Zulkarnain Hassan is a senior lecturer at the School of Environmental Engineering, Universiti Malaysia Perlis (UniMAP). He is a member of the International Association of Hydrological Sciences (IAHS), Board of Engineering Malaysia (BEM), and Malaysian Hydrological Society (MHS).

Zulkarnain focused on the research to improve the prediction of flood characteristics through the development of new analytical probabilistic models, the use of data from general circulation models, and through the better characterization of risk and uncertainty.

His research interests include (1) hydrology and water resources, (2) artificial intelligence, (3) optimization, (4) analytical probabilistic approaches, (5) general circulation models and climate change, (6) risk and uncertainty analysis, and (7) statistical.

For details see his CV (email upon request) or click on the tabs provided in the menu above.

Note: Please contact me if you are interested in pursuing Masters or Ph.D. level research as there are a number of interesting projects to work on. I am looking for students with backgrounds in quantitative fields such as physics, mathematics or atmospheric science. – zulkarnain

# Normalize values in a matrix to be between 0 and 1 (Matlab Tips)

I’m run a function in Matlab and it requires a matrix of variables within 0 and 1. The way to normalize the values to be between 0 and 1, and transform back to the original matrix as follows:

```b = [10; 0; 1; 1];

%% normalized matrix B to 0 and 1
normB = b - min(b(:));
normB = normB ./ max(normB(:))

%% transform normalized matrix B to the original matrix
B_sim = normB_sim .* max(b(:))```

Make sure, when transforming normalized matrix to the original matrix, you provided the maximum value of the original matrix. It not, the code cannot be run.
