Sustainable methods for managing waste associated with people and animals have been proposed in the past. Black soldier fly, Hermetia illucens (L.), larvae represent one of the more promising methods. Larvae reduce dry matter, bacteria, offensive odor, and house fly populations. Prepupae can be used as feedstuff for livestock. However, it is not known if such a method results in the proliferati...

This paper presents the application of the Artificial Neural Network (ANN) for prediction of axial capacity of a driven pile by adopting data collected from several projects in Indonesia and Malaysia. As many as 300 data were selected for this study. In this study, ANN was set and trained to predict the axial bearing capacity from high strain dynamic testing, i.e. Pile Driving Analyzer (PDA) da...

Abstract: According to the Winkler assumption, the form of the pile constraint could be simplified as bottom fixing and top free. Considering the influence from resistance of soil around pile, the equations on calculated length for buckling stability of steel pipe pile when the portions along the pile length were constrained in the uniform foundation and the layered foundation were respectively...

Polyembryony is a unique mode of development in which multiple genetically identical embryos develop from a single egg. In some polyembryonic species a proportion of the embryos develop into soldier larvae, which attack competitors in the host. We studied the development of the polyembryonic wasp Copidosoma koehleri in its host Phthorimaea opercullela. We dissected hosts parasitized by either v...

Future capabilities of battle command systems and networked systems will increase Soldier situational awareness by providing access to information from various networked assets. We conducted a series of experiments at the United States Army Research Laboratory in Adelphi, MD and at C4ISR On-the-move (OTM) at Ft. Dix, NJ. Based on the quality of service of battle command systems, the Soldier wil...

Pile driveability analyses for offshore platforms require a unique set of criteria, which may not normally be associated with other pile foundation installations. The selected hammers, pile makeup details and soil profile must be carefully reviewed, as these factors will determine if pile installations will be successful. The most important of the variables to establish is the expected Soil Res...

ABSTRACT This study presents an investigation of the interaction effect of one loaded pile on a neighboring pile under transient dynamic loadings. Analyses are carried for non homogeneous soils. The hybrid boundary element formulation is used to represent boundary integral representation of soil domain and pile equations represented by linear structural components. The formulation is presented ...

The use of embedded pile elements provides a convenient approach that may save significant modelling time in the simulation of piled foundations. A back-analysis of an Osterberg-cell (O-Cell) load test on a 45 m long pile is presented to illustrate some of the advantages of using structural embedded elements. Comparisons with other modelling approaches for piled-raft foundations have showed goo...

Model tests were carried out in dry silica sand under pile loading and visualizing observation to investigate the behavior of a pile group. The pile group consisted of nine cylindrical model piles of 40 mm in diameter in most tests or three rectangular parallelepiped model piles in the visualizing observation. Pile spacings of 200 mm and 100 mm between pile centers were used in the models. Tact...
