JumpSoft. JumpSoft Inc is an American software company that provides application performance management (APM) software. JumpSoft is a committee member for several industry web services standards including web services interoperability and cloud application management for platforms. In 2012 JumpSoft co-proposed a new industry web services standard for managing cloud applications on PaaS environments called CAMP.

Open Standards Development

Cloud Application Management for Platforms (CAMP)
CAMP is an open web services standard under development as an API for managing public and private cloud applications. In 2012 JumpSoft co-proposed CAMP through the Organization for the Advancement of Structured Information Standards (OASIS).

CAMP leveraged similarities between commercial and open-source PaaS products to attempt a simple API that is language-, framework-, and platform-agnostic as an alternative to closed APIs from cloud services vendors. Using CAMP, companies can migrate their cloud applications from one PaaS vendor to another by mapping the requirements of applications to the specific capabilities of the underlying platform.

Joab Jackson of IDG News Service said "CAMP is the first attempt, as far as the development team knows, to standardize PaaS control commands. Although the use of PaaS services has grown dramatically in the past few years, through services like Amazon's Elastic Cloud Compute (EC2) and Microsoft Azure, each vendor offers its own console to users, making the migration of workloads from one service to the next difficult."

The other organizations that proposed CAMP include Oracle, Redhat, Software AG and the US Department of Defense.

Web Services Interoperability (WS-I)
JumpSoft is a sponsor member for the OASIS Web Services Interoperability (WS-I) technical committee.

John Dudley North. John Dudley North (1893–11 January 1968), CBE, HonFRAeS, MIMechE, was Chairman and Managing Director of Boulton Paul Aircraft.

Born at 18 Kinver Road North, Peak Hill, Sydenham, London in 1893 and educated at Bedford School, North became Chief Engineer for Claude Graham-White of the Grahame-White Aviation Co. Ltd., before the onset of World War I. This was a very responsible post for a young man in a young company within a fledgling and vital industry. He moved on in 1915 to become superintendent of the aviation department of Austin Motor Company. In 1917 he joined Boulton Paul in Norwich and commenced his long association with the company and its aircraft division, Boulton Paul Aircraft, which set up in Wolverhampton before the Second World War. Mr North rose to the position of managing director of Boulton Paul Aircraft in 1951, and was also the company’s chief engineer. He retired in 1954.

During North’s time with Boulton Paul he was involved in the design of many aircraft, not least the Overstrand, Sidestrand, Defiant and the R101 airship, of which the company built the hull.

In 1941 North was Vice President of the Society of British Aerospace Companies (SBAC). He was made an honorary fellow of the Royal Aeronautical Society in May 1961 and he made CBE in 1962.

North married in 1922 Phyllis Margaret, daughter of Edward Huggins, Clerk of the Norwich Board of Guardians. The couple had two daughters.

John Dudley North died on 11 January 1968 at his home, Eversley, Oldbury, Bridgnorth, Shropshire, aged 75.

Chandrapur–Padghe HVDC transmission system. The Chandrapur–Padghe HVDC transmission system is an HVDC connection between Chandrapur and Padghe (near Mumbai) in the state of Maharashtra in India, which was put into service in 1999.

It connects the coal-fired Chandrapur Super Thermal Power Station to the major load centre of Mumbai.  The project has a  long bipolar overhead line.  The transmission voltage is ±500 kV and the maximum transmission power is 1,500 megawatts. The scheme uses thyristor valves, arranged in a single twelve pulse bridge per pole.  The project was built by ABB and BHEL, and is owned by Maharashtra State Electricity Board (MSEB).

The eastern (Chandrapur) converter station is located  from the Chandrapur back to back HVDC station. The close proximity of the two converter stations meant that the control systems needed to be carefully coordinated, a task made more challenging by the fact that the two stations were built by different manufacturers.  To address this problem a series of joint simulation studies, involving the control equipment from both converter stations connected to a common simulator, was performed.

Backward invention. Backward invention is a product strategy in international marketing in which an existing product may have to be re-engineered or dumbed down by the company to be released in Less Developed Countries, often at a cheaper rate.

Doing so can often breathe new life into an obsolete product by the company or even target people too poor to afford the actual product.

Definition
There are two definitions for a backward invention:
 "Reintroducing earlier product forms that can be well adapted to a foreign country’s needs."
 "Redesigning and producing a product for specific foreign markets after it is obsolete in industrialized countries."

Examples
The National Cash Register Company reintroduced a dumbed down version of its crank-operated cash register at a lower cost for South American and African markets.

Another example would be of the German book-publishing giant Bertelsmann in Ukraine, where the average person's salary is less and bookstores are hard to find.  The old-fashioned book club is enjoying huge popularity there, whereas it has seen a decline in its Book-of-the-Month and Literary Guild units in both the United States and Europe. In Ukraine, however, these clubs are seeing profit margins triple the 4% global average. Bertelsmann also finds that these clubs draw a younger following than in the United States. The publisher also keeps prices low because its main competitor in Ukraine is the open air book market, where books sell very cheaply.

Advantages
  Increase in revenue due to increase in sales.
  Wider reach and brand awareness and brand popularity in newer markets.
  Breathe new life into an obsolete product by the company (Cycle-recycle pattern of the product life cycle)
  Appeal to the lower segment of the socio-economic audience.

Kubo formula. The Kubo formula, named for Ryogo Kubo who first presented the formula in 1957, is an equation which expresses the linear response of an observable quantity due to a time-dependent perturbation.

Among numerous applications of the Kubo formula, one can calculate the charge and spin susceptibilities of systems of electrons in response to applied electric and magnetic fields.  Responses to external mechanical forces and vibrations can be calculated as well.

General Kubo formula
Consider a quantum system described by the (time independent) Hamiltonian . The expectation value of a physical quantity at equilibrium temperature , described by the operator , can be evaluated as:
,
where  is the thermodynamic beta,   is density operator, given by

and  is the partition function. 

Suppose now that just after some time  an external perturbation is applied to the system. The perturbation is described by an additional time dependence in the Hamiltonian:

where  is the Heaviside function (1 for positive times, 0 otherwise) and  is hermitian and defined for all t, so that  has for positive  again a complete set of real eigenvalues   But these eigenvalues  may change with time.

However, one can again find the time evolution of the density matrix  rsp. of the partition function  to evaluate the expectation value of

The time dependence of the states  is governed by the Schrödinger equation 
 
which thus determines everything, corresponding of course to the Schrödinger picture. But since  is to be regarded as a small perturbation, it is convenient to now use instead the interaction picture representation,  in lowest nontrivial order. The time dependence in this representation is given by  where by definition  for all t and  it is: 

To linear order in , we have
. 
Thus one obtains the expectation value of  up to linear order in the perturbation:
,
thus

The brackets  mean an equilibrium average with respect to the Hamiltonian  Therefore, although the result is of first order in the perturbation, it involves only the zeroth-order eigenfunctions, which is usually the case in perturbation theory and moves away all complications which otherwise might arise for .

The above expression is true for any kind of operators. (see also Second quantization)
