Embedded Electronics

Wearable electronics appear more frequently in the personal protective equipment market (PPE) primarily to assure information and alarm functions for the user. However, despite their advantages, there remain doubts concerning the level of protection that these devices can guarantee and their conformity to requirements laid down in PPE legislation. This paper investigates the factors that need to be assessed to confirm that such devices function correctly under anticipated use conditions. To this end, we considered a case study of an air-purifying fire escape respirator (APER) integrated with a radio-based positioning system and alarming device. In particular, we examined the parameters associated with the operation of the alarm and the information functions (the visibility and audibility of the alarm signals and the radio signal strength of the positioning system). This study provides evidence that the anticipated use conditions and the APER construction have a combined effect on the correct functioning of the embedded electronics. Based on these findings, we identified additional requirements that should be considered by PPE manufacturers at the design stage as well as by health and safety practitioners when evaluating the protection levels of PPE with embedded electronics.

Risk Assessment Method

Successful implementation of Health and Safety (H&S) systems requires an effective mechanism to assess risk. Existing methods focus primarily on measuring the safety aspect; the risk of an accident is determined based on the product of severity of consequence and likelihood of the incident arising. The health component, i.e., chronic harm, is more difficult to assess. Partially, this is due to both consequences and the likelihood of health issues, which may be indeterminate. There is a need to develop a quantitative risk measurement for H&S risk management and with better representation for chronic health issues. The present paper has approached this from a different direction, by adopting a public health perspective of quality of life. We have then changed the risk assessment process to accommodate this. This was then applied to a case study. The case study showed that merely including the chronic harm scales appeared to be sufficient to elicit a more detailed consideration of hazards for chronic harm. This suggests that people are not insensitive to chronic harm hazards, but benefit from having a framework in which to communicate them. A method has been devised to harmonize safety and harm risk assessments. The result was a comprehensive risk assessment method with consideration of safety accidents and chronic health issues. This has the potential to benefit industry by making chronic harm more visible and hence more preventable.

Moped-style scooters are one of the most popular systems of micro-mobility. They are undoubtedly good for the city, as they promote forms of environmentally-friendly mobility, in which flexibility helps prevent traffic build-up in the urban centers where they operate. However, their increasing numbers are also generating conflicts as a result of the bad behavior of users, their unwarranted use in public spaces, and above all their parking. This paper proposes a methodology for finding parking spaces for shared motorcycle services using Geographic information system (GIS) location-allocation models and Global Positioning System (GPS) data. We used the center of Madrid and data from the company Muving (one of the city’s main operators) for our case study. As well as finding the location of parking spaces for motorbikes, our analysis examines how the varying distribution of demand over the course of the day affects the demand allocated to parking spaces. The results demonstrate how reserving a relatively small number of parking spaces for scooters makes it possible to capture over 70% of journeys in the catchment area. The daily variations in the distribution of demand slightly reduce the efficiency of the network of parking spaces in the morning and increase it at night, when demand is strongly focused on the most central areas.

Crises can impact an organisation’s viability, credibility and reputation. Communication can preserve and protect the valuable reputation of an organisation, by demonstrating an acceptance of responsibility for the crisis and addressing victim concerns. The research illustrates that Maple Leaf Food’s crisis communication strategy was effectual and in supported to its purported organisational values as an organisation focused on health and safety. This case highlights why it is crucial for organisations to develop and apply a cohesive crisis communication strategy.

Important investmentsare made lately in the area of district heating, as a technology capable ofhelping countries to reach sustainability goals. In Romania, European fundswere spent for transition from the 2nd to the 3rdgeneration of district heating systems. The lack of appropriate monitoringsystems in old district heating systems makes optimisation nowadays very difficult,especially because nominal values used in the first design stage areoverestimated. Realistic nominal heat loads are necessary to make goodestimations of hydraulic parameters to be used for redesign. This studyproposes a method that uses the heat load duration curve theory to identify theappropriate nominal heat loads to be used for redesign. Comparison betweenresults obtained by applying the nominal heat loads of each consumer, as theywere established in the first design stage, and the ones identified by theproposed method are analyzed in a case study. The results show that errors arein the +/- 3% band, between the metered heat consumption rates and the proposedrates. The new method can be used for the sizing of pumps and district heatingnetworks after retrofit, in order to get better adjustments of the circulationpumps and increase of the energy efficiency.
