According to Evangelista(2008) the university’s Student Information System (SIS) of Nueva Vizcaya StateUniversity is a secure, web accessible interactive computer system that allows user access to gradereports, transcripts, schedule of classes, and remaining balance for the semester and register for classesonline. Through the system, students would be assigned a unique identification number. All data to andfrom the university would use that unique identifier. The use of individual student records would: 1)Increase the admissions capacity to follow a student’s progress over time; 2) provide better quality datato drive more enlightened policy decisions resulting in enhanced educational opportunities for allstudents; 3) reduce data collection burden through a web enabled SIS; and 4) as a tool of parents inmonitoring the academic performance of their children

Tom is having a problem with his washing machine. he notices that the machine vibrates violently at a frequency of 1500 rpm due to an unknown rotating unbalance. the machine is mounted on 4 springs each having a stiffness of 10 kn/m. tom wishes to add an undamped vibration absorber attached by a spring under the machine the machine working frequency ranges between 800 rpm to 2000 rpm and its total mass while loaded is assumed to be 80 kg a) what should be the mass of the absorber added to the machine so that the natural frequency falls outside the working range? b) after a first trial of an absorber using a mass of 35 kg, the amplitude of the oscillation was found to be 10 cm. what is the value of the rotating unbalance? c) using me-3.5 kg.m, find the optimal absorber (by minimizing its mass). what would be the amplitude of the oscillation of the absorber?
