The Slasher Film The Modern Day Fairy Tale - 2034 Words

The Slasher Film: The Modern Day Fairy Tale General Purpose: To inform the audience about the psychological appeal of the slasher film, a brief history of the genre, and the links to urban legends and fairy tales. Specific Purpose: To inform the audience about direct link to morality tales and the slasher film genre. Thesis Statement: Slasher films are modern day morality tales, rooted deeply in urban legends and fairy tales, as clearly depicted in John Carpenter’s Halloween, where characters are punished with violence for their risky behavior. I. Introduction A. When asked to describe the two types of horror films, director Guillermo del Toro stated: â€Å"Much like fairy tales, there are two facets of horror. One is pro-institution, which is the most reprehensible type of fairy tale: Don t wander into the woods, and always obey your parents. The other type of fairy tale is completely anarchic and antiestablishment†-Guillermo del Toro. (Attention Getter) In my presentation I will focus on the aspect of the slasher film genre as modern day fairy tales, with an underlying message of morality. B. John Carpenter’s 1978 film Halloween epitomizes the slasher films, encompassing the most common themes of this genre, including teenagers making the transition into adulthood by engaging in reckless behavior, a maniac using violence as a teaching tool for the audience, a final survivor girl, and an immortal maniac. (Thesis) C. In my presentation I will briefly describe the history

How Does The Fever Affect Their Bodies - 1272 Words

Introduction This semester we discussed many things within the human body. We learned about many different systems of the body, such as the muscular system, urinary system, lymphatic system, cardiovascular system, nervous system, and the reproductive system. When studying all of these systems, we would look into different diseases or illnesses that could affect each system. Different illnesses affect different parts of our body in many ways and can be life threatening in many situations. In Fever 1798 I read how the fever affected their bodies, their ways for treatment, how they reacted, and more. Topic 1 How did the fever affect their bodies? In Fever 1798 by Laurie Halse Anderson, an epidemic known as yellow fever spreads throughout†¦show more content†¦During the time of this epidemic, no one had even invented the stethoscope or thermometer. Out of all of Philadelphia about eighty people were practicing medicine when fever began to spread and some of them weren’t even trained doctors. Doctors across Philadelphia were battling each other in a sense but they were mainly divided into two groups. One group was the people that followed Dr. Benjamin Rush and the others followed Dr. Jean Deveze. Dr. Benjamin Rush’s idea for treatment was to give his patients mercury, calomel, and jalap so that it would cause them to throw up and have diarrhea. He also drained blood from them in hopes of getting rid of the disease. Many medical experts believe that he probably killed many of his patients from doing these things. Dr. Jean Deveze and other French physicians proved to h ave the better methods. They prescribed rest, fresh air, and lots of fluids. These very things are still considered some of the best ways to cure the disease now. Besides these two methods, people in Philadelphia were trying anything and everything they could to prevent or cure yellow fever. They soaked sponges in vinegar and would put the sponges up their nose. They washed themselves and their clothes in vinegar and would drink the vinegar as well. People would fire guns and cannons in the middle of the streets hoping the gunpowder would clean the air. They chewed garlic and drank vile potions of herbs. They would even bury their

Wireless Sensor Networks Introduction to CDMA

Question: Discuss about the Wireless Sensor Networks for Introduction to CDMA. Answer: What does an amplifier do and why is one needed in a radio system? An amplifier is mainly an electronic component that can boost an electric current or some signals. Amplifiers are primarily used to amplify signals like let just say someone has hearing aid, the machine takes the sound all around the surroundings and then just increases its strength; this process is called amplification. Amplifiers are just known to amplify weak signals too strong signals. Amplifiers are the best option to regain a particular signal that is lost during the transmission (Freeman, 2007). It catches the signal, regenerates the actual signal and sends it to the receiver. Use of amplifiers is the most common thing in the case of transmission. Modulation-Demodulation, Coder-Decoder use amplification in each and every occasion. As a whole, it can be considered that amplifiers are mainly there to regenerate the lost signal so that efficiency of the sender and satisfactory level of the receiver are maintained. An amplifier can be used in radio systems very efficiently. It is mainly the modified amplifier that generally magnifies the high-frequency signals. It is used in radio system. The frequency in which the large number of improvement occurs in a particular radio frequency (known as RF) amplifiers are made of inconstant by frequently changing the capacitance as well as the inductance of a, particularly tuned circuit (Hussain, 2005). The request of amplification is very typical like firstly it receives the signal from the antenna earlier it is assorted with the local noise signals. The primary detector of the radio receiver receives the signal at first. The amplifier which is followed by the detector is a particular type of amplifier called the immediate frequency amplifier. The primary justification of rf amplifier can be done through its tuning ability over the assigned input frequencies. The shunt capacitance is mainly causes a problem for the improvement of a resistance-capacitance j oined amplifier. Then it turns out to be the portion of the tuning capacitance in the amplifier. In this way, the high gain at radio frequency is permitted. The above description tells us the clear picture about the use of an amplifier in the radio system. The range of frequency of a radio system is mainly restricted and after receiving the signal from the antenna, many noisy signals can be attached to the primary signal that can cause a problem. Then the rf amplifier and if amplifier comes into play (Feucht, 2010). The detector also plays a vital role in it. What is the purpose of a mixer? Include a discussion of sidebands in your answer. Mixer A mixer is an electronic device. It is mainly used to combine, changing and routing the volume level. It also combines the dynamic and timbre of several audio signals. For example, Microphone can be used by singers as well as mics can be used in acoustic instruments. For example, mics are used on drums as well as saxophones. The mixer can lead an essential role to transmit signals from electric as well as electronic instruments (Mangeot, 2005). Electric bass, the synthesizer is an example of such electric instruments. Analog and digital signals can be controlled by Mixer from 2010. It depends on the type of the mixer. A combined output signal can be produced by the summation of the modified signals. The signals are broadcasted by the user through a sound reinforcement system. The mixer can be used in several applications. The application includes several recording studios, sound reinforcements system, dance clubs, nightclubs, film production and television. The combined signal of two microphones can be combined by a typical application. The signals are transmitted to an amplifier which controls one pair of signal concurrently (Liu, Zhang and Yang, 2012). In the case of live performance, the signal which transmitted from the mixer goes directly to the amplifier. The amplifier must be plugged into the cabinet of the speaker. There are only two channels are provided in DJ mixer. It mixes two recording player. The mixer can also provide phantom power in capacitor microphones. It also provides pain control for changing the position of sound control. The mixer can also play an essential role for filtering and equalization. It can be the primary purpose of a mixer. It activates the sound engineer who boosts the sound frequency as well as cut the sound frequency to develop the quality of the sound. Mixer mainly uses in the digital processing techniques to attach three different input audio signals into one single output audio signal. It also manipulates every input signal modulation. It also maintains the high and low pass filters in its each audio channel independently. A mixer mainly provides the ability to observe each audio signal channels without providing any master output. A single, equalized and mixed signal can be obtained by the user from three different audio input signals. It provides an important role for mixing two songs as well as combine instrumental tracks together and create a passage of complex music. Sidebands IQ To identify the process for maximizing the information transmission, it is crucial to introduce IQ mixers. It allows user for modulating the in-phase as well as quadrature components of career concurrently (Edlich, 2013). It uses for the multiplexing of two modulating signals. Block Diagram Fig: 1 Sources: https://www.markimicrowave.com/blog/2013/06/iq-image-reject-and-single-sideband-mixers/ IR and SSB Image reject mixer can be used to allow a user to catch a signal in the crowded environment. It is overpowering the adjacent image signal. Image request mixer is also responsible for releasing the requirements of receiver filter. The single sideband mixer is mainly used to allow a user for up converting to a signal; it up-converts the signal into a career while overpowering frequency signal of the similar image (Archer, 2006). It is also responsible for releasing the requirements of the transmission signal. Fig: 2 Sources: https://www.markimicrowave.com/blog/2013/06/iq-image-reject-and-single-sideband-mixers/ Compare and contrast the multiplexing techniques CDMA and FDMA in the area of wireless networking? CDMA CDMA mainly refers to the fact of conversion of analog-to-digital signals. It is mainly done with the help of the spread spectrum technology. In this case, audio input is mostly manipulating into binary elements. It helps the receiver to follow the exact transmitter frequency (Abu-Rgheff, 2007). The CDMA channel normally has a range which is 1.23MHz wide. The Soft handoff scheme is used by CDMA networks that minimize signal fragmentation as a receiver which passes from one to another cell. The perfect mixture of spread spectrum modes as well as digital methods which support additional times as numerous signals per unit bandwidth as the analog modes. The nationwide roaming facility is provided by this technique as CDMA is companionable with the different cellular machineries (Engels and PetreÃÅ' , 2006). CDMA One is known as the original CDMA standards. A transmission speed of up to 14.4 Kbps can be offered by CDMA on its single channel. It can afford a capacity of 115 Kbps in an eight channel form. It is also to be notified that CDMA2000 as well as Wideband CDMA which send data as many times quicker. Working principle of CDMA: Unlike FDMA, CDMA separates calls by codes where each and every particular bit of a discussion is marked with a particular as well as unique code. In this process the system receives a call then it assigns the particular unique code in that specific conversation. Then the data is divided into minor parts as well as tagged with the exclusive code given to that specific conversation of which they are the parts of. After this part, the data is sent through some frequencies which are available to use at any specific time in a particularly mentioned series. At the end of the transmission, the receiver then recollects or regathers the codes to gain the actual message or data or signal. The technique of CDMA is mainly based on the separation of codes. That differs CDMA from FDMA. FDMA FDMA is standing for Frequency division multiple access. It is mainly the channel manipulation method through which multiple admittance protocols are used in a network. A unique allocation or different frequency can be sent to the user by this multiplexing technique (Koo et al., 2002). FDMA is used for wireless and satellite communication. It also co-ordinates the uses among several users. This technique mainly allocates for the wireless cellular phones. Here FDMA technique communicates into 30 channels. Working Principle of FDMA In FDMA, almost maximum users share frequency channel as well as the satellite transponder. But only every user transmits the signal at a single frequency. Every channel can contain digital service as well as voice conversation. It also carries digital data. In AMPS (Advanced Mobile Phone Services), FDMA leads a primary role to give better services. Here every channel can be assigned to one single user at the same time. That is the primary function of FDMA. FDMA is also be used in the TACS (Total Access Communication System). Unlike CDMA, in FDMA all channels are in an idle state when not in use. The bandwidth of the communication channel is comparatively narrow. It is also known as Narrowband system. To spread the symbol time, there is no need of equalization in FDMA. In this technique, analog signals can be most suitable. Also for continuous transmission, there is no need for synchronization. In the case of duplexing, FDMA combined with FDD. It is based on the separation of frequency. References Abu-Rgheff, M. (2007).Introduction to CDMA wireless communications. Amsterdam: Academic.

The fun filled fractal phenome Essay Example For Students

The fun filled fractal phenome Essay The Fun Filled Fractal PhenomenonA fractal is a type of geometric figure. It is generated by starting with a very simple pattern such as a triangle and, through the application of many repeated rules, adding to the figure to make it more complicated. Often, an input will be entered into a recursive function and it will yield an output. This output is then inserted back into the function as an input and the process is repeated infinitely. Fractals often exhibit self-similarity. This means that each small section of the fractal can be viewed as a reduced-scale replica of the whole. Some famous fractals include Sierpinskis triangle, Kochs snowflake and the length of a coastline. Fractals were brought to the publics attention by the work of French mathematician Benoit B. Mandelbrot in the 1970s. Mandelbrot discovered how to calculate fractal dimensions. The formula for fractal dimension is N=2D where N equals the number of copies of the original figure, which is calculated by doubling it s size and D is the dimension. Mandelbrot named his creations fractals because each part is a fraction of the whole figure. The Chaos Theory describes the complex and unpredictable motion of systems that are sensitive to their initial conditions. Chaotic systems follow precise laws but their irregular behavior can appear to be random to the casual observer. For example, weather is a chaotic system. If the rays of the sun bounce off the hood of a car in a certain way, causing a breeze, the breeze could blow a leave off a tree, which starts a series of additional events that could alter the weather in some other part of the world. Chaos can be related to fractals. In a fractal if one tiny change occurs in a repeated pattern, the entire fractal will change. The above picture is an example of a strange attractor that charts the trajectory of a system in chaotic motion. It is a fractal. The fractal exhibiting chaos is predictably unpredictable. This is because, in a chaotic system, it is predictable that there will be minute changes that will alter the entire shape. We will write a custom essay on The fun filled fractal phenome specifically for you for only $16.38 $13.9/page Order now Kochs snowflake, (above ) exhibits the concept of an infinite perimeter with a finite area. Kochs snowflake is created by dividing each of the sides of an equilateral triangle into three equal parts. Next, the center part of each side is taken out and replaced with two sides of equal length to that of the original centerpiece. This pattern is repeated infinitely. Each time the process is completed the perimeter gradually increases to infinity by increments of 4/3. However, the area of this snowflake is finite. If you draw a circle enclosing the original triangle that contains the vertices of the triangle, the area of the snowflake will never exceed the area of that circle no matter how many times its perimeter increases. Therefore, it has a finite area. Fractals exhibit self-similarity. This is the concept that each small portion of the fractal can be viewed as a reduced-scale replica of the whole. For example, in Sierpinskis Triangle, each small triangle inside is similar to the lar ge one on the outside. A real life example of self-similarity is a tree. The tree has a trunk on which limbs grow. Branches grow from the limbs, and twigs grow from the branches, which is followed by sticks on the twigs and so on. The sticks growing on the twigs are just a smaller version of the twigs growing on the branches, which are a smaller version of the branches growing on the limbs, which are a smaller version of the limbs growing on the trees. Another example is a universe, which is composed of a collection of spinning galaxies, which are composed of a collection of spinning solar systems which is a collection of spinning plants and so on. Each step is self-similar to the universe. Finally, a cloud exhibits self-similarity. A cumulus cloud is a collection of smaller puffs, which, in turn, are a compilation of smaller puffs and so on. Each puff is a smaller replica of the large puff. Fractals are often formed by an iterative process. That means that an operation is preformed on one figure to create a new figure. Then this operation is performed on the new figure to make another figure and so on. Each step of this process is called an iteration. An illustration of this is the diagram of Kochs snowflake on page two. It begins with a triangle Then an operation is performed on it and it becomes the Star of David. As the operation is repeated infinitely on the figure, it becomes an increasingly complex snowflake. Once a fractal, such as Sierpinskis Triangle, is created it is crucial to find out its dimension. The dimension of this fractal is greater than a line and less than a plane, so it is between 1 and 2. To find the exact dimension, one needs to follow a simple formula: The dimension (d) of a shape is the log of the number of copies (n) that are produced when the figures sides are doubled, divided by the log of 2 (logn / log2 =d or n=2d). The dimension of Sierpinskis Triangle would be the Log of 3, because you get three copies of the triangle when you double its sides, divided by the Log of 2. The final dimension is 1.58496250072115618145373894394782. .udf46d80821b12f4e5b58eef4f9557524 , .udf46d80821b12f4e5b58eef4f9557524 .postImageUrl , .udf46d80821b12f4e5b58eef4f9557524 .centered-text-area { min-height: 80px; position: relative; } .udf46d80821b12f4e5b58eef4f9557524 , .udf46d80821b12f4e5b58eef4f9557524:hover , .udf46d80821b12f4e5b58eef4f9557524:visited , .udf46d80821b12f4e5b58eef4f9557524:active { border:0!important; } .udf46d80821b12f4e5b58eef4f9557524 .clearfix:after { content: ""; display: table; clear: both; } .udf46d80821b12f4e5b58eef4f9557524 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .udf46d80821b12f4e5b58eef4f9557524:active , .udf46d80821b12f4e5b58eef4f9557524:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .udf46d80821b12f4e5b58eef4f9557524 .centered-text-area { width: 100%; position: relative ; } .udf46d80821b12f4e5b58eef4f9557524 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .udf46d80821b12f4e5b58eef4f9557524 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .udf46d80821b12f4e5b58eef4f9557524 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .udf46d80821b12f4e5b58eef4f9557524:hover .ctaButton { background-color: #34495E!important; } .udf46d80821b12f4e5b58eef4f9557524 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .udf46d80821b12f4e5b58eef4f9557524 .udf46d80821b12f4e5b58eef4f9557524-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .udf46d80821b12f4e5b58eef4f9557524:after { content: ""; display: block; clear: both; } READ: Mummification EssayThe human body is composed of many fractals. From the moment of fertilization, the cells of the egg and the sperm break up into two more cells, which, in turn, break up into two additional cells and so on. Each cell is self-similar to the entire collection of cells. This compilation exhibits the chaos theory. If one link in this collection is incorrect or missing, the entire organism can be ruined. It will collapse on itself creating a sickle cell. Some Africans have a disease called sickle cell anemia in which their blood cells have one bad amino acid chain in a protein of many hundred amino acids. These sickle cells clot and create a lot of pain for th e person afflicted with this disease. A body as a whole is a fractal. It is a group of dissimilar systems working together, which are composed of groups of dissimilar organs working together, which, in turn, are composed of groups of dissimilar tissues working together, which is a group of dissimilar cells working together, which is a group of dissimilar organelles working together. The body begins with the creation of cell organelles that are formed together to make a cell. These cells, as stated above, duplicate to form tissues, which duplicate to form organs and so on until a human body is conceived. Fractal research can be used to predict how complicated organ systems in the body will respond to changes. This is important for understanding how to treat diseases.
