Abstract: Disclosed is a system and method for a 24-GHz phased array for indoor smart radar comprising at least 6 horizontally placed antenna elements as a vertically placed 5-element series-fed microstrip patch array. The beam of the phased array can be continuously steered on the H-plane to different directions through a novel vector control array. Each element can adjust the phase and amplitude of the corresponding element of the horizontally placed linear array. The phased array system of the present invention may be fabricated on a single printed circuit board (PCB), and PIN diodes are used to realize beam steering by modulating the decomposed received signal. In order to compensate for the loss of the vector control array and reduce the noise figure, six low noise amplifiers (LNAs) are also used in the array. The present invention has the ability to continuously steer the beam on the H-plane.

The kit can further include a third container having a third media for sample testing with the sensor. The third media can comprise X mL of 0.01 M KOH. The third container can receive Y mL of saliva to complete a Z mL total volume in the third container prior to sample testing.

Abstract: A microwave-induced heating of CNT filled (or coated) polymer composites for enhancing inter-bead diffusive bonding of fused filament fabricated parts. The technique incorporates microwave absorbing nanomaterials (carbon nanotubes (CNTs)) onto the surface or throughout the volume of 3D printer polymer filament to increase the inter-bead bond strength following a post microwave irradiation treatment and/or in-situ focused microwave beam during printing. The overall strength of the final 3D printed part will be dramatically increased and the isotropic mechanical properties of fused filament part will approach or exceed conventionally manufactured counterparts.

Abstract: Methods for optimization of liquid oil production by huff-n-puff in shale reservoirs to achieve an improved (and optimal) oil recovery factor. The process determines and utilizes the optimum huff and puff times, number of cycles and soaking time under practical operation and reservoir conditions. The huff time in the process is a period so long that the pressure near the wellbore reaches the set maximum injection pressure during the huff period. The puff time in the process is the time required for the pressure near the wellbore to reach the set minimum production pressure during the puff period. Soaking is typically not necessary during the huff-n-puff gas injection in shale oil reservoirs. The number of huff-n-puff cycles is determinable by the time in which the economic rate cut-off is reached.
