The Global Positioning System(GPS) is a satellite-based navigation system
that was developed by the U.S. Department of Defense (DoD) in the early
1970s. Initially, GPS was developed as a military system to fulfill U.S. mili-
tary needs. However, it was later made available to civilians, and is now a
dual-use systemthat can be accessed by bothmilitary and civilian users .
GPS Errors and Biases
GPS pseudorange và vận chuyển pha đo được cả hai bị ảnh hưởng bởi một số dạng sai sót ngẫu nhiên và những thành kiến (lỗi hệ thống). Những lỗi này có thể được phân loại như những người có nguồn gốc ở các vệ tinh, những người có nguồn gốc ở người nhận, và những người được do để tuyên truyền tín hiệu (khúc xạ khí quyển) . Hình 3.1 cho thấy các lỗi khác nhau và những thành kiến.
Most of the chapters in this volume were presented as papers at a small
research conference held in 2001 at the Kellogg School of Management
of Northwestern University in Evanston, Illinois. The purpose of this conference
was to explore new ideas about the psychology of leadership, an
important and long-enduring research topic within the field of social psychology.
It was the opinion of the editors of this book and the conveners
of the conference that the social psychological study of leadership had

Amos Tversky, a Stanford University psychologist and a founding father of
behavioral economics, liked to say, “My colleagues, they study artifi cial
intelligence. Me? I study natural stupid

• A diode is a very useful non-linear device • It allows current to flow in one direction and prevents it flowing in the other
• When a positive voltage is applied across the diode then current will flow • The diode is said to be forward biased • When a negative voltage is applied then the diode is reverse biased and no current will flow
Diode Characteristic Curve
Forward Biased Diode
• A positive voltage is applied to circuit so current will flow • Diode effectively behaves like a short circuit when forward biased...

The argument, as given, is weakened by the fact that it does not address any counterarguments or note any other perspectives. It could have addressed the positive role models many athletes play to youth, the community outreach many professional athletes do for free, or the generous charities many athletes set up and donate money to.
