Testing for smooth transition nonlinearity in adjustments of cointegrating systems

This paper studies testing for the presence of smooth transition nonlinearity in adjustment parameters of the vector error correction model. We specify the generalized model with multiple cointegrating vectors and different transition functions across equations. Given that the nonlinear model is highly complex, this paper proposes an optimal LM test based only on estimation of the linear model. The null asymptotic distribution is derived using empirical process theory and since the transition parameters of the model cannot be identified under the null hypothesis bootstrap procedures are used to approximate the limit. Monte Carlo simulations indicate a good performance of the test

Kiš’s vigilance: ethics as aesthetics in the prose of Danilo Kiš

This thesis offers a reading of the late Yugoslav writer Danilo Kiš by looking at how a particular tradition of European aesthetics and ethical philosophy (namely Levinas and Blanchot) can be compared to Danilo Kiš’s poetics. Beyond critically evaluating Kiš, I am to make connections between ethics, literature and philosophy. The major objective of my thesis is to argue that ethical is embedded as aesthetical in Kiš’s poetics as both Blanchotian and Levinasian understanding of ethics, i.e. as a non-dialectical and non-intentional movement from ‘I’ to the ‘other’ in the midst of passivity of dying (which is for both Blanchot and Levinas ‘other’ death). The thesis demonstrates that there are a number of strands in Levinas’s and Blanchot’s thought that, while differently expressed, can also be traced at work in Kiš’s writing, and which can, as such, help to elucidate certain crucial aspects of the latter. Taking into consideration Kiš’s obsessive writing on the violence of the last century – both left and right – I argue that what permeates his prose is death as both possibility and a radical impossibility consequent upon the il y a, a crucial philosophical concept in Levinas’s ethical philosophy and Blanchot’s literary ‘theory’. For this reason, the thesis aims to assert that what permeates Kiš’s prose is what Critchley terms ‘atheist transcendence’: the burden of responsibility for the death of the other human radically excludes theodicy. My research is significant in so far as conceptualisations of death to be found in continental European philosophy have hardly been directly juxtaposed with those found in Kiš’s prose. Since according to Blanchot, literature’s demand is always ambiguous and as such it exposes us to the question of being, in my thesis I analyse how this refusal of language to cease the tension of pluralism operates in Kiš’s prose as the ethical

Planar photonic crystal

We present results of guiding light in a single-line-defect planar photonic crystal (PPC) waveguide with 90° and 60° bends. The wave guiding is obtained by total internal reflection perpendicular to the plane of propagation and by the photonic band gap for the 2D photonic crystal in the plane. The results for photonic waveguiding are shown and demonstrated at 1.5 µm wavelength

Visualization of Submerged Cavitating Jet: Part One –The Phenomenon,Time-Synchronization, Photo Objectives and Sono-Luminescence

In order to study the jet structure and the behavior of cloud cavitation within time and space, visualization of highly submerged cavitating water jet has been done using 4-Quik-05 camera. This included obligatory synchronization technique and several types of lenses. The influencing parameters, such as: injection pressure, downstream pressure and cavitation number were experimentally proven to be very significant. The recordings of sono-luminescence phenomenon proved the bubble collapse everywhere along the jet trajectory. In addition, the effect of temperature on sono-luminescence was investigated

Visualization of Submerged Cavitating Jet: Part Two – Influences of Hydrodynamic Conditions, Nozzle Geometry and Visualization System Arrangement

In visualization results of highly-submerged cavitating water jet obtained by a digital camera, the influence of parameters such as: injection pressure, nozzle diameter and geometry, nozzle mounting (for convergent / divergent flow), cavitation number and exit jet velocity, were investigated. In addition, the influence of visualization system position was studied. All the parameters have been found to be of strong influence on the jet appearance and performance

Study protocol for a randomised controlled trial of internet-based cognitive-behavioural therapy for obsessive-compulsive disorder.

Obsessive-Compulsive Disorder (OCD) is a common chronic psychiatric disorder that constitutes a leading cause of disability. Although Cognitive-Behaviour Therapy (CBT) has been shown to be an effective treatment for OCD, this specialised treatment is unavailable to many due to access issues and the social stigma associated with seeing a mental health specialist. Internet-based psychological treatments have shown to provide effective, accessible and affordable treatment for a range of anxiety disorders, and two Randomised Controlled Trials (RCTs) have demonstrated the efficacy and acceptability of internet-based CBT (iCBT) for OCD, as compared to waitlist or supportive therapy. Although these initial findings are promising, they do not isolate the specific effect of iCBT. This paper details the study protocol for the first randomised control trial evaluating the efficacy of therapist-assisted iCBT for OCD, as compared to a matched control intervention; internet-based therapist-assisted progressive relaxation training (iPRT). It will aim to examine whether therapist-assisted iCBT is an acceptable and efficacious treatment, and to examine how effectiveness is influenced by patient characteristics

Demonstration of Silicon-on-insulator mid-infrared spectrometers operating at 3.8 mu m

The design and characterization of silicon-on-insulator mid-infrared spectrometers operating at 3.8µm is reported. The devices are fabricated on 200mm SOI wafers in a CMOS pilot line. Both arrayed waveguide grating structures and planar concave grating structures were designed and tested. Low insertion loss (1.5-2.5dB) and good crosstalk characteristics (15-20dB) are demonstrated, together with waveguide propagation losses in the range of 3 to 6dB/cm
