The paper describes modification of the ATA (Attack Tree Analysis) technique for assessment of instrumentation and control systems (ICS) dependability (reliability, availability and cyber security) called AvTA (Availability Tree Analysis). The techniques FMEA, FMECA and IMECA applied to carry out preliminary semi-formal and criticality oriented analysis before AvTA based assessment are described. AvTA models combine reliability and cyber security subtrees considering probabilities of ICS recovery in case of hardware (physical) and software (design) failures and attacks on components casing failures. Successful recovery events (SREs) avoid corresponding failures in tree using OR gates if probabilities of SRE for assumed time are more than required. Case for dependability AvTA based assessment (model, availability function and technology of decision-making for choice of component and system parameters) for smart building ICS (Building Automation Systems, BAS) is discussed.

The high irradiance in tropical area is certainly favorable to photovoltaic (PV) power output, since the efficiency depends on the solar radiation intensity. However the increase of cells temperature causes conversely a fall of the yield of the modules. This decrease in the performance of PV modules due to temperature effect also causes proportional voltage decrease. This drop in performance is at the expense of destabilisation of the electrical network and if the electrical power output of modules is planned for a total grid injection. A time series may be useful in forecasting another time series and this statistical hypothesis test is called the Granger causality test. In this paper, we show that the Granger causality can be applied to PV parameters time series and an error correction model is used to determine a long term relationship of power output for PV systems.

In the last few years image processing and analysis, particularly, video and image compression became very important due to immense development of new multi-media products, surveillance systems, automotive industry, etc, and the shortage of bandwidth and storage space of the memory. In the paper we consider a mathematical model as an approach to image processing, compression and restoration. We use edge detection algorithm to construct infinite system of difference equations, which is encoded by means of given family of functions, i.e. low degree polynomials, piece-wise linear functions or Heaviside step functions. Corresponding encoding and decoding algorithm is proposed, along with comprehensive theoretical background. The existence and uniqueness of decoded image is considered. This paper presents some preliminary study of the advantages and drawbacks of the approach and indicates areas of possible further research.

With the surge in global data consumption with proliferation of Internet of Things (IoT), remote monitoring and control is increasingly becoming popular with a wide range of applications from emergency response in remote regions to monitoring of environmental parameters. Mesh networks are being employed to alleviate a number of issues associated with single-hop communication such as low area coverage, reliability, range and high energy consumption. Low-power Wireless Personal Area Networks (LoWPANs) are being used to help realize and permeate the applicability of IoT. In this paper, we present the design and test of IEEE 802.15.4-compliant smart IoT nodes with multi-hop routing. We first discuss the features of the software stack and design choices in hardware that resulted in high RF output power and then present field test results of different baseline network topologies in both rural and urban settings to demonstrate the deployability and scalability of our solution.

When designing and installing Indoor Positioning Systems, several interrelated tasks have to be solved to find an optimum placement of the Access Points. For this purpose, a mathematical model for a predefined number of access points indoors is presented. Two iterative algorithms for the minimization of localization error of a mobile object are described. Both algorithms use local search technique and signal level probabilities. Previously registered signal strengths maps were used in computer simulation.

The Arctic is a very promising region for hydrocarbon production. At the same time, this region is very severe in terms of climate. Low temperatures and high humidity complicate metals welding in the Arctic. These conditions require the protection of the welding zone for high-quality welding. The authors propose to use gas-shielded welding. The authors studied the effect of conditions of gas flow from the nozzle on the characteristics of the jet when gas welding in the Arctic. It was found that the gas flow from the nozzle is effected by the shape and aerodynamic quality of the nozzle flow passage; the type and thickness of the boundary layer on the inner side of the nozzle; the degree of flow turbulence at the nozzle outlet; variation of the velocity at the nozzle outlet; the ratio of the density of the gas jet and surrounding air.

The detection/recognition of trees (trunks and branches) from 2D images is a challenging task in image processing. The large variety of visual appearance, environmental conditions, and occlusion make it an ill-posed problem. In our work we overview different approaches to solve this problem including the performance analysis of a pixel-level clustering and a neural network based approach. Besides discussing low-level approaches we proceed from low-level (pixel-level) representations to a high-level model using graphs. Thus the problem is transformed to fitting graph structures (vertices and edges) to 2D images based on appearance, and on prior information about trees. We use Reversible Jump Markov Chain Monte Carlo optimization to solve the energy optimization problem corresponding to the maximization of the probability of the graph model created in a Marked Point Process. Besides the color information (which can be modeled by Gaussian mixtures or convolutional neural networks) other properties (such as width, connections, overlapping of vertices, and direction of branches) can be coded by different energy terms corresponding to probability. Our new approach has the advantage that it does not require significant training and can result in a high-level graph representation. We present our initial results in this article thus the recognition of overlapping branches and occlusion by other trees is not presented in this paper.

At present, request/reply data transmission mode is often adopted between industrial application and data acquisition equipment. But they are highly dependent on each other, which reduces the timeliness of data transmission and fails to meet the workshop data flexible demands of industrial applications. In this paper, a workshop data transmission mode based on publish/subscribe communication mode is designed. The message proxy server based on the MQTT protocol is designed in detail, and the publish and subscribe process of the client is analyzed. The test shows that with the increase in the number of subscription clients, the delay of sending messages increases linearly without any surge.
