CPM - Critical Path Method

Definition:

In CPM activities are shown as a network of precedence relationships using activity-on-node network construction
Single estimate of activity time
Deterministic activity times


USED IN : Production management - for the jobs of repetitive in nature where the activity time estimates can be predicted with considerable certainty due to the existence of past experience.

The high-tech industry has spent decades creating computer systems with ever mounting degrees of complexity to solve a wide variety of business problems. Ironically, complexity itself has become part of the problem. As networks and distributed systems grow and change, they can become increasingly hampered by system deployment failures, hardware and software issues, not to mention human error. Such scenarios in turn require further human intervention to enhance the performance and capacity of IT components. This drives up the overa ....etc

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

Smart Cameras in Embedded Systems

Introduction
A smart camera performs real-time analysis to recognize scenic elements. Smart cameras are useful in a variety of scenarios: surveillance, medicine, etc.We have built a real-time system for recognizing gestures. Our smart camera uses novel algorithms to recognize gestures based on low-level analysis of body parts as well as hidden Markov models for the moves that comprise the gestures. These algorithms run on a Trimedia processor. Our system can reco ....etc

The Ping of Death uses a ping system utility to create an IP packet that exceeds the maximum 65,536 bytes of data allowed by the IP specification. The oversize packet is then sent to an unsuspecting system. Systems may crash, hang, or reboot when they receive such a maliciously crafted packet. This attack is not new, and all OS vendors have fixes in place to handle the oversize packets.

Introduction
PERT Project Evaluation and Review Technique is a network model that allows for randomness in activity completion times. PERT was developed in 1958 by the SPECIAL PROJECT OFFICE of U. S. Navy for Polaris Missile Program. It has the potential to reduce both the time and cost required to complete a project.
CPM Critical Project Method is a deterministic method that uses a fixed time estima ....etc
