Regulations on worker exposure to diesel particulate matter (DPM) are becoming increasingly stringent in the mining industry. Due to the complexity and unpredictability of this aerosol, there is a need for new tools to help mines develop an effective strategy to reduce DPM concentrations. To address these needs, NIOSH has developed a portable elemental carbon monitoring device for use in underg...

Recent embedded computing platforms offer multiple independent clocks for different components involved in processing a single instruction stream, such as CPU and memory, giving rise to a new category of power management policies, called MultiDVS, where the different components can be clocked down to different degrees, independently. This paper presents the first MutliDVS scheme with dynamic po...

The goal of this research work is to improve the accuracy of human pose estimation using the Deformation Part Model (DPM) without increasing computational complexity. First, the proposed method seeks to improve pose estimation accuracy by adding the depth channel to DPM, which was formerly defined based only on red-green-blue (RGB) channels, in order to obtain a four-dimensional DPM (4D-DPM). I...

Diesel particulate matter (DPM) is considered to be carcinogenic after prolonged exposure. With more diesel-powered equipment used in underground mines, miners' exposure to DPM has become an increasing concern. This paper used computational fluid dynamics method to study the DPM dispersion in a dead-end entry with loading operation. The effects of different push-pull ventilation systems on DPM ...

Purpose – The purpose of this paper is to investigate how to measure collaborative design performance and, in turn, improve the final design output during a design process, with a clear objective to develop a design performance measurement (DPM) matrix to measure design project team members’ design collaboration performances. Design/methodology/approach – The methodology adopted in this researc...

Free-roaming dogs and rabies transmission are integrally linked across many low-income countries, and large unmanaged dog populations can be daunting to rabies control program planners. Dog population management (DPM) is a multifaceted concept that aims to improve the health and well-being of free-roaming dogs, reduce problems they may cause, and may also aim to reduce dog population size. In t...
