Market novelty, competence-seeking and innovation networking

Studies of innovation networking have frequently been concerned with the occurrence of dyadic relationships and with their apparent impact on simple measures of firm-level innovation outputs. This paper takes a more detailed look by analyzing the connection between different types of innovation and forms of networking. Based on the market novelty of innovation outcomes and the extent to which innovation activities require new competences, four types of innovation are identified. It is proposed that these types correlate with various innovation network dimensions, including the volume of networks, the strength and content of ties, and the specificity of ties. Drawing on survey data of 594 innovations realized by Dutch small firms, it is observed that the requirement to access new competences for innovation correlates positively with the number of network partners involved. We also note more subtle connections between types of innovation and networking, including that novel innovation outputs correlate with using network partners as a source of inspiration, whilst new competences associate with networking for knowledge capital. In the latter case, these activities also draw on new and intended ties relatively often, i.e. network partners which are actively sought out for the specific contributions they may make to the innovation process. Finally, innovation which is simultaneously new-to-the market and requires new competences uses strong ties relatively often. Implications for innovation policy and practice are discussed.

TinyOS任务调度策略改进研究

针对无线传感器网络操作系统TinyOS任务调度策略的不足,该文提出了一种基于快速任务排队算法和动态优先级的FQ—IP任务调度策略。随着无线传感器技术的发展,TinyOS任务队列长度由8增加到了256,这使得任务队列排队算法显得愈发重要,该文提出了一种平均查找长度较小的排队算法,通过仿真测试表明,该算法可以在增加很小的计算开销下显著提高排队速度。同时,本文提出的策略通过定时的增加任务队列中任务的优先级的大小,使得低优先权任务能够在预订的时间范围内得到系统的调度,提高了系统的整体任务吞吐量。

A detailed behavioral analysis on consumer and customer changing behavior with respect to social networking sites

The main purpose of the study is to analyze the changing behavior of the customers on various products by conducting a customer review. The analysis is performed in three major steps such as, calculating customer review quality, calculating behavior quality of customer and review comparison. Behavioral analysis is a kind of science which helps to study and understand the behavior of human beings. It studies the factors that influence the behavior of living beings and non-living beings on a larger aspect. A special emphasis is placed on understanding, describing, predicting and changing behavior. Understanding the behavior of individuals is a tedious job to be performed and hence to evaluate the final result, the study used Chi-Square Method. As a tool, the paper employs customer reviews to gather primary and secondary data. These reviews inform, educate and explain the benefits of using customer reviews in gathering data. It is one of the best and easiest methods to formulate the score of comparison between customer's profile and their review. Findings of the study proved that depending on the customer's profile, the quality of the product varied. Furthermore, high rates of efficiency and accuracy is observed in gathering information on the products via customer's profile and review. Study authenticates an inclusive approach to explain factors manipulating consumer awareness, observation and sensitivity on product value. A depth analysis was carried out to identify the purchase decision, brand behavior, price influence the buying behavior and opinion of the customers. However, the factors such as high quality, social media networking sites and customer's profiles had a greater impact on buying behavior of the customers.     

Innovation And Inter-Firm Co-Operation: The Case Of The West Midlands

Drawing upon the innovative milieux and industrial districts literature, the paper provides substantial empirical evidence that firms have a greater chance of being innovative if they co-operate with other firms over innovation, albeit undertaking no investment in RLD. This is an important result especially for small firms. In particular, the paper focuses on inter-firm cwperation along the supply chain, using a swey of firms in the West Midlands to investi-gate co-operation over innovation between suppliers and buyers. A probit model is used to test the link between innovation performance and four innovation inputs: R&D expenditure, R&D personnel, networking with suppliers and networking with client firms.     

不理想的信道互易性对波束成形技术的影响…

在无线通信系统中,基站可以根据信道互易性使用波束成形（Beam Forming）技术提 升系统性能。信道互易性的准确程度对性能是有影响的,因此需要对其分析以指导系统设计 。对长期演进（LTE）系统的互易性进行建模,指出了终端发送天线和接收天线数目的不对 称性,以及基站信道估计的误差对信道互易性的影响。通过数值仿真验证了不理想的信道互 易性使波束成形性能受到损失,并为系统改进提出思路。其结论容易推广到其他应用波束成 形的无线通信系统。
