Biography Of Andrew Jackson s Role Of Rebuilding The...

Mary Barukh Mr. Mutz U.S. History/ Block G 15 December 2015 Fall Final: 75 Years in the Making; 1865- 1940 Hello America, I have been a part of this great nation for 80 years. From the time I took my first breath as a baby to this exact moment of 1940. Over the years, I have traveled to experience and witness life changing events. Due to my past, I have gained a true sense of what it means to be an American. And believe me, America is something to be proud of. When I was little, Andrew Jackson was president. He took Abraham Lincoln’s role of rebuilding the South when he was assassinated. Even though America was morning the loss of Lincoln, Jackson stepped up. In May of 1865, he made an announcement about his plans for the reconstruction. Jackson believed in the Union and in State Right’s. Under Johnson’s plan all the land was taken away from the freed slaves and were given back to the previous owner before the war. With his promised loyalty to the Union and paying off the war debts, he gave state governments permission to rebuild. This led to a series of the â€Å"black codes† law. This limited what freed slaved were allowed to do. A year later the Freemans Bureau and the Civil Rights Act was created to help freed slaves. This became the first Act to ignore the president’s veto. Four years later, Congress approved the 15th amendment. It promised that citizens cannot be denied the right to vote no matter t heir race, color, or if they were previously a slave. Due to the

The Rhetorical Force of Landscape Art Essay - 1502 Words

The Rhetorical Force of Landscape Art Why talk about a rhetoric of images? The most obvious answer is that we live in an image-saturated society and a relevant rhetoric must pay attention to images, that W. J. T. Mitchell is right when he suggests that the rhetorical turn is being displaced by the pictorial turn. Beyond the obvious, the answers are multiple and layered. I want to suggest some answers by looking at some old pictures: Carleton Watkins landscape photographs of Yosemite and William Henry Jacksons landscape photographs and Thomas Morans water colors and paintings of Yellowstone. At a basic level, if rhetoric is, at the very least, about persuasion in conventional politics, images merit a look and have†¦show more content†¦Moran and Jackson accompanied the U.S. Geological Survey of the Territories to Yellowstone in 1871. Their presence was not accidental. Jackson had recently become a permanent member of the expedition. Moran was sent with the backing of the Northern Pacific Railroad and Scribners to join the expedition. Ferdinand Hayden, the expeditions leader, was aware of the value of public relations and was also under orders from the Secretary of the Interior to secure as full material as possible for the illustration of your final report, such as sketches, photographs, etc.,(quoted in Kinsey, 1992, p. 49). As photographer Jackson recalled, No photographs had as yet been published, and Dr. Hayden was determined that the first ones should be good. A series of fine pictures would not only supplement his final report but tell the story to thousands who might never read it (1940, p. 196). Jacksons photographs and Morans watercolors and illustrations were instrumental in the successful lobbying effort to get Congress to designate Yellowstone the countrys first national park. More significantly, I contend that the landscape art of Watkins, Jackson, and Moran are not merely evidence in a conventional political argument. They are not simply representing reality or making an argument aboutShow MoreRelatedAnalysis Of The Poem Wild Swans At Coole 1004 Words   |  5 Pagesthe increasingly complex form of his poetry which challenges existing perspectives on mortality as well as philosophy on beauty and art in order to find new ways of perceiving the world.

Write a Short Describing the Role of Nutrition free essay sample

The process of digestion seems deceptively simple, matter moves into the body and continues down a conveyer belt like chain of organs that break it down completely before it leaves the body. However, the maintenance of such a system is complex and relies on a balance of pH and helpful bacteria to maintain homeostasis. Both acidic and basic pH’s are required at various points in digestion to maintain balance during the process. Saliva in the mouth, the starting point of digestion, is only mildly acidic for the purpose of initially breaking down the food without damaging the teeth or delicate throat tissue. The stomach, on the other hand, needs to be highly acidic to jump-start the breakdown process as well as act as a defense for the body against any harmful bacteria or other intruders. To balance things out on the basic side, it is important that the small intestine has a high pH, because most of the enzymes used in digestion cant function properly in an acidic environment. Helpful bacteria also are integral to maintaining homeostasis in the digestive system. It is estimated that the average human has around 500 species of helpful bacteria, also known as intestinal microflora, in the digestive tract, mostly concentrated in the large intestine. These bacteria aid in digestion, help produce vitamins, help formulate excrement and guard against harmful bacteria. When the bacteria population in a digestive tract is thrown off or decimated, the host will notice a change in the pace and quality of digestion. Microflora species have such a positive effect on their host that there are many products available, mostly yogurts, that contain material that supports intestinal microfloras growth and health. Homeostasis is a condition by which the biological / physical body is not lacking any nutrients and all needed nutritional components are readily available in their proper forms and amounts so every biological function can operate unimpeded. When various nutrients are lacking, some bodily functions will be undernourished. The essential bodily functions will receive their proper nutrients first so life can continue. Non-essential bodily functions will then suffer due to lack of all nutrients needed for their full function. Examples of non-essential bodily functions are: hair, skin, sexual function, muscles, tendons, vertebral discs, etc. Examples of essential bodily functions are: heart, lungs, kidneys, liver, etc. After the body has received all the nutrients it needs for the essential bodily functions, then the non-essential complaint receives its needed nutritional components and those complaints will usually resolve on their own. Water is essential to life and nutritional health. Humans can live for several weeks without food, but can survive only a few days without water. Water makes up a large percentage of the body, in muscles, fat cells, blood and even bones. Every cell, tissue and organ requires water to function properly. Water transports nutrients and oxygen to the cells, provides a medium for chemical reactions to take place, helps to flush out waste products, aids in maintaining a constant body temperature, and keeps the tissues in the skin, mouth, eyes, and nose moist. The body does not store excess water like it does with other nutrients. With physical exertion, water requirements increase; therefore, fluid replacement during exercise is critical. The longer the duration and the more physical exertion athletes put into their exercise, the more fluid they lose during workouts. To keep the body working at its best, it is essential to replenish lost fluid after workouts, and to stay well hydrated during exercise. The body can accommodate extreme changes in water intake when the brain and kidneys are functioning normally. It is usually possible for a person to consume enough water to maintain blood volume and electrolyte balance in the blood. However, if a person is unable to consume enough water to equal excessive water loss, dehydration may result. The body works to maintain water balance through mechanisms such as the thirst sensation. When the body requires more water, the brain stimulates nerve centers in the brain to encourage a person to drink in order to replenish the water stores. The kidneys are responsible for maintaining homeostasis of the body water through the elimination of waste products and excess water. Water is primarily absorbed through the gastrointestinal tract and excreted by the kidneys as urine. Water intake can vary widely on a daily basis and is influenced by such factors as: access to water, thirst, habit, and cultural factors. The variation in water volume ingested is dependent on the ability of kidneys to dilute and concentrate the urine as needed. There is a reservoir of water outside of the bloodstream that can replace or absorb excess water in the blood when necessary. The following conditions increase water consumption needs. However, the amount of water necessary depends on body size, age, climate, and exertion level. Water needs are increased by; Exercise, High altitudes, Prescription drugs, Dieting and Illness. Individuals should not wait until they are thirsty to replenish water stores. By the time the thirst mechanism signals the brain to encourage a person to drink water, already 1–3% of the body fluids are lost and an individual is mildly dehydrated.

Security And Privacy Of Biometric Recognition

Question: Research into the different types of biometric systems which are currently available for access control systems. Briefly describe the techniques and technologies used for each type and discuss the advantages and disadvantages for the three types below. Give an example application when each type could be used. Answer: The biometric sensors or the gain access to control systems usually are classified into two kinds these are physiological Biometrics and the Behavioral Biometric.The physiological biometrics might include the following; face recognition, palm and gait recognition as well as the Iris recognition (Myers, 2017, pp. 43). On the other hand the behavioral biometric include the signature, voice recognition. Physiological biometrics Palm and gait recognition When it comes to the palm recognition there is a three dimensional image of the hand which is collected and compared to the stored sample. This device performs a great amount of the identification within a short time. These technologies are installed in the situations where there is a large number of individuals such as the airports (Prabhakar, Pankanti Jain, 2003, pp. 33-42). On the other hand this technology is expressed not only by the way an individual looks or sounds, but also the manner in which a person walks. The technology is applied to moving perambulatory subjects. This technology is useful especially in the surveillance (Ross Jain, 2004, pp. 134-145). Advantages They could be utilized in a range of the environment. They can perform a great amount of identification within a short period of time (Ross Jain, 2004, pp. 145). Disadvantage The performance of the technology could deteriorate over time. They have the added difficulty of having to sample and identify the movement especially for the gait recognition. Face recognition This kind of biometric computer application that is capable of identifying as well as verifying a individual from the digital image through comparing as well as analyzing the patterns. These kind of biometric systems are used in the security systems (Prabhakar, Pankanti Jain, 2003, pp. 33-42). The application works with the face prints and the systems are capable of recognizing 80 nodal points on the human face. Advantages The technology is capable of searching against the static image such as the driver license or even the passports. It is the only biometric which is capable of operating without the cooperation of the user. Matching of the accuracy is reduced as a result of the acquisition environment. Disadvantages Matching of the accuracy is reduced as a result of the reduced changes especially in the physiological aspects. Most of the devices are unable to enroll some percent of the users as well as performance could be deteriorated over time. Iris recognition In this kind of bio-metric the method used in identifying individual depends on the single patterns in the region of the ring shaped encircled the pupil of eye (Prabhakar, Pankanti Jain, 2003, pp. 33-42). Furthermore, it includes a blue, gray or brown color with the hard patterns which are recognizable when one looks closely. Advantages There are high levels of accuracy with this biometric This biometric technology can maintain stability of the features over some time. Disadvantage The disadvantage of iris biometric is that it has a propensity for the false rejection. The acquisition of the images entails some moderate attention as well as training. Behavioral Biometric Voice recognition This is a technology that is utilized to produce speech patterns via combining both behavioral along with physiological aspects which are captured through processing the speech technology. The significant properties that are utilized to authenticate the speech is the nasal tone (Ross Jain, 2004, 140). This biometric could be separated into the various categories based on the type of authentication domain such as fixed text method, text independent method or even the conversational techniques. Signature recognition This type of biometric method is used in analyzing as well as measuring the physical activity of signing the pressure utilized, the order of the stroke and the speed. A number of the biometric are utilized to review the visual images of the signatures. This biometric might be operated into alternative ways for example the static and the dynamic. Advantages and disadvantages of the biometrics Advantages Increased security: Biometric technology could offer a higher degree when it comes to the security as compared to the other traditional authentication methods. Increased convenience: the use of the biometric authentication allows higher levels of the rights and the privileges with a much success to the authentication (Myers, 2017, pp. 49). They allow an increase convenience since they can protect the data without any need for the human intervention. Increased accountability: the deployment of the biometric application to secure access to the computers as well as other facilities eliminate any occurrences such as the buddy punching, thus offer a higher level of certainty on who to access the system. Disadvantages There is tendency of privacy abuse due to the non-cooperative enrollment as well as identification capabilities. (b) Privacy-enhancing technologies (PETs) used on the Internet Communications anonymizers: These technologies usually hide the real online identity such as the IP address and the email address and then replace them with the non-traceable identity. These technologies could be applied to the email, web browsing, as well as the instant messaging. Enhanced privacy ID: It is a digital signature algorithm supporting anonymity. It provides a typical grouping public verification crucial related to lots of the unique private signature keys. The application was made to permit prove a device to the external party what type of the device it is without necessary revealing the exact identity. Access to personal data: This service providers provides the infrastructure that allows the users to inspect, correct or perhaps remove all the data that is stored at the service provider. Different types of threats and vulnerabilities which can be used to attack the WSN Denial of service attack (DoS) These occurs when the attacker continuously bombards the Access point which is targeted or even a network with the bogus requests, failure information, as well as the commands (Alam De, 2014, pp. 67). DoS attack is an event which diminishes or even eliminate the capacity of the network in performing the expected function through the failures of the hardware, bugs in the software, exhaustion of the resources, as well as the malicious transmitting of the higher energy signals . The communication techniques could be jammed entirely in case such attacks might be successful (Lupu, Rudas, Demiralp Mastorakis, 2009, pp.54). Other denial of the services attacks is much possible such as inhibiting communication through the violation of the MAC protocol (Lupu, Rudas, Demiralp Mastorakis, 2009, pp. 59). These might result in authentic end users to manage to get to the network and might cause the network in crashing (Ghildiyal, Mishra, Gupta Garg, 2014, pp. 1163). This attack generally rely on the abuse of the protocols for instance the Extensible Authentication protocol. How to mitigate the threat The technique which is used to prevent this attack includes the payment for the network resources, push back as well as a strong authentication along with the identification of the traffic. Moreover, there are some other techniques which are used in securing the reprogramming process such as the authentication flows (Lupu, Rudas, Demiralp Mastorakis, 2009, pp. 65). The choice for the DoS is to rekey the request packet. Therefore, it comes from the node only when two consecutive keys have been invalidated or lifetime of the key has expired. Sybil Attack: Wireless sensor network is vulnerable to the Sybil attack. In this case the node could be more than one node which is utilizing various identities of the legal nodes. A given single node could present multi identities to the other nodes which are in the network (Lupu, Rudas, Demiralp Mastorakis, 2009). Sybil attack it tries to degrade the integrity of the data, security as well as the utilization of the resource which the distributed algorithm attempts to achieve. Figure 1: The diagram show the Sybil attack How to mitigate the vulnerability This vulnerability could be mitigated through authentication as well as encryption mechanisms which prevent the outsiders from launching the attack to the wireless sensor networks (Ngo, Makihara, Nagahara, Mukaigawa Yagi, 2014, pp. 228-237). Moreover, the use of the public key cryptography could be used to avoid the insider attack. This method could be very costly especially to the resource constructed sensor networks. Identities need to be verified through use of the public key cryptography (Fragkiadakis, Angelakis Tragos, 2014, pp. 78). Other ways to prevent the vulnerability would be through use of the radio resource testing, verification of the key sets especially to the random pre-distribution of the key and the registration and position verification particularly in the sensor networks. Software attacks When it comes to the software program dependent attacks on the WSNs, the attacker might try making adjustment to the software code in the memory or perhaps exploiting the known vulnerabilities when it comes to the code of the software (Galbally, Marcel Fierrez, 2014, pp. 710-724). Example of a well known attack is the buffer overflow attack. In this attack the method attempts to store the data beyond the boundaries of the set length of the buffer, therefore results to overwriting extra data on the adjoining locations of the memory. How to mitigate the vulnerability/threat There are various countermeasures which could be employed to secure the WSN software and prevent it against software attacks they are follows: Authentication and validation of the software through remote software based attestation especially to the sensor networks. Defining accurate trust of the boundaries to the various components and users. Utilizing of the restricted environment for example the Java Virtual Machine (Rao, Rai Narain, 2017, pp. 4-8). Attestation of the hardware: It is the trusted computing group platform as well as the next generation acquire computing base that provides this kind of attestation. A more equivalent model might be utilized in the sensor networks (Kumar, Jain Barwal, 2014, pp. 859-868). Dynamic runtime encryption and decryption for the software program. This really is much like encrypting or even decrypting the data except that the code is running on the device which is being decrypted (Wu, Ota, Dong Li, 2016, pp. 416-424). This could prevent any kind of malicious user from exploiting this particular software. References Alam, S., De, D. (2014).
