Output only based modal analysis of a reduced scale building using digital camera images

The article discusses a proposal of displacement measurement using a unique digital camera aiming at to exploit its feasibility for Modal Analysis applications. The proposal discusses a non-contact measuring approach able to measure multiple points simultaneously by using a unique digital camera. A modal analysis of a reduced scale lab building structure based only at the responses of the structure measured with the camera is presented. It focuses at the feasibility of using a simple ordinary camera for performing the output only modal analysis of structures and its advantage. The modal parameters of the structure are estimated from the camera data and also by using ordinary experimental modal analysis based on the Frequency Response Function (FRF) obtained by using the usual sensors like accelerometer and force cell. The comparison of the both analysis showed that the technique is promising noncontact measuring tool relatively simple and effective to be used in structural modal analysis

Assimetria no controle postural em idosos caidores e não caidores neurologicamente sadios e com doenã de Parkinson em diferentes posições estáticas

Individuals with Parkinson's disease (PD) seem to present asymmetric postural control, and the commitment to postural control that is a big factor of falls in this population. However, the asymmetry in the postural control of fallers and non fallers with PD and neurologically healthy elderly is not too much studied. The objective of the study is to analyze the asymmetry in postural control in different static positions of elderly patients with PD and healthy elderly fallers and non fallers. The study included 70 older adults with PD and 70 neurologically healthy (CG). The groups were matched for age, gender, height, weight and cognitive condition. It was evaluated the clinical, cognitive status and incidence of falls among its participants through weekly prospective follow-up of 4 months. Then, for each group, CG and PD, it was selected 12 elderly fallers and 12 elderly non fallers to evaluate postural control. Participants were evaluated through two force platforms in conditions of bipedal support, unipedal and tandem position. It was realized 3 attempts of 30s for each condition. For unipedal and tandem condition it was made 3 attempts for each lower limb. The parameters of interest of the center of pressure (CoP), were analyzed for each condition and compared by MANOVAs with factor group, fall and asymmetry. Post hoc Tukey tests were used to determine the relationships between them. The results show that CG individuals showed greater velocity and CoP area in relation to PD. It was verified that at the control group that non fallers individuals (CGN) had more displacement and RMS in the average lateral direction in the dominant limb when compared to the less affected limb of non fallers with PD (PDN). Faller individuals in the control group (CGF) had larger area in the non dominant limb when compared to the most affected leg of fallers individuals with PD (PDF). Still, the PDF individuals had higher RMS in anteroposterior feeling....

Tractor perfomance as a function of speed and seeder s tire inflation pressure

O desempenho de tratores agrícolas em condições de campo resulta da interação entre pneu e rodado, influenciado pela velocidade de deslocamento. O objetivo deste trabalho foi avaliar o desempenho de um trator agrícola sob diferentes pressões de inflação dos pneus da semeadora (518, 483, and 414kPa) e em duas marchas que proporcionaram velocidades de 3,0 e 6,0km h-1. O experimento foi realizado no campus de Jaboticabal da Universidade Estadual Paulista (UNESP). O delineamento experimental utilizado foi fatorial inteiramente casualizado (3x2), com quatro repetições. A força de tração foi influenciada pela marcha e pela potência exigida; no entanto, a pressão de inflação do pneu da semeadora não alterou esses parâmetros. Além disso, o consumo de combustível foi influenciado apenas pela marcha do trator. O consumo de energia foi maior com o aumento da velocidade, ocasionada pela mudança de marcha. A velocidade de deslocamento foi maior para a pressão de 518kPa, em razão da menor patinagem da semeadora promovida por essa pressão. A patinagem do trator não foi alterada pelos fatores testados.
