Filed: 2019-05-22
Abstract: A method for producing engineered soil comprising selecting a site for manipulation, determining reference parameters of the site, supplying an amount of first soil material, determining characterising parameters of the first soil material, and treating the first soil material to obtain engineered soil with parameters which are substantially similar to or an improvement upon the reference parameters of the site. The characterising parameters may exceed one or more Environmental Assessment Levels (EAL) and these are calculated by a hydrogeological risk assessment of the site. The reference parameters may be estimated levels of metals or metalloids, total petroleum hydrocarbons (TPH), polycyclic aromatic hydrocarbons (PAH), total organic carbons, pH and general inorganics such as asbestos. Ideally a second soil is mixed with the first soil and preferably the engineered soil is environmentally safe. Also claimed is an engineered soil composition comprising a first soil material with characterising parameters substantially similar to or an improvement upon reference parameters of a site. An engineered soil composition comprising a first soil material and an effective amount of a second soil material, wherein the composition has the parameters of a site is also claimed.

Title: Adaptive load coalescing
Inventor: MBOU EYOLE
IPC: G06F9/38
Filed: 2020-05-06
Abstract: In response to a load request specifying a data item to retrieve from memory, a series of data items (e.g. cache line) comprising the specified data item are retrieved. Load requests are buffered prior to being carried out. Coalescing circuitry determines for the load request and a set of one or more other load requests buffered in the pending load buffer circuitry 14 whether an address proximity condition is true. The address proximity condition is true when all data items identified by the set of one or more other load requests are comprised within the series of data items. When the address proximity condition is true, the set of one or more other load requests are suppressed. Coalescing prediction circuitry 18 generates a coalescing prediction for each load request based on previous handling of load requests by the coalescing circuitry (e.g. history).

Patent GB-2595122-A (GB)
Title: Method and apparatus
Inventor: JAMES EDWARD GEACH
IPC: G06N3/02
Filed: 2019-08-13
Abstract: The invention relates to a method and apparatus for predicting images in the visible-infrared band of a region of the Earth's surface that would be observed by an Earth Observation (EO) satellite or other high-altitude imaging platform, using image data from radar reflectance/backscatter of the same region. A neural network, possibly having a generator and a discriminator, is trained to produce a mapping model. Additional information such as surface elevation and sun angle could be used in the training process. The method and apparatus can find application when the view between an optical imaging instrument (e.g. a camera) and the ground is obscured by cloud that is opaque to electromagnetic (EM) radiation in the visible-infrared spectral range, but is transparent to EM radiation in the radio-microwave part of the spectrum. Regular, uninterrupted monitoring of the Earth's surface is important for a wide range of applications, from agriculture (e.g. assessing crop growth) to defence (e.g. identifying military activity).
