Calculus: Limits of Functions (Part 2 of x)

Preface
This series is aimed at providing tools for an electrical engineer to analyze data and solve problems in design. The focus is on applying calculus to equations or physical systems.

Introduction
This article will introduce limits.

There are many calculus references, the one I like to use is Calculus by Larson, Edwards and Hostetler.

This also assumes you are familiar with Python or can stumble your way through it.

Data Storage Solution: Backup & Cloud

Data Availability
Data is usually made available by two means: redundancy and reliability.

Effort has been made to buy reliable hardware. Top of the line SSD, motherboard, memory, CPU and power supplies are used in the server.

Data is made redundant by providing multiple on-line copies of data. This is achieved primarily through a RAID1 mirror and protects against bad sectors and disk failures.

At some point I should add a small UPS to protect against power outages and brown outs.

Data Storage Solution: Rationale

Introduction
Time to upgrade my ailing, 99% filled 350GB spinning disk mirror.

There were several end user requirements:

Data Storage Solution: Hardware & OS

Overview
This entry covers the technical details of the implementation.

I approached this by breaking down the stack into individual steps and then I conduct performance, security and data management reviews.

The Physical Stack

  • Storage Devices
  • Storage Controller
  • Server
  • Network
  • Site
  • User

Linear Algebra in Engineering: Summary (Part 7 of 7)

Preface
This series is aimed at providing tools for an electrical engineer to analyze data and solve problems in design. The focus is on applying linear algebra to systems of equations or large sets of matrix data.

Introduction
This article will attempt to organize the previous series of articles into a decision tree allowing you to quickly choose the best method for a particular problem.

Procedure
First, ask yourself some questions about your data and the type of answer you need.

Linear Algebra in Engineering: Analyzing Dynamic Systems with Markov Chains (Part 6 of 7)

Preface
This series is aimed at providing tools for an electrical engineer to analyze data and solve problems in design. The focus is on applying linear algebra to systems of equations or large sets of matrix data.

Introduction
This article will demonstrate the use of Markov Chains. This can be used to analyze models with cyclic or or repeated outcomes.
