Make love and war – Quantifying discrete male polymorphic reproductive ratios

A paper I never officially published

Make love and war – Quantifying discrete male polymorphic reproductive ratios

Abstract
Fighters primarily develop at low population densities; Though the
proportion of males becoming fighters at any given density may change over time. This change is likely to be due to condition-dependence. Data is presented to illuminate these matters and a model is developed linking fighter development to the costs of being a fighter (in terms of survival) and the benefits of being a fighter (in terms of fecundity).

Automatic Identification System Live 3D tracking

The Automatic Identification System is the focus of this article. I programmed the full stack to get my home AIS (Automatic Identification System) feed. Then I added  AISHUB’s AIS feed on a 2D and a 3D Map.

I show this on www.deepship.ai. 30000 to 34000 live ships are tracked usually in 1 minute intervals.

Pollution in Venice close to Cruise ships

Introduction

Old Venice has become famous for its pollution.
https://www.theguardian.com/environment/2017/jul/31/heading-to-venice-dont-forget-your-pollution-mask.

The claim is:

“As big ships sailed down the main canal, just a stone’s throw from the shore, my team recorded up to 500 ultra-fine particles per cubic centimetre – 500 times higher than clean sea air.”

DeepShip or ShipNet: Matlab Multiple Transfer Deep Learning Ship/Ferry Detection

Using Matlab and the Computer Vision System Toolbox, Image Processing Toolbox, Neural Network Toolbox, Parallel Computing Toolbox and the Statistics and Machine Learning Toolbox, I labelled 1923 images from my web cam feed with tags, [ferry], [ship], [bird] [meteor].
