13. Quadriceps muscle weakness influences the gait pattern in women with knee osteoarthritis
Abstract Background: Osteoarthritis is the most prevalent rheumatic disease in the population and is characterized by limitation of main functional activities of daily living, as the gait. Muscle strength is a variable that may be related to performance in daily tasks. Therefore, we to analyze the gait pattern in individuals with knee osteoarthritis (KOA) a

14. SHORELINE MONITORING BY GNSS-PPP AIMING TO ATTENDANCE THE LAW 14.258/2010 FROM PERNAMBUCO STATE, BRAZIL
Abstract The geodetic shoreline positioning has socioeconomic importance due to decision-making support related to the coastal zone. The Pernambuco state, Brazil, has established a state law no. 14.258/2010 sanctioned as part of Coastal Zone Management State Policy. The state act no. 42.010/2015 enacted the baseline information for Pernambuco shoreline. Cons

15. REAL TIME PPP APPLIED TO AIRPLANE FLIGTHT TESTS
Abstract The availability in real time of GNSS satellites orbits, clock corrections and code and phase biases provided the possibility of application of Real Time Precise Point Positioning (RTPPP). This paper presents the methodology concerning RTPPP and application to kinematic trajectories of airplane flight tests, but without using the carrier phase bias.

16. POSTURAL COMPARISON BETWEEN A CONVENTIONAL BICYCLE HANDLEBAR AND AN ELLIPTICAL HANDLEBAR
RESUMO Introdução O ciclismo vem sendo incentivado, não apenas como forma de diminuir a poluição ambiental, mas também para melhorar a saúde das pessoas. Para muitos, a bicicleta é o único meio de transporte. Diante desse crescimento e do possível risco de lesões devido ao uso excessivo da bicicleta, foi desenvolvido um guidão elíptico com o p

17. INTEGRATION OF A LOW-COST GLOBAL NAVIGATION SATELLITE SYSTEM TO A SINGLE-BOARD COMPUTER USING KALMAN FILTERING
ABSTRACT The global navigation satellite system (GNSS) is the basis for localized crop management by allowing the georeferencing of collected data and the generation of maps by different systems that compose precision agriculture. There is a demand for low-cost navigation systems to enable their use in agriculture. Therefore, the objective of this study is t

18. Integrated Guidance and Control of Multiple Interceptor Missiles Based on Improved Distributed Cooperative Control Strategy
ABSTRACT In this study, an improved cooperative integrated guidance and control (IGC) design method is proposed based on distributed networks to address the guidance and control problem of multiple interceptor missiles. An IGC model for a leading interceptor is constructed based on the relative kinematic relations between missiles and a target and the kinema

19. A MEASUREMENT SYSTEM BASED ON LiDAR TECHNOLOGY TO CHARACTERIZE THE CANOPY OF SUGARCANE PLANTS
ABSTRACT Laser sensor applications associated with LiDAR (Light Detection and Ranging) technology on platforms allow the evaluation of crop and forest biomass in a non-invasive way. This study presents the development of a measurement system based on LiDAR technology aimed at the proposed assessment of the height of sugarcane plants during the pre-harvest pe

20. THE INFLUENCE OF THE FIRST PASS ON THE VOLLEYBALL BLOCKERS’ DECISION-MAKING
RESUMO O presente estudo examinou a informação que constrange a tomada de decisão dos bloqueadores no jogo de voleibol, referente à antecipação da jogada adversária. Foi investigado o papel da informação do voo da bola, que emerge da interação entre o passador e o levantador. No primeiro experimento foi feita análise cinemática da trajetória da

21. Reconfiguration of multi-stage tensegrity structures using infinitesimal mechanisms
Abstract The use of tensegrity structures in soft robotics has seen an increased interest in recent years thanks to their mechanical properties, but the control of these systems remains an open problem. This paper presents a reconfiguration strategy for actuated multi-stage tensegrity structures. The algorithm works on the principle of using the infinitesima

22. EQUAÇÕES LINEARES E NÃO LINEARES PARA PREVER O COMPORTAMENTO DE PROPRIEDADES FÍSICO-QUÍMICAS DE COMBUSTÍVEL DE AVIAÇÃO MISTURADO COM BIOQUEROSENE DROP-IN ALTERNATIVO
Density, viscosity and calorific values are important physical properties to affect the utilization of biofuel. In this work, mixtures of farnesane and a “jet fuel”, QAv-1, were used to study the variation of density and kinematic viscosity as a function of the volumetric fraction of farnesane and temperature. Experimental measurements were carried out f

23. AVALIAÇÃO DE CARACTERÍSTICAS DE BIODIESEIS DE FONTES ALTERNATIVAS SUBMETIDOS A CONDIÇÕES DE ARMAZENAGEM DIFERENCIADA
Biodiesel is an alternative fuel obtained from different biomass sources and processes. Nowadays, this biofuel has gained importance due to environmental concerns and rising energy demand. In the biodiesel production chain, stability is a critical issue, as it is linked to the maintenance of its original properties. This work performed a study evaluating the

24. THERMOGRAVIMETRIC APPROACH FOR ASSESSING THE OXIDATION LEVEL OF A BIODIESEL SAMPLE
Biodiesel, unlike diesel, is highly susceptible to autoxidation. This autoxidation is a major concern for a biodiesel producer. Various methods have been developed to estimate the degree of oxidative stability of biodiesel. These methods are useful to compare and estimate the oxidative stability between different biodiesel samples. However, an absolute value
