When Nicolaus Copernicus discovered the Earth wasn’t the center of the Universe, everything changed. When Frederick Miescher discovered DNA, everything changed again. When quantum physicists discovered our physical universe isn’t real, that it’s a hologram - everything ... wait! Nothing changed - yet. Now "Butterflies are Free to Fly: A New and Radical Approach to Spiritual Evolution" examines how quantum physics and recent scientific experiments are radically changing our understanding of life, our reality, and our spirituality, giving us a new model for the way our universe works and the practical steps to take toward true joy and excitement and peace of mind.

The purpose of this research is to determine if security measures currently in place with military UAVs can sufficiently remedy known security gaps with regards to civil UAVs. This research methodology uses qualitative analysis in order to determine the adequacy of current security and how this can be applied to the civilian use of UAVs. The findings behind this research were that the civil GPS signals are the main concern with regards to civil UAV security. This research recommends using ways used in order to have a more secure GPS signal many of which come from current policies in place for military UAVs.

This 86-page book presents basic and advanced concepts in circuit dynamics - the circuit theory of frequency response, risetime, bandwidth, open-circuit time constants, Miller's frequency-dependent theorem, the Extra Element Theorem (EET), ZEET, Blackman's Z Theorem, the Cochrun-Grabel method for finding circuit poles, strategies for maximizing circuit performance involving stage isolation and pole separation, and the ability to analyze amplifiers by modularizing and controlling stage interfacing. It supplies derivations and more detail than the author's book, Transistor Amplifiers. It corrects some popular misconceptions about calculating bandwidth, fills in neglected high-frequenc ...

Ken Petersen, Adjunct Assistant Professor in the Geography Department of the University of Utah, in "Climate Change - Science and Sensibilities" provides a clear and simple description of the science (and lack there of) behind the current concern about greenhouse warming.

The function of cognitive communication is to enable people and machines to acquire knowledge. The gain in knowledge lies in the information gained from the signals received. Machine languages and natural languages spoken by people differ in that the signals of machine languages have sharply defined meanings, while the meanings of signals of natural languages are highly fuzzy. Werner Rupprecht explains how vague meanings arise in the brains of human beings, and that, paradoxically, owing to such vagueness, people are able to gain insights that machines cannot. He explains in detail the links between information theoretical entropy, thermodynamic entropy and energy, describes the sensory ...

Critical and Scientific thinking are often like Heaven: Everyone says they want to get there but few look forward to what it takes to get there. Critical-Scientific Thinking (C-ST) is a lot like that; everyone seems to think C-ST works in many cases, when we fly in an aircraft and arrive alive with or without our luggage, or when a prescribed medication works as predicted and intended. Critical-Scientific Thinking takes courage; it takes integrity; it takes guts to risk some of our most sacred icons or ideas or even whole belief systems, under serious siege from hard facts and truths, demanding we go back to the proverbial drawing boards. Further,C-ST may well threaten entrenched interes ...

PV/Wind/Diesel Hybrid Energy Systems are used for energy supply in remote areas. Depending on the geographical and meteorological situation as well as on the load profile specific hybrid energy system designs are the best and most cost efficient solution. Typically, these systems are used in regions where the costs for a grid connection are too high due to the remote necessaries. The advantage of these systems is that it is possible to design them very flexible and adjust them to the concrete demands. On the other hand, they represent a complex system thus requiring some effort in planning and design. The proposed system is intended to supply a small living complex in a remo ...
