Abstract

Abstract Nowadays, the growth and complexity of functionalities of current information systems, especially dynamic, distributed and heterogeneous information systems, makes the design and creation of such systems a difficult task and at the same time, strategic for businesses. A very important stage of data protection in an information system is the creation of a high level model, independent of the software, satisfying the needs of system protection and security. The process of role engineering, i.e. the identification of roles and setting up in an organization is a complex task. The paper presents the modeling and design stages in the process of role engineering in the aspect of security schema development for information systems, in particular for dynamic, distributed information systems, based on the role concept and the usage concept. Such a schema is created first of all during the design phase of a system. Two actors should cooperate with each other in this creation process, the application developer and the security administrator, to determine the minimal set of user’s roles in agreement with the security constraints that guarantee the global security coherence of the system.

Abstract

Abstract The purpose of this paper is to present a multichannel ultrasonic range finder which was designed for the navigation system for blind people. A substantial number of consultations with blind people in the Blind People Centre in Krakow have shown that the navigation and obstacle detection with a help of a white stick only, is not sufficient enough to assure a high safety level. Electronic aids which are being designed for blind people should be mobile, comfortable and low-powered. That is why the MOBIAN© (a mobile safety system for the blind) project is being carried out by the authors to create a highly reliable safety navigation system for blind people. It could not only improve blind people quality of life but also their safety, especially when they are walking in unknown areas. As a part of this project, the multichannel ultrasonic range finder was designed, produced and tested. The tests have proven the device is capable of detecting objects from different directions in a range over 4 m. The device interface is easy to manage and can be controlled by almost any microcontroller or FPGA chip. The designed range finder is to be implemented in the electronic assistant project for blind people. Other systems, including the industrial ones, for instance, mobile robots or gates that count people entries, could benefit from this multichannel range finder. Usually, some low-cost ultrasonic range finders use two transducers for each channel (a transmitter and a receiver). The designed device employs only one transducer per channel which minimizes the end-device size and cost and at the same time provides with the main functionality. Novelty of this device is its multichannel design and the emplacement of the ultrasonic transducers, which can be used due to the application of the multichannel analog multiplexer. Thus, it is possible to detect obstacles, even the inclined ones, with higher reliability and increase the safety of blind people while walking. Also, this design and the transducers’ placement allow to detect obstacles much quicker, when the blind user suddenly turns.

 Manuscript submission for review


The Bull. Pol. Ac.: Tech is now employing a Web-based manuscript submission and peer-review tracking system called Editorial System. Authors must submit their manuscript electronically on the web http://www.editorialsystem.com/bpasts/. From this entry page, access can be obtained to all information required for the submission of a manuscript. First‐time users must create an Author’s account to obtain a user ID and password required to enter the system. All manuscripts receive individual identification codes that should be used in any correspondence with regard to the publication process. For the authors already registered in the Editorial System it is enough to enter their username and password to login as an author (Sign in). Author(s) will be notified about registration and manuscript review process by e-mail.
The manuscripts must be uploaded as a single PDF file.
If you experience difficulties with the manuscript submission website, please contact the Editorial Office of the Bull. Pol. Ac.: Tech (Mrs Ewa Trojanowska: bulletinpas.et@gmail.com or Mrs Anna Jurkiewicz bulletinPAS@gmail.com).Names of authors and their affiliation should be removed from the manuscripts for the review process in order to have a fair evaluation of their manuscript. All authors of the manuscript are responsible for its content; they must have agreed to its publication and have given the corresponding author the authority to act on their behalf in all matters pertaining to publication. The Corresponding Author is responsible for informing the coauthors of the manuscript status throughout the submission, review, and production process.


 Manuscript preparation


1. The manuscript should be written in clear and concise English (UK version).

2. For manuscript preparation please use the Word or LaTeX template available in the Information for Authors on http://www.editorialsystem.com/bpasts/

3. Please remember, that in the .pdf version of the manuscript uploaded in the Editorial System for evaluation process, author(s) name(s) and affiliation should be removed.

4. Authors should consult a recent issue of the journal for style if possible.
 

Manuscript decision and Proofs:

Manuscript evaluations are assigned one of four outcomes: Accept, Minor Revisions, Major Revisions, and Reject. Manuscripts requiring "Minor Revision" not require a second review. All manuscripts receiving a "Major Revision" evaluation must be subjected to a second review. Rejected manuscripts are given no further consideration. Normally, manuscripts that receive a "Major Revision" decision have only one additional chance for revision and the revised version should be uploaded to the Editorial System within six weeks. If the author(s) failed to make satisfactory changes, the manuscript is rejected. On acceptance, manuscripts are subject to editorial amendment to suit house style.

Transfer of Copyright Agreement

Once the paper is initially accepted, the authors are assumed to have transferred the copyright of the paper to the publisher. Please fill the Form, available on the webpage http://www.degruyter.com/view/supplement/s23001917_Open_Access_License.pdf

Sign it, and add to the final version of the manuscript as separate .pdf file.


Proofs will be sent to the author (first named author if no corresponding author is identified of multi-authored papers) and should be returned within48 hours of receipt.
