IELD LAW - Essay Example Acemoglu goes on to say that it is important to obtain the right balance between politics and economics, because one inadvertently affects the other (Acemoglu 68). This is where law comes in because laws and policies are mainly made by politicians; these are the same laws that have major effects on the economy and development of a country. As a result of this, it is really important that a right mix be found between politics (law) and economics; this will create new opportunities and freedoms which can be exploited in order to improve economies and by extension the living standards of people living in poor countries (Acemoglu 69). In his book, The End of Poverty: Economic Possibilities for Our Time, Sachs provides several reasons why some countries fail to achieve economic growth and therefore remain poor and underdeveloped. He goes on to list government failures as one of the reasons for failed economic growth in poor countries, and explains this by stating that governments must pro tect businesses and make it easy for people to do businesses (Sachs 59). This, he says, can be done by taking steps to assure people that it is perfectly safe and conducive to do businesses in a particular country (Sachs 60). My understanding of this is that law is heavily involved since policies have to be enacted and implemented in order for investors to inject their money into a particular economy. As a consequence, I can conclude that Sachs also agrees that law plays a vital role in economic development and should therefore be taken seriously because it is a tool for promoting and enhancing economic development. In his book the Bottom Billion: Why the Poorest Countries are Failing and what can be done about it, Collier (65) argues that â€Å"governance and bad policies help to shape economic performance, but that there is a proportionality in the effects of getting them right or wrong†. Collier is simply saying that bad governance and failure to enact the right economic p olicies can seriously dent a country’s hopes of developing. When governments cannot develop and implement policies that ensure a good environment for doing business, investors will stay away and the country will not be able to attract foreign direct investment (FDI). FDI plays a crucial role in the development of a country, and it is common knowledge that all developed nations attract a lot of FDI, and also go to great lengths to ensure that their countries are investor-friendly. In poor and underdeveloped countries, bad governance and lack of democracy leads to things dictatorships, chaos and instability. These are some of the arch-enemies of development; they greatly inhibit the ability of a country to attract investment, aid and good diplomatic relations and therefore limit its potential for development. In Easterly’s The White Man’s Burden: Why the West’s Efforts to aid the rest have done so much ill and so little good (Easterly 5), Easterly identifie s two groups that have influential roles to play when it comes to aid and the distribution of aid. He names these groups as planners and searchers, and says that planners are those who insist on a continuation of giving out aid and grants that often do not reach their intended targets, while searchers advocate

Personal statement for medical residency Essay Example for Free

Personal statement for medical residency Essay Family residency has been my passion for a long time. This is not farfetched. I have been nursing an ambition to be a family physician for a very long time, this is unconnected with a series of experiences that I have had in the past. A few days before commencing my medical training in Poland, my mother had a major heart attack and she had to be admitted for emergency surgery heart bypass surgery. The way she was attended to by the medical personnel, especially the resident physician endeared me to this particular specialty. Moreover, my experience in the medical school was a pleasant one as I learnt to deal with real life situations as they occur. i enjoyed rotating through all the units. However, the one rotation that i still cherished most was that on Family Medicine. Working with the consultants also had a lasting impression on me as I also learnt how to interact with diverse groups of individuals, from the infants to the aged. This experience was one that i would always remember because of the potential inner satisfaction that I could derive from being a Family Physician. I foresaw a future where I would be able to forge long term relationships with people with the aim of improving their health and contributing to their healthy lifestyle. This dream will be achieved if I am accepted for this residency program. I have been opportune to traverse many countries in Europe including Poland, where had my medical education. I have seen people suffer from lack of adequate medical attention. I had some clinical rotations in Chicago in a medically underserved area. This made me see people that would otherwise not have suffered had it been that they have adequate medical attention. My teachers have been my role model all the while, tutoring me for the challenges ahead. I want to be able to affect the lives of people positively in way of being their physician. I have a strong passion for this specialty. I strongly believe that this residency program will further improve my skills at becoming the physician I have always wanted to be. The total health of the patient is my concern – not only their medical health but also their emotional well being. I want to be an excellent family Physician.

Invertebrates In Soil Ecosystem Analysis

Invertebrates In Soil Ecosystem Analysis Invertebrates are the first animal evolved about 600 million years ago from single-celled microorganism, food eating microorganism. They evolved into countless forms and lead to the enormous diversity of invertebrates species that are found today. They are organism without backbone, however they have others way to produce structural support of bodies. As examples, leeches have a hydrostatic skeleton supported by sheets of muscles and internal cavity filled with fluid, while insects have a hard outer shell or exoskeleton. Scientist divided them into about 30 different groups (phyla). The phyla include echinoderms (urchins and stars), coelenterates (jellies and anemones), annelids (segmented worms), mollusks (snails and octopuses), and arthropods (insects, spiders, arachnida such as spiders and crustaceans such as crabs) (Saint Louis Zoo, 2011). There are several kinds of phyla can be referred in Figure 1. Some of them are aquatic animal and terrestrial animal, yet this paper will focu s on diversity of invertebrates in soil ecosystem only. They participate in tropic level and play vital role in nutrient cycling and decomposition of organic matter. They also interact with others organism and provide many services to the ecosystem. A small decrease in an invertebrate biodiversity may affect ecosystem as they contribute to the succession of above ground and ecosystem. Human activities which give negative effects to the soil invertebrate activities must be controlled. In meanwhile, there are also some practices can be implemented to the site/soil to eager their activities. Classification of Invertebrates An experiment was carried out by several groups of Nottingham students to study the diversity of invertebrates using soil palm sample. The table below indicates the result of my group. There are 9 kinds of animal invertebrates that have been found in the soil sample: The Invertebrates Found In Soil Palm Sample Based on the result, all the invertebrates are from phylum of arthropod. The invertebrates are diverse and made up from difference classes and orders. There are 3 kinds of classes which are Insecta, Arachnida and Myriapoda. Class Insecta give the largest percentage (64%), followed by class Myripoda (20%) and the lowest percentage is class Arachnida (16%). None of them comes from the similar order. There are only few organisms were found out. The total number soil invertebrates are 25. This happened because of several unknown factors such as less moisture. The soil sample looks like dry and non-sticky, therefore may proved that the moisture level is low and not really favor the soil invertebrates. However, more experiments should be done to determine the real factors the number of invertebrates are little. Next, the researchers have classified the diversity of invertebrates according to body width. There are microfauna, mesofauna and macrofauna. Microfauna such as nematodes usually live in water film and have width 0.1mm and below; mesofauna such as mites and springtails live in air spaces and have body width between 0.1mm to 2mm, while macrofauna such as earwigs, centipedes, and millipedes have width from 2mm to 60mm and above. Macrofauna are large enough and have ability create space by burrowing. (http://cwmi.css.cornell.edu, 2011). They exist at any stages of soil which contain appropriate space and nutrients such as in litter, on/between the surface of soil aggregates, on humus and around roots. Invertebrates that graze on bacteria such as mites always concentrate around roots while the litter is always inhibited by collembola and millipedes that break up the litter into smaller chunks (Ingham, 2011). The types of invertebrates are similar in all ground cover types, but the number s of invertebrates differs significantly. Bare soil show the lowest number of invertebrates due to it is easily exposed to the extreme temperature, drain drop and soil erosion (Kyle and Susan, 2007). Soil invertebrates inhabit a substrate that is more resistant to drought than most terrestrial habitat. Some of them are capable adapted to acidic, however many more organisms thrive in a neutral habitat causing an increase in diversity as pH approaches neutral (Rudd, 2009). Soil invertebrates present at several trophic levels of the soil food web as primary, secondary or tertiary consumers. They eat almost everything either live or death organism. They exist in multitude of ways in gaining nutrient. They may present as herbivores, carnivores, scavengers and parasites. As examples, herbivores like caterpillar and nematodes are feeds on plants. Nevertheless, nematodes are complex organisms which appear at several stages of tropic level. Some nematodes feed on the plants and algae (primary consumers); others are grazers that feed on bacteria and fungi (secondary consumers); and some feed on other nematodes (tertiary consumers) (Ingham, 2011). Next, carnivore can be represented by centipedes which feed earthworms by paralyzing their prey with poisoned fang and spider which traps their prey with web. The example of scavengers is millipedes, louse and earwigs which decompose plant matter such as leaf little and dead roots (Dr Alderson, 2011). Most of inverteb rates in soil are parasites. Ticks, tapeworms, leeches, mites and roundworms are just a few examples of the parasites. Some parasites live on the external surfaces of the hosts while the others live in the digestive tract or tissues of their hosts (Klappenbach, 2011). Next, soil invertebrates develop multiple interactions at large scale and contribute to the production of soil ecosystem services in many ways (Figure 3). The Advantages of Invertebrates Interact with Ecosystem Firstly, soil invertebrates participate in nutrient cycling as it interact with surface vegetation which supplies them the organic maters or compounds. Scavengers like millipedes and mites will return those elements into a broken down form. These broken forms will be recycling back into the environment, promoting humification and nourishing the plant with the nutrients like nitrogen and carbon. Soil invertebrates are responsible for the mineralization and immobilization of phosphorus and sulphur into the plants. They attribute regulation of leaching nutrients losses and prevent leakage towards low-lying aquifers, streams and oceans (Lavellea et.al, 2006). Soil invertebrates act as buffering system that allows an efficient local recycling of nutrients Next, invertebrates like ants, termites, earthworms help in formation of soil. They consume small aggregates of mineral particles and organic matter and then generate larger fecal pellets. These fecal pellets are coated with compounds from the gut and become part of soil structure. Charles Darwin has stated that soil invertebrates, earthworm can carry large quantity of soil from the lower strata to the surface and organic matter into deeper soil layers. This organism can form over the top 15 cm of soil within 10-20 years. It helps to hold the soil particle together and maintain it structures too (Clive, 2011). Invertebrates interact with plants as they support primary production such as genes and protection against pests and diseases for plant health and response to stress. The expert document that the expression in the leaves of three stress-responsive genes (coding for lipoxygenase, phospholipase D and cysteine protease) due to the existence of belowground invertebrate activities. However, they still cannot identity the mechanism involved which affects parasitic nematodes activity and arise beneficial in earthworms. Next, many experiments have shown significant enhancement of plant production in the presence of soil invertebrates such as collembolan, earthworms and combinations of organism termites and ants. Invertebrates capable improve tolerance to stressors or pest such as parasitic nematodes which feed on plant roots. This has been proved since 82% infested plant decrease within the presence of earthworms. Although earthworms do not affect the population size of nematodes, it causes the root biomass not being attacked by such parasite (Manuel et al, 2005). Besides, the soil invertebrates interact with carbon compound in climate regulation and also with soil for flood and erosion control. The soil invertebrates accumulate over long period of time and form humification. This process results the carbon compounds are sequestered into compact and consequently the carbons can be avoided from rapidly released into atmosphere in the form green house gases. Humification also transforms carbon compounds more resistance to further decomposition and thus slower green house gas released from soil (Lavellea et.al, 2006). Next, flood and erosion control can be regulated by building and maintenance of stable porosity through bioturbation and burrowing. Earthworms burrow, enhance soil aeration and form tunnel. This tunnel can absorb water at a rate 4 to 10 times greater than fields lacking worm (NCAT, 2004). Lastly, soil invertebrates do interaction with ecosystem as they are also responsible in production of water supply. Their participation may be in small-scale but are significant. Invertebrates such as millipedes in macrofauna create burrows and structural porosity in soils and thus generate water infiltrations. The variety of pore shapes and size may permit soils to store water within wide range, but the scientist not discovered yet about the amount of water infiltrated and stored (Lavellea et.al, 2006). Invertebrates are necessary to reduce water runoff, recharge groundwater and store large amount of water for dry spells. Soil invertebrates serve many benefits to plant, animal, and nature. Their present should not be disturbed by human activities because it may influence the presence and activity of organism. Unfortunately, the burgeoning human populations have destroyed the soil physico-chemical environment and the soils species through activities such as: inputs of chemicals, disposal of waste products in soils and physical modification or removal of soil by cultivation and erosion (Diana, 1994). Those activities may eliminate any invertebrates present on the topsoil and degrade their microenvironment. In addition, the metabolism of microorganisms and arthropods will be altered and this may destroy some layers of the primary food chain too. This happens when harmful chemicals have been passed up to the food chain and ultimately causes mortality or even extinction in the invertebrates. There are several site/soil management can be practiced to help improving invertebrates number and activities such as enhance nutrient and pest. Organic matter and nutrients in acceptable range can provide more foods to the invertebrates, though they may poison the organism in excess. This is similar to pest which is helpful for invertebrates to resist to pesticide in acceptable range only. Next, people must avoid excess tillage because it can bring advantages or conversely. Some farmers practice tillage because it can control pests, however it also affects decomposition rate of soil invertebrate when excess. The worst is it can reduce organic matter level to below 1% and renders them biologically dead. People also should keep the soil covered to avoid soil erosion that influence the existence of invertebrates at the topsoil especially. It can be done by covered it with plant residue or planting crops. Lastly, diversity cropping is beneficial because it also will increase the diversi ty of invertebrates. This happen due to differ plant have differ culture practice and thus leads to decrease of disease pressure. All the practices support the invertebrates to survive greater and functions more effectively (USDA, 2011). In conclusion, there are vast diversity of invertebrates can be found in earth including soil invertebrates. Their size are small which is may be less than 1mm but their interaction with nature bring much benefits to ecosystem. Their existence should not be bothered and people must conserve these species to avoid extinction via soil conservation. Soil conservation can promote better the viability and survivor of soil organisms including soil invertebrates. Loss of invertebrates diversity may affects soil processes and unstable ecosystem too as they are responsible in nutrient cycling, water supply and many more. People can manage the site/soil to improve the population of invertebrates by providing nutrients, pest and others to enhance invertebrates activities.

Huckleberry Finn, Daisy Miller and Sister Carrie as Heroes Essay

The definition of a hero is not straight-edged. Heroes are, however, imagined to possess certain qualities. Courage, romanticism, charming beauty, and a willingness to defy society are four very prominent characteristics amongst heroes and contribute to today's notion of heroism. In order to decide if and to what extent any character lives up to the standards of heroism, one must search for these qualities. Huckleberry Finn, Daisy Miller, and Sister Carrie are three heroes from three different novels. It has already been decided that they are heroes. Therefore, the question is not whether or not they are heroes. The question is to what extent do they fit this notion of heroism? To what extent do they possess courage, romanticism, noncompliance, and beauty? As their characters? are searched and examined, one will discover that each may be a little brave, romantic, rebellious, and attractive, but they all fall short of the complete hero. Huckleberry Finn is brave, but he lacks romanticism and beauty and caves into society?s pressure. Daisy Miller stands firm when society tells her to change, but she lacks real courage, romanticism, and beauty. Lastly, Sister Carrie is beautiful and romantic, but she is neither courageous nor willing to resist society?s influences. The three characters ? Huck, Daisy, and Carrie ? overcome some obstacles and attain heroic qualities, while other obs tacles hinder them. Huckleberry Finn, hero of Mark Twain?s Adventures of Huckleberry Finn, possesses courage, one of the four main pillars of a heroic building. However, his building does not stand tall because he lacks the other three pillars. His foundation is not sturdy. He, like all of the characters, falls short of the heroic ... ...use he is a victim to his environment. On one page he is Huck and on the next he is ?Tom Sawyer.? And then there is Carrie, the imitator. Her final profession as an actress perfectly fits her character. Daisy is the only one who stays true to her character. She may just be a daisy, but she is a dependable daisy. Her character is consistent, and, therefore, one can trust that the heroic qualities she does possess will persevere in any conditions, even if unwavering means death. Works Cited Dreiser, Theodore.

Signal Conditioning Characteristics Engineering Essay

This study presents the design, execution of a room temperature lumberman which measures temperature, and logs in informations utilizing a clip specified by the user in seconds. It besides shows the consequence and analysis of noise nowadays in the system. The temperature is sensed utilizing a type K thermocouple whose end product is fed through an AD595 signal conditioner which performs cold junction compensation, linearization and elaboration. A hardware filter is so created to filtrate the signal coming out from the AD595 signal conditioner. A data acquisition card is provided which takes the end product of the signal and converts it from parallel into digital signifier and presents the informations to the computing machine system running LabView Virtual Instrumentation package. The LabVIEW Virtual Instrumentation plan so digitise electromotive force by executing noise analysis utilizing power spectral denseness, and change over the electromotive force signals into temperature. Th e LabView VI besides provides a block diagram where the instruments are placed, and a forepart panel which provides graphical and numerical temperature show to the user and shops the temperature over clip in a file on the computing machine. High and Low temperature set points are provided with an dismay system to supply audiovisual warnings accompanied with a honking sound to the user if temperature deviates from the set points. The most popular transducer for mensurating temperature is the thermocouple. It is one of the simplest of all detectors ; it is an cheap, rugged device that can run over a really broad scope of temperatures. The thermocouple besides has alone signal conditioning demands. Thermocouples operate on the rule that the junction of two dissimilar metals generates a electromotive force that varies with temperature. The end product is a little electromotive force measured between the two wires ( National Instruments, 2010 ) Figure1: Thermocouple ( culled from www.capgo.com/Resources/Temperature/Thermocouple/thermocouple.html ) The thermocouple Acts of the Apostless as a temperature detector and it produces a comparatively little end product electromotive force. To show a more feasible consequence from electromotive force, signal conditioning is required by either linearizing or amplifying. The thermocouple used is a type K which consists of chromel and alumel. In order to input the information from the thermocouple into a computing machine, vitual instrumentality is used to treat the signal by utilizing suited package which generates studies and consequences. The thermocouple ( which is a transducer ) converts temperature to voltage and a information acquisition board is so used to change over the parallel signals into digital signals which are so fed to the computing machine. The DAQ acquisition package ( Labview VI ) converts the digital signals into graphical indexs utilizing the front panel and block diagrams. Display charts are so placed to reexamine the signal acquired.1.1 AIMThe purpose of this study is to bring forth a Labview VI to get temperature informations from the thermocouple ( Type K ) , runing from 20A °C – 50A °C ; supplying valid instantaneous numerical informations, an dismay option ( Tmax – Tmin ) , a graphical end product and a file storage option. The study presents a brief theory subdivision, the following subdivision discusses the experimental apparatus ( with the package filter and hardware filter ) , processs and design considerations, so the consequences are produced, and so the decision.2. Theory2.1 ThermocoupleA thermocouple is a type of temperature detector, with its circuit holding at least two junctions ; the measuring junction and a mention junction. The mention junction is created where the two wires connect to the measurement device. The measurement junction is the terminals of the two wires, but because they are assumed to be at the same temperature ( isothermal ) they are considered as one ( thermal ) junction. The end product electromotive force is related to the temperature difference between the measuring and the mention junctions. This is known as the Seebeck consequence. The Seebeck consequence generates a little electromotive force along the length of a wire, and is greatest where the temperature gradient is greatest ( Capgo, 2010 ) .2.2 SIGNAL CONDITIONING & A ; CHARACTERISTICSDetector Electrical CHARACTERISTICS SIGNAL CONDITIONING REQUIREMENT Thermocouple Low-tension end product. Low sensitiveness. Nonlinear end product. Reference temperature detector ( for cold-junction compensation ) . High elaboration Linearization. Table 1: Electrical Features and Basic Signal Conditioning Requirements ( culled from hypertext transfer protocol: //zone.ni.com/devzone/cda/tut/p/id/4084 # toc2 ) . The thermocouple has its assorted features and ensuing signal conditioning demands ( as shown above ) . The choice of a peculiar solution nevertheless depends on the size of one ‘s pocket, development velocity, elaboration factor and linearization. A simple solution is by utilizing an IC bit ( such as the AD595 ) which provides signal conditioning, cold junction compensation, high electromotive force addition ( elaboration ) and compensates for non one-dimensionality of the thermocouple signal. It has been preconfigured to supply a electromotive force end product relative to temperature ( 10mV/A °C ) straight from type J/K thermocouple signals. The device is packaged in a 14 pin DIL IC bit. It operates utilizing a broad supply electromotive force scope +5 to 30V.2.2 DATA ACQUISITION ( DAQ )Data acquisition involves garnering signals from measuring beginnings and digitising the signals for storage, analysis, and presentation on a Personal computer. The intent of informations a cquisition is to mensurate an electrical or physical phenomenon such as electromotive force, current temperature, force per unit area, or sound. The PC-based informations acquisition system is defined by its application demands by geting, analyzing and showing information. Data acquisition systems integrated signals, detectors, actuators, signal conditioning, informations acquisition devices and applications package. Figure 2: PC-based Data Acquisition ( culled from hypertext transfer protocol: //www.ni.com/dataacquisition/whatis.htm )3. EXPERIMENTAL SET-UP AND PROCEDURE3.1 EXPERIMENT ( WITH HARDWARE FILTER )Figure 3: Block diagram for Experiment with hardware filter.3.1.1 HARDWARE FILTER SELECTIONBecause the signal passing through the system is low ( i.e. 10mv/A °C ) a lowpass filter is used to observe the signal passing through. Due to the creative activity of the filter ( hardware ) a cut-off frequence has to be set in order to find the value for the capacitance and the resistance to be used, i.e. utilizing a RC filter. Figure 4: RC filter. To find the resistance and capacitance to be used the expression for a RC filter is used, such that ; Where C = electrical capacity, which was given at 0.1A µF, R= Resistance, and = Cut-off Frequency. The cut-off frequence is defined as the frequence below which the addition drops 3dB ( National Instruments, 2009 ) . A cut-off frequence of 4Hz was chosen. Therefore at a cut-off frequence of 4Hz, and a electrical capacity of 0.1A µf, we have the opposition at ; R = 397.89Ka„ ¦ .3.1.1 CIRCUIT CONNECTIONFor the circuit connexion, a type K thermocouple and a pre-calibrated signal conditioner AD595 were supplied. The circuit for thermocouple conditioning was built utilizing a veroboard. Figure 5: Thermocouple Signal Conditioning Circuit with a beltway for the hardware filter ( Culled from Analogue Devices Monolithic Thermocouple Amplifiers with Cold Junction Compensation AD594/AD595 Datasheet ) . A hardware filter is connected to the end product of the AD595 at pin 8, such that the signal is been filtered before come ining into the DAQ. The positive terminus of the end product is connected to the linear channel on the DAQ, which provides the filtered signal. Besides, at pin 8 the junction of the AD595 and the hardware filter, signal is tapped out, which is connected to another parallel channel on the DAQ, which provides the unfiltered signal. The common or signal land is connected to the linear channel land. Besides, pin 11 with an end product of +5V was connected to the DAQ, to feed a electromotive force beginning to the system. The connexion manner used is the referenced individual ended ( RSE ) because the full negative terminuss are common ( i.e. grounded ) . Double ended input harmonizing to informations sheet of the thermocouple signal conditioning unit ensures really low degree of noise. The end product provided readings for when the signals are filtered and unfiltered .3.1.2 DAQ CONFIGURATIONThe matching of input electromotive force scope to end product electromotive force scope of transducer is required to take advantage of the DAQ ‘s declaration. From the AD595, the end product electromotive force per temperature is 10m/A °C, hence, the end product electromotive force scope of the transducer at Tmin = 0A °C is 0V and at Tmax = 50A °C is 500m. A scene of Vmin = 0 and Vmax = 1V will be sufficient because the input electromotive force rang to the DAQ is non expected to swing above 1V. Figure 6: DAQ Configuration3.2 VI ProgramA practical instrument plan is made up both the front panel and the block diagram. The front panel acts as the user interface to the measuring systems and it contains controls and indexs. A VI was created to analyze and expose temperature signal. Graphic indexs are required to see and analyze the information. The figure below shows the VI for analysis. Figure 7: Block diagram of signal analysis and thermometer measuring Figure 8: Block diagram of informations file and temperature lumberman. Figure 9: Front panel demoing the signal wave form, and temperature reading From Figure 7, since there is an in reinforced filter ( the hardware filter ) , the end product signal from the DAQ is split into two parts incorporating a filtered signal, and an unfiltered signal ( which was tapped out ) . Both signal are connected to the spectral measuring which analysis the input signal and provides a PSD ( Power Spectral Density ) , which plots the Power against frequence, and it ‘s suited for analysing the noise in the signal. In order to obtain the temperature readings from the thermocouple, a thermometer is placed such that readings from the end product signal ( sing the filtered signal ) is assumed to be multiplied by 100 ( as shown in the informations sheet ) to give an accurate reading in temperature ( A °C ) . String sections are set such that a show is shown at the front panel when the temperature is above or below a temperature scope set ( say 30A °C – 50A °C ) . Figure 8 shows how the information is being salvage and how the lumberman is set. The signal inputs passes through the mean, which sends selected signals into the write measuring file, and harmonizing to the scene of the lumberman ( in seconds ) , the readings are being stored. Figure 9 shows the front panel of the VI, here it is seeable to see the result of the temperature reading, and controls are set in order to alter the system harmonizing to the user ‘s desire. A thermometer is set to demo the temperature reading when increasing or decreasing, an dismay is placed such that if readings are above or below a set status, a warning is set so that the dismay index water chickweeds and a beeping sound is heard. The following below show constellations of some of the diagrams discussed above ; Figure 10: Configure Spectral Measurements Figure 11: Configure to Write to Measurement File4.

Figure 14: PSD of filtered ( ruddy ) and unfiltered ( black ) signals at 1000 sample per rhythm and at a frequence of 500Hz. A signal is composed of two parts, the wanted signal and noise ( Pugh et al, 2010 ) . We consider the filtered signals from the figure above. Noise occurs when there is a deformation of flow in the signal ; such can be seen in the unfiltered signal where presence of noise is more seeable. In order to take most of the noise a low base on balls filter was used, with a cut-off frequence of 4Hz. The consequence of this showed minimum presence of noise in the system with really few deformations. It should be noted a possible beginning of noise in the system can happen from the brinies ( 50Hz and its multiples ) . From the figures above, at frequence 1 KHz, and samples of 1K, we observe white noise being present from 15Hz, with spikes at 45, 105, 205 and 265Hz. Besides at the frequence 500Hz, and samples of 1K, we observe white noise being present from 15Hz, with spikes at 50, 125, 165, 200, 285 and 365Hz. It is of import to cognize that the white noise is the most dominant noise, and it starts at the beginning of the spectrum.5. 100 CHANNEL SystemIn order to make a 100 channel logging system, the most suited equipment to utilize is a PXI-2575 or SCXI-1175. The National Instruments PXI-2575 and SCXI-1175 are high-density 100 – channel all-purpose multiplexer switch faculties. With 198 1-wire channels or 98 2-wire channels, the NI PXI-2575 and NI SCXI-1175 are capable of routing 100s of signals to measurement devices or from beginning units. Each channel uses robust electromechanical relays and is capable of exchanging up to 100 VDC/100 VAC or 1 A. With a scanning velocity of up to 140 hertzs, these faculties act as an first-class front-end for high-channel-count machine-controlled trial applications. Expanding the multiplexer channel count of an SCXI system is every bit easy as adding extra faculties. Analog signals can be passed between two or more SCXI-1175 switch faculties via the high electromotive force parallel backplane ( HVAB ) in an SCXI human body. Include the HVAB arrangers for a 4-slot SCXI human body ( p/n 776575-57x ) or a 12-slot human body ( 776575-58x ) to put up this capableness. With these connexions, you can immediately spread out your channels without complicated wiring ( National Instruments, 2010 ) The cost of this system is set at ?1,549, which is just monetary value given its versatility and easy use. Should be recommended for a company/University usage instead than self intents ( unless affordable ) . Figure 15: The National Instruments PXI-2575 ( left ) and SCXI-1175 ( right )6. DecisionThe overall purpose of the experiment was accomplished as temperature was acquired at a rate of 0.001 Seconds, with a hardware filter inputted in it, holding a cut-off frequence at 4Hz, electrical capacity of 0.1A µF and a opposition of 397.89 to take accompany noise signals, averaged over a scope between 100 – 1000 samples and so logged every 3 seconds. The dismay system displays a â€Å" Low Temp † message when temperature dropped below 20 grades and a â€Å" High Temp † message when it rose above 30 grades centigrade and makes a beeping sound. Noise was reduced with the aid of a Low base on balls filter and farther, by averaging over a figure of samples.

In order for one to be truly omnipotent there of course must be no limits on ones power. Any constriants what so ever render omnipotence a meaningless term. To say that an omnipotent beings power is in accordance with or follows a guideline law or any similar requirment is to limit the power of that being . To say that an omnipotent being acts in accordance with a law, is to imply that said being could not act without said law or that there would be some penalty or harm if the being were to do so. If onmipotnece is to be true it is not to be guided, circumscribed filtered etc.; these are limits in one way or another on power. To call a being good is to make a judgement about its character. Character judgements are derived from actions. To say that a being is good is to say that it demonstrates good behavior, that it’s actions are good actions. Besides actions one may also judge intent when judging character. Ones actions must not only be good they must be done with the intent the purpose of being good. Good actions are derived from the willing of reasoned good intent. This being said actions and intent are seperate things and so can be judged independanlty of each other. Intent and reasoning precedes action.In order to judge a thing good one must have something that is in some way sepreate or outside of the thing being judged to judge the thing being judged. If you use the thing being judeged as the standard by which to judge it then you have really made no judgement at all. You have merely created a relationship of identity; judgement of the thing= the thing itself. When this relationship of ide ntity between a being and good is established the definition of good depends solely on the being itself. Since the being is good anything it does is good. This makes the definition of good arbitrary. With this all and every possible action by a being defined as good is good this is not at all a way in which good is used in any other situ...
