Opis:
This paper proposes a model to allocate photovoltaic unit (PVU) and distribution static compensator (DSTATCOM) that incorporate the operation effect of PVU in sizing and sitting problem. The model is based on the dynamic assessment of PVU production and the effect of it on placement of PVU and DSTATCOM. Geographical conditions are interfered in placement problem of PVU and DSTATCOM simultaneously. The model is verified in a multi-objective form. The multi-objective problem is formulated based on voltage stability, liability, power loss and total cost of PVU and DSTATCOM. This problem is solved by employing optimization techniques and the results of optimization processes are tested in different scenarios. Uncertainty in network loads is an inevitable task that should be considered in network planning. Uncertainty in the presented model has been defined as a set of divided parts in the presented model. The proposed model has been evaluated on two test systems, 30 bus and 69 bus. The obtained results indicate that the presented model can be employed to study the intermittent behavior of PVU in placement problem.

Opis:
Procesy globalne, obejmujące wszystkie dziedziny życia nie pozostawiają na uboczu również architekturę. W interesach naukowej wspólnoty jest wyprzedzenie i prognozowanie procesów społecznych. Podczas analizy problemów i tendencji teraźniejszości powstaje nie tylko problem naukowej obserwacji, ale i potrzeba uporządkowywania i skierowywania obiektywnych procesów do potrzebnego i pożytecznego społeczeństwu łożyska. Jednym z takich globalnych zjawisk jest fala międzynarodowej nieuregulowanej migracji, architektoniczny aspekt danego zjawiska zasługuje na oddzielne badanie i wyodrębnienie.
Global processes that cover all areas of life do not leave aside architecture as well. Interests of the scientific community have the forecast and prediction of social processes. Analyzing the present problems and trends appears not only the problem of scientific observation, but also the need for ordering and directing objective processes in the necessary channel useful for society. One of such global phenomena is a wave of unregulated international migration, the architectural aspect of this phenomenon deserves a separate study and separation.

Opis:
Utilization of drones is going to become predominated in cellular networks as aerial base stations in order to temporary cover areas where stationary base stations cannot serve the users. Detecting optimal location and efficient number of drone-Base Stations (DBSs) are the targets we tackle in this paper. Toward this goal, we first model the problem using mixed integer non-linear programming. The output of the proposed method is the number and the optimal location of DBSs in a two-dimension area, and the object is to maximize the number of covered users. In the second step, since the proposed method is not solvable using conventional methods, we use a proposed method to solve the optimization problem. Simulation results illustrate that the proposed method has achieved its goals.

Opis:
An article herein presents an optimization model, designated for computational core of decision-taking support system (DTSS). DTSS is necessary for system analysis and search of optimal versions for cyber security facilities placement and information protection of an enterprise or organization distributed computational network (DCN). DTSS and a model allow automize the analysis of information protection and cyber security systems in different versions. It is possible to consider, how separate elements, influence at DCN protection factors and their combinations. Offered model, in distinction from existing, has allowed implementing both the principles of information protection equivalency to a concrete threat and a system complex approach to forming a highly effective protection system for DCN. Hereby we have presented the outcomes of computational experiments on selecting the rational program algorithm of implementing the developed optimization model. It has been offered to use genetic algorithm modification (GAM). Based on the offered model, there has been implemented the module for adaptive DTSS. DTSS module might be applied upon designing protected DCN, based on preset architecture and available sets of information protection and cyber security systems in the network.

Opis:
In this paper the statement of the problem is formulated and the mathematical model of optimization the placement of the undirected planar geometrical objects with piecewise non-linear boundaries in the multiply area is developed. It is shown the geometrical interpretation and derived the estimate of the number of restrictions in the model. On the basis of a mathematical model for finding the global extremum of the objective function was proposed modified method of branches and boundaries. It is also shown the solutions tree that takes into account the problems of optimal placement of undirected planar geometrical object with piecewise nonlinear boundaries in the multiply area, and received the complexity of this method. For locally optimal solutions of the problem modified simulated annealing method has been developed. Thus the analytical expressions for the function of energy system were received, the function, that describes the decrease of temperature over time, function that forms a new state of system. The method of formation the new state of the system was investigated in more detail, which is based on a random permutation of numbers the pair of the objects, it is also based on a consistent placement of objects according to reshuffle their numbers and determining the probability of transition to a new state. It is shown the example of determining permissible points of placement the local coordinate system of the specific geometrical object. The conclusion is that to solve practical optimization problems of placement of the undirected planar geometrical objects with piecewise non-linear boundaries in the multiply area should be used the modified simulated annealing method.

Opis:
Owing to expensive cost and restricted structure, limited sensors are allowed to install in modern systems to monitor the working state, which can improve their availability. Therefore, an effective sensor placement method is presented based on a VIKOR algorithm considering common cause failure (CCF) under epistemic uncertainty in this paper. Specifically, a dynamic fault tree (DFT) is developed to build a fault model to simulate dynamic fault behaviors and some reliability indices are calculated using a dynamic evidence network (DEN). Furthermore, a VIKOR method is proposed to choose the possible sensor locations based on these indices. Besides, a sensor model is introduced by using a priority AND gate (PAND) to describe the failure sequence between a sensor and a component. All placement schemes can be enumerated when the number of sensors is given, and the largest system reliability is the best alternative among the placement schemes. Finally, a case study shows that CCF has some influence on sensor placement and cannot be neglected in the reliabilitybased sensor placement.

Opis:
The phenomenon of internet infl uencers is among the most discussed issues in marketing to children. The amount of time children spend on the internet increases every year, which increases the risk of becoming the target of infl uencer marketing. Studying the impact of infl uencers on children is of great importance not only for marketers, but also for parents responsible for upbringing their off spring. This article presents the results of a qualitative study aimed at describing three components of the attitude (cognitive, emotional and behavioural) of children and parents towards children infl uencers. The methods employed in this study are focus group interviews and individual in-depth interviews with 18 participants: children aged 8–11 and their parents. During the interviews, one sample YouTube video and two TikTok children influencer videos were presented. The analysis of cognitive aspects of attitude showed that children have a higher level of awareness of product placement in influencer video than their parents suspect. Many parents declare that they are against such content on social media, while children see nothing wrong with promotional content and believe that it is natural. As far as the emotional aspect of attitude is concerned, parents present a wider range of emotions than children, possibly because they are less familiar with such content. Being exposed to product placement in influencer videos also impacts the behavioural aspect of attitude. Children are eager to have the promoted products, but parents are sceptical about such products and declare that they buy them only for special occasions.

Opis:
Stenting is one of the most important methods to treat atherosclerosis. Due to its simplicity and efficiency, the use of coronary stents in interventional procedures has rapidly increased, and different stent designs have been introduced in the market. In order to select the most appropriate stent design, it is necessary to analyze and compare the mechanical behavior of different types of stents. In this paper, the finite element method is used for analyzing the behavior of stents. The aim of this work is to investigate the expansion characteristics of a stent as it is deployed and implanted in an artery containing a plaque and propose a model as close to real conditions of stent implantation as possible. Furthermore, two commercially available stents (the Palmaz-Schatz and Multi-Link stents) are modeled and their behavior during the deployment is compared in terms of stress distribution, radial gain, outer diameter changes and dogboning. Moreover, the effect of stent design on the restenosis rate is investigated by comparing the stress distribution in the arteries. The results show the importance of considering the plaque in finite element simulation of mechanical behavior of the coronary stent. According to the findings, the possibility of restenosis is nonsignificantly lower for the Multi-Link stent in comparison with the Palmaz-Schatz stent, which is in good agreement with clinical results.
