Cotton yarn is often spun from a mixture of distinct cotton bales. Although many studies have presented efforts to predict hairiness and strength from cotton properties, the heterogeneity of this mixture and its influence in such values have been neglected so far. In this work the properties of the cotton bale mixture are modeled as random variables and a robust variant of the Extreme Learning Machine (ELM) to address the cotton quality prediction problem is proposed. A real world dataset collected from a textile industry was used to compare the performance of the proposed model with a traditional ELM and a linear regression model. The results showed that the proposed method outperformed the benchmark methods in terms of Average Root Mean Square Error (ARMSE).

The main goal in Continuous Descent Arrival (CDA) operations is the management of flight trajectories in order to optimize the operating capability of the aircraft in Terminal Manoeuvring Area (TMA), reducing fuel burn and emissions during the descent/approach phase. At the same time the maximization of airspace efficiency/capacity needs to be addressed considering local airspace requirements and constraints. The arrival coordination task can be viewed as a scenario in which several aircraft approach at a common merging point within optimum time windows, ensured by ATC in order to eliminate en-route conflicts with an adequate sequencing of the arrivals. It is proposed a 4D-compliant framework that integrates the individual performance preferences of the landing aircraft and the ATC arrival management procedures. The ATC agent should use a particle swarm optimization algorithm in order to build valid, safe arrival sequencing that decreases and distributes the overall operational costs among the aircraft in a fair and efficient manner. Using actual data from Brasilia International Airport (SBBR) to evaluate the effectiveness of the proposed modeling, a case study shows that 77% of the flights are able to accomplish their desired time window flying a CDA procedure. © 2016 IEEE.

In this paper, a novel fuzzy LBP model for extracting texture features from medicinal plant leaves is proposed. The proposed method is invariant to image transformations and independent of any threshold. Concept of hierarchical clustering based on inconsistency coefficient is used to produce natural clusters for a particular species capturing intra-class variations due to environmental conditions and acquisition system. Interval valued type symbolic feature vector is used to represent each cluster effectively. Thus the proposed system suggests choosing multiple representatives for each species to make the representation more effective and robust. A chi-square distance measure is used to establish matching between the test and reference feature vectors of plant leaves and a nearest neighbor classification technique is used to classify an unknown test sample of medicinal plant leaf. Extensive experiments are conducted to demonstrate the efficacy of the proposed model on our own data set and other publically available leaf datasets. Results of the proposed work has been compared with the contemporary work and found to be superior. © 2015 IEEE.

Context: Despite being defined during the first phase of the Systematic Literature Review (SLR) process, the protocol is usually refined when other phases are performed. Several researchers have reported their experiences in applying SLRs in Software Engineering (SE) however, there is still a lack of studies discussing the iterative nature of the protocol definition, especially how it should be perceived by researchers conducting SLRs. Objective: The main goal of this study is to perform a survey aiming to identify: (i) the perception of SE researchers related to protocol definition; (ii) the activities of the review process that typically lead to protocol refinements; and (iii) which protocol items are refined in those activities. Method: A survey was performed with 53 SE researchers. Results: Our results show that: (i) protocol definition and pilot test are the two activities that most lead to further protocol refinements; (ii) data extraction form is the most modified item. Besides that, this study confirmed the iterative nature of the protocol definition. Conclusions: An iterative pilot testcan facilitate refinements in the protocol.

AHP-based metric for tie strength of online friendships

Not all friends have the same importance to an individual, and even the importance of a friend can vary over time. In order to keep friends close, online relational maintenance strategies can be employed. The knowledge about the tie strength of an online relation can be useful to social, technical or commercial purposes. In this paper, we define a metric for tie strength in online friendships. We investigate variables related to friendship maintenance as well as their relative importance. Analytic Hierarchy Process (AHP) is a decision method used to find the relevance of the selected variables. We conduct experiments that show a high acceptance of the metric based on assessments of real users.

Online teams are useful due to both flexibility and facility to gather resources originally dispersed. However, its intrinsic characteristic of separation in space and time imposes challenges to participation. Belief in task significance has positive effects on moving members to participate, while incentive mechanisms can be added to foster participation. Coordination is a central to a successful collaboration, since it guides members' participation. As participation is driven by motivation, we focus on motivation. We conducted an experiment to analyze the effects on motivation of the following aspects: task significance, quality of team coordination, and usage of incentive mechanisms. We discuss the relevance of these aspects;the characteristics that make them contribute to or interfere on online motivation;as well as the interplay among the aspects that can increase or reduce the aspects' effect.

Improving robustness in multi-robot networks

IFAC-PapersOnLine 2015年第19期48卷 63-68页

This paper addresses the topological robustness of robot networks under failures; a subject often neglected in the literature. Robots are likely to fail due to several causes, which may lead to a poorly connected or a fragmented network. Our purpose is to discuss how to design resilient robot networks. For that, we first demonstrate the problem analyzing the results from a protocol to simulate failures of both central and random (w.r.t. topology) robots. Then, we propose mechanisms for detecting the probability of a robot being in a fragile local configuration and for improving its local robustness. The procedures rely solely on local information: each robot estimates its probability of being in a harmful configuration based on the positions of its neighbors. Such probability is estimated as the number of paths connecting a robot to its 2-hop neighbors by the number of paths existing in the subgraph encompassing its 1-hop and 2-hop neighborhoods. For reversing an adverse configuration, robots change their position to an average position towards their 2-hop neighbors with fewer alternative paths. The results showed that the proposed mechanism is efficient for detecting fragile topological configurations and for improving the overall network robustness. © 2015, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd.

SoftCoDeR approach: promoting Software Engineering Academia-Industry partnership using CMD, DSR and ESE

Journal of Software Engineering Research and Development 2016年第1期4卷 1-21页

The Academia-Industry partnership has been increasingly encouraged in the software development field. The main focus of the initiatives is driven by the collaborative work where the scientific research work meets the real needs of the Industry. Aiming to contribute to this effort we have proposed an approach called SoftCoDeR (Software Cooperative Design Research) that combines CMD (Cooperative Method Development), a method of Action Research, to concepts of DSR (Design science Research). We have applied the SoftCoDeR approach in a software development company to support a research and development project aiming to integrate User Experience practices into the agile software development process. In this paper, we present new findings about this approach that has been extended with the use of Experimental Software Engineering (ESE) practices to conduct experimental validations of artifacts before putting them in industrial practice.
