A preliminary investigation on the sound field properties in the Sagrada Familia Basilica

This paper reports on a preliminary investigation of the sound field properties inside a large Roman Catholic Church in Barcelona, the Sagrada Familia Basilica, which is a World Heritage Site although its construction has not been completed. The impulse responses were measured at 5 sound source positions combined with 14 measurement locations inside the Sagrada Familia Basilica, and the Impulse response to Noise Ratios (INR) were examined to check the reliability of the measured impulse responses. The room acoustic parameters were calculated and the following 5 sound field properties in the Sagrada Familia Basilica were analysed: reverberation, spaciousness, loudness, warmth and clarity. No optimal values of room acoustic parameters for such large volume churches have been found in the literature; thus, the preferred values of the reverberation time (T20) and the Early Decay Time (EDT) for small volume churches, and the preferred values of the middle frequency strength of sound (Gmid), the low frequency strength of sound (G125), the clarity (C80) and the binaural quality index (1 - IACCe) for concert halls were compared with the measurement results to illustrate a primary impression of the listening experience in the Sagrada Familia Basilica. The reverberation time (T20) and the EDT in the Sagrada Familia Basilica are much higher than the preferred values, while the middle frequency strength of sound (Gmid), the low frequency strength of sound (G125) and the clarity (C80) are less than the preferred values. The binaural quality index (1 - IACCE) is just above the typical satisfactory value

System remotely inspects, measures, and records internal irregularities in piping

Video electromechanical probe visually inspects and measures internal offset and peaking of welds in relatively large piping. Irregularity dimensions are recorded on peripheral equipment consisting of video tape and X-Y plotter. The probe is used for inspection of vacuum-jacketed liquid lines that cannot be inspected externally

Understanding social behaviors in the indoor environment: a complex network approach

Being able to monitor and analyze human interactions in the indoor environment over time has many architectural applications from spatial planning to post occupancy evaluation. In this paper, we present our interdisciplinary approach that interprets human-spatial interactions as a complex network. We combine methods and techniques from sensor networks, signal processing, data mining, network theory, and information visualization to form a novel framework that facilitates versatile investigations. We will demonstrate the framework with a real-world case study: we have collected and analyzed human-spatial interaction data from a workshop scenario where multiple design projects were conducted within a shared studio space

Fabricate 2020

Fabricate 2020 is the fourth title in the FABRICATE series on the theme of digital fabrication and published in conjunction with a triennial conference (London, April 2020). The book features cutting-edge built projects and work-in-progress from both academia and practice. It brings together pioneers in design and making from across the fields of architecture, construction, engineering, manufacturing, materials technology and computation. Fabricate 2020 includes 32 illustrated articles punctuated by four conversations between world-leading experts from design to engineering, discussing themes such as drawing-to-production, behavioural composites, robotic assembly, and digital craft

The Development of a Well-Being Program for Occupational Therapy Graduate Students

High levels of stress among occupational therapy graduate students have led to the adoption of unhealthy coping habits such as poor nutrition, little exercise, and disrupted sleep. In response, many institutions have explored programming and even curricular changes to support student well-being. However, very few are built upon a strong theoretical foundation to address holistic well-being. Therefore, this paper describes how logic modeling was used to develop a student well-being program based on Facilitating Learning and Occupational Well-Being Using Research-Based Initiatives for Student Health (FLOURISH), a theoretical approach rooted in the Person-Environment-Occupation Performance Model. A well-being program delivered via a virtual community of practice for entry-level students at a Midwestern occupational therapy program was created to decrease stress and enhance overall well-being for the performance of learning. The program consisted of eight 50-minute sessions that met once per week and included topics of physical, mental, sociocultural, environmental, and occupational well-being. The student well-being program is one viable option that shows promise to empower students with a theoretical approach to address personal and professional well-being, which has the potential to translate into professional practice. In this article, we describe the well-being program and the theoretical approach in detail and illustrate how it can be used to improve occupational therapy student well-being

A multimodal toolkit for thermal performance feedback in conceptual design modelling

This paper presents a multimodal toolkit for rapid performance-driven façade design that includes both virtual and physical performance feedback. The toolkit has been user tested in the SmartGeometry 2013 event by the Thermal Reticulations workshop cluster. Although the workshop participants were predominately digital design focused, the authors observed several distinct approaches to the tool selection and workflow involving both physical and virtual simulations, with a favoring to tools that produce fast visual outcomes. The approaches to tool selection are presented here as case studies with their workflow mapped for discussion. We conclude that access to a diverse range of simulation tools for design evaluation is advantageous to the creativity of the design process

Pharmacological interventions for agitation in patients with traumatic brain injury: protocol for a systematic review and meta-analysis

Abstract Background Traumatic brain injury (TBI) is a worldwide leading cause of mortality and disability. Among TBI complications, agitation is a frequent behavioural problem. Agitation causes potential harm to patients and caregivers, interferes with treatments, leads to unnecessary chemical and physical restraints, increases hospital length of stay, delays rehabilitation, and impedes functional independence. Pharmacological treatments are often considered for agitation management following TBI. Several types of agents have been proposed for the treatment of agitation. However, the benefit and safety of these agents in TBI patients as well as their differential effects and interactions are uncertain. In addition, animal studies and observational studies have suggested impaired cognitive function with the use of certain antipsychotics and benzodiazepines. Hence, a safe and effective treatment for agitation, which does not interfere with neurological recovery, remains to be identified. Methods/design With the help of Health Sciences librarian, we will design a search strategy in the following databases: PubMed, Ovid MEDLINE®, EMBASE, CINAHL, PsycINFO, Cochrane Library, Google Scholar, Directory of Open Access Journals, LILACS, Web of Science, and Prospero. A grey literature search will be performed using the resources suggested in CADTH’s Grey Matters. We will include all randomized controlled, quasi-experimental, and observational studies with control groups. The population of interest is all patients, including children and adults, who have suffered a TBI. We will include studies in which agitation, not further defined, was the presenting symptom or one of the presenting symptoms. We will also include studies where agitation was not the presenting symptom but was measured as an outcome variable and studies assessing the safety of these pharmacological interventions in TBI patients. We will include studies evaluating all pharmacological interventions including beta-adrenergic blockers, typical and atypical antipsychotics, anticonvulsants, dopamine agonists, psychostimulants, antidepressants, alpha-2-adrenergic agonists, hypnotics, and anxiolytics. Discussion Although agitation is frequent following TBI and pharmacological agents that are often used, there is no consensus on the most efficacious and safest strategy to treat these complications. There is a need for an updated systematic review to summarize the evidence in order to inform practice and future research. Systematic review registration PROSPERO CRD4201603314
