Women, Beauty and Self-Esteem Essay -- Body Image & Self Esteem
Ambrose Bierce (1958) once wrote, ââ¬Å"To men a man is but a mind. Who cares what face he carries or what he wears? But womanââ¬â¢s body is the woman.â⬠Despite the societal changes achieved since Bierceââ¬â¢s time, his statement remains true. Since the height of the feminist movement in the early 1970s, women have spent more money than ever before on products and treatments designed to make them beautiful. Cosmetic sales have increased annually to reach $18 billion in 1987 (ââ¬Å"Ignoring the economy. . . ,â⬠1989), sales of womenââ¬â¢s clothing averaged $103 billion per month in 1990 (personal communication, U.S. Bureau of Economic Analysis, 1992), dieting has become a $30-billion-per-year industry (Stoffel, 1989), and women spent $1.2 billion on cosmetic surgery in 1990 (personal communication, American Society of Plastic and Reconstructive Surgeons, 1992). The importance of beauty has apparently increased even as women are reaching for personal freedoms and economic rights undreamed of by our grandmothers. The emphasis on beauty may be a way to hold onto a feminine image while shedding feminine roles. Attractiveness is prerequisite for femininity but not for masculinity (Freedman, 1986). The word beauty always refers to the female body. Attractive male bodies are described as ââ¬Å"handsome,â⬠a word derived from ââ¬Å"handâ⬠that refers as much to action as appearance (Freedman, 1986). Qualities of achieveà ment and strength accompany the term handsome, such attributes are rarely employed in the description of attractive women and certainly do not accomà pany the term beauty, which refers only to a decorative quality. Men are instruà mental, women are ornamental. Beauty is a most elusive commodity. Ideas of what is beautiful vary across cultures and change ... .... Journal of Behavioral Medicine, 10, 129-38.

Case Study-Barclays
BARCLAYS: MATT BARRETTââ¬â¢S JOURNEY ââ¬â WINNING HEARTS AND MINDS I. DISCUSSION QUESTIONS, CASE INTRODUCTION AND KEY POINTS Introduction The case covers the introduction of Matt Barrett as CEO of Barclays and the changes he introduced to the organization to maintain its competitive position within the retail financial services industry. In an increasingly competitive environment, Barclays is losing ground due to its lack of data-driven actions and small global presence. The case outlines the actions taken by Barrett to transform some of the key characteristics of Barclaysââ¬â¢ corporate structure, and concludes by presenting the challenge he will face in getting management buy-in in order to implement his vision. The key challenges that Barclays faces include: market consolidation, the emergence of the Euro and European Central Bank, increased reliance on IT and web-based platforms, and the rigidity of its own corporate structure. II. EXTERNAL ENVIRONMENT ANALYSIS Summarize the external environment, including conditions in the general, industry, and competitor environments. a. The General Environment Definition: The general environment is focused on the future and can be analyzed by considering the STEEP framework: Social/demographic, Technological, Economic, Environmental/geographic and Political/legal/governmental factors at play. 1. 2. 3. 4. 5. Social/Demographic Technological Economic Environmental/Geographic Political/Legal/Governmental Discussion Question 1: Perform a STEEP analysis to understand the general environment facing Barclays. How will Barclays be affected by external factors? In particular, what will the effect of globalization be in terms of threats and opportunities? Social/Demographic Segment ? English is becoming increasingly the world-wide language of business offering Anglophone Barclays opportunities to expand into international markets with reduced language barriers. BARCLAYS |1 BARCLAYS: MATT BARRETTââ¬â¢S JOURNEY ââ¬â WINNING HEARTS AND MINDS Technological: ? ? ? Increased world-wide reliance on IT and the emergence of web-based solutions in 2000 will elevate Barclaysââ¬â¢ need to diversify portfolio offerings. Barclaysââ¬â¢ must update its ââ¬Å"woefully inadequateâ⬠Management Information Systems (MIS) and begin to automate labor intensive processes to reduce costs. In order to enter new markets to increase revenues and satisfy institutional investors, Barclays must invest in increased technology capabilities. Economic: ? ? ? Robust economic environment due to tech boom will increase liquidity in the marketplace. As a result, acquisitions will be more costly than in a down economy. However this will also cause capital to be more accessible. Market trends towards consolidation will pressure Barclays to regain its industry leadership position through acquisition. Globalization and world economy flattening will require Barclays to become a global company expanding its offerings beyond its current UK focus. Environmental/Geographic: ? Geographic borders and distances between countries are shrinking with increased technology and a globalized economy. This will both require and facilitate Barclaysââ¬â¢ global presence. Political/Legal/Governmental: ? ? Emergence of the Euro and strengthening of the EU will reduce FX exposure for the European markets and stabilize European economies. European Central Bank will control interest rates in Europe making Barclays more vulnerable to its decisions (versus the decentralized banks prior to the Euro emergence). With an ever increasing number of banks operating across both political and geographic borders, Barclays must expand its reach beyond the UK to remain competitive and avoid a potential takeover. In doing this, Barclays must consider a set of threats and opportunities that are involved with operating outside the UK: Threats 1. Operating a multinational corporation involves managing across multiple cultures, languages, and economic environments ââ¬â Barclaysââ¬â¢ organizational structure must be flexible enough to adapt to these. . Low brand recognition internationally would make competition against local institutions costly. BARCLAYS |2 BARCLAYS: MATT BARRETTââ¬â¢S JOURNEY ââ¬â WINNING HEARTS AND MINDS 3. Relocation abroad requires high infrastructure costs. 4. Locating Barclaysââ¬â¢ and its customersââ¬â¢ assets across multiple currencies exposes both to fluctuations in exchange rates. 5. Failed expansion into foreign market might damage brand image and alienate n ew customers. Opportunities 1. Increased global reach and brand presence. 2. Diversified risk. 3. Possibility to create new revenue streams through new customer acquisition. 4. Gain first mover advantage in emerging markets. 5. Increases attractiveness of Barclays to multinational corporations. b. The Industry Environment Definition: An industry is a group of firms producing products that are close substitutes. In the course of competition, these firms influence one another. Typically, industries include a rich mixture of competitive strategies that companies use to pursue above-average returns. In part, these strategies are chosen because of the influence of an industryââ¬â¢s characteristics. Compared with the general environment, the industry environment often has a more direct effect on the firmââ¬â¢s strategic competitiveness and above-average returns. The industry environment is the set of factors that directly influences a firm and its competitive actions and competitive responses. Porterââ¬â¢s 5 Forces Model is a powerful tool for understanding the dynamics amongst the five key factors that determine an industryââ¬â¢s level of rivalry and profit potential. [Outlined below, High=H; Medium=M; Low=L] 1. 2. 3. 4. 5. Threat of New Entrants (or barriers to entry) Supplier Power Threat of Product Substitutes Buyer Power Intensity of Rivalry Discussion Question 2: Use Porterââ¬â¢s Five Forces Model to analyze the retail financial services industry in the UK. Given this analysis, is the industry attractive or unattractive? The below Porterââ¬â¢s 5 forces analysis shows that the retail financial services industry in the UK is a potentially attractive industry due to low threat of new entrants, supplier power, and substitutes. On the other hand, medium buyer power and high rivalry within the industry could inhibit return possibilities. Threat of New Entrants (or barriers to entry): Low ? ? High infrastructure costs Barclays has high brand recognition within the UK, less so in its other markets BARCLAYS |3 BARCLAYS: MATT BARRETTââ¬â¢S JOURNEY ââ¬â WINNING HEARTS AND MINDS ? ? Regulatory and security issues make market entry complicated for smaller players NOTE: Mergers of existing banks, if considered ââ¬Ënew entrantsââ¬â¢, must be addressed given the consolidation trend existing in the market. Smaller regional banks could pull customers away from Barclays if they were to merge and offer more extensive services but retain local roots and connections. Supplier Power: Low ? Switching costs among IT suppliers low in a fragmented industry Threat of Product Substitutes: Low ? Traditional, paper based, systems have become outdated and are no longer feasible. Asset management advice is preferred by customers over DIY Buyer Power: Medium ? ? Price sensitivity of retail consumer (major revenue stream for Barclays) relatively high compared to that of corporate client Switching costs of retail consumer (major revenue stream for Barclays) relatively high compared to those of corporate client Intensity of Rivalry: High ? ? Customer loyalty and brand recognition make switching of banking provider less likely Large number of competitors within the retail banking space NOTE: Competition within the industry is based on both price and services The Competitor Environment c. Definition: The competitor environment is the final subject of analysis required to gain a full understanding of the company's external environment. A competitor analysis focuse s on each company against which a firm directly competes and involves gathering and interpreting information about its competitors. Competitive rivalry is the ongoing set of competitive actions and responses that occur among firms as they maneuver for an advantageous market position. Especially in highly competitive industries, companies constantly jockey for advantage as they launch strategic actions and respond or react to rivalsââ¬â¢ moves. It is important to understand competitive rivalry because it influences a firmââ¬â¢s ability to gain and sustain competitive advantages. 3 Iââ¬â¢s Framework Leveraging the 3 Iââ¬â¢s framework provides a thorough overview by grouping competitors into three buckets: immediate competition, impending competition, invisible competition. BARCLAYS |4 BARCLAYS: MATT BARRETTââ¬â¢S JOURNEY ââ¬â WINNING HEARTS AND MINDS 1. Immediate Competition: Immediate competitors to Barclays are considered to be the major financial institutions located in the UK such as Lloyds TSB and RBS. These institutions are gaining increasing presence over Barclays due to their lower cost structures and improved efficiencies. 2. Impending Competition: Impending competitors to Barclays include international financial services firms such as Credit Suisse First Boston, and smaller firms operating in one of Barclaysââ¬â¢ business categories such as investment advisory firms (Zoete Bevan, Wells Fargo Nikko). . Invisible Competition: Barclaysââ¬â¢ invisible competitors include smaller UK based businesses that focus solely on a product offered by one of Barclaysââ¬â¢ divisions, such as smaller mortgage lending businesses (Woolwich). III. INTERNAL COMPANY ANALYSIS Summarize internal company factors including: capabilities and weaknesses, value chain activities, strategy, and financial situation. a. Outline the company's internal capabilities and weaknesses. Definition: Capabilities exist when resources have been integrated to achieve a specific set of tasks and are frequently developed within a specific functional area. In addition to identifying the company's opportunities and threats from the external environment, another important objective of the situation analysis is to evaluate strengths and weaknesses as input for developing the company's strategies. Discussion Question 3: What are the main capabilities of Barclays? Does Barclays have a core competence? Barclaysââ¬â¢ main capabilities include retail financial services and corporate banking within the UK. The companyââ¬â¢s core competencies (i. e. trengths relative to competitors that give it a competitive edge) include: a strong brand presence within the UK, a strong domestic franchise, new innovative leadership under Matt Barrett, and outstanding (276%) market cap growth from 1995-2000. BARCLAYS |5 BARCLAYS: MATT BARRETTââ¬â¢S JOURNEY ââ¬â WINNING HEARTS AND MINDS Discussion Question 4: Create a SWOT analysis to understand Barclaysââ¬â¢ strengths and weaknesses. Does Barclays have a sustainable competitive advantage in the re tail financial services industry? If so, what is the source? Strengths 1. Strong brand presence within UK 2. 76% growth in market cap from 19952000 3. Strong domestic franchise 4. Strong new leadership with strategic vision (Matt Barrett) Opportunities 1. Opportunity to expand into global markets (Barclays Global Investors only 2% of business) 2. Ability to strengthen existing brand presence within Europe (10% of sales and profits) 3. Streamline cost sharing among business units (HR, IT, Finance, etc. ) Weaknesses 1. Cost to income ratio significantly higher than competition (business units operate as silos) 2. Narrow focus (61% of revenue from RFS, capital division focused on debt products) 3. Limited global presence (80% of profits from UK) Threats 1. Management reluctance to embrace new strategies, demoralized staff 2. Competitors have lower cost advantage 3. Stronger global presence of international competitors 4. Dissatisfied institutional investors 5. Inadequate IT systems can inhibit growth Barclaysââ¬â¢ competitive advantage includes its: strong presence within the UK market both in terms of locations and brand recognition, strong innovative leadership, and international presence. Barclaysââ¬â¢ business strategy has focused on growth within the UK and has not invested enough capital into international expansion. In a globalizing economy with rising multinational financial corporations, the lack of a strong international presence is something that could significantly hurt Barclays in the long-term, and even turn it into a takeover target as institutional investors continue to lose faith in the company. b. Conduct a Value Chain analysis to identify value-creating activities. Definition: By exploiting its core competencies, a competitive firm creates value for its customers. Value is measured by a productââ¬â¢s performance characteristics and by its attributes for which customers are willing to pay. Companies with a competitive advantage offer value to BARCLAYS |6 BARCLAYS: MATT BARRETTââ¬â¢S JOURNEY ââ¬â WINNING HEARTS AND MINDS customers that is superior to the value competitors can provide. Value is created by innovatively bundling and leveraging resources and capabilities. A value chain analysis provides information relative to primary (inbound/outbound logistics, operations, marketing & sales, and service) and secondary (firm infrastructure, human resources mgmt, technological developments and procurement) activities. A value chain representation of Barclaysââ¬â¢ primary and support activities is presented in the diagram below. This information can be used to establish a business strategy which targets select activities to create a sustainable competitive advantage. Primary Activities ? ? ? ? Inbound/Outbound Logistics: N/A Operations: o Strong focus on Retail Financial Services (RFS), account for 61% of revenue o Sold cash, equities, and corporate finance businesses to focus on debt products Service: N/A Marketing and Sales: o Strong focus on UK market and low global presence o Reliance on UK brand recognition Support Activities ? ? ? HR Management: o Executive committee not performing as decision making team o Higher than average staff expenses put heavy strain on cost structure Technology Development: o Management Information Services (MIS) system is outdated and inadequate Firm Infrastructure: BARCLAYS |7 BARCLAYS: MATT BARRETTââ¬â¢S JOURNEY ââ¬â WINNING HEARTS AND MINDS o Divisions operating as silos (each has own HR, IT, etc. ) o Lack of data driven decision making processes o Introduction of the Euro and the European Central Bank affect Barclaysââ¬â¢ exposure to foreign exchange as well as interest rate changes both for the company itself and its clients Procurement: N/A Discussion Question 5: Which components of Barclaysââ¬â¢ value chain have made the company successful thus far? What changes to Barclaysââ¬â¢ organizational structure and focus are necessary for Barclays to remain competitive? Barclays has become a major player in the banking industry through strong brand presence within the UK, earning it one out of every five personal customers, and a clear focus on Retail Financial Services (RFS). However, both its UK presence and RFS focus have failed to provide a sustainable competitive advantage for the company. In order to remain competitive within the banking industry, Barclays must examine and redesign various components of its value chain including: 1. Focus on Retail Financial Services: a. Barclays must expand its focus beyond RFS by creating new product offerings for corporate customers and further expanding internationally to give newly acquired corporate customers global access. 2. Outdated and inadequate MIS system: a. In order to manage its internal functions efficiently, Barclays must adopt technological innovations and update its MIS system. 3. Lack of data driven decision making: a. In order to compete in an industry driven by statistics and analytics, Barclays must emphasize data driven decisions throughout its corporate structure. 4. Fragmented core divisions: a. Operating fragmented core divisions such as HR and Finance creates additional costs as well as bureaucracy and inefficiencies. Barclays must consolidate these shared services. BARCLAYS |8 BARCLAYS: MATT BARRETTââ¬â¢S JOURNEY ââ¬â WINNING HEARTS AND MINDS c. Financial Analysis Definition: Financial analysis is used to assess the viability, stability and profitability of a company or operating division. The analysis is done using quantitative historical performance found in the financial reporting documents (Balance Sheet, Income Statement, and Statement of Cash Flows). The goal of the analysis is to understand a companyââ¬â¢s financial health through its profitability, solvency, liquidity, and stability. Given the financial information provided in the case, it is clear that Barclays is lagging behind its competitors in cost control measures, and has allowed both PP&E and Staff Expenses to rise above its competitorsââ¬â¢ average. Operating expenses as % of income In addition, an analysis of the companyââ¬â¢s divisions and their respective earnings contribution reveals that Barclays heavily relies on its Retail Financial Services division for a large portion of its earnings; this suggests that diversification might be needed. NOTE: Further analysis into the average contribution of each revenue stream for other players in the industry is needed before diversification can be e ntirely justified. BARCLAYS |9 BARCLAYS: MATT BARRETTââ¬â¢S JOURNEY ââ¬â WINNING HEARTS AND MINDS IV. STRATEGY FORMULATIO N Summarize Barclaysââ¬â¢ strategic position as it relates to its current strategy and the components thereof. a. Summarize Barclaysââ¬â¢ current strategy. Barclaysââ¬â¢ current strategic objective is to drive profits by consolidating internal functions and expanding its international presence. The company is a major player in the UK financial services and retail banking industry but has lost ground internationally despite rapidly rising market capitalization. Fragmented internal divisions and a lack of aggressive expansion have brought up the need for extensive managerial and structural changes to the firm. This prompted the hiring of a new CEO, Matt Barrett, who established a series of restructuring goals for Barclays to remain competitive. b. Strategic Analysis Definition: Conduct an analysis of Barclaysââ¬â¢ business strategy by using the 4 Pââ¬â¢s Framework. The 4 Pââ¬â¢s Framework is used to understand a companyââ¬â¢s strategy based on its Position (Mission, Values, and Vision), Priorities, Payments (what it will spend its money on to reach those priorities), and Performance (how it will measure success). By completing the framework, we can analyze a companyââ¬â¢s current, future, or recommended priorities as well as set forth a path in order to achieve goals and measure accomplishments. Use the 4 Pââ¬â¢s Framework to analyze the firmââ¬â¢s past/current/future strategy. 1. Position a.

The American Civil War - 1303 Words
The American Civil War began on April 12, 1861, and ended on May 9, 1865. There were over 600,000 casualties from this war. Slavery was the main issue at the beginning of the war. The war occurred after Southern slave states broke away and formed the Confederate States of America. Many young Northern and Southern boys served in the Civil War. Anywhere from 250,000 to 420,000 boys may have fought in the Civil War. After the fall of Fort Sumter, President Abraham Lincoln issued a call for seventy-five thousand volunteers. Many children joined the army because they were either runaways, orphans, or they wanted to fight beside their brothers and fathers. Most boys from the North did not join the army because they wanted to get rid of slavery. One boyââ¬â¢s comment was, ââ¬Å"I do not know anything about it, whether it is a good thing or a bad thing and when talk gets around to it I say very littleâ⬠(Murphy 8). Many Northern boys joined because they wanted to put the South in its place. Northern boys also wanted to escape the boring routine of farm life. Most boys from the South joined the army to take part in an adventure, and they wanted to fight the Yankees. The Southern boys also wanted to defend their homes from the invading army. One Southern boy said, ââ¬Å"I would rather die than become a slave to the Northâ⬠(Murphy 8).

`` Because I Could Not Stop For Death `` - 880 Words
Death is an aspect of life that everyone becomes acquainted with sooner or later. The poem, ââ¬Å"Because I Could Not Stop for Death,â⬠by Emily Dickinson, is seen as a reflection of the passing of time in one s life while living. No one knows when it is their time to die, and we live everyday as if tomorrow it promised. Dickinson is saying that since we as humans tend to live on the expectation for tomorrow, we don t think about the end of our life or when it will be. That time will stand still when, and only when, life draws to a close, yet it will no longer matter. Dickinson starts the first stanza of the poem with, ââ¬Å"Because I could not stop for Death ââ¬â He kindly stopped for meâ⬠(807). Clearly she was not ready to go, death simply took her by surprise and brought her busy life to a halt. This could be seen as a beautiful way to take on death because death is usually said in such a morbid tone and the fact she associated ââ¬Å"kindlyâ⬠with death makes it beautiful. The second line says, ââ¬Å"The Carriage held but just Ourselves ââ¬â and Immortalityâ⬠(Dickinson 807). The author emphasizes Carriage, Ourselves, and Immortality. Dickinson seems to be talking about her own death chariot and by immortality, she believes her death is not the end, but rather as a step to eternal life. She continues in the second stanza with, ââ¬Å"We slowly drove ââ¬â He knew no haste and I had put away my labor and my leisure tooâ⬠(Dickinson 807).

Review Of Literature Employee Performance Measurement
Question: Discuss about theReview Of Literaturefor Employee Performance Measurement. Answer: Introduction Performance measurement is a complex area for business leaders. Organizations need to measure the performance of their employees, and using this, decide on their career path and fair compensation. In a typical organization, the performance measurement is an annual activity. Employees are assessed on their performance, usually using written forms and lengthy discussions between leaders and the employees. These appraisals are conducted in batches, and take a long time to complete, taking, as in the case of Deloitte, millions of hours every year. Deloitte has come up with a new method of performance measurement that does not look at past performance as the basis of employee performance and future prospects. It has also decided that batched appraisals are not as representative as they should be, if they were to be done as performance happens. Due to this, and the need for employers to constantly align their employees performance to the overall strategy of the organization, which involves examining employees performance in terms of expected future performance, rather than historical data. In this, the authors determine that a drastic change in appraisal is needed, which will be more objective. Current objectivity tests are highly dependent on the rater, sometimes as much as 62%. This should therefore be changed to reflect more on other aspects of an employee. Secondly, performance measurement should be geared towards the need to have employees utilizing their strengths, by focusing on their skills. In terms of performance, the organization needs to have a standard and fair way that helps in defining and recognizing performance. Change The assertions above by Buckingham and Goodall (2016) on performance are also echoed by Watts and McNair-Connolly (2012), who believes that organizations should measure performance depending on their specific circumstances. Generalized performance measures that only happen periodically, and long after the performance has been delivered, are unlikely to give a true measure of the employees ability. Watts and McNair-Connolly chronicle changes in performance management and measurement, using such instruments such as a balanced scorecard, key performance indices, and the application of smart objectives. However, Watts contends that these measures are all meant to measure past performance, and use it as an indicator of what to expect. This is what Buckingham and Goodall (2016) had argued against, saying that historical performance is hardly dependable in showing how well employees will perform in future situations, when their roles are aligned to more closely match organizational objectiv es. Ratings and Objectivity Mughal, Akram and Ali, (2014) have also explored the weaknesses associated with ratings and forms of performance measurement in organizations, in their case focusing on the Alfalah Bank. According to their analysis, the bank has been enjoying low motivation of its employees. This demoralization has been linked strongly to the performance measurements that the organization employs. The performance management system is such that it does not provide for a proper reward system, meaning that highly performing individuals feel that their performance goes unrewarded. Performance measurement issues are widespread in the banking sector, as they are in other services industries. This problem is in part brought about by the insistence on employees appraisals to be done by their managers, meaning that the objectivity of the report on appraisal is severely compromised. For instance, if an employee enjoys good relations with the manager, their report is likely to be favorable. If, on the other han d, relations are not so positive, the employee may suffer a negative appraisal, and potentially derail their career. At the same time, ratings are too simplistic, as Buckingham and Goodall (2016) show, meaning that they may fail to capture some key performance areas. Strengths Orientation Dobre (2013) is also an advocate of organizations that try to utilize employees strengths, seeing it as a major source of motivation for employees. Dobre adopts Theory Y by McGregor to describe this importance. The theory sees a pleasant work environment where employees welfare is well taken care of, and in which their goals are well aligned with those of the organization. Productivity levels are likely to be high and turnover low when the organization enables them to do what they are best at. This is best seen when the employees feel that the organization actually values them, and believes they can be self motivated and self directed in pursuing goals the organization cares about. In short, motivated people work hard to achieve their own goals. When this is well aligned with organizational goals, the organizations performance is more likely to be achieved. Talent dependent companies such as Deloitte are more likely to see the sense in applying this approach. Definition, Recognition and Compensation of High Performance According to Buckingham and Goodall (2016), there is a strong correlation between compensation and high performance, especially when such compensation is in recognition of exemplary performance and the value an organization places on the employee. Compensation does not only involve monetary rewards, but indirect compensation as well. This involves things such as paid holidays and other perks. Companies need to come up with a clear and simple method of measuring performance, and accurately correlating it to compensation. This way, it will be clear that better performance will automatically lead to higher reward, and such an employee will be valued by the organization (Hameed, 2014). References Buckingham, M.

Visible Light Communication
Question: Describe about the Visible Light Communication? Answer: Introduction Visible Light Communication (VLC) falls in the category of the highly developed technology of the optical wireless communication division, in this visible region (0.375um-0.780um) light is utilized as a data transmission medium with enhanced security and higher data rates features in comparison to the predictable technologies similar to Wi -Fi, Wi-max etc., which accomplish the communication by the radio waves. While making use of wireless internet the system bandwidth got bothered at the lower data rate or slow speeds frequently in the case of multiple devices using the same network. To conquer the lack of bandwidth we can make use of light for data transfer and the process is called as ILLUMINATION DATA . The thought at the back is that, infra-red remote is somewhat customized i.e., LED light bulb that bring intensity contrasts which cannot be tracked by normal human perception. It is probable to encode the data in the light by modulating or altering the light to make the LEDs flic ker and make it on and off to provide the binary strings of 1s and 0s.At the same time as using combinations of green, blue and red LEDs to change the frequency of light encoding a dissimilar data channel. System Components It utilizes fast changing light pulses to send out the information wirelessly. The major parts of this system of communication are A high intensity white LED, that is the source of communication A photodiode is made up silicon having high-quality visible wavelength response region which is acting like the receiving element. Amit rawat Switching the LED in the on and off mode is done to produce binary 1s and 0s strings. Encoding of data can be performed in the light to produce a novel stream of data by changing the LED flickering rate. To be precise, through the process is about modulation of the data signal using the LED light, the illumination of the LED light can be utilized like a source of communication. Due to the fast flickering rate, the output at the LED end comes into view like a constant light to the naked eye. Using suitable techniques for multiplexing it is possible to have data rate more than 100 Mbps. In case of parallel data communication the VLC data rate can be augmented. In this each LED transmits a dissimilar data stream and combined forms an array. LED Model Fig. 1 demonstrates the standard demonstrator block diagram. The link contains of two DSP boards first one is transmitter (Tx) and second is the receiver (Rx). In exacting, the evaluation board of TMS320C6000 DSP using Texas Instruments C6713 based on floating-point processor that is structured of VLIW very long instruction word architecture is utilized. Speed of processor is 250MHz. The evaluation boards has 32-bit stereo analogue output and input port with a utmost sampling frequency 96kHz. Fig.1 Visible light data transmission prototype For the function of exhibition, data source of digital image is utilized. The produced D/A (digital/analogue) changed modulation signal from the correspondent DSP is feeder to the circuit of optical transmitter which constrains the white LED. At the end of receiver, a circuit containing a photodiode is utilized to change the signal of optical range to the signal of electrical domain. The converted signal is then conceded through an ADC converter trailed by elimination of cyclic prefix and process of demodulation. These processes are headed by a frame synchronization routine Fig.2 VLC test-bed system using an array of 16 resonated white LEDs. Concept Illustration The VLC transmitter has components like a power supply, an amplifier, a bias-T. The receiver includes a PIN type diode as a photo-detector or APD or Avalanche Photo Diode. LED acting as a source of light from the transmitter side produces visible light radiation and then absorbed by the receiver all the way through free space spread. The signal source and a terminal analyzer component is made up of two-port network analyzer, giving output in form of a small sine wave and calculating the received amplitude too. The LED modulation bandwidth is limited with the frequency of response. Though, the lifetime of the minority carriers in semiconductors have an effect on this reaction frequency. Consequently, there exists a limit on the LEDs theoretical bandwidth upto 2 GHz. at present; the practical LED bandwidth is much lower than this limit of theoretical value. Therefore, the resulting LEDs lower modulation bandwidth influences its function in the communication with the high-speed bandwidth. Results and Discussion For analysis consider the three different LEDs which are further separated into three categories, which were calculated using same intensity of light, and after that the only variable is the current density. Consequently, the consequences can straightly replicate the association of the 3 dB LED bandwidth and current density. In below Figure 3, the Y coordinates gives amplitude, tells that the proportion of power at output and power at input and it reproduces the LEDs 3 dB bandwidth. Since noise is present in the background the curvature in Figure 3 shows big fluctuations. Although, these curves with non-smooth nature does not moving the in general experimental results trends. As given in figure 3 that the LED As 3 dB bandwidth was 10.5MHz if the biasing current is 20 mA and the significance quickly increased to value of 44MHz for the biasing current of 100mA. In adding, the other LEDs B and C also established this regulation and the consequences were revealed in Figures 3(b) and (c), correspondingly. Consequently, the calculated 3dB bandwidth of three dissimilar sizes LEDs were all enhanced considerably with the amplified current density. This occurrence can be established with the probability of bimolecular recombination, that was relative to the carrier density of injected into the dynamic volume. Fig. 3 The normalized frequency response of (a) LED A, (b) LED B and (c) LED C measured under different bias currents Summary and Conclusions In this report, a dimension association of modulation individuality for VLC systems is explained and the dissimilar-sized blue LEDs with different bandwidths have been accounted. The results obviously discloses alike linear association between 3dB bandwidth and its LED current density. This occurrence can be credited to the bimolecular recombination likelihood that is relative to the density of injected carrier into the dynamic volume. Consequently, growing the LED current density is a possible method in VLC systems to improve the rate of data transmission. Furthermore, this experiment demonstrates that series resistance of high value is one main concern that puts restriction on modulation speed of LED. Therefore, additional study will spotlight on optimizing layout of device in addition to dropping material bulk resistance to decrease the resistance. References 1. H.L. Minh, D. OBrien, G.
