Unexpected geological structures can cause safety and economic risks during underground excavation. Therefore, predicting possible geological threats while drilling a tunnel is important for operational safety and for preventing expensive standstills. Subsurface information for tunneling is provided by exploratory wells and by surface...

In this study, experiments are performed towards the identification and measurement of unsteady modes occurring in a transitional swept wing boundary layer. These modes are generated by the interaction between the primary stationary and travelling cross-flow instabilities or by secondary instability mechanisms of the stationary cross-flow...

The success of future fusion power plants as a sustainable energy source greatly depends on their uptime. This uptime relies on the plant's maintenance, which must be performed via tele-manipulation. Tele-manipulated maintenance is challenging, as exemplified by strictly selected and highly trained operators who still require more time to work...

The cohesive element has been widely employed to model delamination and matrix cracking in composite materials. However, an extremely fine mesh along the potential crack path is required to achieve accurate predictions of stresses within the cohesive zone. A sufficient number of cohesive elements must be present within the cohesive zone ahead...

Streamflow and sediment loads undergo remarkable changes in worldwide rivers in response to climatic changes and human interferences. Understanding their variability and the causes is of vital importance regarding river management. With respect to the Changjiang River (CJR), one of the largest river systems on earth, we provide a...

This thesis describes the theory, design, and implementation of chopper operational amplifiers (op-amps) in CMOS integrated circuits (ICs). The chopping technique periodically corrects DC errors of such op-amps, so that low 1/f noise and stable, microvolt-level offset can be achieved. However, chopping causes switching artifacts at the amplifier...

Ballast track is the most widely used track for the railway transport, and ballast bed plays a significant role to provide resistances during train operation. Generally, the ballast bed consists of crushed stones. To achieve the mitigation of ballast degradation, the first priority is to describe the degradation development and to study its...

In this paper, we explore the challenges towards the adoption/use of Open Educational Resources (OER) within the Greek Higher Education (HE). To achieve this objective, first we present “Kallipos”, a large-scale open access textbook publishing initiative that was launched in 2013 by the Hellenic Academic Libraries Link (HEAL-Link) consortium....

A common claim in open education is that librarians are effective supporters in open education work because their talents for research, organization, and working with students make them natural supporters of faculty designing OER courses. This study seeks to understand how librarians and faculty interacted with one another in an deliberate...

This papers focuses on the use of learning dashboards in higher education to foster self-regulated learning and open education. Students in higher education have to evolve to independent and lifelong learners. Actionable feedback during learning that evokes critical self-reflection, helps to set learning goals, and strengthens self-regulation...

Programming is considered as an essential skill in the 21st century. Visual programming languages and age-appropriate development environments allow an easy entry into this field. Nevertheless, it is very challenging to bring those skills in a very short time frame to schools, to their teachers, and to school children themselves. Therefore, Graz...

MOOCs provided by Higher Education Institutions (HEIs) have the potential to open up education to a wider audience. By implementing appropriate quality assurance measures, they could also provide a first creditable step into the formal higher education system. Exploring the potential of credentialization and recognition of MOOCs was a major...
