Abstract: Disclosed is an inter-cell interference mitigation method using a spatial covariance matrix (SCM) estimation method in a multi-input multi-output (MIMO) orthogonal frequency division multiplexing (OFDM) communication system for mitigating interference between asynchronous cells. The inter-cell interference mitigation method includes extracting a reference symbol (RS) of a received OFDM symbol and performing channel estimation, estimating an initial SCM using the RS signal and the channel estimation result, applying time-domain sinc type weighting to the initial SCM and applying an SCM, and demodulating a data symbol with mitigated inter-cell interference using the channel estimation result and the estimated SCM.

Abstract: Ray tracing a three-dimensional scene using a grid. One example embodiment is a method for ray tracing a three-dimensional scene using a grid. In this example method, the three-dimensional scene is made up of objects that are spatially partitioned into a plurality of cells that make up the grid. The method includes a first act of computing a bounding frustum of a packet of rays, and a second act of traversing the grid slice by slice along a major traversal axis. Each slice traversal includes a first act of determining one or more cells in the slice that are overlapped by the frustum and a second act of testing the rays in the packet for intersection with any objects at least partially bounded by the one or more cells overlapped by the frustum.

Abstract: Lesions caused by insects feeding on plants are associated with the generation of regions of blue-green fluorescence in such as the cotton boll carpel wall and in the lint region. The present disclosure now provides methods and devices to rapidly and non-invasively detect and measure the insect-related fluorescence and relate the fluorescence generated to the likelihood of insect damage in a crop. In particular, the methods are related to stink bug damage in the cotton plant, but are also suitable for the detection of insect-related damage of any plant. The methods of detecting insect-induced damage in a target plant tissue may comprise exposing a target plant or a fragment thereof, to an ultraviolet or violet light; and detecting an ultraviolet light-induced fluorescence from the target plant or the fragment thereof, thereby indicating the presence of insect-related plant damage.

Abstract: Green to transmissive soluble electrochromic polymers are conjugated polymers having a plurality of repeating units where repeating units are a plurality of substituted dioxyheterocycle based donor groups coupled to an acceptor group. The conjugated polymer absorbs radiation within a first band of the visible spectrum and a second band of the visible spectrum when in a neutral state resulting in a green color and is transmissive when in an oxidized state. The polymers are soluble allowing processing of films and coatings from solution.

Abstract: A system for real-time solar observation comprises an optical detector operable to detect sunlight and to produce image data from detected sunlight, a shadow detector operable to produce image data relating to a shadow cast by a reference object, and a controller operable to receive image data from the optical detector and from the shadow detector. The controller is operable to determine at least one of a sunrise period, a midday period and a sunset period in dependence upon received image data.
Abstract: High quantum yield InP nanocrystals are used in the bio-technology, bio-medical, and photovoltaic, specifically IV, III-V and III-VI nanocrystal technological applications. InP nanocrystals typically require post-generation HF treatment. Combining microwave methodologies with the presence of a fluorinated ionic liquid allows Fluorine ion etching without the hazards accompanying HF. Growing the InP nanocrystals in the presence of the ionic liquid allows in-situ etching to be achieved. The optimization of the PL QY is achieved by balancing growth and etching rates in the reaction.
