Chapter 1. Nonlinear Equation

by farhanajohar | Sep 6, 2016 | Subject: Numerical Methods

In physical sciences, a nonlinear system is a system in which the output is not directly proportional to the input. Nonlinear problems are of interest to engineers, physicists and mathematicians and many other scientists because most systems are inherently nonlinear in nature. Nonlinear systems may appear chaotic, unpredictable or counterintuitive, contrasting with the much simpler linear systems.

Typically, the behavior of a nonlinear system is described in mathematics by a nonlinear system of equations, which is a set of simultaneous equations in which the unknowns (or the unknown functions in the case of differential equations) appear as variables of a polynomial of degree higher than one or in the argument of a function which is not a polynomial of degree one. In other words, in a nonlinear system of equations, the equation(s) to be solved cannot be written as a linear combination of the unknown variables or functions that appear in them. It does not matter if nonlinear known functions appear in the equations. In particular, a differential equation is linear if it is linear in terms of the unknown function and its derivatives, even if nonlinear in terms of the other variables appearing in it.

Numerical Methods: Introduction

by farhanajohar | Sep 6, 2016 | Subject: Numerical Methods

Analytical methods are typically only solvable in cases of “simple” models. Numerical methods, in contrast, provide ways to manipulate complex math problems so that they may be solved by simple processes. These methods allow for imperfect and complex models to be approximated, usually with great accuracy. Numerical methods can account for more variables and dimensions than would be solvable when using analytical methods.

Note that the numerical solution is an approximation. In most cases it will be close enough, which is fine for most engineering problems. Typically mathematicians have more time and funding to find an analytical solution, but the demands of business usually necessitates an approximate solution for engineers working in industry.

Beban kerja dan KPI

by farhanajohar | Aug 16, 2016 | Work Is Ibadat 🙂

Lama tidak menulis. Pelbagai taskforce dan program berlangsung. Namun, tidak berkesempatan untuk melaporkan.

Seakan telah mula men’daki’ ke arah pencapaian yang sepatutnya walaupun masih merangkak dan belajar. Tugas pensyarah dahulu dan sekarang amat jauh berbeza. Pelbagai target yang perlu dicapai. Bermula dengan target universiti, kemudian di bawa ke peringkat fakulti dan seterusnya jabatan. Mendapat title Research University juga menuntut pelbagai ‘sokongan’ semua staf. Perlu memenuhi syarat itu dan ini. Alhamdulillah kerja keras semua dari peringkat jabatan dan fakulti di UTM telah memartabatkan UTM sebagai one of Research University.

Kisah tidak berakhir di situ. Untuk mengekalkan title ini lagi memerlukan usaha yang maha berlipat ganda. Maka segala KPI dibentuk bg memastikan misi ini berjaya. Itulah beban yang sama-sama perlu kita pikul untuk mengekalkan taraf UTM pada level ini malah mencapai lebih tinggi lagi.

Dari merangkak, cuba berlari..dah cuba memecut. Tapi ‘pancit’ juga ditengah jalan. 🙂

Akhirnya balik kepada kemampuan. Melaksanakan segala tanggungjawab dengan baik dan penuh dedikasi setakat yg mampu. Kesihatan perlu dijaga. -alasan hehe

Apapun, tidak lah sampai kita berhenti. Terus, dan teruskan segala misi ‘Demi Tuhan untuk Manusia’-UTM

Never Give Up!

by farhanajohar | Mar 31, 2016 | Personal

(Full Malay Version)

Apapun yang kita buat, never give up!

Walaupun hampir gagal dan tersungkur, cari semula kekuatan diri dan teruskan melangkah. Pelbagai ujian dan dugaan dilalui dalam mencari ilmu tetapi kita harus terus melangkah. Dengan status sebagai pelajar, isteri dan ibu semestinya 24 jam yang ada adalah sangat mencabar.

Pelbagai dilemma, bertarung dengan perasaan sendiri, namun niat untuk mengalah padam segera. Apa yang telah kita mulakan, perlu kita habiskan. Apapun, ingat, rezeki itu dari Allah. Sentiasa berdoa dan berusaha namun kita tahu Allah penentu segala.

Mungkin bukan hari ini, esok atau lusa, tapi sentiasa lah berdoa kerana Allah tahu bila waktu kita perlu. Semoga kejayaan juga milik mereka yang sentiasa berusaha dan bertawakal. Ameenn.

Bengkel yang berbaloi dihadiri. Mengajar kita how to use elearning semaksimum mungkin.

Meeting of Task Force Analisis Pengoptimumam Staf Kontrak Fakulti Sains

by farhanajohar | Feb 16, 2016 | Work Is Ibadat 🙂

Venue: Makmal Komputer 3, 2.30-5.00pm

Basically, perlukan some indicator siapa yang perlu dan siapa yang tidak based on the allocation budget yang diberi.

Aim: to come out with one model which can be used to determine which staff is perform well and manage to help faculty and university in terms of teaching, research and dana as well.
