Frankenstein :: essays research papers

Mary Shelly’s Romantic novel Frankenstein was a momentous accomplishment in the area of writing. Not only was the author only twenty-one when Frankenstein, or The Modern Prometheus was published in 1818, but the author was a woman. She became a very profitable author even though she only wrote one book, Frankenstein, which is said to be the first science-fiction novel. Victor Frankenstein, the protagonist of the novel, can be seen as a man who is mostly good, or a man who is mostly evil. Victor Frankenstein was a man who was passionately and sincerely in love with science and the quest for knowledge, a man who had one deep aspiration, and a man who got in over his head.   Ã‚  Ã‚  Ã‚  Ã‚  Because Victor Frankenstein was so zealous about science and what it could do, and because he was so entranced by the thought of creating human life, he eventually does finds the secret of life and artificially ‘births’ the Creature. His plunge into the maniac-like state that consumed him was slow, and gradual, each day he became more and more distant from society.   Ã‚  Ã‚  Ã‚  Ã‚  Because Frankenstein spent years of planning and hoping to find the secret of life, he never thought that he actually might be frightened when he saw the creature for the first time. But, this is exactly what happened. Even though he knew what he was trying to do, when it happened, and he actually saw the creature standing there in front of him--he was terrified. So, acting on impulse, and fearing he might get hurt from this monstrous creature, he ran away from it.   Ã‚  Ã‚  Ã‚  Ã‚  When Frankenstein was sure that the Creature killed William, he still didn’t tell anyone because he knew it would be no use; no one would ever believe him. He knew that his admitting to creating the monster would be to no avail and thought that no good could come out of it.   Ã‚  Ã‚  Ã‚  Ã‚  The biggest support for Frankenstein being mostly good is illustrated in the novel when he decides to not finish making the female companion to the Creature. He was being extremely selfish throughout the book until this point, but this time, he actually thought about someone else besides himself.

Measurements and Error Analysis, #1, Chris Abaca Discussion of differences The purpose of this experiment Is to understand why we have variances In measurements and how to reduce the variances. When taking a measurement there are multiple factors that affect its value. The more the measurement is taken the measurements average is closer to the actual value. Other factors include the instruments calibration, cleanliness of the inside of the measuring arms and human error In reading the measurements off of the measuring devices. For this experiment, we followed the procedures as Indicated In the lab manual.There are 3 variables that we have to take into account for calculating the density of the copper rod. The length plays the largest role in the uncertainty of the copper rod's density since it has the largest deviation. The Fernier calipers were the most accurate because it showed the smallest deviation. Our experiment carried out exactly how the theory explained it would. We measure d the same part a multitude of times and received varying data. Calculating the density from the averaged data made the value more accurate, and when combined with the standard deviation; our values for density became that much more accurate.

Digital Signal Processing

The concept of digital signal processing has been widely used these days, as it has provided many benefits to the users with its capability of converting analog signals into digital signals to facilitate the process of transmission. The encoding techniques are available which were developed after a comprehensive research to support and enable the transmission of digital signals to meet the user requirements. Apart from that, the process of ramification of every signal into many frequency bands where ever band has been digitally encoded by itself is termed as sub-band coding. Furthermore, it is better to encode lower frequency band with more bits than the higher frequency bands because the lower frequencies hold most of the speech energy. Sub-band coding method is mainly used to solve this particular problem. This paper depicts the benefits and the importance of sub-band coding, as well as it explains the steps involved in performing sub-band coding.The method of sub-band coding has b een widely practiced for the purpose of transmitting digital signals. For efficient signal encoding this particular method has provided many benefits. Moreover, sub-band coding has also been used for many years in audio industry for high quality digital audio transmission. At first, there is only one signal available which is then subdivided in many numbers of smaller sub-bands where every single number composed of a fractioned spectral of the actual spectrum from that actual signal. This process of dividing signal into sub-band will further assist each band to be transformed through distinct number of bits for every sample, and further every single band is classified according to its step size. By performing the above process resulted in a finer signal quality (Proakis and Manolakis, 2007).After completing the above process, it will now be possible to encode every single band separately according to the following set of steps. The starting step of the digital signal processing is t o apply the filtering required for the signal, which might be a high pass or a low pass signal. The purpose of filtering is to avoid the noise linked with the signal. The frequency of noise associated with the signal can be high or low, depends upon the actual signal requirement. Apart from that, to reduce the sub-band sampling rates, filters are used to minimize the bit rate in the signal encoding process. This method helps to reduce the signal on every band from a factor of two in sampling rate, which suggests that every second sample must be taken from the signal in the process of digital signal processing (Crochiere, 1981).Furthermore, the above step can be elaborated as if the signal is x[0-6], the samples taken from this would be x[0], x[2], x[4], and x[6]. The major reason of sampling through this method is to make sure that the reduced number of samples which would be quantized based on the following phase, which makes the quantization step to be as efficient and as quick as possible.The next step includes the quantization of signal on each band. In this process of quantization involves quantization noise to all the bits that are going to be sampled. However, at the   receiving end, all those signals which are acquired from the process of quantization   are to be   sampled from the   factor of two. By doing this method if the input signal is x[0-6], the output signal would now results in x[0], x[2], x[4], x[6]. Through performing this step, the identical number of samples before down sampling would be obtained where every substitute sample was missing (Veldhuis, Breeuwer, and Van Der Wall, 1989).The following step in the process of sub-band coding is to apply filters on all signals located at every single band where every filter should be of similar type which are used in the previous steps. Moreover, all filters are now used to lessen the number of sub-band sampling rates. These signals already moved through the quantization and the up and dow n sampling stages which results in proper mode of decoding (Schaffer and Rabiner, 1973).The final step requires amalgamating the signals from many sub-bands to achieve the output signal and to produce an altered version of the input signal. The following equation shows that there is only one band available from the two bands that will move in the equivalent process.X1 (z) is the signal on the transmitting end, which was acquired after moving from the H1(z) also known as the high-pass filter which is:X1 (z)= x1 (0)+ x1 (1) z-1+ x1 (2) z-2+ x1 (3) z-3   Ã¢â‚¬ ¦_____ â€Å"1†X1 (-z)= x1 (0)- x1 (1) z-1+ x1 (2) z-2- x1 (3) z-3   Ã¢â‚¬ ¦_____ â€Å"1A†It is therefore proved that Z-transformed is actually a result of passing a high pass filter to the signal which is the actual input x[n]. X1 (z)= X (z) H1(z) _____ â€Å"2†The down sampling has been performed by the factor of two on the signal which is originally X1 (z) will now be presented by Y1(z) signal as show n in the following equation:Y1(z) = y1 (0)+ y1 (1) z-1+ y1 (2) z-2+ y1 (3) z-3 †¦_____ â€Å"3†Y1(z)   = x1 (0)+ x1 (2) z-1+ x1 (4) z-2+ †¦_____ â€Å"4†The equation â€Å"4† mentioned above, explains that the down sampling effect has removed every single alternate sample available.However, at the other end signals that were previously up sampled, will now be considered as U1(z) at which every single alternate sample is equal to zero value.U1(z) = u1 (0)+ u1 (1) z-1+ u1 (2) z-2+ u1 (3) z-3   Ã¢â‚¬ ¦U1(z) = y1 (0)+0+ y1 (1) z-2+ 0+y1 (2) z-4+ †¦U1(z) = y1 (0)+ y1 (1) z-2+ y1 (2) z-4+ †¦ from â€Å"4†Ã‚   U1(z)= Y1(z2)U1(z) = x1 (0)+ x1 (2) z-2+ x1 (4) z-4+ x1 (6) z-6 †¦U1(z) = (X1(z)+X1(-z))/2 = X(z) H1(z)+X(-z) H1(-z)/2__†5†Besides, the U1(z) signal now move towards the next high pass filter which is K1(z) which is positioned at the receiving point and specified as:V1(z)= U1(z) K1(z) =  ½ K1(z) [X(z) H1(z) )+X(-z ) H1(-z)] â€Å"6†Furthermore, the final output signal will now be created after each sub-band output is added which results in the subsequent equation:X_out(z)=V1(z)+ V2(z)X_out(z)=  ½ K1(z) [X(z) H1(z) )+X(-z) H1(-z)] +  ½ K2(z) [X(z) H2(z) )+X(-z) H2(-z)] .X_out(z)=    ½ [H2 (z) –H2 (-z)] X(z).When the final output is obtained, to make equation more expressive, it will now be altered into the frequency domain of w from the resulted Z domain, which will now be expressed in the following manner:X out(w)=  ½ [H2 (w)- H2 (w-p)] X(w).X out(w)= [e-jw(m-1) Hr2 (w) – e-j(m-1)(w-pi) Hr2 (w-p)] X(w).In the above equation, m represents that even number which measures the length of the filter.After completing the above procedure, the next phase requires experimentation which includes the implementation of sub-band coding that can be accomplished through two methods. The first method of experimentation is MATLAB, which requires the theory section to be followed from the same phases outlined. There is a file named as ‘subband.dat’ is provided from the input signal in this particular method. This file consists of many values which expresses the file regarding the capacity of the signal in a given time. Moreover, H2(z) was also given as the coefficients of the low pass filters (Croisier, 1974).It is also suggested that the high pass filters H1(z) are used with the low pass filters K2(z) which creates relationship among the filters explained below:H1(z) = H(z),   H2(z)= H(-z), K1(z)= 2H(z) and K2(z)= -2H(-z).Apart from that, there is one more value known as the SNR value that is required for the process of quantization where every single value of Q1 will be computed through the following equation:SNRdB=[ à ¥ xi(n)2 /   à ¥ (xi(n)- xo(n))2 ]. Where the limits of the summation is from n=0 to N-1.The next method for the implementation of the sub-band coding used is called C6711. It is a device that works as a converter and faci litate users in converting software implementations into the physical results. On the other hand, CRO is used on which the output will be connected for the verification of results. Moreover, the sine wave is also generated through connecting the frequency generator to the C6711 device (Rabiner and Gold, 1975).Finally, the results generated through MATLAB for the sub-ban coding reveals that before performing any find of modifications on the signal, it highly requires the plotting of input signal. Apart from that, result has also shown that the low pass and high pass filters of sub-bands were moved towards an intersection point which exactly equals to 0.5 rad/sample.The SNR values used in the process of quantization of distinct number of bits reached at a highest level of 16.5dB at the 5th bit. On the other hand, the SNR value has been calculated for 4 bit PCM system was almost 13.2dB. The value suggests that there is a 0.5dB variation from the value computed at the forth bit which is 12.7 dB and is acceptable after the comparison. However, the resulted output signal appeared on the CRO is quite similar to the input signal which explains that as the frequency increases the output signal will move towards zero (Kuester and Mize, 1973).After reviewing the whole process, it is concluded that the sub-band coding is a method to encode the input signal successfully with maximum efficiency. The two methods used in the process known as MATLAB and C6711 endorse the theory presented in the preceding sections which are considered as valid and reliable.

Attractiveness Of The Hotel In The Industry Tourism Essay

Attractiveness Of The Hotel In The Industry Tourism Essay The process of conducting research on the business environment within which the organization operates and on the organization itself, in order to formulate and implementation of strategy for future business operations can be mentioned as Strategic analysis of hospitality organization. To do the assessment can use number of tools to process of strategic analysis, including PEST (sometimes PESTLE) for analyze external environment and, SWOT analysis use for the internal environmental scanning, and Michael Porter’s five forces model use to assists to understand the competitive forces, the attractiveness and current position in the industry. An effective way to know the past, present and future potentials regarding the industry development is analyzing the industry background as the part of strategic analysis. The External analysis can assess the factors affecting the industry to be existed including political, economical, social, technological, legal and environmental which have great impacts to run the business and use PESTLE analysis. In any industry which it is domestic or international, whether relating to products or services, the rules of competition are personified in five competitive forces of entry of new competitors, threat of substitutes, bargaining power of buyers, bargaining power of suppliers, and rivalry among the existing competitors. According to Porter, one of the crucial determinants of firm profitability is industrial attractiveness. In this assignment, a strategic analysis of the Galadhari hotel which is in hospitality industry has been done through the combination of both theoretical and practical facts regarding this property including organizational background and industry background of this hospitality sector in Sri Lanka, an assessment of the forces affecting the external environment (the use of PESTLE analysis) and an assessment of the attractiveness of this industry (the use of Porter’s 5 forces) regarding the future strat egic action to grab more hospitality market share. Background of the industry and about Organization By concerning about the Sri Lankan market of tourism there can be seen growth in the tourist market. All this euphoria gives rise to the doubt about whether Sri Lanka Tourism is well on the way to recovery and growth or not. For the last seven months that ended July this year (2010), arrivals are up almost 50% year-on-year (YOY) (341,991), with income also keeping pace at 69% growth (Quarter 2; US$ 244.5 million). The hotel and travel Colombo Stock Exchange (CSE) index has been increased by almost 200% for 2009. Today tourism is running on everyone’s minds, and it is difficult to open a local newspaper without seeing at least one written article on tourism. The reason for the dramatic improvement in Sri Lanka’s tourism data is the victory of war in May 2009. This would be a remarkable result when compared with other regional tourism destinations. Another reason for this improvement was the leader of the terrorist has killed and there is reason for cautious optimism that the social situation in Sri Lanka can improve rapidly. We can hope the company can take advantage of the ‘peace dividend’ by increasing the number of destinations the airline serves. Hotel Galadhari is one of the leading five star luxury hotels in the Sri Lanka. The story of the Galadari Hotel, Colombo which opened its doors in 1984, is a splendid tale of continual improvement of product and highest standard of quality in hospitality over the past 25 years.

Cather, Death Comes for the Archbishop Essay Example | Topics and Well Written Essays - 500 words

Cather, Death Comes for the Archbishop - Essay Example Latour in an attempt to revive the integrity of churches strives hard whereas the priest is corrupting the lands of Mexico with his greed for materialism. Religious revival has been pointed out by Cather in the story which co-relates to the current environment of the society. Cather tells as to how religion can bring out a change in the whole society if people have the right belief in it. Such a belief is lost from religions nowadays and it can be seen that greed is prevailing like that of the priest. The importance of religion in the book is conveyed to Latour by Valiant in these words ‘To me, that is the situation in a parable. The Faith, in the wild frontier, is like a buried treasure; they guard it, but they do not know how to use it to their souls salvation. A word, a prayer, a service, is all that is needed to set free those souls in bondage’. This clearly shows that religion can lead to salvation and if an individual is not practicing salvation then this may lead to destruction. Such a condition is prevailing in this world when we see that religious traditions are being ignored all over. Cather gives an account of Latour as to how his revival is successful in bringing glory to the lands of Mexico. A response to religion as shown by Cather has to be followed in this world to bring glory back. Belief is a very important aspect as laid down in the book. The condition of Mexico at one time seemed irreparable but as time passed by Latour grabbed the necessities through which he could bring back salvation to the society. It was through his struggle that this salvation was brought back in the society. Such strength and determination is required by the religious entities in this world today through which they can bring back the glory to this world. Greed is shown to be a destructive factor by Cather and it can only be overcome if struggle religious traditions are followed. Religion has been greatly emphasized in the story and this gives a platform to

International Business - Case Study Example These suggestions and recommendations are further used to chalk out the effective strategies for the accomplishment of organizational goals. Any effective formulation stage always facilitates the ideas and recommendations which are flexible and can be customized as per the emerging challenges and scenarios (Thomas 28). Besides all viable recommendations proposed at this stage need to be pragmatic, realistic and readily implementable. 3. Implementation- In a way this happens to be the most crucial stage of strategy formulation as the eventual litmus test on any effective diagnosis and formulation is that it eventually gets implemented in a methodical and planned manner (Proctor 164). Response- Exchange rates need to be stable and predictable, as reliable and predictable exchange rates have many advantages (Schaefer 46). Stable exchange rates instill confidence in both the importers and exporters regarding the certainty with regards to the foreign payments. Besides unstable exchange rates can wreck havoc on the economies that are predominantly dependent on trade. Unstable exchange can jeopardize the economic growth in such nations. Moreover, stable and predictable exchange rates encourage the international investors to engage in long term investments. In contrast, unstable exchange rates give way to speculative trading in the international capital markets and are more prone to stimulating capital flights from one nation to other. It is a fact that many developing nations do rely on imports to sustain their technology and capital associated requirements. Stable exchange rates enable the developing nations to go on with their development initiatives in a planned an d predictable manner. Stable exchange rates also boost multilateral trade and close trade cooperation between the regional partners. Stable exchange rates are also of pivotal relevance

Schoolbased HIV Prevention Programs Article Example | Topics and Well Written Essays - 1000 words

Schoolbased HIV Prevention Programs - Article Example The objectives of the curriculum are that students will be able to set a personal sexual limit, describe their reasons for maintaining their sexual limit, identify problems that may arise in maintaining their sexual limit and describe how they will address those problems and maintain their limit. The classroom curriculum was developed over a two year period. The researchers used theories about what students needed to postpone sexual activity, we developed activities and then tested them in the classroom. Student reactions to the lessons were observed and they were asked for comments at the end of each lesson. The Healthy Oakland Teens Project (HOT) established by the Center for AIDS Prevention Studies began providing innovative HIV prevention education in Oakland, CA in 1989. The project's goal was to reduce adolescents' risk for HIV infection by using peer role models to advocate for responsible decision making, healthy values and norms, and improved communication skills. The HOT program educated ninth grade students during a one semester, daily class to become HIV peer helpers for seventh grade students. After extensive training, the ninth grade peer helpers delivered weekly interactive sessions in seventh grade science classes, focusing on values, decision-making, communication, and prevention skills. The program trained 30 ninth grade peer helpers who in turn taught 300 seventh graders each year.A parent education program was also implemented for AIDS prevention. Saving Sex for Later is an audio CD program that educates parents about helping their sons and daughters navigate normal p ubertal changes and the challenges of becoming a teenager and supporting them in staying abstinent during the critical early adolescent years. Developed with extensive input from parents and youth, Saving Sex for Later used engaging and dramatic stories to model how parents can communicate effectively with their children. The results showed that listening to the Saving Sex for Later CDs helped parents talk to their children about puberty, romantic relationships, and delaying sexual activity. Youth whose parents received the CDs reported more family rules, greater family support, and less risky behavior.Some interventions to reduce the risk of the acquired immunodeficiency syndrome (AIDS) that target youths have resulted in short-term increases in self-reported condom use. BF Stanton et. al (1997) carried out a randomized, controlled trial of a community-based intervention delivered in eight weekly sessions which involved 76 naturally formed peer groups consisting of 383 (206 interve ntion and 177 control) African-American youths 9 to 15 years of age. A theory-based, culturally and developmentally tailored instrument that assessed perceptions, intentions, and self-reported sexual behaviors was administered to all subjects at baseline and 6 and 12 months later. At baseline, 36% of youths were sexually experienced, and by 12 months of follow-up, 49% were sexually experienced. Self-reported condom use rates were significantly higher among intervention than control youths (85% vs 61%; P
