description: While Research Information continues to mature as an area of expertise, discussions regarding the implementation and adoption of standardisation initiatives, such as CASRAI and CERIF, have intensified. Possessing the capacity to use a standard does not obligate its adoption, so the extent to which standards are employed varies across use cases and institutions, in a way that is difficult to qualify and determine. We are presenting a light-weight visualisation framework for presenting, comparing and improving the adoption of research information standards for research institutions. The framework is implemented for providing insight into identifier adoption at the University of Cambridge. The tool is easy to deploy and implement, and the insights it generates are intended to express clearly the extent to which Research Information standards have been adopted. Furthermore, the framework can be used to make this adoption knowledge available as linked open data held at a local level, reducing the need for costly metastudies and helping the standardisation community to monitor and focus standardisation development.

description: The Sunyaev-Zel'dovich (SZ) effect is a powerful tool for studying clusters of galaxies and cosmology. Large mm-wave telescopes are now routinely detecting and mapping the SZ effect in a number of clusters, measure their comptonisation parameter and use them as probes of the large-scale structure and evolution of the universe. We show that estimates of the physical parameters of clusters (optical depth, plasma temperature, peculiar velocity, non-thermal components etc.) obtained from ground-based multi-band SZ photometry can be significantly biased, owing to the reduced frequency coverage, to the degeneracy between the parameters and to the presence of a number of independent components larger than the number of frequencies measured. We demonstrate that low-resolution spectroscopic measurements of the SZ effect that also cover frequencies $> 270$ GHz are effective in removing the degeneracy. We used accurate simulations of observations with lines-of-sight through clusters of galaxies with different experimental configurations (4-band photometers, 6-band photometer, multi-range differential spectrometer, full coverage spectrometers) and different intracluster plasma stratifications. We find that measurements carried out with ground-based few-band photometers are biased towards high electron temperatures and low optical depths, and require coverage of high frequency and/or independent complementary observations to produce unbiased information; a differential spectrometer that covers 4 bands with a resolution of $\sim 6 \ GHz$ eliminates most if not all bias; full-range differential spectrometers are the ultimate resource that allows a full recovery of all parameters.

description: Bluetooth is a promising wireless technology that enables portable devices to form short-range wireless ad hoc networks. Unlike wireless LAN, the communication of Bluetooth devices follow a strict master slave relationship, that is, it is not possible for a slave device to directly communicate with another slave device even though they are within the radio coverage of each other. For inter piconet communication, a scatternet has to be formed, in which some Bluetooth devices have to act as bridge nodes between piconets. The Scatternet formed have following properties in which they are connected i.e every Bluetooth device can be reached from every other device, Piconet size is limited to eight nodes [1]. The author of this research paper have studied different type of routing protocol and have made efforts to improve throughput and reduce packet loss due to failure in the routing loop and increased mobility and improve the cohesive network structure, resolve the change topology conflicts [2], and a successful & efficient transfer of packet from source to destination.

description: Ship wave ray tracing including surface tension The aim of this work is to darify the validity of ship wave ray theories at and near the ship's surface. As previous numerical investigations have led to ambiguities due to a breakdown of the ray analysis near the bow and stern stagnation points, we shall take care for the surface tension effect in order to milden such deficiencies; then the wave length never surpasses a positive minimum length which is attained at the boundary of a finite waveless zone around a stagnation point. It is found, however, that the ray equations degenerate at these boundaries, and that rays can be traced into the far field only if their starting point is selected outside a finite belt surrounding the waveless zone. For a class of bi-circular prismatic struts of infinite downward extent, we investigated two alternative formulations of the free surface condition and their implications for the ray geometry. For low speeds we found in both cases an increase of the Kelvin wave cusp angle due to capillarity. We extended the ray tracing to capillary waves ahead of a blunt bow.

description: This report introduces three protocols for communication in infrastructure networks consisting of a central server, stationary basestations and mobile devices. Mobile devices use IEEE 802.15.4 to communicate with the basestations. Among other things, the proposed protocols differ in their location management and in the routing of downlink and uplink packets. Through extensive simulations the protocols are compared with the focus on latency and packet loss metrics. The strength of each protocol depends on the traffic pattern caused by an application. The report concludes with a recommendation for the usage of each protocol.

description: This paper reports on the deposition and photoluminescence of amorphous and crystalline thin films of zinc gallium oxide with Ga:Zn atomic ratio varied between 0.3 and 5.7. The films are prepared by reactive direct current magnetron co-sputtering from liquid/solid gallium/zinc targets onto fused quartz substrates; the temperature of the substrate is varied from room temperature (RT) to 800°C. The sputtering process is effectively controlled by fixing the sputtering power of one of the targets and controlling the power of the other target by plasma optical emission spectroscopy. The method, in conjunction with oxygen flow adjustment, enables the production of near-stoichiometric films at any temperature used. The composition analysis suggests a few at.% oxygen deficiency in the films. The resulting deposition rate is at least an order of magnitude higher compared to the commonly used radio-frequency sputtering from a ceramic ZnO:Ga2O3 target. Deposited onto unheated substrates, the films with Ga:Zn {\approx} 2 are X-ray amorphous. Well-defined X-ray diffraction peaks of spinel ZnGa2O4 start to appear at a substrate temperature of 300°C. The surface of the as-deposited films is dense and exhibits a fine-featured structure observed in electron microscopy images. Increasing the deposition temperature from RT to 800°C eliminates defects and improves crystallinity, which for the films with Ga:Zn ratio close to 2 results in an increase in the optical band gap from 4.6 eV to 5.1 eV. Room temperature photoluminescence established the main peak at 3.1 eV (400 nm); a similar peak in Ga2O3 is ascribed to oxygen-vacancy related transitions. A prominent feature around 2.9 eV (428 nm) is attributed to self-activation center of the octahedral Ga-O groups in the spinel lattice of ZnGa2O4. It was found that photoluminescence from ZnGa2O4 depends significantly on the ratio Ga:Zn.

description: Globally, large amounts of various crops such as cereals, oilseeds, nuts and spices are contaminated with mycotoxins during pre-harvest, postharvest handling, processing and/or storage. Mycotoxin contamination results into economic and health issues, and valorisation options of contaminated crops are urgently needed. The aim of this research was to evaluate whether quality feed and fertilizer can be safely produced from naturally mycotoxin contaminated crops using black soldier fly larvae (BSFL, Hermetia illucens L.) under realistic field conditions in East Africa. Naturally mycotoxin contaminated maize (corn; Zea mays L.) was used as a model due its prevalence as food and feed and utilized by BSFL together with local agri-food by-products at a research facility in Rwanda. To assess the influence of the initial maize mycotoxin contamination and maize inclusion, larval diets with three mycotoxin contamination level and two maize inclusion levels were tested. BSFL were tolerant against the high mycotoxin concentrations (e.g. 99.4 μg aflatoxin B1 kg dry mass-1) as the presence of mycotoxins in the substrate did not affect BSFL mass. Product safety was assessed by quantifying the presence of 38 common and emerging mycotoxins and metabolites in the maize, substrates and BSFL products (e.g. larvae and frass). The results show that it is possible to produce feed and fertilizer with BSFL considered safe within EU and East African legal limits from maize contaminated with mycotoxin contaminated maize typical for East Africa. Thereby, this research works towards the safe recycling of nutrients from mycotoxin contaminated maize within the food system in East Africa and beyond.

description: We report a systematic investigation of orthorhombic perovskite-type RCrO3 powder samples by Raman scattering for nine different rare earth R3+ cations (R = Y, La, Pr, Sm, Gd, Dy, Ho, Yb, Lu). The room-temperature Raman spectra and the associated phonon mode assignment provide reference data for structural investigation of the whole series of RCrO3 orthochromites and phonon ab-initio calculations. The assignment of the chromite spectra and comparison with Raman data on other orthorhombic perovskites allows correlating the phonon modes with the structural distortions in the RCrO3 series. In particular, two Ag modes are identified as octahedra rotation soft modes as their positions scale linearly with the octahedra tilt angle of the CrO6 octahedra.

description: Nonlinear waves in a liquid containing gas bubbles are considered in the three-dimensional case. Nonlinear evolution equation is given for description of long nonlinear pressure waves. It is shown that in the general case the equation is not integrable. Some exact solutions for the nonlinear evolution equation are presented. Application of the Hirota method is illustrated for finding multi-soliton solutions for the nonintegrable evolution equation in the three-dimensional case. The stability of the one-dimensional solitary waves is investigated. It is shown that the one-dimensional solitary waves are stable to transverse perturbations.

description: Diacritical marks play a crucial role in meeting the criteria of usability of typographic text, such as: homogeneity, clarity and legibility. To change the diacritic of a letter in a word could completely change its semantic. The situation is very complicated with multilingual text. Indeed, the problem of design becomes more difficult by the presence of diacritics that come from various scripts; they are used for different purposes, and are controlled by various typographic rules. It is quite challenging to adapt rules from one script to another. This paper aims to study the placement and sizing of diacritical marks in Arabic script, with a comparison with the Latin's case. The Arabic script is cursive and runs from right-to-left; its criteria and rules are quite distinct from those of the Latin script. In the beginning, we compare the difficulty of processing diacritics in both scripts. After, we will study the limits of Latin resolution strategies when applied to Arabic. At the end, we propose an approach to resolve the problem for positioning and resizing diacritics. This strategy includes creating an Arabic font, designed in OpenType format, along with suitable justification in TEX.

description: The aim of this study was to further characterize three prominent proteins of the rat sperm tail, ODF14, FS14 and Spag5. FS14 and ODF14 were used to generate antibodies which were subsequently affinity-purified and used to screen a rat testicular cDNA library. Two cDNAs were isolated (designated 1017 and 1038) and it was determined that 1017 was homologous to mouse ornithine decarboxylase antizyme 3. However, it was found that 1038 resulted from a chimeric mRNA, consisting of sequences from two different chromosomes. Spag5 was originally thought to be testis-specific and was identified due to its interaction with Odf1 using the yeast two hybrid system. Knock-out studies revealed no significant phenotype in mice and spag5 was found to be 73% similar to the human mitotic spindle protein, Astrin. We found that in spermatogenesis Spag5 does not appear to localize to either the axoneme or the meiotic spindle, but instead associates with ODF. In mitotic cells it colocalizes with Astrin in the mitotic spindle and the cytoplasm of rat IEC-18 cells.

description: Let $f(x,y)=0$ and $l(x,y)=0$ be respectively a singular and a regular analytic curve defined in the neighborhood of the origin of the complex plane. We study the family of analytic curves $f(x,y)-tl(x,y)^M=0$, where $t$ is a complex parameter. For all but a finite number of parameters the curves of this family have the same embedded topological type. The exceptional parameters are called special values. We show that the number of nonzero special values does not exceed the number of components of the curve $f(x,y)=0$ counted without multiplicities. Then we apply this result to estimate the number of critical values at infinity of complex polynomials in two variables.

title: Modelling and characterisation of porous materials
Creators: name: Alsayednoor, Jafar
Publisher: name: University of Glasgow
Year: 2013

description: Porous materials possessing random microstructures exist in both organic (e.g. polymer foam, bone) and in-organic (e.g. silica aerogels) forms. Foams and aerogels are two such materials with numerous engineering and scientific applications such as light-weight cores in sandwich structures, packaging, impact and crash structures, filters, catalysts and thermal and electrical insulators. As such, design and manufacture using these materials is an important task that can benefit significantly from the use of computer aided engineering tools. With the increase in computational power, multi-scale modelling is fast becoming a powerful and increasingly relevant computational technique. Ultimately, the aim is to employ this technique to decrease the time and cost of experimental mechanical characterisation and also to optimise material microstructures. Both these goals can be achieved through the use of multi-scale modelling to predict the macro-mechanical behaviour of porous materials from their microstructural morphologies, and the constituent materials from which they are made. The aim of this work is to create novel software capable of generating realistic randomly micro-structured material models, for convenient import into commercial finite element software. An important aspect is computational efficiency and all techniques are developed paying close attention to the computation time required by the final finite element simulations. Existing methods are reviewed and where required, new techniques are devised. The research extensively employs the concept of the Representative Volume Element (RVE), and a Periodic Boundary Condition (PBC) is used in conjunction with the RVEs to obtain a volume-averaged mechanical response of the bulk material from the micro-scale. Numerical methods such as Voronoi, Voronoi Laguerre and Diffusion Limited Cluster-Cluster Aggregation are all employed in generating the microstructures, and where necessary, enhanced in order to create a wide variety of realistic microstructural morphologies, including mono-disperse, polydisperse and isotropic microstructures (relevant to gas-expanded foam materials) as well as diffusion-based microstructures (relevant for aerogels). Methods of performing large strain simulations of foams microstructures, up to and beyond the onset strain of densification are developed and the dependence of mechanical response on the size of an RVE is considered. Both mechanical and morphological analysis of the RVEs is performed in order to investigate the relationship between mechanical response and internal microstructural morphology of the RVE. The majority of the investigation is limited to 2-d models though the work culminates in extending the methods to consider 3-d microstructures.

description: It is shown that the Hyperbolic Branch of the radiative electroweak symmetry breaking contains in it three regions: the Focal Point, Focal Curves, and Focal Surfaces. Further, the Focal Point is shown to lie on the boundary of a Focal Curve. These focal regions allow for a small $μ$ while scalar masses can become large and may lie in the several TeV region. It is shown that for the mSUGRA model the current LHC-7 constraint depletes the Focal Point region while regions on Focal Curves and Focal Surfaces remain largely intact. The LHC implications for models which lie on Focal Curves are briefly discussed as well as the implications of dark matter constraints for the Focal Point, Focal Curves and Focal Surfaces are discussed.

Biological insights of transcription factor through analyzing ChIP-Seq data

Publisher: name: University of British Columbia

description: ChIP-Seq is a technology for detecting in vivo transcription factor binding sites or histone modification sites on a genome wide scale. How to utilize the large scale data and find out biological insights is a challenging question for us. Here, we analyzed three ChIP-Seq data sets for human HeLa cell, includ ing data of a transcription factor called STAT1, data of RNA polymerase II (Po12), and data of histone monomethylation (Mel). With these data sets, we looked into the spacial relationship between STAT1 binding sites, Po12 binding sites, Mel flanked regions and the gene transcription start sites; we checked the intersection of locations of STAT1 binding sites, Po12 bind ing sites and Mel flanked regions; we did de novo motif discovery for the sequences around the STAT1 binding sites, and predicted several transcription factors whose binding sites may form cis-regulatory module with STAT1 binding site; we put the STAT1-centered sequences into different categories based on their spacial relationship with Po12 binding sites and Mel flanked regions, and found that the de novo discovered motifs’ occurrence rates are different in sequences of different categories; we also analyzed the ChIP-Seq data along with gene expression data, and found that STAT1 binding may be related with genes’ differential expression under IFN-gamma stimulation. We suggest that further ChIP-Seq experiment be carried out for TFs corresponding to the de novo predicted motifs, and that gene expression be characterized for the IFN-gamma stimulated HeLa cell on the whole genome scale.

description: The one-loop quark contribution to the QCD effective potential for the homogeneous Abelian gluon field in the presence of external strong electromagnetic field is evaluated. The structure of extrema of the potential as a function of the angles between chromoelectric, chromomagnetic and electromagnetic fields is analyzed. In this setup, the electromagnetic field is considered as an external one while the gluon field represents domain structured nonperturbative gluon configurations related to the QCD vacuum in the confinement phase. Two particularly interesting gluon configurations, (anti-)self-dual and crossed orthogonal chromomagnetic and chromoelectric fields, are discussed specifically. Within this simplified framework it is shown that the strong electromagnetic fields can play a catalysing role for a deconfinement transition. At the qualitative level, the present consideration can be seen as a highly simplified study of an impact of the electromagnetic fields generated in relativistic heavy ion collisions on the strongly interacting hadronic matter.

In contrast to the S=1/2 case, where the only type of local excited state is a doubly occupied state of energy $U$, several local excited states with occupation up to 4 electrons are present. As a consequence, we show that two distinct resonating scattering regimes can be accessed depending on the incident photon energy. For $\hbarω_{in}\lesssim U$, the standard Loudon-Fleury operator remains the leading term of the expansion as in the spin-1/2 case. For $\hbarω_{in}\lesssim4U$, a second resonant regime is found with a leading term that takes the form of a biquadratic coupling $\sim({\bf S}_{i}\cdot{\bf S}_{j)^{2}$. Consequences for the Raman spectra of S=1 magnets with magnetic or quadrupolar order are discussed. Raman scattering appears to be a powerful probe of quadrupolar order.

description: In the framework of Monitoring by Ocean Drifters (MONDO) Project, a set of Lagrangian drifters were released in proximity of the Brazil Current, the western branch of the Subtropical Gyre in the South Atlantic Ocean. The experimental strategy of deploying part of the buoys in clusters offers the opportunity to examine relative dispersion on a wide range of scales. Adopting a dynamical systems approach, we focus our attention on scale-dependent indicators, like the finite-scale Lyapunov exponent (FSLE) and the finite-scale (mean square) relative velocity (FSRV) between two drifters as function of their separation, and compare them with classic time-dependent statistical quantities like the mean square relative displacement between two drifters and the effective diffusivity as functions of the time lag from the release. We find that, dependently on the given observable, the quasigeostrophic turbulence scenario is overall compatible with our data analysis, with discrepancies from the expected behavior of 2D turbulent trajectories likely to be ascribed to the non stationary and non homogeneous characteristics of the flow, as well as to possible ageostrophic effects. Submesoscale features of O(1) km are considered to play a role, to some extent, in determining the properties of relative dispersion as well as the shape of the energy spectrum. We present, also, numerical simulations of an OGCM of the South Atlantic, and discuss the comparison between experimental and model data about mesoscale dispersion.

Cooperative Detection Of Pue Attacks In Crns

description: Cognitive radio networks (CRNs) act as secondary users of the spectrum

left unused by licensed services or primary users thus improving spectrum usage.

However, the specific features of CRNs give rise to new security threats, such as

the primary user emulation (PUE) attack, in which a malicious user impersonates

a primary transmission to prevent the CRN from using a vacant band. With the

aim of detecting such kind of attacks, in this chapter we describe a cooperative

localization method specifically suited to CRNs. Localization is a powerful PUEdetection technique in several scenarios where the position of the primary users is well known, e.g. TV towers in IEEE 802.22 standard. Simulations results show the goodness of the proposed method and its suitability to typical CRN scenarios.

description: In this paper we examine the structure of complex points of real 4-manifolds embedded into complex 3-manifolds up to isotopy. We show that there are only two types of complex points up to isotopy and as a consequence, show that any such embedding can be deformed by isotopy to a manifold having 2-complete neighborhood basis.

description: Tungsten Inert Gas welding (TIG) process is an important module in many industrial operations. The TIG welding parameters are the most important factors affecting the quality, productivity and cost of welding. In this process proper selection of input welding parameters is necessary in order to obtain a good quality weld and subsequently increase the productivity of the process. A design of experiments based on Taguchi technique has been used to acquire the data. An L9 Orthogonal array employed to investigate the welding characteristics of similar joint and optimize the welding parameters.In present research work response graphsare considered for the study of influence of welding parameters like welding current, Gas Flow Rate and Filler Rod on strength of Mild steel thin sheet during welding. TheTensile test show that welding current and filler rod has increased the strength while effect of Gas Flow rate alone has almost no effect on welding strength but its interaction with other parameters makes it quite significant in increasing the weld strength
Filtering and parameter estimation for electricity markets

Publisher: name: University of British Columbia

description: The growing complexity of energy markets requires the introduction of in creasingly sophisticated tools for the analysis of market structures and for the modeling of the dynamics of spot market and forward prices. In order for market participants to use these markets in an efficient way, it is important to employ good mathematical models of these markets. This has proved to be particularly difficult for electricity, where markets are complex, and ex hibit a number of unique features, mainly due to the problems involved in storing electricity. In this thesis we propose three models for electricity prices. All are multifactor models, that is, as well as an observable spot price they assume the existence of an unobservable long term mean’ process. The introduction of such additional processes helps to explain the relation between spot and futures prices. In the first part of the thesis we introduce a two factor Gaus sian model for prices. Using the Kalman filter, and based on both spot and forward prices, we successfully estimate parameters for simulated data. We then estimate parameters for the German EEX market, and compare our fitted model with the observed prices. We find that this model does capture some features of the EEX market, but it fails to exhibit the price spikes which are a prominent feature of true spot prices. We therefore introduce a second model, which includes jumps. The inclusion of jumps has the potential to give a better explanation of the behavior of electricity prices, but it creates difficulties in the estimation of parameters. This is because as the model noise is non-Gaussian the Kalman filter cannot be applied satisfactorily. We implement the particle filter adopting the Liu & West approach for the jump model. This method allows us to identify the hidden process in the model, and to estimate a small number of parameters. The third model is a new model for electricity prices based on the inverse Box-Cox transformation. This model is non-linear with Gaussian noise, and can generate price spikes using fewer parameters than a multi-factor jump-diffusion model. In this context, we successfully applied the Unscented Kalman filter to estimate the parameters.

description: Helsinki University Library supports open science in all stages of research. Many of the services are already established and in use, some are under development and some on an idea stage.

We work in teams: teams for research data, metrics and open access have a central role in open science, although at least equally important is the contribution of information literacy teaching, customer services and information technology.

In our poster, we present the services connected to the research process: from planning the research to reuse of the data and visibility services of the publications.

The services covered are e.g. guidance in research data management, support for self-archiving and open access publishing (Helda - open repository, Terkko/Viikki ePrints, Tuhat-research information system), educating open science for doctoral students (“Managing Scientific Information” course for Doctoral School in Health Sciences), visibility services (such as Scholar Chart, Top Cited @UH, PlumX), marketing, promoting and raising awareness (events & pop up information stands), purchasing memberships (such as BMC, PeerJ & Springer Open) and networking nationally as well as internationally.

description: An epidemic model with distributed time delay is derived to describe the dynamics of infectious diseases with varying immunity. It is shown that solutions are always positive, and the model has at most two steady states: disease-free and endemic. It is proved that the disease-free equilibrium is locally and globally asymptotically stable. When an endemic equilibrium exists, it is possible to analytically prove its local and global stability using Lyapunov functionals. Bifurcation analysis is performed using DDE-BIFTOOL and traceDDE to investigate different dynamical regimes in the model using numerical continuation for different values of system parameters and different integral kernels.

description: We study the QCD phase structure at high temperature and density adopting a histogram method. Because the quark determinant is complex at finite density, the Monte-Carlo method cannot be applied directly. We use a reweighting method and try to solve the problems which arise in the reweighting method, i.e. the sign problem and the overlap problem. We discuss the chemical potential dependence of the probability distribution function in the heavy quark mass region and examine the applicability of the approach in the light quark region.
