Abstract: A method, system and computer program product for dynamically establishing a client's Time Sharing Option (TSO) and/or Interactive Productivity System Facility (ISPF) session and maintaining the client's TSO/ISPF session on a zero-downtime/operating system (z/OS) host over multiple service calls. A session provisioning and maintenance (SPM) utility determines whether a TSO/ISPF session exists for a client making a request for a TSO/ISPF service. When a TSO/ISPF session does not exist for the client, session establishment is initiated by generating a TSO initialization module in a new UNIX System Services (USS) process. Session establishment involves initializing a user's own TSO address space through USS and using USS service call API's to make TSO/ISPF service call requests in the TSO address space. The SPM utility maintains the client's TSO/ISPF session over multiple service calls, bypassing the overhead of having to establish a new session for every service request which requires TSO/ISPF services.

Abstract: A non-invasive microwave analysis method determines scattered phase and/or amplitude data for a liquid in a container. A transmitter antenna transmits microwaves that scatter from the container and the liquid in the container. One or more receiver antennas convert the microwaves into microwave electronic signals that are processed to determine the scattered phase and/or amplitude data. Another non-invasive microwave screening method includes placing a container of an unknown liquid in a tank. The container is separated by a membrane from coupling liquid in the tank. Microwave radiation transmits from a transmitter antenna and scatters from the container and the unknown liquid. One or more receiver antennas convert the microwave radiation into microwave electronic signals. The microwave electronic signals are processed to determine scattered phase and/or amplitude data. A pass result or a fail result is determined based on the scattered phase and/or amplitude data.

Abstract: A microwave imaging process, and a system controlled by an associated software product, illuminate a target with microwaves from a transmitting antenna. Receiving antennas receive microwaves scattered by the target, and form microwave data. The illumination and receiving repeat over multiple transmitting antennas and multiple microwave frequencies. The microwave data is processed to form permittivity and conductivity images by selecting a background dispersion model for permittivity and conductivity. Permittivity and conductivity dispersion coefficients are determined, and permittivity and conductivity distributions are calculated, for each of the microwave frequencies. Forward solutions at multiple frequencies are determined from property distributions, and a dispersion coefficient based Jacobian matrix is determined. Dispersion coefficient updates are determined using the microwave data, and the dispersion coefficients are updated.
