A Compact Temperature-Stable RC Frequency Reference

This paper presents a 0.01mm2 10MHz FLL-based RC frequency reference that does not require the use of resistors with complementary temperature coefficients (TCs), thus facilitating its implementation in a wide range of standard CMOS processes. Fabricated in a 0.18μm CMOS process, it achieves a frequency inaccuracy of ±0.28% from −45°C to 125°C...

Decentralized Conflict Resolution for Autonomous Vehicles

This work presents a decentralized optimization conflict resolution method based on a novel Alternating Directions Method of Multipliers (ADMM) variant and model predictive control (MPC). The variant, titled Online Adaptive Alternating Direction Method of Multipliers (OA-ADMM) aims to unify the application of ADMM to online systems, i.e. systems...

Framework for Determining Impacts of Malfunctioning of DTM Systems on Traffic Flow: Development and A Case Study for the Amsterdam Region

Dynamic traffic management (DTM) plays an important role from Dutch policy perspective to prevent road congestion and has been developed from control strategies to services. Five traffic control centers, 22 different DTM systems with 35 functions and over 50,000 DTM components make up the national traffic management network in the Netherlands....

Redesign Frequency for Fixed-time and Vehicle-actuated Signal Controllers at A Right-turning Channelized Intersection

Fixed-time control and vehicle-actuated control are two main signaling strategies implemented at intersections for urban traffic management. The timing and structure of the controllers are usually designed optimally based on average historical demand patterns at the intersection. Under the premise of performance quality assurance, both fixed...

Transverse 3D Electrical Properties Tomography

MR-based Electrical Properties Tomography (EPT) is a medical imaging modality to reconstruct the electrical conductivity and permittivity inside the human body based on the magnetic field data obtained from an MRI system. Currently, 2D CSI-EPT implementation is able to generate reliable reconstructions under special assumption of electromagnetic...

Visibility in Physical Internet Port: Use-Case Driven Conceptual Design of Information Flows to Track and Trace Modular Containers in Terminal Operating System in PI-Port

This research has proposed a tentative design of information flows on PI embed three PI components: (1) modular containers, (2) open interface web, and (3) global protocols. Through the design, this research has identified potentials of the primary PI elements to resolve current issues in freight logistics (i.e., inefficient space utilization on...

Density Adaptive Sleep Scheduling in Wireless Sensor Networks

Broadcasting by flooding is one of the most fundamental services for both wired and wireless networks. This also includes several sensor network applications that use broadcasting to spread information from one sensor node to the other sensor nodes in the entire sensor network. These wireless sensor networks have certain characteristics such as...

Enhanced natural ventilation method for atrium space

This paper is written for the TIDO-course AR0532 Smart & Bioclimatic Design Theory. Energy saving is a relevant issue nowadays. Heating, ventilation and air conditioning (HVAC) occupies the largest portion both in residential and non-residential field. This consumption goes with the demand for thermal comfort of occupants. It is a prevalent way...
