    Designing of UHF- Radio Frequency Identification (RFID) Antenna
    (IJSER, 2013-11) Swagarya, Godbless; Boaz, Lawrence; Kisangiri, Michael
    Radio frequency identification (RFID) as a rapid developing automatic wireless data collection technology, set interest for industrials and government applications. The demand on the automated supply chain and logistics has been pervasive, aiming to replace the tedious bar-code labeling, and has driven an increasing number of research activities on the RFID as alternative solution. Regardless of the type, all RFID tags have two main components: an antenna which transmits and receives data and an integrated circuit (IC) called transponder that handles the data processing, data storing and signal modulating. This paper gives an insight look on RFID technology, concept theory for passive RFID antenna, impedance matching, and antenna size reduction techniques. The designing and simulation for passive UHF-RFID antenna is presented.

    An overview of pipeline leak detection and location systems
    (Pan African International Conference on Information Science, Computing and Telecommunications, 2014-07) Boaz, Lawrence; Kaijage, Shubi; Sinde, Ramadhani
    Leak detection in transmission pipelines is crucially important for safe operation. Delay in detecting leaks leads to loss of property and human life in fire hazards and loss of valuable material. Leaking of methane and hydrocarbon gas causes negative impacts on the eco system such as global warming and air pollution. Pipeline leak detection systems play a key role in minimization of the probability of occurrence of leaks and hence their impacts. Today there are many available technologies in the domain of leak detection. This paper provides an overview on external and internal leak detection and location systems and a summary of comparison regarding performance of each system.

    Wireless Sensor Node for Gas Pipeline Leak Detection and Location
    (International Journal of Computer Applications, 2014-08) Boaz, Lawrence; Kaijage, Shubi; Sinde, Ramadhani
    Many different wireless sensor nodes for gas pipeline leak detection and location has been proposed but still there are challenges particularly on environmental issues and signal accuracy. This paper discusses theories and environmental constraints for wireless sensor nodes, a case study of Dar es Salaam - Tanzania and finally presents a design and simulation results of the proposed wireless sensor node using Proteus Design Suite for detecting frequency of sound exited by jetting gas, leaking from higher pressurised gas pipeline. This kind of proposed system can be useful to gas companies or industries whereby gas transportation is done
