Revision Journal of Computer Science & Technology; vol. 13, no. 1 To support multimedia applications, it is desirable that an ad hoc network has a provision of Quality of Service (QoS). However, the provision of QoS in an ad hoc network is a challenging task due to its inherent characteristics. In this thesis, our main focus is on the provision of QoS in an ad hoc network where there can be multiple hops from a given source to a destination.

Revision Journal of Computer Science & Technology; vol. 13, no. 1; http://sedici.unlp.edu.ar/handle/10915/4215 The general objective of this thesis is the development of an adaptive technique for extracting knowledge in large databases. Nowadays, technology allows storing huge volumes of information. For this reason, the availability of techniques that allow, as a first stage, analyzing that information and obtaining knowledge that can be expressed as classification rules, is of interest. However, the information available is expected to change and/or increase with time, and therefore, as a second stage, it would be relevant to adapt the knowledge acquired to the changes or variations affecting the original data set. The contribution of this thesis is focused on the definition of an adaptive technique that allows extracting knowledge from large databases using a dynamic model that can adapt to information changes, thus obtaining a data mining technique that can generate useful knowledge and produce results that the end user can exploit. The results of this research work can be applied to areas such as soil analysis, genetic analysis, biology, robotics, economy, medicine, plant failure detection, and mobile systems communications. In these cases, obtaining an optimal result is important, since this helps improve the quality of the decisions made after the process.

Articulo Journal of Computer Science & Technology; vol. 13, no. 1 We present here the first visual interface for a Mexican Spanish Sign Language translator on its first development stage: sign-writing recognition. The software was developed for the unique characteristics of Mexican linguistics and was designed in order to use sentences or a sequence of signs in sign-writing system which are decoded by the program and converted into a series of images with movement that correspond to the Mexican sign language system. Using a lexical, syntactic and semantic algorithms plus free software such as APIs's from Java, video converter software, data base manager like MySQL, Postgres and SQlite, was possible to read and interpret the rich and complex Mexican language. Our application for visual interface showed to be capable of reading and reconstruct each sentence used for the interpreter and translate it into a high de finition video. The average time of video display vs number of sentences to interpret, probed to be in linear relation with an average time of two seconds per sentence. The software has over come the problem of homonym words frequently used in Spanish language and verb tense relation for each sentence, special symbols such as #, %, $, etc. are still not recognized into the software

Articulo Journal of Computer Science & Technology; vol. 13, no. 1 Internet world is characterized by many users among which are crackers and thieves. Hence, the need for a secured system to safely exchange confidential information among users across the web is required. Of such tool is steganography that simply hides the user information under other kind of information such as image so that no one suspects that a sensitive data is being transferred. This paper presents a steganography scheme with an improved capacity and enhanced security by compressing the information before embedding it under an image. This is done by encoding the message before embedding it in the blue object of the cover image components (pixels). To prove this scheme, several testing are performed and results are compared.

Articulo Journal of Computer Science & Technology; vol. 13, no. 1 This document presents a quantitative analysis of the direct and relative throughput of IEEE 802.11e. The global throughput of an 802.11e WLAN is determined by EDCA (Enhanced Distributed Channel Access) parameters, among other aspects, that are usually configured with predetermined and static values. This study carefully evaluates the Quality of Service (QoS) of Wi-Fi with EDCA in several realistic scenarios with noise and a blend of wireless traffic (e.g., voice, video, and best effort, with Pareto distribution). The metrics of the benefits obtained in each case are compared, and the differentiated impact of network dynamics on each case is quantified. The results obtained show that the default settings are not optimal, and that with an appropriate selection, can be achieved improvements of the order of 25 %, according to the type of traffic. In addition, it could be shown the quantitative impact of each parameter EDCA on the overall performance. This study proposes a new experimental scenario based on the relative proportion of traffic present in the network. Stations have been simulated using the Möbius tool, which supports an extension of SPN (Stochastic Petri Networks), known as HSAN (Hierarchical Stochastic Activity Networks).

Articulo Journal of Computer Science & Technology; vol. 13, no. 1 Fading and obstacles constitute major threats to effective quality of service (QoS) delivery in wireless local area network (WLAN) environments. In this contribution, we investigate the signal quality of indoor and outdoor WLANs over a defined coverage area. We present experimental analysis of case studies that will be useful for further research and validate the system’s performance in practice. Using an optimized form of the pathloss models, a simulation of the system is carried out over short and extended coverage. Simulation results show that signal quality could be effectively managed to improve the system’s performance for both indoor and outdoor environments in the presence of fading and other environmental factors.

Revision Journal of Computer Science & Technology; vol. 12, no. 3 Many refactorings are simple but tedious, which makes them good candidates for automation. Common refactorings include renaming identifiers, moving code between classes or functions, and encapsulating variables. Most integrated development environments (IDEs) – including Eclipse, IntelliJ IDEA, Microsoft Visual Studio, and Apple Xcode – provide support for automated refactoring. These features allow the programmer to select a portion of the source code and select a particular refactoring to apply. The IDE then performs a static analysis of the source code, determining whether the desired change will change its behavior. If the behavior will not change, the IDE modifies the source code, showing the user a side-by-side, before-andafter view of the source code so that he can visually inspect the changes

Articulo Journal of Computer Science & Technology; vol. 12, no. 3 This study proposes the use of abstract software models in order to meet the diversity of embedded platforms. A UML 2.0 Profile for Modeling Application and Platform of Embedded Software (called PROAPES) is proposed. Such profile is intended to generically describe the services provided by a system platform that makes use of an RTOS. In addition, this study presents a Model Transformation (MT) based on the PROAPES profile, named MT-PROAPES. In this way, MT-PROAPES uses a Platform Model (PM), created on the basis of the proposed profile (PROAPES), and performs a transformation named Platform Independent Model (PIM)-behavior into Platform Specific Model (PSM)-behavior. Thus, the generation of reusable model transformations that are adaptable to different platform models is possible

Articulo Journal of Computer Science & Technology; vol. 12, no. 3 In this paper a fully automatic scheme for embedding visually recognizable watermark patterns to video objects is proposed. The architecture consists of 3 main modules. During the first module unsupervised video object extraction is performed, by analyzing stereoscopic pairs of frames. In the second module each video object is decomposed into three levels with ten subbands, using the Shape Adaptive Discrete Wavelet Transform (SA-DWT) and three pairs of subbands are formed (HL₃ , HL₂), (LH₃, LH₂) and (HH₃, HH₂). Next Qualified Significant Wavelet Trees (QSWTs) are estimated for the specific pair of subbands with the highest energy content. QSWTs are derived from the Embedded Zerotree Wavelet (EZW) algorithm and they are high-energy paths of wavelet coefficients. Finally during the third module, visually recognizable watermark patterns are redundantly embedded to the coefficients of the highest energy QSWTs and the inverse SA-DWT is applied to provide the watermarked video object. Performance of the proposed video object watermarking system is tested under various signal distortions such as JPEG lossy compression, sharpening, blurring and adding different types of noise. Furthermore the case of transmission losses for the watermarked video objects is also investigated. Experimental results on real life video objects indicate the efficiency and robustness of the proposed scheme

Articulo Journal of Computer Science & Technology; vol. 12, no. 3 Reuse-oriented software methodologies have emerged to provide a set of rules or guides for development and evolution of software systems by reusing existing domain engineering artefacts such as requirements, architecture, components, test cases, etc. Domain engineering methods, such as software product lines engineering, aim at reducing development time, effort, cost, and complexity by taking advantage of the commonality within a portfolio of similar products. However, these methodologies are not based on specific domains, instead they cover a wide range of domains without considering particularities within them. Therefore, in this work we define a novel approach in which the creation of a software product line is guided by a subdomain analysis process, oriented to a particular case within the marine ecology domain. The methodology is then applied to a specific organization in order to create a product of the line.

It was developed in the Netconf working group and published in December 2006 as RFC 4741 and later revised in June 2011 (RFC 6241). This protocol defines a simple mechanism through which a network device can be managed, configuration data information can be retrieved, and new configuration data can be uploaded and manipulated. The protocol allows the device to expose a full and formal application programming interface (API). Applications can use this straightforward API to send and receive full and partial configuration data sets.
