    Development of a New Concept for Fire Fighting Robot Propulsion System
    (International Conference on Material, Industrial and Mechanical Engineering (ICMIME2016), 2006) Ajala, Mosud T.; Khan, M. R.; Shafie, Amir A.; Salami, Momoh-Jimoh E.
    An additional cost to human loss and property destruction during fire disaster is fire fighters injuries and death. The recent statistics of 63,350 fire fighters injuries that occurred during the year 2014 confirms that firefighting still presents great risks of personal injury to the fire fighters [1]. The lack of details on information about the victims trapped in fire and situation in the fire zone increase the risk to fire fighters [2, 3]. To reduce these fatalities fire fighting robots (FFRs) emerged as possible solutions therefore they are developed and researched on. The FFRs are designed for either prevention or emergency (same as intervention) tasks of fire and are applied indoor or outdoor. However, the prime movers of the majority of the FFRs are electrically powered [4] which made them to be suitable for preventive task alone and inappropriate for the emergency task. Their inappropriateness is due to the vulnerability in high temperature environment that characterised fire emergency. Thus, alternative propulsion systems for the mobility of fire fighting robots in emergency setting are evolving. Furthermore, literature survey reveals that water powered hydraulic propulsion system has been the only alternative to the drawbacks of dc motors in the hot environment. The mechanism was implemented on snake fire fighting robot for tunnel fire application [5]. In the mechanism, hydraulic motor was used to actuate the snake joints for mobility while water provides power for the hydraulic motors. However, the snake robot was designed for outdoor application. Consequently, the need for an autonomous fire fighting robot with a novel propulsion system becomes imminent.

    Development of mechatronics engineering degree program: challenges and prospects
    (Tempus Publications, 2003-01-01) Salami, Momoh-Jimoh E.; Mir-Nasiri, N.; Khan, M. R.
    It is now becoming common practice to include some courses in mechatronics in the traditional electrical and mechanical engineering programs. Whilst many engineering faculties have realized the need for a full-fledged multidisciplinary mechatronics engineering program, only in very few places have such programs been developed along the lines of other engineering programs. The justification for the mechatronics engineering program becomes evident, as today's engineers must be acquainted with subjects that are not taught or given much emphasis in the traditional engineering curriculum. A good knowledge in those subjects, is however required if our graduate engineers are to be relevant to industry with time. The challenges in developing such program in terms of curriculum planning, laboratory facility needs and staff requirements are discussed in this paper. Whilst there are immense advantages of such a discipline, its success depends on a balanced curriculum with good laboratory facilities and appropriate industrial links, positive attitudes and well-oriented academic staff as well as students having the ability to cope with diversified subjects.

    Performance evaluation of wet scrubber system for industrial air pollution control
    (ARPN Journal of Engineering and Applied Sciences, 2012-12) Danzomo, Bashir A.; Salami, Momoh-Jimoh E.; Jibrin, S.; Khan, M. R.; Nor, I. M.
    The concentration of pollutants emitted from industrial production are generally toxic and hazardous, which can be a serious health risk to humans not limited to respiratory ailments (asthma, bronchitis, tuberculosis, etc) but also to the photosynthesis in plants. In this study, a pilot scrubber system for PM10 control has been designed using data obtained from cement industry. A model for the overall collection efficiency of counter current scrubber system and Langmuir’s approximations were used to predict the performance of the system by considering droplet sizes of 500µm, 1000µm, 1500µm and 2000µm. The range of liquid to gas ratio recommended by the US Environmental Protection Agency (EPA) has been used to investigate the appropriate ratio for optimum performance of the system. Due to reversed flow in the Langmuir’s approximation, negative collection efficiencies for the 1µm dust particle were obtained. For 5µm and 10µm dust particles, the maximum collection efficiencies were determined to be 99.988% and 100.000% at 500µm droplet size and 2.7 l/m3 while the minimum was obtained to be 43.808% and 58.728% at 2000µm droplet size and 0.7 l/m3. The predicted performance of the scrubber system was then validated using the World Health Organization (WHO) air quality standard for PM10.
