Design Patterns

A pattern is a proven solution to a problem in a context.
Christopher Alexander says each pattern is a three-part rule which expresses a relation between a certain context, a problem, and a solution.
Design patterns represent a solutions to problems that arise when developing software within a particular context.
i.e Patterns = problems.solution pairs in a context

design of hydraulic service jack project pdf

Every hydraulic jack has six main components:

1. A RESERVOIR to hold hydraulic fluid.

2. A PUMP that draws fluid from the resevoir on it's up, suction or intake stroke then creates pressure on it's down/power stroke pushing the fluid through a..

3. CHECK VALVE which after allowing fluid to pass from the resevoir to the pump now 'checks' off the return port to the resevoir and directs the pressurized fluid to the..

4. MAIN CYLINDER ....etc

ABSTRACT
Many system-on-chip (SoC) integrated circuits contain embedded cores with different scan frequencies. To better meet the test requirements for such heterogeneous SoCs, leading tester companies have recently introduced port-scalable testers, and Many IP core design software like Xilinx, Leonardo Spectrum, and Modelsim etc which can used to design ip core like DMA ,Interrupt Controller etc .These Ip core can be Power aware an Implement on soc by choosing different design tech ....etc

project report in hydraulic press design in pdf

ABSTRACT
In an attempt to alleviate the problem of the dearth of equipment in our laboratories in most of our higher institutions, a 30-ton hydraulic press was desgined, constructed and tested using locally sourced materials. The principal parameters of the design included the maximum load (300 kN), the distance the load resistance has to move (piston stroke, 150 mm), the system pressure, the cylinder area (piston diameter = 100 mm) and the volume flow rate of the working fluid. The major compone ....etc

Integrating Structural Design and Formal Methods in RealTime System Design

Formal methods have been advocated as one of those techniques that can produce highquality software and hardware systems that has been demonstrated to come in ontime, within budget, and satisfy procurer requirements. They are, however, perceived to be difficult to use and unsuitable for presentation to nonspecialists. In addition, they have been criticized for paying too little attention to the system development process.

Traditional structur ....etc

Common Emitter BJT Amplifier Design Current Mirror Design


Some Random Observations
Conditions for stabilized voltage source biasing
Emitter resistance, RE, is needed.
Base voltage source will have finite resistance, RB.
needs to be much larger than RB.
Small RB - relative to RS - will attenuate input signal.
Larger RE permits larger RB, but results in lower gain.
Gain = -RC/RE for RE >> re.
Split RE with bypassing increases gain.
Requires large bypass cap ....etc
