The Discount to NAV of distressed German open-ended real estate funds
No full textThe German open-ended real estate fund industry was strongly hit by massive out flows in the course of the global financial crisis. In total, 18 public and institutional real estate funds had to stop the redemption of shares and were ultimately forced to liquidate their portfolios. Investors of these funds either have to await the stepwise liquidation of the funds' assets, which can take up to several years, or they can opt to sell their shares on the secondary market, often at a substantial discount to the Net Asset Value (NAV Spread). This paper attempts to explain the NAV Spread of distressed German public open-ended real estate funds. The unique monthly dataset contains fund specifics and macroeconomic indicators for the entire relevant period. Fundamentals like the leverage ratio and the liquidity ratio as well as industry-wide spillover effects from fund closures affect the NAV Spread. Moreover, we detect a considerably influence of macroeconomic uncertainty explaining the discount to NAV
Detecting differences between versions of Microsoft Dynamics NAV
No full textMicrosoft Dynamics NAV is an Enterprise Resource Planning system developed by Microsoft. NAV is customized to specific countries, industrial segments, and enterprises by software developers both from the Microsoft Cooperation and from a chain of independent partners.In NAV, customizations are implemented as source-code modifications. This customization mechanism is flexible, since customizations are not limited to specific models imposed by implementation language or external customization tools. Therefore, it directly contributes to maintaining and enlarging the set of countries, industrial segments, and enterprises reachable by NAV. However, the customization mechanism of NAV imposes a significant cost of migrating customizations between different versions of the core product.This reports describes tools developed with the purpose of detecting and characterizing customizations applied to Microsoft Dynamics NAV. We propose to detect customizations by identifying differences between original and customized versions of NAV. In order to enable analyzes of the detected customizations, we furthermore suggest that differences are represented as hierarchically structured tree alignments .The primary components of the tools are an implementation of by Jiang, Wang, and Zhang’s algorithm for computing tree alignments and its use in a tool that detects changes between two different version of Microsoft Dynamics NAV. The report serves both as a manual to using the tools and to modifying the tools. The tools described in this report were implemented by the author between August 2008 and July 2009 when he was associated with a research project on Evolvable Software Products involving the IT University of Copenhagen and Microsoft Dynamics, Vedbæk, Denmark

Application of Electro-Active Materials to a Coaxial-Rotor NAV
No full textA new Nano Air Vehicle (NAV) configuration based on a coaxial nano rotor has been studied by ISAE. The coaxial rotor provides the thrust necessary for hovering and low speed translation flight. The major design challenge for rotary-wing NAVs is related to the difficulty of miniaturizing complex mechanisms such as a rotor cyclic pitch swashplate commonly used for controlling helicopters. The use of actuators made of smart materials is believed to allow for controlling rotary-wing NAVs in a much simpler and lighter way. The multidisciplinary subject of this complete system is separated into few parts. The studies of each subject are individually conducted before integrated in the future in order to optimize the global system. Those studies which are being carried out are shortly described in this paper

Reduced Navigation Data: Optimizing the Galileo I/NAV Navigation Message for a Fast First Fix
No full textThis research focuses on GNSS users interested in a faster position fix in a situation where the receiver holds limited data. This occurs when turning on a mobile phone or sport watch to use a location-based service, driving out of a parking garage with a navigational device or activating a search & rescue beacon. In these cases, users care more about directly setting a certain action into motion, than waiting until a sub-meter level of accuracy is acquired. For this purpose, we aim to decrease the time to first fix (TTFF) of a receiver at the expense of position accuracy by focusing on its most dominant component: the time to read the first fix data, i.e. the TTFFD. In turn, the TTFFD is decreased by reducing the size of the clock correction and ephemeris data (CED) and integrating this reduced set into the existing Galileo I/NAV message while maintaining backward compatibility. Three reduction strategies are presented to reduce the size of the CED. First, the expression of the CED parameters relative to the matching almanac parameters, which requires downloading the most recent almanac. Second, the absorption of the clock and ephemeris time reference into related parameters by leveraging redundancies in the user algorithm. Third, the truncation of the CED parameters, where the optimal parameter bit allocation per CED size is determined by means of a Monte Carlo simulation. Subsequently, the optimal reduced set is integrated in the existing Galileo I/NAV message, since it is not only size but also the location and repetition rate of the reduced CED in the navigation message that determine the final decrease in TTFFD. A simulation is developed where the three reduction strategies are combined and applied to one year of Galileo navigation messages and almanacs starting from October 2017. The current I/NAV message has a size of 428 bits and an average TTFFD of 25.4 seconds. The relative expression of the CED parameters, the absorption of the clock time reference and ephemeris time reference yield a 76, 15 and 10 bit reduction respectively, without a significant decrease in position accuracy expressed as the signal-in-space ranging error (SISRE). The reduction in size that can be realized by truncation results from a trade-off with the maximum acceptable level of SISRE. When combining all three reduction strategies a 296 bit, i.e. 69%, size reduction can be realized at a SISRE level of 10.04 meters, yielding a 132 bit CED. 66% of the size reduction is in this case achieved by parameter truncation. To maintain backward compatibility, the spare and reserved bits of the I/NAV message are used to integrate the reduced set. This finally results in an average TTFFD of 6 seconds, which is a decrease of almost 20 seconds. With the reduced CED the user gains full independence of out-of-band channels for the computation of a fast position fix. In addition, it decreases the impact of bit errors on the TTFF and increases the chance of receiving an error free set of first fix data. Moreover, the reduced CED is not only of interest to fast fix applications that desire a decrease in waiting time. Positioning based on the reduced set also decreases the time the receiver has to be "on" to read the navigation data and consequently the receiver's power usage. This leads to a second type of applications that benefits from the reduced CED: low-power applications that do not require a high accuracy, such as freight management, wildlife tracking and stolen goods trackers. To conclude, the constructed reduced CED provides multiple advantages for a wide range of GNSS users and should therefore be considered as a purpose for the spare and reserved bits of the Galileo I/NAV message.Aerospace Engineerin
Interaksjon med brukere i Nav: Analyse av samtaledata som grunnlag for fagutvikling
No full textMøter mellom Nav-veileder og bruker er viktige både for samfunnets mål om flest mulig i arbeid, og for den enkelte bruker som har behov for veiledning, økonomisk eller praktisk hjelp. Gjennom FOU-satsingen «Interaksjon med brukere» legger Nav vekt på brukermøtene og hvordan kvaliteten i disse henger sammen med målene om aktivisering og brukermedvirkning.
Denne metodologiske artikkelen bruker norsk og internasjonal forskning om samtaler i arbeids- og velferdssektoren som empirisk grunnlag for å diskutere hvordan ulike metoder er egna til å belyse ulike problemstillinger. Detaljert analyse av samarbeidet og samspillet i faktiske brukermøter er en lite brukt metode i forskning om Nav. I denne artikkelen diskuterer vi derfor hva som kan oppnås gjennom å gjøre nærstudier av interaksjonen i brukermøter med utgangspunkt i lyd-/bildeopptak og med verktøy fra samtaleforskning. Vi gir eksempler på hvordan analyse av samtaledata kan gi grunnlag for å nyansere standardiserte råd om kommunikasjon og belyse hvordan brukermøtets interaksjonelle forløp skaper vilkår for deltakelse i samtalen.
Å være samtaleleder i brukermøter er en viktig del av Nav-veilederes jobb. Denne artikkelen bidrar med en forskningsbasert begrunnelse for hvorfor bevisstgjøring om samtalens dynamikk i brukermøtene bør være del av fagutviklingen i Nav.publishedVersionThis article is downloaded from www.idunn.no. © 2018 Author(s).

Membrane trauma and Na+ leak from Nav1.6 channels
No full textDuring brain trauma, white matter experiences shear and stretch forces that, without severing axons, nevertheless trigger their secondary degeneration. In central nervous system (CNS) trauma models, voltage-gated sodium channel (Nav) blockers are neuroprotective. This, plus the rapid tetrodotoxin-sensitive Ca2+ overload of stretch-traumatized axons, points to "leaky" Nav channels as a pivotal early lesion in brain trauma. Direct effects of mechanical trauma on neuronal Nav channels have not, however, been tested. Here, we monitor immediate responses of recombinant neuronal Nav channels to stretch, using patch-clamp and Na+-dye approaches. Trauma constituted either bleb-inducing aspiration of cell-attached oocyte patches or abrupt uniaxial stretch of cells on an extensible substrate. Nav1.6 channel transient current displayed irreversible hyperpolarizing shifts of steady-state inactivation [availability(V)] and of activation [g(V)] and, thus, of window current. Left shift increased progressively with trauma intensity. For moderately intense patch trauma, a approximately 20-mV hyperpolarizing shift was registered. Nav1.6 voltage sensors evidently see lower energy barriers posttrauma, probably because of the different bilayer mechanics of blebbed versus intact membrane. Na+ dye-loaded human embryonic kidney (HEK) cells stably transfected with alphaNav1.6 were subjected to traumatic brain injury-like stretch. Cytoplasmic Na+ levels abruptly increased and the trauma-induced influx had a significant tetrodotoxin-sensitive component. Nav1.6 channel responses to cell and membrane trauma are therefore consistent with the hypothesis that mechanically induced Nav channel leak is a primary lesion in traumatic brain injury. Nav1.6 is the CNS node of Ranvier Nav isoform. When, during head trauma, nodes experienced bleb-inducing membrane damage of varying intensities, nodal Nav1.6 channels should immediately "leak" over a broadly left-smeared window current range.Peer reviewedfinal article publishedblebsodium dyestretchshea
