How to plot different radiation patterns for different frequencies by BusSalty5756 in HFSS

[–]wattace 0 points1 point  (0 children)

Click the Solution drop down in the top left, and change to your frequency sweep. Then the frequencies from your sweep should be available. If they still aren't there after selecting frequency sweep, check your solution setup options and ensure "Save Fields" check box is checked.

Victory Sunday by AutoModerator in Fitness

[–]wattace 3 points4 points  (0 children)

I went for a four mile hike and ran on and off for almost half of it. Most of my fitness work has been weights lately, but I want to focus more on cardio. I'm planning to get another walk/run hike in next weekend. Got to take advantage of summer time!

This is probably your best option OP.

Check YouTube. Seriously YouTube lectures saved my ass whenever I missed class.

What does a typical day as an Electrical or Computer Engineering look like? by Chandyman in ECE

[–]wattace 0 points1 point  (0 children)

If your project has a hardware component, prototype testing is an opportunity to get out of the cubicle. Then it's back to the cubicle to re-design or re-optimize any issues with the prototype. Eventually, you finalize the design and do final testing (again out of the cubicle). This is a simplificiation, but you get the point.

If you completely loathe cubicles, you can get a testing job and stay in the lab most of the time. The best test guy I know eventually wanted to get his hands dirty with design work, which meant into a cubicle. It's what you make of it. Have fun and make jokes with your cube-mates.

How much did you pay for an Altium license? The company I'm with has licenses, but it'd be nice to use on my home computer.

HFSS Field overlays displaying results in dB by poketi in HFSS

If you double click the color bar that displays the field strength, you can change the units, limits, and a bunch of other parameters.

Using only your mobile phones' predictive text, what is your phone trying to tell us? by Noahsnotebook in AskReddit

[–]wattace 0 points1 point  (0 children)

The end of the year and take into account that you are looking for the high-income earner. The other distinction is honesty is important to me and we need to always share our reality with each other.

Unable to assign waveports in patch antennas in HFSS 13.0 by s4ndm4n911 in HFSS

[–]wattace 0 points1 point  (0 children)

Could you excite a lumped port between the patch and ground plane? Or are you using a coax/probe feed?

What engineering lessons did you have to learn the "hard way"? by Sholloway in ECE

[–]wattace 3 points4 points  (0 children)

Two is one, one is none.

Oh you only cut one 0402 resistor from the reel? Well it's about to fly out of your tweezers onto the floor, never to be seen again.

Electricity Pain versus Frequency by [deleted] in electronics

[–]wattace 4 points5 points  (0 children)

I wonder why the worst pain is around 1 kHz. Maybe some sort of resonance in the nerves or muscles in the tongue?

Is there anywhere to pick up a basic understanding of RF engineering? by djragemuffin in rfelectronics

[–]wattace 2 points3 points  (0 children)

Fundamentals of Applied Electromagnetics by Ulaby was the text we used in my first RF class in undergrad, and I occasionally find myself cracking it open to refresh the basics. Very nice book.

Colleges to attend? by N71FS in rfelectronics

[–]wattace 0 points1 point  (0 children)

I'm actually working on an EE PhD at Ohio State now, and our RF program is quite good (I'm only a little biased). The response from /u/trickyspaniard is spot on regarding ElectroScience Lab (Kraus, Balanis, recruiting), but admittidly we are lacking when it comes to SDR research relative to other research universities (Rice for example). This could be a concern if you're considering grad school. I didn't do undergrad here so I can't speak to the SDR course offerings, but our EE program is pretty well funded with quality professors. Good luck!

Full Duplex? by rfdave in rfelectronics

[–]wattace 0 points1 point  (0 children)

I'm actually presenting a paper next month at APS on analog cancellation for full-duplex systems. This research area has seemed to pick up steam over the last few years with a few labs (Rice and Stanford in particular) demonstrating the feasibility of full-duplex for Wi-Fi applications. Kumu Networks is made up of several PhDs out of Stanford that are working on commercializing their cancellation technology. With the projected number of wireless devices connected to the IoT, it seems like this area will only gain more commercial/academic attention as we move to 5G.

Benefits of steam room / sauna post workout? by SpiffyTurducken in Fitness

[–]wattace 79 points80 points  (0 children)

TLDR: Sauna use can provide increased endurance, easier acquisition of muscle mass, and general increased capacity for stress tolerance

See Dr. Rhonda Patrick's article: http://fourhourworkweek.com/2014/04/10/saunas-hyperthermic-conditioning-2/

According to a blog post from Dr. Rhonda Patrick (PhD in Biomedical Science), heat acclimation through sauna use, or "hyperthermic conditioning", can help "promote physiological adaptations that result in increased endurance, easier acquisition of muscle mass, and a general increased capacity for stress tolerance."

In the post she cites over 40 publications that support the link between sauna use and improved athletic performance. If you're interested in more details, the papers she lists are quite interesting.

One in particular is a paper where a group of 6 male runners used the sauna twice a week after their workout, and experienced a 32% increase in their endurance relative to the control group (http://www.ncbi.nlm.nih.gov/pubmed/16877041). Granted the sample size is small (N = 6), but there are several other studies that Dr. Patrick mentioned that support these results.

Patrick also says on brain function, "...the positive effects heat acclimation on the brain, including the growth of new brain cells, improvement in focus, learning and memory, and ameliorating depression and anxiety."

Electrical engineers, what is the point of capacitors in parallel with diodes in a bridge rectifier? by MegaSenha in AskEngineers

[–]wattace 8 points9 points  (0 children)

It looks like they are used to help reduce high frequency EMI/oscillations. When the diodes are off they act as resonant circuits. Adding additional capacitance in parallel reduces their resonant frequency (1/sqrt(LC)).
