Essays on Holes

It’s a principle that provides the basic and the essential part in the mathematics of sorting and even counting. This principle was introduced by Johann Peter Gustav Lejeune Dirichlet in 1834. He called it the shelf principle or drawer principle. However, many people appreciate his insight and call it the Dirichlet drawer principle. The name pigeonhole was introduced in 1940 by Raphael Robinson. In the literal sense, pigeonholes refer to shelves or holes used to place pigeons. Thus, the principle roughly states that if one has a given number of boxes and a given number of items to ...

Impact Mitigation

Intelligent locomotive bumper designs have been touted as possible life-savers for pedestrians. Paden, Kelly, Hines, Botham and Simms explored the feasibility of a life-saving locomotive bumper (103). There were several motivations behind their paper. Perhaps the most important one was the high number of pedestrians that were killed every year in train impacts. Between the years 2007 and 2012, about 10,950 non-suicide deaths were attributed to train impact on humans. Including suicide deaths on railroads, 28,800 pedestrians were killed during that 6-year period. Also, Paden et al., noted that passenger trains served densely populated areas ( ...

Aircraft Cabin Safety

Accidents are complex systems that happen when multiple failures and factors accumulate and finally blow out of proportion. The failures and factors that accumulate are jointly sufficient to cause various types of accidents. Aircraft systems are complex systems that have the potential multi-causal conditions. The conditions rarely arise but when they do they create a possible trajectory for an accident. Most of the factors that cause these accidents are always present way before they are triggered and an accident occurs. Additionally, most of them are actually triggered by the organization of the system itself due to its design, the ...

Polymers cells are the next-generation class of photovoltaic since they promise realization of light weights, mechanically flexible, larger area devices. The room temperature solution processing can be used in fabricating these devices. High-efficiency conversion power of about 10% has recently been obtained in tandem polymer cells (Huo et al., 2015). In single-junction, it’s achievable through lowering the density state to a level lower than the electron acceptor and the conduction band of the semi-conductor. Photovoltage is electromotive force obtained by a photosensitive material due to inducing radiant energy; photovoltaic relates electric current produced at a junction of two ...

Sinkholes; Made by nature or humans?

Abstract Sinkholes seem to swallow the earth and everything sitting on the surface. Some sinkholes are small and have relatively no effect on humans or property. Some sinkholes are very large and will leave ga[ing holes in the landscape. Sometimes these large sinkholes will devour a road and cause harm to the humans who live, work, and travel where the sinkhole is located. For example, a series of sinkholes and a landslide occurred simultaneously in Harbor, Oregon. This sinkhole was a combination of nature and human activity. Many sinkholes are caused by human activity that nature decides to ...
