Frequency shift of rotation-vibration band oscillation in carbon dioxide lase

True airspeed measured by airborne laser Doppler velocimeter

Velocimeter utilizing carbon dioxide laser measures true airspeed of aircraft. Results of flight tests indicate that clear-weather airspeeds can be measured with accuracy better than 0.1% at altitudes up to 3000 meters; measurements can be made at much greater altitudes in cloudy or turbid air

Cutting the Gordian knot? Assessing the outcomes of the March EU-India Summit. EPC Commentary, 8 April 2016

After a four-year suspension, the 13th EU-India Summit took place in Brussels on 30 March 2016. While several deep-rooted constraints could not be overcome, the Summit’s deliverables reflect a gradually changing and cautiously optimistic mood in the historically challenging interaction between Brussels and Delhi

Strategic information planning: Insights from an action research project in the financial services industry

The core purpose of strategic information planning (SIP) lies in identifying future directions for investments in information technology, information systems and information supply that will assist an organisation to realise its business goals. SIP is a critical challenge and major concern to both academics and practitioners, in particular consultants. While the latter have proposed a number of formal methodologies and principles of good practice, these are normative recommendations that are hardly justified through theoretical insight. In fact, SIP is yet to be well understood theoretically and requires more empirical support. This motivated us to carry out an in depth case study on SIP in a financial service company. The study aimed at improving the SIP practices in place and was conducted in an action research-like manner. This research report at hand presents the results of the study. We firstly describe the enterprise, its situation and the SIP practices in place. We then reflect upon the SIP process, its contingencies and its outcome in light of the current academic literature. This leads us to a number of theoretically informed suggestions that concern the improvement of SIP as well as the direction of the resulting information strategy. These suggestions have already been debated with senior IT executives from the case enterprise. This debate helped to confirm some theoretical propositions from literature while other recommendations were not agreed upon by the practitioners. Our findings from the study are finally framed to give a fresh impetus to future research and perhaps challenge some current wisdom

Incoherent "Slow and Fast Light"

We show experimentally that the effects of "slow and fast light" that are considered to be caused by spectral hole-burning under conditions of coherent population oscillations (CPO) can be universally observed with incoherent light fields on objects with the pure-intensity nonlinearity, when such an interpretation is inapplicable. As a light source, we used an incandescent lamp and as objects for study, a photochromic glass and a thermochromic coating. The response of the objects to intensity modulation of the incident light reproduced in all details the commonly accepted experimental evidences of the "light with a negative group velocity" and "ultraslow light". We come to conclusion that so far there are no experimental works providing evidence for real observation of the "CPO-based slow or fast light".Comment: 10 pages and 8 figure

A Literature Overview on Strategic Information Systems Planning

Strategic Information Systems Planning (SISP) has been among the highest ranked issues on management agendas for many years. As such, SISP should be a major concern for researchers as well. However, SISP does not play that important of a role in the academic discussion, at least in Germany. Leading German textbooks on Information Management devote only small sections to strategy themes. Moreover, the recommendations given for conducting SISP in these textbooks are mainly normative and hardly take international research findings into account. Taking this as a motivation, we conducted a comprehensive literature review of German and Anglo-American information systems journals. Our objective was to understand more fully what we know about SISP through international research. On the flip side, our research aims at identifying fields that are in urgent need for closer academic investigation so that individual speculations and normative recommendations might still substitute for valid research insights. Overall, we found a considerable amount of research conducted in the field of SISP that we organised in five broad thematic fields: Strategic IT impact, approaches to SISP, information systems strategy, and strategic alignment. We give a short overview of research conducted so far and seminal publications available in the research fields. Moreover, based on a sub-sample of our literature base, we compute statistics which indicate the intensity of the academic discussion in the different thematic fields over time. Our statistics show that most attention has been paid to the competitive use of IT. The IS strategy in contrast has only been of limited interest, though it is central to any strategic considerations in IS. Our survey also suggests that German speaking researchers have devoted relatively few efforts to SISP in comparison to their Anglo-American colleagues

Designing and executing digital strategies : completed research paper

The digital economy poses existential threats to — and game-changing opportunities for — companies that were successful in the pre-digital economy. What will distinguish those companies that successfully transform from those that become historical footnotes? This is the question a group of six researchers and consultants from Boston Consulting Group set out to examine. The team conducted in-depth interviews with senior executives at twenty-seven companies in different industries to explore the strategies and organizational initiatives they relied on to seize the opportunities associated with new, readily accessible digital technologies. This paper summarizes findings from this research and offers recommendations to business leaders responsible for digital business success

Diet reconstruction of wolves following a decline in Manitoba moose populations

Moose populations in southern Manitoba have declined. Although the primary cause of this decline is unclear, wolf predation is considered a main contributor because wolves have limited moose populations elsewhere. To help understand the role of wolf predation in limiting moose populations we reconstructed the proportional diet of wolves using stable isotope analysis and a Bayesian stable isotope mixing model (MixSIAR). We tested the assumptions of MixSIAR by running sensitivity analyses on trophic discrimination and prior information. We observed differences in wolf diet in areas where moose and deer coexist and are spatially separated, with changes both seasonally and annually. Our results suggest white-tailed deer were preyed on during winter, even in areas where deer are locally rare, suggesting prey catchability is more important than local prey density. Seasonal changes in prey accessibility strongly affect wolf predation rates, and manipulating alternative prey populations could mitigate predation impacts on moose.October 201

Probing IMF using nanodust measurements from inside Saturn's magnetosphere

We present a new concept of monitoring the interplanetary magnetic field (IMF) by using in situ measurements of nanodust stream particles in Saturn's magnetosphere. We show that the nanodust detection pattern obtained inside the magnetosphere resembles those observed in interplanetary space and is associated with the solar wind compression regions. Our dust dynamics model reproduces the observed nanodust dynamical properties as well as the detection pattern, suggesting that the ejected stream particles can reenter Saturn's magnetosphere at certain occasions due to the dynamical influence from the time‐varying IMF. This method provides information on the IMF direction and a rough estimation on the solar wind compression arrival time at Saturn. Such information can be useful for studies related to the solar wind‐magnetosphere interactions, especially when the solar wind parameters are not directly available. Key Points A new method to probe IMF with nanodust measurements inside the magnetosphere Under changing IMF, ejected nanoparticles can re‐enter Saturn‐s magnetosphere IMF direction and solar wind compression arrival time can be derivedPeer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/99078/1/grl50604.pd
