Preface
Programming in Java doesn't have to be dull and boring. In fact, it's
possible to have a lot of fun while programming in Java. This module is onein a series that concentrates on having fun while programming in Java.
Viewing tip
I recommend that you open another copy of this module in a separate
browser window and use the following links to easily find and view the Figureswhile you are reading about them.
Multiplyadd operations
This module deals with a topic commonly know as Digital Signal Processing,
(DSP for short) .
Computational requirements for DSP
The computational requirements for implementing DSP in a computer program are
usually straightforward. Almost all DSP operations consist of multiplyingcorresponding values contained in two numeric series and then calculating the
sum of the products. Sometimes, the final sum is divided by the total number ofvalues included in the sum to produce an average. This is often referred to as a
sumofproducts or
multiplyadd operation .
(This is the digital equivalent of integrating the product of two
continuous functions between specified limits.)
Typical notation
Such an operation can be indicated by the symbolic notation shown in
Figure 1
(where the strange looking thing constructed of straight lines is the Greek
letter sigma) .
Questions & Answers
Introduction about quantum dots in nanotechnology
nano basically means 10^(9). nanometer is a unit to measure length.
Bharti
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
how to know photocatalytic properties of tio2 nanoparticles...what to do now
it is a goid question and i want to know the answer as well
Maciej
characteristics of micro business
Abigail
for teaching engĺish at school how nano technology help us
Anassong
Do somebody tell me a best nano engineering book for beginners?
there is no specific books for beginners but there is book called principle of nanotechnology
NANO
what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
so some one know about replacing silicon atom with phosphorous in semiconductors device?
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Harper
Do you know which machine is used to that process?
s.
how to fabricate graphene ink ?
for screen printed electrodes ?
SUYASH
What is lattice structure?
of graphene you mean?
Ebrahim
Graphene has a hexagonal structure
