A design methodology to enable sampling PLLs to synthesise fractional-N frequencies

A novel design methodology is proposed to enable sampling phase-locked loops (SPLL) to synthesise fractional-N frequencies. To date, SPLL can only generate integer-N frequencies. The benefit is that the proposed SPLL has the advantages of both fractional-N phase-locked loop (FN-PLL) and SPLL, such as the faster frequency switching, a smaller phase jump and a larger loop gain. Since the frequency divider can be omitted in SPLL, the associated phase noise, power and hardware consumption can be ignored. Also, the design work is simplified, since the complex multi-phase frequency divider is not needed in the proposed fractional-N sampling phase-locked loop (FN-SPLL)

VLSI Revisited - Revival in Japan

This paper describes the abundance of semiconductor consortia that have come into existence in Japan since the mid-1990s. They clearly reflect the ambition of the government - through its reorganized ministry METI and company initiatives - to regain some of the industrial and technological leadership that Japan has lost. The consortia landscape is very different in Japan compared with EU and the US. Outside Japan the universities play a much bigger and very important role. In Europe there has emerged close collaboration, among national government agencies, companies and the EU Commission in supporting the IT sector with considerable attention to semiconductor technologies. Another major difference, and possibly the most important one, is the fact that US and EU consortia include and mix partners from different areas of the semiconductor landscape including wafer makers, material suppliers, equipment producers and integrated device makers.semiconductors, Hitachi, Sony, Toshiba, Elpida, Renesas, Sematech, VLSI, JESSI, MEDEA, ASPLA, MIRAI, innovation system

Territorial innovation dynamics and integration of SMEs into the collaborative innovation projects of French competitiveness poles: the underlying mechanisms

Geographical clusters are nowadays considered as a relevant factor for competitiveness, thanks to their innovative capabilities. In this context, public policies based on this approach are flourishing all over the world. The French “Pole of competitiveness” (PoC) policy (Politique des pôles de compétitivité) is one of these initiatives. It is the new French industrial policy aiming at reinforcing the specializations of the economy and the attractiveness of territories by fostering the development of R&D projects, bringing together multinationals, universities, and particularly Small-Middle-Sized-Enterprises (SMEs). Precisely, significant research suggests that in order to innovate SMEs need to cooperate and they are also vital for the functioning, and survival of innovative milieux. Consequently, their integration is a key issue for French PoC' success. However, the call for projects shows that despite their efforts, French Poles of Competitiveness are not totally successful: a gap remains especially between the massive financial investments helping SMEs innovate and the expected results. Yet, this issue is only analysed by focusing on intrinsic weaknesses of SMEs' management or on the complexities of existing support programmes supporting SMEs' innovation. This is insufficient. Innovation dynamics are different from a cluster to another and many failures of innovation policies come from the lack of identification of these specificities. Therefore, this paper aims are threefold: it aims at introducing the French PoC, indeed, the French PoC policy is the main new policy gathering all the nation's innovation programmes. But few papers are explaining how they work. It aims at identifying the territorial innovation dynamics within PoC and how they work, and then combine this analysis with the intrinsic features of SMEs management, to better understand how they get involved in these dynamics. It finally aims at presenting the preliminary results of the first stage of research: the analysis of a specific French PoC, the “Secured Communicating Solutions”(SCS) PoC as well as the further research questions they raise for the next stage of research.clusters, interaction, knowledge management, SMEs

A Multi-hop Topology Control Based on Inter-node Range Measurement for Wireless Sensor Networks Node Localization

In centralized range-based localization techniques, sufficiency of inter-node range information received by the base station strongly affects node position estimation results. Successful data aggregation is influenced by link stability of each connection of routes, especially in a multi-hop topology model. In general, measuring the inter-node range is only performed for position determination purposes. This research introduces the use of inter-node range measurement information for link selection in a multi-hop route composition in order to increase the rate of data aggregation. Due to irregularity problems of wireless media, two areas of node communication have been considered. The regular communication area is the area in which other nodes are able to perform symmetrical communication to the node without failure. The irregular area is the area in which other nodes are seldom able to communicate. Due to its instability, some existing methods tried to avoid the irregular area completely. The proposed method, named Virtual Boundaries (VBs) prioritizes these areas. The regular communication area’s nodes have high priority to be selected as link vertices; however, when there is no link candidate inside this area, nodes within the irregular area will be selected with respect to their range to the parent node. This technique resulted in a more robust multi-hop topology that can reduce isolated node numbers and increase the percentage of data collected by the base station accordingly

Effects of environmental colour on mood: a wearable life colour capture device

Colour is everywhere in our daily lives and impacts things like our mood, yet we rarely take notice of it. One method of capturing and analysing the predominant colours that we encounter is through visual lifelogging devices such as the SenseCam. However an issue related to these devices is the privacy concerns of capturing image level detail. Therefore in this work we demonstrate a hardware prototype wearable camera that captures only one pixel - of the dominant colour prevelant in front of the user, thus circumnavigating the privacy concerns raised in relation to lifelogging. To simulate whether the capture of dominant colour would be sufficient we report on a simulation carried out on 1.2 million SenseCam images captured by a group of 20 individuals. We compare the dominant colours that different groups of people are exposed to and show that useful inferences can be made from this data. We believe our prototype may be valuable in future experiments to capture colour correlated associated with an individual's mood

An Inquiry into the Status and Nature of University-Industry Research Collaborations in Japan and Korea

University-industry collaboration (UIC) has become an increasingly frequent innovation strategy, especially in the Western hemisphere. But we know much less about such research collaborations in East Asia. This study explores and contrasts the current nature and status of UICs in Japan and Korea focusing on factors that facilitate the development and management of such research linkages. The findings indicate that UICs are path dependent, i.e. firms benefit from their experience with previous projects when collaborating with universities. At the same time, cultural factors appear to result in significant differences in the organization of UICs in Japan and Korea.University-industry collaboration, R&D collaboration, International comparison, Japan, Korea
