Week 2: General Problem: Medical Equipment Malfunctions
Medical device malfunctions occur when equipment used by healthcare providers fails to perform efficiently because of technical issues, or when an error is caused or started by users. These mistakes can have significant consequences for patient care and safety. A Couple of years ago my friend’s grandfather passed away because of a massive insulin overdose from the failure of an insulin pump. Maintaining the safety of medical devices has a direct impact on the health and safety of patients. Patients can be harmed or injured by unsafe equipment. Proper working equipment is critical for proper diagnosis, medical care, and care for patients.
Alsohime et al. (2019) explain how some hospital sections, such as the ICU, depend on a variety of technological resources, including ventilators, vital sign monitors, infusion and injection pumps. The purpose of this study was to determine how ICU nurses approach problems
connected to medical devices in a single acute center, as well as their level of knowledge of the national reporting system for adverse events linked to medical devices. It is critical to create a framework for safe medical device operation based on international standards. ICUs are diverse work settings that are challenging. Efficient workflow in these areas is dependent on the knowledge and abilities of all team members, including medical and nursing personnel, clinical pharmacists, respiratory therapists, dieticians, porters, and technicians, whose collaborative efforts result in optimal patient care. This interdisciplinary team feature improves patient safety and the quality of care in the intensive care unit. This study has highlighted the necessity to create a framework for the safe operation of medical devices that is based on international standards. It is important that the health care providers be familiar with the existence of the reporting system.

Activity 3.8 Precision and Accuracy of
Measurement
Introduction
This concept of random and systematic errors is related to the precision and accuracy
of measurements. Precision characterizes the system's probability of providing the
same result every time a sample is measured (related to random error). Accuracy
characterizes the system's ability to provide a mean close to the true value when a
sample is measured many times (related to systematic error). We can determine the
precision of a measurement instrument by making repeated measurements of the same
sample and calculating the standard deviation of those measurements. However, we
will not be able to correct any single measurement due to a low precision instrument.
Simply stated, the effects of random uncertainties can be reduced by repeated
measurement, but it is not possible to correct for random errors.
We can determine the accuracy of a measurement instrument by comparing the
experimental mean of a large number…

5. AUTOMOTIVE. The power an
engine produces is called
horsepower. In mathematical
terms, one horsepower is the
power needed to move 550
pounds one foot in one
second, or the power needed
to move 33,000 pounds one
foot in one minute. Power, in
physics, is defined simply as
the rate of doing work. The

If the uncertainties are 0.02mm for length, 0.8mm for the diameters and 0.1mm/s for the velocity, what loss of head will be imminent in this pipe?

Basic Manufacturing Process with 2 Job Types +
Inspection
Time between job arrivals at a machining station is exponentially distributed with mean 4.4 minutes.
There are 2 types of jobs to be processed 30% of which is Type 1 and, 70% are of Type 2. Processing
times are exponentially distributed. Mean processing time for Type 1 is 4.8 minutes, for Type 2 it is
2.5 minutes.
After the job is processed, they go through an inspection process with one single inspector and an
inspection time with triangular distribution (1,2,3.5). Inspector decides whether the part is good
enough, scrap or should be reworked. 80% of the parts produced is good, 10 % is scrap and the rest
needs rework.
Rework is done by the same manufacturing machine. The priority among the parts will be Part1 first,
part2 second and reworks of both type comes later. Rework time is normally distributed with mean 2
minutes and 0,2 std dev.
Simulate the system for one 8-hour day.

to identify the optimum air-fuel ratio for the combustion process in a boiler under
varying conditions of air supply and quality of fuel. The study would involve
design of experiments, data collection and analysis, simulation of the different
variables and validation of the optimum parameters. There is a lot of pressure to
improve the energy efficiency as there is a forecast of fuel price rise in the

You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture
fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates
implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial
weight bearing activities.
Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to
verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into
solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending
test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the
yield stress for the Ti-6Al-4V…
