The speed of an induction motor depend on the frequency of the supply voltage 60Hz in the USA and 50Hz in most other country's and the speed can only be controlled by varying the frequency, the way to do it is to rectify the AC to DC and convert it back to AC but with another frequency. I'm planing to post a project on my website soon, so look out for it at http://www.patenttrade.net

What is problem with traditional software development?

In traditional software development method there were only two steps that is build code and fix. This was not an efficient method so new life cycle models were introduced.


Why scr is called as bidirectional an controlled device?

Because it can control input voltage in both halves of cycle.


When are pressure cycle ventilators preferred over volume cycle ventilators?

Do you mean pressure control and volume control?? instead of cycle? IF YES, Pressure control is used when you want a specific peak airway pressure aka PIP it is also used the mode of choice in the NICU and PICU Volume control is used when you want to reach a desired tidal volume. These are also dependent on the patients lung characteristics. It is also important to remember that in either mode it is possible to manipulate the other variables such as inspiratory flow, rate, rise time and I:E (to name a few) to obtain or control volume or pressure.

3 types of DMA transfer modes?

· Block transfer DMA controller takes the bus control by CPU. CPU has no access to bus until the transfer is complete. During this time CPU can perform internal operations that do not need bus. This is a common and popular method with modern microprocessors. · Cycle stealing This is a word-by-word transfer based on CPU cycle stealing. When DMA steals a cycle, CPU is stopped completely for one cycle. Cycle stealing is not an interrupt. CPU pauses for just one machine cycle. This type of transfer takes a period of time. Some major steps of DMA cycle stealing in order to transfer data to and form memory are: · DMA needs control of the CPU · DMA must use the bus only when the CPU does not need it · CPU is suspended by DMA just before it needs to use the bus · CPU pauses for one bus cycle · DMA transfers one words and then returns the control to CPU · The overall effect is to cause the CPU to execute more slowly · Interleaved DMA. It is similar to block transfer technique, here DMA controller takes the control of system bus only when CPU is not using it. For example, performing an ALU operation or incrementing a counter. The data transfer by this kind of method takes a period of time.


What is cycle stealing with respect to Operating System?

We encounter cycle stealing in the context of Direct Memory Access (DMA). Either the DMA controller can use the data bus when the CPU does not need it, or it may force the CPU to temporarily suspend operation. The latter technique is called cycle stealing. Note that cycle stealing can be done only at specific break points in an instruction cycle.


What is cycle stealing technique?

Cycle stealing is a technique used in accessing a computer's RAM without having to pass through the CPU. It is similar to direct memory access or DMA.


Will anything bad happen if you take a birth control pill in the middle of your cycle?

No, it will become fully effective after about 10 days, and your cycle will adjust to the pill cycle. Always use a second method of contraception!


What is cycle-stealing?

A CPU design technique that periodically "grabs" machine cycles from the main processor usually by some peripheral control unit, such as a DMA (direct memory access) device. In this way, processing and peripheral operations can be performed concurrently or with some degree of overlap.


What if you want to use the rhythm method?

The rythm method is a calendar based method of birth control. It is most commonly used by Catholics who follow the churches teaching that other methods of birth control are sinful. An example of the rhythym method would be if a woman had her menstrual cycle for 32 days, day 22 of the cycle would mean the infertile period would begin.


Is it okay to start taking the pill a couple of days after your period starts or should you just wait till the next month to start taking it?

You can start the birth control pill at any time in your cycle using the Quick Start method. Just use a back up method of birth control for the first seven days of the first cycle.


Do i have to wait for my period to take a contraceptive pill?

No, you can start the birth control pill at any time in your cycle using the Quick Start method. Be sure to use a backup method of birth control, like condoms or abstinence from vaginal sex, until you've been taking your pill for at least seven days. If you still haven't had your period after a cycle of pills, take a pregnancy test.


Can you take birth control on the first day of your period or the fifth day?

You can start birth control on any day of your cycle. If you start within the first five days of your cycle, it's immediately effective; otherwise, use a back up method of birth control, like condoms or abstinence from vaginal sex, until you've taken the birth control for seven days.


Define the project control cycle?

project control cycle is the cycle of the project. it consist of the maximum levels of planning and authority. it tells about the control over the modules of the project. the project is consist of the module and the cycle gives us a brief view over the control on the project cycle. the project cycle consist of different level. all the working of the project is based on these levels of the cycle. basically, the project control cycle is divided in to different parts and each part is based on the control of the project level... DON


Can you start the birth control pill two weeks after an abortion.?

You can start the birth control pill at any time, but if you didn't start them the day of the abortion, you should use a back up method of birth control for the first seven days of the first cycle.


How will it take the Nuva Ring to work if it's inserted AFTER my cycle namely 2 days after?

Use a back up method of birth control, like condoms or abstinence from vaginal sex, for at least seven days after starting the first cycle.
