    Wire bonding is the preferred interconnection in the IC packaging. Understanding the electrical performance of bonding wire as transmission line is utmost important. To date, there are very limited studies on the transmission performance of fine pitch bare bonding wire especially the insulated wires. This paper investigated the transmission performance of single bare bonding wires and insulated bonding wires with different wire material, wire diameter, bonding height and insulation thickness at high frequency. The simulation analysis shows that when the frequency increases above 15 Ghz, the effect of geometric parameters has no significant difference to the transmission performance. The thickness of the insulation between 0.1 ?m to 0.3 ?m demonstrated similar performance for return loss and insertion loss across all frequencies. � 2023 Trans Tech Publications Ltd, Switzerland.

    Kitchen cabinets started to have a big historical impact on Malaysia in the nineteenth century. The drawback with traditional costing methods is that they fail to offer enough information that are crucial to customers, such quality and service. Activity-based costing (ABC) was created to address traditional costing?s limitations in complex product environments. However, it is not universally accepted as it overlooks unused capacity for forecasting. This work compares ABC and time-driven ABC (TDABC) to assess cost sustainability in kitchen cabinet production by determining the cost driver rate and analyzing unused capacity of time and cost, respectively. Data from a Johor-based furniture manufacturer was collected. The work successfully compares both methodologies, considering various factors. Ultimately, the forecast cost and capacity utilization in kitchen cabinet production have been determined. By applying ABC method, a single unit of kitchen cabinets is predicted to cost as much as MYR 3426.32. Whereas in TDABC, the unused capacity of time and cost are ?5208.80�min and MYR ?2838.32, accordingly. It concludes that both have strengths based on industry needs, but proving TDABC?s efficiency is essential as it is simpler, cheaper, and more powerful than ABC. Nonetheless, neither ABC nor TDABC is well-suited for kitchen cabinets manufacturing. The process of building kitchen cabinets involves inherent complexity, such as variations in measurements, material availability, and design specifications. Based on the given factors, such as higher uncertainties, biases in assumptions and inaccurate data collection, it will draw limitations in obtaining accurate and reliable data for ABC and TDABC. ?

    Landslides can cause disastrous flooding, particularly when streams in the dams are breached by landslide which increases water level and may trigger more slides. This study aims to identify potential landslide zone and its characteristics through landslide hazard mapping using the Geographical Information System (GIS). The importance of precipitation toward the result will also be evaluated using different percentages of influences. Elevation, slope angle, slope aspect, and geology are the variables considered. The susceptibility map was generated by analyzing each factor using the weighted overlay method. The susceptibility map combined with precipitation data generates a Landslide Hazard Map. In the weighted overlay process, assigning different percentages of influence for precipitation resulted in different landslide hazard (LH) zones. The outcome, based on a 55% influence factor, showed that 95.5% of the area was identified as a low hazard while the remaining area was classified as a moderate hazard. In contrast, by using 45% influence, 45.1% area is moderately hazardous followed by lower hazard. Increasing the percentage of influence by more than 55% showed no changes to the LH result. Damage at the dam area will disrupt energy production in the area. Besides urban area, management and monitoring of slope stability in the study area is vital, particularly during unpredictable weather changes. � The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.

    Araucaria Araucana starch is a raw material with proven potential in obtaining biodegradable polymers. Plasticization improves the flexibility characteristics of starch-based films, however, they still tend to have low tensile strength and high hydrophilicity. The addition of nanocellulose is a technique to improve these characteristics. In this paper, the effects of adding different sources and concentrations of nanocellulose (NC) on the properties of thermoplastic Araucaria Araucana films are addressed. One can highlight, the main effects are the increase of tensile strength and transparency of the films along with the reduction of water vapor permeability and water solubility. Further studies involving the reinforcement of Araucaria Araucana starch and nanocellulose should be conducted to overcome the lack of information. � 2023 Walter de Gruyter GmbH, Berlin/Boston.

    Perak State, located in the Northern Corridor of Peninsular Malaysia, offers attractive spots and ecotourism sites for tourists to explore. The state is also campaigning for Visit Perak 2024 to promote tourism as a strategic economic sector that will significantly contribute to Gross Domestic Product (GDP), job creation and foreign exchange earnings. However, Perak has been experiencing devastating flood incidences, including flash floods in the last three years (2020�2022). This article aims to assess the potential impacts of dam-break flood disasters towards the tourism industry in the Hulu Perak district of Perak, with a focus on the socio-economic values. As a methodology, primary and secondary data have been collected from in situ interviews with local authorities, Department of Statistics Malaysia (DOSM) Perak and relevant published annual statistical reports. This study has found that, in the event of a dam break or flood caused by excessive rainfall, the tourism industry and other supporting hospitality industries in Hulu Perak district will be adversely affected by loss of revenues and negative socio-economic implications. In view of these potential hazards, this study has recommended an integrated flood impact analysis to be undertaken at the state level to create a tourist contingency strategy for flood recovery. � The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.

    This paper aims to assess the subsurface integrity and stability of the slope in the Pergau-Batu Melintang electrical energy production area, located on a highland and near the slope edge, which may pose a risk. Two geophysical survey techniques were used to evaluate the slope's stability: electrical resistivity and seismic survey through in situ testing. The electrical resistivity test has the advantage of producing both subsurface resistivity and the ground's resistivity index. Meanwhile, the seismic survey aimed to identify any subsurface homogeneity. This study assessed the slope stability due to rock weathering by combining in situ testing, geophysical survey, laboratory testing, rock quality designation (RQD%), standard penetration test (SPT) N values, and macroscopic and microscopic rock identification. Slope-W software was used to simulate and determine the slope's Factor of Safety (FOS). The FOS results indicate that the method utilised in this study offers a promising discovery and a correlation between the impact of weathering processes and slope instability. � The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.

    The conversion of biowaste into bioethanol, which possesses biodegradable properties, low toxicity, and is a renewable resource, is regarded as a promising clean fuel technology. It is anticipated that the annual production of bioethanol will surpass 7 billion gallons. This chapter focuses on the design of the production process for bioethanol, encompassing pretreatment and enzymatic hydrolysis. The anticipated properties of bioethanol, based on various process parameters and operating conditions, are examined, as these factors influence the calorific value and autoignition temperatures of bioethanol. The chapter further explores the steps involved in process design, including glycolysis, acetaldehyde production, glycolysis, and protonation of ethanol through the use of hydrogen ions. The performance of bioethanol is assessed in comparison to other fossil fuels. In terms of environmental impact, the emission of bioethanol ranges from 23 to 85 g CO2eq/MJ, which is 75% lower than that of fossil fuels. Biomass is categorized into forest biomass, biorenewable waste, energy crops, and aquatic biomass feedstock. Various fermentation techniques, such as liquid-state fermentation, solid-state fermentation, and gravitational fermentation, are evaluated for their impact on bioethanol yield. Additionally, different fermentation methods, including liquid-state fermentation, solid-state fermentation, and gravitational fermentation, are assessed for their performance. Bioethanol has also been utilized as an additive to fossil fuels, enhancing evaporative temperatures and reducing volatility, thus improving ignition properties. ? 2024 Elsevier Ltd.

    Recent research has identified that the major fraction of kinetic model in any type of wastewater. The research presented herein develops the kinetics of low-loading wastewater removal and river water treatment plant as a launch pad. Kinetic laboratory was developed with the setup of 2-h hydraulic retention time (HRT) in integrated Fixed Activated Sludge System (IFAS) bioreactor operation toward biological performance. Two bioreactors were installed with two different types of biological carrier which was applied in full-scale RWTP and was fed with synthetic river water. The setting-up including concentration of the carrier was followed the manufacturer�s design same as full-scale RWTP. The testing happened for 28�days non-stop. In biological kinetic parameter estimation, according to the Monod model, it can be observed that values obtained for biokinetic coefficients for brush media and Bioball are k as 4.65�days?1 and 1.37�days?1 while ?max as 5.11�days?1 and 1.424�days?1 respectively. The model validation test and bio-kinetic parameters of brush media models have shown better simulation results compared to Bioball bio-kinetic parameters. This was proven with root mean square error (RMSE) value (8.26) for brush media, which is lesser than 47.1369 RMSE value (29.08). These findings provide evidence of the best performance and operation of RWTPs

    Biopolymers and their nano-structured analogs play a vital role in hindering an issue of feedstock lack and in generating an eco-friendly environment. A fast-evolving multidisciplinary science known as nanotechnology enables the manufacturing of polymers at the nanoscale scale for various medical applications. As compared to synthetic ones, biopolymers used in biomedical applications ensure biocompatibility, biodegradability, and minimal immunogenicity. A biopolymer such as silk fibroins, collagen, gelatin, albumin, starch, cellulose, and chitosan can be readily produced into suspensions which act as carriers for dual-large and small medicinal molecules. The techniques, commonly used to make the biopolymer, include spray-drying, electrospraying, desolvation, supercritical fluid extraction, layer-by-layer self-assembly, freeze drying, and microemulsion for different applications in medicine such as nanocarrier for drug delivery systems, tissue engineering, regenerative medicine, water treatment, energy sector, and food industry. We also discussed the various characterization techniques and importance of biopolymers in nanotechnology-based biomedical applications. ? 2024 by John Wiley & Sons, Inc. All rights reserved.

    The decarbonisation of industry based on the sustainable use of resources is one of the main objectives of our current society. To achieve this, rich-carbohydrate residual streams constitute a cost-effective feedstock from which hydrogen can be produced via dark fermentation (DF). In recent years, bench-scale testing has delivered encouraging results. Nonetheless, the low hydrogen productivity obtained still prevents the upscaling of this technology. A possible solution to overcome this technical barrier might be to couple DF with other available bioprocesses. The resulting coupling would enhance substrate exploitation and increase hydrogen productivity. The biohydrogen produced could be used either as an energetic vector or as a platform molecule for added-value compound production. This chapter aims to comprehensively review the existing bioprocesses under investigation coupled with DF as a pivotal technology for biohydrogen production. More specifically, technologies such as microbial electrolysis cells, microalgae cultivation, biomethanation, photofermentation, and lactate production are evaluated. Aspects such as the optimal operational conditions that favour the coupling in each case and the hydrogen yields obtained, are reported. Furthermore, the advantages and disadvantages of the process couplings are also discussed. Finally, current challenges and future perspectives that each hydrogen production platform entails are pointed out to set the way forward in the coming years. ?

    Recent researchers are keen on developing alternative bioplastic materials from renewable and eco-friendly sources to replace the materials obtained from crude oil and other petroleum-based sources. The measures for these replacements have been made continuously to create a sustainable future for the forthcoming generations. Researchers are focusing on bio-based alternatives due to their numerous benefits, including biodegradability, biocompatibility, nontoxicity, and structural flexibility. The main problem on the current bio-based material such as poly lactic acid, poly butylene succinate and poly L lactide, polyhydroxybuturate, and polyhydroxyalkalonates is the cost of production. Compare with cassava starch, the cost is much cheaper around 0.32 $/kg compare with other bio-based will cost around 1.2-2.4 $/kg. Conversion of biomass into useful materials has been the order of the day, as it reduces the cost of inventory and aims to develop a nature-derived material. The development of nanocomposites from biological sources has progressively experimented with the researchers and the deriving of polysaccharides such as starch, cellulose, and glycogen has aided the development of nanobiocomposites. Corn starch has been the dominant bioplastic material derived out of corn which can handle a variety of reinforcements and render a biocomposite material with better and enhanced properties. Cassava starch is the most economic and cheap polysaccharide derived from the cassava plant and has a greater potential to act as biopolymer material for the development of biocomposites. The development of cassava starch-based biocomposite film was widely used for a wide range of applications mainly for food packaging applications. This review focuses on the extraction, preparation, and properties of cassava starch from cassava plants. The properties of the cassava starch and its composites were also comprehensively dealt with. The development of biocomposite films based on cassava starch for food packaging applications has been reviewed along with the challenges associated with it. � 2023 Walter de Gruyter GmbH, Berlin/Boston.

    There is a growing interest in a diverse array of nano-biochar derived from cellulose-based feedstocks to address the most pressing ecosystem challenges nowadays. Cellulose has emerged as the primary material for the production of nano bio charcoal with distinctive ability of low-cost, abundant in nature, renewable, sustainable, and biocompatible properties. Thus, cellulose-based nanomaterials attracted the attention of the research community due to their broad-spectrum applications in the fields of agriculture, environment, catalysis, energy, and biomedical. Soil contamination by heavy metals, pesticides, herbicides, and polycyclic aromatic hydrocarbons is also regarded as one of the serious issues that implement the treatment by nano-biochar. As a result, soil remediation has been achieved through the improvement of soil fertility, enhancement of plant productivity and yield, increase in soil quality for plant growth and development, and promote carbon sequestration. Overall, this review chapter has evaluated and presented the preparation, characterization, and manufacturing technology of cellulose nano bio charcoal as natural feedstock for advanced carbon material, especially in soil remediation studies. ? 2025 Elsevier Ltd.

    Understanding community members' perceptions is the precondition for community-based disaster risk management. Although abundant research is available in existing literature assessing flood risk preparedness and its predictive perception factors, there is a lack of research assessing such a relationship for community-based dam-failure flood risk management. The study proposed a framework for assessing community members' preparedness intentions for dam-failure flood risk by reviewing existing literature on flood risk management and other disaster risk management and taking into account dominant Protection Motivation Theory (PMT) and Person Relative to Event Theory (PrE). The proposed framework will contribute to understanding preparedness intentions for dam-failure flood risk and relevant perception factors. The suggested framework is expected to contribute to pre-hazard community-based dam-failure flood risk management by aiding plan, design, and implementation of its activities such as a risk communication program, community-based awareness, and a training program. The proposed framework includes community perception factors such as worry, perceived risk, perceived self-responsibility, and perceived outcome-efficacy as the independent variables, preparedness intention (PI) as a dependent variable, and perceived self-efficacy as the moderating variable to influence the strength of the relationship between independent variables and dependent variables. � The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.

    Urbanization contributes to an increase in flood frequency and intensity, which is exacerbated by climate change. This is a phenomenon observed in both developing and industrialized countries, including Malaysia and Thailand. It is possible to lessen the devastation that natural catastrophes cause as a result of climate change by making timely and accurate predictions and being better prepared. In addition, when it comes to the general enhancement of community resilience, the utilization of effective interaction strategies between the society and the relevant agencies is an important part in the success of the endeavor. The objective of this research is to develop a real time flood modelling tool that can be put to use to lessen the likelihood of flood damage, make recommendations about climate adaptation techniques, and improve the capacity of local communities to withstand natural disasters. One case study will be conducted in Malaysia, while the other will be conducted in Thailand. These case studies will demonstrate how the developed model can reduce the impact of flooding. Two aspects of the modelling method contribute to the flexibility and resilience of the whole system which is to greatly reduce the amount of time spent on computational tasks by utilizing cloud computing�and�streamlining the process of capacity growth for relevant agencies. The findings of this study will be incorporated into the formulation of a resiliency index, which will be supported by involvement with the local community and authorities. � The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.
