  • Over the course of roughly a year, after completing my first book, I resurrected an old pet project of building an autonomous submarine (referred to as the E-2 project) with certain fairly challenging functionality requirements. In the course of developing this idea, I spent many hours on the Internet and elsewhere, researching techniques for rapid development of various electromechanical control systems and platforms to run fairly complex signal-processing algorithms.

  • Soils are aggregates of mineral particles, and together with air and/or water in the void spaces, they form three-phase systems. A large portion of the earth’s surface is covered by soils, and they are widely used as construction and foundation materials. Soil mechanics is the branch of engineering that deals with the engineering properties of soils and their behavior under stress.

  • Bearings (both plain and rolling element) are used as important supporting elements for locating rotating components and confining their motion in desired direction. In order to ensure their operational reliability and desired life, these need to be properly designed/selected for an application more so because of ever increasing operational speeds. This requires the careful performance evaluation of different types of bearings considering aspects such as thermal stability, lubrication, contaminants in lubricants and controlling mechanism etc....

  • Organization scholars have long acknowledged that control processes are integral to the way in which organizations function. While control theory research spans many decades and draws on several rich traditions, theoretical limitations have kept it from generating consistent and interpretable empirical findings and from reaching consensus concerning the nature of key relationships.

  • This paper describes a system for managing: dialogue in a natural language interface. The proposed approach uses a dialogue manager as the overall control mechanism. The dialogue manager accesses domain independent resources for interpretation, generation and background system access. It also uses information from domain dependent knowledge sources, which are customized for various applications.
