El calibre, también denominado cartabón de corredera o pie de rey, es un instrumento para medir dimensiones de objetos relativamente pequeños, desde centímetros hasta fracciones de milímetros (1/10 de milímetro, 1/20 de milímetro, 1/50 de milímetro). En la escala de las pulgadas tiene divisiones equivalentes a 1/16 de pulgada y en su nonio de 1/128 de pulgadas. El inventor de este instrumento fue el matemático francés Pierre Vernier (1580 - 1637 ), y la escala secundaria de un calibre destinada a apreciar fracciones de la unidad menor, se la conoce con el nombre de Vernier en honor a su inventor. En castellano se utiliza con frecuencia la voz nonio para definir esa escala. Consta de una "regla" con una escuadra en un extremo, sobre la cual desliza otra destinada a indicar la medida en una escala. Permite apreciar longitudes de 1/10, 1/20 y 1/50 milímetro utilizando el nonio. Mediante piezas especiales en la parte superior y en su...

...areapplying for the open position, 26 are female and 26 are male. If the company assume that each of the 52 possibilities is equally likely, it is reasonable to expect that the company would select a male applicant that is qualified for the open position 0.50 of the time of a period of time ( 26/52 = ½ = 0.50 ). This illustrates the basic rule for obtaining probabilities in situations in which each of the possible outcomes is equally likely, the probability of the occurrence of an event is equal to the proportion of the possible outcomes characterized by the event. In the case of hiring a qualified male employee, 26, or 0.50, of the 52 possible outcomes will be characterized by the event “a qualified male employee.” Tradeoffs in accuracy and precision Conclusion References Duan, Li. “The uncertainity sensitivity index method (USIM) and its extension’, Naval Research Logistics, 1988.

Basically, it will describe some of the current trends in the business communication. In addition, it will go into some details about what role does business communication play in your day-to-day work activities, how it helps you manage your daily activities, trends that I have encountered at my current workplace, and what message type are results of these trends. The roles that communication plays in my day-to-day activities are vital because I have to be on point all the time and have to be very careful of how I communicate verbally. In other words, I have to make sure I do not say words that will associate me with terrorism because of pass incidents both companies that I work for are very strict on this. In addition, I have to make sure that my selected words do not indicate racism, discrimination, or stereotyping of any sort. One of my responsibilities is to respond to requests that are made using radio (CBs) or phones. In doing so, I have to be very professional in my verbal communications (responses) using proper grammar when speaking because everyone is listening including all managers.

...to Measure Costs Less Accurately to Improve Decision Making,” it shows that certain cost systems are less accurate, and more advantageous, than cost technology. The companies use biases and imprecision that is legal, improves decision making, and influences behavior positively. Upwardly biased costs are one example of this. Firms that face competitive pricing overstate product cost in order to cover variable costs. From here, a firm is able to offer discounts without going below production cost. Another example is downwardly biased costs. Firms will use the rationale of “target costing” to set the product price at what it should be. These targets cause innovation and improvement since they are so far below the current standards. Lower precision is the third accuracy cost system. It is designed to make data that not precise. The outcome of this system is that some costs are overstated and some are understated. This causes employees to focus on performance areas that managements decides is important, and causes continuous improvement and competitive advantage. Of course, using a less accurate cost system is not beneficial to all companies. For example, a company that is selling a commodity does not need to worry about having too much competition and would not benefit from use inaccurate data. The less accurate cost system strategies are used by management to implement competitive strategies, not develop them. The choice to use a less accurate cost system should be made to help...

...There are so many different ways to approach this, it almost becomes an art. If there was a button that could easily and accurately give us the portion of overhead to associate to each cost pool this process would be much easier. The nature of ABC model is to allow different approaches; time model equations are always different. There are different ways to solve for the same cost driver. The best way to be accurate is to try and isolate activities down to the component drivers. For instance, with deliveries we can further break that out into deliveries for desktop service and commercial delivery. Now if with commercial deliveries, if the cost was driven by expedites or overnight orders then ideally we would account for those. The further detail we try and obtain the more complex our overall method becomes. To combat these complexities and still seek detail we can lean on technological developments in software that can aid in these efforts. Overall, this case left out a lot of details such as total number of orders and better detail on acquisition cost. We could have obtained more accuracy if we had more details around current expenses and orders. For a simple company such as a paper distributor, I would have not anticipated such complexity in calculating cost. This assignment took a long time, but I have a much deeper appreciation for calculating accurate cost. Order entry personnel spend a disproportionate amount of time with manual orders which is driving up cost. Customers...

...Accuracy and Precision CHM/110 Accuracy and Precision Accuracy and precision are used for measurements. The term accuracy means to have the exact value. The term precision means to be comprehensive and exact. The accuracy of a value is the measure of how closely the results agree with a true or accepted value. Precision of a value is the measurement of the reliability of the experiment. I never thought that almost everything we do in our everyday lives could be considered using chemistry. The first example is gasoline, especially considering the price of gas now. If someone is advertising $4.05/gallon but their pump is really charging that much for every 4/5 of a gallon, the pump is precise because it keeps charging the same for everyone but it would not be accurate. The second example is medications; medications have to be extremely accurate measurements. When the doctor gives a certain medication they are assuming a level of accuracy from the medication. If it is inaccurate a person can die from taking that dose. Therefore if medication is precise but not accurate that could mean anything. A pharmaceutical company can be precise in producing pills with the same dosage, but if that dosage isn't accurate than it could kill someone. The third example is baking; when you're making a ton of cookies for a fundraiser or something and so you start making batch after batch of cookies. However, it isn't until the 8th batch that you realize you've been using the tablespoon to...

...science accuracy is the form of measurement that calculates the degree of closeness of a quality to its true value. Precision is a unit of measurement that is also referred as the ability to reproduce the same results multiple times” (Taylor, 1997). The differences are within the definitions, it all depends on what you are looking for within the results of a test for the proper use of these two units of measurements. Society depends on the accuracy and precision of measurements for products sold by the retail industry, such as a gallon of gasoline, a bushel of corn, or a liter of bottled water. These measurements have to be precise and accurate when it this relates to how farmers sell their products such as wheat, corn, milk, peanuts, and cotton, by weight and or in a bulk sale. Like food products gasoline, water, oil, and several other liquid goods are sold in quantity and if the measurements are not accurately sold per gallon then the United States government will not retain a profit from the barrel of gasoline, water, oil, and several other liquid goods that are purchased from other countries. I would have to say that this really is about supply and demand and the ability to generate a profit from the accuracy and precision of the weight and how much to sell an item for in most situations. Other ways society depends on the accuracy and precision of measurements is within the food industry. If a chef ordered 500 pounds of potatoes because 500 pounds of potatoes...

...Performance Appraisal Before I start with my paper about performance appraisal, I would like to give you a definition of it and describe it a little bit. In the text book it defines performance appraisal as a process, typically delivered annually by a supervisor to a subordinate, designed to help employees understand their roles, objectives, expectations and performance success. This would help employee’s build more team work, continuous improvement, learning, and motivation for their job. But as we all know there are disadvantage to this program because people would start finding ways to get around it. For example, my job has this program and it became a little hostile. The first aspect that selected for this paper is strategic relevance. In the textbook strategic relevance refers to the extent to which standards relate to the strategic objectives of the organization. For example, my job is like General motors and whirlpool. They do keep metrics of performance. My job as at least 2 people on each cell and we have tons of metric, and we evaluate it every day. I have a metric that I have to keep track of and this count towards the employee. We have metrics of their hourly production, their total for the day, and out of the box failure. We do hold the employee responsible for all the failures and mistakes. This does affect their performance appraisals. The draw back to that in my company is that there are more than one people working in the cell and how do we know who is...
