Vehicle classification and axle load data are required for the structural design of new and rehabilitated flexible and rigid pavements with the new Mechanistic-Empirical Pavement Design Guide (MEPDG) developed under NCHRP Project 1-37A. The axle load spectra are determined from traffic data collected at weigh-in-motion (WIM) stations, and vehicle count and class data are recorded by vehicle classification stations. Some preliminary results are presented for an extensive traffic data-processing effort conducted to develop traffic inputs required by the MEPDG to design pavements in New York State. The data collected by classification and WIM sites from 2004 to 2009 were processed with the TrafLoad software developed in NCHRP Project 1-39. The discussion focuses on the variability of the major traffic input variables required by the MEPDG, as obtained from data collected in New York State, and on the differences between the data obtained from individual stations, state average values, and the default values recommended by the MEPDG, where applicable. The effect of variability of the major traffic input variables on the performance predicted by the MEPDG for a typical flexible pavement structure is also discussed.

Supported by a National Science Foundation, Pan-American Advanced Studies Institute (PASI) grant and the Smithsonian Institute, two expeditions were made by teams of multidisciplinary researchers to the Andes Mountains of Peru to study the design and construction methods used to build the great Inca Road. The objectives of the study were to identify sustainable engineering practices used by the Inca, determine which practices can apply to modern design and construction, and share findings with visitors at the National Museum of the American Indian and others throughout the world through live interactive satellite broadcasts. This paper focuses on the technologies that were used to accomplish the broadcasts and used to support the engineering and construction analysis of the Inca Road. Each technology used on these expeditions provided a unique opportunity to learn about the road and disseminate findings with others. The technologies utilized included communication equipment (e.g., satellite router and dish, Wi-Fi, and mobile portable video equipment), location and mapping technologies [e.g., geographic information system (GIS) and global positioning system (GPS)], photogrammetric techniques for three-dimensional modeling, laser range finding for precision measurement of the road features, and ground-penetrating radar (GPR) for use in nondestructive testing and evaluation of subsurface conditions. The technologies are explained in this paper along with the challenges of implementing them in such harsh and extreme conditions. In addition, some of the more salient engineering and construction discoveries are included. This information can be useful for others who are interested in implementing a similar approach for studying ancient civil infrastructure in other remote locations. © 2013 American Society of Civil Engineers.

Efforts involving multiple institutions, whether aimed at sharing resources, at product development or production, at research, or in other directions, often rely on effective knowledge generation and knowledge management. However, there are inherent new difficulties in knowledge management for such inter-institutional collaborations, arising from the need to standardize and synthesize knowledge from multiple sources, and from the need to provide adequate protections for confidential and proprietary information.

Collaboration between organizations raises significant knowledge management issues, especially in software development of complex projects, in which both product and process are themselves knowledge. While research has examined direct, explicit flows of knowledge within project aspects, or forward between aspects, there is less investigation of the need and support for backward, implicit or emergent flows.

As software development becomes more collaborative, business and technical processes of software engineering and their management need to accommodate and support collaboration. In this paper we briefly survey key concerns, known challenges, and potential alternative solutions. We draw on lessons learned from software process models, organizational behaviour and knowledge management and their relevance to collaborative software development. We suggest elements of the solution to the problem of managing business and technical processes with software development in inter-organizational context. © 2011 Research Institute for Ope.

In this paper, we study the communication overhead of gossip-based information dissemination algorithms. Among basic variants of gossip algorithm push is most efficient in the early rounds while, in contrast, pull becomes more efficient in the later rounds. Therefore, a cost-efficient gossip algorithm needs to combine the advantages of push and pull algorithms. One possible approach is to begin with push algorithm and then at some point switch to pull algorithm. We analyze the effect of transition round from push to pull on the communication cost of gossip algorithm. We use simple deterministic difference equations to approximately model the message propagation throughout the network for both push and pull algorithms and derive closed form solution for pull model. We then present our First-Push-Then-Pull (FPTP) gossip algorithm and obtain the optimum round to transition from push to pull. We show that, in a fully connected network, normalized communication cost is minimized to approximately a constant (≈2.6 transmissions/message/node) when the transition round is Round(logN). Furthermore, we extend our results to networks with limited connectivity/cooperation and show that although the communication overhead increases moderately as a function of connection probability, it still remains approximately constant. To validate our results we test our algorithm in mobile ad-hoc network (MANET) environment using random-waypoint mobility model and show that the simulation results closely follow our analysis. © 2012 IEEE.

There is a need for metrics for inter-organizational collaborative software development projects, encompassing management and technical concerns. In particular, metrics are needed that are aimed at the collaborative aspect itself, such as readiness for collaboration, the quality and or the costs and benefits of collaboration in a specific ongoing project. We suggest questions and directions for such metrics, spanning the full lifespan of a collaborative project, from considering the suitability of collaboration through evaluating ongoing projects to final evaluation of the collaboration.

Effective coordination and collaboration are key success factors in management of inter-organisational alliances, although questions related to best practices remain unanswered. Few studies have identified communication, effective information sharing and knowledge extraction as integral components of inter-organisational collaboration. This research focuses on the role and effectiveness of Information Processing (IP), as well as information utilisation across organisational boundaries. Proposed is a set of factors in three categories related to organisational background, contingency process and information technology processing capacity to investigate if higher levels of these factors will result in higher levels of IP, and if this will result in higher levels of Software Development (SD) effectiveness. © 2011 Inderscience Enterprises Ltd.

Inter-organisational Collaborative Software Development (CSD), like other inter-organisational collaborative efforts that span national, language and cultural boundaries, raises significant challenges and risks. Its study offers useful insight with regard to the more complex, collaborative, and interdependent operational environment, where new risks arise and interfere with software projects even when all traditional risks are well controlled. In this paper, we outline a collaborative risk management framework, and focus on a set of governing policies and management contingency processes required to support the framework and to manage the interactions with other critical project activities and goals. © 2011 Inderscience Enterprises Ltd.

It is widely accepted that coordination of planning, production, and delivery processes is more effective and efficient when done at supply chain level than at individual firm level. To make supply chain level coordination possible, companies need to exchange information timely and seamlessly. This requires tight integration of systems among supply chain entities. Collaborative Software Development (CSD) is critical for successful system development for supply chain coordination and management. Challenges derive from the need to integrate various heterogeneous systems, facilitate proper information exchange and communication, and define organisational control and management. This paper examines emerging issues and obstacles in CSD in SCM contexts. © 2011 Inderscience Enterprises Ltd.
