Authors: He Pengfei
Published: November 2023

Green roofs and cool roofs are considered to improve energy efficiency, and provide economic benefits, energy-saving benefits, environmental benefits for the traditional grey roofs. Some national and local standards have analysed and recommended these technologies in existing building renovations, but their research subjects were mostly office or residential buildings, which didnt include the evaluation and analysis of specific roof renovations in different thermal zones in the United States. This paper conducted a 40-year life cycle cost analysis of retail buildings roofs in 16 cities across 8 different thermal zones in the United States. LCCA found that cool roofs showed a positive life cycle NPV in all cities, while green roofs showed a negative NPV. This article also analysed and compared the environmental benefits of retail buildings roofs in 16 cities, and calculated the emission reductions that they can bring to power plants. This paper also selected retail buildings roofs from 8 representative cities in 8 different thermal zones for energy savings and cost savings analysis. The results show that decision-makers can transform ordinary roofs into green roofs or cool roofs according to the characteristics of each thermal zone, combined with energy-saving benefits, economic benefits, environmental benefits and other factors, which is conducive to the implementation of new specifications.
How the surrounding multi-scale building clusters affect the wind loads of the super high-rise building
Authors: Li Zhifei , Sun Zhibin
Published: November 2023

Many super high-rise buildings emerge in modern cities with urban development, facilitating work, accommodations, etc. However, their safety risks and accidents due to the wind are urgent problems with the complex flow field in cities. The research on wind loads of super high-rise buildings is thus crucial, but most studies tend to consider only the influence of the surrounding single-scale building clusters, rarely considering multi-scale ones. In this paper, the influence of the surrounding multi-scale building clusters on the wind loads of a super high-rise building is investigated. The wind field of a super high-rise building surrounded by four different arrangements of idealized, simplified buildings is first simulated using computational fluid dynamics (CFD) methods: RANS and Hybrid LES/RANS models. It is found that surrounding tall buildings can significantly affect the pressure distribution on the windward and leeward sides of the super high-rise building, such as fluctuating, extreme, and mean wind pressure. The vortex, formed largely due to short buildings, increases the negative pressure at the back of the super high-rise building. In addition, simulations are conducted for the wind field around the CITIC Tower in Beijing CBD, and it is found that the flow field of the actual building group is more complex due to the strong interactions between buildings, and the flow near the ground is even more complex. All simulation results are validated by the wind tunnel tests. This study can provide important guidance for the wind safety design of super high-rise buildings and the future planning of urban buildings.

Authors: Zhao Yiheng
Published: November 2023

GaN is a third-generation semiconductor. As an ideal material of the new generation semiconductor today, it has many features such as high saturated electron mobility and wide band. The methods of GaN growth developed rapidly recently. We reviewed recent artiles and then we collect the various of methods about the GaN single crystal growth, after that we compare the difference among these method. This paper mainly talks about three methods of growing GaN single crystal: The Ammonothermal method, the Sodium-flux growth method, and the Halide vapor phase epitaxy (HVPE), and we collect both of the advantages and disadvantages. By putting all characteristics of each methods together we found that combining the HVPE method and Ammonothermal method together can connect the advantages together and avoid some of these disadvantages. We can use the HVPE method to grow the GaN seed and expand the crystal using the Ammonothermal method may be a good choice to grow the GaN single crystal at a low cost. Because if we start with Ammonothermal method, it is easy to form the polycrystalline and if we use the HVPE method to grow large crytal, it is too expensive to do so. Therefore, combining two methods can avoid the disadantages in each other and save the cost when growing.

Authors: Han Renwu
Published: November 2023

Due to its high specific capacity, silicon anode has gained interest on a global scale as the anode of next-generation lithium-ion batteries (LIBs). However, it is challenging for silicon anodes to replace graphite anodes for widespread use due to the inevitable volume expansion and SEI film development generated by silicon during the lithiation/delithiation process. Among these, the advancement of nanotechnology has sped up the development of silicon anodes. This paper reviews nanotechnology applied in the Si anode to improve the battery performance. The volume expansion of Si is effectively decreased by reducing the volume of the silicon anode in order to increase its specific surface area. Additionally, the smaller negative electrode reduces the distance traveled by lithium ions, greatly increasing the silicon negative electrode's efficiency. At present, the main silicon nano-anode materials include nanoparticles, nanowires, nanosheets, nanotubes, nanoporous materials and so on. It is hoped that this review will provide a deep prospect introduction to the nano-silicon anode. Pure silicon nanoparticles and silicon nanowires, and new nanomaterials composed of them with graphite, graphene, metals, etc.

Authors: PAKOLPAKIL Ayben
Published: November 2023

Noise pollution is becoming more prevalent, and it is currently the world's third most serious pollution problem. In recent years, nanofibers have achieved great interest in acoustics applications for noise control. Electrospun nonwovens can enhance acoustic insulation goods by enhancing the sound absorption coefficient, reducing material thickness, and diminishing material weight, giving them a strategic advantage. Polylactic acid (PLA) polymer has sparked a lot of attention as a potential textile material for a sustainable future. In this study, nonwoven mats of PLA were prepared by electrospinning with various amounts of deposition time (30, 60, and 120 min). The electrospun layers was coated on the PP nonwoven and used samples with different thicknesses of textile materials. The measurements of the absorption coefficient have been performed with the impedance tube in the frequency range of 500 Hz-6400 Hz. The test results were compared with measurements carried out on PP nonwoven without the layer of nanofibers. Electrospun samples that are quite thin were found to be particularly effective at high frequencies. This study demonstrated that the sound absorption property of a textile material that does not have sound-absorbing properties could be improved simply by coating with electrospinning using PLA polymer.

Informal Cross-Border Trade: Malaysia-Indonesia Borders The Conceptualisation From ‘Authority-Defined’ To "Everyday-Defined"
Authors: Sarjono Fauzie , Rudiatin Endang
Published: November 2023

For these border studies, understanding borderlanders provides a new narrative about boundaries. The history of a nation-state of a collective nature, the alignment of power, economic segmentation, and integration of culture, ethnicity, and identity, religion, the behavior of marginal communities, as well as modern socio-political segregation are variables that can be raised in various disciplines. In this study, we offer a qualitative method with an ethnographic perspective, as many anthropologists do, but with a constructivist approach. We call it the conceptualization of "Authority-Defined" to "Everyday-Defined." The diversity of narratives and connotations in unraveling boundaries gives the perspective of contextual interpretation in different positions. Surely, understanding boundaries should also be seen in such a detailed context that the actors of border studies, i.e., society, are observed through the lens of meaning boundaries in their everyday lives. These differences lead to findings that are rich in dynamic and varied border backgrounds. This discussion focused on on-the-ground findings about informal cross-border trade, specifically at the Malaysia-Indonesia border. A trading system built by local communities is certainly different from the trade system in non-border areas and even in the country's capital area.

Published: November 2023

The field of computer vision and pattern recognition has shown great interest in facial recognition due to its wide range of applications. These applications span across historical and genealogical research, forensic science, searching for missing family members, analyzing social media, automatically managing and annotating image databases, and identifying kinship relationships. This research paper aims to address the challenges associated with facial recognition by introducing two innovative approaches: Fusion-based Classifier Combination (FCC) and Sequential CNN Deep learning-based face recognition (S-CNN). In the first part of the study, we assess the effectiveness of three techniques: Local Binary Patterns (LBP), Histogram of Oriented Gradients (HOG), and a hand-crafted learned technique called Compact Binary Facial Descriptors (CBFD). To overcome these challenges, we employ a classification step that utilizes a novel multi-classifier combination model. In the second part, we propose a novel method where we extract high-level features from multiple image regions treated as sequential data using ensemble of Convolutional Neural Networks (CNNs). These features are then fed into a Deep Neural Network (DNN) for facial recognition. The experimental results obtained from well-known face databases, including Labeled Faces in the Wild (LFW) and ORL, highlight the competitive performance of both the proposed multi-classifier combination model and the S-CNN deep learning model when compared to state-of-the-art methods .
LongCGDroid: Android malware detection through longitudinal study for machine learning and deep learning
Authors: Mesbah Abdelhak , Baddari Ibtihel , Raihla Mohamed
Published: November 2023

This study aims to compare the longitudinal performance between machine learning and deep learning classifiers for Android malware detection, employing different levels of feature abstraction. Using a dataset of 200k Android apps labeled by date within a 10-year range (2013-2022), we propose the LongCGDroid, an image-based effective approach for Android malware detection. We use the semantic Call Graph API representation that is derived from the Control Flow Graph and Data Flow Graph to extract abstracted API calls. Thus, we evaluate the longitudinal performance of LongCGDroid against API changes. Different models are used, machine learning models (LR, RF, KNN, SVM) and deep learning models (CNN, RNN). Empirical experiments demonstrate a progressive decline in performance for all classifiers when evaluated on samples from later periods. Whereas, the deep learning CNN model under the class abstraction maintains a certain stability over time. In comparison with eight state-of-the-art approaches, LongCGDroid achieves higher accuracy.

This study aims to develop a formulation with the active ingredient Stichopus hermanii for antidiabetic treatment or function to lower blood glucose levels. The formulation approach taken is to design a formula in the form of solid lipid nanoparticles (SLN), where this system is expected to optimize absorption and improve the performance of the active substance. The SLN characterization includes particle size measurement, zeta potential, polydispersity index analysis, and morphology analysis using TEM. The antihyperglycemic activity test will be tested in vivo using male white rats using the glucose tolerance test method and induced by streptozotocin. The results of the TEM analysis showed that the sea cucumber spherical in shape. The particle size of the formula was found to be 0.25 nm. The polydispersion index (PDI) of the formulation was 67.5%, 2%, and 0.5%, respectively. In the same test, male rats were given treatment according to the group division, namely 50% glucose at a dose of 3 g/kg bw 30 minutes later and the blood sugar levels were measured at 30, 60, 90, and 120 minutes using a glucometer. In a follow-up test, the administration of test samples (days -3, 6, 9, 12, and 15) of CMC Na, metformin, and 25 mg/kg body weight of the test group showed that blood sugar level decreased with the highest decrease in positive control group. In conclusion, the results showed that sea cucumbers could be developed as a functional food product to help battle the onset of diabetes and diabetic complications.
