Within an intelligent automated cyber-physical system, the realization of the autonomous mechanism for data collection, data integration, and data analysis plays a critical role in the design, development, operation, and maintenance of such a system. This construct is particularly vital for fault-tolerant route-finding systems that rely on the imprecise GPS location of the vehicles to properly operate, timely plan, and continuously produce informative feedback to the user. More essentially, the integration of digital twins with cyber-physical route-finding systems has been overlooked in intelligent transportation services with the capacity to construct the network routes solely from the locations of the operating vehicles. To address this limitation, the present study proposes a conceptual architecture that employs digital twin to autonomously maintain, update, and manage intelligent transportation systems. This virtual management simulation can improve the accuracy of time-of-arrival prediction based on auto-generated routes on which the vehicle's real-time location is mapped. To that end, first, an intelligent transportation system was developed based on two primary mechanisms: 1) an automated route finding process in which predictive data-driven models (i.e., regularized least-squares regression) can elicit the geometry and direction of the routes of the transportation network from the cloud of geotagged data points of the operating vehicles and 2) an intelligent mapping process capable of accurately locating the vehicles on the map whereby their arrival times to any point on the route can be estimated. Afterward, the digital representations of the physical entities (i.e., vehicles and routes) were simulated based on the auto-generated routes and the vehicles' locations in near-real-time. Finally, the feasibility and usability of the presented conceptual framework were evaluated through the comparison between the primary characteristics of the physical entities with their digital representations. The proposed architecture can be used by the vehicle-tracking applications dependent on geotagged data for digital mapping and location tracking of vehicles under a systematic comparison and simulation cyber-physical system.

An end-of-life strategy is concerned with how to disassemble a product and what to do with each of the resultingdisassembled parts. A sound understanding of the end-of-life strategy at the early design stage could improve theease of disassembly and recycling in an efficient and effective manner. Therefore, the end-of-life decisionmaking for environmental conscious design has become a great concern to product manufacturers.We introduce a novel concept ofeco-architecture which represents a scheme by which the physical componentsare allocated to end-of-life modules. An end-of-life module is a physical chunk of connected components or afeasible subassembly which can be simultaneously processed by the same end-of-life option without furtherdisassembly. In this paper, a method for analyzing the eco-architecture of a product at the configuration designstage is proposed. It produces an optimal eco-architecture under the given environmental regulations. To dealwith the case ofa complex product, the method is extended for analyzing hierarchical eco-architecture.

Physical housing environments of the rural area including houses and its connected facilities have much changed for decades. Such changes had an effect on the landscape of the rural area to much extent. As houses were renovated or rebuilt in rural area, the landscape were also remade. It could be expected that these changes of the physical housing environments are related with both urban developments and demands of the rural area itself. Thus, some rural areas in Gyeonggi province as the most related cases with urban area were chosen for a case study. On the methodology of the landscape assessment, the landscape factors related with housing environments were reviewed and some connected queistions were also interviewed. Landscape Assessment should include various social and cultural aspects, but in this thesis the visible factors are integrated. So considering many support policy oriented for physical investment and improving in rural areas, landscape assessment and interpretation are very helpful and meaningful.

Scientific methods that measure the physical demand requirements of a construction operation have not been arrived at maturity in construction community. It is attributed to the difficulty involved in performing controlled experiments on the operation and its' volatile jobsite environment. This paper presents a method that measures the physical demand requirement of the waterproofing activity and verifies the differences between various operations (e.g., a primer painting and a polyurethane coating) consisting of the activity. Two hypotheses, which are involved in the operations, are summarized as follows: [Hypothesis 1] when one performs the same amount of work; the one's average heart rate required for the polyurethane coating operation is higher than that required for the primer painting operation. [Hypothesis 2] when one performs the same amount of work, the one's break time required for the polyurethane coating operation is longer than that required for the primer painting operation.

The development of modern industry and the production of new materials of architecture have recognized as an important aspect. This study intended to discuss about the meaning of main elements of the architecture materials, its implications for properties, and, highlighted meaning of the properties of modern interior design. The purpose of this study is to analyze the case studies of Place and Physical materials of synaesthesia of modern architecture as well as modern architecture is not only concentrated in the visual aspect but also the larger ramifications of sensory. Synesthesia in architectural space can be called experiential existence that built in the space of human perception and based on the human emotion that targeted by physical architectural space. Accordingly, these case studies are to consider about how the materials being passed by any effect in a modern interior space presented, In order to find the essential meaning in modern interior space, this studies focused on Swiss architect Peter Zumthor's cases. Following analyze of Peter Zumthor's place of architectural space and materials, this study structured by the six kinds of synesthesia characters. First, time and remember to infer changes, Second, traditional and regional ingredients involve the substitution of one empirical space, Third, non-materiality through the neutralization, Fourth, auditory memory through the embodiment of everydayness, Fifth, trail through the sense of smell for the presence, Sixth, the relationship of natural and industrial products. Peter Zumthor's characteristics of these works are result of factors on the synesthetic relationship with the human response to architecture, the five senses, memories, experiences, and temperature. Also it is a synesthetic result of all human emotion to clarify of the architecture materials and non-material mediums by which light by a compound.

This paper attempts to improve the existing architecture of location register for location management in Private Network to Network Interface(PNNI)-based wireless ATM networks. Our approach enhances the hierarchical architecture of location registers based on a PNNI hierarchical architecture, which is referred to as the logical hierarchy architecture of location registers. This paper introduces a logical hierarchy architecture for location registers to reduce the cost of their location management. This logical hierarchy architecture of location registers begins with the lowest level physical location registers that are organized into clusters called logical groups. These logical groups are then represented in higher layers by logical nodes. These logical nodes are again grouped into clusters that are treated as single nodes by the next higher layer. In this way, all location registers are included in this tree-type logical hierarchy architecture. Compared with the existing physical hierarchy architecture of location registers, the analysis results show that the proposed logical hierarchy architecture can reduce the number of databases and thereby the average total location management cost.
