Calculations of the characteristics concerning the heat exchange equipment of the Flash/ORC power plant for the usage in waste heat recovery (WHR) cogeneration plants are presented. The use of hybrid power plants with water steam and organic working fluids, on the one hand, leads to an increase in the mass of the heat exchange equipment, and on the other hand, it ensures the generation of electrical energy and heat at high temperatures of the heat source, when the use of high-temperature working fluids is limited their thermal stability (for example, the thermal stability of silaxanes is about 300 ºC). Calculations are performed for a heat source with temperatures of 250ºC and 350 ºC. The generated electrical power of the power plant at a heat source temperature of 350ºC is 460 kW. The generated thermal power by capacitors is 1755.3 kW. The mass of the capacitors of the second and third circuits is 5000 kg and 14500 kg, respectively. It is shown that when the temperature of the heat source decreases to 250ºC with a double-circuit design, the mass of the heat exchange equipment decreases. Thus, the mass of the condenser is 12700 kg, and the generated thermal power is 1430.2 kW. The values of the heat exchange surface area of a direct-flow steam generator with flue gases, and an intermediate steam generator between the stages of the thermal circuit of a regenerative heat exchanger, as well as a water-cooled condenser are given. When the condenser is cooled by atmospheric air, the surface area of the condenser increases significantly. A characteristic feature of organic working fluids is the low efficiency of heat exchange in heat exchangers, especially at low temperatures. The heat transfer coefficient in heat exchangers with organic working fluids is about 1500-2800 W/(m2•K), which causes an increase in the heat exchange surface area. In this case, it is necessary to reduce the diameters of pipes in the heat exchangers of the steam generator, to use the pipes with internal ribs, and coil pipes in order to reduce the pipe length. The use of steam generators with coil steam-generating channels, characterized by a higher heat exchange intensity, is promising. The selection of the optimal structure and parameters of the ORC installation is carried out taking into account the mutual influence of steam turbine units on the efficiency of working processes in general.

Technology has advanced quickly today. The parking lot is one location where technology is used. The world’s most technologically advanced parking lots can currently recognize a vehicle plate image, but it is believed that by using Internet of Things (IoT) technology that is connected with facial recognition photographs, it will be even better. The manual screening done by security agents is one of the parking issues. Naturally, this will take time, and the level of security is also poor because there is no verification when you enter. Only at the moment of exit are checks made, and the officer making the check is not always the same and does not have the vehicle owner’s memory. The adoption of this facial image recognition technology is expected to increase the parking system’s security. This service does not require training data. The proposed system makes use of real-time data, low-cost sensors, and user-friendly applications to enable users to track parking availability in real time. The aim is to streamline the parking search process by automating the identification of optimal parking spots, whether it be the ideal floor, location, or lot, thereby minimizing manual search time. The integration of low-cost sensors not only enhances cost-effectiveness but also reduces the ecological footprint associated with traditional parking systems and also promotes a more resilient and eco-friendly urban environment for the benefit of both users and lot owners.

In contemporary farming, efficient water management plays a crucial role in achieving optimal crop yields, endorsing water conservation, and upholding ecological balance. Current irrigation systems often lack precision, resulting in water wastage, suboptimal plant growth, and environmental degradation. This issue is pronounced evident in piped and micro irrigation networks, where manual control fails to adapt to fluctuating soil moisture conditions. This inconsistency in water distribution negatively affects agricultural yield and water conservation efforts. The core problem is the absence of an automated mechanism to regulate water release based on real-time soil moisture and centralised monitoring system. To tackle this, we’ve developed a real-time unified monitoring platform for automatic regulation of water release valves. Through the integration of soil moisture sensors, monitoring systems, and decision-making processes, our solution addresses the gap between water supply and crop demand, enhancing resource utilization and minimizing environmental impact. The amalgamation of instantaneous soil moisture information from various sensors into a centralized dashboard demands robust mechanisms for data collection, transmission, and processing. This real-time model, which unequivocally scrutinizes soil moisture data and associated parameters, significantly contributes to informed decisions concerning the timing and volume of water release.

Many areas in the Philippines are identified as potential ecotourism sites. For sustainable tourism development or site management, a carrying capacity analysis can ensure low and manageable environmental impacts, accommodate a high level of visitor satisfaction, and give stakeholders and local communities adequate economic returns. This study’s findings describe the carrying capacity of ecotourism attractions in Tablas Island, Romblon. It used a descriptive mixed method of research with 63 respondents selected using purposive and quota sampling techniques, and a GIS map was constructed to illustrate the physical geography and fundamental attributes needed to estimate the capability of the sites. The venues’ carrying capacity estimate was computed using Boullon’s Tourism Carrying Capacity Model. The results revealed respondents’ standard visitor requirements ranged from 1.43 m2 to 2.14 m2 to 2.86 m2. Most of them only required 1-2 hours but some needed as much as 4-5 hours to really enjoy their activities. The sites’ determined tourism carrying capacity is 1,157 visitors/day for Dubduban Falls in San Agustin; 612 visitors/day for Mablaran Falls in San Andres; and 138 visitors/day for Tuburan Falls in Odiongan. These results can be used to improve tourism site development in Tablas Island, Romblon.

Sensors and actuators play a vital role in realizing the Internet of Things (IoT) applications. The data transmission capability from edge devices to servers and vice-versa enables IoT applications to be more realistic and effective. However, one of the major challenges to IoT applications is power management at the edge devices. The power consumption of the edge devices depends on the amount of data transferred through the network in a defined interval. Data size and its applicability to the receiving device are controllable parameters, and consequently, energy efficiency can be improved. This work aims to establish an IoT architecture using a message queuing telemetry transport (MQTT) protocol that effectively handles the data transmission in the network. It also provides a solution for the elimination of data redundancy; hence, the network was effectively utilized, and the energy consumption was reduced in the edge devices. The proposed architecture was demonstrated with a potentiometer as a data generator and MQTT as a message broker. Further, the transmitted data was received at the edge devices and its performance was analyzed. Based on the results, it was verified that the client was able to receive the data without any loss in terms of precision. Data redundancy was avoided by disabling the data transmission whenever the nodeMCU identifies the constant sensor value. This retains the power at the edge devices and data transmission devices.

In the era of telemedicine, where remote treatment is gaining traction, the reliable transmission of biomedical signals is paramount. Turbo Coding has emerged as a pivotal method due to its robust performance and quality of service. However, the inherent complexity of Turbo decoders presents a significant hurdle. This paper investigates the efficacy of Soft Output Viterbi Algorithm (SOVA), Logarithmic MAP (Log-MAP), and Maximum A posteriori Probability (MAP) decoding techniques within Turbo decoding, crucial for real-time telemedicine applications. Focusing specifically on EEG signal transmission, we employ wireless channels and Turbo coding to enhance reliability. Viterbi decoding is leveraged to mitigate complexity, with an in-depth analysis of the SOVA algorithm’s Bit Error Rate performance across various parameters. This research enhances telemedicine by improving the reliability of biomedical signal transmission. Through efficient decoding techniques like Soft Output Viterbi Turbo Decoder, it ensures timely and accurate healthcare delivery. By reducing the need for patient travel and optimizing energy consumption, it aligns with Smart and Sustainable Energy Systems goals. This contributes to global healthcare accessibility and sustainability by minimizing carbon footprint and resource utilization. Ultimately, it promotes efficient, dependable, and eco-friendly healthcare solutions for all.

This study delves into the intricate typology of Perak’s cultural landscape through a comprehensive geographical mapping analysis. In Perak, the cultural landscape is experiencing changes, especially in the land and typology due to the overwhelming development. As cultural landscape plays a substantial role in historical and heritage values, efforts in documenting and analyzing the landscape change remain significant. This study documented a series of spatial data layers focusing on geographical context to describe and map the landscape typology in Perak. The geographical context including; agricultural landscape, coastal landscape, highland natural landscape, and lowland natural landscape was used as patches for the spatial and landscape-based metrics analysis. The analysis adopted the overlaying mapping technique by the Geographical Information System (GIS) in modifying and verifying the secondary data mapping by the Perak Structural Master Plan year 2040. The composite trajectory analysis in this study contributes to a more comprehensive cultural landscape typology toward sustaining cultural heritage value in the near future.

Colonial architecture is an architectural style derived from a mixture of European architecture that adapts to the local environment and climate, in this case the tropical climate of Indonesia. Therefore, colonial architecture is one of a good example of some traces of climate and environmental effects on built environment. Thus, this study wants to examine the environmental adaptations of colonial buildings in Aceh by taking examples from Banda Aceh. The city is amongst important cities during the Dutch colonial occupation. This research uses qualitative methods with observation, interview, and archival studies and documentation. This research aims to tie together the literature review of the historical narratives, climate adaptation, and cultural adoption of colonial architecture especially in Aceh and how it relates to wider Indonesia context. It uses some fieldwork data and analysis undertaken in Aceh. This study shows that raised-floor building and uses of timber are amongst obvious traces of environmental adaptations to Aceh. Through its historical developments, colonial architecture has adapted to tropical aspects. This highlights the importance of climate and environment in shaping colonial buildings and the ways in which colonial buildings adapts to local conditions to create functional and aesthetical spaces. Thus, further study can be undertaken to see how then cultural and environmental aspects influence the development of colonial architecture in contemporary uses and its conservation dilemma.
{"title":"Environmental Aspects and Historical Development of Colonial Architectural Heritage in Aceh","authors":"Cut Dewi, Izziah1, Lisa Maharani","doi":"10.1088/1755-1315/1361/1/012044","DOIUrl":"https://doi.org/10.1088/1755-1315/1361/1/012044","url":null,"abstract":"Colonial architecture is an architectural style derived from a mixture of European architecture that adapts to the local environment and climate, in this case the tropical climate of Indonesia. Therefore, colonial architecture is one of a good example of some traces of climate and environmental effects on built environment. Thus, this study wants to examine the environmental adaptations of colonial buildings in Aceh by taking examples from Banda Aceh. The city is amongst important cities during the Dutch colonial occupation. This research uses qualitative methods with observation, interview, and archival studies and documentation. This research aims to tie together the literature review of the historical narratives, climate adaptation, and cultural adoption of colonial architecture especially in Aceh and how it relates to wider Indonesia context. It uses some fieldwork data and analysis undertaken in Aceh. This study shows that raised-floor building and uses of timber are amongst obvious traces of environmental adaptations to Aceh. Through its historical developments, colonial architecture has adapted to tropical aspects. This highlights the importance of climate and environment in shaping colonial buildings and the ways in which colonial buildings adapts to local conditions to create functional and aesthetical spaces. Thus, further study can be undertaken to see how then cultural and environmental aspects influence the development of colonial architecture in contemporary uses and its conservation dilemma.","PeriodicalId":14556,"journal":{"name":"IOP Conference Series: Earth and Environmental Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141886777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Nowadays, complex steel-concrete composite structures are widely used, which combine the advantages and eliminate the disadvantages of similar metal and rein-forced concrete structures. With the help of the LIRALAND software complex (automated design system), which is effectively used in the scientific and practical field of the construction industry of Ukraine, the article presents the study of composite cross-sections taking into account the modern experience of foreign specialists. Numerical modelling with the help of the “Section Designer” software module of “LIRA-SAPR” makes it possible to reliably assess the performance of structural elements, taking into account changes in a significant number of studied parameters.
