Such an instruction includes an operation code field for storing an operation code and at least one operand field, where the operand field includes an indirect addressing mode indicator for indicating enablement of an indirect addressing mode. If an indirect addressing mode is enabled, a general purpose register address is selected from an address field in an indirect register. Finally, the data processing unit addresses a selected one of the plurality of general purpose registers utilizing the general purpose register address during the execution of the operation code by the data processing unit.

Abstract: A vector having a plurality of elements is stored in an input storage area, wherein the vector elements are stored in a first pattern. Thereafter, the elements are transferred, in a first order, from the input storage area into a vector register interface unit. From the vector register interface unit, the elements are transferred to an output storage area and stored in addressable locations in one of a plurality of preselected patterns. The input storage area may be implemented with cache memory or a register array. The output storage area may be implemented with a cache memory or a register array. The first pattern in the input storage area may include alternating real and imaginary elements. The plurality of preselected patterns may include a reversed order pattern, or a separation of real and imaginary elements into two vector registers.

Abstract: An under-sea-water electric discharge generator includes a source of stored electrical energy connectable through solid state switch means to a cable extending to a number of pairs of electrodes to be towed under sea-water. The switch means comprises an inductor in series with five main branch circuits: a capacitor discharge branch includes a plurality of SCRs connected in series and a sub-branch of RC elements for gate control with one RC element across each but an end one of the SCRs; a reverse discharge branch includes a plurality of diode means, one across each SCR. Diodes across the gate-cathode circuit of each but said one SCR protect against reverse negative voltage during reverse discharge. Static, dynamic, and over voltage branches parallel the SCR branch with one element of each (resistor, RC element, thyrector) across each SCR.

Abstract: The porous displacement piles comprising (a) closed-ended pipe piles with small holes and or narrow slots, filled with compacted sandy soil, (b) closed-ended porous pipe piles such as closed-ended pipe pile with very small holes and or very narrow slots, and (c) a precast prestressed porous concrete piles are driven through inside the already driven non-displacement hollow pipe piles in a grid pattern to create excess pore-water pressures generally ranging between 50 and 1500 kPa in cohesive soils, which begin dissipating through inside the porous displacement piles to rapidly consolidate and densify the said cohesive soil. The porous displacement piles are designed for permitting free flow of the pressurized pore-water and to prevent migration of particles of cohesive soil into the porous displacement pile using filter design criteria or verified by laboratory tests. These piles when driven in sandy soils densify sandy soils instantaneously.

To determine the three-dimensional coefficient of consolidation and coefficient of consolidation in horizontal direction, the flexible ring consists of all above structural components of expandable jacket except that a filter fabric or paper is wrapped around the cylindrical specimen, and then rubber membrane is mounted surrounding the filter paper or paper. The calibration device for calibration of the expandable jacket and flexible ring shall provide the magnitude of correction to be made in deviator stress and lateral resistance provided by the rubber bands or rings during the test.

Abstract: A test device has been invented for determining three-dimensional consolidation properties of soils, using a flexible ring permitting displacements and dissipation of the excess pore pressures in both horizontal and vertical directions, and affording determination of coefficients of consolidation in the horizontal and vertical directions, and the modulus of elasticity. The flexible ring consists of a filter fabric around the soil specimen, a rubber membrane around the filter, circular shaped segmented metal plates around the membrane and rubber bands or rings around the plates. Both the incremental loading or triaxial type loading systems can be used with this device. A calibration device for calibration of the flexible ring is used to determine the modulus of elasticity of elastic elements, required for calculating lateral resistance provided by the flexible ring during the test.

Abstract: Standard test methods using a fixed ring for determining one-dimensional consolidation properties of soils represent a subsurface condition where settlement and dissipation of excess pore pressure is possible only in vertical direction. This subsurface condition never occurs, as settlements and dissipation of excess pore pressures always occur in horizontal and vertical directions. Dr. Ramesh Gupta has invented a test device for determining three-dimensional consolidation properties of soils, using a flexible ring permitting displacements and dissipation of excess pore pressures in both horizontal and vertical directions, and affording determination of coefficients of consolidation in horizontal and vertical directions including three-dimensional coefficient of consolidation, and modulus of elasticity. The test device consists of a flexible ring consisting of filter fabric around the soil specimen, rubber membrane around the filter, circular segmented metal plates around the membrane and rubber bands or rings around the plates. Both incremental or triaxial type loading can be used with this device.

Abstract: During triaxial compression test, a soil specimen experiences reduction of its height with increase in its diameter. New cross-sectional area is calculated assuming uniform increase in diameter. This condition is seldom met in actual soil specimens, because specimen undergoes non-uniform increase in diameter and very often with localized bulging in specimen affecting the accuracy of calculation of deviator stress, shears strength and volume change characteristics. The expandable jacket included in this invention consists of circular segmental metal plates wrapped around the soil specimen and elastomeric rubber bands or rings around the segmental plates to permit uniform radial expansion and maintain uniform diameter of the specimen during the test and thereby providing accurate values of deviator stress, volume change characteristics and shear strength of soil specimen. The calibration device for calibration of expandable jacket shall provide the magnitude of correction to be made in deviator stress.

Abstract: During triaxial compression test, a soil specimen experiences reduction of its height with simultaneous increase in its diameter. For calculation of new cross-sectional area, it is always assumed that the specimen deforms as a cylinder with uniform increase in diameter through its height. This condition is seldom or never met in actual soil specimens, because specimen undergoes non-uniform increase in diameter through its height and very often with localized bulging in specimen affecting the accuracy of calculation of magnitude of deviator stress at any instant of time during the test. Non-uniform increase in diameter through its height with often localized bulging affects the real strength and volume change characteristics, and how much this effect of non-uniform lateral increase in diameter changes these properties remains unknown. The expandable jacket wrapped around the soil specimen for performing the triaxial compression test included in this invention, shall maintain uniform diameter of soil specimen through its height and shall provide accurate prediction of deviator stress, volume change characteristics and strength of soil specimen. The calibration device for calibration of expandable jacket shall provide the magnitude of correction to be made in deviator stress at various levels of axial and lateral strains.
