This study evaluates radar-based target detection pipelines for both static and human subjects, analyzing the performance of variance-based and CFAR methods. It introduces new evaluation metrics, including coverage and consistency tests, and highlights the impact of different processing techniques on point cloud quality. / This thesis tackles the challenge of employing quantifiable metrics to assess the quality of point clouds generated by various distinct pipelines using TI IWR6843AOP mmWave FMCW radar. This study focuses on developing quantifiable metrics to evaluate point cloud quality for both static targets, such as the corner reflectors used in this research, and human targets. For static point targets, this study introduces metrics that combine Euclidean distance errors with range, azimuth, and elevation angle errors, providing a more comprehensive assessment compared to using Euclidean distance errors alone. For human targets, this thesis introduces metrics from two perspectives. The first focuses on coverage, employing the Euclidean distance to the human mesh surface to quantify errors between the ground truth human mesh and the point cloud. Additionally, It calculates the Euclidean distance between each point and all joints, selecting the minimum distance to determine the closest joint and evaluating the percentage of points reflected from each body segment. The second focus is on consistency. Point cloud consistency across consecutive frames is assessed by analyzing the mean and maximum intensity values and calculating Hausdorff distances to evaluate the stability of the point cloud distribution. / Thesis / Master of Applied Science (MASc) / This thesis explores ways to measure the accuracy and reliability of a 3D representation called a point cloud created from radar data. Radar, like the kind used in car driving assist features, can detect objects and people by transmitting high-frequency radio waves. This thesis focuses on developing evaluation methods to assess how closely point clouds match objects or people in the real world. Experiments were conducted in a laboratory environment to validate these evalu- ation methods. Static corner reflectors, known for their strong radar signal reflection, were used to assess the system’s performance in capturing exact positions. Addition- ally, the study examined the quality of point clouds in representing moving human subjects. The objective is to develop a set of metrics that quantify the performance of various point cloud generation methods. These quantitative measures can improve the accuracy and reliability of the point cloud generation pipeline, thereby improving downstream applications such as indoor localization and monitoring.

However, the vast amount of data has generated many question marks, so there is a great need to understand how the translation process of social media activities is proceeding to have the ability to understand the effectiveness of the activities. Purpose: The purpose is to describe the translation process regarding the evaluation of social media activities. Research Question: How is the translation process described concerning social media activities? Methodology: The research is founded upon a qualitative approach with a descriptive purpose. It includes multiple-case studies and the data was collected through six semi-structured interviews. The result was derived by descriptions, categorizations and combination of the data. Conclusion: Despite having a fairly stable process including KPIs, metrics, data collection and analysis, there is no general way of translating social media indicators. Every translation process is dependent upon whom the client is, and what the objectives are, so it is difficult to describe the process in detail. However, the above-mentioned process can be viewed as an overall approach.

Purpose –Comparing the accessibility of e-commerce for General Merchandise, between major retailers and novelties, in the conformance of web accessibility guidelines, and the implementation of rich internet applications specifications. So that to figure out whether the differences exist between them, if so, what are the differences, and analyzing upcoming e-commerce and established e-commerce.  Method – The descriptive and quantitative case studies were used to evaluated 45 websites respectively from major retailers and novelties in General Merchandise of e-commerce, where sample websites were selected from Alexa’s rank lists. Then the WAVE tool, Accessibility Quantitative Metric (WAQM), and Fona assessment were applied for analyzing cases for representing the accessibilities and answering the research questions of purpose.  Findings – ARIA specifications as a kind of technological solution really had positive functions on web accessibility when only focusing on accessibility guidelines, because the novelty websites with less ARIA attributes resulting in lower accessibility levels generally, even though there were also many other elements that can affect accessibility.  Implications – In the main branch of General Merchandise, the degree of web accessibility in major retailer websites was better than that in novelties, which means as far as e-commerce is concerned, the accessibility of mature websites that had been established for a long time was contemporarily stronger than that of new websites with creative products.  Limitations – From the perspective of the sample, there were limitations in sample sources, size, websites languages, while in the technical aspect, the evaluation of dynamic contents just aims at keyboard navigation, and the tool of Fona assessment also had restrictions.
