NETW320 – Converged Networks with Lab Lab #7 Title: CODEC Selection for a WAN Introduction A codec is a device capable of performing encoding and decoding on a digital signal. Each codec provides a different level of speech quality. The reason for this is that codecs use different types of compression techniques in order to require less bandwidth. The more the compression‚ the less bandwidth you will require. However‚ this will ultimately be at the cost of sound quality‚ as high-compression/low-bandwidth

EXPERIMENT 3 MARCET BOILER 1.0. OBJECTIVE • To obtain a relationship between the pressure and temperature of saturated steam‚ in equilibrium with water‚ at all pressure between atmospheric and 10 bar (150 lb/in2). • To compare between calculated values from experiment data to the data obtained from steam table for vfg and hfg . 2.0. THEORY Thermodynamics is defined as a study related to the transfer of heat and work between a system and the surrounding‚ undergoing

potential of a potato Aim Osmosis is the movement of water molecules from a region of high water concentration to a low water concentration through a semi-permeable membrane. Our aim is to investigate the water potential of a potato through osmosis‚ by finding the difference in weight before and after the potato has been set in a solution of water‚ sugar or salt. Trial Method Firstly we collected the equipment. This included a scalpel‚ potato cutter‚ and test tubes. Then we cut the potato using the

The potato’s introduction into Europe proves to be one of the most significant examples of a foreign food crop being able to extensively affect the lives of a an Old World Population. Before the assimilation of the potato crop into the majority of Europe’s agricultural landscape‚ peasant populations constantly faced famines while current food sources provided little nutritional value and were not efficient sources of energy. As Europe adopted the brown tuber‚ people were provided with a far more

my experiment to test the effects of topical chemicals on bacteria living on my hands. In doing this experiment I used hand soap and hand sanitizer on the living bacteria. I followed the procedure for setting up the bacteria culture as listed in the lab manual. I swabbed the bacteria sample from my palm‚ fingers and finger tips. In addition to the two experimental variables‚ I had two separate control quadrants‚ one containing water and the other containing bleach. After completing the bacteria culture

Chapter III METHODOLOGY AND RESEARCH DESIGN The researchers created the system by using Microsoft Excel in order to have Computerized Grading System. The researchers conducted the research thru internet and other feasibility studies in order to gather reliable information base on proposed study. Research Instrument The questionnaires are the main instrument in gathering data for the study. The surveys that we conducted would help the concern teachers to have a better understanding in grading

Module Three: Lab Questions Your first lab link can be found at What is Positive Parenting? A written transcript is also available for this lab. How is positive parenting different from negative parenting? Which do you think is more effective? Why? it’s easy to distinguish negative from positive parenting because parents that use negative parenting skills are usually shouting and yelling and saying a few if you do that again you will get whatever‚ I think positive parenting is more effective

Effect of Sucrose Solution on Osmosis Aim: The aim of the experiment is to show how varying the concentration of sucrose solution affects osmosis by changing different molar solutions of sucrose and water and how it affects the potato. Introduction: In this investigation I will be exploring the effect of varying concentration of sucrose sugar solution on the amount of activity between the solution and the potatoes. Osmosis is the movement of water molecules across a partially
