Nt1310 Lab Report

The goal of this lab was to expand and centralize our infrastructure by adding a Windows Server 2012 VM and configuring it with a number of key services. Some of the services that we deployed on the Windows 2012 VM had previously been configured on other machines, namely the RHEL VM from Lab 2. We began by installing and configuring the server itself, ensuring that we provided it with ample memory and processing power. Next, we configured DHCP, disabling the DHCP service running on our RHEL VM. We then continued by installing Active Directory and DNS on the Windows 2012 VM, disabling the DNS server running on the RHEL VM in the process. The DNS server on RHEL would later be reactivated as a secondary (slave) server. We then proceeded to set up monitoring for both DHCP and DNS. This monitoring was configured locally on the Windows 2012 VM using the Performance Monitoring utility, and also remotely via OpsView. Finally, we installed Microsoft Baseline Security Analyzer on the Windows VM. This was the first lab where it felt like we

In Part 1 of the lab, a solar cell was created and tested for its capability to conduct electricity. After researching the processes that contribute to the conductive property, it was found that the oxidized substance is the dye, as it donates an excited electron to the titanium oxide. Consequently, titanium oxide is reduced before it donates an electron to the cathode. The electrolyte solution was found to replenish the dye with electrons so it could continue to act as a reducing agent.

The numeric data type 'double' has been populated with the precision as 15 and the scale as 6. It allows null values. The data type, 'date' is populated correctly and allows null value.

The outer membrane in the cyanobacterium cell (Phormidium uncinatum) is the structure that makes the cell gram negative. On the other hand, the characteristic that makes the cell gram positive is the thick peptidoglycan layer.

In this lab we will be studying electric field plotting through the use of various apparatus. The equipment we will be using includes a digital voltmeter, voltage probes, carbonized acetate sheets, battery, and other tools of measurement. The goal of the lab is for us is to be able to plot lines for charge distributions and to create electric field lines by providing an electric current through carbonized sheets. Once we have completed constructing the electric field lines for the plate charge distribution, we will continue to calculate for the electric field (E = Vx) and begin to plot for the dipole charge distribution. When we have collected all the data needed, we then will finish calculating for all the remaining variables and complete the rest of the lab report.

For each point, you would add 7 to the x coordinate and then take away 1 from the y-coordinate.

In Lab 8, the time constant of resistance-capacitance was measured in order to determine the charge of a capacitor. This experiment was conducted by setting building a circuit that connects the voltmeter across the resistor. The voltmeter was then connected across the capacitor. The above procedure was conducted several times using different voltages. Afterwards, the results were calculated and tabulated. The data obtained from the lab were the theoretical Tau for 5V, 4V and 3V. In this experiment, the calculated voltage was also determined. The theoretical and the calculated values were then compared and evaluated by determining their percentage errors. For example, in the 5V, the theoretical value was 1.23V; calculated value was 1.434 with a percentage error of 16.6 %( for voltmeter across capacitor).

Usage of mobile phone to connect to social media is growing all over the world. Nowadays smartphones come with numerous health-consciousness apps, too. This study is to find out users’ preference between networking and health while choosing mobile phone.

Since proton takes part in the oxidation of MTX, the pH value of solution will greatly influence the Ipa [45]. The effects of stripping pH value of the PBS buffer solution on the electrochemical performance of MTX were also tested with the pH varying from 3.0 to 9.0 using 0.05 M PBS buffer and theresults were depicted in Fig. 9.The results showed a maximum of Ipa when the buffer solution pH was 4.0 (Fig. 9). Therefore, in subsequent experiments, the stripping was carried out in 0.05 mol L-1 phosphate buffer with pH

Distilled water was used to dilute the solutions used in the cells, a hot plate was used to increase the temperature, sand paper to sand the metals, filter paper to act as the salt bridge, thermometer, and a voltmeter to measure the voltage. For part 1 of the experiment a total of 6 beakers are needed to hold the solutions to conduct the first test. For each metal two beakers are filled with 30mL of the .1M of solution for that metal using the graduated cylinder. Each metal solution is then paired with another metal solution such as Zinc with Copper and Zinc with Iron. Use the filter paper and soak it in the KNO3 solution to create a salt bridge, repeat this three times for each pair of metal solutions. Proceed to sand the metals then place them into their respective solutions and use a voltmeter to measure the voltage. Make sure to place the right clamps on the anode and cathode you will know if it is wrong because the voltage will be negative. Repeat this step for each of the pair of solutions then proceed onto part 2. In part 2 of the experiment zinc and copper solutions were used. Take two 50mL beakers and fill one with 30mL of zinc solution and the other with 30mL of the copper solution and connect them with filter paper that was soaked in KNO3. Sand the metal pieces for copper and zinc then place them in their respective solutions then proceeding to connect the voltmeter to

In these entire applications polymer played important but supportive role and the main work of electrical conduction was done by metals. However attempts were made to impart electrical conductivity to polymer films and fibers by several different methods, with the aim of developing flexible conductive materials.

PZT is mostly used in thin film formations and is known for its high dielectric constant, meaning that PZT can store a large amount of electric charge in an electric field. This dielectric constant depends on the film’s composition, with the highest value measured around the morphotropic phase boundary. The morphotropic phase boundary is where a ferroelectric material transitions from its tetragonal and rhombohedral phases, which for PZT is around an atomic ratio of 1.00 Pb:0.52 Zr:0.48 Ti (Chen et al., 1992). PZT is made via a number of processes where a film of the desired composition is deposited on a substrate and annealed to crystallize. The film deposition can take place in different ways, including sol-gel spin coating, molecular beam epitaxy, chemical vapor deposition, pulsed laser deposition and sputtering (Chang, 1999). While these factors have an impact on the final properties of the PZT, the final annealing determines the majority of the properties.

This practical involved investigating the behaviour of equipotential and electric field lines between two electrodes (which represented the a parallel plate capacitor). Furthermore the effect of adding a conductor and an insulator between the two electrodes was explored to determine the electric potential produced from these configurations.

methodology based on the work of Brocklehurst [94] has been attempted to assess the ability of the reconstruction algorithm to calculate conductivity profiles

However, this equivalent circuit could no longer provide a satisfactory fitting result with the elapse of time. As the electrolyte solution, water and oxygen gradually penetrated through the coating and even arrived at the coating/substrate interface, a different equivalent circuit Model b taking account of the appearance of electrochemical corrosion reaction at the metal interface was used, as shown in Fig. 7b. Specifically, the Cdl in parallel with the Rct in model b represents the Faradic reaction. In terms of the coating system where diffusion impedance appeared, Model c (Fig. 7c) was adopted to fit the impedance data. The Warburg diffusion behavior attributed to the deterioration of the coating protection and the continual diffusion in the coating system. Based on these fitting models, Rc and Cc of different coatings at a function of immersion time are shown in Fig. 8. The Rc gradually dropped with immersion time, which is another evident sign for the invalidated resistance against corrosive species transfer through the pores of coating. Besides, the Cc increased with prolonging immersion time because of the higher local dielectric constant of water than that of the polymer. PBA/α-ZrP-5% and PBA/α-ZrP-10% coatings exhibited higher Rc values, suggesting that the incorporation of >5 wt% α-ZrP in PBA matrix effectively decreased the corrosion reactions on the coated metal surface. Further, the Cc value of nancomposite coatings is relatively lower compared
