This paper presents a framework for augmented reality. Head tracking is accomplished using a head-mounted camera, which uses an optical flow based algorithm to track patterns on the ceiling. The position and orientation of the ceiling need not be known a priori, and the necessary calibration, except for radial lens distortion, can be performed on the fly using simple procedures.

A Bearing-Only TMA running on a submarine, which can exploit the crossbearing effect from sensors installed at different locations needs no own manouevre for convergence, if the parallax between the involved bearings exceeds a certain value. In this paper we discuss some results for the cases where data from a Towed Array is fused with data from an on-board sensor or the data of 2 on-board sens...

Head-mounted projection display (HMPD) technology, as an alternative to conventional head mounted displays (HMD), offers the potential of designing wide field-of-view (FOV) optical see-through HMDs. Due to multiple passes through a beamsplitter, however, existing HMPD designs suffer from low luminance efficiency and thus the displayed image is lack of brightness and contrast. The design of a po...

The optical and electrical performances of varied configurations visually attractive mosaic cubical luminescent solar concentrator photovoltaic (LSC PV) devices have been measured. These new designs LSC PV consist four lightguides containing commercially available fluorophores with edge- bottom-mounted silicon cells. 1 cm3 component PVs are made poly (methyl methacrylate) (PMMA) doped by dyes f...

In this research, the student will explain a candidate construction for indistinguishability obfuscation, based on a recent paper by Garg et al. (FOCS 2013). This is done by first describing the main building blocks, then how these are used to build indistinguishability obfuscation for NC, and expanded to P/poly. Security and alternative constructions are very briefly discussed.

Apoptosis is a major feature in neural development and important in traumatic diseases. The presence of active caspases is a widely accepted marker of apoptosis. We report here the development of a method to study neuronal apoptotic death in whole-mounted brain preparations using fluorochrome-labeled inhibitors of caspases (FLICA). As a model we used axotomy-induced retrograde neuronal death in...

An implantable glucose microbiosensor that utilizes an electrodeposited redox polymer/glucose oxidase (GOX) sensing membrane and a highly hydrophilic poly (4-vinyl pyridine-co-acrylic acid) (PVP-PAC) overcoating as an analyte-regulating membrane has been developed. A gold microelectrode was electrodeposited with the redox polymer/GOX composite sensing membrane. Two polymers, a hydrophobic poly ...
