Abstract

Infinite square well potential is one of the most elementary quantum mechanical system. The calculation of this case is not too complicated, however, it can show the differences between quantum world and classical world with clearly. In this letter, we expand the discussion about the infinite square well potential for dynamic potential well  by involving relativistic corrections. The dynamic potential is defined as potential wall that depend on time because the potential can moving with constant velocity. The Dirac equation is used to describe condition in the potential well. By this consideration, we hope the result will be useful in the development of nanoelectronic devices. To obtain solution of probability density of Dirac particles that depend on space and time, we transform the Dirac equation into hyperbolic coordinates and the differential equations can be solved by separation variables method.

Abstract

Nias Island is an island located west of North Sumatra dipesisir which has a fairly high level of seismicity. This paper discusses the problem of forecasting the occurrence of tectonic earthquakes for the island of Nias, located on the site: 0º19LU - 1º82LU and 96.97 BTº- 98.53ºBB. By using the data a powerful earthquake that caused damage. Tectonic earthquake forecasting is done with method 3 parameter Weibull distribution, two parameter Gumbel distribution and exponential distribution of parameter 1. using the data as much as 47 damaging earthquakes from year 1960 to 2012, which is a major earthquake (mainshock) the magnitude of 6.0 - 9.1 SR. To calculate the waiting time distribution forecasting using a third used the software Mathematica for Windows version 8.0. Making the program requires data - input data relating to waiting times of earthquakes in the past to the present. By making this prediction program to predict the timing of the tectonic earthquake in Nias Island.So predictable subsequent tectonic earthquake in Nias island territory will occur on September 4, 2013 when predicted using the Weibull distribution with three parameters, dated April 5, 2013 if the forecast using the Gumbel distribution with two parameters and dated September 4, 2013 when predicted using the method of distribution exponential with a parameter.

Abstract

Noise is one of the waveforms that can be heard by human hearing. Truth is the activation of sound that can not be done. The effect of sound on humans not only affects the auditory organ, but also can affect other organs, such as narrowing of blood vessels and heart system. Truth caused by transportation is very disturbing but not all of it is caused by transportation. Wisdom can also occur in public places or facilities such as hospitals and children's playgrounds, one of the children's and children's favorite theme parks is TimeZone Mall. You can do research to measure and learn the level of playground at TimeZone Mall Taman Anggrek and TimeZone Tamini Square. The average measured result of 6 readings with calculations per 60 minutes in the orchid mall's time zone is 70.5 dB and the tamini square time zone is 65.33 dB. In the time zone of the orchid mall park and the tamini square time zone there is no value beyond the threshold limit (85 dBA). With no measurement results exceeding the workspace limits for uninterrupted or preventive work. Keywords: Noise, Timezone Mall, playground, sound
