Weld seam recognition is the key technique in visual tracking research. Based on the weld image features, the image preprocessing and the linear feature extraction method of the weld seam recognition are designed. The extended adaptive median filtering method and modified Otsu adaptive threshold selection method for image segmentation are used in the image pre-processing process, to remove the noise and compress the image data. Through comparing with several other edge operators, the Roberts operator is chosen to achieve the goal of detecting the welding edge. Finally, the weld seam information is extracted through Hough transform and a satisfied result can be acquired. The study provides a theoretical support for the following designing of the weld tracking system. © 2015 SERSC.

computer-aided detection/diagnosis (CAD) systems are critical for doctors to understand the medical images and to improve the accuracy of detection/diagnosis of various diseases. The goal of this paper is to propose a classification framework for diagnosing different focal liver diseases based on ultrasound (US) images. Ultrasound medical imaging is one of the most common modality, which is used in diagnostic systems because of its safety and cost effectiveness. In this paper, we introduced a framework for a CAD system to diagnosing three classes of focal liver diseases, which are Cyst, Hemangioma (HEM), and Hepatocellular Carcinoma (HCC). The proposed system begins with a preprocessing step to make enhancement and noise removal of US images using a median filter. The segmentation of the liver lesions regions is done using level set method followed by the fuzzy c-mean clustering algorithm. Finally, we have used a multi-support vector machine (multi-SVM) classifier to diagnosis the classes of the focal liver diseases. By using 10-fold cross validation method, we have got an overall classification accuracy of 96.5%. Our proposed system is compared with some state of the art techniques. The experimental results show that the proposed system gives better overall accuracy than the other tested techniques.

The last six years has seen Moore's Law continue to produce incredible gains in computational power. Indeed, the November, 2007 list of the top ten fastest supercomputers in the world contained no machines with acceleration of any kind. The same list six years later has four of the ten fastest supercomputers using accelerators, including the top two machines [3] . And the ten greenest supercomputers in November 2013 are using NVIDIA GPUs [1]. This heterogeneity of processing units is present from the top of the computational power spectrum down to the bottom, where GPU hardware coupled with novel CUDA and OpenCL programming paradigms have brought significant performance gains to consumer-grade applications.

Web Laboratories (WebLabs) are essential resources for engineering education. Within this type of laboratory, a new Sharable Content Object Reference Model (SCORM) package design model is shown in this work. The proposed model is based on a set of resources that form a complete educational structure;taking into account the sequencing and navigation among the elements that compose it. In addition, it can be uploaded to a Learning Management System (LMS), offering to the students an effective tool to work with web labs. The package is structured in 4 sections or pages: Introduction, Theory, Virtual/Remote Laboratory (VRL) and Assessment;where the last performs an automated verification of the work done by the learner. In this way, one of the advantage of this methodology is that the instant results of the assessments, performed by the SCORM package, is stored in the inner LMS. Some WebLabs performing this methodology are being developed in the University of Jaén. In this work, an example is developed: 'Modelling of Dynamic System: DC Motor'. This WebLab is used in the Industrial Automation course that is included in several Industrial Engineering degrees. © 2014 IEEE.

The paper describes the steps involved in designing and implementing a mobile app for real time monitoring of mental stress using voice features and machine learning techniques. The app is easy to use and completely non-invasive. It is called StressID and it is available in the Google Play store. With the use of a server application presenting a web interface, interested parties may remotely monitor the stress states detected by the mobile app, enlarging the number of use case scenarios.

This paper shows how control techniques, such as PID or generalized predictive control, can improve the performance of TCP/IP networks when dealing with congestion. Drop tail, or more sophisticated AQM techniques such as RED, perform worse than process control techniques. A comparison between the different methods in different working scenarios is analyzed. Two different GPC controllers are evaluated. One considers the model resulting from on-line identification and the other is the linearization of the non-linear model. © 2009 EUCA.

This paper proposes a solution for solving a specific problem that requires a team of identical robots to collect in a specific order different types of resources scattered throughout an environment. A Petri net with outputs models the environment, the team possible movements and the regions with resources. An iterative solution plans the team such that each robot collects and assembles resources in the required order. Each iteration step is based on a linear programming problem that is guaranteed to return a feasible firing vector for the Petri net system. A pseudocode description of the procedure is given and a simulation example is included.

The paradigm of Petri nets offers a rich modeling power that has been successfully exploited in many different application domains as manufacturing, logistic, traffic, computer and biological domains. In order to develop and analyze Petri models in an efficient and systematic way, appropriate software tools are required. Among the existing software platforms for scientific software development, MATLAB places at the user's disposal a large set of toolboxes with an inutitive graphical interface. This paper describes some of the existing Petri net toolboxes that have been developed on MATLAB, and that cover the needs for the modeling and analysis of discrete, continuous and hybrid systems.
