The features of a heat pump dryer produced by Haier are given as follows, answer these two questions based on the product features.1. drying process (in terms of dryness of clothes) is an open-loop control or closed-loop control (Feedback control). (1 mark)2. Explain why it is open/closed-loop control. (1 mark. Please answer in 50 words, a correct answer with more than 50 words will get a 0.5 mark deduction) ● Heat Pump Condensing Technology.● Number of dry programs 16.● Electronic touch controls.● LED display showing remaining time.● Adjustable dryness level control.● Delay start function.● Sensor drying to prevent over or under drying.

Millennium Software group is assigned to develop a new hardware component for washingmachines to automatically regulate the detergent based on the material and level of dirt in theclothes to be washed. They are asked to develop this component using a new hardwareprogramming platform and this is the first time company use this new technology, Hence, theyhave identified lack of technical knowledge as the major risk item in this project. Further, theyhave identified factors such as training requirement, people skills, company profile andpurchasing as the main causes of the identified risk. Obtaining the expert knowledge, skillassessment methods needed to be considered with respect to the new technology are the majorconcerns under the training requirement. Development experience and soft skills are the factorsthat are needed to consider under the people skills.Page 10 of 1488

Explain the working principle and application of different temperature sensors with neat sketches.

A consumer group asks for volunteers from the general public to take part in a survey of satisfaction with the make and model of washing machine that they have bought, scoring their level of satisfaction from 0 (completely dissatisfied) to 10 (completely satisfied).Question 8Which one of the following is NOT a reasonable statement to make?The machines that suffer the least number of breakdowns will always score highest in the satisfaction surveyThose who volunteer to take part may have different levels of satisfaction with the product compared with those who do not volunteerThose who have bought more expensive machines with many extra features may have different levels of expectation and may be likely to be less satisfied if there are any shortcomings than those who bought cheaper machinesAverage satisfaction levels for particular makes and models of machine that occur infrequently in the sample should be treated with caution
