## Wireless Telegraphy Regulations 1924

The commencement of the Wireless Telegraphy Regulations 1924 reflected the transition of regulation of wireless from the Department of Navy to the Postmaster-General's Department and enabled a new era of amateur activity which had effectively been quashed since early in the first World War.

# History of wireless telegraphy and broadcasting in Australia/Topical/Biographies/Edward Gustavus Campbell Barton
### Edward Gustavus Campbell Barton

Edward Gustavus Campbell Barton was a prominent electrical engineer based in Brisbane, Queensland. He placed Brisbane and much of Queensland at the forefront of public use of electricity, especially in respect of street lighting. He was a founding member of the pre-WW1 Wireless Institute of Queensland and the post WW1 Queensland Wireless Institute. His wireless experiments in the late 1890s and early 1900s pre-dated the monopoly of the Commonwealth Postmaster-General's Department and the issuing of callsigns, but were conducted from Brisbane, Queensland, primarily in the context of popular lectures for the Brisbane Central Technical College. Despite his involvement with early amateur radio clubs he does not appear to have been active as a wireless operator post 1910, perhaps more to his powerful oratory and organisational skills. A summary biography has not yet been prepared however the following resources have been assembled in preparation:
* Transcriptions and Notes - Edward Gustavus Campbell Barton - More than 70 transcriptions and notes

# History of wireless telegraphy and broadcasting in Australia/Topical/Biographies/Ernest Kilburn Scott
### Ernest Kilburn Scott

In 1904 P. N. Russell left a £100,000 bequest to the University of Sydney for the establishment of the electrical engineering department. A prominent English researcher and engineer, Ernest Kilburn Scott was brought to Australia to head the department and place it on a sound footing.
As well as his University work, Scott became a popular commentator on matters of topical engineering importance, including wireless telegraphy. Famously entered into a war of words in 1905 through letters to the editor, with John William Ormsby Hamilton, then Australian representative for the International Telegraph Construction Co who was promoting the Shoemaker System of wireless telegraphy for a scheme to link Australia, New Zealand and the Pacific Islands.
Evidence of Scott experimenting in wireless telegraphy in Sydney has not yet been identified, but given his extended experience and knowledge of the Marconi system in England, such experiments are almost certain.
Scott returned to England in 1910, but kept in touch with his former colleagues and students, a number of the latter completing their education in England as a result.
A comprehensive biography of Ernest Kilburn Scott has not yet been prepared, however the following resources have been assembled in preparation:
* Transcriptions and Notes - Ernest Kilburn Scott - More than 10 transcriptions and notes
* Photos, QSL cards and other graphics - Ernest Kilburn Scott - Nothing uploaded as yet

# History of wireless telegraphy and broadcasting in Australia/Topical/Biographies/Ernest Richard Cooling
### Ernest Richard Cooling

Ernest Richard Cooling was a prominent amateur operator, amateur broadcaster and amateur club participant from the early 1920s to the early 1930s. His station callsign was 4BN (4=Queensland, B=?, N=?) and he operated from Toowoomba, Queensland. He was appointed honorary radio inspector for Toowoomba (no doubt due to his employment in the PMGD) during the brief period before the PMGD Wireless Branch assumed all such responsibilities. He was employed by the PMGD throughout his working life, rising slowly through the ranks from letter carrier, telegraphist and postal assistant. His service was mostly Toowoomba-based, but he was transferred for brief periods to Bowen, Barcaldine and Clifton. Despite his relatively young age, after a number of years of poor health, both mentally and physically, he became depressed and took his own life in tragic circumstances. A summary biography has not yet been prepared however the following resources have been assembled in preparation:
* Transcriptions and Notes - Ernest Richard Cooling - More than 90 transcriptions and notes

# History of video games/AR
## Prototype Technology of the 1980's and 1990's

During the Cold War there was a massive amount of Research and Development ongoing by both government and commercial agencies, which had a side effect of trickling down to consumers later, namely in Augmented Reality, and general advances in computing. During this time, a number of marketing attempts to promote the technology would be made. Though this technology would not see consumer use in the 1980's and 1990's, it would form the basis for common gaming technologies decades later.
HUD development greatly influenced AR development

## Augmented Reality is fielded

The mid 2010's saw large corporations begin to push into the field with their own entries in Augmented Reality. Google Glass and Microsoft Hololens help popularize the idea augmented reality devices in the public, though neither device sees widespread consumer use.

# Infrastructure as Code - vSphere, Packer, and Terraform

This book is a collection of efforts used to build Infrastructure as Code in vSphere.
When I started down this journey there was a lot of information on AWS, GCP and the like, but vSphere was few and far between.
Over the course of a year many different resources were found and they helped create environments whereby the power of vSphere API and IaC platforms worked together.

Among the devops community there are multiple discussions about using count + index functions instead of loops. While count does work I lean toward for_each loops.
# Introduction to Communication Theory/Semiotics

The literary theorist Kenneth Burke famously described human beings as "the symbol-making, symbol-using, symbol-misusing animal". Our broad use of symbols is a contrast from every species on earth. Only our closest relative, the Bonobo has shown any semblance of our symbol-using ability. It is the unique act of creating meaning out of arbitrary signs (be they vocalizations, gestures, or pictographs) that allows us to communicate an infinite range of concepts so fluently.
Through the Looking Glass, Chapter 6, by Lewis Carroll: "When I use a word," Humpty Dumpty said, in rather a scornful tone, "it means just what I choose it to mean -- neither more nor less." "The question is," said Alice, "whether you can make words mean so many different things." "The question is," said Humpty Dumpty, "which is to be master -- that's all."
Put in other words, put forth by different authors, "naming is the fundamental symbolic act".

# LMIs in Control/Stability of Lure's Systems
## The System

    ${\begin{aligned}{\dot {x}}(t)&=Ax(t)+B_{p}p(t)+B_{w}w(t),\\z(t)&=C_{z}x(t)\\p_{i}(t)&=\phi _{i}(q_{i}(t)),i=1,\dots ,n_{p}\\q&=C_{q}x,\\0&\leq \sigma \phi _{i}(\sigma )\leq \sigma ^{2}\ \forall \sigma \in \mathbb {R} \end{aligned}}$

## The Data

The matrices $A,B_{p},B_{w},C_{q},C_{z}$.

## The LMI: The Lure's System's Stability

The following feasibility problem should be solved as sufficient condition for the stability of the above Lur'e system.
       ${\begin{aligned}{\text{Find}}\;&P>0,\Lambda =diag(\lambda _{1},\dots ,\lambda _{n_{p}})\succeq 0,T=diag(\tau _{1},\dots ,\tau _{n_{p}})\succeq 0:\\&{\begin{bmatrix}A^{\top }P+PA&PB_{p}+A^{\top }C_{q}^{\top }\Lambda +C_{q}^{\top }T\\B_{p}^{\top }P+\Lambda C_{q}A+TC_{q}&\Lambda C_{q}B_{p}+B_{p}^{\top }C_{q}^{\top }\Lambda -2T\end{bmatrix}}\prec 0\\\end{aligned}}$

## Implementation

https://codeocean.com/capsule/0232754/tree

## Conclusion

If the feasibility problem with LMI constraints has solution, then the Lure's system is stable.

## Remark

The LMI is only a sufficient condition for the existence of a Lur’e Lyapunov function that proves stability of Lur'e system . It is also necessary when there is only one nonlinearity, i.e., when $n_{p}=1$.

# LMIs in Control/Template

This methods uses LMI techniques iteratively to obtain the result.

## The System

Given a state-space representation of a system $G(s)$ and an initial estimate of reduced order model ${\hat {G}}(s)$.
    ${\begin{aligned}\ G(s)&=C(sI-A)B+D,\\\ {\hat {G}}(s)&={\hat {C}}(sI-{\hat {A}}){\hat {B}}+{\hat {D}},\\\end{aligned}}$
Where $A\in \mathbb {R} ^{n\times n},B\in \mathbb {R} ^{n\times m},C\in \mathbb {R} ^{p\times n},D\in \mathbb {R} ^{p\times m},{\hat {A}}\in \mathbb {R} ^{k\times k},{\hat {B}}\in \mathbb {R} ^{k\times m},{\hat {C}}\in \mathbb {R} ^{p\times k}$ and ${\hat {D}}\in \mathbb {R} ^{p\times m}$.

## The Data

The full order state matrices $A,B,C,D$.

## The Optimization Problem

The objective of the optimization is to reduce the $H_{\infty }$ norm .

## The LMI: The Lyapunov Inequality

Objective: $\min \gamma$.
Subject to:: ${\begin{aligned}\ P&={\begin{bmatrix}\ P11&P12\\\ P21&P22\\\end{bmatrix}}\ >0,\end{aligned}}$
${\begin{aligned}{\begin{bmatrix}\ A^{T}P11+P11A&A^{T}P12+P12{\hat {A}}&P11B-P12{\hat {B}}&C^{T}\\\ {\hat {A}}^{T}P12^{T}+P12^{T}A&{\hat {A}}^{T}P22+P22{\hat {A}}&P12^{T}B-P22{\hat {B}}&{\hat {C}}^{T}\\\ B^{T}P11-{\hat {B}}^{T}P12^{T}&B^{T}P12-{\hat {B}}^{T}P22&-\gamma {I}&D^{T}-{\hat {D}}^{T}\\\ C&{\hat {C}}&D-{\hat {D}}&-\gamma {I}\\\end{bmatrix}}\ >0\end{aligned}}$

## Conclusion:

The LMI techniques results in model reduction close to the theoretical bounds.
