I need some assistance with these assignment. modern day attacks against firewalls and vpns Thank you in advance for the help! The uses of VPNs help companies to access the internet at the time of travel. It is also used by the individual internet operator to secure the wireless connection. VPN is an important technological advancement for remote workers as well as organizations to share the data privately. The security issues surrounding VPNs are cracking of offline passwords, deficiency of account lockout, poor default formation, and VPN thumbprint among others (Hills, 2005). In a similar context, firewalls are the security system used to secure the flow of information between the two networks. Firewalls place a bottleneck between the networks which ensures the privacy and confidentiality of the data shared between the two networks. There are two types of firewalls as ‘packet filtering firewall’ and ‘stateful inspection firewall’. The common threats pertaining to firewalls include attacks from malicious codes such as viruses, worms, and information theft among others (Rao et al., 2011).

The technology of firewalls was first established in 1980 and since then it has undergone several modifications and alternations. Firewalls are integrated security systems designed to secure networks from unauthorized access. Firewalls are also useful for protecting the outside fire. Firewalls are also considered as a system of network security that controls the flow of traffic over the network created by a set of protocols (Brown University, n. d.). Firewalls act as a ‘software solution’ and ‘hardware appliance’. Firewalls can also be defined as security measures, which protect the local systems as well as network systems from potential threats. The two types of firewalls are packet filtering and stateful inspection firewall. A packet-filtering firewall allows the flow of packets that meets certain specific criteria.

Write 2 pages thesis on the topic social class in the us. Sawhill, Isabel (2006) in a Policy Brief stated that while the US economy performed well, most of the benefits of such success were reaped by those at half top of the income distribution strata, especially those at the top one percent (or those with an income of more than about $400,000 in 2006).

Write 2 pages thesis on the topic social class in the us. Sawhill, Isabel (2006) in a Policy Brief stated that while the US economy performed well, most of the benefits of such success were reaped by those at half top of the income distribution strata, especially those at the top one percent (or those with an income of more than about $400,000 in 2006).

In the same Policy Brief, Sawhill confirms that indeed, the class still matters in the American

Society, stressing that it takes at least five generations to totally free one from circumstances of birth or family background. Sawhill adds that as the gap widens among the income levels or groups, it has become harder for people to move up, as the topmost of the ladder becomes more and more solid and strong, accumulating more and more wealth.

Immigrants, illegal or otherwise, represent cheap, reliable labor for American businesses. The documented and legal immigrants mostly have no education or reached only high school level, which makes it harder for them to land on high-paying jobs. Even their children tend to not continue to go to school but instead engage in jobs to augment their families’ incomes.

Education, they say, is the great leveler. However, the US does not provide equal access to quality education to its people. The majority of the immigrants’ kids go to public schools which are below par the other schools across the nation. Even the funding for Bilingual Education has been debated upon, most probably towards its abolition.

It is therefore no wonder that recent trends had been that these immigrants are going back to their homes, primarily to seek better opportunities at their homelands, and secondly to be near their loved ones back home. The US may be a land of opportunity to some, but definitely not for everyone. It is not really a matter of the hardworking, persistent winning the race. It is still a matter of who one’s parents were, where one went to school, how much power does one hold, among other factors that really matter in order to live the American Dream.

prepare and submit a paper on submarine volcanoes.

Your assignment is to prepare and submit a paper on submarine volcanoes.

&nbsp.

“Much like volcanoes on dry land, an underwater volcano is a fissure on the earth’s surface where lava is produced and can erupt.” (Raine, 2010)

The causes of a volcanic eruption cannot be analyzed without an understanding of the earth’s structure. The core of the planet is boiling and contains a reservoir of molten rock called magma. This magma is bounded by more relaxed layers of rock that form the earth’s crust, including both the ocean floor and land, which increases the internal pressure caused by heat. However, when the crust releases the tension from any opening or when the internal pressure can overcome the external force, the magma breaks through the earth’s surface. It erupts, releasing the magma in the form of molten lava and ash.&nbsp.(Raine, 2010)

The essential characteristics of submarine volcanoes are that the eruptions from the volcanoes are affected by the pressure and temperature of the water around them. (Topinka, 2003)

“…the volcanic phenomena take place very much in the same manner from the bottom of the sea as from the open surface of a continent, subject only to modifications produced by the lower temperature of the surrounding medium, and the greater external pressure, caused by the weight of the overlying column of water, which in this case becomes one of the elements of the repressive force.” (Scrope, 1862)

In shallow waters, this lava is cooled so rapidly that it transforms into ‘black sand’ or volcanic debris almost instantaneously or forms volcanic glass. (Palande, 2011)This debris is either piled-up around the volcanic vent or settles down along the seafloor. (Topinka, 2003) Eventually, the piling up emerges above the ocean’s surface in the form of volcanic islands, some of which can be seen in the south Pacific and the North Atlantic oceans. (Tufty, 1969.) (Crouse, 2012).

In the deeper part of the ocean, volcanic activity resembles the volcanoes on land in terms of shape and flows&nbsp.(Topinka, 2003). They are seen to be slightly steeper as the water speeds up the hardening.&nbsp.(Rafferty, 2011.

research paper on middle-aged and older people observation. Needs to be 5 pages.

Need an research paper on middle-aged and older people observation. Needs to be 5 pages. Please no plagiarism. It is well known that no two persons are alike and I have found the same in almost every body but the most significant and identifiable aspect what I found is that the people within a particular age group tend to behave in almost the same manner. This almost similar behavior might be due to similar socio economic background from which they come from. Some of the middle-aged people coming from somewhat rich background tend to behave in a more dignified manner even though they are older than the people who are from a poor background.

With this observation what I really came to know is that older people who lead significantly decent life through ought their life have a deeper understanding towards their life and will try to act accordingly in public. On the other way round poor middle aged and older people do not try to behave accordingly in public and according to the situation. On older people there past life influences their present state of behavior a lot. I have observed six people who are all above fifty-eight years. The first person I have observed is an old man who has retired long back from Military Air force. He has receding hairline and is slender built but very active, red in color, very lively person and pretty intelligent, was very communicative, very popular among the people coming to the library. I was observing this person from almost a week and could gather most of the information related to by simply over hearing the discussion between their old friends in the public library. Since he was working in Air force earlier he is quite informative and communicative too. He has three children and all are working but no one is yet married. Being slender built he is very energetic and his actions are not at all like an old man. He even helps his fellow old men in climbing stairs. He is very popular among women coming to the library.

Going Out to Eat at a Nice Restaurant. The work is to be 2 pages with three to five sources, with in-text citations and a reference page.

I will pay for the following article Going Out to Eat at a Nice Restaurant. The work is to be 2 pages with three to five sources, with in-text citations and a reference page. There were many occasions where we would go out to eat at a nice restaurant because of a special occasion, i.e. birthday, Christmas, or just a general celebration, but none of these really stick in my mind. The reason is that all of these things came around once each year so it was more like a ritual or a habit rather than a celebration. The time that I remember the most is when my family and I went on our holiday out of the country. It was a small island located in the Caribbean, and it was a special moment in my childhood. The setting was remarkable as the waves crashed against the shore while a magnificent sunset occurred daily. There was one restaurant on that island that I shall never forget because of the awesome feeling I got from the delicious food that they served.

Once we arrived to eat, the waiters and waitresses came to take our order. My siblings and I were given permission from our parents to select whatever dish or dishes we wanted because we would likely never be able to return here again. As all kids do, I immediately fixed my eyes on the most expensive item on the menu. It did not occur to me at that young age that price doesn’t necessarily equate to quality, but that did not matter to me. I was feeling famished and I couldn’t wait to tuck into the most delicious dinner dish I had ever tasted. While we were waiting for our food to arrive, we noticed the ambiance in this particular restaurant. There was a young lady quietly playing the violin over in the corner, while the flickering lights created a sense of calm over the whole place.

After some time our food was brought out to us. not the main course, just the entrée. As I chose not to order one of these, I had to wait a little bit longer for my food. After the rest of my family had finished their appetizers, we noticed a long-bearded man come into the room and begin to play his guitar. He was quite talented with this musical instrument, and the remarkable sound coming from his guitar kept our minds off the impending arrival of our main courses.

Write 7 pages with APA style on Analysis of Articles about Gallium Arsenide.

Write 7 pages with APA style on Analysis of Articles about Gallium Arsenide. In the first article, the experiment was ‘Metamorphic Graded Bandgap InGaAs–InGaAlAs–InAlAs Double Heterojunction P-i-I-N Photodiodes.’ The authors of the article are Jae-Hyung Jang, William E. Hoke, Gabriel Cueva, Patrick Fay, P. J. Lemonias, and Ilesanmi Adesida. The experiment involved fabrication of high-speed metamorphic double hetero-junction photodiodes on GaAs substrates for the purpose of long-wave-length fibre optical communications.

According to Jae-Hyung Jang, et al, high speed in InGaAs photodiodes are very important components in extensive bandwidth optical fiber communication. Moreover, these photodiodes have been fabricated on InP subtracts as a result of the web matching of In0.33 Ga0.47 As to Inp. Jae-Hyung Jang, et al denote that Inp substrates have numerous practical shortcomings as compared to GaAs, that have encouraged the development of metamorphic device structure conducted on GaAs substrates.

As per the authors of the article, the growth of excellent InGaAs–InGaAlAs–InAlAs heterostructures on GaAs substrates was made possible by the superiority linearly graded quaternary InGaAlAs metamorphic buffer layer (Jae-Hyung Jang, et al. 1). Photodiodes achieving a small dark current of 500 pA, a 3 dB bandwidth of 38 GHz at 5 V reverse bias for 1.55 m light, and responsivity of 0.6 A/Wwas enabled by the use of a fresh double hetero-structure employing an InGaAlAs ophthalmic impedance matching layer, a large band-gap I-InAlAs drift region, and a chirped InGaAs–InAlAs super-lattice graded band-gap layer (SL-GBL). Moreover, the authors of the article examined the effect of amassed charges at the InGaAs–InAlAs hetero-interface. This examination was carried out through a comparison between photodiodes with chirped InGaAs–InAlAs SL-GBLs and InGaAs–InP unexpected sole heterojunction photodiodes and the dark currents of InGaAs–InAlAs. By including chirped InGaAs–InAlAs SL-GBL between the InAlAs drift layer and InGaAs absorption layer, the authors suppressed the charge build-up effects observed in abrupt hetero-junction devices (Jae-Hyung Jang, et al. 1).&nbsp. &nbsp.

Nonetheless, each office should have a computer with restricted use:The Sever and other computers in the department are linked by certain internet cables while the remainders are connected by an 800.11 g wireless network with an access port. All machines, laptops and other computers run Windows XP Professional (Erbschloe, 2005).After comparing each computer against a checklist in a security guide for the department, it is identified that virus protection was missing on six computers, antivirus was not updated for three computers, many users complained about spam while no protection was in place.

A random sampling found that many people did not use passwords (International Maritime Organization, 2011). None of the computers was password protected. The department had the insurance people the previous year. thus, the department had ensured a good quality on all doors, alarms and window locks. However, no computer had a serial number etched on the case while the department did not also have a log of the serial numbers. The department faces the risk of email and password cracking by intruders who want to access the weapon information (Vellani, 2007). hence, the use of passwords must be ensured.

Ensuring that weapons or arsenals used by the military are listed in documents that are kept secret and accessed only by specific persons accredited by the department. The trusted people with such information should be protected and their moves monitored to prevent sharing of important information with other people.Restore procedure sand review backup. This would ensure that user data is stored on the server or even copied across regularly before reviewing the backups. Daily backups should be implemented and ensuring that a full backup is password protected and encrypted (Hunsicker, 2008).

After completing the first draft, the directors shall review it together with the company attorney general before rolling it out.&nbsp.

Hi, I am looking for someone to write an article on project management skills in a building conversion Paper must be at least 1500 words. Please, no plagiarized work!

The first crucial step is to seek a structural engineer to do an audit of the existing concrete block posts. This will need his approval for our company to know whether the existing structure can support another floor on top. (Larson, 2010). That is, whether the concrete block in existence is strong enough to have another floor up as 2nd level or another down as the basement. Depending on the support, the approval may be issued or not. Afterward, we can proceed to the preliminary design of the second floor.

That is the floor layout of the second floor required among other things like structural and electrical design, ventilation, insulation, vapor barrier, and drywall installed on the walls and ceiling.These specifications will be tailored to the client of this building. A detailed assessment of the existing building will be done to check the integrity of the current building, the kind of foundation, parts of the building that are intact or need re-designing to fit in the preliminary design. This will be done with the assistance of the current building’s construction team, the building inspection unit from the local authority, and the proprietors of the new building (Larson, 2005).

We may need to consider all renovations are done previously and any recommendations from the local authority inspection unit.After the detailed assessment is performed, a provisional design is done incorporating the findings in the earlier conducted detailed assessment. The design is presented to the client for his approval and finally forwarding to the local authority for the purposes of seeking the building permit. Once the building permit is issued, the conversion works can officially commence with other revisions being made on the prior design if necessary but still approval from relevant authorities is mandatory.

This is how this conversion will generally go. The detailed procedures will be modeled within the Microsoft Project 2007.

Since the emergence of online forms of communication such as YouTube, there has been a battle fought between YouTube and the broadcast media with the intention of winning, engaging, and retaining the audience. Although broadcast media such as TV are viewed as the winner of this battle, for the time being, expert media professionals opine that YouTube would eventually dominate broadcast media in the near future. It is obvious that the way the world lives has changed significantly over the last decade, and in this dynamic digital world, consumers have switched their demand from TV to YouTube for meeting a significant per cent of their video content needs.

YouTube videos provide the audience with extensive exposure in order to serve their information and entertainment needs and to connect with like-minded individuals. Another benefit of online forms of communication like YouTube is that people can respond to the video contents and actively interact with others. However many people still hold the view that YouTube is not an authentic medium as anyone is free to post videos on YouTube. This paper will evaluate whether or not online forms of communication such as YouTube involve a new kind of mediated authenticity absent from broadcast media.

The recently developed online forms of communication such as YouTube are fast gaining wider audience coverage mainly because of their user-centred features. YouTube has invested heavily in improving and popularizing its product/service offerings in an effort to obtain a clear dominance over the broadcast media. For this, YouTube tries to form close relationship production companies and other businesses and to enhance its pay-per-view films package. Recently, it has launched projects like YouTube Comedy Week to promote the interests of consumers across the globe.

Experts suggest that YouTube’s ambition to grow up can be achieved sooner than what traditional broadcasters expect.While considering the aspect of authenticity, it is relevant to say that YouTube allows communicative practices with the intent to establish new forms of mediated participatory culture.&nbsp.

Verbal Working Memory. The work is to be 6 pages with three to five sources, with in-text citations and a reference page.

I will pay for the following article Improving Verbal Working Memory. The work is to be 6 pages with three to five sources, with in-text citations and a reference page.

Referring to Elizabeth (45, 67), memory entails three main chronological processes which are encoding, storing, and retrieving. Working memory can also be referred to as short-term memory is the memory that is usually in use at a given particular period in time. If one attaches meaning or significance to whatever he/she would be thinking about, then it will be transferred to long-term memory but if otherwise, then whatever the person was thinking about would not be stored for future retrieval and use.

To sum upon the definition of terminologies, verbal working memory is a subcategory of the working memory which is used to refer to the quantity of oral information that the brain can retain and employ in the achievement of a given goal or in finding a solution to a given problem. This kind of memory, however, bears more meaning than just the mere ability to recall information. it is also used in the processing of information and in deciding the kind of information required to handle a particular task, Milton (221).

Concerning brain imaging techniques, researchers found out that various processes that relate to verbal working memory occur in the prefrontal cortex’s left hemisphere. Most of the spoken/oral information is retained and processed in the left hemispheric cortex’s Broca’s and Wernicke’s areas. The former is used in the controlling of both grammar and syntax whereas the latter is used in the controlling of content and comprehension. This assumption was arrived at after testing the adults.

Children were avoided considering that language children do not possess a fully localized language.The phonological loop is one of the simpler forms of this kind of memory. In this form, there is a continuous repetition of some words or short phrases within a short period of time. This form may comprise information that was received or planned original utterances referred to as sub-vocal rehearsal. A good example of received information can be seen where one has been sent to go and purchase several items.

The person repeats these items repeatedly as he/she continues to&nbsp.look for a piece of paper to note them down.
