INTRODUCTION
World is a storehouse of energy. And according to energy conversion law, energy neither be created nor be destroyed but can be transformed from one form to another. But we are wasting resources that can produce energy as if they are limited. Humans are able to generate approximately 150W of power while riding bicycle. However, this power goes waste without any use. If this is making use of this energy, would be able to power many electronic devices. A dynamo or an alternator can be used for harvesting the energy generated by a cycle rider while riding. We can charge mobile phones or a small lighting device with the power. Not only in bicycle but also in alternator bikes, cars and exercise bikes use this principle. Bicycle generators are mini-power stations, that allow you to convert human effort into electricity. They have been around since at least the early 1900s, when they used during WWI to power field radio equipment. A bicycle generator can be a very efficient, inexpensive and easy to construct.
Portable charger are used to charge electronic devices, almost all electronic device user’s have a portable charger. Portable charger is like a portable battery you can plug your phone in, to charge it when you don’t have access to an electrical outlet or USB port on computer.In this research I will use a regular bicycle to be the power source in a portable charger for the use to charge a cellular phone.

BACKGROUND OF STUDY

RESEARCH OBJECTIVE
The aim of this research is to make a prototype of a cellular phone whose power source is a regular dc generator. The main target of this research are the cyclist who uses their phone/smartphone while they are cycling offroad. Current smartphone offer a variety of utilities to cyclists including; GPS, maps, bicycling apps which display speedometer, phone camera and video. These utilities are important to the cyclist but of course only if the phone remains charged. This research will show how to charge phone using a bicycle.

STATEMENT OF PROBLEM
This research sought to answer the following questions:
1. How to generate power using bicycle?
2. Is the generated voltage efficient to charge your phone?

Data collection is commonly performed with surveys, questionnaires, standardized tests, or other direct observation instruments. The time limitation within the course does not permit a full descriptive study to be conducted. Rather than developing instruments and collecting actual data (which should not be done), each student will utilize data and findings from related published studies to establish what currently exists for a given phenomenon. The study will culminate in the preparation of a research paper suitable for publication. Each student will investigate and identify a journal that would be appropriate for their research paper topic.

Assignment 3

...Assignment 3 Name: Mikaela Carender Assignment 3 is a structured assignment. You must complete the questions in order. This is a short capstone assignment that will take us briefly through the research process. Let’s pretend that we’re all taking an ENGL 1001 class this semester and that we are required to write a paper on a current event, issue, or controversy. As part of our research for the paper, we are required to complete an annotated bibliography. An annotated bibliography is a list of citations to books, articles, and documents. Each citation is followed by a brief (usually about 150 words) descriptive and evaluative paragraph, the annotation. The purpose of the annotation is to inform the reader of the relevance, accuracy, and quality of the sources cited. Our instructor has informed us that we need to use 6 total sources for our annotated bibliography: * 3 must be scholarly journal articles * 3 can be a mix of popular articles, reference sources, internet sources, images, statistical sources, etc. * The information must be current, and must not have publication dates or cover dates before the year 2000 * You must cite articles in the APA style. We know that the first thing we should do as researchers is look up the topic in a reference source to gain a bit of knowledge about the topic, become familiar with the vocabulary used to write about and discuss the topic, and to start noting the cited references included in entries that will lead us to...

The Current State - Is the Catalog Relevant?

...The current state - is the catalog relevant? Today, the online library catalog is in a state of crisis. The current challenges facing the catalog are numerous. There is the challenge of having to catalog ever-increasing inputs; more print titles and online resources exist today than ever before. The high cost of cataloging is a factor as well. "In 2004, [American research] libraries spent an estimated $239 million on technical services labor alone." (Calhoun, 11) But the biggest challenge to cataloging today is competition from other services. (Danskin, 2) The Catalog began life as an inventory control tool for the sum total of our collective knowledge. Before the internet, the library catalog was the starting point for research. Now, however, the catalog is becoming less and less relevant to scholars and other library users. The OCLC Report of 2005 found evidence that “89% of college students began their searches on the web, with only 2% starting at the library website.” (Calhoun, 37) In May 1999, at the Medical Library Association's annual meeting, Dick Miller discussed the "frustrations that we encounter regularly at Lane Medial Library, in trying to cope with proliferating digital resources. With burgeoning web development, we [Lane Medical Library] felt that our 'library information' was under-utilized due to its segregation from mainstream web resources, and in danger of becoming marginalized." (Miller,1) What Miller feared in 1999, the under-utilization of...

Mp3 Players in the Classroom

...Mp3 Players In the Classroom By: Angel Larson, Jessica Gallo, Ashley Dorzok and Michael McClanathan We questioned if MP3 players should be available to students at Moraine Park Technical College. If so, would they improve productivity and student morale? Since many students already use their MP3 players when doing homework and/or listening to reading material for school, we believe the chances for MP3 players being used will continue to grow. Should college students at Moraine Park Technical College be awarded a MP3/iPod player to use throughout their educational career? Would having the ability to download audio books, learning materials, and/or podcasts enhance students’ learning, or become a distraction and hinder it? The purpose of our research is to decide if MP3 Players should be available to Moraine Park Students and whether it will improve productivity and student morale. Variables used will include resources and a survey given to our demographic. Our hypothesis is that productivity will increase greatly if iPod’s/MP3 Players were provided to students at Moraine Park Technical Colleges. These devices can be used to store books, lecture notes, and class videos. They are portable; making it easy to carry in a backpack, purse and often times, pockets. Students and Instructors can take advantage of these devices by uploading appropriate lesson plans and study guides to their MP3 players. While music and audio books enhance concentration, we believe...

November 24, 2014 Section Two: Executive Summary: We all want a family dog whether we are single or have a full size family but are we all really ready for all that it takes. Dogs are beautiful creatures who show you unconditional love even when you don’t want it, they can make you smile, and they can relax you when you are down and stressed Most dog’s become your protector, a part of your family, unconditional companionship. Dogs are great but if you are not prepared for the commitment of one, then maybe you aren’t ready. A dog has to be fed at least twice a day, sometimes special food depending on the breed of dog you get. They must have access to water 24 hours a day which sometimes can be difficult when you have small children. They take obedience, they take 10-15 years of your life of taking them out to use the restroom, expenses for food, grooming &vet visits. You must play with them, exercise them and accept their companionship. Dogs are not tiny humans who grow up to be self-sufficient, they will always rely on you and want you to take care of them and have their best interest at heart. They are not furniture that you can buy and when you decide that you just don’t have the time or space for such a demanding animal that you could just take them back.
