Problem Set for Publishing with MATLAB

Write a script to plot function $y=\frac{\sin x}{x}$ for $\frac{\pi }{100}\le x\le 10\pi$ using increments of $\frac{\pi }{100}$ . Publish your m-file to html.

The m-file content: % This script plots a graph of Graph of y=sin(x)/x clc % Clear screenx = pi/100:pi/100:10*pi; % Create a row vector y = sin(x)./x; % Calculate y as function of xplot(x,y),title('Graph of y=sin(x)/x'),xlabel('x'),ylabel('y'),grid The html output:

A gas is expanded in an engine cylinder, following the law PV1.3=c. The initial pressure is 2550 kPa and the final pressure is 210 kPa. If the volume at the end of expansion is 0.75 m3, write a script to compute the work done by the gas and publish your solution to an html file. This is the same problem as this Problem you have solved before.

The m-file content: clc disp('A gas is expanded in an engine cylinder, following the law PV^1.3=c')disp('The initial pressure is 2550 kPa and the final pressure is 210 kPa.') disp('If the volume at the end of expansion is 0.75 m3,')disp('Compute the work done by the gas.') disp(' ') % Display blank linen=1.3; P_i=2550; % Initial pressureP_f=210; % Final pressure V_f=.75; % Final volumeV_i=(P_f*(V_f^n)/P_i)^(1/n); % Initial volume c=P_f*V_f^n;v=V_i:.001:V_f; % Creating a row vector for volume, v p=c./(v.^n); % Computing pressure for volumeWorkDone=trapz(v,p) % Integrating p*dv The html output:

A force F acting on a body at a distance s from a fixed point is given by $F=3s+\frac{1}{s^{2}}$ . Write a script to compute the work done when the body moves from the position where s=1 to that where s=10 and and publish your solution to an html file. Include a table of contents in the output file. This is the same problem as this Problem you have solved before.

The m-file content: %% Work done % This script computes the work done on an objectclc disp('A force F acting on a body at a distance s from a fixed point is given by')disp('F=3*s+(1/(s^2)) where s is the distance in meters') disp('Compute the total work done in moving')disp('From the position where s=1 to that where s=10.') disp(' ') % Display blank line%% Create a row vector for distance, s s=1:.001:10;%% Compute Force for s F=3.*s+(1./(s.^2)); % Computing Force for s%% Integrating F*ds over 1 to 10 meters. WorkDone=trapz(s,F) The html output:

what is variations in raman spectra for nanomaterials
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think
Professor
what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
How we are making nano material?
what is a peer
What is meant by 'nano scale'?
What is STMs full form?
LITNING
scanning tunneling microscope
Sahil
how nano science is used for hydrophobicity
Santosh
Do u think that Graphene and Fullrene fiber can be used to make Air Plane body structure the lightest and strongest. Rafiq
Rafiq
what is differents between GO and RGO?
Mahi
what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
Damian
Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
Joe
anyone know any internet site where one can find nanotechnology papers?
research.net
kanaga
sciencedirect big data base
Ernesto
Introduction about quantum dots in nanotechnology
what does nano mean?
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?
absolutely yes
Daniel
how did you get the value of 2000N.What calculations are needed to arrive at it
