Aset j of jobs are to be scheduled on m identical machines. each job j 2 j has a processing requirement pj (denoting the number of machine days required to complete the job), a release date rj (representing the beginning of the day when job j becomes available for processing), and a due date dj rj + pj (representing the beginning of the day by which the job must be completed). we assume that a machine can work on only one job at a time and that each job can be processed by at most one machine at a time. however, we allow preemptions (i. e., we can interrupt a job and process it on di§erent machines on di§erent days). the scheduling problem is to determine a feasible schedule that completes all jobs before their due dates or to show that no such schedule exists. formulate this problem as a maximum áow problem.

Creating "smart interfaces" in all sectors of industry, government, and the public arena is one of the fastest growing hct areas. these interfaces model, interpret, and analyze such human characteristics as speech, gesture, and vision. the field of biometrics, in which humans authenticate themselves to machines, is an area of considerable interest to hct practitioners. fingerprint scans are one of the most frequently used biometric options, and this article, biometric student identification: practical solutions for accountability & security in schools, makes a case for the implementation of fingerprint scans in schools. critique the article, and answer the following questions: according to the author, what are the main benefits of adopting fingerprint scans in schools for student identification? according to the author, what are the main drawbacks of adopting fingerprint scans in schools for student identification? do you agree with the author's assessment of the pl
