On the site's list of courses, there is a "cs" mark for courses in the current semester.
It would be better to let the users see which courses will be given next semester, and which couses where given say in the past two years, so they can plan which and when they take courses. it can be done by adding "semester picker" bar at the top, instead of (or combined with) the "cs" line.

GEARTURBINE PROJECT
Atypical InFlow Thermodynamic Technology Submission
Innovative New ROTARY Turbine Fueled Engine Type

*The Gearturbine comes from the contemporary ecological essential global needs of a efficient power plant fueled motor engine.
-Power thrust by bar (tube); air, sea, land, power generation, work application.
-Have the same simple basic system of the "Aelopilie" Heron´s Steam Turbine device from Alexandria, (10-70 AD) one thousand nine hundred years ago. Because; the circular dynamic motion, with 2/Two Opposites power (polar position) lever, and is feeds from his axis center.

YouTube Video/10.30 min.; Atypical New * GEARTURBINE / Retrodynamic = DextroRPM VS LevoInFlow + Ying Yang Thrust Way Type - Non Waste Looses
http://www.youtube.com/watch?v=0cPo9Lf44TE

*8-X/Y Thermodynamic CYCLE - Way Steps:
1)1-Compression / bigger
2)2-Turbo 1 cold
3)2-Turbo 2 cold
3)2-Turbo 2 cold
4)2-Combustion - circular motion flames / opposites
5)2-Thrust - single turbo & planetary gears / ying yang
6)2-Turbo 2 hot
7)2-Turbo1 hot
8)1-Turbine / bigger

Gearturbine; atypical fueled turbine engine, state of the art. New thermodynamic technology. Turbo-Rotary / Top system.
-With Retrodynamic dextrogiro vs levogiro phenomenon effect. / Rotor-RPM VS InFlow / front to front "Collision-interaction Tpe" - inflow vs blades surface/(gear). Technical unique dynamic motion mode.
-Form-function (flat) wide cilindrical shape / continue kinetic inertia, positive tendence dynamic mass motion. The rotary motor weight is going with the the circular motion power thrust.
-Non-waste parasitic looses system for: cooling, lubrication & combustion.
-Combustion 2Two (Inside dynamic) continue circular flames (like 2two opposite rockets, (at the same axis)).
-2 Two (very) long captive compression inflow propulsion conduits. start at were ends, in perfect shape balance.
-4 Turbos (rotary & translation motion) inside active.
-Mechanical direct 2two planetary gears thurst, inside in a bigger shell, total lever, polar position. (Big torque) (like the Ying Yang simbol concept).
-3 stages of inflow turbo compression before combustion; 1)1-Turbine, 2)2-Turbos 3)2-Turbos.

*The most innovative power plant motor engine project today. Higher efficient % percentage. Next trend wave toward global technological coming change.
