Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

Strategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

Spray-Wall Impingement of Diesel-CNG Dual Fuel Jet using Schlieren Imaging Technique

MATEC Web of Conferences, 2014
Natural gas is a low cost fuel with high availability in nature. However, it cannot be used by itself in conventional diesel engines due to its low flame speed and high ignition temperature.

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Success and failure in foreign policy: Comparing Bob Hawke and Kevin Rudd's regional order‐building initiatives

Australian Journal of Public Administration, EarlyView.
Abstract Remarkably little is known about what factors drive success or failure in foreign policy. In part, this is because there is little fundamental agreement on what constitutes success or failure in this domain in the first place. This article engages with these shortcomings by comparing two similar regional order‐building initiatives overseen by ...
