I have attached an article that captures exactly what I want. All the coding must be in MAtlab (a) Generate figure 1(a) The wave number curves 1) Generate Fig. 1b : Phase and group velocity 3) generate attenuation coefficient Fig.1c 4) Generate the propagated wave in 1d. 5)Briefly summarize how the figures are generated and make reference to the equations or method used in the paper if there is need for that 5) You should attach the Matlab code and MS word containing the figures with explanation of how the figures are generated. t.

Looking to create a prototype for a Bluetooth based device that can be remotely controlled from a mobile app. You'll need to have a proven experience of creating a low voltage devices, be comfortable designing circuit boards and creating a prototype. Big plus if you created a similar integration between IoT (Internet of Things) and mobile apps. You will not need to create the mobile app but you'll need to work with the rest of the team to enable the platform which the will run the firmware. Do you enjoy working with Microcontrollers such as Arduino or Raspberry Pie? Then this project might be of interest to you.

Need experienced micro-controller programmer to program a small devise to recognize a repeated 8-12 hertz signal from an air pressure transducer. Understand that piezoelectric transducers do not work well as such low frequencies. Could use advice on perhaps another kind of transducer. Engineer can also decide which micro-controller would be best for the job. Device operates in a noisy environment. On recognition of target vibrations, device sends radio signal to cell phone(s) and/or computers within 30 feet.

Digital signal processing job written in EcmaScript 2016 We have a raw sensor reading where we need to remove extreme values and afterwards find peaks (both highs and lows) and count them. Requirements: Time is in seconds, resolution in 20Hz. The Time Between Peaks should be a variable (Tbp) The time between a top peaks start and finish to count as a toppeak should be a variable (Ttut) The time between groups of peaks should be a variable (Ts) Y values below Yl should be excluded Y values above Yh should be excluded Peaks should have at least Pm between a bottom and top. The result must be written in EcmaScript 2016/JavaScript The result should be in JSON and follow the example analysis results. We have created a zip file with data, imagery and two analysis for this job. Have a look at analysis01.png. The result would be one group with 10 peaks. See analysis01.json. Data is in data01.json. The project is considered completed once we can call node run.js data01.json params.json > result01.json node run.js data02.json params.json > result02.json See parameters.json in the corresponding example zip file. And the resulting json file matches our. (minor rounding differences are acceptable) We have also included data03.json and data04.json for additional data examples. If you require using existing libraries then they should be defined in a package.json file and we should be able to run npm install in a clean environment to get up and running. If any questions then please ask. The programming language is not up for debate.
