Abstract: In various embodiments, systems and methods for Multi-Tenant In-Memory Database access to an application program accessing an object-oriented database (OODB) are disclosed. Embodiments may include: connecting, by a processor, the application program to a data repository for a database; generating, by the processor, a first Firm for a first tenant; placing, by the processor, an address of a first object of the first Firm into a knowledge base pointer associated with the first tenant; placing, by the processor, an address of a main database object of the database into a pointer in an object of the first Firm; and accessing, by the processor, the first Firm through the knowledge base pointer and the database through the pointer object of the first Firm.

Abstract: Embodiments of the invention relate to memory management methods and systems for object-oriented databases (OODB). In an embodiment, a database includes a plurality of memory-mapped file segments stored on at least one nonvolatile memory medium and not in main memory. An application program connects to the database with a plurality of writing processes to simultaneously write to an in-memory database, each writing process updating its own disk-based logfile, such that the effective disk writing speed is substantially increased and lock conflicts reduced.

Abstract: An arrangement is provided for improving the yield of potato crops. The arrangement includes a bed, a plurality of pairs of parallel rows of potato plants, and a drip irrigation tape. The bed is provided for multiple rows of potato plants. The plurality of pairs of parallel rows of potato plants in the bed have an inter-row gap between the rows in each pair of rows spaced from one another sufficiently to provide a moisture permeable agronomic soil corridor between the rows in each pair of rows to provide a supply of water to a root zone of each row within each pair of rows of potato plants while maintaining aerated soil within and above the agronomic soil corridor to reduce excessively wet conditions adjacent the crop canopy and a solar light corridor provided between adjacent pairs of rows to provide increased solar energy to the potato plants.

Abstract: A fluid delivery and control system is provided for a fluid delivery line having elastic components. The system includes a pressure sensor, an electronically controlled valve, processing circuitry, and computer program code logic. The pressure sensor is operative to detect fluid pressure within a fluid delivery line. The electronically controlled valve includes an adjustable flow regulating aperture disposed in the line, interposed along a linear flow axis, and operative to regulate fluid flow through the line. The processing circuitry communicates with the pressure sensor and the electronically controlled valve. The computer program code logic is executed by the processing circuitry and is configured to generate an output signal. The output signal comprises an operating parameter of at least one of the pressure sensor and the electronically controlled valve to adjust flow capacity of the flow regulating aperture of the valve to dissipate pressure oscillations within the fluid delivery line.
