INTRODUCTION When thinking of starting a contracting business for solar panels‚ many economic issues and concerns play a factor in the decision making process. Having a concern for the environment and knowing that solar panels have a cost saving for both households and business seems to be reason enough to start a business. However‚ before making such a financial investment you should first take a look solar panels in the economy in terms of (i) GDP growth rate‚ (ii) interest rates‚ (iii) level

SEPTEMBER 2004 1063 Which Model to Use for Cortical Spiking Neurons? Eugene M. Izhikevich Abstract—We discuss the biological plausibility and computational efficiency of some of the most useful models of spiking and bursting neurons. We compare their applicability to large-scale simulations of cortical neural networks. Index Terms—Chaos‚ Hodgkin–Huxley‚ pulse-coupled neural network (PCNN)‚ quadratic integrate-and-fire (I&F)‚ spike-timing. A. Tonic Spiking Most neurons are excitable‚ that

Solar Nebular Hypothesis The idea behind the Solar Nebular Hypothesis is that the solar system was condensed from an enormous cloud of hydrogen‚ helium‚ and a few other elements and rocks. Around five billion years this cloud of materials began to spin and contract together into a disk shape under their own gravitational forces. The particles started combined together‚ protoplanets‚ to eventually form planets. A great mass of the material eventually began to form together‚ protosun‚ and make

In Planet of Slums‚ Davis discusses the roots of slums in relation to urban poverty in the post-modern era as well as its social‚ political‚ economical and ecological consequences. This essay might ring a bell to many as a duplication of the famous UN-HABITAT’s report in 2003 on the challenge of slums; however in my opinion‚ what Davis is attempting to do here is an exploration to the roots of urban poverty on a global scale rather than within local state governance‚ and also with references to the

“I felt like the moon‚ the stars‚ and all the planets had fallen on me.” Harry S. Truman‚ our thirty-third president of the United States‚ spoke this on April 12‚ 1945. This was a significant day in which two major things happened; President Franklin D. Roosevelt died unexpectedly‚ and Harry S. Truman was sworn in as president. Henry L. Stimson‚ Roosevelt’s secretary of war‚ who later became Truman’s‚ reintroduced the proposal of the Manhattan Project and its person in charge‚ Major General Leslie

Database Models and Legacy Systems The evolution of the information age demanded robust management systems for storing large volume of data‚ efficiency in retrieval‚ and enhanced data security and sharing; hence‚ the development of databases from flat file systems. Despite this advancement in technology‚ many organizations such as Colorado Financial Reporting System (COFRS) continue to use legacy database systems.

How Aging Effects the Structure of Our Skin “Age related skin changes are the result of either intrinsic factors‚ or genetically programmed changes‚ and extrinsic influence which includes the environmental wear and tear on the skin.” Some estimates state that from 80-99% of what we see on our skin as adults is the result of these environmental influences‚ in particular exposure to the sun. Some of the visible differences of aged skin are the exaggerated expression lines (wrinkles)‚ a sallow skin
