Rajendran, L. (author)
This thesis presents an incremental ?? capacitance-to-digital converter (CDC) that serves as an interface circuit for a MEMS-based pressure sensor. The thesis presents a systematic analysis of the CDC and compares different CDC architectures. A novel non-linear CDC is also proposed and analysed. Energy-efficiency of the CDC is improved by...

In current architectural practice some important changes are taking place because of the development of numerous Building Performance Simulations (BPS) tools to support design decisions during early phases of the design process. Many difficulties still persist, however, not necessarily due to the limitations of the available technology, but to...

This thesis discusses the theory, architecture design, circuit design and measurements of an ultra-low-energy reconfigurable interface circuit for resonant gas sensors. This interface circuit employs a transient measurement method. The resonant sensor is driven at a frequency close to its resonance frequency by an excitation source that is...

Sensing in smartphones consumes a significant amount of energy and leads to quick depletion of the battery. Most of the existing solutions to overcome the short battery lifetime caused by periodic sensing are personalized. They tend to learn and predict the user activities. Thus, fewer samples are required to recognize user state and sensing...

This graduation project focused on the scooter. Scooters offer cheap, flexible and reliable transport. However, their emissions are quite high. This leads to the problem description for this project: energy efficiency in current scooters is not as high as it can be. A lot of improvement can be gained in the vehicles efficiency by regenerating...

Although the use of DC in power systems was discarded years ago due to its inefficiency and non-economic feasibility, in the last decade the technological advance of power electronics has enabled DC to make its way back to the power system. This paper investigates the use of DC for electricity distribution at voltage levels below 1500V. A...

Commissioned by the Dutch Railways Operation (NS Reizigers) research has been conducted on the possibilities to better incorporate energy-efficient train operation into the timetable. The motivation for this research is based on the fact that energy-efficient operation is not yet optimally included in the timetable design. This is because of the...

Energy efficiency and architectural value of post-war residential buildings in Europeis poor. To deal with energy efficiency, decay and livability problems, improvements of building façades seem to be indicated especially when combined with tenants’ preferences for architectural aesthetics. But a valid way to assess multiple characteristics of...

Despite continuous developments in the field of MBR technology, membrane fouling together with the associated energy demand and related costs issues remain major challenges. The efficiency of the filtration process in an MBR is governed by the activated sludge filterability, which is still limitedly understood and is determined by the...

Europe expects the housing sector to evolve towards ‘nearly zero-energy’ dwellings. Meanwhile, general terms and research, marketing and legal definitions considering such dwellings have already been introduced. Appraisal of existing definitions is now needed for further policy development. This paper examines what nearly zero-energy terms can...

This paper describes an energy-efficient CMOS temperature sensor intended for use in RFID tags. The sensor achieves an inaccuracy of ±0.15°C (3σ) over the military temperature range (-55 to 125°C) and dissipates only 27nJ/conversion: over 20× less than a previous sensor with comparable accuracy and resolution [2]. This energy efficiency is...

Since 2008 new long-term agreements on energy-efficiency have become effective in the Netherlands. Participating organisations of thirty-six sectors have agreed with the Dutch government to make efforts to realise energy-efficiency of 30 percent in the period 2005-2020 and 50 percent - as a guideline - before 2030. Higher education is...
