Once the student achieves masteryof a topic, he or she moves on to the next topic in a self-paced learning model, advancingindependently of one another. The effectiveness of this method remains the subject of muchdebate; however, many organizations and individuals, including the Bill & Melinda Gatesfoundation, Google, Netflix CEO Reed Hastings, and Irish Entrepreneur Sean O’Sullivan,believe that the Khan method is the future of education, and have provided financial backing ofover $15.5 million collectively to see it succeed.

tolearn how to get to a place when we are driving. So by default, we are equippedwith the basic skill set of self-learning. Unfortunately that basic skill set of self-learning doesn’t always get fully incorporated into our careers. Students tend tohave problems in adopting a learning style [1]. Some students understand theimportance of self-directed learning and develop an appreciation to be a self-directed learner. “Self-regulated learners are aware when they know a fact orpossess a skill and when they do not” [2]. Self-directed learning is learning with the aim of implementing theinformation into one’s life; academic, professional or personal. “The key tocontinuing professional development is learning, which comes about in differentways

According to most analysts, the current credit crisis has a directlink to mortgage business in the U.S. In this case, U.S. banks made high-risk loans to individualswith bad credit accounts. The problem became evident when bank rates in the U.S. rose from 1%in 2004 to 5.35% in 2006 (Tse and Cho, 2007). Such a rapid rise in interest rates made thehousing market slow, and many homeowners who were scarcely able to afford their mortgageswhen they were low faced unmanageable increases in their monthly mortgage

Convenience, TeachingTechniques, and Construction Management.Introduction:Typically, a three credit course at the collegiate level requires a total of 45 hours of direct contactbetween the students and the instructor. Many institutes of higher education use the regular falland spring semesters format to spread these 45 educational hours over a period of four months.Many others teach such courses over the summer session where it is more intense since it is a sixweek period. There are advantages and disadvantages for both formats, and there are severallimitations for the summer format.Few colleges and universities use a shorter time frame to offer courses. Some institutes utilizethe winter break to offer three week courses like Lone Star College [1

carry significantly more information but limited in distance to a fewhundred meters. Acoustic communication is the most versatile and widely used technique inunderwater environments due to the low attenuation (signal reduction) of sound in water.This is especially true in thermally stable, deep water settings. On the other hand, the use ofacoustic waves in shallow water can be adversely affected by temperature gradients, surfaceambient noise, and multipath propagation due to reflection and refraction. The much slower speed of acoustic propagation in water, about 1500 m/s (meters per second),compared with that of electromagnetic and optical waves is another limiting factor for efficientcommunication and networking [1]. Therefore, acoustic waves

ideas tangible. There are complications that can occur with the heart valves from diseases that affect the heart’s function. The heart valve that is most commonly affected is the mitral valve (shown in Figure 1). It is understandable that any complications with the mitral valve can cause serious malfunction of blood pumping. Common complications are mitral valve regurgitation and mitral stenosis. With mitral valve regurgitation, blood from the left ventricle leaks into the left atrium. This can be due to several factors: the leaflets function regularly, but there is annular dilation or leaflet perforation; leaflet prolapse that occurs due to papillary muscle damage or lengthening, or; leaflet motion is restricted [1].

Conventional coolants, lubricants and other heat transfer fluids used intoday’s thermal systems typically have relatively poor heat transfer properties. Hence, utilizingthe phase change process to increase the heat transfer properties of conventional fluids is anotherpromising direction. Recently, the author has proposed a new “nanoemulsion heat transfer fluid”system in which one lower boiling point liquid is dispersed into another immiscible liquid

shortages and crises in the1970s and recently global warming, climatic changes, and environmentalpollution made it necessary to look for alternative energy sources. The sources offossil fuel are being depleted. Fossil fuels are not renewable and cannot beproduced naturally. Renewable energy is seen as an alternative to fossil fuelsbecause of three main reasons [1]. Renewable energy is not depleted as fossilfuels, so it may potentially solve energy shortages and contribute to economicgrowth. Fossil fuel prices are increasing, while renewable energy can be a cheaperalternative. In addition, carbon dioxide (CO2) is considered to be the main driverof global warming and climate change, while renewable energy is clean. Renewable energy is an abundant
