Synergy of robotics and ICT in the smart farming
There are many concept and technology to robotize in agriculture. The robotization has an intensive synergy with artificial intelligence (AI), information and communication technology (ICT) and sensor technology (ST). These technologies drive into the 4th revolution industry. The industrial processes help the automatization in agriculture. The demand for food products are growing, the working force getting old, these impacts forces the robot applications. This article introduce the robots in the agriculture, and the Szent István University current research on the fields
Note on (conformally) semi-symmetric spacetimes
We provide a simple proof that conformally semi-symmetric spacetimes are
actually semi-symmetric. We also present a complete refined classification of
the semi-symmetric spacetimes.Comment: 5 pages, no figure
Operator’s behaviour measuring methodology inside off-road vehicle cabin, operator’s focusing scheme
ArticleOperator’s workplace design takes a priority to be developed in order to reach the
highest possible level of Quality, Safety and productivity. Continual improvement of the
workplace is yield from studies carried out on different approaches, each approach shall keep into
consideration many aspects, in this research; the results will be used for feeding the productivity
aspects with valuable and reliable input data using relatively simple engineering solutions. This
research is made based on literature of the accumulated knowledge from diverse fields in which
different studies and analysis are made to provide the necessary input for Human Centred Design
process, adopting the-state-of-the-art technologies and methodologies used for data collection
and analysis for Human behaviour inside the dedicated workplace. Better understanding of the
operator’s Gaze in addition to the change according to the mental and physical workloads inside
the tractor cabin will lead to optimal designs for higher productivity operation
Modelling of operator’s focusing scheme along working hours: harvesting operation
ArticleIn consistent with the growing research activities regarding the Farm 4.0 concept, it is
valuable to consider each possible chance of enhancement which is expected to contribute
positively to the productivity and the safety of planned operations. Human centred design concept
is becoming essential for the multitasking vehicles market, which promotes the research
experiments aiming to understand the human behaviour inside the vehicle cabins to proceed with
upgrading the design, planning and production procedures based on validated inputs leading to
introducing reliable solutions for more productive and safety conduct of operations. The accurate
and deep analysis of the operator behaviour inside the cabin will lead to a better understanding
for the problems and issues need to be resolved in new designs in addition to providing the
production planning (i.e. manpower planning and working shift period) with the necessary data
to ensure achieving the maximum efficiency and effectiveness. In this research, the operator’s
glance behaviour inside the tractor cabin is studied during the harvesting operation to develop a
model for the change of operator's focusing scheme along working hours
Investigation of all Ricci semi-symmetric and all conformally semi-symmetric spacetimes
We find all Ricci semi-symmetric as well as all conformally semi-symmetric
spacetimes. Neither of these properties implies the other. We verify that only
conformally flat spacetimes can be Ricci semi-symmetric without being
conformally semi-symmetric and show that only vacuum spacetimes and spacetimes
with just a -term can be Ricci semi-symmetric without being
conformally semi-symmetric.Comment: 4 pages, 1 tabl
Topology with Dynamical Overlap Fermions
We perform dynamical QCD simulations with overlap fermions by hybrid
Monte-Carlo method on to lattices. We study the problem of
topological sector changing. A new method is proposed which works without
topological sector changes. We use this new method to determine the topological
susceptibility at various quark masses.Comment: 15 pages, 3 figure
The clustering of gamma-ray bursts in the Hercules-Corona Borealis Great Wall: the largest structure in the Universe?
The Hercules-Corona Borealis Great Wall is a statistically significant
clustering of gamma-ray bursts around redshift 2. Motivated by recent
theoretical results indicating that a maximal Universal structure size may
indeed coincide with its estimated size (2-3Gpc), we reexamine the question of
this Great Wall's existence from both observational and theoretical
perspectives. Our statistical analyses confirm the clustering's presence in the
most reliable data set currently available, and we present a video showing what
this data set looks like in~3D. Cosmological explanations (i.e. having to do
with the distribution of gravitating matter) and astrophysical explanations
(i.e. having to do with the rate of star formation over cosmic time and space)
regarding the origin of such a structure are presented and briefly discussed
and the role of observational bias is also discussed at length. This, together
with the scientific importance of using gamma-ray bursts as unique cosmological
probes, emphasises the need for future missions such as the THESEUS satellite
which will provide us with unprecedentedly homogeneous data of gamma-ray bursts
with measured redshifts. We conclude from all this that the Hercules-Corona
Borealis Great Wall may indeed be the largest structure in the Universe - but
to be able to decide conclusively whether it actually exists, we need THESEUS.Comment: Accepted for publication in MNRAS. 12 pages, 3 figures, 3 table
