Differential equation

Column A shows the amount of each color ‘eaten’ by the predator. The colors with larger numbers in column A experienced negative selection pressure. Column B shows the expected number of each phenotype to be collected based on chance probability. The equation used to get the value 2.5 is as follows: Number expected = Total number collected (25) / number of phenotypes (10) Column C shows the number of organisms with each phenotype that survived predation. The number in column A was subtracted…

flexibility and carry large loads. This solution serves as the guide for the initial concept with some practical changes. Euler Buckling of Columns The constrained buckling column induces higher modes to carry larger loads. Based on the Euler buckling equation (Figure 2.1), mode has a n2 effect on the buckling load, so inducing higher modes increases load capacity exponentially. This could be useful in this design because the weight bearing member can remain flexible and still potentially…

deteriorate when they are out of the labor force. Occupational segregation may be due to women choosing occupations, such as nursing and teaching, with skills that are useful in home production. The wage gap may be also the result of compensating wage differentials. Some may prefer safer jobs, less effort-intensive jobs, and shorter commute times. Moreover, differences in productivity characteristics, education, experience, industry, occupation, etc. will result in a wage gap…

The relationship between the input and the output can be quantitatively described in form of a mathematical model. This description could be outlined through a parametric model which uses a group of parameters usually incorporated in a few differential equations governing the physics of the system or a non-parametric model through measurements of the system at a large number of points [35]. Parametric approach often requires an in depth knowledge of the system and uses more assumptions in…

They postulated that the collective memory is shared via the dance language and presented a model that describes the colony's decision-making process using system of non-linear differential equations that has most affect on the total foraging success. This model, however, disregarded some aspects of honey bees foraging process, like individual behavior. In many papers this problem was referred, with a still open question about how important…

would be multiple job openings to generate and design. "Consider this: manned mission to Mars just might single-handedly salvage what's left of the engineering profession here in the U.S., where interest in anything involving second-order differential equations has been on the wane since the mid-1980s," states Karen Augustin, Chief Executive of Design News (Auguston [1]). Comparatively to foreign countries, engineering professions have not been needed as much as they used to, but if America…

A catalyst layer is usually the slimmest layer in a PEM fuel cell; however this is an extremely complex component because of its porosity, several phases, and reactions (Spiegel 2008). An efficient catalyst layer should provide several functions at the same time; transporting the electron and the proton, supplying oxygen and hydrogen and water management. The structure and composition of the catalyst layer affects all these roles. Optimization of the catalyst layer can provide for all these…

John Nash is now a well-known mathematician. He is commonly recognized as the only mathematician to win the Nobel Prize and as the mathematician that the movie A Beautiful Mind is based on. While people are now aware of John Nash’s story, it was not previously well known. John Nash grew into a brilliant mathematician, was diagnosed with schizophrenia, and persevered through obstacles to continue working in mathematics. John Nash was born on June 13, 1928 in Bluefield, West Virginia where he…

Have you used a computer today? Well if you have, I bet you thought all the stuff you stored on it was safe. I am going to tell you why it is not. We should not rely on computers so heavily because people store too much personal information on their computers, terrible cyber security, and hackers are too advanced. A computer is an electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program. We use these electronic…

Some women decide to work until they no longer can work because of the pregnancy. The second reason would be post-pregnancy when the mother needs to recover and also if they breastfeed. Lastly, once they have children in the equation the mother has to think about what job is best for her in a case where there is an emergency. Not just mothers also people that may have to take care of the elderly or students. Taking care of the elderly would be the same as taking care of children…
