Chalcopyrites are a material class widely used in thin film solar cell manufacturing, with the most prominent industrially applied example being CIGS (CuInGaSe2). In order to maximize the effectiveness of these solar cells and minimize the cost, the search for appropriate alternative materials is still ongoing. In this work, we show that the lattice parameters of chalcopyrite are linearly dependent …
Operating Systems: The Key To A New World
IT is probably the fastest growing sector in the world. With new technologies being continuously developed, it seems we’ll just keep going forward. There is an issue, however. Since the birth of the internet we have been building up high on the foundations of IT, operating systems. They have become less talked about, and fewer and fewer people are actually …
Dynamic Proactive Secret Sharing for Confidential Byzantine Fault-Tolerant Services using Multi-party Computation
New methods for blockchain technology and decentralized infrastructures emerged using Byzantine Fault-Tolerant (BFT) State Machine Replication (SMR), a reliable approach for creating trustworthy services. However, BFT SMR lacks secrecy protection, though it ensures integrity and availability even in the presence of live adversaries. Earlier attempts to address this issue integrated secret sharing into the consensus-based framework of BFT SMR but …
NutriBean+
Grain legumes have been of great interest to the European community as they show favourable nutritional and environmental traits. These crops, thus, are key to the Farm to Fork Strategy. The Sobrero and Marconi High Schools, with the assistance of the University of Turin, have characterised four varieties of chickpeas and four of soybeans, focusing mainly on the evaluation of …
Research of the quality of water and sediments in the Silistra region of the Danube
The Danube River, spanning 19 countries, faces pollution risks from various sources. Its importance extends beyond fishing, serving as recreation and sustenance. Despite the seriousness of pollution, community awareness is lacking. Monitoring efforts near Silistra focus on water quality, ignoring sediment evaluation. Analysis revealed high cadmium levels. Lack of Bulgarian sediment standards led to reliance on American and European data. …
Parkinson Detector: Artificial Intelligence for medical diagnosis
Parkinson Detector is an inexpensive and non-invasive system for early diagnosis of Parkinson’s disease. By using an artificial intelligence algorithm, it is capable of detecting oscillation parameters of the upper limbs and calculating specific indexes useful for diagnosis. The system uses hardware consisting of a PC and two high-definition cameras. Through specially developed software, it recognizes the person’s movements and …
Automatic Ski Edge Tuner
The aim of this project is to develop an innovation in the field of ski preparation. For this purpose, a device has been designed as well as built which can simultaneously grind both ski edges in a single work step. Furthermore, the prototype can operate independently of the power grid, allowing it to be used independent of the location and …
Hidden Agenda: TFA – The invisible danger in our water
The aim of our project is to survey trifluoracetate (TFA) concentrations in surface waters in the Vienna Basin for the first time in Austria and to investigate the impact of TFA on plants. Thus, it should be shown that secondary pollutants also have an environmental relevance and should be included in monitoring programmes due to their accumulation in the environment. …
Using network centrality measures as predictors of gene drive deployment outcomes
Gene drives are genetic constructs with super-Mendelian inheritance that can spread engineered alleles in wild populations to suppress disease vectors and invasive species, with deployment programs to begin within a decade. We developed a network-based model of gene drive spread with an arbitrary number of populations connected by gene flow. Using generative network models, we identified network centrality measures of …
Sign language translator glove
As you may know, a lot of people around the world are deaf or mute, almost all of them speak sign language and our project is to help them in the best way possible without any restriction. To achieve that, we made a glove that gives us values when you bend a finger and when you move the hand. For …
