In today’s world, higher education, especially in technical sciences, is crucial when speaking about a change in values and attitudes towards sustainability. Engaging students in learning and training process as well as developing their research skills and creative capacity is challenging. This study inquiries into the current academic activities and role of used educational technologies and methodologies for encouraging active learning in both undergraduate and postgraduate programs when teaching any engineering course in general, and geospatial sciences in particular. The result of the study suggests the importance of interdisciplinary project and problem-based learning, building partnership with universities, students and industrial companies, monitoring, developing, and implementation of new educational technologies. © 2014, © 2014 Wuhan University.

The capability of generating terajets using three-dimensional (3D) dielectric cuboids working at terahertz (THZ) frequencies (as analogues of nanojets in the infrared band) is introduced and studied numerically. The focusing performance of the terajets is evaluated in terms of the transversal full width at half maximum (FWHM) along x- and y-directions using different refractive indices for a 3D dielectric cuboid with a fixed geometry, obtaining a quasi-symmetric terajet with a subwavelength resolution of ∼0. 46λ0 when the refractive index is n = 1.41. Moreover, the backscattering enhancement produced when metal particles are introduced in the terajet region is demonstrated for a 3D dielectric cuboid and compared with its two-dimensional (2D) counterpart. The results of the jet generated for the 3D case are experimentally validated at sub-THZ waves, demonstrating the ability to produce terajets using 3D cuboids. © 2014 AIP Publishing LLC. Source

An approach aimed at providing compatibility and complementarity of real time kinematic (RTK) and precise point positioning (PPP), the well-known methods for high-precision positioning of mobile objects, using low-cost GLONASS/GPS equipment is proposed. Introduction of advanced modifications of these methods does not involve any changes in the existing ground infrastructure. © 2015, Pleiades Publishing, Ltd. Source

In the past, it has been demonstrated that it is possible to produce terajets with high resolution at its focus using 3D dielectric cuboids under plane-wave illumination. Here, a systematic study of the harmonic and angular response of terajets using cuboids is performed. Mutifrequency focusing is demonstrated at the fundamental frequency and two higher frequency harmonics showing an intensity enhancement of ∼10, ∼18, and ∼14 for each case. This capability to use 3D dielectric cuboids to produce terajets at the fundamental frequency and first harmonic is experimentally evaluated at sub-THz frequencies, with good agreement with numerical results. Moreover, a robust angular response is demonstrated numerically and experimentally showing that the intensity at the focal position is maintained in a wide angular range (from 0° to 45°), demonstrating the capability to work as a wide scanning terajet-focusing lens. The results here presented may be scaled at different frequency bands such as optical frequencies and may be used in microscopy techniques and sensors. © 2015 Optical Society of America. Source
