Subgraph Matching via Fused Gromov-Wasserstein Distance

Subgraph matching is a fundamental problem in various fields such as machine learning, computer vision, image processing, and bioinformatics, where detecting specific substructures within an object is often crucial. In these domains, not only structure plays an essential role, but also the feature information on nodes should be incorporated,...

Dead Time Control Circuit in Monolithic GaN Class D Audio Amplifier

GaN transistors have advantages over conventional Si MOSFETs, such as lower on-resistance, lower parasitic capacitance, higher break-down voltage, etc. However, due to the lack of the body diode, when GaN transistors conduct reverse current during dead time, the source-drain voltage (VSD) can be very large (up to 4-5 V, depending on the output...

The Impact of ventilation systems on controlling the Spread of Covid-19

The closure of educational institutions during the COVID-19 pandemic had significant negative impacts, emphasizing the need to keep schools open while ensuring safety. It is crucial to find ways to keep educational institutions open while ensuring the safety of students and staff. While measures such as mask-wearing and social distancing have...

HRM practices and international technology transfers (ITT) in the M&A context: A case study of the ITT between a Chinese medical enterprise and a Dutch company

In the business world, international mergers and acquisitions (M&A) are often adopted. To localize technology afterward, international technology transfers (ITTs) are often carried out. Human Resource Management (HRM) practices can help the technology transfer process achieve better performance. However, human resource interactions within...

The study of corrosion on carbon steel and zinc under thin-film electrolyte

Atmospheric corrosion is one of the most widespread types of metal corrosion in the world. Commonly, atmospheric corrosion is affected by the electrochemical properties of the metal and environmental factors, such as humidity, temperature and the properties of the electrolyte on the metal surface. Currently, there still lack of laboratory...

Progression of Aggregate Loss on Porous Asphalt

Porous asphalt resides on most top layers of Dutch roads. Scheduling maintenance for these roads is generally dependent on several factors, but ravelling, the loss of aggregates in the top layers, is the main reason for maintenance on Dutch roads. With the recent framework of the DOS-LCMS scheme generating values for aggregate loss in...

Microstructure Development and Different Heat Treatment of Nickel Aluminium Bronze in Wire and Arc Additive Manufacturing Process

Wire and Arc Additive Manufacturing (WAAM) is a promising rapid prototyping process, which can potentially replace the traditional subtraction methods with the benefits of materials, cost and time savings and environment friendliness. It is mainly used to fabricating complex 3-Dimensional large-scale components. This thesis explores the welding...

A High-Resolution Energy-Efficient Resistor-Based Temperature Sensor

High-resolution energy-efficient temperature sensors are often used for the temperature compensation of frequency references, and of a wide variety of other sensors. Of the various types of CMOS-compatible temperature sensors, those based on resistors are, at least in principle, the most energy efficient. The challenge is then how to design...

Education: Bridging the gap

This Program is a vocational school which is built on the national border of USA and Mexico to provide high quality education to students from both countries, helping to solve the problem of Mexico commuter students, and also supply infrastructure to Mexico community. The design process start with date collection, site research, interview and...

Effects of Li4Ti5O12 coating on the performance of LiNi0.5Mn1.5O4 cathode in Li-ion batteries

Lithium ion batteries have attracted a lot of attentions due to the high power density and specific density that can potentially meet the requirements of new applications in the future. In recent years, one of the most promising cathode layer applied in lithium-ion batteries is called spinel LiNi0.5Mn1.5O4 (LNMO), which has advantages of high...

Optimization on Burst Allocation in D2DWRAN

With rapid development of digital devices with wireless services, communication networks play a significant role in our daily lives. The explosive data demand makes it urgent to extend the capacity of the existing networks. Cognitive Radio (CR), which can sense and use the frequency band dynamically, can provide an efficient radio frequency...

Offline Power Allocation and Spectrum Sensing Strategy in Energy-Harvesting Cognitive Radio Networks

Energy-harvesting cognitive radio network has emerged as a solution to increase energy and spectrum efficiency. In this thesis, we propose short-term offline optimal power allocation algorithms for multi-user energy-harvesting cognitive radio networks considering interference between secondary users. Assuming finite and rechargeable batteries...
