Monitoring of historical structural materials with computed tomography

Structural Concrete, EarlyView.
Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).

An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

High Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

The First World War at Sea: Death, Commemoration and Cultural Remembrance

History, EarlyView.
Abstract Despite the ever‐increasing body of work devoted to war memorials, national days of remembrance and the commemoration of the First World War in Britain, academic focus remains firmly on the commemoration of the First World War on land. Yet, while the number of people who died at sea paled in comparison to their counterparts on the battlefield ...

Design and Development of a Wall-Pressed Robot for In-Pipe Inspection

IOP Conference Series: Materials Science and Engineering
Pipelines have become a major part of energy infrastructure, which requires a secure and reliable means of maintenance. It has become critical to introduce advanced robotic methods for inspecting pipelines in order to offer a more secure alternative to ...

PARTY‐STATE URBANISM: Coevolution of Local State Capacity and Strategic Alliances in Shenzhen

International Journal of Urban and Regional Research, EarlyView.
Abstract What is distinct about Chinese urban governance? Classic theories predict that when the central state retreats from resource allocation, capacity‐strained local governments must form alliances with non‐state actors, thereby diluting state power. In China, however, state power remains dominant despite decentralization.

In-Pipe Inspection Micro Robot Adaptable to Changes in Pipe Diameter

Journal of Robotics and Mechatronics, 2003
In the development of a microrobot for inspecting the inside of pipes with an internal diameter of 1 to 3 inches, the author of this paper designed an in-pipe mobile mechanism adaptive to pipe diameter based on a snake robot and evaluated it theoretically and experimentally. The authors fabricated 2 robots of different size. The first, Prototype A, was

The informal prisoner justice system: Classification, identification, and punishment of sex offenders behind bars

Criminology, EarlyView.
Abstract Drawing on 576 interviews with incarcerated men and 131 correctional staff across five Western Canadian prisons, we reconceptualize the prison code as subcultural law, documenting the “informal prisoner justice system” as its enforcement arm. Although scholars have treated the code primarily as cultural values prescribing loyalty, silence, and

Head Gestures Do Not Serve as Precursors of Prosodic Focus Marking in the Second Language as They Do in the First Language

Language Learning, EarlyView.
Abstract Research shows that children use head gestures to mark discourse focus before developing the required prosodic cues in their first language (L1), and their gestures affect the prosodic parameters of their speech. We investigated whether head gestures also act as precursors and bootstrappers of prosodic focus marking in second language (L2 ...

A Coordinated Wheeled Gas Pipeline Robot Chain System Based on Visible Light Relay Communication and Illuminance Assessment

Sensors, 2019
The gas pipeline requires regular inspection since the leakage brings damage to the stable gas supply. Compared to current detection methods such as destructive inspection, using pipeline robots has advantages including low cost and high efficiency ...

Development of Internal Gas Pipe Inspection Robot

Journal of Robotics and Mechatronics, 1995
This paper describes a new mechanism and communication system for an in-pipe inspection robot. To date, inspection robots have been limited as to their mobility to turn in a T -shaped pipe or move in a plug valve. The new mechanism based on our dual magnetic wheels overcomes these limitations without difficult controls.
