A Note on Practical Evaluation of Budgets in ECCO Version 4 Release 3

A Note on Practical Evaluation of Budgets in ECCO Version 4 Release 3 Piecuch, Christopher G. An outline and technical description is provided for evaluating tracer budgets (heat, salt, volume) offline using available monthly ECCOv4 model diagnostic output. Methods described here are intended for analysis of model output on its native spatial grid.

Inference and Regeneration of Programs that Manipulate Relational Databases

Inference and Regeneration of Programs that Manipulate Relational Databases Shen, Jiasi; Rinard, Martin We present a new technique that infers models of programs that manipulate relational databases. This technique generates test databases and input commands, runs the program, then observes the resulting outputs and updated databases to infer the model. Because the technique works only with the externally observable inputs, outputs, and databases, it can infer the behavior of programs written in arbitrary languages using arbitrary coding styles and patterns. We also present a technique for automatically regenerating an implementation of the program based on the inferred model. The regenerator can produce a translated implementation in a different language and systematically include relevant security and error checks. We present results that illustrate the use of the technique to eliminate SQL injection vulnerabilities and the translation of applications from Java and Ruby on Rails to Python.

Digital Transformation

Digital Transformation Datta, Shoumen Digital Economics is approaching and the "new economy" will need new rules, new changes and new thinking. Digital Transformation is a step toward Digital Economy. In this article, we haven't even scratched the surface of the imminent digital tsunami. Infrastructure and innovation must converge with tools and technologies, where systems must connect and communicate to meet the customer at the point of consumption. This will be an immense change which will turn paradoxes to paradigms. Please scroll down to download the pdf "Digital Transformation" Digital Transformation is a convergence of multiple tools, technologies and ideas. A few of these elements are discussed in this article/blog. Please download the pdf (please scroll down) and review Parts I through VII.

 Evaluation of the Albedo-induced Radiative Forcing and CO2 Equivalence Savings: A Case Study on Reflective Pavements in Four Selected U.S. Urban Areas

 Evaluation of the Albedo-induced Radiative Forcing and CO2 Equivalence Savings: A Case Study on Reflective Pavements in Four Selected U.S. Urban Areas Xu, Xin; Gregory, Jeremy; Kirchain, Randolph There is a growing interest in developing cool pavement strategies to mitigate pavement’s impact on the global warming in recent years. One of the mitigation strategies is by increasing the solar reflectance (or albedo) of the pavement surface, which directly contributes to global cooling by adjusting radiative forcing and potentially reduces the energy demand in the urban areas. In this paper, the radiative energy budgets in four urban areas are investigated based on the data derived from NASA satellite measurements. The radiative forcing (RF) due to the change of urban surface albedo as a result of reflective pavements is estimated using a simplified engineering model. The carbon dioxide (CO2) equivalence savings are also calculated with reference to the 100-year global warming potential of CO2. Results show that the implementation of reflective pavement has a great potential to reduce global warming. The CO2 reduction is significant in the urban areas but also affects the surrounding regions to some extent. In the end, we recommend using a climate model incorporating site-specific information that enables the visualization of the outputs through spatial maps. The results from this work would be useful for guiding the implementation of the cool pavement strategies.
