Foundations for the Analysis of Surreal-Valued Genetic Functions

description: In this thesis we systematize earlier results from the literature of functions on surreal num- bers and consider the generalization of results of Ehrlich and van den Dries regarding models of real-closed fields with exponentiation to the wider class of genetic functions, which includes many examples of interest such as the class of restricted analytic functions, exp, and log, as well as the ω map and other recursively definable functions. We do so by first amending the construction of arbitrary genetic functions found in the literature, so that we may properly compose functions, and so that one can easily recover the definition of exp. We then analyze our newly proposed inductive construction with two natural notions of complexity - that of generation, which tracks the dependence on earlier genetic functions, and that of Veblen rank, which describes the complexity of subtrees closed under a genetic function - in order to characterize the ordinals α such that the surreal numbers below height α will correspond to models satisfying the cofinality conditions and the axioms of real closed fields. After recovering fundamental analytic results for general surreal-valued functions, we further prove that every genetic function has a Veblen rank corresponding to an ordinal, and that our notion of Veblen rank behaves well under addition, multiplication, and composition, and in turn can be extended to arbitrary sets closed under said operations. In particular, the Veblen rank of a genetic function g identifies the largest subclass of epsilon numbers α such that sets of surreal numbers of height below α form a real closed field closed under g. From this, we establish many important functions, such as exp and log will have minimal Veblen rank, while the lambda and kappa maps used to define the Berarducci-Mantova derivative have non-trivial Veblen rank. As a further consequence of our Veblen rank bound, we establish that every entire genetic function is strictly tame in the sense of Fornasiero [4]. Afterwards, with G denoting a set of genetic functions, we proceed to define a general first order theory whose models are G-closed fields satisfying fundamental first order properties used to define each genetic function.

description: This paper presents a simple building simulation tool for integrated daylight and thermal analysis. The tool is capable of importing the thermal and visual properties for different glazings and shading positions from the Window Information System (WIS) program. Combined ray-tracing and radiosity methodology is used to derive the daylight levels for different sky conditions on an hourly basis. The daylight levels are fed into an existing simple thermal simulation program capable of calculating energy demand and the indoor environment. Straightforward control systems for general and task lighting systems have been implemented together with a shading control strategy that adjusts the shading according to the indoor operative temperature and the profile angle of the sun. The implemented daylight calculation method allows for shades from the window recess and overhang, and for distant shades blocking the sky vault. Comparisons with the ray-tracing program Radiance show that the accuracy of this approach is adequate for predicting the energy implications of photoresponsive lighting control. The amount of input is small, which makes the tool useful for integrated daylight optimisation in the early design process.

description: Sustainable development includes social and environmental as well as technical aims. In construction, eco-efficiency emphasises the properties of the building, achieved by technical means to fulfil the social and environmental aims. Functionality and adaptability of the interior and indoor comfort are often the key issues  for users of a building. Energy and material flows during the use of a building compose a major part of the life cycle energy resource use and environmental pressure.

Housing projects ranging from social housing to visions of modern architecture and living in the future  were designed and constructed to demonstrate that both user satisfaction and low total environmental pressure can be achieved by building in steel. On the technical level, new innovations of light gauge steel including new structural systems and utilisation of solar energy were demonstrated.

It was also shown, that major improvements in environmental  properties of a building  are possible without much increasing the investment costs. By increased service life of building components, adaptability and functionality of the interior, whole building design for energy and durable structural system and easiness of maintenance and renovation the life cycle costs can be significantly reduced compared to a normal building with the same architectural form and size.

description: Performance approach aims at management of a product's life cycle properties, and benefit for the users. In eco-efficient construction, performance is an output value achieved with certain input by environmental impacts and life cycle costs. Market driven life-cycle optimised construction has to fulfil three major requirements. A performance that fulfils the user requirements for extended periods should be the output from the design and construction process.  Low environmental pressure and low life cycle costs are the input needed to fulfil the requirements. As decision-making is often based on first costs, the building's technical solutions need to be cost-effective.
Based on performance requirements set for indoor climate, comfort and adaptability to user's varying needs on one hand and requirements on first costs, life cycle costs and environmental impacts on the other, a model house introducing a new wooden structural system was designed. The architectural challenge of the model house comes from the high adaptability of interior and exterior spaces including a possibility to expand the house according to future needs.
The analysis of the model house shows 60% reduction of heating energy consumption and 30% reduction of life cycle costs compared to a typical house. According to call for tenders, the investment costs are on the level of a typical house.
The building introduces a new open wood-framed building system Nordic Platform allowing for shorter delivery cycle than with typical site-construction. The system aims at site-construction from pre-fabricated products for building envelope. The open construction system with published structural details is free to be copied by other network actors. As the basic principle of the construction process is to utilise local enterprise networks, resources and labour, education for both producers of building products and site-workers is needed.
Special features of the system are 250 mm single-frame wooden structure with integrated thermal break for exterior walls and trussed construction for internal floors. The house has a mechanical ventilation system with heat recovery. Two heating systems are introduced: floor heating and ventilation heating system. The house is also designed for regional construction and distributed energy supply. Trussed floors include a possibility for easy and flexible installation and maintenance of building services systems.

description: Urban stormwater has a significant problem because it contains excessive nutrients harmful to the environment. According to the United States Environmental Protection Agency (2012), phosphate and nitrate are the most polluted nutrients in the United States. It harms the ecosystem, biodiversity, and human health. One way to prevent these nutrients from entering the body of water is through a system called bioswale, which consists of porous media such as BOF slag and biochar. These materials are tested to find their capacity to filter nitrate and phosphate. The methods used to test the capacity of BOF slag and biochar are column tests, batch tests, and swelling tests of BOF slag. The column tests results for nitrate removal are 63 mg/kg for BOF slag and 229 mg/kg for biochar. The results show a similar trend for phosphate removal in column test with 25 mg/kg for BOF slag and 150 mg/kg for biochar. In contrast, the batch tests results are 60 mg/ kg for BOF slag and 437 mg/kg and biochar for nitrate removal, and the results for phosphate removal are 317 and 232 mg/kg for BOF slag and biochar, respectively. Finally, the swelling tests found that the overburden stress from the topsoil is sufficient to overcome the swelling with 0.31 percent of volumetric strain in 84 days. It is recommended to test field stormwater using batch tests and column tests with similar nutrients. Furthermore, a pilot-scale study is needed to test the performance of BOF slag and biochar under real-world conditions.

description: Past decades tightening of building regulations with regard to energy consumption have reduced the heat loss through the building envelope and the buildings have become more airtight. The importance of having a well designed and functioning ventilation strategy in new buildings is therefore essential in obtaining an acceptable indoor air quality and avoiding damage to the building due to mould growth etc.
The EU directive on the energy performance of buildings has been introduced to promote improved energy performance of buildings taking into account the outdoor climate and local conditions, as well as the indoor environment requirements and cost effectiveness.
Ventilation of the building takes up a considerable amount of a buildings energy consumption however research have showed that it is possible to reduce the energy loss by ventilation when using a demand controlled ventilation (DCV) system in residential buildings.
Analysis of a DCV system in residential buildings will be performed, and the paper will present the investigations and discuss aspects of DCV systems with regard to air quality and energy savings.
Passive houses for a cold climate

description: Passive house refers to a specific construction standard for residential buildings with good comfort conditions during winter and summer, without traditional heating systems and without active cooling. Typically this includes very good insulation levels, very good airtightness of the building, whilst a good indoor air quality is guaranteed by a mechanical ventilation system with highly efficient heat recovery. The properties of the Finnish passive house were defined by VTT in the  European research project Promotion of European Passive Houses (PEP)  funded by Intelligent Energy Europe program in FP6:
•	the total primary energy use for appliances, domestic hot water and space heating and cooling is limited to 130 – 140 kWh/m2,
•	the total energy demand for space heating and cooling is limited to 20 - 30 kWh/m2 floor area;
•	the airtightness of the building envelope n50 ≤ 0,6 1/h

The energy demand is defined to be higher than the corresponding demand in Central Europe. Energy simulations have shown that a Passive house in the climate of Central Finland would require insulation thicknesses of 50 - 60 cm in exterior walls, 70 - 80 cm in the roof, and roughly 40 cm in the floor to fulfill the Central European requirement. At the same time window area should be minimized, and the window U-value should be less than 0,5 W/m2K. The economic viability of such a building is rather low, and thus the Central European definition is not justified.

Thick insulation layers necessitate special attention to be paid to the performance of the structures. frost protection of foundations, drying capacity of insulated structures, avoidance of thermal bridge effects, and long term performance of the airtight layers need to be considered. The concept development and construction of the first Finnish Passive houses tackled these challenges.

Experiences on ventilation heating systems show that simple heating systems are viable also in the cold climates. The increased heating power demand compared to climates in Central Europe does not reduce the indoor air quality. Room based control enables varying room temperatures according to specific needs of the users.

description: The present work focuses on learning how to use the hardware and software of a Time-of-Flight camera and then creating C++ programs that try to lay the basis for future ones that would be implemented in bigger applications that are able to tackle and solve the most common problems related to 3D machine vision. All the code and programs present in the thesis are born and developed with the key idea in mind that they can provide a foundation for future work as the starting point for more complex projects related to 3D computer vision and thus be implemented in applications such as bin-picking, autonomous driving, quality inspection and so on. The C++ programs developed in this thesis, along with smaller questions, address four main problems in the field of computer vision: Registration, CAD model creation, Segmentation and Object Recognition. Registration consists of aligning various 3D point clouds taken from different points of view of the same object so as to reconstruct a full 3D model of the object. CAD model creation is usually the step following Registration and it consists in creating a 3D mesh of the registered object. This mesh can be exported in AutoCAD or any other 3D CAD software to perform further studies and analysis on the object. Segmentation consists of dividing point clouds in multiple parts and pieces, which can be then studied independently. Finally, the last topic studied and developed in the thesis is Object Recognition, which consists in the ability to locate and recognize objects from a 3D point cloud.

description: If one takes a closer look at almost any building facade one will find biological growth. Although this can be seen as an integral part of an antique building, for modern buildings it is in most cases seen as an aesthetical problem. All building facades will most likely be discolored by biological growth by time, but in Sweden we have seen many cases of newly built rendered facades that have been discolored much more rapidly than usual. The problem is believed mostly to occur on thin rendering applied on thermal insulation - which is a common building facade construction in Sweden - but apart from this, it is difficult to find clear indications of which facades that will be affected. As it is well known that different biological organisms has different requirements in physical factors (especially temperature and relative humidity) for germination and growth on any substrate, it is important to define which conditions the organisms needs to grow on a building fasade. We have studied the temperature and relative humidity conditions on the surfaces of different rendered facade constructions as a start to investigate why we has such a enormous problem with growth on newly builded thin rendered facades in Sweden. We find that the surface temperature on a facade of thin rendering on thermal insulation drops quickly during nights, as these constructions have low heat capacity in the rendering layer. This leads to high relative humidity and condensation on the surface, especially during clear nights. Other abiotic factors that seems also to influence the risk for growth are surface color and rendering structure. We have also made simulations of the surface climate on a building facades in order to fully understand the rendered facade as a biological habitat.

description: Miller Range (MIL) 07687 is a peculiar carbonaceous chondrite officially classified as a CO3. However, it has been found to display unique petrographic properties that are atypical of this group. Moreover, Raman spectra of its polyaromatic carbonaceous matter does not reflect a structural order consistent with the metamorphic history of a type 3 chondrite. As a result, it has been suggested to be an ungrouped C2 chondrite with CO affinities, although it has not been fully excluded as a CO chondrite. The ambiguity of the meteorite classification is the motivation behind the present study. We conclude that MIL 07687 is a unique carbonaceous chondrite with possible affinities to CO, CM and/or some ungrouped carbonaceous chondrites. The difficulty in classifying this meteorite stems from (i) its heavily weathered nature, which interferes with the interpretation of our oxygen (O-)isotopic measurements (ii) the overlap in the petrographic and O-isotopic descriptions of various COs, CMs and ungrouped meteorites in the Meteoritical society database. Optical and infrared spectra are consistent with the meteorite unequilibrated nature and indicate that it is probably mildly aqueously altered. Despite traces of aqueous alteration having previously been described in MIL 07687, this is the first time that the presence of hydrated amorphous silicates is reported. In fact, our results show that its present hydration is beyond that of most CO3s, less than most CM2s, and comparable to primitive CR2s. Consequently, we support the meteorite s C2 ung label, although a CO2 or CM2 classification cannot be fully excluded.

Subjects: Uncategorized

description: Investigating electrocatalytic routes to upgrade prevalent greenhouse gases (GHGs) like CO2 and CH4 offers opportunities for sustainable manufacturing of value-added commodities (e.g., C2H4, CH3OH). Moreover, the availability of "cheap electrons" makes this route more attractive. It opens the potential to achieve a high reaction rate, high control over product selectivity, relatively milder operating conditions, and an excellent avenue for large-scale industrial applications. The central focus of this work is to advance experimental and computational methods to develop highly efficient electrochemical systems for CO2 capture, clean energy production & storage and to understand the dynamics at the electrode-electrolyte interface to gain mechanistic insight into sustainable electrochemical reactions. This work describes the prototyping of such electrochemical systems for capturing CO2 and converting CO2 & CH4 to fuels and value-added products. It encapsulates a combination of experimental and computational approaches in setting up an electrochemical system involving syntheses and characterization of electrocatalysts, designing & fabricating electrochemical reactors, fundamental insights into reaction mechanisms, and accessing the scope of scaling up such processes.

description: Numerical models can be used to evaluate design and upgrade scenarios of urban wastewater systems on the basis of their ecological consequences. The objective of this paper is to illustrate a systematic procedure of system design/upgrade. This procedure consists of the following steps: 1) data collection and data reconstruction, 2) model building and calibration, 3) evaluation of scenarios, 4) uncertainty assessment. In contrast to conventional practice, this approach allows to choose the most appropriate trade-off between cost of measures and risk of non-compliance with regulatory limits. An example of its application dealing with the assessment of WWTP design and upgrade options is provided. Results show that by reducing the tank volumes compared to conventional design procedures, costs can be reduced sensibly while the risk of not meeting legislative requirements are only slightly increased.

description: The present work describes the in-progress activities devoted to the definition of a model of sustainable management of the water resources at local scale, with special reference to an Optimal Territorial Ambit (ATO). These activities partly take as a starting point the EPSILON international research project \342\200\234Environmental Policy via Sustainability Indicators On a European-wide NUTS-III level\342\200\235. The objective of such a model is to overcome the current DPSIR (Driving force-Pressure-State-Impact-Response) approach, allowing to create an ISST (Sustainability Synthetic Territorial Index), which is a composite indicator obtained from elementary indicators of environmental, economic, social and institutional nature, subsequently aggregated in sub-themes, themes and pillars. The 155 Municipalities constituting the ATO can then be clustered in 5 categories (very low, low, middle, high, very high), according to the value of the corresponding composite sustainability indicator. Thanks to this approach, several classes of users can simulate different sustainability scenarios relevant to different values of the elementary indicators. In particular, the identification of sustainability indicators for the management of water resources allows a quick assessment of the management actions to be activated for the water use and reuse, with reference to the different uses and the different aspects of the Integrated Water System.

description: The controlled introduction of covalent sp$^{3}$ defects into semiconducting single-walled carbon nanotubes (SWCNTs) gives rise to exciton localization and red-shifted near-infrared luminescence. The single-photon emission characteristics of these functionalized SWCNTs make them interesting candidates for electrically driven quantum light sources. However, the impact of sp$^{3}$ defects on the carrier dynamics and charge transport in carbon nanotubes remains an open question. Here, we use ultrafast, time-resolved optical-pump terahertz-probe spectroscopy as a direct and quantitative technique to investigate the microscopic and temperature-dependent charge transport properties of pristine and functionalized (6,5) SWCNTs in dispersions and thin films. We find that sp$^{3}$ functionalization increases charge carrier scattering, thus reducing the intra-nanotube carrier mobility. In combination with electrical measurements of SWCNT network field-effect transistors, these data enable us to distinguish between contributions of intra-nanotube band transport, sp$^{3}$ defect scattering and inter-nanotube carrier hopping to the overall charge transport properties of nanotube networks.

description: The aim of this study was to evaluate the influence of the city of \303\226rebro, where it is no com-bined sewers, on pollution load to the receiving water the river Svart\303\245n. GIS and hydrologic modelling was used to achieve this. The subcatchments in the city that accounted for the highest discharges of pollutants was identified and measures to reduce the load from these subcatchments was proposed. It was shown that stormwater was the most important source of heavy metals to Svart\303\245n, but the influence of stormwater on the nutrient load was negligible. Further, one stormwater discharge was identified that accounted for about 1/4 of total pollu-tion load from storm-water on Svart\303\245n. Even if this subcatchment yielded the highest amount of pollutants, the highest concentrations was found from small homogeneous catch-ments. It was concluded that studies like this could be a valuable tool in the stormwater management.

description: Excerpts from the report: Since 1962, the Federal Government has encouraged development of recreation enterprises on farms and other rural lands as (1) a way to provide additional income to rural families, (2) a use for unused or underutilized rural resources, and (3) a source of increasingly needed recreation opportunities for nonfarm people. Both public officials and private investors expressed interest in opportunities for developing outdoor recreation facilities and services on farms and in rural areas of Appalachia. The contrasting ridges and valleys of Appalachia make it one of the most potentially interesting and scenically attractive areas in America. Some people assumed that improved transportation, lacing the Region with new highways, would provide needed access from urban areas bulging with people wanting recreation outlets. Improved access was assumed to help get potential recreation users and potential suppliers together in rural mountain areas. Five popular types of privately owned recreation enterprises (vacation farm, riding stable, hunting area, fishing area, and campground) were studied to provide insight into the situation in Appalachia. The 86 recreation operations studied were drawn from a nationwide survey conducted by the National Association of Conservation Districts cooperating with the Soil Conservation Service.

description: Infiltration systems divert urban stormwater away from the surface runoff path, acting to temporarily store and then infiltrate it into the surrounding soils. However, these systems have a very high failure rate due to clogging. Research is being conducted at Monash University to develop a fundamental understanding of clogging processes and to develop a new clogging prediction method for stormwater infiltration systems. This paper presents the method and results of the preliminary experiments carried out on a one dimensional rig. The experiments were conducted in order to investigate transport of sediment particles in stormwater through the filter media and soil underneath it, by simulating vertical flow through typical infiltration systems. Both constant and fluctuating stormwater levels in the system were studied to examine the effect on the clogging process. It was found that a clogging layer will form on the interface between the filter medium and soil. If the water level in the system is held constant, a large percentage of the sediment concentrates around that water level. This has important implications on modeling of clogging in systems that do not empty completely.

Biomimetic Model Systems of Aerobic CODH and Computational Insights on Its CO Oxidation Mechanism

description: The carboxydotrophic bacteria plays a key role in the global carbon cycle by catalyzing two-electron/two-proton interconversions of CO and CO2 to provide energy and the carbon source during chemolithoautotrophic growth using carbon monoxide dehydrogenase (CODH) enzymes. One of two known CODH variants contains a catalytic Mo/Cu cofactor whose MoVI–(µ2-S)–CuI active site has no synthetic or biological precedent and whose chemical mechanism for CO oxidation is under debate. Constructing synthetic models for this unusual inorganic functional group is a long-standing challenge and could contribute valuable insights regarding structural and functional aspects of the cofactor. Here, I will discuss the synthesis and characterization of (bdt)(O)(X)WVI–(µ2-S)–CuI(NHC) complexes (bdt = benzenedithiolate, X = O or OSiiPr3, NHC = a N-heterocyclic carbene) that faithfully mimic the structure of the (MCD)(O)(X)MoVI–(µ2-S)–CuI(SCys) cofactor in CODH (MCD = molybdopterin cytosine dinucleotide, X = O or OH, SCys = cysteine). In our findings we disclose that, in the absence of a protein environment, the core takes on an unreactive “closed” form in which an acute µ2-S angle enforces a short metal-metal distance and a close contact between the CuI center and either the bdt or X ligand. By contrast, the native cofactor features an active “open” form in which an obtuse µ2-S angle keeps the metal centers apart and the CuI site unsaturated. We used DFT calculations to estimate the strain energy required to open the synthetic model’s µ2-S angle, thus estimating the contribution of the CODH secondary structure towards cofactor activity. These observations support a mechanistic hypothesis wherein the Mo/Cu cofactor activates CO by virtue of a frustrated Lewis pair contained within the active site and enforced by the protein scaffold. We anticipate that our study will enrich hypotheses about biochemical multi-electron/multi-proton reactions as well as synthetic design of multimetallic catalysts.
