Ultrasonic Radar For A Home PC System Essays - Electric Motors

Ultrasonic Radar for a Home PC System One of the fastest changing and most expensive fields, is that of technology. Our computers, printers, modems, and much more is being outdated faster than anything else in the world. Just as we buy a new computer that does what we want, the industry comes out with a new option on a smaller and better computer. There seems to be so much changing that unless we invest our life savings into technology, we are considered obsolete like our computers. What used to fill an entire room, is so small now that it can be swallowed with a glass of milk. A computer used to be a mechanical engine that had many moving parts and was very slow. Now computers design computers that are tenfold their own power and a tenth the size, with less parts and using less power. An airport or an army base used to have huge structures that could send out signals to find out if any aircraft were approaching. This technology is now offered to people who have a computer with microsoft's quick basic, or a Macintosh, and space (equivalent to that of a coffee-pot) to spare. Ultrasonic radar is now a small component for your computer, giving computer operators a chance to see low flying objects, household furniture, and even themselves on their PC screen. Just to impress a neighbour or friend is reason enough to build your own ultrasonic radar station. Similar to that of a Polaroid, ultrasonic transducers are used in this type of radar. A rangefinder emits a brief pulse of high frequency sound that produces an echo when it hits an object. This echo returns to the emitter where the time delay is measured and thus the result is displayed. The Polaroid rangefinder is composed of two different parts. The transducer (Fig. 1) acts as a microphone and a speaker. It emits an ultrasonic pulse then waits for the echo to return. The ranging board is the second part (Fig. 2). This board provides the high voltages required for the transducer, sensitive amplifiers, and control logic. Since R1 is variable it controls the sensitivity of the echo detector. A stepper motor rotates the transducer to get a 360o field of view. For entire assembly see Figure 3. An Experimenter is hooked up to the ranging board to control the ranging board and to measure the round trip time of pulses. It also controls the stepper motor and communicates with the control computer. The connections between the Experimenter, ranging board, and transducer are shown in Figure 4. The ranging board's power requirements are usually under a 100 mA, but at peak transmission the circuit can draw up to 2 Amps of current. Power passes from GND (pin 1) and V+ (pin 9). To avoid malfunction a 300mF or greater should be connected between pin 1 and pin 9 (or alternately pin 16 and pin 5). Another 300mF resistor should be added to the Experimenter end of the cable. Figure 5 shows the timing diagram of the ranging boards's signals. It takes about 360 microseconds to transmit the pulses. The transmitter waits 1 millisecond for the pulse transmission and transducer to complete it's task. Then the experimenter waits for the pulse echo to return. If a pulse is detected the board sets ECHO at high. The Experimenter times the difference between BINH going high to ECHO going high. The experimenter sets INIT to low, waits 0.5 seconds for the echo, if no echo is heard the experimenter cancels the measurement. The measured time is sent to the computer which then calculates, at thousands of calculations per second, the distance based on the speed of sound (1100 feet per second). With a program called DISTANCE.BAS the exact speed of sound can be calculated according to the local weather conditions. The stepper motor is used to rotate the radar so it can scan 360o around the room. An ordinary DC motor would not do for such a project. The rotation must coincide with the emissions and the receptions of the echoes. In a DC motor the armature rotates and the brushes connect successive commuter bars to windings to provide the torque. The speed of this motor depends heavily on how much load there is and how much voltage is applied. A stepper motor has different wires to each winding. By energizing a winding the armature rotates slightly, usually a few degrees. By sequentially charging one winding after another the armature can rotate completely around. By

James Madison, 4th President of the United States

James Madison, 4th President of the United States James Madison (March 16, 1751–June 28, 1836) served as Americas 4th president, navigating the country through the War of 1812. Madison was known as the Father of the Constitution, for his role in its creation, and a man who served during a key time in the development of America.   Fast Facts: James Madison Known For: Americas 4th president and the Father of the ConstitutionBorn: March 16, 1751 in King George County, VirginiaParents:  James Madison, Sr. and Eleanor Rose Conway (Nelly), m. September 15, 1749Died: June 28, 1836 in Montpelier, VirginiaEducation: Robertsons School, College of New Jersey (which would later become Prrinceton University)Spouse: Dolley Payne Todd (m. September 15, 1794)Children: One stepson, John Payne Todd Early Life James Madison was born on March 16, 1751, the eldest child of James Madison, Sr., a plantation owner, and Eleanor Rose Conway (known as Nelly), the daughter of a wealthy planter. He was born at his mothers stepfathers plantation on the Rappahannock River in King George County, Virginia, but the family soon moved to James Madison Sr.s plantation in Virginia. Montpelier, as the plantation would be named in 1780, would be Madison Jr.s home for most of his life. Madison had six brothers and sisters: Francis (b. 1753), Ambrose (b. 1755), Nelly (b. 1760), William (b. 1762), Sarah (b. 1764), Elizabeth (b. 1768); the plantation also held more than 100 enslaved persons. The earliest education of James Madison, Jr. was at home, probably by his mother and grandmother, and at a school located on his fathers plantation. In 1758, he began attending the Robertson School, run by Scottish tutor Donald Robertson, where he studied English, Latin, Greek, French, and Italian, as well as history, arithmetic, algebra, geometry, and geography. Between 1767 and 1769, Madison studied under the rector Thomas Martin, who was hired by the Madison family for that purpose. Education Madison attended the College of New Jersey (which would become Princeton University in 1896) from 1769–1771. He was an excellent student and studied a range of subjects, including oratory, logic, Latin, geography, and philosophy. Perhaps more importantly, he made close friendships at New Jersey, included the American poet Philip Freneau, writer Hugh Henry Brackenridge, lawyer and politician Gunning Bedford Jr., and William Bradford, who would become the second attorney general under George Washington. But Madison grew ill in college, and stayed in Princeton after he graduated until April 1772, when he returned home. He was sickly most of his life, and modern scholars believe he likely suffered from epilepsy. Early Career Madison didnt have a vocation when he left school, but he soon became interested in politics, an interest perhaps stirred but at least fed by his continuing correspondence with William Bradford. The political situation in the country must have been exhilarating: his zeal for freedom from Britain was very strong. His first political appointment was as a delegate to the Virginia Convention (1776), and then he served in the Virginia House of Delegates three times (1776–1777, 1784–1786, 1799–1800). While in the Virginia house, he worked with George Mason to write Virginias constitution; he also met and established a lifelong friendship with Thomas Jefferson. Madison served on the Council of State in Virginia (1778–1779) and then became a member of the Continental Congress (1780–1783). Father of the Constitution Madison first called for a Constitutional Convention in 1786, and when it was convened in 1787 he wrote most of the U.S. Constitution, which outlined a strong federal government. Once the Convention ended, he, John Jay, and Alexander Hamilton together wrote the Federalist Papers, a collection of essays that were intended to sway public opinion to ratifying the new Constitution. Madison served as a U.S. Representative from 1789–1797. On September 15, 1794, Madison married  Dolley Payne Todd,  a widow and socialite who set the pattern for the behavior of White House first ladies for centuries to come. She was a well-liked hostess throughout Jeffersons and Madisons time in office, holding convivial parties with both sides of the Congress in attendance. She and Madison had no children, although John Payne Todd (1792–1852), Dolleys son from her first marriage, was raised by the couple; her son William had died in the 1793 yellow fever epidemic that killed her husband. In response to the Alien and Sedition Acts, in 1798 Madison drafted the Virginia Resolutions, a work that was hailed by anti-federalists. He was secretary of state under President Thomas Jefferson from 1801–1809. Embargo Act and the Presidency By 1807, Madison and Jefferson became alarmed at increasing reports on upheavals in Europe suggesting that Britain would soon go to war with Napoleons France. The two powers declared war and demanded that other nations needed to commit to a side. Since neither the Congress nor the administration were ready for all-out war, Jefferson called for an immediate embargo on all American shipping. That, said Madison, would protect American vessels from almost certain seizure, and deprive European nations of a needed trade that might force them to allow the U.S. to remain neutral. Passed on December 22, 1807, the Embargo Act would soon prove unpopular, an unpopularity that eventually led to U.S. involvement in the War of 1812. In the 1808 election, Jefferson supported Madisons nomination to run, and George Clinton was chosen to be his vice president. He ran against Charles Pinckney, who had opposed Jefferson in 1804. Pinckneys campaign centered around Madisons role with the Embargo Act; nevertheless, Madison won 122 of the 175 electoral votes. Negotiating Neutrality Early in 1808, Congress replaced the Embargo Act with the Non-Intercourse Act, which allowed the U.S. to trade with all nations except France and Great Britain because of the attacks on American shipping by those two nations. Madison offered to trade with either nation if it would stop harassing American ships. However, neither agreed. In 1810, Macons Bill No. 2 was passed, repealing the Non-Intercourse Act and replacing that with a promise that whichever nation would stop harassing American ships would be favored and the U.S. would stop trading with the other nation. France agreed to this and the British continued to stop American ships and impress sailors. By 1811, Madison easily won the renomination for the Democratic-Republicans, despite being opposed by DeWitt Clinton. The campaigns main issue was the War of 1812, and Clinton attempted to appeal to both those for and against the war. Madison won with 128 out of 146 votes. War of 1812: Mr. Madisons War When Madison started his second administration, the British were still forcibly attacking American ships, seizing their cargo, and impressing their sailors. Madison asked Congress to declare war: but support for it was far from unanimous. The war, sometimes called the Second War for Independence (because it resulted in the end of U.S. economic dependence on Britain), pitted a barely prepared U.S. against the well-trained force that was Great Britain. On June 18, 1812, Madison signed a declaration of war against Great Britain, after Congress, for the first time in American history, voted to declare war against another nation. Americas first battle was a disaster called the Surrender of Detroit: The British, led by Major General Isaac Brock, and Native American allies, led by the Shawnee leader Tecumseh, attacked the port city of Detroit on August 15–16, 1812. U.S. Brigadier General William Hull surrendered the town and fort, despite having a larger army. America fared better on the seas, and eventually retook Detroit. The British marched on Washington in 1814, and on August 23 they attacked and burned the White House. Dolley Madison famously stayed in the White House until she ensured that many national treasures were saved. The New England Federalists met at the Hartford Convention in late 1814 to discuss pulling out of the war, and there was even talk of secession at the convention. But, on December 24, 1814, the U.S. and Great Britain agreed to the Treaty of Ghent, which ended the fighting but resolved none of the pre-war issues. Retirement After his presidential term in office ended, Madison retired to his plantation in Virginia. However, he still stayed involved in political discourse. He represented his county at the Virginia Constitutional Convention (1829). He also spoke against nullification, the idea that states could rule federal laws unconstitutional. His Virginia Resolutions were often cited as a precedent for this but he believed in the strength of the union above all. He took a leadership role in the formation of the University of Virginia, especially after Thomas Jeffersons death in 1826. Madison was also a slave owner- Montpelier had 118 slaves at one point- who helped found the notorious American Colonization Society to help resettle freed blacks in what would become Liberia, Africa. Death Although Madison remained vigorous and active during his early retirement, beginning after his 80th birthday in 1829, he began to suffer from longer and longer spells of fever and rheumatism. Eventually he was confined to Montpelier, although he continued working when he could through the winter of 1835–1836. On June 27, 1836, he spent several hours writing a thank you note to George Tucker, who had dedicated his biography of Thomas Jefferson to him. He died the next day. Legacy James Madison was in power at an important time. Even though America did not end the War of 1812 as the ultimate victor, it did end with a stronger and independent economy. As the author of the Constitution, Madisons decisions made during his time as president were based on his interpretation of the document, and he was well-respected for that. In the end, Madison attempted to follow the Constitution and tried not to overstep the boundaries set before him as he interpreted them. Sources Broadwater, Jeff.

Political Socialisation - Essay Example One of the major criticisms against the process of political socialization has been that it adversely affects the large numbers of women in politics and the recent evidences from the politics of world nations substantiate this view. Politics is all about power and power relationships and the people who enjoy power have always been superior in politics. The process of political socialization has the power of defining the relationships among the members of the society and this process decides the matters and topics of political discussions. â€Å"The process of political socialization invariably involves the power to define relationships ‘including the capacity to nominate others as equal or unequal memorable or abject, discusser or the discussed.’ In the social system of the day, men are always regarded as the superior gender that has the potential in determining the course of political and social destinies of a nation and the role of women has been sidelined.

It can be in firms' interests to source components they need from Assignment

It can be in firms' interests to source components they need from competitors. Explain how this can be the case and examine an - Assignment Example The ability to plough back the profits into the business operations gives the firm a competitive advantage over the competitors. Buying of the competitors products may mean the increase in the economies of scale to the firm, which buys the components. This may also come up with the risks associated with the changes in the market structure to torment the operations of the firm (Cennam, & Santalo 2013, pp. 1346-1349) The Benefits When the firm buys the component of the competitor, the firm enjoys vast economies of scale. When the size of the firm increases, the competition wrecks, since the production of the major competitor ids impeded. The competitor the economic scale increases with great efficiency of the firm to solve the huddles of the markets. The costs of operations decrease in the sense that the firm will not at the verge of strong competition to demand a lot in their production mechanism. Being able to control the market gives the firm another heightened advantage as the pric e is set by the major producer of the products. This is further motivated also by the low costs of production that the firm enjoys due to the wide base of economies of scale (Long & Wijeyaratne, 2013. pp. 21). ... More customers would be attracted to the firm’s products. This would attract more customers to buy the firm’s product (Pukeliene & Maksvytiene, 2008. pp. 40). The firm will be able to offer more benefits on its products than the competing products from other firms within the economy. This ability to deliver better services to the customers, improves the firm’s ability to satisfy the growing demands in the contemporary markets (Cummins & Xie, 2013. pp. 151-153). The firm is able to make economic profit margins by having the opportunity to choose from the best alternative due to the diverse products from the firm. The bought components of the competitor can be released to the markets at the firm’s most convenient time. This give the firm the widest base on the opportunity cost (Long & Wijeyaratne, 2013. pp. 80). The markets may demand the products, the firm is at a better position to select on the demanded product, and offer at the firm’s own set pric e. The advantage of the firm to select on the best and readily available product to sell to the market, gives the firm more profits since they sell at their own set prices. When the demand of a given product goes up, the price increases significantly (Dichter & Sala, 2012). This gives the firm an opportunity to sell it at their own set price. This increases the interests of the firm, which it can use to further control the markets based on the wide economies of scale. For example, if the firm decides to release a product, which is highly demanded for to the markets, and the difference in the profits accrued is the opportunity cost. At such a time, the value of the demanded product is higher than the actual value of the other similar products and that of the product itself when the demand is low (Spiller, 2011.

Internal Auditing Concepts for Small and Medium Enterprises

Internal Auditing Concepts for Small and Medium Enterprises INTRODUCTION 1.0 Background Internal auditing is an independent appraisal function established within an organization to examine and evaluate its activities as a service to the organization. It helps an organization accomplish its objectives by bringing a systematic, disciplined approach to evaluate and improve the effectiveness of risk management, control, and governance processes (IIA, 2007). It delivers greater value to an organization by championing good governance, supporting enterprise risk management rollout, consolidating compliance processes, and potentially coordinating various other corporate monitoring functions (Rick Todd, 2008). Corporate governance is a set of processes, controls, and structures generally performed within the organization by, or on behalf of, stakeholders (including the board or other body directly appointed by stakeholders, to ensure that their interests are protected and their goals are achieved (Norman, 2007). Over the past years, there has been a loud call for â€Å"good governance† of organizations (Zeleke, 2007). In the wake of corporate scandals, widespread unethical behavior, and illegal activity in some of the most respected organizations, corporate governance has become important in both public and private organizations (Tumuheki, 2007). These accounting scandals and legislation highlight the critical role the internal audit function plays in corporate governance (Deborah et al, 2008). It is therefore not surprising that the Institute of Internal Auditors (IIA) puts a lot of effort in guiding its members to become corporate governance specialists, capable to assist both management and the board (Jan, 2005). Uganda, like other transition economies, now increasingly recognizes that corporate governance is an essential tool for prosperity and economic growth. (Tumuheki, 2007). For Small and Medium Enterprises, especially those with a serious desire to grow and perhaps someday get stock exchange listings of their own, they should consider adopting key elements of corporate governance as this will help them gain access to information and resources for growth. The presence of proper accounting and bookkeeping practices increases confidence in SMEs and makes them less risky to invest or finance. According to Wee Teck (2003), there has been a recent growing call for the application of corporate governance to SMEs. They argue that, corporate governance has similar benefits to SMEs as to listed companies and therefore similar guidelines that apply to listed companies should also be applicable to SMEs. 2.0 Statement of the Problem Small and Medium Enterprises (SMEs) are critical for Uganda because of their role in economic growth and poverty reduction. A dynamic and vibrant SME sector will provide sustainable growth, generate jobs and therefore reduce poverty levels .As companies globally face issues relating to transparency, accountability and timely disclosure of material information, the concept of corporate governance and business ethics in SMEs has gained significant importance (Shahnawaz, 2003). In Uganda, SMEs which form 90% of the private sector, lack organised in-house procedures to manage and supervise internal controls, risk management, business performance and cash flows. This has caused a high collapse rate, with 40 % failing within one year and 80 % within five years (Kasule, 2008) despite the high formation rate. This has prompted me to look at the relationship between internal audit proficiency and corporate governance in the small and medium scale enterprises in Uganda. 3.0 Purpose of the Study The purpose of the study seeks to evaluate the relationships between internal audit proficiency and internal controls; internal controls and corporate governance; internal audit proficiency and risk management; internal controls and risk management; and risk management and corporate governance in Ugandas SMEs. 4.0 Objectives of the Study The specific objectives of the study are stated below: i To establish the relationship between internal audit proficiency and internal controls in SMEs ii To establish the relationship between internal control systems and corporate governance in SMEs iii To establish the relationship between internal audit proficiency and risk management in SMEs iv To establish the relationship between internal controls and risk management in SMEs v To establish the relationship between risk management and corporate governance in SMEs. 5.0 Research Questions i) What are the causes of lack of internal audit proficiency in Ugandas SMEs? ii) What role can internal audit proficiency play to promote good corporate governance in Ugandas SMEs? 6.0 Scope of the Study The study will focus on internal audit proficiency, internal controls, risk management and corporate governance practices in Ugandas SMEs. It will be conducted within Kampala District since Kampala area has the largest number of SMEs in Uganda. The SMEs will be studied under the following categories; trade and commerce, service and manufacturing. 7.0 Significance of the Study The study will benefit the SME sector since it will highlight areas of emphasis that they should take advantage of. Scholars and academicians may be inspired to carry out further studies based on these findings. The study is expected to boost the literature gap on internal audit and corporate governance in the SME sector. Policy makers and other stakeholders will benefit from the findings of this research since they will be able to draw conclusions based on the findings. 8.0 Conceptual Framework The conceptual frame work draws upon the works of Faudziah et al, (2005), Laura Michael, (2002) and Tushabomwe (2006) with adjustments made to fit SMEs in Uganda. It explores the relationship between two variables; internal audit proficiency and corporate governance in Ugandas SMEs. According to Gerrit Ignace (2006), internal controls more specifically and risk management have been considered fundamental elements of organizational governance and that, it is the job of internal auditors to help organisations accomplish their objectives by bringing systematic and disciplined approaches to evaluate and improve the effectiveness of risk management, control and governance processes. Internal auditors have an important role in the corporate governance process (Jan, 2007) and therefore need to be out in front, leading organisations with regards to the internal control systems and also focusing on strategic business objectives. They also need to establish themselves as vital cogs in their organizations, rather than as observers who watch from the periphery and wait for events to impact them (Sawyer Vinten, 1996). Therefore their experience and skill in carrying out audit work is of great importance since constructive advice to the Board and management adds value to organizations. The following conceptual frame work will be used to guide the study.

His Excellency George Washington

His Excellency George Washington His Excellency George Washington, written by Joseph J. Ellis, provides us a look at one of the most influential men in American history. However, instead of looking at the monumental titan as most did, Ellis wrote about the man behind the monument; his successes, failures and desires that few if any have written about before.While not as formal sounding to the reader with many questions and out of the way comments by the author based on opinion instead of fact, like on page 194 where in moment about Washington saying formal etiquette of the levees combined with Washington's natural dignity (or was it his aloofness? ) to create†¦. ‘ with the content in the parentheses being his own. This statement of his was neither followed up by any fact nor further discussion entirely which is necessary in these situations. Or is it?Ellis spent his book not focusing on the monolith but on the man, dating back to before the French and Indian war where Wash ington started to receive recognition for his services, to his death in 1799. Ellis looked past all the brass and silver of his success in the public and thoroughly explored his private and personal life. Ellis painted Washington as a man who focused intently on his bottom line, as seen on page 165 where Ellis describes that the main reason for Washington wanting to get rid of his slaves was not for moral reasons but for economic reasons, as the slaves were no longer worth the investment.Ellis harped on the fact that only 3 letters of correspondence survived between George and Martha Washington (page 42), which was one of the few times e released his emotions considering his natural stone exterior. Ellis also put considerable effort in to focusing on his home in Mount Vernon which was a centerpiece in Washington's life. His life was changed forever by his wife Martha who, even though they originally married for economic reasons, became a ‘mutually affectionate bond' (Ellis, 42 ). From the beginning Washington was concerned about his future in the aristocratic- like planter class of Virginia.Being the 2nd son in the family George was not slated to receive his father's fortune, so he would need to find another career where he could aka one. He got his first Job as a surveyor sent to check on land in the Shenandoah Valley (Ellis, 10). It is presumed by Ellis that this is the point at which Washington saw the expansive and untouched land to the west, a driving force behind his ambitions both at the start of the revolution (Ellis, 57) and during his presidency. During his youth, America was a land where most identified themselves as British, Virginian ‘army and worked alongside the British intently during the French and Indian war.However many of the colonists believed they fought the French and Indian war to be allowed to expand west. This thought was extinguished when the proclamation of 1763 was released, forbidding colonist expansion westward. This w as one of the starting points where colonists began to feel some resentment to the British Crown, and only snowballed with every act thereafter. As more taxes and acts were being placed on colonists more and more anger about a lack or representation in parliament began to seep into American politics.Many of the more radical members who wanted full separation/retaliation became to be known as the Whig arty (Ellis, 62). These Whig were inspired by the Country Party (Ellis, 62-63) of England and wanted to establish a republican like government that better represented the colonists in the Americas. As time went on and the revolution ended, while the framing of the constitution took place and there on after, 2 political parties in the United States began to take route. The first major group was the Federalists led by Alexander Hamilton which Washington was a supporter of.The Federalists are precursors to modern day republicans. On the other hand a large group of people in the south didn' t like the centralist ideas of the Federalists, fearing that the Federalists would destroy their agriculturally based economies (Ellis, 204-205). These men went on to form the Republican Party, or Anti-Federalists, which is the modern precursor to the Democratic Party. While a member of it Washington hated and despised these 2 parties as he feared it would lead to a deadlock (which we can see today). Many decisions that would affect Americas social future were decided in Washington's era.A large one, the legality of slaves was one that was with him from the time of the revolution where he considered offering freedom for those who fought for him, until he finally passed away (Ellis, 263). While personally against slavery from a moral stand point later in his life at the beginning he took advantage of slave labor to help create his massive estates that were pivotal to his position in Virginia society. He did have 1 condition however that most slave owners didn't have; he would never s ell members of a slave family, only the whole family together (Ellis, 258).Joseph J. Ellis created a biography that changed some perspective of Washington. No longer an immovable figure of greatness, he was portrayed as a man who went through hardships, strife, and success, while still keeping his goals and ideals alive. He was a man with a deep capacity for emotion who had learned self-control and was always looking towards the future. He saw George as a man who would do what it took to get the Job done, and extend his legacy forever. Most importantly, Ellis shed new light on the man and not the monolith of His Excellency George Washington.

Macbeth Theme

One of the most fascinating ways in which Shakespeare explores the theme of appearance and reality is through the characters of the witches. The witches bring with them confusion, which infects the natural order. Night becomes day. Duncan’s horses eat each other, Fair is foul, and foul is fair. This quote is fairly early in the text, and sets the tone for the rest of the play. It alludes to the deceptive nature of the play, referring to the idea that things are not always as they seem.The quote itself foreshadows the apparent sinister and deceitful nature of the play, in that it brings forth the idea that things that seem fair, good and true may well in fact be evil or foul. Likewise, things that appear evil may possess elements of good in them. This quote is a key component of the play, as the play itself centres around the idea of deception and that what appears on the outside is not always a true reflection of what lies beneath,. the course of the play, they lead to greater confusion in Macbeth’s mind.They seem to promise him good things, but his life subsequently begins to deteriorate. On the night of the murder, Macbeth sees a floating dagger, but can not decide if this â€Å"air-drawn dagger† is real or a figment of his imagination proceeding from his â€Å"heat-oppressed brain†. His confusion between what is real and what is not seems to increase as the witches’ influence over Macbeth grows. As Macbeth’s actions become more tyrannical and savage, the strain of hiding their (Macbeth and Lady Macbeth’s) true nature surfaces. The pair quickly begins to lose their grip on reality.Following Banquo’s murder, Macbeth sees his ghost at the feast. Macbeth has lost the ability to differentiate between appearance and reality. The cause behind Macbeth’s murder of Banquo was his inability to accept anything at face-value. Macbeth turns to the witches when he begins to become â€Å"cribb’d and conf ined†. These are the very â€Å"hags† behind Macbeth’s original confusion. They very quickly bring Macbeth into a state of mind where he becomes totally disconnected from reality. He takes the witches apparitions and predictions literally, believing that he is safe from any harm.The prediction that Macbeth will be safe until â€Å"Birnam Wood reaches Dunsinane† appears to indicate that he will not be threatened any time in the near future.
