The moods and categories of consumers of fashion industry goods analysis in the context of global processes are the main purposes of this study. Methodology. An analytical method was used to study consumer trends in the fashion industry. The main categories of consumers of the fashion industry are determined by the method of synthesis. It is recommended to integrate the obtained categories by the induction method into the marketing activity of the fashion brands. Results. The most important moods of world consumers in the conditions of global world processes were investigated in the work. Four main sentiments have been identifi ed: fear, just resilience, a desynchronized society, and radical optimism. In order to establish the main ways of behavior of players in the market of the fashion industry, the categories of consumers of industrial goods were identifie d: stabilizers, settlers, new optimists. The key areas of new methods of interaction of fashion brands with consumers are the following: - ease of decision-making (sales in stores with a limited range will grow);- quiet trade (rejection of daily uncertainties);- unifi ed commerce (creates uninterrupted interaction with customers on all channels);- referral to archives (resale industry shows signs of acceleration);- hyperlocalized social commerce (possibility of earning a commission for all participants of the offline / online retail chain);- attracting attention to the cities of the second level (shifting attention from oversaturated cities of the 1st level to remote cities of the 2nd level, providing high-speed logistics);- AR / VR purchases (use of virtual reality);- evolution on demand (simplifi cation of US-design (user experience) in the online space                                                                                  - capacity (and savings) of packaging (group purchases at reduced prices, minimization of packaging).The obtained data are recommended for implementation in marketing and management activities of Ukrainian fashion brands.

An escape response is a rapid manoeuvre used by prey to evade predators. Performing this manoeuvre at greater speed, in a favourable direction, or from a longer distance have been hypothesized to enhance the survival of prey, but these ideas are difficult to test experimentally. We examined how prey survival depends on escape kinematics through a novel combination of experimentation and mathematical modelling. This approach focused on zebrafish ( Danio rerio ) larvae under predation by adults and juveniles of the same species. High-speed three-dimensional kinematics were used to track the body position of prey and predator and to determine the probability of behavioural actions by both fish. These measurements provided the basis for an agent-based probabilistic model that simulated the trajectories of the animals. Predictions of survivorship by this model were found by Monte Carlo simulations to agree with our observations and we examined how these predictions varied by changing individual model parameters. Contrary to expectation, we found that survival may not be improved by increasing the speed or altering the direction of the escape. Rather, zebrafish larvae operate with sufficiently high locomotor performance due to the relatively slow approach and limited range of suction feeding by fish predators. We did find that survival was enhanced when prey responded from a greater distance. This is an ability that depends on the capacity of the visual and lateral line systems to detect a looming threat. Therefore, performance in sensing, and not locomotion, is decisive for improving the survival of larval fish prey. These results offer a framework for understanding the evolution of predator–prey strategy that may inform prey survival in a broad diversity of animals.

AbstractOptical measurement systems are an important part of the portfolio of 3D topography sensors. By precise, contactless and rapid measurements these sensors constitute an alternative to tactile instruments. In this contribution the principle of a laser interferometric distance sensor is presented, which in combination with lateral scan axes acts as a topography sensor and also as distance sensor for the compensation of vibrations in a coherence scanning Linnik interferometer. An advantage of this distance sensor is its high acquisition rate of height values, which in case of working as a topography sensor enables high scan velocities as it is demonstrated at a chirp standard measured with a scan velocity of 80 mm/s. This is much higher than the scan velocity of tactile instruments, which are typically limited up to 1 mm/s. In addition, the compensation of vibration disturbances demonstrates the capability of the fast distance measurement.In contrast to other existing high-speed point sensors the relevant components are mass products. This keeps the costs of the sensor setup in a limited range. Furthermore, the sensor shows potential of much higher measurement rates than 116 kHz provided by the sensor used here.

Low noise with wood milling"airface" constructions. The noise surrounds us everywhere, constituting a disruptive component of our lives. In the wood industry it is more than in other industries due to the specificity of wood processing carried out by high-speed tools. GUS data say that in 2012 as many as 53% of employees worked in noise. Hence the necessity of constant search for new methods of noise reduction. One of them is the use of a grooved surface patterned on the plumage of owls in the construction of milling heads. Their characteristic construction makes the flight of owls almost silent. this is possible due to the special construction of ailerons, which form the bearing surface of the wing. The "owl's wing" smoothes the air flow with a serrated edge and scatters the noise. This allows for almost silent flight characteristics without adversely affecting aerodynamics. Leuco has used this concept of learning from nature to make the milling tools even more aerodynamic, and to get further noise reduction effects! Leuco has submitted a patent for this aerodynamic head design called "airface".

AbstractInterference heating effects generated by a blunt fin-type protuberance on a flat plate exposed to a hypersonic flow have been investigated experimentally and numerically. Experiments and simulations were carried out at a free-stream Mach number of 6.7 under laminar flow conditions. The surface heating on the plate was measured experimentally using liquid-crystal thermography, which provided quantitative data with high spatial resolution. Complementary surface oil flow and schlieren experiments were also carried out to gain a better understanding of the interference flow field. The effects of fin leading-edge diameter on the heating distribution on the flat plate surface were explored. The results of the experiments and simulations agree well and reveal a highly complex interaction region which extends over seven diameters upstream of the fin. Within the interaction region surrounding the fin, heating enhancements up to ten times the undisturbed flat plate value were estimated from the experimental data. However, the liquid crystals have a limited range, and the numerical simulations indicated localized peak heating many times this value both on the plate and the fin itself.

The main theoretical and numerical aspects of a design method for optimum contrar-rotating (CR) propellers for fast marine crafts are presented. We propose a reformulated version of a well-known design theory for contra-rotating propellers, by taking advantage of a new fully numerical algorithm for the calculation of the mutually induced velocities and introducing new features such as numerical lifting surface corrections, use of an integrated modern cavitation/strength criteria, a modified method to consider different numbers of blades among the two propellers, and to allow for an unloading function in the search for the optimal circulation distribution. The paper first introduces the main theoretical principles of the new methods and then discusses the influence of the main design parameters on an emblematic example of application in the case of counter rotating propellers for a pod propulsor designed for fast planing crafts (35 knots and above).

The article deals with the proposed 5-axis strategies of high-speed milling of thin-walled parts. I proposed three ways of material take-in. It is an advantage that by this milling the shaft of the tool is not in contact with the machined surface. Each tool contact with the machined surface leaves an unwanted track on the parts surface. Article present new methods for five axes high speed milling flexible parts. Experimental part was five axis high speed milling and measuring quality of surface. Results were evaluated by statistic methods by software Minitab.

We describe new methods for the construction of spiral toolpaths for high-speed machining. In the simplest case, our method takes a polygon as input and a number δ > 0 and returns a spiral starting at a central point in the polygon, going around towards the boundary while morphing to the shape of the polygon. The spiral consists of linear segments and circular arcs, it is G1 continuous, it has no self-intersections, and the distance from each point on the spiral to each of the neighboring revolutions is at most δ. Our method has the advantage over previously described methods that it is easily adjustable to the case where there is an island in the polygon to be avoided by the spiral. In that case, the spiral starts at the island and morphs the island to the outer boundary of the polygon. It is shown how to apply that method to make significantly shorter spirals in polygons with no islands than what is obtained by conventional spiral toolpaths. Finally, we show how to make a spiral in a polygon with multiple islands by connecting the islands into one island.

Purpose – Fashion and textile industry has confronted to participate with the sustainable industry and society proactively not by the government regulations, but by the shareholders or consumers driven with corporate social responsibility. The purpose of this paper is to consider methods applied for the sustainability of products according to Korean domestic fashion and textile companies and clothing types and to investigate the limitation of current sustainability methods of companies. Design/methodology/approach – The study used document analysis and case studies of 396 companies. The study looked into newspapers, monthly magazines, and publications of fashion companies and internet web sites of almost every possible type that have been issued to date and analyzed the previous studies as well. Findings – The companies’ strategies are of three groups, the uses of environmental friendly materials: 36.9 percent (natural fibers, recycled fibers and biodegradable fibers), apparel reuse: 4.5 percent (remodeling/alteration and transform/combination with more materials), and eco-marketing promotions: 58.6 percent. For women’s and casual wear section, the methods used with organic materials and the green-campaign messages appeared frequently, while in the men’s wear section, coolMapsi, 0or warm OnMapsi for business wear did a lot for the low indoor energy consumption, such as no neck-tie in the hot season or wearing underwear in the cold season. Originality/value – Fashion and textile products have provided the key solutions for the generation’s happiness, identity, value, self-realization, health and role. There have been the low quality and similarity of fashion products from mass production and high speed and we should consider sustainability for the next generation and society. But the current problem in the industry is that most of eco-product developments are only short term. Also, from the high cost of eco materials and processes, there is a limited portion of sustainability section among total products and low design quality of fashion or the low profit outcomes.
