This paper introduces novel ways of improving awareness and reflection through visualizations of badges as an abstraction of learning analytics data. We report initial findings with both a personal dashboard approach, Navi Badgeboard, that provides details on student and class progress, and a collaborative, interactive tabletop visualization, Navi Surface, to promote group reflection. We evalua...

A reflection map, induced by the deterministic Skorohod problem on the nonnegative orthant, is applied to a vector-valued function X on the nonnegative real line and then to a+X, where a is a nonnegative constant vector. A question that was posed over 15 years ago is, under what conditions does the difference between the two resulting regulated functions converge to zero for any choice of a as ...

Abstract: This paper proposes a novel scheme for multi-static passive radar processing, based on soft-input soft-output processing and Bayesian sparse estimation. In this scheme, each receiver estimates the probability of target presence based on its received signal and the prior information received from a central processor. The resulting posterior target probabilities are transmitted to the c...

Reflection and collaborative reflection are common activities at workplace, in which people alone or together with colleagues revisit experiences to learn for future situations. Often support needs arise during reflection and for example people get stuck and don’t know how to continue. We propose to fill this gap with prompting as tool-supported scaffolding mechanism. Based on literature and ou...

In this paper, we propose a new method for estimating reflection properties of a real object surface from a single specular component image, as well as the light source position. Polarization is used for separating the diffuse and specular reflection components. Different from previous approaches, which heavily assumed both distant viewpoint and illuminant position, our method can work even und...

On the basis of the continuity equation and the Bernoulli equation in the steady form, a differential equation is developed to evaluate the successive water levels within compartments of an upright perforated wave absorber. Then the initial and boundary conditions are introduced and the differential equation is solved as an initial value problem. Finally the reflection coefficient from the wave...

Smooth-pursuit adaptation (SPA) refers to the fact that pursuit gain in the early, still open-loop response phase of the pursuit eye movement can be adjusted based on experience. For instance, if the target moves initially at a constant velocity for ~100-200 ms and then steps to a higher velocity, subjects learn to up-regulate the pursuit gain associated with the initial target velocity (gain-i...

ARTICLE INFO ABSTRACT ARTICLE HISTORY: Received 27 October 2013 Revised 28 November2013 Accepted 4 December 2013 Recently, time reversal (TR) method, due to its high functionality in heterogeneous media has been widely employed in microwave imaging (MI) applications. One of the applications turning into a great interest is through-wall microwave imaging (TWMI). In this paper, TR method is appli...
