Abstract Objective The Automated Neurological Assessment Metrics (Version 4) Traumatic Brain Injury Military (ANAM4 TBI-MIL) battery is widely used by the US military to assess cognitive function. We compare intra-individual agreement between ANAM4 TBI-MIL and a battery of traditional neuropsychological tests using rates of low scores. Methods Complete and valid data from 246 healthy soldiers and 177 soldiers ≤7 days from sustaining mild TBI (mTBI) were used in this analysis. All soldiers were consecutively administered ANAM4 TBI-MIL and a traditional test battery consisting of: TOPF, WAIS-IV, CVLT-II, RCFT, DKEFS, and CPT-II. We performed base rate analyses of both batteries to determine the proportions of soldiers who had various numbers of scores that were 1.0+, 1.5+, and 2.0+ standard deviations below the normative mean. We used those rates to place Soldiers into a “low score hierarchy” ranging from the least poor (i.e. ~≥10th %ile) to the worst overall performance (i.e. ~≤10th %ile). We then compared agreement between the batteries at each of those levels. Results More soldiers with mTBI had low scores than healthy soldiers on both batteries. Of the soldiers who performed at the worst level on one battery, 88.1% from ANAM and 100% from traditional had some level of poor performance on the other battery. However, of the soldiers who performed at the worst level on either battery, only 58.3% from ANAM and 50.0% from traditional also performed at the worst level on the other battery. Conclusion These batteries similarly identify poor performance to a degree, though with some potentially meaningful differences still present.

Overall Performance

A detailed dynamic model of the stump-prosthesis system for an above knee amputee was developed. The model was used to examine the influence of controls and design parameters on the limb system performance during the swing phase of gait. The model duplicated the clinically known fact that hydraulic knee controllers allow the amputee to change walking speed while mechanical knee controllers limit the amputee to a single walking speed. Contrary to current practice, the simulations suggest that light weight prosthesis designs do not perform as well as heavier designs. A simple design based on a constant friction knee is shown to yield good overall performance.

To reduce weight and improve overall performance of the industrial welding robot, light-weight design using the finite element method and structural topological optimization is presented in this paper. The work analyzed an upper arm of an industrial welding robot in the most unfavorable working condition, both under static and dynamic working situations, using ABAQUS and ADAMS software tools. Then the Tosca unit in ABAQUS was employed to accomplish the structural topological optimization, in order to reduce weight and improve the natural frequencies under the situation of low orders. The analyses results showed that the actual weight had been reduced to 17.9%, and the natural frequencies in low orders had increased. The maximum Mises stress, tensile stress, and elastic displacement of the gyration center had decreased. Lastly, an actual product was produced according to the model obtained from preceding analyses. The experiments of the repeatability tests showed that the overall performance of the optimized upper arm had been improved when compared to the original one. This research can present references and foundations for the kinetic analyses under the static and dynamic working conditions, and structural topological optimization designs for relative industrial welding robots.

Abstract: The history of Agriculture in India dates back to Indus Valley Civilisation. India ranks second worldwide in farm outputs. As of 2018, agriculture employed more than 50% of the Indian workforce and contributed 17–18% to the country's GDP. India has the largest net cropped area, followed by the US and China, yet mechanization in farming is comparatively low compared to developed countries. The lack of technological development and unaffordability of new and competent machines for the average farmer are the few of the reasons for this encumbrance. The development of the onion harvester intends that it will provide a reliable and affordable alternative to traditional farming practices. The digging and conveying systems are the integrated part of the onion harvester. The design of the blade and conveyor is made by using CATIA V5 and analysis of the parts are done using ANSYS Workbench. During design and analysis, severe factors are considered such as preventing the damage to onion bulbs, size of bulbs, soil condition, onion leaves at a predetermined height and roots of the crops to penetrate. This paper is intended to discuss the results of the design and analysis of the digging and conveying systems under the guidelines of the SAE TIFAN rulebook [1]. Keywords: Onion Harvester, Blade Design, Conveyor Design, FEA Analysis.

The USA has the world's largest economy and the highest per capita spending on healthcare, but it lags behind other countries on a number of key health measures. It ranks 23rd in healthy life expectancy and 32nd in infant mortality (World Health Organization, 2009). In 2000, the World Health Organization ranked the US healthcare system as 1st in responsiveness, 37th in overall performance, and 72nd by overall level of health (among 191 member nations in the study).

Engine Bearing

In modern higher power, compact and light weight automotive engines, bearing load is increasing and housing stiffness is decreasing. Consequently, the bearing performance is significantly influenced by elastic deformations of both the housing and the bearing. The effects of changing both the housing stiffness and the bearing dimension on bearing performance were studied by using the elastohydrodynamic lubrication theory on connecting rod bearings for diesel engines.

Light weight materials which possess high strength and durability are being utilized by the automotive industry to increase fuel economy. Rapidly solidified (RS) Al alloys are currently being extensively studied for this purpose. In this investigation the microstructure of an extruded Al-8Fe-2Mo alloy, produced by Pratt & Whitney Aircraft, Goverment Products Div. was examined in a JE0L 2000FX AEM. Both electropolished thin sections, and extraction replicas were examined to characterize this material. The consolidation procedure for producing this material included a 9:1 extrusion at 340°C followed by a 16:1 extrusion at 400°C, utilizing RS powders which have also been characterized utilizing electron microscopy.
