Terahertz human body security images have low resolution and a low signal-to-noise ratio. In the traditional method, image segmentation, positioning, and identification are applied to detect objects carried by humans in ...

Carbon Dioxide, CO2 (R744) was one of the first commonly applied working fluids in the infancy of refrigeration more than 100 years ago. In contrast to ammonia it mainly disappeared after the first generation of synthetic ...

Collision avoidance systems are a key ingredient in developing autonomous surface vehicles (ASVs). Such systems require real-time information about the environment, which can be obtained from transponder-based systems or ...

In the presence of snow, the bias in the prediction of surface albedo by many climate models remains difficult to correct due to the difficulties of separating the albedo parameterizations from those describing snow and ...

In this study, path-loss and shadowing measurement results for three different industrial indoor environments at 900, 1600, and 2450 MHz are presented. The results show that the one-slope model fits the measured path-loss ...

Objective: To perform a radiological review of mammograms from prior screening and diagnosis of screen-detected breast cancer in BreastScreen Norway, a population-based screening program. Methods: We performed a consensus-based ...

Background Novel cancer drugs are subject to strict scientific evaluation of safety and efficacy and usually undergo a cost effectiveness analysis before approval for use in clinical practice. For new techniques in ...

Contemporary tools used to monitor railway points and crossings are ineffective. Routine inspections of these critical parts are still being performed manually by specially-trained inspectors. This creates higher expenditure ...

Increasing demands for more cost-effective, reliable and safer railway infrastructure unavoidably bring up the need for transitioning from current preventive maintenance strategies to more efficient, predictive, condition-based ...
