Assignment # 4

Exercise ContentExercise ContentAssignment 4Review the Behavior Analyst Certification Board Fourth Edition Task List provided in week 1. Under Section ll subsection K Pick 3 tasks and outline how you as a supervisor would provide supervision and support to someone pursuing certification.This assignment will require you to review the task list and research what is involved in each of the tasks you select. In your response you would assume the position that there is an issue needing to be addressed by the supervisor. Your response would be based on what you would recommend to your supervisee to correct the issue.For example: K-01 Provide for ongoing documentation of behavioral services. What kind of documentation do behavior analysts collect and how is this documentation related to client services. The problem would be with documentation. It could be an issue of “canned notes” if a third-party funder is involved or missing information or irrelevant information for the treatment plan …(Canned notes are the same note written over and over each session without change. This is a serious violation with health insurance companies who pay for behavioral services)You have autonomy to decide what the issue is you would provide supervision for. Please be clear and concise with your expression of the issue you have chosen and your supervisory course of action.APA format with citation and references required

Innovation In Sustainable Engineering Design: Hydrogen Fuel Cells.

Hello, I am looking for someone to write an article on Innovation In Sustainable Engineering Design: Hydrogen Fuel Cells. It needs to be at least 1500 words. Coal is not only rich in energy content but also rich in hazardous materials that are harmful to the environment. On the other hand, cleaner fossil fuels including natural gas do produce hazardous fumes that emit into the environment when these are burnt to access their energy content. Most thermal power generation plants use coal as it is the cheapest fuel in most of the regions among all other fossil fuel resources. Underdeveloped countries are also contributing mush to emitting harmful wastes into the environment. There is a need to go for renewable and sustainable energy resources. A hydrogen fuel cell is also a renewable energy resource and it can help underdeveloped countries to cope with the energy demands yet remain in a healthy environment.

A hydrogen fuel cell is a power generation system that utilizes hydrogen and oxygen at electrodes to produce power. The power generated by the hydrogen fuel cell is converted by gathering the free electrons during the reaction between hydrogen and oxygen in the hydrogen fuel cell. A fuel cell has an anode and a cathode. It is obvious that anode has a positive charge and cathode has a negative charge. A single pair of electrodes only generates 0.6 to 0.7 DC volts. In order to achieve a consistent DC current that can be fed to a system, cells are stacked in series and parallel combinations. On the other hand, the current produces by the cells depends on various factors. These factors include the side of the electrodes, the distance between the electrodes, the material of the electrodes, and the amount of air and hydrogen fed into the system (Nice and Strickland, 2015).

Hydrogen is introduced at the anode. while oxygen or air introduced at the cathode terminal of the hydrogen fuel cell. Hydrogen reacts with the anode and gives an electron at the positive terminal. While ionic hydrogen remains in the electrolytic solution. On the other hand, oxygen or air is introduced at the cathode of the&nbsp.cell. Oxygen reacts with the cathode and takes the hydrogen ion from the ionic electrolytic solution and produces steam that is released from the exhaust of the fuel cells. Heat is also released, as the reaction is exothermic. In vehicles, this heat is radiated by circulation water through the walls of fuel cells or through heat sinks attached to the walls of the fuel cells. In general, hydrogen fuel cells ate 40-60% efficient depending on the type of fuel cell technologies.&nbsp.

Discuss Experiment on Optical Fibre Transmission.

Provide a 6 pages analysis while answering the following question: Experiment on Optical Fibre Transmission. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. The results will be viewed on an oscilloscope screen showing the TTL signals generated from the output terminal that will show the outcome of changing the frequency of the signal information. The LED transmitters provide data source encoding for the fiber channel. The implications of this experiment will deliver and demonstrate the resultant effects of varying the intensity of the LED source. The transmission involves light of limited wavelength as low as between 400-700nm. The periodic signal generation is essential for implanting the on-off keying to deploy fiber optical communication.

Any typical optical fiber communication system contains a transmitter, an optic fiber cable, a receiver, and a power supply balance between the source and destination. This project will study how the modulation of the signal frequency will affect the strength of the signal received and viewed on the oscilloscope. The internal of a fiber optic is usually made up of high-quality silica glass meant to refract light information sent from a transmitter to a receiver for decoding.

This wavelength properties of light transmitted are dependent on the fiber optic channel. The speed of the light within the optic fiber medium can be measured by looking at the refractive index of the fiber medium. This is represented in the ratio formula by comparing the speed of light in the material over the speed of light in a vacuum environment (2).

Represent the angles of refraction and incidence at the boundary of the two materials while the n1 and n2 represent the refractive indices of the materials through which the light passes. Decisively, if the light is propagated through a material that has a high refractive index to another that has a low refractive index, then the angle of refraction is usually 90º where the critical angle is.

This is the critical angle of incidence, beyond which if the light intensity exceeds between the two materials, then the light is totally internally reflected. Henceforth, optical fiber communication.&nbsp.
