Utilizing Analytical Hierarchy Process for Pauper House Programme in Malaysia
In Malaysia, the selection and evaluation of candidates for
Pauper House Programme (PHP) are done manually. In
this paper, a technique based on Analytical Hierarchy
Technique (AHP) is designed and developed in order to
make an evaluation and selection of PHP application. The
aim is to ensure the selection process is more precise,
accurate and can avoid any biasness issue. This technique
is studied and designed based on the Pauper assessment
technique from one of district offices in Malaysia. A
hierarchical indexes are designed based on the criteria that
been used in the official form of PHP application. A
number of 23 samples of data which had been endorsed
by Exco of State in Malaysia are used to test this
technique. Furthermore the comparison of those two
methods are given in this paper. All the calculations of
this technique are done in a software namely Expert
Choice version 11.5. By comparing the manual and AHP
shows that there are three (3) samples that are not
qualified. The developed technique also satisfies in term
of ease of accuracy and preciseness but need a further
study due to some limitation as explained in the
recommendation of this paper
Hybrid Palm Oil Mills Maintenance System
This paper proposes a technique that enhances snapshot model for cause of failure and decision analysis in order to easily assist maintenance engineers during identification and definition of the actual maintenance problem. The technique is a hybrid of failure mode, effect and criticality analysis, information technology and decision analysis into the snapshot model. A tool that automates the hybrid of snapshot modelling for cause of failure and decision analysis is also developed. This tool aims to ensure maintenance engineers can conduct snapshot modelling with little or without the help of operation research experts to facilitate in the cause of failure and decision analysis process
Application of ANFIS in predicting TiAlN coatings flank wear
In this paper, a new approach in predicting the
flank wear of Titanium Aluminum Nitrite (TiAlN) coatings
using Adaptive Network Based Fuzzy Inference System
(ANFIS) is implemented. TiAlN coated cutting tool is widely
used in machining due to its excellent resistance to wear. The
TiAlN coatings were formed using Physical Vapor Deposition
(PVD) magnetron sputtering process. The substrate sputtering
power, bias voltage and temperature were selected as the input
parameters and the flank wear as an output of the process. A
statistical design of experiment called Response Surface
Methodology (RSM) was used in collecting optimized data. The
ANFIS model was trained using the limited experimental data.
The triangular, trapezoidal, bell and Gaussian shapes of
membership functions were used for inputs as well as output.
The results of ANFIS model were validated with the testing
data and compared with fuzzy rule-based and RSM flank wear
models in terms of the root mean square error (RMSE), coefficient
determination (R2) and model accuracy (A). The result
indicated that the ANFIS model using three bell shapes
membership function obtained better result compared to the
fuzzy and RSM flank wear models. The result also indicated
that the ANFIS model could predict the output response in
high prediction accuracy even using limited training data
Application of ANFIS in Predicting of TiAlN Coatings Hardness
In this paper, a new approach in predicting the hardness of Titanium Aluminum Nitrite
(TiAlN) coatings using Adaptive Neuro-Fuzzy Inference System (ANFIS) is implemented. TiAlN
coated cutting tool is widely used in machining due to its excellent properties. The TiAlN coatings
were formed using Physical Vapor Deposition (PVD) magnetron sputtering process. The substrate
sputtering power, bias voltage and temperature were selected as the input parameters and the hardness
as an output of the process. A statistical design of experiment called Response Surface Methodology
(RSM) was used in collecting optimized data. The ANFIS model was trained using the limited
experimental data. The triangular, trapezoidal, bell and Gaussian shapes of membership functions
were used for inputs as well as output. The results of ANFIS model were validated with the testing
data and compared with fuzzy and nonlinear RSM hardness models in terms of the root mean square
error (RMSE) and model prediction accuracy. The result indicated that the ANFIS model using 3-3-3
triangular shapes membership function obtained better result compared to the fuzzy and nonlinear
RSM hardness models. The result also indicated that the ANFIS model could predict the output
response in high prediction accuracy even using limited training data
Online performance dialogue system model (e-DP): a requirement analysis study at Batu Pahat district education office
This study aims to identify the viewpoint of school leaders the need of developing Online Performance Dialogue (EDP). The model based on the method of inquiry for educational leaders and the School District. The theory is used as a model UTAUT basis for this study. Survey methods used between 222 schools investigate the needs of leaders to adopt Online Performance Dialog (eDP) The data obtained were analyzed through descriptive Statistics using statistical package for social science (SPSS) software. Interpretation of the data is based on the value of the mean and standard deviation. Overall findings indicate that school leaders need on-line performance dialogue (eDP) with an average mean 4.309. The findings of this study reveal that school leaders have access to the necessary technology to eDP. The results also showed the level of acceptance and the intention to use the eDP model among school leaders
UPPER LIMB JOINTS AND MOTIONS SAMPLING SYSTEM USING KINECT CAMERA
The needs of research on human posture and its joint-motion relationships are important. Providing a real-time postural measurement tool has attracted the attention of many human postural-related researchers. This study has developed and performed a validation analysis on a new innovative system for sampling and finding the angles of motions of each posture with its related joints using Kinect camera. The validation investigated the static and dynamic accuracy analyses by comparing to a Jamar goniometer and ErgoFellow system. The results showed that Mean Absolute Errors of Kinect in static and dynamic motions are 15.12% and 45.33% respectively. It is concluded that the postural measurement system developed by this study requires further improvements
Migration control: A distance compensation strategy in ants
©The Author(s) 2016. This article is published with open access at Springerlink.com. Migratory behaviour forms an intrinsic part of the life histories of many organisms but is often a high-risk process. Consequently, varied strategies have evolved to negate such risks, but empirical data relating to their functioning are limited. In this study, we use the model system of the househunting ant Temnothorax albipennis to demonstrate a key strategy that can shorten migration exposure times in a group of social insects. Colonies of these ants frequently migrate to new nest sites, and due to the nature of their habitat, the distances over which they do so are variable, leading to fluctuating potential costs dependent on migration parameters. We show that colonies of this species facultatively alter the dynamics of a migration and so compensate for the distance over which a given migration occurs. Specifically, they achieve this by modulating the rate of ‘tandem running’, in which workers teach each other the route to a new nest site. Using this method, colonies are able to engage a larger number of individuals in the migration process when the distance to be traversed is greater, and furthermore, the system appears to be based on perceived encounter rate at the individual level. This form of decentralised control highlights the adaptive nature of a behaviour of ecological importance, and indicates that the key to its robustness lies in the use of simple rules. Additionally, our results suggest that such coordinated group reactions are central to achieving the high levels of ecological success seen in many eusocial organisms
