The importance of moisture feedback between continental precipitation and evaporation, referred to as moisture recycling, is still under debate. Most of the research in the past focused on the contribution of recycling to precipitation within a certain region only. This paper clearly distinguishes between different definitions of moisture...

This report concerns the development of a jacket for people with balance problems. Patients with failing balance organs can have serious difficulty to maintain their balance. The balance jacket contains a sensor and a belt of actuators. The sensor determines the orientation of the patient and provised feedback to the jacket. The jacket contains...

The efficient use of the power budget in mobiles and small satellite applications is of primary importance because of the reduced size of the power sources. The limited power supply has to be spent wisely. In a transmitter, the power amplifier is the main consumer of that budget, which is why it has to be as efficient as possible. Unfortunately,...

Currently, a low cost, single-chip multi-band WCDMA/GSM transceiver is needed for the 3G segment of the cellular communication that provides backward compatibility with the 2G GSM network. In this thesis, a novel, multi-band, low noise transconductance amplifier (LNTA) is presented. The LNTA has three stages, which are the transconductance,...

In teleoperations, haptic feedback allows the human operator to touch the remote environment. Yet it is only partially understood to what extent the quality of haptic feedback contributes to human-in-the-loop task performance. This paper presents a human factors experiment in which telemanipulated task performance is assessed for three stages of...

High rejection rates indicate that prosthetic users are not satisfied with the performance of their arm prostheses. In theory, one of the advantages of shoulder controlled prosthesis, compared to myo-electric prostheses, is that the user gets direct proprioceptive feedback about opening width and pinch force of his prosthetic hand. However,...

Worldwide, consumers demand companies to take more responsibility for what environmental problems their products might cause. Companies are following this demand from consumers by producing more sustainable products. HP forms no exception and has implemented so called “Eco solutions” to reduce the environmental impact of their consumer inkjet...

This report describes the design process of a training system for track sprinters that gives feedback about the sprint technique in order to make improvements. The graduation project is focused on the interaction for effective feedback (what, how and when) between the system and the athlete and coach. According to the literature research the...

Epidural anesthesia is a commonly used anesthesia method during surgery or giving birth to a child. During the insertion of the needle in the back of the patient, the anesthetist has to interpret the different forces which requires extensive skills. To obtain these skills the residents train on patients, which is not without risk. Due to a lot...

Traditional Electronic Stability Control (ESC) systems influence planar vehicle motions to better match these to the driver’s intention. These systems use the Anti-lock Braking System (ABS) hardware to generate the needed tire forces. This has a large impact on longitudinal vehicle motions. A second method of altering the front wheel tire forces...

Speed skaters often mention a so called “good feeling”, this “good feeling” is the feeling as if the skating goes automatically. Most of the time this feeling rises when skating behind a better skater, but sometimes it also happens when skating alone. This is the feeling nearly every speed skater is after when skating then they say something...

Transactional Memory is a parallel programming paradigm in which tasks are executed, in forms of transactions, concurrently by different resources in a system and resolve conflicts between them at run-time. Conflicts, caused by data dependencies, result in aborts and restarts of transactions, thus, degrading the performance of the system. In...

During this project, a mobile haptic feedback device, aimed at virtal object representation in virtual reality was developed. The device is capable of providing its users with passive force feedback between their thumb and index finger. The device consists of a magnetorheological fluid damper, suspended between the thumb and the index finger by...

Accurate positioning of the needle tip during insertion is essential to ensure a maximum effect of the treatment. Target error is a problem and a lot research fields aim to improve needle insertions. The possibility to measure cutting force and stiffness force separately from friction forces supports the development of new types of needles,...

A guideline on how to design and specify a Decision Feedback Equalizer (DFE) for bitrates of 10 Gbps and Beyond. First, this work provides a classification of the state of the art for Decision Feedback Equalizers. Second, this work provides insight about the behaviour of a DFE with increasing number of taps and channel length with measurements...

The Master’s programme Industrial Ecology is jointly organised by Leiden University and Delft University of Technology. Sustainable development is a young, developing field in which many standards, certificates, and initiatives are spawning. Companies are expected to work on sustainable development by its customers, investors, and society in...

The better understanding of neuromuscular control of the human neck is of critical importance to understand whiplash injury and neurological movement disorders. Isometric experiments using electromyography (EMG) are an appropriate method to study neuromuscular control patterns of neck muscles. As the human head-neck system is highly complex, it...

This master thesis describes the dynamical behaviour of a loudspeaker woofer and the modelling of it. By the use of the knowledge gained from the model, a feedback controller is implemented in order to enhance the woofer’s performance in terms of acoustic total harmonic distortion (THD) and low frequency bandwidth. The first objective of the...

Abstract – Background: A principal design choice in providing steering wheel force feedback to assist drivers during lane-keeping is whether feedback should be provided for any error with respect to the lane centre (continuous feedback) or only when acceptable tolerance limits are exceeded (bandwidth feedback). Problem: Research has shown that...
