I’m Afraid It Will Take Forever To Complete My Degree

Traditionally, a Bachelor’s Degree takes up to four years to complete, a Master’s Degree requires at least two years, and a Doctorate Degree can take up to eight years or more. That’s all fine and good for someone who can dedicate themselves to being a full time student, but for those who can only commit to part-time status, those timelines might appear too far offrepparttar horizon.

Butrepparttar 139018 facts ofrepparttar 139019 matter are that most degree programs at today’s career colleges are based on accelerated learning, meaning that most degrees take less time to complete than traditional learning environments. Coursework is based on shorter semesters—typically five weeks—and delivering a quality education as rapidly as possible without sacrificingrepparttar 139020 student’s ability to learn and absorbrepparttar 139021 material. In some cases you can even earn your degree is less than a year!

I’m Afraid That Employers Won’t Take My Degree Seriously

Because their degree won’t be coming from some top-name university like Harvard or Yale, some would-be students decide that it’s not worth getting a degree from a school that employer’s won’t view as credible.

In reality, however, most employers today do view degrees from career colleges as not only credible, but oftentimes on par with their more traditional counterparts. It wasn’t that long ago that many HR professional may have viewed career colleges—particularly online career colleges—as carrying less weight than traditional colleges, but asrepparttar 139022 online education space evolves and faculty members and curriculums at online schools catches up with those at traditional schools, more and more HR executives are realizingrepparttar 139023 validity of degrees earned online or through career colleges. In fact, to some, an online degree represents a certain career ambition, technological prowess and commitment to seeing something through torepparttar 139024 end on behalf ofrepparttar 139025 applicant.

I’m Afraid I Won’t Learn Anything New Or Valuable

Many potential students are fearful ofrepparttar 139026 fact that their trouble to go out and earn their degree might be all for naught—thatrepparttar 139027 classes won’t teach them anything they hadn’t learned already in their professional experiences.

As anyone who has ever taken so much as a single class at a career college or online school will tell you, however, this perception couldn’t be further fromrepparttar 139028 truth. Classes at any accredited university are taught by qualified experts with lots of experience in their chosen field, while you will also be surrounded by classmates who bring their own, unique experiences to share. Whetherrepparttar 139029 “classroom” is physical or virtual, you will learn more than you ever imagined from those around you.

Another point to consider is that most career colleges are centered around a team learning approach, in which students learn not only from their instructors, but from other students as well. With this approach, you’ll engage in dialogues with other students who have much to share from their own work experiences, and you’ll gain valuable lessons that you can take back and immediately apply to your own work.

Why Make The Move?

In today’s modern learning environment, with numerous career and online schools focused entirely on their educational needs, adults have nothing to fear in a return to school – and so much to gain. Here are some ofrepparttar 139030 main reasons more adults than ever are going back to school:

Career advancement or transition. If you’re not currently working atrepparttar 139031 job of your dreams, nothing can change that faster than a more advanced degree and additional expertise.

To complete a degree from years ago. Plenty of first-time college students leave before they earn a degree, and a return to college is a supremely satisfying way to take care of that unfinished business.

To set an example for their children. What better way to encourage your growing children to pursue a college education than getting one of your own?

To fully prepare for running their own business. Whether you’re interested in opening a B&B or your own accounting firm,repparttar 139032 perfect college program is available online or on-campus.

Returning to school is a big step, but it shouldn’t be an overwhelming one. For those who planrepparttar 139033 move properly and take aim on getting all they can out of life, it can berepparttar 139034 best decision they ever make.

Introduction to EMI/EMC

Written by Lieutenant Colonel Anil Kumar Nigam

Continued from page 1

The use of many items of electronics equipment in close proximity inrepparttar hospital environment means thatrepparttar 138904 same sort of EMC problems are encountered as with other types of electronic products. However there are some special features ofrepparttar 138905 hospital EM environment:

• Failure of medical devices can lead to injury or death. • Some equipment found in hospitals is intentionally designed to emit electromagnetic energy, often for therapy. Other equipment, which may be located nearby, is designed to detect very small physiological signals. This combination hasrepparttar 138906 potential to create EMC Problems. • Also in hospitals, there isrepparttar 138907 question of whether to ban or restrictrepparttar 138908 use of mobile phones. They improve communications but can interfere with critical equipment. • Many medical devices are connected directly to patients. For mains-powered devices,repparttar 138909 designer must prevent electric shock as well as ensure EMC. Electronic equipment is constantly evolving, so there is alwaysrepparttar 138910 possibility of new problems arising, e.g. interference from new types of mobile communications devices.

Remedial Measures: Ensuring EMC ofrepparttar 138911 devices/ components: Electromagnetic compatibility describes a state in whichrepparttar 138912 electromagnetic environments produced by natural phenomena and by other electrical and electronic devices do not cause interference in electronic equipment and systems of interest. In order to reach this state, it is necessary to reducerepparttar 138913 emissions from sources that are controllable, or to increaserepparttar 138914 immunity of equipment that may be affected, or to do both. To try to eliminate all possibility of interference by decreasing emissions and increasing immunity further could incur a high cost to industry and could prevent new technologies from emerging. For example, a restriction loweringrepparttar 138915 transmitting power of cellular telephones so that consumers could place their cell phones on top of any electronic equipment might compromiserepparttar 138916 performance and economic viability of such communication systems. Onrepparttar 138917 other hand, a requirement that all commercial electronic equipment perform without malfunction at ambient levels of 50 V/m would place a financial burden on manufacturers of a large range of equipment. The following are some ofrepparttar 138918 techniques used to counterrepparttar 138919 effects of EMI:

Source Elimination: An effective technique to eradicate interference is through identification and elimination ofrepparttar 138920 source. In theory, this represents arguablyrepparttar 138921 most effective of any measures, but is not practical in most situations, whereas this would requirerepparttar 138922 source to be periodically or permanently disabled from operation. Grounding a grounding point represents a common reference point for a device or multiple devices that functions to ensurerepparttar 138923 safety orrepparttar 138924 equipment and operator, and its effects provide some immunity to noise and interference. Certain transmission and other Electronic equipment require adequate grounding to ensure proper operation. The Conductor used to groundrepparttar 138925 equipment should berepparttar 138926 shortest necessary length to avoid a ground loop condition. This could result in energy transfer through conduction to connected devices.

Filters The use of filters allows selected frequencies to pass through torepparttar 138927 connected device, while rejecting or attenuating any frequencies that are outsiderepparttar 138928 filter specifications. Examples of filters include low-pass, band-pass, and high-pass.

Shielding. An effective manner used to minimize, and in some instances eliminate, EMI is to effectively shield components from interaction with electromagnetic energy. This technique is often expensive and causes major design engineering challenges, especially to fully shield a device, which requires that conductive material completely encloserepparttar 138929 equipment or circuitry. Any separation inrepparttar 138930 shielding material reducesrepparttar 138931 effectiveness Ofrepparttar 138932 shielding technique.


With ever increasing use ofrepparttar 138933 spectrum due to modern communication equipments and also use of latest digital processing techniques for most ofrepparttar 138934 devices there is a need for laying downrepparttar 138935 guidelines for Emission standards. The extent ofrepparttar 138936 spurious radiation by any device should be limited torepparttar 138937 extent possible without increasingrepparttar 138938 cost ofrepparttar 138939 product. Various governmental and nongovernmental agencies must come forward at national and international level to coordinate and standardizerepparttar 138940 permissible radiation limits
