Factors influencing laboratory vibratory compaction
… based on vibration exist for the control of compaction, to what soil types these tests are applicable and what the factors are which affect laboratory vibratory compaction. The study revealed that extensive research has been carried out in the USA and Europe, where standard laboratory …

The Impact of Rolling Dynamic Compaction
Rolling dynamic compaction (RDC) consists of a non-circular module of 3, 4 or 5 sides, that rotates as it is towed, causing it to fall to the ground and compact it dynamically. There is currently little guidance available for geotechnical practitioners regarding the depths of improvement that are …

Compaction of chromatin in Saccharomyces cerevisiae
… yeast linker histone homologue, Hholp, and the compaction of the yeast genome during stationary phase. The relative gene content of condensed chromatin, fractionated and isolated by sucrose gradient ultracentrifugation from stationary and exponential phase cultures was compared using genome-wide …

Thermomechanical modelling of powder compaction and sintering
… and based on micromechanical modelling of the compaction process of granulates. Micromechanics is shown to yield an upper-bound estimate to the compaction curve of a granular material, which compares well with other models and finite element simulations. The parameters of the thermomechanical …

Shear and normal stresses in uniaxial compaction.
… were chosen to investigate the uniaxial compaction of particulate solids. Dentritic and cubic sodium chloride were chosen as plastically deforming, dicalcium phosphcte and sugar as fragmentary and styrocell, homopolymer and copolyrinier as non-compactable materials. The uniaxial …

Warm compaction of aluminium alloy Alumix 123
… P/M alloy Alumix 123 by application of a warm compaction process. They were achieved by investigating the effect of (a) compaction pressure/temperature, (b) admixed lubricants (e.g. Acrawax C and Kenolube P11) on green/sintered density and mechanical properties of compacts. It was found that …

Digital Simulation of Compaction in Sedimentary Sequences
A compaction model which incorporates energy transport with fluid flow to investigate the role of three-dimensional loading and thermal expansion of fluid in generating the excess pore pressure in nonhomogeneous sedimentary sequences is developed. In this model, physical properties of fluid and …

Direct tablet formation by electrospinning and compaction
… an electrospinning operation and subsequent compaction. Theoretical simulations of the electrospinning were run to predict physical system performance, and a proof-of-concept device was designed, produced and tested. The process was demonstrated to be theoretically scalable to levels of …

Pharmaceutical tablet compaction : product and process design
… can be controlled by selection of excipients and compaction parameters. A systematic strategy for formulation and process design of pharmaceutical tablets is proposed. A modified nanoindenter method was used to test the mechanical behavior of diametrally compressed excipient granules. X ray micro …

Algorithms for circuit layout compaction of building blocks
Compaction is the CAD tool used to pack rough sketches or symbolic diagrams to produce error free IC layouts. With the ever increasing complexity of VLSI circuitry, the building block approach becomes very important for custom VLSI design. A graph-theoretic compaction algorithm is developed for the …

Output space compaction for testing and concurrent checking
In der Dissertation werden neue Entwurfsmethoden für Kompaktoren für die Ausgänge von digitalen Schaltungen beschrieben, die die Anzahl der zu testenden Ausgänge drastisch verkleinern und dabei die Testbarkeit der Schaltungen nur wenig oder gar nicht verschlechtern. Der erste Teil der Arbeit …

Fiber Reinforcement Compaction In Resin Injection Pultrusion Process
… resin flow through the fiber reinforcement when compaction of the fibers is also taken into account. This study basically focuses on defining the wetout criteria for a particular set of processing parameters. It also presents the impact of the changes in these processing parameters on the …

A numerical compaction model of overpressuring in shales
A one-dimensional, numerical model of sediment compaction has been developed using porosity, velocity of sediment particles, and depth of the evolving basin as master variables. The governing set of nonlinear, partial differential equations are solved by a finite difference scheme devised to be …
