Urban growth dynamics have resulted an increase in population and rapid conversion of green open space (GOS) into built-up areas. Despite the minimum standard provision has been stated 30% on spatial regulation Law No 26/2007, Bekasi City Government has been struggling to preserve their remaining valuable green open spaces. This paper aims to propose a concept emphasizing the provision of green open space using green infrastructure by the linkages between green open spaces in the form of areas (hubs) which connected by a corridor (links). Built upon theoretical bases of the benefits of green open space that cannot be limited by administrative boundaries, the study uses Bekasi City and Bekasi Regency at the regional scale as a study case. This study calculated the potential area of green infrastructure and compared ecosystem services produced before and after the application of the concept. The result showed that the application of the Green Infrastructure concept has significantly increased the quantity (area) as well as the quality (ecological function) of green open space. An interconnected green open space was also able to enhance the ecosystem services by absorbing carbon dioxide. All of these potential benefits have implications on the Green Infrastructure development strategy to establish a more sustainable city.

Argapura is one of the village areas in Cigudeg Subdistrict which has potential unique characteristics for a tourist destination, namely Geopark. Argapura Village is one of the Pongkor National Geopark development villages covering 15 sub-districts in Bogor Regency. Pongkor National Geopark is a unitary space with geodiversity, culturediversity and biodiversity which aims to preserve and protect the wealth of natural resources. The geopark is located very close to tourism activities, but the existing tour has not specifically touched the educational aspect (educational tourism). Educational tourism is a tourism packaging program that is loaded with educational values in each of its activities. Argapura Village needs to be developed educational tourism aimed at all visitors. The objectives of this study were to identify and analyze the potential of educational tourism objects in Argapura Village, and to arrange educational tourism program in Argapura Village. Data collection through literature studies, field surveys and interviews with stakeholders. Data analysis using tables and described based on the criteria of educational values and geopark elements. The results of study showed that Argapura Village has two main potential attractions/educational tourism objects, namely Angklung Gubrag and Gudawang Caves.

There is a great deal of emphasis currently in the Navy on the issues of reliability and maintainability. If a system or component is out of commission, it obviously cannot perform its mission. Thus, systems and components must be reliable, with low failure rates, and maintainable, with short repair times when the system does become inoperable. To be effective, these attributes must be incorporated into new ship systems early in the design stage. The Rankine cycle energy recovery (RACER) system is a heat recovery steam cycle designed to recover energy from the exhaust of an LM2500 gas turbine for augmentation of a ship's propulsion system. The RACER system provides several advantages to a gas turbine powered ship, one of which is improved fuel efficiency for significant annual fuel savings. This saving does not come free, however, since, in general, any additional system installed in the ship will have some maintenance requirements. In keeping with the Navy's current emphasis, a key philosophy in the design of the RACER system has been to minimize this maintenance burden. After a brief description of the RACER system and its design philosophy, the techniques being used during the design phase to minimize the maintenance burden on the fleet are presented. Trade-off studies concerning acquisition versus life-cycle costs, including fuel and maintenance costs, are discussed. Innovations incorporated into this state-of-the-art system are reviewed with an emphasis on design for affordability.

A comparison study between the transport equation model and diffusion equation model for room‐acoustic predictions in long spaces.

引用

The Journal of the Acoustical Society of America 2009年第4_SUPPLEMENT期126卷 2288-2288页

This paper compares two numerical models: diffusion equation model and transport equation model, for room‐acoustic predications in long spaces. Mathematically, the diffusion equation is the asymptotic approximation to the transport equation, therefore is expected to be less accurate. In addition, the transport equation intrinsically includes the direct sound field while the diffusion equation does not. However, due to its simple form of the diffusion equation, it has certain computational advantages over the transport equation model, e.g., it is less computationally expensive. When comparing the two models with the ray‐tracing based method, the transport equation is shown to be more precise, especially when the walls are highly absorptive. Nevertheless, the diffusion equation model performs fairly well provided that the absorption on the walls is low. In this case, the diffusion equation model might be preferred over the transport equation model due to a low computational load.

Urbanization and climate change increase heat stress and health risks in cities, necessitating effective response strategies. Traditional research has focused on thermal sensation in specific locales, overlooking the broad impacts of urban environments and the importance of regional and citizen input in crafting mitigation approaches. This study examines the effects of heat waves in Suwon City, analyzing thermal perception among residents across different urban spaces using citizen science. Data on temperature and subjective heat sensations were collected through homemade sensors over three years. The analysis investigated thermal sensation differences across spatial types— open high rise, open low rise, compact mid-rise, urban park, and lake park—utilizing boxplots, and examined thermal perception variations by age using the R program localized smoothing methodology. The results revealed significant differences in thermal sensation, especially above 32°C, with the highest discomfort reported in lake park areas and the lowest in open high-rise and low-rise zones. An age-related trend showed increased heat sensitivity among the 19–30 age group, decreasing in older participants. These findings underscore the limitations of one-size-fits-all heatwave responses and advocate for customized strategies informed by local conditions and resident experiences, highlighting the value of a bottom-up approach through citizen science. © 2024, The Authors.

The impacts of alternative patterns of urbanization on greenhouse gas emissions in an agricultural county

Different patterns of urban development may have widely varying long-term effects on greenhouse gas (GHG) emissions. To investigate such effects, we used UPlan geographic information system-based software to model three 2050 urban-growth scenarios for Yolo County, a predominantly agricultural area near Sacramento, California. Two scenarios correspond to the Intergovernmental Panel on Climate Change's A2 and B1 storylines. We also added a third, infill-only scenario called AB32-Plus that assumes continued strong climate change policy in California and highly compact urban development. Results show dramatically different levels of GHG emissions from transportation and residential-building energy use in the three scenarios, especially when compact urban development is combined with strong assumptions about energy efficiency and population. The preservation of farmland is also an important climate mitigation and adaptation benefit of the compact-development alternative. © 2013 © 2013 Taylor & Francis.

The diverse urban morphology leads to different microclimates in urban areas. However, little is known about the relationship between different types of urban morphology in humid subtropical climate during extreme heat. Therefore, we selected six types of streets with three building heights and two street orientations in the Nanjing, China, and examined how they impact differently on thermal environment under extreme heat. Our results showed that: (1) the cooling effects of street orientation in NE-SW (Northeast to Southwest) was more effective than the street orientation in N-S (North to South) (3) Physiological Equivalent Temperature (PET) in the "Very hot"(PET above 41°C) level was consistently lower on N-S street orientation compared to NE-SW street orientation throughout the day, with the difference decreasing as building height increased. (4) The worst thermal comfort was indicated in the NE-SW street orientation with Low-rise buildings, where the proportion of "Very hot" level in 63%. Conversely, the lowest proportion is 42.7% for Middle-rise buildings on the N-S street orientation, indicating the best thermal comfort in this study. Our findings provide new insights for urban planners and policymakers in promoting healthy cities and environmentally friendly cities through rational urban morphology planning. © 2023, The Authors.

Measuring the uniform diffusion coefficient: Synthesized aperture goniometer measurements

引用

Proceedings of Meetings on Acoustics 2009年第1期6卷

作者： Philip Robinson Ning Xiang Peter D.Antonio Graduate Program in Architectural Acoustics Rensselaer Polytechnic Institute Troy NY 12180 Graduate Program in Architectural Acoustics School of Architecture Rensselaer Polytechnic Institute 110 8th St. Troy NY 12180-3590 RPG Diffusor Systems Inc.

There are currently two methods to measure the diffusion / scattering from acoustical surfaces: reverberation chamber measurement and in-situ measurement using a semicircular array of microphones called a goniometer. Each of these methods has advantages and drawbacks. The reverberation chamber method accounts for random incidence, but produces inconsistent results for materials of the same profile but different absorption. It does not distinguish between one-dimensional and two-dimensional surface topologies, since the sample is rotated, and is also inapplicable to high absorption materials. The goniometer measurement quantifies directivity as well as diffusion, but presents challenges related to processing power, as many microphones are required to achieve reasonable resolution. Using a procedure akin to synthesized aperture radar, a 2.5 deg. resolution polar plot of the 180 deg. response is achieved by scanning eight microphones rather than employing a full array of 72. Also, since the direct sound and reflected sound arrive at the receiver in close succession when measuring low incident angles, special processing must be exercised in order to resolve the relationship between the sounds. This research addresses the challenges of the goniometer measurement and attempts to use a synthesized aperture goniometer to derive accurate diffusion and directivity properties of materials.
