Abstract:

The failure of civil engineering structure will lead to heavy losses. So, identifying structural damage is necessary as early as possible. The excellent localization performance of lifting wavelet transform will facilitate significantly damage diagnosis. On the base of wavelet energy distribution of structural acceleration response, taking advantage of characteristics of lifting wavelet and entropy, the structural damage identification method based on lifting wavelet entropy is proposed in this paper. And the lifting wavelet time entropy index and the relative lifting wavelet entropy index are

Abstract:

This paper presents an index that quantitatively characterizes different dynamic postural strategies employed during sagittal plane lifting. The dynamic lifting strategy is analyzed in the velocity domain as a strategy of partitioning postural changes between the torso and leg segments. The index consists of two parameters, assigned to two leg segments, which quantify their contributions relative to the torso. Parameter values, ranging from 0.1 to 10, are estimated through a simple enumeration search. The use of this index is illustrated by applying it to 24 lifting movements performed by six

Manual lifting techniques are commonly defined in terms of the postures adopted at the start of the lift. Quantitative definition is problematic, however, because the absolute joint angles adopted to lift an object are influenced by task parameters, such as the initial height of the load. We present an argument for the use of a postural index (the ratio of knee flexion from normal standing to the sum of ankle, hip, and lumbar vertebral flexion) to define the postures adopted at the start of lifting. Stooped postures adopted at the start of a lift correspond to postural indices close to 0, wher

Abstract:

In this study, we have analyzed the behavior of shear and compression forces at the L5-S1 joint during the execution of controlled lifting tasks designed on the basis of the revised NIOSH (National Institute for Occupational Safety and Health) lifting equation (RNLE) with an increasing lifting index (LI = 1, LI = 2, and LI = 3). We aim to verify the sensitivity of force indices with regard to risk levels. Twenty subjects performed the tasks, and the kinematic and kinetic data of their movement were acquired by using an optoelectronic motion analysis system and platform, respectively. Lumbosacr

Abstract:

The crop divider is a crucial component of the sugarcane chopper harvester that has an important effect on the lifting performance of lodged sugarcanes. However, tropical weather and climate result in severe sugarcane lodging, which seriously hinders the sugarcane lifting process. To improve the lifting performance of crop dividers, a variable-spiral spike-toothed crop divider was designed. Some structural parameters of the bench test were designed. In this study, the forward speed, the rotational speed of the scrolls, and the installation angle of the scrolls were selected as test factors and

Dari pengamatan awal didapatkan bahwa cara pengangkatan yang dilakukan masih belum ergonomis. Dengan menggunakan metode Recommended Weight Limit (RWL), didapatkan bahwa Lifting Index (LI) untuk metode awal >1.83. Hal ini menandakan bahwa resiko cedera yang dihadapi pekerja sangat besar. Oleh karena itu, cara pengangkatan yang dilakukan perlu diubah. Adapun cara kerja yang diusulkan adalah dengan memakai alat bantu berup

Abstract:

The sugarcane lifting–cutting System (SLS) is the core component of the sugarcane harvester, and the influence of its stalk lifting height on the mechanism of perennial root-cutting damage is still unclear. The test was conducted with the vertical height of centroid (VHC), forward velocity, and cutter rotational speed. Numerical quantification of perennial root based on the cutting breakage effect and cutting breakage grade (CBG) classification was used as the evaluation index. The test results showed that the VHC had a highly significant effect on the CBG of the perennial root. The CBG of the

Abstract:

Work-related low-back disorders (WLBDs) can be caused by manual lifting tasks. Wearable devices used to monitor these tasks can be one possible way to assess the main risk factors for WLBDs. This study aims at analyzing the sensitivity of kinematic data to the risk level changes, and to define an instrument-based tool for risk classification by using kinematic data and artificial neural networks (ANNs). Twenty workers performed lifting tasks, designed by following the rules of the revised NIOSH lifting equation, with an increasing lifting index (LI). From the acquired kinematic data, we comput

Abstract:

The newly revised NIOSH lifting guide offers a multiple task strategy for frequency weighting multiple lifting tasks performed in a series; in close proximity of time. This strategy allows calculation of a composite lifting index (CLI) during assessment of jobs for which lifting variables are changing throughout the task. While the approach is useful, the number of calculations and table look-up procedures required is much larger than a single task strategy requires, and the process becomes tedious and error prone if performed manually. Consequently, a computer program was developed by Contine

This study aimed to investigate the physical effects of precision lifting tasks on the maximal acceptable weight of a lift (i.e., psychophysiological lifting capacity where the workers adjust the lifting weight in order to work without any fatigue or strain at the end of the work while wearing common safety shoe types). Additionally, the physical difference between the precise and non-precise lifting conditions associated with wearing safety shoes were assessed by respiration responses and shoe discomfort ratings. To achieve the objective of the study, ten healthy male workers were selected by

Abstract:

Trunk kinematics (i.e. speed and acceleration), a risk factor associated with low back pain (LBP), is difficult to measure in the field and is not incorporated in popular lifting analysis tools. In this study, computationally efficient computer vision-based methods were used to estimate trunk kinematics from video recordings collected in a previous prospective study. We explored the relationships between trunk kinematics and health outcomes, and if incorporating trunk kinematics into the revised NIOSH Lifting Equation (RNLE) may improve its predictability of LBP risk.

Two-year-old transplants and undercuts of Piceasitchensis (Bong.) Carr. and Pseudotsugamenziesii (Mirb.) Franco were cold-stored (1 °C) for 1 to 7 months ending in April 1989. Their physiological arid morphological condition at lifting and after storage was assessed and related to survival and height increment on a reafforestation site after one growing season. Physiological assessments made between October and April at lifting were root growth potential, tolerance of fine roots to chronic cold, shoot and root mitotic index, root elongation, and electrolyte leakage from the shoot and roots.
