In this article‚ I present evidence that psychological pitfalls played a crucial role in generating the global financial crisis that began in September 2008. The evidence indicates that specific psychological phenomena—reference point–induced risk seeking‚ excessive optimism‚ overconfidence‚ and categorization—were at work. I am not saying that fundamental factors‚ such as shifts in housing demand‚ changes in global net savings rates‚ and rises in oil prices‚ were not relevant. They most certainly

electromechanical device which generates an electrical output directly proportional to the speed of the rotating systems. Tachogenerators are basically transducers. This transducer converts the speed of rotation directly into electrical signal. The angular speed is converted into a directly dependent voltage signals. The voltage thus generated is fed to a speedometer for speed measurement and /or used as a feedback signal for controlling the speed of a rotating shaft. An electromechanical generator

Lab# 1 The Node-Voltage Method of Circuit Analysis By: Abstract This report used KCL and Ohm’s law to calculate the node voltages and compare them to the measured node voltages after building the circuit. The calculations were obtained by hand using node analysis. The experiment was simulated on PSpice and the results were verified to hand calculations. The circuit was built in the lab and the results were measured with a digital multi-meter and compared to the calculated values‚ and

Chapter 3 VOLTAGE SAG/SWELL MITIGATION USING DYNAMIC VOLTAGE RESTORER (DVR) 3.1 Voltage Sag Mitigation Methods Power quality problems cannot be avoided for the consumers (end users) who are directly connected together by the interconnected systems. Therefore‚ consumers must protect themselves from PQ problems with mitigation or power conditioning devices. It is researched by EPRI that 90 % of all power quality problems are voltage sags in the USA and it is assumed that the European power network

Compare how time is presented in ’Hour’ and one other Poem Both poems ’Hour’ and ’To His Coy Mistress’ present the power time has between two people. ’Hour’ is a poem about two lovers who have one hour together and explores the ideas of material possesions and a modern reinterpretation of love. Where as ’To His Coy Mistress’ is a poem where the man is trying to convince the woman to sleep with him and exploring the idea of living and enjoying your life whilst your young. Both of the poems use

This photo was taken while I was on a dog sledding trip in the forests of North Bay. The dog in the photo Moose‚ paid no attention to me. This was very challenging‚ because my original idea for the photo was a close up of him so I could remember his cute face. As soon as I took the photo‚ I immediately thought of Alice and Rose’s troubled relationship. Rose is usually the one trying to reach out and connect with her mother‚ but unfortunately her mother doesn’t reciprocate. The in-between space from

How and why is one social group represented in a particular way? We are all shaped by the culture and environment that we grow up in. As we grow up‚ we are taught certain things and are bombarded with images. These later become the norm and shape society. If we live in a society that is constantly showing woman in a certain way‚ it becomes the accepted image of how woman should act and behave. If we live in a society which says woman should have a certain place within society that becomes normal

Why use regulated power supplies? The ideal voltage-regulated power supply would have the following features: 1. Zero output impedance at DC and at all frequencies 2. Zero regulation (constant DC output voltage) for a wide range of AC line voltages and over the entire range of load currents that are required by the powered circuitry. 3. Zero power dissipation. 4. Instantaneous recover from changes in line voltage and load current. 5. Overload protection so that normal operation is automatically

Voltage: Ohm ’s Law and Kirchhoff ’s Rules ABSTRACT Ohm ’s Law and Kirchhoff ’s rules is fundamental for the understanding of dc circuit. This experiment proves and show how these rules can be applied to so simple dc circuits. INTRODUCTION In the theory of Ohm ’s Law‚ voltage is simply proportional to current as illustrated in the proportionality‚ V=RI. As shown in this relation‚ V represent voltage which is the potential difference across the two ends of a electrical conductor and between
