I need to decide if I want to continue onto a PhD in Electrical Engineering or exit with my MS. I'm not sure what to do, I think academics is kind of cool and I would like to learn more, on the otherhand I sort of want to start working on Real World projects that have some impact and making an...

Hello all, I've recently started working for a big defence company who are willing to send me on a Masters course and it would be most appropriate for me to find a course which focusses on RF/Wireless communications. I have a first class Honours degree in Electronic Systems Engineering from the...

I'm an incoming sophomore majoring in Civil Engineering, and I'm considering a physics minor. The minor doesn't have any math requirements and Civil only requires Calculus I-IV and statistics, but the major in Physics requires a long list of advanced math courses (real and complex analysis as...

That is, for Supernode -1,3 (12V branch) , we do Nodal Analysis and we have (V2-V3)/2 , over the 2 ohm branch. But this current is not included in the Equation 1 in the solution I have attached(Which is my only source to cross check answers/solution right now.) Is the solution wrong? Thanks...

Hello guys, Long story short i am a senior mechanical engineering student (graduating next year). But i do not like my major, at first i did not matter to me what i choose or what i study. i did not know what i like and mechanical engineering seemed a good option to me in terms of good job...

Hi folks. For those in Optical Engineering, detector work or the Optical-Mechanical Engineering field I was curious which society do you use for conferences and research work. Which journals do you tend to look at for research literature. I see SPIE and IEEE are the prominent ones, any...

Hello everyone! This is my first post here, so I'm still figuring everything out. I am a Junior in Highschool, so soon it will be time for me to apply to colleges. Because of my high school, I have direct access to the top private university in Mexico, however, they do not offer Physics as a...

Hello everyone, I am studying at the moment electrical stimulation of nerve fibers. I encountered this image which compares cathodal and anodal stimulation but illustrating the anodal block ocurring with cathode current. But I don't really get the point of the image, could someone clarify it...

These questions keep appearing in my past-papers and yet at no point in the course notes can I find a worked solution. Unfortunately I'm not sure where to start. My initial thoughts were regarding getting an equation using known values but w.r.t. to t and integrating for v, but like I said I...

I’ve been told that physics majors are looked at favorably when applying for entry-level engineering jobs. Is this true? How qualified are they when compared to engineering majors? Are applied physics majors looked at any differently? Do employers care about an undergraduate thesis?

I'm an MS student in Aeronautics & Astronautics who wants to work in industry after I graduate. My undergraduate background is in physics and EE. I wasted a lot of time as an undergrad to health issues and maturing in general and I view myself as lucky to even have a chance to continue my...

I see this question has been asked here before but that was 9 years ago and I’d like to get more up to do opinions. I’m trying to make my final decision and any input would be appreciated. I’ve been accepted into both UofT’s Engineering Science program and Ryerson’s Aerospace Engineering...

Hi, My other post got deleted because it was flagged for spam, but it was just a link to a pdf. So I'm uploading the pdf instead. I am working on a model to predict drag on airfoils in 2D potential flow (e.g. vortex panel methods). Currently, XFOIL uses a semi-empirical wake-momentum-thickness...

Hi. Need help with physics homework. I was able to separate each term and find sigma from the second term and possibly lambda from the first term. Not sure how to approach the third term. (attached attempt at question)

Hey guys! So basically I'm still finding hard to decide what my specialization field should be next year. I'm really torn between a major in Electronics with a minor in Power Systems with some programming additional courses OR major in Power Systems with minor in Electronics. My favourite...

Hi everybody. I'm 40 years old and have been working sales and retail jobs for most of my career and have decided that I'm going to back to school part time with eventually going into mechanical or bio medical engineering. I plan on taking linear algebra and calculus 1 in the fall of 2019 to get...

Homework Statement y(t) = x(1-5t) Homework Equations noneThe Attempt at a Solution well I've never looked at the stability of a signal which has a time scale and shift. My guess is that it is stable as anything I can provide as input will output a bounded signal. Ex: if x(t) is u(t) then...
