Choi, J. W., Yim, D. H., & Cho, S. H. (2017). People counting based on an IR-UWB radar sensor. IEEE Sensors Journal, 17(17), 5717-5727. https://ieeexplore.ieee.org/abstract/document/7968432

In this article, Choi , Yim and Cho (2017) focus on the application of the people counting sensor using an impulse radio ultra-wideband radar sensor. As of now, lots of people counting sensor has been research but most of them are using image based. Image based people counting sensor has a disadvantage in terms of privacy. But by using people counting sensor using an impulse radio ultra-wideband (IR-UWB) radar sensor, privacy is not a concern as image of occupants is not used. “This enables people counting even in places where privacy is important, such as hotels or private property” The IR-UWB is a technique that uses an impulse signal with a very short duration in the time domain, which occupies a wideband in the frequency domain. The IR-UWB radar gives out impulse signal to detect people walking by it, this signal is reflected and can be analyzed to determine the number of people walking through. 

 As our project is about implementing people counting sensor in a hotel room, privacy is the main concern. The article provides useful information in showing that people counting sensor can be implemented without intruding the privacy of the occupants.

    Dear Tobi,

    Thank you for the research on the various types of people counting sensor. I believe this information would be useful to support the pros of our proposed solution.

    Regards,
    Bernice

Assignment 1 - Formal Email

  Dear Professor Blackstone, My name is Tobias Hanputra, a student from your effective communication class. I have graduated from Temasek Polytechnic with a diploma in Green building and sustainability back in year 2018. As a child, I spent most of my time playing video games. One of my favorite video games is Minecraft. It is a game where you must acquire the available resources to build creative structures based on your imagination. I have always been curious on what it takes to design and build a building, leading to my interest in Sustainable infrastructure engineering (Building services) course. One of my strength is that I convey a strong sense of confidence in myself at all times. Confidence is one of the key aspects in communication as it allows you to be able to speak concisely with others, allowing the other parties to develop faith and trust in what you said and promised. Despite being confident, I tend to speak in a monotone voice when communicating with others, and d

Task 3: The Importance of communication skills for engineers

“Employers identify communication as one of the basic competencies every graduate should have, asserting that the ability to communicate is valuable for obtaining employment and maintaining successful job performance.” Sherwyn Morreale, Michael Osborn & Judy Pearson, Professors of Communication (2000) Explanation: Being able to communicate effectively are highly essential in order to deliver/receive the correct messages. Hence, employees will be able to communicate well with each other and work towards the same goal.
