Detection of liquid-liquid interface is critical in solvent extraction equipment/contactors typically used in petroleum and hydrometallurgical industries. An instrumentation system, comprising of a self-calibrating ultrasonic sensor and a novel signal processing algorithm is reported. It can be used to estimate location of liquid-liquid interface along with speed of sound in both the liquids without any manual/user intervention. The algorithm involves use of discrete wavelet transform and matched filter. The system has been tested at laboratory scale under wide range of industrially relevant conditions. The system works for any pair of liquid without apriori knowledge of their acoustic characteristics, is insensitive to changes in temperature and/or compositions. It also works for dirty interfaces contaminated with particulate matter or emulsion. The above mentioned features truly impart the sensor system “deploy-and-forget” capabilities. The range, accuracy and resolution of the system, with respect to interface location, are 40–200 mm, 0.45% FS (Full-scale) and less than 1 mm, respectively.

The commercialization of technological innovation, which is key to entrepreneurial success, represents a combination of several entrepreneurial activities. Building on research in management, strategy, entrepreneurship, and economics, this research summarizes 194 articles from 62 journals, categorizing them into six broad entrepreneurial activity themes: sources of innovations, types of innovation, market entry competence and feasibility, protection, development, and deployment. This review and synthesis suggest a framework of commercialization and an agenda for future research along with recommendations and guidance for future research. The proposed agenda provides topics and research questions for research, as well as related recommendations regarding the study and practice of the commercialization of innovation.

We investigate the effects of focal firm knowledge intensity and uncertainty on inter-organizational trust and subsequent performance of small and medium size enterprises (SMEs). We integrate the trust literature with transaction cost literature as both of these offer partial explanations of the dynamics of inter-organizational trust in the context of an SME. We propose that knowledge intensity of the focal firm will have a positive relationship while uncertainty will have a negative relationship with inter-organizational trust in an exchange relationship. Further, we propose a positive relationship between trust and SME performance, which will be contingent on the level of external and internal uncertainty faced by the focal firm. Empirical evidence, based on the survey data of 565 German SMEs, mostly supports our arguments.
