Network Remote Access - Essay Example On this logical connection data packets are constructed in a specific VPN protocol and are encapsulated within some other carrier protocol then transmitted between VPN client and server. The name itself signifies that the client has to it self has to initiate or to manage the connection. The VPN client has to first establish a connection to the carrier and then the VPN client will create a tunnel to the VPN server over the logical live connection. In compulsory tunneling the Internet service provider has to manage VPN connection setup. When the user in this case an employee away from the office tries to establisha connection to a local carrier, the ISP inurn establishes a connection to the VPN server. If we look from the clients point of view, Compared to voluntary tunneling compulsory tunneling sets up a VPN connection in just one step instead of two steps in a voluntary tunneling. This kind of tunneling authenticates the users or the client and then connects them with the specific VPN servers using specified logic built into the broker device. The network device that comes into picture for compulsory tunneling is some times called FEP (front end processors), Network access servers (NAS) or point of presence (POS). The basic function of compulsory tunneling is to hide the details of server connectivity from the VPN client and then moves it's control from client to local carrier.

The network device that comes into picture for compulsory tunneling is some times called FEP (front end processors), Network access servers (NAS) or point of presence (POS). The basic function of compulsory tunneling is to hide the details of server connectivity from the VPN client and then moves it's control from client to local carrier. The additional burden for the service provider is the he has to install and maintain the front-end processors. There are number VPN tunneling protocols available, which are presently implemented in various VPN applications. The most widely used are. 1. Point-to-point tunneling protocol. (PPTP) 2. Layer Two Tunneling Protocol (L2TP). 3. Internet protocol security (Ipsec). 1. Dialup connection using telephone line. Using a dialup connection also a connection can be established to a VPN server from a remote place. But dialup connection is adequate to connect to an E-mail server. It lags in terms of continuous contact with the server due to frequent disconnection. So, connectivity and reliability is not associated with this type of connection, which are required for intensive and secure business applications 2. Dialup connection using mobile phone. VPN connectivity to the company's network using a mobile phone is also possible with a hand set having GPRS feature. This could be an ideal way for the employees who are always on the move. Connecting to company's network using mobile phone for prolonged duration is not advisable since there are chances of disconnection from the servers of the office network due to congestion in cellular network during peak time. Another disadvantage using a cell phone is that an employee has to compromise with the speed offered by the service provider. During an Internet

Cylinder Taper and Cylinder Out of Round

Cylinder Taper and Cylinder Out of Round Aditya Patel Equipment Utilized An assortment of hand tools, pullers and specialty measuring tools were used during this assignment Health and Safety Precautions Safety boots and glasses were mandatory in the shop Proper lifting techniques, and getting help lifting was very important Unit Identification GM 3100 Engine References GM 3100 service manual, and our classroom text book were used. Lab notes and internet were used for some of the notes. Method 1. List all the steps needed to measure cylinder taper and out of round. a bore gauge calibration unit was set up by using fixture and calibration unit the bore gauge was placed in this unit and calibrated using the micrometre scale on the unit. To calibrate for specific bore, use the standards. For example, for 4.406 bore, install 4.000+ standard and set the scale to 0.406. Bore gauge is calibrated until the dial shows 0 on it. Or more adjustment should be done. the bore gauge was then placed inside the cylinder at Top thrust surface and rock the bore gauge front and back until dial goes up and comes back. Note the highest reading, the dial reaches. Do same for bottom thrust surface. To measure the cylinder out of round, measure top thrust surface of the cylinder but perpendicular to the first measured. Now compare both reading for top thrust surfaces readings. If the difference between the measured reading is more than 0.0005 then the cylinder is out of round or else, it is good. To measure the taper, subtract the reading of bottom thrust surface from top thrust surface. If the reading is more than 0.0008 then cylinder is not good. Cylinder Taper is the difference of the diameter between top of the cylinder bore under the ridge and bottom of the cylinder Cylinder out of Round is the difference of diameter when measured parallel to crankshaft and then perpendicular to the same at top of the cylinder using bore gauge. Method Continued   Ã‚   2. Document 2 methods of measuring piston to cylinder bore clearance. Feeler Strip Method Remove all compression and oil control rings from pistons Invert the piston and place it back in the cylinder in upside down position with feeler strip. The feeler strip should not be on the piston pin hole. After piston is placed in the cylinder slowly take the filler gauge out. While taking the filler gauge out, if it feels too hard or loose the try different size of the gauge until you get the perfect size. The perfect size of filler gauge should not feel too tight or smooth while taking it out. (Measuring clearance using feeler strip) Calculated Method Measure the diameter of the piston across the skirt with well calibrated micrometre. Note the reading. Now using the bore gauge measure the cylinder diameter under the ridge. Record the reading. Now subtract the piston diameter from cylinder diameter. The measurement achieved is the piston to cylinder clearance. Note that before taking any reading the micrometre should be well calibrated and the surfaces should be cleaned. (Bore gauge measuring the cylinder diameter) (Measuring piston diameter using Micrometre) 3. Construct a chart listing cylinder, piston ring and crankshaft clearances. Located under observations heading 4. Record how to check ring clearances. (side and end) Side Clearance Remove all compression and oil control rings from pistons Clean the piston ring groove before measuring. For measuring the ring clearance, the ring doesnt need to be installed in the piston. Gently place the ring in the groove. After placing the ring measure the clearance with the help of feeler gauge between the ring and upper edge of the groove. Compare the measured ring clearance with the manufacturers specification. If the measured clearance is more then the manufacturers specification the change the ring. (Measuring Ring Clearance using Feeler Strip) End Gap Remove all compression and oil control rings from pistons Place the ring in the same cylinder from which piston come out. Using the piston slowly push the ring in the cylinder. Then measure the gap between the two ends of the rings with filler strip. The filler strip should not too hard or too smooth to pass between the two ends of the rings. Then do same for the second ring and note the measurement. Compare this measurement with the manufacturers specification. If the measured end gap is more then the actual specification the change the ring. (Measuring piston ring end gap using feeler strip) 5. Describe 2 methods of measuring crankshaft bearing clearance. Plastigauge Method remove the main bearing caps from the block and clean the surface of the crankshaft journals with a clean rag. Now place a piece of plastigauge according to the width of the journal. Install back main bearing caps on their same position as before. Check that the bearings are in the correct direction. Install the bolts and tighten them with torque wrench at the manufacturers specification. Now remove the main bearing caps and check the spread of plastigauge. Compare with the marking given on the cover of the plastigauge and note the reading. Now compare this reading with the actual specification. Before installing main bearings back, carefully wipe the plastigauge marks. (Measuring the Crankshaft bearing clearance using plasti gauge) Calculated Method Measure the crankshaft journal diameter using a well calibrated micrometre. Measure every journal two times both perpendicular at each other. Note every reading. Now put the bearing journals back on. Use torque wrench to tight the bearings with specified torque. Using inside micrometre or bore dial gauge measure the diameter of the bearing. Note the reading. To measure bearing clearance, subtract the crankshaft journal diameter measurement from bearing journal diameter. The allowable clearance for crankshaft is between 0.0008-0.0025. 6. Explain what causes cylinder taper and cylinder out of round Cylinder Taper is caused by wear caused by friction and combustion cause the bore to be cone shaped. Cylinder Out of Round is caused by pressure created by piston rings to the cylinder walls.

The Communist Manifesto Essay -- Communist Manifesto Essays

The Communist Manifesto   Ã‚  Ã‚  Ã‚  Ã‚  Marx describes the problem in great detail in the first chapter. He feels there is a problem between the bourgeoisie and the proletarians. The bourgeoisie were the oppressed class before the French Revolution and he argues that they are now the oppressors. The proletarians are the new working class, which works in the large factory and industries. He says that through mass industry they have sacrificed everything from the old way of religion, employment, to a man’s self worth and replaced it with monetary value. He is mad that the people of ole that use to be upper class such as skills man, trades people, & shopkeepers, are now slipping into the proletarians or working class. He talks of the bourgeoisie getting to be so greedy that they are forced to nest all over the world to hock their goods. This is talking about the new import and export system that has formed. He says the working class has to deal with the flux of the market and is disposed of more eas ily than the machines used in the market. He says that they actually become part of the machine while working. Doing the simplest and most monotonous part of the job. In this new system Marx says â€Å"as repulsiveness of work increases, the wage of work decreases†. He also prophesizes that machines will become so advanced that the wages for man will become one extremely low rate. He says the proletarians live a life of exploitation. By being exploited at work in the w...

Cusick and Her Lesbian Relationship with Music Essay

In the essay â€Å"On a Lesbian Relationship with Music: A Serious Effort Not to Think Straight† by Suzanne G. Cusick, she brings up an interesting topic about the connection between her being a lesbian and her being a musician, a musicologist, if there exists any. I’m especially interested in the â€Å"power system† and the link between musicality and lesbianism she mentions in this article. Here, I’ll try to analysis them in detail and relate them with other issues in music and sexuality, exploring them in a more general picture. Cusick redefines the concept of sexuality in her essay, as the way of â€Å"expressing and/or enacting relationships of intimacy through physical pleasure shared, accepted, or given.† According to her, this process of expressing and enacting can also be found in our musical activities, where the circulation of physical pleasure can be experienced as well. Thus, she says that our musicalities and our sexualities are â€Å"psychically next-door neighbors.† (70) I need to claim that this idea of her amazes me. From my previous musical experience, I’m pretty sure that music is a subject highly intimate for me. For instance, I usually have reluctance when I’m asked to sing or perform a song written by myself, even if I think it is a brilliant one. And this won’t happen if the song is someone else’s. In my opinion, music, especially my own music which I’m personally attached to, is an expression of my true self, and that identity and personal characteristics contained in it makes it so special that I won’t be willing to share it with others, unless it’s someone really close to me. Another fact that I think will support Cusick’s idea is that different people always have different opinions towards the same piece of music. No matter how the composer perceives it, the listener usually has the tendency to relate it to his/her own personal experiences, which differ from person to person. It is reasonable to think that music is a symbol of someone’s personalities and characteristics, because of the intimacy the music creates. Therefore, I believe that there exists a connection between the musicality and the sexuality of a certain person, since both of them are revelations of his/her true identity, and we can examine our own behaviors on both of them. In other words, these two factors are connected because of the person who they belong to, and they are contained in the system of his/her perspectives. Cusick also explains in her article what does it mean to be a â€Å"lesbian† and how to define sexuality, which are essential questions if we want to relate it to music. From her point of view, the essence of one’s sexuality and the element of all relationships is the power system. An example that can explain this is what musicologists say about the masculinity in Beethoven. In Susan McClary’s opinion, there exist musical constructions of gender and sexuality. She regards the field of music and musicology as male-dominated, since the masculine norm and the distinction between genders are deeply rooted in music, such as masculine and feminine cadences, rhythms, gendered major and minor triads, etc. (7) She also analyzes Beethoven’s music, which to her contains â€Å"pounding†, â€Å"thrusting† gestures that represent masculinity. (75) On the contrary, in Sanna Pederson’s article â€Å"Beethoven and Masculinity,† she redefines the concept of masculinity and the link between it with Beethoven. She states that we can find an alternative approach, arguing that we regard Beethoven as symbol of masculinity because of the overwhelming idea that viewing woman as â€Å"as unchanging, eternal essence, as the opposite of the dynamically striving and achieving man.† (326) Matthew Head also approaches this from another perspective by examining the heroic in Beethoven’s works, finding many cross-dressed he roines. (132) It’s notable that although there is importance put on female characters, women usually need to conceal their sexuality and transgress the gendered norms in order to serve as the epitomes in the aesthetic sphere. This shows that, no matter what kind of connection there exists between Beethoven and masculinity, there does exist a power system that emphasis on the inequality between men and women, where women as less – worth less, power less – man, in both our society and in music. Whichever argument we believe, we should admit the extensive presence of the power system in our society, and in practice, it can be found both in music and in many relationships between people, especially heterosexual ones. The most significant point of view of her in this essay, I think, is that she believes being a lesbian is an escape from this power system: As a woman, as a non-dominating and non-power woman who loves another woman in her relationship, the flow of power can exist in both directions, as opposed to a heterosexual relationship where a man typically plays the dominating and powerful part. And Cusick believes that this is the beauty of a lesbian relationship: it’s about â€Å"organizing the force field of power, pleasure, and intimacy that refuses the simple binary opposition male and female†. The lack of opposition creates a world that scrambles the usual components of â€Å"man† and â€Å"woman†, and a world â€Å"free of fixed categories.† (73) This reminds me of the documentary â€Å"Paris is Burning†, which stunned me with its idea of celebrations of a powerful expression of personalities, without any restriction of boundaries. There, what matters is the personal prides, which are fully showed in the â€Å"drag nights† in New York. Cusick further explains the elements in a lesbian relationship as the â€Å"power/pleasure/intimacy† triad. (71) From my understanding, this is indeed an appropriate way to observe a relationship. As I mentioned before, power is an important factor that circulates within the relationship. What’s more, pleasure and intimacy are objectives that we usually want to achieve when we are involved someone we love, and thus they are essential bolsters of a relationship. As Cusick says, this triad can be experienced more freely in lesbian relationships, because without the power flowing only in one direction, the equality and balance between the two lovers can give them more intimacy and pleasure, both physically and psychically, from their relationship. Hence, in Cusick’s article, being a lesbian is not merely a sexual orientation; it is also the way one prefers to behave, to organize the relationship to the world in a â€Å"power/pleasure/intimacy† triad. It’s a way of refusing, breaking, and creating, and to cope with the world in a way that she prefers. And these behaviors can also be detected in a person’s musicality, which is also built in his/he r identity. More interestingly, Cusick talks about the â€Å"lesbian relationship† she has with music. She treats music as a woman, and a woman that can be a lover, and also the beloved – as in a lesbian relationship where the power circulates both ways and cross without boundaries. (78) In the article â€Å"Musicality, Essentialism, and the Closet† written by Philip Brett, he also discusses music be perceived as feminine. Brett says that in history, music has often been considered a dangerous substance, â€Å"an agent of moral ambiguity always in dander of bestowing deviant status upon its practitioners.† (11) By describing music as a woman that â€Å"ravish† our sense or our soul, people from the medieval and early modern times let us see how close music and sexuality can be. This also makes Cusick’s treating music as a female lover more sensible. Another idea of her that interests me is that she thinks her choice of music can reflects her sexuality. She says that her love for hidden relationships and the tension between the ostensible structure, which represents the tension between a social norm and â€Å"a very high degree of eccentricity,† suggests her escape from the power system. Also, she dis-prefers music hat upset this power equilibrium. (77) She explains this by saying that her â€Å"lesbian self† let her prefer certain kinds of music and reject some other kinds. This makes me think about in general, how people’s choices of music reflect their sexuality and identity, and to what degree. I agree that the choices of music can reflect that person’s personality to some extent, but I also believe that the music he/she listens can shape that person into the qualities and personalities that the music wants him/her to have. The same as Cusick’s relationship with her music, there is a counter -influence here as well. Rentfrow and Gosling found in their research that people’s music preferences are related to a wide array of personality dimensions and self-views. If the links between music preferences and personality do exist, we can easily infer that our choices of music reflect our identity, which also links to our sexuality. Besides, we can always see the influences of music on people. It has been shown by Frederick H. Martens that music exerts its collective influence in the course of history. He also says that as an individual influence, music is one of the factors in the life of kings and rulers, which also â€Å"has exerted a more or less direct influence on the destinies of countries and peoples.† We can see clearly from his article that music can significantly affect one’s views and thoughts on this world, therefore it is an important element in directing people’s personality and characteristics. Hence, the relationship between a person and the music he/she listens is a mutual one. People’s preference of music decides the music they choose, and what they choose can reversely change them as well, directing them into the qualities that can be defined through that music. This can also illustrate Cusick’s point that her relationship with music is about the power dynamic that circulates both ways between music and her, and this relationship highly resembles the one between lesbian lovers. Thus, the link between music and sexuality is obvious. Furthermore, I’m wondering about how the connection between identity and sexuality works in other subjects and fields of study. Cusick says in her article that she does not address the texts of music because she thinks that they tend to trick us into staying in a â€Å"power-over paradigm that is mighty close to the regime of compulsory heterosexuality.† Personally, I don’t entirely agree with her on this. In my opinion, other subjects such as literature and art can also illustrate one’s identity, thus they can represent people’s qualities through the â€Å"â€Å"power/pleasure/intimacy† triad as well, and so does texts in music . The reason why Cusick thinks that focusing on texts can deviates us is that her love and professional interests in music leave her only looking at music as an intimate lover. But for people from other fields and domains, their subjects can be treated as lovers and beloved as well. For example, it is reasonable to imagine a poet feels extreme intimacy in his relationship with poems. Cusick mentioned by herself in the notes that she can also find tremendous joy from cooking, and she loves to peel fruits and vegetables without a knife, because she believes it will create wholly pleasurable experiences. (83) I would not say Cusick is also in love with vegetables, but what she says can suggest that pleasure and intimacy do not solely exist between people and music. As Pygmalion can fall in love with the statue he carved, why can’t a songwriter build a romantic tie with the texts of music he wrote? In other words, as long as we have passion, the relationship between people and his/her subject of study can be developed in any area, within which we can find its connection with sexuality. This essay of Cusick is not very long, but the notions it contains, I believe, are really valuable sources of thoughts if we want to explore the relationship between music and sexuality, especially when we want to discover it from a perspective about our own identity and personal characteristics. Cusick has nicely shown that the boundary between music and sex can be a blurred one, where both are means of negotiating power and intimacy through the circulation of pleasure. Here, the most important is the people that involves both with music and with sex, intimately experiencing them and wholly mingling with them. As Cusick says, what really matters is neither music nor sex, but â€Å"the transcendent joy of being alive, not dead, and aware of the existence.† (69) Works Cited: Brett, Philip, Elizabeth Wood, and Gary Thomas.

Managed Globalization Essay

While imperialist thinking wreaks havoc around the world, the trend toward greater globalization offers hope, provided that adequate efforts are made to ensue that globalization is managed well. Globalization is the most popular trend in international economics. Increasing integration of world markets and exchanges of information and technology are definitely expected to help the least developed nations, thereby bridging the gap between the haves and the have-nots. Thus, the thesis of Bhagwati’s book, â€Å"In Defense of Globalization† – that, in fact, globalization helps the poorest people of the world – must be agreed with. After all, foreign direct investments are an extraordinary boost for the economies of the developing world. Moreover, by importing and exporting more goods and services than before, a developing nation may very well increase its income and also improve the standard of living of its peoples. It is generally believed that an increase in international trade is accompanied by an increase in income inequality, seeing that the majority of the people in developing nations are poor and cannot afford to purchase relatively expensive foreign goods in the local market, nor form gigantic enterprises to sell to the foreign public. Furthermore, globalization involves the risk of foreign companies taking advantage of the undeveloped regulatory structures in developing nations. As an example, a foreign water company in Argentina, after the mass privatization of Argentinian business, was said to have been very ethical before it entered Argentina. The company had connections with France and the United States. All the same, the company turned to poor service in Argentina soon after privatization. The water company was eventually taken over by the Argentinian government for its careless, irresponsible behavior. If managed correctly, though, globalization is expected to help our world in significant ways. The famous observation of Thomas Friedman must also be considered in this analysis: â€Å"No two countries with McDonald’s have fought a war against each other since each got its McDonald’s. † Indeed, peace is conducive to global economic growth. But, so is equality. Even though the gap between the haves and the have-nots has been widening in recent years, good management of globalization may work wonders for the global economy.
