CFD Study and Investigation of the Critical Ratio for Pressure-Head Ratio inside Drainage Manholes
Get PDFThe objective of this research is to study the pressure-head rising inside a manhole in pipelines, in relationship with the ratio from manhole diameters to its pipes diameters. The research team adopted CFD to simulate the manhole flows, at different conditions of varying inlet and outlet pipes diameter and manhole diameters. The risk of manhole overflow can also be reduced by controlling how fast is the rate of pressure-head rise per given flow rate. To reduce the peak and rate of rising of pressure-head column inside the manhole to be attained, the ratio between manhole widths (diameter) to its pipe diameter should be taken into considerations. Based on CFD analysis it is found that ratios less than 3 are shown to have better results, producing lower peak values of pressure-head to be attained inside manholes

Agro - Meteorological data Collection using a LoRaWAN - Based IoT Sensor Network
Get PDFGenerally, the variation of meteorological conditions has a significant influence on the agriculture sector in general. In Tanzania, the study conducted in 2015 found most of the existing automatic meteorological stations are not working, and the surveyed manual meteorological stations record meteorological data in the cards daily, but cards are sent in a month to month time interval to the respective organs, this makes the concept of early warning difficulty. Therefore having near real-time meteorological data will enable the crop monitoring and forecasting systems to monitor crop development and provide early warning to the farmers and the government.
The advancement of the Internet of Things (IoT) offers possibilities for developing an integrated sensors network to collect meteorological data on a near-real-time basis. In this study, the developed integrated sensor network includes sensors, which record remote meteorological data such as rainfall, humidity and temperature, a communication network, and a web application that enhance data visualization in both graphical and tabular format. In the communication system, the LoRa technology was used, which is more preferable compared to other Low Power Wide Area Network (LPWAN) technologies such as NB-IoT and Sigfox for this application. The developed system uses the LoRa Gateway Operating system which provides capabilities to build a private network, and make it more cost-efficient by reducing the operation cost for account subscription, in online platforms such as The Things Network (TTN), ThingPark, ThingSpeak, and Loriot to avoid free accounts limitations. Moreover, the developed system can work in remote areas with limited Internet access as the meteorological stations can communicate with the gateway at a distance of up to 25 km.

The developed prototype application produced a number of results including live monitoring of temperature, humidity, CO2, CO, Smoke, and many others. A system evaluation process was conducted and the result indicated 99.999% accuracy levels. The results, it evidence that the developed prototype application can improve environmental security in Industrial IoT CI institutions
Determinants of the Rate of Procurement Practices on Disposal of Assets in Kenya's Public Sector: A Case of the Judiciary
Get PDFDisposal of unwanted assets to the Public is an important aspect of procurement and store management in many organizations. When equipment is in surplus or obsolete, keeping it through maintenance, parking, insurance or storage may lead to exceeding the recoverable amount which can be the result of continued use of the equipment. In Kenya, the public sector has certain disposal guidelines and procedures as stated in the Public Procurement and Disposal Act, 2005, and the Public Procurement and Disposal Regulations, 2006. The PPDA applies to all procurement of works, goods, and services, and also, the disposal of assets by all public entities. Disposal of assets in the Public sector is complex due to the multiple interests from various stakeholders against a backdrop of the objectives it tries to achieve amidst various regulatory bodies or policies which are supposed to be observed. The main goal of this research was to make an assessment on the determinants of the rate of procurement and disposal of the assets in Kenya’s public institutions, a case of the Judiciary. However, the objectives were used in determining the influence of procurement planning on the disposal of assets; determine how accounting and financial risks affect the disposal of the assets, and identifying the effects of the management methods chosen on the rate of disposal of assets. The study adopted a descriptive study design with a case-study approach to the Judiciary. For purposes of this study, the population of interest was 101 respondents from the Judiciary, which included the department heads, deputies, the disposal committees, and procurement and disposal staff. The study adopted a census sampling technique. The collection of primary data was done using a questionnaire research method The findings show that procurement planning, financial and accounting risks, and choice of management methods affected the rate of assets disposal in the Judiciary to a large extent, It also revealed issues such as corruption, political interference, non-adherence to the PPDA provisions, and PPOA inefficiency as impediments to assets disposal effectiveness and further the study also revealed that the legal framework and regulations had an impact on the relationship between determinants of the rate of procurement and disposal of the assets. The study recommended that The Judiciary’s procurement department should consider scaling up efforts and work with diligence in stemming out corrupt officers, and ensure total adherence to set PPDA procedures; include strict disposal procurement planning and adopt the well-researched choice of management methods; allocate resources for update training to the procurement and finance staff, and properly explain stakeholders’ limits and roles when dealing with assets disposal and adopt a proactive and stringent approach
