Full textAbstract:
Kubernetes has become the leading orchestration platform for containerized Software-as-a-Service (SaaS) applications, offering scalability, resilience, and automation. However, maintaining high availability (HA) and optimizing performance in multi-tenant SaaS environments remains challenging due to workload fluctuations, resource contention, and network overhead. This paper proposes a systematic approach to optimizing Kubernetes-based SaaS applications by integrating advanced workload distribution, AI/ML-driven predictive scaling, and efficient resource management strategies. We evaluate the effectiveness of horizontal and vertical scaling mechanisms, node affinity constraints, and service mesh policies in mitigating performance bottlenecks while ensuring HA. Additionally, we explore adaptive autoscalers, optimized ingress controllers, and distributed tracing frameworks for real-time observability and traffic engineering. Experimental evaluations benchmark scheduling and scaling strategies under varying workload scenarios in real-world SaaS environments. This paper presents practical insights into designing resilient, high-performing Kubernetes architectures that enhance fault tolerance and cost efficiency in enterprise SaaS deployments.

The rapid growth of Software-as-a-Service (SaaS) applications in cloud environments has introduced new challenges for digital forensics investigators. Traditional forensic methods are often insufficient to collect, preserve, and analyze digital evidence from cloud-based environments. To address these challenges, this scope will propose the development of an Intelligent System for Cloud SaaS Forensic (ISC-SF) for OpenStack environment. The ISC-SF will integrate machine learning algorithms with the SaaS model and will present the algorithms to design for attribute selection, machine learning model training, attack detection, evidence extraction, collection, and analysis. This paper provides an overview of OpenStack architecture, OpenStack services, and log locations. The ISC-SF aims to revolutionize the field of cloud SaaS forensic investigation by leveraging intelligent algorithms in a controlled cloud environment.

Full textAbstract:
This research presents an optimization technique for route planning using simulated ant agents for dynamic online route planning and optimization of the route. It addresses the issues involved during route planning in dynamic and unknown environments cluttered with obstacles and objects. A simulated ant agent system (SAAS) is proposed using modified ant colony optimization algorithm for dealing with online route planning. It is compared with evolutionary technique on randomly generated environments, obstacle ratio, grid sizes, and complex environments. The evolutionary technique performs well in simple and less cluttered environments while its performance degrades with large and complex environments. The SAAS generates and optimizes routes in complex and large environments with constraints. The traditional route optimization techniques focus on good solutions only and do not exploit the solution space completely. The SAAS is shown to be an efficient technique for providing safe, short, and feasible routes under dynamic constraints and its efficiency has been tested in a mine field simulation with different environment configurations and is capable of tracking the moving goal and performs equally well as compared to moving target search algorithm.

Purpose Cloud computing is qualified to present proper limitless storage and computation resources to users as services throughout the internet. Software as a service (SaaS) layer is the key paradigm perspective in the software layer of the cloud computing. SaaS is connected by business applications to access consumers on existing public, private and hybrid cloud models. This purpose of this paper is to present a discussion and analysis on the SaaS layer based on business applications in the cloud environment in form of a classical taxonomy to recognize the existing techniques, challenges and efforts. Design/methodology/approach Existing techniques, challenges and efforts are classified into four categories: platform-dependent, application-dependent, data-dependent and security-dependent mechanisms. The SaaS layer mechanisms are compared with each other according to the important factors such as the structural properties, quality of service metrics, applied algorithms and measurement tools. Findings The benefits and weaknesses of each research study are analyzed. In the comparison results, the authors observed that the application-based method, the non-heuristic algorithms, the business process method have the highest percentage of the usage in this literature. Originality/value The SaaS layer mechanisms based on business applications have some main features such as high accessibility, compatibility, reusability and collaboration to provide activated application and operation services for user with help of Web browsers. A comprehensive analysis was presented as originality on the SaaS layer mechanisms based on business applications for high level of the cloud environment that 46 peer-reviewed studies were considered.

Full textAbstract:
Cloud computing is an emerging paradigm which provides a flexible and diversified trading market for Infrastructure-as-a-Service (IaaS) providers, Software-as-a-Service (SaaS) providers, and cloud-based application customers. Taking the perspective of SaaS providers, they offer various SaaS services using rental cloud resources supplied by IaaS providers to their end users. In order to maximize their utility, the best behavioural strategy is to reduce renting expenses as much as possible while providing sufficient processing capacity to meet customer demands. In reality, public IaaS providers such as Amazon offer different types of virtual machine (VM) instances with different pricing models. Moreover, service requests from customers always change as time goes by. In such heterogeneous and changing environments, how to realize application auto-scaling becomes increasingly significant for SaaS providers. In this paper, we first formulate this problem and then propose a Q-learning based self-adaptive renting plan generation approach to help SaaS providers make efficient IaaS facilities adjustment decisions dynamically. Through a series of experiments and simulation, we evaluate the auto-scaling approach under different market conditions and compare it with two other resource allocation strategies. Experimental results show that our approach could automatically generate optimal renting policies for the SaaS provider in the long run.

Purpose Fierce competition drives software vendors to rely on Software-as-a-Service (SaaS) strategies and to continuously match new releases with customers’ needs and competitors’ moves. Such recurrent release practices pose specific challenges for software vendors which shape how they service customers. To address these challenges, this paper aims to apply service science to innovate strategies for SaaS release management. Design/methodology/approach Based on action research methodology, the authors collaborated closely with Software Inc., an alias for a large multinational software provider, to apply service-dominant logic systematically, to analyze and improve its SaaS release management process and to support ongoing value co-creation with its customers. Findings The authors provide a detailed account of how Software Inc. improved its SaaS release management practices; they extend current understanding of service innovation dynamics in SaaS environments and offer a model of value co-creation in SaaS release management grounded in the findings from Software Inc. Research limitations/implications The research draws on a single case study with particular characteristics. Still, it allows for analytical generalizations with both theoretical and practical implications for how SaaS managers can improve recurrent release practices based on foundational service-dominant logic principles. Practical implications The authors suggest that SaaS managers concentrate on knowledge-sharing with customers, ensure continuous communication among teams supporting the service, re-organize release management to enhance the value co-creation process, use technology to improve customer service experiences and use service mapping to improve release management and service quality. Originality/value The authors bridge service-dominant logic principles and SaaS knowledge by demonstrating how service-dominant logic can be used to improve SaaS release practices and by offering conceptual and practical knowledge about value co-creation between customers and suppliers in SaaS contexts.

Full textAbstract:
Graph-based search algorithms offer significant advantages in optimizing query performance, scalability, and search relevance in large-scale, multi-tenant Software-as-a-Service (SaaS) applications. Traditional search methodologies often struggle with high query volumes, dynamic indexing, and tenant isolation, leading to increased latency and inefficient resource utilization. This paper explores the role of graph traversal techniques, including Dijkstra’s Algorithm, A* Search, Breadth-First Search (BFS), and PageRank-inspired methods, in enhancing search efficiency. Various indexing strategies, data partitioning models, and caching mechanisms are analyzed to optimize search response times while ensuring scalability. Additionally, the study examines distributed graph processing frameworks and parallelization techniques to improve performance in cloud-native SaaS architectures. Experimental results demonstrate how graph-based search optimizations reduce query latency, enhance recommendation accuracy, and improve overall search system efficiency in large-scale SaaS platforms. The findings provide practical insights for designing robust, high-performance search architectures tailored for modern enterprise SaaS environments.

Full textAbstract:
As a software delivery model, Software as a Service (SaaS) has attracted considerable attention from software providers and users. Most traditional companies are shifting their businesses to an SaaS model. SaaS development is a very complicated process and its success depends on architectural design and development. A Manufacturing Execution System (MES) was used at the expense of licensing fees for features not used in the On-Premise environment, although the features used vary depending on the manufacturing environment. In an SaaS environment, MES is applied with a function-specific container approach through a Microservice Architecture (MSA) to select and employ only the necessary functions. Furthermore, as the number of customers of virtualized applications increases in SaaS-based services, complexity and operating costs increase; thus, Multi-tenancy Architecture (MTA) technology, which serves all customers through a single instance of the application is crucial. Thus, in this study, we investigate the MTA approach and propose a suitable MTA for the manufacturing execution system. Real-time response is crucial to achieving a cyber-physical system of digital manufacturing in SaaS-based MES. Furthermore, SaaS-based big data analytics and decision-making cannot meet the needs of numerous applications in real-time sensitive workplaces. In this study, we propose an SaaS-based MSA/MTA model for real-time control of Internet of Things (IoT) Edge in digital manufacturing (SaaMES), an architecture of SaaS-based MES with MSA and MTA to meet vulnerable workplaces and real-time responses in Cloud environments. The analysis is used by applying the Autoencoder and Generic Adversarial Networks analysis model to IoT Edge for the connection between the Cloud environment and work site to enable real-time response and decision-making through communication using OPC-UA and small-scale analysis.

Cloud Computing (CC) is one of the fast growing computer network technologies and many companies offer their services through cloud network. Cloud Computing has many properties with respect to the existing traditional service provisions like scalability, availability, fault tolerance, capability and so on which are supported by many IT companies like Google, Amazon, Salesforce.com. These IT companies have more chances to adapt their services into a new environment, known as Cloud computing systems. There are many cloud computing services which are being provided by many IT companies.The purpose of this thesis is to investigate which cloud environment (public, private and hybrid) and services (Infrastructure as a Service, Software as a Service, and Platform as a Service) are suitable for Swedish Armed Forces (SWAF) with respect to performance, security, cost, flexibility and functionality. SWAF is using private (internal) cloud for communications where both sensitive and non-sensitive information are located in the internal cloud. There are problems like maintenance of hardware, cost issues and secure communication while maintaining the private cloud. In order to overcome those problems we have suggested a hybrid and community cloud environment and SaaS, IaaS, PaaS services for SWAF.For suggesting these cloud environments and cloud services we have performed a literature study and two empirical studies (survey and interviews) with different organizations.A new cloud model is designed based on the suggested cloud environment, separate storage spaces for sensitive and non-sensitive information, suitable services and an effective infrastructure for sharing the internal information for SWAF.

Full textAbstract:
Nanomaterials are defined as structures possessing one or more dimensions below 100 nanometres in size. They display unique properties that arise as a result of quantum behaviours, owing to their high surface area to volume ratios. Self-assembling nanomaterials (SANs), where individual components referred to as “building blocks” spontaneously organise into complex structural arrangements, is a prominent field that offers technological innovation within medicine and beyond. To effectively exploit this approach in healthcare however, a high-level of behavioural understanding within biological systems is required, which has yet to be ascertained. Accordingly, work undertaken in this thesis aimed to investigate how gold nanoparticles self-assemble and interact within a biological environment. Molecular recognition and electrostatic attraction, two different underpinning mechanisms of self-assembly were studied. Based on findings within this thesis, the latter approach was chosen for further development. Corresponding functional gold nanoparticles were incorporated into PEGylated liposomes using a novel method and extensively characterised. Comparative cytotoxicity evaluation was carried out in vitro on a male Chinese hamster lung fibroblast cell line (V79), employing MTT and LDH assays. Investigations focused on identifying any differences in biological response after treatment with individually dispersed gold nanoparticles and as they underwent in situ self-assembly. Cellular uptake and any ensuing self-assembly was investigated using a combination of electron microscopy and elemental analysis on thin-sectioned specimens. Results presented in this thesis reveal that both electrostatic interactions and molecular recognition facilitate self-assembly under aqueous conditions. Within a biologically relevant medium however, considerable nanoparticlebiomolecule complex formation occurs and only particles exploiting electrostatic interactions persist to self-assemble. Gold nanoparticles were capable of being encapsulated within liposomes by exploiting electrostatic attractions between oppositely charged lipids and ligands on particle surfaces. The novel method resulted in variable internalised gold to lipid ratios, hypothesised to result from differing magnitudes of electrostatic attraction during preparation. At clinically relevant concentrations, gold nanoparticles functionalised with cationic or anionic ligands did not display significant cytotoxicity. A significant difference in cytotoxicity was displayed as they underwent in situ assembly however. Cellular internalisation of gold was evidenced, with nanoparticles seen to accumulate and reside within cellular vacuoles, but no confirmation of self-assembly was obtained. In conclusion, the current work provides further knowledge regarding the feasibility, risk and current limitations associated with utilising and evaluating nanomaterials for in-situ self-assembly within biological environments. Extensive interactions shown to occur between initial building blocks and biological components can hinder self-assembly activity, highlighting the importance of rational design when manufacturing SANs. Individual nanoparticles were encapsulated within surface-modified liposomes, demonstrating a possible strategy towards implementing further control over SANs. Cellular studies identified a difference in toxicity between individual building blocks and their assembled suprastructures, demonstrating that unique biological responses could arise from the self-assembly of SANs. Evaluation of intracellular self-assembly and the ability to differentiate between individual building blocks, assembled suprastructures and cellular components is inherently difficult. Current techniques and approaches require further development to enable routine and reliable assessment of analogous in situ self-assembling nanosystems.

Full textAbstract:
Cette thèse se concentre sur la localisation à faible puissance dans des environnements contraints, sans nécessiter d'infrastructure de localisation. Nous considérons deux cas d'utilisation cibles: la localisation de bateaux dans un port de plaisance, et la localisation de robots mobiles dans un environnement intérieur. Nous commençons par évaluer deux systèmes de localisation en temps réel ("Real Time Localition System" en anglais, RTLS) basés sur les radiofréquences (Bluetooth Angle-of-Arrival et Ultra-Wide Band ranging). Leurs principaux inconvénients sont qu'ils nécessitent le déploiement préalable de points d'ancrage, et qu'ils ne sont pas à faible consommation, ce qui les rend peu compatibles avec nos cas d'utilisation cibles. Ce travail contribue à remédier à ces inconvénients en proposant deux nouveaux systèmes: WELOC et Blip. Nous proposons également RRDV, une solution de détection de rencontre de robots pour les systèmes multi-robots. WELOC est un système de localisation basé sur les ultrasons qui réutilise les capteurs de détection de présence des bateaux déjà présents dans la marina. Il comporte un système de programmation qui déclenche l'émetteur-récepteur ultrasonique de chaque capteur de présence à des moments précis. WELOC présente le design d'un appareil mobile alimenté par batterie, capable de communiquer en toute sécurité à la fois par ultrasons et par signaux radio, et conçu à partir de composants disponibles sur le marché. Des essais en conditions réelles dans un port de plaisance dans le sud de la France montrent que l'appareil mobile peut être localisé avec une précision de l'ordre du centimètre, tout en étant à une distance de 10 m des capteurs de présence. Blip est un système d'identification des bateaux dans un port de plaisance, qui ne nécessite qu'une mise à jour logicielle des systèmes de capteurs intelligents existants dans les ports de plaisance. Il utilise les informations fournies par les capteurs de surveillance des bateaux déjà présents (installés dans la cabine d'un bateau) et les combine avec les informations provenant de l'infrastructure fixe des capteurs de présence pour identifier les bateaux sur les emplacements. Lors de nos essais en conditions réelles, le système a fait preuve d'une précision de 100 % dans l'identification des bateaux. Cette thèse propose également RRDV, un système de détection de rencontres entre robots dans un système multi-robots. De nombreux robots sont déjà équipés d'un capteur à ultrasons pour mesurer leur distance à des objets devant eux. RRDV est une mise à jour logicielle pour ces robots, leur permettant d'utiliser ces capteurs à ultrasons pour détecter les rencontres avec d'autres robots. En testant RRDV sur un système multi-robots réel, il détecte correctement 96.7% des fois où deux robots se font face pendant 5 s ou plus. La thèse contribue au domaine de recherche croissant de la localisation et des communications sans-fil à faible consommation, en proposant des solutions innovantes pour des systèmes de localisation précis et à faible consommation dans des environnements contraints. Ces solutions ont des applications non seulement dans l'industrie maritime mais aussi dans les systèmes multi-robots. La thèse démontre l'efficacité des systèmes basés sur les ultrasons et met en évidence le potentiel du matériel ubiquitaire prêt à l'emploi pour le développement de systèmes de localisation<br>This thesis focuses on low-power localization in constrained environments, without the need for localization infrastructure. We consider two target use cases: localizing boats in a marina, and localizing mobile robots in an indoor environment. We start by evaluating two RF-based Real-Time Localization Systems (RTLS), based on Bluetooth Angle-of-Arrival and Ultra-Wide Band ranging. Their main drawbacks are that they require the prior deployment of anchors and are not low power, making them poorly compatible with our target use cases. This work contributes to addressing these drawbacks by proposing two novel systems: WELOC and Blip. We further propose RRDV, a robot encounter detection solution for multi-robot systems. WELOC is an ultrasound-based localization system that re-purposes boat presence detection sensors already deployed in the marina. It features a scheduling scheme that triggers each presence sensors' ultrasonic transceiver at specific times. WELOC introduces a battery-powered mobile device capable of securely communicating with both ultrasound and radio signals, designed entirely from off-the-shelf components. Real-world tests in a real-life marina in the South of France show a mobile device can be localized with cm-level accuracy when it is up to 10 m away from presence sensors. Blip is a system for boat identification in a marina, which only requires a software update to existing smart marina sensor systems. It uses the information from already installed boat monitoring sensors (mounted in a boat's cabin), and combines that with the information from the fixed infrastructure of presence sensors to identify boats on slips. In our real-world tests, the system exhibits 100 % boat identification accuracy. This thesis further proposes RRDV, a system for detecting robot-to-robot encounters in a multi-robot system. Many robots are already equipped with an ultrasound sensor for measuring the distance to objects in front of them. RRDV is a software update to those robots, allowing them to use those ultrasound sensors for detecting encounters with other robots. When testing RRDV on a real-world multi-robot system, it correctly detects 96.7% of the times two robots face one another for 5~s or more. The thesis contributes to the growing research field of localization and low-power wireless by proposing innovative solutions for low-power and accurate localization in constrained environments. While these solutions have countless applications well beyond the ones outlined in this thesis, we chose the use cases of localization of boats in marinas and localization of robots in an indoor environment to remain perfectly focused. The thesis demonstrates the effectiveness of ultrasound-based systems and highlights the potential of ubiquitous off-the-shelf hardware for the development of localization systems

Full textAbstract:
TSPO est une petite protéine membranaire translocatrice, ubiquitaire, composée de cinq hélices-α transmembranaires. Chez les mammifères, elle est principalement localisée dans la membrane externe des mitochondries, où elle jouerait un rôle dans le transport du cholestérol et la voie de synthèse des stéroïdes. Cette protéine présente un intérêt pharmacologique majeur en raison de sa forte affinité pour de nombreux ligands utilisés comme marqueurs de l'inflammation en neuro-imagerie. La seule structure atomique connue des TSPOs de mammifères est la structure RMN (2MGY.PDB) de la TSPO de souris (mTSPO). Cependant, cette structure est controversée, car obtenue en repliant la protéine dans une concentration forte de détergent DPC et en présence du ligand (R)-PK11195, qui la rigidifie fortement. En l'absence de ligand, la structure de mTSPO est trop flexible pour être résolue par RMN. De plus, à ce jour, aucune condition amphiphile n'a permis de cristalliser les TSPOs de mammifères, avec ou sans ligand, contrairement aux TSPOs bactériennes.L'objectif de cette étude est de déterminer, par une approche structure/fonction, l'effet de différents environnements amphiphiles sur la structure de mTSPO en condition “apo” (i.e. sans ligand). Nous avons sondé sa structure en solution à différentes échelles par des techniques de diffusion de rayonnement et de spectroscopie optique. En particulier, la diffusion de rayons X et de neutrons aux petits angles (SAXS et SANS), combinée à la chromatographie d'exclusion stérique (SEC), la variation de contraste en SANS et la modélisation ab initio, a permis d'obtenir la conformation du complexe entier mTSPO/amphiphiles et de sonder spécifiquement celles de la protéine et de la bouée d'amphiphiles. La quantité de molécules d'amphiphiles associés à mTSPO, mesurée par MALLS, a permis de valider les modèles proposés. L'effet de l'environnement sur l'affinité du ligand a été mesuré par thermophorèse à micro-échelle (MST).L'apo-mTSPO, produite par voie recombinante dans les corps d'inclusion de la bactérie E. coli, est partiellement dépliée suite à son extraction par le SDS. Nous montrons que la protéine se replie en DPC à la fois au niveau local (augmentation significative de la quantité et des interactions des hélices-α et de la fluorescence des tryptophanes) et au niveau tridimensionnel avec une conformation “apo” plus étendue que la structure RMN 2MGY.PDB. En ajoutant des phospholipides DMPC, pour obtenir un environnement de bicelles mixtes DMPC:DPC partiellement biomimétique, l'apo-mTSPO se structure davantage : la quantité d'hélices-α et leurs interactions augmentent significativement, ainsi que la fluorescence des tryptophanes. Ce repliement est associé à une augmentation significative de l'affinité de la protéine pour le ligand (R)-PK11195 (0.9 µM) comparée à celle en DPC (70 µM) et SDS (absence d'affinité). Nous démontrons ainsi la pertinence de l'utilisation de bicelles DMPC:DPC pour l'étude en solution des protéines membranaires et confirmons le rôle crucial des lipides dans la structure et la fonction de mTSPO. Enfin, nous montrons que cet environnement est favorable à la cristallisation de l'apo-mTSPO et à la reconstitution de la protéine dans des nanodisques de DMPC.Pour comparer ces résultats avec une protéine exprimée en condition native, nous avons développé un nouveau protocole de production de mTSPO en levures. Nous avons réussi à purifier la protéine en condition “apo” en DDM, un détergent connu pour solubiliser les protéines correctement repliées tout en conservant des lipides membranaires associés. Ces travaux de thèse (i) contribuent à une meilleure compréhension de la structure/fonction de mTSPO dans différents environnements amphiphiles, pour déterminer les conditions optimales à des études structurales à plus haute résolution, et (ii) constituent un apport méthodologique significatif pour l'étude des protéines membranaires en solution<br>TSPO is a small, ubiquitous, translocator membrane protein composed of five transmembrane α-helices. In mammals, it is primarily located in the outer mitochondrial membrane, where it is believed to play a role in cholesterol transport and steroid synthesis pathways. This protein has significant pharmacological interest due to its affinity for various ligands used as markers of inflammation in neuroimaging. The only known atomic structure of mammalian TSPOs is the NMR structure (2MGY.PDB) of mouse TSPO (mTSPO). However, this structure is controversial as it was obtained by refolding the protein using a high concentration of DPC and in the presence of the ligand (R)-PK11195, that stiffens it significantly. In the absence of ligand, the structure of mTSPO is too flexible to be resolved by NMR. Furthermore, to date, no amphiphilic condition has allowed the crystallization of mammalian TSPOs, with and without ligand, unlike bacterial TSPOs.The aim of the present study is to determine, using a structure/function approach, the effect of different amphiphilic environments on the structure of apo-mTSPO (i.e. without the ligand). We investigated mTSPO's structure in solution at different scales using radiation scattering and optical spectroscopy techniques. Small-angle X-ray and neutron scattering (SAXS, SANS), combined with size-exclusion chromatography (SEC), contrast variation in SANS, and ab initio modeling, allowed us to obtain the conformation of the entire mTSPO/amphiphile complex and to specifically probe those of the protein and the amphiphilic belt within the complex. The quantity of amphiphile molecules associated with mTSPO, measured by MALS, allowed the validation of the proposed models. The effect of the environment on ligand affinity was measured by microscale thermophoresis (MST).The apo-mTSPO, produced by a recombinant way in E.coli bacteria inclusion bodies, is partially unfolded following its extraction by SDS. We show that the protein refolds in DPC, both locally (significant increase of content and interactions of α-helices and in tryptophan fluorescence) and three-dimensionally, with a more extended "apo" conformation than the NMR structure 2MGY.PDB. Adding DMPC phospholipids to create a partially biomimetic environment of mixed DMPC:DPC bicelles further structures apo-mTSPO: the quantity and interactions of α-helices, as well as tryptophan fluorescence, increase significantly. This refolding is associated with a significant increase in the protein's affinity for the ligand (R)-PK11195 (0.9 μM) compared to that in DPC (70 μM) and SDS (no affinity). Thus, we demonstrate the relevance of using DMPC:DPC bicelles for studying membrane proteins in solution and confirm the crucial role of lipids in the structure and function of mTSPO. Finally, we show that this environment is favorable for the crystallization of apo-mTSPO and for reconstituting the protein in DMPC nanodiscs.To compare these results with a protein expressed under native conditions, we developed a new protocol for producing mTSPO in yeast cells. We managed to purify the protein in “apo” condition in DDM, a detergent known for solubilizing properly folded proteins, while retaining associated membrane lipids.This thesis work (i) contributes to a better understanding of the structure/function of mTSPO in different amphiphilic environments to determine optimal conditions for higher-resolution structural studies, and (ii) provides a significant methodological contribution to the study of membrane proteins in solution

Business Administration/Interdisciplinary<br>D.B.A.<br>New capabilities required to succeed in the new Cloud environment represent a radical change for software companies, which have to transition from selling on-the-premises software products to providing subscription-based cloud services (aka Software-as-a-Service or SaaS). While emerging SaaS vendors have led the exponential growth of the market, the traditional software industry has been disrupted. The purpose of this dissertation is to analyze which capabilities are driving the performance of software firms in today’s cloud-computing environment by drawing upon the resource-based view (RBV) of the firm. What is the optimum spending across the primary firm capabilities (e.g., service delivery, R&D, marketing and sales) to maximize financial performance? This dissertation focuses on publicly-traded SaaS companies using publicly-available information from financial databases, corporate investor relations materials, and industry research. It is comprised of two essays. The first essay is a quantitative study based on secondary data. The second essay includes an extensive literature review, an analysis of in-depth interviews of practitioners, and mini case studies. Together, the essays contribute to RBV theory and provide useful insights to help assess the quality of execution of SaaS growth strategies and improve financial planning and performance in the software industry for the cloud computing environment. Although the results come from firms in the SaaS industry, the findings from this study could cautiously generalize to firms in other emerging technology industries. The dissertation concludes with a detailed agenda for future research.<br>Temple University--Theses

Full textAbstract:
This thesis is based on cross-sectional data analyses by using Ordinary Least Squares (OLS) Method in order to determine the main drivers of the environmental performance and specifically the effects of environmental audits conducted by
Supreme Audit Institutions (SAIs) on sustainable development. Two general models are employed throughout the study that have the Environmental Performance Index
(EPI) as dependent variable and various sub-models for different income groups are produced to observe the individual and interactive effects of explanatory variables.
First model includes 150 countries regressing their EPI scores on income, population, literacy rate and indicators of the strength of institutional structure such as corruption
perceptions index or government effectiveness score. Then, second model which comprises 52 countries introduces the number of environmental audit reports as a new explanatory variable. Principal Component Analysis (PCA) is also applied to highly correlated variables and the models are reestimated. The results indicate that well functioning environmental management systems and resulting positive effects on
the environmental performance can only be attained through strengthened governmental institutions with high transparency and accountability as well as rigid
implementation of the related regulations. More specifically, environmental audit reports generated by SAIs are of vital importance for especially improving the environmental management systems of the developing countries.

Amyotrophic lateral sclerosis (ALS) is characterized by the progressive degeneration of upper and lower motor neurons. The majority of ALS patients are considered of unknown origin, termed sporadic, and are largely assumed to arise from environmental insults. Despite this, research to date has been heavily focused on genetic models of the disease, which represent 10% of ALS cases. Research has made disappointing progress with elucidating disease initiating mechanisms and therapeutic translation in patients. Sporadic ALS (sALS) models may provide substantially more applicable insight into disease pathogenesis, however there is currently a lack of reliable and effective models. Zebrafish offer promising advantages to investigating ALS, with highly conserved biological processes to humans, including genes implicated in human neurodegenerative diseases. Further, they can be used for high throughput toxicity screening and are optically transparent as embryos to allow for high resolution imaging in vivo. Here, we investigate using zebrafish as a model for screening for motor neuron defects and hypothesize that exposure to particular environmental toxins can be used to induce ALS-like hallmarks in a zebrafish model. We find that the zebrafish is an efficient and effective model for screening motor neuron toxicity induced by neurotoxins and Bisphenol A (BPA) exposure has a clear dose-response effect on reduced motor neuron length and branching in embryos at 48 hours post fertilization (hpf). We provide evidence that motor axon length as a valid surrogate marker of motor neuron degeneration by confirming the conventional method of measuring the length from a sagittal view in defective motor axons represents their true length in 3 dimensions, and confirm that reduced motor axon length is associated with increased motor neuron death. Further, BPA exposure results in an ALS-like phenotype with reduced motor function at 24 and 48 hpf, reduced neuromuscular junction integrity and microglia activation in embryos at 48 hpf. Together, these results show that the zebrafish model is advantageous for screening toxin-induced motor neuron death and can be used as a valid model of sALS. This research can be extended to confirm ALS-associated neurotoxins and provide insight into pathogenic mechanisms of sALS.<br>Graduate and Postdoctoral Studies<br>Graduate

Nos últimos anos tem havido um aumento no estudo da qualidade do ar interno relacionado aos sistemas de ventilação mecânica e condicionamento do ar. Isso é especialmente fundamental em hospitais, onde a transmissão da contaminação pelo ar é considerada uma das principais causas de aquisição de doenças por pacientes, profissionais de saúde e visitantes. Além disso, essas instituições por abrigarem diversos setores, cada um com uma especificidade e função, exigem diferentes condições de conforto ambiental, sob os aspectos higrotérmico e de qualidade do ar, além do acústico e luminoso. Com o objetivo de avaliar a qualidade o ar, sob os parâmetros de conforto térmico e da concentração de dióxido de carbono em ambientes hospitalares climatizados artificialmente, realizou-se uma investigação de campo em salas de espera e salas de cirurgias de uma amostra de seis edifícios hospitalares na cidade de São Paulo e região metropolitana. Para coleta dos dados foram utilizados instrumentos de monitoramento, portáteis e de elevada precisão, adequados para a realização da pesquisa. Os resultados obtidos a partir da análise desses dados apontaram relevantes problemas relacionados ao conforto e a qualidade do ar. Dentre esses problemas, destacam-se a ausência de controle do diferencial de pressão entre as salas de cirurgias e os corredores; a divergência entre as temperaturas operativas ideais para promoção do conforto térmico para grupos de pessoas com diferentes vestimentas e nível de atividade, ocupando um mesmo ambiente, no caso, as salas de cirurgias; a insuficiência de renovação de ar, especialmente nas salas de espera equipadas com o sistema de climatização do tipo split-system; além da ausência de padronização entre os critérios dos referenciais técnicos mais adotados. Sob esses aspectos, percebeu-se a necessidade de melhoria do conhecimento da interação entre os ocupantes e o ambiente, especialmente naqueles onde o controle se faz necessário para a promoção da saúde.<br>In recent years has been increased interest in thermal comfort and air quality of indoor environments related to mechanical ventilation systems and air conditioning. This is especially crucial in hospitals where contaminated air transmission is considered a major cause of acquiring disease for patients, health care professionals and visitors. Moreover, these institutions having different sectors, each one with a speciality and function, require different conditions of environmental comfort, in terms of hygrothermal, air quality, acoustic and luminous aspects. In order to evaluate the air quality under the parameters of thermal comfort and carbon dioxide concentration in air conditioning hospital environments, it was carried out a field investigation in waiting rooms and operating rooms in six hospitals in São Paulo and metropolitan region. For data collection were used portable monitoring devices, suitable for research. The results from data analysis indicated significant problems related to thermal comfort and indoor air quality. Among these problems, it can be highlighted the lack of the differential pressure control between the operating rooms and corridors; the divergence among the optimal operative temperatures to provide thermal comfort for different groups of people with different clothing and activity level, occupying the same environment, in this case, the operating rooms; the disregard with the air changes required, especially in waiting rooms equipped with the splitsystem; besides the lack of standardization among the technical references criteria often used. Under these aspects, it is necessary to improve the knowledge of the interaction between the occupants and the environment, especially where the environmental control is decisive to promote the health.

This paper's purpose is a multiparty Service Level Agreement (SLA) for cloud computing auditing. Audits are performed on the IaaS provider, IaaS contractor (SaaS provider) and SaaS client. The objective is to audit the cloud environment problems, internally and externally, in an unquestionable way by the parties. The proposal uses inspectors (auditing collector agents) and an independent auditor (third party), capable of identifying SLA deviations through information collected in the parties' environments. The results show that it is possible to audit and diagnose problems in the cloud by combining information from the parties with the independent auditing, in addition to avoiding conflicts of interest of the inspectors.

Full textAbstract:
Over the years, Software as a Service (SaaS) has become a common delivery model for many applications. In cloud applications, a huge volume and variety of data can be generated and they can be available for consumption by DaaS (Data as a Service). For this, the data provided by DaaS can be stored in a non-structured (e.g. text), semi-structured (e.g. XML, JSON) or structured format (e.g. Relational Database). However, the access of that kind of DaaS, in a transparent manner, needs substantial efforts due to the lack of interoperability between SaaS and DaaS. In this paper, we propose a new enhanced version of MIDAS, middleware to provide seamlessly and independently interoperability between SaaS and DaaS. First, this new version of MIDAS allows both semi-structure and structure data format from SaaS. It mediates queries from NoSQL (e.g. MongoDB) and SQL (MySQL) databases. Secondly, it was enhanced with Join operations, both in SQL and in NOSQL statements. And lastly, other formats were added for the DaaS to fit SaaS requests, such as JSON, XML, and CSV formats. To evaluate this new version of our middleware, we provide three types of experiments to cover critical issues such as execution time, the overhead of our approach, and scalability of MIDAS. Our results show the effectiveness of our approach to tackling interoperability issues in cloud computing environments.

Full textAbstract:
This Evidence Snapshot is an updated rapid review of current knowledge about aerosol transmission of COVID-19. The original review was completed in August 2020 and this updated review in October 2020. The updated review found that the weight of evidence was that aerosol transmission of SARS-CoV-2 does occur. Five reviews found that the virus may spread as an aerosol. Experimental studies demonstrated aerosolisation of the virus with persistence from 90 minutes to 16 hours, and evidence for horizontal transmission was found for ranges from two to eight metres. Environmental sampling studies typically found viral RNA both in the air and on air vents. Eight out of ten investigations of outbreaks reviewed found that transmission occurred without close direct contact. Risk of transmission was thought to be associated with shared indoor space, closed air recirculation and singing. Eighteen articles were reviewed in the updated report in addition to the nineteen articles in the original report, for a total of thirty-seven articles.

Full textAbstract:
The South Atlantic Coastal Study (SACS) was completed by the US Army Corps of Engineers to quantify storm surge and wave hazards allowing for the expansion of the Coastal Hazards System (CHS) to the South Atlantic Division (SAD) domain. The goal of the CHS-SACS was to quantify coastal storm hazards for present conditions and future sea level rise (SLR) scenarios to aid in reducing flooding risk and increasing resiliency in coastal environments. CHS-SACS was completed for three regions within the SAD domain, and this report focuses on the Coastal Hazards System–Puerto Rico and US Virgin Islands (CHS-PR). This study applied the CHS Probabilistic Coastal Hazard Analysis (PCHA) framework for quantifying tropical cyclone (TC) responses, leveraging new atmospheric and hydrodynamic numerical model simulations of synthetic TCs developed explicitly for the CHS-PR region. This report focuses on documenting the PCHA conducted for CHS-PR, including the characterization of storm climate, storm sampling, storm recurrence rate estimation, marginal distributions, correlation and dependence structure of TC atmospheric-forcing parameters, development of augmented storm suites, and assignment of discrete storm weights to the synthetic TCs. As part of CHS-PR, coastal hazards were estimated for annual exceedance frequencies over the range of 10 yr⁻¹ to 10⁻⁴ yr⁻¹.

Full textAbstract:
The objective of this project was to determine if portable friction testers could be used for friction measurements on compacted snow and ice surfaces. First, the effect of cold temperatures on the operation, consistency, and accuracy of commercially available portable pavement friction measuring tools was evaluated. Tests entailed a series of experiments in a controlled cold room environment. Two portable fixed slip continuous measurement devices and one deceleration spot measurement device were evaluated. The controlled temperature testing determined how ambient temperature and duration of exposure can affect results, but that with care, the devices could be operated in conditions as cold as ˗25°C. This was followed by using one of the devices on outdoor testing on snow, ice, and asphalt surfaces and compared the portable tester to the well-known SAAB vehicle runway friction tester. Results showed good agreement between the portable tester and the SAAB Friction tester, providing validation for the operational use of a portable tester on frozen surfaces.

Currently, it is important in Ukraine to harmonize cloud technologies application with European and world scientific initiatives. Need to modernize preparation of future PhDs is caused by challenges of new information, globalized society and digital transformation of all spheres of life, including education and science. The research was aimed to determine features of cloud services application in preparation of future PhDs. Concepts of “cloud computing”, “cloud technologies”, “cloud learning technologies”, “cloud services”, “cloud oriented environment” were analyzed. Experience of cloud technologies and their services application in educational and scientific space in researches of foreign and Ukrainian students was considered. Ukrainian experience in preparation of future PhD of various specialties with cloud services application was analyzed. It was emphasized that approaches improving to preparation of future PhDs based on cloud services application would increase their level of digital competence. It is recommended to include a separate course or module of specific discipline on work with cloud technologies and services during preparation of future PhDs. It is important to improve disciplines and tools content to support education process. It can be learning of disciplines using cloud technologies or services by future PhD’s. Also, cloud services application to support scientific and scientific-organizational activities will increase level of organization and implementation of scientific research. It is important to create cloud-oriented environment for preparation of future PhDs in higher education and research institutions. Making cloud-oriented educational and scientific environment should be based on principles of open education. It is recommended to use cloud-based platforms and services (G Suite for Education; Microsoft Office 365; specialized SaaS (CoCalc or other)).

Full textAbstract:
Submerged aquatic vegetation (SAV) growing in estuarine and coastal marine systems provides crucial ecosystem functions ranging from sediment stabilization to habitat and food for specific species. SAV systems, however, are sensitive to a number of environmental factors, both anthropogenic and natural. The most common limiting factors are light limitation, water quality, and salinity, as reported widely across the literature. These factors are controlled by a number of complex processes, however, varying greatly between systems and SAV populations. This report seeks to conduct an exhaustive examination of factors influencing estuarine and coastal marine SAV habitats and find the common threads that tie these ecosystems together. Studies relating SAV habitats in the United States to a variety of factors are reviewed here, including geomorphological and bathymetric characteristics, sediment dynamics, sedimentological characteristics, and water quality, as well as hydrologic regime and weather. Tools and methods used to assess each of these important factors are also reviewed. A better understanding of fundamental environmental factors that control SAV growth will provide crucial information for coastal restoration and engineering project planning in areas populated by SAVs.

Physical property testing found that 14 of the borings were non-cohesive sandy materials that may be suitable for potential beach renourishment or berm construction. The remaining 20 borings had mud contents sufficient enough to result in cohesive behavior. A subset of six of these materials from across the geographic region were further evaluated to characterize their erosion behavior. Following a self-weight consolidation period of 30 days, erosion testing showed that the tested cohesive sediments had critical shear stress values that ranged from 1.7 Pa to 2.9 Pa, suggesting that these sediments would likely be resistant to erosion in most wetland environments after placement. Additionally, the cohesive sediments were found to produce gravel-sized mud clasts. These clasts could account for 20% or more of the eroded mass and significantly reduce the amount of silts and clays incorporated in suspended plumes during and immediately following placement.
