Automating the process of drawing floor heating systems on to floor plans
Floor heating is a common method for space heating in Iceland and requires authorization from building regulatory authorities in the form of a permit before integration. The permit is only provided if necessary documentation is admitted, a design of the floor heating system along with technical …

Floor Vibration Design Criterion For Cold-Formed C-Shaped Supported Residential Floor Systems
Annoying floor vibration due to normal human activity was investigated for cold-formed C-shaped residential floors systems. Dynamic impact and static loading tests were performed on twelve full size laboratory floors and five two-joist line laboratory floors to determine the influencing …

Floor-supply displacement ventilation system
… to the occupied zone. However, the existing floor-supply displacement ventilation systems have some problems. Hence, the objective of this research was to improve the disadvantages of the current system, and to develop a new design for the floor-supply displacement ventilation system with …

Algorithms above the noise floor
… of non-convex sets up to the statistical noise floor. * In unconstrained optimization, we prove that important convex problems already require approximation if we want to find a solution quickly. * In nearest neighbor search, we show that approximation guarantees can explain much of the good …

The Culture of the Floor
A beautiful floor, a forgotten element, draws the eye down, a rare direction to view architecture. The presence of a floor, realized through travel, led to a curiosity about the patterns adorning the surface and an architecture generated by the floor. A pattern becomes a floor when lines turn into …

Active control of floor vibrations
… is often not considered a dynamic system, is the floor of a building. In many cases the dynamics of a floor system are neglected in the design phase of a building structure. Occasionally, this omission results in a floor which has dynamic characteristics found to be unacceptable for the intended …

Development of shop floor control system
This thesis presents a scheduling algorithm for production planning, which involves the management of resources like equipment, tools, personnel, materials etc. The scheduling algorithm implements some of the principles of Just-In-Time manufacturing and hence has a combination of finite and …

Pelvic floor dysfunction in female triathletes
… with adverse effects, including pelvic floor disorders. Nevertheless, there is very little in the literature about pelvic floor effects associated with endurance sports where high-impact exercise is performed at submaximal intensity for prolonged periods of time. Objective: The primary …

Improving shop floor visualization and metrics
… is a lack of adequate visualization on the shop floor. The current status and schedule of production cannot be quickly seen at the tools where the work is being performed. This thesis focuses is on improving the visualization and creating a set of KPIs (Key Performance Indicators) and visual …

Control of human induced floor vibrations
With the growing demand for open, column-free floor spaces and the advances in material strength, floor vibration serviceability criterion has been of growing importance within the past 20-30 years. All floor systems are flexible and when introduced to a dynamic loading respond in a vibratory …

Evaluation of A "Floating" Aerobics Floor
Aerobics dance floors often produce annoying floor vibrations in adjacent parts of a building due to the rhythmic impact of the aerobicists. Various types of shock absorbing aerobics and dance floors are widely used to prevent injuries to the participants, but the floors may not prevent vibrations …

Vibration acceptability in wood floor systems
… research conducted on laboratory-built floors. Floors were built and tested to determine the plywood contribution to increasing the bending stiffness, number of joists effective in resisting applied load, and calculation of fundamental frequency. The second section summarizes research …

Methods to reduce transient floor vibrations
Modern lightweight floor systems are susceptible to annoying vibrations induced by the forcing action of human locomotion. This investigation considered several experimental methods to reduce unwanted floor motion as well as analytical procedures aimed at a better understanding of the phenomenon. A …

Sounding the Floor: Advancing Inclusive Firefighter Culture
This study examined work-related and personal factors contributing to disparities in career experiences within the Calgary Fire Department (CFD). Drawing on participants’ insights and a review of relevant literature, the research explored firefighting culture, experiences of inclusion and …

Mechanistic modelling of single-floor office environments
… deployment of a single base station in a single-floor office environment is considered. The environment is systematically divided into several generic canonical geometries including an open plan office and corridor, a single corner, a double corner, and a discrete obstacle which are then …

Assessing sales floor capacity and replenishment strategy
Target stores (and the upstream supply chain) have been traditionally designed for a predominantly brick and mortar business, fed by a push supply chain model. With the growing need for omnichannel sales fulαllment, supply chain engineering has become signiαcantly more complex. Based on the …

Deflection comparisons of different wooden floor systems
… structural deflection tests were conducted on floor sections with 2"x4" , 2"x6", and 2"x8" joists at four different stages of construction. Stage A was joist alone; stage B joists plus 1/2" plywood subflooring; stage C, stage B plus 25/32" oak strip flooring laid parallel to the joists; and …
