Study on the measurement system to evaluate the electrode temperature in super-high-pressure mercury lamps
publisherThoriated tungsten (ThO2-W) is popularly used for the electrodes in super-high pressure mercury lamps (SHPs) used in semi-conductor processing. However, ThO2-W is not desirable for the global environment because of its radioactivity. Therefore it would be very valuable to make a new non-radioactive material to replace ThO2-W as the electrode, and many research efforts have been attempted for this purpose. However, the materials which were researched till now could not improve upon ThO2-W lifetime when they were used as the electrode in the lamps. To evaluate the lamp life the electrode temperature and its distribution are very important, because the lamp life has the close relations with them. However to measure the electrode temperature of a SHP is very difficult because of its plasma radiation. We report the new optical method to evaluate the tungsten electrode temperature of SHPdepartmental bulletin pape
Optimal stomatal behaviour around the world
© 2015 Macmillan Publishers Limited. All rights reserved. Stomatal conductance (g s) is a key land-surface attribute as it links transpiration, the dominant component of global land evapotranspiration, and photosynthesis, the driving force of the global carbon cycle. Despite the pivotal role of g s in predictions of global water and carbon cycle changes, a global-scale database and an associated globally applicable model of g s that allow predictions of stomatal behaviour are lacking. Here, we present a database of globally distributed g s obtained in the field for a wide range of plant functional types (PFTs) and biomes. We find that stomatal behaviour differs among PFTs according to their marginal carbon cost of water use, as predicted by the theory underpinning the optimal stomatal model and the leaf and wood economics spectrum. We also demonstrate a global relationship with climate. These findings provide a robust theoretical framework for understanding and predicting the behaviour of g s across biomes and across PFTs that can be applied to regional, continental and global-scale modelling of ecosystem productivity, energy balance and ecohydrological processes in a future changing climate
Shock Events: The Impact of News Media and Communication Strategies on Listed Companies' Share Price
Academics studied the theory of a company’s communication when it is involved into a
crisis but they were less concerned about the impact of the communication on a listed
company’s share price, especially when it resulted from a shock event. There is a lack
of information about the role played by news media. The aim of this paper is to investigate if in cases of shock events (i) a company’s response strategy has a different effect
on shareholders, observing the effect on share prices, and (ii) how the news media can
affect the value change. Using the event study methodology, the Cumulative Abnormal
Return of companies’ share prices involved in shock events was calculated. Statistics
show a best effect of an accommodative response than a defensive strategy in cases of
scandals and product recalls. There is no valuable impact of company communication
in cases of incidents. With news media variable, the results show a worsening effect
with bad news and a mitigating effect with good news. It was proved that the impact
of a response strategy is surpassed by news media. When there is absolute certainty
of guilt for a given situation, it is more convenient for management to apologize, and
when there is no certainty, there was no substantial difference, because in the mind of
an investor the focus shifts to the event itself. The news media has been shown to have
a huge impact on investor perception, even more so than a company’s best responsestrateg

Memory Access Estimation of Filter Bank Implementation on Different DSP Architectures
A unified polyphase representation of analysis and synthesis filter banks is introduced in this paper, and then the efficient implementation on digital signal processors (DSP) is investigated. Especially, the number of memory accesses, power consumption, processing accuracy and the required instruction cycles are discussed. Firstly, a unified representation is given, and then two types of procedures, SIMO system-based and MISO system-based procedures, are shown, where SIMO and MISO are abbreviations for single-input/multiple-output and multiple-input/single-output, respectively. These procedures are compared to each other. It is shown that the number of data load in SIMO system-based procedure is a half of that in MISO system-based procedure for two-channel filter banks. The implementation of M-channel filter banks is also discussed.journal articl
