TERM PAPER: DOT.COM BUBBLE vs RAILWAY MANIA INTRODUCTION Our world has suffered numerous economic crisis ever since we had a concept of money. One may argue that economic crisis and economic growth go hand-in-hand. A very frequent source of economic crisis are speculative bubbles which essentially tailspin our economy into a euphoric state. They fill our investors with irrational exuberance, and coax them to go on an expensive investing spree. This goes on until the speculative behaviour…

In the current business environment globalization has led to organizations to hire foreign citizens and even to operate in foreign nations to help in expansion of the businesses. However, there are requirements for a foreign citizen to work in the stated country which are stated in the labor laws. One of the requirements for such is for the individual to have a visa that will help him to be allowed in the company that hew hired. In the US the H-1B visa is required for the foreign individual to…

the extremely personal character experiences in Skyfall, Spectre attempts to make things even more emotionally charged. Regrettably, Spectre spends its lengthy runtime (roughly two and a half hours) piggy-backing off the events of Casino Royal, Quantum of Solace, and Skyfall. That’s right, apparently one man – Christop Waltz’s character – takes credit for the trauma to Bond’s psyche (and death-filled love life). In other words, Waltz, who barely even appears when you look at the big picture,…

most recent model of the atom. It is based on quantum mechanics. Quantum mechanics are the use of the quantum theory as a means to studying the structure and behavior of atoms and molecules. The quantum theory is a theory in physics based on the principle that both matter and energy behave as both particles and waves, and that matter and energy are composed of tiny units of electromagnetic energy called quanta. The electron cloud model and the quantum mechanics model are two different models…

Model descriptions SWAN model The SWAN model [12,18] is based on the spectral action balance equation rather than the spectral energy balance equation. The evolution of the action density N is governed by Komen et al. [13]: ∂N/∂t+∇_x ⃗ ∙[((c_g ) ⃗+U ⃗ )N]+(∂c_θ N)/∂θ+(∂c_σ N)/∂σ=S_tot/σ where, N(σ.θ) is the action density spectrum, x is space, t is time,θ is wave direction, σ is relative frequency, S_tot is the source term total, and c_g represents the propagation velocity. The first term in the…

The SEM produces a largely magnified image by using electrons instead of light to form an image. A beam of electrons is produced at the top of the microscope by an electron gun. It consists of an electron gun to produce high energy electron beam. A magnetic condensing lens is used to condense the electron beam and a scanning coil is arranged in-between magnetic condensing lens and the sample. The electron detector (Scintillator) is used to collect the secondary electrons and can be converted…

Photoacoustic spectroscopy (PAS) is a tool to study thermal emission resulting from non-radiative relaxation followed by absorption of radiation. PAS was studied primarily by Alexander Graham Bell, John Tyndall, Wilhelm Rontgen and Lord Rayleigh in 1884. For the history of PAS, was not until 1975 that photoacoustic spectroscopy started to be used as a wide range of different applications. This technique provides the following main advantages over the known types of spectroscopy. The advantages…

T Introduction Jean Piaget a well-known and first psychologist to make a systemic study of cognitive development. He was a very talented scholar and his first scientific paper, on the Albino Sparrow published at the age of ten. After he received his doctoral degree at the age of twenty-two, Piaget formally began his career that would have a profound impact on psychology and education. Today, Piaget is best known for his research on children’s cognitive development. He studied the intellectual…

Most people imagine time as a constant. Physicist Albert Einstein illustrated that time is an illusion that it is relative which it can differ for different observers depending on the speed through space. To Einstein, time is a fourth dimension and space is described as a three-dimensional field, which provides a traveler with coordinates such as length, height and width showing location. Time provides one more coordinate direction although conventionally, it only moves forward. Time…

by describing light as a wave. Some other properties such as emission and absorption are better explained by treating light as a particle. The correct or exact nature of electromagnetic radiation is not clearly known, as it has the development of quantum mechanism in the first quarter of twentieth century. Wave properties of electromagnetic radiation Electromagnetic radiation consist of oscillating magnetic and electric…
