Optimizing Cash Management Model With Computer Intelligence
Optimizing Cash Management Model With Computer Intelligence Allià and M.M. Ramya Abstract In todayââ¬â¢s technical era, the financial organizations have great challenges to optimize the cash management process. Maintaining minimum cash leads to customer frustration. At the same time, upholding excess cash is a loss to the organization. Hence, soft computing based cash management solutions are required to maintain optimal cash balance. An Artificial Neural Network (ANN) is one such technique which plays a vital role in the fields of cognitive science and engineering. In this paper, a novel ANN-based cash Forecasting Model (ANNCFM) has been proposed to identify the cash requirement on daily, weekly and monthly basis. The six cash requirement parameters: Reference Year (RY), Month of the Year (MOY), Working Day of the Month (WDOM), Working Day of the Week (WDOW), Salary Day Effect (SDE) and Holiday Effect (HDE) were fed as input to ANNCFM. Trials were carried out for the selection of ANNCFM network parameters. It was found that number of hidden neurons, learning rate and the momentum when set to 10, 0.3 and 0.95 respectively yielded better results. Mean absolute percentage error (MAPE), and mean squared error (MSE) were used to evaluate the performance of the proposed model. MSE that was less than 0.01 proves the capability of the proposed ANNCFM in estimating the cash requirement. Keywords: ANN, ANNCFM , neuron, back-propagation, momentum, learning rate. Introduction: Forecasting cash demand needs to be more accurate for any financial organization including banks [1-3]. If the forecast is flawed, in addition to making financial losses to the banks, it results in customer dissatisfaction. In banking industry, an earlier cash requirement study was made using feed forward neural network with back propagation for short term data of two months [1]. Subsequently another comparative study was made for the cash anticipation using a classic time series models and artificial neural networks [2]. The daily cash requirement models for a bank were optimized with particle swarm and compared with least square method for short term data [3]. The main objective of the paper is to design, develop and test a unique supervised method to forecast the cash requirement for banks from their historic data. 1.1 ANN Background ANN is an efficient tool in understanding the complexities of real world problems in all fields of our daily life[4]. It is used as a function optimizer for linear as well as nonlinear problems in science,engineering,technology,management and finance[5-9]. Artificial neural network learning methods provides the best approach for approximating discrete,real and vector valued target functions [10-12], for complex problems, which are not possible to solve by conventional mathematical methods like analytical and numerical technique. ANN are applied in forex market prediction,portfolio optimization,decision making, metrological parameters forecasting[13-19] etc., The various ANN based approaches applied by researchers in finance field as an alternative to traditional time series model includes Financial and economic forecasting, credit authorization screening, simulation of market behavior, mortgage risk assessment, risk rating of investments and detection of regularities in security price movements [15-19]. 2.0 Design of Proposed ANNCFM Architecture: The process of designing a neural network in many fields resulted in a satisfactory performance but building a neural network forecast for a particular problem is nontrivial task. The modeling issues that affect the performance of the neural network must be selected carefully. 2.1. Selection of ANN Parameters In general, the design of multilayer ANN can have many layers where a layer represents a set of distributed parallel processing nodes. The three layered ANN network with one input, one output and one intermediate hidden layer is sufficient to approximate any complex non-linear function. In the case of forecasting studies many experimental results also confirms ANN with one hidden layer is enough to predict the required data [6-8]. The model architecture of ANNCFM is shown in the Fig1. Fig1: Architecture of ANNCFM Model The important critical decision is to determine the architecture is i) number of layers, ii) number of neurons in each layer, iii) number of arcs which interconnect with nodes , iv) activation function of hidden and output nodes, v) training algorithm, vi)data transformation or normalization, vii)training and test sets and viii)performance measures. 3.0 Design of Proposed ANN Models The proposed ANNCFM model consists of one input, one hidden and an output layer as discussed in section 2.1. In this study the data was collected from a semiââ¬âurban area bank located in India. The typical daily cash requirement for thebank for one year is shown in Fig2. Fig. 2: Typical Cash Requirement for a Year The collected data was for a period of three years (2010 to 2012) and was used for training and testing with the following input parameters: RY- Reference year: ranges between 1 to 3 as three years MOY-Month of the year: ranges from 1to 12, WDOM-Working day of the month: ranging from 1 to 27, WDOW ââ¬âWorking day of the week: ranging from 1 to 6, SDE- Salary day effect: ranging from 1 to 3, and HDE- Holiday and the week end effect: either 0 or 1. The fore mentioned parameters were used as six input neurons. In the hidden layer, the number of neurons were varied from 8 to 50.The output layer had one neuron that corresponds to the optimal cash requirement for a day. 3.1 Pseudocode- ANNCFM Main() { [W, V, Voj, Wok]=ANNCFMtrain( x,nip,nh,op,à ±,à ¼,t) yk = ANNCFMtest(ts, W,V, Voj,Wok,t) [Mserr,Mape]=ANNCFMevaluate() } FunctionANNCFMtrain(x,nip,nh,op,à ±,à ¼,t) returns network with modified weight { Repeat { For each training sample x(I,nip) //Feed forward computation //Determine the output neuron between input layer and hidden layer //Determine the output neuron between hidden layer and output layer //Compute the error signal between the output and hidden layer //Update the weights between the output(k) and Hidden(j) layer; If itr=1 then { else End if } //Update bias between the output and hidden If itr =1 then { Else End if } //Update the weights between the input(i) and Hidden(j) layer; If itr=1 then { Else End if } //Update bias between the hidden and input If itr =1 then { Else End if } } Until mse } Function ANNCFMtest(ts, W,V, Voj,Wok,t ) returns output(y) { For each testsample ts //Feed forward computation //Determine the output neuron between input layer and hidden layer //Determine the output neuron between hidden layer and output layer } ANNCFM evaluate(tk ,yk,ts) { } 4.0 Evaluation Metrics: In order to derive and evaluate the performance of the most appropriate model that fulfils our objective of optimizing the cash management, few metrics were used. The accuracy of the proposed ANNCFM is evaluated using MAPE and MSE which are defined as follows: MSE= Where Xt is the actual data at period t, Ft is the forecast at period, t, et is the forecast error at period t, while n is the number of observations. 5.0 Results and discussion: The data for a period of three years (2010-2012) was collected from City Union Bank (CUB)-ukt bank branch to simulate the network using MATLAB .For the proposed study the total number of data for the three years is 879, in which the first two and half years, 737 data were used for training(80%) and the remaining six months 142 data sets (20%) were used for testing. Studies found that input data normalization with certain criteria, prior to training process, is crucial to obtain good results, as well as to fasten significantly the calculations [J.Sola J. Sevilla]. Hence the input data was normalized before training. In ANNCFM, 15 runs were made by varying the number of hidden neurons from 10 to 50 using gradient descent with momentum back-propagation (traingdm) for the default training parameters learning rate =0.01, momentum=0.95, Goal=0, and number of iterations as 6000, are illustrated in table 1-column2. The convergence of ANNCFM is influenced by number of hidden neurons in which by varying the number of hidden neurons between 10 through 50. The error was minimal when the number of hidden neurons was set to 10, 20, 40, 45 and 50, by achieving a MSE of 0.0079 as observed from column 3 of table 1. As the number of hidden neurons increase, there is a significant increase in the computational time. Hence the number of hidden neurons in the proposed study was fixed as 10. The pictorial representation for the optimal hidden neuron against its MSE are shown in Fig. 3. Fig.3: Optimal Number of hidden neurons. The learning rate ââ¬Ëlrââ¬â¢ arrives at a local optimum for the higher learning rate and global optimum for slow learning process. Different trials were made to identify the optimal learning rate to avoid the unstable condition and fluctuations in the results. Learning rate was varied between 0.1 through 0.5 in which 0.3 yielded an optimal learning rate for the given data set, as shown in Fig-4. Fig 4: Optimal learning rate The momentum plays a vital role in identifying the convergence point. Momentum, when set too low, it may get stuck into local minima, and if it is too high, network will become unstable. So there is a need to identify the optimal momentum value for ANNCFM, various momentum values were tested between 0.8 and 1.0, the trained results shows that the optimal momentum value was 0.95 are shown in the Fig-5 Fig 5: Optimal Momentum rate In the ANNCFM model to train and test the cash requirement for a day, week, month the following parameters values are selected based on their performance from the different number of runs made above: i) the number of input neurons=6, ii) maximum number of iteration=6000, iii) learning rate= 0.3, iv) momentum=0.95, v) transfer function=tansig/tansig (hidden and output layer). The optimal selection of the above parameters helped in improving the performance, by minimizing the error rate. This is evident from Table 1, that shows the MSE achieved before and after parameter selection. Table1: ANNCFM performance for different number of hidden neurons The ANNCFM was used to estimate daily, weekly and monthly cash requirement. The estimated values were compared with the actual values for the testing period are shown in Fig.6a,b,c.for the daily ,weekly and monthly prediction. The obtained results shows the ANNCFM was found to perform reasonably good for all the three models .The weights calculated by our ANNCFM was found to be sufficient for cash prediction in which RY,MOY,WDOM, WDOW are essential parameters, and SDE,HDE are additional parameters .The connection weight approach was used to quantify the importance of input variable [20]. The preference of the input parameters were found based on the weights obtained was evident from Table 2, column-4. Table 2: ANNCFM Weights-Preferences. The input parameters SDE and HDE plays a vital role in daily and weekly model as it was observed from the above table it effectively takes care the need of peak cash requirement at the beginning of every month and during holiday periods. The role of SDE in the weekly cash prediction could be easily understood for the weeks like 1,5,14, where the cash requirement is maximum since the beginning of the month lies within the week. However for the 9th and 10th as well as for the 18th and 19th week cash requirement shows the new month starts between the weeks. The monthly model was plotted for six months as shown in Fig.6c in which the experimental results shows that the estimated values were most influenced by WDOM .The cash required and predicted was minimum for the fourth month in which WDOM was minimum. The MAPE and MSE for ANNCFM are shown in Table 3 . Fig.6-a: ANNCFM ââ¬âDaily Model Fig.6-b: ANNCFM ââ¬âWeekly Model Fig .6-c : ANNCFM ââ¬âMonthly Model Table 3 : MAPE and MSE errors for ANNCFM The comparison made between the actual and forecast data shown from the figures indicates that the six input variables selected in our model is sufficient to identify the cash need which is changing from time to time. 6.0 Conclusion: The observations from the experimental results of this study shows that ANNCFM is a useful tool to predict the cash requirement in emerging banking sector. ANNCFM using feed forward neural network training with back-propagation algorithm optimize the needs of cash on daily, weekly and monthly basis. In the implementation process the data set used for the years between 2010 and 2012 were trained and tested to measure the performance. The input parameters were initialized and different runs were made for the proposed model to find out the optimal number of hidden neurons as 10, momentum as 0.95 and learning rate as 0.3 to train and test the network using sigmoid transfer function. The estimated results were with minimal error for the better performance with an accuracy of 91.23%. References.

Mathematics of Light Essay -- Math
Introduction Up to the seventeenth century, most theories attributed color to some sort of modification of light that was thought to occur when light interacted with matter. Light, in its purest form (such as sunlight) was thought to be colorless. However, progress in understanding color was made by Isaac Newton when in 1666 he was able to show that normal white light already contained all the colors of the spectrum, which could be separated using a prism. He also concluded from his experiments that objects have color because they selectively reflect certain colors of the spectrum while absorbing light of other colors. Light is the small part of the electromagnetic spectrum that can affect the human sense of sight. The visible part of the spectrum (for us) ranges from 400 nm (blue) to 700 nm (red). Each wavelength value within the visible band corresponds to a distinct colour. Parameters of light that are of interest to us: Wavelength - the length of one light-wave cycle Frequency - the number of wavelengths per second Three attributes are used to specify a color: hue, saturation and brightness. These describe only the perception of light, not its physical properties. 1. Hue - a feature of monochromatic light that varies with wavelength and used to denote the various regions of the spectrum (in other words, the basic color from the spectrum). 2. Saturation - how much a color differs from white (ie vivid pure color versus pastel color) 3. Brightness - the perceived intensity of light Spectral Power Distribution Monochromatic light is light that has only one wavelength, and thus cannot be further divided into different components using a prism. But most light sources are not monochromatic ... ...d (B) of wavelength 435.8nm. This means that given an RGB color (C) = L1(R) + L2(G) + L3 (B), its coordinates in the XYZ system are: X = 2.7689*L1 + 0.38159*L2 + 18.801*L3 Y = L1 + L2 + L3 Z = 0 + 0.012307*L2 + 93.066*L3 This particular transformation was chosen so that the XYZ system would have several convenient properties. One is that there are no negative tristimulus values, which reduces the possibility of error. Another is that the color triangle enclose the spectrum locus as closely as possible.

Great expectations coursework Essay
My essay is going to be about the 1876 edition novel ââ¬ËGreat Expectations. ââ¬Ë The author of this novel is Charles Dickens. When the novel opens we meet Pip as a rather young child. Pip is the narrator as well as the main character. This is known as the first person. Pip as an adult talks about Pip as a child. He talks about his life as a child and how it was a struggle without his parents being around to help him. This makes it interesting to read. Dickens creates sympathy for Pip by talking about his dead parents. ââ¬Å"As I never saw my father or my mother, and never saw any image of either of them. â⬠This suggests that Pip never saw his parents because he was young when they died. Pip also tries to create an image of what they looked like. Another way Dickens creates sympathy is by talking about Pipââ¬â¢s dead brothers. ââ¬Å"They all had been born on their backs with there hands in their trouser pockets. â⬠This makes us think of them in a childish way like the young Pip. In the 19th century people used to die commonly so if they read this novel they wouldnââ¬â¢t suffer any sympathy because the death rate was regular. If a person read this novel in the 20 century they would feel sympathy because the death rate is much less and we are not used to children dying anymore. Dickens knew what a poor existence was like as a child because he had been through it all. He came from a working class family. In his school the teacher paid particular consideration to Dickens because he was making incredible progress but he was forced to leave school at the age of 12 and go labour in a factory because his parents were in enormous debt. To write this book Dickens got his sympathy from his early days. What he saw in his time made him want to write about how life wasnââ¬â¢t fair. The opening chapters are good at getting us to feel all sorts of emotions. The way Dickens gets the readers awareness is he creates a tense, terrifying setting. The reader then knows something dreadful is going to take place so he reads on. Dickens describes how frightening the setting is. ââ¬Å"The small bundle of shivers growing afraid of it all and beginning to cry was Pip. â⬠This suggests that he is extremely terrified of the graveyard that he is in. Dickens describes the graveyard as a hiding place for people. ââ¬Å"And that the distant savage lair from which the wind was rushing was the sea. â⬠This suggests that the grave yard can be used as a hiding place because of its darkness and emptiness. All of this makes the reader really scared so that we can feel the same as Pip. Dickens was especially renowned for the good way he created his characters. We meet one of his bloodcurdling characters in this novel. Dickens describes the character as a fearful man, all in course grey, with a great iron on his leg. A man who had been ââ¬Å"soaked in water and smothered in mud, and lamed by stones, and cut by flints and stung by nettles, and torn by briars; who limped, and shivered. â⬠This suggests that the man had been through an awful lot to get to where is. He also wanted to really escape from the prison that he was held in. We know that he had been to prison because of the great iron on his leg. We also know that he had been beaten by stones, drenched in water, smothered in mud, slashed by flints and unpleasantly cold. I can feel what he is feeling because of the words Dickens uses. Dickens uses dialogue to state where his characters come from and how their personality is. The convict uses dialect language. ââ¬Å"Show us where you live, pint out the place. â⬠This tells us that the convict doesnââ¬â¢t use correct English language instead of saying ââ¬Ëpointââ¬â¢ he says ââ¬Ëpintââ¬â¢ missing out the ââ¬Ëoââ¬â¢. this tells me that he is from a working class not a middle class like Estella or other ladies and gentlemen. Dickens is very intelligent the way he creates his characters names. This helps use to discover what the characters are like and what part they play. Mrs Joe Gargery takes on her husbands name to show other people that sheââ¬â¢s the one who obeys her husband. The reader sees a different side. Mrs Joe Gargery is the one in charge and her husband obeys her. Dickens is using ironic humour here to make us laugh at the situation. I liked the first two chapters of the novel that I studied because it was very thrilling to examine about how existence was like in the historic days. I liked the way Dickens wrote this novel because he described the background in a lot of detail.

Why I am Pursuing a MBA Degree Essay - 1032 Words
Why am I Pursuing an MBA degree? I decided to pursue an MBA degree in order to further my managerial career in the company I work for. The question would be: Why do I think it will enhance my management career? The answer to that question requires short background information. I started my career as an entry level programmer in 2000, after receiving my bachelorââ¬â¢s degree in computer science. My career took a turn to management in 2003 when I was offered a team leadââ¬â¢s position with the company I was working for. Since, I worked myself up through the ranks to my current position of a Manager, responsible for a sub-unit handling a specific application product.

The 2007 issue of the Application Trends Survey Report, published by the GMAC (Graduate Management Admission Council), reports that application volume has risen about two-thirds for full-time, two-year, part-time, and executive programs (GMAC, 2007). Moreover, according to the PayScale Salary Calculator the median salary range for managers in IT Telecom field in Texas is without MBA is $68,387 - $81,917, but the median salary range for managers in the same field and in the same state with MBA is $82,897 - $104,964, an increase of 30%- 45% (PayScale). The MBA has proven to be a lucrative degree. The International Recruitment Survey and Salary Report 2007, conducted by QS TopMBA.com, reveals that MBA salaries across most major industry sectors have increased more rapidly than salaries for non-MBAs. The report confirms that the MBA is the highest paid postgraduate qualification. (Quacquarelli, 2008) Increased earnings potential and market demand aside, how well am I suited for an MBA degree? According to the Jungian Personality self-assessment, I am an ENFJ. According to Scott Graverson, in his dissertation, the ENFJ personality is an Idealist-Teacher (2008, p. 55).

Phoneme vs Minimum Pair in English Phonetics
In phonology andà phonetics, the term minimal pair refers to two words that differ in only one sound,à such as hit and hid. Minimal pairs serve as tools to establish that two (or more) sounds are contrastive. A difference in sound means a difference in meaning, notesà Harriet Joseph Ottenheimer, and thus a minimal pair is the clearest and easiest way to identify phonemes in a language (The Anthropology of Language, 2013). Examples and Observations A minimal pair is a pair of words that differ in a single phoneme. Minimal pairs are often used to show that two sounds contrast in a language. For example, we can demonstrate that [s] and [z] contrast in English by adducing minimal pairs such as sip and zip, or bus and buzz. Since the only difference in these words is the [s] vs. [z], we conclude that they belong to distinct phonemes. However, a similar test would show that [a:j] and [Aj] are distinct phonemes in English, since writer and rider appear to be minimal pairs distinguished in their second elements, not their fourth.We looked!Then we saw him step in onthe mat!We looked!And we saw him!The Cat in the Hat!Cheers and Jeers is an activity that provides an opportunity to use music and humor to relax and release tension.Lit Up/Let DownThe learner has to identify medial or final plosives in isolated words and in sentences where either member of a minimal pair would fit in naturally. For example: Do you repair clocks/clogs?Unless someone like you cares a whole awful lot, nothing is going to get better. Its not.The US Coast Guard had 125-foot cutters and eight 765-foot long patrol boats.

Word Position and Context [T]he only way we can create a minimal pair with reference to the two sounds involved is to put them in exactly the same environment in terms of word position and the surrounding context, To clarify further,à the pair: jailââ¬âYale shows the contrast betweenà /dÃâ/ and /j/ in initial position, budgeââ¬âbuzz focuses on the contrast between /dÃâ/ and /z/ in final position, while witchââ¬âwish contrastsà /tÃ¢Ë «/ and /ÃÆ'/ in final position. It should be noted that minimal pairs include forms that have different spellings, as evidenced inà jailââ¬âYale. Near Minimal Pairs [S]ometimes it is not possible to find perfect minimal pairs differentiated by only a single sound for every phoneme. Sometimes it is necessary to settle for near minimal pairs ...à [P]leasure and leather qualify as a near minimal pair, since the sounds immediately adjacent to the target sounds, [à °] and [Ãâ], are the same in both words: [Ãâº] before the target sound and [à ¹] after it. Like minimal pairs, nearà minimal pairs are usually sufficient to demonstrate that two sounds are separate phonemes in a language.

Essay on How Oil Prices are Established - 1367 Words
How Oil Prices are Established Did you realize that at our current consumption of crude oil and at our current status of known reserves, we have approximately 40 years of reserves remaining? This is a startling fact when we take into account all the products that are produced from refined crude oil or from its by-products. Many people are aware of the price increases they feel at the gas pump, but has anyone ever considered the cost or investment put forth in finding new reserves? Under the right conditions, oil would sometimes seep up to the surface, but in our times, the search for new reserves is more costly and dangerous. When considering how the price of crude oil and its by-products are determined, one must first look at theâ⬠¦show more contentâ⬠¦Through various news sources, there has been reported an increase in weather occurrences that cause temporary shortages in crude oil production. The largest of these occurrences has been from hurricanes. When a hurricane is reported and the path is determined to cross through offshore oil platforms, all production must be stopped and crews evacuated for their safety. Only once danger has passed, will production resume. This sometimes can be just a few days or longer, depending on if any damage has occurred. In 2005, the Gulf of Mexico experienced two hurricanes that devastated offshore and onshore oil production facilities. Offshore oil platforms were broken from their moorings and driven to shore, and onshore refineries suffered tremendous damage from flooding and high winds. Another weather occurrence that can have a dramatic influence on pricing is the onset of winter. Rather than winter weather causing supply shortages, the demand increases from consumers requiring fuels for heating. However, weather is not the only factor that influences pricing. With most of the known reserves currently producing and slowly depleting, the search for newer sources takes the producers into areas originally thought too harsh or uneconomic to tap. When the oil and gas industry was in its infancy, crude oil could be found in pools on the ground surface. This was caused by cracks in the geological formation. As crude oil isShow MoreRelatedEssay about Monopoly of Petroleum: OPEC1037 Words à |à 5 PagesThis essay will discuss the monopoly of petroleum by The Organization Of Petroleum Exporting Countries (OPEC), particularly how it controls the price of petrol, threats to its monopoly and the social costs involved.

Something Strange Happens Every Day Essay Example For Students
Something Strange Happens Every Day Essay A man, Bob Johnson, leans on a cold, concrete pillar, silently waiting for the train to take him to work. He waits as he has waited for the past seven years of his monotonous, somewhat mechanical existence. He glances calmly at his wristwatch; thirty-seven minutes past eight o clock in the morning. Damn, he thinks to himself. Oh well, theyll have to let me off, he mumbles to himself, its the first time Ive been late in the seven years Ive worked there. So, Bob slowly makes his way to the edge of the platform so as to get a good seat on the train. Around him, people mill around waiting for the same train Bob waits for. Directly behind him, a fat woman sits on a wooden bench holding her designer label bag in her lap, close to her chest. She is obviously very self-conscious and she glances around nervously. Nearby the fat lady, three African-American guys, aged around 20, dressed in ridiculously oversized clothing, listen to a rap song on a portable stereo. To his left, a businessman and his associate stand underneath a train schedule board discussing some important topic. Near him stands a group of Japanese tourists, looking at a half-folded map, trying to figure out the best route to arrive at their destination. Two of them are in a heated argument, speaking very quickly in Japanese. Bob then catches a glimpse of a crowd of school kids heading towards the platform with their chaperones; they are going on a day-trip to the Natural History Museum. While Bob is lost in his silent study of the Human-Being, the advance warning lights lined along the edge of the platform where there is a six foot drop to the train tracks, warning people that the train will arrive in just a few moments. Everybody hears the high-pitched squeal of metal wheels on metal rails, and a sudden rush of air against his face from the fast moving train brings Bob back to his senses. At this moment everyone waiting for the train; the fat lady, the homeboys, the business associates, the tourists and the school group, in amongst a slew of other interesting people; begin crowding the platform where Bob calmly waits to go to work. In all the rushing, panic, and pushing of people, Bob Johnson, who was waiting calmly to get onto the train, somehow gets jostled by the wave of people and topples over. He falls straight into the middle of the tracks. Chaos. Somebody screams, everybody looks, everybody screams, everybody runs. Bedlam takes over; no one knows quite exactly what to do. Bob, after what seems like an eternity, pushes himself slightly off the ground and spits some blood to the gravel floor. Looking straight at the ground, still gathering his senses, he is abruptly hit with a state of shock and confusion. He hears the growing screeching noise of the trains breaks. He looks up and to his right and sees the trains lights and bulking mass, bearing down on him. At the moment just before impact, and Bobs almost-apparent death, some ones muscular hand grabs him by his arm and pulls him off the path of his surefire demise, leaving only Bobs briefcase to be torn apart by the quick-moving train. Every single last muscle in Bob Johnsons body aches and he cant stop himself from shaking. All he feels is adrenalin pumping through his mind, and his body. He finally gains his senses back, and sits up impulsively, and looks around. A feeling of relief floods through him where the adrenalin once did before. It was only a dream. He is now in the comfort of his own bed, he looks over on his bedside stand, at his alarm clock, it is five o clock in the morning and the sounds of a city gearing up and preparing for a long day fill his head. He gets up and starts his morning routine. He takes a nice refreshing shower, and eats some almost-burnt toast and drinks a glass of orange juice, just as he has showered and eaten breakfast for the past seven years of his monotonous life. As he is getting dressed into his work clothes, he feels a strange aching sensation in his neck, as if he had pulled a neck muscle, or pinched a nerve. At the same time, he has a sore throat and his voice is very ras py. He coughs loudly and thinks nothing of it. All he can think about is the incredibly lifelike dream that he had, so he decides to call his mother just to say hello and to take his mind of the odd dream. He picks up the phone and dials in the ten digit number, he is taken aback by the cold, machine-like voice of a recording, The number you have dialed has been disconnected, please hang up, and try the number again. He instead tries another number. And another one, and another one. Its all the same; theyve all been disconnected. Finally he decides that the phone lines must be down, or his apartment was disconnected for not paying their bills, and he walks out his door. .u10d20a96aeb5f5c54cf1e2b89afb0379 , .u10d20a96aeb5f5c54cf1e2b89afb0379 .postImageUrl , .u10d20a96aeb5f5c54cf1e2b89afb0379 .centered-text-area { min-height: 80px; position: relative; } .u10d20a96aeb5f5c54cf1e2b89afb0379 , .u10d20a96aeb5f5c54cf1e2b89afb0379:hover , .u10d20a96aeb5f5c54cf1e2b89afb0379:visited , .u10d20a96aeb5f5c54cf1e2b89afb0379:active { border:0!important; } .u10d20a96aeb5f5c54cf1e2b89afb0379 .clearfix:after { content: ""; display: table; clear: both; } .u10d20a96aeb5f5c54cf1e2b89afb0379 { 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; } .u10d20a96aeb5f5c54cf1e2b89afb0379:active , .u10d20a96aeb5f5c54cf1e2b89afb0379:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u10d20a96aeb5f5c54cf1e2b89afb0379 .centered-text-area { width: 100%; position: relative ; } .u10d20a96aeb5f5c54cf1e2b89afb0379 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u10d20a96aeb5f5c54cf1e2b89afb0379 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u10d20a96aeb5f5c54cf1e2b89afb0379 .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; } .u10d20a96aeb5f5c54cf1e2b89afb0379:hover .ctaButton { background-color: #34495E!important; } .u10d20a96aeb5f5c54cf1e2b89afb0379 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u10d20a96aeb5f5c54cf1e2b89afb0379 .u10d20a96aeb5f5c54cf1e2b89afb0379-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u10d20a96aeb5f5c54cf1e2b89afb0379:after { content: ""; display: block; clear: both; } READ: The Kung, Shoshone, and Mbuti Tribes: Hunting and EssayThe moment he closes his apartment door behind him, everything goes silent.

Bob walks down the cold, concrete stairs, and everything just gets darker and darker until he finally reaches the floor of the parking garage. At this level, it is pitch black and he cant see anything, but he decides that along with the phone lines, there must be a power failure. He slowly and cautiously makes his way to where he parks his car. Suddenly, Bob finds himself on the ground with his briefcase by his sid e. He looks behind him and convinces himself he tripped on something in the dark. He slowly pushes himself up off the ground only to be startled by a car coming straight at him with its headlights on full beam, he hears the screeching of breaks, almost like metal on metal. As the car hits him, the headlights completely engulf him and he feels a moment of disconnectedness and a feeling of incorporeal like he is no longer in his body. Bob Johnsons body lay twitching on the subway tracks as the train came to a screeching halt. He had been decapitated. Creative Writing Essays
