Control optimisation. It is example of use BFGS algorithm to control satellite form Earth atmosphere to the Mars. Controled is engine power (bang-bang type) and angle of nozze.
Metric Converter is an useful tool for metric conversion, weight conversion, area conversion, mass conversion, angle conversion or any other unit conversions performed by, well, all. :)
This function is used to evaluate the max height and the max
distance of a projectile and plot the trajectory.
Inputs
v0 : The initial velocity in m/s
theta: The angle at which the projectile is fired in degrees
Outputs
hmax : The maximum hieght in m
dmax : The maximum distance in m
It’s your first day in the lab.Undoubtedly you are experiencing a range
of emotions: excitement, curiosity, anxiety. You will be working in
this lab and with a group of people, as well as with your supervisor,
for several years to come. This is the first day of a long commitment
and, for some, a hard road ahead. Which is why it’s important to get
off on the right foot.
n the first part of this book, we give an introduction to the basic applications of wireless com-
munications, as well as the technical problems inherent in this communication paradigm. After a
brief history of wireless, Chapter 1 describes the different types of wireless services, and works
out their fundamental differences. The subsequent Section 1.3 looks at the same problem from
a different angle: what data rates, ranges, etc., occur in practical systems, and especially, what
combination of performance measures are demanded (e.g., what data rates need to be transmitted
over short distances; what data rates are required over long distances?) Chapter 2 then describes
the technical challenges of communicating without wires, putting special emphasis on fading and
co-channel interference. Chapter 3 describes the most elementary problem of designing a wireless
system, namely to set up a link budget in either a noise-limited or an interference-limited system.
After studying this part of the book, the reader should have an overview of different types of
wireless services, and understand the technical challenges involved in each of them. The solutions
to those challenges are described in the later parts of this book.
InGaAs/AlGaAs semiconductor lasers come in threetypes: VCSELs and two types of EELs. The VCSEL, asits name implies, emits vertically, normal to the planeof the device, owing to cavity mirrors grown withinthe epitaxial material itself. The VCSEL’s circular beamhas a numerical aperture (NA) of roughly 0.2, or a fullangle of approximately 25 degrees.
