The MST also has a ‘test distress alert’ function, which operates without sending a live notification to an MRCC. Pressing and holding down the distress button will illuminate it while the distress countdown is running. Status notifications will be indicated with a tick or cross at the bottom of the test page.
Recent Enhancement of Indian Bridge Management System
Published in Structural Engineering International, 2023
The proposed system will enable BIM be a one-stop solution for the management of bridges. The first step of the new integrated system will begin with the creation of a BIM model. The model can be created using design details and/or as-built information. This model if required is then exported to internet readable format. Such exported files are readable on a Photoshop platform also. Repeat file creation could be essential to enable live 3D BIM models to be created reflecting the distress and deterioration of bridge elements. Another method would be to attach a 3D LODE models for elements that show deteriorated sections. The LODE models created would be only for distressed elements. This would reduce the requirement for a total BIM model for the full bridge. This usage of 3D LODE models would also reduce the usage of disc storage space on computers or web servers. This model creation centre will form an important part of the BIM’s being used as a bridge management system. The model created for each bridge will be assigned a unique identifier on the network that will function as the address key for that bridge within the management system. All data related to this bridge will be stored only under that identifier. So multiple bridges on the network can be added on BIM platforms. Each bridge will have a unique identifier which will be used to store all future information relating to that bridge.

Over 2.5 M Americans currently live with a total hip replacement (THR), improving mobility and reducing pain despite advanced osteoarthritis (Kremers et al. 2014). Improving THR designs and post-op rehabilitation plans requires quantifying hip kinematics (i.e., joint angles) and kinetics (i.e., joint moments) during common activities, such as gait (Kirkwood et al. 1999; Heller et al. 2001; Kassi et al. 2005). For instance, hip kinematics and kinetics during gait can be combined with finite element modeling during in-silico simulations of THR device failure (Nunn et al. 1989; Haynes et al. 1997; Szivek et al. 2000). Further, these metrics can identify characteristics of pathologic gait to develop postoperative rehabilitation programs, such as abductor strengthening to prevent Trendelenburg gait in patients following THR (Hamacher et al. 2012). Despite this, current methods for quantifying hip kinematics and kinetics during gait are limited.

The Evolutionary Approach with the Attention Restoration Theory claims that nature can positively improve individuals’ ability to direct and refocus their attention. Direct attention is used to complex problem solving, which is a mentally demanding process (Kaplan 1995; Stigsdotter and Grahn 2002; Stigsdotter et al. 2011). The Aesthetic-Affective Theory (Stigsdotter et al. 2011) is underpinned by the Biophilia Hypothesis (Ulrich et al. 1991; Wilson 2002). This is based on the notion that humans have an inherited connection with nature and respond to this instinctively in a positive way. Urbanisation has disrupted this connection. This explains why people who live in urban environments have increased cortisol levels and stress-induced activity in the amygdala, which is involved in the fight or flight response (Stigsdotter and Grahn 2002; Lederbogen et al. 2011; Stigsdotter et al. 2011; Marcus and Sachs 2014).
