This paper describes the current state of RUgle, a system for classifying and indexing papers made available on the World Wide Web, in a domain-independent and universal manner. By building RUgle with the most relaxed restrictions possible on the formatting of the documents it can process, we hope to create a system that can combine the best features of(More)
A novel approach to life-cycle sustainability (impact) assessment and interpretation procedure on the basis of multiple criteria is developed in this paper for the comparison and evaluation of alternative road pavement designs. A case study reported in the literature, which compared pavement structures with virgin materials as well as industrial by-products(More)
In today's information age, government organizations and business enterprises are heavily relying on interconnected computer systems to manage a variety of public services including energy, transportation, water, etc. While this increased connectivity has many operational advantages benefitting the public, they have also become vulnerable to cyber attacks(More)

The bearing capacity and service life of a pavement is adversely affected by the presence of undrained water in the pavement layers. In cold climates like in Iowa, this problem is magnified further by the risk of frost damage when water is present. Therefore, well-performing subsurface drainage systems form an important aspect of pavement design by the Iowa(More)
The mission of the Institute for Transportation (InTrans) at Iowa State University is to develop and implement innovative methods, materials, and technologies for improving transportation efficiency, safety, reliability, and sustainability while improving the learning environment of students, faculty, and staff in transportation-related fields.

This paper focuses on the development of a new backcalculation method for concrete road structures based on a hybrid evolutionary global optimization algorithm, namely shuffled complex evolution (SCE). Evolutionary optimization algorithms are ideally suited for intrinsically multi-modal, non-convex, and discontinuous real-world problems such as pavement(More)
