Ray Avery

Went to MIT guys for advice on making incubator. They suggested a car part model. That seemed useless because repair would be very hard to do since each part would be custom made and very hard to service in a third world country.

The ideal would be to make something that did not require any repairing, at all.
  • Incubator - costs nothing and requires no replacement.
  • Snap fitting - no screw driver likely to be found in third world countries.
  • Making things indestructible - physically and electronically.
  • "Life Raft"
  • Eventual incubator can be sold in third world countries but also first world. "It is not a cheap knock off".
The baby generates the bugs (source). The air needs to be cleaned from within. Using UV LEDs to kill the bugs. LEDs also serves as an impromptu heating element. Air filters can be made self cleaning through periodic reversal of air flow into the incubator.

A refined sensor-ability: Applying process algebra to sensor network analysis

Allan McInnes

Communicating Sequential Processes (CSP): mutually consistent denotationally; operationally; and algebraic semantics.

Refinement can provide verification.

Node modeling. Example node:
  • TinyOS: programmed in nesC; component-based; Event driven.
  • TinyOS concurrency: Interrupts (asynchronous) and Task scheduling (synchronous). Task scheduling done with a FIFO queue.
  • Model executed on FDR2.

Network modeling:
  • Time Flooding Synchronization protocol: same time base (only says all nodes will have the same time, whatever it is).
  • Model maxed out at seven nodes.

Further refinements:
  • Network level models against node models. High -> Low level.
  • Check fault tolerance in a network.

The role of Industry and Universities in developing successful technology Industries

Tony's involvement:
  • Governance, Strategy building, Innovation management, Commercialisation of technology, Business growth.
  • Phitek, Senztek, Auckland UniServices, Auckland materials accelerator, FRST, Vesper Marine, BEP Marine, SiFE.
Universities:
  • Driven by knowledge, not financial success.
  • Science led research has long lead times to completion (esp biotech).
  • Little knowledge of market and competition.
  • Commercialising research:
    • validates the quality and relevance of the research.
    • builds status.
Companies seldom engage in fundamental research.

University technology transfer companies:
Good to go to the company's CEO and build a relationship there.

Good entrepreneurs delegating work to others. Bad entrepreneurs do all the work themselves.

Catch-22 with patent protection: Have to wait for patent to come through before product/service can be released; once you have the patent you need to be prepared to fight infringements - can be a stumbling block for start-ups since cash is limited.

If there's one idea, there must be another that goes with it?

Spark: Ideas 2 Business Workshop

Summary of the workshop:

Venture summary
  • Write for the opportunity, not the features. The sections on finance, marketing, etc are there to see if you can follow through with the opportunity.
  • What is the unique value proposition? How does it scale if you took the idea out of NZ.
  • Risk and reward.
  • Having good credentials isn't very important. Venture capitalists/Angels can provide the right people if needed.
  • "Tell me what I want to hear so I can get you there".

Teams
  • Teams don't have much in way of hierarchy.
  • "We're all in this together".
  • Technical questions raised within a company usually traverses down through a hierarchy of roles rather than to team; team disintegrates into a hierarchy or responsibilities.
  • Keep the differentiation among team members but need to keep the team integrated.

Market validation
  • Customers are interested in what they're buying in terms of benefits rather than features.
  • What is the pain point? What is the thing that customers feel threatened or incapacitated by?
  • "Product/service X has feature Y. So what?"
  • Creating a habit.
  • Don't have a solution looking for a problem.

Sales and marketing
  • Build a relationship.
  • Help people buy. Don't sell to them.
  • Don't close the sale when people come to you.

Funding
  • Sources close to you: Friends, Family, Foes, and Fools.
  • Speaker was entertaining so I forgot to write down notes :-p
  • Speaker was from the ICE House so a bit of publicity for their funding rounds.

Financials
  • Analogy: A person can live on just water for extended periods but cannot live for long with no air. A business can operate with a cash reserve (shareholder funds) for extended periods but cannot operate very long with no cash flow.
  • How well can the business turn assets into sales.
  • Assets = (Stock + Debtors) + Fixed assets.

Intellectual Property
  • Patent -> Time and Money.
  • Time to market: Is it worth sacrificing just to get a patent?
  • Trade secret: Coke, KFC.
  • Copyright is automatic.
  • Not much benefit in registering a trademark.
  • Case study: Satellite Spies

Product
  • Camera accessory: Orbis Flash
  • Prototype made.
  • Lawyer was consulted on patenting. Non-Disclosure Agreement used when speaking to people about the idea.
  • Savings used to create real prototype.
  • Simple market validation by asking friends and people on forums.
  • Finding the right manufacturer in NZ and China.
  • Entrepreneur also needs to be a salesperson.
  • Publicity: Forums, email database, website, YouTube, mavens, banner ads, product reviewers.
  • Masters Program to give customers ownership of the product success.
  • 3rd party logistics for shipping.
  • Crossing the chasm. Technology adoption. Each section is vertically integrated but the sections are not horizontally integrated.
  • Make. Sell. Count.

Doctoral forum

Creating the hole and subsequently fulling it. Originality in the title and the thesis. Social changing or general outcome dependent on another outcome. Explicitly say where the thesis is original and valuable.

Originality cannot be measured as there is nothing to measure against.

Use phrases that indicate originality and contribution. "this extends the classical approach" "these findings have the implications"

Coherent story. Clarity of argument. Link between chapters. Don't have a solution hunting for a problem. Incompleteness in ground work.

MCC CMC Markets

Contracts for difference. Entry and exit prices only. Don't own the underlying product.

  • Individual share cfd
  • Market sectors
  • Indices
  • Forex and metals
  • Treasuries and commodities

Exposure is the killer. Margin call. Can't go below threshold or account will be liquidated.

Open Flash Chart 2 - Python API

Version 2.10 of this library/module was re-written from scratch to be much easier to use. It removes the need to call functions when adding chart attributes and makes for an intuitive usage. The library is also significantly smaller than previous versions.

It is hoped that this new library can cater for new attributes added to Open Flash Chart without having to make modifications.

This library does take the liberty of assuming the programmer is *smart*. The library does not do any lexical or grammar checking.

Python instance attributes
Every instance of a class has a collection of attributes that can be set and retrieved. This Python library exploits this fact to give a dot-notation interface to setting Open Flash Chart attributes.

class Chart
The Chart class can be used in multiple situations where a container is required: chart data; custom value; group of elements.

Postgraduate place, medical, supervisor problems, wave, pgsa,

Postgraduate place, medical, supervisor problems, wave, pgsa,

The transition from taught learning to research:
Very careful speaker. You're now the person defining the question and answering it as well. 50% drop out rate by 4th year: reasons are more than just academic reasons. Pedantic work.

Make an original contribution, international standards, demonstrate knowledge of literature, satisfactory in its methodology.

Punctuation festival. Decisions. Self audit.


Theory

Assumptions are important. Perceptions can see through changing assumptions. Empirical for objectivity; connect facts together to form the truth. Exegentic for collecting recounts to form the truth. Qualitative for collecting subjectives to form the truth. Research approach.

If you were to cross the road and have to take note of all the stimuli around you, you would be uncapavle of crossing the road. Must filter out things but then you are limiting yourself in scope.

Language is a metaphor.

Custom Instruction, Avalon MM Slave, Verilog

Managed to get a custom instruction to work without much incident which was a shocker.  Didn't think I was up to the task.  Just have to make sure to specify appropriate interface signals like "custom_instruction_slave".  System generation and synthesis was pretty easy.  Using the new custom instruction was also easy as it's exposed as a #define-d macro in the System.h file.

I also managed to create my own Avalon MM Slave component.  Just had to specify the necessary slave interface ports and test that the component was behaving as expected before making my own SOPC component for use in a system.  It worked first time so I was very happy that I didn't have to trouble shoot anything.

In extending my Avalon MM Slave component, I hit a few behavioural bugs and I'm not sure if it's because I don't understand Verilog enough or because of a problem in the synthesised circuit.  My problems/glitches mainly came from the use of multiple edge triggered signals in a sensitivity list and the assignment of asynchronous signals in a clocked always body.
