http://dx.doi.org/10.1016/j.anbehav.2014.09.008 0003-3472/© 2014 The Association for the Study of A Among the many hand preference studies on nonhuman primates, several have demonstrated the effect of diverse action demands on the direction and magnitude of hand preference. However, few studies have assessed hand preference in the natural repertoire of motor behaviours in nonhuman primates, esp...

The rapid, stable, and undamaged picking of small-sized spherical fruits are one the key technologies to improve level intelligent robots reduce grading operations. Cherry tomatoes were selected as research object in this work. Picking strategies two-stage “Holding-Rotating” finger-end grasping determined. end-effector was designed separate fruit from stalk based on linear motion constraint par...

The poor adaptability of existing harvesting machinery and low work efficiency is observed due to the low-level mechanized Xinjiang jujube orchards. A mechanical floor-standing picker was designed on basis characteristics high fruit drop harvest period. machine can pick up jujubes, which have been manually collected into strips ground. structure working parameters pickup device are determined i...

Vowels, consonants, and sentences were processed by two cochlear-implant signal-processing strategies-a fixed-channel strategy and a channel-picking strategy-and the resulting signals were presented to listeners with normal hearing for identification. At issue was the number of channels of stimulation needed in each strategy to achieve an equivalent level of speech recognition in quiet and in n...

Fruit detection is crucial for yield estimation and fruit picking system performance. Many state-of-the-art methods use convolutional neural networks (CNNs). This paper presents the results peach by applying a faster R-CNN framework in images captured from an outdoor orchard. Although this method has been used other studies to detect fruits, there no research on peaches. Since colors, sizes, sh...

the shear strength and shear energy per unit area, as well as the force and energy required for picking flowers, are important parameters in the design and development of harvesting mechanisms. in this study, shear strength and shear energy per unit area of saffron (crocus sativus l.) stems were determined at different bevel angles and shear velocities. the force and energy required for picking...

Recently, the minimum number of reticulation events that is required to simultaneously embed a collection P of rooted binary phylogenetic trees into a so-called temporal network has been characterized in terms of cherry-picking sequences. Such a sequence is a particular ordering on the leaves of the trees in P. However, it is well-known that not all collections of phylogenetic trees have a cher...

The objective of this study is to determine the efficacy of the bait spray applications in controlling of fruit flies (Diptera: Tephritidae) on fruits and vegetables under field conditions and to make recommendations on how to move this package forward to all stakeholders. Because of concerns over damage to the environment and human health by insecticide cover sprays for fruit fly control, the ...
