A PERT project has 45 activities, 19 of which are on the critical path. The estimated time for the critical path is 120 days. The sum of all activity variances is 64, while the sum of variances along the critical path is 36. The probability that the project can be completed between days 108 and 120 is
a. 0.0227
b. -2.00
c. 0.9773
d. 0.1058
e. 0.4773

Solutions to Practical Unit Commitment Problems with Operational, Power Flow and Environmental Constraints
Presented By:
I. Jacob Raglend and Narayana Prasad Padhy1


Abstract”
In this paper, an algorithm to solve environmental constrained unit commitment problem (UCP) with operational and power flow constraints has been developed to plan an economic and secure generation schedule. Both Economic load dispatch (ELD) and Economic emission dispatch (EED) have been applied to obtai ....etc

Abstract
This seminar describes the main issues facing the development of telerobotics systems connected to the Internet. The initial hurdle relates to the definition and implementation of an appropriate communication protocol for delivering real-time data. Two of the solutions proposed in the literature are briefly summarized. Then examines the issues relevant to control systems in the presence of time delay, with particular reference to telerobotic systems with force feedback. The delay introduced by Internet connections have specific charac ....etc

Power electronics remains an emerging technology. Two important factors in power electronics system are the switching speed of the devices and the total power loss in the system. If the switching speed can be increased ,improvements may be possible i.e. current ripples in an electrical machine or physical size of passive components may be reduced. Increased switching speed may cause additional losses in a power electronics system and increase the system cooling requirement. A common problem is that high-frequency phenomena like proximity eff ....etc

Real and apparent power
 Instantaneous power is the product of instantaneous voltage and current.
 Resistive load.
– instantaneous W is always (+)ve
– W = V x A

 Inductive load
– current is phase shifted
– instantaneous W sometimes (-)ve
– W ¹ V x A
