Hello, Welcome to my final year project page.

Am Namusobya Joy Sophia 12/U/11674/PS one of the members of BSE Pursuing a bachelor’s degree in software engineering.

For one to complete and be awarded a degree in software engineering,  

One of the requirements is coming up with a complete final year project.

I will share what we as a group have done and particularly what I have done towards the completion of the project. 

      CONCEPT PAPER 

We met as a group at the beginning of the semester to brainstorm through all possible ideas that we are   to work on and every one presented a different idea.

After presenting several ideas. We decided to take up E-coli bacteria detection system .The automated E.coli bacteria detector system covers a geographical area spanning community centers and other areas where there is need for full water safety or where there is need to improve critical water treatment systems. 

The system   detects methane gas that indicates the presence of E-coli bacteria. The system is meant to measure gas levels and concentration in water and thereafter relay the information to the user to warn them.  We were sure of where to obtain firsthand information on which we could base to analyze the depth and effect of the problem.

We had a better understanding of the problem we knew we would be able to clearly to solve it.

We started working on the concept paper which was approved by our supervisor.

 PROPOSAL WRITING

With the proposal I   majorly did the literature review and system objectives as below,

E. coli can cause diarrhea, urinary tract infections, respiratory illness, and bloodstream infections.  Other kinds of E. coli are used as markers for water contamination. E. coli being found in contaminated drinking water with faecal contamination

The symptoms of E.coli infections include severe stomach cramps, diarrhea (often bloody), and vomiting and fever. These are serious or even life-threatening

The main objective is to develop a system that shall detect the presence of Escherichia Coli bacteria in water using methane gas as an indicator that is given off by contaminated water either by animal waste or human waste. .And there after send notifications to the mobile user using a GSM Module. The system user will be able to know whether water is safe for use or not

I reviewed related systems and critically analyzed their weaknesses and strengths and found out why these systems are not widely used at the moment. System examples include,

 Automated Microfiltration to Purify GFP-His was developed to detect the presence E.coli bacteria in contaminated water However the system was scientific and required a lot of scientific knowledge and was time consuming and required a lot of labor.

Another system was a biosensor system was developed to detect bacterial concentration in products so that it does not exceeds the limits allowed by the law. The system was dedicated to measuring the sample electrical characteristics,

The biosensor system bacterial concentration detection based on the technology requires no particular knowledge of microbiological techniques. It was suitable for microbial screening in industrial and commercial environments. However this method was slow and expensive.

 The existing systems that detect E.coli bacteria are not mobile and they are expensive to use hence less efficient.

REQUIREMENTS DOCUMENT WRITING

I designed the interview questions with a special focus on the different stakeholders like Individual end users, Health centers, National water Sewage Corporation involved at every stage of water consumption so as to find valuable amounts of data that we could base on to find the effect of this bacteria. I also did the citations as a conclusion to the document.

REPORT 

 In the report I did section 4 of the report that majorly deals with the thorough testing of the system before installation. Inspections where carried out on code and reports to ensure that good programming practices are followed.  I framed a test plan and executed to monitor the performance of the system.

Secondly, the test objectives were defined in detail. Thereafter the safety measures to be followed while using the system and limitations to the system performance I defined therein.

CONCLUSION
