Project of using the wireless sensor network (WSN) Essay Example for Free

Project of using the wireless sensor network (WSN) Essay In the previous era, the technology application mostly using wire but now a wireless device has become commonplace. The definition of the wireless sensor network is an application that having no wires connection on that devices. In addition, to make the system easy to monitor from a distant location, the RF 433MHz module was used. So, this project gave rise to the idea for studying details about the RF 433MHz module performance for WSN application. Project Background Nowadays, using the wireless sensor network (WSN) technology to monitor the environment helps someone to solve the problems of deployment difficulty, high cost, and realized unmanned monitoring which is mostly used in the factory, buildings, laboratory, and house. This project is to study the range and performance of the RF 433MHz module for WSN application. RF 433MHz module is popularly used in the remote control system. This range also available to use in this area. There are two types of the RF module which is transmitter and receiver. From research, using this module, the data can get more accurate and detailed information than another transmission for the wireless sensor network. The range that can reach by this RF module is different between outside and inside area. For inside area, it can work for 50 meters through multiple walls with an antenna, while for the outside area, it will be able for hundreds of meters. Besides that, a microcontroller such as Arduino also used in this project. Arduino that available for this project is Arduino PRO which is it has 3.3V port that will be easier to connect directly to the transmitter of RF 433MHz module. This project also about to study the analysis of the data transmission by giving a few of distance between the transmitter and receiver of the RF 433MHz modules when located in the obstacles or line of sight area. Then, the data that are received will be displayed on the Liquid Crystal Display (LCD), whether there are data losses or not. Problem Statement The problem that becoming as issues right now is there is a lot of ways to send data but the problem is about the range, cost, and data losses. So, for this situation, study the performance of RF 433MHz can overcome the problem for the WSN application.

Case 17 ? Johnson & Johnson :: essays research papers

Case 17 – Johnson & Johnson 1. Diversity should provide greater alternatives and inputs into the decision process, but if diversity is blocked due to organizational infrastructures that do not allow the free flow of information, than the diversity goes unutilized. Johnson & Johnson (J&J) structured its company to insure the positive impact of diversity in regards to decision making through its creation of FrameworkS. Through Frameworks, the executive committee is partnered with a variety of managers from around the organization that concentrate on specific, unprogrammed organizational decisions. FrameworkS matches the problem with appropriate decision making method. In this approach, managers share the problem with others and engage the group in consensus to arrive at a final decision. By incorporating managers from around the organization, FrameworkS provides a process that successfully incorporates knowledge from a wide variety of sources. Managers are able to bring a variety of perspectives and experiences to deal with the problem at hand. The knowledge brought into focus is greater with these additional individuals involved. In addition, difficulties including decision biases (confirmation traps and hindsight traps) and escalation of commitment can be countered in a constructive manner. J&J provides an environment that supports information search and open discussion among members of the group. By challenging long-held assumptions, a better decision develops from the interaction of group members. 2. J&J wished to increase both the number and quality of strategic choices for creating its future. Groups are often more successful than individuals in developing creative solutions due to the increased diversity of ideas available to the members. J&J managers attempted to benchmark high performance activities by investigating processes at its three internal and three external organizations. With a focus of identifying and implementing the new processes into J&J, the program "What's New" was the focus of the collection of J&J’s executive and senior management team. By mixing managers from different organizations within J&J, the executive board hoped to manage knowledge in a manner that supports new ideas. A manager from one area may be able to shed considerable insight into the problems of a manager from another section of the company and as a result, organizational learning is increased through a free exchange of ideas. 3. J&J has shown through its Credo and actions that the company is very committed to ethical behavior on the part of its employees and managers. Its reaction to the Tylenol poisoning, with its emphasis on socially responsible behavior above immediate profits, was entirely consistent with its ethical code of placing the customer first and shareholder interests second.

Electronic books verses paper book Essay

Reading is a big part of our lives, whether you are reading for work, school or pleasure, books, newspapers or magazines, it is something that most people do on a daily basis. Today, there are different ways you can read: either electronically or by paper. Electronic devices are starting to run our lives, by getting an e-book or e-reader (kindle, nook, iPad, etc†¦) reading could change for the average reader. Electronic readers are better than paper books. Having an electronic reader can be very convenient. You can rent or buy books, magazines, and newspapers for free from virtual libraries similar to the way you would from your local public library. There are a lot more books available through the virtual library. Since it is a virtual library, you are using Wi-Fi and you can instantly receive your reading material electronically. Usually when you rent a book from the virtual library, you can have it for as long as you like, but are limited to one book month. However, it is quicker than getting in your car and driving to the library or store to get a book. â€Å"The convenience of downloads saves transportation costs and reduces carbon emissions from book distribution and consumer travel to and from bookstores. † (Maxwell & Miller, 2013, para. 4). Loaning books to family or friends is a bit easier with having the psychical book to give. Yet, some devices may allow you to share downloaded books with others. All things are faulty in life. â€Å"As convenient as the use of different e-readers can be, technology isn’t always reliable. † (Taylor, 2013, para.4). Since e-readers are an electronic device, you have to charge the battery; however, it can last for a month or two. The screen can break on e-readers just as easy as a page can tear out of a book. You can change the font size if you have difficulty reading small print and you can also adjust the screen brightness so you can read in the sunlight or in the dark. Paper books do not need to hold a charge for you to enjoy and the screen will not ever break, but pages can tear. The font size is what you get and it cannot be altered on what is already printed. It is nice to have a collection of books and you can do that with either an e-reader or paper books. With your e-reader you can carry all of your books at once and your paper books can be on display in your home. E-readers are pretty slim and light-weight, some books can almost double the weight and be bulky. For the average college student, e-readers may be better so they are not carrying a few different heavy books around campus. Electronic readers are much more diverse than paper books. There are a dictionaries built into e-readers, so you can look up a word just by highlighting it. A great feature to e-readers is it has a bookmark to save your place. Turning the page is as simple as a tap or swipe along the screen of the e-reader, whereas with a paper book or newspaper you physically flip the pages. Reading with children may be better with paper books, but tablets can be used as an e-reader and games and learning applications can be downloaded for children. â€Å"Many e-readers also offer Web browsing, games, music, movies and an endless array of apps such as The Weather Channel or Microsoft Office to enhance the user experience† (Cancio, 2011, para. 3). Children growing up today will probably be reading more things electronically at school, so getting them use to the electronic devices young can be a good thing. With technology advancing so rapidly, it can be hard to keep up with the advancements. Paper books are great if you are a book collector who wants to show off those books and if you do not mind carrying them around. In the long run, e-readers can be more convenient and cost efficient because of the discount on the books being electronic instead of printed. If you enjoy reading while traveling, lying in bed, and want to have a large selection of books to choose from and receive them quickly, e-readers are the better option for you.

U.s. Defense Of Homeland Security - 3756 Words

After 9/11, the United States completely revamped its entire system of defense, policy prescription and stance with regards to terrorism; both foreign and domestic. The Department of Homeland Security was created, direct militaristic action was taken against these terrorists and domestic and foreign policy was changed in order to combat the new threat. While much of this â€Å"war on terror† was fought far away from U.S. soil, that did not stop these new policies from affecting the lives of U.S. citizens directly. The most noticeable, controversial and powerful of these policies was the U.S.A. PATRIOT Act (Breinholt, 23-25). While the PATRIOT Act has drawn the ire of many U.S. citizens due to its far reaching effects, lack of jurisdictional or†¦show more content†¦This paper will argue that not only has the PATRIOT Act been successful in its goal of stopping and deterring terrorism, but that it will continue to do so as it continues to evolve in the future. First, a s hort overview of the PATRIOT ACT is necessary, briefly describing what each of the ten titles in the USA PATRIOT Act is intended to do. During the Overview, this paper will emphasize the importance of specific Titles that directly halt or deter specific terrorist acts, as well as their methods of operation. Second, American citizen complaints and direct violations to the constitution will be noted as well as if and when those violations have been rectified within the act after revisions. Afterwards, previous and ongoing issues and concerns will be explained and assessed. Finally, the Act’s overall success and future policy prescriptions for continued success will be laid out. Title I of the PATRIOT Act contains six sections and establishes funding for counterterrorist measures within the United States Treasury, establishes powers provided to the executive office and basically lays the groundwork for battling the threat of terrorism at home. It establishes and provides funds t o specific agencies such as the FBI, prevents discrimination against Arab Americans, allows networking surveillance by the director of the Secret Service in order to prevent terrorist attacks (USA PATRIOT Act Section 105). The final section of this Title of the
