The roofing of this building is designed with a flat green vegetation roof.

The benefits of being able to receive individualized guidance to support learning have been shown in various studies. However, most teachers are too pressured by time and budget constraints to be able to offer this. Thus, personalized learning has become a luxury that most teachers cannot provide. However, with the rapid development of digital technologies, new opportunities are arising within this field. Scalability challenges are being overcome when digital learning platforms now can collect data and use it to generate insights concerning each student’s individual progress and challenges for the teacher to access through a dashboard. The aim of this case study is to contribute to the formation of a best practice for the design of teacher-facing dashboards (TFD) to improve learning outcomes. A user-centric approach was selected to identify obstacles and areas of improvement. These were identified by conducting interviews and think-alouds to evaluate an existing dashboard designed by the language platform Astrid Education. The results and insights are demonstrated through a redesign suggestion of the dashboard along with the teacher's evaluation of it. / Många studier har påvisat positiva effekter på lärandet när språkundervisningen är anpassad till den studerandes individuella behov. Ändå har språklärare sällan möjlighet att erbjuda ett individanpassat stöd för varje elev på grund av tids- och budgetbegränsningar. Tack vare teknikens utveckling har nya möjligheter skapats inom lärandeformer. I allt större utsträckning övergår utbildning till digitala läromedel vilket medför en tillgänglighet till information om elevers kunnande och prestation. Denna data kan sammanställas och presenteras för lärare för att erbjuda en djupare förståelse för varje elevs behov. Syftet med denna studie är att bidra till bildandet av bästa praxis för dessa dataöversikter för lärare, sk. teacher-facing dashboards (TFD) med avsikt att förbättra resultaten inom språkinlärning. En användarcentrerad designmetod valdes för att identifiera begränsningar och förbättringsområden i en digital lärplattform för engelsk språkinlärning tillhörande Astrid Education. Testanvändare intervjuades och observerades. Resultat och insikter demonstrerades genom ett designförslag tillsammans med lärares utvärdering av denna.

Numerous practical applications exist where dispersed solid particles are transported within a turbulent accelerating or decelerating gaseous flow. The large density variation between phases creates the potential for significant differences in velocity known as velocity slip. Flow over a backward facing step provides a well characterized, turbulent, decelerating flow useful for measuring the relative velocities of the solid and gaseous phases in order to determine velocity slip and particle drag. Numerous investigations have been conducted to determine the gas phase velocity in a backward facing step for both laminar and turbulent flows and therefore the gas phase flow is well know and documented. Furthermore, some studies have also been conducted to determine the velocity of various sizes of spherical particles in a backward facing step and compared with their corresponding gas phase velocities. Few if any velocity measurements have been made for non-spherical particles in a backward facing step. In this work, a Phase Doppler Particle Analyzer (PDA) was used to measure gas and particle phase velocities in a backward facing step. The step produced a 2:1 increase in cross sectional area with a Reynolds number of 22,000 (based on step height) upstream of the step. Spherical particles of 1 – 10 μm with an average diameter of 4μm were used to measure the gas phase velocity. At least three sizes in the range of (38 – 212 μm) for four different particles shapes were studied. The shapes included: spheres, flakes, gravel, and cylinders. Since the PDPA is not able to measure the size of the non-spherical particles, the particles were first separated into size bins and a technique was developed using the PMT (photo multiplier tubes) gain to isolate the particle size of interest for each size measured. The same technique was also used to measure terminal velocities of the particles in quiescent air. The measured gas phase velocity and spherical solid phase particles were in good agreement with previous measurements in the literature. The results showed relative velocities between the particles and gas phase to be in the range of 0 – 3 m/s which is in transition between stokes flow and fully developed turbulent flow. Drag coefficients were an order magnitude higher for non-spherical particles in turbulent flows in comparison to stokes flow which agreed reasonably well with quiescent terminal velocity drag. This information is valuable for modeling turbulent two-phase flows since most assumptions of the drag are currently based on correlations from empirical data with particles moving through a still fluid.

Micro particle image velocimetry (microPIV) is a non-intrusive tool for visualizing flow in micron-scale conduits. Using this investigative instrument, two experimental studies were performed to understand flow behaviors in microfluidic channels - a sudden expansion step flow and laminar velocity profile variation in diffusion driven mixing. First, flow in a backward facing step feature (1:5 expansion ratio) in a microchannel was taken as the subject of microPIV flow visualization. The onset and development of a recirculation flow was studied as a function of flow rate. This flow pattern was further used to investigate two major parameters affecting microPIV measurements; the depth-of-focus and recording time-intervals between images in a microPIV image pair. The onset of recirculation was initiated at flow rates that correspond to Reynolds numbers, Re > 95, which is well beyond the typical working range of microfluidic devices (Re=0.01-10). The recirculation flow has a 3D structure due to the dimensions of the microchannel and the effect of no slip condition on the walls. Ensemble cross-correlation was found not to be sensitive to variations of depth-of-focus and the output flow fields were similar as long as the overall optical focus remained within the upper and lower bounds of the microchannel. However, variations of time intervals between images in a microPIV pair, resulted in quantitatively and qualitatively different flow patterns for a given constant flow rate and depth-of-focus. In the second experiment, the effect of the laminar velocity profile and its variation on mixing phenomena at the reduced scale is studied. It is shown that the diffusive mass flux between two miscible streams, flowing in a laminar regime in a microchannel, is enhanced if the velocity at their diffusion interface is increased. Based on this idea, an in-plane passive micromixing concept is proposed and implemented in a working device (sigma micromixer). This mixer shows considerable mixing performance by periodically varying the flow velocity profile, such that the maximum of the profile coincides with the transversely progressing diffusion fronts repeatedly throughout the mixing channel. microPIV has been used to visualize the behavior of laminar flow inside the micromixer device and to confirm the periodic variation of the velocity profile through the mixing channel.

Helicopter operations in the vicinity of small naval surface vessels often require excessive pilot workload. Because of the unsteady flow field and large mean velocity gradients, the envelope for flight operations is limited. This experimental investigation uses a 1:144 scale model of the U.S. Navy destroyer DDG-81 to explore the problem. Both active and passive flow control techniques were used to improve the flow field in the helicopter's final decent onto the flight deck. Wind tunnel data was collected at a set of grid points over the ship's flight deck using a single component hotwire. Results show that the use of porous surfaces decreases the unsteadiness of the flow field. Further improvements are found by injecting air through these porous surfaces, causing a reduction in unsteadiness in the landing region of 6.6% at 0 degrees wind-over-deck (WOD) and 8.3% at 20 degrees WOD. Other passive configurations tested include fences placed around the hangar deck edges which move the unsteady shear layer away from the flight deck. Although these devices cause an increase in unsteadiness downstream of the edge of the fence when compared to the baseline, the reticulated foam fence caused an overall decrease in unsteadiness in the landing region of 12.1% at 20 degrees WOD. / Master of Science

This study looked at the impact of Ignatian spirituality and Ignatian pedagogy on staff in student-facing units at Jesuit colleges and universities. It also explored how leaders of student-facing departments and divisions operationalize components of Ignatian spirituality and pedagogy to create an Ignatian organizational culture. Qualitative data were collected through multiple semistructured interviews with nine leaders of student-facing units at Jesuit colleges and universities in the United States. Key findings were organized into four thematic sections. The findings map onto different components that derive from, or are connected to, Ignatian spirituality and pedagogy. The thematic sections are: (a) leadership’s commitment to human excellence; (b) subsidiarity; (c) showing the way to God through the spiritual exercises and discernment; (d) cura personalis and a commitment to well-educated solidarity off and on campus. These findings create a framework for leaders and student-facing staff to consult for engaging more meaningfully with Ignatian values in their attempts to build strong and positive organizational cultures for their units. Recommendations for addressing obstacles and opportunities are provided for staff leaders of student-facing units throughout the Jesuit network in the United States.

The retail sector is experiencing transforming changes driven by service robots (SR). While SR promise benefits such as improved inventory management, increased efficiency, and enhanced customer satisfaction, their integration presents technical and societal challenges. Technical hurdles encompass image classification under varying conditions, data security, localization, and obstacle detection. On the societal front, concerns revolve around public perception, safety, and employee apprehension regarding job security. This paper provides a comprehensive overview of these challenges and opportunities, highlighting that while SR have considerable potential, their optimal utilization in retail may be best suited for non-human facing tasks, given the current limitations of AI in human interactions.
