Pervasive Computing Applications using Different Computational Platforms

This paper provides an insight into the concept of computing and their applications. Different computational boards are available in the market for the development of a smart device. Many applications can be developed for the ease of the society. These devices provide great computing functions with mobility too and are smart enough to sense the surroundings. The paper will enlighten some of the important features of the computational platforms and three different applications using them depending on their functionalitie

Structural analysis of the pymedeas integrated assessment model

Treballs Finals de Grau de Física, Facultat de Física, Universitat de Barcelona, Curs: 2022, Tutors: Jordi Solé, Joan BechIntegrated assessment models (IAMs) simulate the coupled behaviour of socioeconomic and natural systems and are used to assess climate and energy policies. Here, the inner structure of pymedeas, an open-source IAM, is visualized and analysed using GraphPySD, a new Python package developed for this project. The results of the study allow to better understand the model and open future directions to improve its design, performance, and functionalitie

Assessing the potential of ubiquitous computing for improving business process performance

Although ubiquitous technologies such as RFID, sensor networks, and networked embedded systems are quite mature, widespread adoption by organizations has yet to take place. This may be due to the lack of systematic assessment of the potential of ubiquitous technologies for creating value. Accordingly, a prescriptive model is presented that shows how value is created through the fit between generic capabilities of ubiquitous technologies and task characteristics in business processes. The identified task characteristics can thus be used as indicators for assessing the potential improvements in business process performance through particular ubiquitous computing functionalitie

The RISCOSS platform for risk management in open source software adoption

Managing risks related to OSS adoption is a must for organizations that need to smoothly integrate OSS-related practices in their development processes. Adequate tool support may pave the road to effective risk management and ensure the sustainability of such activity. In this paper, we present the RISCOSS platform for managing risks in OSS adoption. RISCOSS builds upon a highly configurable data model that allows customization to several types of scopes. It implements two different working modes: exploration, where the impact of decisions may be assessed before making them; and continuous assessment, where risk variables (and their possible consequences on business goals) are continuously monitored and reported to decision-makers. The blackboard-oriented architecture of the platform defines several interfaces for the identified techniques, allowing new techniques to be plugged in.Peer ReviewedPostprint (author’s final draft

Statistique et Big Data Analytics; Volumétrie, L'Attaque des Clones

This article assumes acquired the skills and expertise of a statistician in unsupervised (NMF, k-means, SVD) and supervised learning (regression, CART, random forest). What skills and knowledge do a statistician must acquire to reach the "Volume" scale of big data? After a quick overview of the different strategies available and especially of those imposed by Hadoop, the algorithms of some available learning methods are outlined in order to understand how they are adapted to the strong stresses of the Map-Reduce functionalitie

Using actor networks in decision making during content-packaging development

In order to integrate sustainability in the development of content-packaging combinations, the consequences of decisions for the entire life cycle need to be analyzed in early stages of the development process. To adequately underpin these decisions, several aspects, for example the economic and the environmental impact, need to be assessed. A so-called actor network is developed to support designers in decision making. This publication examines practical use situations of this actor network tool based on information from research partners. Scenarios are written in order to depict requirements for the actor network tool, considering different users and functionalitie

Design and Implementation of a Virtual Team Collaboration System

This paper analyzes a newly developed virtual team collaboration site and compares this application with the currently in use team collaboration tool created using a Google site. Various tests that are essential for a web service to function properly are performed to compare the applications. The tests are aimed to find any issues with the applications and identify if Teamboard ODU, the newly developed application, can perform better than the Google site. We test for speed, performance, usability, functionality and also explore the methodology used to develop the application. These test results allow us to make an informed assumption about the effectiveness of Teamboard ODU and help us understand whether this can be a replacement for the Google site. The study hypothesizes that Teamboard ODU performs better in terms of the HTTP transaction, site availability and load time. It also has functionalities comparable to the Google site. Future enhancement and maintenance can also be performed if needed. Several scenarios are developed to test the hypotheses, and the results will be used to compare the two sites and identify whether Teamboard ODU can be an effective replacement

Magnetoplasmonics: Combining Magnetic and Plasmonic Functionalities

Comunicación presentada en el 3rd European Workshop on Self Organized Nanomagnets, celebrado en Guadarrama del 16 al 20 de abril de 2012.Nanosystems with combined magnetic and plasmonic functionalities have in recent years become an active topic of research. In these new stn-lctures, know as magneto-plasmonics, magnetic and plasmonic properties are interlwined, allowing for example plasmonic properties to become tunable upon de application of a magnetic field (active plasmonics), or the Magneto*Optical (MO) effects to be largely increased by plasmon resonance excitation, as a consequence of the enhancement of the electromagnetic (EM) field in the MO active component of the structure. ln this last case, the study of the enhanced MO activity in structures with subwavelength dimensions is especially interesting since they may be viewed as nanoantennas in the visible range with MO functionalities. The light harvesting properties of these systems upon plasmon resonance excitation bring as a consequence an enhanced EM field in its interior, and more interestingly in the region where the MO active component is present. At this stage, optimizing the EM field distribution within the structure by maximizing it in the MO components region while simultaneously minimizingit in all the other, non MO active, lossy components, will allow for the development of novel systems with even larger MO activity with reduced optical losses .Peer Reviewe

Conception of a simulator for a TEL system in orthopaedic surgery.

Within a research project whose aim is to promote the learning of percutaneous operation in orthopedic surgery, we investigate some representation models of empirical, deductive, and perceptivo-gestural knowledge. From these models, we design an TEL system (Tecnological Enhaced Learning) This project belongs to a multidisciplinary field including computer, orthopedic surgery, medical imaging, didactic and cognitive sciences. The article presents the design principles of TEL with a particular interest in the development of a simulator. This simulator allows a virtual exercise interacting with the learner in visual, temporal and haptic dimension
