Finite Element Formulations for Statics and Dynamics of Plane Structures (with Matlab)

This book was written by my Husband and Few MSNM Fellow.

This book has evolved from a series of lecture notes of the first author refined over the period of ten years with the co-authors. It revolves around frame structural analysis, both statics and dynamics. In Chapter 1, the book begins with the basic concepts of numerical methods before introducing the concept of Galerkin weighted residual method towards the end. Chapter 2 focuses on bar finite element. The formulation of beam element is discussed in Chapter 3. Chapter 4 discusses the concept of space orientation and the assembly of elements for plane structures (truss and frame). Chapter 5 discusses two classes of eigenvalue problems; free vibration and buckling of structures. Chapter 6 details the formulation of forced vibration of bar, beam and plane frame. In this final chapter, time discretization by finite difference method is introduced.

Meshless point interpolation formulation of kinematic wave equation for flood routing

This study presents the meshless Point Interpolation Method (PIM) formulation to solve the kinematic wave equation for flood routing. It details on Galerkin residual method employing PIM shape functions in discretizing the unsteady partial differential equation. Two nonlinear solvers are considered; Picard and Newton-Raphson. The formulation is verified against both hypothetical data obtained from conventional numerical methods (finite difference and finite element method) and gauged data obtained from an actual river. Close agreements are obtained between the proposed PIM formulation and the conventional methods, thus highlight the potential of PIM as an alternative numerical method in the field of hydrologic modeling.

Performance of vapour pressure models in the computation of vapour pressure and evapotranspiration in Abha, Asir region, Saudi Arabia

The main aim of this research work is to assess the performance of the various mass transfer-based method with respect to standard FAO56-PM. Daily meteorological data from 1979 to 2018 has been used to compute reference evapotranspiration (ETo). The climatic data from 1979 to 2006 were used for the development of the calibrated equations and data from 2007 to 2018 were applied for validation purpose. The evaluated, calibrated and further validation of calibrated models were compared using statistical tools in order to ranked the models effectiveness using Global Performance Indicator (GPI) where higher GPI value shows better model. The models were then arranged using GPI and it was found that proposed model resulted with best GPI value of 5.02, 2.85 and 5.19 during evaluation, calibration and validation respectively followed by Albrecht model. The results of this study could be used by the water management system, crop cultivators, crop advisors, researchers from research centres. Moreover, it is beneficial for the decision maker in the vast field of agriculture, hydrology and environment. The calibration and validation of different ETo equations tend to increase their performance. Thus, the validated evapotranspiration model that used less climatic parameters can predict the ETo condition accurately for Asir region.

Pindah ke Malaysia-Japan International Institute Technology (MJIIT) UTM KL

Assalamulaikum,

Selepas 18 Tahun di UTM Johor sebagai pensyarah di Sekolah Kejuruteraan Awam (2001 – 2019) dan 4 Tahun sebagai pelajar Undergraduate (199-1999) akhirnya saya tinggalkan UTM Skudai Johor. Saya dapat berpindah ke UTM KL di bawah fakulti Malaysia-Japan International Institute Technology.
Seronok sebab akhirnya dapat kembali bersama dengan keluarga selepas 5 tahun berulang-alik dari ipoh ke JB kemudian dari KL-JB setiap minggu.
Sedih sebab dah lama sangat di UTM Johor dan banyak sangat yang telah dilalui.

Anyway, sebab kan ini, saya teringat yang my husband, Dr. Airil (AirilSametok) ada buatkan satu lagu perpisahan dengan UTM ni, dan saya nak sharekan di sini.
