Abstract: A family of new crystalline molecular sieves designated SSZ-91 is disclosed, as are methods for making SSZ-91 and uses for SSZ-91. Molecular sieve SSZ-91 is structurally similar to sieves falling within the ZSM-48 family of molecular sieves, and is characterized as: (1) having a low degree of faulting, (2) a low aspect ratio that inhibits hydrocracking as compared to conventional ZSM-48 materials having an aspect ratio of greater than 8, and (3) is substantially phase pure.

Abstract: A vehicle safety analytics and routing system can be used to identify high risk areas and to assist in routing vehicles. The vehicle safety analytics and routing system brings together a variety of vehicle incident data that can be used in identifying high risk areas and in predicting risks for a vehicle. The routing aspect of the system uses vehicle incident data to assess the distribution of risk over a geographic area and to calculate risks associated with different potential vehicle routes. The calculated risks can be used to route vehicles around high risk intersections and stretches of road.

Abstract: A method is disclosed making a molecular of TON framework type having unique properties. The method uses 1,3,4-trimethylimidazolium cations as a structure directing agent and a combined source of silicon and aluminum selected from alumina-coated silica and aluminosilicate zeolites. The obtained molecular sieve can be used in processes for dewaxing paraffinic hydrocarbon feedstocks.

Abstract: A novel synthetic crystalline aluminogermanosilicate molecular sieve material, designated SSZ-116, is provided. SSZ-116 can be synthesized using 3-[(3,5-di-tert-butylphenyl)methyl]-1,2-dimethyl-1H-imidazolium cations as a structure directing agent. SSZ-116 may be used in organic compound conversion reactions and/or sorptive processes. This disclosure also relates to the structure directing agents used in the methods for making the SSZ-116 material as well as the synthesis method used to prepare such structure directing agents.

Abstract: A method for evaluating a securing system for a floating structure, where the method includes collecting a plurality of metocean data from a plurality of metocean sensor devices during a current time period coinciding with a field operation, where the field operation is conducted from the floating structure that is stabilized by the securing system. The method can also include evaluating the metocean data using a plurality of algorithms. The method can further include determining, based on evaluating the metocean data, a condition of the securing system at the current time period.

Abstract: A method is described for generating a subsurface model using stochastic full waveform inversion by receiving a seismic dataset representative of a subsurface volume of interest; performing stochastic full waveform inversion of the seismic dataset to generate a long wavelength subsurface model; and performing full waveform inversion of the seismic dataset using the long wavelength subsurface model as a starting model to generate an improved subsurface model. The method may further include performing seismic imaging of the seismic dataset using the improved subsurface model to generate a seismic image and identifying geologic features based on the seismic image. The method may be executed by a computer system.

Abstract: A method of waste treatment includes treating partially-dewatered matrix with a first electron-beam radiation dose. The treated partially-dewatered matrix is transferred to a digester where the treated partially-dewatered matrix is subjected to anaerobic digestion. Biogas is recovered from the treated partially-dewatered matrix during the anaerobic digestion. The treated partially-dewatered matrix is dried and subjected to a second electron-beam radiation dose.

Abstract: Provided herein are portable apparatus as well as methods of analyzing a fluid using these portable apparatus. In some embodiments, the injection fluid can contain a polymer, but a polymer is not necessary. For example, the portable apparatus and methods may be used to determine viscosity, long term injectivity, filter ratio, or any combination thereof of the injection fluid. Advantageously, the surrogate core is temperature controlled.
