Assignment Description

Automatic Detection Algorithm of events (signals) in HRV Data using MATLAB 

There are two frequency which are Low Frequency(LF) and High Frequency(HF) that been used in this project. The LFHF.m and HRV data are attached together as a reference. 

1)      By using acceleration data (XAcceleration, YAcceleration,ZAcceleration) , determine the ‘resting’ time to detect the events in LF and HF signals. The ‘resting’ time should be equal to resting time where there is no physical activity occurred at that time. The acceleration must be divided into 2 regions which are the ‘active’ time and the ‘resting’ time.  This region must be identified by using filtering (e.g: low/high pass filter) to make the detection signal looks more accurately. Use FFT first to find the frequency for the filtering process. 

2)      After the ‘active’ and ‘resting’ time is identified, draw a subplot of 3 signals (LF,HF,Acceleration done with filtering process). 

3)      During length of ‘resting’ time regions, put a horizontal line as a threshold value (the threshold line can obtain from the value of mean along one period of ‘resting’ time) for every LF and HF. Note: the threshold line must be draw for every ‘resting’ time condition of the acceleration signal. The value of threshold line is depending on the number of peaks of the signal within one ‘resting’ time signal. It may different from each other depending on the signal.

4)      For HF and LF signal, calculate the width between one peak to other peak that are above the threshold value. Note: Put an indication marks of every width of each of the signal. 

5)      The value of width, mean,standard deviation and area of the peaks for Low Frequency(LF) and high frequency(HF) in ‘resting’ time signal in acceleration should be appear in notepad. Note: Please put a numbering for ‘resting’ time signal for all the data in notepad. For example, it may contain more than one ‘resting’ time in the signal. For the first ‘resting’ time signal, it is necessary to put “Rest Time Signal 1” and so on. 





Example of the signal Script function for calling HFLF.m file:

[LF, HF, LFHF, filterorder, f_low, f_high, W_low, W_high] = Get_LFHF(HRVDatams);


Frequently Asked Questions

Is it free to get my assignment evaluated?

Yes. No hidden fees. You pay for the solution only, and all the explanations about how to run it are included in the price. It takes up to 24 hours to get a quote from an expert. In some cases, we can help you faster if an expert is available, but you should always order in advance to avoid the risks. You can place a new order here.

How much does it cost?

The cost depends on many factors: how far away the deadline is, how hard/big the task is, if it is code only or a report, etc. We try to give rough estimates here, but it is just for orientation (in USD):

Regular homework$20 - $150
Advanced homework$100 - $300
Group project or a report$200 - $500
Mid-term or final project$200 - $800
Live exam help$100 - $300
Full thesis$1000 - $3000

How do I pay?

Credit card or PayPal. You don't need to create/have a Payal account in order to pay by a credit card. Paypal offers you "buyer's protection" in case of any issues.

Why do I need to pay in advance?

We have no way to request money after we send you the solution. PayPal works as a middleman, which protects you in case of any disputes, so you should feel safe paying using PayPal.

Do you do essays?

No, unless it is a data analysis essay or report. This is because essays are very personal and it is easy to see when they are written by another person. This is not the case with math and programming.

Why there are no discounts?

It is because we don't want to lie - in such services no discount can be set in advance because we set the price knowing that there is a discount. For example, if we wanted to ask for $100, we could tell that the price is $200 and because you are special, we can do a 50% discount. It is the way all scam websites operate. We set honest prices instead, so there is no need for fake discounts.

Do you do live tutoring?

No, it is simply not how we operate. How often do you meet a great programmer who is also a great speaker? Rarely. It is why we encourage our experts to write down explanations instead of having a live call. It is often enough to get you started - analyzing and running the solutions is a big part of learning.

What happens if I am not satisfied with the solution?

Another expert will review the task, and if your claim is reasonable - we refund the payment and often block the freelancer from our platform. Because we are so harsh with our experts - the ones working with us are very trustworthy to deliver high-quality assignment solutions on time.
