R&D strategy and Australian manufacturing industry: an empirical investigation of emphasis and effectivness

This research investigates the degree of emphasis placed by the Australian manufacturing industry on Research and Development (R&D) strategy as well as on other organisational strategies such as marketing, HRs (HR), technology, and operations at the functional level. The research extends further to investigate whether the emphasis on R&D strategy differs with contextual factors such as firm size, firm’s generic strategy, type of market, firm’s life cycle stage, etc. A mail survey was carried out to collect information from manufacturing firms across Australia. This was followed by an on-site interview of some of the senior managers of manufacturing firms from three Australian states: South Australia, Victoria and New South Wales.The study found that although the emphasis on R&D strategy has received a high priority in the past few years, it has not been as effective as the operations strategy and the technology strategy. The operations strategy has been accorded the highest importance in the past few years and this will continue in the future. The study also indicated that firms, which adopt a differentiation generic strategy, put more emphasis on R&D than the firms, which adopt cost leadership and focus generic strategies. The results did not indicate any evidence of a relationship between firm size and the R&D strategy although large firms are found to put more emphasis on operations and marketing strategies. Relatively higher emphasis was placed on the R&D strategy by businesses: at the growth stage; involved in the manufacture of consumer goods as opposed to industrial goods; involved in exports with a higher sales growth in export markets; and having a higher growth rate relative to their industry.     

基于MATLAB的风能自校正自调整PID模糊控制器仿真研究

为了提高风力发电系统综合系统性能,在传统风力发电技术的基础上,对变速风力发电机组的自校正自调整PID模糊控制进行了详细的分析和研究,从而利用模糊控制和PID控制相结合的技术,取得了很好的效果。从MATLAB仿真结果看出系统精度及效率很高而稳态误差较小,鲁棒性较好。     

三峡三期工程主坝大体积混凝土内部温度控制

三峡右岸三期工程施工中,为了有效控制坝体大体积混凝土内部温升,采取了高温季节使用预冷混凝土浇筑、控制混凝土出机口温度及浇筑温度、对混凝土内部人工通水进行初冷、中冷和后冷等措施。三峡三期工程大坝混凝土内部温度没有出现超标现象,混凝土温控工作取得了良好的效果。     

利用黄河泥沙加固下游大堤

黄河是一条举世闻名的多泥沙河流，善淤、善决、善徒给沿河人民带来对过深重灾难，防洪问题一直是国家的心腹之患。泥沙问题是黄河防洪问题的症结所在。在总结固大堤经验的基础，进行挖河疏浚，淤筑“相对地下河”，已作为黄河治理的一项重大决策付诸实施。     

三峡水库减淤增容调度方式研究——多汛限水位调度方案

本文建议在汛期中小流量时（Q<35000m3/s），将坝前水位维持在148～151m；出现汛情且流量更较大后，将坝前水位降低到143m；入库流量大于35000m3/s且短期预报将出现大于十年一遇洪水时，预泄洪水到135m.按这一调度，汛期约80％时间可以维持在较高水位，一般洪水期。汛限水位143m不影响坝区通航，135m水位迎洪可大量增加防洪库客。到100年后可减淤30亿m3，增加防洪库容约40亿m3.变动回水区减淤40%，优化了坝区水沙搭配，可改善通航条件。降低库区洪水位，缓解防洪与移民的矛盾。可对发电带来较大好处：提高发电效益，减少粗沙过机。初期水库排沙比大于原方案，可减轻下游冲刷。同时，可减小三峡汛初泄水与鄱阳湖防洪的矛盾。     

鄱阳湖控制浅说

该控制工程主要效益是改变鄱阳湖“夏水冬陆”的现状，成为祖国名符其实的第一大淡水湖，水面与避署胜地庐山和历史名城南昌、景德镇等相连，改善沿湖环境，发展航运，增加水产，开发利用丰富的水资源和旅游资源使之与杭州西湖、瑞士日内瓦湖等并列为世界名湖。

Relationship of Planning and Control Systems with Strategic Choices: A Closer Look

The study finds that relative to others, firms pursuing the Prospector-like strategy (high innovation) have lower financial results uncertainty, a more long-term orientation for decision making, and more decentralized control. As well, the tightness of budgetary control is found to be negatively correlated with financial results uncertainty. Thus, we are able to reproduce in our study the result that Prospector type firms have tighter budgetary control, which many have found puzzling previously, and point to the relation between strategy and financial results uncertainty as an explanation for the result.Based on a sample of large firms in Singapore, the study also finds the impact of the 1997–1998 Asian crisis is correlated with the intensity with which the Prospector-like strategy was pursued.     

长江螺山站高水位流量关系和城陵矶（莲花塘）控制水位的研究

螺山站高水位流量关系是确定长江城陵矶（莲花糖）控制水位的基本依据，从基本的河道水力学规律出发，考虑涨落率修正、瞬时比降修正，计算各时段点的代表性比降，和相应糙率，求出均值，根据断面资料，得出高水位的稳定流曲线，并以各日流量转化的稳定流点，进行验证，精度很好，分析了河段区间流量对螺山站稳定流量的影响。阐明了螺山站稳定流量的变化情况和趋势，推求了各次大洪水的超额洪量，计算出莲花糖以上的总入流，根据现今的湖区及槽蓄容积进行洪水演进，计算1954年特大洪水的超额洪量，并分析节三峡水库拦洪后对长江中下游超额水量的影响；对莲花塘不同防洪控制水位进行了技术经济分析和评价，提出了抬高控制水位的具体建议。
