Dennis was not a helpful professor at all. He writes way too fast on the blackboard, and his writing is often incomprehensible. When asked a question, there's never a clear answer from him. He also tends to throw in a lot of terminology and theory that has not been introduced in lecture yet, confusing students out of their wits. His homework always contains at least one problem about something which has not been taught in class yet. He even recorded students taking the midterm exam without any form of written or verbal consent, to prevent cheating (is this even legal??). The midterm solutions were never comprehensive, would only contain answers without any proper working. The material itself felt like it was being taught in an extremely disorganized fashion, out of order. Several students and faculty alike were surprised at the fact that the concept of Laplace transforms was moved to the end of the course, which makes absolutely no sense given that they are critical for understanding the purpose of the transfer function and frequency response functions. The only saving grace for my interest in the course was the TAs and the Labs that involved using MATLAB. Overall, though I gained a minor interest in further studying the subject on my own, I did not gain an appreciation or flavor for the applications of these concepts in the real world at all through the course alone and was largely clueless. It is my sincere plea to the department to remove this lecturer and only have Dr M'Closkey teach this course.

Great professor, not too sure why there aren't any reviews for him. I took him over summer so the course went by really fast but he honestly made it really manageable. Every lecture was clear and for what others say is one of the hardest undergraduate upper div in mechanical engineering, it was probably my favorite. That isn't to say his class was easy, the midterm and final average were in the mid 70's and low 60's respectively, but he obviously curved so it was nice. But the key to acing his exams is to just really understand the Hw and to do the practice problems he gives you.
Overall, I felt like I learned A LOT from him. If I were to take this class I would definitely take it with him again.
