Board of Editors

Applications for membership in J.UCS editorial board are generally accepted on a basis of referral only.

External Reviewers

J.UCS would like to thank external reviewers for their support and help with the evaluation of submissions to our journal.

Impact Factor

The 2014 impact factor of the journal is 0.466, the 5-year impact factor is 0.566.

Articles published in J.UCS are indexed and reviewed among others in:

    DBLP Computer Science Bibliography Server
    Web of Science (Thomson Reuters)
    MathSciNet and Mathematical Reviews
    Microsoft Academic Search 


Publishing papers in J.UCS has a number of advantages compared to publications in traditional media:

    The duration of the evaluation process depends entirely on the quality of the submission. From past experience, excellent and innovative papers written in flawless English in an area that is mainstream can pass the evaluation process in less than 4 months. However, if the reviewers demand a revision and hence the authors have to send an improved version followed by a second round of reviews, the evaluation time may be easily twice as much.

    The number of pages as well as the number of papers published in each issue can be varied considerably and according to the need of the authors and the topics of the issues.

    Locating a J.UCS article is easy: all papers can be searched by titles, authors and keywords or accessed directly by the table of contents, by their categorization according to the ACM Computer Clasiffication System and by DOI (digital object identifier).

    J.UCS does not charge any submission or publication fees. The decisive criterion for a possible publication is the scientific quality of the submitted article.

Details concerning submission can be obtained at the URL, refereeing procedure and editorial policy can be found at Articles can be submitted through the web submission form at

There are four categories of papers in J.UCS:

(a) Research contributions: This is the rule, and the majority of papers will be in this area.
Papers of this category will be accepted only if they contain innovative results. The length of the paper must also be taken into account. A short paper is acceptable with fewer innovative results than a longer paper. Research contributions should not be combined with more "survey type" material than is necessary for the paper. Note that research contribution can be reports of projects, if the project has resulted in sufficiently many clearly stated innovations or new results.

(b) Notes: Short research contributions with usually a single but interesting new idea, result or innovation.

(c) Surveys: Usually longer papers, do usually not contain any or much original research but are judged on whether they are well written and give an unbiased and complete survey of the topic at issue.

(d) Papers on J.UCS: These are papers that explain improvements or changes in J.UCS. In this case they may or may not contain novel material. They should be judged on whether they are well-written and understandable and whether the innovative features and changes in J.UCS -something one can usually try out and test- are indeed of interest to at least some parts of the J.UCS community.

Plagiarism check
Authors of submitted papers give an explicit permission to plagiarism check of their submitted (and accepted) articles.

Printed publications

A number of special issues as well as the printed archive editions of volumes 3 to 17 are also avaible in print and can be ordered directly from our office. To do so, fill in a print-out of the order form and send it to Christian Gütl at Prices are inclusive of packing and postage. Delivery time is about 2 weeks, depending on the country of destination. You will received an invoice upon delivery.

Special Issues
J.UCS has published a number of special issues from all areas of computer science.

Guest editors interested in the publication of special issues are kindly requested to consult the guidelines for the publication of special issues at and send the proposal for the special issue to Christian Gütl ( or Dana Kaiser (

If you are interested in contributing to a special issue, please have a look at 'Special Issues in Preparation' where you can find a list of scheduled special issues with the names of the guest editors.


All papers published in J.UCS can be annotated - this feature makes it possible to attach comments, criticisms, cross references, links etc. to the papers. We invite all readers to indeed make use of this possibility! To annotate just click the 'Write a comment' button on the abstract page of a paper. You can now enter your comments. To read a comment, just click on the 'Read comments' button. Each time a comment has been added to a paper, the corresponding author receives an automatic notification and can thus respond to the comment, if desired.

Please notice that the annontations can be posted by all readers, hence J.UCS disclaims responsibility for the contents of the annotations.

Special Issues
Special Issue on Advances in Security and Privacy of Multimodal Interfaces
Submission Date: 2017-10-15

With the rapid development and increasing complexity of multimodal interfaces using multiple modalities of communication in human-computer systems such as speech, tactile, gestures, gaze, head and body movements, facial expressions, gait, electroencephalogram (EEG) and electromyogram (EMG) signals, the user requirements for trust, security, and privacy are becoming more and more demanding. Multimodal interfaces developed for man-machine interactions bring together different computing paradigms such as Physiological Computing, Affective Computing, and Sentimental Computing. Security and privacy are important parts of these systems, and pose open and challenging problems. As the measures employed by the traditional security technologies may not be applicable in every case, we need to build improved multimodal interfaces for various applications in Ambient Assisted Living (AAL), Enhanced Living Environments (ELE), Assistive Technologies, Smart Houses, Internet of Things (IoT) and similar environments that will allow users to enjoy more multimodality of interactions while preserving trust, security, and privacy without losing performance, usability, and affordability of man-machine interactions at the same time. The main objective of this special issue is to collect contributions by leading-edge researchers from academia and industry, and show the latest research results in the rapidly developed field of security and privacy in multimodal interfaces, therefore providing a valuable information venue to researchers as well as practitioners. Manuscripts regarding novel algorithms, architectures, implementations, and experiences are welcome.

Special Issue on Quality & Reliability Engineering: Trends and Future Directions
Submission Date: 2017-10-30

Look at virtually any industry - automotive, avionics, oil, telecommunications, banking, semiconductors, pharmaceuticals - all these are highly dependent on computing for their basic functioning. Science and Technology demand high-performance hardware and high-quality software for making improvements and breakthroughs. Like machinery replaced craftsmanship in the industrial revolution, computers and intelligent parts are quickly pushing their mechanical counterparts out of the market. Contemporary examples of highly complex hardware/ software systems can be found in projects undertaken by Defense, Telecommunications and a variety of other industries. The demand for complex hardware/software systems has increased more rapidly than the ability to design, implement, test and maintain them. When the requirements for and dependencies on computers increase, the possibility of crises from computer failures also increases. Needless to say, the reliability of computer systems has become a major concern for our society. Recent literature is replete with horror stories of projects gone awry, generally as a result of problems traced to software. It makes us wonder whether software is reliable at all, whether we should use software in safetycritical embedded applications. With processors and software permeating safety critical embedded world, the reliability of software is simply a matter of life and death. Are we embedding potential disasters while we embed software into systems?
