Multi-sensor platforms for the geophysical evaluation of sensitive archaeological landscapes. Evaluation of and improvement of the MSP40 mobile sensor device for rapid multi-technique and low impact measurements on archaeological sites with vulnerable soil.
… rates but has not considered the physical impact on the soil. The Geoscan Research Mobile Sensor Platform (MSP40) was intended to improve survey efficiency and remain a lightweight system. The platform can collect two earth resistance configurations that show directional variation of the …

Assessing Recreation Impacts to Cliffs in Shenandoah National Park: Integrating Visitor Observation with Trail and Recreation Site Measurements
… use of cliff areas has led to natural resource impacts, including marked decreases in size and vigor of known rare plant populations. Despite the clear ecological value and potential threats to the natural resources at cliff areas in the park, managers possess little information on visitor use …

Low-Impact Profiling of Streaming, Heterogeneous Applications
… a heterogeneous system. TimeTrial performs low-impact measurements by dedicating computing resources to monitoring and by aggressively compressing performance traces into statistical summaries guided by user specification of the performance queries of interest.

The Mercurian magma ocean, first crust, and implications for planetary formation mechanisms
… require silicate removal, perhaps by a giant impact, to create the planet's large core fraction. The earliest crusts expected in a giant impact scenario are discussed in comparison to the endogenous model. We find that the endogenous model can produce a large core with either a plagioclase …

High-Velocity Microparticle Impact for Analytical Modelling of High-Strain-Rate Mechanics and Material Behavior
… and observing high-velocity micron-scale impacts against various materials is the focus of this work. This technique, the laser-induced particle impact test (LIPIT), is capable of accelerating microparticles to supersonic velocities to achieve strain-rates up to 108 s-1. The platform also …

Structure and Properties of Polymer Blends
… technique (Rheovibron), stress-strain and impact measurements in the solid phase at room temperature (20 +- 1°C). The results showed that tensile strength, elongation at break, impact strength and tan§ (20°C) decreased with increasing PVC, PP and PS content. It was concluded that …

Structure-property characterisation of ternary phase polypropylene composites
… While the mechanical tests included tensile and impact measurements at ambient temperature, and a fracture toughness test based on the J-integral method carried out at -20 oC. EPR and glass beads were found to influence the structure and properties of polypropylene in different ways. …

Measuring and evaluating economic impact of publicly-funded research centres
… and tools to measure and evaluate the economic impact of publicly funded research centres, thus addressing calls from policymakers for greater accountability and justification for investment of public funding towards research activities. In addition to developing impact measurements tools, the …

Creating shared value: Investigating how micro-property developers in townships can collaborate with impact investors
… being access to funds. This study looks at how impact investing, an emerging funding model can be used to address this challenge. Impact investing can be described as a cross-sectional initiative that involves the professional participation of various stakeholders; to drive social …
