Abstract: A system, method and computer-readable medium provide secure communication between a first and a second computer system based on supersingular isogeny elliptic curve cryptography. The first computer system and the second computer system each determine kernels KA and KB including computing mP+nQ by accessing a lookup table stored in a memory that contains a range of doubles of an end point of the respective kernels, where P and Q are points on the public elliptic curve and m and n are integers. The first computer system and the second computer system compute secret isogenies by determining a respective kernel KBA and KAB using mixed-base multiplicands with a single inversion, including computing the respective kernel KBA and KAB by converting the multiplicands to base 32, and computing scalar multiplications using the base 32 multiplicands.

Abstract: A zinc-based nanohybrid was prepared using a facile wet chemistry process. This nanohybrid has zinc oxide nanostructures connected to zinc phthalocyanine molecules via biologically important ligands. In addition, this nanohybrid has photocatalytic properties and photodegrades water pollutants, such as methyl orange.

Abstract: A method of making an electrically conductive cotton material by incorporating conductive poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) films into a base cotton substrate by drop casting or dip coating. Unlike most conventional methods that have typically included the use of templates such as metal oxide, carbon and/or silica nanoparticles, the polymerization of PEDOT:PSS in this method is not template-assisted. The amount of PEDOT:PSS used in the fabrication process controls the conductivity and sheet resistance of the conductive cotton material, and can be varied by the number of repeated drop casting or dip coating cycles.

Abstract: A system and associated methodology determines the 3D position of a Global Navigation Satellite System (GNSS) receiver using travel times of a signal. In addition, the system determines a clock offset between the GNSS receiver and satellites. The system finds the required coordinate component while minimizing the computational requirement.

Abstract: A boundary regulation detection method and system that stores one or more dates and times and predetermined areas corresponding to an event, determines a user current location and current date and time, generates an alert in response to determining that the current date and time corresponds with the date and time, analyzes whether the user current location is not within a predetermined area and sends to authorized individuals the user location. The method based on the current date, time and user location issues appropriate alerts.

Abstract: A boundary regulation detection method and system that stores a list of events, stores one or more dates and times and predetermined areas corresponding to each event, stores one or more predetermined areas determined as a function of a particular event, determines a user current location and current date and time, generates an alert in response to determining that the current date and time corresponds with the date and time, analyzes whether the user current location is not within a predetermined area and instructs the user to enter the predetermined area if the user current location is not within the predetermined area. The method based on the current date, time and user location issues appropriate alerts.
