P3 - Porous Pareto Partition
(2020-02-29)Unsustainable and Misaligned Economics of Technology triggers a Porous Pareto Partition Between the Haves and the Have Nots: Can Democratization of Distributed Data act as a Catalyst for the Dissemination of Digital Dividends? -
PEAS - Making Meaningful Sense of Sensor Data and Information
(2020-02-29)Exploring convergence of ideas to transform data into meaningful information. -
A Portfolio Approach for Purchasing Systems: Impact of Switching Point
(2008-08-01)In operations management different ordering policies, such as, economic order quantity, lot for lot and periodic ordering, are used in various combinations without deeper considerations for the likely consequences on cash ... -
Potential for Improving Decision Support Catalysed by Semantic Interoperability Between Systems
(2008-07-31)Convergence of systems and intelligent automation may augment the ability of supply chain operations or healthcare networks to rapidly adapt to changes or respond, with minimal human intervention, under ideal conditions. ... -
Potential to Improve Forecasting Accuracy: Advances in Supply Chain Management
(2008-07-31)Forecasting is a necessity almost in any operation. However, the tools of forecasting are still primitive in view of the great strides made by research and the increasing abundance of data made possible by automatic ... -
A Purified Adenovirus 289-Amino-Acid ElA Protein Activates RNA Polymerase III Transcription In Vitro and Alters Transcription Factor TFIIIC
(American Society for Microbiology, 1991-10)We have previously demonstrated that a purified bacterially synthesized ElA 289-amino-acid protein is capable of stimulating transcription from the promoters of genes transcribed by RNA polymerase II in vitro (R. Spangler, ... -
Research Brief: A break-even hazard mitigation metric
(2017-01-12)CSHub researchers developed the Break Even Mitigation Percent (BEMP) to answer the question: “How much should be invested in mitigation for a particular building?” -
Research Brief: A Reaction-Diffusion Model to Determine Mesoscale Patterns in Cement Paste
(2018-08)Strength and toughness, two important aspects of the durability of concrete structures, are dramatically influenced by the material’s nanotexture, but the question of how the building blocks of cement paste organize ... -
Research Brief: A Resilience Assessment of Structures Using Molecular Dynamics
(2018-06)Between 1993-ˇ2012, more than 75% of catastrophic losses in the United States were caused by windstorms (1). The Congressional Budget Office estimated an average annual damage amounting to $28 billion (0.16 percent of GDP), ... -
Research Brief: Assessing Road Quality Using Crowdsourced Smartphone Measurements
(2020-07)As the demands on the nation’s roads increase, so too have road maintenance costs. To meet these challenges, agencies must vigilantly monitor road surface quality to properly apportion resources. Traditional methods of ... -
Research Brief: Can Passive House and Zero-energy Building Standards Promise a Low-carbon Future?
(2020-05)Passive house (PH) and zero-energy building (ZEB) standards aim to reduce the energy consumption and carbon footprints of buildings. The PH concept implies a low energy consumption achieved through passive technology such ... -
Research Brief: Capillary Stress During Cement Drying Shrinkage
(2018-06)Imagine a household sponge lying next to a kitchen sink. The sponge looks and feels different when it is wet versus when it is dry. When a sponge dries, it shrinks, curls and hardens due to suction forces (called “capillary ... -
Research Brief: Climate Change Mitigation Potential of Pavement Albedo
(2018-01)Albedo is the measure of how much solar energy is reflected by the Earth’s surface. Lighter color, or high-albedo, surfaces absorb less sunlight energy and reflect more shortwave radiation. Increasing pavement albedo has ... -
Research Brief: Community-Informed Building-Scale Resilience Assessment
(2020-02)It is widely known that natural hazards, like hurricanes, cause tremendous levels of damage and that hazard mitigation can significantly curb natural hazard-induced losses. However, necessary investments are still needed ... -
Research Brief: Concrete building design optimization for reduced life cycle costs and environmental impacts
(2018-04)Decisions made at early stages of the building design process can have a large influence on the environmental performance and financial costs of a building. One of the best ways to discover preferable designs is to analyze ... -
Research Brief: Creating Customized Fragility Curves for Resilient Building
(2018-11)Fragility curves, which are a statistical tool that represent the probability of exceeding a certain level of structural damage due to various forces applied to a building, are used to assess anticipated building performance. ... -
Research Brief: Evolving the C-S-H Packing Density at the Microscale
(2017-10-02)Cement paste is a complex multiphase material, roughly 50 percent of which, by volume, is composed of calcium-silicate-hydrates (C-S-H). The C-S-H phase, which lends the material its rigidity, appears to be a dispersion ... -
Research Brief: Examining Freeze-Thaw Damage at the Microscopic Scale
(2017-01-12)Researchers conducted both theoretical and numerical studies on the microscopic phenomena in cement paste pores to reveal the important roles that ions and electrolytes play in freeze-thaw damage. -
Research Brief: Generating Building-specific Fragility Curves
(2019-05)Fragility curves represent a structure’s likelihood of damage under a range of load levels—like those from natural hazards. They, therefore, help to set building code safety factors, resiliency ratings, and even insurance ... -
Research Brief: Generating Component-level Building-specific Fragility Curves
(2020-11)One of the most essential tools for representing the vulnerability of a structure is the fragility curve. By capturing the probability of damage at a given load level, fragility curves provide a way to express how a ...
