...Technology is ever changing in today’s world. Most people are accustomed to the traditional fixed line LAN, but there are others who are always on the go and would like to explore the possibility of cellular networks. The purpose of this paper is to compare and contrast several attributes of purely fixed line networks vs. having a purely cellular network. Fixed line networks have been and will continue to be a huge industry because the major players provide the backbone. For this reason alone, the company should not expect to pay outrageous prices for equipment. From a security standpoint, fixed line networks are less susceptible to wire sniffing attacks and more secure than cellular networks due to the fact that the hacker would have to gain access to the fixed line network rather than simply intercepting the transmission from a cellular network. While fixed line networks are considered the norm for most companies, they do have limitations. A company which adopts a purely fixed line network will not have the capability to send or receive data unless the user is physically inside the company. This would prove to be a major drawback to companies who have employees who travel to other cities to attend meetings, seminars, etc. Cellular networks are relatively new and are still developing. While employers can expect increased productivity due to employees being able to send and receive data at any time, one important drawback is the fact that the employees need to be in...

...In order to get the future value on an investment one has to use the formula A=P(1+i)^n . Where A is the future value, P is the present value, R is the annual rate, M is the number of compounding periods per year, I is the rate per compounding period, and N is the total number of compounding periods. For Example: If an investment of $100 were made in 1776, and if it earned 3% compounded quarterly how much would it be worth in 2026? After one determines that 100 is the present value, one has to divide the interest rate by four. In addition, one has to multiply the years that the money was invested times four. That is to say that since the interest is compounded quarterly, 3% is going to be multiplied by your balance four times every year. The quotient of 0.03/4=.0075....

...NT1310 Codi Roebuck Unit 10 Lab 1 01/04/2016 Professor: Ronald j. wojcik Fiber optics for diagnostics and troubleshooting are used in varying capacities to test, measure, analyze, transmit, distribute, and/or simulate an optical signal with which the technician can perform procedures and processes associated with maintenance, problem solving, and calibration of equipment and/or networks. Normally in these applications, fiber optic products are used to create loop tests or transmit signals from point-to-point (either single-point to single-point, or single-point to multiple-points). For loop testing, commonly referred to as loopback testing, a signal is sent from a piece of equipment through a loopback or cable and returned to the source, simulating a complete network connection. This type of test allows technicians to perform function tests and internal diagnostic processes without the equipment being physically tied to an active network. This type of setup provides technicians with the advantage of easily isolating individual components for faster, more comprehensive analysis. With signal transmission applications, technicians generally use cables (multiple types for different applications) to connect one or more pieces of...

...Unit 7 Lab 1 New Building Safety Plan In my safety plan the first things that I’m going to cover are the PPE for working on a construction site where a new building is being placed. First you’re going to need a hard hat so that when anything falls from above, it keeps your brains where they belong like in your head. Second steel toed shoes or boots, preferably boot for a little extra ankle support. But the steel toes to protect your feet from anything being dropped or lowered in case your foot gets in the way. Safety goggles, pretty self-explanatory on this one, just need to keep things out of your eyes! Long pants (blue jeans) protect your legs from different object that could hurt your skin but with pants on you might just get a bruise. Next on the list gloves are always a good idea to wear so that you don’t rip your hands up while you’re working! A water cooler is a must in this situation because it’s going to be hot out and hydration is key to survival! There will also be no running on the job site. Hurry to quickly can cause more accidents than any amount of production you’re getting for running that thirty foot. Only work on the parts of the job that you know, if someone ask for help go ahead and give them a hand but if you’re a plumber then just let the electrician handle his own job. Back to PPE for a sec a back brace would be a good idea to wear also. Once you have a back injury it will be a problem for the rest of your life in most cases. In case of an emergency...

...A GPR is made up of three core components, control unit, antenna, and the power supply. The control unit is what contains the electronics which trigger the energy pulses to the antenna that sends it into the ground. The GSSI SIR 20, which was used in this lab, has a laptop with software loaded on it already which processes and interprets the data. The antenna is what receives the electrical pulse from the control unit and transmits it into the ground. The frequency is a huge factor in the depth penetration. The frequency that used was 200 MHz which is right between the high and low pass filter allowing a the signal to go deeper. The time interval for collecting this data was 400 ns with 20 traces per meter. In this amount of time and traces per meter, 12 transecs were collected. The AGC was used to amplify the GPR lines getting better data. The data from the GPR was then brought back to the lab and the lines and sections were examined to figure out the GPR facies. The equipment used for coring was an auger core....

...Amazon With amazon services you choose a service plan based upon a completely virtual environment. Using a preconfigured AMI (amazon machine image) or creating your own with its own set of network permissions and protocols. This also chooses instance types you may want. Multiple services using AMI and with that utilize static endpoints or attach persistent block storage to said instances. The resources you use is what you will pay for out of the total plan you have chosen based upon time or data transfer. Amazon also has an elastic block store based service with offers persistent storage for amazon EC2 instances. EC2 is a program which you decide a system to boot into it so it can be stopped and restarted with the whim of the client. With this the EBS volumes can be measured and observed by the client. EC2 also provides multiple locations. This is based mainly open regions and available zones. Elastic or dynamic IP addresses are available for wireless and mobile devices that will use these cloud services. Virtual private could is a thing all its own that will create logically isolated sections of the amazon web services which you can launch within your AWS resources to create a virtual network which you can also select your own section of IP addresses, subnets, and configuration of your route tables, networks and gateways. Within these services a Virtual private network (VPN). Amazon cloud watch is a service that monitors your data. This gives stats, graphs, and alarms when...

...the attached cable through an inaccessible space. This allows you to pull the cable and protect the fiber ends from damage. PULL BOX – A pull box is usually installed after a long straight run or every time the set of turns totals 180 degrees or more. The pull box is used to create a intermediate opening for the pulling cable to reduce the length of cable being pulled through the conduit or to reduce the number of turns the cable is being pulled through at a given time. It is important to keep in mind the bend radius of the cable when using a pull box. SPLICE ENCLOSURES – Splice enclosures can take many forms depending on their location and application. Splice enclosures can be typically place in one of the two following categories. 1. Radial Splice Enclosures – radial splice enclosures have cables enter and exit the enclosure on the same side. 2. Axial Splice Enclosures – Axial splice enclosures have cables enter and exit on opposite ends of the enclosure. Enclosures designed for outdoor use are environmentally sealed. Typically all enclosures will include: * A strain relief system that ensures the...

...where C_gP^* is the gate capacitor per unit width of Mp2, f_cis the carrier frequency (f_c=13.56 MHz), D_effis the effective duty cycle, and W_p is the width of Mp2. Additionally, the optimal size ration for the NMOS and PMOS transistors (Mn1, Mn2, Mp1 and Mp2) has been proven in [2], and van be formed as: (W_p/W_n )=√((K_n (V_REC-V_(ThN) ))/(K_p (V_REC-|V_(ThP) |) )) (3.5) where K_n=μ_n C_ox and K_p=μ_p C_ox, are the transconductances of the NMOS and PMOS, respectively. The main rectifying transistors should have an optimal sizes to minimize the power dissipation depending on f_c and R_L because large transistors will decrease the R_on loss, but it will increase the switching loss. More over large transistors will make an impact on the speed of the comparator due to the gate capacitance [2]. 3.3 The Comparator...

...Graph 1 as shown above describes the relationship of length and tension from the data gathered from the experiment. In this graph, the two variables are increasing in each point, thus it can be generalized that the length of the string is directly proportional to the tension of the string Graph 2 as shown above describes the relationship of length and varying linear densities of the strings from the data gathered from the experiment. In this graph, the two variables are not equal in the change that is happening on them in each point, whereas the linear density of the string increases the length of the string decreases. Thus it can be generalized that the length of the string is indirectly proportional to the linear density of the string. The experiment conducted is an example of a transverse wave. Waves are classified into two types, longitudinal and transverse wave. Transverse wave is defined as a moving wave which is consisted of oscillations, which occurs perpendicularly to the direction of the energy transfer. This type of wave has a sinusoidal wave pattern which is visually represented by a standing wave as a result of the interference incident and reflect waves. The guitar strings used in this experiment showed...
