Continental drift was an idea raised in early 17th century by Sir Francis Bacon, as he wrote of the apparent shoreline fit of opposite sides of the Atlantic which was much like pieces of a puzzle (Figure 1). The fit was computed by Sir Edward Bullard in 1960s later (Figure 2). Later in 1912, Alfred Wegener, a German geophysicist who was the first to propose the continental drift theory with a mechanism, suggested that all the lands were once joined together as a supercontinent – Pangaea, which…

one, or a combination of actions. Upon sensing this change, the control panel produces an audio or visual signal to alert the occupants and the relevant authorities such as firefighters and security agents. All the components of the alarm system are connected to the control panel using the appropriate cables or secure wireless links. And there may be outgoing communication cables to the security or firefighting companies and sometimes to a central or remote control office where applicable.…

Our history is full of events that played roles in changing our point of view about the world that we live on. One of those events was the Moon landing in 1969. It was a huge advancement in technology. Everyone was amazed when they know that humans were able to go to the moon and land on it. It was one of the United States greatest accomplishment because for the first time human were able to step onto the Moon. However, the United States was not the only country that doing research about rockets…

Leaders of all major nations worldwide are aware that space exploration is indispensable in establishing a super power of a country. The Space Race between the United States and Russia is an illustration of this belief of superiority; each country during this period tried one-upping each other to establish dominance. NASA during the span of this race spent 23 billion dollars (Dickinson). Because of these high priced missions, leaders must question whether space exploration is a beneficial…

Abstract Mobility of visually impaired people is restricted by their incapability to recognize their surroundings. According to the World Health Organization (W.H.O.) in 2012, out of 7 billion global population there were over 285 million visually impaired people and 39 million were totally blind out of which 19 million are children ( below 15 years). This means that someone in our world goes blind in every five seconds and a child in every minute. Over 90 percent blind children obtain no…

Global Warming is a topic that plagues most of the world because no one really knows what is causing it, if anything at all. There are 3 theories on why the world is warming and what the cause may be: human activities, natural phenomenon and that the globe is not even warming at all, just natural fluctuation. Regardless of the reason behind global warming, people want to come together and stop the Earth’s warming or prevent it from happening. The fast melting Artic Sea ice is thawing faster than…

The Environmental Effects of Hurricane Katrina: An Annotated Bibliography Brooks, Matthew, Stouffex, Philip. “Effects of Hurricane Katrina and Salvage Logging on Bachman’s Sparrow.” 26 Jan. 2011, http://www.bioone.org/doi/abs/10.1525/cond.2010.100019 Bachmann’s Sparrows are at a near threatened status, so the effects of Katarina were expected to be detrimental to their environment. These sparrows make their homes in the longleaf pine tree located in the savanna area. The path of Katrina…

Climate change is a global-scale atmospheric externality. It is an issue that must be understood and addressed globally. Environmental trends based on scientific and observed studies have shown an increase of greenhouse gases in the atmosphere, an increase of the Earth’s surface and ocean temperature causing a decline in sea ice, and more prevalent extreme weather patterns- all due to human influence. However, trying to understand each of these trends separately will not fully explain the causes…

2.5 Proposed Architectures for SDN in WSN The novel idea of exploiting OpenFlow technology to address reliability issues in sensor networks was presented by (Arif Mahmud and Rahim Rahmani, 2011) at the IEEE International Conference on Computer Science and Network Technology while the first architectural proposal was presented by (Luo et al., 2012) in the form of Software Defined Wireless Sensor Network (SD-WSN). Up until now, very limited research work is carried out in this area. Some of the…
