...Unit 2: International Measures and Conversions Objective: At the end of this chapter, the reader should be able to: * Define measurement systems * Define metric system * Convert values from metric to metric system * Convert values from metric to American system and vice – versa. * Convert temperature values. 2.1. Introduction: International Standards for measures and conversions were felt as a need, as the international trade between the nations started to increase. With the increase of the trade, the disputes between the buying and selling nations started increasing, as these nations employed different standards of measures. The interpretations of the business contracts varied from nation to nation and this factor started hurting the international trade. Hence to counter the fact that the weights and measures are different in different countries, a set of internationally accepted standards for measures and conversions were needed. The international standards should be enough to give single guidelines for the measures and conversions as well as reduce any points of conflicts. To reduce the points of conflicts the international trading community moved on to the metric system of measures and conversions. In the modern times the measurement and conversions have also been in use. 2.2. Measurement Systems: We can define “Measurement” as a set of integers assigned to a characteristic of an object or an event, which should create a system that...

...Unit Conversion Workshop and Homework Assignment DUE Tuesday, October 4th Name_________________ The purpose of this workshop and homework assignment is for you to become comfortable converting between different units of measurement, a skill necessary to all forensic scientists. Many publications in the United States still use the English system, whereas many scientists use the metric system. Therefore, it is often necessary to convert between the two systems. Feel free to work in groups on this assignment, but each student should turn in a copy. SHOW YOUR WORK!!!! Length 1) It is useful to be able to estimate lengths in the metric system. Examine a ruler, and get an idea of the length of a millimeter, centimeter, and meter. |Common Units of Length |Abbreviation |Meter Equivalent | |Millimeter |mm |1000 mm = 1 m | |Centimeter |cm |100 cm = 1 m | |Decimeter |dm |10 dm = 1 m | |Meter |m |1 m | |Kilometer ...

...UNITS AND UNIT ANALYSIS Introduction Quantitative physical properties are recorded as a number with a unit where the unit indicates what instrument was used. In this country, the most common system of units is the English System but in science, the preferred system is the Metric System (SI). The SI system is preferred because all units that are proportional to some basic unit are given in terms of powers of ten of the basic unit. In this chapter, the units for length, mass, temperature, amount and time in both systems are given as well as some compound units. Changing from one unit to another is referred to as unit analysis problems and these are developed along with the introduction of the units. This is preceded by a general strategy for solving unit analysis problems. General Aspects of Unit Analysis Problems In either system, there are many units for the same quantitative property. For example, in the English system length can be given in inches, feet, yards or miles. Having different units for the same property may seem objectionable but consider the following. Suppose that the only unit for length was the inch and you are traveling from Waco to Dallas. When leaving Waco you see a sign that said Dallas 5700000 or Dallas 5.7x106 inches being understood. The problem is that very large (or very small) numbers are difficult to interpret. Just how far is 5700000 inches and how long will it take. In actuality, the sign reads Dallas 90 mi....

...Unit 1 When we manipulate expressions and equations, we realize that there are basic properties that govern what we can and can't do. One of those properties is the Commutative Property. Let's consider this property in our discussion. Is there a commutative property of subtraction? In other words, does order matter when subtracting? Why or Why not? Please provide an example to explain your reasoning. Please share any trick or mnemonic device to help you recall what this property is or how to use it. There is no Commutative Property in subtraction. Yes order does matter subtracting, you can not subtract a larger number from a smaller number, such as: 3-6 = this subtraction can not be done but if you turn it around and subtract the smaller number from the larger number it will work: 6 -3 = 3. In all the properties you can not use subtraction or division, just addition and multiplication. Unit 2 As we know, a set is just a collection of objects that are similar in some way, like a gaggle of geese, pride of lions, or an army of ants. To further classify our world, we can create subsets from a larger set. Let's consider the idea of a subset for our discussion. • Give an example of a subset and a proper subset. Explain the difference between a subset and proper subset. • Can any set be a proper subset of itself? Give an example of why or why not. A = {Lions, Tigers, Jaguar} B={Lions, Tigers, Leopard, Cheetah, Jaguar} *Everything that is in A is in set B therefore it...

...paper, the learning curve will be defined, discuss the alternative approach, and discus total quality management (TQM) approach to continuously improve the processes set forth in the Mario’s Pizzeria Simulation. The learning curve is “a line displaying the relationship between unit production time and the cumulative number of units produced” (Chase, Jacobs, & Aquilano, 2006, p.134). This means there is a decrease in the time to produce a unit as the number of units produced increases. It is based on three assumptions: “1. The amount of time required to complete a given task or unit of a product will be less each time the task is undertaken, 2. the unit time will decrease at a decreasing rate, and 3. the reduction in time will follow a predictable pattern” (Chase, Jacobs, & Aquilano, 2006, p.134). The efficiency of the service provided after a change is made will improve as the service is repeated. Mario’s Pizzeria’s metrics to gauge the efficiency of the restaurant is the percent utilization of the two-person tables, four-person tables, wait staff, kitchen staff, ovens; average wait time; average queue length; number of two and four person group who balked and were served; and lost sales. These metrics shown in Table 1 shows how the changes made in the...

...buying new equipment within a Shanghai facility, or option three outsourcing the production to another vendor in China. My strategic recommendation would be to minimize cost so the solution in which cost is concretely minimized would depend on the factor of how many units are needed for this initial production. Utilizing the breakeven cost volume analysis tool, if 25 to 80 units are needed for production, the lowest cost option is option 1 which is $75,000 dollars. If preparing 80 to 300 units, the lowest cost option is option 2 which yields a cost of $240,000 dollars. Lastly, utilizing any amount of units over 300, yields the lowest cost, option 3, as $350,000 dollars. A1. Manufacturing Recommendation: Output Table 2: Breakeven points Crossover graph A1a. Manufacturing Recommendation: Explanation I would prefer to minimize cost so the solution in which cost is minimized would mostly depend on how many units are needed for production. My sincerest recommendation would be to employ option 1, which is reconditioning the existing equipment, if planning involves producing 25-80. If the plan changes to accommodate the highly anticipated demand of the samba sneakers, I would prefer to produce greater than 300 units utilizing option 3 which is an outsourcing to the third party vendor within China.

Don’t simply copy from the organization’s mission statement. I chose to use WalMart for this assignment; WalMart’s primary mission is to bring consumers high quality goods at a low, discounted price. Sam Walton’s original vision was to accomplish this; although WalMart has grown substantially since its initial founding, this mission has not changed. WalMart employs just over 2 million people worldwide and has 8,970 locations. Q#2 From your research of the organization, identify a single Business Process Change that the organization will need to contemplate and undertake in the coming year.

You may download, copy and distribute it as you wish. . . if you find it to be of any value. It can be gotten from the URL: http://iweb.tntech.edu/murdock/books/PreSci.pdf so you will need the (equally free) Adobe Acrobat Reader to view it and print it. This piece of software is on many institutional computer systems, and if you don’t have it on your machine, go get it at http://w1000.mv.us.adobe.com/products/acrobat/readstep2.html The pages are in a format which looks best when printed double-sided. I’m giving it away to anyone in the same situation as me: You have many students in your introductory science courses who don’t have adequate preparation in basic mathematics, and you want to give them something simple and friendly to read. Preferably something that gets right to the point and which costs no more than the paper it’s printed on. I didn’t know where I could get a document like this, so I wrote one. You’ll notice that “significant figures” have not been rigidly observed in the numerical examples. That’s because this book is directed at students who need help in getting any correct numbers to round off. If you find this booklet to be useful or else worth exactly what it costs and/or have any suggestions, please write to me at murdock@tntech.edu To the Students: Your college science courses may very well require you to do some mathematics (algebra...

...Patient Flow Metrics Paper Southern New Hampshire University HCM - 500 INTRODUCTION Emergency Rooms and the waiting rooms associated to these emergency rooms are subject to many conversations of inefficiency. Dealing with these inefficiencies are two massive challenges that are facing the healthcare industry today. The wait times and dissatisfactions associated with going to a emergency room, definitely need to be curbed and addressed. Even when the system has patient flow that is simplified with pre determined appointments, and served by a single doctor there are various factors that are related to inefficiency. This flow does get a lot more complication with walk ins 24 hours a day in an emergency room setting. There are also no single doctor that serve the patient and there are no pre determined processing times. Doctors generally are rotated, while at work are constantly interrupted due to the nature of the emergency, and related to to other medical consultation. EHR (Electronic Health Records) are being installed and implemented in a number of hospitals and healthcare units, to achieve the goal of improving the quality and decreasing the costs.National benchmarking for quality in the ED setting places significant focus on timeliness, safety and efficiency standards, most directly reported as overall length of stay (LOS), door to doctor times and left without being seen, using them as proxies for quality measures that are difficult to collect, such as time to analgesia...
