Abstract:

An educational framework proposed by Chi (2009) aims to link overt study activities with outcomes via the underlying cognitive processes experienced by learners. Activities are classified along a continuum of passive, active, and constructive . Overt activities--¬such as reading, highlighting, and self-explaining--are grouped according to the hypothesized cognitive processes they engage. The framework posits that constructive activities yield the best learning, passive yield the poorest, and active is somewhere in between. Although these hypotheses are not supported by this experiment, there i

Abstract:

Pension funds play a large role in the UK pension system since the returns of the funds determine how large the total pension will be. The future retirees can choose between active and passive fund management where the active management often is more expensive. In this study 102 actively managed UK equity pension funds are analyzed in order to see if managers have sufficient skill to generate risk adjusted return to cover the cost imposed on the investors. The result implies that the active pension funds in aggregate, before expenses, hold a portfolio that imitates market returns during 2000 t

This thesis examines the use of tactile sensing for robotic contact skills. Two skills were developed which successfully tracked the contact of a plane and a sphere in the presence of positional uncertainties and varying applied forces. In the plane tracking skill, the normal force of the contact as well as a rotational moment about an axis of the sensor was tracked. In the sphere tracking skill, the normal force and positional variations lateral to the sensor were tracked. This work is significant in that it represents the first attempt, to the author's knowledge, at implementing these skills

Active and passive localization employing widely distributed sensors is a problem of interest in various fields. In active localization, such as in MIMO radar, transmitters emit signals that are reflected by the targets and collected by the receive sensors, whereas, in passive localization the sensors collect the signals emitted by the sources themselves. This dissertation studies optimization methods for high precision active and passive localization. In the case of active localization, multiple transmit elements illuminate the targets from different directions. The signals emitted by the tra

Despite the extensive research within the field of resource management in monostatic multifunction radar, the resource management techniques for a multifunction radar network are still in their infancy.

This is a gap which has been identified and is the aim of this thesis to explore.

Specifically, it consists of the developments and applications of two groups of devices: the optical phase en/decoders and the tunable fibre Bragg gratings based on an S-bending technique. The advantage of an S-bending tuning FBG is that its central wavelength is invariant as the linear strain gradient along the FBG is altered. Two new devices are developed by embedding a pair of FBGs in a single uniform beam for S-bending. One is the tunable dispersion compensator with a wide tuning range, and the other is a tunable pure dispersion s

To add damping to structures, viscoelastic materials (VEM) are added to structures. In order to enhance the damping effect of the VEM, a constraining layer is attached, creating a passive constrained layer damping treatment (PCLD). When this constraining layer is an active element, the treatment is called active constrained layer damping (ACLD). Recently, the investigation of ACLD treatments has shown it to be an effective method of vibration suppression. In this work, two new hybrid configurations are introduced by separating the passive and active elements. In the first variation

Active versus passive investing is a popular topic within the investment community and beyond. In particular, many are concerned with fund flows in and out of active and passive investments. Existing research suggests that recent returns are a reason for the capital flow from active to passive and that fees also impact flows negatively. With U.S. equity mutual funds as a proxy for active investing and U.S. equity ETFs as a proxy for passive investing, I show that prior month flows have a positive and significant relationship with current flows for both ETFs and mutual funds, as well as for flo

Abstract:

Les oxydes d'azote (NOx) ont un impact considérable sur l'environnement. La combustion en est l'une des sources principales. Dans la plupart des configurations réelles, la combustion a lieu dans des écoulements turbulents. L'interaction entre la chimie de formation des NOx et la turbulence est l'une des clés du problème et sera étudiée via le mélange et le champ de taux d'étirement. En s'inspirant de la combustion pulsée, il est possible de provoquer la création de structures à grande échelle dans un écoulement et d'étudier l'influence de ce procédé sur la formation des NOx. La première soluti

Abstract:

Episodic memory refers to context based explicit memory and shows vast improvements during middle childhood. In this study, episodic encoding was manipulated using stimuli that were hypothesized to require active or passive processing. Nine to eleven-year-old children were presented with a recall task using lower resolution (active processing) and clear (passive processing) images. It was hypothesized that children would recall more low resolution images than clear images. Executive function ability was also assessed to investigate possible contributions to performance. Furthermore, this study
