\section{Introduction}

The first sentence should start here \cite{Kabir2023}. Should have \textcolor{red}{one spacing after section header}. The \textcolor{red}{indent of the first line of paragraph} should be \textcolor{red}{0.63cm. Content in body paragraph} should be written with the Font style: Calibri; \textcolor{red}{Font size: 12; Paragraph: Justify; Line spacing: 1.0.} For example: The last few decades have witnessed vast research on new types of heat transfer fluids, namely nanofluids. Nanofluid is a fluid that contains nanometer-sized solid particles. The nanofluid was introduced by Choi \textit{et al.,} [2] and it has been proven to give better heat transfer efficiency compared to conventional fluids.  Detailed reviews on the physical and thermal properties of nanofluids can be seen in review papers by several authors [3-5]. \textcolor{red}{Important note: Citation cannot stand alone as subject or object. It just as a supportive to a statement.} For example, “was also conducted by [4]", should be written as “was also conducted by \textcolor{red}{Uithof \textit{et al.,}} [4]” (\textit{et al., must be in italic style})\par

Second paragraph starts here (\textcolor{red}{no spacing between paragraphs}). For example: A nanofluid can be produced by dispersing metallic or non-metallic nanoparticles or nanofibers with a typical size of less than 100 nm in a base liquid.\par

Generally, in manuscript, should have: \textbf{1. Introduction} (research background and Literature Review);\textbf{ 2. Methodology; 3. Result; 4. Conclusion; Acknowledgment; References}. You may add more if required. The style of the section header as bellow:
\newline

\textbf{1. Introduction} (\textcolor{red}{\underbar{C}apital Letter of Each Word; No indent; Font style: Calibri \& Bold; Font Size: 12})
\textit{\\1.1 Sub Section Header (\textcolor{red}{\underbar{C}apital Letter of Each Word; No indent; Font style: Calibri \& Italic; Font Size: 12})
\\ 1.1.1 Sub sub section header (\textcolor{red}{\underbar{S}entence case; No indent; Font style: Calibri \& Italic; Font Size: 12})}\newline

Header level three (1.1.1) and above will follow header level three style. \textcolor{red}{No spacing between each header}. However, \textcolor{red}{before starting the first paragraph}, must have \textcolor{red}{one spacing after the header}.\par

In the \textcolor{red}{last paragraph of introduction section}, Authors should highlight the \textcolor{red}{gap} and \textcolor{red}{significant of the research} before write the \textcolor{red}{objective} of the research. These \textcolor{red}{three items} are very important and \textcolor{red}{compulsory}. ----End of Introduction Section----

\section{Methodology}

\subsection{Figure Style and Format}

For manuscript publication, all provided Figures must follow the standard of quality for publication. Authors \textcolor{red}{must provide} a \textcolor{red}{high quality} with \textcolor{red}{high resolution Figure}. \textcolor{red}{Content} in the Figure should be \textcolor{red}{clear} and \textcolor{red}{readable} as shown in Figure 1(b) (Especially, \textcolor{red}{the font size of contour legend}). For example, as in Figure 1

\begin{figure}[hbt!]
\centering
\includegraphics[width=1\textwidth]{Images/image3.png}
\hspace{-10pt} (a) (\textcolor{red}{Font style: Calibri; Font size: 10}) \hspace{50pt} (b)
\caption{\raggedright Figure quality (a) Unclear and unreadable content (b) Clear and readable content (\textcolor{red}{Font style: calibri; Font size: 11; Paragraph: Align left})}
\end{figure}

\textcolor{red}{Each Figure} must be \textcolor{red}{discussed} or \textcolor{red}{mentioned} in a body paragraph. The \textcolor{red}{Figure} must be \textcolor{red}{placed under} the \textcolor{red}{paragraph} that \textcolor{red}{discussed about the Figure}. Authors should \textcolor{red}{try} to make \textcolor{red}{economical use of the space} on the page; for example

\begin{enumerate}
\item [i.]	avoid excessively large white space borders around your graphics;
\vspace{-10pt}
\item [ii.]	try to design illustrations that make good use of the available space—avoid unnecessarily large amounts of white space within the graphic;
\item [iii.]	Use the suitable size of Figure. Not too big.
\vspace{-10pt}
\item [iv.]	Individual figures should normally be centered but place two figures side-by-side if they will fit comfortably like this as it saves space.
\end{enumerate}

Captions should be below the figure. The caption \textcolor{red}{SHOULD NOT} be finished with a full stop (period). The captions should be set to (a) the width of the figure for wider figures (b) centered across the width of the figure, as shown below

\begin{table}[hbt!]
  \centering
  \begin{tabular}{:p{7cm}:p{2cm}:p{6cm}:}
    \hdashline
    \multicolumn{3}{:c:}{\includegraphics[width=11.7cm, height=3cm]{Images/image4.png}}\\\hdashline
    \multicolumn{3}{:p{12.7cm}:}{\raggedleft\hspace{20pt}\textbf{Fig. 1.} In this case simply justify the caption so that is as the same width as the graphic}\\\hdashline
    \multicolumn{3}{:c:}{}\\\hdashline

    \textbf{Fig. 2.} These two figures have been placed side-by-side to save space&  &\textbf{Fig. 3.} These two figures have been placed side-by-side to save space\\
    \hdashline
  \end{tabular}
\end{table}
\vspace{-10pt}
\hspace{25pt}\colorbox{yellow}{Note: For long caption}

\begin{table}[hbt!]
    \centering
    \begin{tabular}{:c:}
      \hdashline
      \includegraphics[width=11.25cm, height=3.83cm]{Images/image7.png}\\\hdashline
      \textbf{Fig. 3.} Figure with short caption (caption centred)\\\hdashline

\textbf{For example:} A model of VFE-2 model was designed and fabricated in Universiti Malaysia wind tunnel under Malaysian Ministry of Education grant, as shown in \colorbox{yellow}{Figure 2} below [4]. The designed was exactly based on the original profile of Chu and Lucking [6] as \colorbox{yellow}{Figure 3}. \par

Few years later, a new research group is formed to further investigate the flow structure on the blunt-edged delta wing, the team called as Vortex Flow Experiment (VFE-2). The main objective of the VFE-2 test was to validate the results of Navier-Stokes calculations and to obtain a more detailed experimental data. The VFE-2 experiments were carried out for both sharp and blunt leading edge shape delta wing \cite{Strunk2000, Kabir2023, Kabir}. 

\begin{figure}[hbt!]

\adjustbox{minipage=\figurelength,center}{\caption{Comparison of experimental measurement and Numerical studies above VFE-2 configurations at $\alpha = 13^{\circ}$ \cite{Strunk2000}}}
\end{figure}

\begin{figure}[hbt!]
\centering
\includegraphics[height=7.5cm]{Images/image9.png}
\caption{UTM-LST delta wing VFE-2 profiles}
\end{figure}

Mat \textit{et al.,} [7] has performed a comprehensive flow visualization studies on blunt-edge delta wing. The primary vortex is developed at certain chordwise position and progress upstream with angle of attack; however, there is no data in VFE-2 indicating that the vortex progressed up to the Apex region with angle of attack increases.

\subsection{Table Style and Format}

\textcolor{red}{Table} should be placed at the \textcolor{red}{center}. \textcolor{red}{Each Table} must be \textcolor{red}{discussed} or \textcolor{red}{mentioned} in a body paragraph. The \textcolor{red}{Table} must be \textcolor{red}{placed under} the \textcolor{red}{paragraph} that \textcolor{red}{discussed about the Table. Font style} and \textcolor{red}{font size} of \textcolor{red}{content} in the Table are \textcolor{red}{Calibri} and \textcolor{red}{10}, respectively. The \textcolor{red}{content} must be \textcolor{red}{align left}. The \textcolor{red}{font size} of \textcolor{red}{Table caption} is \textcolor{red}{11}. The caption \textcolor{red}{SHOULD NOT} be finished with a full stop (period). The captions should be set to the width or within of the Table.

\begin{table}[hbt!]
    \addtolength{\tabcolsep}{+9pt}
    \caption{\hspace{60pt}Place the caption above the table. \newline Here the \textcolor{red}{caption} is \textcolor{red}{wider} than the table}
    \centering
    \begin{tabular}{rr}
    \toprule
         \textbf{Distance (m)} & \textbf{Velocity (m$\text{s}^{-1}$)}\\
         \midrule
         \textbf{A}& \textbf{1}\\ 
         \textbf{B}& \textbf{2}\\ 
         \textbf{C}& \textbf{3}\\ 
         \textbf{D}& \textbf{4}\\ 
         \bottomrule
    \end{tabular}
\end{table}

\begin{table}[hbt!]
    \addtolength{\tabcolsep}{+100pt} 
    \caption{\hspace{-50pt}Here the \textcolor{red}{caption} is \textcolor{red}{shorter} than the table}
    \centering
    \begin{tabular}{c}
    \toprule
         \textcolor{Blue}{\textbf{Reynolds}}\\
         \midrule
         \textbf{}\\  
         \bottomrule
    \end{tabular}
\end{table}

\subsection{Equation Style and Format}

All \textcolor{red}{equation} that mentioned in body paragraph should be written as \textcolor{red}{Eq. (1)}. Please use Microsoft Equation in order to present an equation. The \textcolor{red}{font size} of equation is \textcolor{red}{12}. Each equation must be numbered as follow

\begin{flalign}
& \text{Re} = \frac{\rho Vx}{\mu} &&
\end{flalign}

\section{Results}
\vspace{-10pt}
\subsection{Pressure Distribution}

\textbf{For example:} This section discusses the results obtained from the surface pressure measurement study. The effects of angle of attack, Reynolds number and leading edge bluntness are discussed in the next sub section. 

\subsubsection{The effect of angle of attack}
\vspace{-10pt}

The test configuration for this experiment is in \colorbox{yellow}{Table 1}. Nevertheless for the experiment at Reynolds number of $2\times 10^6$, the angle of attack was limited to $\alpha = 23^{\circ}$ only.

\vspace{10pt}\hspace{200pt}\colorbox{yellow}{\textbf{Table 1}}
\vspace{-10pt}
\begin{table}[hbt!]
    \addtolength{\tabcolsep}{+100pt} 
    \caption*{\hspace{-40pt}The values of Reynolds number and velocity}
    \centering
    \begin{tabular}{c}
    \toprule
         \textcolor{Blue}{\textbf{Reynolds}}\\
         \midrule
         \textbf{}\\ 
         \bottomrule
    \end{tabular}
\end{table}

To differentiate the effects of Reynolds number, the experiments was also performed at two speeds of 18 m/s and 36 m/s that corresponding to $1\times 10^6$ and $2\times 10^6$ Reynolds number, calculated from \colorbox{yellow}{Eq. (1)} and summarize in Table 1.  

\begin{flalign}
    & \text{Re} = \frac{\rho Vx}{\mu} && \tag{1}
\end{flalign}

where the dynamic viscosity, $\mu$, density of air, $\rho$ and length, $x$ were taken as $1.846\times 10^{-5} \text{ kg/ms} 10^{-5}$, $1.18 \text{ kg/m}^3$ and 0.874 m respectively.

\section{Conclusions}

In \textcolor{red}{conclusion part}, \textcolor{red}{Author} should \textcolor{red}{highlight} the \textcolor{red}{finding} of their research that \textcolor{red}{respond} to the research \textcolor{red}{objective}. \textbf{For example:} The experimental data of UTM-LST VFE-2 model at high angle of attack is presented here. More experiments are needed to verify this complicated flow topology.
