Abstract: A process for producing a heavy metal mediated biochar composite using silicate solidification. Hydrocharis dubia has excellent enrichment of manganese ions in sewage, and is used to treat sewage water to adsorb heavy metals such as lead, manganese and zinc contained in the sewage water into roots, stems and leaves thereof, which are pyrolysed in stages at high temperature with activated red mud and bentonite prior to blending with zeolites, to produce said heavy metal mediated biochar composite; the process significantly extends the migration time of heavy metals, increases the stability of heavy metals and reduces the risk of environmental pollution by heavy metal leakage.

Abstract: A system and method for generating a 3D model and/or map of a geographic region is disclosed. A computer designates a geographic region and a number of aircraft, and partitions the designated geographic region into sub-regions, creates waypoints within each sub-region, and plans missions for each aircraft to fly to each waypoint and take pictures. The aircraft are configured to accept and perform missions from the computer, and the computer receives images from the aircraft, assigns each image to a sub-region, and transmits each sub-region and images, as well as instructions, to the computing resource. The computing resource executes the instructions, which perform 3D reconstruction and generate orthophotos and 3D models. The 3D reconstruction comprises trimming distorted portions of the orthophotos and 3D models, and merging the orthophotos and 3D models from each sub-region into a 3D model and/or map of the geographic region.

Abstract: The present invention discloses a network handwriting instrument. The network handwriting instrument comprises a handwriting table. A column is fixedly mounted in a middle position of a back side of an upper end surface of the handwriting table. A transverse column is arranged on the upper portion of a front surface of the column. An LED illumination lamp and a camera are arranged on a lower end surface of the transverse column. A horn, a power supply switch, a power supply indicator lamp and a liquid crystal touch screen are fixedly mounted from top to bottom on a lower portion of the front surface of the column, successively. According to the network handwriting instrument, a heating plate is heated up through an electric heating wire, so that the network handwriting instrument is used in winter conveniently. As the camera is focused on writing paper to shoot, so that a user can be interacted with a teacher online in real time.

Abstract: Social data obtained from social networks first undergo preliminary processing to remove the social data that do not have a workable attribute. Next, the social data go through machine learning process and stored firstly in a cache of main server and later on in a big data database that is distributed into different servers at different locations, with the purpose of better security and efficiency. When a client requests or search a certain attribute, such as location, the well processed and organized social data stored in the cache and the big data database will be searched in order to find the corresponding social data, which will then be present at a map based on such social data's location attribute. The foregoing process can be implemented as an application of a handheld device, such as cell phone, or a website that is accessible for both handheld device and computer.
