The service-oriented environment offers the opportunity to create new applications, by combining existing applications offered as services, in order to react to the business' increasing pressure of quickly delivering new applications. With a large number of web services offering the same functionality, choosing the web services that meet best the client's quality of service (QoS) requirements is a very important task. We introduce a QoS-aware end to end web service composition approach that handles all the stages from the web service discovery step, to the actual binding of the services. This approach uses our method of expressing nonfunctional preferences, which requires minimal effort on the part of the clients, but offers great flexibility in managing trade-offs. We define a QoS preferences ontology and use it in our semantic web service selection to choose an initial candidate list of services for every task in the orchestration model. Then, one concrete service is chosen from each candidate list and is boand to the corresponding task. This step involves computing and comparing the aggregated QoS of the resulting composite services. The selection is performed using a genetic algorithm.

Current concerns about data privacy have lead to increased focus on data anonymization methods. Differential privacy is a new mechanism that offers formal guarantees about anonymization strength. The main challenge when using differential privacy consists in the difficulty in designing correct algorithms when operating on complex data types. One such data type is sequential data, which is used to model many actions like location or browsing history. We propose a new differential privacy algorithm for short sequence counting called Recursive Budget Allocation (RBA). We show that RBA leads to lower relative errors than current state of the art techniques. In addition, it can also be used to improve relative errors for generic differential privacy algorithms which operate on data trees.

Existing software allows the development of high quality interactive applications that permit their implementation in laboratories, both virtual and remote. To perform an experiment, the user needs to know how these applications are implemented. In addition, when coding an experiment, the user has to manage the language in which the simulation was created and needs to handle fluently a simulation language just to perform experiments. In the academic field these simulations are used to create virtual and remote laboratories. The authors propose a tool to develop automated experiments for these laboratories. It is intended that the experiments use a powerful and simple language to improve students interaction with the laboratories. That is, avoid repetitive tasks using simple algorithms, data collection and analysis of results, among other features. A new environment for the development of experiments in the authoring tool Easy Java(script) Simulations (EjsS) is proposed. It permits the decoupling of the application design phase from the experiment design. It has been equipped with a language capable of encircling all the expected commands, such as creating events, launching simultaneous applications or modifying their variables. Set with a high level layer, the language allows less experienced users to create their own experiments without having any knowledge of how the application was made. These features will be explained throughout the paper and some physic and control examples of use, as a controller for a cylindrical and a circular tank or a motion controller for a remote robot, will be given to demonstrate the potential of this new environment. © 2015, IFAC (International Federation of automatic control) Hosting by Elsevier Ltd.

For robots to be productive co-workers in the manufacturing industry, it is necessary that their human colleagues can interact with them and instruct them in a simple manner. The goal of our research is to lower the threshold for humans to instruct manipulation tasks, especially sensor-controlled assembly. In our previous work we have presented tools for high-level task instruction, while in this paper we present how these symbolic descriptions of object manipulation are translated into executable code for our hybrid industrial robot controllers. © Springer International Publishing Switzerland 2015.

In this paper, an adaptive control approach is proposed for performance of constrained robot end-effector movements in presence of uncertainty. In real-world scenarios, complex physical phenomena occuring at the place of interaction may introduce nonlinearities in the system dynamics, which have to be taken into account for proper system control. We currently propose an Extremum Seeking (ES) Model Reference Adaptive control (MRAC) approach for state tracking of multiple-input multiple-output systems which enclose nonlinearities in their dynamics and involve parametric uncertainty by employing Adaptive Dynamic Inversion (ADI). According to ADI, system nonlinearities are assumed known and are taken into account in the design of the system control law. The proposed scheme is based on MRAC and ADI while the unknown controller parameters are adapted by ES control. The system is shown to achieve global and asymptotic reference state tracking under the proposed control law by performing Lyapunov and averaging analysis. The approach is evaluated in simulation and in an experimental robot task.

This paper studies one particular aspect of providing communication security: firewall technology. This article provides a security framework in the form of packet filtering model within the firewall technology system and its components can be designed and evaluated. This paper introduces a reference model based on packet filtering firewall technology. All components are governed by a centralized security policy and they can be deployed in a distributed fashion to achieve scaling. This packet filtering firewall design is proven technology that provides confidentiality, integrity and availability in own information and network resources. The required design implement to set-up packet filtering firewall for network to protect and unauthorized access to our network. We describe the filtering process design depends on its underlying network technologies. The resulting security mechanism can be used as a bastion-host in the construction of firewall system.

Genome-Wide Association Studies (GWAS) are of great importance in identifying the genetic variants associated with traits/diseases. Due to the high number of candidate SNPs some filtering techniques are necessary to be applied. The aim of the study was to develop the comprehensive approach allowing for detailed analysis of both SNP-gene and SNP-miRNA-gene relations. We elaborated and optimized the novel signal analysis pipeline improving significantly the results of the analysis on genotype-phenotype interplay. Direct links between genotype results and gene expression levels were enriched by detailed analysis of SNP-miRNA-gene interactions at both mature miRNA structure/seed region and target binding site level. The proposed technique was applied to the data on lymphocyte radiation response and increased by almost 100% number of potential functional SNPs.

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.

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.
