Construction of a Responsive Web Service for Smooth Rendering of Large SSC Dataset: and the Corresponding Preprocessor for Source Data

This research focuses on a smooth rendering of continuous 2D map based on a smooth 3D vario-scale geographical data structure. A Space Scale Cube (SSC) offers non-redundant geometric data for the different level of details. SSC model represents geographic data as a closed polyhedron, to generate a 2D map; SSC is intersected with the projection...

Automatically Generating User-specific Recovery Procedures after Malware Infections

Malware poses a serious security risk in today’s digital environment. The defense against malware mainly relies on proactive detection. However, antivirus products often fail to detect new malware when the signature is not yet available. In the event of a malware infection, the common remediation strategy is reinstalling the system. However, the...

Spatial model-aided indoor tracking

In order to address the problem of indoor pedestrian tracking, this thesis reports a research on spatial models' ability to reduce tracking error of a WiFi positioning system. There are three main objectives in this research. First, it is to build a suitable spatial model for tracking. Second, it is to develop a tracking algorithm that can make...

A Local Time-Stepping Method for Multiphase Flow in Porous Media

Simulation of multiphase flow in natural subsurface formations include selection of time-step size, i.e., the discrete snapshots (steps) over which the time-dependent nonlinear process is investigated. The simulation results would naturally depend on the size of the discrete time step, according to the order of accuracy of the implemented...

Exploring Sustainability Considerations in Construction Project Manager Decision-Making In China: An Investigation Using The Q Methodology

This research examines how construction project managers in China integrate sustainability into their decision-making processes despite other constraints, such as cost, time, and quality. Using a Q-methodology, the study reveals a variety of managers' perspectives and strategies on sustainability, highlighting the complexity of integrating...

A Comprehensive Study of Dynamic SLAM: From Realistic Dynamic Environment Simulation Towards Robust Visual Localization

In recent years, visual Simultaneous Localization and Mapping (SLAM) have gained significant attention and found wide-ranging applications in diverse scenarios. Recent advances in computer vision and deep learning also enrich visual SLAM capabilities in scene understanding and large-scale operation. However, despite remarkable performance in...

A privacy-preserving tamper-evident revocation mechanism for verifiable credentials

Third-party verified credentials (e.g. passports, diplomas) are essential in our daily life. The usage of third-party verified credentials bring us convenience in authentication. The Verifiable Credential (VC) data model is a new standard proposed by the W3C association to ease the expression and verification of third-party verified credentials...

Design for Togetherness at Home: Integrating Technology to Bond Children and Grandparents Through Shared Experiences

Strong intergenerational relationships can provide emotional support and stability for both grandparents and grandchildren. Technology tools have been proven to be beneficial in connecting grandchildren and grandparents. Prior work mainly examined how to use technology to connect children and their grandparents over a distance. Those collocated...

Towards a transition territory: Planning and design strategies to improve social and ecological conditions in the peri-urban area of Shanghai

Shanghai has experienced rapid urbanization over the past 30 years, with a large number of rural areas being transformed into semi-urbanized areas with mixed functions. The main drivers were top-down state-led development, market forces, and bottom-up rural industrialization. The scale and speed of this process have far exceeded expectations,...
