The study of splicing systems and their language has grown rapidly since Paun developed a splicing system known as a regular splicing scheme that produces a regular language. Since then, the researchers have been eager to classify the splicing language into certain classes in the Chomsky hierarchy, such as context-free language, context-sensitive language and recursive enumerable language. Previously, the study on the n-th order limit language was conducted from the biological perspective to the limit language produced. Still, no research has been done from the generation of language point of view. This research presents a generalization on the type of classes of the formal language, the n-th order limit language. The cases to obtain the n-th order limit language are revisited and used to obtain the types of language classes according to the Chomsky hierarchy produced by the n-th order limit language.
自从保恩提出了一种能产生规则语言的拼接系统(称为规则拼接方案)以来,对拼接系统及其语言的研究迅速发展。此后,研究人员一直渴望将拼接语言划分为乔姆斯基等级体系中的某些类别,如无语境语言、语境敏感语言和递归可数语言。在此之前,关于 n 阶极限语言的研究都是从生物学角度对产生的极限语言进行的。但是,还没有人从语言生成的角度进行过研究。本研究提出了对形式语言--n-阶极限语言--类别类型的概括。本研究重新审视了获得 n 阶极限语言的案例,并根据 n 阶极限语言产生的乔姆斯基层次结构来获得语言类别的类型。

The optical response of the photonic crystal structure has been analyzed using the Finite Difference Frequency Domain (FDFD) method. Simulation using this method aims to analyze the characteristics of light transmission when interacting with related structure. The results of the study of photonic crystal structures with two defects show that there are two transmittance bands called double resonances at two specific wavelengths. Changes in the resonance peak with respect to the variations of refractive index in the second defect layer resulted in a linear change with significant sensitivity. For photonic crystals with two defects, the first defect is a metal layer and the second defect is material sensing, which produces double resonance with a sensitivity of 7,825 and 3,2675, while for photonic crystals with the first defect, a dielectric layer, and the second defect is material sensing, produces single resonance with a sensitivity of 2,022. The choice of the first defect is that the metal layer is quite important, in addition to producing greater sensitivity, it also produces a field enhancement between the dielectric and the metal layer which is called surface plasmon resonance (SPR). The sensitivity value can also be set by determining the thickness of the second defect layer. These results can be used as a standard for fabrication and developed for sensor applications.
利用有限差分频域(FDFD)方法分析了光子晶体结构的光学响应。使用这种方法进行模拟的目的是分析光与相关结构相互作用时的传输特性。对带有两个缺陷的光子晶体结构的研究结果表明,在两个特定波长处存在两个称为双共振的透射带。共振峰的变化与第二个缺陷层的折射率变化有关,导致线性变化,具有显著的灵敏度。对于有两个缺陷的光子晶体,第一个缺陷是金属层,第二个缺陷是材料感应层,产生的双共振灵敏度分别为 7825 和 32675;而对于第一个缺陷是介电层,第二个缺陷是材料感应层的光子晶体,产生的单共振灵敏度为 2022。之所以选择第一个缺陷,是因为金属层相当重要,它除了能产生更高的灵敏度外,还能在介电层和金属层之间产生场增强,这就是所谓的表面等离子体共振(SPR)。灵敏度值也可以通过确定第二个缺陷层的厚度来设定。这些结果可作为制造和开发传感器应用的标准。

Craniosynostosis syndrome is a congenital condition occurring due to the abnormal development of the skull, leading to abnormalities in skull morphology. Apert syndrome is one of common craniosynostosis syndrome in Malaysia and this syndrome can be categorized as the severe craniofacial disorders. The abnormalities of skull morphological in Apert syndrome patient can be identified as outliers which are investigated in this study. This study presents a skull morphological analysis based on a case study involving six paediatric patients diagnosed with Apert syndrome, alongside 22 control patients aged 0 to 12 years, all of whom underwent treatment at the University Malaya Medical Centre (UMMC). The computerized tomography scan (CTSCAN) data is provided by UMMC recorded from year 2012 until 2020 and the data is measured using MIMICS software by taking the measurement of cranial angles. The clustering-based procedures will be applied to identify the abnormalities in skull angle dataset. There are 12 skull angles and these angles are analysed using hierarchical clustering algorithms for identifying the outliers or abnormalities. The objective is to detect the abnormalities and determine the skull angles that associated with Apert syndrome (AS) in Malaysia population using clustering-based procedure. The abnormalities in Apert syndrome datasets are successfully detected by the algorithms and this study found that there are skull angles with specific location of angles are associated with Apert syndrome. This study also found that the location of skull angles for patients age 0-24 months old and >24 months old are different. The findings of this study can assist the surgical team in directing additional focus towards specific regions of the skull during the planning of interventions. This guidance has the potential to optimize surgical outcomes and reduce the risk of potential complications.
颅骨发育异常综合症是一种先天性疾病,由于头骨发育异常,导致头骨形态异常。阿博特综合征是马来西亚常见的颅骨发育异常综合征之一,该综合征可归类为严重的颅面疾病。阿博特综合征患者的头骨形态异常可被识别为异常值,本研究对其进行了调查。本研究基于一项病例研究,对六名被诊断为阿博特综合征的儿童患者以及 22 名年龄在 0 至 12 岁之间的对照组患者进行了头骨形态分析,所有患者均在马来亚大学医疗中心(UMMC)接受了治疗。计算机断层扫描(CTSCAN)数据由马来亚大学医疗中心提供,记录时间为 2012 年至 2020 年,数据使用 MIMICS 软件测量头颅角度。基于聚类的程序将用于识别头颅角度数据集中的异常。头骨角度共有 12 个,使用分层聚类算法对这些角度进行分析,以识别异常值或异常情况。目的是使用基于聚类的程序检测异常情况,并确定马来西亚人群中与阿博特综合征(AS)相关的头骨角度。该算法成功地检测出了阿博特综合征数据集中的异常情况,研究发现,有些头骨角度的特定位置与阿博特综合征有关。这项研究还发现,0-24 个月和大于 24 个月的患者头骨角度的位置是不同的。这项研究的结果可以帮助手术团队在制定干预计划时,将更多的注意力集中在头骨的特定区域。这种指导有可能优化手术效果并降低潜在并发症的风险。

The algorithms for processing images and videos are currently essential for many applications. Many of these applications are specified for processing and analyzing images of numbers, such as smart meter reading, automated document processing, and processing of vehicles and license plate images in traffic monitoring and analysis. Consequently, eliminating noise is frequently used as a pre-processing step to improve subsequent analysis and processing outcomes. In this context, this manuscript proposes using artificial intelligence-based methods to increase the efficiency of the image-denoising process. However, the computational demands of these algorithms necessitate careful consideration of the hardware on which they are implemented. Therefore, this paper proposes using the simple autoencoder approach and evaluates its efficiency compared to the conventional methods. This unsupervised model is trained to identify and remove impulse noise from digital images by replacing some pixels with others from the outer dataset that can clarify the whole image more. The model was trained using handwritten numbers, MNIST, and data set size in the first trial and the FER2013 dataset in the second. The model is superior in the case of the simple dataset. Two versions of autoencoders are considered, the first with three layers and the second with five. The Traditional denoising methods are investigated for comparison purposes. The four conventional filtering procedures, AMF, DBMF, ADBMF, and MDBUTMF, are implemented using the MATLAB simulation environment, and the results are reported and compared with the proposed methodology. The results show that the proposed artificial intelligence-based method significantly outperforms the traditional methods regarding processing efficiency and the resulting image quality. Moreover, the computational intensity for the proposed methodology is chosen as a metric for evaluating the algorithm compliance for the hardware implementation compared to the other Artificial Intelligence (AI)-based denoising algorithms. The suggested technique has minor processing and training time compared to the other AI-based methods with adequate quality in case the images of numbers usually do not contain many details, making it more convenient for hardware implementation.
目前,处理图像和视频的算法对许多应用都至关重要。其中许多应用都指定要对数字图像进行处理和分析,例如智能抄表、自动文档处理以及交通监控和分析中的车辆和车牌图像处理。因此,消除噪声经常被用作预处理步骤,以改善后续分析和处理结果。在这种情况下,本手稿建议使用基于人工智能的方法来提高图像去噪过程的效率。然而,由于这些算法对计算量的要求较高,因此必须仔细考虑实现这些算法的硬件。因此,本文建议使用简单的自动编码器方法,并评估其与传统方法相比的效率。通过用外部数据集中的其他像素替换部分像素,可以使整个图像更加清晰,从而训练出这种无监督模型,用于识别和去除数字图像中的脉冲噪声。第一次试验使用手写数字、MNIST 和数据集大小来训练模型,第二次试验使用 FER2013 数据集来训练模型。在简单数据集的情况下,该模型更胜一筹。我们考虑了两种版本的自动编码器,第一种有三层,第二种有五层。为了进行比较,对传统的去噪方法进行了研究。使用 MATLAB 仿真环境实现了四种传统滤波程序:AMF、DBMF、ADBMF 和 MDBUTMF,并报告了结果,并与所提出的方法进行了比较。结果表明,所提出的基于人工智能的方法在处理效率和图像质量方面明显优于传统方法。此外,与其他基于人工智能(AI)的去噪算法相比,建议方法的计算强度被选为评估硬件实现算法合规性的指标。在数字图像通常不包含很多细节的情况下,建议的技术与其他基于人工智能的方法相比,处理和训练时间较短,但质量足够高,因此更便于硬件实施。

The Vehicle Routing Problem (VRP) involves a set of customers with known locations, each having a certain demand for goods or services. There is also a fleet of vehicles available, each with limited capacity and often a fixed starting point. With the aid of mathematical programming tools, this paper offers an overview of the most recent VRP research. This study also examines the algorithms for solving VRP models and categorizes them in terms of their application areas. For these reasons, related publications that appeared in the international journal have been compiled and studied. According to the literature review, multi-criteria decision-making (MCDM) techniques have yet to constitute the most mathematical programming methods used to solve the VRP problem.

The Gemas – Johor Bahru Electrified Double Track Project (GJBEDTP) is the most recent railway electrification. GJBEDTP runs from Gemas Railway Station to Johore Bahru (JB) Sentral. Since the JB Sentral station platform track is existing, it cannot achieve the minimal offset in the client's Statement of Needs (SON). The station canopy's acting load capacity is limited, so it cannot support the Overhead Line Equipment (OLE). Malaysia's standard offset value was 3.0 m, while the KTMB guideline's maximum offset value is 3.60 m and the minimum is 2.60 m. Thus, this research investigates the concrete mast offset that should be used when track separation is lower than standard. JB Sentral architecture data was collected to evaluate the mast offset. Sicat Master simulation and a cross-sectional diagram can be used to determine the proper minimum offset from the data collected. The results show that the mast at the centre of the two tracks can achieve clearances with the minimum offset of 1.80 m from the track centreline to the concrete mast face. These results also show that tangent track alignment allows a minimum offset of 1.80 m at a lower train speed.
吉马士 - 新山电气化双轨项目(GJBEDTP)是最新的铁路电气化项目。GJBEDTP 从 Gemas 火车站到新山(JB)中央火车站。由于 JB Sentral 站的站台轨道是现有的,因此无法达到客户需求说明(SON)中规定的最小偏移量。车站顶棚的作用荷载能力有限,因此无法支持架空线路设备(OLE)。马来西亚的标准偏移值为 3.0 米,而 KTMB 准则规定的最大偏移值为 3.60 米,最小偏移值为 2.60 米。为评估桅杆偏移量,收集了 JB Sentral 建筑数据。Sicat Master 仿真和横截面图可用来根据收集到的数据确定适当的最小偏移量。结果表明,位于两条轨道中心的桅杆可在轨道中心线与混凝土桅杆面之间的最小偏移量为 1.80 米的情况下实现净空。这些结果还表明,在列车速度较低的情况下,轨道切线可实现 1.80 米的最小偏移量。

Drug metabolism in the human liver initiated by Cytochrome P450 (CYP450) has been widely acknowledged. They oxidise drugs, harmful compounds, and endogenous molecules like steroids. In our research study, we mainly focused on CYP3A4 of the CYP450 subfamily that is widely available in the liver around 15% - 20% of hepatic content and plays a significant function in metabolising up to 50% of drugs in the market today. However, the CYP3A4 gene encodes CYP3A4 enzymes that are highly polymorphic, which could affect enzymatic activity and cause variable responses in drug metabolism. Clustered Regularly Interspaced Short Palindromic Repeats Associated Protein 9 also known as the CRISPR-Cas9 system is a gene editing method that allows scientists to edit parts of the genome by insertions and deletions. Hence, this method would be useful for genetic variants such as the CYP3A4 gene. The objectives of this study are to design a guide RNA (gRNA), to insert the designed gRNA into pGuide-it-Zs-Green1 vector, to quantify the purified CYP3A4-KO plasmid vector by using NanoDrop® and to transfect the constructed vector in a hepatic cell line. The methodology involved the selection of the gRNA by using the online gene editing tool, Synthego (https://design.synthego.com), annealing oligos of the gRNA for CYP3A4, cloning gRNA into a plasmid vector, isolation, and purification of the CYP3A4-KO plasmid vector. The construction of the CRISPR-Cas9 targeting vector in this study was successfully achieved and promising since the selected gRNA for CYP3A4 gene which is 5’-ATAAATCCCACTGGACCAAA-3’ and located in exon 5 was correctly ligated after the confirmed with sequencing reaction and cloned it into a plasmid vector. The yield of pCYP3A4-KO plasmid DNA was a good candidate for transfection.
由细胞色素 P450(CYP450)引发的药物在人体肝脏中的新陈代谢已得到广泛认可。它们能氧化药物、有害化合物和类固醇等内源性分子。在我们的研究中,我们主要关注的是 CYP450 亚家族中的 CYP3A4,它广泛存在于肝脏中,约占肝脏含量的 15%-20%,在代谢当今市场上多达 50% 的药物方面发挥着重要作用。然而,CYP3A4 基因编码的 CYP3A4 酶具有高度的多态性,这可能会影响酶的活性,导致药物代谢的不同反应。Clustered Regularly Interspaced Short Palindromic Repeats Associated Protein 9 又称 CRISPR-Cas9 系统,是一种基因编辑方法,允许科学家通过插入和删除来编辑基因组的某些部分。因此,这种方法对 CYP3A4 基因等遗传变异非常有用。本研究的目的是设计一种引导 RNA(gRNA),将设计的 gRNA 插入 pGuide-it-Zs-Green1 载体,使用 NanoDrop® 对纯化的 CYP3A4-KO 质粒载体进行定量,并将构建的载体转染肝细胞系。该方法包括使用在线基因编辑工具 Synthego (https://design.synthego.com) 选择 gRNA、退火 CYP3A4 的 gRNA 寡聚物、克隆 gRNA 到质粒载体、分离和纯化 CYP3A4-KO 质粒载体。本研究成功地构建了CRISPR-Cas9靶向载体,因为所选择的CYP3A4基因gRNA为5'-ATAAATCCCACTGGACCAAA-3',位于第5外显子,经测序反应确认后正确连接并克隆到质粒载体中。获得的 pCYP3A4-KO 质粒 DNA 是转染的理想选择。

Distributed Denial of Service (DDoS) attacks, which adversely impact network availability, confidentiality, and integrity, represent a persistent threat. These attacks involve affected systems consuming resources through spurious requests instead of serving legitimate clients. Various methodologies exist for detecting and mitigating DDoS attacks, with Machine Learning (ML) emerging as a particularly effective approach due to its predictive capabilities after training on pertinent data. The primary objective of this study is to identify an improved ML algorithm for the detection of multiple DDoS types, considering metrics such as accuracy, precision, recall, and training time. Leveraging WEKA tools and the CICDDoS2019 dataset, several machine-learning algorithms, including Multilayer Perceptron, Reduced Error Pruning (REP) Tree, Partial Decision Tree (PART), RandomForest, and J48, were trained and evaluated. Among these, J48 was determined to be the superior algorithm for classifying four DDoS types (UDP, SYN, Portmap, MSSQL), based on the aforementioned criteria. The algorithms were experimented with using diverse sets of features, and optimal results were obtained using six features, resulting in an overall accuracy of 99.97%. Subsequently, the selected algorithm was integrated into a real-time model, exhibiting exceptional performance, which will be thoroughly elucidated and discussed in a forthcoming paper.
分布式拒绝服务(DDoS)攻击会对网络的可用性、保密性和完整性造成负面影响,是一种持续存在的威胁。这些攻击涉及受影响的系统通过虚假请求消耗资源,而不是为合法客户提供服务。目前有多种方法可用于检测和缓解 DDoS 攻击,其中机器学习(ML)是一种特别有效的方法,因为它在对相关数据进行训练后具有预测能力。本研究的主要目的是确定一种用于检测多种 DDoS 类型的改进型 ML 算法,同时考虑准确率、精确度、召回率和训练时间等指标。利用 WEKA 工具和 CICDDoS2019 数据集,训练并评估了几种机器学习算法,包括多层感知器、减误剪枝(REP)树、部分决策树(PART)、RandomForest 和 J48。其中,根据上述标准,J48 被认为是对四种 DDoS 类型(UDP、SYN、Portmap、MSSQL)进行分类的最佳算法。使用不同的特征集对算法进行了实验,使用六个特征获得了最佳结果,总体准确率达到 99.97%。随后,选定的算法被集成到一个实时模型中,表现出卓越的性能,我们将在即将发表的论文中对此进行深入阐释和讨论。
