That article provides step-by-step calculations to assess a standard PV installation power output at a theoretical level. The steps are the following:

  1. Light intensity at sun’s surface

In a last section, previous calculations are illustrated through a practical example.

1. Light intensity at sun’s surface

Assuming that the sun can be approximated the Sun as a black body, the intensity (W/m²) of thermal electromagnetic radiations that it emits only depends on temperature and is given by Stefan-Boltzmann law:

When it comes to invest in cryptocurrencies, one can get a bit lost.

Blockchain and investing are both complex topics. To make your way through this jungle and eventually get out as a successful investor, I believe it’s important to follow best practices and use efficient tools.

In a short series of articles, I share what I’ve learned about blockchain and cryptocurrency, combining experts’ insights and my personal field experience.

In this article, you will find:

  1. Investing best practices to minimize risks and make rational decisions.

Over the last decades, the money we use to make transactions, namely fiat currencies, has been mostly dematerialized. Bank notes have gradually turned obsolete while most of our cash assets have been migrated on digital accounts, usually hosted by bank servers. Under that centralized system, the bank has full control over your data and funds and is in charge of ensuring your account’s security.

Until 2009, for those who didn’t want to put their money in the hands of someone else, the only alternative was to stick with bank notes — which was still highly risky and not very convenient…


Techno-economical analysis to assess the potential of anaerobic digesters in UK dairy farms

This project was conducted over my year at Imperial College London, as part of the MSc Sustainable Energy Futures.

The objective was to address the problem of the UK’s dairy farming sector decarbonization via identifying a sustainable solution and assessing its economical feasibility.

This article provides a short summary of the work performed, articulated around three sections:

  1. Understanding two main challenges faced by dairy farms: (1) greenhouse gas emissions and (2) electricity costs.

Identifying handwritten digits by training MLP and CNN on the famous MNIST dataset.

MNIST dataset— Source: Kaggle

This project is part of the online course Machine Learning, Data Science and Deep Learning by Sundog Education.

The objective is to develop a classification algorithm that can identify handwritten digits with the highest accuracy possible.

The data used for this project comes from the MNIST dataset which is a very good basis for people who want to try learning techniques and pattern recognition method on real-world data.

The project has been developed using Python and the code is available in open-source on my GitHub.

Methodology 🗺️

For this project, the classification problem is tackled via Supervised Deep Learning.

The objective is to develop a classification algorithm that can predict whether a mammograph mass is benign or malignant with the highest accuracy possible.

The project has been developed using Python and the code is available in open-source on my GitHub.

Methodology 🗺️

For this project, the classification problem is tackled via Supervised Learning. Training data has been collected from the “mammographic masses” public dataset from the UCI repository.

First of all, a data pre-processing step will be performed to explore the dataset, handle…


Introduction à la nouvelle version de la seconde Blockchain la plus populaire.

Début Novembre, Ethereum a enfin annoncé le lancement de sa tant attendue version 2.0 ! Cet article s’intéresse à ce qu’est cette nouvelle version et les évolutions majeures qu’elle entraîne.

Mais avant de se plonger dans le vif du sujet, quelques rappels sur ce qu’est Ethereum.

Rappels sur Ethereum 1.0 🌐

Depuis son lancement en 2015, Ethereum est rapidement devenu la blockchain la plus utilisée après Bitcoin.

Cela fait maintenant plusieurs années que son token, l’ether (ETH), représente la seconde plus grosse capitalisation du marché crypto — à l’heure actuelle, on parle d’environ 52 milliards de dollars ce qui représente une part de marché de…
