A clash of cultures :: English Literature

A clash of cultures The two main stories which have a negative end are â€Å"The Train from Rhodesia† and â€Å"The Gold Legged Frog†. Both of these stories include the aspect of â€Å"a clash of culture† which acts as a catalyst for the negative endings. â€Å"The Train from Rhodesia† incorporates the aspect of two cultures from different parts of the world coming together. This story is an allegory and outlines the clash of cultures when white people come into black people’s land and exploit them. The story is about a young couple who are on holiday and they have bought lots of souvenirs. At the platform the young women is attracted to a skilfully carved lion. The young woman doesn’t buy the lion since she thinks that the price is too high. When the train starts to leave the platform the old black man comes running after the train and sells the lion to the young man at half the original price. The young man tells her wife about his success and tries to please her but the young women reacts differently; she is furious at her husband. The young women is angry at her husband for humiliating the old man and making him run after the train, on top of that giving him less than half price for the lion. She feels that the price paid does not reflect the creativity and time spent on carving the lion. An alternative interpretation of this situation could be that the young woman was actually angry at her self. â€Å"The heat of shame mounted through her legs and body and sounded in her ears like the sound of sand pouring†. This quote could mean that the woman was actually angry at her self for not buying the lion at full price in the first place, after all her husband was only trying to please her and didn’t think how he was exploiting the poor black man. In this story symbolism is also a main aspect; â€Å"†¦, and the lion, fallen on its side in the corner.† The lion symbolises the exploitation of black men, emphasises how inferior black man are thought of and that at the end of the day skilful work created by black men is just thrown aside. The writer presents the details of the surroundings and the black people living in poverty through the young woman’s eyes; â€Å"Out of the window, on the other side, there was nothing; sand and bush; a thorn tree.† This strong imagery which we discover through the woman’s eyes means that we feel even more sympathetic towards the black and poor people

Bluetooth Applications

BLUETOOTH APPLICATION ABSTRACT In the current scenario the world is plagued by accidents which are primarily due to human errors in judgment and hence thousands of lives are lost. These accidents can be avoided if only there was a mechanism to alert the driver of approaching danger. This can be done by monitoring the distance between nearby cars and alerting the driver whenever the distance becomes too short. This is precisely the aim of this paper.In this paper we propose the use of Bluetooth Technology by which we can check the speed of the car whenever it comes dangerously close to any other vehicle up front, thereby saving very many lives. CONTENTS: 1. INTRODUCTION 2. ROAD ACCIDENT STATISTICS 3. OPERATION 4. AUTOMATIC BRAKING SYSTEM 5. REPRESENTATION OF OUR IDEA 6. CONCLUSION 7. REFERENCES INTRODUCTION Since Bluetooth devices are capable of communicating with eight other devices simultaneously we can monitor and check the speeds of up to eight cars simultaneously, thus preventing accidents.Thus if we have two Bluetooth enabled devices in two cars the devices automatically communicate with each other when they come in the range of up to 100 meters of each other. The range is dependant on the power class of the product. Power transmission rates vary in many Bluetooth devices depending upon the power saving features available in a particular unit, bandwidth requirements, transmission distance. The statistics of road accidents is tremendous and highlights the need for such a system. The following is a statistic on the number of road accidents occurring each year.ROAD ACCIDENT STATISTICS OF INDIA 1970-2003 | |   |   |   |   |   |   | |Sl. No. | |Source:   Data received from States/UTs. | s OPERATION Because of traveling at high speeds there is a possibility of having accident. The figure 2 shows that when two cars or more come within the distance of 10 km at high speeds there is a possibility of having accidents. The Bluetooth radio is a short dist ance, low power radio operating in the unlicensed spectrum of 2. GHz and using a nominal antenna power of 20 dBm. [pic] At the 20 dB the range is 100 meters, meaning equipment must be Within 100 meters to each other (about 328 feet) to communicate using the Bluetooth standard. With the help of this technology we can send data to the eight devices. The group of eight devices is known as piconet. Here we have a piconet and a scatternet, in the piconet M is the master and S1 to S7 are the slaves [pic] Radio communication is subjected to noise and interference, as the 2. 4 GHz frequencies are shared between the all device in piconet.So the Bluetooth specification has solved this problem by employing what is called as spectrum spreading, in which the Bluetooth radio hops among different frequencies very quickly. There are 79 hops starting at 2. 402 GHz and stopping at 2. 480 GHz, each of which is displaced by 1 MHz. The Bluetooth avoids interference by hoping around these 79 frequencies 1600 times per second. So in order to avoid it we use bluetooth equipped car, in which each car have bluetooth transmitter and receiver. And the every car should have mini computer to monitor the relative position of the car with the other car. pic]When any car comes close together bluetooth device sends warning signal to the car. Based on the type of warning signal received the computer sends signal to the brake control system to slow down the speed of the car. There are two types of control signals. First type of signal control the speed of the car and the second type of signal is to overtake the car which is moving forward. Schematic diagram of car: [pic] AUTOMTIC BRAKE SYSTEM: The automatic brake system is the next generation braking system for controlling the speed of the car.On receiving the control signal from the traveling car the computer inside the car manipulates the signal and gives control signal to the braking system. There are four main components to an automatic brak ing system: †¢ speed sensors †¢ pump †¢ valves †¢ controller [pic] Automatic braking pump and valves The computer constantly monitors the distance between each of these cars and when it senses that the car is getting too close it moves the hydraulic valves to increase the pressure on the braking circuit, effectively increasing the braking force on the wheels.If the distance between two vehicle is within the 100m the Bluetooth devices get enabled and if the distance come closer within 10m the automatic braking system takes the control. After the speed of the car is reduced and distance increased the hydraulic valves decreases the pressure on the braking circuit, thus effectively decrease the braking force on the wheels. The following steps show the various functions of the hydraulic valves: †¢ in position one, the valve is open; pressure from the master cylinder is passed right through to the brake. in position two, the valve blocks the line, isolating that b rake from the master cylinder. This prevents the pressure from rising further should the driver push the brake pedal harder. †¢ in position three, the valve releases some of the pressure from the brake.REPRESENTATION OF OUR IDEA In the figure 7 when car A and car B come within the range of 100m both the Bluetooth devices get enabled and if any one of the car comes too fast then the bluetooth device sends a warning signal to the other car and it processes the signal and gives it to the automatic braking system. pic] CONCLUSION: The Bluetooth technology is being widely adopted by the Industry leaders. The possibility for new applications is very exciting with this Versatile technology. It provides a simple, logical answer to all the Problems-which is built a single common radio into every mobile computer, then neither do companies have to worry about WAN, nor do communication companies need to worry about building external cables. The Bluetooth communication device will thus be a small, low powered radio in a chip that will talk to other Bluetooth enabled products.Bluetooth has been designed to solve a number of connectivity problems experienced by the mobile workers & consumers. Thus, this technology helps make the electronic devices more user friendly and helps address various other problems like accidents. ———————– Fig 1 CAR 1 CAR 6 CAR 4 CAR 3 CAR 7 CAR 8 CAR 5 CAR 2 MINI COMPUTER INSIDE THE CAR Fig 2 M S72222222 S1 M2 S2 S1 M1/S S1 S1/S3 M1 S3 Fig 3 Fig 4 Fig 5 Fig 6 Within 10m Sends warning signal Receives signal and control the speed of car Fig 7

Battle of Corregidor, 1942 - World War II

The Battle of Corregidor was fought May 5-6, 1942, during World War II (1939-1945) and was the last major engagement of the Japanese conquest of the Philippines. A fortress island, Corregidor commanded access to Manila Bay and housed a multitude of batteries. With the Japanese invasion in 1941, American and Filipino forces withdrew to the Bataan Peninsula and Corregidor to await assistance from abroad. While fighting raged along the Bataan line in early 1942, Corregidor served as the headquarters for General Douglas MacArthur until he was ordered to leave for Australia in March. With the peninsulas fall in April, the Japanese shifted their attention to capturing Corregidor. Landing on May 5, Japanese forces overcame fierce resistance before compelling the garrison to capitulate. As part of the Japanese terms, Lieutenant General Jonathan Wainwright was made to surrender all American forces in the Philippines.

MooreColonel Samuel Howard13,000 menJapanLieutenant General Masaharu HommaMajor General Kureo TanaguchiMajor General Kizon Mikami75,000 menCasualties:Allies: 800 killed, 1,000 wounded, and 11,000 capturedJapanese: 900 killed, 1,200 wounded Background Located in Manila Bay, just south of the Bataan Peninsula, Corregidor served as a key element in the Allied defensive plans for the Philippines in the years after World War I. Officially designated Fort Mills, the small island was shaped like a tadpole and was heavily fortified with numerous coastal batteries which mounted 56 guns of various sizes. The wide western end of the island, known as Topside, contained most of the islands guns, while barracks and support facilities were located on a plateau to the east known as Middleside. Further east was Bottomside which contained the town of San Jose as well as dock facilities (Map). Looming over this area was Malinta Hill which housed an array of fortified tunnels. The main shaft ran east-west for 826 feet and possessed 25 lateral tunnels. These housed the offices for General Douglas MacArthurs headquarters as well as storage areas. Connected to this system was a second set of tunnels to the north which contained a 1,000-bed hospital and medical facilities for the garrison (Map). General Douglas MacArthur, 1945. Library of Congress Further to the east, the island tapered to a point where an airfield was located. Due the perceived strength of Corregidors defenses, it was dubbed the Gibraltar of the East. Supporting Corregidor, were three other facilities around Manila Bay: Fort Drum, Fort Frank, and Fort Hughes. With the beginning of the Philippines Campaign in December 1941, these defenses were led by Major General George F. Moore. The Japanese Land Following smaller landings earlier in the month, Japanese forces came ashore in force at Luzons Lingayen Gulf on December 22. Though attempts were made to hold the enemy on the beaches, these efforts failed and by nightfall the Japanese were safely ashore. Recognizing that the enemy could not be pushed back, MacArthur implemented War Plan Orange 3 on December 24. This called for some American and Filipino forces to assume blocking positions while the remainder withdrew to a defensive line on the Bataan Peninsula to the west of Manila. To oversee operations, MacArthur shifted his headquarters to the Malinta Tunnel on Corregidor. For this, he was derisively nicknamed Dugout Doug by the troops fighting on Bataan.

As the campaign progressed, Corregidor first came under attack on December 29 when Japanese aircraft began a bombing campaign against the island. Lasting for several days, these raids destroyed many of the buildings on the island including the Topside and Bottomside barracks as well as the US Navys fuel depot (Map). Preparing Corregidor In January, the air raids diminished and efforts commenced to enhance the islands defenses. While fighting raged on Bataan, the defenders of Corregidor, consisting largely of Colonel Samuel L. Howards 4th Marines and elements of several other units, endured siege conditions as food supplies slowly dwindled. As the situation on Bataan deteriorated, MacArthur received orders from President Franklin Roosevelt to leave the Philippines and escape to Australia. Initially refusing, MacArthur was convinced by his chief of staff to go. Departing on the night of March 12, 1942, he turned over command in the Philippines to Lieutenant General Jonathan Wainwright. Traveling by PT boat to Mindanao, MacArthur and his party then flew to Australia on a B-17 Flying Fortress. Back in the Philippines, efforts to resupply Corregidor largely failed as ships were intercepted by the Japanese. Prior to its fall, only one vessel, the MV Princessa, successfully eluded the Japanese and reached the island with provisions. As the position on Bataan neared collapse, around 1,200 men were shifted to Corregidor from the peninsula. With no alternatives remaining, Major General Edward King was forced to surrender Bataan on April 9. Having secured Bataan, Lieutenant General Masaharu Homma turned his attention to capturing Corregidor and eliminating enemy resistance around Manila. On April 28, Major General Kizon Mikamis 22nd Air Brigade began an aerial offensive against the island. A Desperate Defense Shifting artillery to the southern part of Bataan, Homma began a relentless bombardment of the island on May 1. This continued until May 5 when Japanese troops under Major General Kureo Tanaguchi boarded landing craft to assault Corregidor. Just before midnight, an intense artillery barrage hammered the area between North and Cavalry Points near the islands tail. Storming the beach, the initial wave of 790 Japanese infantry met fierce resistance and was hampered by oil which had washed ashore on Corregidors beaches from the numerous ships sunk in the area. Hospital in the Malinta Tunnel, Corregidor. US Army Though American artillery exacted a heavy toll on the landing fleet, the troops on the beach succeeded in gaining a foothold after making effective use of Type 89 grenade dischargers known as knee mortars. Fighting heavy currents, the second Japanese attack attempted to land further east. Hit hard as they came ashore, the assaulting forces lost most of their officers early in the fighting was largely repulsed by the 4th Marines. The survivors then shifted west to join with the first wave. Struggling inland, the Japanese began to make some gains and by 1:30 AM on May 6 had captured Battery Denver. Becoming a focal point of the battle, the 4th Marines quickly moved to recover the battery. Heavy fighting ensued which became hand-to-hand but ultimately saw the Japanese slowly overwhelm the Marines as reinforcements arrived from the mainland. The Island Falls With the situation desperate, Howard committed his reserves around 4:00 AM. Moving forward, approximately 500 Marines were slowed by Japanese snipers which had infiltrated through the lines. Though suffering from ammunition shortages, the Japanese took advantage of their superior numbers and continued to press the defenders. Around 5:30 AM, approximately 880 reinforcements landed in the island and moved to support the initial assault waves. Four hours later, the Japanese succeeded in landing three tanks on the island. These proved key in driving the defenders back to concrete trenches near the entrance to the Malinta Tunnel. With over 1,000 helpless wounded in the Tunnels hospital and expecting additional Japanese forces to land on the island, Wainwright began to contemplate surrender.

Radioing Roosevelt, Wainwright stated, There is a limit of human endurance, and that point has long been passed. While Howard burned the 4th Marines colors to prevent capture, Wainwright sent emissaries to discuss terms with Homma. Though Wainwright only wished to surrender the men on Corregidor, Homma insisted that he surrender all remaining US and Filipino forces in the Philippines. Concerned about those US forces that had already been captured as well as those on Corregidor, Wainwright saw little choice but comply with this order. As a result, large formations such as Major General William Sharps Visayan-Mindanao Force were forced to surrender without having played a role in the campaign. Though Sharp complied with the surrender order, many of his men continued to battle the Japanese as guerillas. The fighting for Corregidor saw Wainwright lose around 800 killed, 1,000 wounded, and 11,000 captured. Japanese losses numbered 900 killed and 1,200 wounded. While Wainwright was imprisoned in Formosa and Manchuria for the remainder of the war, his men were taken to prison camps around the Philippines as well as used for slave labor in other parts of the Japanese Empire. Corregidor remained under Japanese control until Allied forces liberated the island in February 1945. USS Claxton provides fire support during the Battle of Corregidor (1945).
