Paper Session III-B - A Roadmap for Space Microelectronics Technology into the New Millennium
Advances in microelectronics technologies over the past several decades have truly revolutionized modern society in almost every aspect of human endeavor. The continuous scaling of the commercial semiconductor technology to smaller and smaller device and interconnect feature sizes (referred to as MooreĂs Law due to Gordon Moore of Intel) has lead to more and more functionality being developed onto a single silicon Ă«chipĂ. Moreover, the manufacturing cost of an on-chip function is getting cheaper and cheaper. These two factors: Ă«more for lessĂ represents the fuel that has propelled the microelectronics technology revolution of the 20th century. How long will this technology revolution last into the new millennium is a key question that the semiconductor industry is continuously evaluating. An excellent roadmap of the commercial semiconductor technology needs for the next 15 years (from 1997 to 2012) is described in The National Technology Roadmap for Semiconductors, published by the Semiconductor Industry Association (SIA) in December 1997 [1]
Localization in Unstructured Environments: Towards Autonomous Robots in Forests with Delaunay Triangulation
Autonomous harvesting and transportation is a long-term goal of the forest
industry. One of the main challenges is the accurate localization of both
vehicles and trees in a forest. Forests are unstructured environments where it
is difficult to find a group of significant landmarks for current fast
feature-based place recognition algorithms. This paper proposes a novel
approach where local observations are matched to a general tree map using the
Delaunay triangularization as the representation format. Instead of point cloud
based matching methods, we utilize a topology-based method. First, tree trunk
positions are registered at a prior run done by a forest harvester. Second, the
resulting map is Delaunay triangularized. Third, a local submap of the
autonomous robot is registered, triangularized and matched using triangular
similarity maximization to estimate the position of the robot. We test our
method on a dataset accumulated from a forestry site at Lieksa, Finland. A
total length of 2100\,m of harvester path was recorded by an industrial
harvester with a 3D laser scanner and a geolocation unit fixed to the frame.
Our experiments show a 12\,cm s.t.d. in the location accuracy and with
real-time data processing for speeds not exceeding 0.5\,m/s. The accuracy and
speed limit is realistic during forest operations
Embodied Evolution in Collective Robotics: A Review
This paper provides an overview of evolutionary robotics techniques applied
to on-line distributed evolution for robot collectives -- namely, embodied
evolution. It provides a definition of embodied evolution as well as a thorough
description of the underlying concepts and mechanisms. The paper also presents
a comprehensive summary of research published in the field since its inception
(1999-2017), providing various perspectives to identify the major trends. In
particular, we identify a shift from considering embodied evolution as a
parallel search method within small robot collectives (fewer than 10 robots) to
embodied evolution as an on-line distributed learning method for designing
collective behaviours in swarm-like collectives. The paper concludes with a
discussion of applications and open questions, providing a milestone for past
and an inspiration for future research.Comment: 23 pages, 1 figure, 1 tabl
RoboCup 2D Soccer Simulation League: Evaluation Challenges
We summarise the results of RoboCup 2D Soccer Simulation League in 2016
(Leipzig), including the main competition and the evaluation round. The
evaluation round held in Leipzig confirmed the strength of RoboCup-2015
champion (WrightEagle, i.e. WE2015) in the League, with only eventual finalists
of 2016 competition capable of defeating WE2015. An extended, post-Leipzig,
round-robin tournament which included the top 8 teams of 2016, as well as
WE2015, with over 1000 games played for each pair, placed WE2015 third behind
the champion team (Gliders2016) and the runner-up (HELIOS2016). This
establishes WE2015 as a stable benchmark for the 2D Simulation League. We then
contrast two ranking methods and suggest two options for future evaluation
challenges. The first one, "The Champions Simulation League", is proposed to
include 6 previous champions, directly competing against each other in a
round-robin tournament, with the view to systematically trace the advancements
in the League. The second proposal, "The Global Challenge", is aimed to
increase the realism of the environmental conditions during the simulated
games, by simulating specific features of different participating countries.Comment: 12 pages, RoboCup-2017, Nagoya, Japan, July 201
The New Economy- Knowledge Based Economy
The aim of this paper is to emphasize the importance of knowledge based economy, in this time characterized by fast changes and sometimes radical changes, it is impossible to resist without adapting, both people and the organizations too. The matter of the paper develops knowledge based economy concept: elements, definitions of the knowledge based economy, stages and the main knowledge codification. In the end of the paper, the author presents the importance of economy knowledge, in Romanian organizations.knowledge based economy, knowledge society, knowledge based organization, longlife learning, learning organization
Bioethics: Reincarnation of Natural Philosophy in Modern Science
The theory of evolution of complex and comprising of human systems and algorithm for its
constructing are the synthesis of evolutionary epistemology, philosophical anthropology and
concrete scientific empirical basis in modern (transdisciplinary) science. «Trans-disciplinary» in
the context is interpreted as a completely new epistemological situation, which is fraught with the
initiation of a civilizational crisis. Philosophy and ideology of technogenic civilization is based on
the possibility of unambiguous demarcation of public value and descriptive scientific discourses
(1), and the object and subject of the cognitive process (2). Both of these attributes are no longer
valid. For mass, everyday consciousness and institutional philosophical tradition it is intuitively
obvious that having the ability to control the evolutionary process, Homo sapiens came close to the
borders of their own biological and cultural identity. The spontaneous coevolutionary process of
interaction between the «subject» (rational living organisms) and the «object» (material world), is
the teleological trend of the movement towards the complete rationalization of the World as It Is,
its merger with the World of Due. The stratification of the global evolutionary process into selective
and semantic (teleological) coevolutionary and therefore ontologically inseparable components
follows. With the entry of anthropogenic civilization into the stage of the information society, firsty,
the post-academic phase of the historical evolution of scientific rationality began, the attributes of
which are the specific methodology of scientific knowledge, scientific ethos and ontology. Bioethics
as a phenomenon of intellectual culture represents a natural philosophical core of modern post-
academic (human-dimensional) science, in which the ethical neutrality of scientific theory
principle is inapplicable, and elements of public-axiological and scientific-descriptive discourses
are integrated into a single logic construction. As result, hermeneutics precedes epistemology not
only methodologically, but also meaningfully, and natural philosophy is regaining the status of the
backbone of the theory of evolution – in an explicit for
