    A Plasma glucose prediction tool based on dietary assessment: a case of type 2 diabetes patient
    (Strathmore University, 2018) Njihia, Alex Wainaina
    Management and control of blood sugar using dietary intervention has for a long time been considered to be important. The caregivers have always advised diabetic patients to moderate the amount of carbohydrates intake. The approach here has always been reduction in the amount of carbohydrates, unfortunately this does not translate to the reduction on the blood sugar in some case. This is explained by the fact that what determines the sugar levels in the blood has to do more with the glycemic load of the carbohydrates consumed which is dependent on the glycemic index of the food item consumed. Though the amount of carbohydrates taken by the patient has a role to play, it is rather indirect. The study, sought to develop a tool for the computation of the glycemic load of the food item consumed by an individual by aggregating the various meals parameters. The tool has been developed by analyzing the dietary factors that affect the glycemic load and using these factors has the regressing variables. The algorithms used in the development of the dietary assessment tool have been used to map and mine the standard glycemic index of individual food item and to estimate individual patient meal item glycemic using regression analysis approach. Experimental data results indicate the tool can compute the glycemic load of the food item which is comparable to the standard glycemic load values and it also gives plasma glucose prediction trajectories which mirrors those obtained from existing clinical trial dataset.

    A Real-time location based algorithm for notification of crime hot-spots using crowd sourcing
    (Strathmore University, 2018) Chepngetich, Maryline
    Security of the people has always been the number one objective of many governments in the world today. Governments endeavour to achieve this objective has faced several challenges ranging from economic, social and political. Despite heavy investments by local and National Government in Kenya on security measures, crime continues to remain a serious problem in the society, as a result, there are loss of lives, loss of property and investors shying away. Gathering relevant and up to date operational information on crime intelligence across several sources has always been one of the challenging issues faced by national security practitioners and citizens. This therefore makes it difficult to identify crime hotspot areas in timely manner, and also improper allocation of Police resources in the right hotspot areas. The data collection exercise was done earnestly to ensure that there was ample understanding of the participants’ interaction with crowdsourcing platforms and their experience and willingness to use a crowd-based crime hotspot reporting network. The study thus found significant justification for the design of the criminal hotspot system to leverage data about crime incidents in the city in order to classify crime hotspots. The design of the system was made using unified modelling language and detailed in the fifth chapter of the thesis. The developed prototype was then tested against parameters to gauge its efficiency and effectiveness. The conclusions of the testing as well as the recommendations of the study are documented in the sixth and last chapter of the study respectively.

    Cloud based prototype for electronic tea auctioning: case of Momul tea factory
    (Strathmore University, 2018) Chepkwony, Irine Cherotich
    Kenya is among the global leaders in tea exports. Tea sub-sector is among the largest foreign exchange earners in the county. Processed tea is sold through the Mombasa tea auction; each tea factory is represented by a broker. The method of auction is “open cry “; all buyers and sellers meet and compete for tea sales and purchases publicly; the prices and awards are also public. The auction processes are currently done manually and the auction model is broker centric. There have been serious challenges affecting the Mombasa auction house; inefficiency in the manual processes, lack of transparency to all stakeholders and concerns of unfair auctions practices of collusions and price manipulation. The aim of this research was to remodel tea auction using information technology innovation as an agent of that change. The remodelling involves devolving tea auctions so that the tea processing factories can auction their own tea directly to the buyers. This is achieved through the use of a cloud-based e-auctioning prototype. By enabling factories auction their own processed tea, it resolves the issues of transparently, collusions and price manipulations and it indirectly reduces the cost of production through minimal dependence on brokers for tea auctions thus positive impact on raising the overall income. The research design used is a mixed method research design; qualitative and quantitative, information was collected from written literature; raw data were collected from the population of the case study: Momul tea factory limited by means of interviews and questionnaires and were analysed using SPSS. The analysis results were presented in form graphs of which over 80% of the respondents felt that brokers controlling the auction process were the main challenge ailing tea auction in Kenya. The tools used to develop the prototype are: MySQL, PHP, HTML and JavaScript, these are open source programming tools. Usability tests were carried out among the selected users. The overall reception of the concept was positive with recommendations to include more factories and tea trade regulatory bodies.

    MPLS (Multi-Protocol Label Switching) assisted routing procedure in Software Defined Networking (SDN)
    (Strathmore University, 2018) Otieno, Humphrey Owuor
    Multi-protocol label switching has been incorporated into provider networks to provide quality of service. Owing to the design of the protocol, its ability to push and pop labels in packets, independent of their underlying protocol makes it popular in interconnecting multiple networks in to one transport pipeline. At the same time, multi-protocol label switching has proven to be a very fast procedure for forwarding devices because the central processing unit cycles required in making a forwarding decision is far less compared to traditional forwarding decision-making metrics like analyzing the internet protocol header. However, current multi-protocol label switching implementation is a complex configuration procedure and does not provide a central bird’s eye view of the network topology to network engineers. Logging in to every label switching router and loading multi-protocol label switching configurations to allow it to connect to neighboring label switching routers in the label switching path is required. Allowing network engineers to have a central view and control of the network topology while still providing multi-protocol label switching services in a simplistic approach will make them achieve adaptive routing and traffic engineering seamlessly. This will improve quality of service and quality of experience in transport networks. Software defined networking is the approach this research takes towards providing central control because of the flexibility, programmability, and adaptability of the technology. This work proposed the design of a routing procedure that will implement multi-protocol label switching on a software defined network via OpenFlow. Experimental synthesis and prototyping approach was used to achieve the research objectives. A simulated environment called Mininet provided the implementation test bed. Internet control message packets were the test data to show how multi-protocol label switching labels are added and stripped. An illustration of the packet capture information from the experiment was presented and analyzed.

    Mobile application for filing of and payment for Intellectual Property Rights using QR code: case of Kenya industrial property institute
    (Strathmore University, 2018) Andati, Eric Maloba
    Ensuring secure transmission of sensitive data and payment of transaction fees has been one of the challenges affecting customers and businesses. Intellectual Property (IP) field is one such area that has faced such challenge. Over the years, IP has grown in importance, attracting greater interest and increased need by inventors and other IP rights holders to seek protection of their inventions and other IP rights. To ensure protection of these rights, applicants are required to file their applications at IP offices and remit various fees during the examination process, as well as pay annual maintenance fee for the protection to remain valid. While filing for IP rights, applicants face security challenge, as their IP data can be intercepted while in transit or be exposed to third parties thus compromising their inventions. In addition, while making payment of IP fees, they face challenges such as delayed transactions and platform incompatibility. On the other hand, IP offices are susceptible to loss of revenue as a result of less-than-secure payment methods used. Hence, this study aimed at establishing how proximity/contactless technology could be incorporated into mobile-based devices to support secure mobile filing of and payment systems for IP rights. This research therefore proposed a process to develop a QR code-based mobile application that would facilitate speedy and secure filing and transmission of IP data as well as settlement of payments by IP rights holders to IP offices. Consequently, a functional mobile application that can generate a QR code, post the same to a remote server and make payment by scanning a QR code is presented. Additionally, a simple web page is provided to present the submitted information which has been encoded in QR format. Data collection was achieved by means of questionnaires and review of secondary data sources. The study was conducted in line with ethical practices as specified by the University rules and regulations.
