A Two Layered Model for Evolving Web Resources

In this paper the key features of a two-layered model for describing the semantic of dynamical web resources are introduced. In the current Semantic Web proposal [Berners-Lee et al., 2001] web resources are classified into static ontologies which describes the semantic network of their inter-relationships [Kalianpur, 2001][Handschuh & Staab, 2002] and complex constraints described by logical quantified formula [Boley et al., 2001][McGuinnes & van Harmelen, 2004][McGuinnes et al., 2004], the basic idea is that software agents can use techniques of automatic reasoning in order to relate resources and to support sophisticated web application. On the other hand, web resources are also characterized by their dynamical aspects, which are not adequately addressed by current web models. Resources on the web are dynamical since, in the minimal case, they can appear or disappear from the web and their content is upgraded. In addition, resources can traverse different states, which characterized the resource life-cycle, each resource state corresponding to different possible uses of the resource. Finally most resources are timed, i.e. they information they provide make sense only if contextualised with respect to time, and their validity and accuracy is greatly bounded by time. Temporal projection and deduction based on dynamical and time constraints of the resources can be made and exploited by software agents [Hendler, 2001] in order to make previsions about the availability and the state of a resource, for deciding when consulting the resource itself or in order to deliberately induce a resource state change for reaching some agent goal, such as in the automated planning framework [Fikes & Nilsson, 1971][Bacchus & Kabanza,1998].

Modular Digital Watermarking for Image Verification and Secure Data Storage in Web Applications

Our modular approach to data hiding is an innovative concept in the data hiding research field. It enables the creation of modular digital watermarking methods that have extendable features and are designed for use in web applications. The methods consist of two types of modules – a basic module and an application-specific module. The basic module mainly provides features which are connected with the specific image format. As JPEG is a preferred image format on the Internet, we have put a focus on the achievement of a robust and error-free embedding and retrieval of the embedded data in JPEG images. The application-specific modules are adaptable to user requirements in the concrete web application. The experimental results of the modular data watermarking are very promising. They indicate excellent image quality, satisfactory size of the embedded data and perfect robustness against JPEG transformations with prespecified compression ratios.

A Review of the Effects of Altered Hydrology and Salinity on Vertebrate Fauna and Their Habitats in Northeastern Florida Bay

Estuarine productivity is highly dependent on the freshwater sources of the estuary. In Florida Bay, Taylor Slough was historically the main source of fresh water. Beginning in about 1960, and culminating with the completion of the South Dade Conveyance System in 1984, water management practice began to change the quantity and distribution of flow from Taylor Slough into Northeastern Florida Bay. These practices altered salinity and hydrologic parameters that had measurable negative impacts on vertebrate fauna and their habitats. Here, I review those impacts from published and unpublished literature and anecdotal observations. Almost all vertebrates covered in this review have shown some form of population decline since 1984; most of the studies implicate declines in food resources as the main stressor on their populations. My conclusion is that the diversion of fresh water resulted in an ecological cascade starting with hydrologic stresses on primary then secondary producers culminating in population declines at the top of the food web.

Eyetracking: analisi della user interface di una pagina web

Negli ultimi vent'anni con lo sviluppo di Internet, il modo di comunicare tra le persone �è totalmente cambiato. Grazie a Internet si sono ridotte le distanze e soprattutto tramite i siti web le aziende hanno una propria vetrina sul mondo sempre accessibile. Tutto ci�ò ha portato a nuovi comportamenti da parte dei consumatori che divengono sempre pi�u esigenti nella vastità di informazioni presenti sul Web. Perciò è necessario che le web companies riescano a produrre website efficienti e usabili per favorire l'interazione con l'utente. Inoltre il web ha avuto una rapida espansione per quanto concerne le metodologie di sviluppo e analisi del comportamento del consumatore. Si cercano sempre nuovi spunti per poter acquisire quello che �è il percorso di un utente affinché porti a termine una determinata azione nel proprio dominio. Per questo motivo, oltre agli strumenti gi�à consolidati come il riempimento di questionari o il tracking per mezzo di piattaforme come Google Analytics, si �è pensato di andare oltre e cercare di analizzare ancora pi�u a fondo il "consumAttore". Grazie ad un eye-tracker �è possibile riconoscere quelli che sono i modelli cognitivi che riguardano il percorso di ricerca, valutazione e acquisto di un prodotto o una call to action, e come i contenuti di una web application influenzano l'attenzione e la user experience. Pertanto l'obiettivo che si pone questo studio �è quello di poter misurare l'engagement della navigazione utente di una web application e, nel caso fosse necessario, ottimizzare i contenuti al suo interno. Per il rilevamento delle informazioni necessarie durante l'esperimento, mi sono servito di uno strumento a supporto delle decisioni, ovvero un eye-tracker e della successiva somministrazione di questionari.

Design of an information system for metrology contents

Dimensional and form inspections are key to the manufacturing and assembly of products. Product verification can involve a number of different measuring instruments operated using their dedicated software. Typically, each of these instruments with their associated software is more suitable for the verification of a pre-specified quality characteristic of the product than others. The number of different systems and software applications to perform a complete measurement of products and assemblies within a manufacturing organisation is therefore expected to be large. This number becomes even larger as advances in measurement technologies are made. The idea of a universal software application for any instrument still appears to be only a theoretical possibility. A need for information integration is apparent. In this paper, a design of an information system to consistently manage (store, search, retrieve, search, secure) measurement results from various instruments and software applications is introduced. Two of the main ideas underlying the proposed system include abstracting structures and formats of measurement files from the data so that complexity and compatibility between different approaches to measurement data modelling is avoided. Secondly, the information within a file is enriched with meta-information to facilitate its consistent storage and retrieval. To demonstrate the designed information system, a web application is implemented. © Springer-Verlag Berlin Heidelberg 2010.

React vs Angular : Slaget om användarupplevelsen

Lately, various programming frameworks has been developed for developing web applications. These frameworks focus on increasing the user experience by performance improvements such as faster render times and response times. One of these frameworks are React, which has introduced a completely new architectural pattern for both managing the state and data flow of an application. React also offers support for native application development and makes server-side rendering possible. Something that is difficult to accomplish with an application developed with Angular 1.5, which is used by the company Dewire today. The aim of this thesis was to compare React with an existing Angular project, in order to determine whether React could be a potential replacement for Angular. To gain knowledge about the subject, a theoretical study of web- based sources has been made. While the practical part has been to rebuild a web application with React together with the architecture Flux, which is based on a view from the Angular project. The implementation process was repeated until the view was completed and a desired data flow, as in the Angular application, was reached. The resulting React application was later compared with the Angular application developed by the company, where the outcome of the comparison showed that the React performed better than Angular in all tests. In conclusion, due to the timeframe of the project, only the most important parts of the Angular project were implemented in order to carry out the measurements that were of interest to the company. By recreating most of the functionality, or the entire Angular application, more interesting comparisons could have been done.

Applied web traffic analysis for numerical encoding of SQL Injection attack features.

SQL Injection Attack (SQLIA) remains a technique used by a computer network intruder to pilfer an organisation’s confidential data. This is done by an intruder re-crafting web form’s input and query strings used in web requests with malicious intent to compromise the security of an organisation’s confidential data stored at the back-end database. The database is the most valuable data source, and thus, intruders are unrelenting in constantly evolving new techniques to bypass the signature’s solutions currently provided in Web Application Firewalls (WAF) to mitigate SQLIA. There is therefore a need for an automated scalable methodology in the pre-processing of SQLIA features fit for a supervised learning model. However, obtaining a ready-made scalable dataset that is feature engineered with numerical attributes dataset items to train Artificial Neural Network (ANN) and Machine Leaning (ML) models is a known issue in applying artificial intelligence to effectively address ever evolving novel SQLIA signatures. This proposed approach applies numerical attributes encoding ontology to encode features (both legitimate web requests and SQLIA) to numerical data items as to extract scalable dataset for input to a supervised learning model in moving towards a ML SQLIA detection and prevention model. In numerical attributes encoding of features, the proposed model explores a hybrid of static and dynamic pattern matching by implementing a Non-Deterministic Finite Automaton (NFA). This combined with proxy and SQL parser Application Programming Interface (API) to intercept and parse web requests in transition to the back-end database. In developing a solution to address SQLIA, this model allows processed web requests at the proxy deemed to contain injected query string to be excluded from reaching the target back-end database. This paper is intended for evaluating the performance metrics of a dataset obtained by numerical encoding of features ontology in Microsoft Azure Machine Learning (MAML) studio using Two-Class Support Vector Machines (TCSVM) binary classifier. This methodology then forms the subject of the empirical evaluation.

2 D game ediror on-line : A edição de videojogos em contexto web

Descreve-se, no presente trabalho, os esforços envidados no sentido de criar uma solução informática generalista, para os problemas mais recorrentes do processo de produção de videojogos 20, baseados em sprites, a correr em plataformas móveis. O sistema desenvolvido é uma aplicação web que está inserida no paradigma cloud­computing, usufruindo, portanto, de todas as vantagens em termos de acessibilidade, segurança da informação e manutenção que este paradigma oferece actualmente. Além das questões funcionais, a aplicação é ainda explorada do ponto de vista da arquitetura da implementação, com vista a garantir um sistema com implementação escalável, adaptável e de fácil manutenção. Propõe-se ainda um algoritmo que foi desenvolvido para resolver o problema de obter uma distribuição espacial otimizada de várias áreas retangulares, sem sobreposições nem restrições a nível das dimensões, quer do arranjo final, quer das áreas arranjadas. ABSTRACT: This document describes the efforts taken to create a generic computing solution for the most recurrent problems found in the production of two dimensional, sprite­based videogames, running on mobile platforms. The developed system is a web application that fits within the scope of the recent cloud-computing paradigm and, therefore, enjoys all of its advantages in terms of data safety, accessibility and application maintainability. In addition, to the functional issues, the system is also studied in terms of its internal software architecture, since it was planned and implemented in the perspective of attaining an easy to maintain application, that is both scalable and adaptable. Furthermore, it is also proposed an algorithm that aims to find an optimized solution to the space distribution problem of several rectangular areas, with no overlapping and no dimensinal restrictions, neither on the final arrangement nor on the arranged areas.

Proton Form Factor Puzzle and the CEBAF Large Acceptance Spectrometer(CLAS) Two-Photon Exchange Experiment

The electromagnetic form factors are the most fundamental observables that encode information about the internal structure of the nucleon. The electric ($G_{E}$) and the magnetic ($G_{M}$) form factors contain information about the spatial distribution of the charge and magnetization inside the nucleon. A significant discrepancy exists between the Rosenbluth and the polarization transfer measurements of the electromagnetic form factors of the proton. One possible explanation for the discrepancy is the contributions of two-photon exchange (TPE) effects. Theoretical calculations estimating the magnitude of the TPE effect are highly model dependent, and limited experimental evidence for such effects exists. Experimentally, the TPE effect can be measured by comparing the ratio of positron-proton elastic scattering cross section to that of the electron-proton $\large(R = \frac{\sigma (e^{+}p)}{\sigma (e^{-}p)}\large)$. The ratio $R$ was measured over a wide range of kinematics, utilizing a 5.6 GeV primary electron beam produced by the Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab. This dissertation explored dependence of $R$ on kinematic variables such as squared four-momentum transfer ($Q^{2}$) and the virtual photon polarization parameter ($\varepsilon$). A mixed electron-positron beam was produced from the primary electron beam in experimental Hall B. The mixed beam was scattered from a liquid hydrogen (LH$_{2}$) target. Both the scattered lepton and the recoil proton were detected by the CEBAF Large Acceptance Spectrometer (CLAS). The elastic events were then identified by using elastic scattering kinematics. This work extracted the $Q^{2}$ dependence of $R$ at high $\varepsilon$ ($\varepsilon > $ 0.8) and the $\varepsilon$ dependence of $R$ at $\langle Q^{2} \rangle \approx 0.85$ GeV$^{2}$. In these kinematics, our data confirm the validity of the hadronic calculations of the TPE effect by Blunden, Melnitchouk, and Tjon. This hadronic TPE effect, with additional corrections contributed by higher excitations of the intermediate state nucleon, largely reconciles the Rosenbluth and the polarization transfer measurements of the electromagnetic form factors.

VALORACIÓN ECONÓMICA DE LOS RECURSOS HÍDRICOS EN LAS CUENCAS DE LOS RÍOS BANANO Y BANANITO

Entre los meses de marzo y setiembre del 2004, el Centro Internacional en Política Económica para el Desarrollo Sostenible de la Universidad Nacional (CINPE-UNA) elaboró el estudio Valoración económica de los recursos hI’dricos en las cuencas de los rfos Banano y Bananito3 . El objetivo general de éste responde a “estimar el valor del recurso hídrico en las cuencas de los ríos Banano y Bananito, en función de los usos prioritarios, para la recomendación de mecanismos efectivos para la sostenibilidad de un sistema de compensación por los servicios hidrológicos”. Para cumplir con este objetivo se plantean los siguientes objetivos específicos: (1) identificar el método de valoración económica para el recurso hídrico más apropiado dadas las condiciones de la zona, (2) cuantificar los servicios hidrológicos en las cuencas de los ríos Banano y Bananito en función de los principales usos, y (3) recomendar un mecanismo de pago voluntario por el servicio ambiental hídrico, basado en los resultados del estudio, que provea al Área de Conservación La Amistad Caribe (ACLA-C) los elementos para el desarrollo de una experiencia concreta.Producto de una exhaustiva revisión bibliográfica y dados los objetivos del estudio se seleccionó el Análisis de Múltiples Criterios (AMC), como la metodología marco para la valoración económica. Esto implica la aplicación de un método no tradicional, que permite combinar variables cuantitativas y cualitativas. A este respecto, el uso de una metodología participativa y multisectorial hizo posible la participación de los principales grupos de actores usuarios del agua. que se clasificaron en cinco grupos: (1) Asociaciones Administradoras de Acueductos Rurales (ASADAS) y acueductos rurales, (2) ONG’s y organizaciones comunales, (3) sociedad civil, (4) empresa privada y (5) sector público.Luego de sistematizar la información recabada durante las 23 sesiones de consulta participativa. se procede al análisis de los datos, que sirven de insumos para realizar la valoración económica y, finalmente, el diseño de la propuesta de mecanismos de cobro por grupo de usuarios para el pago por servicios ambientales. Los resultados finales se presentan mediante el uso de matrices y gráficos de telaraña.Este informe presenta los avances correspondientes al primer objetivo específico. Asimismo, incluye los comentarios y las sugerencias realizadas durante y posterior al taller de discusión con representantes de PROARCA-APM, TNC y ACLA-C. El documento contiene la caracterización económica y social del área en estudio, una revisión de estudios de valoración, y métodos, así como el método de valoración seleccionado y su forma de aplicación.A bstract:Between March and September 2004, the International Center of Economic Policy for Sustainable Development of the National University (CINPE.IJNA) elaborated the study Economic Valuation of ihe Water Resources in ihe Basins of ihe rivers Banano and Bananito4. The general objcctive of it answers to “estimate the value of the water resource in the basin of the rivers Banano and Bananito, depending on the prior uses, for the recommendation of effective mechanisms for the sustainability of a system of compensation for the hydrological serv ices”.The following specific objectives appear to reach the general objective: (1) To identify the most appropriate method of economic valuation for water resource given (he conditions of the zone. (2) To quantify the hydrological services in the basins of the rivers Banano and Bananito depending on (he principal uses. And (3) to recommend a mechanism of voluntary payment for the environmental water service based on the results of the study, which provides to La Amistad Caribe Conservation Area (ACLA-C), the elements for the development of a concrete experience.Product and given of an exhaustive bibliographical review, the Analysis of Multiple Criteria (AMC) is selected as (he methodology for the economic valuation. It implies (he application of a not traditional method, which allows combining quantitative and qualitative variables. In this regard, the use of a participatory methodoiogy there made possible the participation of the principal groups of actors users of the water, who quatified ¡n five groups to knowing, (1) administrative associations of rural aqueducts (ASADAS), (2) ONG and communal organizations, (3) civil society, (4) private sector and (5) public sector.After systematizing the information obtained during 23 meetings of participatory consultation. one proceeds to the analysis of the information, which use as ¡nputs to realize the economic valuation. Finally, the design of the offer of collection mechanisms for user group for the payment for environmental services is presented. The final results appear by means of the use of counterfoils and spider web graphs.This repon includes the commentaries and suggestions realized during and later to ihe workshop of discussion with representatives of PROARCA-APM, TNC and ACLA-C. The document also contains the economic and social characterization of the area under study, a review of studies of valuation, and methods. as well as the method of valuation selected and its form of application.
