With technology convergence increasing, manufacturers are facing a bewildering array of diverse regulations that they need to comply with for their products to be successful. The European Commission's Convergence Green Paper discusses technology convergence in relation to its relevance to the Information Society, and therefore confines itself to consideration of telecommunications, media and IT sectors. Within these sectors it defines technology convergence as the ability of different network platforms to carry essentially similar kinds of services, or the coming together of services in consumer devices such as the telephone, television and personal computer. Because these are the areas which most affect everyday life, as well as a large proportion of product designers, they are the primary consideration of this article, but technology convergence presents manufacturers of all sorts of consumer and industrial equipments with a difficult challenge in bringing new products to market, especially a global market. 相似文献

人类基因组序列的破译提供人类基因最基本的结构信息,同时一些功能性基因组技术的出现,如基因芯片技术、微阵列比较基因组杂交技术、蛋白质组学技术的产生,人们越来越渴望从组织切片上,获取某一特定的同类细胞,从而对这些或者个细胞内癌基因、抑癌基因、侵袭转移相关蛋白、信号转导蛋白、细胞增殖和分化相关蛋白等进行研究,但以往各种技术所获得的细胞都不可能是单一同类细胞群。显微切割(microdissection)技术〔1,2〕是自20世纪90年代初出现的新技术,能从组织切片上切割下几百个、几十个同类细胞。利用显微切割技术可以将组织内单一细胞群切割下来进行研究,避免间质细胞及一些炎症细胞造成背景“污染”,从而使得研究结果准确,避免假阳性和假阴性结果出现。 相似文献

The purpose of this study is to develop the decision model to help decision makers with their technology selection. Evaluation and selection of a new technology is a multi-criteria decision-making process encompassing various tangible and intangible factors. Thus, these factors should be identified for inclusion in the evaluation process. A thorough analysis of the impact, both positive and negative, of such factors on the organization is also required in the evaluation technique. Therefore, the first step in the development of a decision model for evaluation of technology alternatives is the identification of the pertinent factors. To accomplish this, both risks and benefits of implementing a new technology are identified for inclusion in the evaluation process. Once pertinent risks and benefits are identified, a mechanism for analysis of these factors is developed. Since these factors can be objective and subjective, a hybrid approach that applies to both quantitative and qualitative factors is used in the development of the model. Taguchi loss function is used to measure performance of each technology candidate with respect to the risk and benefit categories. Appropriate Taguchi loss functions are formulated based on the target value and the specification limits set by the decision maker. These loss functions are then used to calculate Taguchi loss scores for each technology alternative. Analytic hierarchy process (AHP) is used to determine the relative importance of the risks and benefits to the decision maker. The weighted loss scores are calculated for each technology alternative by using the relative importance as the weights. The composite weighted loss scores are then calculated and used for ranking of the technology alternatives. The technology with the smallest composite loss score is recommended for adoption. The proposed model provides guidelines for managers to make an informed decision regarding technology selection. In addition, combining Taguchi loss function and AHP provides a novel approach for ranking of the potential technology alternatives for implementation purposes. 相似文献
