Impact of the high share of converter-interfaced generation on electromechanical oscillations in Continental Europe power system
2020
This study investigates the effects of converter-interfaced generation integration on the dynamic response of the power system of Continental Europe. The system is analysed with a large-scale dynamic model of the entire synchronous area, considering different instantaneous integration percentages of converter-interfaced generation across the system. The study focuses on the reduction of the overall available kinetic energy and the impact on frequency dynamics and system oscillations. The dynamic model of the system originally provided by ENTSO-E is further developed according to a specific methodology, replacing a determined amount of synchronous generation and introducing a corresponding a…
Inter-area oscillations in the 500-kV Vietnamese power system
2019
The paper presents the study of the 500-kV Vietnamese power system. The oscillatory response of the system is analyzed both with a modal analysis and a time domain analysis. The 500-kV system of Vietnam is modeled in details, including all the power plants with the corresponding regulators. The model is developed in collaboration with the Institute of Energy Science IES-VAST of Vietnam and it is validated with the data provided by the National Load Dispatch Centre (NLDC) of Vietnam. The simulation results reveal a clear identification of potential inter-area oscillations between North and South of the Country. A worsening of the observed phenomenon should be considered as possible, especial…

Multi-modal search for multiobjective optimization: an application to optimal smart grids management
2012
This paper studies the possibility to use efficient multimodal optimizers for multi-objective optimization. In this paper, the application area considered for such new approach is the optimal dispatch of energy sources in smart microgrids. The problem indeed shows a non uniform Pareto front and requires efficient optimal search methods. The idea is to exploit the potential of agents in population-based heuristics to improve diversity in the Pareto front, where solutions show the same rank and are thus equally weighted. Since Pareto dominance is at the basis of the theory of multi-objective optimization, most algorithms show the non dominance ranking as quality indicator, with some problem i…
Students with Severe, Permanent Disabilities and Their Educational Inclusion in Spain
2014
This article analyses the educational inclusion of students with severe and permanent disabilities in the different autonomous communities of the Spanish State. After describing the Spanish socio-economic context, a comparative analysis is carried out based on the following indicators: the conception of severe, permanent disabilities; the regulation framework; responsibility of schooling and provision of services; identification and assessment of flaws; incidence in the population; curricular proposals (model and modalities of support); specific centers and units; human and material resources; the role of families and funding. The analysis of the implemented policies concludes by pointing o…
Supporting Diagnosis and Treatment of Scoliosis: Using Augmented Reality to Calculate 3D Spine Models in Real-Time - ARScoliosis
2020
Scoliosis is a complex spinal disorder that mostly affects adolescents and younger population. To avoid and reduce harmful radiation techniques in adolescent idiopathic scoliosis investigation and follow-ups, a novel non-invasive approach is highly recommended and needed in clinical practice. In this paper ARScoliosis application to diagnose, visualize and document spinal condition and particularly adolescent idiopathic scoliosis in real time is presented. This ARScoliosis application is developed in Unity 3D, a game engine, and allows non-invasive quantification of posture and spinal deformity using recently available non-ionizing wide-angle depth sensor Microsoft Azure Kinect DK as a diag…
The Prevalence of Amblyopia in Germany
2015
Amblyopia is a condition in which reduced visual acuity is not directly caused by an organic defect (1). Amblyopia can develop when an infant or small child suffers from strabismus. Although both eyes are healthy, different images are formed on each fovea centralis (where vision is sharpest) and on other corresponding locations on the retina; this is in contrast to individuals without strabismus. To prevent double vision the child’s brain suppresses the image produced by one eye. Complete visual ability cannot develop in this eye during the sensitive phase of visual development (2). Approximately half of amblyopia cases (3) are caused by uncorrected higher refractive errors, which are frequ…

Modālie darbības vārdi un vārdkopas ekonomiskajos tekstos
2016
Valoda var tikt izmantota, lai ietekmētu un pārliecinātu cilvēkus, tādēļ ir nepieciešams izpētīt, ar kādiem līdzekļiem tas tiek darīts un kādu efektu šie līdzekļi atstāj uz lasītāju. Šis pētījums ir mērķēts uz modālo vārdu un vārdkopu analīzi 37 ekonomikas tekstos no The Economist, lai tālāk analizētu, kāda nozīme ir izteikta ar konkrēto modālu lietošanu. Diskursa un biežuma analīze tika pielietota, lai sasniegtu šo mērķi. Rezultāti rāda, ka raksti ir drīzāk informatīvi un aprakstoši, jo epistēmiskā nozīme ir pielietota visbiežāk. Dinamiskā nozīme ir lietota, lai izteiktu spējas vai dinamiskas iespējas. Deontiskā nozīme ir vērojama retāk, un izmantota, lai norādītu uz neizbēgamu vai vidēji …
