Future development programs
A company program was planned which has a main drive to develop those emission reduction concepts that have the promise of earliest success. These programs were proposed in an attempt to enhance existing engine systems, exploiting their potential for emission reduction as far as is compatible with retaining the well established features in them that are well understood and in current production. The intended programs identified in the area of new concepts were: (1) upgrading the TCM fuel system, (2) evaluation of accelerator pump, (3) reduced cooling requirement, and (4) variable spark timing
Managing innovation in English language education, state of the art review.
Innovation in English language education (ELE) has become a major ‘growth area’ in recent years. At the same time, an ELE innovation management literature has also developed, based on insights from innovation theory and their application, both from outside and within ELE, and concerned with attempting to critically evaluate and inform ELE innovation practice. Thus, using a well-established three-part framework for distinguishing the main stages involved in innovation project management, this review describes and discusses the main features of this body of work. After defining terms and clarifying its scope, it considers what is said about the innovation ‘initiation’ phase, in terms of innovation causes, characteristics and contexts. It then examines conceptualisations of the innovation ‘implementation’ stage, by distinguishing main overall approaches, frameworks for identifying and configuring roles, underlying psychological processes, and the use of evaluation techniques. Lastly, the literature relating to innovation ‘institutionalisation’ stage is analysed. The article concludes by identifying overall trends and areas for further development. In particular, it is argued that ELE innovation work needs to become more informed by many of the concepts and procedures which the ELE innovation management literature contains
Low Regularity Ray Tracing for Wave Equations with Gaussian beams
We prove observability estimates for oscillatory Cauchy data modulo a small
kernel for -dimensional wave equations with space and time dependent
and coefficients using Gaussian beams. We assume the domains and
observability regions are in , and the GCC applies. This work
generalizes previous observability estimates to higher dimensions and time
dependent coefficients. The construction for the Gaussian beamlets solving
wave equations represents an improvement and simplification over
Waters (2011).Comment: this version shortens and changes the previous construction and
contains an extension to space time dependent coefficient
