What are advantages of arrays?
It allows redundency and protection against failure, it also decreases the load on each drive (in some forms of RAID) which increases life span and efficience.
Differentiate Optimistic concurrency control and pessimistic concurrency control?
concurrency control algorithm
What is vf speed control?
It is used for sensorless motor control. With vf speed control u can control speed of any induction motor.
What is a congestion control mechanism?
Congestion control mechanisms are tools that control how backed up a substance may get. Traffic congestion control mechanisms can be stop lights, for example.
What is a derivative control?
Derivative control applied in control engineering, usually for the operation of control valves and its importance came during valve tuning. Derivative control is popularly known as anticipatory control. ( controller starts its control action, by anticipating the trend of present value (PV) of parameter.) Derivative control anticipates parameter values and and it will take control action to control the parameter with in set point. Eg: In a water heating system, water temperature is controlled by controlling steam valve opening. Let set point for water is 80°C, and derivative control will check the status of water temperature and if it is slowly increasing range ( may be due to some load change), controller will starts to control temperature by slowly closing steam valve. ( and vice versa) Actually this type control action just observe at control parameter values and initiates control action.
What is the most reliable and efficience form of communication?
not communicating at all
What are the different between effective and efficience?
Effective is adjective and effcience is noun.
Factors affecting cost behavior?
Volume Price Efficience Sales mix Production changes
What is green house effeect?
the warming of the the earth as the suns rays upon exit from the atmosphere being reflected down to earth because of green house gasses.
What are advantages of arrays?
It allows redundency and protection against failure, it also decreases the load on each drive (in some forms of RAID) which increases life span and efficience.
What has the author Philip Roger Marvin written?
Philip Roger Marvin has written: 'Multiplying management effectiveness' -- subject(s): Management, Efficience dans l'industrie, Gestion 'Administrative management' -- subject(s): Management
What is the difference between extensive and intensive agriculture?
Intensive agriculture: great production to hectare, efficience, use of fertilizers and pesticides, irrigation, mechanization, application of agricultural sciences, etc. Extensive agriculture: low production to hectare, inefficience, primitive work, etc.
Why hydrogen have zero inductive effect?
Hydrogen has zero inductive effect because it is the least electronegative element on the periodic table, with a value of 2.20 on the Pauling scale. Inductive effect occurs when a more electronegative atom in a molecule pulls electron density towards itself, affecting the distribution of electrons in neighboring atoms. Since hydrogen has a low electronegativity, it does not have the ability to attract electrons significantly and therefore does not exhibit inductive effect.
What is the function of turbocharger?
To increase the power output of an engine when needed, it does this by increasing volumetric efficience of the engine. The turbo compressies the incoming air and forcing it into the cylinders at above normal atmospheric pressure. Under boost the motor acts like it is bigger than it really is.. example a normally aspirated 2.0L engine will act like/produce the equivalent power of a 4.0l when it is boosted to aprox.14-15psi.
What are types of control in business organization?
· Feedback control · Concurrent control · Feedforward control
The standard for comparison in a experiment?
The standard for comparison in a experiment is known as a control variable. This is useful to any experiment and serves as a reference point used to draw conclusions.
A control is a?
a control is a
