Runners on first and second squinted from the glare as they watched the pitcher's mound for the opportunity to run. Advise for the runners as well as the batter was screamed and from the stands of spectators. Adding to the din of noise was the chant of the infield and outfield, ?Hey, batter, batter!? The smell of popcorn and barbeque permeated the air. Water bottles emptied as players sought to stay hydrated from the suffocating source of heat that surrounded them. The ball field was alive with action! The midnight moon lazily lit the ball field. The red infield clay reflected a rusty tone lightening ever so slightly at the pitcher's mound. The moon light on bases lit up their lonely abandoned positions. Dew on the grass of the outfield announced the outer limits of the game area. Silver spectatorsstands invited the moon light to bathe them. All was still, stationary, secluded. The night blooming jasmine mixed with the salty sea breeze and perfumed the air. Still all was so spectacularly serene. Yet, pause, listen carefully, this is the place where hopes and dreams can be heard. Bibliography none

American Industrialization from Civil War to WWI Essay Essays

American Industrialization from Civil War to WWI Essay Essays American Industrialization from Civil War to WWI Essay Essay American Industrialization from Civil War to WWI Essay Essay Between the Civil War and the terminal of World War I. industrialisation played an of all time increasing function in the economic. societal. and political development of the United States. Industrialization had a immense impact on American in all of these ways. such as many Americans traveling from the rural countries to urban countries. populating the large metropolis life style with Industrialization on the rise. Social Darwinism besides known as Survival of the fittest took an impact during this clip period. the state was confronting great alterations doing many people to get down new life styles. Peoples began working in mills and large edifices alternatively of on farms. Labor brotherhoods besides were formed to protect the workers from unjust rewards. long yearss. insecure conditions. etc. Although there were positive effects during this clip there were besides negative effects on the societal. political. and economic. facets of the United States. First I will travel over how industrialisation affected America economically. Industrialization was at a rise during this clip many â€Å"Big Shot† industrialists became rather affluent from this. although most industrialists used ruthless concern tactics to roll up their wealth. Andrew Carnegie believed in the moral responsibility of the rich giving back to the community so he spent much of his wealth paying for libraries. universities. trust financess. and Carnegie Hall to be built besides making more occupations ( Shown in Document 8 ) . Another Economic consequence on the United States was the American entry into WWI. The ground forces for the United States wasn’t as prepared for the modern candidacy military action like other European states. America’s productive strength made up for that by hiking one million millions of dollars and our industrial potency caused its portion of universe fabrication end product to be 2 and a half times that of Germanys. Our entry transformed the balances and compensated for the prostration of Russia at the clip ( Shown in Document 9 ) this being a positive of American industrialisation. Following I will discourse the societal impact industrialisation on the United States. Due to such the high demand for employees and work at the clip working conditions weren’t ever so great. Clara Lemlich a labour brotherhood work stoppage leader sparked the 1909 walkout of shirtwaist shapers. The work stoppage occurred because workers were doing approximately $ 6 a hebdomad on a good hebdomad. are invariably at their machines from 7am to 8pm daily with merely one 30 minute tiffin interruption. This work stoppage gathered the public’s attending fueling the creative activity of labour brotherhoods and labour Torahs ( Shown in papers 6A ) . Due to hapless on the job conditions. insecure and unhealthy work environments. and kids working started the creative activity of labour Torahs. One of the first of these was the Laws of the province of Illinois and their transition of the 38th general assembly. Some of these Torahs were if upon review such workshops shall be found unhealthy/infectious orders will be given and actions taken as the public wellness shall necessitate. Another jurisprudence passed was kids under 14 are prohibited from being employed ; besides no female shall be employed in any mill or workshop for more than 8 hours a twenty-four hours or 48 hours a hebdomad ( Shown in papers 4 ) . Industrialization from the Civil War to World War I affected the societal facet of the U. S. by drastic alterations. changes the American people were non used to this is where Social Darwinism comes into drama. Following I will cover the political alterations industrialisation caused during this clip period. The â€Å"Captains † of Industrialization during this clip were chesty. such as Mr. Rockefeller they believed they were above the Government and politicians. This created Bad Trusts that reduced competition and drove up monetary values. Theodore Roosevelt the president at the clip became a trust fellow. by making the Sherman’s Antitrust Act in 1890 this declaring all combinations of in restraint trade now illegal ( Shown in papers 7B ) . Another illustration of the political impact was the Boss tweed and Tammany Hall dirt. Tammany hall was a political organisation formed in 1786. and played a major function in commanding New York City and New York State political relations. Boss Tweed was an American politician and the â€Å"boss† of Tammany Hall. Boss tweeds control over the political backing in NYC through Tammany Hall every bit good as the tenseness between political leaders an industrialisation â€Å"kings† lead to Boss tweed holding and unjust add vantage over other campaigners. guaranting trueness of electors through occupation offerings. The result of this later resulted in Tweed’s strong belief for stealing an estimated $ 25- $ 45 million dollars from NYC revenue enhancement remun erators due to political corruptness. In decision the epoch between the Civil War and World War I’s industrialisation played an of all time increasing function in the economic. societal. and political facet of the United States in both negative and positive facets. Economic alterations ranged from where the people chiefly lived and types of occupations to how they changed. Equally good as labour brotherhoods and labour Torahs altering working conditions. to the American entry into WWI. Social alterations ranged from the epoch of reform. the women’s rights motion and the 19th amendment and their right to vote. every bit good as adult females doing mass meetings and work stoppages. Last the political alterations ranged from Theodore’s Roosevelt’s â€Å"Trust Busting† to political greed and corruptness.

Does the internet create more distribution problems than it solves Essay

Does the internet create more distribution problems than it solves Critically evaluate with reference to channel conflicts. include relevant examples and theories in your appraisal - Essay Example Bovet and Martha (2000) explained this in their value net, wherein the distribution centre provides bought products on a just-in-time basis. (p58) What this means is that the Internet significantly reduced the cost of distribution, while making the process faster and responsive to the needs and requirements of the consumers. Now, this is the ideal landscape. Several years have passed and a wealth of experience has been collected. There are some sectors who argue that the Internet has created new distribution challenges, which are dominated by the emergence of channel conflicts. This paper will explore this theme. Particularly, the investigation will focus on the tourism industry. For some, the Internet is considered one of the greatest developments in the history of mankind, if not ever. (Katz and Rice, 2002, p2) This claim may have some ring of truth to it since the technology has almost single-handedly reduced the world into a global village, effectively eroding the effect of time difference, geographical location and national borders in the way people interact and consume goods. The platform became popular because it allowed easy and inexpensive communication of one to one, one to many, many to one, and many to many – an achievement that is unparalleled in history. (Sullivan, 2002, p177) It has helped globalization to achieve its purposes and, in turn, is encouraged by that economic phenomenon in a mutually reinforcing relationship. This is the basis of the emergence of the so-called e-commerce concept, a new model that significantly challenged the traditional bricks and mortar model. Through the internet technology, people can sell products and se rvices over the internet network without having to worry about store space and intermediaries. According to Gay, Charlesworth and Esen (2007), the technology allowed the linking of front and back

Greenhouse gas emissions Assignment Example | Topics and Well Written Essays - 250 words

Greenhouse gas emissions - Assignment Example Fluorinated gases in combination with chlorinated gases form chloro-fluoro carbon or CFC which are the major factors responsible for deteriorating the quality of Earths atmosphere. They are responsible for the depletion of Ozone layer, paving the way for harmful uv radiation in the planet. Green house gases take up and give off radiations in the thermal infrared range and hence lay the foundation for green house effect, a rise in temperature. Therefore, Green house gases greatly affect the temperature of the earth, causing an exponential rise in the planets temperature. This has resulted in alteration in surface climate, precipitation, famine and surface hydrology, transformation in the open environment, modifications in tropics, subtropics and in the monsoons, conversions in atmospheric conditions, climatic variations and melting of glaciers causing elevation of the sea level. The temperature of the planet is severely affected by these green house gases and the situation has become alarming. In view of this various countries have joined hands to reduce the use of those commodities which are responsible for the emission of GHGs. It is still only the beginning and we have a long way to march down to prevent the further deterioration of the

Adaptive Energy Efficient Transmission in WSNs

Adaptive Energy Efficient Transmission in WSNs A novel approach for adaptive energy efficient transmission in WSNs S Murthy Vedireswarapu, Muni Bhaskar. Athikayala Shankar.T Abstract In wireless sensor networks (WSNs), sensor nodes work on finite capacity batteries. So, in order to increase network lifetime the mobile sensor nodes should be operated at low power. Hence, we need a novel approach for efficient scheme for transmission in WSNs. In this scheme, according to temperature changes the connectivity between sensor nodes is estimated by using open loop process, the network is divided into three regions based on closed loop feedback process which helps to reduce packets overhead in the network. Region dependent threshold on loss of transmitter power (RSloss) and present number of nodes in each region helps to adjust transmission power level according to changes in connectivity between nodes because of changes in temperature. This scheme achieves high energy saving than existing conventional method. Index Terms—threshold on transmitter power loss, wireless sensor networks (WSNs), transmitter power level. I. INTRODUCTION Wireless sensor networks (WSNs) works based on IEEE 802.15.4 standard. This standard operates at frequency of 2.4GHZ and data rate of 250 kbps. WSNs are used mainly in industrial, bio medical, security surveillance and weather monitoring applications. Each sensor node consists of: radio transmitter, receiver, sensing unit, processing unit and limited capacity battery [1] .Because of limited battery lifetime at each sensor node, the transmitter power level should be minimized to increase the energy efficiency and network lifetime of WSNs. In WSNs all the systems should be operate at low power to increase energy efficiency because it is an important concern in wireless communication. To collect data from different environments sensor nodes are deployed at different locations within WSNs. While the communication between sensor nodes they consume less power as sensor nodes operate on limited battery, and temperature effects the connectivity between the sensor nodes. So, we need to reduce energy consumption for communication between sensor nodes, and at the same time ensure that good connectivity between sensor nodes in order to increase network life time [2-4].we analyzed a new scheme for Ptlevel to efficiently adjust the connectivity between nodes due to temperature changes. This scheme improves network lifetime while maintaining good connectivity between sensor nodes. By using temperature sensor, the connectivity between each node is estimated in open loop process. Estimated degradation in connectivity is compensated by using closed loop feedback process in the new scheme. In this scheme we obtain less transmission power compared to existing schemes. II. LITERATURE REVIEW In algorithm of local mean (LMA), Based on number of received acknowledgements by the reference node the transmission Plevel is adjusted according to threshold transmission Ptlevel .It improves network lifetime but cannot estimate the link quality [5]. In other existing schemes based on RSloss, transmitter Ptlevel is estimated [6]. In other existing scheme closed loop feedback process is used for connectivity estimation .In this scheme each node aware of required Ptlevel to be maintained with its adjacent nodes. According to connectivity changes it adjusts the transmission power level [7].The above schemes cannot guarantee both low power transmission and good connectivity between nodes. The new scheme efficiently adjusts the connectivity changes according to temperature changes. Based on RSloss ,Ptlevel is estimated for all three regions for good connectivity between the nodes. III. PROBLEM STATEMENT In WSNs due to multipath propagation signal strength varies irregularly, the signal strength mainly depends on the transmitted power at any time. The reason for the variation in the RSloss .First the variation in signal strength according to distance due to multipath effect, secondly the environmental factors like temperature effects the signal strength. So the temperature is one of the main factors which affect the RSloss and transmission power level. Hence we need to compensate these parameters according to surrounding temperature variations. IV. SOLVING METHODOLOGY In this scheme open loop feedback process uses temperature sensor to detect the temperature variations. In closed loop feedback process, transmission Ptlevel is adjusted based on control packets overhead. Based on open loop and closed loop feedback process the network is divided into three logical regions: as high, medium and low represented with X, Y and Z respectively. In this scheme we use RSloss to measure the connectivity with relatively low overhead. Open loopnc(t) nd(t) Closed loop Figure 1: Block diagram V. ENERGY-EFFICIENT TRANSMISSION SCHEME. In this scheme, transmission Ptlevel is adjusted by the power controller by utilizing the current number of nodes and temperature sensed by each node. Temperature compensation is done in case of any changes in temperature sensed at a sensor by using the relation between temperature and RSloss. Transmission power loss due to temperature variation is given as [9] RSloss[dBm]=0.1996*(T[0C]-25[0C]). By using LSA the transmitter Ptlevel is obtained as follows [9] Ptlevel=[(RSloss+40)/12]^2.91 According to free space model the actual transmitter power level is obtained as follows, Ptr[dBm]=[ ÆÅ ¾*( Eb/No)*mkTB*(4ÃŽ  d/ÃŽ »)2+RNF]+RSloss Here number of nodes (N), distance between each node (d),signal to noise ratio(Eb/No), spectral efficiency(ÆÅ ¾), frequency(f) and Receiver noise figure(RNF). [9] The main variables are transmitter power loss and transmitter power in each region decides the working of working of algorithm. A beacon message is broadcasted periodically by the reference node and waits for ACKs. If ACKs are received from nodes, RSloss is estimated for division of network logically, considering region X with high RSloss, region Y with medium RSloss and low RSloss as Z region. Estimating of transmitter Ptlevel is as follows: If RSloss loss threshold then default transmitter Ptlevel is assigned. In other case if RSloss ≠¥ RSloss threshold and nc(t) ≠¥ nd(t) ,then threshold Ptlevel is assigned. For similar case with nc(t) d(t) transmitter Ptlevel is assigned. Minimum, Maximum and Average value of RSloss for all nodes present in the network can formulated as follows: RSloss(min)=min(RSloss(k)), RSloss(max)=max(RSloss(k)), RSloss (Avg) = (min(RSloss(k)) + max(RSloss(k)))/2 Then limits of the three regions are given as: [7] For region X: RSloss( X max)=max(RSloss(k)), RSloss( X min)= (RSloss(Avg)) + 2 Figure 2: Flow chart of reference node [7] To count number of nodes in each region, a counter is initialized with initially zero. For region Y: RSloss( Y max)=(RSloss(Avg)) + 2 RSloss( Y min)=(RSloss(Avg)) – 2 For region Z: RSloss( Z max)=(RSloss(Avg)) – 2 RSloss( Z min)=min(RSloss(k)) ; k ÃŽ µ N RSloss( X Threshold) = RSloss( Y Threshold) = RSloss( Z Threshold) = RSloss ­-new(X,Y,Z)(k)=RSloss(Threshold X,Y,Z) Given that for all k Ɇº N, RSloss(Threshold X,Y,Z)≠¤ RSloss(X,Y,Z)(k) And nc(t)(X,Y,Z) ≠¥ nd(t)(X,Y,Z) RSloss-new(X,Y,Z)(k)=RSloss(X,Y,Z)(k) Given that for all k ÃŽ µ N, RSloss(Threshold X,Y,Z) ≠¤ RSloss (X,Y,Z)(k) And nc(t)(X,Y,Z) ≠¤ nd(t)(X,Y,Z) or RSloss(Threshold X,Y,Z)>RSloss(X,Y,Z)(k) Estimation of Ptlevel for new RSloss is formulated as for all k Ɇº N, Ptlevel-new(X,Y,Z)(k)= [(RSloss-new(X,Y,Z)(k)+40)/12]^2.91 The difference between Ptlevels assigned before and after the proposed scheme is denoted as Ptsave. Ptsave (X,Y,Z) = VI. SIMULATION RESULTS Figure 3: Transmitter power saved in region X for different reference node location. From figure 3, we can infer that, maximum Ptsave is 12dBm to 21dBm. When a reference node is at origin of the square region, Ptsave is constant around 1dBm. Figure 4: Transmitter Ptsave in region Y for different reference node location. From above figure, we can infer that maximum. Ptsave for region Y varies from 12dBm to 21dBm Figure 5: Transmitter Ptsave in region Z for different reference location. Figure 6: Transmitter power for different rounds. From above figure 5, we can infer that Ptsave for region Z varies from -20dBm to 20dBm. From figure 6, we can clearly observe that Pt lies between -84dBm to – 80dBm. VII. CONCLUSION By using this scheme the energy consumption of the mobile nodes is reduced in WSNs. This scheme uses both open loop control and closed loop feedback control process. The temperature changes are adjusted with the help of open loop process. By using these two processes the energy consumption of mobile sensor nodes is reduced by comparing with existing schemes. By dividing the network into three different regions we can prolong the lifetime of network and maintains good connectivity between sensor nodes.

The Human Genome Project :: Exploratory Essays Research Papers

The Human Genome Project    With technology increasing daily in our modern society, we have to wonder what will come of all of the recent studies and large-scale research projects that have involved genetics. After recently reading two articles, I have been able to formulate some of my own predictions of what’s to come. In Lisa Sowle Cahill’s article, â€Å"The genome project: more than a medical milestone† she tells us in a concise manner, the history of the Human Genome Project. â€Å"The Human Genome (H.G. P.) began in 1990 as an international consortium of scientific terms. It planned to map systematically the entire human genome by the year 2005 on a budget of $3 billion. The major supporters of the H.G. P. are the Wellcome Trust, a large medical charity in the United Kingdom, and the U.S. federal government’s National Institute of Health. The H.G.P.’s leaders are the N.I.H.’s James D. Watson, his successor Francis S. Collins, and John. E Sulston, director of the Sanger Center in Cambridge, England. They have made it a point of seeking out international collaborators. These include experts in Germany, France, Japan, and China, all of whom have made important contributions to the recent success of the project.† A quick history it may be, but it is an extremely important one. As you can tell by the date of its beginning, the Human Genome Project is not very old by scientific standards, yet even though it may seem to be very young, the developments that have been made since its creation have been quite impressive. Personalized medicine is not very far away. This will mean that there will be drugs tailored to the individual genetic makeup of the patient, thus enhancing the effectiveness of treatments for ailments like cancer, heart disease and some forms of mental illness (Cahill). Someday, we will most likely be able to intervene in germ cell or embryos to remove or change a gene (Cahill). â€Å"Issues of confidentiality and social control take these questions a step further, into economic and political realms,† referring to whether or not genetic information will be completely private or available to others such as family members, insurance agencies, and even employers (Cahill) This last issue brings me to the next article that I read. In Jeffrey Kluger’s, â€Å"Who owns our genes?
