description: The 'Institut für OstseeforschungWarnemünde (IOW)', the 'Biologische Anstalt Helgoland (BAH)', and the 'Bundesamt für Seeschiffahrt und Hydrographie (BSH)', carried out five field campaigns with the research vessels "A.v.HUMBOLDT" and "HEINCKE". These activities were a part of the German contribution to the World Ocean Circulation Experiment (WOCE) in 1991-1992. The main aim was directed on the investigation of poleward going undercurrents within the system of eastern boundary currents (EBC). The area under investigatien was placed within the WOCE control volumes AR6 and AR16 off Portugal and Morocco. Among other things, the mass field was profiled using a CTD-probe down to about 2000 m depth (200 Bar) along a couple of hydrographic transects. This report compiles all vertical plots against the pressure resulting from in-situ values in temperature, salinity, and dissolved oxygen together with those of the potential density-relative to the sea surface.

Dabei wurde u.a. das Massenfeld routinemäßig bis zu einer Wassertiefe von etwa 2000 m (200 Bar) durch eine Vielzahl von CTD-Sondierungen entlang hydrographischer Schnitte in den WOCE-Gebieten AR6 und AR16 vermessen. Für jeden dieser Schnitte sind die in-situ Werte der Temperatur, Salz- und Sauerstoffgehalt sowie die Rechengröße der potentiellen Dichte relativ zur Meeresoberfläche als Vertikalschnitte über den Druck dargestellt worden.

description: Origin of the non-magnetic phase transition in PrTi$_2$Al$_{20}$, reported earlier in the macroscopic study, has been asserted microscopically using elastic and inelastic neutron scattering techniques. It has been shown spectroscopically that the crystalline-electric-field ground state is a non-magnetic $Γ_3$ doublet, whereas the excited states are two triplets ($Γ_4$ and $Γ_5$) and a singlet ($Γ_1$). The diffraction experiment under external magnetic field shows that the non-magnetic transition is indeed ferro-quadrupolar ordering, which takes place as a consequence of cooperative removal of the ground-state-doublet degeneracy. It is therefore concluded that PrTi$_2$Al$_{20}$ is another rare example of Pr compounds exhibiting non-magnetic quadrupolar order.

Flying on the wings of trust : the story of the Delta farmland and wildlife trust an example of collaborative community based resource management
Creators: name: Anderson, Elaine Susan
Publisher: name: University of British Columbia
Year: 2010

description: Competition over resources is threatening both agricultural viability and wildlife habitat around the world. One of the ways this problem can be addressed is through agri-environmental non-government organizations (NGOs) that practice community based collaborative resource management. However, there is a lack of academic research on both the formation and development of agri-environmental NGOs in First World industrialized nations and the role that policy plays in their formation and development. It is important to understand how policy affects the formation and development of such organizations in order to address any policy gaps that may exist. My research examines how a community in conflict acknowledged the potential loss of both agricultural and wildlife resources and came together to identify ways to share resources more equitably. Since 1993, the Delta Farmland and Wildlife Trust (DFWT) has been working with farmers and environmentalists to balance the needs of wildlife with the needs of farmers. The DFWT shares the cost of specific management practices that benefit agriculture and wildlife. My research involved face-to-face interviews with 28 individuals who had been involved in the formation and/or development of the DFWT. Content analysis was used to identify common themes in the interviews. Secondary sources of information were reviewed to triangulate the results. The formation of the DFWT came about due to a number of conflicts occurring in Delta at the time. The conflicts were having a negative impact on both agricultural and wildlife habitat viability. The key driving force in the formation of the DFWT appeared to be the willingness of agricultural and conservation interests to work together. Government policy appears to have enabled the formation of the DFWT. However, policy may be impeding the development of the DFWT by limiting the ability of the DFWT to provide agri-environmental stewardship programs in an optimal manner. Agri-environmental policies from three countries were reviewed and a variety of policies that could be used to encourage agri-environmental stewardship in Canada were identified. This research will be of value to individuals and organizations interested in collaborative community based resource management as well as to those interested in developing supportive agri-environmental policy.

description: In the 21st century, cancer is seen as the biggest
 obstacle to the prolongation of life expectancy and the most
 important cause of death in every country in the world.
 According to the GLOBOCAN 2018 report produced by the
 International Agency for Research on Cancer (IARC), it is
 predicted that 18.1 million new cancer cases will be diagnosed
 based on all age groups and genders for 2018 and approximately
 9.6 million people will die due to cancer. Considering all these
 situations, as well as the studies to increase the effectiveness of
 classical methods for cancer treatment, the search for
 alternative treatment methods have been accelerated. High
 Intensity Focused Ultrasound (HIFU) is a promising method for
 cancer researchers in recent years. Dosimetric studies are
 required for the widespread use of HIFU in the clinic.
 In this study, temperature characterization results, which
 are the basis of our research for the application of HIFU with
 dosimetric approach to colon cancer cell lines, are given.

description: Radio-frequency reflectometry in silicon single-electron transistors (SETs) is presented. At low temperatures (<4 K), in addition to the expected Coulomb blockade features associated with charging of the SET dot, quasi-periodic oscillations are observed that persist in the fully depleted regime where the SET dot is completely empty. A model, confirmed by simulations, indicates that these oscillations originate from charging of an unintended floating gate located in the heavily doped polycrystalline silicon gate stack. The technique used in this experiment can be applied for detailed spectroscopy of various charge defects in nanoscale SETs and field effect transistors

description: We experimentally observe the effect of photo-generated carriers on the spectral diffusion of a quantum dot (QD) coupled to a photonic crystal (PC) cavity. In this system, spectral diffusion arises in part from charge fluctuations on the etched surfaces of the PC. We find that these fluctuations may be suppressed by photo-generated carriers, leading to a reduction of the measured QD linewidth by a factor of ~2 compared to the case where the photo-generated carriers are not present. This result demonstrates a possible means of countering the effects of spectral diffusion in QD-PC cavity systems and thus may be useful for quantum information applications where narrow QD linewidths are desired.

description: Intense and collimated neutrino beams are produced by charm and beauty particle decays from proton-proton collisions at the LHC. A neutrino experiment would be run parasitically without interrupting the LHC physics program during the collider run. We estimate the neutrino fluxes from proton-proton collisions at $\sqrt{s}=14$ TeV of the LHC with the designed luminosity, $10^{34} \lumi$. By mounting about 200 tons of fiducial volume of a neutrino detector at 300 $\m$ away from the interaction point, about 150,000 of charged current neutrino events per year can be observable.

description: We derive an action-flux formula to compute the volumes of lobes quantifying transport between past- and future-invariant Lagrangian coherent structures of n-dimensional, transitory, globally Liouville flows. A transitory system is one that is nonautonomous only on a compact time interval. This method requires relatively little Lagrangian information about the codimension-one surfaces bounding the lobes, relying only on the generalized actions of loops on the lobe boundaries. These are easily computed since the vector fields are autonomous before and after the time-dependent transition. Two examples in three-dimensions are studied: a transitory ABC flow and a model of a microdroplet moving through a microfluidic channel mixer. In both cases the action-flux computations of transport are compared to those obtained using Monte Carlo methods.

Subjects: Open Science – Open Access – Commodification of academic research – Policy – Copyright law

description: The aim of this short essay is to answer the following question: is Open Science (OS) able to oppose the expansion of commodification of scientific and academic research? The answer is positive only if we conceive OS not only as free access to and reuse of scientific outputs (publications and data), but also as a broader system of values such as democracy, transparency, equity, cooperation, and moral integrity. From this perspective, fostering OS also means investing energy in teaching. We need to educate the new generation of scientists by teaching them the values and practices of OS. In addition, policy and formal norms can help us to build a legal environment apt to embrace the OS principles. In particular, we have to adjust the current research assessment system by decentralising the evaluation process and making it transparent. Moreover, we need to reform copyright law to enable more freedom to access to and reuse of scientific contents. All these efforts may generate a new communication ecosystem in which interaction among ethics, formal norms and technology would guarantee the pluralism of sources and intermediaries.

description: An experiment was performed to determine the effects of chronological age and "extraversion" on reminiscence, using a pursuit rotor task. Three chronological age groups were used: a young adult group (17-25 years ), a middle age group (3 6 - 46 years), and an old group (60-94 years ). From each age group, three subgroups were selected on the basis of scores obtained on the extraversion scale of the Maudsley Personality Inventory (Eys enck, 1959): a high extravert group, a middle extravert group, and a low extravert group. from all three age groups were tested under massed conditions. Young and middle aged Ss were also tested under distributed conditions. Reminiscence was scored by two methods: the method which Eysenck favors, based on the difference between the average of the last three 10-sec. prerest trials and the first 10-sec. postest trial; and the 20-20 method, based on the difference between the last 20 - sec. of prerestand the first 2 0- sec. of postrest practice. Two methods of scoring were used in order to determine whether the results depend specifically up on the method used to compute reminiscence scores. Amount of reminiscence was found to be greatest for the youngest age group regardless of the method of computation used. The age order of size of reminiscence scores obtained by the other two groups varied with the method of computation. No significant differences in amount of reminiscence were found between extraversion subgroups except in the youngest age group. The results are discussed in terms of the Hullian concepts of IR and SIR. It is suggested that as age increases the rate of dissipation of IR decreases and that this affects the development of SIR in different age groups.

description: This report is relevant for actors developing and improving tools and models that can support the second stakeholders’ group. The extraction of relevant architectural traits from LiDAR scan data is useful for use in process-based models that have a simpler 3D implementation of trees (e.g., Hi-sAFe). These architectural traits can be used to design these simplified tree shapes. Furthermore, this extraction can be useful for calculation of tree parameters that can explain variation in tree-crop interactions across sites, which cannot be done, directly from the LiDAR data itself. This report contains a description of the procedure to extract relevant architectural features from a LiDAR scan data set, and presents the LiDAR data set that is available. In this respect we developed a script in the R programming language, and visualized the extracted features.

The Space Environment Of Close-In Exoplanets And Its Implications For Planet Habitability
Creators: name: Cohen, Ofer
Publisher: name: Zenodo
Year: 2016

description: The search for habitable exoplanets is currently focused on planets orbiting M-dwarf stars, due to the close proximity of the habitable zone to the star. However, the traditional habitability definition does not account for the physical space environment near the planets, which can be extreme at close-in orbits, and can lead to erosion of the planetary atmosphere. In order to sustain their atmospheres, M-dwarf planets need to have either an intrinsic magnetic field, or a thick atmosphere. Here we present a set of numerical magnetohydrodynamic simulations of the interaction of an Earth-like magnetized planet and a Venus-like non-magnetized planet with the stellar wind of M-dwarf star. We study space physics aspects of these interactions and their implications for planet habitability.

description: Electrons in a metal are indistinguishable particles that strongly interact with other electrons and their environment. Isolating and detecting a single flying electron after propagation to perform quantum optics like experiments at the single electron level is therefore a challenging task. Up to date, only few experiments have been performed in a high mobility two-dimensional electron gas where the electron propagates almost ballistically. Flying electrons were detected via the current generated by an ensemble of electrons and electron correlations were encrypted in the current noise. Here we demonstrate the experimental realisation of high efficiency single electron source and single electron detector for a quantum medium where a single electron is propagating isolated from the other electrons through a one-dimensional channel. The moving potential is excited by a surface acoustic wave, which carries the single electron along the 1D-channel at a speed of 3\mum/ns. When such a quantum channel is placed between two quantum dots, a single electron can be transported from one quantum dot to the other, which is several micrometres apart, with a quantum efficiency of emission and detection of 96% and 92%, respectively. Furthermore, the transfer of the electron can be triggered on a timescale shorter than the coherence time T2* of GaAs spin qubits6. Our work opens new avenues to study the teleportation of a single electron spin and the distant interaction between spatially separated qubits in a condensed matter system.

From nominal sets binding to functions and lambda-abstraction: connecting the logic of permutation models with the logic of functions

description: Permissive-Nominal Logic (PNL) extends first-order predicate logic with term-formers that can bind names in their arguments. It takes a semantics in (permissive-)nominal sets. In PNL, the forall-quantifier or lambda-binder are just term-formers satisfying axioms, and their denotation is functions on nominal atoms-abstraction. Then we have higher-order logic (HOL) and its models in ordinary (i.e. Zermelo-Fraenkel) sets; the denotation of forall or lambda is functions on full or partial function spaces. This raises the following question: how are these two models of binding connected? What translation is possible between PNL and HOL, and between nominal sets and functions? We exhibit a translation of PNL into HOL, and from models of PNL to certain models of HOL. It is natural, but also partial: we translate a restricted subsystem of full PNL to HOL. The extra part which does not translate is the symmetry properties of nominal sets with respect to permutations. To use a little nominal jargon: we can translate names and binding, but not their nominal equivariance properties. This seems reasonable since HOL---and ordinary sets---are not equivariant. Thus viewed through this translation, PNL and HOL and their models do different things, but they enjoy non-trivial and rich subsystems which are isomorphic.

The following modes are studied: W($μν$)H, W(e$ν$)H, Z($μμ$)H, Z(ee)H and Z($νν$)H, with the Higgs decaying to bb pairs. 95% C.L. upper limits on the VH production cross section are derived for a Higgs mass between 110 and 135 GeV. The expected (observed) upper limit at 115 GeV is found to be 5.7 (8.3) times the standard model expectation.

description: We study theoretically formation of two-dimensional (2D) charge density wave (CDW) in a system of conducting chains at the surface of an insulator due to interaction of quasi 1D surface electrons with phonons. We show that the unscreened long-range Coloumb interaction between the charges induced by fluctuations of the CDW phase stabilizes the finite order parameter value at finite temperatures, and thus the long-range order (LRO) exists. In the case of screened Coloumb interaction the phase fluctuations suppress the phase transition, but decay of the order parameter is rather slow, it obeys a power-law $ \propto r^{-γ}$ with small exponent $γ$

description: With mid-IR and near-IR long-baseline interferometers, we are now mapping the radial distribution of the dusty accreting material in AGNs at sub-pc scales. We currently focus on Type 1 AGNs, where the innermost region is unobscured and its intrinsic structure can be studied directly. As a first systematic study of Type 1s, we obtained mid-/near-IR data for small samples over ~3-4 orders of magnitudes in UV luminosity L of the central engine. Here we effectively trace the structure by observing dust grains that are radiatively heated by the central engine. Consistent with a naive expectation for such dust grains, the dust sublimation radius R_in is in fact empirically known to be scaling with L^1/2 from the near-IR reverberation measurements, and this is also supported by our near-IR interferometry. Utilizing this empirical relationship, we normalize the radial extent by R_in and eliminate the simple L^1/2 scaling for a direct comparison over the samples. We then find that, in the mid-IR, the overall size in units of R_in seems to become more compact in higher luminosity sources. More specifically, the mid-IR brightness distribution is rather well described by a power-law, and this power-law becomes steeper in higher luminosity objects. The near-IR flux does not seem to be a simple inward extrapolation of the mid-IR power-law component toward shorter wavelengths, but it rather comes from a little distinct brightness concentration at the inner rim region of the dust distribution. Its structure is not well constrained yet, but there is tentative evidence that this inner near-IR-emitting structure has a steeper radial distribution in jet-launching objects. All these should be scrutinized with further observations.

description: Die Werkstoffwissenschaften haben in den letzten Jahrzehnten viele verbesserte und neue Materialien entwickelt. Viele Innovationen sind ohne neue Werkstoffe undenkbar. Zu diesen neuen Materialien gehören die Hochleistungskeramiken, die nicht nur thermische und elektrische, sondern auch mechanische Eigenschaften aufweisen, die für spezielle Anwendungen im Maschinenbau besonders geeignet sind. In der Produktentwicklung stößt der Werkstoff Keramik jedoch oft auf Unverständnis, da sowohl die Herstellprozesse als auch die Verbindungstechniken und Berechnungsverfahren von denen der gängigen Werkstoffe abweichen. In dieser Arbeit wird daher die Verwendung von Keramik im Maschinenbau systematisch aufgezeigt. Die Auslegungsgrundlagen der Bruchmechanik werden auf die Anwendungen im Maschinenbau übertragen, mit eigenen Versuchsdaten untermauert und in eine Auslegungsvorschrift überführt. Nach einem historischen Abriss über den Einsatz von Keramik im Maschinenbau werden die derzeitigen Auslegungsmethoden von keramischen Strukturbauteilen zusammengefasst. Es werden empirische Untersuchungen zur mehraxialen Beanspruchbarkeit von Oxidkeramik sowie Siliciumcarbid durchgeführt. Der Festigkeitsnachweis der FKM-Richtlinie des Forschungskuratoriums Maschinenbau wird als Grundlage genommen, um in einer analogen Vorgehensweise die Einflussfaktoren beim Konstruieren mit keramischen Werkstoffen aufzuzeigen. Zwei Anwendungsbeispiele - ein thermisch beanspruchter Stirling-Kolben sowie ein tribologisch beanspruchtes Radiallager - zeigen exemplarisch die konstruktiven Möglichkeiten der Produktentwicklung auf. Dieser Band der Hamburger Schriftenreihe Produktentwicklung und Konstruktionstechnik dient als Grundlage für die Konstruktion um keramische Bauteile in eine - meist metallische - Systemumgebung integrieren zu können.
The Bi-dimensional Impression Management Index (BIMI) : a measure of agentic and communal impression management
Creators: name: Kitching, Sabrina
Publisher: name: University of British Columbia
Year: 2010

description: Although a number of impression management scales are available in the literature, none seem to be concerned with what kind of content is being managed. Previous research suggests that impression management can be separated into two fundamental types of content: agency and communion. Agentic impression management is the tendency to exaggerate one’s courage, leadership or intellectual status. Communal impression management is the tendency to exaggerate one’s claims to be a nice person and good citizen. In Study 1, we developed a new measure of impression management named the Bi-Dimensional Impression Management Index (BIMI): It comprises subscales designed specifically to tap into agentic and communal content. For each content area, we selected the 10 items that shifted the most from honest to fake-good conditions. The resulting subscales were relatively independent (r =.18) and preliminary statistics showed good reliabilities. In Study 2, the BIMI subscales were cross-validated in a new sample, showing good reliabilities and coherent personality correlates. The implications and applicability of the BIMI are discussed, specifically focusing on how this advance is relevant to the literature on faking behaviour.

description: Eine leistungsfähige Vorwärtsfehlerkorrektur ist für jedes moderne Kommunikationssystem essentiell. Um die gesamte Fehlerkorrekturfähigkeit von Kanalcodes wie Low Density Parity Check (LDPC)-Codes nutzen zu können, muss jedoch eine rechnerisch anspruchsvolle Decodierung am Empfänger erfolgen. Insbesondere in Szenarien, in denen die Leistung der Endgeräte oder Latenz der Übertragung begrenzt sind, sind effiziente Decodieralgorithmen von entscheidender Bedeutung. In dieser Arbeit wurde ein neuartiger Dekodierungsansatz entwickelt, der Ideen aus der Informationstheorie und dem maschinellen Lernen kombiniert und zu einem so genannten informationsoptimalen LDPC-Decoder führt. Insbesondere wurde die Information Bottleneck Methode verwendet, um sehr kompakte Darstellungen der in belief-propagation decoding ausgetauschten Nachrichten zu erhalten. Der Dekodierungsansatz wurde zudem verallgemeinert, um diesen auch für praktisch relevante irreguläre LDPC-Codes anwendbar zu machen. Dazu wurde eine weitere Technik entwickelt, das sogenannte „message alingment“. Als Ergebnis konnten LDPC-Dekodierer konstruiert werden, die eine nahezu optimale Leistung (0,2 dB Leistungsverschlechterung) bei sehr geringer Komplexität erreichen. Computersimulationen für irreguläre LDPC-Codes aus dem IEEE 802.11 (WLAN) und DVB-S2 Standard belegen die Anwendbarkeit der entwickelten Decoder auch in standardisierten Kommunikationssystemen.
description: Powerful forward error correction is inevitable for every modern communication system. However, leveraging all error correction capabilities offered by channel codes like low density parity check (LDPC) codes, introduces the burden of computationally demanding decoding at the receiver. Especially in power or latency restricted scenarios, efficient decoding algorithms are of crucial importance. In this thesis a novel decoding approach combining ideas from information theory and machine learning was developed, resulting in a so-called information-optimum LDPC decoder. In particular, the information bottleneck method was used to obtain very compact representations of the exchanged beliefs while performing belief propagation decoding. To generalize the decoding approach, to be applicable also for practically relevant irregular LDPC codes another technique called message alignment was devised. As a result, LDPC decoders can be constructed which pair very low-complexity and near-optimum performance (0.2dB performance degradation). Computer simulations for irregular LDPC codes from the IEEE 802.11 (WLAN) and DVB-S2 standard proof the applicability of the developed decoders also in standardized communication systems.

description: Surveying eighteen 12CO-bright galaxies from the ATLAS3D early-type galaxy sample with the Institut de Radio Astronomie Millimétrique (IRAM) 30m telescope, we detect 13CO(1-0) and 13CO(2-1) in all eighteen galaxies, HCN(1-0) in 12/18 and HCO+(1-0) in 10/18. We find that the line ratios 12CO(1-0)/13CO(1-0) and 12CO(1-0)/HCN(1-0) are clearly correlated with several galaxy properties: total stellar mass, luminosity-weighted mean stellar age, molecular to atomic gas ratio, dust temperature and dust morphology. We suggest that these correlations are primarily governed by the optical depth in the 12CO lines; interacting, accreting and/or starbursting early-type galaxies have more optically thin molecular gas while those with settled dust and gas discs host optically thick molecular gas. The ranges of the integrated line intensity ratios generally overlap with those of spirals, although we note some outliers in the 12CO(1- 0)/13CO(1-0), 12CO(2-1)/13CO(2-1) and HCN/HCO+(1-0) ratios. In particular, three galaxies are found to have very low 12CO(1-0)/13CO(1-0) and 12CO(2-1)/13CO(2-1) ratios. Such low ratios may signal particularly stable molecular gas which creates stars less efficiently than 'normal' (i.e. below Schmidt-Kennicutt prediction), consistent with the low dust temperatures seen in these galaxies.

Benchmarking Fast-to-Alfvén Mode Conversion in a Cold MHD Plasma. II. How to get Alfvén waves through the Solar Transition Region

description: Alfvén waves may be difficult to excite at the photosphere due to low ionization fraction and suffer near-total reflection at the transition region (TR). Yet they are ubiquitous in the corona and heliosphere. To overcome these difficulties, we show that they may instead be generated high in the chromosphere by conversion from reflecting fast magnetohydrodynamic waves, and that Alfvénic transition region reflection is greatly reduced if the fast reflection point is within a few scale heights of the TR. The influence of mode conversion on the phase of the reflected fast wave is also explored. This phase can potentially be misinterpreted as a travel speed perturbation, with implications for the practical seismic probing of active regions.

Evaluating the performance of hypothesis testing in case-control studies with exposure misclassification, using frequentist and Bayesian techniques

description: In epidemiologic studies, measurement error in the exposure variable can have large effects on the power of hypothesis testing for detecting the impact of exposure in the development of a disease. As it distorts the structure of data, more uncertainty is associated with the inferential procedure involving such exposure variables. The underlying theme of this thesis is the adjustment for misclassification in the hypothesis testing procedure. We consider problems involving a correctly measured binary response and a misclassified binary exposure variable in a retrospective case-control scenario. We account for misclassification error via validation data under the assumption of non-differential misclassification. The objective here is to develop a test to check whether the exposure prevalence rates of cases and controls are the same or not, under the frequentist and Bayesian point of view. To evaluate the test developed under the Bayesian approach, we compare that with an equivalent test developed under the frequentist approach. Both these approaches were developed in two different settings: in the presence or absence of validation data, to evaluate whether there is any gain in hypothesis testing for having such validation data. The frequentist approach involves the likelihood ratio test, while the Bayesian test is developed from posterior distribution generated by a mixed MCMC algorithm and a normal prior under realistic assumptions. The comparison between these two approaches is conducted using different simulated scenarios, as well as two real case-control studies having partial validation (internal) data. Different scenarios include settings with varying sensitivity and specificity, sample sizes, exposure prevalence and proportion of unvalidated and validated data. One other scenario that was considered is to evaluate the performance under a fixed budgetary constraint. In the scenarios under consideration, we reach the same conclusion from the two hypothesis testing procedures. The simulation study suggests that the adjusted model (with validation data model) is always better than the unadjusted model (without validation data model). However, exception is possible in the fixed budget scenario.

description: In this paper, we identify and analyze the requirements to design a new routing link metric for wireless multihop networks. Considering these requirements, when a link metric is proposed, then both the design and implementation of the link metric with a routing protocol become easy. Secondly, the underlying network issues can easily be tackled. Thirdly, an appreciable performance of the network is guaranteed. Along with the existing implementation of three link metrics Expected Transmission Count (ETX), Minimum Delay (MD), and Minimum Loss (ML), we implement inverse ETX; invETX with Optimized Link State Routing (OLSR) using NS-2.34. The simulation results show that how the computational burden of a metric degrades the performance of the respective protocol and how a metric has to trade-off between different performance parameters.

description: The informatization practice of countries all over the world has shown that the level of a government's informatization is one main factor that can affect its international competitive power. At present, e-government construction is regarded as one of the most important tasks for the national economy and society upliftment and informatization in Saudi Arabia. Unlike the traditional governments, an e-government takes on a new look with its framework and operation mode more suitable for the contemporary era. In fact, it is a basic national strategy to promote Saudi Arabia's informatization by means of e-government construction. This talk firstly introduces the basic concepts and relevant viewpoints of egovernment, then reviews the development process of e-government in Saudi Arabia, and describes the current states, development strategies of e-government in Saudi Arabia. And also review e-government maturity models and synthesize them e-government maturity models are investigated, in which the authors have proposed the Delloite's six-stage model, Layne and Lee four-stage model and Accenture five-stage model. So, the main e-government maturity stages are: online presence, interaction, transaction, transformation and digital democracy. After that, according to many references, the main technologies which are used in each stage are summarized.

description: We examine the classic problem of homogeneous nucleation and growth by deriving and analyzing a fully discrete stochastic master equation. Upon comparison with results obtained from the corresponding mean-field Becker-Döring equations we find striking differences between the two corresponding equilibrium mean cluster concentrations. These discrepancies depend primarily on the divisibility of the total available mass by the maximum allowed cluster size, and the remainder. When such mass incommensurability arises, a single remainder particle can "emulsify" or "disperse" the system by significantly broadening the mean cluster size distribution. This finite-sized broadening effect is periodic in the total mass of the system and can arise even when the system size is asymptotically large, provided the ratio of the total mass to the maximum cluster size is finite. For such finite ratios we show that homogeneous nucleation in the limit of large, closed systems is not accurately described by classical mean-field mass-action approaches.

description: With the aim of utilizing arrayed waveguide gratings for multi-object spectroscopy in the field of astronomy, we outline several ways in which standard telecommunications grade chips should be modified. In particular, by removing the parabolic-horn taper or multimode interference coupler, and injecting with an optical fiber directly, the resolving power was increased threefold from 2400 \pm 200 (spectral resolution of 0.63 \pm 0.2 nm) to 7000 \pm 700 (0.22 \pm 0.02 nm) while attaining a throughput of 77 \pm 5%. More importantly, the removal of the taper enabled simultaneous off-axis injection from multiple fibers, significantly increasing the number of spectra that can be obtained at once (i.e. the observing efficiency). Here we report that ~ 12 fibers can be injected simultaneously within the free spectral range of our device, with a 20% reduction in resolving power for fibers placed at 0.8 mm off centre.
