<p>In view of new communication and information technologies that appeared with the emergence of networks and Internet, the computer security became a major challenge, and works in this research axis are increasingly numerous. Various tools and mechanisms are developed in order to guarantee a safety level up to the requirements of modern life. Among them, intrusion detection and prevention systems (IDPS) intended to locate activities or abnormal behaviors suspect to be detrimental to the correct operation of the system. The purpose of this work is the design and the realization of an IDPS inspired from natural immune systems. The study of biological systems to get inspired from them for the resolution of computer science problems is an axis of the artificial intelligence field which gave rise to robust and effective methods by their natural function, the immune systems aroused the interest of researchers in the intrusion detection field, taking into account the similarities of NIS (Natural Immune System) and IDPS objectives. Within the framework of this work, we conceived an IDPS inspired from natural immune system and implemented by using a directed approach. A platform was developed and tests were carried out in order to assess our system performances.</p>

A self-adaptation method for natural-coordinate systems is proposed, in order to automate the selection of natural coordinates for each rigid element of a multibody system. The four-step method includes: First, find out all empty positions, which come from the feature points or vectors of the joints attached to the element, and give equal weight to them; second, delete redundant empty positions and add their weight to the unique one; third, select at most four empty positions which have a maximum total weight and can be occupied by a natural-coordinate system at the same time; fourth, the standard natural-coordinate system on the element can adapt itself to the selected empty positions, leading to an actual natural-coordinate system, which contains twelve rational natural coordinates for the element. The implementation of the method has been achieved on a multibody dynamics and motion analysis platform, InteDyna, with the result that modeling efficiency is enhanced and model quality improved.

The Modulation Transfer Function (MTF) is a wellestablished measure of camera system performance, commonly employed to characterize optical and image capture systems. It is a measure based on Linear System Theory; thus, its use relies on the assumption that the system is linear and stationary. This is not the case with modern-day camera systems that incorporate non-linear image signal processes (ISP) to improve the output image. Nonlinearities result in variations in camera system performance, which are dependent upon the specific input signals. This paper discusses the development of a novel framework, designed to acquire MTFs directly from images of natural complex scenes, thus making the use of traditional test charts with set patterns redundant. The framework is based on extraction, characterization and classification of edges found within images of natural scenes. Scene derived performance measures aim to characterize non-linear image processes incorporated in modern cameras more faithfully. Further, they can produce ‘live’ performance measures, acquired directly from camera feeds.

Technological progress is characterized by continuous expansion of automation of all sectors of human activity, the transition from partial automation to integrated, and then from integrated automation to complete, which provides the highest technical and economic efficiency. The 21st century is called the information age, because the main successes of technological progress are now observed precisely in the introduction of information technology to various means and systems of automation. Automation is not possible without measuring equipment. The development of control and measurement technology for automation systems is largely determined by advances in compatible fields of science and technology - in microelectronics, computing, solid state physics, etc. It is for the developers of automation systems and control of various technological parameters that the most favorable environment of practical activity is now created in the form of a huge nomenclature of miniature and reliable sensors, which are easily combined with secondary equipment and allow to transmit measurement information over long distances in the conditions of intensive industrial interferences. Temperature measurement and control tools have long been at the forefront of automated control of many technical processes, the complication of which leads to the need for a sharp increase in the number of measurement channels to obtain complete and objective information about the temperature modes of the processes. In this regard, a computerized temperature control system for crude natural gas air coolers (APOs) is no different than sophisticated industrial automation systems. Given the fact that gas pipelines are an important part of the industrial complex of Ukraine, the development of a modern computerized temperature control system for air coolers for raw natural gas is, without doubt, an urgent scientific and technical task.

The article discusses the concept of a natural recreational system (NRS) as a set of interconnected areas of inaccessibility, tourists, regulatory authorities and service personnel. For the development of tourism in natural areas, it is necessary to study the connections between these subsystems, which determined the purpose of the study – to structure the NRS, for which it is necessary: to study the subsystem of tourists, engaged in various types of nature-oriented tourism; examine the subsystems of regulatory bodies and service personnel and determine their functions; to analyze the mutual influence of four NRS subsystems. The first subsystem includes areas of inaccessibility, on the territory of which different types of travel are carried out. The second subsystem consists of tourists traveling in areals of inaccessibility, where they are engaged in nature-oriented, active, sports, ecological and extreme tourism, as well as recreation. The third subsystem consists of bodies that control tourist processes in areas of inaccessibility. This includes the Ministry of Emergencies, which regulates the activities of search and rescue services responsible for search and rescue on the territory of Russia. Route qualification commissions are the controlling body of sports tourism. Insurance companies can interact with tourists involved in all types of nature tourism. The fourth subsystem is optional; it consists of service personnel and, in some cases, tourist infrastructure. At the same time, there are direct and feedback links between the subsystem of tourists and the subsystems of regulatory bodies and service personnel. There are only direct links between the tourist subsystem and areals of inaccessibility.

AbstractWe present a new axiomatization of classical mereology in which the three components of the theory—ordering, composition, and decomposition principles—are neatly separated. The equivalence of our axiom system with other, more familiar systems is established by purely deductive methods, along with additional results on the relative strengths of the composition and decomposition axioms of each system.

One of the potential hazards that can cause major problems in coastal areas is erosion. In order to solve this problem, the notion of sustainable coastal development has garnered growing attention around the world. Coastal zone management mechanisms aim to ensure the sustainability of resources and the environment. For example, natural coastal protection using vegetation such as mangrove trees is currently preferred in many places in the world. However, there are challenges in the development of this natural form of coastal protection, e.g. mangrove seedling trees can be damaged by the waves or the current before they grow strong enough, and thus require appropriate protection until at least two years after planting. To solve this problem, a natural coastal protection system that combines a main natural protection and a temporary man-made structure is proposed. After a process of weighing temporary man-made-structure alternatives, the geobag dyke was selected. This study aimed to quantify the effects of various geobag dyke configurations and geobag unit weights on wave height reduction. Laboratory experiments were conducted on a narrow wave flume using a mangrove model as main natural protection and geotextilegeobag models as temporary man-made structures. Various wave conditions were generated during the laboratory tests. This paper focuses on the experimental results of wave transmission through the protection system in order to determine the most effective geobag dyke configuration to reduce the wave height. Based on experimental modelling, the most effective geobag dyke configuration uses relatively heavy geobag units with a moderate dyke slope (1:1.5).

AbstractHistorically, the principal function of vision has been to provide the information needed to support action. Visually mediated actions rely on three systems: the gaze system responsible for locating and fixating task-relevant objects, the motor system of the limbs to carry out the task, and the visual system to supply information to the other two. All three systems are under the control of a fourth system, the schema system, which specifies the current task and plans the overall sequence of actions. These four systems have separate but interconnected cortical representations. The way these systems interact in time and space is discussed here in relation to two studies of the gaze changes and manipulations made during two ordinary food preparation tasks. The main conclusions are that complex action sequences consist of a succession of individual object-related actions, each of which typically involve a turn toward the object (if needed), followed by fixation and finally manipulation monitored by vision. Gaze often moves on to the next object just before manipulation is complete. Task-irrelevant objects are hardly ever fixated, implying that the control of fixation comes principally from top-down instructions from the schema system, not bottom-up salience. Single fixations have identifiable functions (locating, directing, guiding, and checking) related to the action to be taken. Several variants of the basic object-related action scheme are discussed, including single-action events in ball sports involving only one anticipatory gaze shift, continuous production loops in text and music reading, and storage–action alternation in copying tasks such as portrait sketching.

Scripting is a widely-used way to automate the execution of tasks. Despite the popularity of scripting, it remains difficult to use for both beginners and experts: because of the cryptic commands for the first group, and incompatible syntaxes across different systems, for the latter group. The authors introduce Natural Shell, an assistant for enabling end-users to generate commands and scripts for various purposes. Natural Shell automatically synthesizes scripts for different shell systems based on natural language descriptions. By interacting with Natural Shell, new users can learn the basics of scripting languages without the obstacles from the incomprehensible syntaxes. On the other hand, the authors' tool frees more advanced users from manuals when they switch shell systems. The authors have developed a prototype system and demonstrate its effectiveness with a benchmark of 50 examples of popular shell commands collected from online forums. In addition, the authors analyzed the usage of Natural Shell in a lab study that involves 10 participants with different scripting skill levels. Natural Shell effectively assists the users to generate commands in assigned syntaxes and greatly streamlines their learning and using experience.

Natural Language Processing (NLP) systems involve Natural Language Understanding (NLU), Dialogue Management (DM) and Natural Language Generation (NLG). The purpose of this work involves integrating learning with examples and rule-based processing to design an NLP system. The design involves a three-stage processing framework, which combines syntactic generation, semantic extraction and a strong rule-based control. The syntactic generator generates syntax by aligning sentences with Part-of-Speech (POS) tags limited by the number of words in the lexicon. The semantic extractor extracts meaningful keywords from the queries raised. The above two modules are controlled by generalized rules by the rule-based controller module. The system is evaluated under different domains. The results reveal that the accuracy of the system is 92.33% on an average. The design process is simple, and the processing time is 2.12 seconds, which is minimal compared to similar statistical models. The performance of an NLP tool in a certain task can be estimated by the quality of its predictions on the classification of unseen data. The results reveal similar performance with existing systems indicating the possibility of usage for similar tasks. The system supports a vocabulary of about 700 words and can be used as an NLP module in a spoken dialogue system for various domains or task areas.

Abstract To date, social vulnerability research has focused primarily on the individual and household levels, and on social institutions relevant to these two benchmarks. In this paper, a widening of the perspective of social vulnerability to natural hazards is proposed to include socio-structural aspects. For a number of reasons, the sociological system theory, which is inextricably linked with the name of Niklas Luhmann, is an obvious choice for this undertaking. Firstly, Luhmann developed a consistent social theoretical definition of risk, which has significantly influenced risk and hazard research in social science. Furthermore, the system theory provides a theory of society that claims to be able to cover all social levels and to describe all social phenomena. The system theory assumes that in modern society social systems are formed of communications. Therefore, in this paper the view is taken that a system-theoretical inspired concept of social vulnerability must also assess communication. First, this paper describes empirical observations about the vulnerability of social systems. This is achieved on the one hand through a categorisation of four forms of social vulnerability. On the other hand, it is based on examples of vulnerability to flood risks in selected social systems. Finally, consideration is given to a system-theoretical concept of social vulnerability that sees the sensitivity of a social system in each of the respective system structures. Vulnerabilities can only be observed for a particular social system, because the configuration of system structures differs from system to system. These fundamental considerations have to be further explored infuture work on a consistent social theoretical concept of vulnerability.

Natural gas is one of the replacements as a cleaner source with a more suitable calorific value than oil in comparison with other renewable energy sources. Therefore, utilization of natural gas as the main source of replacement strategies in the energy system has accelerated at the national level. However, the natural gas energy system is a complex system including different influencing and influenced variables that affect social and economic factors. This research has developed a system dynamics model to understand the complexity of the natural gas energy systems at the macro-level. The model shows the effective sub-systems of energy system with their related variables. It helps to predict the effective factors of an energy supply system based on statistics approaches. After that, three scenarios are defined based on expert opinions and the behaviors of the sub-systems in each scenario is analyzed. The approach also helps to understand unknown consequences of a decision or scenario in the energy system.

In this paper, we analyze incident response management work using free-formed information that is important for incident response communication. We develop a standard operating procedure for the work and study a support method based on a language processing technology to prevent missing or overlapping necessary tasks and optimize management of progress and integration management of related tasks. A prototype system was developed and evaluated in a workshop held by a local government, or in an exercise. As a result, it is confirmed that the use of language processing technology can make incident response management work efficient.

Many known inhibitors of the bacterial type III secretion system (T3SS), a virulence factor used by pathogenic bacteria to infect host cells, are natural products. These compounds, produced by bacteria, fungi, and plants, may have developed as prophylactic treatments for potential attack by bacterial pathogens or as an attempt by symbiotic organisms to protect their hosts. Regardless, better understanding of the structures and mechanisms of action of these compounds may open opportunities for drug development against diseases caused by pathogens utilizing the T3SS. This review will cover selected known natural products of the T3SS and detail what is known of their origin and mechanism of action. These inhibitors highlight nature’s ability to modulate interactions between organisms at a cellular level.
