tumour targeting.

Colloidal clusters of magnetic iron oxide nanocrystals (MIONs), particularly in the condensed pattern (co-CNCs), have emerged as new superstructures to improve further the performance of MIONs in applications pertaining to magnetic manipulation (drug delivery) and magnetic resonance imaging (MRI). Exploitation of the advantages they represent and their establishment in the area of nanomedicine demands a particular set of assets. The present work describes the development and evaluation of MION-based co-CNCs featuring for the first time such assets: High magnetization, as well as magnetic content and moment, high relaxivities (r2&nbsp;=&nbsp;400 and [Formula: see text] ) and intrinsic loss power (2.3&nbsp;nH&nbsp;m(2) kgFe(-1)) are combined with unprecedented colloidal stability and structural integrity, stealth and drug-loading properties. The reported nanoconstructs are endowed with additional important features such as cost-effective synthesis and storage, prolonged self-life and biocompatibility. It is finally showcased with in&nbsp;vivo multispectral optoacoustic tomography how these properties culminate in a system suitable for targeting breast cancer and for forceful in&nbsp;vivo manipulation with low magnetic field gradients

CloudFarm: management of farms and crops data on the cloud

Summarization: Recent technological advances in Cloud Computing technology paved the way for developing and offering advanced services for remote monitoring in many industry areas; including the agricultural sector. In this work, we developed a Cloud-based farm management information system, referred as CloudFarm. CloudFarm offers a variety of services that helps farmers to manage and keep control of their farms and crops, by supporting all the basic agricultural activities according to set of good agricultural practices. CloudFarm is accessible to farmers, as a mobile application running on a smartphone or tablet that connects with a Cloud service for data analysis and orchestration. The 'on the go' system means that farmers can manage and capture scheduled or performed activities directly from fields, while using the smartphone application that is synchronized with data stored permanently on the cloud so that farmers can have always access to up-date and real-time information. Furthermore, CloudFarm offers a Web application where farmers can monitor their data and certified advisors can monitor the farmers' agricultural activities and advise the m about their farm status and best planning of farm and crops works.Παρουσιάστηκε στο: 32nd IEEE International Conference on Advanced Information Networking and Application
