...LM2907/LM2917 Frequency to Voltage Converter June 2000 LM2907/LM2917 Frequency to Voltage Converter General Description The LM2907, LM2917 series are monolithic frequency to voltage converters with a high gain op amp/comparator designed to operate a relay, lamp, or other load when the input frequency reaches or exceeds a selected rate. The tachometer uses a charge pump technique and offers frequency doubling for low ripple, full input protection in two versions (LM2907-8, LM2917-8) and its output swings to ground for a zero frequency input. The op amp/comparator is fully compatible with the tachometer and has a floating transistor as its output. This feature allows either a ground or supply referred load of up to 50 mA. The collector may be taken above VCC up to a maximum VCE of 28V. The two basic configurations offered include an 8-pin device with a ground referenced tachometer input and an internal connection between the tachometer output and the op amp non-inverting input. This version is well suited for single speed or frequency switching or fully buffered frequency to voltage conversion applications. The more versatile configurations provide differential tachometer input and uncommitted op amp inputs. With this version the tachometer input may be floated and the op amp becomes suitable for active filter conditioning of the tachometer output. Both of these configurations are available with an active shunt regulator connected across the power leads. The regulator clamps...

...accelerometers, and micro-optical sensors. Micromechanical sensors and improved fiber-optic gyros are expected to replace many of the current systems using ring laser gyroscopes or mechanical sensors. The successful introduction of the new technologies is primarily driven by cost and cost projections for systems using these new technologies are presented. Externally aiding the inertial navigation system (INS) with the global positioning system (GPS) has opened up the ability to navigate a wide variety of new large-volume applications, such as guided artillery shells. These new applications are driving the need for extremely low-cost, batch-producible sensors. Index Terms—Accelerometer, gyroscope, inertial, MEMS. I. INTRODUCTION LECTROMECHANICAL inertial sensors have generally dominated guidance, navigation, and control applications since the dawn of inertial sensing in the early 1920s [1]–[4]. In recent years, however, new technologies have enabled other kinds of sensors that are challenging and have successfully challenged this dominance [4]–[6]. For example, the ring laser gyroscope, which was invented in the 1960s, replaced electromechanical instruments in many applications by the late 1980s and early 1990s. Early on, the driving force for introducing these new technologies was to improve performance and reliability. Over the last 30 years or so, the primary driving force has been to achieve...

...Over the past forty years a new growing trend has been detected. This coincides with the desire of businessman to dislocate their production and companies outside the domestic market. Such phenomenon, known as “delocalization of production”, can be defined as the social/ managerial/ organizational process through which firms not only deploy their sales on foreign markets, but they also draw supplies like raw materials, technology, facilities, equipment, financial resources and manpower. The aim of this paper is to provide an analysis on winning internationalization strategies, that will help a company to successfully penetrate a new market. Further on we will see a little case study on the shoes and accessories company Geox, performing an overview of its presence on international markets, providing a little historical background of the company and evaluating its competitiveness. Competition intensification on the global scale has lead an increasing number of companies, in the last decade, to seek new job opportunities on international markets. Internalization, today, is not only a way to increase the firm’s value, extends its competitive advantage and access to new opportunities. In our current economic environment it has become an useful and practically necessary way that may guarantee a firm’s outliving. Going international for a company means going through a tough and long process, that will change its assets completely and with no coming back. It involves quite...

...New Methods and Applications in Mitochondrial DNA Analysis Brandon Sanders UMUC BIOL 320 6380 Forensic Biology New Methods and Applications in Mitochondrial DNA Analysis Mitochondria are structures within cells that function as energy mediators. Each cell contains hundreds to thousands of mitochondria. We know from this class that DNA is bundled in chromosomes inside the nucleus, but mitochondria also include a very small amount of their own DNA. This genetic material is known as mitochondrial DNA or mtDNA. The use of mitochondrial DNA (mtDNA) sequence analysis to identify biological evidence has been well documented. More than 50 laboratories worldwide are now applying mtDNA analysis in forensic casework; e.g., to help identify human remains or to help discover the source of a shed hair. In addition, the number of mtDNA sequences added to population databases has grown rapidly. Estimates find that there are greater than 5000 sequences which have been generated in forensic laboratories, and that an equal number will be generated in the next year or two. As a result, more is known about the genetics of mtDNA, as well as the power of the system as a forensic marker. Therefore, the analysis of mtDNA is in a strong position as we approach the next millennium. Using Mitochondrial...

...Abstract Merging CUDA kernels is an effective method to improve the overall GPU performance. In CUDA, the kernel running on GPU can’t be suspended unless it is finished. As a result, we should co-schedule all the pending kernels to take full utilization of GPU resource. In this paper, we mainly make two contributions to the kernel co-scheduling. The former is we provide a model to predict the running time of merged kernel. According to experiments, our model predicts accurately in most situations. The latter is we put forward a new method in selecting kernels from pending list to be merged. Comparing to simply merging neighbor kernels, the co-scheduling method presented in this paper could utilize GPU resource more fully and improve the overall performance. 1. Introduction With the rapid advance in IC technology, and the bottleneck of performance improvement in traditional single processor architecture, CMP was proposed as significant approach to make better use of the increasing transistors. With its advantage in exploit of higher level parallelism in DLP, TLP, and less consumption compared with single processor architecture, Multicore processors has become the main stream architecture. However, the performance cannot always be improved by adding cores into a chip because of the memory bandwidth limit. The performance is especially bad for data-intensive programs like informatics applications. Moreover, the function of multicore processors is fixed whose...

...or overdraft, additional partners, share issue, leasing, hire purchase mortgage, trade credit and government grants. For a high-tech company, firstly, long-term sources of finance should be used. For example, owner’s investment should become the first fund of the company. Owner’s investment is money which comes from the owner’s own savings. It is the form of start up capital - used when the business is setting up, it also can be used for business expansion. Owner’s investment is a long-term source of finance and there is no interest needs to be paid. But owner’s investment is a limit to the amount because of the owner has a limited amount that can be invest. The founder should look for more money from other aspects in order to start up a new company successfully. Bank loan is a good choice for the founder. Bank loan is money borrowed at an agreed rate of interest over a set period of time. It can be regarded as the medium or long-term source of finance. Because the repayments are spread over a period of time, which is good for budgeting of company, founders for company starting up or operation usually use bank loan. A further way of raising funds that has become popular is through venture capital. Merchant banks and investment specialists may be willing to provide...

No part of this publication may be reproduced, stored in a retrieval system, or transmitted in any form or by any means, electronic, mechanical, recording or otherwise, without the prior written permission of Charles E. Cook. Manufactured in the United States of America. Preface You will find this book to be somewhat unusual. Most computer science texts will begin with a section on the history of computers and then with a flurry of definitions that are just “so many words” to the average student. My approach with Blue Pelican Java is to first give the student some experience upon which to hang the definitions that come later, and consequently, make them more meaningful. This book does have a history section in Appendix S and plenty of definitions later when the student is ready for them. If you will look at Lesson 1, you will see that we go right to work and write a program the very first day. The student will not understand several things about that first program, yet he can immediately make the computer do something useful. This work ethic is typical of the remainder of the book. Rest assured that full understanding...

As a soon-to-be college graduate, the future beckons, bright and inviting. There are endless career opportunities that await those who have put forth the effort to receive an education. The career goals toward which I am currently preparing are to become a highly sought-after piano teacher and piano-teacher trainer with a full roster of students, complete with a waiting list for those who wish to join my studio. I plan to build a fully- developed business model for my piano studio. This plan will include curricula for various ages and skill levels, as well as plans for accommodating specific needs of individual students. The plan will also have processes for the acceptance and rejection of potential students, registration and payment options, and online booking opportunities. This will be optimized through the use of technology. Technology, in all its many forms, has transformed the world we live in, and I anticipate that it will prove to be of great use to me in the development of my career goals.

...You are the news director of a local television station. The city council has just voted to close city parks 3 days a week to save money. Meanwhile, a major celebrity has died. The park story has greater effect on your viewers, but the celebrity death will get bigger ratings? Which do you make your lead story and why? o Your news organization is owned by a massive corporation that also owns an electronics company. It has learned that the refrigerators the electronics company makes are fire hazards and have destroyed several homes. How do you cover the story and how do you acknowledge that you are owned by the same corporation? o You are the chief editor of a large metropolitan daily newspaper. One of your reporters is caught fabricating sources and making up facts. How do you handle the situation, from disciplining the reporter to explaining it to your readers? . Solve the problem using what you have learned. Solutions must be realistic. If you think cable news networks do not have enough foreign coverage, for example, it is not enough to say you will simply hire more reporters. You must say where that money will come from. Be creative, both in the identification of the problem and, especially, in the solution. . Include the following: o The role of media in delivering news to the public o The significance of immediate news media delivery on culture o The social responsibilities of news media. o Ethical and legal considerations...

... If I were a news director of a local television station I would decide to make the story about the city parks being closed three days a week my lead story over the celebrity’s death. The reason behind why I would choose this one instead of the death of a celebrity. The city parks being closed three days each week will impact the locals that live near those parks. A celebrity’s death will be in the news for days to come and could become tomorrow’s lead story, but today a local story that is important to its community does not need to be over looked because of a continuing story that will be there for days to come. Local news stations have obligations to the communities that they reach. These communities look to them for what is going on and more importantly, what is happening locally. With all of the different ways to deliver local news to people, it is possible to make the lead story the celebrity’s death on the news’ website. Then possibly later in the day change it to follow the television’s schedule of delivering the news, such as changing the lead story to the city parks being closed three days a week. With technology, and the several ways of delivering the news, it is very possible to have more than one leading story across the board. In the past we, as in human beings, did not have this advantage. Newspapers from the printing presses were the main source for receiving the news, local and abroad. This...

...Researching Variable Naming Rules Visual Basic You must use a letter as the first character. You can't use a space, period (.), exclamation mark (!), or the characters @, &, $, # in the name. Name can't exceed 255 characters in length. Generally, you shouldn't use any names that are the same as the functions, statements, and methods in Visual Basic. You end up shadowing the same keywords in the language. To use an intrinsic language function, statement, or method that conflicts with an assigned name, you must explicitly identify it. Precede the intrinsic function, statement, or method name with the name of the associated type library. For example, if you have a variable called Left, you can only invoke the Left function using VBA.Left. You can't repeat names within the same level of scope. For example, you can't declare two variables named age within the same procedure. However, you can declare a private variable named age and a procedure-level variable named age within the same module. Python Must begin with a letter (a - z, A - B) or underscore (_) Other characters can be letters, numbers or _ Case Sensitive Can be any (reasonable) length There are some reserved words which you cannot use as a variable name because Python uses them for other things.- See more at: http://www.w3resource.com/python/python-variable.php#sthash.5AXuVlWN.dpuf Java Variable names are case-sensitive. A variable's name can be any legal identifier — an unlimited-length...
