Performance improvement of automated melanoma diagnosis system by data augmentation

Color information is an important tool for diagnosing melanoma. In this study, we used a hyper-spectral imager (HSI), which can measure color information in detail, to develop an automated melanoma diagnosis system. In recent years, the effectiveness of deep learning has become more widely accepted in the field of image recognition. We therefore integrated the deep convolutional neural network wit

The Miracle of Wörgl

Recent attempts by several big tech companies to create their own currencies, such as Facebook's Libra, have drawn attention to monetary innovations. The case offers important insights for this debate by engaging with the wave of monetary innovation and entrepreneurship triggered by the unemployment and economic distress of the Great Depression in the 1930s. Through the vantage point of one of the

FairCoop : The global cooperative and its collaborative cryptocurrency

The case is about today's crypto-activists' efforts to organise a cooperative global economic system that is an alternative to the State and to market capitalism. Through the vantage point of FairCoop, the reader gets an insight on the necessary elements needed to consider when organizing an economic system for the commons: a community that produces, a market in which products can be exchanged, an

Málaga Común

The case is about the choice of governance structures for a community currency in the impoverished South of Spain that aims to alleviate the economic hardships brought by the economic crisis. The reader gets an insight into the economic contexts of these currencies, the functioning of one of its most common designs (mutual credit systems or LETS), as well as the governance structures of community

Below-surface water mediates the response of African forests to reduced rainfall

Terrestrial ecosystem gross primary productivity (GPP) is the largest land-atmosphere carbon flux and the primary mechanism of photosynthetic fixation of atmospheric CO2 into plant biomass. Anomalous rainfall events have been shown to have a great impact on the global carbon cycle. However, less is known about the impact of these events on GPP, especially in Africa, where in situ observations are
