Overview

Polyvinylidene fluoride is one of the polymers that are used as membrane material. This is because of its outstanding properties. Besides its comparatively high amount of fluorine, the polymer also has a high level of crystallinity. The result of these properties are exhibited in the performance of the Polyvinylidene fluoride polymer. For instance, the chemical stability of Polyvinylidene fluoride in chlorinated solvents and environments that are highly caustic and acidic is very high. Another property of the polymer is its hydrophobicity. This means that it is not compatible with water. This would create challenges if the polymer were to ...

The industrial revolution changed the face of American society in a multitude of ways, not least of which was the role of the government in the relationship between businesses and workers. The emancipation of slaves in the aftermath of the Civil War irrevocably altered the way aspects of the economy operated—especially that of the Southern states and of the agricultural sector. From that point clear through to the present, the relationship between employer and employee has been in constant question and flux, with labor unions and government regulations having significant impacts on the overall state of workers’ rights ...

Electromagnetic induction can be defined as the production of electromotive voltage or force across an electrical conductor when it dynamically interacts with a magnetic field. There are numerous uses of electromagnetic induction, for example, in electromagnetic elements such as transformers and inductors, electric motors, generators, and transcranial magnetic stimulators.

Applications of Electromagnetic Induction

Electromagnetic induction is an extremely useful phenomenon with various applications. It’s applied in the creation of eddy currents, which are swirling currents set up in conductors in response to changing magnetic fields. Electrons in the field swirl in a perpendicular plane to the magnetic field causing loss or transformation ...

Summary

While all the components of a brake system are important, it is imperative to acknowledge that some components play significant roles in the system as compared to others. One such component is the brake pad. In most cases, the brake pad is referred to as the friction material. It is responsible for generating the friction which opposed the movement of the wheel thus causing a stop to the movement of the automotive. This report is aimed at selecting a section or component of the brake system and presents its modification. As a consequence, the report highlights and discusses the ...

Bergson defines time as “our self which endures” (Bergson 24). However, time can be defined as a set of events that can be chronologically recorded or identified in the sequence of past, present, or future. The concept of time flux, as indicated by Bergson, is a phenomenon where time is perceived as a progression of “states,” each of which reveals that which comes after it and “contains that which precedes it” (Bergson 24). Bergson adds that when this happens it is said to create various “states” when an individual already “passed them and turn back ...

Fuel Cell Technologies in Passenger Cars

Fuel Cell Technology The last decade is characterized by the rapid development of research activity in the field of fuel cells, thus, creating the conditions for their uptake in electric systems. The basic fuel cells’ operating principle has been known for 150 years. However, a variety of technical and financial problems had kept them on the margins of technological applications (Brandon & Hart, 1999). The basic difference between a fuel cell and batteries is that while batteries store energy, fuel cells directly convert a fuel’s chemical energy into electricity by an electrochemical reaction (i.e. Without requiring combustion or movement ...

Literature Review

Abstract Innovations and modifications that produce cost reductions and enhance performance have driven the evolution of the classic solid rocket and the liquid bipropellant rocket into hybrid models that integrate the predominant solid and liquid model features into more sensical, more economical fabrications of design. The commercial spacecraft demands for aerospace propulsion have also evolved to include a market for environmentally sustainable hybrid rocket engines that has yet to fully mature to the Technology Readiness Level (TRL). Numerical modeling has been used as a tool to test the feasibility of new solid fuel types. ABS has been considered as ...

Fluxus art movement or simply Fluxus, started as a loosely defined group of artists, musicians and poets who had nothing more in common than a vision of life integrated in art, and art as the living of a life. More than 50 artists were associated with the art movement, creating music and anti-music, art that was not adherent to ‘museum defined standards’ and poems that were not traditional. This movement caused social and economic change in the society in the 1960’s (when it was first started) and had effects whose fruits we reap even today. This movement can ...

Wave and Wind Power Generation

Wind Physics Basics Wind is atmospheric air which is in motion Energy Source The earth surface absorbs solar radiation differently. Some parts absorb more radiation than other. This creates pressure zones. As a result of pressure, air moves from high-pressure zones to low-pressure zones. This causes atmospheric air motion known as wind. Wind is a renewable source of energy. It is constantly available free of charge (Bhattacharyya, 2011).

Spatial scales

Atmospheric air motion can be categorized depending in terms of spatial scale. Four spatial scales identified include planetary scale, synoptic scale, mesoscale, and microscale. There are various types of spatial scales ...

Abstract

Permanent magnet synchronous motors (PMSM) are a type of motors that have permanent magnets mounted on the rotors instead of the rotor windings. This particular design gives the motor a few advantages over ordinary induction synchronous motors. The magnets attached to the rotor do not require excitation, which reduces the power consumption in PMSM. This gives the motor high operational efficiency and reduces the motor active diameter. PMSM are therefore associated with applications that require high torque but have limited operation space. The permanent magnets suffer from flux leakage and are therefore aligned in a pattern that minimizes flux ...

A.N. Whitehead famously claimed that all Western Philosophy was nothing more than footnotes to Plato. But long before Plato or Socrates, there were many Greek thinkers who looked for answers to many of the same questions that Plato had asked. Two of the most famous of these thinkers were Heraclitus and Parmenides. Both of these philosophers were thinkers were pre-Socratic metaphysicians and asked questions related to the nature of reality. Since they were both two of the oldest philosophers in Europe, many of their ideas seem quite strange to modern readers and the fact that their works only exist ...

Visualization tools

Data is very important in the modern world because information is the most valuable asset in the society. Most of the useful information can be found online and can be used in any of the visualization tools so that the display can be good. The information is exchanged through the Internet and people can use a variety of information that is available for the people who know how to look for them. Designers are constantly developing new and interesting tools which are helping certain data become noticeable and beat the competition. There are Charts.js, which are simple to use ...

Treasury Risk Management (a) (a.1)

The forward rate is:

Forward rate = 1.4010 + 0.095 Forward rate = 1.4105 Payment in six months: 8.5 million euros. Payment in GBP = 6,03 million GBP (a.2) 8.5 million EUR are 85000 options paid: Call: 1.2 * 85000 = 102000 GBP in paid premium Put: 1 * 85000 = 85000 GBP in paid premium Both strike options are different from the two values of currency exchange 1.37 EUR/GBP and 1.43 EUR/GBP. The results will be: 8,5 million EUR / 1.42 = 5,985,915.49 GBP – 102000 GBP = 5,883,915.00 GBP 8,5 million EUR / 1.4180 = 5,994,358.00 GBP – 85000 GBP = ...
