Quantifying acoustic performance and embodied carbon of acoustic solutions for mass timber buildings: Comparing common approaches around the globe

As mass timber continues to increase in popularity as a building method to shifting away from high embodied carbon concrete structures to utilize wood as a renewable and lower embodied material. As whole building life cycle assessments (LCA) become more essential in meeting environmental emissions targets and qualifying for sustainability linked financing, quantifying the embodied carbon of both the structure and all other elements is necessary. The acoustic challenges of mass timber have been well documented and studied in previous works with a range of solutions now commonly utilized. Like most elements of construction, regionality results in different techniques being more popular and practical in different parts of the world. This work will compare the airborne and structure borne sound transmission and associated embodied carbon of four common acoustic designs for mass timber construction: floating concrete toppings, isolated board and batten floor systems, isolated dry floor linings, and raised access floors.

The IPO System of the Science and Technology Innovation Board and the Status Quo of Enterprises

The emergence of the Science and Technology Innovation Board has brought new vitality to the capital market at a time when the global economy is full of uncertainties, the slowing of China's macro-strategic economic growth, and rising pressure for structural adjustment and transformation. However, the STAR Market provides investors and businesses with more opportunities, resources, and specific risks. In China, registered production is a new issuance and listing system. China needs more trial and error to learn and get out of China's model for mature systems in countries such as the United Kingdom and the United States. The impact of the Sci-tech Innovation Board's registration system on the Chinese company listing system and the entire capital market is currently the focus of attention and research. The current immature registration system also introduces numerous unknown risks. Through a review of the literature, this paper mentions the industry development opportunities provided by the current science and technology innovation board and registration system, including its existing risks and flaws.

Does gender diversity improve CSR reporting? Evidence from the Central and West Balkan banking sector

This study aims to investigate the effect of gender diversity in board of directors in banks on environmental, economic, social, and governance (CSR) reporting. The sample comprises 85 banks operating in the Central and West Balkan region. Research results suggest that gender diversity in a two-tier board system in bank boards does not affect CSR reporting as measured by the constructed EESG index with statistical significance. However, taking into consideration specific elements of this index, we found that gender diversity on the supervisory board had a positive effect on variables that compose this index. This is the first study to provide insight into gender and the CSR reporting nexus in the Central and West Balkan region. This study contributes to the discussions on those issues in a global scale and in terms of the banking sector in particular.

A probabilistic bottom-up modelling approach for synthetic load profiles within the energy efficiency management of cruise ship cabins

A reliable estimate of the electrical demand is a decisive factor in the design of electric board systems on cruise ships. This applies to all areas of the ship, including the hotel area with its up to several thousand cabins, which account for a non-negligible share of the total energy demand. In this paper, a simplified bottom-up model that can depict the electrical demand cabins with high temporal resolution and thus support marine and electrical engineers in developing future on-board power grids is presented. Key-card data will be used as a basis to easily access the behaviour of passengers on board. Another benefit is that the key data of the electrical consumers can be easily adapted to different types of ships and cabins. By including the ships route it is possible to precisely calculate the heat input through the glazing at any time of day and to determine its effect on the air-conditioning requirement. The model presented here is therefore not limited to certain regions but can be used globally. The functionality of the model is demonstrated on the example of a Caribbean cruise where the average electrical demand of a cabin is determined to 1.6 kWh per day.

Analysis of COVID-19-Related User Content on the Baseball Bulletin Board in 2020 through Text Mining.

The world engaged in online sport watching during COVID-19. Fortunately, in Taiwan, the pandemic was stably controlled in 2020, allowing for the continuation of the Chinese Professional Baseball League (CPBL); this attracted international attention and encouraged relevant discussions on social media in Taiwan. In the present study, through text mining, we analyzed user content (e.g., the concepts of sports service quality and social identity) on the Professional Technology Temple (PTT) baseball board-the largest online bulletin board system in Taiwan. A predictive model was constructed to assess PTT users' COVID-19-related comments in 2020. A total of 422 articles and 21,167 comments were retrieved. PTT users interacted more frequently during the closed-door period, particularly during the beginning of the CPBL in April. Effective pandemic prevention, which garnered global attention to the league, generated a sense of national identity among the users, which was strengthened with the development of peripheral products, such as English broadcasting and live broadcasting on Twitch. We used machine learning to develop a chatbot for predicting the attributes of users' comments; this chatbot may improve CPBL teams' understanding of public opinion trends. Our findings may help stakeholders develop tailored programs for online spectators of sports during pandemic situations.

TEMPERATURE CONTROL OF ELECTRIC FURNACE USING PID CONTROLLER BASED GWO ALGORITHM AND FPGA IMPLEMENTATION

ne of the critical characteristics that must be regulated in today's industry is temperature. It is crucial that this temperature regulation must be exact and quick. Since they are not adjusted to their full capability, the controller that used to manage the performance of the electric furnace's temperature is no better than that of the conventional controllers. It has a significant amount of overshoot and excessively long rising and settling times. This work introduces a PID controller based on the Grey Wolf Optimization Algorithm (GWO) so that to address the PID controller's low accuracy, long rising time, and long settling time. Additionally, Field Programmable Gate-Array (FPGA) is used to execute the suggested control scheme because of its large data storage capacity, low energy consumption, and quick operation. Due to their accessibility, the Spartan-6 (XC6SLX45T-3FGG484) board and Xilinx system generator blocks are used in the simulation. The results stated that the proposed approach is faster and more settle in tuning PID parameters and also the overshoot was lower; thus, it outperformed on the traditional methods.

Consensus Statements on Precision Oncology in the China Greater Bay Area.

Next-generation sequencing comprehensive genomic panels (NGS CGPs) have enabled the delivery of tailor-made therapeutic approaches to improve survival outcomes in patients with cancer. Within the China Greater Bay Area (GBA), territorial differences in clinical practices and health care systems and strengthening collaboration warrant a regional consensus to consolidate the development and integration of precision oncology (PO). Therefore, the Precision Oncology Working Group (POWG) formulated standardized principles for the clinical application of molecular profiling, interpretation of genomic alterations, and alignment of actionable mutations with sequence-directed therapy to deliver clinical services of excellence and evidence-based care to patients with cancer in the China GBA. Thirty experts used a modified Delphi method. The evidence extracted to support the statements was graded according to the GRADE system and reported according to the Revised Standards for Quality Improvement Reporting Excellence guidelines, version 2.0. The POWG reached consensus in six key statements: harmonization of reporting and quality assurance of NGS; molecular tumor board and clinical decision support systems for PO; education and training; research and real-world data collection, patient engagement, regulations, and financial reimbursement of PO treatment strategies; and clinical recommendations and implementation of PO in clinical practice. POWG consensus statements standardize the clinical application of NGS CGPs, streamline the interpretation of clinically significant genomic alterations, and align actionable mutations with sequence-directed therapies. The POWG consensus statements may harmonize the utility and delivery of PO in China's GBA.

When Digital and Physical World Combine: The Metaverse and Gamification of Violent Extremism

From early Bulletin Board Systems adopted by neo-Nazis to the Islamic State’s more recent prolific use of social media platforms, an aspect of terrorism studies that is generally agreed upon is that violent extremists are often early adopters of emerging technologies. These groups, organisations, and networks have demonstrated innovative uses of these digital spaces, harnessed for recruitment, coordination, community building, attack planning, propaganda dissemination, and other purposes. Alongside studying these phenomena, it is important to explore where future trends lie; particularly as findings and recommendations can ensure that relevant stakeholders are aware of and can begin to prepare for emerging threats. This paper considers the potential exploitation of Web 3.0, specifically the metaverse, by violent extremists and explores conceivable opportunities to undertake nefarious activities within these spaces. There is a particular focus on the gamification of violent extremism in the metaverse, an issue—i.e. the gamification of violent extremism—that is causing increasing concern to terrorism practitioners more generally. Although it is difficult to predict exactly how violent extremists will utilise, exploit, and misuse the metaverse and related technologies due to the early stage of its conceptualisation and development, it is possible to develop hypotheses based on past trends and current examples demonstrating manipulation of online spaces that resemble aspects of the metaverse. In fact, aspects of the gamification of violent extremism in the metaverse may well have distinct overlaps with current threats, but simply utilise emerging technologies and take place within developing and more immersive online spaces.

Analysis of cooling performance and energy consumption of nocturnal radiation and natural ventilation combined mechanical refrigeration system for outdoor prefabricated substation

To make full use of renewable energy and reduce cooling energy consumption, a new structure nocturnal radiation board was designed, modeled and experimentally studied, and a combined refrigeration system of air/water-cooled chiller, nocturnal radiation board and natural ventilation unit was proposed and simulated with the building model of a prefabricated substation in Zhenjiang city in China. The research results of the nocturnal radiation board show that the average cooling heat fluxes are about 40.24, 70.40 and 37.84 W/m2 on a typical sunny summer day, a cool autumn day and a rainy summer day, respectively. The average cooling heat flux ratio of experimental results to calculating results is about 0.75, which can be taken as the model modification coefficient to predict the cooling heat flux of the nocturnal radiation board. The hourly dynamic simulation results of the combined refrigeration system show that the energy saving rates of 37.65%, 44.80% and 62.24% can be achieved on a typical summer day, a cool autumn week and the whole year when compared with the conventional air-cooled chiller system. The annual coefficient of performance of the combined refrigeration system is about 15.31, which is more than 2.7 times that of the conventional air-cooled chiller system. The proposed nocturnal radiation board and combined refrigeration system can make full use of nocturnal radiation energy and air energy for space cooling and significantly reduce the cooling energy consumption.

Stable electrospray signal on a microfabricated glass chip with three-dimensional open edge and tiered depth geometries

This paper presents the microfabrication and performance of a three-dimensional electrospray ionization (ESI) emitter tip made from glass, which achieves stable current signals important for chemical analysis. Our novel microfabrication process and custom-built signal conditioning hardware provides the advantage of providing accurate features and steady signals. The fabrication process relies on standard microfabrication techniques (i.e., deposition, photolithography, and wet etching). This fabrication method involves the novel application of two layers of positive and negative photoresists in addition to Parafilm® wax tape. Open edge and tiered depth details were successfully created from a multilayer planar mask. This is a benefit for integrated miniaturized and microfluidic systems that often require micro features for their functionality but relatively large millimeter size features for their physical periphery. We demonstrate the fundamental performance of electrospray with this microfluidic chip. The emitter tip was fixed on a linear axis stage with high resolution (10 μm) to finely control the tip distance from a metal counter electrode plate. A custom printed circuit board system was built to safely control four voltages applied to the microchip ports from a single high voltage power supply. To readily form the electrospray, non-aqueous solvents were used for their low viscosity and a constant voltage of +2.7 kV was applied to the sheath electrospray microchannel. The liquid being sprayed was 80/20 (v/v) methanol/acetonitrile with 0.1% acetic acid in the sheath microchannel and with ammonium acetate (10–40 mM) in its remaining microchannels. The electrospray signal was measured in response to varying the distance (1.4 to 1.6 mm) between the electrospray emitter tip and a metal counter electrode plate in addition to the varying concentration of the background electrolyte, ammonium acetate. Stable and repeatable electrospray signal showed linear relationships with emitter tip distance and concentration (r2 ≥ 0.95).

"PERFORMANCE ANALYSIS OF INERT GAS PLANT WITH SCRUBBER USING ANSYS FOR A VLCC SHIP"

"Through the 1978 SOLAS Protocol and then through the introduction of amendments from 1981 and 1983, new specifications are brought regarding the design, operation, maintenance, verification of inert gas systems intended for both oil tanks and bulk chemical tanks, and, in general, the systems of safety on board ships carrying dangerous goods. The inerting method using a gas system with generator and scrubber involves a continuous and very efficient process, with a low level of supervision and maintenance, that is why this type of installation was chosen in this study. Installations with a scrubber type unit require the installation of an inert gas generator that operates at a pressure of 8-10 bar and releases nitrogen at 7-9 bar. The quality of the air will depend on the type of generator used, scrubber type unit, but air without impurities with the best possible quality is recommended. Nitrogen quality for a given unit varies with production rate and is generally 95-97% pure. By connecting high-quality scrubbers, nitrogen can be brought to 99% purity, but at lower production rates and much higher energy consumption rates of any system on board ship is specifically identified with its reliability. So as to get the best out of marine motors, it is critical to screen their performances and take measures to accomplish productive combustion. As a result of heat gains on board ships from engine rooms and crew, the increase in humidity as well as due to the various releases of gases from on board systems, room air deteriorates, requiring replacement and its processing through the HVAC (heat, ventilation and air conditioning) system. The combustion process in diese."

PERFORMANCE IN SOE TWO TIERS BOARD SYSTEM BASED ON THE IMPLICATION FROM GOOD CORPORATE GOVERNANCE AND TUNNELING OR PROPPING THROUGH RELATED PARTY TRANSACTIONS

This study is to provide empirical evidence about the performance of State-Owned Enterprises in Indonesia with a two-tier board system, on the effect of GCG and tunneling or propping through related transactions. This research uses data in the form of annual reports of State-Owned Enterprises. The results of this study showed that 69% were showing related transactions indicated tunneling and 31% showed related transactions indicated propping. Furthermore, the results obtained that the performance was simultaneously affected by GCG and tunneling. Partially GCG has a positive effect on performance, while tunneling or propping does not affect. The limitation of this research is that there are only 22 state-owned companies whose shares are partly owned by the public, during 2014-2019. The implication is that SOE need to continue to improve GCG to improve SOE’s performance, so that the possibility of tunneling which is a form of detrimental control can be minimized. This study shows that tunneling in state-owned companies is not in the form of taking cash or assets, but taking profits through control, coercion, and regulation. This study uses the performance measure based on the Malcolm Baldridge criteria.

Laser Doppler vibrometry-based measurements on viscoelastic panels for flexural damping properties

Bending wave propagation is of central importance when enhancing sound transmission losses of sandwiched wall board systems incorporating viscoelastic panels as constrained damping layers. The damping properties of constrained damping layers made of viscoelastic materials can often be characterized by bending wave excitations. However, the multifactor, dispersive nature of the bending waves leads to challenges in reliable dynamic material characterization. To better understand the damping mechanism of the constrained damping layers, an experimental methodology employing complex bending wave theory has been developed to determine these flexural wave properties, including the loss factor and the bending stiffness of highly viscous panels. Relying on a transfer function from the experimentally measured bending velocities between two locations radially away from a flexural wave exciter on the viscoelastic panel under test, this methodology yields the broadband bending loss factor, the bending phase speed, and the bending stiffness. This paper discusses the experimental method for characterizing the above properties from laser Doppler vibrometry-based measurements of bending velocities. This paper also discusses the challenges with this method as well as an approach to mitigate the challenging effects and improve measurement accuracy.
