Teaching databases to hundreds of engineering students

Yearly, we teach basic database courses to about two to four hundred engineering students with different backgrounds and different requirements. We also have a limited amount of teacher resources. To deal with this situation we have organized our course topics in the form of modules. A database course is then defined by a number of modules together with a mini-project. We discuss this organizat...

Her only cardiovascular risk factor was a family history of atherosclerosis, with her mother suffering from myocardial infarction at 50. Her body mass index was 20 kg/m and the main abnormality on examination was the eye sign shown in . Fasting serum cholesterol and low density lipoprotein were b...

Optimal P{cyclic Sor

Our purpose in this paper is to extend p{cyclic SOR theory to consistent singular systems and to apply the results to the solution of large scale systems arising, e.g., in queueing network problems in Markov analysis. Markov chains and queueing models lead to structured singular linear systems and are playing an increasing role in the understanding of complex phenomena arising in computer, comm...
