Informedia at TRECVID 2003: Analyzing and searching broadcast news video

We submitted a number of semantic classifiers, most of which were merely trained on keyframes. We also experimented with runs of classifiers were trained exclusively on text data and relative time within the video, while a few were trained using all available multiple modalities. 1.2 Interactive search This year, we submitted two runs using different versions of the Informedia systems. In one run, a version identical to last year's interactive system was used by five researchers, who split up the topics between themselves. The system interface emphasizes text queries, allowing search across ASR, closed captions and OCR text. The result set can then be manipulated through: • storyboards of images spanning across video story segments • emphasizing matching shots to a user’s query to reduce the image count to a manageable size • resolution and layout under user control • additional filtering provided through shot classifiers such as outdoors, and shots with people, etc. • display of filter count and distribution to guide their use in manipulating storyboard views. In the best-performing interactive run, for all topics a single researcher used an improved version of the system, which allowed more effective browsing and visualization of the results of text queries using

Coupling of CFD and semiempirical methods for designing three-phase condensate separator: case study and experimental validation

This study presents an approach to determine the dimensions of three-phase separators. First, we designed different vessel configurations based on the fluid properties of an Iranian gas condensate field. We then used a comprehensive computational fluid dynamic (CFD) method for analyzing the three-phase separation phenomena. For simulation purposes, the combined volume of fluid–discrete particle method (DPM) approach was used. The discrete random walk (DRW) model was used to include the effect of arbitrary particle movement due to variations caused by turbulence. In addition, the comparison of experimental and simulated results was generated using different turbulence models, i.e., standard k–ε, standard k–ω, and Reynolds stress model. The results of numerical calculations in terms of fluid profiles, separation performance and DPM particle behavior were used to choose the optimum vessel configuration. No difference between the dimensions of the optimum vessel and the existing separator was found. Also, simulation data were compared with experimental data pertaining to a similar existing separator. A reasonable agreement between the results of numerical calculation and experimental data was observed. These results showed that the used CFD model is well capable of investigating the performance of a three-phase separator

The TA Framework: Designing Real-time Teaching Augmentation for K-12 Classrooms

Recently, the HCI community has seen increased interest in the design of teaching augmentation (TA): tools that extend and complement teachers' pedagogical abilities during ongoing classroom activities. Examples of TA systems are emerging across multiple disciplines, taking various forms: e.g., ambient displays, wearables, or learning analytics dashboards. However, these diverse examples have not been analyzed together to derive more fundamental insights into the design of teaching augmentation. Addressing this opportunity, we broadly synthesize existing cases to propose the TA framework. Our framework specifies a rich design space in five dimensions, to support the design and analysis of teaching augmentation. We contextualize the framework using existing designs cases, to surface underlying design trade-offs: for example, balancing actionability of presented information with teachers' needs for professional autonomy, or balancing unobtrusiveness with informativeness in the design of TA systems. Applying the TA framework, we identify opportunities for future research and design.Comment: to be published in Proceedings of the 2020 CHI Conference on Human Factors in Computing Systems, 17 pages, 10 figure

The Effect of Early Ambulation of Patients on Bleeding and Hematom Via the Femoral Artery in Post Angiography Ward in Ayatollah Moosavy Hospital(Zanjan 2011)

Introduction: Coronary angiography is frequently applied for diagnostic purposes in patient with coronary artery disease. There is no consensus about the optimal time for the ambulation on patients following femoral arterial puncture. This study intended to investigate the differences between 6 hours of complete bed rest and 2 hours of complete bed rest for the patients after angiography. Methods: This clinical trial study was performed in 100 patients candidated for coronary angiography. The patients were randomly divided in to experimental and control groups. Primarily, demographic data was filled, and then intervention was done for two groups. The arterial sheath was immediately removed after the procedure. Hemostasis was achieved by manual compression and maintained with sandbags. Early ambulation was performed after two hours of supine bed rest following sheath removal. The incidence of bleeding and hematoma was documented in 24 hours after the procedure. Results: Our findings were indicative of no significant differences between the two groups in terms of gender, age, body mass index, catheter size, total procedure duration, total hemostasis time, history of anticoagulant drag use and coagulation tests before angiography. Conclusion: Ambulation of 2 hours after angiography via the femoral artery is as feasible and safe as that of 6 hours of bed rest. Therefore, an early ambulation protocol can shorten hospital stay without significant vascular complication

Avalanche! Reanimating Multiple Roles in Child Computer Interaction Design

Abstract. This paper values children as design partners in Child Computer Interaction to ensure building environments highly suitable for the target group. However, it appears beneficial to address underlying roles, align design processes on school activities or give considerations to the voluntary nature of such projects. We conducted eight projects with 75 pupils using initial learning environments. We found that starting design processes with pupils as users helps to identify further design steps that can be consequently tackled with the former users as informants and design partners. Thus, we suggest the Avalanche Design Cycle to engage children as fresh users at several stages asking them to become informants and design partners consecutively. The Avalanche Design Cycle is an iterative design process complying with school life allowing pupils to join/leave design teams. Thereby, it is aiming at sustained team sizes and more representative groups
