This highly technical introduction to formal languages in computer science covers all areas of mainstream formal language theory, including such topics as operations on languages, context-sensitive languages, automata, decidability, syntax analysis, derivation languages, and more. Geared toward advanced undergraduates and graduate students, the treatment examines mathematical topics related to mathematical logic, set theory, and linguistics. All subjects are integral to the theory of computation.Numerous worked examples appear throughout the book, and end-of-chapter exercises enable readers to apply theory and methods to real-life problems. Elegant mathematical proofs are provided for almost all theorems.

Keeps my coffee to temperature
Color: Black
it works great at keeping your hot drinks hot, unfortunately you have to remember to turn off once you are needing to step away or leave for the day as it will not turn off on its own until about 8 hours later, drying the coffee or drink and leaving a dry paste in bottom of cup.

it keeps my tea hot for as long as I want it
Color: Black
I really like the cute design of this mug warmer. I bought two so my husband and I can use them at the same time. My larger mugs fit perfectly on it. The four temperature settings, timer, and auto shut-off feature are all very useful. Now I can take my time and truly enjoy my tea.

Love them as a cheap, effective warmer.
Color: Lavender
These really work well and are inexpensive ($20). I bought one for myself and my wife.
Up front they tell you what kind of mugs/cups not to use, so read the information areas. We tried insulated mugs and the heat doesn't get passed the insulation barrier and the outsides get pretty hot to touch.
We now use ceramic mugs and they work very well on these warmers.
There are a number of temperature settings and we found the higher settings to be too hot. You will have to experiment with your own mugs to see what works.
The sensor works well letting the warmer know if a mug is in place and it will shut down after 5 minutes without a mug. Unless your cat comes along early it won't get its feet scorched accidentally.
The automatic timer works as advertised as well.
Four stars because I found that trying to figure out how to actually turn the warmer off was a bit difficult and not so intuitive.
Would definitely recommend these warmers. Hope this review helped.

A very good present for someone special
Color: Black
I got this from a girl you can go ahead and melt scented candles. Just stick the holder down on. It puts out a nice scent cause you 12 hours of warmth to maintain your cup of drink or sent up the room a bit works well.

GREAT AT KEEPING MY COFFEE HOT!!! when i said HOT, I mean HOT!!! *****
Color: Black
So far it's GREAT!!!.
That warmer works great so far
I plugged it, set it at the maximum (185f), put my ceramic cup of hot coffee on it and let it for 5 hours.
when I checked it it was as hotter than when I put it on and the cup was really hot to the touch.
The glass top is very hot so be careful, I touched the marble counter under where the warmer was and it was not even hot (now I'll try with a wooden top desk to see if it will be the same).
So I don't think that you need to set it at the maximum to keep your coffee hot , probably (149f) will be good enough
So far it does exceed my expectation , very easy to use and the price is right.
I'll update if something happens but for now 5 STARS *****
