Current tendencies in electronics and informatics development going towards Internet of Things (IoT), Big Data or Data Cloud technologies create new possibilities in acquiring and utilizing data. The article presents the concept of modular monitoring of vehicles operating parameters. Presented device registers data from the OBD system and a set of independent, configurable sensor modules. Data from the OBD system is acquired via protocol. CAN Bus with a DLC connector. The signal from sensor modules is transferred via a Bluetooth wireless network. The registered data can be storage on board as CD card memory or alternatively on a typical user interface such as laptop, tablet, cell phone etc. The communication with the user interface is realised with USB. Moving vehicles modular monitoring system presented in the article can be used to attain a fuller representation of the vehicles state in relation to its environment. The base assumption of the device is maximal flexibility in term of sensors versality as well as possibilities of assembly on board. In connection with the concept, a prototype of the device was made and tested with an inertial measurement unit (IMU) module and a pressure sensor. Appliances modules are based on Cortex M4 and M0 processing units. A users interface in LabVIEW and examples of registered signals are showed at the end of the article.
Development of IoT is tightly coupled with the use of the wireless communication solutions. Nowadays there are several standard wireless protocols, which are responsible for carrying information. The increase of the communication traffic tends to specialize the kind of used data interchange methods for the sake of demanded size of data packet, frequency of connections, meaning of the data, security and safety of the transmission as well as many others. One of the intensively spreading wireless networks is LoRaWAN. Because of its low energy consumption, long distance range, and high flexibility, it seems to be very effective solution to apply in the field of road traffic. The article presented the base features of LoRaWAN as well as the conception of virtual local traffic system based on the data yield from the board systems of cars. Accessed from OBD information about f. e.g. temporary cars speed or accelerations associated with their current position can be significant factor in creating the real image of the traffic situation.

Whether there is a difference between different levels of plasma ferritin between two methods and whether these methods could be used interchangeably have also been evaluated. The first result of the study regarding whether there is a difference among plasma ferritin levels according to the methods have revealed that the difference was statistically significant. Secondly, the results of the two methods were in
This paper investigates the local and global forces acting on the coil structure of a low-speed modular permanent magnet generator for wind energy application. Two different configurations of the coil structure are studied. The first one consists of separately replaceable single-coil modules, whereas the second consists of three-phase coil-module assemblies. The purpose of the analysis is to investigate the advantages and disadvantages of each configuration in terms of vibrations and mechanical robustness. The investigations also provide the load for the mechanical analysis needed in the design of the retaining structure of the generator. The results show that there are strong fluctuations in the radial forces acting on the single-coil structure. The three-phase coil-module assembly reduces the fluctuations of the radial forces, but it results in an increase of the cogging torque, which is not suitable for the slotless design. Namely, the advantage of the slotless design is to reduce the cogging torque. The computed forces are then used in a structural mechanical simulation, the results of which are validated through strain measurements. The validation procedure is carried out on a specially built mock-up as accessing the generator on site is not possible.
The project deals with design and implementation of adjustment onto mounting tables in the automotive industry. Manual control system of the jigs is replaced by a pneumatic system. Advantages of the pneumatic system are eliminating service side-time, improving work flow and increasing safety and ergonomics at work. Thanks to higher effectivity of the work process, manpower can be used in other work positions.
This paper describes a model of modular system for Rapid Application Development of Web-based Information Systems (RADWIS). The existing modular systems on technology, framework and platform level does not fully solve the problems of functionality reuse, rapid application development and balance between the complexity, size and functionality. The proposed modular system addresses these problems in a new way. The current work fills the gap between the modular systems on the framework and platform level. The model uses flexible, reusable modules, which can be built with different technologies. They are installable and shareable with the standard dependency manager of the technology and can communicate using web services. The modules use NoSQL approaches in SQL databases. A workflow engine module, based on the Petri Nets theory, allows a graphical and formal mathematical solution for a wide variety of problems.
This paper seeks to present organisational and programme assumptions of a new field of postgraduate studies called Cultural industries in the development policies of cities and regions, prepared by a team of workers of the Institute of Socio-Economic Geography and Spatial Management of Adam Mickiewicz University in Poznań as a didactic innovation based on a modular system of education that meets contemporary changes in the labour market. The analysis will also embrace experiences following from the educational process implemented under the Human Capital Operational Programme in the years 2013–2015 (Priority IV: Tertiary Education and Science, Measure 4.3: Enhancing the didactic potential of universities in areas of key importance for the Europe 2020 Strategy). They provide a basis for conclusions and recommendations for higher schools interested in the development of this area of education.
Motivated by the effectiveness of correlation attacks against Tor, the censorship arms race, and observations of malicious relays in Tor, we propose that Tor users capture their trust in network elements using probability distributions over the sets of elements observed by network adversaries. We present a modular system that allows users to efficiently and conveniently create such distributions and use them to improve their security. To illustrate this system, we present two novel types of adversaries. First, we study a powerful, pervasive adversary that can compromise an unknown number of Autonomous System organizations, Internet Exchange Point organizations, and Tor relay families. Second, we initiate the study of how an adversary might use Mutual Legal Assistance Treaties (MLATs) to enact surveillance. As part of this, we identify submarine cables as a potential subject of trust and incorporate data about these into our MLAT analysis by using them as a proxy for adversary power. Finally, we present preliminary experimental results that show the potential for our trust framework to be used by Tor clients and services to improve security.
The paper provide an insight into the research conducted by the University of Ljubljana, and the Urban institute of Slovenia committed to the assessment of the efficiency related to the management of local resources at the level of neighbourhoods. The reduction of energy consumption and energy efficient built environments are key objectives of many sustainability agendas which is followed by suitable assessment methods in urban analytics. However, there are two important hesitations occurring: first, traditional assessment methods that focus solely on the energy reduction and efficiency are often too narrow in their analysis and limited in their scope of impact. According to the recent advances in research worldwide, efforts solely related to reduction of energy consumption will unlikely lead to more responsive environments or rise the living quality. Thus, more comprehensive methodologies for assessing and monitoring the change and transformation in built environments shall be sought for to reach long-term sustainability. Second, to date, the majority of the evaluation methods - whether focusing to energy consumption or broader sustainability issues - are building- or household- oriented, thus systematically examining separate spatial and social entities, but neglecting the spaces between, the holistic aspect and the community aspect. The research develops structured evaluation model, where two main research pillars are addressed: 1) the development of the structured and modular system of indicators; and 2) the development of the methodology to interpret the resulting values. The paper presents first two stages of the research process and subjects the outcomes to the debate.
