description: The majority of scientists, politicians, and organizations agree that climate change is one of the biggest challenges for the 21st century. Reducing the CO2 emissions requires immense efforts in many areas. To combat climate change Carbon Capture and Storage (CCS), where CO2 is captured from the flue gas of power plants and then stored in geological structures must be applied on a massive scale. The poster summarizes the investigations done by the author since primo 2009 related to carbon capture technologies that can be applied in the near future.

description: We show that compactifications of the heterotic string on a circle exhibit at the boundary of moduli space ($R\to 0$, or equivalently the decompactification limit $R \to \infty$) a tower of winding or momentum modes that enhance the $E_8 \times E_8$ or $SO(32)$ gauge symmetry to the affine algebras $(E_9 \oplus E_9)/\sim$ (the identification means that the two copies of $E_9$ share the same central extension) and $\hat{D}_{16}$, respectively. We also prove that these towers of modes satisfy the lattice Weak Gravity and Repulsive Force Conjectures.

description: Observations of synchrotron emission at low radio frequencies reveal a labyrinth of polarised Galactic structures. However, the explanation for the wealth of structures remains uncertain due to the complex interactions between the interstellar medium and the magnetic field. A multi-tracer approach to the analysis of large sky areas is needed. This paper aims to use polarimetric images from the LOFAR Two metre Sky Survey (LoTSS) to produce the biggest mosaic of polarised emission in the northern sky at low radio frequencies (150 MHz) to date. The large area this mosaic covers allows for detailed morphological and statistical studies of polarised structures in the high-latitude outer Galaxy, including the well-known Loop III region. We produced a 3100 square degree Faraday tomographic cube using a rotation measure synthesis tool. We calculated the statistical moments of Faraday spectra and compared them with data sets at higher frequencies (1.4 GHz) and with a map of a rotation measure derived from extragalactic sources. The mosaic is dominated by polarised emission connected to Loop III. Additionally, the mosaic reveals an abundance of other morphological structures, mainly {narrow and extended} depolarisation canals, which are found to be ubiquitous. We find a correlation between the map of an extragalactic rotation measure and the LoTSS first Faraday moment image. The ratio of the two deviates from a simple model of a Burn slab (Burn 1966) along the line of sight, which highlights the high level of complexity in the magnetoionic medium that can be studied at these frequencies.

description: The detection of the 21 cm signal of neutral hydrogen from the Epoch of Reionization (EoR) is challenging due to bright foreground sources, radio frequency interference (RFI), the ionosphere, and instrumental effects. Even after correcting for these effects in the calibration step and applying foreground removal techniques, the remaining residuals in the observed 21 cm power spectra are still above the thermal noise, which is referred to as the "excess variance." We study potential causes of this excess variance based on 13 nights of data obtained with the Low-Frequency Array (LOFAR). We focused on the impact of gain errors, the sky model, and ionospheric effects on the excess variance by correlating the relevant parameters such as the gain variance over time or frequency, local sidereal time (LST), diffractive scale, and phase structure-function slope with the level of excess variance. Our analysis shows that excess variance has an LST dependence, which is related to the power from the sky. And the simulated Stokes I power spectra from bright sources and the excess variance show a similar progression over LST with the minimum power appearing at LST bin 6h to 9h. This LST dependence is also present in sky images of the residual Stokes I of the observations. In very-wide sky images, we demonstrate that the extra power comes exactly from the direction of bright and distant sources Cassiopeia A and Cygnus A with the array beam patterns. These results suggest that the level of excess variance in the 21 cm signal power spectra is related to sky effects and, hence, it depends on LST. In particular, very bright and distant sources such as Cassiopeia A and Cygnus A can dominate the effect. This is in line with earlier studies and offers a path forward toward a solution since the correlation between the sky-related effects and the excess variance is non-negligible.

description: Coupled water and sulfate transport in several types of materials used in historical buildings, among them ceramic brick, sandstone and lime plaster,  is investigated in the conditions of one-sided water and potassium-sulfate-in-water solution uptake. In the experimental work, rod-shaped samples with the dimensions of 20 x 40 x 290 mm are used for the determination of moisture and sulfate concentration profiles. Epoxy resin is employed for water and vapor proof insulation on the lateral sides to assure 1-D water and salt solution transport. In the determination of moisture and sulfate concentration profiles, the specimens are put in contact with distilled water or K2SO4 solution. After chosen time interval, the samples are cut into several pieces. The moisture content is determined in each piece by gravimetric method, the sulfate concentration is measured by ion chromatography.

Experimentally determined K2SO4 concentration profiles and moisture profiles are used for identification of sulfate diffusion coefficient and moisture diffusivity on the basis of inverse analysis using the diffusion-advection model. The moisture diffusivity in dependence on moisture content is calculated in three different ways. First, the moisture diffusivity is calculated from moisture profiles measured for the penetration of distilled water into a specimen. Then, the moisture diffusivity vs. moisture content function is calculated from moisture profiles measured for the penetration of K2SO4 solution. Finally, the third moisture diffusivity vs. moisture function is obtained by the inverse analysis of sulfate concentration profiles under assumption that no sulfate diffusion takes place in the liquid phase, i.e., D=0. It is shown that the possible neglect of sulfate diffusion in the liquid phase and the assumption of D=0 is apparently wrong because the moisture diffusivity calculated from sulfate concentration profiles under this assumption is one to two orders of magnitude higher than moisture diffusivity calculated from moisture profiles.

description: We study 119 B stars located in the Scorpius-Centaurus Association using data from NASA's TESS Mission. We see pulsations in 81 stars (68%) across the full range of effective temperatures. In particular, we confirm previous reports of low-frequency pulsations in stars whose temperatures fall between the instability strips of SPB stars (slowly pulsating B stars) and $δ$ Scuti stars. By taking the stellar densities into account, we conclude that these cannot be p modes and confirm previous suggestions that these are probably rapidly-rotating SPB stars. We also confirm that they follow two period-luminosity relations that are consistent with prograde sectoral g modes that are dipole ($l=m=1$) and quadrupole ($l=m=2$), respectively. One of the stars ($ξ^2$ Cen) is a hybrid pulsator that shows regular spacings in both g and p modes. We confirm that $α$ Cru has low-amplitude p-mode pulsations, making it one of the brightest $β$ Cephei stars in the sky. We also find several interesting binaries, including a very short-period heartbeat star (HD 132094), a previously unknown eclipsing binary ($π$ Lup), and an eclipsing binary with high-amplitude tidally driven pulsations (HR 5846). The results clearly demonstrate the power of TESS for studying variability in stellar associations.

Using Controlled Active Mass (CAM) to decrease energy demand for heating and cooling

Year: 2008

description: Overheating in summer is a problem in buildings with large glass area and low heat capacity constructive materials. Adding some thermal mass to the building is a way to overcome this problem. A new method is using removable thermal mass. This is called Controlled Active Mass (CAM). The CAM is an extra thermal mass which is placed inside the building to decrease energy demand for cooling and heating.
In this work different aspects of refilling a CAM have been studied using numerical analysis. Here the CAM has been selected as a water storage which the water is refreshed every morning. A CAM with water inside has been modeled in a light weight room. The indoor climate of the room and energy demand has been studied when the CAM was refilled with cold water each morning.
The CAM and the room have been modeled and simulated using the Simulink toolbox of Matlab and IBPT (International Building Physics Toolbox). The simulation has been done using weather data for a whole year in Göteborg, Sweden.
The simulation results show that refilling the CAM in a light weight room works well when the temperature is lower than a certain temperature. This temperature depends on the size and properties of the CAM and room. Selecting an optimum format for a CAM inside a room and the time and period of refilling depends on the size, material and location of the CAM and also the time duration.

description: The discovery of novel topological states has served as a major branch in physics and material science. However, to date, most of the established topological states of matter have been employed in Euclidean systems, where the interplay between unique geometrical characteristics of curved spaces and exotic topological phases is less explored, especially on the experimental perspective. Recently, the experimental realization of the hyperbolic lattice, which is the regular tessellation in non-Euclidean spaces with a constant negative curvature, has attracted much attention in the field of simulating exotic phenomena from quantum physics in curved spaces to the general relativity. The question is whether there are novel topological states in such a non-Euclidean system without analogues in Euclidean spaces. Here, we demonstrate both in theory and experiment that novel topological states possessing unique properties compared with their Euclidean counterparts can exist in engineered hyperbolic lattices. Specially, based on the extended Haldane model, the boundary-dominated first-order Chern edge state with a nontrivial real-space Chern number is achieved, and the associated one-way propagation is proven. Furthermore, we show that fractal-like midgap higher-order zero modes appear in deformed hyperbolic lattices, where the number of zero modes increases exponentially with the increase of lattice size. These novel topological states are observed in designed hyperbolic circuit networks by measuring site-resolved impendence responses and dynamics of voltage packets. Our findings suggest a novel platform to study topological phases beyond Euclidean space and may have potential applications in the field of designing high-efficient topological devices, such as topological lasers, with extremely fewer trivial regions.

description: This note outlines several features common to the reception of ancient ruins by the Christian populations of three countries, each located on a different continent. Most of the sites were and are strongly associated with the realm of the dead. Fear of misadventure or calamity typically inspired a respectful avoidance of such pre-Christian sites and structures, but it could also precipitate destructive monkish interventions. Suitably qualified ritual practitioners could access the power of these sites for magical or medical use, which could be either injurious or curative.

Snow and ice on roofs – icicles and climate change

Year: 2008

description: Icicles generation on roofs is a problem in the winter period. People have been killed from falling icicles because they have not been taken away before the size is too large. Building a model to predict, when we have a risk for generation of icicles is very interesting.
The problem with icing and icicles on roof is a complex problem involving architecture, meteorology, glaciology and building physics. The architect decides the layout of the building and the form of roof used. The architectural solution can reduce or increase the risk of icicle generation. The meteorology comes in, as we must know the weather that will permit the icicles formation. The glaciology has the information on the physics behind ice and snow. The building physic is involved as heat air and moisture transfer is involved.
The paper presents an expanded model (first version presented at the Building Physics symposium in Reykjavik 2005) for generation of icicles. We know that climate change will affect the future climate. SMHI has made climate senarios until 2100.
Based on this I will try to give a first estimate on the future risk for icicle falls. A discussion on risks and how to aviod the problem will be given.

Reticulated puffer fish
(Fig. 4).
Tetraodon reticularis
Common names. Reticulated puffer, Reticulated blowfish and Reticulated toadfish.
Habitat. Brackish, Marine, Reef-associated, depth range 1–25 m
Colour. Head and body brown above and whitish below. Dorsal and lateral side of the body, caudal peduncle and caudal fin with white. Abdomen and lower region with longitudinal and parallel brown stripes curving upwards on head, encircling gill anteriorly and forming oblique line on snout region. A back blotch at base of pectoral fin; caudal fin brown and other fins yellow.
Geographical distribution. Widely distributed in the Indo-West Pacific Ocean including the South China Sea and Ryukyu Islands.
Description of species. Dorsal soft spines (total): 10; Pectoral soft spines: 17–19; Anal soft spines: 9–10; Caudal soft spines: 8
Body oblong and nearly cylindrical in cross section with broad head and back. Dorsal profile convex; profile of head straight too slightly concave with blunt snout. Entire body and head, except lips, posterior end of caudal peduncle and fins, covered with prickles. Nasal organ anterior to eye with 2 fleshy lobes formed by bifurcation of a single base. All fins rounded. White lines encircling eye.
Biology and fishery. Epibenthic, occuring in shallow water reefs near sand or seaweed areas. Also found in estuaries and protected muddy bays; juveniles in mangroves and lower reaches of streams. Juveniles feed mainly on planktonic items such as fish eggs, copepods, amphipods, cumaceans and diatoms. Adults occur at moderate depths, often laying on the mud during the day. Feeds on corals, mollusks, crabs and other sand-dwelling invertebrates (Kuthalingam et al., 1973). The size range caught in the trawl varies between 12 and 48cm.
Remarks. This species closely resembles Arothron stellatus though it is easily distinguished by the presence of white spots and longitudinal and parallel brown stripes on lower ventral region while in A. stellatus presence of numerous black spots in the body and more or less oblique black bands in lower ventral region could be seen.
Not edible as flesh of fish is believed to be poisonous therefore this is not a commercial species.

description: In Hungary from the total energy consumption of the country the building sector, with its 32%, is the biggest energy consumer. In 2006 based on the EU Directive new energy requirements were established for residential, office and educational buildings. In Hungary there are 4 millions of households and more than 50% are placed in detached houses. In the last years different national programs were started in order to encourage the owners to refurbish their buildings.
Reducing the heat demand of the building according to the new requirements the supplied heat amount might be reduced considerably. Having a central heating system with certain heat output of the boiler, certain dimensions of pipes and pumps the adjustment might be done decreasing the supply temperature. But in this case the exergy consumption of these heating systems might be reduced too.
This paper presents the analysis of the refurbishment effects on the heat demand and energy consumption of detached houses built in different periods of time from different materials. Also an exergy consumption analysis is done before and after refurbishing.

description: The characterization of Low Surface Brightness (LSB) stellar structures around galaxies such as tidal debris of on-going or past collisions is essential to constrain models of galactic evolution. Our goal is to obtain quantitative measurements of LSB structures identified in deep images of samples consisting of hundreds of galaxies. We developed an online annotation tool that enables contributors to delineate the shapes of diffuse extended stellar structures, as well as artefacts or foreground structures. All parameters are automatically stored in a database which may be queried to retrieve quantitative measurements. We annotated LSB structures around 352 nearby massive galaxies with deep images obtained with the CFHT as part of two large programs: MATLAS and UNIONS/CFIS. Each LSB structure was delineated and labeled according to its likely nature: stellar shells, streams associated to a disrupted satellite, tails formed in major mergers, ghost reflections or cirrus. From our database containing 8441 annotations, the area, size, median surface brightness and distance to the host of 228 structures were computed. The results confirm the fact that tidal structures defined as streams are thinner than tails, as expected by numerical simulations. In addition, tidal tails appear to exhibit a higher surface brightness than streams (by about 1 mag), which may be related to different survival times for the two types of collisional debris. We did not detect any tidal feature fainter than 27.5 mag.arcsec$^{-2}$, while the nominal surface brightness limits of our surveys range between 28.3 and 29 mag.arcsec$^{-2}$, a difference that needs to be taken into account when estimating the sensitivity of future surveys to identify LSB structures. Our annotation database of observed LSB structures may be used for quantitative analysis and as a training set for machine learning algorithms (abbreviated).

description: Deep learning training involves a large number of operations, which are dominated by high dimensionality Matrix-Vector Multiplies (MVMs). This has motivated hardware accelerators to enhance compute efficiency, but where data movement and accessing are proving to be key bottlenecks. In-Memory Computing (IMC) is an approach with the potential to overcome this, whereby computations are performed in-place within dense 2-D memory. However, IMC fundamentally trades efficiency and throughput gains for dynamic-range limitations, raising distinct challenges for training, where compute precision requirements are seen to be substantially higher than for inferencing. This paper explores training on IMC hardware by leveraging two recent developments: (1) a training algorithm enabling aggressive quantization through a radix-4 number representation; (2) IMC leveraging compute based on precision capacitors, whereby analog noise effects can be made well below quantization effects. Energy modeling calibrated to a measured silicon prototype implemented in 16nm CMOS shows that energy savings of over 400x can be achieved with full quantizer adaptability, where all training MVMs can be mapped to IMC, and 3x can be achieved for two-level quantizer adaptability, where two of the three training MVMs can be mapped to IMC.

description: The indoor temperature and humidity conditions of the building envelope are important parameters for the evaluation of the thermal and hygric indoor comfort.

In the research project GENSIM a new hygrothermal building library, based on the object- and equation-oriented model description language Modelica® has been developed by the Fraunhofer Institutes IBP and FIRST. This library includes many models as for instance a hygrothermal wall model, an air volume model, a zone model, a window model and an environment model. Due to the object-oriented modelling approach, some models of this library can be configured to complex hygrothermal room model, which can predict the time dependent indoor temperature and humidity conditions in a building construction.

In this paper we will introduce in a first step the object-oriented hygrothermal room model of this library. In a second step, the validation of the room model with some field experiments will be shown. In a third step we will present some simulation results, we obtained by coupling the room model with an implemented Predicted-Mean-Vote (PMV) control ventilation system to predict and to ensure a thermal and hygric indoor comfort in one case study.

In the conclusion, the possible range of future applications of this new hygrothermal building physics library and demands for further research are indicated

description: We perform simulations in a gravitational collapsing model using the Einstein equations. In this paper, we review the equations for constructing the initial values and the evolution form of the Einstein equations called the BSSN formulation. In addition, since we treat a nonvacuum case, we review the evolution equations of the matter fields of a perfect fluid. To make the simulations stable, we propose a modified system, which decreases numerical errors in analysis, and we actually perform stable simulations with decreased numerical errors.

description: Models describing the coupled heat, moisture and salt transport in porous building materials require a large number of model parameters. Not all parameters can be experimentally determined with high degree of accuracy and certainty. The article shows the influence of various salt related parameters depending on the application scenario on coupled heat, moisture and salt transport processes. This includes the application of the model to simulate various laboratory experiments. The sensitivity of the main processes examined in the experiments on salt related parameters is shown. The model is also applied to real-life simulation cases.
