Smart phone app

Written by Seungyeon Lee


There are countless technology/systems that engineers have developed. One of them is a cancer-detecting smartphone app. Below is the photo of the cancer-detecting smartphone app.


Researchers from Washington State University have used prism, ELISA plate to make a smartphone app that would detect cancer. It is said that it could detect cancer with 99% of accuracy. 

How it works is really fantastic! There are 96 micro prism array and a 3D printed cradle which holds a phone with a camera. Then, the diagnostician uses the rig to take samples from the patient. Those samples will be put in the assay plate and the light from the camera will be shining the sample through the prism and the diagnostician would use an app to analyze the light from each patient's well in the ELISA plate by its color, and the color of the ELISA would tell the result. 

It sounds really cool and I would love to try it too. It is also cool that a smartphone app could be made to help a human's health. I think engineers should devise more ideas that would help human life like what this smartphone app did.

Autonomous Vehicles


Written by: Adam Tarrant

          Modern technology is ever changing in today’s world. Although there are very little companies using these vehicles, the world anticipates autonomous driving cars to be sold to the public in the future. It’s no surprise people are excited about this invention, easing the stress of driving, especially in heavy travelled areas. 

          On the other hand, there may be some downfalls of this hardly researched technology. My first question is what will happen if the car malfunctions? Can the rider manually take over the vehicle? There are many cases in which technology has malfunctioned, while it was promised it wouldn’t have. This is a small issue in my mind because we see thousands of human-error motor vehicle accidents every day. This self-driving car very well might cut down on these accidents. 
          Also, if the cars were to be used in cities with high pedestrian levels, will the cars be able to avoid people that are walking across the street or will the world need to create structures that will keep the pedestrians and cars separate? Would we have to create fenced sidewalks? Raised roadways? These are things that not everyone is thinking about that could change our present roads and structures. 

          Engineers will be more needed than ever, struggling to keep up with the ever-changing environment we see today.



Mythbusters

By Callaghan TysonMayer

Purdue engineering majors recently wrote a journal article about common myths about engineering students. The authors identified 7 myths they have heard about themselves, as engineering majors and broke them down as to why they are inaccurate.

  1. The first, is that engineering students all love math and science. This is not true because a lot of future engineers just like the idea of hands-on applications that have a set outcome. 
  2. Engineers sit at a computer all day. This is extremely false, because most of the work engineers do is in the field, working hands-on with team members on real physical projects. 
  3. Engineers aren't very creative. If this were true, it would make everything much more difficult because engineers have to come up with different solutions to problems in the field. Often, it is an engineers job to create a completely new way of doing something, and to recreate the process for better efficiency. 
  4. Engineers don't have good communication skills. This was a focus of one of the lectures we had for our EGR100 class this semester. Professor Morgan spent 2 weeks explaining the importance of communication in our field because a lot of what engineers do is done in teams, so you have to be able to communicate with your team members.
  5. Engineers only work on significant projects. This isn't completely accurate because there are instances where engineers are checking up on codes and making sure everything is done correctly, which is a significant job, but what is insignificant?
  6. Engineers don't have fun or diverse interests. In my opinion, there are so many different branches within the field and they all vary by a lot. Everyone has different interests with different ideas of fun.
  7. Women aren't engineers. This isn't very hard to disprove, since the field is actually almost evenly gendered now and 3 of the 4 engineers that run this blog are women. 

Chemical Engineering Safety Measures

written by Yiran Li

Chemical industry is a diverse industry and its products are omnipresent. The modern technology in developing these tailor made chemicals has been quite successful. As with any industry setting, safety is a major concern for the firm to run properly. The major hazards encountered in the operation of the plant in the chemical industries are toxic and corrosive chemicals release, fires, explosions, falls and faulty mechanised equipments. (NPTEL) Also, the design engineer must be aware of these hazards and must make every attempt to present a design which needs to be protective of the environment and of human health. Environmental issues must be considered not only within the context of chemical production but also during other stages of a chemical's life cycle, such as transportation, use by customers, recycling activities, and ultimate disposal.

Chemical engineers need to analysis potential hazards and take corrective measures to improve the safety of the process. The entire approach can be summarized as follows:

1.  Identify the hazards:“ what can possibly go wrong ”
2.  Evaluate the hazards:“ what are all the causes and how bad it can be ”
3.  Control the hazards:“ what should be done about it ”


Even though chemical industries take major precautions in ensuring the safety of their employees, the chemical processes that chemical engineers design and implement are not always safe. Occasionally, unexpected releases of toxic, reactive, and/or flammable liquids and gases ensue. A substantial amount of chemical engineering firms work together with the non-profit membership organization like CCPS, AIChE, or other private and government programs.
