## What is podia Scan?

The foot Scan system Podiascan system provides podiatrist and biomechanists with an economical and efficient method to measure static / dynamic plantar foot pressure distribution. The Footscan Podiascan system produces permanent high resolution image(foot scan) of the pressure distribution across the plantar surface.

## How does F-scan work?

FScan is a disk scheduling algorithm to determine the motion of the disk’s arm and head in servicing read and write requests. It uses two sub-queues. During the scan, all of the requests are in the first queue and all new requests are put into the second queue.

What is meant by the term pressure time integral?

The pressure–time integral is mostly defined as the area under the peak pressure time curve, although alternative definitions exist. Elevated levels of pressure–time integral have also been associated with plantar ulceration, but to date only in retrospective studies (Stess et al., 1997).

### What is C Scan OS?

Circular SCAN (C-SCAN) scheduling algorithm is a modified version of SCAN disk scheduling algorithm that deals with the inefficiency of SCAN algorithm by servicing the requests more uniformly.

### Which is better scan or C-scan?

In C-SCAN disk scheduling algorithm, the only difference with respect to SCAN algorithm is that, it is designed to provide more uniformity in waiting time….Example:

S. No. SCAN Scheduling Algorithm C-SCAN Scheduling Algorithm
1. It is also known as Elevator Algorithm. It is also known as Circular Elevator Algorithm.

Why is C-scan better than scan?

The only difference between SCAN and CSCAN is that in CSCAN, it begins its scan toward the nearest end and works it way all the way to the end of the system. Once it hits the bottom or top it jumps to the other end and moves in the same direction,unlike the SCAN which moves back to upside using the same path.

#### Is C-look more efficient than C-scan?

C-LOOK algorithm has the best performance in all disk scheduling algorithms. C-LOOK algorithm can handle requests more effectively than C-SCAN. In above example of C-SCAN algorithm, the head moves from 53, serves all requests in right direction till it reaches the other end.

#### How is C-Scan calculated?

When we reach at the beginning(left end) reverse the direction. While moving in right direction it services all tracks one by one. While moving in right direction calculate the absolute distance of the track from the head. Increment the total seek count with this distance.

Which is better C-scan or C-look?

C-LOOK provides low variance in response time and waiting time. C-SCAN provides uniform waiting time and response time. In C-LOOK algorithm, there is an overhead of finding the end requests. C-SCAN algorithm causes more seek time as compared to C-LOOK.

## Which is better algorithm scan or look?

The main reason behind the better performance of LOOK algorithm in comparison to SCAN is because in this algorithm the head is not allowed to move till the end of the disk. Difference between SCAN and LOOK Disk scheduling algorithms: This algorithm scans all the cylinder of the disk back and forth.

What is C-SCAN algorithm?

Circular SCAN (C-SCAN) scheduling algorithm is a modified version of SCAN disk scheduling algorithm that deals with the inefficiency of SCAN algorithm by servicing the requests more uniformly. Like SCAN (Elevator Algorithm) C-SCAN moves the head from one end servicing all the requests to the other end.
