When you got a statistical data and you need to describe your data in a mathematical function, you need then to fit a distribution with your data. In general four steps in fitting distributions:
- Choose a function that you think fits the more with your data
- Estimate parameters
- Evaluate the quality of the fit
- Do statistical test
This article, in general, is not aimed to give information how to fit a distribution with a specific language, although you can do that very easily using R, or Python. Read More
As a student at Oklahoma University in Electrica and Computer Engineering, I took a course of Linear Analysis. The course material was available online from Stanford. Honestly, it was one of the best courses, very helpful and enjoyable. In this post, I’m gonna write about my experience and what I’ve learned from this course. (Note this post will be updated by adding more details later on).
In this course we took a look at the linear dynamical systems, it starts with a general overview on linear algebra including basis, dimension, null space of a matrix, range of a matrix, rank of a matrix, conservation of dimension, orthogonal and orthonormal set of vectors, QR factorization.

Recently, I was working on a project to find the position of a target point (e.g. mobile phone), in an indoor environment. Many technologies are being used in this area including WIFI, Bluetooth, RFID and all kind of sensors you can imagine on your mobile phone.
In this article, I will explain my experiment in detecting position based on Bluetooth beacons, I used three estimote beacons, with a Raspberry pi 3 to be as the target point that I want to detect its position.
In mathematics, a Voronoi diagram is a partitioning of a plane into regions based on distance to points in a specific subset of the plane. That set of points (called seeds, sites, or generators) is specified beforehand, and for each seed there is a corresponding region consisting of all points closer to that seed than to any other. These regions are called Voronoi cells. The Voronoi diagram of a set of points is dual to its Delaunay triangulation.
The origin of Voronoi diagram dates back to the 17th century. R. Descartes claims in his book  that the solar system consists of vortices. This concept has independently emerged, and proven useful, in various fields of science.
