    ScenarioLSB has recently leased a new building in Stratford to provide teaching for potential stu- dents in that area and its surrounding. The building will house some offices, classrooms, a reception and computer labs. The building will not contain administrative offices as adminis- trative staff will be located in the other campus and they will work remotely.LSB recruited you a network consultant who will be designing, building and implementing LSB’s LAN. LSBM emphasised that their budget is quite tight and you will have to work around this but still be able to provide the best provide the best network this budget can get.LSB provided the following specifications for their new network in Stratford:The new building comprises of four floors. Each floor will be used for a certain purpose and will need specific requirements for technology devices and equipment as below:The ground floor will house the students lobby, secretary office and admission officer office and will need to have the following equipment:• Wi-Fi to enable students to use the internet while sitting in the lobby• Admission officer need to have one PC and one printer.• Secretary need to have one PC and one printer/photocopierSecond floor will have three labs for classes and a study room. Equipment required are as be- low:Each of Three labs each should contain:o25 PC for students. o1 PC for instructor. o1 projector.o All PC needs to be connected to the internal network.o Each lab should have a server in the closed located inside the lab.o One of the three labs should contain a Linux/mysql/php server.• A study room should containo 10 PCs for students to use to do their homework/research and a printerThird floor contains six classrooms and each should contain:•A PC for each class for the instructor connected to the internal network and to the in- ternet.• A projector.Fourth floor is divided into eight offices for lecturers and a meeting room. . Equipment re- quired are as below:• Each Lecturer office should have:o A PC in each office connected to the networko Each pc should also be connected to the interneto One printer/photocopier in the hall for all lecturers to use.• The meeting room should have:o 1 projectoro6 network sockets to enable staff to connect to internal network/internet while in meetingsThe main server for the network will be installed in a server room on the ground floor. Your ISP has given you a ‘210.150.10.17’ IP for your company. You will need to divideyour network into various sub networks to allow different functions to operate in various de- partments as below:• Each of the Computer labs should be on its own sub network.•Only one Computer lab should have limited access to the internet for educational purposes.•The secretary, the admission officer, meeting room, lectures and all printers should be on the same sub network.•Students study room and the Wi-Fi in the lobby should be on the same sub network with a lot of restrictions their use of the Internet. Internet should only be used for ed- ucational purposes. All other web applications on this sub network should be disa- bled. E.g. chatting, Facebook and so on.The main server located on the ground floor should be a powerful server.LSB also wants to have a network management solution to enable all staff to log in to theirPC.The main server should have a mirror server in case anything goes wrong for backup purpos- es.Each of the servers in the labs should only by accessible by computers inside the lab for edu- cational and security purposes and to avoid students hampering with the main server data. Only staff and lecturers will be able to use printers. And the network management solution should be able to provide this (username and password).Assume that you have been appointed as Network Consultant to this company and you are required to design the LAN in simulated environment.

    Hi. I need some help with my project. Money is not the problem, but I need someone really expert in Matlab Simulink who will help me to finish this project. Of course I will help and follow your work day by day and explain you everything you don"t understand. It will be a very long work (I think) but I"ll pay very well.The project consists in a simulation in Simulink of a high speed communication using the MIMO technique in addition to multichannel frequency multiplexing. I"ve attached an important paper that you have to read about multichannel frequency multiplexing. VERY IMPORTANTIn practice I want to simulate the system presented and make it better by using MIMO combined to it!!!The goal is to have a running simulation with BER nearly 0. You have to modify the simulation I"ve started and make it work!This are the datas of the problem:- the transmission is LOS and the frequency bands are the 2 slots [81-86 GHz] and [94.1-100 GHz].- Multichannel frequency division multiplexing and LDPC codes are used.- the modulation used is a 64-QAM with raised cosine transmit filter (rolloff = 0.25).- the spectral efficency is 4,8 bps/Hz (E=k/1+rolloff) where k=log2(64)=6- the transmission distance is 100m- the antenna gains are respectively 24dBi in transmission (horn antennas) and 40dBi rx (cassegrainian antennas).- atmospheric attenuation -> ITU models -> 20dB for 99% reliability- the receiver figure is 6dB- the maximum transmission power is 100mW (20dBm)All this date are necessary to calculate the link budget (already done), I can provide the calcs and I"m happy if you can provide yours in order to verify!My calcs report that the transmission is possible with Eb/No= 19dB and a BER= 10^-5The boost in the bitrate is obtained with MIMO techniques, in particular with a 4x4 configuration and spatial multiplexing.This means that the source stream is divided into 4 different streams transmitted by 4 different antennas. Each rx antenna is receiving all the transmission, so we need to implement an alghoritm to separate and receive the different streams. This is the real problem. The algorithm must be written in Matlab. An example is the V-Blast algorithm that I attached.STRUCTURE OF THE SIMULATIONAttached you can find the beginning of my simulation. It"s just a start and the MIMO algorithm is not implemented. At this point every rx antenna receives only one stream. Of course only 2 trasmitters are present and not 4!I"m asking you to upgrade this simulation as requested.You have to run the parameters initialization file first (.m file).Structure of the requested simulationThe unique bit source is divided into 16 different streams (in the simulation we have just 2 and with 2 different sources). Each stream is LDPC coded. The LDPC simulink block has the DVBS2 parity check matrix (32400x64800) as a parameter which has a coderate of 1/2.Each stream goes through a 64-QAM modulation and a raised cosine transmit filter. After that (IMPORTANT POINT) the signals are upconverted at an intermediate frequency (ex. 2GHz) in adjacent bands occupying 560MHz each as in the paper that I attached (Improved Spectral Efficiency...).After that the signals are grouped in groups of 4 by a combiner becoming 4 signals (each one composed by 4 adjacent signals). At this point we"ve the final 4 upconversions (all at the same frequency) in order to fit the 2 bandwith slots [81-86 GHz] and [94.1-100 GHz]. In this way all the 4 antennas transmit at the same frequency and MIMO can be used.The rx chain is the inverse of the transmission one, but as I said, an algotithm for the 4x4 MIMO detection must be implemented. All the rx antennas must rx all 4 transmissions and separate it!After that we have to consider other interference problems and add it to our simulation, such as phase noise.If you think you are able to help me doing the whole work or just for the 4x4 MIMO algorithm, contact me.You also have to explain me your work!

    This is an IEEE paper. Very recent one. We require this to be implemented not just with usual image processing techniques but new functions should also be implemented and tried.The abstract is as followsIn medical image processing, low contrast image analysis is a challenging problem. Low contrast digital images reduce the ability of observer in analyzing the image. Histogram based techniques are used to enhance contrast of all type of medical images. They are mainly used for all type of medical images such as for Mias-mammogram images, these methods are used to find exact locations of cancerous regions and for low-dose CT images, these methods are used to intensify tiny anatomies like vessels,lungs nodules, airways and pulmonary fissures. The most effective method used for contrastenhancement is Histogram Equalization (HE). Here we propose a new method named “Modified Histogram Based Contrast Enhancement using Homomorphic Filtering” (MH-FIL) for medical images. This method uses two step processing, in first step global contrast of image is enhanced using histogram modification followed by histogram equalization and then in second step homomorphic filtering is used for image sharpening, this filtering if followed by image normalization. To evaluate the effectiveness of our method we choose two widely used metrics Absolute Mean Brightness Error (AMBE) and Entropy. Based on results of these two metrics this algorithm is proved as a flexible and effective way for medical image enhancement and can be used as a pre-processing step for medical image understanding and analysis.

    I have a set of 14 nonlinear equations to solve. I used lsqnonlin to solve them but I am failing in making it converge. This can be attributed to the large difference in value among the 14 unknowns. The solution can range from 1e-10 to 1 across the 14 parameters. I tried all tricks I know to overcome this problem but failed. You are free to use a different solver, write your own solver or normalize the equations in the way you like. The main code is a bit ling but you shouldn"t care about it. All what you need to care about is the 14 equations at the end of the TRIAL_7 code and the caller subroutine for solving the equations. I attached also an excel sheet you approximate values of what some of 14 unknowns should be. These are just approximates of the solution. We can try solving the provided example and if we succeeded then we can try different examples to make sure that the code works. Please check the codes and try playing around with it before bidding. I will happy to provide any extra details and clarifications once needed.

    Dear FreelancerI have the following Problem. I started with a list of companies and created two files, one containing the returns for the companies and the other one corporate informations. In a final step i now want to make a multiple linear regression of this two files. The problem is that by calculating and sorting out the data, the one data string is approximatly 2100 observations and the other one 2500 even though i started with the same amount of information (companies). So somewhere in my code there must be a fault/ this code is not working for this data. I can think as a possilbe problem that i use the unique function once which might leeds to problems but im not sure where the fault is. If someone finds the problem in the code i would be able to pay up to 30 dollars. I don"t think its a big deal if you are good in matlab.For further discussion please contact me. Also for the files. Thanks
