What is scatter seed?

a scatter seed is a pack of seeds that scatter all over


What is a frequency Diagram?

A frequency diagram means of displaying raw data in a graphical form that is easier to interpret. Commonly used frequency diagrams are bar charts, histograms, pie charts, and scatter diagrams.


What are types of DMA?

DMA is a mechanism through which a hardware device can transfer data to or from memory without using the processor. The processor is required to set up the transfer, and the device will signal the processor when it has completed the transfer. The advantage of this system is that the processor can perform other tasks while the DMA transfer is being performed. There are several types of DMA used in Windows 2000 and later: ; Common-buffer DMA : Common-buffer DMA is performed when the system can allocate a single buffer that is accessible by both the hardware and the software. The driver is responsible for synchronizing accesses to the buffer. The memory is not cached, making this synchronization easier for the driver. After setting up a common buffer, both the driver and the hardware can write directly to the addresses in the buffer without any intervention from the HAL. ; Packet DMA : Packet DMA is performed when there is a single existing buffer that must be mapped for use by the hardware. An example of using packet DMA is the transfer of a file from memory to a disk. Using common-buffer DMA in this situation would be wasteful, because the file would have to be transferred to the common buffer before the hardware could transfer it to the disk. Instead, the HAL is consulted; it gives the driver the information it needs to help the hardware find the actual buffer in memory. This operation is complicated by the need for the routines involved to work across different architectures. ; Scatter/gather DMA : Scatter/gather DMA is a shortcut method that sets up several packet DMA transfers at once. If you are transferring a packet over the network, for example, each part of the network stack adds its own header (TCP, IP, Ethernet, and so forth). These headers are all allocated from different places in memory. In this case, the scatter/gather DMA saves time by issuing a batch request to the HAL to map each header plus the data segment for access by the hardware. Instead of having to call the packet DMA routines on each part of the packet, this method calls each routine once, and lets the HAL be responsible for mapping each one individually. Note Scatter/gather capability does not mean that the device can use the scatter/gather routines. Scatter/gather capability refers to a flag in the device description that indicates that the device is able to read or write from any area in memory, instead of just a certain range. ; System DMA : System DMA is performed by programming the system DMA controller on the motherboard to do the transfer directly. Only ISA cards can use system DMA.


What does high value of weibull modulus indicate?

The Weibull Modulus is related to the distribution of flaws in a brittle specimen. It is important to note that it isn't relate to the size of the flaws. To find the Weibull Modulus, many samples of the same material are tested, in tension, to failure. If the flaws are evenly distributed throughout the specimen, the data from the the tests will show little statistical scatter and result in a high value of the Weibull Modulus. Conversely, if the flaws are unevenly distributed causing the test data to differ greatly from sample to sample (greater flaws means more opportunities for stress concentrations at those flaws, causing a lower failure stresses) then there will be large statistical scatter in the test data, and the Weibull Modulus will be measured as a lower number.
