This paper presents a novel approach for guiding mobile robots inside greenhouses demonstrated by promising preliminary physical experiments. It represents a comprehensive attempt to use the successful principles of AGVs (auto-guided vehicles) inside greenhouses, but avoiding the necessity of modifying the crop layout, and avoiding having to bury metallic pipes in the greenhouse floor. The desi...

springback is one of the most common and important issues in metal forming area. due to it depends on variety of parameters, it is hard to predict. hence, in this paper, the effect of continuum damage mechanics (cdm) based on the lemaitre isotropic unified damage lawon springback was investigated. swift’s hardening law was employed to describe isotropic hardening behavior.the result showed cons...

This review analyzes an interdisciplinary approach to the pancreatic endocrine network-like relationships that control glucagon secretion and glucagon counterregulation (GCR). Using in silico studies, we show that a pancreatic feedback network that brings together several explicit interactions between islet peptides and blood glucose reproduces the normal GCR axis and explains its impairment in...

Backgroud: This study was to validate the feasibility of using clinical 3.0T MRI to monitor the migration of autotransplanted bone marrow (BM)-derived stem-progenitor cells (SPC) to the injured arteries of near-human sized swine for potential cell-based arterial repair. Methodology: The study was divided into two phases. For in vitro evaluation, BM cells were extracted from the iliac crests of ...

This paper presents the generalized results of analysisand synthesis scientific and technical sources investigation heavy concrete on basis fracture mechanics for last 25-30 years.New criteria models concrete, which were obtained during this period have been described generalized, in particular, a new deformation model crack resistance mechanics. The analysis experimental theoretical researches...

While liking or upvoting a post on a mobile app is easy to do, replying with a written note is much more difficult, due to both the cognitive load of coming up with a meaningful response as well as the mechanics of entering the text. Here we present a novel textual reply generation model that goes beyond the current auto-reply and predictive text entry models by taking into account the content ...

Introduction Analysis of the forced nonlinear dynamical systems plays an important role for understanding of the various noise-induced phenomena in mechanics, electronics, biology and economics. Even small random disturbances may essentially change behavior of the dynamic system and generate noise-induced transitions, stochastic bifurcations, noise-induced order and chaos [1-7]. In the present ...

Modeling the evolution of a financial index as a stochastic process is a problem awaiting a full, satisfactory solution since it was first formulated by Bachelier in 1900. Here it is shown that the scaling with time of the return probability density function sampled from the historical series suggests a successful model. The resulting stochastic process is a heteroskedastic, non-Markovian marti...

This paper investigates the lateral vibration of single-layered graphene sheets based on a new theory called doublet mechanics with a length scale parameter. After a brief reviewing of doublet mechanics fundamentals, a sixth order partial differential equation that governs the lateral vibration of single-layered graphene sheets is derived. Using doublet mechanics, the relation between natural f...
