Detection of moving objects concealed behind a concrete wall corner has been demonstrated, using Doppler-based techniques with stepped-frequency radar centered at 10 GHz, in reduced-scale model street scenario. Micro-Doppler signatures have traced the return from human target, both for walking and breathing. Separate material measurements reflection transmission showed that reflections are dominating wave propagation mechanism producing target detections, while components transmitted through...
Abstract We aim to challenge assumptions made about the use of English as a “lingua franca” in scientific-academic contexts, identify impact such on trajectories knowledge production and uptake, legitimize multiple languages for transnational scholarly exchange. set out ten principles: Using does not always promote inclusion; A language positioned can act domination; Positioning policy may discourage translations exclude participation; Policies which position being contemporary convey idea...
This study compares students' experiences of two types criteria-based assessment: in-text commentary and rubric-articulated feedback, in an assessment design combining the feedback channels. The main aim is to use responses shed light on how strategies for formative can be optimised. Following action research methodology, discusses key categories student from three sources: reflective texts, a questionnaire, interviews. Results show that different functions were attributed channels:...
Using an experimental coherent high-resolution X-band radar, we show that micro-Doppler signatures from one or more walking persons can be retrieved off the radar line of sight in a realistic urban environment. The off-sightline objects are illuminated by wave multipath wall reflections. Velocity-time diagrams created for specific targets using short-time Fourier transform. Two scenarios studied, with and two persons, respectively, along closed path.
Background: Research suggests that communication instruction is particularly effective when situated in disciplinary courses. While studies show this approach improves skills, less known about how it enhances engineering learning. Literature review: Prior work includes approaches to integrating into engineering, of writing learn, and explorations the role identity development. question: How might integration practice undergraduate courses support learning? Methodology: Because little...
In a globally networked learning environment (GNLE), 16 students at university in Sweden and 17 the United States exchanged peer-review comments on drafts of assignments they prepared English for their technical communication classes. The instructors both sets had assigned same projects taught courses way that previous year, which contrasts with common practice having partnering work assignment or linked created specifically GNLE. authors coded students’ 816 according to focus orientation...
The possibility of detecting moving people around the corner using multipath propagation radar waves has previous been demonstrated in experimental set-ups. Here, we present measurements from a realistic scene system operating at X-band stepped-frequency mode. objects include person(s), bicycle, and car(s). A semi-monostatic single receiver-transmitter was used as data collector. All detections were made by Doppler filter processing. We can identify target returns after one two wall...
Detection of moving objects around corners, with no direct line-of-sight to the objects, is demonstrated in experiments using a coherent test-range radar. A setting was built up on ground consisting two perpendicular wall sections forming corner, an opposite wall, intended mimic street scenario reduced scale. Two different materials were used, viz. light concrete and metallic walls. The latter choice served as reference, elimination transmission through walls, e.g. facilitating comparison...
A recent study of new software developers at Microsoft reveals the significance and integration communication skills in their daily tasks. While literature offers a variety approaches to promote into Computer Science curriculum, discrepancy remains between what students get they need. In this paper, we propose using workplace scenarios that integrate with technical content situated mediating activity. Workplace are based on an analysis as activity system. Guidelines for implementing...
Analysts such as Hanushek and Woessman have brought to the fore deceptiveness of education enrolments, or years schooling, in growth regressions need consider educational quality. In this paper, a nonlinear programming solution is proposed way normalising single scale country average test scores from various international testing programmes. This method, though less transparent more dependent on certain subjective choices than existing approach put forward by Woessman, allows for inclusion...
In this paper we present an algorithm for location of stationary objects behind corners using X-band radar. A street-like scenario is considered. The relies on the estimation a reference signal calculated with Geometrical Optics and diffraction theory. By multipath propagation, show by means simulations that it possible to locate
Abstract The promotion of high-quality written communication in the disciplines is an important learning outcome higher education. Given time invested by students and teachers alike, it crucial that writing assignments also promote engagement content learning. But worth for university to invest such ‘writing-to-learn’ activityes? We find can be, present improved design experimental lab-report assignment English medium instruction environment, where additional language. Our context...
Approaches to teaching writing engineers vary widely across institutions, from standalone courses housed in English departments fully integrated writing-in-the-disciplines programs, as well a range of models between that represent partnerships and technical faculty. But little is known about how each approach used, who responsible for instruction, or what the overall goals are. In this exploratory study, we present an initial meta-analysis map current approaches engineering instruction by...
In this letter, we present a new methodology for measuring the bistatic ground scattering coefficient σ <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sup> at large angles and in near field of rough surface. To filter out unwanted radar returns, out-gating from inverse synthetic aperture (ISAR) imaging is performed area interest. Comparisons are made with near-field compensated advanced integral equation method model.
University technology transfer can be described as an organizational activity that transfers research results in the form of innovations or other knowledge utilized for benefit society.Most commonly, it is accomplished through licensing intellectual property to commercial actors are able utilize practical applications (1).This a rather well-established process concrete technologies, but more broad, such those concerning and social change, face challenges undergoing same process.Simply put,...
