Industri pembuatan tekstil secara kecil-kecilan terkenal di pantai timur Semenanjung Malaysia. Ia dikenal oleh penduduk tempatan sebagai industri batik dan diwarisi turun-temurun. banyak menyumbang kepada pembangunan ekonomi negara kerana sambutan yang menggalakkan bukan sahaja dari pasaran malah luar negara. Di sebalik perkembangan ini, turut menghasilkan air sisa mengakibatkan pencemaran prosesnya menggunakan bahan kimia banyak. Kajian awal terhadap menunjukkan bahawa ia mengandungi gris,...

Abstract This paper presents the application of predictive control to drug dosing during anesthesia in patients undergoing surgery. A single‐input (propofol) single‐output (bispectral index (BIS)) model patient has been assumed for prediction. The performance our previous strategy improved tackle inter‐patient variability. set 12 models was studied and, order ensure applicability proposed controller, gain adaptation controller is proposed. Preliminary studies have shown that due static...

Maximizing the amount of monomeric sugar yield from lignocellulosic materials requires an effective pretreatment process and identification optimal enzyme loading for cost-effectiveness. In this work, a microwave-diluted sulfuric acid was applied prior to enzymatic hydrolysis sago palm bark (SPB). Characterization solid fraction completed before after process. Analysis SPB ash showed presence 6.8% silica. There 32% reduction in lignin content, increased crystallinity 29% 47%, clear damage...

Ordinary differential equations (ODEs) are widely used to describe the time evolution of natural phenomena across various scientific fields. Estimating parameters these systems from data is a challenging task, particularly when dealing with nonlinear and high-dimensional models. In this paper, we propose novel methodologies for parameter estimation in ODEs by using Newton-Raphson (NR) method Gradient Descent (GD) method. By leveraging discrete derivative Taylor expansion, problem formulated...

Cell migration, both in vivo and vitro, is a complex process governed by mechano-chemical interactions between cells the extracellular matrix (ECM). These interactions, mediated cell membrane receptors called integrins, involve bidirectional signaling intracellular actin cytoskeleton ECM. Integrins bind with cytoplasmic proteins to form adhesion complexes of varying sizes maturity, which play crucial roles cellular processes such as migration. Among these are nascent adhesions--the smallest...

Three types of microwave-assisted diluted solvents were employed using 0.1 N H2SO4 (MSA), NaOH (MSH), and 0.01 NaHCO3 (MSB). These evaluated as possible pretreatment routes for sago palm bark (SPB) with their effects on the pretreated substrate. A variety analyses, consisting fiber analysis, energy dispersive X-ray spectroscopy (EDX), fluorescence spectrometer (XRF), powder diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscope (SEM), high-performance liquid...

Closed-loop treatment for insulin dependent type 1 diabetes patients is a recent medical practice in delivery (bionic pancreas) which aims to achieve tight control of glucose level plasma and ensure minimizing risk hypoglicemia. Among those most popular closed-loop controller strategies, proportional integral derivative (PID) linear quadratic Gaussian (LQG) controllers are designed compared diabetic patients. The based on individual nominal model study the ability each order maintain blood...

Oil palm currently occupies the largest acreage of farm land in Malaysia. In 2011, production oil Malaysia was recorded as 19.8 million tons which has led to a huge amount wastewater known mill effluent (POME). This work focuses on ponding system acts treatment plant order treat POME. The conventional applied mills consists series seven ponds. maintenance costs pond are expensive thus study alternative methods is needed. POME using zeolite shows potential overcome problem. Samples collected...

Oil palm frond (OPF) fiber, a lignocellulosic waste from the oil industry, contains high cellulose and hemicellulose content, thus it is potential feedstock for simple sugars production. This paper describes two-stage hydrolysis process focusing on use of low-temperature dilute acid to convert in OPF fiber (xylose, arabinose, glucose). The objective present study was evaluate effect operating conditions sulfuric undertaken 1 L self-built batch reactor xylose production fiber. reaction were...
