CONSULTING PROBLEM : CEO RUBBER STAMP
MANAGEMENT CONSULTANTS are often faced with the problem where a CEO/PRESIDENT hires them to enforce his own solutions/ideas, instead of letting them work independently. How does a management consultant deal with this issue ? What are some of the tactics they can adopt. Is such a CEO necessarily bad for a company ?
Polymers
Tetrahydrofuran (THF) is an organic compound with the chemical formula (CH2)4O. THF consists of a four-carbon chain with oxygen atoms at each end. It is a colorless, volatile, water-miscible organic liquid.
Electromagnetic Induction
This document discusses electromagnetic induction and Faraday's law. It explains that magnetic fields have flux lines that run from the North to South pole of a magnet. The flux Φ is calculated as BA sinθ and represents the strength of the magnetic field times the area it passes through. Faraday's law states that an electromotive force (EMF) is induced in a conductor when it passes through a changing magnetic flux. The EMF is directly proportional to the rate of change of flux linkage over time. For a coil of N turns, the EMF induced is equal to -N * (change in flux linkage over time).
Modern engg. materials
The document discusses several materials and their applications including silicon nitride used in rocket thrusters, silicon carbide in ballistic vests, zirconium dioxide in ceramic knives, concrete and plywood used in construction, materials used in hip and bone replacements, SEM images of nickel and nano-cadmium selenide for cancer detection, components of lithium ion batteries including carbon nanotubes and lithium metal, and health effects of carbon black.
Electrostatic harmful effects & control measures
This document discusses electrostatics and static electricity, including its harmful effects and ways to control it. It notes that static charges can build up between a person and their car or other objects, potentially causing sparks or fires. Control measures are suggested to prevent accidents, such as ensuring metallic parts on vehicles are connected to discharge static buildup. The document also explores how much voltage can be produced by static electricity and provides examples of its effects in different situations.

Introduction about Power System Planning in the Presence of Uncertainties
Uncertainties are a key consideration in power system planning. In a regulated environment, a single entity handles generation, transmission, and distribution and faces uncertainties from load forecasting and other input parameters. In a deregulated environment, independent generation, transmission, and distribution companies each aim to maximize profits, introducing new uncertainties as decisions are no longer coordinated. Generation expansion planning faces fuel cost and electricity price uncertainties. Transmission expansion planning uncertainties stem from predicting generation expansions by other market players. Advanced uncertainty calculation methods can help reduce risks and errors in power system planning.

Superposition of AC and DC sources
This document discusses superposition and its use in analyzing circuits with both AC and DC sources. Superposition allows a circuit to be solved by separately analyzing the individual effects of each independent source. The key steps are to solve the circuit for each source alone by shorting or opening the other sources; then combine the individual voltage and current results. Example 1 uses two DC sources in a circuit to demonstrate the technique. Example 2 applies superposition to an RC circuit with both an AC and DC source, calculating and measuring the separate and combined voltage effects across the resistor and capacitor.
Circuit theory 1 finals
The document discusses operational amplifiers (op amps) and their applications in different circuit configurations:
1) An op amp is an electronic device that can perform mathematical operations like addition, subtraction, etc. It has high gain, very high input impedance, and very low output impedance.
2) Common op amp circuit configurations include the inverting amplifier, non-inverting amplifier, summing amplifier, difference amplifier, and instrumentation amplifier.
3) The summing amplifier produces an output voltage that is the weighted sum of its input voltages. The difference amplifier amplifies the difference between its two input voltages and rejects any components that are common to both inputs.
Electromagnetic wave and weapons
1) Electromagnetic warfare is a growing concern and threatens developed countries by interfering with electronics like mobile phones, laptops, and power grids.
2) Electromagnetic waves carry energy, momentum, and angular momentum and can interact with charged particles. They are produced when charged particles are accelerated.
3) Weapons that use electromagnetic pulses (EMPs), such as E-bombs, can potentially paralyze communication systems and damage electronics over large areas. EMP weapons work by using devices like flux compression generators to produce powerful electromagnetic pulses.

3) An integrated load duration curve plots units generated against load demand, obtained from the load duration curve. A mass curve plots accumulated supply or demand over time and is used to determine required storage capacity.
Laser ppt.
Lasers transform light of various frequencies into a chromatic radiation that is coherent, highly intense, highly directional, and highly monochromatic. A laser works by stimulating the emission of photons from excited atoms or molecules in a lasing medium, which causes those photons to stimulate the emission of more photons, leading to an avalanche effect. Nd:YAG lasers use a neodymium-doped yttrium aluminum garnet crystal as the lasing medium, which is pumped by a flashlamp to produce a coherent beam of infrared light. Lasers have applications in industry, medicine, the military, and science due to their unique properties.

This document discusses energy theft detection issues in smart grid advanced metering infrastructure (AMI). It presents an attack tree threat model showing energy theft behaviors in AMI. Currently, meeting demand is not possible and energy theft in distribution cannot be found. The proposed system uses current sensors to detect power theft, sends alerts via GSM, and manages data using Zigbee. This prevents electricity theft and the associated problems of power crisis and load shedding. Hardware includes microcontrollers, sensors, GSM/Zigbee modems, and software is Kiel Compiler and embedded C. A block diagram shows the system components and connections. Future uses include industries, hospitals, and power suppliers to address the estimated $25 billion lost annually to energy theft
Presentation on power
The document discusses different types of power in organizations. It outlines formal power, which is based on one's position, including coercive power using fear/punishment, reward power using incentives, and legitimate power from authority. Personal power comes from expertise and relationships/likability. Greater dependency on someone gives them more power over others. Power comes from controlling something important, scarce, and irreplaceable. The document also discusses influence tactics and sexual harassment as an abuse of power.
Electricity and magnetism
Electricity and magnetism are closely related phenomena. Electricity is the flow of electric charge, commonly electrons, through a conductor. Static electricity refers to the build up of electric charge on an object from electron transfer. Magnetism is produced by electric currents and magnetic materials contain magnetic domains that align in magnetic fields. Electromagnets, electric motors, and generators demonstrate the interconversion between electricity and magnetism through electromagnetic induction.
Superposition theorem
The superposition theorem states that for a linear circuit with multiple independent sources, the total response at any point in the circuit is equal to the sum of the individual responses produced by each independent source acting alone. To determine the individual contribution of each source, all other sources are replaced by their internal impedances. The theorem can be applied to circuits containing resistors, inductors, capacitors, transformers, and independent and dependent sources, as long as the elements have linear responses. The document provides an example using the superposition theorem to calculate the voltage drop and current across a resistor in a circuit with two independent voltage sources.
eddy current brakes
Eddy current brakes work by generating eddy currents in a conductor when it moves through a changing magnetic field. This induces an opposing magnetic field that creates a braking force based on Lenz's law. There are two main types - circular brakes with a disc between electromagnet poles, and linear brakes using a rail and magnetic yoke. Advantages include no wear, adjustable braking, and being lightweight; disadvantages are reduced braking at low speeds and difficulty designing and simulating the system. Applications include high speed trains and roller coasters.
