    Design of a Proportional Integral Derivative Based Level Controller of a Blending Tank in Cement Plant
    (Bells University of Technology, 2020-06-03) AINA, Oluwatosin Adeola; Dr. A. O. Amole
    Rotary klin is the heart of the cement plant, and consistent feeding of material into it is key to achieving excellent performance in terms of equipment reliability and profitability. one of the significant ways to accomplish this is by using an appropriate PID Controller to control the level of the material in the klin feed blending tank. The use of PID controller has been severally applied tom the control of the level. However, the major challenges has to do with high overshoot and steady-state error, prolong settling time .and slow response of the controller, which practically will cause wastages and equipment downtime. Thus, this research focused on using PID controllers turned by Zigler-Nichols (ZN), Chien-Hrones-Reswick (CHR), and Cohen -Coon (CC) tuning technique to achieve optimum performance of the level control. The level of the blending tank was modeled based on the mass balance principle. The control schemes were simulated in MATLAB/SIMULINK version 9.7.01190202(R2013b), and the performance of each tuning technique was evaluated using the rise time, settling time, peak amplitude, and overshoot. The results revealed that ZN tuned PID controller resulted in the lowest rise time (2.11s), settling time of 14secs, and peak amplitude of 1.04 while both CHR and CC PID achieved the lowest overshoot of 0%.

    Development of a Matlab Based Pattern Design System for Plain Textile ( Ankara)
    (Bells University of technology, Ota, 2018-08-30) ELEGBEDE, Adedoyin Waheedat; Prof. O. L. Olopade
    Textile designing involves producing patterns for cloth used in clothing, household textile (such as towels) and decorative textile such as carpets. In the past, numerous printing techniques have been employed in patterning textiles an they an accurate representing of design when utilized but designs produced by the conventional method are static and rigid. Hence, MATLAB was used in this work to enable dynamic designs to be created for a particular textile material. This work developed patterns for printing different textiles and creative innovation designs using mathematics to server as instrument for artistic. The process begins with providing a plain textile material. A mathematical expression which generates the pattern is required. The pattern generated is assessed to check if it meets the intended design as well as the color the user requires. A different mathematical expression is used if the initially generated does not meet the requirement of the of the user. The final printing on the textile is done after the patterns have been arranged and the process simulated using MATLAB 8.5 simulation tool. This work presented eight different patterns namely: circular pattern - which is a combination of three concentric circles; floral 1,floral 2, combination floral, and petal pattern- which shows different kinds of floral design combined together as well as with other shapes; helical pattern which is a spring-like pattern; a star and a spiral pattern; designed using different mathematical expressions. These pattern can then be arranged different to form different designs on textile materials. A dynamic pattern design system for plain has been development in this work. This system can be effectively deployed in textile industries.

    Modelling and Simulstion of Internatuional Traveller's Check-In Process in Nigeria Airports using Apena Software and Simpy Simulation Tools
    (Bells University of Technology, 2020-08-06) OBETTA, James larry; Engr. Dr O. O. Olusanya
    Application of queuing theory to airport check-in problem is required to analyze the airport passenger flow process with respect to the service rendered to passengers during check-in process. This is necessary following the increasing demand for airport and airline services amidst limited facilities and dwindling number of trained personnel in most of the airports in the. This imbalance in demand and supply of facilities and services results in prolonged delays for all stakeholders (airports, airlines and passengers); which has the effect of impacting negatively negatively on ser vice performance, cost of operations, customers satisfaction, and overall throughput. Obviously, there is a cost attached to delay in any system irrespective of the cause of the delay. HENCE, this research is to model and simulation travelers' check -in process at the "D Wing of the Departure Hall of Murtala Muhammed International Airport, Ikeja, in year 2020. This research was carried out by determine the parameters of the queues at every services point in the check-in process, which were subjected to simulation runs, using Simpy simulation software, a framework based on standard Python. First, the check-in activities of the section were physically observed for five flights during which primary data were collected through direct observation.
