Повний текст джерелаThe development and analysis cloud is a rapid development system being designed to support the Air Force Research Lab (AFRL) Simulation & Technology Assessment Branch. The purpose is to isolate research, development, test, and evaluation of unique software within a Zone D enclave [1] to allow researchers and analysts to develop and test software free of the many IT requirements that hamper development and without risk of contaminating the overall Air Force network. The cloud system is being designed so researchers and analysts will utilize Software as a Service (SaaS) models. Such a model makes it transparent to users such things as where the software originates and any licensing concerns. Utilities, tools, and other enhancing software that users need are published and using them frees the developer to focus on their specific development efforts versus tertiary development modules.

Повний текст джерелаPreterm infants’ cribs in Neonatal Intensive Care Unit (NICU) of “Women’s and Children’s Hospital G. Salesi” of Ancona are surrounded by many devices for the monitoring, diagnosis and treatment of diseases, which provide a huge amount of data that, until now, was only displayed on monitors and periodically transcribed in a paper medical record. Then manual notes were regularly, but not immediately, transcribed in an electronic sheet on a NICU PC with the risk of errors and forgetfulnesses. In this context, physicians have expressed the need to automatically gather data from all these devices to ensure that no key details for patient care were overlooked, as they are aware that the automation of this process could improve the implementation of the procedures of their daily clinical practice. The objective of this thesis is to allow the interfacing of NICU biomedical instruments into a single cloud-based infrastructure that enables the communication between different medical devices and a unique DB. The proposed architecture permits the automation of the process of device data collection, transmission, storage, processing and availability for medical staff, that is guaranteed through the implementation of a web interface that exceeds the functionalities of a simple Electronic Medical Record, thanks to the development of innovative clinical tools. They contain data extraction and analysis techniques and decision-making algorithms, which provide in output advices, reminders, alarms, and indicators that can support physicians in predicting and diagnosing diseases, such as neonatal jaundice or motor disabilities, in monitoring physiological parameters, such as respiratory rate and growth parameters, and in making decisions about clinical problems, such as daily nutritional intakes and follow-ups. All the solutions described above have been validated through experiments conducted in the NICU under the supervision of the physicians and the Head Physician.

Повний текст джерелаTo take advantage of cloud computing benefits that boost an enterprise’s efficiency, innovation, and cost savings, the Department of Defense’s (DOD) cloud computing strategy needs to evaluate databases as a service. If the DOD is going to prioritize outsourced database server hosting, each application’s performance and agility of each must be assessed to determine if they can thrive in this new environment. We performed an experiment to compare the performance between a current Naval Postgraduate School standalone database server and a cloud version developed specifically for the experiment. The cloud environment was created both with resources less equal to and greater than the live standalone server. We simulated cloud environment traffic based on the type of queries observed in production and collected data to compare its performance against the standalone database. The results show that the cloud database performed similarly to or better than our standalone server, with equivalent resources. It achieved this level of performance without utilizing additional resources. We increased the resources dedicated to our cloud environment to test scalability, and we witnessed that the time needed to execute queries decreased significantly. We therefore concluded that our database would perform and scale favorably in a cloud environment.

Повний текст джерелаCloud computing har de senaste åren blivit alltmer populärt och möjliggör att skala beräkningskapacitet och resurser på begäran. Cloud native-applikationer är specifikt skapade för att köras på distribuerad infrastruktur. För närvarande finns det luckor i forskningen gällande design och implementering av cloud native applikationer, särskilt angående hur designbeslut påverkar mätbara värden som exekveringstid och skalbarhet. Problemet som undersöks i denna uppsats är huruvida exekveringstiden och måttet av kvalitetsskalbarhet, ηt påverkas när funktionaliteten av flera användningsfall intregreras i samma cloud native applikation. I det här arbetet skapades en cloud native applikation som kombinerar flera användningsfall för att analysera transaktionsbaserad börshandelsdata. Funktionaliteten av 3 användningsfall implementeras i applikationen: (1) generera rapporter över handelspriser, (2) detektering av avvikelser och (3) analys av relations-grafer. Applikationens exekveringstid och skalbarhet utvärderas och jämförs med kommersiella cloudtjänster, vilka fungerar som en baslinje för utvärderingen. Resultaten från användningsfall 1 och 2 jämförs med Amazon Athena, medan användningsfall 3 jämförs med Amazon Neptune. Resultaten antyder att systemets exekveringstid och skalbarhet kan förbättras genom att funktionalitet för flera användningsfall implementeras i samma system. Effekten varierar beroende på användningsfall och hårdvarukonfiguration. När samtliga användningsfall körs i en sekvens, minskar den genomsnittliga körtiden för den implementerade applikationen med upp till 17,2% medan kvalitetsskalbarheten ηt förbättrades med 10,3%för användningsfall 2. Den implementerade applikationen har betydligt kortare exekveringstid än Amazon Neptune men överträffar inte Amazon Athena för respektive användningsfall. Systemens skalbarhet varierade beroende på användningsfall. Även om det inte överträffar baslinjen i alla användningsfall, visar resultaten att exekveringstiden för en cloud native applikation kan förbättras genom att kombinera funktionaliteten hos flera användningsfall inom ett system. De potentiella prestandavinsterna varierar dock beroende på användningsfallet och kan vara mindre än vinsterna av att välja en annan lösning.

A slew of articles have been written about the fact that computing will eventually go in the direction of electricity. Just as most software users these days also own the hardware that runs the software, electricity users in the days of yore used to generate their own power. However, over time with standardization in voltage and frequency of generated power and better distribution mechanisms the generation of electricity was consolidated amongst fewer utility providers. The same is being forecast for computing infrastructure. Its is being touted that more and more users will rent computing infrastructure from a utility or "cloud" provider instead of maintaining their own hardware. This phenomenon or technology is being referred to Cloud Computing or Utility Computing. Cloud computing has been in existence in some form or the other since the beginning of computing. However, the advent of vastly improved software, hardware and communication technologies has given special meaning to the term cloud computing and opened up a world of possibilities. It is possible today to start an ecommerce or related company without investing in datacenters. This has turned out to be very beneficial to startups and smaller companies that want to test the efficacy of their idea before making any investment in expensive hardware. Corporations like Amazon, SalesForce.com, Google, IBM, Sun Microsystems, and many more are offering or planning to offer these infrastructure services in one form or another.
(cont.) An ecosystem has already been created and going by the investment and enthusiasm in this space the ecosystem is bound to grow. This thesis tries to define and explain the fundamentals of cloud computing. It looks at the technical aspects of this industry and the kind of applications where cloud can be used. It also looks at the economic value created by the platform, the network externalities, its effect on traditional software companies and their reaction to this technology. The thesis also tries to apply the principle of multi-homing, coring and tipping to the cloud-computing platform and explain the results. The hurdles for both users and providers of this service are also examined in this thesis.

Повний текст джерелаThe aim of this work is to provide a comprehensive analysis of cloud and aerosol interaction over South-East Atlantic, to quantify the overall aerosol impact on the regional radiation budget. We used data from MODIS, PARASOL and CALIPSO satellites, that fly in close proximity on the same sun-synchronous orbit and allow for complementary observations of the same portion of the atmosphere, within a few minutes. The main idea is to use CALIPSO vertical information to define whether or not aerosol and cloud layers observed by MODIS and PARASOL are mixed and interacting. We found evidences that, in case of interaction, cloud properties are strongly influenced by aerosol presence (first indirect effect). In particular, there is a decrease in cloud droplet effective radius and liquid water path with aerosol enhancement. On the other hand, we could not evidence any significant impact on the cloud reflectance. We also analyzed the aerosol impact on precipitation (second indirect effect). In polluted low clouds over the ocean, we found evidence of precipitation suppression and cloud cover increase with increasing aerosol concentration. On the other hand, cloud fraction is shown to be affected by aerosol presence, even if pollution particles are located above cloud top, without physical interaction. This observation is interpreted as a consequence of the aerosol radiative effect. Aerosol shortwave direct (DRF) and indirect (IRF) radiative forcing at TOA has been quantified, with the use of a radiative transfer model constrained by satellite observations. For the direct effect, there is a competition between cooling (negative, due to light scattering by the aerosols) and warming (positive, due to the absorption by the same particles). The six year (2005-2010) mean estimate is equal to -0. 07 (DRF) and -0. 05 (IRF) W/m². The resulting total aerosol forcing is negative (cooling) and equal to -0. 12 W/m²

Cisco's security business segment with over $2 billion in revenue in fiscal 2018, makes Cisco one of the largest enterprise security players in the market. It is also one of the fastest growing business segments for Cisco, with last five years' CAGR at 12%. While this growth rate is in line with the estimated CAGR for cybersecurity market growth between 2018 - 2022, another leading incumbent's growth rate shows there is an opportunity to grow even faster. What can Cisco do to accelerate its security business group's growth and, more broadly, how can Cisco maintain its leadership position in a rapidly evolving and highly fragmented cybersecurity market? The goal of this thesis is two folds: first, is to discover the emerging cybersecurity needs for enterprises under the dynamic threat landscape in mobile, cloud-era, and the resultant growth opportunities and challenges these present to Cisco's security business group. Second, is to discover the main elements of Cisco security business group's current growth strategies and to evaluate platform thinking as a potential growth strategy for Cisco's Cloud Security business. We find Cisco Umbrella, a recently launched cloud security offering exhibits potential to become a foundation for Cisco Cloud Security as an open platform ecosystem. We conclude by discussing a potential future platform direction for Cisco Umbrella and raise follow-on questions for further consideration.

Повний текст джерелаVirtual Machine Introspection (VMI) consists inmonitoring VMs security from the hypervisor layer which offers thanks to its location a strong visibility on their activities in addition to a strong isolation from them. However, hypervisor view of VMs is just raw bits and bytes in addition to hardware states. The semantic difference between this raw view and the one needed for VM security monitoring presents a significant challenge for VMI called “the semantic gap”. In order to obtain semantic information about VM states and activities for monitoring their security from the hypervisor layer, we present in this thesis a set of techniques based on analysis and reuse of VM kernel binary code. These techniques enable to identify addresses and names of most VM kernel functions then instrument (call, intercept and analyze) them to automatically bridge the semantic gap regardless of challenges presented by compiler optimizations and kernel base address randomization

Повний текст джерелаIndustry experts recognize the cloud and cloud-based services as advantageous from both operational and economic perspectives, yet the gap is that individuals and organizations hesitate to accept the cloud because of concerns about security and privacy. The purpose of this study is to examine what factors that may influence the cloud acceptance by IT professionals by focusing on the principal research question: To what extent do ease of use, usefulness, attitude, security apprehensions, compatibility, and trust predict IT security professionals’ acceptance of cloud computing. The population for this study consisted of IT security professionals who either had industry security certifications or had been in a security position for at least two years. Sample inclusion criteria consisted IT professionals with the qualification described above and over the age of 18 who were living in the United States. The study survey was administered using SurveyMonkey, which randomly selected and recruited potential participants who met the sample criteria from a participant database, resulting in ninety-seven total study participants. Among the six factors examined, perceived usefulness, attitudes, security apprehensions, and trust were found to significantly predict cloud acceptance. The results indicate that cloud service providers should focus their attention on these factors in order to promote cloud acceptance.

Повний текст джерелаJordens atmosfär är ett känsligt system som lätt förändras av mikro- samt makrofysikaliska variationer. Stora minskningar i föroreningsnivåer av svaveldioxid över centrala Europa från 1980 till 2000-talet ledde till minskade masskoncentrationer av fasta och flytande atmosfäriska partiklar. Detta ger en möjlighet att undersöka hur dessa partiklar påverkar atmosfären. Nyligen utvecklad klimatologisk satellitdata användes för att analysera statistik av molnegenskaper under fyra år i en högt förorenad atmosfär (1985-88) och fyra år i en mindre förorenad atmosfär (2004-07). De två perioderna undersöktes i samarbete med Enheten för atmosfärisk fjärranalys av forskningsavdelningen till Sveriges meteorologiska och hydrologiska institut (SMHI). Molntopptemperaturen för moln i vätskefas över förorenande områden under den tidigare perioden var mer än 2 K kallare och mer än 5 K kallare för endast optiskt tunna moln i vätskefas. Förändringarna i masskoncentrationer för atmosfäriska partiklar och droppar med svaveldioxidusläpp som ursprung visas vara högst möjliga att ligga bakom de observerade molnförändringarna.

Thesis, Blekinge Tekniska Högskola, Institutionen för datavetenskap, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:bth-19723.
Повний текст джерелаBakgrund: Idag pågår det en delad debatt gällande lämpligheten för svenska myndigheter att använda utländska molntjänster. Lagstiftningar som bland annat amerikanska CLOUD Act utgör ett hot för svensk suveränitet, eftersom data lagrad i svenska serverhallar kan komma att vara föremål i amerikanska domslut. Vissa organisationer menar då att uppgifter som omfattas av offentlighets- och sekretesslagen (OSL) kan sannolikt betraktas som röjda. Nyttan med att använda molntjänster är generellt sett stor - och bör därför strävas efter att användas. eSam, som är ett program för myndighetssamverkan, menar i ett uttalande att kryptering skulle kunna förhindra ett röjande och möjliggöra användande av dessa molntjänster, men ifrågasätter hur det bör gå till. Syfte: Syftet med detta arbete är att undersöka vilka krav på krypteringsmekanismer som krävs för att lagra sekretessreglerad information i molntjänster utan att bryta mot svensk lagstiftning. Molntjänstleverantörerna, Amazon Web Services (AWS), Microsoft Azure och Google Cloud, kommer att undersökas för att se om dessa lever upp till de identifierade kraven. Historiskt sett är tjänsteleverantörers tillgång till krypteringsnycklar ett stort hot. Därför ska en alternativ krypteringsmetod som bevarar krypteringsnyckel undangömd från tjänsteleverantören undersökas, men som samtidigt bevarar viss funktionalitet med molntjänsten. Metod: För att kunna skapa korrekta och rimliga krav på krypteringsmekanismer skapas hotmodeller som utgår från juridiken. En SWOT-analys kommer användas för att jämföra vilka molntjänstleverantörer som lever upp till kraven. För att undersöka möjligheten och nyttan med alternativa krypteringsmekanismer, implementeras ett förslag på system där varken krypteringsnyckel eller data i klartext tillgås molntjänstleverantören. Resultat: Resultatet visar att populära tjänster som exempelvis Office 365 och G Suite är direkt olämpliga för användning av svenska myndigheter. Det visar sig att IaaS-tjänster som tillhandahålls av AWS och Microsoft Azure i viss mån lämpar sig för användning - förutsatt att vissa krav uppfylls. Resultatet visar även att det är möjligt att använda alternativa krypteringsmetoder som en del i ett dokumenthanteringssystem. Slutsats: Svenska myndigheter bör sträva efter att öka sin digitalisering, men bör ta ordentliga försiktighetsåtgärder innan eventuella upphandlingar av molntjänster sker. Skulle det juridiska eller säkerhetspolitiska läget förändras kommer de krav på krypteringsmekanismer som presenteras i arbetet inte längre vara tillämpliga. I ett förändrat läge bör svenska myndigheter istället använda alternativa lösningar som inte påverkas, likt det dokumenthanteringssystem som arbetet presenterar.

Повний текст джерелаAn established cloud analysis routine has been modified for use in the Arctic. The separation of clouds from the snow and sea ice backgrounds is accomplished through a multispectral technique which utilizes VHRR channel 2 (visible), channel 3 (near infrared) and channel 4 (infrared) data. The primary means of cloud identification is based on a derived channel 3 reflectance image. At this wavelength, a significant contrast exists between liquid clouds and the arctic backgrounds, unlike in the standard visible and infrared images. The channel 3 reflectance is obtained by first using the channel 4 emission temperature to estimate the thermal emission component of the total channel 3 radiance. This thermal emission component is subsequently removed from the total radiance, leaving only the solar reflectance component available for analysis. Since many ice clouds do not exhibit a substantially greater reflectance is channel 3, the routine exploits differences in transmissive characteristics between channels 3 and 4 for identification. The routine was applied to six case studies which had been analyzed by three independent experts to establish 'ground truth'. Verification of the cloud analysis results, through a comparison to the subjective analyses, yielded impressive statistics. A success rate of 77.9% was obtained with an arguably small data base of 131 undisputed scenes

Повний текст джерелаFor multispectral Remote Sensing (RS) image analysis, a big problem is that original dataalways include Clouds-Interference (CI). Especially in the bad weather conditions, the CI is evidentin RS image. So during the pre-processing of RS image, the CI should be reduced as much aspossible. In this paper, reducing CI is researched as the central problem, so that much Ground-Objects Feature (GOF) can be obtained. An analysis about the clouds reflection in differentSpectral-Bands (SBs) was done based on optical theory and early researches. Moreover, therelationships between clouds reflection and ground-objects reflection are presented to understandwhat the Digital Number (DN) represented in each SB, and to reduce the impact of CI the Same DNSpectral Matching Method (SDN-SMM) based on the multispectral application is applied. Finally,two cases are tested using Matlab Programme to indicate the rationality and practicability of SDNSMM.About SDN-SMM, some advantages and disadvantages are concluded through discussion onfinal results. The method can be used in any kind of multispectral sensors image with simplecalculation, while, the original data of clouds-free region will not be changed. However, the qualityof CI reduction depends on the precision of clouds identification and the SB which is used forspectral position relationship creating. In the end of this paper, the improvement is also presentedfor the future work.

Повний текст джерелаActualmente, los servicios de telecomunicaciones se implementan comúnmente en redes privadas, controladas y mantenidas por los operadores de telecomunicaciones, por proveedores de servicios de colocación o, hasta cierto punto, por proveedores de hardware y software. Sin embargo, con el presente desarrollo de la tecnología de ’Cloud computing’, se puede considerar la posibilidad de implementar servicios de telecomunicaciones en la nube, aprovechando su alta disponibilidad, distribución geográfica y facilidad de uso. Además, este cambio puede reducir las preocupaciones de los operadores en relación al mantenimiento del hardware y de la red, delegando en los proveedores del servicio de ’Cloud computing’, los cuáles deberán proporcionar un servicio consistente, cumpliendo así con los requisitos de los servicios de telecomunicaciones. Por otra parte, la virtualización propociona la posibilidad de cambiar rápida y fácilmente la topología de la red, facilitando la adición y supresión de maquinas y servicios, y, por tanto, permitiendo a los operadores adaptarse a sus necesidades sobre la marcha. El objetivo de esta tésis es analizar y evaluar en nivel de rendimiento, desde el punto de vista de la red, que se puede conseguir usando recursos de ’Cloud computing’ para implementar un servicio de telecomunicaciones, llevando a cabo experimentos tanto en el laboratorio como en un entorno real. Estos análisis fueron realizados utilizando un prototipo de un servidor de conmutación móvil (MSC-S) de Ericsson, aunque los resultados pueden adaptarse a otras aplicaciones con unos requisitos similares. Para probar esta propuesta en un entorno real, se realizó una encuesta de proveedores de servicios de ’Cloud computing’, con el objetivo de evaluar sus servicios teniendo en cuenta nuestros requisitos de hardware y red. Finalmente, un proveedor fue escogido y su servicio evaluado basándonos en los requisitos de la aplicación MSC-S. En este documento proporcionamos los resultados de esa evaluación y los comparamos con los obtenidos en el laboratorio. Los resultados de ambas evaluaciones fueron satisfactorios e indican la posibilidad de implementar servicios de telecomunicaciones en la nube, siempre que la nube cumpla los requisitos impuestos por dichos servicios de telecomunicaciones.
Nuförtiden är telekommunikationstjänster ofta uppsatta i privata nätverk, som kontrolleras och underhålls av teleoperatörerna själva, av samlokaliserande tjänsteleverantörer eller i viss utsträckning av deras hårdvaruoch programvaru-leverantörer. Med den nuvarande utvecklingen av Cloud Computing-resurser kan man dock överväga om dessa tjänster kan och bör genomföras i ett Cloud, vilket drar fördel av Cloud Computings höga tillgänglighet, geografiska spridning, och enkla användning. Denna migration minskar även teleoperatörernas oro angående hårdvaru- och nätverks-underhåll genom att överlåta detta till Cloud Computing-leverantörerna, som kommer att behöva leverera en hög tillgänglighet och konsekvent service för att uppfylla telekommunikationstjänsternas krav. Dessutom ger virtualisering möjlighet att enkelt och snabbt ändra ett Clouds nätverkstopologi, vilket underlättar tillägg och borttagning av maskiner och tjänster, vilket hjälper teleoperatörer att snabbt anpassa sig till deras krav. Målet med examensarbetet är att analysera och uppskatta prestandan, från nätets perspektiv, som kan uppnås vid användning av Cloud Computingresurser för att genomföra en teletjänst, genom praktiska experiment både i laboratorium och i verkligheten. Dessa mätningar och analyser utfördes med en prototyp av en Ericsson mobilomkopplingscentralserverapplikation (MSCS), även om de erhållna resultaten skulle kunna anpassas till andra program med liknande krav. För att potentiellt kunna testa denna metod i en verklig miljö användes en tidigare leverantörs undersökning för att utvärdera deras tjänster baserat på våra krav på hårdvara och nätverksegenskaper, och genom detta välja en lämplig kandidatmiljö för våra syften. En Cloud-leverantör valdes och dess tjänster utvärderades vidare baserat på MSC-Ss applikationskrav. Vi redovisar resultatet av vår testprocess i den här miljön och jämför det med resultaten av tester i laboratoriemiljö. Resultaten från båda uppsättningarna av tester var väl korrelerade och visar på potentialen av att implementera telekommunikationstjänster i en Cloud-miljö, om detta Cloud uppfyller de kraven som ställs av telekommunikationtjänsterna.
