Modelling For Temperature Non-Isothermal Continuous Stirred Tank Reactor Using Fuzzy Logic

As we study chemical engineering and in process engineering, we come across the importance of a Continuous Stirred Tank Reactor, CSTR. Many types of controllers have been applied on the CSTR process to control the reactor temperature. In this research paper, an analysis of the response of the conventional Proportional-Integral-Derivative, PID controller and multi types of Fuzzy Logic controller for temperature control of CSTR and to design a control system of a non-isothermal temperature control of a CSTR in order to produce the most theoretically stable response curve. A mathematical model of a CSTR using the most general operating condition was developed through a set of differential equations which were later then converted into S-function using MATLAB (Matrix Laboratory) editor. After developing the S-function of the defined CSTR model was used in SIMULINK (a graphical programming environment from MATLAB), model by using a path called User-Defined functions which allows us to apply a M.file system that was created prior to the simulation as for this project we used a system block of the S-function or S-function builder

Modelling for Temperature Non-Isothermal Continuous Stirred Tank Reactor Using Fuzzy Logic

Many types of controllers were applied on the continuous stirred tank reactor (CSTR) unit to control the temperature. In this research paper, Proportional-Integral-Derivative (PID) controller are compared with Fuzzy Logic controller for temperature control of CSTR. The control system for temperature non-isothermal of a CSTR will produce a stable response curve to its set point temperature. A mathematical model of a CSTR using the most general operating condition was developed through a set of differential equations into S-function using MATLAB. The reactor model and S-function are developed using m.file. After developing the S-function of CSTR model, User-Defined functions are used to link to SIMULINK file. Results that are obtained from simulation and temperature control were better when using Fuzzy logic control compared to PID control

Relationships between organizational commitment, job satisfaction and stress with intention to leave among employees of Appfuxion Consulting Sdn Bhd

This research aims to examine the relationships between organizational commitment, job stress and job satisfaction with the intention to leave among the employees of AppFuxion Consulting Sdn Bhd. The study was conducted using the descriptive research method to ensure that the data collected meet the research objectives. Some 92 samples were collected from the employees of AppFuxion Consulting Sdn Bhd with about a total of about 120 population. The quantitative analysis, Cronbach Alpha test and Pearson Correlation test were performed using the Statistical Package for Social Science (SPSS) Version 23.0. This research also involved a cross-sectional review of the previous researches on the factors that influenced the intention to leave among employees in other sectors. Job stress are significant positive relationship between intention to leave and job stress with (β = 0.837) and (p = 0.000). Job satisfaction are significant negative relationship between intention to leave and job satisfaction with (β = - 0.008) and (p = 0.942). Organizational Commitment are significant positive relationship between intention to leave and organizational commitment with (β = 0.012) and (p = 0.925). It shown that all three independent variable have influence toward intention to leave

The Comparison of Bearing Capacity Calculation Obtained based on SPT-N from Seismic Survey against Strength Parameters (c’ and φ) value from Soil Drilling

Soil investigation is a method of obtaining data for a particular area regarding the properties of subsoil which includes fieldworks and laboratory tests. Nowadays, conventional techniques are mostly used for soil investigation but there are a few disadvantages of using it have been discovered. The disadvantages of using conventional techniques are costly, time consuming, destructive and limited of equipment mobilization. The scope of study for this research is to determine the bearing capacity calculation obtained based on two different methods which are SPT- N from seismic survey and strength parameters (c’ and φ) from soil drilling

COMPARATIVE STUDY ON HONEYCOMB STRUCTURE FOR WEIGHT REDUCTION OF GANGWAY MONORAIL

Lightweight materials nowadays usually applied in transportation industry. The transportation industry is continuously searching for methods to increase efficiency and decrease fuel consumption. Weight reduction in gangway monorail is a systematic approach that needs to be thoroughly planned, implemented, and maintained in order to coordinate efficient and cost effective. The monorail industry takes into account regarding weight ratio seriously plus added with the weight of passengers. This is where weight reduction plays an important role to increase the efficiency and ensure the integrity of monorail industry. This project is aimed to study the comparison of weight reduction of gangway monorail by comparing existing and new result using NX Nastran but maintains the performance specifications as the weight of gangway is too heavy and must be reduced from 615kg to 510kg. Only part of gangway which is main frame will be analyzed since this is the most critical area where passengers standing. Furthermore, the criteria of Kuala Lumpur Monorail Fleet Expansion (KLMFEP) will be evaluated into this project and aluminium honeycomb sandwich panel is to replace as the new material. In addition, the first stage of the project is by designing the gangway main frame following the original shape and continued by analysis by NX Nastran to see the difference results. The final outcome of this project is a demonstration of aluminium honeycomb sandwich panel in gangway monorail with safety factor and its behavior that is illustrated by a simple practicality of graphical visual engineering interface. In which, the manufacturer can utilized this study as improvement in monorail industry and monitor the performance of the material to make important economic and safety decision. It is hoped that this project will benefit engineers and manufacturers that is currently working on reducing weight of gangway monorail
