The National Association of Architectural Metal Manufacturers (NAAMM) provides consensus products for specifications, procedures, and terminology for metal bar grating, expanded metal, hollow metal doors and frames, metal flagpoles, metal stairs and railings, and metal lathing and furring.   As an ANSI accredited standards developer it provides public commenting opportunities on its consensus products; linked below:

We encourage our colleagues to communicate directly with the standards staff at NAAAM: Vernon (Wes) Lewis, 123 College Place #1101, Norfolk, VA 23510, (757) 489-0787, wlewis7@cox.net.  At the moment we find no public commenting opportunities but on selected holidays we revisit its flagpole standard.  Keep in mind that this document has a scope that is limited to the product and its appropriate application and maintenance only:

Non-Contact Heart Rate Monitoring in Neonatal Intensive Care Unit using RGB Camera

Non-Contact Heart Rate Monitoring in Neonatal Intensive Care Unit using RGB Camera

Quiong Chen, et. al

Abstract:  Heart rate (HR) measurement is crucial for newborn infant monitoring in the neonatal intensive care unit (NICU). The widely used contact HR measurement methods based on electrocardiography (ECG) and photoplethysmography (PPG) signals can lead to discomfort and possible skin irritation on neonates, which limit its application in NICU scenarios. In this work, we propose a non-contact HR monitoring method simply using a RGB camera. Eulerian video magnification (EVM) is employed to detect the subtle changes of neonatal faces results from blood circulation. The magnified signal is then transformed to the spectral domain to extract HR information. Compared with the widely investigated independent component analysis (ICA)-based HR measurement method using video recordings, the proposed method can achieve the real time HR measurement, which is a significant superiority in NICU neonatal monitoring. To the best of our knowledge, this is the first study to employ EVM algorithm in real time neonatal HR monitoring.

Church heating: Comparison of different strategies

N. Aste. et al

Department of Architecture, Built Environment and Construction Engineering, Politecnico di Milano

 

Abstract:  Church heating represents a challenging task because multiple goals have to be fulfilled simultaneously, such as the thermal comfort for the occupants and the optimal internal environmental conditions for the preservation of building components and artworks. In addition, current requirements for environmental and economic sustainability impose to make efforts to minimize the amount of energy needed and the consequent environmental/economic impact. In this context, the present work represents the assessment of the energy, environmental and economic impact of different strategies for church heating, including a novel technology based on the exploitation of renewable energies. The analysis was carried out in a real case-study building, represented by the Basilica di S. Maria di Collemaggio (L’Aquila, Italy), a church of worldwide relevance, currently under restoration.

“I think we ought to read only the kind of books that wound or stab us. If the book we’re reading doesn’t wake us up with a blow to the head, what are we reading for? So that it will make us happy, as you write? Good Lord, we would be happy precisely if we had no books, and the kind of books that make us happy are the kind we could write ourselves if we had to. But we need books that affect us like a disaster, that grieve us deeply, like the death of someone we loved more than ourselves, like being banished into forests far from everyone, like a suicide. A book must be the axe for the frozen sea within us. That is my belief.”
― Franz Kafka

Critical Operations Power Systems: Improving Risk Assessment in Emergency Facilities with Reliability Engineering

Abstract. The key feature of this article is the application of quantitative method for evaluating risk and conveying the results into a power system design that is scaled according to hazards present in any given emergency management district. These methods employ classical lumped parameter modeling of power chain architectures and can be applied to any type of critical facility, whether it is a stand-alone structure, or a portion of stand-alone structure, such as a police station or government center. This article will provide a risk assessment roadmap for one of the most common critical facilities that should be designated as COPS per NEC 708-a 911 call center. The existing methods of reliability engineering will be used in the risk assessment.
