Abstract: A method can include establishing, by a computing system, a secure electronic network connection to an electronic agent running configured to access the dataset to dynamically generate the metadata related to the dataset on a client computing system. A method can include receiving, by the computing system, from the electronic agent via the secure electronic network connection, metadata related to a dataset, the metadata comprising a plurality of attributes of the dataset and a summary of the dataset. A method can include applying a valuation model to the metadata to determine an estimated value of the dataset, the valuation model comprising a machine learning model trained using marketplace data comprising sales prices and attributes of one or more datasets, wherein the model is trained to output the sales prices of the one or more datasets. A method can include determining, an estimated value of the dataset.

Abstract: A method and system for delivering dynamic web pages in the INTERNET. Compiled programs embedding static queries to a database are stored on a server computer; view templates with HTML tags defining the layout of corresponding dynamic web pages and data tags instructing where and how to include each record of the query result into the respective dynamic web page are further stored on the server computer. When a dynamic web page must be distributed, the corresponding program is run, and the query result is stored into a shared memory structure. The query result is combined with the corresponding view template, by replacing the data tags with the associated records in the shared memory structure. The resulting web page is then distributed to client computers of the network.

Abstract: The device for locating the epidural space being proposed is based on the depression existing at that space. It consists of a circuit and a canula with a corresponding coaxial needle. Once the circuit is energized, a puncture is carried out with the canula up to the surroundings of the yellow ligament. The canula is fixed at this position by means of a fixer element which is displaced along the canula up to the patient's back. The needle is inserted into the canula and by careful manual force or punching it continues until reaching the epidural space. When that happens, the circuit is triggered due to the existing depression at the epidural space, one or more alarms or signals and an electromagnet being thereby activated, the latter attracting the needle and a sleeve into which it is coaxially positioned. By frictional engagement to one another, the needle and sleeve move farther through the canula in response to the activated electromagnet.
