Tips To Pass The Electrical Engineer Certification

By | Engineering | No Comments

Preparation is the key for passing an exam. That also includes the FE, Fundamentals of Engineering exam, as this is the one required for a person to become an electrical engineer or another type of engineer. It is a long exam that takes 8 hours to complete. That is cut into two sessions, one morning and one afternoon. There are tips to pass the electrical engineer certification and those combined with great study practices will ensure that a future engineer passes with flying colors.

An engineering degree is one of the best tips to pass the electrical engineer certification, as it is required before the exam. That includes an associate’s, bachelors and master’s degree that can be achieved while in college before the exam is taken. In addition, the exam can be introduced during a student’s last year in college. Another tip is studying and the sooner, the better. Reference materials are a great testing aide as they can provide sample questions to prepare someone for the exam. These are available in book form and even CD for those who would rather listen to the materials instead of reading them.

Studying is the only way to ensure that the exam will not have any surprises on it. This tip to pass the electrical engineer certification is more accessible if you set up a study schedule so that every part of the engineering world can be worked on and refreshed in your mind. Even if you think you know it and are quite confident it never hurts to look over or listen to the material one more time. Being an electrical engineer is all about learning and adapting new practices to technology and the first step is the exam that certifies you as an engineer. These are just a few tips to pass the electrical engineer certification, you will learn more as you study.

Monitoring And Characterisation System

By | Engineering | No Comments

We have designed an in-situ optical emission spectrometer with an optical fiber probe. This system consists of four optical fiber connected spectrometers for convenient and flexible on-line monitoring. The spectrometers cover a wavelength range 200 to 1100 nm, with resolution of 0.45 to 0.55 nm. It contains wavelength and intensity calibration kits, data acquisition and control software, as well as an interface with AEC’s expert software systems.

The system is capable of:

  • Calibration based on extensive database
  • Detection of processes degradation to comprehend the drift in the processes due to time dependent environmental effects
  • Fault and impurity trace identification
  • Quantitative multi-element identification and
  • Real-time decision making

This system has been demonstrated in analysis of semiconductor etching process in a reactor measured by optical emission spectrometer, (K. T. Lu and Dennis Baba, in Abstract of Pittcon ’98, #1015, New Orleans, LA, March 1-5, 1998). The system is capable of quantitative determination of the spectral degradation due to the time dependent drift in the reactor. The whole process, including calibration, analysis and identification, takes less than two minutes. Therefore, the software system can be used for real-time application.

This system has wide range of applications including nanomaterial processing, environmental characterization, laser technology, astrophysics, plasma diagnostics, laboratory analytic chemistry, energy research, IC, and polymer material processing.

Our products and services have been demonstrated successfully in the following areas of application: publication and demonstration and material processing.

Debris Chute
Construction sites are always prone to accidents, dirt and unsafe working conditions. During construction debris is generated. Disposal of this construction waste is nightmare for Project Engineers. Lots of accidents happen due to this and most of them are fatal.

Human life is invaluable and occurrence of these accidents may lead to huge financial, legal liabilities and site schedule can go haywire. This loss is immense.

Some Of This Problems Associated With Unsafe Disposal Of Debris Are As Follows.

Accidents, mostly fatal accidents.
Huge financial and legal liabilities.
Unsafe working environment for workmen, staff and visitors.
Deviation from latest OSHAS and ISO 14000 norms.
High dust and noise level.
More manpower for debris disposal.

Garbage Chute | FAQ’s

What is a Refuse/ Garbage Disposal chute? How is its existence to the Building Industry?
A Refuse Chute or Garbage Chute is used for safe and easy disposal of Garbage from each floor. It is convenient to use and provided as an amenity to most residential buildings today.

What is Centralized Garbage collection?
A Centralized Collection enables collecting Garbage from each flat on every floor through a Disposal Chute into a collection Chamber/Trolley at the ground level. Users need not use the passenger lift, or the stairway.

How does a Garbage Chute work?
Users have to open the intake door and simply deposit the Garbagein in the self closing Intake Doors. The Garbage moves along the Chute and collects in a trolley at the ground level. The Intake Doors are amicably made to recive a particular volume of disposal to avoid damage and choke-up.

How hygienic is a Garbage Chute?

All Intake Doors are sealed with a rubber lining to prevent insects and foul smell. The chute has an Air-Vent at the topmost floor, which will dispel gases from the chute. The chutes also come with ‘Sprinklers’ which will wash the chute and keep it clean.
For example:

The Liquid Deodorant Sanitizing unit will spray deodorant into the shaft through an electronic control unit supplied with the chute.
An electrical or mechanical blower is also provided to emit the gases from the shaft.
An Electro / Mechanical cleaning system using a heavy bristled brush also cleans the chute. With the above system the chute and it surroundings can be kept hygienic at all times.

Is it environment friendly?
Garbage Chutes enable easy disposal of waste. This waste is collected and segregated in a trolley at the ground level, which ensures hygienic disposal.

Laser Remote Sensing

By | Engineering | No Comments

Laser Remote Sensing (LRS) combines the advantages of laser’s ability to excite atoms and molecules and radar’s ability for remote sensing. LRS relies on the “fingerprints” induced by laser excitation, absorption and ablation of the elements or chemicals for detection. There are many types of LRS, e.g. Differential Absorption LIDAR (DIAL), Laser Induced Fluorescence (LIF), and Laser Induced Breakdown Spectroscopy (LIBS) and etc. LRS has found its application in environmental characterization, global atmospherical monitoring, geological survey, oceanographic mapping, and potential in Homeland security.

AEC scientists will help users to identify and design laser and sensor technology as well as computational softwares for their application.

AEC has successfully interfaced and integrated an array of laser and sensors which include:

  • UV/VIS spectrometer (Varian),
  • Laser induced optogalvanic calibration unit (Laser Analytic, Inc.),
  • FTIR (NASA -remote sensor),
  • Laser induced fluorescence (LIF) detector (AEC),
  • Laser induced emission detector (AEC),
  • Laser induced breakdown (LIB) spectrometer (LANL) and optical fiber based optical emission spectrometer (Chromex, Inc.)
  • Hand-held optical fiber optics spectrometer (Ocean Optics).

You are welcome to download a presentation on Laser Remote Sensing and three publications:

  1. American Env. 97, Analysis of matrix effect of RCRA metal elements in soil measured by an in situ laser-induced breakdown spectrometer
  2. American Env. 98, Analysis of solid material by laser-induced plasmas
  3. Physics Essay, 2000, Cooperative and Relaxation Mechanisms in Laser-induced Plasma

Laser Remote Sensing has proven benefits in the fields of machining, manufacturing and general engineering. Our products and services have been demonstrated successfully in the following areas of application: publication and demonstration.
