"She's just another Hollywood whore, an immoral porn queen. She's beyond redemption," he muttered to himself as he paced back and forth outside her apartment building. He had been constantly walking around outside the building for hours now, harassing people passing on the streets with crazed questions. Suddenly, overcome with resolve, the man stomped back to the building and rang the bell. She had rejected him once, but never again. He had given her a chance, but she had turned him away from her life. How could she do this to him, her biggest fan? After letting go of the buzzer, Robert Bardo hid himself in the bushes by the door. This was the only choice he had left after such a rejection. Twenty-one year old Rebecca Schaeffer, actress on the sitcom My Sister Sam, answered the door for the last time in her life. She had politely turned away a disturbing man earlier that day after explaining to him that she had to study her lines for her next show. However, when she answered the door this time, there was no one there. Bardo saw his chance and acted on it. He burst from the shadowy confines of the bushes and pushed a gun into Schaeffer's chest, pulling the trigger after he had her in his grasp. The bullet barely missed the young actress's heart as she fell to the ground, bleeding from a mortal wound. As Bardo flew from the scene, he stashed the incriminating evidence into the bushes. After interrogations performed by the LAPD, it was found that Bardo had been stalking Schaeffer for a very long time. However, this was not the usual case of a voyeur or a stranger trailing someone throughout their day. Bardo had traced Schaeffer through the use of the computer and its vast resources. With the use of computer databases, Bardo was able to find out where Schaeffer lived, what her telephone number was and who she called, what kind of vehicle she drove, and where she spent her money. It was as if Bardo could look through a window and clearly see all of Schaeffer's personal, intimate secrets (Rothfeder 13-14).This is the perfect example of a modern crime, in which all of an individual's privacy and personal information have become little more than a commodity, easily accessible to anyone with very little hassle. In the highly modernized society in which everyone lives, people compromise their privacy in order to live comfortably.

The Three Stages of Alzheimers Essay -- Alzheimers Disease Essays

Alzheimer’s is most likely formed by other symptoms called dementia. Dementia is not an actual disease, but has a vast range of symptoms which are precursors to many types of diseases. When dementia is detected in an individual their memory tends to decline and it becomes a hassle to complete everyday duties. When diagnosing individuals there are a series of steps taken in order to see if the individual progressed to dementia and also which disease caused those symptoms to take effect. These stages are preclinical, mild cognitive impairment (MCI) and dementia. Within the preclinical stage there are three sub-stages that deal with protein, plaque buildup in the brain called beta-amyloid. The symptoms for this stage are undetectable. Stage two is the MCI stage, which contain more visible symptoms such as deterioration of thinking abilities. Stage three is dementia. The symptoms for this stage are more severe and researchers use biomarkers (biochemical trackers) to detect the dis ease. There have been questions on whether individuals diagnosed with MCI are more likely to stop at dementia or progress towards Alzheimer’s disease. There have been a couple of experiments pertaining to this question, however people diagnosed with mild cognitive impairment (MCI) tend to pass the third stage, which is dementia and progress towards Alzheimer’s. When a person is diagnosed with a certain health problem, it doesn’t come within a matter of seconds, it happens within a steady process. First there are symptoms which most people ignore until diagnosis, then after a couple of years of ignoring the symptoms that person is diagnosed. Minor symptoms could start with slight memory loss that could result in, for example, misplacing car keys and forgett... ...the individuals mental abilities start to slow down. Lastly, stage three dealt with dementia. Within this stage the cognitive functions start shutting down. Researchers diagnose individuals with this stage and test whether they have progressed into Alzheimer’s disease. The detection of Alzheimer’s disease is easier for the researchers to detect because the symptoms are noticeable and their cognitive and behavior changes for the worst. These individuals start having mood swings and obsessive compulsion disorder and unacceptable social behavior. Referring back to the BMC Neurology research experiment, it showed that 54 individuals were diagnosed with Dementia and 50 individuals progressed to Alzheimer’s disease. This concludes that people diagnosed with mild cognitive impairment (MCI) tend to pass the third stage, which is dementia and progress towards Alzheimer’s.

In Electricity Generation, an Electric Generator Is a Device

Electric generator In  electricity generation, an  electric generator  is a device that converts  mechanical energy  to  electrical energy. A generator forces  electric charge  (usually carried by  electrons) to flow through an external  electrical circuit. It is analogous to a  water pump, which causes water to flow (but does not create water). The  source of mechanical energy  may be a reciprocating or turbine  steam engine, water falling through a  turbine or waterwheel, an  internal combustion engine, a  wind turbine, a hand  crank,  compressed air  or any other source of mechanical energy.The reverse conversion of electrical energy into mechanical energy is done by an  electric motor, and motors and generators have many similarities. In fact many motors can be mechanically driven to generate electricity, and very frequently make acceptable generators. ———-Historical developments Before the connection between  magne tism  and  electricity  was discovered,  electrostatic generators  were invented that used  electrostaticprinciples. These generated very high  voltages  and low  currents.They operated by using moving  electrically charged  belts, plates and disks to carry charge to a high potential electrode. The charge was generated using either of two mechanisms: * Electrostatic induction * The  triboelectric effect, where the contact between two insulators leaves them charged. Because of their inefficiency and the difficulty of  insulating  machines producing very high voltages, electrostatic generators had low power ratings and were never used for generation of commercially significant quantities of electric power.The  Wimshurst machine  and  Van de Graaff generator  are examples of these machines that have survived. Faraday's disk In the years of 1831–1832,  Michael Faraday  discovered the operating principle of electromagnetic generators. The pr inciple, later calledFaraday's law, is that an  electromotive force  is generated in an electrical conductor that encircles a varying  magnetic flux. He also built the first electromagnetic generator, called the  Faraday disk, a type of  homopolar generator, using a  copper  disc rotating between the poles of a horseshoe  magnet. It produced a small DC voltage.This design was inefficient due to self-cancelling counterflows of current in regions not under the influence of the magnetic field. While current was induced directly underneath the magnet, the current would circulate backwards in regions outside the influence of the magnetic field. This counterflow limits the power output to the pickup wires and induces waste heating of the copper disc. Later homopolar generators would solve this problem by using an array of magnets arranged around the disc perimeter to maintain a steady field effect in one current-flow direction.Another disadvantage was that the output volta ge was very low, due to the single current path through the magnetic flux. Experimenters found that using multiple turns of wire in a coil could produce higher more useful voltages. Since the output voltage is proportional to the number of turns, generators could be easily designed to produce any desired voltage by varying the number of turns. Wire windings became a basic feature of all subsequent generator designs. Dynamo The  dynamo  was the first electrical generator capable of delivering power for industry.The dynamo uses  electromagnetic  principles to convert mechanical rotation intopulsed DC  through the use of a  commutator. The first dynamo was built by  Hippolyte Pixii  in 1832. Through a series of accidental discoveries, the dynamo became the source of many later inventions, including the DC  electric motor, the AC  alternator, the AC  synchronous motor, and the  rotary converter. A dynamo machine consists of a stationary structure, which provides a constant magnetic field, and a set of rotating windings which turn within that field.On small machines the constant magnetic field may be provided by one or more permanent magnets; larger machines have the constant magnetic field provided by one or more electromagnets, which are usually called field coils. Large power generation dynamos are now rarely seen due to the now nearly universal use of  alternating current  for power distribution and  solid state  electronic AC to DC power conversion. But before the principles of AC were discovered, very large direct-current dynamos were the only means of power generation and distribution.Now power generation dynamos are mostly a curiosity. Alternator Without a  commutator, a dynamo becomes an  alternator, which is a  synchronous singly fed generator. When used to feed anelectric power grid, an alternator must always operate at a constant speed that is precisely synchronized to the electrical frequency of the power grid. A D C generator can operate at any speed within mechanical limits, but always outputs direct current. Typical alternators use a rotating field winding excited with direct current, and a stationary (stator) winding that produces alternating current.Since the rotor field only requires a tiny fraction of the power generated by the machine, the brushes for the field contact can be relatively small. In the case of a brushless exciter, no brushes are used at all and the rotor shaft carries rectifiers to excite the main field winding. MHD generator Main article:  MHD generator A magnetohydrodynamic generator directly extracts electric power from moving hot gases through a magnetic field, without the use of rotating electromagnetic machinery. MHD generators were originally developed because the output of a plasma MHD generator is a flame, well able to heat the boilers of a  steam  power plant.The first practical design was the AVCO Mk. 25, developed in 1965. The U. S. government funded su bstantial development, culminating in a 25 MW demonstration plant in 1987. In the  Soviet Union  from 1972 until the late 1980s, the MHD plant U 25 was in regular commercial operation on the Moscow power system with a rating of 25 MW, the largest MHD plant rating in the world at that time. [2]  MHD generators operated as a  topping cycle  are currently (2007) less efficient than combined-cycle  gas turbines. ————————————————- Terminology The two main parts of a generator or motor can be described in either echanical or electrical terms. Mechanical: * Rotor: The rotating part of an  electrical machine * Stator: The stationary part of an electrical machine Electrical: * Armature: The power-producing component of an electrical machine. In a generator, alternator, or dynamo the armature windings generate the electric current. The armature can be on either the rot or or the stator. * Field: The magnetic field component of an electrical machine. The magnetic field of the dynamo or alternator can be provided by either electromagnets or permanent magnets mounted on either the rotor or the stator.Because power transferred into the field circuit is much less than in the armature circuit, AC generators nearly always have the field winding on the rotor and the stator as the armature winding. Only a small amount of field current must be transferred to the moving rotor, using  slip rings. Direct current machines (dynamos) require a  commutator  on the rotating shaft to convert the  alternating current  produced by the armature to  direct current, so the armature winding is on the rotor of the machine. ————————————————- ExcitationAn electric generator or electric motor that uses field coils rather than permanent magnets requires a current to be present in the field coils for the device to be able to work. If the field coils are not powered, the rotor in a generator can spin without producing any usable electrical energy, while the rotor of a motor may not spin at all. Smaller generators are sometimes  self-excited, which means the field coils are powered by the current produced by the generator itself. The field coils are connected in series or parallel with the armature winding.When the generator first starts to turn, the small amount of  remanent magnetism  present in the iron core provides a magnetic field to get it started, generating a small current in the armature. This flows through the field coils, creating a larger magnetic field which generates a larger armature current. This â€Å"bootstrap† process continues until the magnetic field in the core levels off due to  saturation  and the generator reaches a steady state power output. Very large power station generators often utilize a separate smaller generator to excite the field coils of the larger.In the event of a severe widespread  power outage  where  islanding  of power stations has occurred, the stations may need to perform a  black start  to excite the fields of their largest generators, in order to restore customer power service. ————————————————- Equivalent circuit The equivalent circuit of a generator and load is shown in the diagram to the right. The generator's  VG  and  RG  parameters can be determined by measuring the winding resistance (corrected to operating temperature), and measuring the open-circuit and loaded voltage for a defined current load. ———————————————— [edit]Vehicle-mounted generators Early motor vehicles until about the 1960s tended to use D C generators with electromechanical regulators. These have now been replaced byalternators  with built-in  rectifier  circuits, which are less costly and lighter for equivalent output. Moreover, the power output of a DC generator is proportional to rotational speed, whereas the power output of an alternator is independent of rotational speed. As a result, the charging output of an alternator at engine idle speed can be much greater than that of a DC generator.Automotive alternators power the electrical systems on the vehicle and recharge the  battery  after starting. Rated output will typically be in the range 50-100 A at 12 V, depending on the designed electrical load within the vehicle. Some cars now have electrically powered  steering assistance  and  air conditioning, which places a high load on the electrical system. Large commercial vehicles are more likely to use 24 V to give sufficient power at the  starter motor  to turn over a largediesel engine.Vehicle alternators do not use permanent magnets and are typically only 50-60% efficient over a wide speed range. [4]Motorcycle alternators often use permanent magnet  stators  made with  rare earth  magnets, since they can be made smaller and lighter than other types. See also  hybrid vehicle. Some of the smallest generators commonly found power  bicycle lights. These tend to be 0. 5 ampere, permanent-magnet alternators supplying 3-6 W at 6 V or 12 V. Being powered by the rider, efficiency is at a premium, so these may incorporate  rare-earth magnets  and are designed and manufactured with great precision.Nevertheless, the maximum efficiency is only around 80% for the best of these generators—60% is more typical—due in part to the rolling friction at the  tyre–generator  interface from poor alignment, the small size of the generator, bearing losses and cheap design. The use of permanent magnets means that efficiency falls even further at high speed s because the magnetic field strength cannot be controlled in any way. Hub dynamos  remedy many of these flaws since they are internal to the bicycle hub and do not require an interface between the generator and tyre. Until recently, these generators have been expensive and hard to find.Major bicycle component manufacturers like Shimano and SRAM have only just entered this market. However, significant gains can be expected in future as cycling becomes more mainstream transportation and LED technology allows brighter lighting at the reduced current these generators are capable of providing. Sailing yachts may use a water or wind powered generator to trickle-charge the batteries. A small  propeller,  wind turbine  or  impeller  is connected to a low-power alternator and rectifier to supply currents of up to 12 A at typical cruising speeds. Still smaller generators are used in  micropower  applications. ————————â⠂¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€ Engine-generator An  engine-generator  is the combination of an electrical generator and an  engine  (prime mover) mounted together to form a single piece of self-contained equipment. The engines used are usually piston engines, but gas turbines can also be used. Many different versions are available – ranging from very small portable  petrol  powered sets to large turbine installations. ————————————————- Human powered electrical generators A generator can also be driven by human muscle power (for instance, in field radio station equipment).Human powered direct current generators are commercially available, and have been the project of some  DIY  enthusiasts. Typically operated by means of pedal power, a converted bicycle trainer, or a foot pump, such generators can be practically used to charge batteries, and in some cases are designed with an integral inverter. The average adult could generate about 125-200 watts on a pedal powered generator, but at a power of 200 W, a typical healthy human will reach complete exhaustion and fail to produce any more power after approximately 1. 3 hours. 6]Portable radio receivers with a crank are made to reduce battery purchase requirements, see  clockwork radio. During the mid 20th century, pedal powered radios were used throughout the Australian outback, to provide schooling,(school of the air) medical and other needs in remote stations and towns. ————————————————- Linear electric generator In the simplest form of linear electric generator, a sliding  magnet  moves back and forth through a  solenoid  Ã¢â‚¬â€œ a spool of copper wire. Analternating current  is induced in the loops of wire by  Faraday's law o f induction  each time the magnet slides through.This type of generator is used in the  Faraday flashlight. Larger linear electricity generators are used in  wave power  schemes. ————————————————- Tachogenerator Tachogenerators are frequently used to power  tachometers  to measure the speeds of electric motors, engines, and the equipment they power. Generators generate voltage roughly proportional to shaft speed. With precise construction and design, generators can be built to produce very precise voltages for certain ranges of shaft speeds

Humans And Technology: Partners In The Future Essay

With the rate that technology is constantly improving many question the state of humans in the future when technology might possibly overtake human development. However, those who believe that the future is a place where humans will be enslaved by technology and man will no longer be enjoying the liberties now enjoyed might be in for a surprise because technology is currently designed to assist humans and improve the human quality of life. Humans and technology are set to become partners in the future because man created technology for his advancement and advantage, technology was designed to support human existence and technology was designed to improve life. The first programmable computer was invented in 1938 which was followed by the development of many other types of computers through the years. (ComputerHope) For many, this was the beginning of technology; but the fact remains that technology is the use of existing materials to improve or enhance the performance of a particular task. So based on this concept of technology, then such a concept existed as early as the time that man discovered the use of fire or when the Chinese first developed the wheel. Technology has been around for ages and for all of these instances its objective was to make the performance of a task easier. This means that the task performed is done by a human and the addition of technology simply makes the task performed by the said human much is easier to do. Technology was never intended to replace humans because it is there to exist side by side with its creator to assist in and to enhance the performance of a task. On this premise, it is easy to gather evidence that in fact, in the future, humans and technology are set to become partners to ensure the efficient and effective delivery of many things from services to products, and to the more mundane conveniences in life. One proof that humans and technology are most likely to become mutual partners in the future is the fact that technology is created for the advancement or advantage of man. Robotics is one of the aspects of technology that proves this particular point. There are suppositions that â€Å"the accelerating pace of technological change allows us to build machines like cyborgs (machine-enhanced humans like the Six Million Dollar Man), androids (human-robot hybrids like Data in Star Trek) and other combinations beyond what we can even imagine. † (Carnett) These innovations in robotics are set to blur the distinction between man and machine, making man perform in ways that are beyond what one can conceive. With robotics man will be able to raise a two hundred pound weight as easily as a forklift. Mike Harden once commented that, â€Å"in robotics, I want to do it. It’s because I’m a magically different person in robotics. † (2010) Such a comment simply shows how this kind of technology can improve even the way humans view themselves in the context of technology – that man is empowered by technology and technology exists merely as a means of improving what man is able to normally do. Robotics is the best evidence that technology simply exists to make tasks easier for humans. This fact is validated by current situations where â€Å"Robots already perform many [dangerous] functions, from making cars to defusing bombs or firing missiles. (Singer and Sagan) These tasks can be lethal to humans and with the purpose of keeping humans away from risky situations, robots are utilized. Which brings the discussion to the second proof that in the future humans and technology are bound to become mutual partners – the technological purpose of human life support. Technology is designed to support human existence which is why it cannot be perceived as something that will ultimately destroy and/or cause the extinction of the human race. Medicine is the field of science where technology ultimately plays a role in supporting the existence of human life. For instance, â€Å"Dr. Howard W. Jones Jr. , the surgeon, along with his wife, Dr. Georgeanna Seegar Jones, helped to create the first test tube baby born in the United States† (Epstein) These scientists insist that human reproduction is not as efficient as it would first seem to be so technology needs to assist humans in the matter of procreation. Epstein) This basically shows the purpose of such a controversial technological advancement as ‘in vitro fertilization’ is not to smite the laws of nature or to cause the extinction of the human race but on the contrary, to support such existence so that reproduction will be more efficient when compared to natural reproduction which can be affected by other, more risky influences and may result to abnormal conception or childbirth. Even scientists who are involved in such questionable technological advances like cloning accept and concede to the belief that even these kinds of scientific procedures are intended for the betterment of future generations, hence, Dr. Margaret McLean (2010) asserts that, â€Å"The question is not whether we ought to ban or applaud cloning but why would we choose to go forward and whether our choices bode well or ill for present and future children and our relationships with them. (Sterns) This basically shows how scientists themselves agree to the role of technology in terms of ensuring and supporting the existence of the human race. This particular belief is connected to how technology is able to improve and enhance the quality of life of human beings. From the ordinary toaster to the microwave oven to the more complex capabilities of the newest models of cellular phones intended for mobile communication, the future of technology is quite clear to be a future where humans will most likely live better lives because of how innovations can make life easier and more convenient. However, these are merely the superficial and tangible representations of such a future; other, more complex studies and more world-shattering innovations are on their way. One such innovation can be found in genetics. The most amazing developments in this field can be seen in the development of gene therapy and genetic engineering. â€Å"Gene therapy has very real potential for enhancing human health† (Adams) because it addresses the flaws in human genes and corrects these flaws thereby remedying whatever physical or physiological problems are caused by that particular damaged gene. Considering this capability of gene therapy, then it is not strange if one day a diabetic is able to eat as much sugar as he/she wants to or a hypertensive is able to smoke as much as he/she wants. These effects are the perceived effects of gene therapy where the gene that causes the illness or the ailment is corrected and reintroduced into the human body. Another implication of genetics is in agriculture where food can be genetically engineered resulting in bigger tomatoes, cholesterol-free swine, and eggs or nuts that do not have any allergens! Therefore, â€Å"Plant science and plant gene technology will be critical activities of the nation’s response to many challenges it faces in the coming decades† (AAS) These challenges include the resolution of hunger, the provision of healthier food alternatives, and the sustainability of food stores for all the people in the world. Obviously, as is illustrated in these examples, technology is set to make the lives of humans more convenient. The standard of living for humans will increase with technology taking headway into the future. This particular aspect of technology is hard evidence that in the future, technology will be a partner of human beings in making the world a better place to live in. The fallacy of machines dominating humans in the future and the development of super-intelligences that will overtake human intelligence is, at this point, science fiction, because as circumstances show, technology is doing nothing nowadays but assisting humans and making life easier. The image of humans being chained by robots and made to do their bidding or used as fodder for their cogs and screws is an image that will hopefully remain in literature as the future of technology is bright in the context of how it can assist humans and improve and enhance human life. Partnership means having mutual benefit not merely focusing on the benefits of one party and in the case of technology, the benefits are both ways. The future is when humans will get as much from technology as technology from humans because without humans, technology will remain static and will no longer move onward in development. Evidence shows that as technology moves further away from the discovery of fire and the modeling of the wheel humans are set to enjoy the future with technology as an indispensable partner. Recent advancements in various fields such as robotics, genetics, medicine, and other fields of science have showed that technology will most likely be a partner to humans in the future because technology serves to make human life more convenient, it exists to support human existence, and it is designed to improve the human quality of life. Technology, while seemingly threatening to some, is in fact moving toward a fruitful and productive partnership with the human race not far into the twentieth century.

Discussion board Assignment Example | Topics and Well Written Essays - 250 words - 1

Discussion board - Assignment Example The Hounds of Baskerville do not conform to Dine’s rules concerning this rule. This is because the audience was not given the chance to solve the mysterious death of Sir Charles. In addition, Dine proposes that the writer must not play tricks on the readers. Criminals, however, can trick detectives. With respect to this rule, Doyle conforms as he got Jack tricking Holmes until the last minutes. Dine also purports that detective stories should not have romance. Doyle breaks this rule by introducing Beryl to Sir Henry’s life. Their affairs occur despite Beryl being Jack’s wife. Failure to conform to this rule strengthens the story since Beryl later on warns Henry of Jacks intentions. The criminal in Hounds of Baskerville was discovered by logic deduction as opposed to accidental or coincidental circumstances. Doyle also conformed to other Dine rules including lack of supernatural solutions, presence of only one detective who must solve the crime. In addition, the c rime must be murder, and the murderer must be familiar to readers. Doyle’s concentration on plot and development of only Sherlock and Watsons’s characters is a strategy that complies with Dine’s twenty detective story rules. This bias functions to eliminate deviations from the story. Doyle provides character description that is efficient for readers’

The Lewis and Clark Expedition Essay Example | Topics and Well Written Essays - 1000 words

The Lewis and Clark Expedition - Essay Example The main objective of the expedition thus was stated as to â€Å"Explore the Missouri river & such principal stream of it as by its course and communication with the waters of the Pacific ocean, whether the Columbia, Oregon, Colorado or any other river may offer the most direct & practicable water communication across this continent for the purpose of commerce† (Presidential Mission 2001). Led by Captain Meriwether Lewis and Lieutenant William Clark, the historic expedition was given the name Corps Of Discovery. Exploring the history surrounding the expedition, it is worth understanding what prompted the American government in to commissioning this exploration. During the late seventeen hundreds, the French had been thinking of sending an expedition to explore the western part of the continent. President Thomas Jefferson, who was then the minister to France (1785-1789), heard many rumors of such expeditions. Although the French maintained that the expedition planned was purely on the basis of scientific interest and not of commercial motives, many had their doubts. Whatever the intentions may have been, the initial French expedition of 1788 was not a success as it was halted due to bad weather conditions (Lewis & Clark Expedition 2007). It’s most likely that President Thomas Jefferson’s interest in initiating the expedition once he became president was influenced to some degree by the knowledge of French interest in the matter. In addition, in 1786 an American, John Ledyard planned of crossing the Continent from the western side itself. The route was planned to be overland across Siberia all the way to the Capital. This expedition failed half way as Czarina, Catherine The Great of Russia had him deported to Poland once he arrived in Siberia. Subsequently, the Louisiana Purchase renewed the interest in exploring the west, and it also made the expedition more politically correct as the American
