In resource requirement part, fundamental estimation filters are compared according to their CPU usage, memory needs and complexity. The best fundamental estimation filter which needs very low resources is the Alpha-Beta-Filter. In performance evaluation part of this thesis, performance metrics used are: Root-Mean-Square Error (RMSE), Average Euclidean Error (AEE), Geometric Average Error (GAE) and normalized form of these. The normalized form of performance metrics makes measure of error independent of range and the length of trajectory. Fundamental estimation filters and performance metrics are implemented in MATLAB. MONTE CARLO simulation method and 6 different air trajectories are used for testing. Test results show that performance of fundamental estimation filters varies according to trajectory and target dynamics used in constructing the filter. Consequently, filter performance is application-dependent. Therefore, before choosing an estimation filter, most probable target dynamics, hardware resources and acceptable error level should be investigated. An estimation filter which matches these requirements will be &lsquo

Virtualized datacenter administrators would like to consolidate virtual machines (VMs) onto as few physical hosts as possible in order to decrease costs, but must leave enough physical resources for each VM to meet application service level objectives (SLOs). The threshold between good and bad performance in terms of resource settings, however, is hard to determine and rarely static due to changing workloads and resource usage. Thus, in order to avoid SLO violations, system administrators must err on the side of caution by running fewer VMs per host than necessary or setting reservations, which prevents resources from being shared. To ameliorate this situation, we are working to design and implement a system that automatically monitors VM-level metrics to predict impending application SLO violations, and takes appropriate action to prevent the SLO violation from occurring. So far we have implemented the performance prediction, which is detailed in this document, while the preventative actions are left as future work. We created a three-stage pipeline in order to achieve scalable performance prediction. The three stages are prediction, which predicts future VM ESX performance counter values based on current time-series data; aggregation, which aggregates the predicted VM metrics into a single set of global metrics; and finally classification, which for each VM classifies its performance as good or bad based on the predicted VM counters and the predicted global state. Prediction of each counter is performed by a least-squares linear fit, aggregation is performed simply by summing each counter across all VMs, and classification is performed using a support vector machine (SVM) for each application. In addition, we created an experimental system running a MongoDB instance in order to test and evaluate our pipeline implementation. Our results on this experimental system are promising, but further research will be necessary before applying these techniques to a production system.

Pełny tekst źródłaThis research establishes metrics for determining overall Navy secondary inventory forecasting accuracy when compared to actual demands at the Naval Inventory Control Point (NAVICP). Specifically, two performance metrics are introduced: the average performance index (API) and the median absolute deviation performance index (MPI). API measures forecasting accuracy of secondary inventory when compared against demand or forecast performance over a four-quarter period. MPI measures the quarterly variability of forecast errors over the same period. The API and MPI metrics allow for the identification of poorly forecasted NAVICP secondary inventory items. The metrics can be applied to entire inventories or subsets of items based on type, demand, or cost. In addition, the API metric can be used to show overall inventory performance, providing NAVICP with a graphical means to assess forecasting performance improvements (or degradations) over time. The new forecasting accuracy methods developed in this research will allow the Navy to continually gauge the overall health of their inventory management practices and provide a method for improving forecasting accuracy. Additionally, they will assist NAVICP in complying with DoD directives that require NAVICP to monitor and continually develop improvements to inventory management practices.

NASA astronauts undergo many hours of formal training and self-study to gain proficiency in space teleoperation tasks. After each lesson, instructors score an astronaut's performance in several broad skill categories, including 'General Situational Awareness', 'Maneuvers/Task Performance', and 'Hand- Controller Techniques'. A plus, check, or minus indicates that the student is ahead of, at, or behind the expected skill level. The scoring of the final evaluation for a robotics training course is also largely subjective, with the instructor designating an integer score for the student between 1 (Unsatisfactory) and 5 (Strong) in the same skill categories. This thesis research project was designed to: (1) consider the variety of quantitative metrics that could be embedded into a space robotics training simulation, and (2) investigate at what point and by what means it is most constructive for performance assessment to be revealed to an operator-in-training. We reviewed the current largely qualitative space robotics performance metrics, as well as new quantitative kinematic metrics of manual control skills-including those explored thus far only in laboratory experiments-and additional measures of executive function and supervisory control performance. Kinematic metrics include quantitative measures such as rate of change of linear and rotational acceleration. Potential measures of executive function and supervisory control include camera selection and clearance monitoring. To instantiate our ideas, we chose a specific "fly-to" space telerobotics task taught in the early phases of NASA Generic Robotics Training (GRT) and developed a pilot training experiment (n=16) using our virtual robotics training workstation. Our goal was to evaluate potential performance metrics designed to encourage use of multi-axis control, and to compare real-time ("live") performance feedback alternatives (live visual vs. live aural vs. none). Movement time decreased and multi-axis and bimanual control use gradually increased across trials. All subjects had the opportunity to view post-trial performance feedback including these metrics. Although our subjects overwhelmingly preferred the live, visual feedback condition, no reliable additional effects of live feedback condition were found, except perhaps among the more experienced subjects. However, the experiment demonstrated that embedded performance metrics potentially could quantify and improve some important aspects of GRT evaluations.

In recent years the American industrial landscape has undergone tremendous change as companies have worked to adopt Lean practices. This transformation has been difficult, but necessary, as American companies work to remain competitive with foreign competitors. A key enabler of these Lean transformations has been the use of visual metrics to communicate how a process has performed as well as to set goals for future performance. The challenge is to first identify what data is available and then create metrics that encourage and reward Lean behaviors. This thesis explores the introduction of visual metrics for a part inspection process at the Raytheon Company. Prior to the introduction of these metrics, there was limited ability to determine how the process was performing. As a result, downstream customers were able to track when a part entered the inspection process but were unable to predict when the inspection would be completed. This introduced a risk to the process and created a sense of frustration through the facility. The visual metrics for the inspection area were created on a series of visual dashboards that display common Lean metrics, such as cycle time and backlog (or work-in-process). Through these dashboards the area will be able to understand how it is performing and initiate continuous improvement projects to improve performance.

Pełny tekst źródłaThe Navys approach to planning and executing Chief of Naval Operations maintenance availabilities has undergone significant changes since 2006. The adoption of unique lean initiatives and defined project management fundamentals have guided shipyard and project leadership as they manage scheduled industrial maintenance for ships and submarines. These business practices have resulted in performance measurement and control data being gathered for shipyard management to use as they analyze availability performance. This thesis reports on the results of exploratory analyses of these data to evaluate associations and trends pertaining to cost and schedule performance since the inception of the lean initiative. The studys analyses suggest that numerous performance metrics display trends which suggest availability performance is improving over the defined lean initiative time frame; that several metrics are functions of the length of the individual availability and require appropriate weighting considerations; and that average weekly interim production bow wave metrics evaluated early in an availability may have predictive abilities concerning availability completion success.

Pełny tekst źródłaNär man använder grafiska gränssnitt upplevs lång responstid och fördröjning som de främsta problemen. Dessa problem är frustrerande och ger användare en negativ syn på både det grafiska gränssnittet och företaget som skapat det.Det är viktigt att grafiska gränssnitt är intuitiva, lättanvända och lättfattliga samtidigt som de levererar hög prestanda. Det finns faktorer som påverkar dessa egenskaper som är utanför programmerarnas händer, t.ex. användarens internetuppkoppling och hårdvara. Eftersom varje användare har olika kombinationer av internetuppkoppling och hårdvara är det svårt att tillfredsställa alla och samtidigt tillhandahålla ett intuitivt och responsivt gränssnitt.Målet med denna studie är att hitta ett sätt att övervaka prestandan av ett grafiskt gränssnitt där begreppet prestanda omfattar responsiviteten och hastigheten av den grafiska renderingen, och genom detta möjliggöra förbättring av responstider och renderingstider.Ett ramverk som övervakar prestandan av ett grafiskt gränssnitt utvecklades. Ramverket samlar in relevant prestandamässig data om det grafiska gränssnittet och sparar datan i en databas. Datan som sparats kan sedan bli manuellt analyserad av utvecklare för att hitta svagheter i systemets prestanda. Detta uppnås utan att störa det grafiska gränssnittet och utan att ha någon negativ påverkan på användarupplevelsen.

Moody, Seth S. "Development of Dynamic Thermal Performance Metrics For Eco-roof Systems". Thesis, Portland State University, 2013. http://pqdtopen.proquest.com/#viewpdf?dispub=1535587.
Pełny tekst źródłaIn order to obtain credit for an eco-roof in building energy load calculations the steady state and time-varying thermal properties (thermal mass with evapotranspiration) must be fully understood. The following study presents results of experimentation and modeling in an effort to develop dynamic thermal mass performance metrics for eco-roof systems. The work is focused on understanding the thermal parameters (foliage & soil) of an eco-roof, further validation of the EnergyPlus Green Roof Module and development of a standardized metric for assessing the time-varying thermal benefits of eco-roof systems that can be applied across building types and climate zones.
Eco-roof foliage, soil and weather parameters were continuously collected at the Green Roof Integrated PhotoVoltaic (GRIPV) project from 01/20/2011 to 08/28/2011. The parameters were used to develop an EnergyPlus eco-roof validation model. The validated eco-roof model was then used to estimate the Dynamic Benefit for Massive System (DBMS) in 4 climate-locations: Portland Oregon, Chicago Illinois, Atlanta Georgia and Houston Texas.
GRIPV30 (GRIPV soil with 30% soil organic matter) was compared to 12 previously tested eco-roof soils. GRIPV30 reduced dry soil conductivity by 50%, increased field capacity by 21% and reduced dry soil mass per unit volume by 60%. GRIPV30 soil had low conductivity at all moisture contents and high heat capacity at moderate and high moisture content. The characteristics of the GRIPV30 soil make it a good choice for moisture retention and reduction of heat flux, improved thermal mass (heat storage) when integrating an eco-roof with a building.
Eco-roof model validation was performed with constant seasonal moisture driven soil properties and resulted in acceptable measured - modeled eco-roof temperature validation. LAI has a large impact on how the Green Roof Module calculates the eco-roof energy balance with a higher impact on daytime (measured - modeled) soil temperature differential and most significant during summer.
DBMS modeling found the mild climates of Atlanta Georgia and Houston Texas with eco-roof annual DBMS of 1.03, 3% performance improvement above the standard building, based on cooling, heating and fan energy consumption. The Chicago Illinois climate with severe winter and mild spring/summer/fall has an annual DBMS of 1.01. The moderate Portland Oregon climate has a below standard DBMS of 0.97.

Software as a Service (SaaS) delivery model has become widespread. This deployment model changes the economics of software delivery but also has an impact on development. Releasing updates to customers is immediate and the development, product and marketing teams have access to customer usage information. These dynamics create a fast feedback loop between developments to customers. To fully leverage this feedback loop the right metrics need to be set. Typically SaaS applications are a collection of features. The product is divided between development teams according to features and customers access the service through features. Thus a framework that measure feature performance is valuable. This thesis provides a framework for measuring the performance of software as a service (SaaS) product features in order to prioritize development efforts. The case is based on empirical data from HubSpot and it is generalized to provide a framework applicable to other companies with large scale software offerings and distributed development. Firstly, relative value is measured by the impact that each feature has on customer acquisition and retention. Secondly, feature value is compared to feature cost and specifically development investment to determine feature profitability. Thirdly, feature sensitivity is measured. Feature sensitivity is defined as the effect a fixed amount of development investment has on value in a given time. Fourthly, features are segmented according to their location relative to the value to cost trend line into: most valuable features, outperforming, under-performing and fledglings. Finally, results are analyzed to determine future action. Maintenance and bug fixes are prioritized according to feature value. Product enhancements are prioritized according to sensitivity with special attention to fledglings. Under-performing features are either put on "life-support", terminated or overhauled.

Pełny tekst źródłaAtt exakt definiera och mäta prestation är en komplex process för de flesta företag, men ändå avgörande för korrekt distribution av resurser och för att uppnå en förståelse för gemensamma mål mellan affärsenheter. Trots den stora mängd data som finns tillgänglig för de flesta moderna företag idag, väljs mått av prestationer ofta baserat på expertis, tradition eller till och med magkänsla. I detta examensarbete föreslås en datadriven strategi i form av ett statistiskt ramverk för utvärdering och val av prestationsmått. Ramverkets struktur baseras på en dimensionsreducerande metod, känd som (eng.) feature selection, för tidsserier och som i sökningen efter relevanta prestationsmått använder sig av en prediktionsalgoritm för tidsserier. För att designa ett komplett ramverk utförs experiment som utforskar moderna prediktionsalgoritmer för tidsserier i kombination med två olika dimensionsreducerande metoder. Resultaten visar att för prestationsmått baserade på den verkliga data som använts i detta examensarbete, så utgörs det bästa ramverket utav den dimensionsreducerande metoden som använder sig av filtrering i kombination med en prediktionsalgoritm för univariata tidsserier.

Buildings account for over 40% of the energy consumption in the United States, nearly 40% of which is attributed to lighting. The selection of a fenestration system for a building is a critical decision as it offsets electric lighting use as well as impacts energy performance through heating and cooling systems. Further, the fenestration system contributes to both occupant comfort and ambiance of the space. Complex Fenestration Systems (CFS) address these factors with a variety of innovative technologies but the language to describe, discuss, and compare them does not exist. Existing traditional metrics for fenestration systems are unable to reveal the benefits that characterize complex fenestration systems because they are rigid, do not reflect annual performance, and were developed for a different purpose. The framework presented in this research offers a solution to this problem by using an annual climate-based methodology to provide a comprehensive evaluation of a system by incorporating three of the most relevant performance aspects: energy efficiency, occupant visual comfort, and ability to view through. Three metrics, the Relative Energy Impact (REI), the Extent of Comfortable Daylight (ECD), and the View Through Potential (VTP), were derived from these three criteria to express, in relative terms, a fagade's contribution to building energy use, comfortable daylight conditions, and the degree of transparency, respectively. Several practical matters were considered when developing a policy-relevant set of metrics, including both ease of calculation for manufacturers and usability for consumers. As such, the calculation methodology evolved from its initial proposal into a simplified approach, analytical where possible, and into a label-like concept for visual representation. These metrics are intended to exist as a mechanism by which manufacturers can evaluate and compare facade systems, provide high-level intuition of relative performance for designers and contractors, and enable the balance of performance objectives based on user preference. Ultimately, the creation of this comprehensive language is intended to stimulate innovation in fenestration systems and encourage their use in both new and retrofit building applications.

Pełny tekst źródłaThe Telecommunications industry is a “world” where services like data, voice and value-added services must be available at anytime, anywhere. Because of this requirement, it became a really aggressive market, where the least detail can make the difference. One of the details that can be really differentiating is related to network management. With all the changes and rapid evolution of telecommunications, this can be considered a critically important point. An efficient and optimized network management can save time and money and that is why it is a mandatory aspect in this market. There are two different paths to be considered: long term management, which consists in saving less detailed data for long periods of time, and real time management that allows much more detailed information for narrower time frame. Because of database and costs related issues, only one of them must be chosen and there is some important information that may become “invisible”, leading to unsolved problems that can be highly expensive. Regarding this situation, it would be extremely beneficial for the telecom operators if they could visualize both types of data, having the long term information along with the most important details of real time information in one view.
A indústria das Telecomunicações é um mundo onde os serviços de dados, voz e outros serviços importantes têm que estar disponíveis sempre e em todo o lado. Por causa dessas exigências, tornou-se um mercado extremamente agressivo, onde o menor detalhe pode fazer a diferença. Um desses detalhes diferenciadores está relacionado com a gestão da rede. Com todas as mudanças e rápida evolução das telecomunicações, este pode ser considerado um ponto crítico. Uma gestão eficiente e otimizada pode poupar tempo e dinheiro e por isso é um aspeto crucial deste mercado. Em termos de gestão e monitorização das redes, há dois caminhos a considerar: gestão a longo prazo, que consiste em salvar dados menos detalhados por longos períodos de tempo; e gestão em tempo real, que permite dados muito mais detalhados mas durante uma janela temporal consideravelmente menor. Devido a limitações ao nível da base de dados e elevados custos, apenas um deve ser escolhido, o que leva a que se perca alguma informação em qualquer dos casos. Assim, podem surgir problemas cuja resolução será complicada e dispendiosa. Posto isto, seria extremamente benéfico para as Operadoras de Telecomunicações, se pudessem analisar os dois tipos de dados, tendo a informação a longo prazo juntamente com os detalhes mais importantes em tempo real numa só aplicação.

Smart manufacturing aims at utilizing Internet of things (IoT), data analytics, cloud computing, etc. to handle varying market demand without compromising the productivity or quality in a manufacturing plant. To support these efforts, Fog manufacturing has been identified as a suitable computing architecture to handle the surge of data generated from the IoT devices. In Fog manufacturing computational tasks are completed locally through the means of interconnected computing devices called Fog nodes. However, the communication and computation resources in Fog manufacturing are limited. Therefore, its effective utilization requires optimal strategies to schedule the computational tasks and assign the computational tasks to the Fog nodes. A prerequisite for adapting such strategies is to accurately predict the performance of the Fog nodes. In this thesis, a multi-task learning methodology is adopted to predict the performance in Fog manufacturing. Specifically, since the computation flow and the data querying activities vary between the Fog nodes in practice. The metrics that reflect the performance in the Fog nodes are heterogenous in nature and cannot be effectively modeled through conventional predictive analysis. A Fog manufacturing testbed is employed to evaluate the prediction accuracies of the proposed model and benchmark models. The results show that the multi-task learning model has better prediction accuracy than the benchmarks and that it can model the heterogeneities among the Fog nodes. The proposed model can further be incorporated in scheduling and assignment strategies to effectively utilize Fog manufacturing's computational services.

Image quality assessment addresses the distortion levels and the perceptual quality of a restored or corrupted image. A plethora of metrics has been developed to that end. The usual mean of success of an image quality metric is their ability to agree with the opinions of human subjects, often represented by the mean opinion score. Despite the promising performance of some image quality metrics in predicting the mean opinion score, several problems are still unaddressed. This thesis focuses on analyzing and assessing the performance of image quality metrics. To that end, this work proposes an objective assessment criterion and considers three indicators related to the metrics: (i) robustness to local distortions; (ii) consistency in their values'; and (iii) sensitivity to distortion parameters. In addition, the implementation procedures of the proposed indicators is presented. The thesis then analyzes and assesses several image quality metrics using the developed indicators for images corrupted with Gaussian noise. This work uses both widely-used public image datasets and self-designed controlled cases to measure the performance of IQMs. The results indicate that some image quality metrics are prone to poor performance depending on the number of features. In addition, the work shows that the consistency in IQMs' values depends on the distortion level. Finally, the results highlight the sensitivity of different metrics to the Gaussian noise parameter. The objective methodology in this thesis unlocks additional insights regarding the performance of IQMs. In addition to the subjective assessment, studying the properties of IQMs outlined in the framework helps in finding a metric suitable for specific applications.

Pełny tekst źródłaAtt välja den rätta kandidaten för ett jobb kan vara en utmaning. Det finns dessutom betydliga kostnader i att rekrytera ny arbetskraft. På grund därav finns det ett behov för noggrannhet och neutralitet från en organisation vid rekrytering av ny personal. Detta examensprojekt fokuserar på restaurang och hotellbranschen. Denna branchsektor har traditionellt sett använt undermåliga rekryteringsmetoder. Till skillnad från stora företag så kan inte restauranger avvara resurser för egna rekryterare. Därtill så försvårar de primära medierna för rekrytering i sektorn jämförelser mellan relaterade lediga jobb. Denna komplexa infrastruktur skapar ett behov av en plats där både företag och arbetssökande har tillgång till en standardiserad översikt av hela arbetsmarknaden. Introduktionen av automatisering har som syfte att bemöta dessa komplexa krav och blir alltmer vanligt inom andra branscher. Speciellt med hjälp av internetbaserad rekrytering och förval av jobbkandidater. Dessa lösningar har även potentialen att minimera risken för mänsklig subjektivitet och opartiskhet vid förval av jobbkandidater. Detta examensprojekt har som syfte att minimera ineffektiviteter och fel samhörande med den nuvarande manuella rekryteringsmetoden genom att tackla två huvudproblem: takten i vilken förvalet av arbetssökande kan göras och kvaliteten av detta förval. Detta examensprojekt inleder med en diskussion och analys av relaterade arbeten inom automatiserad rekrytering för att sedan presentera en möjlig lösning för det behandlade målområdet. Denna lösning – semantisk matchning av jobb och jobbsökande - är senare utvärderad och testad i samarbete med Cheffle, ett nätverksföretag inom serviceindustrin. Detta examensprojekt avslutar med lösningsförslag för potentiell förbättring till Cheffles nuvarande system och en slutsats om genomförbarheten av automatisering inom rekrytering.
