Synthesis - Term Paper Example The thinking is that as a practicum, it is important to spend time doing things that have potentially large impact on the community and on the lives of poor people especially, and student achievement among those along the margins of poverty need to be understood in the context of larger family and social dynamics for interventions to have any chance of succeeding (Schoolwires, 2014). Title 1 refers to the program that is funded by the federal program and is of the biggest of its kind in the United States, with the goal of providing financial and related support to schools with large proportions of being at risk of not meeting academic standards due to poverty. In its original form, it achieved the force of law under the Elementary and Secondary School Act of 1965, and this was later revised in 1994 to tweak the overall goals of the program. In its current state under the No Child Left Behind, schools have to meet academic standards progress in achievement as reflected in yearly state testing in order for continued inclusion in the funding program. The annual money earmarked for the program is pegged at $14 billion, and in recent years as many as 56,000 different schools across America have tapped into the program funding (US Department of Education, 2015; Malburg, 2015). It is important to note that the Abilene Independent School District or AISD in general is a school district that naturally meets the standards for government support under the Title 1 program of the legislation on No Child Left Behind and earlier legislation that originated the idea of providing additional funding and support to school districts that have large numbers of students living in poverty or near the poverty line. This is because large numbers of residents in the school district are poor, and make substantially less than the average American worker on a

Development of a Deep Sea ROV

Development of a Deep Sea ROV Jeremy Moros Abstract Australia’s geographical location places it within reach of 65% of the world’s salt water oceans. However, to this day, only 0.9% of the oceans depths have been explored. This journal explores whether or not current technologies allow for the possibility of a series of imagery and sensory underwater drones gathering data from unexplored biological habitats and ecosystems, where the costs and safety of human expeditions have been prohibitive. To discover these depths the proposal for an Unmanned Scientific Data Gathering and Collection System (USDGCS) has been explored to determine whether existing open source platforms such asArduino can be utilised to create a system where once deployed can collect and redistribute first hand data live across the internet. The drone must be designed to perform a large array of tasks, whether it be the photographing and mapping at extreme depths, or the monitoring species populations close to the surface. Ultimately, a model that is fri endly to the environment in which the ROV operates is essential so the self-powering drones have been explored. Keywords Underwater Drone, Ocean, Remotely Operated Vehicles, UAV Introduction ROV’s are commonly referred to as an acronym for â€Å"Remotely operated vehicles†. ROV’s can be classified as one of two types of drones, Underwater ROVs and aerial UAVs (Unmanned Aerial Vehicles). Similar principles allow for the similar technologies in such drones however the medium in which they operate differ. In each classification, drones such as AUVs (Autonomous underwater vehicles) do not require constant control from a human, but instead rely on prewritten algorithms. These algorithms make use of self-navigating equipment such as using sensors and radars to determine their location and perform functions with an accuracy dependent on the equipment on board. The extreme water pressure experienced at depths below a few hundred meters are enough to kill a human. ROV’s were developed to overcome the limitations of deep-sea divers where they have proven to be of much use in the gas and oil industries. The first form of a drone was the 1960’s HOV or Human Operated Vehicle. However basic, it demonstrated the very first development of drone technologies. It was the US Navy that funded and developed more of early ROV technologies through the 1960’s program Cable-Controlled Underwater Recovery Vehicle (CURV). This vehicle was created to be cable of performing sophisticated deep-sea rescue operations, such a  recovering black boxes from previously destroyed military aircraft and retrieving highly dangerous devices such as a nuclear weapons. The â€Å"CURV† removed any danger to the humans that operated them and was considered as a milestone in technology. However, many of the technologies incorporated into were develo ped for scientific research purposes. ROV’s today underwent development when drones were developed for scientific research purposes. These technologies include the addition of live streaming video cameras and lights sources, where it became easier for a ROV to be precisely controlled by an operator. Now in the 21st century, many components are commonly integrated to expand a vehicle’s capabilities. These may include mapping sonars, magnetometers and high resolution digital cameras, as well as more sophisticated tools such as instruments that can accurately determine water temperature, clarity and light penetration. Specialised drones may feature cutting arms or manipulators that can gather rock or flora samples for low depth environments ( Purpose of investigation The purpose of this investigation is to determine whether current technologies allow for the successful development of a deep sea ROV where data can be collected and redistributed live through the World Wide Web without costs being prohibitive. 2 Context: Parts of a ROV The ROV is commonly consists of 4 systems, each of which serve a specific function. 2.1.1 The Frame: The frame of a ROV serves as the primary skeleton of the vehicle. Often constructed beams, struts or plates as the frame bears the load of the water pressure. The frame often defines the overall shape of the ROV as mechanical and electrical components often need to be secured inside the frame for successful operation. This includes weights, pressure canisters, thrusters, floats, camera, lighting and other instruments like manipulator arm, sonar, scientific sensors, etc. ROV frames can be made from a range of materials including plastic composites and aluminum tubing and the choice is based on the developmental requirements of a ROV. Due to the highly saturated salt solution in the ocean, corrosion resistant materials with high strength and low density have been favorably considered. Since weight has to offset with buoyancy, this is critical. A well designed frame aims for easy repair if components are to fail, as well as a shape that will aid easy control. 2.1.2 Buoyancy System: A ROV owes its ability to stay afloat due to its buoyancy system. The principle to the floatation of an ROV is the attainment of neutral buoyancy of the ROV system as a whole. If neutral buoyancy is achieved, a ROV is capable of floating in water and can rise and descend when needed. There are many ways in which buoyancy can be achieved, the most simple being the attaching of floats to a ROV. In more sophisticated ROVs, a dedicated buoyancy system is incorporated into the design. A Ballast system is of two types, an active and static ballast system. An active Ballast system is more sophisticated as it can adapt to changes in weight of a system. A static ballast system is far less sophistical, where floats and other simply floating devise such as air filled cans provide a fixed buoyancy range beyond which the ROV will sink to the ocean floor. However, if the static ballast system has a fixed buoyancy too great, the ROV will never dive, no matter the thrust from a propulsion system. 2.1.3 Propulsion System: Thrust is required for the control of a ROV, which is provided by a propulsion system. The thrust produced should be more than the drag force acting on the system, thus a more aerodynamic design is advised. A range of propulsion systems have been developed, however the most common would be a combination of bilge pumps and underwater rotors to propel the craft. The motor inside a ROV should be adequate to propel the ROV forward, as well as stop it in a short time. High torque motors of 800-2000 RPM rotors are considered to be sufficient for underwater drones. The number of thrusters required is dependent on the functions a ROV will perform. It is known that the greater the number of thrusters, the more freedom in the movement of the ROV. The propeller attached can be a 3 blade or 5 blade depending on the speed and water density through which the ROV will traverse. Brushless DC motors are preferred over other types of motors due to the fact that they offer a hi gher efficiency, hence offering better control of a ROV’s speed. DC motors are often far cheaper than a similarly outputting AC motor. 2.1.4 The Electronic System The electronic system of the ROV encompasses the payload of the ROV. The ROV system should have a water tight enclosure for the electronic and electrical components. A variety of electrical components are used for a number of purpose such as driving power, lighting and video feed, etc. The wiring should be secure and watertight to ensure that the chances of water damage to electronics is kept to a minimal chance. The wiring is often kept far clear of the rotors to reduce any chance of entanglement. The video feed can either be stored on an on-board system or transferred to the control room via a tether or a however recent technological advancements are allowing for a wireless connection to the surface. The ROV often receives electrical commands through the same radio device as the video feed, whether it be wired or wireless. Micro Controllers are considered an ideal option for analogue control as development is not required for a new embedded PC board, hen ce lowering costs. The Arduino platform utilizes these micro controller boards and is an example of a cheap, but effective solution. These controllers allow for sensory data to be collected from various instruments. Some ROVs are designed to incorporate instruments where they are capable of performing a standard set of operations. The power source of a ROV is dependent on the depth it is required to travel. Low depth ROV’s are able to leave a power source on the surface and are powered by an electrical cable. However, a ROV designed to dive deep proves a long electrical cable impractical and therefore warrant onboard batteries with 5-12 Volts. A photovoltaic cell can be installed on the ROV and be used to recharge the battery when resurfacing.

Shakespeares Definition Of A Ghost Essay -- essays research papers

Shakespeare's Definition of a Ghost The American Heritage Dictionary, published in 1973, defines a ghost as, "the spirit or shade of a dead person, supposed to haunt living persons or former habitats." Unfortunately, this simple definition does not explain where a ghost comes from or why it haunts. When used in the context of Shakespeare's Hamlet, this definition seems to suggest that the ghost who visits Hamlet truly is his dead father seeking revenge. To the modern reader, this straightforward interpretation adequately characterizes the ghost and his purpose; however, to the Elizabethan audience the ghost's identity proved more complex. For the Elizabethans, four different types of ghosts existed, each with its own purpose and qualities. Before they could determine the meaning behind the ghost's appearance, the Elizabethans had to classify the ghost in one of the four categories. Similar to the modern definition, the Elizabethans believed in the possibility of the ghost being an actual dead person sent to perform some task or mission. On the other hand, the ghost could be the devil disguised in the form of a deceased loved one, tempting to procure the soul of one of the living. The nonbelievers among the Elizabethans saw ghosts as omens, telling of troubled time ahead, or simply as the hallucinations of a crazed person or group. Shakespeare recognized the complexity of the Elizabethan ghost's identity and played off of the confusion, making the question of identity a key theme to his play. Throughout Hamlet Shakespeare explores each of the possible identities of the ghost with each one adding a new twist to Hamlet's plight. When news of the ghost's presence first reaches Hamlet and Horatio, they declare it an omen of forthcoming evil. Hamlet's reaction indicates that he is not surprised, "My father's spirit - in arms? All is not well. / I doubt some foul play. Would the night were come! / Till then sit still, my soul. Foul deeds will rise, / Though all the earth o'erwhelm them, to men's eyes" (I.iii.255-259). Hamlet already believes that Gertrude has committed a "foul deed" in marrying Claudius and the ghost's appearance supports Hamlet's anger. At the time, Hamlet does not know of his father's murder, but he suspects there may be more behind the ghost's appearance... ... revenge and kill Claudius. Before, the ghost was the only proof Hamlet had of his father's murder and he needed its assurance in order to act out his revenge. After The Mousetrap and Claudius' reaction, Hamlet has seen with his own eyes the King's guilt and has enough evidence to seek revenge on his own - the reality of the ghost is no longer needed. Depending on the view of the ghost, the tragedy of Hamlet can be understood in several distinct ways. When seen as an omen, the blood bath with which the play ends is both unavoidable and foreshadowed. If the ghost is truly Hamlet's father, than Hamlet dies heroically, revenging his father's untimely murder. On the other hand, if the ghost is really the devil, Hamlet has been tragically tricked into relinquishing control of his soul; sadly Hamlet knew better, but his reasoning and intelligence were no match for the devil's guile. Finally, the hallucination view of the ghost presents Hamlet as a tragic character whose obsession with his father's death and his mother's incestuous marriage lead to his downfall. Regardless of the reality or validity of the ghost, Hamlet's death and thus his tragedy, remains.

World Hunger

We will often hear of people’s desire to solve world hunger, or to help feed and alleviate the suffering associated with it. However, meaningful long-term alleviation is rooted in the alleviation of poverty, as poverty has always led to hunger. As our efforts have only been directed at providing food, and improving food production or distribution, we then generate the structural root causes that create hunger, poverty and dependency to still remain. Along with this; continuous effort, recourses and energies are given to relieve the pains of hunger in our world. There are many inter-related issues that are the cause of hunger; these are also the same factors that are known to cause poverty. Agricultural practices, war, drought, overfishing and the wasting of food; are some of the many causes of both world hunger and poverty. Because they are connected in a way; solving world hunger becomes hard and nearly impossible to stop. Both hunger and poverty have always led to each other in the end; making the issue uncontrollable and unstoppable. In order for one of these issues to be solved, would require the alleviation of the other; causing a long, endless chain of continuation. Hunger and poverty are very serious issues, and in no way should just be swept under the rug. The amount of food that gets thrown away each day is shocking; and could probably feed 100 people. We don’t do this intentionally; but we waste pounds of food each day, by taking more than what we truly need. World Hunger is something that shouldn’t be such a big problem; but the truth is-it is, it always has been, probably always will be. We’ve got to stand our ground and fight hunger and poverty, cause they can’t do it alone, no one can. We must begin to think a little less about ourselves, and a little more about each other. World hunger and poverty have become very important to me because I have helped out at a homeless shelter, and I have seen the faces of these people; I’ve had the oppertunity to make a connection with them, a connection that most people wouldn’t understand. These people are fighters, you can see it in their eyes. They are survivors of the biggest battle, a battle that they shouldn’t have to fight, a battle that most people don’t even have to think about; and the amazing thing is, they haven’t stopped; their still fighting. They shouldn’t have to do this alone, I am one out of probably a million people who are trying to help them fight this battle; cause I care. All it took was one day, and it has completly changed my life. Seeing all these people, looking into their eyes, feeling their pain; yet seeing a heart full of hope and joy. It has become a life-changing experience that I will never forget. In conclusion, there are a lot of people in our world, with enough food to provide everyone twice a day, yet there are still so many people that are suffering and dying of hunger. We have to face this problem, not turn away from it. I have personally grown to love these people with all my heart, because what they have gone through is truly amazing. They have changed my life forever, and I hope a can help change theirs.

Related Literature to the Cash Flow Management Essay

The role of cash flow information in discriminating between bankrupt and non-bankrupt companies remains a contentious issue. In a number of literature reviews on bankruptcy prediction (e. g. Zavgren, 1983; Jones, 1987; Neill et al. 1991; Watson, 1996) the common view is that cash flow information does not contain significant incremental information content over accrual information in discriminating between bankrupt and non-bankrupt firms. (Divesh S.  Sharma, Senior Lecturer, School of Accounting, Banking & Finance, Faculty of Commerce & Management, Griffith University, Nathan, Queensland 4111, Australia) A cash flow statement is an important indicator of financial health because it is possible for a company to show profits while not having enough cash to sustain operations. It is a financial report that shows to the user the source of a company’s cash and how it was spent over a specific period of time. A cash flow statement counters the ambiguity regarding a company’s solvency that various accrual accounting measures create. It also categorizes the sources and uses of cash to provide the reader with an understanding of the amount of cash a company generates and uses in its operations, as opposed to the amount of cash provided by sources outside the company, such as borrowed funds or funds from stockholders. The cash flow statement also tells the reader how much money was spent for items that do not appear on the income statement, such as loan repayments, long-term asset purchases, and payment of cash dividends (Ryan 2007).

Beaver (1966) reported that cash flow from operations (CFFO), proxied by net income plus depreciation, depletion and amortisation, to total debt had the lowest misclassification error relative to common accrual measures of financial health. However, his univariate approach to analysing financial distress was seldom followed because while ne ratio would indicate failure another could indicate non-failure. Altman (1968) overcame this problem through the use of multiple discriminant analysis (MDA) that simultaneously considers financial ratio indicators of corporate health. Altman (1968) did not examine the value of cash flow information though. Deakin (1972) demonstrated employing MDA that cash flow to total debt was a significant predictor up to three years prior to failure. Like Beaver (1966), Deakin (1972) defined cash flow as net income plus depreciation, depletion and amortisation. While other researchers (e. . Blum, 1974; Norton and Smith, 1979; Mensah, 1983) have shown that cash flow information contains information content in predicting corporate bankruptcy, they are not frequently cited. The rare citation is probably due to the measure of cash flow employed by these researchers. These researchers used Beaver’s (1966) definition of CFFO. Table 1 summarises the research findings of the cash flow failure prediction literature to date. Largay and Stickney (1980) recognised the limitation of using net income plus depreciation, depletion and amortisation (NIDEP) as a measure of CFFO. They demonstrated based on the infamous W. T. Grant Company bankruptcy that NIDEP more correctly reflected working capital from operations. To determine CFFO one had to adjust for changes in current assets and current liabilities other than cash. Largay and Stickney’s (1980) more refined measure of CFFO indicated that W. T. Grant’s cash from operations was negative in eight of the ten years prior to failure while NIDEP was relatively steady until the year immediately prior to its demise. This finding renewed interest in CFFO as an indicator of corporate failure. Lee (1982), a strong advocate of cash flow reporting, showed that the fall of Laker Airways was foreseeable on a cash flow basis. His analysis of CFFO revealed that Laker Airways was in financial trouble three years prior to failure while profits were increasing as failure approached. A stream of multivariate modelling studies began investigating the information content of this refined measure of CFFO. Using an estimation sample and a validation sample comprising 60 bankrupt and 230 non-bankrupt firms and three measures of cash flow information, viz. CFFO, CFFO/Current Liabilities and CFFO/Total Liabilities, Casey and Bartczak (1984; 1985) concluded that none of the three operating cash flow variables significantly improved the classification accuracy of the six accrual ratios model. Casey and Bartczak (1985) reached this conclusion on the basis of the number of firms correctly classified into their respective groups. While their conclusion is valid, there are grounds to argue that cash flow information has significant information content over accrual information in assessing the predicted probability of failure. Predicting the probability of failure extends the mere classification into either the failed or nonfailed group and is practically more useful. For instance, the classification of a company into a non-failed group does not provide information on the likelihood of this group membership. Consistency Principle Consistency Principle is one of the four major principles that are used for estimating the project cash flows. According to this principle, consistency in the cash flows is very necessary. At the same time, consistency in the applicable discount rates on the cash flows should also be maintained. There are two important factors that are related to the Consistency Principle. These two are the investor group and the inflation. Investor Group: The Consistency Principle holds that while estimating the project cash flow, it is also important to consider the investor’s opinion or view. There are different types of investors in a firm like the lenders or the stockholders and so on. Again, if it is not possible to consider every kind of investors’ view, then the stockholder’s view regarding the cash flow may be considered. According to the investor’s standpoint, the project cash flow denotes that amount of cash that is provided to the investors. The payable taxes must be deducted from this amount and if there is any need for investment in the ongoing project then that amount should also be deducted from the amount allotted for the investors. At the same time, if the stockholders standpoint is regarded then the project cash flow is that amount that is offered to the stockholders. This amount should not include any kind of payable tax or any such amount that is necessary to invest in the particular project. Again, before offering any money to the stockholders, the firm is required to clear all the debts. Now, the next important factor is the consistency of the discount rate that is to be applied on the project cash flow. There are two types of discount rate known as the weighted average cost of capital and cost of equity. Inflation: In case of inflation, there are two ways of estimating the project cash flow of a particular project. The first option is to merge a likely inflation in the project cash flow estimates. After this, a nominal discount rate is applied on the amount. Another way of handling the inflation factor is to calculate the project cash flows of the future in real terms with real discount rates. Cash flow estimation is a must for assessing the investment decisions of any kind. To evaluate these investment decisions there are some principles of cash flow estimation. In any kind of project, planning the outputs properly is an important task. At the same time, the profits from the project should also be very clear to arrange finances in a proper way. These forecastings are some of the most difficult steps involved in the capital budgeting. These are very important in the major projects because any kind of fault in the calculations would result in huge problems. The project cash flows consider almost every kind of inflows of cash. The capital budgeting is done through the co-ordination of a wide range of professionals who are going to be involved in the project. The engineering departments are responsible for the forecasting of the capital outlays. On the other hand, there are the people from the production team who are responsible for calculating the operational cost. The marketing team is also involved in the process and they are responsible for forecasting the revenue. Next comes the financial manager who is responsible to collect all the data from the related departments. On the other hand, the finance manager has the responsibility of using the set of norms for better estimation. One of these norms uses the principles of cash flow estimation for the process. There are a number of principles of cash flow estimation. These are the consistency principle, separation principle, post-tax principle and incremental principle. The separation principle holds that the project cash flows can be divided in two types named as financing side and investment side. On the other hand, there is the consistency principle. According to this principle, some kind consistency is necessary to be maintained between the flow of cash in a project and the rates of discount that are applicable on the cash flows. At the same time, there is the post-tax principle that holds that the forecast of cash flows for any project should be done through the after-tax method. What is Time Value of Money? Time value of money is the basis of discounted cash flow analysis in finance. It is one of the core principles of small business financing operations. It as to do with interest rates, compound interest, and the concepts of time and risk with regard to money and cash flows. The underlying principle of time value of money is that the value of $1 that you have in your hand today is greater than a dollar you will receive in the future. Time value of money includes the concepts of future value (compounding) and present value (discounting). For example, if you have money in y our hand today, you can save it and earn interest on it or you can spend it now. If you don’t get it until some point in the future, you lose the interest you could earn and you can’t spend it now.
