The article proposes the implementation of a specific information system for ensuring the in-formation security of the enterprise. The peculiarities of the international standard ISO/IEC-15408, which is a methodology of tasks, assessments and a catalog of IT security requirements have been studied and analyzed. The specifics of the application of general security criteria have been defined and the use of Active Directory services has been proposed as an example of the implementation of General Criteria at the enterprise.

Abstract:

Enterprise Information Technology Systems are major corporate assets upon which corporate management and operations are heavily dependent. Current accounting standards for the treatment of these assets have not kept pace with advances in technology, such as models for creating and evolving IT. Capitalizable costs according to the standards are principally primary development costs and exclude system evolution. This weakness of the standards creates a disproportionate downward bias in the book value of software and in current earnings, as costs incurred for on-going systems evolution is five to

Abstract Most engineering software tools use typical menu-based user interfaces, and they may not be suitable for learning tools because the solution processes are hidden and students can only see the results.

The geometry of beam sections is sketched, and a shape matching technique is used to recognize the sketch. Various beam loads are added by sketching gestures or writing singularity functions.

This paper presents a multi-modal human emotion recognition web application by considering of three traits includes speech, text, facial expressions, to extract and analyze emotions of people who are giving interviews. Now a days there is a rapid development of Machine Learning, Artificial Intelligence and deep learning, this emotion recognition is getting more attention from researchers. These machines are said to be intelligent only if they are able to do human recognition or sentiment analysis. Emotion recognition helps

Abstract:

The mechanism on how lightning detection system (LDS) operated never been exposed by manufacturer since it was confidential. This scenario motivated the authors to explore the issue above by using MATLAB to develop autoanalysis software based on the feature extraction. This extraction is intended for recognizing the parameters in the first return stroke, and compare the measurement between the autoanalysis software and the manual analysis. This paper is a modification based on a previous work regarding autoanalysis of zero-crossing time and initial peak of return stroke using features extracti

There are two important territories in Slovakia with functioning gas well operations: the Eastern Slovak Lowland and the Vienna Basin. This article focuses on the creation of electronic monitoring and graphical mapping of the current technical conditions of gas wells in the Eastern Slovak Lowland. An analysis of the gas wells’ current state in the terrain is available. The aim of the article is to draw attention to the current state of gas wells, such as the insufficient processing of gas wells, the lack of summary and uniform records concerning them, and the lack of an electronic system for m

The past three decades have seen phenomenal growth in investments in the area of product lifecycle management (PLM) as companies exploit opportunities in streamlining product lifecycle processes, and fully harnessing their data assets. These processes span all product lifecycle phases from requirements definition, systems design/ analysis, and simulation, detailed design, manufacturing planning, production planning, quality management, customer support, in-service management, and end-of-life recycling. Initiatives ranging from process re-engineering, enterprise-level change management, standar

Abstract:

The theory and applications of Smart Factories and Industry 4.0 are increasing the entry into the industry. It is common in industry to start converting exclusive parts, of their production, into this new paradigm rather than converting whole production lines all at once. In Europe and Sweden, recent political decisions are taken to reach the target of greenhouse gas emission reduction. One possible solution is to replace concrete in buildings with Cross Laminated Timber. In the last years, equipment and software that have been custom made for a certain task, are now cheaper and can be adapted

Abstract:

Many VR platforms emphasize extensibility to support as wide a range of applications as possible. The current trend is to move this extensibility to lower levels of the system to support extensibility of infrastructure mechanisms such as networking protocols. This kind of extensibility allows the runtime of the virtual environment system to evolve even while the system is running. This paper presents a new virtual environment platform that allows multiple infrastructure mechanisms to be added to and coexist within the running system, with different elements of the virtual world using different

Abstract:

The system of automatic license plate recognition (ALPR) is a combination of software and hardware technologies implementing ALPR algorithms. It seems to be easy to achieve the goal but recognition of license plate requires many difficult solutions to some non-trivial tasks. If the license plate is oriented horizontally, uniformly lighted, has a clean surface, clearly distinguishable characters, then it’ll be not too difficult to recognize such a license plate. However, the reality is much worse. The lighting of each part of the plate isn’t equal; the picture from the camera is noisy. Besides,

SUMMARYIn this paper, the robust, optimal, output control problem is dealt with for a 3-degree-of-freedom laboratory helicopter. The control goal is to achieve the practical tracking of the desired elevation and pitch angles without the angular velocity feedback. A nominal linear time-invariant system is introduced and the real system is considered as the nominal one with uncertainties, including parameter perturbations, nonlinear time-varying uncertainties, and external disturbances. An observer is first used to estimate angular velocity. Then a nominal controller based on the optimal control

This article proposes a method to identify and mitigate unwanted packets and traffic, especially duplicate packets, in cloud computing environments. The method includes creating an Intrusion Search and Detection (IF-AD) system to securely maintain user information and allocate secondary memory. To detect unwanted traffic, this method compares the size of the downloaded file with the original file, identifying any differences

The problem of constructing a control system for underwater vehicles is relevant due to the growing scope of their application, including acting in autonomous modes. Moreover, it is required to have an ability to use these devices both in quasi-stationary and close to pulsed mode. Thus, it is necessary to develop a mathematical model of vehicle’s dynamics for autonomous operations of an unmanned underwater vehicle (UUV), which would describe the dynamics of motion as close as possible to the real one.

Within emerging markets, ensuring the competitiveness of manufacturing companies is crucial to their success. The integration of new business possibilities, such as Product-Service-Systems (PSS) can provide one suitable solution. Especially within the architecture development process, large amounts of interconnected data and data types need to be processed and versioned. This leads to a significant lack of data consistency and continuity along the development process of modular PSS architectures. This lack of consistency and continuity leads to a process being prone to errors, representing a s
