Online Testing of Federated and Heterogeneous Distributed Systems

DiCE is a system for online testing of federated and heterogeneous distributed systems. We have built a prototype of DiCE and integrated it with a BGP router. DiCE quickly detects three important classes of faults, resulting from configuration mistakes, policy conflicts and programming errors

The Serbian version of the Juvenile Arthritis Multidimensional Assessment Report (JAMAR)

The Juvenile Arthritis Multidimensional Assessment Report (JAMAR) is a new parent/patient-reported outcome measure that enables a thorough assessment of the disease status in children with juvenile idiopathic arthritis (JIA). We report the results of the cross-cultural adaptation and validation of the parent and patient versions of the JAMAR in the Serbian language. The reading comprehension of the questionnaire was tested in 10 JIA parents and patients. Each participating centre was asked to collect demographic, clinical data and the JAMAR in 100 consecutive JIA patients or all consecutive patients seen in a 6-month period and to administer the JAMAR to 100 healthy children and their parents. The statistical validation phase explored descriptive statistics and the psychometric issues of the JAMAR: the three Likert assumptions, floor/ceiling effects, internal consistency, Cronbach\u2019s alpha, interscale correlations, test\u2013retest reliability, and construct validity (convergent and discriminant validity). A total of 248 JIA patients (5.2% systemic, 44.3% oligoarticular, 23.8% RF-negative polyarthritis, 26.7% other categories) and 100 healthy children were enrolled in three centres. The JAMAR components discriminated healthy subjects from JIA patients. All JAMAR components revealed good psychometric performances. In conclusion, the Serbian version of the JAMAR is a valid tool for the assessment of children with JIA and is suitable for use both in routine clinical practice and clinical research

DeepDive : Transparently Identifying and Managing Performance Interference in Virtualized Environments

We describe the design and implementation of Deep-Dive, a system for transparently identifying and managing performance interference between virtual machines (VMs) co-located on the same physical machine in Infrastructure-as-a-Service cloud environments. DeepDive successfully addresses several important challenges, including the lack of performance information from applications, and the large overhead of detailed interference analysis. We first show that it is possible to use easily-obtainable, low-level metrics to clearly discern when interference is occurring and what resource is causing it. Next, using realistic workloads, we show that DeepDive quickly learns about interference across co-located VMs. Finally, we show DeepDive’s ability to deal efficiently with interference when it is detected, by using a low-overhead approach to identifying a VM placement that alleviates interference.QC 20140703</p

Optimal Combination of Factors Efficient and Effective Marketing Company Mineral Water

Marketing philosophy is certainly not sufficiently present in the companies producing mineral water. Marketing, often has too little significance, there are problems of co-operation with other marketing functions. A large number of companies producing mineral water still doesn’t have a particularly organized marketing department (service or a sector). In a number of companies, despite an organized special unit for marketing, a new (marketing) business philosophy is still not accepted (in the sense that the whole organization is the acceptance of marketing philosophy). The marketing appliance in most companies - producing mineral water, is still limited mainly to the activities of marketing communications, where the research of the marketing, consumers, products, pricing, depending on the estimated demand of channel sales and other strategic marketing activities are much weaker

Har bolagiseringen av idrottsföreningar gett önskad effekt? : En fallstudie om idrottsaktiebolag ger bättre finansiella nyckeltal samt bättre sportsligt resultat

Bakgrund och problem: År 1999 blev det tillåtet för idrottsföreningar med elitverksamhet att bilda aktiebolag. I dag har endast 23 stycken idrottsföreningar av ungefär 20 000 valt att bilda aktiebolag som man upplåtit sin serieplats till. Inför Riksidrottsmötet 1997 lämnade AIK, Svenska ishockeyförbundet samt några enstaka mindre föreningar in en motion om att idrottsföreningar skulle få möjlighet att driva föreningen i en alternativ assoicationsform. Argumentet för denna motion var att detta skulle ge en möjlighet för svensk idrott att kunna konkurrera sig med internationella föreningar. En bättre ekonomi skulle ge bättre sportsliga resultat. För att kunna närma sig den internationella nivån behövs stora finansiärer, vilket man inte hade möjlighet till genom den associationsform föreningar var tvungna att bedrivas som. Problemformulering: Ger bolagiseringen bättre ekonomiska och sportsliga resultat? Syfte: Syftet med denna studie är att undersöka hur föreningens finansiella resultat och sportsliga resultat påverkas av den nya bolagiseringen. Metod: Studien har genomförts som en kvantitativ fallstudie på fyra stycken fotbollsföreningar som bildat aktiebolag. Ekonomiska värden och tabellposition har sedan analyserat för idrottsAB från 1999 till 2011 samt över alla lagen i allsvenskan 2011 och superettan 2011. Studien innehåller även kvalitativa inslag. Slutsats: Slutsatsen är att bolagiseringen av elitverksamheten för föreningar varken ger ekonomiska eller sportsliga lyft.Background and problem: In 1999 it became allowed for sport clubs to run their clubs as a company. In Sweden today, there is only 23 of approximately 20000 sport clubs that runs their club as a company. in 1997, before the swedish national sport meeting, a few clubs, such as AIK, and the Swedish Icehockey Association submitted a motion that included a request that the clubs could be runned in an another legal form. The main reason for this motion was that it would give the clubs other opportunities for financing, and that would make the clubs competitive in Sweden such as international. To approach the international clubs, the clubs in Sweden needed major external financiers, which was not allowed before.A better economy at the clubs whold lead to better results on the pitch. Problem formulation: Does the corporatisation of the Swedish football clubs give better economic-and sport results? Purpose: The purpose of this study is to find out how the economic and sport results depend on the corporatisation. Method: This case studie has been performed with a quantitative method on four football companies in the two major leagues. Economical values and the positions in the leagues between 1999-2011. There is also a comparision between the companies and the other clubs in the league for 2011. The studie also includes qualitative elements. Conclusion: The conclusion is that the corporatisation of the Swedish football clubs does not affect the economic results and sport results

Accelerating resource allocation in virtualized environments using workload classes and/or workload signatures

Systems, methods, and apparatus for managing resources assigned to an application or service. A resource manager maintains a set of workload classes and classifies workloads using workload signatures. In specific embodiments, the resource manager minimizes or reduces resource management costs by identifying a relatively small set of workload classes during a learning phase, determining preferred resource allocations for each workload class, and then during a monitoring phase, classifying workloads and allocating resources based on the preferred resource allocation for the classified workload. In some embodiments, interference is accounted for by estimating and using an "interference index"
