Fuzzy Topological Topographic Mapping (F T T M ) is a model for solving neuromagnetic inverse problem. F T T M consists of four components and connected by three algorithms. F T T M version 1 and F T T M version 2 were designed to present 3D view of an unbounded single current and bounded multicurrent sources, respectively. In 2008, Suhana proved the conjecture posed by Liau in 2005 such that if there exist n number of F T T M , then n 4 − n new elements of F T T M will be generated from it. In this paper, a new proof of sequence of F T T M is presented using k-Fibonacci sequence.

Dalam konteks penyebaran COVID-19, permodelan matematik telah menjadi satu komponen penting dalam merangka strategi bagi mengambil langkah awal dalam menangani penularan wabak. Dalam kajian ini, model SIR (“Susceptible” – “Infected” – “Removed”) digunakan bagi meramalkan tindak balas wabak COVID-19 di Malaysia. Menggunakan data rasmi daripada Kementerian Kesihatan Malaysia, didapati kes puncak Ketika PKP 1.0 berlaku pada t=21 hari (8 April 2020) dengan kadar jangkitan a = 0.19. Hasil kajian mendapati bahawa wujud perbezaan yang ketara sekiranya bilangan penduduk yang berpotensi dijangkiti S(0) dikurangkan, di mana puncak kes aktif dapat dikurangkan dengan begitu ketara (kes aktif puncak berlaku pada t=81, dengan peratusan kes berjumlah S(81) = 8.7%). Jadi, adalah amat penting bagi mematuhi arahan – arahan serta SOP yang digariskan oleh pihak kerajaan bagi menghentikan jangkitan pandemik COVID-19.

The spread of novel coronavirus disease (COVID-19) has resulted in chaos around the globe. The infected cases are still increasing, with many countries still showing a trend of growing daily cases. To forecast the trend of active cases, a mathematical model, namely the SIR model was used, to visualize the spread of COVID-19. For this article, the forecast of the spread of the virus in Malaysia has been made, assuming that all Malaysian will eventually be susceptible. With no vaccine and antiviral drug currently developed, the visualization of how the peak of infection (namely flattening the curve) can be reduced to minimize the effect of COVID-19 disease. For Malaysians, let's ensure to follow the rules and obey the SOP to lower the R 0 value from time to time, hoping that the virus will vanish one day.
