4. QUALITY ANALYSIS FOR THE VRP SOLUTIONS USING COMPUTER VISION TECHNIQUES
ABSTRACT The Vehicle Routing Problem (VRP) is a classical problem, and when the number of customers is very large, the task of finding the optimal solution can be extremely complex. It is still necessary to find an effective way to evaluate the quality of solutions when there is no known optimal solution. This work presents a suggestion to analyze the qualit

5. A Software-in-the-Loop Simulation Scheme for Position Formation Flight of Multicopters
ABSTRACT The cooperative control of small unmanned aerial vehicles such as the multicopters has been extensively investigated worldwide for functionality augmentation and cost reduction with respect to a single larger vehicle. The present paper proposes a software-in-the-loop simulation scheme for performance evaluation and demonstration of formation flight

6. Measured Dielectric Permittivity of Contaminated Sandy Soil at Microwave Frequency
Abstract Measurement of dielectric permittivity of soil has been studied by many researchers. However, few studies have been conducted on contaminated soil. The motivation of the present study is to investigate the behavior of sandy soil contaminated by lubricant oil at microwave frequency. Two different artificially prepared soil samples are measured in the

8. Construção de um programa de ensino de pré-requisitos de leitura e escrita para pessoas com deficiência intelectual / Development of program to teach reading and spelling prerequisites for students with intellectual disabilities
Since its dawn, Behavior Analysis stood out in the search for ways of teaching complex repertoires to persons with intellectual retardation. Procedures built on stimulus equivalence have proved highly effective and economical, especially with regard to academic and symbolic skills. In Brazil, there is a tradition of successful research concerning the teachin

11. Architecture for generic detection of machine code injection in computer networks
Since the creation of public exploitation frameworks, advanced payloads are used in computer attacks. The attacks generally employ evasion techniques, have anti-forensics capabilities, and use target machines as pivots to reach other machines in the network. The attacks also use polymorphic malicious code that automatically transforms themselves in semantica

12. Teaching opportunities-methodological present in social network orkut: contributions to the teaching of chemistry / Possibilidades didático-metodológicas presentes na rede social Orkut: contribuições para o ensino de química
The information and communication technologies (ICTs) have changed the ways of society to communicate, and relate mainly to learn. This expansion and popularization of technology, more specifically the interconnection of personal computer to the Internet were called cyberspace (LÉVY, 1999). In this form, relations hips occur in the virtual world so that whi
