This goal is positions exceptionally high among the top goal for sightseers because of its staggering and world well known trekking courses of Annapurna and voyagers take resting days in Manang before the treks to adapt to the height (Reynolds 2015). The zone was shut to outsiders till 1970.the universes most noteworthy arranged Lake Tilicho Lake is a star fascination for traveler going to Manang.

Pain Poem

Torment Innocent tufts out of the desolate seed, Illusion of murkiness was seen, Things seen were assimilated, Sun, water, alert what was the deal? Fell in a passage, Lights were not yet observed, Faith gradually got frail, Failings, it would be ideal if you stops Dodge, safeguard and assault like a fighter, Easy beginning yet harder comes, Not a solitary squint of an eye, Be firm and don't relax up a solitary muscle! Load up with every single splendid shading, Four brilliant hues more than one dim shading, Darkness was concealed at this point splendor was plainly observed, This is the thing that the world should be! Strolling on a dim street,Rusted road light soul working, Street light can't yet road lights can, Street is dull no more yet now splendid. Rundown Answer Pain, directly as of now sincerely I can't consider whatever causes me to feel torment. I don't think I have experienced the profound agony that individuals can't dispose of, however there is one thing that causes me to feel torment and that is when see others in torment and to see this delightful world enduring with such a significant number of sorts of things.

Topics on Social Issues Today

Topics on Social Issues TodayWith the President's speech on the recent shootings in Texas, I had to go back and review some of my articles on some of the most politically charged topics on social issues today. Of course, the first one I read was why the President's speech was so important. The first thing you will notice is that almost all of the articles that I have written in this series of articles deal with the same issues and are published on the same topic.So I thought I would take a few minutes to write a short article about each of these topics. I tried to follow up with other issues such as immigration and health care in some of the other articles but I did not feel it merited a full article. Nevertheless, you will be able to find that information elsewhere.One of the best social issues today is abortion. Abortion has been an issue of contention for many years. At one time, the issue came down to the state's rights while now it is becoming increasingly national in nature. Wh ile it may not be that controversial of an issue anymore, its impact on the country cannot be underestimated. There are a few topics on the web where you can find the latest news regarding abortion.Another issue that is quite controversial is when a physician decides to terminate a patient's pregnancy based on the physician's choice. Many people support this practice but many others oppose it. We see the media make it very clear on a daily basis. It is also worth noting that if a person is involved in an accident during which a pregnant woman's life was threatened, it is legal for the woman to terminate her pregnancy. This is a highly debated issue.Another topic that seems to be quite controversial is whether or not someone should be able to refuse to provide services to a gay or lesbian individual based on their own personal beliefs. Some believe this to be the right thing to do while others disagree. Regardless of your opinion on this issue, it does not seem to be something that a nyone wants to be spending time discussing in front of the family and friends.Finally, one of the more liberal views is the view that homosexual individuals should be allowed to use the restrooms that they want. It seems that when a person uses the restroom, they should be free to choose to use the washroom that they feel comfortable using. Therefore, it seems that this is the only issue worth talking about. Personally, I disagree with this view but everyone is entitled to their own opinion.These are just a few of the topics on political issues that I have written about. It is safe to say that in many ways we see a continuous flow of political debates on these topics in addition to issues of civil rights, sexuality, race, religion, and immigration.With all of the battles that are being fought today it is hard to decide who or what is worth fighting for. However, the fact remains that it is important to understand that everything that is being discussed is politically charged. The tr ick is to keep a positive attitude in order to keep the water out of your eyes and stay focused on the big picture.

The Issue Of Privacy On Computers And The Internet

The argument â€Å"Nothing to hide, nothing to fear† states that as individuals we are entitled to privacy unless our private on goings involve illegal activities (Wikipedia). Conversely â€Å"Computers and privacy don’t mix† suggests that the concept of privacy is non-existent when using computers, due to the nature of computers themselves. Both statements feed into the issue of privacy on the platform of computers. This essay contends that privacy on computers and the internet is a complex problem due to the poor state the law governing it and privacy being misunderstood by society on the computer platform due to the infancy of the internet and computers and security issues that could be similarly regarded as part of problem to why computers and privacy don’t mix at this point in time and that even In order to discuss both arguments and come to an informed decision that is relevant to the topic, what privacy means must be considered.

Plato s Allegory Of The Cave - 1217 Words

Have you ever judged a person, an object, or even a place by what it looks like on the outside? Or maybe you have judged all of that just by what someone else has told you. Everyone in this world has either judged someone or something in their lifetime or has been judged. Many people out there in the world also believe they know many things and have tried to get the point across to someone and well, they just don’t believe them in any way. They believe there point of view is more right than the other persons and sometimes that can get a little out of hand, depending on who you are dealing with. I guess the major point in all this is to never judge a book by its cover, always learn yourself. In Plato’s â€Å"Allegory of the Cave†, there are these prisoners that live in a cave and have never seen any natural sunlight. They can only see shadows of things displayed on the wall by the light coming from the fire. The prisoners get happy and interested by the shadows th ey see. The shadows could be of humans, objects, animals, or even plants. They see them as real, whereas, we see them as just shadows. One day, a prisoner goes out into the real world. He is blinded by the sunlight, so after his eyes adjust, he realizes that the shadows that were being shown in the cave aren’t actually real and that all the real objects are outside of the cave. Objects like plants, colors of what the animals look like, animals, tree, and even stars.

Journal On Selected Areas In Communications -Myassignmenthelp.Com

Question: Discuss About The Journal On Selected Areas In Communications? Answer: Introducation RSA: This cryptographic algorithm was designed by Rivest, Shamir and Adleman in the year 1977. It is a public key encryption standard. This algorithm makes the use of large integer numbers. According to this algorithm an individual will use one public and one private key. The sender will use the receivers public key to encrypt the message that will result in cipher text. The receiver will be able to read the message by decrypting the message using its own private key (Jonsson et al., 2016). RSA has invented the concept of digital signature. This algorithm is based on the problem of factorizing the product of two different large prime integers or numbers. RSA is a secured cryptographic algorithm. DES: Data Encryption Standard is a symmetric key algorithm. It was developed by the research team of IBM. Same keys are used for the purpose of encrypting as well as decrypting messages. Two techniques called diffusion and confusion are used in DES. There are sixteen rounds present in DES (ISLAM AZAD, 2014). The confusion technique uses XOR operation. The size of plain text is 64 bits. The key size used here is 56 bits. The Triple DES is more secure than DES as the message is first encrypted then it is decrypted and again it is encrypted (Barker Barker, 2012). AES: Advanced Encryption Standard was developed after DES and Triple DES. It has a simple design and low cost of memory as compared to DES. The speed of this algorithm is higher than the other algorithms (Karthik Muruganandam, 2014). Size of the plain as well as cipher text is same. It is a symmetric algorithm and uses identical keys for encrypting and decrypting messages unlike RSA. Encryption is done by substitution, shifting and mixing of bits. The message block size used in AES is 128 bits and there are three keys. AES is gives better performance as compared to DES. Security Challenges of WPAN Technologies Security Challenges of Bluetooth Technology: Bluetooth technology allows several wireless devices to connect over a short distance. The mobile phone users can turn on the Bluetooth options in their phones and pair with another device in order to share files and other documents. There are several security challenges that exist in this technology. Malicious codes enter the devices through a file and affect the system. Viruses can damage the system and misuse the valuable information present in the device. Bluesnarfing attack accesses personal photographs and details in an unauthorized manner (Minar Tarique, 2012). When the attacker is able to pair with other devices for the purpose of misusing data then it is called Bluejacking attack (Padgette, 2017). Backdoor hacking is a technique where the attacker accesses the data of a system secretly and the victim remains unaware of this unauthorized access. The private area network created by Bluetooth technology is prone to various security risks and attacks. Incorporating strong security policies will help to prevent such attacks. Security Challenges in ZigBee: ZigBee standard is used in private area networks or PAN. Remote controls, home automation and many other services like the retail services make use of ZigBee. The main security challenge in ZigBee is that the encryption key can get hacked. Sniffing attacks can take place where a monitor or device is able to capture the data exchanges that are taking place in the network (Zillner Strobl, 2015). There are several nodes in the network and one of the nodes can hide its identity for the purpose of attacking the encryption key and the data packets (Wang, Jiang Zhang, 2014). Injection attacks are also possible in ZigBee as the protocols present in ZigBee are not strong. This makes it vulnerable to different types of risks and threats. Critical Reflection on Energy Harvest Energy harvesting focuses on deriving or producing energy form external sources like kinetic energy, wind energy, thermal energy and solar energy. Hydro energy also plays a major role in harvesting energy. Energy can be conserved by this technique of energy harvesting. The wireless networks can store and use the derived energy. According to Ulukus et al. (2015), the nodes present in wireless networks should have the capability to harvest energy on its own. This will enable the nodes and the wireless devices of the network to gain and generate energy continuously. The concept of energy harvesting will benefit the people of future generation. The energy consumption level will fall by adopting this method. A balanced or controlled procedure can also be used for harvesting energy. This will involve the use of human made sources. The efficiency levels of the technologies used will vary. Technical concepts and methods can be applied for harvesting energy continuously. According to Ulukus et al. (2015), Gaussian noise and AWGN channel concept can be used for harvesting energy. The output of this process is the sum of noise and input. Ulukus et al. (2015) presented a concept where the main focus was in the integration of circuits and devices for energy harvesting and transferring purpose. According to Shaikh and Zeadally (2016), WSN technologies have limited energy. Energy efficient and high performance devices can be used for reducing or minimizing this problem. There are two main sources of energy like ambient sources and external sources. Shaikh and Zeadally (2016) said that the ambient sources are the cheapest source of energy. External sources can be explicitly used for the purpose of energy harvesting. Solar based technique can be used for the purpose of harvesting energy where the solar energy is utilized. RF based or radio frequency based techniques can also be used. Wind energy and hydro energy can be used for the purpose of generating electrical power or electricity. Electricity can be generated by using turbines. Falling water can be used for the purpose of harnessing energy. Shaikh and Zeadally (2016) also said that Seebeck effect can be can be applied for converting heat energy into electrical energy. Digital Cellular Handsets Slide note: The Telestra Company is engaged in providing wired telecommunication services across Australia. Their aim is to implement an advanced wireless field of system. Slide note: Cellular handset is a telecommunication device that takes the help of radio waves in order to transmit data wirelessly (Goggin, 2012) Cellular handset is accessible to all and therefore, it would be very beneficial to use it for accessing and displaying standard PC documents.
