Opis:
In this paper, the secure low-power Internet of Things (IoT) transmission methods for encryption and digital signature are presented. The main goal was to develop energyefficient method to provide IoT devices with data confidentiality, integrity, and authenticity. The cryptograph energy efficient and security algorithms modifications for IoT domain were made. The novelty in our solution is the usage of encryption method popular in the image processing in the domain of the Internet of Things. Proposed modification improves immunity for the brute-force and plain-text attacks. Furthermore, we propose the modifications for hash calculation method to transform it into digital signature calculation method that is very sensitive to input parameters. The results indicate low energy consumption of both methods, however it varies significantly depending on the architecture of the devices.

Opis:
Science - research transformation of the Internet of Things (IoT) has a number of colours and shadows, many dimensions including technical, social, community, financial, economic and civilization. This transformation has many wide development roads but also numerable pitfalls and traps. It does not take place solely at the level of scientific and technical progress and innovation. It preliminarily takes place in a complex sociopolitical-economic context, narrowed for simplification as social acceptance and education only. Such acceptance, for example expressed simply by demand and market popularity, for simple items supplemented by useful functions, such as an iron that recognizes the type of fabric and matches its work accordingly, a completely autonomous vacuum cleaner, etc., is trivial. We aim at much deeper relations of IoT with society. If IoT were only adding such functionalities, it would not be worth the time to consider it here. IoT causes a lot of confusion for much more important reasons in many areas of life. Somewhere further on the potential paths of IoT development, it has been noted with interest, but also with anxiety, the possibility of its empowerment as local but also global, superintendent surveillance system, gathering enormous amounts of information, creating knowledge and making autonomous decisions. Potential subjectivity must include such attributes as acquiting from the creator, autonomy, consciousness, morality and further building by the society the whole legal system around the new entity. It will not be a single entity, it will be a whole virtual society, with electronic people. The consequences can be far-reaching and appear as an inevitable option on such a scale for the first time in the history of our human society. Overcoming certain barriers recognized by us may mean that the intelligence and consciousness are not only attributes of the human biological mind. Such reasoning, not without a reason, encounters strong resistance. However, there is a fundamental difference between the opposition to some genetic research and the potential modification of man himself, and the opposition to machine building, a system of superintendence that far exceeds the possibilities of a single man and of entire societies.

Opis:
Blockchain-based cyber-physical systems (CPSs) and the blockchain Internet of things (BIoT) are two major focuses of the modern technological revolution. Currently we have security attacks like distributed denial-of-service (DDoS), address resolution protocol (ARP) spoofing attacks, various phishing and configuration threats, network congestion, etc. on the existing CPS and IoT architectures. This study conducts a complete survey on the flaws of the present centralized IoT system’s peer-to-peer (P2P) communication and the CPS architecture’s machine-to-machine (M2M) communication. Both these architectures could use the inherent consensus algorithms and cryptographic advantages of blockchain technology. To show how blockchain technology can resolve the flaws of the existing CPS and IoT architectures while maintaining confidentiality, integrity, and availability (the CIA triad), we conduct a holistic survey here on this topic and discuss the research focus in the domain of the BIoT. Then we analyse the similarities and dissimilarities of blockchain technology in IoT and CPS architectures. Finally, it is well understood that one should explore whether blockchain technology will give advantages to CPS and IoT applications through a decision support system (DSS) with a relevant mathematical model, so here we provide the DSS with such a model for this purpose.

Opis:
Article focus of the disruptive character of technological innovations brought by Fourth Industrial Revolution (4IR), with its unprecedented scale and scope, and exponential speed of incoming innovations, described from the point view of ‘unintended consequences’ (cross cutting impact of disruptive technologies across many sectors and aspects of human life). With integration of technology innovations emerging in number of fields including advanced robotics, pervasive computing, artificial intelligence, nano- and bio- technologies, additive and smart manufacturing, Forth Industrial Revolution introduce new ways in which technology becomes embedded not only within the society, economy and culture, but also within human body and mind (described by integration of technologies, collectively referred to as cyber-physical systems). At the forefront of digital transformation, based on cyber physical systems, stands Industry 4.0, referring to recent technological advances, where internet and supporting technologies (embedded systems) are serving as framework to integrate physical objects, human actors, intelligent machines, production lines and processes across organizational boundaries to form new kind of intelligent, networked value chain, called smart factory. Article presents broader context of ‘disruptive changes (innovations)’ accompanying 4IR, that embrace both economical perspective of ‘broader restructuring’ of modern economy and society (described in second part of the article as transition from second to third and forth industrial revolution), and technological perspective of computer and informational science with advances in pervasive computing, algorithms and artificial intelligence (described in third part of article with different stages of web development : web 1.0, web 2.0, web 3.0, web 4.0). What’s more important, article presents hardly ever described in literature, psychological and philosophical perspective, more or less subtle reconfiguration made under the influence of these technologies, determining physical (body), psychological (mind) and philosophical aspect of human existence (the very idea of what it means to be the human), fully depicted in the conclusion of the article. The core element (novelty) is the attempt to bring full understanding and acknowledgment of disruptive innovations’, that “change not only of the what and the how things are done, but also the who we are”, moving beyond economical or technological perspective, to embrace also psychological and philosophical one.

Opis:
In recent years, titanium alloys and nickel alloys have become eminent for making aeronautic and astronautic parts. Since both nickel and titanium alloys have a very small thermal conductivity, the being used tool will suffer from huge damage by heat generated during the grinding process. Therefore, there is a requirement for a durable tool with excellent cooling capacity. In this research, the technology regarding the new forced cooling using with high-pressure coolant for machining difficult-to-machine material was developed and evaluated. A through-hole in the near the tip on the rake face of the turning tool is firstly machined by electrical discharge machining. High-pressure coolant was then supplied to the turning tool from the hole on the bottom of the tool. Several values of pressure were tried in many experiments. It is concluded from the results that; (1) a new forced cooling method in the form of drilling a hole at the tip of the tool from which supply high-pressure coolant, a tool temperature decrease and a tool-life prolongation could be achieved, (2) the technology could effectively cool near the tip of turning tool, (3) the chip was effectively broken by the high pressure, (4) It was confirmed that the tool cutting edge condition was stabilized, the surface roughness of the machined workpieces was improved, the tool hardness was maintained and the tool-life was prolonged due to the cooling effect of the devised tool.

Opis:
The main purpose of processing of tough-to-machine materials is improving of cutting process of steels with different physicochemical properties and alloying by means of various chemical elements in combination with heat treatment. Producing of high quality surface layers depends on properties of material used to make details, that is why reasons of tough machining were identified: influence of chemical composition and resulting structure. The studies of grinding of tough-to-machine materials were undertaken by means of grinding wheels made from synthetic diamonds as they are most resistant and highly-productive. Based on the studies recommendations for using of characteristics of grinding wheels and tough-to machine steel grades are given. Research on heat processes during grinding allows us to determine patterns showing how cutting speed, detail motion speed, area and action period of contact influence temperature and speed of heat processes in surface layers as well as depth of heating. These patterns also give the chance to show interrelation between temperature and rate of heating and cooling. This gives an opportunity to predict state of structure of surface layer of details made of tough-to-machine steels under different machining conditions reasonably.

Opis:
The paper covers the theoretical background and tests of two asynchronous squirrel cage generators connected to voltage source inverters working in parallel. Inverters were connected in parallel by their intermediate direct current circuits by means of auctioneering diodes, and then to a DC power network. The real-time control algorithm of digital signal processor DSP and field-programmable gate array FPGA was used to achieve proper excitation of two different power machines, and to maintain high enough levels of direct current link voltage. Windings of both generators are fed by use of so-called machine side inverters. The asynchronous generator is a voltage source inverter controlled by a field-oriented control algorithm based on the current machine model. To prove robustness of the chosen algorithm, different types of load were applied while generators and inverters worked in parallel.
