Minsky – Steve Keen's Debtwatch. Minsky: Latest News. Russell Standish has been working on Minsky thanks to the extra funds raised by the donate button below. He has produced a beta which is a substantial improvement over the release version currently on the Sourceforge home page. It adds: an equation viewer–so you can design a model and instantly see the equations behind it from within Minsky (as well as export them to La. Te. X); A differential operator, so you can calculate rates of change (and in typical Russell style, this is no ordinary numerical approximation but a full symbolic differential system, so the approximation problems that apply with (to my knowledge) all other system dynamics program differential operators don’t apply to Minsky); A large number of bug fixes.
With the caveat that beta versions almost always have bugs, this version is very close to a new release candidate and I would recommend using it rather than the stable release: Minsky Beta Page. Keep Russell Standish coding Minsky. Minsky has been developed thanks to two grants: an initial US$1.
INET, and crowdfunding of $7. Kickstarter. With other amounts from individual donor, that has funded about 2. Minsky, Professor Russell Standish. I will be applying for other grants now that I am based in the UK, but in the meantime more funding is needed to keep the development rolling and to reserve Russell’s skills for Minsky. So please donate via the Paypal link above: the funds go directly to Russell, and the money raised so far–about $8,0.

Source. Forge Project of the Month for January 2. We’re delighted that Source.
Forge has seen fit to make Minsky it’s Project of the Month. Minsky is both a general purpose system dynamics program, and the first such program specifically designed to support the building of monetary models of the economy.
Our design objective has been to make it as intuitive as possible to use, while supporting various advanced features–such as maintaining consistency between multiple monetary flow tables–in as seamless a way as possible. We hope that users will find it useful, and we would be delighted to get coding assistance from developers, user assistance in bug testing and building the help system, etc. Dr. Russell Standish and I have been working on Minsky now for almost two years now–first using a $1.
K from INET’s Spring 2. K from a successful Kickstarter campaign: Russell as builder (coding in C++ and Tcl/Tk) and me as architect (playing with each release, spotting bugs and suggesting features).
It’s been a part- time endeavor: Russell, as a contract programmer, has to keep more than one iron in the fire, while I have a fair few balls in the air myself. Russell has put in about 2. That amount of coding is chicken feed compared to the millions of hours that have gone into a standard commercial product like Microsoft Word or Excel, so Minsky is still rough at the edges, and lacks a number of features that you would expect in a commercial package. But there is enough core functionality and stability in place for a first major release–the “Mun” version which can now be downloaded from Source. Forge (major iterations of Minsky are named after major thinkers in economics–we started with Aristotle). There is still only a rudimentary and incomplete Help file (did I say I had too many balls in the air?), so to make up for it I’ve recorded the following set of 1. They’re all up on You.
Tube (where the number is the series changes from 8 to 1. All the Minsky (mky) files used in the presentations are in this Zip file. So if you’re into economic modeling and you’d like to develop dynamic monetary models, Minsky now has enough features to be worth using–and it won’t face the limitations that apply to more conventional system dynamics programs, like Stella, Vensim, Vissim, etc., that make it inherently challenging to model the financial system. With Minsky and its Godley Tables, monetary modeling is a cinch (and it will get easier as we add more capabilities to the program). So please, download the program, join our beta- testing group, and start building monetary macroeconomics. If you’re a developer with time to devote to this project, immediate needs include: Sprucing up plots; Copy and paste support files; Multiple files open at once; Building a La.
Te. X viewer into Minsky; Medium term needs include: A direct La. Te. X editor with seamless transfer between the equation pane and the canvas pane; Adding Social Accounting Matrix support for equation consistency checking; The long term objectives include: Transform a “scalar” economic model into a “vector” with monetary and physical input- output dynamics with one click; Multiple economy support with financial and physical flows between economies, currency conversion, etc.; Data importing, manipulation and nonlinear parameter fitting.

Embedded system - Wikipedia, the free encyclopedia. An embedded system is a computersystem with a dedicated function within a larger mechanical or electrical system, often with real- time computing constraints. Embedded systems control many devices in common use today.
This comes at the price of limited processing resources, which make them significantly more difficult to program and to interact with. However, by building intelligence mechanisms on top of the hardware, taking advantage of possible existing sensors and the existence of a network of embedded units, one can both optimally manage available resources at the unit and network levels as well as provide augmented functions, well beyond those available. CPUs with integrated memory or peripheral interfaces). In either case, the processor(s) used may be types ranging from general purpose to those specialised in certain class of computations, or even custom designed for the application at hand. A common standard class of dedicated processors is the digital signal processor (DSP). Since the embedded system is dedicated to specific tasks, design engineers can optimize it to reduce the size and cost of the product and increase the reliability and performance. Some embedded systems are mass- produced, benefiting from economies of scale.
Embedded systems range from portable devices such as digital watches and MP3 players, to large stationary installations like traffic lights, factory controllers, and largely complex systems like hybrid vehicles, MRI, and avionics. Complexity varies from low, with a single microcontroller chip, to very high with multiple units, peripherals and networks mounted inside a large chassis or enclosure. History. At the project's inception, the Apollo guidance computer was considered the riskiest item in the Apollo project as it employed the then newly developed monolithic integrated circuits to reduce the size and weight. An early mass- produced embedded system was the Autonetics D- 1. Minuteman missile, released in 1.
When the Minuteman II went into production in 1. D- 1. 7 was replaced with a new computer that was the first high- volume use of integrated circuits. Since these early applications in the 1. An early microprocessor for example, the Intel 4. In 1. 97. 8 National Engineering Manufacturers Association released a . By the early 1. 98. Microcontrollers find applications where a general- purpose computer would be too costly.
A comparatively low- cost microcontroller may be programmed to fulfill the same role as a large number of separate components. Although in this context an embedded system is usually more complex than a traditional solution, most of the complexity is contained within the microcontroller itself. Very few additional components may be needed and most of the design effort is in the software. Software prototype and test can be quicker compared with the design and construction of a new circuit not using an embedded processor. Varieties. Computer networking uses dedicated routers and network bridges to route data.
Consumer electronics include personal digital assistants (PDAs), mp. DVD players, GPS receivers, and printers.
Household appliances, such as microwave ovens, washing machines and dishwashers, include embedded systems to provide flexibility, efficiency and features. Advanced HVAC systems use networked thermostats to more accurately and efficiently control temperature that can change by time of day and season. Home automation uses wired- and wireless- networking that can be used to control lights, climate, security, audio/visual, surveillance, etc., all of which use embedded devices for sensing and controlling.
Transportation systems from flight to automobiles increasingly use embedded systems. New airplanes contain advanced avionics such as inertial guidance systems and GPS receivers that also have considerable safety requirements. Various electric motors . Automobiles, electric vehicles, and hybrid vehicles increasingly use embedded systems to maximize efficiency and reduce pollution. Other automotive safety systems include anti- lock braking system (ABS), Electronic Stability Control (ESC/ESP), traction control (TCS) and automatic four- wheel drive.
Medical equipment uses embedded systems for vital signs monitoring, electronic stethoscopes for amplifying sounds, and various medical imaging (PET, SPECT, CT, MRI) for non- invasive internal inspections. Embedded systems within medical equipment are often powered by industrial computers. In dealing with security, the embedded systems can be self- sufficient and be able to deal with cut electrical and communication systems. A new class of miniature wireless devices called motes are networked wireless sensors.
