Metamorphs: Origin of the name

Back in 1996 I was getting bored, that was only getting to do structural drafting whilst had interests and capabilities, and qualifications beyond that. I was also opposed to the continuous improvement movement which seemed to be missing the perspective that a business needs to be dynamic and adaptive to respond to the dynamic environment in which it operated. An environment which is transformed by the very presence and action of the business enterprise. A world of chaos and uncertainty. Fluid as the imagination, like swirling paint mixing colours, the opening sequences to both Dr Who and the original The Tomorrow People. Not static: dynamic and moving, evolving. That utopia is static, and unsustainable, and is no where, and if somewhere, it is no where I want to be, and want to have no part in creating. Utopia if it is to be somewhere has to be dynamic: a dynamic utopia {something I started to write about in 1986}. A dynamic utopia is adaptive and evolving: and is built upon appropriate technologies best adapted to the environment in which it has to exist. Dynamic utopia can provide the basis of building habitat in space, and marching across the universe: to boldly go ... That the journey is more important than the destination. If the Sun has something like 6 billion years left (the number seems to vary), then have 2 billion years to find a new planetary home,  2 billion years to return and say, hey we found it, and 2 billion years to return. Just one little problem, if can survive travelling through space for 2 billion years, who needs a planet. {This thought came to mind watching the original Battle Star Galactica. Did they really need to get to their destination, and what then?} It is the exploration, the journey that has value, that is life.

So with this swirling chaos in my mind I wrote down a multitude of names that I dreamed up, one of which was Zhymekt {serious holistic industrial and mechanical technology}. Thus the names involved changes to letters of the alphabet, but main objective was to get reference to industrial and mechanical, to consider appropriate and adaptive technology, with implication of fluid imagination and Morpheus shaper of dreams. With a pocket book full of possible names, I went to the business names registry office to check the availability and register "Adaptive Technology", my preferred choice. At that point in time could only check the names at the registration office and that required a trip to the city {Now can check names on line, and nationally}. Already procrastinated long enough, so it was going to be a day of action, check availability and get it registered. Adaptive Technology, was already taken and so were many variants, and so Metamorphs was checked and became the instant replacement and was registered: for a business or rather enterprise that was going to pursue research and develop parametric generic models of adaptive technologies, and some other idealistic hyperbole.

Metamorphs produces, but it doesn't really trade. I make my living (?) through my fathers business Roy Harrison and Associates, which in 2009/2010 we went to register on the national companies register and found the name was taken, and so came up with MiScion Pty Ltd {which can be interpreted as: me off shoot (1.Scion 2.Scion). Except that the word "me", is pronounced with with the letter "i" having the sound as in the word "pit".}. Locally we still have registration of Roy Harrison and Associates as a business name, just not suitable for national usage.

So Metamorphs is where I pursue everything beyond structures: and doesn't have anything to do with MiScion Pty Ltd or Roy Harrison and Associates: though all the structural software I create and we use in the business has the name Metamorphs on it.

Any case the following are the two original descriptions for the name:


Version 1:

Meta : Transcending above and beyond
Morph : Form and structure

=> Transcending above and beyond structure

--------------------------------------------------------------------------------

Implications:
•The meanings of words are unclear and imprecise.
•The definition of an object can either be fixed and refer to a clearly defined instance of that object.
•Or the definition can be unclear and refer to multiple variations of a generic form.
•Some people have open minds and can see the generic nature of objects, others cannot
•
•Services not restricted to Structural Engineering Drafting & Design
•Structure is an abstract concept and can apply to objects other than buildings
•From an Industrial Engineering viewpoint Organisation structure is not fixed and can be changed
•
•Analytical Computer models are dependent initially on structured view of an object. But these models should be parametric, flexible,adaptable, and amorphous.
•The Language of Object Oriented Programming (OOP) provides the terminology for discussing an object oriented universe.
•Defining a specific instance of an object, or a generic object that is a description of a collection of like objects, is a never ending task of refinement.
•Language itself is dynamic, and the meanings of words change with time
•Objects do not have to be physical material things. They can be abstract ideas.
•
•Laws of thermodynamics suggest that mass and energy can neither be created nor destroyed just transformed from one form to another.
•The Gaia hypothesis suggests multiple levels of organisation structure and the emergence of higher forms of life. Cells congregate into multicellular lifeforms. These multi-cellular lifeforms congregate into societies, villages, cities, states, nations.
•The Gaia hypothesis suggests that there is a two way interaction between life form and environment. The mere presence of a Life form in an environment changes the environment. The life form needs to be continuously adapting to the constantly changing environment

Most of the form and structure that we perceive in the universe does not exist in reality, and is imposed by our own imaginations. If it does exist then it is transient, and exists for a short time frame. Even our perceptions and understanding change with time. So that patterns that were perfectly clear and obvious yesterday become a complete mystery to us today.

Metamorphs seeks out abstract generic definitions of objects. With such generic definitions perceptions of need can be transformed, undergo metamorphosis, and give birth to radically new objects.

--------------------------------------------------------------------------------

 Change one thing and you change everything ! 

Version 2:

Transcending above and beyond Structures.

Just as carbon, under extremes of temperature and pressure, deep within the earth can be transformed into diamond, and caterpillars emerge from their cocoons as butterflies. So too, it is possible, for engineers to transform the dust of the earth into valuable live sustaining resources. To an Engineer the Physical World is as Fluid as the Imagination.

Metamorphs seeks out abstract generic definitions of objects. With such generic definitions perceptions of need can be transformed, undergo metamorphosis, and give birth to radically new objects.

A bicycle becomes a rickshaw, becomes electrified railway, becomes telegraph, becomes internet. The need for transportation is transformed and displaced by the need for communication.

Confucius stated that "learning starts with the precise meaning of words". However the ancient Greek metaphysics philosopher Cratylus  considered that change was so complete and total that he believed that the meanings of words change the very instant that you uttered them.

The word Broadcast is an example of a word where our common perceptions of its meaning has changed with time. In the 1880's the common frame of reference was farming, and it meant to scatter seed widely with the hand. Today the frame of reference is information cast broadly by electronic mass media in the form of radio and television, and now the internet.

The meanings of words change through analogy and metaphor. With time the origin of the meaning becomes lost, and the metaphor reflects the common understanding of a word.

What is this ? If you say pencil, then you know its name, what we call it, but not what it is.

It is : The existential brain cell of a Cray supercomputer. An instrument for communication through visual symbols. A graphite based electrical resistor. A craft tool for sculpting clay. It is raw material.

What it is, is determined by the environment in which it is found. The needs, imagination's , and adaptive capabilities of those who find it available as raw material.


Once a product, whether it be a goods or service, hits the market place, the public arena, its purpose and function changes. The original design specification and intent become obsolete. And a need arises to redesign the product to match its actual usage, but once released, the process repeats itself, in a never ending cycle.

My spreadsheets DAO and 64 bit Windows 7

In process of reluctantly moving over to Windows 7, found a problem with my spreadsheets. Didn't want to change operating systems, but faulty power adapter connection forced me to get a new computer, that was about 18 months ago. Thus far the 64 bit Windows 7 computer been a good dust collector, as little installs on it, and it is otherwise slower than a wet weekend. What's with the spinning cursor, just execute the command already, instead of unnecessarily animating stuff: supposed to be a general purpose personal computing device not video game. Software developers seem to have lost the plot about what a personal computer is, and difference with a micro-computer and the importance of stable infrastructure. Not to put too fine a point on it but a virus is an annoying irritating piece of software which interrupts the users use of their computer: eg. Microsoft updates are a virus. All computer seems to have done for past 18 months is download updates: switch on to move software licenses, cannot do anything because updates need installing, runs out of battery power needs recharging, go do something else. Get more spare time, repeat same process, during which process seems to have got infected or otherwise messed up. Internet explorer dead, camera not functioning, and cannot install software for. Seems like may have to wipe clean and re-install from scratch. And there's all this rubbish about XP being defunct: its working perfect. Any way write more about operating systems and personal computers later.

Since I don't have 64 bit office, not even current for that matter (why would it need to be, I customize my own stuff), it seems that the Microsoft DAO 3.6 object library gets placed elsewhere. Normally it would be:

C:\Program Files\Common Files\microsoft shared\DAO\dao360.dll

On 64 bits using 32 bit software its likely to be:

C:\Program Files (x86)\Common Files\microsoft shared\DAO\dao360.dll

So to use my technical library will need to manually change the reference in the vba editor under tools references.

When first started with computers I avoided Microsoft products and stuck with Borland (Turbo Pascal, Turbo C, Quattro Pro, Paradox). I cannot go back down that path, but considering the free software options which are available on both Windows and Linux platforms. Start with them on Windows get used to them, and then move over to Linux. Zorin OS may be something worth looking at. There are a lot of problems to move over to Linux, from major applications (AutoCAD, Multiframe) to small utilities (xyplorer, beyond compare). But back in the early 1990's most high end graphical engineering software required a unix workstation: and likely a specific workstation like a Sun sparc. The problem being drivers for graphics, mice, and printers. At DOS every software developer needed to write drivers for their own application, and similarly with unix/Sun OS locked  to specific or limited range of hardware. MS Windows eliminated part of the problem, if the computer could run Windows then chances are could run specialist software.

The problem we have now though is not about supplying to meet needs, but changing stuff to acquire future income. Need and demand been satisfied, so what can be done to generate income tomorrow. I know, lets knock all the bridges down, along with the power stations and water filtration and pumping stations. Got a new fangled super material and I reckon it would be unsafe, a major national security risk, to keep all these things made out off that rubbishy concrete stuff. Whilst we're at it lets rip up those copper wires and optical fibre rubbish: you know the ones that connect the internet. And those tarmac, asphalt and concrete pavements they're ugly so lets get rid off them to: I'm sure we can think of something to replace them with, might but half defective and inferior. Wheels yeah, lets re-invent them, triangular ones they'd look good: wouldn't work, but who cares its change, and shouldn't resist change. There is just so much garbage on the internet about upgrading, and resistance to change. You do not destroy the heritage, the infrastructure the foundations on which everything is built.

Windows 8 apparently would be faster than Windows 7, and possibly fix the speed issue I have, but its likely more incompatible with the software I want to run. All I needed was new hardware. Software is expensive and bought progressively over the years: but having got, its not so easy to put aside and replace progressively.

On the other hand I did have a personal policy that engineering stuff I'm supposed to be able to do with pencil and paper, we should develop software in-house for and not depend on commercial software. So CAD or graphical editor is really only obstacle to moving to different operating system: most anything else just requires a compiler or spreadsheet.

However, there is no point to changing operating systems or application software if it is automatically updating on a regular basis. Once installed I expect the software to remain unchanged unless I find a problem with it. As for the internet and security, it is not necessary to be connected to the internet all the time, or have every device connected to the Internet.

We still operate DOS boxes because some software no longer available, or if new Windows version is available there is no benefit which would justify the expense, and otherwise doesn't function at Windows command prompt. I don't believe that kind of updating should have occurred, after all MS DOS ran from a 720 kbytye 3.5" floppy disk, so it should have been possible to fully accommodate in the 1 o 2 Gbyte bloat of the current Windows operating systems. From memory Sun OS had a full MS DOS installation which opened in a separate process window.

So it shouldn't be a problem to have an operating system which spawns different operating environments in isolated containers visually indicated  by windows. I think exists already and its called Unix.

Wind Loading Surface Roughness Length versus Terrain Category

A simple spreadsheet making use of AS1170.2:1989 Appendix E. This appendix provided formula for converting surface roughness length (z0) into terrain category and for region A the calculation of the terrain adjusted wind speed or otherwise the terrain category multiplier (Mz,cat).

AS1170.2 commentary contains a design chart which identifies various terrains and gives the surface roughness length (z0). From this chart it is apparent that most rural properties are not TC3 but also they are not TC2. By the use of z0 an intermediate terrain category can be calculated and more economical designs are possible.

The spreadsheet can be downloaded here: surfaceRoughnessLength.xls

Wind Loading Risk Assessment

A simple spreadsheet which allows varying life expectancy and calculates the mean return period (R) for the regional wind speed. It is based on formula in Wind Loading of Structures by John Holmes.

It also attempts to map the calculated mean return period to the nearest building code of Australia (BCA) importance level, and return the associated mean return period for such. This part is limited to non-cyclonic regions: A and B.

Wind Loading BCA Importance Levels

A simple spreadsheet that maps Building Code of Australia (BCA) importance levels against the annual probabilities of exceedance (actually mean return periods). Excel trend line facilities are then used to get a formula so that any mean return period can be mapped to an importance level.

Whilst AS1170.2 allows for any mean return period, the BCA has limitations, which are not always suitable, starting with the fact that the BCA is primarily about habitable buildings and anything which is not a habitable building becomes BCA class 10. However the BCA is not suitable for design of any structure classified as class 10. For example a garden shed or carport may be suitable to be designed to BCA volume 2, but a 600m high radio mast is not.

Additionally importance level 2, with mean return period (R) of 500 years is not suitable for all buildings, and then again an importance level of 1 (R=100 years) is not always suitable, therefore helpful to identify alternative importance levels: to show that have importance between 1 and 2.  For those who prefer importance levels.

The spreadsheet can be downloaded here. bcaImportanceLevels.xls

Revised Links to downloads

The links to applications and MS Excel workbooks which were stored on the personal web space which came with my Internet access account have now been replaced with links using Dropbox. So the downloads should be available again.

In search of South Australian Building Industry Web Presence

The following is a list of various suppliers to and in the South Australian building industry. It is not a recommendation, it is just a search for suppliers I am familiar with and an investigation to what web presence they have, whether it is a web site, presence on social networks, or simply a listing in the white pages and or yellow pages telephone directories. Some of these businesses we have done design/engineering work for in the past, or otherwise specify their products, others simply have a presence in the market place which cannot be ignored.
