Abstract:

Software agents represent a radical departure from earlier monolithic approaches to artificial intelligence by introducing intelligence in small packages in many different places. For each instance of potential aiding there are two questions: 1- can a software agent perform the task? and 2- can the agent's assistance contribute to team performance? Our research addresses these two issues by demonstrating the feasibility of sophisticated agent assistance in scenario-based technology demonstrations and investigating the contribution of agent assistance to human team performance using simplified, controllable laboratory experiments.

Abstract:

Abstract. After the incidence of a disaster, a high demand for first-aid and a huge number of injured will emerge at the affected areas. In this paper, the optimum allocation of the medical assistance to the injured according to a multi-criteria decision making is performed by Multiplicatively Weighted Network Voronoi Diagram (MWNVD). For consideration of the allocation of the injured in the affected area to the appropriate hospitals using the MWNVD and decreasing the gap between the estimated and expected population in the MWNVDs, Particle Swarm Optimization (PSO) is applied to the MWNVDs. This paper proposes a multi agent-based modeling for incorporating the allocation of the medical supplies to the injured according to the generated Voronoi Diagrams of the PSO-MWNVD, wayfinding of emergency vehicles based on the minimum travel distance and time as well as using smart city facilities to expedite the rescue operation. In the proposed model, considering the priority of the injured for receiving the medical assistance, information transfer about the condition of the injured to the hospitals prior to ambulance arrival for providing appropriate treatment, updating of emergency vehicles route based on the blocked streets and etc. are optimized. The partial difference between the estimated and expected population for receiving the medical assistance in MWNVDs is computed as 37&thinsp;%, while the PSO-MWNVD decreased the mentioned difference to 6&thinsp;%. The relief operation time in the proposed model compared to another multi-agent rescue operation model, which uses MWNVD and does not have some facilities of the proposed model, is improved.

Abstract:

Through the application of intelligent systems in driver assistance systems, the experience of traveling by road has become much more comfortable and safe. In this sense, this paper then reports the development of an intelligent driving assistant, based on vehicle telemetry and road accident risk map analysis, whose responsibility is to alert the driver in order to avoid risky situations that may cause traffic accidents. In performance evaluations using real cars in a real environment, the on-board intelligent assistant reproduced real-time audio-visual alerts according to information obtained from both telemetry and road accident risk map analysis. As a result, an intelligent assistance agent based on fuzzy reasoning was obtained, which supported the driver correctly in real-time according to the telemetry data, the vehicle environment and the principles of secure driving practices and transportation regulation laws. Experimental results and conclusions emphasizing the advantages of the proposed intelligent driving assistant in the improvement of the driving task are presented.

Abstract:

Even though biomass is characterised as renewable energy, it produces anthropogenic greenhouse gas (GHG) emissions, especially from biomass logistics. Lifecycle assessment (LCA) is used as a tool to quantify the GHG emissions from logistics but in the past the majority of LCAs have been steady-state and linear, when in reality, non-linear and temporal aspects (such as weather conditions, seasonal biomass demand, storage capacity, etc.) also have an important role to play. Thus, the objective of this paper was to optimise the environmental sustainability of forest biomass logistics (in terms of GHG emissions) by introducing the dynamic aspects of the supply chain and using the geographical information system (GIS) and agent-based modelling (ABM). The use of the GIS and ABM adds local conditions to the assessment in order to make the study more relevant. In this study, GIS was used to investigate biomass availability, biomass supply points and the road network around a large-scale combined heat and power plant in Naantali, Finland. Furthermore, the temporal aspects of the supply chain (e.g., seasonal biomass demand and storage capacity) were added using ABM to make the assessment dynamic. Based on the outcomes of the GIS and ABM, a gate-to-gate LCA of the forest biomass supply chain was conducted in order to calculate GHG emissions. In addition to the domestic biomass, we added imported biomass from Riga, Latvia to the fuel mixture in order to investigate the effect of sea transportation on overall GHG emissions. Finally, as a sensitivity check, we studied the real-time measurement of biomass quality and its potential impact on overall logistical GHG emissions. According to the results, biomass logistics incurred GHG emissions ranging from 2.72 to 3.46 kg CO2-eq per MWh, depending on the type of biomass and its origin. On the other hand, having 7% imported biomass in the fuel mixture resulted in a 13% increase in GHG emissions. Finally, the real-time monitoring of biomass quality helped save 2% of the GHG emissions from the overall supply chain. The incorporation of the GIS and ABM helped in assessing the environmental impacts of the forest biomass supply chain in local conditions, and the combined approach looks promising for developing LCAs that are inclusive of the temporal aspects of the supply chain for any specific location.

Abstract:

Providing accurate real-time traffic information is an inherent problem for intelligent transportation systems (ITS). In order to improve the knowledge base of advanced driver assistance systems (ADAS), ITS are strongly concerned with data fusion techniques of all kinds of sensors deployed over the traffic network. Driver assistance is devoid of a comprehensive evidential reasoning system on contextual information, more specifically when a combination involves inside and outside sensory information of the driving environment. In this paper, we propose a novel agent-based evidential reasoning system using contextual information. Based on a series of information handling techniques, specifically, the belief functions theory and heuristic inference operations to achieve a consensus about daily driving activity in automatically inferring. That is quite different from other existing proposals, as it deals jointly with the driving behavior and the driving environment conditions. A case study including various scenarios of experiments is introduced to estimate behavioral information based on synthetic data for prediction, prescription, and policy analysis. Our experiments show promising, thought-provoking results encouraging further research.

Abstract:

This article presents some of the perceptions and experiences of mothers on public assistance and their social workers in three countries—Norway, Russia and the US. Based on in-depth interviews in each country with social workers and the women, five themes emerged that will be presented here. The mothers spoke of the inadequacy of economic support to meet their needs, a life of poverty that sometimes involved discrimination of them as mothers, and a loss of hope that their lives could be different. Two themes that stood out in the interviews with social workers was the lack of resources needed to help their clients and the dilemma faced as an agent of social welfare institutions balanced with being an advocate for the mothers’ needs.

Abstract:

The purpose of this study was to clarify the differences in relationships between grandmothers and grandchildren in Japan and South Korea. Ninety-seven and 194 pairs of grandmothers and grandchildren from Tokyo and Seoul, respectively, completed measures to assess their evaluations of four types of grandmother roles (“transmission”, “socialization agent”, “secure base”, and “parent surrogate”) and their degree of norms for assisting grandmothers. Only the role of socialization agent was associated with country difference, but not with any demographic factors; it was more highly evaluated by living in Seoul. The norm for assisting grandmothers was higher for both grandmothers and grandchildren in Seoul than in Tokyo. In Seoul, grandmothers' expectations of assistance positively correlated with grandchildren's sense of obligation; however, this was not the case in Tokyo. In addition, in Seoul, the grandmother role of a socialization agent was positively associated with the norm of assistance for both grandmothers and grandchildren. Based on these results, we argue that intergenerational solidarity is stronger in South Korea than in Japan, and that grandmothers in South Korea play influential roles in enhancing the norm of assistance.

Abstract:

AbstractThis research describes how the social safety net program, especially during the pandemic Corona virus in Pekanbaru, which has been going on for quite long. The method used in this research is a qualitative with descriptive analysis. Data collection techniques used were interviews, observation and documents related to the implementation of the assistance program. Furthermore, the data is processed through triangulation techniques. To analyze this implementation policy, the implementation theory of Van Meter and Van Horn is used by looking at 6 indicators of success they are goals, resources, implementing agents, implementing agent attitudes, agent communication and external environment. The results show that the implementation of the assistance program during the Covid-19 pandemic has been running from April 2020 to Desember 20202 when the program objectives were set. However, there is no similarity in implementation based on procedures due to factors, including the expansion of several sub-districts and the absence of a standard measure of success in implementing this assistance program in Pekanbaru.

Abstract:

This work aims to tackle the following two research questions regarding post-disaster rescues: how to optimize the rescue team dispatch based on the specialties of the team and the type of damage incurred, and how to optimize the allocation of injured patients to hospitals based on their symptoms, the rescue teams allocated, and the abilities of the hospitals to minimize fatalities. Rather than handling these two problems separately, we formulate them into an integrated system. A real-coded genetic algorithm is applied to minimize the estimated transport time in terms of distance, and the disparity between resource supply and demand. A set of scenarios is simulated and analyzed to provide insight for policy makers. Further, the simulated results can be used for future post-disaster medical assistance training.

Abstract:

With the revolution that the education field has known concerning the methods of learning and especially the integration of new technology, several new tools have appeared to replace the tools already existing, and among them there are serious games, serious games as new tool dedicated to education have occupied an important place, and replaced other tools often used in the learning process. But in the order that serious games reach the intended objectives and help instructors to achieve their perspectives considered, they must be equipped with a guidance and assistance system that will assist the learners during the progression in the sequence of the video game, and in addition, they must be equipped with a system of learning analytics that will help instructors to improve the learning process and teaching methods according to the learning outcomes and feedbacks of their learners. In this perspective of research and development we will establish in this paper a new system of assistance, guidance and learning analytics based on a multi agent system that will work in tandem with a web-based serious game.

Abstract:

This work surveyed residents of an economically disadvantaged community on their attitudes toward weatherization and their energy use behaviors. To support urban leaders making decisions to mitigate the effects of large-scale climate change, data-driven simulation models are being developed. To ensure that these models are equitable, the needs of all citizens must be included, especially those most vulnerable to the impacts of climate change. The results of this survey indicate that residents are taking steps to weatherize and conserve energy, but they are hindered by a lack of resources and knowledge of available assistance programs. These results are being applied to agent-based models (ABM) to model emergent community behavior. These models will be used to design decision support systems for city stakeholders.

Abstract:

The present article is elaborated in the context of e-learning softwares that provide assistance and functionalities to learners engaged in distance learning. Our contribution consists of a system that estimates a behavioral (sociological) profile for each student. This estimation is based on automatic analysis of students’ textual asynchronous conversations. In general, the automatic analysis of textual conversations is based on speech acts for classification and categorization of messages. This technique has several disadvantages like the absence of standardization of speech acts for determining social behaviors of learners. To overcome this, we propose a multi-agent system based on fuzzy logic reasoning and supervised learning technique for automatic classification and categorization of textual conversation. The determined profiles are proposed to teachers to provide them assistance during tutoring tasks. The objective of this article is to share our reflections around these issues by presenting our experience in the analysis of asynchronous online discussion forums. In this paper, we specifically propose (i) definitions for the used sociological profiles and (ii) introduce the architecture of the Multi-Agent System (MAS) that determines the profiles. The system was experimented with the students of the Master Program “Software Quality” in the Ibn Tofail University. The results obtained from this experience, presented and discussed in this paper, show that the proposed approach can be of interest.

Abstract:

In response to natural disasters, efficient planning for optimum allocation of the medical assistance to wounded as fast as possible and wayfinding of first responders immediately to minimize the risk of natural disasters are of prime importance. This paper aims to propose a multi-agent based modeling for optimum allocation of space to emergency centers according to the population, street network and number of ambulances in emergency centers by constraint network Voronoi diagrams, wayfinding of ambulances from emergency centers to the wounded locations and return based on the minimum ambulances travel time and path length implemented by NSGA𝜫 and the use of smart city facilities to accelerate the rescue operation. Simulated annealing algorithm has been used for minimizing the difference between demands and supplies of the constrained network Voronoi diagrams. In the proposed multi-agent system, after delivering the location of the wounded and their symptoms, the constraint network Voronoi diagram for each emergency center is determined. This process was performed simultaneously for the multi-injuries in different Voronoi diagrams. In the proposed multi-agent system, the priority of the injuries for receiving medical assistance and facilities of the smart city for reporting the blocked streets was considered. Tehran Municipality District 5 was considered as the study area and during 3 minutes intervals, the volunteers reported the blocked street. The difference between the supply and the demand divided to the supply in each Voronoi diagram decreased to 0.1601. In the proposed multi-agent system, the response time of the ambulances is decreased about 36.7%.

Abstract:

This study aimed to utilize a microwave technology to degrade active organic matters of the municipal dewatered sludge in a high-temperature environment. The effects of extraction agent, nanomaterial assistants, and microwave-absorbing agents and activating agents on the degradation efficiency were investigated. Dimethyl carbonate was used as the extraction agent. Nanostructured titanium oxide (TiO2) and zinc oxide (ZnO) exhibited effective assistance in the process of microwave treatment. We also developed a kind of microwave-absorbing agent, which was the sludge-based biological carbon. The sodium sulfate (Na2SO4), calcium hydroxide (Ca(OH)2), and magnesium chloride (MgCl2) were selected as activating agents to facilitate the organic matter discharging from the sludge. Through optimizing the experimental factors, it was confirmed that 0.1 wt% TiO2, 0.1 wt% ZnO, 2 wt% dimethyl carbonate, 10 wt% sludge-based biological carbon, 7.5 wt% Ca(OH)2, 0.5 wt% MgCl2, and 6 wt% Na2SO4 were the most appropriate addition amounts in the municipal dewatered sludge to make the organic matter decrease from 42.17% to 22.45%, and the moisture content reduce from 82.98% to 0.48% after the microwave treatment. By comparison, the organic matter degradation is almost zero, and the moisture content decreases to 8.69% without any additives. Moreover, the residual inert organic matter and sludge can be further solidified to lightweight construction materials by using liquid sodium silicate as the curing agent. The research provides a significant reference for the effective, fast, and low-cost treatment of the organic matter in the municipal sludge.

Abstract:

This article addresses a multi-agent approach to solving the problem of integrating metacognitive incentives into Learning Management System. The behavior of the teacher in a classroom-teaching situation, where teacher adopting the competency-based approach, is characterized by a set of didactic interventions dynamically adaptable according to the actions-reactions of the learners. These interventions are continually subjected to perfection by experience. In this article, we are interested in modeling the multi-agent system in order to help the learners develop their metacognitive skills in a continuous way. The purpose of this system is to supervise the activities and statements of the learner and communicate them to the metacognitive agent. The latter focuses on the assessment of the learner's metacognitive skills in order to trigger, automatically, metacognitive incentives to provide help messages. Integrating the agent for metacognitive control and assistance, allows learners to maintain motivation and confidence, and elicit their attention to the importance of metacognitive skills during learning activity. The "MaSE" methodology and the "agentTool" are used to model the multi-agent system.

Abstract:

With recent advances in mobile technologies and e-commerce infrastructures, there have been increasing demands for the expansion of collaboration services within and across systems. In particular, human collaboration requirements should be considered together with those for systems and their components. Agent technologies have been deployed in order to model and implement e-commerce activities as multi-agent systems (MAS). Agents are able to provide assistance on behalf of their users or systems in collaboration services. As such, we advocate the engineering of e-collaboration support by means of MAS in the following three key dimensions: (i) across multiple platforms, (ii) across organization boundaries, and (iii) agent-based intelligent support. To archive this, we present a MAS infrastructure to facilitate systems and human collaboration (or e-collaboration) activities based on the belief-desire-intension (BDI) agent architecture, constraint technology, and contemporary Web Services. Further, the MAS infrastructure also provides users with different options of agent support on different platforms. Motivated by the requirements of mobile professional workforces in large enterprises, the authors present their development and adaptation methodology for e-collaboration services with a case study of constraint-based collaboration protocol from a three-tier implementation architecture aspect. They evaluate our approach from the perspective of three main stakeholders of e-collaboration, which include users, management, and systems developers.

Abstract:

In order for a virtual environment to be effective as a training tool, it is not enough to concentrate on the fidelity of the renderings and the accuracy of the simulated behaviors. The environment should help trainees develop an understanding of the task and should provide guidance and assistance as needed. This paper describes a system for developing virtual environments in which pedagogical capabilities are incorporated into autonomous agents that interact with trainees and simulations of objects in the environment. These pedagogical agents can monitor trainee progress and provide guidance and assistance. This paper describes the architectural features of the environment and of the agents that accomplish the instructional objectives within the virtual environment. It also discusses how agent-based instruction is combined with other methods of delivering instruction.

Abstract:

AbstractIn recent years, approaches for information and control integration in the digital operating room have emerged. A major step towards an intelligent operating room and a cooperative technical environment would be autonomous adaptation of medical devices and systems to the surgical workflow. The OR staff should be freed from information seeking and maintenance tasks. We propose a closed-loop concept integrating workflow monitoring, processing and (semi-)automatic interaction to bridge the gap between OR integration of medical devices and workflow-related information management.Four steps were identified for the implementation of workflow-driven assistance functionalities. The processing steps in the closed loop of workflow-driven assistance could either be implemented with centralized responsible components or in a cooperative agent-based approach. However, both strategies require a common framework and terminology to ensure interoperability between the components, the medical devices (actors) and the OR infrastructure.

Abstract:

In this work, the devulcanization reaction of isobutylene–isoprene rubber (IIR)-based ground bladder rubber (GBR) in GBR/ethylene–propylene–diene monomer (EPDM) blend was investigated through a co-rotating twin-screw extruder. The influences of subcritical fluids (blank sample, water, ethanol, and n-propanol) and temperatures (160°C, 180°C, and 200°C) were investigated. The results confirmed the effectiveness of subcritical fluids in decreasing the gel content. Moreover, gel permeation chromatography analysis demonstrates that the devulcanizing processes with subcritical fluids are more homogeneous, making the molecular weight of sol detached from the devulcanized blend more uniform. Proton nuclear magnetic resonance spectra confirm that the reactivity of devulcanization of subcritical ethanol was the best. The optimal extrusion temperature for devulcanization is 180°C, at which the mechanical properties of the revulcanized IIR/(devulcanized ground bladder rubber [DGBR]/EPDM) blends achieve the best state. When promoting agent alkylphenol polysulfide (450) works with the assistance of subcritical ethanol at the best reaction condition (180°C, 2.0 MPa, and 500 r min−1), the tensile strength and elongation at break of the revulcanizate retain 94.7% and 110.2% of vulcanized IIR (15.91 MPa, 483.62%), respectively.

Abstract:

Mobile agent technology is an active research topic and has found its uses in various diverse areas ranging from simple personal assistance to complex distributed big data systems. Its usage permits offline and autonomous execution as compared to classical distributed systems. The free roaming nature of agents makes it prone to several security threats during its transit state, with an added overhead in its interoperability among different types of platforms. To address these problems, both software and hardware based approaches have been proposed to ensure protection at various transit points. However, these approaches do not ensure interoperability and protection to agents during transit over a channel, simultaneously. In this regard, an agent requires a trustworthy, interoperable, and adaptive protocol for secure migration. In this paper, to answer these research issues, we first analyse security flaws in existing agent protection frameworks. Second, we implemented a novel migration architecture which is: 1) fully inter-operable compliance to the Foundation for Intelligent Physical Agents (FIPA) and 2) trustworthy based on Computing Trusted Platform Module (TPM). The proposed approach is validated by testing on software TPM of IBM, JSR321, and jTPMTools as TPM and Trusted Computing Software Stack (TSS) interfaces, JADE-agent framework and 7Mobility Service (JIPMS). Validation is also performed on systems bearing physical TPM-chips. Moreover, some packages of JIPMS are also modified by embedding our proposed approach into their functions. Our performance results show that our approach merely adds an execution overhead during the binding and unbinding phases

Abstract:

Gold nanoparticles (GNPs) have tremendous potential as cancer-targeted contrast agents for diagnostic imaging. The ability to modify the particle surface with both disease-targeting molecules (such as the cancer-specific aptamer AS1411) and contrast agents (such as the gadolinium chelate Gd(III)-DO3A-SH) enables tailoring the particles for specific cancer-imaging and diagnosis. While the amount of image contrast generated by nanoparticle contrast agents is often low, it can be augmented with the assistance of computer image analysis algorithms. In this work, the ability of cancer-targeted gold nanoparticle–oligonucleotide conjugates to distinguish between malignant (MDA-MB-231) and healthy cells (MCF-10A) is tested using a T1-weighted image analysis algorithm based on three-dimensional, deformable model-based segmentation to extract the Volume of Interest (VOI). The gold nanoparticle/algorithm tandem was tested using contrast agent GNP-Gd(III)-DO3A-SH-AS1411) and nontargeted c-rich oligonucleotide (CRO) analogs and control (CTR) counterparts (GNP-Gd(III)-DO3A-SH-CRO/CTR) via in vitro studies. Remarkably, the cancer cells were notably distinguished from the nonmalignant cells, especially at nanomolar contrast agent concentrations. The T1-weighted image analysis algorithm provided similar results to the industry standard Varian software interface (VNMRJ) analysis of T1 maps at micromolar contrast agent concentrations, in which the VNMRJ produced a 19.5% better MRI contrast enhancement. However, our algorithm provided more sensitive and consistent results at nanomolar contrast agent concentrations, where our algorithm produced ~500% better MRI contrast enhancement.

Abstract:

Moodle is a widely deployed distance learning platform that provides numerous opportunities to enhance the learning process. Moodle’s importance in maintaining the continuity of education in states of emergency and other circumstances has been particularly demonstrated in the context of the COVID-19 virus’ rapid spread. However, there is a problem with personalizing the learning and monitoring of students’ work. There is room for upgrading the system by applying data mining and different machine-learning methods. The multi-agent Observer system proposed in our paper supports students engaged in learning by monitoring their work and making suggestions based on the prediction of their final course success, using indicators of engagement and machine-learning algorithms. A novelty is that Observer collects data independently of the Moodle database, autonomously creates a training set, and learns from gathered data. Since the data are anonymized, researchers and lecturers can freely use them for purposes broader than that specified for Observer. The paper shows how the methodology, technologies, and techniques used in Observer provide an autonomous system of personalized assistance for students within Moodle platforms.

Abstract:

Question generation aims to produce questions automatically given a piece of text as input. Existing research follows a sequence-to-sequence fashion that constructs a single question based on the input. Considering each question usually focuses on a specific fragment of the input, especially in the scenario of reading comprehension, it is reasonable to identify the corresponding focus before constructing the question. In this paper, we propose to identify question-worthy phrases first and generate questions with the assistance of these phrases. We introduce a multi-agent communication framework, taking phrase extraction and question generation as two agents, and learn these two tasks simultaneously via message passing mechanism. The results of experiments show the effectiveness of our framework: we can extract question-worthy phrases, which are able to improve the performance of question generation. Besides, our system is able to extract more than one question worthy phrases and generate multiple questions accordingly.

Abstract:

Co-worker safety support has been given prominence in manufacturing and transportation field for its positive effect on individual workers’ safety; however, there is little evidence to show if such supporting role of co-workers is significant in improving project-level safety performance in construction workplace. This study adopts agent-based modeling (ABM) to understand the effectiveness of two distinct co-worker-safety-support actions on the safety performance of a construction project. Based on the risk theory, the ABM model simulates a construction site where worker agents reinforce steel bars with the likelihood of suffering crane-related incidents. The results indicate that both co-worker-support actions can significantly reduce the occurrence of nonfatal incidents but shows little influence in fatal incidents, and in reducing high-severity incidents, the action of warning peers to leave the hazardous area has the same effectiveness as reminding peers to wear Personal Protective Equipment. The present study provides a fresh insight into the safety-related role of co-workers: not only reveals how the local-level effects of co-workers’ safety assistance emerge the system-level consequences, but demonstrates the effectiveness of specific peer-support actions on three levels of construction safety performance, and thereby extends our existing body of knowledge on co-worker safety support in the construction field.

Abstract:

This article asserts that the automated processing of information, such as via large-scale information systems in the Area of Freedom, Security and Justice (AFSJ), alters the 'value' of information from a means of assistance to a key decisional asset. Information in its different forms, whether paper-based or digital, has always been fundamental to decision-making conduct. Concretely, the premise holds that decisions shall be based on correct, full, and adequate knowledge and reasoning. Technological innovation has, however, magnified information capacities and significance. The article in that respect maintains that the 'decisional value' of automatically-processed information consequently also alters the nature of the respective decision-making – from a conventional type where the agent exercises discretion to a 'semi-automated' conduct in which automation inhibits the agent's decision-making capacity. The recognition of such transformation is necessary for the law to keep up with the technological progress and safeguard rights of individuals who are subjects of such semi-automated decisions.

Abstract:

Many studies on human–computer interaction have demonstrated that the visual appearance of an agent or a robot significantly influences people’s perceptions and behaviors. Several studies on the appearance of agents/robots have concluded that consistency between expectations from an agent’s or a robot’s appearance and performances was an important factor to the continuous use of these agents/robots. This is because users would stop interacting with the agents/robots when predictions are not met by actual experiences. However, previous studies mainly focused on the consistency between an initial expectation and a performance of a single instance of a task. The influence of the orders of successes or failures for more than one instance of a task has not been examined in detail. Therefore, in this study, we investigate the order effects of how the timing of sufficient or insufficient results of animated agents affects user evaluation. This will lead to the contribution to fill the lack of studies regarding more than one task in the field of human–computer interaction and to realize the continuous use of agents/robots as long as possible and to avoid stopping to use the agents/robots owing to their successful design. We create a simulated retrieval website and conduct an experiment using retrieval assistant agents that show both sufficient and insufficient results for more than one instance of retrieval tasks. The experimental results demonstrated a recency effect wherein the users significantly revised their evaluations of the animated agents based on new information more than that based on initial evaluations. The investigation of the case of repeated instances of a task and the influence of successes or failures is important for designing intelligent agents that may show incomplete results in intelligent tasks. Furthermore, the result of this study will contribute to build strategies to design behaviors of agents/robots that have a high or low evaluation based on their appearance in advance to prevent users from stopping use of the agents/robots.

Abstract:

Abstract The clinical problems caused by life-threatening, deeptissue fungal infections affect many different medical and surgical specialities where immunosuppression through disease or therapeutic advance has created a substantial sub-category of patients at risk of mycosis. Amphotericin B remains one of the first-line agents for treatment of almost all systemic mycoses, but the agent in its conventional deoxycholate formulation carries a serious penalty in terms of nephrotoxicity. Novel, lipid-associated formulations of amphotericin B have been introduced to combat the toxicity problem without loss of therapeutic efficacy. This supplement is based upon papers presented at an international symposium held in Australia on 8–9 July 2000. It focuses on AmBisome, a liposome-encapsulated formulation of amphotericin B, and draws together information on many general aspects of the diagnosis and treatment of deep tissue mycoses as well as providing a comprehensive set of reviews of all aspects of AmBisome —its pharmacology, toxicology, pharmacokinetics and clinical efficacy in a variety of mycoses and patient types. There is now considerably more clinical experience with lipid forms of amphotericin B than when the previous supplement on AmBisome was published by the Journal of Antimicrobial Chemotherapy in October 1999.1 Because the topic of the supplement is a formulation of an antifungal agent, not the agent itself, and because lipid-based formulations can vary in composition even when they are nominally prepared in the same way, we have taken the unusual step of referring to the various amphotericin B lipid formulations, and to ‘conventional’ amphotericin B-deoxycholate for injection, by their trade names. The editors would like to thank Christine Burley of the JAC Editorial Office, and Regine Buffels of Gilead Sciences for their untiring support and assistance in the preparation of this supplement.

Abstract:

Virtual machine tool has been used in the toolpath simulation of a real machine tool with very promising achievement in teaching assistance. However, a five-axis milling machine is generally very expensive in comparison with traditional three-axis milling machine in its configuration. This is mostly resulted from the addition of two more rotational axes in five-axis machine. This paper focuses on the development of a Web-based five-axis milling machining toolpath simulation system so as to facilitate the comprehensive understanding of students and to ease the explanation of operations. A user can access the developed system through the web browsers such as the Microsoft Internet Explorer and Google Chrome as long as the Java Runtime Environment and OpenGL are installed. Three general configurations of five-axis milling machine tool have been implemented including Head-Head, Head-Table, and Table-Table. Furthermore, five-axis post-processing is generally a bottleneck in the popularization of toolpath simulation. An intelligent distributed agent-based post-processor has been integrated in this system. For example, an APT file created by the usage of Catia CAD/CAM software according to a five-axis toolpath could be post-processed by the developed system for the generation of a five-axis NC program. This NC program could then be simulated in the proposed system. The developed system has been successfully implemented and shown very promising application in the understanding of five-axis milling operation.

Abstract:

Graphene sheets offer extraordinary thermal, electronic and mechanical properties which could enhance the performance of the device for various applications. However, a large quantity production and the direct dispersion of graphene or graphite sheets in water without the assistance of dispersing agent has been considered to be a challenging issue. In this study, we reported that by introducing the functional group on the graphene basal plane started from natural graphite can readily form stable graphene oxide (GO) solution in a large quantity through modified hummers method. Structural and physiochemical properties of the GO were investigated with help of Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR). The effects of the annealing treatment on a GO surface were analyzed using a Semiconductor Parameter Analyzer (SPA) in order to obtain the electrical resistance measurement. Based on the thermal reduction results, the resistance of drop casting is greater than spray coating which indicates that, the drop casting method is more reliable to be used in any application.

Abstract:

Object The aim of this study was to report on a novel technique in which metallic embolization coils were combined with the Onyx liquid embolic agent in the aneurysm sac to achieve a more durable result after endovascular treatment. This therapeutic procedure was performed in selected cases in which, based on the authors’ experiences, either coil embolization or Onyx alone would likely have failed. The authors report long-term clinical and angiographic follow-up results in 20 consecutive intracranial aneurysms treated using this combination for defined indications. Methods Twenty aneurysms in 20 patients were treated with a combination of embolic coils and Onyx. Four aneurysms were giant; 13, large; and three, small. This new technique was used when standard Onyx or coil treatment with balloon assistance was determined to involve a higher possibility of recanalization, because either an adjunctive stent insertion could not be performed or the Onyx technique could not be used due to an unsuccessful seal test or intraaneurysm balloon prolapse. In one case, an adjunctive stent was placed before coil placement and Onyx deposition to control the material in the sac of the aneurysm, which had a fusiform neck. All aneurysms were completely occluded after using this technique. No clinical or technical adverse events occurred in any of the cases. Follow-up angiography was performed in all patients: 3-year studies in six patients, 2-year studies in five, and 1-year studies in nine. None of these studies demonstrated aneurysm regrowth or parent artery occlusion. Conclusions The combination of the embolic coils and the Onyx liquid embolic agent provides very durable aneurysm occlusion for defined indications.

Abstract:

Flax fiber has high sensitivity to moisture, and moisture uptake leads to the decrease of mechanical properties and distortion in shape. This paper attempts to graft flax fabric with nano-clay, with assistance from a silane-coupling agent, in order to improve hygrothermal resistance. The nano-clay grafted flax fabric reinforced epoxy (FFRP) composite produced through vacuum assisted resin infusion (VARI) process were subjected to 80% RH chamber for 12 weeks at 20, 40 and 70 °C, respectively. Moisture uptake, dimensional stability, and tensile properties was studied as a function of humidity exposure. Through SEM and FTIR, the effects of hygrothermal exposure was elucidated. In comparison to control FFRP plates, nano-clay grafting decreases saturation moisture uptake and the coefficient of diffusion of FFRP by 38.4% and 13.2%, respectively. After exposure for six weeks, the retention rate of the tensile modulus of the nano-clay grafted flax fiber based FFRP increased by 33.8% compared with that of the control ones. Nano-clay grafting also reduces the linear moisture expansion coefficient of FFRPs by 8.4% in a radial direction and 10.9% in a weft direction.

Abstract:

Throughout the world and particularly in urban areas, population growth can be listed as a direct cause of the uprising use of personal vehicles in cities around the world. Such attitude may lead to dramatic consequences, not only economically, but socially and environmentally. To meet these challenges, and to promote the use of multiple means of public transports by citizens, public authorities and transport operators seek − within the framework of the implementation of connected cities projects and intelligent − to optimize the extraction as well as the exploitation of the multimodal information by developing Interactive Systems of Assistance to the Multimodal Movement (IAMM). However, finding the optimal multimodal path for a given person is far from being a simple matter. Indeed, each potential user may have different or unique preferences regarding the: cost and/or duration of his/her journey, number of mode changes, comfort or safety levels desired. In the present study, we propose a multi-agent system which, based on the parameters entered by each user, proposes the optimal paths in the Pareto sense, including different public transport modes, private cars and parking availability.
