东营凹陷三维地震采集评述

通过对东营凹陷内已采集的67块三维地震资料的简要分析,回顾了其三维地震勘探的历程,对三维地震采集进行了后评估,论述了采集技术的发展与勘探需求的关系;并对凹陷内两块高精度三维二次采集的资料进行对比分析。最后,对第二次高精度三维地震采集提出几点建议。     

Applying DNA analysis method to training data mining for FastADR response model of air‐conditioning power consumption

In the future, smart grid fast automated demand response (FastADR) applications for air‐conditioning facilities may require statistical models to determine changes in power consumption. In this paper, we report an innovative method for extracting step‐like responses in time‐series data obtained during normal operations, that is, without requiring any manipulation of the facilities. The new method was inspired by the DNA analysis computation algorithm called the Breakpoint method. © 2016 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.

Narrowing the gap: Practical strategies for increasing whole‐grain consumption

Overcoming consumer confusion and doubt regarding nutrition recommendations is key to communicating the message to increase whole‐grain foods in the diet. Nutrition communicators may do that more successfully by using four tactics to fashion messages about whole grains: (1) present a positive message; (2) keep it short and simple; (3) keep the message practical and flexible; (4) speak with a united voice. The quantitative recommendation to eat at least three servings of whole‐grain foods daily also must be integrated into national nutrition documents, such as Healthy People 2000, Dietary Guidelines for Americans, the Food Guide Pyramid, Nutrition Recommendations for Canadians, and Canada's Food Guide to Healthy Eating, if we are to be truly successful in communicating the need to increase whole‐grain consumption.     

中国工业发展对水资源的需求

以统计数据为依据，对我国工业发展及其用水变化过程进行了分析，并在国内外工业用水分析比较的基础上，对我国未来工业需水增长态势进行了趋势展望，同时分流域预测了我国工业经济的未来发展格局及其需水量，提出了保障我国工业经济持续发展的水资源利用对策与措施。笔者认为，在加强节水、科学用水的前提下，我国水资源利用完全可以保障我国工业化的发展。     

The demand for gasoline: Further evidence

Sufficient time must be allowed to elapse to assess fully the response of gasoline demand to price changes. Hitherto, empirical work on the subject has generally not examined the period beyond 1975; moreover, the extant time-series studies concentrate almost exclusively on the USA. This study extends both the observation period and the country coverage. A vehicle stock-adjustment model is estimated via its reduced form without explicit consideration of the vehicle stock itself. However, the estimation procedure incorporates the structure by way of constraints on the parameters. Cross-section analysis offers additional evidence concerning the truly long-run price elasticity. The results suggest that there is no need to resort to elaborate models to explain adequately gasoline demand. Gasoline demand exhibits a long-run price elasticity near unity with time lags exceeding six years, while there is tentative evidence that the duration of these lags is not fixed.     

市场经济条件下油气需求预测集成系统研究

在市场经济条件下开展油气需求预测活动，无论对于宏观能源管理还是对于油气生产企业来讲都是至关重要的，因此，对油气需求预测方法进行了讨论，首先从预测的经济环境，预测方法与预测数据等方面，指出了现存的一些预测方法和结论的不足之处；其次提出了油气需求预测集成系统的概念，分析了该系统的性质，说明了与传统预测模式的不同之处；最后阐述了建立油气需求集成系统的途径。     

Design and installation of solar photovoltaic powered water pumping system at Usmanu Danfodiyo University, Sokoto

The paper presents the outcome of the powering of a conventional a.c. type water pump by photovoltaic (pv) solar modules which were 28 in number connected 7 in series giving a total of 4 parallel strings. An assesment of the system, which provides water to the University Mechanical Workshop and a nearby village, shows that the system has been operating continously since October 1993 and on average 20 m³ of water is pumped daily at average solar radiation level of 5kWh/m²/day.     

Alternatives for meeting peak cold storage demand in a New Zealand seasonal industry

Seasonal industries producing products which require cold storage are always faced with the problem of obtaining sufficient storage capacity to meet the peak demand. This paper examines the storage demand pattern of the meat export industry in New Zealand and looks at the economics of building and operating on-site stores to meet peak demand compared with the costs of additional transportation to and hiring of off-site storage space. The concept of temporary stores using non-conventional structures (air supported, air inflated and steel frame supported) is also examined.
