A new MDA-SOA based framework for intercloud interoperability

Cloud computing has been one of the most important topics in Information Technology which aims to assure scalable and reliable on-demand services over the Internet. The expansion of the application scope of cloud services would require cooperation between clouds from different providers that have heterogeneous functionalities. This collaboration between different cloud vendors can provide better Quality of Services (QoS) at the lower price. However, current cloud systems have been developed without concerns of seamless cloud interconnection, and actually they do not support intercloud interoperability to enable collaboration between cloud service providers. Hence, the PhD work is motivated to address interoperability issue between cloud providers as a challenging research objective. This thesis proposes a new framework which supports inter-cloud interoperability in a heterogeneous computing resource cloud environment with the goal of dispatching the workload to the most effective clouds available at runtime. Analysing different methodologies that have been applied to resolve various problem scenarios related to interoperability lead us to exploit Model Driven Architecture (MDA) and Service Oriented Architecture (SOA) methods as appropriate approaches for our inter-cloud framework. Moreover, since distributing the operations in a cloud-based environment is a nondeterministic polynomial time (NP-complete) problem, a Genetic Algorithm (GA) based job scheduler proposed as a part of interoperability framework, offering workload migration with the best performance at the least cost. A new Agent Based Simulation (ABS) approach is proposed to model the inter-cloud environment with three types of agents: Cloud Subscriber agent, Cloud Provider agent, and Job agent. The ABS model is proposed to evaluate the proposed framework.

Long-term Forecasting of Frame Alignment Losses for Circuit Emulation Implementation

The article provides a method for long-term forecast of frame alignment losses based on the bit-error rate monitoring for structure-agnostic circuit emulation service over Ethernet in a mobile backhaul network. The developed method with corresponding algorithm allows to detect instants of probable frame alignment losses in a long term perspective in order to give engineering personnel extra time to take some measures aimed at losses prevention. Moreover, long-term forecast of frame alignment losses allows to make a decision about the volume of TDM data encapsulated into a circuit emulation frame in order to increase utilization of the emulated circuit. The developed long-term forecast method formalized with the corresponding algorithm is recognized as cognitive and can act as a part of network predictive monitoring system.

Turnaround across diverse global supply chains using shared metrics and change methodology: The Case of Amer Sports Corporation

Purpose - The purpose of this paper is to document the outcome of a global three-year long supply chain improvement initiative at a multi-national producer of branded sporting goods that is transforming from a holding structure to an integrated company. The case company is comprised of seven internationally well-known sport brands, which form a diverse set of independent sub-cases, on which the same supply chain metrics and change project approach was applied to improve supply chain performance. Design/methodology/approach - By using in-depth case study and statistical analysis the paper analyzes across the brands how supply chain complexity (SKU count), supply chain type (make or buy) and seasonality affect completeness and punctuality of deliveries, and inventory as the change project progresses. Findings - Results show that reduction in supply chain complexity improves delivery performance, but has no impact on inventory. Supply chain type has no impact on service level, but brands with in-house production are better in improving inventory than those with outsourced production. Non-seasonal business units improve service faster than seasonal ones, yet there is no impact on inventory. Research limitations/implications - The longitudinal data used for the analysis is biased with the general business trend, yet the rich data from different cases and three-years of data collection enables generalizations to a certain level. Practical implications - The in-depth case study serves as an example for other companies on how to initiate a supply chain improvement project across business units with tangible results. Originality/value - The seven sub-cases with their different characteristics on which the same improvement initiative was applied sets a unique ground for longitudinal analysis to study supply chain complexity, type and seasonality.

Gestiód'events : rumbo

L'objectiu principal del projecte de final de carrerà és aprendre i entendre com es desenvolupen i mantenen aplicacions en tecnologia J2EE. Ja que és una tecnologia que esta molt de moda i que utilitza la gran part del mercat de desenvolupament de programari. L'altre objectiu era desenvolupar una aplicació de gestió d'esdeveniments que permetes els usuaris enregistrarse els esdeviments i les empreses oferir i controlar l'assistència d'aquests esdeveniments.

ServEngine : Framework pel desenvolupament de serveis en línia

En aquest projecte es desenvoluparà ServEngine, un framework per al desenvolupament de serveis de portals, comunitats virtuals i sistemes de comerç electrònic basat en el patró MVC i, com s'elegirà més endavant després d'un procés d'anàlisi i comparació, utilitzant Struts com a base de desenvolupament.

Gestión académica de un centro de formación

Aquesta aplicació tindrà com a principal objectiu l'automatització de certes tasques pròpies d'un centre educatiu. S'ha escollit com a model per a l'especificació de JEE (JEE 6) el framework Open Source Jboss SIGUEM, creat per Jboss MiddelWare.

Botiga Virtual Esports Pirinencs

L'empresa Esports Pirinencs vol augmentar el seu volum de vendes amb una botiga virtual. Es vol aprofitar la mateixa aplicació per tenir un manteniment dels productes que s'ofereix als clients. Utilitzant una validació d'usuari es podrà accedir amb el rol Client o amb el rol Empleat.

Projecte BiblioUOC

Aquest treball de final de carrera consisteix en l'elaboració d'una aplicació per gestionar una botiga online de llibres. Per portar a terme aquesta aplicació s'utilitzarà Java 2Platform, Enterprise Edition (J2EE), una tecnologia que permet el desenvolupament ràpid d'aplicacions distribuïdes.

PFC : Diseño de un Framework de presentación

L'objectiu principal d'aquest PFC és el disseny i la implementació d'un nou framework de presentació per a aplicacions J2EE, com el seu títol indica, que sigui capaç de solucionar els inconvenients dels actuals frameworks del mercat que implementen aquesta funcionalitat, així com facilitar la implementació de la seva funcionalitat al desenvolupador.

Sistema de gestió del pagament de tributs (SGT)

L'objectiu d'aquest projecte és el desenvolupament d'un programari per a la gestió dels pagaments de tributs recaptats per Administracions Públiques i la posterior gestió econòmica que efectuaran les entitats recaptadores del tribut. Els tributs gestionats pel programari seran de tipus autoliquidació.

Projecte COMMusic

Construcció d'un portal Web per a COMMusic, una famosa empresa de venda de música per Internet. Aquest portal web haurà de permetre l'accés a tres tipus d'usuaris: públic en general, socis i empleats de la botiga. La implementació de tota l'aplicació, ha estat realitzada en el llenguatge Java. S'ha obtat per seguir una arquitectura J2EE, d'aquesta manera ens ha permès realitzar una aplicació robusta, escalable i altament reutilitzable.
