Opis:
The purpose of this study was to compare the effect of quadriceps isometric exercises along with hip abductors isometric exercises as integrated exercise with quadriceps exercises in reducing pain, disability in medial knee osteoarthritis. The Total of 54 patients (both male and female) were recruited in this study but on the basis of inclusion and exclusion criteria, only 32 were included in this study. Womac index was opted as outcome measures to collect the data of pain, disability and functional limitation. Participants were randomly assigned to integrated exercise group; (n = 16) (mean age 52) who performed exercises [Quadriceps isometric along with hip abductor isometric exercises] and quadriceps isometric exercises group (n = 16) (mean age 49) performed for 3 weeks. 32 patients were analyzed and the effect of integrated exercises [Quadriceps isometric along with hip abductor isometric exercises] showed a statistically significant difference in pain, disability and functional limitation (p < 0.000). Total duration to collect the pre and post data of pain, disability and functional limitation was 3 weeks. 3 weeks of exercise protocol was effective in both groups in terms of reducing pain and disability but integrated exercises were found to be more effective than quadriceps exercise in improving the pain, disability and functional limitation over the time at the level of significance.

Opis:
Automation of earth moving machineries is a widely studied problem. This paper focusses on one of the main challenges in automation of the earth moving industry, estimation of loading torque acting on the machinery. Loading torque acting on the excavation machinery is a very significant aspect in terms of both machine and operator safety. In this study, a disturbance observer-assisted control system for the estimation of loading torque acting on a robotic backhoe during excavation process is presented. The proposed observer does not use any acceleration measurements, rather, is proposed as a function of joint velocity. Numerical simulations are performed to demonstrate the effectiveness of the proposed control scheme in tracking the reaction torques for a given dig cycle. Co-simulation experiments demonstrate robust performance and accurate tracking of the proposed control in both disturbance torque and position tracking. Further, the performance and sensitivity of the proposed control are also analyzed through the help of performance error quantifiers, the root-mean-square (RMS) values of the position and disturbance tracking errors.

Opis:
Air quality problems in cities are often a cause for worry. The air quality index is increasing daily, leading to an increase in cancer and many respiratory problems. Road transport in an urban area is a significant cause of air pollution. The vehicles must meet Indian emission regulations for which the emissions are measured using legally mandated standard driving cycles that did not accurately reflect real-world driving emissions because of varying traffic conditions, meteorological conditions, driving behaviour, vehicle power, performance, etc. This study focuses on real-time emissions of gaseous pollutants hydrocarbon (HC), carbon dioxide (CO2), carbon monoxide (CO), and nitric oxide (NO) from vehicle exhaust pipes under heterogeneous traffic conditions. The emissions were measured using a Portable Emission Measurement System (PEMS). The PEMS used was an AVL MDS 450 analyser mounted on the vehicle, and onroad emissions were captured. The test sample consists of four passenger vehicles with varying engine sizes, manufacturers, and fuel. The test route comprises city and highway areas, and it was discovered that the emissions were reduced by 40 to 70% on highways compared to the city. In petrol BSIV and BSVI engines, the emission was reduced to 41.73% for CO, 46.90% for HC, and 64% for NO in the city area. Speed and emissions scatter graphs were plotted for the vehicles, and it was found that in the city area, the optimum speed for less emission is between 30-40 km/h, and on highways, the optimum speed is 80-90 km/h. The emissions were also sensitive to the rate and frequency of acceleration and decelerations. This type of study is very limited in India, and more such studies are required for the assessment of air quality in metropolitan areas and successful traffic management strategies, as well as for determining instantaneous projections of pollutant emissions.
