Programming Example: The Length of a Parabola Segment

The values of base and height will be stored in REAL variables Base and Height, respectively. Length will be used to store the parabola segment length. Since the content in the square root is used twice, it would be more convenient to save the result in a variable. This value will be stored in temp. Since 2h also appears a few times, variable t is used to store this value. After reading in Height and Base, 2.0 * Height is computed and stored in t with the first assignment. Then, the second assignment computes the content in the square root and stores the result into temp. The third assignment compute the segment length and stores the result into Length. Note that intrinsic function LOG() is used. The four WRITE statements display the input and the results.

Target Segments

...Target Segments Demographics Through the technological advancements and the progression of the video game console industry, the demographics of the target segment for this industry has changed in many different factors. First, a frequent misconception of the customer base of this industry is the age group of the video gamers. Many believe that youth dominate the video game console industry but studies have proven otherwise. Researchers surveying the demographics in the 2012 USA market, the average ‘gamer’ is 30 years old down from 37 years old in 2011. As a matter of fact, the results presented only 32% of gamers to be under the age of 18, a declining trend initiating from 2005. This trend further opposes the conception of the core of video gamers are youth. As of January 2012, 56% of all households in the US own a console and 17% owning 2 video game consoles. This implies that the customers in the industry are increasing loyalty on the brand rather than seeking to turnover to another console. These statistics and research illustrate that the age of consumers in this industry varies than the common perception. Changes in these trends must be analyzed carefully and acted upon to increase market share. Women, families, grandparents, have all shown increases in the participation of video games. Another common misconception is the gender base of consumers using video game consoles being dominated by males. 2012 data conveys that the gamer gender demographics are......

Portal supply is generally provided by small branches originating from the left main portal vein, or from segmental branches from adjacent segments. It is drained by small hepatic veins joining directly to the anterior wall of the inferior vena cava Seg 2 displayed in yellow. * This segment is the superior part of the left lateral segment. Segment 2 is usually drained by this superior hepatic vein coursing laterally, and joining the left hepatic vein before the junction to the inferior vena cava. * Its portal supply is provided by a branch originating from the left main portal branch. In most cases, you can easily follow this branch from its origin. Segment 2 is separated from Segment 4A by a vertical scissura containing the left hepatic vein. * Segment 2 is separated from Segment 3 by a trans-axial scissura or transverse scissura containing the left main portal branch and from segment 1 by the ligamentum venosum.

Fortran is a general purpose programming language, mainly intended for mathematical computations in science applications (e.g. physics). Fortran is an acronym for FORmula TRANslation, and was originally capitalized as FORTRAN. However, following the current trend to only capitalize the first letter in acronyms, we will call it Fortran. Fortran was the first high-level programming language. The work on Fortran started in the 1950's at IBM and there have been many versions since. By convention, a Fortran version is denoted by the last two digits of the year the standard was proposed. Thus we have Fortran 66, Fortran 77 and Fortran 90 (95). The most common Fortran version today is still Fortran 77, although Fortran 90 is growing in popularity. Fortran 95 is a revised version of Fortran 90 which is expected to be......

Bakery Segment

...Bakery segment, led by biscuits, pegged to grow to $7.6 billion by '15 The Indian bakery industry - led by the biscuit segment - is poised to grow to $7.6 billion by 2015. This year, the sector’s growth is estimated to remain between 15 and 17 per cent, which is two points more than last year’s growth. The bakery sector has witnessed growth in both the urban and rural areas. Britannia Industries Ltd, Parle Products Ltd, ITC Foods Ltd, Surya Food and Agro Ltd (Priyagold) and Modern Food Industries India Ltd are the key players. However, medium-sized players are trying to capture a market share as well. J N Kushwaha, president, Society of Bakers, said, ‘While biscuits have a 60 per cent share of the market, bread accounts for the remainder. Fancy bakery items have a 10-15% share.’ He pointed out that in the rural areas, biscuits were growing very fast, whereas in cities, the role of bread was changing. He added that this was visible in the eating habits, and the basic reason for growth was acceptability amongst both the rural and urban masses. ‘Now, baked products are playing a vital role in people’s diet from breakfast to dinner. Items like pizzas and burgers have replaced regular items eaten at lunch and dinner,’ Kushwaha stated. ‘Earlier, people consumed only white bread. But today, apart from plain bread, there are several varieties in breads available, and every hotel and restaurant is now establishing a bakery facility to woo the consumers,’ he added....

Bow and Arrow Parabola

...arrow is 50 feet from where it was released. The target is 120 feet away and the center of the bulls eye is exactly 3 feet above the ground, and 4 inches in diameter. Assuming that Cool guy shoots a perfectly straight shot, will he hit a bulls eye? We need to use the vertex form of the equation y = a(x – h)^2 + k  To find the vertical height of the arrow as it approaches the target.  Since the arrow has a maximum height of 5feet when it has traveled 50 feet toward the target, we know that the vertex is at (50, 5).  Substituting this into the equation, we get: y = a(x – 50)^2 + 5 To find the stretching factor, a, we need to plug in a point other than the vertex.  Since the arrow was initially launched at a height of 3 feet, the parabola goes through the point (0,3).  Replacing x and y in the equation, we get: 3 = a(0 – 50)^2 + 5 3 = 2500a + 5 -2 = 2500a a = -0.0008 This gives a final equation of  y = -0.0008(x – 50)^2 + 5 We can find the height of the arrow when it hits the target by plugging in 120 feet in for x. y = -0.0008(120 – 50)^2 + 5 y = 4.888 feet The bulls eye is at 3 feet above the ground. Subtracting the height from 3, we will find the place on the target that the arrow hits. 3 – 4.888 = -1.888 feet below the bulls eye -1.888 ft * 12 in/ft = 22.656 inches below the bulls eye Cool guy missed the bulls eye. In fact he missed the whole target. Maybe next time, Cool Guy....

...layout varies from company to company, a marketing plan usually contains the sections described in Chapter 2. Smaller businesses may create shorter or less formal marketing plans, whereas corporations generally require highly structured marketing plans. To guide implementation effectively, every part of the plan must be described in considerable detail. Sometimes a company will post its marketing plan on an internal Web site so managers and employees in different locations can consult specific sections and collaborate on additions or changes. The Role of Research To develop innovative products, successful strategies, and action programs, marketers need up-todate information about the environment, the competition, and the selected market segments. Often, analysis of internal data is the starting point for assessing the current marketing situation, supplemented by marketing intelligence and research investigating the overall market, the competition, key issues, threats, and opportunities. As the plan is put into effect, marketers use research to measure progress toward objectives and to identify areas for improvement if results fall short of projections. Finally, marketing research helps marketers learn more about their customers’ requirements, expectations, perceptions, satisfaction, and loyalty. This deeper understanding provides a foundation for building competitive advantage through well-informed segmenting, targeting, and positioning decisions. Thus, the marketing plan......

...cluster analysis routines. Market segmentation is a much broader concept, however, and pervades the practice of business throughout the world. What is market segmentation? At its most basic level, the term “market segmentation” refers to subdividing a market along some commonality, similarity, or kinship. That is, the members of a market segment share something in common. The purpose of segmentation is the concentration of marketing energy and force on the subdivision (or the market segment) to gain a competitive advantage within the segment. It’s analogous to the military principle of “concentration of force” to overwhelm an enemy. Concentration of marketing energy (or force) is the essence of all marketing strategy, and market segmentation is the conceptual tool to help achieve this focus. Before discussing psychographic or lifestyle segmentation (which is what most of us mean when using the term “segmentation”), let’s review other types of market segmentation. Our focus is on consumer markets rather than business markets. Geographic Segmentation This is perhaps the most common form of market segmentation, wherein companies segment the market by attacking a restricted geographic area. For example, corporations may choose to market their brands in certain countries, but not in others. A brand could be sold only in one market, one state, or one region of the United States. Many restaurant chains focus on a limited geographic area to achieve concentration of force.......

Define the four major steps in designing a customer-driven marketing strategy: market segmentation, market targeting, differentiation, and positioning 2. List and discuss the major bases for segmenting consumer and business markets 3. Explain how companies identify attractive market segments and choose a market targeting strategy 4. Discuss how companies differentiate and position their products for maximum competitive advantage in the marketplace. Most companies have moved away from mass marketing and toward target marketing—identifying market segments, selecting one or more of them, and developing products and marketing programs tailored to each. Figure 7.1 (pg.216) shows the four major steps in designing a customer-driven marketing strategy. Market segmentation involves dividing a market into smaller groups of buyers with distinct needs, characteristics, or behaviors that might require separate marketing strategies or mixes. Market targeting (or targeting) consists of evaluating each market segment’s attractiveness and selecting one or more market segments to enter. Differentiation involves actually differentiating the firm’s market offering to create superior customer value. Positioning consists of arranging for a market offering to occupy a clear, distinctive, and desirable place relative to competing products in the minds of target consumers.

...Parábola, según su sentido griego, el termino parábole, sugiere una comparación, es decir, para significa al lado y bole echar. Este sentido comparativo aparece en los tres evangelios sinópticos sin embargo Juan utiliza otro termino, paroimia, es esta palabra también para significa al lado, pero oimai se traduce por suponer, figurar, pensar, y tradicionalmente se ha traducido en Reina Valera 1960 por alegoría y en Reina Valera Actualizada por figura. Se puede decir que según su sentido griego una parábola es lenguaje figurado que provoca una comparación con el fin de aclarar o iluminar una cosa o idea. A la hora de leer las parábolas se deben tener en cuenta tres cosas. La Historia fijándonos en el contexto histórico y social del momento. Procurando ver la parábola dentro del marco cultural del pueblo de Palestina en los tiempos de Jesús, sobre todo los modos y costumbres. Literaria viendo la parábola como una creación literaria que respeta las normas de composición literaria en cuanto a narrativa, alegoría, retórica, etc. sin caer en una lectura de las parábolas como tratados doctrinales de teología. Finalmente Hermenéutica intenta interpretar la parábola de forma correcta y aplicarla a nuestra realidad hoy. Por esto se puede considerar que las parábolas nos hablan de la intervención de Dios en la historia. Nos retan a dar una respuesta en arrepentimiento y fe, nos invitan a buscar el reino de Dios, por eso dicen que son evangelisticas. Las parábolas de Jesús son......
