...PERSONAL NARRATIVE 1 When taking a look at how my life has changed over the past five years I can truly and honestly say that I would never have expected the things that have happened. Back in June 2007 I was separated from my husband and moved into my own apartment. I was in the United States Navy for six and a half years at that time. My divorce was finalized in January 2008 and I deployed to Afghanistan in March 2008, for eight months. After coming home from a long deployment, I had orders to move to Lemoore, California. This area is nothing but farm lands and I did not like that at all. I was born and raised in Southern California and enjoyed the fast-paced life that I was living. It is amazing how things have changed. In July 2011 I was honorably discharged from the United States Navy and I moved back in with my mother and two younger sister. Growing up we lived in a condo in Diamond Bar, California, but that all changed over time. The same time that I got out of the military, myself, my sisters and my mother had to move out of our condo and into a two bedroom apartment. Talk about a huge change in life. This move has not been easy for any of us. There is no privacy and we all have to share the living space. I share a bed with my middle sister and my mother shares a bed with my youngest sister. I never thought that I would be unemployed for this long, but it has been over a year since I got discharged. It seems like nobody is hiring right now...

...Few good man Time from time you may hear stories of abuse by the military justice "system". There are multiple destroyed and financially devastated families out there suffering heartbreak and loss at the hands of an uncaring, unfeeling and unjust process which makes a mockery of our Bill of Rights. Military justice for the majority is prefabricated according to the wishes of the local Commander, and the "trial" or "court-martial" is tantamount to a pre-ordained verdict of GUILTY. How could any court proceeding be considered fair when the "convening authority," by right of title, is given the power to select the judge, the jury and defense and prosecution attorneys? It may go "unsaid," but the implication is very clear - if the convening authority "sees fit" to bring about a court-martial, then the accused can be assumed to be guilty. What's special, or even topical, about A Few Good Men movie is it speaks to how military honor can be so readily suborned by the authoritarian impulse. And second, how the same honest pride - not to mention competence - is necessary to bring such posturing would-be tyrants to justice. The main issue the movie touches upon is military justice. A good marine abides by the following code: 1. Unit 2. Corps 3. God and 4. Country For this code to be at its effective best, it must be governed by truth and justice. What happens when truth and justice fail to be active participants of this code? Justice has been defined in many ways...

...stability. But ceramic caps have a very less ESR and are useful in bypassing high frequency noise but cannot provide the compensation to maintain the loop stability as the dominant zero is at a very high frequency. So LDO’s with ceramic output capacitors have an additional series resistor R comp which performs the functionality of ESR with the C comp to provide the additional zero required for compensation. Load dump occurs when the battery is disconnected when it is being charged by the alternator. A huge voltage spike of 120V is generated and can take up to 400ms to decay. Signal diode arrays can also be used in digital and computer circuits to protect high speed data lines or other input/output parallel ports against electrostatic discharge, (ESD) and voltage transients. By connecting two diodes in series across the supply rails with the data line connected to their junction as shown, any unwanted transients are quickly dissipated.

Furthermore, it represents my own opinions and not necessarily those of the University. Signed __________________ Date _________________ Abstract Windsor Airmotive Asia Pvt Ltd is the leading repair and overhaul shop for CFM56-3/-5/-7 series turbine engine components. During development of a new repair scheme, to replace the inner inducer and outer inducer of the Forward Inner Nozzle Supports (FINS), a major challenge was encountered at the Electric Discharge Machine (EDM). A trial done on a scraped part revealed that 112 vanes have to be aligned before it can be machined by EDM to the inducer. By introducing a semi-automated machining fixture, the alignment of the vanes will be made easier, on top of increasing the utilization of the EDM by 20%. The aim of this project is to develop a machining fixture for the EDM so that the alignment of 112 vanes will be made easier.By developing this fixture, the company can expect to reduce the scrap rate of FINS. These FINS are often scraped because of the inducer wall rub marks that exceed the limits given in the engine manuals.This will also be beneficial to the customers by helping them to reduce their overhaul cost for the engine rebuild. This will...

...Colorfastness refers to the resistance of color to fade or bleed of a dyed or printed textile materials against water, light, rubbing, washing, perspiration etc. to which they are normally exposed in textile manufacturing and in daily use. Colorfastness to Rubbing Colorfastness to rubbing test is designed to determine the degree of color which may be transferred from the surface of a colored fabric to a specify test cloth for rubbing (which could be dry and Wet). Crockmeter is the main equipment used in this test. Crockmeter uses a standard pressure and rubbing motion to provide reliable and reproducible test results. Specimens are positioned on the base of the Crockmeter and held in place with the sample holder. The rubbing action is provided by an acrylic "finger" which moves in a straight line with each complete turn of the crank. The reciprocating load arm is weighted to provide a constant 9N load on the sample at all times and a mechanical counter keeps track of completed cycles. Then, the result of the specimen is evaluated using the grey scale of staining. Colorfastness to Washing The main test method of the colorfastness to washing is carried out called AATCC standard detergent WOB (without optical brightener). The test measures the resistance to water of any colored textiles. Launder-moester is the main equipments used with the help of grey scales. Testing procedure (Usages) 1. Attach the multifiber fabric to specimen by sewing or stapling. 2. Place the sample...

...At this time, unfortunately, a convergence in terminology has not been forthcoming and, hence, a definition of the term Micro-Machining to be implied in the context of this assessment is in order. In principle, one may take two viewpoints:(1) The first viewpoint may define Micro-Machining as the collection of all cutting operations that are performed on micro/meso-scale components and products that fall into the 100 μm to 10,000 μm size range as shown in the figure below. The Micro-Machining regime is characterized by the requirement of producing high accuracy complex geometric features in a wide variety of materials in the above-defined size range. These requirements impose the use of considerably downsized tooling (micro-tools, e.g. endmills in the 50 to 500 micron diameter range), small undeformed chip thicknesses and feedrates (submicron to a few microns) and speed settings (50K to 200K RPM might not be uncommon) that would be considered technologically infeasible at the conventional macro-scale. As a consequence, the principal distinction between Macro and Micro-Machining operations emerges and manifests itself as the dominance of ploughing and rubbing phenomena at the cutting edge over shearing and the necessity to take micro-structural effects into consideration. (2) The second viewpoint approaches the definition of the Micro-Machining regime from the standpoint of the magnitude of the undeformed chip thickness being removed in the cutting process. It is difficult to define...

...Memorandum To: CEO of Toy Company From: Elementary Division Manager Date: 10/22/2014 A. Constructive Discharge as a Legal Concept relevant to this scenario The company attorney has informed us that Mr. Smith, a former employee, has filed a claim of constructive discharge under Title VII of the Civil Rights Act of 1964. Mr. Smith claims due to our new production schedule we practiced religious discrimination by forcing him to work on a religious holy day. According to the AAUW “Title VII of the Civil Rights Act of 1964 is a federal law that prohibits employers from discriminating against employees on the basis of sex, race, color, national origin, and religion.” (AAUW, 2014) Contructive discharge happens once an employeer engages in a practice that creates an intolerable work life for any of the above listed protected groups. According to the University of Chicago Law Review, there are two different tests that have been developed for deciding if an employee has been constructively dishcarged. The first test is a reasonable person test. This test simply looks at a reasonable person and decides if they would have found the conditions to be inolerable. (Finnegan, 1986) The next test is an intent test. This test requires the plaintiff to show that the conditions were intolerable but also show that these conditions were created with the intent of forcing the employee to resign. (Finnegan, 1986) I believe Mr. Smith’s allegations will not pass either test. ...
