Atomic Clock and Atomic Magnetometer

Todaythe Battery-operated clocks (quartz clock) with frequency instabilities of 10-11 can be used for time interval up to a day, and the package is not larger than 1 cm3, it could be widely used in portable electronic devices. In certain military and civilian applications, such as global positioning systems (GPS) and synchronization of mobile communication and navigation networks which demands timing precision and stability, that cannot be achieved with low-power quartz crystal technology which takes time intervals of more than a few minutes. Atomic clocks can provide these stabilities. Atomic magnetometer has extremely high sensitivity so along with atomic clock atomic magnetometer can also sense extremely low magnetic field so this device can also use in biomedical as well as defense field

Design of Reconfigurable Crossbar Switch for BiNoC Router

this paper presents implementation of 10x10 reconfigurable crossbar switch (RCS) architecture for Dynamic Self-Reconfigurable BiNoC Architecture for Network On Chip. Its main purpose is to increase the performance, flexibility. This paper presents a VHDL based cycle accurate register transfer level model for evaluating the, Power and Area of reconfigurable cross bar switch in BiNoC architectures. We implemented a parameterized register transfer level design of reconfigurable crossbar switch (RCS) architecture. The design is parameterized on (i) size of packets, (ii) length and width of physical links, (iii) number, and depth of arbiters, and (iv) switching technique. The paper discusses in detail the architecture and characterization of the various reconfigurable crossbar switch (RCS) architecture components. The characterized values were integrated into the VHDL based RTL design to build the cycle accurate performance model. In this paper we show the result of simple 10x10 crossbar switch .The results include VHDL simulation of RCS on Xilinx ISE 13.1 software tool

Room Temperature Synthesized TiO2/Bi2Se3 Bilayer Thin Film by Simple Chemical Route: Study the Effect of Deposition Time of Bismuth Selenide on Physical Properties of Film

Simple chemical route namely Chemical Bath Deposition (CBD) has been successfully employed for deposition of Bismuth Selenide (Bi2Se3) nanoparticles on porous TiO2 at room temperature. The effect of deposition time of Bi2Se3 on structural, surface morphological and optical properties of TiO2/Bi2Se3 bilayer film has been systematically investigated. X-ray diffraction and energy dispersive X-ray spectra analysis was confirmed the Bi2Se3 nanoparticles are of effectively deposited on anatase TiO2 film. Field Emission Scanning Electron Microscopy (FESEM) images shows the TiO2 film uniformly covers by Bi2Se3 nanoparticles. Optical absorption spectrum is reflecting the considerable enhancement in absorption of visible light with increasing deposition time of Bi2Se3 on TiO2 thin film

Explicitly searching for useful inventions: dynamic relatedness and the costs of connecting versus synthesizing

Inventions combine technological features. When features are barely related, burdensomely broad knowledge is required to identify the situations that they share. When features are overly related, burdensomely broad knowledge is required to identify the situations that distinguish them. Thus, according to my first hypothesis, when features are moderately related, the costs of connecting and costs of synthesizing are cumulatively minimized, and the most useful inventions emerge. I also hypothesize that continued experimentation with a specific set of features is likely to lead to the discovery of decreasingly useful inventions; the earlier-identified connections reflect the more common consumer situations. Covering data from all industries, the empirical analysis provides broad support for the first hypothesis. Regressions to test the second hypothesis are inconclusive when examining industry types individually. Yet, this study represents an exploratory investigation, and future research should test refined hypotheses with more sophisticated data, such as that found in literature-based discovery research

A spill over effect of entrepreneurial orientation on technological innovativeness:an outlook of universities and research based spin offs

partially_open5siBy shifting towards Romer’s (Am Econ Rev 94:1002–1037, 1986) economy and so the spread of knowledge economy, universities started to adopt a collaborative approach with their entrepreneurial ecosystem. They turn out to be risk taker, autonomous, proactive, competitive, and innovative. In a nutshell, they are entrepreneurial oriented with the aim to generate new innovative ventures, known as research-based spin offs. Doubly, this has induced an improvement of technology transfer and the degree of entrepreneurship in the current knowledge economy. However there still is a paucity of studies on the spill over effect of entrepreneurial orientated universities and research-based spin off on technology transfer need to be more explored. Therefore, the article investigates the link between entrepreneurial orientation and such spill overs by offering an outlook of two universities and two research-based spin offs in the United Kingdom. The scope is to provide a deep view of technological innovativeness in a research context, entrepreneurial oriented. Our research suggests that entrepreneurial attitude has become an imperative to succeed in the context where British institutions currently operate. Entrepreneurship brings the necessary technological innovation to the university and its students, which results in better positioning of the university at national and international levels, with the subsequent impact on their ability to attract not only new students and academics but also funding to conduct their research.openScuotto, Veronica; Del Giudice, Manlio; Garcia-Perez, Alexeis; Orlando, Beatrice; Ciampi, FrancescoScuotto, Veronica; Del Giudice, Manlio; Garcia-Perez, Alexeis; Orlando, Beatrice; Ciampi, Francesc

The role of public funding in nanotechnology scientific production: Where Canada stands in comparison to the United States

This paper presents cross-country comparisons between Canada and the United States in terms of the impact of public grants and scientific collaborations on subsequent nanotechnology-related publications. In this study we present the varying involvement of academic researchers and government funding to capture the influence of funded research in order to help government agencies evaluate their efficiency in financing nanotechnology research. We analyze the measures of quantity and quality of research output using time-related econometric models and compare the results between nanotechnology scientists in Canada and the United States. The results reveal that both research grants and the position of researchers in co-publication networks have a positive influence on scientific output. Our findings demonstrate that research funding yields a significantly positive linear impact in Canada and a positive non-linear impact in the United States on the number of papers and in terms of the number of citations we observe a positive impact only in the US. Our research shows that the position of scientists in past scientific networks plays an important role in the quantity and quality of papers published by nanotechnology scientists

Untangling the effects of overexploration and overexploitation on organizational performance: The moderating role of environmental dynamism

Because a firm's optimal knowledge search behavior is determined by unique firm and industry conditions, organizational performance should be contingent oil the degree to which a firm's actual level of knowledge search deviates from the optimal level. It is thus hypothesized that deviation from the optimal search, in the form of either overexploitation or overexploration, is detrimental to organizational performance. Furthermore, the negative effect of search deviation oil organizational performance varies with environmental dynamism: that is, overexploitation is expected to become more harmful. whereas overexploration becomes less so with all increase in environmental dynamism. The empirical analyses yield results consistent with these arguments. Implications for research and practice are correspondingly discussed
