The Comparative Study

This paper presents the exploitation of Wi-Fi signals sensors using fingerprinting method to capture the location and provide the possible navigation paths. Such approach is practical because current smartphones nowadays are equipped with inertial sensors that can capture the Wi-Fi signals from the Wi-Fi’s access points inside the building. From the comparative study conducted, the AnyPlace development tool is used for the development of dynamic navigation indoor map. Its components, namely; Architect, Viewer, Navigator and Logger are used for different specific functions. As a case study, we implement the proposed approach to guide user for navigation in Sunway Pyramid Shopping Mall, Malaysia as floor plan as well as using Google Maps as the base map for prove of concept. From the developer point of view, it is observed that the proposed approach is viable to create a dynamic navigation indoor map provided that the floor plans must be generated first. Such plan should be integrated with the SDK tool to work with the navigation APIs. It is hoped that the proposed work can be extended for more complex indoor map for better implementation.

PurposeThis paper aims to describe and demonstrate a quantitative areal openness model (AOM) for measuring the openness of floor plans. Creation of the model was motivated by the widely reported but rarely quantified link between openness and adaptability.Design/methodology/approachThe model calculates values for three indicators: openness score (OS), weighted OS (WOS) and openness potential (OP). OS measures the absence of obstructions (walls, chases, columns) that separate areas in a floor plan. WOS measures the number of obstructions while also accounting for the difficulty of removing them. OP measures the potential of a floor plan to become more open. Indicators were calculated for three demolished case study buildings and for three adapted buildings. The case study buildings were selected because openness – or lack thereof – contributed to the owners' decisions to demolish or adapt.FindingsOpenness indicators were consistent with the real-world outcomes (adaptation or demolition) of the case study buildings. This encouraging result suggests that the proposed model is a reasonable approach for comparing the openness of floor plans and evaluating them for possible adaptation or demolition.Originality/valueThe AOM is presented as a tool for facility managers to evaluate inventories of existing buildings, designers to compare alternative plan layouts and researchers to measure openness of case studies. It is intended to be sufficiently complex as to produce meaningful results, relatively simple to apply and readily modifiable to suit different situations. The model is the first to calculate floor plan openness within the context of adaptability.

Abstract- There are allegations that elements of Javanese temples are also can be found at The Angkorian temples because the Java Middle Classic temples are older than Angkorian temples and Jayawarman II lived in Java at that time. This can be proved by a comparative process between the architecture elements: mass, plans, figures and ornaments owned by the temples that represents its era in both kingdom. Angkor Wat is a synthesis of the development in Angkor culture that reach its the peak of glory. Angkor Wat has architectural elements of Java Middle Classic temples, especially Prambanan and Borobudur. This led to the alleged of similarity from architectural elements between the temples in the two kingdoms. This Study approached by quantitative with semi qualitative method. Through the study on the main temple buildings of the Java Middle Classic and the main temples of the Angkor Wat era with purposive sampling in relation of mass, plan, figure, and ornament. Described descriptively.Angkor Wat is generally inspired by Borobudur-Prambanan. Broadly speaking, it shows the similarity of Prambanan-Borobudur architectural elements to Angkor Wat. Angkor Wat is a synthesis of combining the elements (eclecticism) of Borobudur-Prambanan, but Prambanan has stronger element (indoor temple, tower temple, Hindu temple). In principle (mass, plan, and figure) shows the incorporation of Borobudur-Prambanan, but by ornament on its processing indicates there is further development (dominated findings exist but not similar). Key Words: tipo-morphology, comparison, Angkor, Indochina, Java

Abstract Many floor plans are proposed during the early stage of an apartment housing remodeling project as it involves a multitude of entities with different stakes. Consequently, the process to converge the opinions per the individual's preference on an agreed remodeling floor plan becomes repetitive and time consuming. For these reasons, structural evaluation of each proposed conceptual plan is often bypassed and postponed until a finalized floor plan is determined. An automated structural evaluation application for architectural floor plans of apartment housing with the load-bearing wall system is developed on this necessity. The application reads the conceptual drawings and returns various supportive information regarding structural performance, almost instantly. The outputs from the application include the amount of removed, remaining, and new bearing walls, 3D views of each wall component overlaid on the floor plans and their dimensions, area moment of inertia (AMOI) of the walls, torsional resistance of the floor plans, and other supportive indices. For easy and intuitive communication with the users, an abstract and simple quantitative value, structural index (SI), is suggested and included as one of the outputs in the application. In order to validate the developed automated application, a case study is conducted with an ongoing remodeling project, and the results, accuracy, and processing time are compared with the conventional hand calculation method. The application is accurate with errors of less than 1.3%, while the processing speed is nearly seven times faster. With the developed application, the designers could evaluate their conceptual drawings in almost real time. In addition, the stakeholders would communicate in a more straightforward language with the outputs of the application, such as the AMOI evaluation and SI results. Consequently, it is anticipated that the decision-making process during the early stage of a remodeling project would be expedited with the help of the developed automated application.

Abstract. The historical center of São Luís is host to a diverse historic and urban ensemble, reminiscent of the 18th and 19th centuries. The architectural typology which can be found there illustrates the strong influence drawn from the Portuguese style known as Pombalino, developed during the reconstruction process of Lisbon after the 1755 earthquake. Due to the historical relevance of these buildings which encapsulate this period in time, it is important to preserve and maintain the buildings located in this region. Adaptive reuse projects have an important role to play in preserving architectural ensembles like this. The first part of the adaptive process is to document and understand the original configuration of the building with the aim of maintaining the elements with historical relevance. Therefore, this project proposes the use of a shape grammar approach to analyze floor plans, aiming to further contribute to adaptive reuse projects for ‘Sobrado’ buildings. The process focuses specifically on a case study building and aims to document and identify the specific placement of elements in the floor plan in an effort to provide a deeper understanding of future adaptive reuse.

Lacking indoor navigation graph has become a bottleneck in indoor applications and services. This paper presents a novel automated indoor navigation graph reconstruction approach from large-scale low-frequency indoor trajectories without any other data sources. The proposed approach includes three steps: trajectory simplification, 2D floor plan extraction and 3D navigation graph construction. First, we propose a ST-Join-Clustering algorithm to identify and simplify redundant stay points embedded in the indoor trajectories. Second, an indoor trajectory bitmap construction based on a self-adaptive Gaussian filter is developed, and we then propose a new improved thinning algorithm to extract 2D indoor floor plans. Finally, we present an improved CFSFDP algorithm with time constraints to identify the 3D topological connection points between two different floors. To illustrate the applicability of the proposed approach, we conducted a real-world case study using an indoor trajectory dataset of over 4000 indoor trajectories and 5 million location points. The case study results showed that the proposed approach improves the navigation network accuracy by 1.83% and the topological accuracy by 13.7% compared to the classical kernel density estimation approach.
