Good eating regimes and frequent exercise are not only touted to be effective in increasing wellness, but also in managing stress. The following paper will focus on exercise, eating well, and increasing fitness as strategies of managing stress and increasing wellness. World health organization has identified stress as a major problem in the current world that is affecting both mental and physical health (Varvogli & Christina 76). Exercise is known to trigger a relaxation reflex on the brain that enables relief stress. Therefore, it is clear that exercise is a better way of reducing stress other than using pills and alcohol that people resort to when trying to hide from stress. The best exercise known to reduce stress is geared towards improving focused breathing, blood flow to the brain and muscle, and mindfulness meditation, all which are geared towards relaxation of mind. Good eating regimes are key to stress relieve and wellness of the body. Good eating habits and strategic exercising helps pregnant mothers and terminally ill people to regain their health easily and maintain normal body function optimally (Parker & Samson 10). Nutritional balance can be achieved by checking what people eat in the morning, lunch, and supper. Nutrition is a key component of the livelihoods on individuals, and if not observed well, then people are destined to fall sick. Currently, there are many obese children in the society signaling the relaxed nature of the upbringing system that no longer recognizes the need to keep fit. The stigma usually geared towards these obese kids usually stresses them unnecessarily. The terminally ill people in the society including cancer and HIV/AIDs patients have been shown to be the people under the highest degree of stress. A breakfast rich in cereal meals is known to counteract stress in

African Americans jazz Essay Example for Free

African Americans jazz Essay Many believe that jazz is a music that African Americans played together with the Creole musicians during the 19th century in New Orleans, Louisiana in United States that bind the race together, black and white Americans. This is also considered as the ancient and most distinguished musical genres in North America and known as â€Å"America’s classical music. † Based from the quote of Gerald Early, a lecturer and a writer of African – American studies, he emphasizes that America will be known from three things: in the Constitution, sports (baseball), and in jazz music, since these are the most captivating things that they developed. Jazz is a type of lyricism that reflects on the Great American promise and expresses hope for freedom in slavery. It is also illustrated by the exceptional attribute of collective improvisation and should be performed with the right feelings about it. According to Louis Armstrong if you will ask, you’ll never know. He discovers the secret behind the jazz music, that’s why he became known as one of the successful musicians and leading stars in the whole world. The early jazz musicians create a great impact to the life of many as they change their point of view towards music. Although, jazz music is originated from the black, who are considered outsider but living in America, wherein they use this as a passage to be accepted in the society, still America truly owns this music. I prove it accurate because the New Orleans jazz musicians improve, develop, and patronize this music until the whole world has known it. One more thing, jazz has a big role to the history of America. This music becomes the expression of freedom because way back in 1970, it played a major role in the life of African American culture. Their longing for freedom is emphasized as they sing. I also believe that jazz eliminates the discrimination between the white and black people, that’s why I strongly agree that jazz belongs to America because the whole history of this country is the song itself. The history of jazz is deeply rooted in America and until now the musical tradition lives here.

Huawei UCN Research and Practice

Huawei UCN Research and Practice A NEW CONCEPT In recent years, DSL systems have faced many new challenges, such as crosstalk. The standardized DMTs modulation techniques are deployed more densely than ever, making radio resources allocation a severe challenge to address. Insertion of additive guard bands like cyclic prefixes led to the addition of new deal. These insertions are not enough to simply improve the capability of a single traditional DMT transceivers to counteract the impact of the crosstalk. It lies that network development requires a new way of thinking. Based on an optimization-based perspective, next generation DMTs require coordinate network nodes, frequencies and bands, and uniformly arrange network resources, and capable to provide optimal user experience. Therefore, Huawei established a new concept: User Centric Network (UCN). User Centric Network (UCN) is a concept of user-centric network construction. In traditional network construction, base stations were centered, and users were served by a certain base station. As users may be located in different places, it is a challenge to ensure stable and reliable performance for users. Interference between adjacent base stations also reduces the resource efficiency of the entire network. With the new concept of UCN, resources are coordinated, combined, and optimized in allocation, based on a user-centric philosophy so that the user experience will be enhanced. UCN is also a new user-centric concept in term of operation. In the traditional way, operators can just sell simple data packages to customers. USER BENEFITS UCN focuses on users it can provide a lot of benefits for end users. First, UCN can eliminate cell boundaries, providing noborder service experience and improving the peak and average rates. Second, UCN enables multiple cells to receive signals from terminals in a coordinated way, reducing requirements for transmit power of terminals and prolongs their standby time. Third, UCN uses flexible networks, providing customized services and tariff packages for users. UCN AND 4.5G, 5G Here we have to emphasize that UCN is a network construction concept beyond the definition of wireless technology generations. UCN and 4.5G or 5G are not simply a one-to-one relationship. UCN can be implemented phase by phase in 4.5G and 5G. For example, UCN technologies can be used in the 4.5G phase, such as distributed MIMO. Distributed MIMO uses distributed, multi-site, multiple antenna beamforming and multiuser multiplexing technologies on the RAN side to reduce interference and increase capacity. In the recent field trials, distributed MIMO proved 3- to 4- folds of cell capacity. RECENT RESEARCH ON UCN At present, the number of base stations deployed on 4G networks has reached several millions. The recent research on UCN focuses on how to apply the leading-edge UCN concept to these base stations early. We are pleased to see that the entire industry has made successful progress in UCN research. CloudRAN-based technological innovation such as distributed MIMO can ideally control intersite interference and enable extremely dense deployment of sites, without the need to upgrade terminals on live networks. 4.5G distributed MIMO has been put into trial use on live networks for advanced operators. For example, the inter-site distance of lamp pole sites on Shanghais Bund is as short as 50 m. With distributed MIMO, the data rate of cell edge users has increased from 8.2 Mbps to 15 Mbps, an improvement of 80%, and the average cell throughput has increased from 45 Mbps to 65 Mbps, an increase of 45%. Minimum Mean Square Error (MMSE) Estimation for Interference Identification We are interested in an estimate of the time-varying channel gain matrix. It is obtained by means of a statistical estimation approach that combines the measurements with (i) statistical knowledge of measurement uncertainty, and (ii) prior knowledge of spatial correlation of the interference links. We assume known positions of the transmitted and received vectors and known noise vectors from which the a priori distribution of the channel gain matrix with a mean and a covariance matrix is derived. Statistical knowledge about the channel gain vector and measurement uncertainty is exploited. Given some physical-layer measurements, an ideal linear model in which the prior distribution of the interference matrix and the uncertainty distribution is Gaussian in linear scale is derived. This model relates the measurements to the channel gain vector and therefore can be used to derive an optimal linear MMSE (LMMSE) estimator for the channel gain vector. Since interference is often assumed to have a log-normal distribution, a more realistic model in which the prior path-loss distribution is log-normal and the uncertainty distribution is Gaussian in dB scale is used. In this case, the model becomes non-linear, and therefore a closed-form linearized MMSE estimator, named linearized log MMSE (LLMMSE), is derived to estimate the channel gain vector. The results presented here show how the accuracy of interference estimation obtained from the proposed MMSE Estimator is affected by two syste m parameters, namely the Reference Signal Received Power (RSRP) uncertainty à Ã†â€™ and the channel variance à Ã‚ . The performance of the MMSE is compared to the simple least squares (LS) estimator. The simulation results in Figure 2-2 show that the proposed MMSE estimator outperforms the LS estimator. The gains are large for high noise levels or when the channel variance à Ã‚  is small. The performance in low noise situations is similar to the LS performance as in such cases the solution of the MMSE estimator converges to the one of the LS estimator. Same behaviour is observed when the channel variance is high.

Voltaires Candide: The Transformation of Candide Essay -- Voltaire Ca

Voltaire's Candide: The Transformation of Candide   Ã‚  Ã‚  Ã‚  Candide (1991), which is another version of "Voltaire" by French writer Francois-Marie Arouet, is a short but diverse story that tells of a young man's journey for love and the hardships he faces all the while keeping a very strong, positive and philosophical outlook on life. The book starts in an unknown year, hinted sometime around the Renaissance, with a young man named Candide. Candide loves the princess of a Baron and is banished from the land because of it. Wanting so much to be with his love, he starts his travels to find some way that he can be with her. Right from the start Candide falls into trouble. From being forced to join an army, to seeing and loosing his love again, to great riches and to the lowest pit of poor Candide is able to overcome adversary and conquer the odds. In this amazing journey he finds that every event in the world has a reason, and whether there are positive or negative moments you have to live them.   Ã‚  Ã‚  Ã‚  At the beginning, the reader finds out about Candide's misfortunate event that leads him on his journeys. His being taught, by Pangaloss, of philosophical ways of life leads him to long for his beloved. This longing is the official start of his journey to marry the beautiful Cunegonde.   Ã‚  Ã‚  Ã‚  Candid finds himself at the first of his woes when he enters a tavern in the town of Waldberghofftrarbk-dikdorff. He is coaxed into going to a camp by mean of a meal. In the camp he is captured and forced to fight for the Bulgarian army. He attempts to escape but is caught and is forced to run the gauntlet. He then tries escaping again in the heat of battle and succeeds.   Ã‚  Ã‚  Ã‚  After being taken in and helped by James, an anabaptist, he runs into h... ...on: if you had not walked over America: if you had not Stabbed the Baron: If you had not lost all of your sheep from the fine country of El Dorado: you would not be here eating preserved citrons and pistachio-nuts" (87). This last quote by Pangaloss is the end of Candide's journey. This is where Candide finally realizes that the events in the world have reasons behind them.   Ã‚  Ã‚  Ã‚  Candide realizes, through the teachings of Pangaloss and his journeys, that no one can change what has happened or what might happen in the near future. The only thing that can be done is to take life as it is dealt and play the hand you got. This is a major change for Candide philosophical thoughts of events from beginning to end. Candide can now make the bast out of events that may not favor him in the future. Works Cited Voltaire. Candide. Dover Publications, Inc. New York, 1991

The Squeaky Horn

| The Squeaky Horn| Assignment A| Company Overview The Squeaky Horn is a musical instrument repair store which specialized in all major and minor repairs for band and orchestra instruments. Over the past ten year, The Squeaky Horn has established a great customer relationship with the music professionals from all over the country, and has been operated in a relatively less competitive environment as there were no many similar stores in the town.However, as the new store Best Instrument Repair opened across the town recently, the Squeaky Horn faced a lot pressure on lowering the price for minor repairs in competing with the new price that the Best Instrument Repair offers for the similar services. Eugene Decker, one of the three owners of The Squeaky Horn, was trying to figure out the reason for losing $50745 in their planned profit from the actual operating results, with the information that the store has been going through significant changes within the year.In order to explain the change in profit, it is necessary to have a good understanding of the musical instrument repair industry from both macroeconomic and microeconomic aspects first. Industry Background Macroeconomic Analysis Canadian GDP has been showing an increase trend from 2001 to 2010 as showed in Appendix 1, even though between 2008 and 2009, GDP had a negative growth rate of 2. 8%, the 3. 3% of increase in GDP at 2010 pull up the figure again to make an overall increase trend. Because of the significant increase in GDP over the past decade, consumers have more money spend on entertainment and education.Thus, more people tend to go to watch art shows and learn to play musical instruments. If looking at Appendix 2, the first chart shows clearly that the average household spends more money in entertainment outside home in 2003 than 1998. For example, people spend $20 more on performing arts on average per year. It implies that an increasing number of people will go listen to a concert, which stimul ates performers to keep a peak condition of their instruments for better performances. The musical nstrument repair industry therefore, attracts more repair jobs and technicians in order to satisfy the increasing demand on musical instrument repairs. The average Canadian music technician’s salary is $48,000, which is $9,000 higher than the other instrument repair technician’s as showed in the Appendix 3. Beside the facts that music technicians needs spend a lot of time work on the music repair certificate in order to perform their jobs, $9,000 difference in salary makes the musical technician jobs more attractive than others. As a result, the musical instrument repair industry is competitive.At the last, the industry is also affected by researcher’s studies. According to a cross-sectional study of Canadian school children, E. Glenn Schellenberg (2006) as referred in Appendix 4, kids who play musical instrument perform better in both cognitive tasks and general i ntelligence tests. Therefore, more parents would like to have their kids learn one of the musical instruments in order to explore the kids’ IQ potential. As a result, the musical instruments repair business is much more prosperous than before. Microeconomic Analysis The musical instrument repair industry is competitive.As a pure repair store, The Squeaky Horn faces competition not only in its own town, but also across the province. Because musical instruments are fragile, long distance travel increases the possibility of instrument breaking, music professionals prefer to have their instruments repaired in the local area. Therefore, there are not so many competitions outside the province. Since a lot of musical instruments retailers and individual music technicians also provide the similar services, the overall competition The Squeaky Horn is facing is heavy.Appendix 5 offers 3 of the most popular musical instrument repairs store in Ontario. The first two stores specialized in difference instruments repairs (guitar and violin); the last one is basically covering repairs and restorations for all instruments. Appendix 5 also shows the instrument repair price that another store in the industry offers. The average major repair (overhaul and refinish) is priced over $300 for band instruments (trumpet, trombone and horn) compare to The Squeaky Horn, which shows that The Squeaky Horn is cost efficient.The Squeaky Horn has various suppliers for musical instruments parts. Appendix 6 provides all the musical instruments manufacturers across Canada, and over half of the suppliers are from Ontario. Various supplier choices make The Squeaky Horn a price maker, which allow it to lower the repair price to attract more clients. The Squeaky Horn has customers all over the country. The customer line spreads from the music professionals to amateur players, from orchestra to individual household.Since the store has been operated for more than 10 years, a lot of old customer s prefer to have their instrument repaired there because of the already-established reputation. In addition, because of the musical instrument repairs need very specific skills, and technicians normally needs to obtain certain music degree and musical instrument repair certificate in order to perform their jobs, it is relatively hard to become a musical instrument repair technicians than others. As a result, the musical instrument repairs industry has a barrier to entry. There are not so many substitutes for musical instrument repairs.Since musical instruments is considered to be expensive goods, and most individuals and families can only offered one piece of the musical instrument (ex. piano), periodic repair and examination become the most popular method to keep a peak condition of their instruments. Unless the price of music instruments become so cheap that an average music player can offer to pay a new one when they found problems with the instruments, or the second hand market become so popular that the selling price of the instrument are enough for getting a new one, people will stick on instrument repair.If comparing The Squeaky Horn’s operating result with the maintenance and repair industry’s average (Appendix 7), we will find that The Squeaky Horn’s actual revenue of $664,170 is almost as twice as much of the industry average of $334,900. However, the total actual expense is $354,070 higher (calculation is provided at the end of Appendix 7), which results the overall profit fall below the industry average of $28,100 in 2008. Therefore, The Squeaky Horn is an absolute industry leader in revenue sector, but did not do well in maintaining high profitability through expenditure control. Appendix 1: GDP and GrowthBetween 2001 and 2010, GDP for all industries in the Canadian economy increased from $1,041 billion to $1,234 billion. In each year of the period, GDP growth has been positive with the exception of 2009 in which we saw a decl ine for the Canadian economy. The compound annual growth rate of GDP between 2001 and 2010 measured 1. 7%. Gross Domestic Product (GDP) and GDP Growth: 2001-2010 Canadian Economy (NAICS 11-91) GDP growth in 2001 and 2002 was much slower, with annual growth rates below the 10 year compound annual rate. However, in 2003, annual GDP growth slipped to 2. 1, corresponding with a down-turn in the United States economy.GDP growth rates went on to rebound and remained steady around 2% and 3% until 2008, when a global recession trimmed annual GDP growth to 0. 6% falling again in 2009 to an all time low of 2. 8%. In 2010, we begin to see another rebound with the GDP growth increasing to 3. 3%.

For their homes, demand has risen for such goods as home entertainment systems an d computers.Expenditures on these services comprised 0. 44% of the average household's overall spending budget in 2003, up from 0. 41% in 1998. This shift in preferences and growth in incomes, population and prices caused the consumer market for entertainment services to expand from $2. 3 billion in 1998 to $3. 2 billion in 2003, an increase of 41%.

In a cross-sectional study of Canadian school chi ldren, E. Glenn Schellenberg (2006) found that kids who took music lessons had slightly higher IQs. The effects were general, cutting across several different intellectual abilities (e. g. , verbal, mathematical, and temporal-spatial). Music lessons were associated with abilities associated with fluid intelligence, such as †¢ Working memory †¢ Perceptual organization Processing speed They were also associated with increased verbal comprehension and better high school grades. These differences remained significant after controlling for a child’s age, nonmusical activities, family income, and parent’s education.
