Situating Programming Abstractions in a Constructionist Video Game

open access: yesInformatics in Education, 2014
Research on the effectiveness of introductory programming environments often relies on post-test measures and attitudinal surveys to support its claims; but such instruments lack the ability to identify any explanatory mechanisms that can account for the

Efficient Data Collection in Widely Distributed Wireless Sensor Networks with Time Window and Precedence Constraints

open access: yesSensors, 2017
In addition to the traditional densely deployed cases, widely distributed wireless sensor networks (WDWSNs) have begun to emerge. In these networks, sensors are far away from each other and have no network connections.

Computational models in cardiology [PDF]

open access: yesNature Reviews Cardiology, 2018
The treatment of individual patients in cardiology practice increasingly relies on advanced imaging, genetic screening and devices. As the amount of imaging and other diagnostic data increases, paralleled by the greater capacity to personalize treatment, the difficulty of using the full array of measurements of a patient to determine an optimal ...

Integrated compact duplexer for Tx/Rx SatCom on the move user terminals

open access: yesScientific Reports
This paper presents the design and characterisation of a package-integrated duplexer for K/Ka-band Satcom-on-the-move user terminals. The proposed duplexer features a highly compact design, integrated within a package stackup, and utilises two bandpass ...
