Mr.Khalid hussein aljewary




I have completed the Bachelor degree in electrical engineering science  from Baghdad university ,college of engineering ,electrical engineering department in 1981 .

I have completed the M.Sc degree in electronic and communication science from Al-mustansiryah university ,college of engineering in 2000 .

I have worked more than (18) years with Diyala company for electrical industries that belongs to the ministry of industry and minerals .

At the start of 2004 my services have been transferred to the ministry of high education and scientific researches .

I have done as a chief of computer science department ,and also a chief for electronic engineering department in college of engineering ,diyala university .

Now I am still working in communication engineering department as a lecturer .

I have published (6) papers in different journals ,where our papers focused on industrial engineering control .
