Physical workload

The primary aim of this research was to further develop the sensing and estimation module of the CHMS framework with an improved multimodal inference model of MWL as needed for the application in aerospace CPHS. Here the focus of this research was on the implementation of a multimodal inference model of MWL that would be developed and experimentally tested. This was done with the purpose of studying the viability of real‐time system adaptation in aerospace systems.

Job rotation has often been used in situations where the level of exposure cannot be reduced due to the characteristics of the job or through physical measures. However, the effectiveness of the job rotation strategy at preventing musculoskeletal complaints lacks adequate scientific data.

: It is usually assumed that musculoskeletal pain is associated with both the physical workload and the psychosocial work environment, as well as with personal and lifestyle factors. This study aims to ascertain the prevalence of musculoskeletal pain in women with varying or different occupational exposures, and to explore the associations between musculoskeletal pain and the occupational and personal factors.

There is consistent evidence from observational studies of an association between occupational lifting and carrying of heavy loads and the diagnosis of hip osteoarthritis. However, due to the heterogeneity of exposure estimates considered in single studies, a dose-response relationship between cumulative physical workload and hip osteoarthritis could not be determined so far.

Knee osteoarthritis (OA) is the most common form of arthritis affecting the elderly. Understanding the risk factors for knee OA has been derived from cross sectional studies. There have been few longitudinal studies of risk factors for knee OA among Asian populations.

e-Learning has been widely used in educational settings especially in developing countries like Indonesia. The purpose of this study was to investigate e-learning readiness among Indonesian university students and to compare students’ perceptions of their workload (including mental demand, physical demand, temporal demand, performance, effort, frustration, and sleepiness) in e-learning and classical learning settings. A survey was conducted with students in an Indonesian university. The results show that students have a high level of e-learning readiness.

The present findings focuses on the assessment of anthropometrical, physical and physiological characteristics undergone by male operators during weeding operation. The variations were measured prior to and after the commencement of weeding activity. The VO2max and AWL was 27.59 mL/Kg min and 9.61 respectively.

Consolidation of applications in cloud computing environments presents a significant opportunity for energy optimization. As a first step toward enabling energy efficient consolidation, we study the inter-relationships between energy consumption, resource utilization, and performance of consolidated workloads. The study reveals the energy performance trade-offs for consolidation and shows that optimal operating points exist. We model the consolidation problem as a modified bin packing problem and illustrate it with an example.

A materialized view (MV) is a more complex physical design structure than an index since a materialized view may be defined over multiple tables, and can involve selection, projection, join and group by. This richness of structure of MVs makes the problem of selecting materialized views significantly more complex than that of index selection. First, for a given query (and hence workload) the space of materialized views that must be considered is much larger than the space of indexes. For example, MVs on any subset of tables referenced in the query may be relevant.

The role of the workload, including queries and updates, in physical design was widely recognized. Therefore, at a high level, the problem of physical database design was - for a given workload, find a configuration, i.e. a set of indexes that minimize the cost. However, early approaches did not always agree on what constitutes a workload, or what should be measured as cost for a given query and configuration. Papers on physical design of databases started appearing as early as 1974.

To transcend these limitations, Greenplum assembled a team of the world’s leading database experts and built a shared-nothing massively parallel processing database, designed from the ground up to achieve the highest levels of parallelism and efficiency for complex BI and analytical processing. In this architecture, each unit acts as a self-containe database management system that owns and manages a distinct portion of the overall data. The system automatically distributes data and parallelizes query workloads across all available hardware.

This monograph describes a model for evaluating the combined capacity of organic (U.S. Air Force–owned and –operated) and contractor maintenance assets to meet aircraft programmed depot maintenance (PDM) workloads. The PDM Capacity Assessment Tool (PDMCAT) forecasts the average number of aircraft that will be in PDM status each year over several decades,1 based on the initial number of aircraft in PDM status, the physical capacity of the facility or facilities (number of docks available for conducting PDM work),...

Growth in wireless services is increasing the number of copper and fiber cables that must be managed – causing an increased workload for reconfigurations and maintenance. Meeting the challenge of increasing profits in the face of fewer capital and operating resources to manage this steadily growing and more complex wireless network infrastructure requires improvements in operational efficiency from Network Operations.
