Jozef Stefan Institute 3 articles published in JoVE Engineering Deep Neural Networks for Image-Based Dietary Assessment Simon Mezgec1, Barbara Koroušić Seljak2 1Jožef Stefan International Postgraduate School, 2Computer Systems Department, Jožef Stefan Institute The goal of the work presented in this article is to develop technology for automated recognition of food and beverage items from images taken by mobile devices. The technology comprises of two different approaches - the first one performs food image recognition while the second one performs food image segmentation. Engineering Hybrid Printing for the Fabrication of Smart Sensors Lisa-Marie Faller1, Johanna Zikulnig2, Matic Krivec2, Ali Roshanghias2, Anze Abram3, Hubert Zangl1 1Institute for Intelligent Systems Technologies, Alpen-Adria-Universität Klagenfurt, 2Carinthian Tech Research AG, 3Department for Nanostructured Materials, Jozef Stefan Institute Here we present a protocol for the fabrication of inkjet-printed multilayer sensor structures on additively manufactured substrates and foil. Chemistry A Simple Method for the Size Controlled Synthesis of Stable Oligomeric Clusters of Gold Nanoparticles under Ambient Conditions Marlon Lawrence1, Anze Testen1, Tilen Koklic2, Oliver Smithies1 1Department of Pathology and Laboratory Medicine, University of North Carolina at Chapel Hill, 2Condensed Matter Physics Department, Laboratory of Biophysics, Jozef Stefan Institute We describe a simple method for producing highly stable oligomeric clusters of gold nanoparticles via the reduction of chloroauric acid (HAuCl4) with sodium thiocyanate (NaSCN). The oligoclusters have a narrow size distribution and can be produced with a wide range of sizes and surface coats.
