# Guide to X11/Window Managers/ion3

ion3 is/was a tiling WM that would primarily be operated with the keyboard, but also allowed for basic operations, like switching and dragging windows as well as resizing frames, using a mouse.
The windows are tiled in frames, with their titles in tabs above the actual content, so multiple windows could be inside one frame, but only one remains visible with its tab highlighted accordingly. Clicking the mouse on a tab is an alternative way of switching the active window. Secondary mouse button on the tab would bring up a menu with basic window operations.
It's configuration files are written in lua code, thus enabling rather dynamic setups.
ion3 also has a very basic floating window mode that could optionally be chosen when creating new workspaces (virtual desktops). Windows can not be iconified, but at least rolled up.
A minor flaw in ion3 is not being able to use the mouse to bring up a root menu for launching applications. So it could be operated with the mouse to some degree, but relies on the keyboard or at least some sort of launcher to start applications. Switching workspaces is also not possible without the use of a keyboard or a workaround that would translate mouse events to keys.

# A-level Mathematics/MEI/C3/Differentiation

Differentiation in Core 3 (C3) are an extension of the work that you did in Core 1 and Core 2.

# Differentiation
## Standard Derivatives

For the C3 module, there are a few standard results for differentiation that need to be learnt. These are:
${\frac {d}{dx}}\ln x={\frac {1}{x}}$
${\frac {d}{dx}}e^{kx}=ke^{kx}$
${\frac {d}{dx}}\sin kx=k\cos kx$
${\frac {d}{dx}}\cos kx=-k\sin kx$
${\frac {d}{dx}}\tan kx={\frac {k}{cos^{2}{kx}}}$

## Chain Rule

${\frac {dy}{dx}}={\frac {dy}{du}}{\frac {du}{dx}}$
The Chain Rule is used to differentiate when one function is applied to another function. A typical example of this is:
$y=\sin(x^{2})$
One of the ways of remembering the chain rule is: Find the derivative outside, then multiply it by the derivative inside. In the example above, this becomes:
${\frac {dy}{dx}}=2x\cos(x^{2})$

## Product Rule

${\frac {d}{dx}}uv=v{\frac {du}{dx}}+u{\frac {dv}{dx}}$
The product rule is used when two functions are multiplied together.

## Quotient Rule

${\frac {d}{dx}}{\frac {u}{v}}={\cfrac {v{\cfrac {du}{dx}}-u{\cfrac {dv}{dx}}}{v^{2}}}$
The quotient rule is used when one function is divided by another. It is a specific case of the product rule. A typical example of this is:

## Implicit Differentiation

Implicit differentiation is used when a function is not a simple $y=something$ but contains a mixture of x and y parts. A typical example of this is to differentiate:
$y^{2}+2y=4x^{3}$
When differentiating the y components of the expression you differentiate as normal, and then multiply by ${\frac {dy}{dx}}$. So differentiating both sides of the above expression it becomes:
$2y{\frac {dy}{dx}}+2{\frac {dy}{dx}}=12x^{2}$
Then by factorising the left hand side and cancelling, this becomes:
${\frac {dy}{dx}}={\frac {6x^{2}}{y+1}}$
# A-level Mathematics/MEI/C2/Radians

There are 3 ways to measure angles, the most common way up until now has been to use degrees. As we all know there are 360$^O$ degrees in a circle. however this number was picked arbitrarily long ago and has no real value.
Note: This is why the gradian was invente (to decimalise angles), however you do not need to know anything about gradians.
In core 2 you are introduced to radians, they will be used on and off for the remainder of the A-level maths course. There are 2π radians in a circle. Although this might seem another arbitrary decision it is not. It is the angle at which the radius is equal to arc length. This means that Radians are actually a number.
# A-level Mathematics/MEI/C1

This is the first pure module of the MEI A-level Mathematics book. Knowledge of intermediate tier GCSE is assumed. The Exam is an hour and a half long, and is a non-calculator paper. It can be taken in June.

* Co-ordinate Geometry
* Polynomials
# A-level Mathematics/MEI/C1/Polynomials
### Polynomials

polynomials are equations of the type ax$^n$ + bx$^{(n-1)}$ + ... + c. In Core 1 you would be expected to be able to sketch and solve them. you only need to worry about positive powers of x for C1.

## Sketching

To sketch a function you need to know:
* Crossing points with both axis
* whether the graph is above or below the axis between crossing points.
* the general shape of the graph.
As we can see by looking to the right graphs of an even power are a "U" shaped curve. with greater powers having a longer "flat" section between 1 and -1
A graph has a limited number of turning points. This is 1 less than the highest power.
An equation with an odd power follows the same rule but will have a curvy shape starting at the bottom going through zero and then going off the top of the screen. I recommend that you use a graphing program like Geogebra to visualise these graphs.
Remember if the highest power has a coefficient of -1 then the curve will be upside down.

## Solving

TBC - soon hopefully.

# Electric Motors And Generators/Single-phase

Electric Motors And Generators

## Single Phase Alternating Current
### From a wire in a magnetic field to the Mains/line power source

Basically an electric voltage is generated in a wire if either that wire is in a changing magnetic field, or if the wire is moved into or out of a magnetic field. Single phase Alternating voltage (and Alternating Current if there is something connected to that wire or coil) is produced when a magnet, or magnet equivalent, is rotated inside a coil of wire. The more turns of wire there are in that coil, the higher the voltage, and the faster the rotation, the higher the frequency. If a graph would be drawn showing the relation of the voltage at the terminals of the coil with time, then that graph would be of sinusoidal shape, alternating between positive (+V$_e$) and negative (−V$_e$) in a complete rotation. If the coil would be rotated at a speed of 3000 revolutions per minute, then there would be 3000/60=50 cycles per second (= 50 Hz), the unit's name being Hertz (Hz), and if the coil would be rotated at 3600 revolutions per minute then the voltage would change at a frequency of 60 Hz. The usual AC (mains or line) frequency is 50 or 60 Hz, depending on the country concerned.
The electrical power available in North American homes is single phase 60 Hertz 120 volts. AC current's advantage over DC current is the efficient transmission over long distances using step-up and step-down transformers.
* Note that 3-phase transformers are, in fact, 3 single-phase transformers whose voltages are 120 degrees displaced from the other two, and that any terminal of a 3-phase transformer versus the neutral terminal (shown as N below) has a single phase voltage. A building's load could, for example, be divided into three separate single-phase loads, more or less equal to one another; these loads would be supplied from a three-phase transformer, all three voltages being versus the neutral terminal; that terminal is usually connected to ground/earth.
120 volts is the root mean square ($V_{rms}$) of the maximum voltage ($V_{max}$) .
$V_{rms}={\frac {V_{max}}{\sqrt {2}}}$
$V_{max}=V_{rms}\cdot {\sqrt {2}}$
$V_{max}=120\ volts\cdot 1.414=170\ volts$

- Transmission systems
Three Phase Alternating Current
Three Phase Alternating Current
Distribution:
In North America, three phase alternating current is generated and transmitted using three conductors to industry, commercial buildings and to a group of houses. Some older installations use 2400/4160Y three-phase systems, but most currently use 7200/12470Y. Near a group of houses is a step down transformer wired in a "Wye" or "Star" configuration. Each individual house receives one of these three phases. The neutral conductor comes from the middle tap of the "Wye." Other houses receive different phases which are balanced throughout the group. One 7200 volt line feeds a transformer to a house, which then creates two hot legs and one neutral 120/240.
Load (end use) in consumer applications:
In a house, the breaker panel provides connections between the two phases and the neutral conductor. Most of the household outlets are connected between one of the "hot" phases and the neutral with a safety breaker permitting a maximum of 15 amperes. For the larger loads, such as the oven and the clothes dryer, the breaker panel connects across the two hot phases to provide 240 volts, limited to a maximum of 40 amperes.

# Electric Vehicle Conversion/Concrete vehicles

Note the presence of hazardous materials and conditions that must be approached with proper precautions and procedures to avoid damaging, injurious, or even fatal consequences.

## Toyota Prius

It is relatively easy to turn a Prius into a well-performing pure EV.
One would start with a 2004+ Prius with a worn-out or destroyed engine, but intact transaxle. Remove the engine and gear the transaxle's engine input shaft to the output shaft, possibly with a cogbelt. This is to turn the engine input shaft at a speed (e.g. 500 rpm @ 60 miles per hour or 97 km/h) that prevents MG1 from overspeeding when driving at highway speeds (above 62 miles per hour or 100 km/h ) while making MG1's output power available to help drive and stop the vehicle.
With MG2 rated at 50 kW output and MG1 rated at at least 25 kW, one could potentially provide up to 75 kW to the wheels for acceleration as an EV, only slightly less than the 82 kW peak available as a hybrid. One could remove the 21 kW DC:DC converter between the battery and motors, and instead provide a battery pack with a peak charging voltage of 500V. The motors and high power drive electronics could be used as is. It would hopefully be possible to bypass all the hybrid system logic and use only the motor driver circuits; otherwise, they would have to be replaced.
Electrovaya makes a 48V Li-ion module that stores 1.6 kWh and weighs 9.5 kg (21 lb). A 1P9S/2P9S/3P9S, 433V, pack would hold 11.4/23.0/34.6 kWh to 80% DOD and weigh 188/376/564 lb. One of these packs would add just -112/76/264 lb to the vehicle after removal of an estimated 300 lb of OEM battery, engine, and related components—and would provide an estimated 57/115/170 miles of EV range. The battery cost, however, would be US$17k/$35k/$52k at an estimated $1200 per kWh-capacity.
A 1P33S pack of 12V, 30Ah Gold Peak NiMH modules would add 324 lb to the vehicle's weight, store 9.5 kWh to 80% DOD and weight 624 lb. It would add 324 lb and would provide an estimated 48 miles of EV range. At an estimated $1200 per kWh-capacity, the pack would cost $14.3k
In contrast, fuel savings at $0.10/kWh vs. $4.50/gallon would be $0.075/mile or only $11k over 150,000 miles at today's prices, well below the cost of even the 48 EV mile battery pack.

### Genset trailer and external PHEV

For long trips and extended range, one can put the Prius´ internal combustion engine and fuel tank in a genset trailer, becoming an external plug-in hybrid electric vehicle.

<pagequality level="3" user="Zoeannl" />style="background: #ececec; text-align: left; padding-left: 0.5em; font-weight: bold;" class="table-rh"of free trade comes to triumph, one brief enactment will constitute our whole economic code. In the first case, the law will proclaim that all exchanges with foreign countries are prohibited; in the second, that all exchanges with foreign countries are free; and many grand and distinguished personages will thereby lose their importance.
But if exchange does not possess a character which is peculiar to it,—if it is not governed by any natural law,—if, capriciously, it be sometimes useful and sometimes detrimental,—if it does not find its motive force in the good which it accomplishes, its limit in the good which it ceases to accomplish,—if its consequences cannot be estimated by those who effect exchanges;—in a word, if there be no absolute principles, then we must proceed to weigh, balance, and regulate transactions, we must equalize the conditions of labour, and try to find out the average rate of profits— colossal task, well deserving the large emoluments and powerful influence awarded to those who undertake it.
On entering Paris, which I had come to visit, I said to myself. Here are a million of human beings, who would all die in a short time if provisions of every kind ceased to flow towards this great metropolis. Imagination is baffled when it tries to appreciate the vast multiplicity of commodities which must enter to-morrow through the barriers in order to preserve the inhabitants from falling a prey to the convulsions of famine, rebellion, and pillage. And yet all sleep at this moment, and their peaceful slumbers are not disturbed for a single instant by the prospect of such a frightful catastrophe. On the other hand, eighty departments have been labouring to-day, without concert, without any mutual understanding, for the provisioning of Paris. How does each succeeding day bring what is wanted, nothing more, nothing less, to so gigantic a market? What, then, is the ingenious and secret power which governs the astonishing regularity of movements so complicated, a regularity in which everybody has implicit faith, although happiness and life itself are at stake? That power is an absolute principle, the principle of freedom in transactions. We have faith in that inward light which Providence has placed in the heart of all men, and to which He has confided the preservation
and indefinite amelioration of our species, namely, a regard to

Among the arguments which we hear adduced in favour of the restrictive régime, we must not forget that which is founded on national independence.
"What should we do in case of war," it is said, "if we are placed at the mercy of England for iron and coal?"
English monopolists do not fail to cry out in their turn:
"What would become of Great Britain, in case of war, if she is dependent on France for provisions?"
One thing is overlooked, which is this—that the kind of dependence which results from exchange, from commercial transactions, is a reciprocal dependence. We cannot be dependent on the foreigner without the foreigner being dependent on us. Now, this is the very essence of society. To break up natural relations is not to place ourselves in a state of independence, but in a state of isolation.
Remark this: A nation isolates itself looking forward to the possibility of war; but is not this very act of isolating itself the beginning of war? It renders war more easy, less burdensome, and, it may be, less unpopular. Let countries be permanent markets for each other's produce; let their reciprocal relations be such that they cannot be broken without inflicting on each other the double suffering of privation and a glut of commodities; and they will no longer stand in need of naval armaments, which ruin them, and overgrown armies, which crush them; the peace of the world will not then be compromised by the caprice of a Thiers or of a Palmerston; and war will disappear for want of what supports it, for want of resources, inducements, pretexts, and popular sympathy.
I am quite aware that I shall be reproached (it is the fashion of the day) with basing the fraternity of nations on men's personal interest—vile, prosaic self-interest. Better far, it may be thought, that it should have had its basis in charity, in love, even in a little self-abnegation, and that, interfering somewhat with men's material comforts, it should have had the merit of a generous sacrifice.
When shall we be done with these puerile declamations? When will tartuferie be finally banished from science? When shall we cease to exhibit this nauseous contradiction between our professions and practice? We hoot at and execrate personal interest; in other words, we denounce what is useful and good (for to say that all men are interested in anything is to
say that the thing is good in itself), as if personal interest were
