Physical recreation, hormone secretion, immune systems, memory functions, and mood are all related to sufficient and restorative sleep. As biomedical engineers, we would like to quantify this ultimate “sleep quality,” but how can we assess it?
Many engineering schools in the United States provide opportunities for their undergraduate students to gain practical, real-world experience in their chosen disciplines. Cooperative education is a structured method of combining classroom-based education with practical work experience.
It may seem like letting the fox in to guard the henhouse when students are asked to help with the way a class is taught, but it can be valuable to learn directly about student perceptions of course presentations. Having students help direct your course teaching is not such a bad idea.
The origins of convolution and its further and rather complex historical development were dealt with in detail in a previous article. We saw there that it can be traced back to the middle of the 18th century; however, its modern form and use are not more than 50 or 60 years old.
The world is facing a challenge of population growth that carries with it the need to provide all those extra people with sustenance. The human population of the earth currently has an annual growth rate of 1.2%; if that continues, humanity will double in number every 60 years.
A previous “Retrospectroscope” note dealt with spirometry: it described many apparatuses used to measure the volume of inhaled and exhaled air that results from breathing. Such machines, when adequately modified, are also able to measure the rate at which work is produced.
For a long time, sleep researchers have asked why we sleep and what are the physiological and mental needs which require sleep . Today we understand that sleep is important for productivity, health, cognition, and well-being. As a consequence, physical recreation, hormone secretion, immune systems,
Courage is uncommon. It is not the determination to exact revenge or to react with a fear imposed by others, but the ability to persevere on your own despite external events. It is neither denial nor is it unawareness; courage is vigilant and prudent. It is quiet but attentive.
Design projects are a major part of the capstone design course. By focusing on the design process and allowing students to gain hands-on experience in design, they help prepare students for careers in engineering.
Biomedical engineering history is full of hidden treasures, one of whom is Al-Zahrawi, a Muslim surgeon who had a wide reputation in Europe during the Middle Ages. Herein, besides recalling that he was a surgeon, the intent is to spotlight his talent in biomedical engineering.
