Pass Through

To improve the service quality of service robots for the disabled, immune system is applied on robot for its advantages such as diversity, dynamic, parallel management, self-organization, and self-adaptation. According to the immune system theory, local environment condition sensed by robot is considered an antigen while robot is regarded as B-cell and possible node as antibody, respectively. Antibody-antigen affinity is employed to choose the optimal possible node to ensure the service robot can pass through the optimal path. The paper details the immune system applications on service robot and gives experimental results.

Sensor Information

Service robot is currently gaining traction, particularly in hospitality, geriatric care and healthcare industries. The navigation of service robots requires high adaptability, flexibility and reliability. Hence, map-based navigation is suitable for service robot because of the ease in updating changes in environment and the flexibility in determining a new optimal path. For map-based navigation to be robust, an accurate and precise localization method is necessary. Localization problem can be defined as recognizing the robot’s own position in a given environment and is a crucial step in any navigational process. Major difficulties of localization include dynamic changes of the real world, uncertainties and limited sensor information. This paper presents a comparative review of sensor technology and sensor fusion methods suitable for map-based localization, focusing on service robot applications.

AbstractThe use of service robots to assist ageing people in their own homes has the potential to allow people to maintain their independence, increasing their health and quality of life. In many assistive applications, robots perform tasks on people’s behalf that they are unable or unwilling to monitor directly. It is important that users be given useful and appropriate information about task progress. People being assisted in homes and other realworld environments are likely be engaged in other activities while they wait for a service, so information should also be presented in an appropriate, nonintrusive manner. This paper presents a human-robot interaction experiment investigatingwhat type of feedback people prefer in verbal updates by a service robot about distributed assistive services. People found feedback about time until task completion more useful than feedback about events in task progress or no feedback. We also discuss future research directions that involve giving non-expert users more input into the task planning process when delays or failures occur that necessitate replanning or modifying goals.

Indoor Monitoring

To move out of the lab, service robots must reveal a proven robustness so they can be deployed in operational environments. This means that they should function steadily for long periods of time in real-world areas under uncertainty, without any human intervention, and exhibiting a mature technology readiness level. In this work, we describe an incremental methodology for the implementation of an innovative service robot, entirely developed from the outset, to monitor large indoor areas shared by humans and other obstacles. Focusing especially on the reliability of the fundamental localization system of the robot in the long term, we discuss all the incremental software and hardware features, design choices, and adjustments conducted, and show their impact on the performance of the robot in the real world, in three distinct 24-h long trials, with the ultimate goal of validating the proposed mobile robot solution for indoor monitoring.

First Report

Most underground ecosystems are heterotrophic, fungi in these objects are dispersed in the air in the form of spores, and they may be potentially hazardous to mammals. Research in underground sites has focused on mesophilic airborne fungi and only a few concerned cold-adapted species. Therefore, the goal of our research was the first report of psychrophilic and psychrotolerant aeromycota in the Brestovská Cave using culture-based techniques with genetic and phenotypic identification. Plates with PDA medium containing sampled biological material were incubated at 8 ± 0.5 °C. The density of mycobiota inside the cave ranged from 37.4 to 71 CFU 1 m−3 of air and 63.3 CFU 1 m−3 of air outside the cave. Thus, the level of fungal spores did not exceed the standards for the mycological quality of the air. A total of 18 species were isolated during the study, and some species may be potentially dangerous to people with weakened immune system. All fungal species were present inside the cave and only seven of them were outside. Cladosporium cladosporioides dominated in the external air samples and Mortierella parvispora was cultured most frequently from internal air samples. To our knowledge, this is the first discovery of the fungal species such as Coniothyrium pyrinum, Cystobasidium laryngis, Filobasidium wieringae, Leucosporidium drummii, M. parvispora, Mrakia blollopis, Nakazawaea holstii, and Vishniacozyma victoriae in the air inside the underground sites. Moreover, C. pyrinum, C. laryngis, L. drummii, M. blollopis, and N. holstii have never been detected in any component of the underground ecosystems. There are possible reasons explaining the detection of those species, but global warming is the most likely.

Patients Perspective

Abstract The speaker will present the perspective of the cancer patients, and the challenges they encounter across the spectrum of care and what measures they consider relevant in terms of prevention, diagnosis, treatment and, indeed, to raise awareness of the impact of AMR on rendering cancer treatments ineffective. She will elaborate on survivorship, and on the impact of AMR on the quality of life of patients, their carers, and families. Emphasis will be given on the implications of modern therapies, such as immunotherapy, representing a unique challenge in terms of better understanding the effect on overall health of patients, with the effect they have the immune system, further weakening the patient and leaving him/her exposed to infections potentially of higher risk than cancer itself.

The immune genetic algorithm is a kind of heuristic algorithm which simulates the biological immune system and introduces the genetic operator to its immune operator. Conquering the inherent defects of genetic algorithm that the convergence direction can not be easily controlled so as to result in the prematureness；it is characterized by a better global search and memory ability. The basic principles and solving steps of the immune genetic algorithm are briefly introduced in this paper. The immune genetic algorithm is applied to the survey data processing and experimental results show that this method can be practicably and effectively applied to the survey data processing.

The Impact

Purpose This study aims to examine humans’ reactions to service robots’ display of warmth in robot-to-robot interactions – a setting in which humans’ impressions of a service robot will not only be based on what this robot does in relation to humans, but also on what it does to other robots. Design/methodology/approach Service robot display of warmth was manipulated in an experimental setting in such a way that a service robot A expressed low versus high levels of warmth in relation to another service robot B. Findings The results indicate that a high level of warmth expressed by robot A vis-à-vis robot B boosted humans’ overall evaluations of A, and that this influence was mediated by the perceived humanness and the perceived happiness of A. Originality/value Numerous studies have examined humans’ reactions when they interact with a service robot or other synthetic agents that provide service. Future service encounters, however, will comprise also multi-robot systems, which means that there will be many opportunities for humans to be exposed to robot-to-robot interactions. Yet, this setting has hitherto rarely been examined in the service literature.

The Disabled

The relationships between siblings are the most long-lasting in families. When one of the siblings is a person with intellectual disabilities (ID), this relationship assumes an even more important role since this brother/sister will most likely become the disabled individual’s main caregiver. This pilot study had two aims: to explore the experience as an adolescent or adult sibling of a person with ID and to understand the perceptions of these siblings about quality of life as a sibling and about family quality of life. In-depth interviews were conducted with six siblings. The results showed that the experience of a sibling is positive and the acceptance process is of extreme importance. The domains which, from the sibling perspective, contribute to family quality of life are as follows: Family relationships, Acceptance, Health, Influence of values, Financial well-being, Support from others, and Leisure activities. The implications of these findings for intervention are pointed out.

Abstract We will describe an FPGA implementation of PID-controller that uses differential evolution to optimize the coefficients of the PID controller, which has been implemented in VHDL. The original differential evolution algorithm was improved by ranking based mutation operation and self-adaptation of mutation and crossover parameters. Ranking-based mutation operation improves the quality of solution, convergence rate and success of optimization. Due to the self-adaptive control parameters, the user does not have to estimate the mutation and crossover rates. Optimization have been performed by calculating for each generation fitness value by means of trial parameters. The final optimal parameters are selected based on the minimum fitness.

Radical Ideas

Utilitarianism has a curious history. Its most celebrated founders—Jeremy Bentham and John Stuart Mill—were radical progressives, straddling the worlds of academic philosophy, political science, economic theory and practical affairs. They made innumerable recommendations for legal, social, political and economic reform, often (especially in Bentham's case) described in fine detail. Some of these recommendations were followed, sooner or later, and many of their radical ideas have become close to articles of faith of western liberalism. Furthermore many of these recommendations were made expressly to improve the condition of the deprived, or of oppressed groups. Yet the moral theory which inspired this reforming zeal is, at least officially, utilitarianism, and when we teach this theory to our students we feel it our duty to point out the horrors that could be justified by any theory which assesses the moral quality of actions in terms of the maximization of good consequences over bad. No consequence is so bad that it cannot, in principle, be outweighed by a large aggregation of smaller goods. Hence there are circumstances in which utilitarianism can require slavery, the punishment of the innocent, and redistribution of resources from the poor to the rich, or from the disabled and the sick to the able bodied and healthy. Indeed, in the right circumstances, it can justify pretty much anything you can think of. For all their intelligence and imagination neither Bentham nor Mill seemed to recognise or discuss these catastrophic possibilities.
