GENTLE CABBAGE HARVESTING

Super-Flexible Nanogenerator for Energy Harvesting from Gentle Wind and as an Active Deformation Sensor

Using an Al-foil of thickness ≈ 18 μ m as a substrate and electrode, a piezoelectric nanogenerator (NG) that is super-fl exible in responding to the wavy motion of a very light wind is fabricated using ZnO nanowire arrays. The NG is used to harvest the energy from a waving fl ag, demonstrating its high fl exibility and excellent conformability to be integrated into fabric. The NG is applied to ...

A gentle introduction to

The PythonTEX package allows authors to combine computational and typesetting tasks by embedding Python code in TEX documents. This package allows access to many powerful Python modules, providing support for such things as symbolic mathematics, plotting, arbitrary precision numerical calculations, and networking. Python’s intuitive syntax, popularity, and extensibility along with TEX’s formatt...

Cryptographic Voting - A Gentle Introduction

These lecture notes survey some of the main ideas and techniques used in cryptographic voting systems. The write-up is geared towards readers with little knowledge of cryptography and it focuses on the broad principles that guide the design and analysis of cryptographic systems, especially the need for properly designed security models. We use a system proposed by Fujioka, Okamoto and Ohta as s...

Expectation Maximization: a Gentle Introduction

This tutorial was basically written for students/researchers who want to get into first touch with the Expectation Maximization (EM) Algorithm. The main motivation for writing this tutorial was the fact that I did not find any text that fitted my needs. I started with the great book “Artificial Intelligence: A modern Approach”of Russel and Norvig [6], which provides lots of intuition, but I was...
