Full textBlockchain ser ut att vara den nya teknologin som leder till stora förändringar i olika industrier i form av decentralisering. En grupp av noder kan till slut organisera sig och arbeta tillsammmans utan en central figur som styr och har kontroll över arbetet. Utöver decentralisering ger blockchain också fördelen av uthållighet, oföränderlighet och säkerhet till systemet tack vare sin kryptografiska grund. I den här studien utnyttjar vi privat blockchainteknologi för att ta steg mot en decentraliserad service level agreement (SLA) platform, där både tjänsteleverantörer och konsumenter saknar makten att manipulera kontrakt och dess resultat. Studien ger en systematisk literaturstudie på state-of-the-art inom SLA och relevant blockchain teknologi, ett bevis på koncept som fungerar tillsammans med Ericssons decentraliserade Nubo Service Marknad, och till slut en simulation som undersöker hur systemet reagerar i form av genomströmmning och responstid under olika nätverksbelastningar. Undersökningen visar att nätverket fungerar som förväntat upp till 70 transaktioner per sekund, då nätverket begränsas av genomströmning och köer bildas.

Este trabalho versa sobre o funk carioca, encarado como manifestação do hip hop contemporâneo. Para compreender esse movimento, propõe-se a analisar as letras do SLA Funk de Fernanda Abreu (FA) por meio da isotopia da busca por um pertencimento. Revelam-se, no desenvolvimento dessa procura, três componentes: o baile, caracterizado como rito dionisíaco; a antropofagia; e a metalinguagem. Os cronótopos do encontro e do carnaval, bem como a intertextualidade, compõem as canções de FA e caracterizam a relação sujeito-espaço-tempo nelas existente. Para atingir seu objetivo, a pesquisa fundamenta-se, principalmente, nas noções bakhtinianas de diálogo, carnavalização e cronótopo. Os resultados mostram que o tema de constituição das canções analisadas é o prazer realizado nos bailes da pesada. Os sujeitos das canções de FA tentam explicitar, metalingüisticamente, o caráter carnavalesco do baile funk. No universo do hip hop carioca das canções de FA, o corpo aparece retratado como fonte de poder que constitui as mais diversas relações entre os sujeitos. As SLAs representam a cultura do funk por manterem, em seus enunciados, um elo entre discursos e realidade, ao retratarem o baile e seu culto à diversão e ao prazer. Este, adquirido por meio do movimento (suingue) do corpo que dança, canta e encanta. No embalo dos ouvidos e dos movimentos dos corpos, as canções acabam por sustentar e promover um universo da cultura funk: um mundo composto pela liberação do prazer carnal. Assim, as canções de FA levam a conhecer o universo do funk carioca por manifestarem, em seus enunciados, um modo de ser e de sentir.
This research runs upon carioca funk, known as a manifestation of contemporary hip hop. To understand this movement, we would analyze the lyrics of SLA Funk by Fernanda Abreu (FA) through the isotopy of a social belonging search. Three components are revealed during this search: the ball, characterized as a Dionysian ritual; the anthropophagy, and melalanguage. The chronotopes of the meeting and the carnival, as well as the intertextuality, compose FA's songs and characterize the existing relation among subject, space and time. To achieve its objective, the research is, mainly, based on Bakhtinian notions of dialogue, carnavalization and chronotope. The results show that the constitution theme of the analyzed songs is the pleasure realized in Heavy Balls. The subjects of FA's songs try to make explicit, metalinguistically, the carnival character of a funk ball. In the universe of carioca hip hop FA's songs, the body is portrayed as the source of power that constitutes the most diverse relations among subjects. The SLAs represent the culture of funk by maintaining in its statements, a link between discourse and reality, as they portray the ball and its worship to amusement and pleasure, acquired by the movement (swing) of the body that dances, sings and enchants. In the rocking of ears and the bodies' movement, the songs support and promote a universe of funk culture: a world composed of the liberation of carnal pleasure. So, FA's songs reveal the universe of carioca funk by expressing, in its statements, a way of being and of feeling.

Engenharia de Software Baseada em Componentes (CBSE) e Arquitetura Orientada a Servi?os (SOA) tornaram-se formas populares de se desenvolver software nos ?ltimos anos. Durante o ciclo de vida de um software, v?rios componentes e servi?os podem ser desenvolvidos, evolu?dos e substitu?dos. Em ambientes de produ??o, a substitui??o de componentes essenciais - como os que envolvem bancos de dados - ? uma opera??o delicada, onde v?rias restri??es e stakeholders devem ser considerados. Service-Level agreement (acordo de n?vel de servi?o - SLA), de acordo com o gloss?rio oficial da ITIL v3 , ? ?um acordo entre um provedor de servi?o de TI e um cliente. O acordo consiste em um conjunto de restri??es mensur?veis que um prestador de servi?os deve garantir aos seus clientes.?. Em termos pr?ticos, um SLA ? um documento que um prestador de servi?o oferece aos seus consumidores garantindo n?veis m?nimos de qualidade de servi?o (QoS). Este trabalho busca avaliar a utiliza??o de SLAs para guiar o processo de transi??o de bancos de dados em ambientes de produ??o. Em particular, propomos um conjunto de guidelines baseados em SLAs para apoiar decis?es migra??es de bancos de dados relacionais (RDBMS) para bancos NoSQL. Nosso trabalho ? validado por estudos de caso.
Component-based Software Engineering (CBSE) and Service-Oriented Architecture (SOA) became popular ways to develop software over the last years. During the life-cycle of a software system, several components and services can be developed, evolved and replaced. In production environments, the replacement of core components, such as databases, is often a risky and delicate operation, where several factors and stakeholders should be considered. Service Level Agreement (SLA), according to ITILv3?s official glossary, is ?an agreement between an IT service provider and a customer. The agreement consists on a set of measurable constraints that a service provider must guarantee to its customers.?. In practical terms, SLA is a document that a service provider delivers to its consumers with minimum quality of service (QoS) metrics.This work is intended to assesses and improve the use of SLAs to guide the transitioning process of databases on production environments. In particular, in this work we propose SLA-Based Guidelines/Process to support migrations from a relational database management system (RDBMS) to a NoSQL one. Our study is validated by case studies.

Full textWith Cloud Computing becoming a popular term on the Information Technology (IT) market, security and accountability has become important issues to highlight. In our research we review these concepts by focusing on security risks with Cloud Computing and the associated services; Software, Platform and Infrastructure (SPI) and connecting them with a social study of trust.
The method that was conducted during our research was reviewing secondary literature, interviewing different experts regarding Cloud Computing and relating standards already established by ENISA, NIST, and CSA to the interviews.
The result of this study shows connections between the specific SPIs, both how they compare, but also how they differ. In the end we were also able to rank the top security risks from interviews with experts and see which SPI could be the most insecure one and what countermeasures could be applied.
This was further related to trust and Service Level Agreement (SLA) in Cloud Computing to show how the security risks we discuss are related to these two specific areas. By highlighting this we wanted to present useable information for both clients and providers in how to create a better Cloud Computing environment.

The target is then to avoid the "build it first, manage it later" paradigm. The research questions targeted by the PhD are the following: 1. Identify the changes on Network Operation Support Systems implementation when using SDN as a design approach for future networks. The study could be restricted to mobile networks for example, or sub-part of it (CORE networks, RAN, data centers, etc); 2.Identify the needed evolution at the management interfaces level: a. Shall we need alternative to the well-known FCAPS and do we still need the element management system? b. What will change to provision an SDN based service? c. How to ensure resiliency of SDN based networks?

Full textThe cloud computing paradigm given its service and deployment models presents several benefits and challenges. One of the main challenges is related to information security, in particular, the compliance contracts between consumers and service provider. Service Level Agreements (SLAs) are contracts in which requirements about service operation and delivery as well as penalties in case of non-compliance of these requirements are defined. A SLA is usually defined in terms of availability and performance requirements, and data security requirements are normally not specified in details as these requirements. The need for security requirements specified in an SLA, especially confidentiality and integrity to the cloud computing paradigm, as well computing architectures to deal with SLA security requirements and management of cloud services based on SLA security requirements in an automated manner during its entire lifecycle are still in evolution, compared to availability requirements. In order to deal with these ineeds, this work aims to propose and evaluate a framework to orchestrate the management of cloud services for the infrastructure as a service (IaaS) based on SLA security requirements, specifically the confidentiality and integrity requirements. The management proposed by the framework comprehend the steps of the SLA lifecycle: i) SLA specification and definition; ii) SLA deployment and management; iii) SLA execute and monitoring; and iv) SLA termination. The validation of proposed framework is performed by its application in a usage scenario, checking the compliance with defined security requirements and specified in the SLA. To ensure the security of proposed framework and its cloud computing environment integration, a threat modeling is performed and mitigation actions are presented. At last, it is shown that the proposed management framework meets the specified framework requirements.

Full textIn pig, very little information is available on the three non classical MHC class I genes SLA-6, -7 and -8 (SLA-Ib genes). Our aim was to increase knowledge on SLA-Ib genes by studying their polymorphism, transcription and protein expression. Full length transcripts were characterized from thymus and brain of MeLiM pigs resulting in the annotation of 8 exons for SLA-7 and -8 and 7 exons for SLA-6. The three full length cDNAs encode molecules with a predicted folding consistent with peptide presentation. No additional transcript was found for SLA-8 while four and five were detected for SLA-6 and SLA-7, respectively, suggesting that some soluble forms of these molecules may exist. For SLA-7, an alternative spliced variant was found in the 3’UTR of the gene after the termination codon suggesting possible post-transcriptional regulation of the gene. Polymorphism studies confirmed a limited nucleotide polymorphism but revealed an unexpected copy number variation for SLA-7. Ongoing experiments are still in progress to characterize monoclonal antibodies specific of each SLA-Ib molecule in transient transfection systems. Our overall results provided significant new data on SLA-Ib genes and will pave a way toward more functional analyses related to their putative function in immuno-tolerance

Full textWeb services choreographies are a more scalable and flexible way to compose services than a centralized approach like orchestrations, and its role in the integration and communication of large-scale systems is vital for the goals of SoC (Service Oriented Computing) and Future Internet. Currently,Web services choreographies have several research challenges. From all challenges, quality of service (QoS) and monitoring of Web services choreography are important research lines. The goal of this work is to propose and implement a mechanism for non-intrusive monitoring of Web services choreography based on SLAs (Service Level Agreements) that define constraints of QoS attributes in a probabilistic way. This thesis proposes a mechanism for Web services choreographies that:(1) defines QoS requirements; (2) specifies probabilistic contracts on QoS parameters using SLAs; and (3) monitors, non-intrusively, the enactment of Web services choreographies to detect SLA violations.

In this context, It is about evaluate queries named hybrid because they entails aspects related with classic queries, mobile and continuous provided by static or nomad data services in mode push or pull. The objective of my thesis is to propose an approach to optimize hybrid queries based in multi-criteria preferences (i.e. SLA – Service Level Agreement). The principle is to combine data services to construct a query evaluator adapted to the preferences expressed in the SLA whereas the state of services and network is considered as QoS measures

Full textContinuous monitoring of software is necessary to determine whether the software performs within required service perfomance levels. Based on collected data, it is possible to predict the future performance of applications and to plan further actions in order to maintain the required service levels. The theme of this dissertation is the development of systems for continuous performance monitoring software, as well as the development of models for predicting the performance of software. To implement the system was used JEE technologies, but the system was developed so that it can be used for tracking software developed for other platforms. The system is modeled as a minimum impact on system performance software that is monitored. Linear regression was used for modeling the dependence of the performance environment in which the software is running. The system was used to monitor selected JEE applications.

Full textThe neurodegenerative diseases Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD) form a clinical, genetic and histopathological continuum. Mutations in CHMP2B can cause ALS or DFT. The aim of this study was to characterize a new transgenic mouse model based on the neuronal expression of the human mutation CHMP2Bintron5.The mice develop a progressive muscle weakness and motor coordination defects, associated with a distal alteration of the motoneurons. Moreover, their feeding behavior is altered and they develop social disinterest and stereotypies, while mnesic functions are spared. We observed protein aggregates in neurons and an astrocytosis, mirroring the histopathological profile of patients.The neuronal expression of the mutant CHMP2Bintron5 triggers a motor phenotype associated with dementia symptoms and histopathological hallmarks of ALS and FTD. This transgenic line willallow the study of the common mechanisms implicated in the ALS-FTD syndrom

Com o aumento de investimentos no setor da computação em nuvem e a disputa forte por consumidores que utilizem serviços em nuvens, ofertas de serviços surgem cada vez mais acirradas para conquistar o público consumidor deste mercado. E para continuar na disputa desse mercado, alguns provedores de nuvens se unem para formar federações. Esse processo envolve contratos, que visam garantir que esses provedores de serviços cumpram o que estão ofertando. Esses contratos denominados de Acordo de Nível de Serviço (em inglês, Service Level Agreement - SLA), são contratos que identificam as partes envolvidas em um negócio, além de especificar o mínimo de expectativas e limites que existe entre as partes, buscando melhorar a qualidade de serviço e a relação entre cliente e provedor. Assim, para melhor atender usuários de plataformas de nuvens federadas, este trabalho propõe a implementação de um controlador de SLA capaz de gerenciar os acordos de nível de serviço entre as nuvens federadas e os usuários de uma plataforma. Esse controlador deve trabalhar de forma dinâmica, automática, transparente e simples. Para comprovar a eficiência do controlador proposto foi utilizado como estudo de caso a plataforma BioNimbuZ para a implementação deste trabalho.
With increasing investments in the cloud computing industry and the evergrowing batle for market share, cloud service offferings are becoming ever more fierce. In order to continue to dispute this market, some cloud providers have come together to form federations. This process involves contracts, which to ensure that these service providers comply with what they are offering. The contracts signed between the parties involved, the Service Level Agreement (SLA), is an IT service contract that specifies the minimum expectations and obligations that exist between the provider and the customer, aiming to improve the quality of service and the relationship between client and provider. Thus, to better meet the needs of users of federated cloud platforms, this work proposes the implementation of an SLA controller capable of managing service level agreements between federated clouds and users of a platform. This controller should work dynamically, automatically, transparently and simply. In order to prove the efficiency of the propose SLA controller the platform BioNimbuZ was used as a case study for the implementation of this work.

Full textBackground: La SLA è una malattia rara, neurodegenerativa che colpisce i motoneuroni del midollo spinale, del tronco e della corteccia motoria. La perdita dei motoneuroni porta ad atrofia muscolare, debolezza muscolare, fascicolazioni e spasticità. Circa due terzi dei pazienti con SLA presentano una forma spinale della malattia che comincia sia dagli arti superiori che inferiori e sintomi associati a stanchezza con atrofia muscolare. Un terzo dei pazienti presentano un esordio bulbare della malattia che si manifesta inizialmente con disartria e disfagia per solidi e liquidi (paralisi bulbare progressiva). Nella maggior parte dei casi la forma spinale porta a decesso dopo 3-5 anni mentre la paralisi bulbare dopo una media di 2-3 anni. L'incidenza della SLA è riportata maggiore negli uomini che nelle donne. Il sesso influenza alcune caratteristiche fenotipiche della malattia tra cui l'età e il sito d'esordio e alcune caratteristiche cliniche. Gli effetti dell'esercizio fisico e della riabilitazione in pazienti affetti da SLA sono ancora dibattuti: se un paziente è inattivo, la perdita di allenamento e il disuso portano all’atrofia muscolare, che si va a sommare alla debolezza e all'atrofia muscolare causata dalla denervazione e dalla degenerazione dei motoneuroni. I microRNA (miRNA) sono piccole molecole di RNA (19-24 nucleotidi) a singolo filamento, non codificanti, altamente conservati nel corso dell'evoluzione che regolano finemente l'espressione genica a livello post-trascrizionale. L’up-regolazione di uno specifico microRNA determina un decremento dell’espressione del prodotto proteico corrispondente. Scopo: L'obiettivo di questo lavoro è l’identificazione di nuovi biomarcatori molecolari e biochimici che facilitino lo studio dei vari sottotipi di SLA, che diano informazioni su insorgenza e gravità di malattia e che possano essere utilizzati come indicatori di risposta in trials clinico-riabilitativi. Abbiamo studiato i livelli di espressione dei miRNA muscolo-specifici e infiammatori/angiogenici e altre molecole proteiche (Miostatina/Follistatina). L’analisi dei miRNA è stata comparata con la morfometria delle fibre muscolari. Nel siero, in particolare, abbiamo indagato le differenze tra pazienti ad esordio spinale e pazienti ad esordio bulbare mentre, nel muscolo, abbiamo analizzato le differenze tra maschi e femmine e tra pazienti con diversa età d'esordio. Metodi: In 14 pazienti SLA (10 spinali e 4 bulbari) abbiamo misurato i livelli sierici dei miRNA muscolo-specifici miR-1, miR-206, miR-133a/b, miR-27a e dei miRNA infiammatori miR-155, miR-146a, miR-221 e miR-149* e l'espressione della Miostatina e della Follistatina, due fattori regolatori antagonisti della crescita muscolare. L'analisi morfometrica delle fibre è stata correlata all'atrofia muscolare misurata con parametri biochimici molecolari. In 16 biopsie muscolari di pazienti SLA (9 maschi e 7 femmine) sono stati analizzati i livelli dei myomiRNA e dei miRNA infiammatori. I livelli circolanti dei myomiRNA sono stati analizzati anche in 12 pazienti SLA (8 maschi e 4 femmine) dopo trattamento riabilitativo di 8 settimane. Risultati: Nei pazienti SLA c'è un incremento significativo (p<0.005) dei livelli sierici del miR-206, miR-133 mentre il miR-27a è significativamente (p<0.005) ridotto confrontato con i controlli e anche tra pazienti spinali e bulbari. Il rapporto Miostatina/Follistatina risulta più alto nei pazienti SLA rispetto ai controlli, simili dati si riscontrano in pazienti SLA ad esordio bulbare rispetto a pazienti con esordio spinale. I pazienti con SLA bulbare presentano un grado più alto di atrofia muscolare rispetto ai pazienti con SLA spinale documentato dall'analisi morfometrica delle fibre. Nelle biopsie muscolari di pazienti SLA tutti i miRNA presi in esame risultano fortemente up-regolati (p<0.0001) nei pazienti rispetto ai controlli ad eccezione del miR-149*. Vi è una up-regolazione significativa (p<0.0001) di tutti i miRNA nei maschi rispetto alle femmine e nei pazienti con una età d'esordio sotto i 55 anni rispetto al gruppo di pazienti più vecchi. Dopo 8 settimane di riabilitazione tutti i myomiRNA risultano down-regolati. Conclusioni: I microRNA e altre molecole proteiche (Miostatina/Follistatina) risultano particolarmente down-regolati nei pazienti con SLA bulbare, suggerendo così il risultato di un processo atrofico muscolare più rapido e diffuso. Le differenze osservate nei sottogruppi di pazienti SLA, nel siero e nelle biopsie muscolari, potrebbero suggerire un possibile ruolo differenziale dei miRNA negli eventi patogenetici della malattia dei motoneuroni. Inoltre i nostri dati suggeriscono che i myomiRNA rappresentano possibili indicatori di recupero muscolare in risposta alla riabilitazione.
