Unlike synchronous generators, wind turbines cannot directly respond to large disturbances, which may cause transient instability, due to their power electronic-based interface and maximum power control strategy. To effectively monitor the influence of wind turbines, this paper proposes an approach that combines decision trees (DTs), and a...

In this article, we highlight the pressing need for integrating the windows of opportunities that digital transformation of education opens up with circular economy education to accelerate the achievements of sustainability outcomes. Circular economy transition, as a multi-scalar process, relates to several contexts, e.g., product, firm,...

Location of wind power plants and demand centres are not always close by; hence, the transmission of energy puts a burden on existing grid infrastructure. This unwanted burden necessitates transmission lines to operate more and more frequently close to their operating limits. To alleviate such situations, this research addresses the advantages...

This paper develops efficient channel estimation techniques for millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) systems under practical hardware limitations, including an arbitrary array geometry and a hybrid hardware structure. Taking on an angle-based approach, this work adopts a generalized array manifold separation...

The ubiquity of large virtual worlds and their growing complexity in computer graphics require efficient representations. This means that we need smart solutions for the underlying storage of these complex environments, but also for their visualization. How the virtual world is best stored and how it is subsequently shown to the user in an...

It has been 10 years since the first MOOC was prepared by George Siemens and Stephen Downes on connectivism and connected knowledge at the University of Manitoba. From 25 participants only to hundreds of thousands of students in 2011, MOOCs became a hype in technology-enhanced learning context. Nevertheless, the phenomenon of MOOCs has become...

We present a scalable solution to render complex scenes from a large amount of viewpoints. While previous approaches rely either on a scene or a view hierarchy to process multiple elements together, we make full use of both, enabling sublinear performance in terms of views and scene complexity. By concurrently traversing the hierarchies, we...

Providing online design education offers a unique opportunity for learning, by providing high quality learning experiences to distributed audiences for free. It has its challenges as well, particularly when the aim is use ‘active learning’ strategies (Biggs & Tang, 2011), which are necessary when teaching design. In this paper, we report...

In the present study, we refer to Carr's theory on the nature of educational practice for evaluating teaching as a praxis in relation to two major changes, i.e. ubiquitous learning and massive communication caused by MOOCs. With regard to the first change, we argue that the teacher is faced with the problem of encouraging the learners to get...

Massive Open Online Courses (MOOCs) require students’ motivation either intrinsically or extrinsically to complete any of its courses. Even though MOOCs enjoy great popularity and bring many benefits to the educational community, some concerns arise with MOOC advancement. In fact, MOOCs are affected by low completion rate and face issues with...

Kinetics of the austenite (γ) to ferrite (α) transformation and the reverse ferrite (α) to austenite (γ) transformation in a series of Fe-X (X = Ni, Mn and Co) binary alloys has been experimentally and theoretically investigated. A transition from partitioning to partitionless transformation has been predicted to occur during both the γ→α and...

Point cloud data are an important source for 3D geoinformation. Modern day 3D data acquisition and processing techniques such as airborne laser scanning and multi-beam echosounding generate billions of 3D points for simply an area of few square kilometers. With the size of the point clouds exceeding the billion mark for even a small area,...

The effect of heating rate on the formation and decomposition of austenite was investigated on cold-rolled low carbon steel. Experiments were performed at two heating rates, 150 ˚C/s and 1500 ˚C/s, respectively. The microstructures were characterized by means of scanning electron microscopy (SEM) and electron backscattered diffraction (EBSD)....

This dissertation addresses the challenges of wireless local area networks (WLANs) that operate in the unlicensed sub-1GHz industrial, scientific, and medical (ISM) band. Frequencies in the 900MHz spectrum enable a wider coverage due to the longer propagation characteristics of the radio waves. To utilize globally available sub-1GHz (S1G) ISM...

MAPPER Lithography is developing a maskless lithography technology. The technology combines massively-parallel electron-beam writing with high speed optical data transport used in the telecommunication industry. The electron optics generates 13,000 electron beams that are focused on the wafer by electrostatic lens arrays which are manufactured...
