Efecto de las impurezas en las propiedades físicoquímicas de una solución de lixiviación de minerales de cobre
Authors: Navarro Patricio , Vargas Cristián , Ramírez Carlos 
Published: April 2016

Se cuantificaron y analizaron las propiedades físicas y químicas de una solución de lixiviación de minerales de cobre con una elevada concentración de cloro, aluminio y magnesio. Las propiedades analizadas fueron densidad, viscosidad y oxígeno disuelto. También se evaluó el efecto de la viscosidad sobre el tiempo de separación de fases en extracción por solvente. Las concentraciones utilizadas de cloro fueron 20, 30 y 50 g/L, las de aluminio, 7, 15 y 23 g/L, y las de magnesio, de 6, 14 y 22 g/L. Las temperaturas ensayadas fueron 25, 35 y 45 °C. Los resultados obtenidos muestran que la presencia de impurezas produce un importante impacto en la viscosidad de la solución y solamente pequeños cambios en la densidad. El elemento que menos impacta en estas propiedades es el cloro, seguido del magnesio, y el que produjo mayor cambio fue el aluminio. El aumento de temperatura reduce el impacto de estos elementos. La presencia de impurezas disminuye la concentración de oxígeno disuelto. En extracción por solventes, un aumento en la viscosidad provoca tiempos más prolongados en la separación de fases.

Special Issue on Precise Positioning
Authors: Noritsugu Toshiro 
Published: April 2016

Precise positioning is a basic, essential technology in a wide variety of automation considerations. It has recently been extended to micron and nanometer positioning including basic components such as mechanical elements, mechanisms, actuators, and controllers. Improving positioning accuracy requires advances in individual components, behind which there has been conducted much research and development.
This special issue focuses on actuator, control technology, and mechanical elements and mechanisms. Constructing precise positioning involves conventional electrical, hydraulic, and pneumatic actuators. A piezoelectric actuator is useful for micron and nanometer positioning. An appropriate mechanism is required to transmit power from the actuator to the object being positioned. An effective control scheme must also be introduced into system with available sensors.
In this regard, this issue includes advanced papers representative of individual fields that should prove interesting, stimulating, and of great practical use to both general readers and specialists.

Simulators play important roles in the designing of new acturing systems. As manufacturing systems are being created on larger and more complicated scales than ever before, it is increasingly necessary to have opportunities for several persons to design a manufacturing system concurrently. In this case, the designers often use suitable discrete event simulators to evaluate their assigned subsystems. After the subsystems are evaluated, it is necessary to evaluate the full system. To do this, the designers need to make the manufacturing system model by synchronizing several different simulators. In such distributed simulation systems using discrete event simulators, it is important to manage a distributed simulation clock and each simulator clock as well as to define interfaces among the simulation models. With the simulation clock, it is often necessary to perform rollbacks. The rollback function returns the simulation clock to a past time in order to synchronize events among the simulations. However, most commercially available simulators do not include the rollback function.The purpose of this research is to develop a distributed simulation synchronization method that includes a function for managing distributed simulation clocks without the rollback function and for managing interfaces among simulation models.In this paper, we propose a storage model concept as the method. We develop an algorithm to implement the proposed concept, and we develop a distributed simulation system configuration using HLA. A case study is then carried out to evaluate the performance of the cooperative work.

Special Issue on Texturing Processes and Attainable Functionalities
Authors: Moronuki Nobuyuki 
Published: April 2016

Regular micro/nanostructures or textures provide such functions as optical or friction properties, but neither texture design nor the texturing process has been well developed. Functional texture is often inspired by natural designs, with the microstructure on the surface of lotus leaves or the nanostructure on the bottoms of geckos’ feet often cited as examples. “Biomimetic” has become a keyword in state-of-the-art technologies. Processes are also important because functional textures require a wide range of structural dimensions, from nanometers to micrometers. Top-down processes such as cutting or energy beam processing are often used and are based on the copying principle. Bottom-up processes include the self-assembly of particles and the anodic oxidation of aluminum. As the principle behind bottom-up processes is completely different from that behind top-down processes, special attention is warranted. Furthermore, material deposition can effect drastic changes in surface functionality. This special issue features nine papers, including eight studies and one review paper, classified into the following topics:
- Biomimetic design of functions
- Top-down or cutting texturing processes
- Bottom-up or self-organization texturing processes
- Measurement system for textures
- Optical applications
- Optical applications
- Adhesive applications
- Biomedical applications
These papers present the latest advances in texturing processes, functional design, and realization or demonstration. Learning more about these advances will enable readers toshare their knowledge and experience in technologies, development, and potential texturing applications. In closing, I would like to express my sincere gratitude to the authors and reviewers for their interesting and enlightening contributions to this special issue.

The proposed method also uses optimization operators designed for this problem and quality evaluation to maintain natural, smooth movement.

This work is a first step towards an integration ofmultimodality with the aim to make efficient use of both human-like, and non-human-like feedback modalities in order to optimize proactive information retrieval from task-related Human-Robot Interaction (HRI) in human environments. The presented approach combines the human-like modalities speech and emotional facial mimicry with non-human-like modalities. The proposed non-human-like modalities are a screen displaying retrieved knowledge of the robot to the human and a pointer mounted above the robot head for pointing directions and referring to objects in shared visual space as an equivalent for arm and hand gestures. Initially, pre-interaction feedback is explored in an experiment investigating different approach behaviors in order to find socially acceptable trajectories to increase the success of interactions and thus efficiency of information retrieval. Secondly, pre-evaluated humanlike modalities are introduced. First results of a multimodal feedback study are presented in the context of the IURO project,1where a robot asks for its way to a predefined goal location.1.

This paper proposes YURAGI synthesis for brain imaging under the skull. The advantage of the proposed method over conventional methods is that, using YURAGI synthesis, it is possible to obtain the effective results without image registration. Image registration is generally needed when more than two images are to be synthesized into one image. YURAGI synthesis does not need image registration; thus, its method is simpler than other methods that need image synthesis. The effectiveness of the proposed method was confirmed by comparing its error rate and accuracy with those of other methods. YURAGI leads the simple and energy-saving system with performing autoregulation. Autoregulation is utilized in many biological systems. In this study, YURAGI was applied to an ultrasound-based diagnostic medical imaging technique. The experimental results using YURAGI were superior to those using othermethods. Thus, YURAGI is useful for visualizing the human brain.11. This paper has been reviewed and accepted as a regular paper. The paper was invited and incorporated into the Special Issue on Advances in Fuzzy Inference and its Related Techniques.
Special Issue on Extinction of Organisms
Authors: Higuchi Hiroyoshi , Karaki Hideaki 
Published: April 2016

Plants and animals are declining or becoming extinct in many parts of the world. They include both well-known species such as the giant panda (Ailuropoda melanoleuca) and the crested ibis (Nipponia nippon) and once common land snails, fireflies and small migratory birds. Factors leading to population decline or extinction include habitat destruction, chemical pollution, alien species, poaching, infectious disease, and global warming. In addition to their individual adverse impacts, these factors often overlap or interconnect in time and space, compounding their effects. In limited areas isolated by habitat destruction, for example, alien species and global warming more easily cause local populations to decline and become extinct.
There are also natural disasters such as volcanic activity and meteors that diminish or exterminate flora and fauna populations. However, extinction of species and groups sometimes give an opportunity for other species and groups to occupy vacant niche and similar life styles, which may lead to adaptive radiation in evolution. Organisms have repeated such evolution and extinction throughout geological history.
This special issue focuses on the extinction of plants and animals resulting from both human activity and natural disasters. In the first of seven articles, Hisashi Nagata reviews the history of extinction and the natural and human factors involved. Kazuto Kawakami looks at the impact of alien species on current ecosystems in the Ogasawara Islands, demonstrating interrelationships among different plant and animal species and pointing out what we could do about island ecosystem conservation and management. Haruo Ogi discusses the effects of fisheries by-catch on sea birds. TatsuyaKunisue and Shinsuke Tanabe detail the effects of chemical pollution on wild animals. Both factors are important in conserving biodiversity and in maintaining industries such as marine fisheries. Kazuya Ashizawa et al. focus on the population decline and extinction of plants growing along dry river beds and becoming rare as a result of human activities changing the structure of natural rivers. Yunshan Su deals with the history of the near extinction of crested ibises in China, and introduces successful recovery programs that may be useful in a similar Japanese program for the same species. Takashi Kamijo et al. detail the impact of volcanic activity on the vegetation of a small island, discussing ecosystem recovery.
We hope that this special issue will lead to better understanding of the unique interrelationships among plants, animals and the inorganic world, teaching how to conserve and manage the biodiversity around us. Extinction of one species may appear to have nothing to do with human lives, but the extinction of many plants and animals sets up serious conditions in maintaining life during the changing structure and function of ecosystems comparable in process to an aircraft losing rivets one by one and finally crashing at a critical point with massive loss of life.
