This paper presents a procedure for supporting Brazilian universities during the selection of students to receive a social assistance grant, resulting from the Brazilian the National Student Assistance Program (PNAES) for reducing student evasion in public universities. The procedure is based on the multi-criteria method PROMETHEEII and on the ROC (Rank-Order-Centroid) approach. The procedure was...
Fuzzy Cognitive Maps have been widely used for modeling complex systems but time and evolution of the system has not sufficiently been illustrated and taken into consideration within the FCM model. Time is a substantial aspect for any application because factors determining the behavior of the system evolve over time; they affect and change the route of any evolution of the system. This work further...
2D-video-based gait recognition techniques have been studied for decades, but there are still many challenges, one of which is the robustness against the variation of view angle. In this paper, the second generation Kinect (Kinect V2) is used as a tool to establish a 3D-skeleton-based gait database, which includes both 3D information of the skeleton joints and the corresponding 2D silhouette images...
It is difficult for the deafblind or the hearing impaired to control the pitch of their voice because they cannot perceive it. In particular, when singing, it is very difficult for them to control their voice pitch because they need to maintain a stable tone. We have developed a voice pitch control system to assist such people in their singing by means of a tactile display. Using this tactile feedback...
We propose a pitch track correction technique using a sigmoidal objective function in a particle filtering framework. The conventional method for pitch track correction simply considers the peak locations of the autocorrelation functions as the pitch values and depends only on the longest reliable pitch streak. This constraint may induce pitch correction errors. The proposed approach uses particle...
A cooperative negotiation and problem solving method, ANC (Automated Negotiation and Case-based reasoning), is proposed in this paper. The goal of this method is to provide a suitable smart home service for multiple user requirements. The motivation in this paper is that agreeing on a common service is difficult when different users propose different requirements. Therefore, in ANC, cooperation negotiation...
This paper describes experimental results of extracting features of students majoring in humanities and sciences, in order to show factors that influence the selection when students select their course, i.e. humanities or sciences. In the research, data are collected through questionnaires to students. The questionnaire includes questions to ask about the lifestyle, and subjects studied in schools...
The scientific community has devoted attention to virilization in hard real-time systems, motivating the development of many hierarchical scheduling techniques for dealing with stringent timing constraints for such systems. Most techniques are based on runtime scheduling methods and they provide important results concerning schedulability analysis. However, there are situations in which runtime methods...
This paper investigates how to allocate quota permits for initial discharge from industrial point sources in a lake basin. The model takes fairness, efficiency and feasibility as basic principles. By introducing a weighted lexicographic minimization of the maximum initial discharge permit shortage rate for different industrial point sources, this paper proposes a quota allocation model and furnishes...
This paper proposes a novel adaptive cruise control (ACQ system for vehicles that addresses the issues of fuel economy, tracking capability, and driver desired response. The controller is synthesized by applying an adaptive optimal control (AOQ algorithm. A cost function is developed that considers the conflicting objectives of high fuel economy, minimizing tracking error, and providing a driver desired...
This paper tries to generate an appropriate concurrency control program by using genetic programming (GP). In GP, a program is represented with a tree. Nodes of a tree are selected from a symbol set. This paper tries two symbol sets: the high-level symbol set and the reduced one. The high-level one includes high-level symbols created by combining conventional ones. In the reduced symbol set, symbols...
In this note, we present the modeling of nonlinear dynamical systems with Quasi-ARX neural network using Lyapunov algorithm in learning process. This work exploits the idea on learning algorithm in nonlinear kernel part of Quasi-ARX model to improve stability and fast convergence of error. The proposed algorithm is then employed to model and predict a classical nonlinear system with input dead zone...
Mixed-Initiative-Systems (MIS) are hybrid decision-making systems in which human and machine collaborate in order to produce a solution. This paper described an MIS system adapted to business optimization problems. These problems can be solved in less than an hour as they show a linear structure. However, this delay is unacceptable for iterative and interactive decision-making contexts where users...
Traction motor systems for electric vehicles provides fast torque response that may let the driver input result in excessive propelling or regenerative braking torque, which can reduce tire-road adherence. The same situation can also occur due to excessive wheel slip that tends to spin or skid the wheels, resulting in safety issues or energy losses. However, to measure the slip ratios for vehicle...
In the actual situation of sound e nvironment systems, the observed data often contain several fluctuating noises. Therefore, it is necessary to estimate the specific signal based on the observed data by introducing some noise cancellation methods. In this study, a sound environment system considering both noises of the external noise based on the additive property of energy variable and the inter...
In this paper, we apply GVF snake to vertebra segmentation and further improve it based on the knowledge of spine MRI, especially the shape knowledge. Owning to the contour of vertebra body being similar to a rectangle whose edges are concave to the center of the contour, we add a pressure force which moves the contour to the center as one of the external forces of snake, and then reset the weight...
The human mind creates and interprets beautiful literature. Perhaps one of the greatest challenges for Machine Intelligence is the replication of those skills. ‘Semantic Category Theory’ indicates that human language cognition is based upon four distinct data types that can be combined in one of two ways. The analytical adjunct to Semantic Category Theory, ‘Semantic Category Analysis’, determines...
Computer aided design (CAD) system for traditional Chinese paper-cutting provides significant assistance for folk artists creating delicate handicrafts. However, the large amount of paper-cutting patterns creates several major challenges for the management of an online pattern library. Artists could easily collect favorite pattern materials and share their creative works with others using an online...
Avionics system has many uncertainties at runtime, software self-evolution was proposed for changing behaviors of runtime software systems. Software cybernetics makes better use of the interplay between control theory and software engineering. In this paper, we present a cybernetics approach called Self-Evolving Control (SEC) after analysis the software evolution and software cybernetics. This approach...
We suggested a joint algorithm for opportunistic spectrum and time sharing in cognitive radio (CR) wireless mesh networks (WMNs) in this paper. The problem was formulated using linear programming and solved by the simplex-II method. The flow optimization problem was first developed for grid topology of CR WMNs. Results showed optimized flow of the CR WMNs with ideal interference free link scheduling...
