Mathematical model of plant nutrient uptake by Roose, T

“…The water uptake model shows that the water saturation can develop pseudo-steady-state wet and dry zones in the rooting region of the soil. The dry zone is shown to stop the movement of nutrient from the top of the soil to the groundwater. …”

Coseismic and postseismic slip of the 2005 Mw8.6 Nias‐Simeulue earthquake : spatial overlap and localized viscoelastic flow by Qiu, Qiang, Feng, Lujia, Hermawan, Iwan, Hill, Emma M.

“…This localized viscoelastic flow coincides with a low-velocity zone below Toba volcano, as imaged by tomography studies; it is possible that the viscoelastic flow beneath the volcano accelerated following this event.…”

Nonlinear dynamic analysis of a piezoelectric energy harvester with mechanical plucking mechanism by Noh, Jinhong, Bae, Sungryong, Yoon, Yong-Jin, Kim, Pilkee

“…For periodic plucking, successful synchronization between the motions of the piezoelectric energy harvester and the rotating plectrum must occur within a limited contact zone. Otherwise, dynamic interferences often cause the plectrum to fail to pluck the energy harvester exactly within the contact zone. …”

Long-term slip rate of the southern San Andreas Fault from 10Be-26Al surface exposure dating of an offset alluvial fan by Ryerson, Frederick J., Van der Woerd, Jérôme, Klinger, Yann, Sieh, Kerry, Tapponnier, Paul, Mériaux, Anne-Sophie

“…Field mapping complemented with topographic data, air photos and satellite images allows precise determination of piercing points across the fault zone that are used to measure an offset of 565 ± 80 m. …”

Locomotion study and improvement of multi-legged robots involving CG adjustment by Chen, Wenjie.

“…However, these demanding specifications are not always compatible when legged robots walk on terrain containing a lot of forbidden zones. This thesis is aimed to present and investigate the CG (Center of Gravity) adjustment methods, and provide strategies to improve legged machines' comprehensive (static and dynamic) locomotion behaviors on rough terrain.…”

Modeling pedestrian activity in cities with urban network analysis by Sevtsuk, Andres, Kalvo, Raul

“…Car-centered travel demand models and land-use-transportation interaction models have historically analyzed zone-to-zone trips along major roadways, largely omitting pedestrian and bicycle trips and creating a gap in the ability for planners and urban designers to systematically assess non-motorized outcomes of development interventions. …”

Dynamic lateral crushing of empty and sandwich tubes by Fan, Zhihua., Shen, Jianhu., Lu, Guoxing., Ruan, Dong.

“…The propagation of plastic bending in the form of double-moving-hinges is the main mechanism of energy dissipation, as opposed to the low velocity impact which involves stationary plastic deformation zones.…”

Assisted child-minding based on visual activity monitoring in a home camera surveillance system by Wu, Jason Weixiang.

“…Firstly, the proposed system will require the user to identify the estimated location of the child and define a danger zone of which the child may endanger himself if he should come into contact with. …”

Transmission-scanning electron microscopy of interface fracture of ferrite deformation twins by Koko, A, Marrow, TJ

“…This provided details of the lattice misorientation and dislocation arrangement, including the dislocation-free zone at the twin tip. These observations provide evidence for the link between microcracking of the irregular twin/parent interface and relaxation of the residual strains that arise from twin growth, offering new insights into fracture mechanics in these materials.…”

Different icosahedra in metallic glasses : stability and response to shear transformation by Wang, Chang Chun., Wong, C. H.

“…Newly created icosahedra during the deformation process are as prone as non-icosahedral atoms with low-population polyhedra to the formation of shear transformation zones (STZs). Interconnected networks have been proven to play a critical role on their response to shear strain. …”

Experimental investigation on the effect of masked multiple passes abrasive waterjet machining surface texturing on coefficient of friction by Hafiz, Husin, Mohd Nazir, Mat Nawi, Asmelash, Mebrahitom Asmelash, Kushendarsyah, Saptaji, Azmir, Azhari

“…Laser surface texturing is the popular choice; however, this method suffers drawbacks such as cracking, heat-affected zone, and generation of hazardous fumes. The Abrasive Water Jet Machining (AWJM) was chosen is that, because the eroded material is carried by the waterjet, the process is clean and does not produce dust, chips, or chemical contaminants. …”

Rectified and Salt Concentration Dependent Wetting of Hydrophobic Nanopores by Polster, Jake W, Aydin, Fikret, de Souza, J Pedro, Bazant, Martin Z, Pham, Tuan Anh, Siwy, Zuzanna S

“…The nanopore we study contains a junction between a hydrophobic zone and a positively charged hydrophilic zone. The nanopore is closed for transport at low salt concentrations and exhibits finite current only when the concentration reaches a threshold value that is dependent on the pore opening diameter, voltage polarity and magnitude, and type of electrolyte. …”

A modified Prandtl-Ishlinskii hysteresis model for modeling and compensating asymmetric hysteresis of piezo-actuated flexure-based systems by Zhou, Chao, Yuan, Meng, Feng, Chen, Ang, Wei Tech

“…Conventional models were presented to model this undesired effect using additional dead-zone operators. This paper presents a new approach using two sets of operators with a distributed compensator to model and compensate for the asymmetric system hysteresis based on inversion calculation with a simplified digitized representation. …”
