Submission of Manuscript
Manuscripts submitted to Computer Technology and Application are considered on the understanding that they have not been published, and are not under consideration for publication, elsewhere; and that all persons entitled to authorship have been named and have approved the final version of the submitted manuscript. Submitting authors should declare this information in the covering letter.
All manuscripts submitted will be considered for publication. Manuscripts should be sent online or as an email attachment to: firstname.lastname@example.org; email@example.com; firstname.lastname@example.org; email@example.com.
Review procedure and editorial policy
Is my paper suitable for Computer Technology and Application?
Computer Technology and Application is asked to consider an increasingly large number of papers. To maximise the number published we are expanding the journal in size. It is, however, not possible to keep pace with the number of submissions and consequently competition for space is high with a current acceptance rate lower than 50%. All the Computer Technology and Application submissions should focus on timely research that provides new insights into the broad principles of computer science. The original research should address clear hypotheses or questions and offer new insights on topics of interest to a broad cross-section of our readers. Studies that report incremental advances or are narrow in scope are not appropriate.
If you are unsure whether your paper falls within the scope of Computer Technology and Application you may submit a pre-submission inquiries; send the abstract of your paper together with a letter explaining the importance of your findings to the Managing Editor (firstname.lastname@example.org; email@example.com).
Authors should include answers to the following questions (max. 50 words per question) in a covering letter, to help the Editors decide whether to send the manuscript for peer review:
(1) What hypotheses or questions does this work address?
(2) How does this work advance our current understanding of computer science?
(3) Why is this work important and timely?
What happens during review?
All manuscripts are allocated to a relevant member of the Editorial board, who decides whether the paper should go forward to peer review. Those that do not will be returned at this stage; we make every effort to do this as quickly as possible (usually within seven days) so that the authors can take their work forward without delay. Papers sent out for review will, typically, be assessed by two or three independent referees. Authors may nominate potential referees. These should not have been co-authors or collaborators within the past 2 years, nor should they have any other conflict of interest. If authors wish to request the exclusion of certain reviewers specific justification must be provided in the covering letter for the Editor’s consideration.
Editors make a final decision based on the referees’ advice balanced with the editorial policy of the journal to either accept subject to revision, reject with resubmission encouraged (where it is likely that further work or major revisions will bring the paper to Journal standards) or reject (where the work typically has technical problems and/or fails to meet our standards regarding novelty, insight and significance). Revised manuscripts must be received by the date stated by the Editor in the decision letter; if received after this date, the manuscript will be treated as a new submission. Revised manuscripts may be sent for further review, at the Editors’ discretion. All resubmitted manuscripts will be treated as new submissions and undergo the full review system. The Computer Technology and Application is committed to rapid publishing. To this end, we strive to return the Editor’s decision and reviewer comments within 30 days of submission and to publish papers within three months of the acceptance date.
Original research articles comprise the largest section of the journal and include Full papers, Rapid reports and Methods. Full papers report complete studies that provide new and valuable insights in to computer science. Rapid reports differ in that the nature of the findings makes priority publication of particular scientific importance, and your covering letter must state clearly why this is considered to be the case. Methods papers should still typically focus, as with any other submission, on timely research that addresses fundamental questions in computer science. However, the novel or improved methodology/analytical approach will form an important component, and description and proper evaluation will be a significant proportion of the paper. Papers which only evaluate a new method/analytical approach or critically examine existing practice, will also be considered, where the conclusion is of wide interest to computer scientists.
Computer Technology and Application also accepts articles that contain comment and review. Do refer to recent issues of the journal for guidance on the types of format that are acceptable. Up to 1500 words is usual, with 1-2 figures as appropriate, but there are no specific restrictions. Short Research reviews will be in the range 3500-4000 words, with up to 40 references and four figures. Following a short introduction putting the area into context, and providing a “way in” for the non-specialist, these will concentrate on the most recent developments in the field. Enquiries or suggestions about these or other types of article are always welcome.
Style notes for all submissions
Use Times New Roman font, pt-size 10.5. Lines and pages should be numbered (to aid review use continuous numbering for lines). Both American and British English are acceptable.
Where authors have different addresses, use numbered superscripts to refer to each address provided. The format of authors’ affiliations should be: 1. Department of ***, University of ***, City name, State name, Postal code, Country name. State the author for correspondence and include their research fields and email details.
A Total word count for the main body of the text (Introduction, Materials and Methods, Results and Discussion, Conclusion and Acknowledgements), word counts for each section plus the number of figures and tables must be stated on the front page.
Arrange research papers under the headings Abstract, Keywords, Introduction, Materials and Methods, Results and Discussion, Conclusion, Acknowledgements and References. In the case of Modelling or Theory papers, include a heading of Description in place of Materials and Methods, to include description of the model or theoretical framework.
The Abstract for research papers, which must be usable as a stand-alone document, must not exceed 250 words and only one paragraph can it be contained, which should include the research conducted, including the rationale, methods, key results and the main conclusion, including key points of discussion. It should not contain citations of other papers. For reviews, keep to the word limit.
Five to eight key words must be given below the Abstract (research papers, reviews). Words that are in the title can, and should, be among these. Very short phrases and scientific names with their common equivalents are acceptable.
All non-standard abbreviations must first appear in parentheses following their meaning written in full at first mention in the Abstract, main text and each table and figure legend. Subsequently, only abbreviations can be used.
Tables and figures
These must be self-explanatory and each presented on a separate page outside the main text, but as part of the same document. Following a concise (single-sentence), informative heading, each table should be fully understandable either through column headings or, if these are insufficient in themselves, through a footnote.
Refer to all diagrams, graphs and photographs as “Fig.”.
Present at approximately twice the size that they will appear. Ensure that, after reduction, they will be compatible with the double-column format of the journal (column width of 80 mm; maximum printed size of 226 × 170 mm).
Subdivisions of figures should be labeled with lower case, bold letters (e.g. (a), (b)) and referred to in the text in the form Fig. 1a, Fig. 1a, b. Avoid including explanatory material in the figure itself.
Present diagrams and graphs on a white background, with lines approx. 0.5 mm thick, any shading inserted as lines or dots, and symbols approx. 3 mm across. The preferred symbols, in order, are open circles, closed circles, open and closed squares, and open and closed triangles. The same symbol should be used for the same entity in different figures. The scale marks on graphs should be inside the axes. Axes should be clearly marked with units in brackets after the axis title.
With photographs, include any scale bars on the picture. Where a figure is made up of several photographs, these should be abutted unless this affects the clarity.
We need to receive your figures in electronic form. To minimise publication time of your manuscript and help you get the best printed figures it is important that all electronic artwork is supplied in the correct format and resolution. Please save vector graphics (e.g. line artwork) in EPS format at 600 dpi, and bitmap files (e.g. half-tones) in TIFF format at 300dpi.
We welcome colour figures but please note the current options available. We will then reproduce these figures in greyscale in the hardcopy, but in colour online. So if there are color figures in your paper, you can use different lines or symbols to instead of colors if necessary. But if you want to print these figures in colour, it will charge $5 for per figure.
When appropriate, a statistical treatment of data, stating what methods have been used, must be given. As a minimum, give some measure of variability, such as standard error or confidence interval, together with the mean. In presenting error bars on figures, make clear whether the bars represent one or two standard errors, or confidence limits. If necessary, present results of tests of significance, such as analysis of variance, in addition to tests of variability. After an analysis of variance, comparisons of treatment means that are restricted to specific comparisons planned before the collection of data are preferable to simultaneous tests of all treatment means. Present the number of degrees of freedom for error with all statistical analyses.
Units and symbols
The journal uses SI units wherever possible, but accepts that other units may on occasion have to be used. Products of two units must be written with a space between the units (e.g. 10 g m-2). Units derived by division must be written using the appropriate index (e.g. m s-1 (not m/s)). Note the placing of the name of a substance in, for example, 10 g mg-1 protein. Use the appropriate prefix for units and thus avoid using multipliers on axes of graphs or in headings of tables.
For volume units based either on the litre (e.g. L, mL, µL) or on the cubic metre (e.g. m3, mm, cm3, dm3) will be accepted, provided that consistent use is made of one system only.
For concentration the same applies, as well as units such as µm, mm and m.
You should add the names of ALL the authors in the list of references (unless they are really too many, for instance over 6).
For numbered references, the reference list is ordered in the order of their appearance in the paper. Citations in the text should take the following format:
GPS software receiver research has drawn more and more attention in recent years due to its numerous advantages . Many research works focus on base-band signal processing in the software receivers. In signal processing algorithm, the speed of acquisition is very important.
There are several acquisition algorithms for GPS signals introduced in recent years. These algorithms are often implemented in time domain and frequency domain. Among these algorithms, serial search acquisition is a traditional method for acquisition in CDMA system, but it is time-consuming and performed through hardware in the time domain. In contrast, the conventional circular correlation algorithm increases the speed of acquisition by transforming correlation calculation into the frequency domain through DFT calculation [2-3]……
