## What are controlled drugs NHS?

The Controlled Drugs (Supervision of Management and Use) Regulations 2013 came into force in England on 1st April 2013. Controlled drug – any drug belonging to schedule 1, 2, 3, 4 or 5 of the Misuse of Drugs Regulations 2001.

## What is DDA algorithm for line with example?

DDA Algorithm is explained by taking some examples. Remember the steps: If slope (m) is less than 1 (m<1) then increment x as x1+1 and calculate y as y1=y1+m. If slope (m) is greater than 1 (m>1) then increment y as y1+1 and calculate x1=x1+1/m.

## What is meant by DDA?

In computer graphics, a digital differential analyzer (DDA) is hardware or software used for interpolation of variables over an interval between start and end point. DDAs are used for rasterization of lines, triangles and polygons.

## What are the advantages of DDA algorithm?

Advantages of DDA AlgorithmIt is the simplest algorithm and it does not require special skills for implementation.It is a faster method for calculating pixel positions than the direct use of equation y=mx + b. … Floating point arithmetic in DDA algorithm is still time-consuming.The algorithm is orientation dependent.

## What is DDA What are the disadvantages of DDA algorithm?

Disadvantages of DDA Algorithm- There is an extra overhead of using round off( ) function. Using round off( ) function increases time complexity of the algorithm. Resulted lines are not smooth because of round off( ) function. The points generated by this algorithm are not accurate.

DDA Advantages of DDA algorithm; a) Faster than the direct use of line equation and it does not need any floating point multiplication. Disadvantages of DDA algorithm; a) Floating point Addition is still needed b) Precession loss is possible because of rounding of the points. c) The algorithm is orientation dependent.

## What are DDA drugs?

Drugs of dependence (often referred to as ‘DDAs’, in reference to the former act under which they were regulated) are prescription medicines that have a recognised therapeutic need but also a higher potential for misuse, abuse and dependence (SA Health 2017).

## Which is better DDA vs Bresenham?

The main distinction between DDA algorithm and Bresenham line algorithm is that, the DDA algorithmic rule uses floating purpose values whereas in Bresenham, spherical off functions is used. … DDA algorithm is less efficient than Bresenham line algorithm. While it is more efficient than DDA algorithm.

## Which is the clipping algorithm?

There are two common algorithms for line clipping: Cohen–Sutherland and Liang–Barsky. A line-clipping method consists of various parts. … Determining which portion of the line is inside or outside of the clipping volume is done by processing the endpoints of the line with regards to the intersection.

## How many types of drugs are there?

There are four main groups of drugs, divided according to their major effects, plus a few substances that do not easily fit into any category. The main categories are: stimulants (e.g. cocaine) depressants (e.g. alcohol)
