The purpose of this paper is to present fully automated systems that monitors on a real time basis the non-ionizing electromagnetic radiation emitted by wireless networks. The presented radio monitoring systems aim to perform repetitive and reliable measurements by using a well-defined measurement algorithm as well as high quality calibrated equipment and to inform the public - using the widespread web technologies - about the levels of the electromagnetic radiation emitted by any wireless telecommunication system.

Monitoring systems are needed to obtain information about particulate matter (PM) concentrations and to make such information accessible to the public. Small, low-cost, optical sensors could be used to improve the spatial and temporal resolution of PM data. The paper presents results of collocated comparison of four low-cost PM sensors and TEOM analyser, conducted from 20-08-2017 to 24-12-2017 in Wrocław, Poland. Plantower PMS7003 and Nova Fitness SDS011 sensors proved to be the best in terms of precision and were linearly correlated with TEOM data. Alphasense OPC-N2 sensors exhibited only moderate precision and linearity. Winsen ZH03A sensors had low repeatability between units and only one copy demonstrated good operation possibilities. All tested sensors had a bias in relation to PM2.5 concentrations obtained from TEOM.

COVID-19 is a global pandemic infecting human life. There are many patients who have recovered from this deadly virus and need to be monitored constantly even when they are at home. IoT plays a vital role in health systems that help to monitor patient’s health conditions. These healthcare frameworks consist of smart sensors to keep a track of patient’s vitals on a real-time basis. These systems will help bridge gaps between the patients and doctors during the pandemic situation. In order to make our system competitive against the already existing devices, we prepared a comprehensive review where we extensively studied other products and compared them to find what's best for the patients.

The Past

Historical data pose a variety of problems to those who seek statistically based understandings of the past. Quantitative historical analysis has been limited by researcher’s reliance on rigid statistics collected by individuals or agencies, or else by researcher access to small samples of raw data. Even digital technologies by themselves have not been enough to overcome the challenges of working with manuscript sources and aligning dis-aggregated data. However, by coupling the facilities enabled by the web with the enthusiasm of the public for explorations of the past, history has started to make the same strides towards big data evident in other fields. While the use of citizens to crowdsource research data was first pioneered within the sciences, a number of projects have similarly begun to draw on the help of citizen historians. This article explores the particular example of the Prosecution Project, which since 2014 has been using crowdsourced volunteers on a research collaboration to build a large-scale relational database of criminal prosecutions throughout Australia from the early 1800s to 1960s. The article outlines the opportunities and challenges faced by projects seeking to use web technologies to access, store and re-use historical data in an environment that increasingly enables creative collaborations between researchers and other users of social and historical data.

Over the past several decades the demand for accountability in the field of public administration has been growing exponentially in Europe. The particular emphasis for this theme was the stimulus for the significant adoption and use of information technology systems in the public sector. Thus, the main focus of European countries has been e-government that provides process reform of the manner in which governments work, share information, and deliver services to external and internal clients. Therefore, accountability has become more critical for improving the economic, financial and organizational management of public matters. The need for accountability has pushed the Italian legislature to produce a sequence of legislative and regulatory interventions towards increased transparency in public administrations. This paper presents an account of the likely consequences that performance monitoring systems have, through e-government technology, on public service transparency and accountability. This research utilizes a study on the Brunetta reform (from the Ministry of Public Administration) to foster public sector productivity; that study's key principles are efficiency, meritocracy, accountability, and transparency.

Federated Identity

In recent research, two approaches to protect SAML based Federated Identity Management (FIM) against man-in-the-middle attacks have been proposed. One approach is to bind the SAML assertion and the SAML artifact to the public key contained in a TLS client certificate. Another approach is to strengthen the Same Origin Policy of the browser by taking into account the security guarantees TLS gives. This work presents a third approach which is of further interest beyond IDM protocols, especially for mobile devices relying heavily on the security offered by web technologies. By binding the SAML assertion to cryptographically derived values of the TLS session that has been agreed upon between client and the service provider, this approach provides anonymity of the (mobile) browser while allowing Relying Party and Identity Provider to detect the presence of a man-in-the-middle attack.

Today’s health standards demand a high quality and efficiency as a major characteristic of every health service provided to the public, even in cases where patients have to be treated from a distance. The combination of medicine and information technology (telecommunications) led to the introduction of the term telemedicine. Telemedicine services are used in assisting remote patients. Interaction and feedback through patient monitoring systems and devices allow the health providers interfere when necessary, so medical maintenance can be guaranteed. This chapter deals with the different kinds of such systems and devices. The contribution of old and new telecommunication technologies is currently being discussed. The individual needs of every remote patient are taken into account, thus, several devices and systems are used for telemonitoring. This chapter indicates characteristics and features of the various kinds of patient monitoring systems and devices.

Radiating Element

Ommidirectional in azimuth plane antennas with horizontal polarization are used in communication systems of McWILL standard, digital television systems of DVB-T2 standard, radio monitoring systems, semi-active ranging using the target illumination with the television broadcast signal, and many other cases. In many cases, radar and radio monitoring systems use phase methods to determine the azimuth and elevation angle of the target. To view all azimuthal angles, ring arrays consisting of omnidirectional emitters, usually also represented by ring arrays, are used. This paper studies the characteristics of an omnidirectional radiating element of electrically small horizontal dipole elements. An expression is derived that relates the radius of the dipole ring array to the number of dipoles and the variation of the resulting radiation pattern. The results are confirmed by experimental studies.
