To study such occurrences; we have considered fluid dynamics of ocean coupled with atmospheric motion. In the present study we have considered the eye of the cyclonic system that consist of fluid dynamical source and fluid dynamical sink at a small distance apart, and thus, constitute the fluid dynamical doublet of the object system. Then the fluid dynamical doublet of the object system and its image system has been considered with respect to a firm wall (here the sea shore). The fluid dynamical equation of complex potential with respect to the object system, the image system and the stream velocity have been undertaken. The complex potential of the object doublet, image doublet and the stream velocity have been considered. The velocity vector, consequently the pressure has been retrieve with the help of Bernoulli’s equation of fluid motion. Then the minimum /maximum pressure on the wall that is on the sea shore has been calculated analytically. Thus, it is found that on the basis of some prevailing conditions existing wind and energy the cyclone or hurricane move towards the sea coast or to the right of its motion.

Refinement of the Matching Coefficients of the Mathematical Model of Spacecraft Motion Using the Concept of “Generalized Observability”

The aim of this paper is to improve the scientific and methodological support of identification tasks when specifying the parameters of spacecraft motion. The article examines a systematic approach to ensuring the specification of the ballistic coefficient in the mathematical model of the spacecraft motion. For emergency situations, an approach was used that takes into account the object–system “task–solution tool”, which allows taking into account the errors of all elements of the navigation tool. The introduced structural property “generalized observability” makes it possible to solve the problem of Sb refinement in traditional and non-traditional conditions in the practice of operational navigation and ballistic support of spacecraft flight.

TECHNOLOGICAL APPROACH TO SOLVING THE PROBLEM OF MINIMIZING THE INFLUENCE OF DESTABILIZING FACTORS ON THE WORK OF DISTRIBUTED STRUCTURES OF THE GROUND-ROCKOTECHNICAL COMPLEX IN AN INTEGRAL PROJECT «OBJECT-SYSTEM»

Mobile structures of the ground-based robotic complex (RTC) are investigated as an active component formation of an integrated project “object-system”, which is operated in a destabilizing environment. The relevant problem of minimizing the influence of external destabilizing factors on the operation of mobile spatially-distributed structures of the ground-based RTC is stated in the descriptions of the conceptual apparatus of complex, poorly formalized multicomponent technical systems. Following the logic of this approach, the basic principles of distributed control are determined and their applications are implemented in the mobile structures of the ground-based RTC with elements of subsidiarity. The quintessence of the latter is represented by the technology of multi-antenna MIMO systems, which made it possible to determine the trade-offs of using classical transmission methods and strategies for receiving and processing MIMO signals in the multi-sensory channels of the information-control system (ICS) and radio communication with the data transmission system and commands. Given the complexity of performing the stated tasks, a set of technological functions of reducing the influence of destabilizing factors and their practical variations in the algorithms for obtaining the target result are proposed. A situational model of reducing (minimizing) information losses at the output of the information-control system of the ground-based robotic complex under destabilization has been built. Options have been proposed to achieve the target result: integration of structural and parametric adaptation methods, MIMO technologies, code division multiplexing techniques with CDMA channels, taking into account the heterogeneity factor of information exchange channels and the artificial redundancy of the system itself with respect to the number of external interference sources.

Track 3.d Introduction: How does design express value?

A general view, often presented in a political context, suggests investment in design may create societal benefits, like economic growth, employment, competitiveness, and convenience. Conducted at a general level with aggregate variables, such measurements provide very limited insights and can even be misleading. A different approach takes a particular view of a designed artefact, object, system or service. Addressing the benefactors, users and consumers, we may be able to reach an individual value, which in turn may be aggregated to assess a market, KPI or similar. How does design express value? And how can we measure the value? To design is to create value for somebody. However, the value depends on who judges it and their and their personal values. According to John Heskett; “Design, stripped to its essence, can be defined as the human capacity to shape and make our environment in ways without precedent in nature that serves our needs and gives meaning to our lives”. (Heskett, 2005). This suggests that artefacts, objects, systems and services, which are available to us, may influence and serve us in different ways depending on our position within a particular environment. Any artefact may affect our physical well-being. This reflects preferences and other values may essentially be emotions and feelings.

Modeling Historically mHealth Care Environments

This article describes how mobile health (mHealth) has grown from infancy stage to toddler stage due to advances in the technology. It has the potential for further growth as it is low-cost health care. For its further growth, it is necessary to widen its scope. In this article, a proposal is presented to develop a new and advanced mHealth care system, and its first step that is modelling is reported. In modelling, historically, a model of a temporal object system (TOS) is used. The model empowers users of the proposed mHealth care system to define, retrieve and manipulate all objects historically, in a uniform fashion, and also to keep historically the changes that occur to the objects. Later, these historically stored objects can be consulted during making essential and crucial decisions about the patients (objects) and other objects of the system, and it can save both lives and money. Also, the stored objects can be used in the future planning and research.

Local System of Positioning Using a Wifi Network

The WiFi technology is widespread. To launch the WiFi network is very simply, thus, they meet so often. Knowledge of the location of the antennas Wi-fi is very important for internal localization (position fix of an object). System of positioning of Wi-fi (WPS) or WiPS/WFPS are used where GPS and GLONASS are unavailable because of different reasons including multipath and signal blocking indoors. Such systems include as well internal systems of positioning. Use of Wi-fi not for creation of a network, and (for example, positioning of devices on the WiFi network) is urgent for other purposes because there is a rapid growth at the beginning of the 21st century of wireless access points in urban areas. This article discusses practical application of a method of localization with use of WiFi of access points which is based on measurement of intensity of the received signal (indication of the received signal or RSSI). Here the device which executes the measurements necessary for system operation is described. Some formulas for computation of layout of the device are given. Results of system operation are considered with different layouts of access points in the given space and different environments.
