description: An dem Modell eines DEMAG-Dreibeinportal-Kranes mit Ausleger im Maßstab 1:36 wurden Luftkraftmessungen im 1,3-m-Windkanal des Institutes für Strömungsmechanik der Technischen Hochschule Braunschweig durchgeführt. Die Stellung des Dreibeinportals zur Windrichtung wurde dabei in der für das Kippen des Kranes ungünstigsten Stellung festgehalten, während der Schwenkwinkel des Auslegers mit Kranhaus sowie der Auslegerwinkel variiert wurden. Es wurden die Luftkräfte auf das gesamte Kranmodell einschließlich Ausleger, sowie auch die Luftkräfte auf dem Ausleger allein gemessen. Die Ergebnisse liefern Unterlagen für statische Lastannahmen der Windkräfte auf den Kran.
description: Measurements of the wind loads on a crane model have been carried out in the 4 feet-wind tunnel of the Institute of Fluid Mechanics of the Technical University of Braunschweig. The scale of the model was 1:36. The crane was of the three legs portal type. In the wind tunnel measurements the position of the crane against the wind direction was fixed in the most unfavourable position with regard to the balance of forces. The turning angle of the crane house with the outrigger against the portal and the angle of inclination of the outrigger have been varied. The six components of the total wind load on the complete model have been measured and also the wind force on the outrigger alone. The results have been used as the basis of the static calculations of the crane under atmospheric wind loads.

description: Kinetic Monte-Carlo (KMC) simulations are a well-established numerical tool to investigate the time-dependent surface morphology in molecular beam epitaxy (MBE) experiments. In parallel, simplified approaches such as limited mobility (LM) models characterized by a fixed diffusion length have been studied. Here, we investigate an extended LM model to gain deeper insight into the role of diffusional processes concerning the growth morphology. Our model is based on the stochastic transition rules of the Das Sarma-Tamborena (DT) model, but differs from the latter via a variable diffusion length. A first guess for this length can be extracted from the saturation value of the mean-squared displacement calculated from short KMC simulations. Comparing the resulting surface morphologies in the sub- and multilayer growth regime to those obtained from KMC simulations, we find deviations which can be cured by adding fluctuations to the diffusion length. This mimics the stochastic nature of particle diffusion on a substrate, an aspect which is usually neglected in LM models. We propose to add fluctuations to the diffusion length by choosing this quantity for each adsorbed particle from a Gaussian distribution, where the variance of the distribution serves as a fitting parameter. We show that the diffusional fluctuations have a huge impact on cluster properties during submonolayer growth as well as on the surface profile in the high coverage regime. The analysis of the surface morphologies on one- and two-dimensional substrates during sub- and multilayer growth shows that the LM model can produce structures that are indistinguishable to the ones from KMC simulations at arbitrary growth conditions.

description: To enable collaboration across the worldwide wind lidar community, we propose a platform for the open-source design, construction, and operation of wind lidar devices, called OpenLidar. OpenLidar is intended to be a research and development platform that can be used by academics, researchers, and equipment developers, rather than replacing existing commercial devices. OpenLidar is based on a modular lidar framework including a laser source, internal optics to form the laser light, some form of telescope and pointing optics to control the laser trajectory, a detector, signal processing equipment, safety interlocks, and communications systems.

description: Electron conduction through quasi-one-dimensional (1D) indium atomic wires on silicon (the Si(111)-4x1-In reconstruction) is clarified with the help of local structural analysis using scanning tunneling microscopy. The reconstruction has a conductance per square as high as 100 uS, with global conduction despite numerous surface steps. A complete growth of indium wires up to both the surface steps and the lithographically printed electrodes is essential for the macroscopic transport. The system exhibits a metal-insulator transition at 130 K, consistent with a recent ultraviolet photoemission study [H. W. Yeom, S. Takeda, E. Rotenberg, I. Matsuda, K. Horikoshi, J. Schaefer, C. M.

description: Recording of flash-ADC traces is challenging from both the transmission bandwidth and storage cost perspectives. This paper presents a configuration-free lossless compression algorithm which addresses both limitations, by compressing the data on-the-fly in the controlling field-programmable gate array (FPGA). Thus the difference predicted trace compression (DPTC) can easily be used directly in front-end electronics. The method first computes the differences between consecutive samples in the traces, thereby concentrating the most probable values around zero. The values are then stored as groups of four, with only the necessary least-significant bits in a variable-length code, packed in a stream of 32-bit words. To evaluate the efficiency, the storage cost of compressed traces is modeled as a baseline cost including the ADC noise, and a cost for pulses that depends on their amplitude and width. The free parameters and the validity of the model are determined by comparing it with the results of compressing a large set of artificial traces with varying characteristics. The compression method was also applied to actual data from different types of detectors, thereby demonstrating its general applicability. The compression efficiency is found to be comparable to popular general-purpose compression methods, while available for FPGA implementation using limited resources. A typical storage cost is around 4 to 5 bits per sample. Code for the FPGA implementation in VHDL and for the CPU decompression routine in C of DPTC are available as open source software, both operating at multi-100 Msamples/s speeds.

description: This dissertation traces the development of Alexander Pushkin's sense of the tragic in the context of Russian and European Romanticism. Pushkin was a self-proclaimed skeptic in matters of literature: though deeply influenced by Romantic poets and theorists, he never subscribed to any one school or creed, experimenting in a range of genres to express his changing tragic vision. Many of his works move seamlessly between the closed world of traditional tragedy and the open world of Romantic tragic drama; and yet, they follow neither the cathartic program prescribed by Aristotle nor the redemptive mythologies of the Romantics. My study explains Pushkin's idiosyncratic approach to tragedy by re-situating his works within their literary, historical, and philosophical contexts. In my readings of The Gypsies, Boris Godunov, and The Little Tragedies, I connect Pushkin's works to those of a range of European writers, including Shakespeare, Racine, Rousseau, Goethe, Schiller, the Marquis de Sade, and Hugo; and I examine such topics as tragedy and the tragic, the sublime and the grotesque, the relationship between literature and history, irony and tragic ritual. While I ground my work in traditional Russian philology, I use recent Western scholarship to help frame my study theoretically. In particular, I aim to contribute to the ongoing debate between scholars who claim that Romanticism marked "the death of tragedy" and those who see the change less as a death than as a redefinition.

description: A method to predict the emergence of different kinds of ordered collective behaviors in systems of globally coupled chaotic maps is proposed. The method is based on the analogy between globally coupled maps and a map subjected to an external drive. A vector field which results from this analogy appears to govern the transient evolution of the globally coupled system. General forms of global couplings are considered. Some simple applications are given.

description: Loss-of-function mutations have provided crucial insights into the immunoregulatory actions of Foxp3+ regulatory T cells (Tregs). By contrast, we know very little about the consequences of defects that amplify aspects of Treg function or differentiation. Here we show that mice heterozygous for an Ikbkb gain-of-function mutation develop psoriasis. Doubling the gene dose (IkbkbGoF/GoF) results in dactylitis, spondylitis, and characteristic nail changes, which are features of psoriatic arthritis. IkbkbGoF mice exhibit a selective expansion of Foxp3 + CD25+ Tregs of which a subset express IL-17. These modified Tregs are enriched in both inflamed tissues, blood and spleen, and their transfer is sufficient to induce disease without conventional T cells. Single-cell transcriptional and phenotyping analyses of isolated Tregs reveal expansion of non-lymphoid tissue (tissue-resident) Tregs expressing Th17-related genes, Helios, tissue-resident markers including CD103 and CD69, and a prominent NF-κB transcriptome. Thus, IKK2 regulates tissue-resident Treg differentiation, and overactivity drives dose-dependent skin and systemic inflammation.

description: The purpose of this thesis is to prove the importance of modern architecture to the evolution of the American college and university campus, and to suggest a course of action with respect to its increased protection through the presentation of case studies that will examine the architectural intention, building performance, public reception and preservation of three mid-century modernist dormitories. The primary case study presents the history and significance of Harvard Law School’s Graduate Center (Walter Gropius and TAC, 1950), and then shows how perceptions of the Graduate Center’s aesthetic and technical failure currently threaten its architectural integrity and future viability. The following section summarizes current discourse in the historic preservation field on the appropriate treatment of modern architecture, both philosophically and physically. The final case studies offer an analysis of recent preservation work done on two modernist dormitories. In the case of MIT’s Baker House, designed in 1949 by Alvar Aalto and renovated by Perry Dean Rogers from 1998 to 1999, MIT’s institutional agenda combined with a consideration for the building’s status as an international icon of modernism produced results both positive and negative for the vitality and integrity of the dormitory. In the case of Ferry Cooperative House at Vassar College, designed in 1951 by Marcel Breuer and renovated from 1999 to 2000 by Herb Beckhard Frank Richlan & Associates, aesthetic intervention was guided by the judgment of Herb Beckhard, former associate of Breuer, and results demonstrated the integral role of the modernist interior. The concluding section highlights important differences in the architecture and status of the three dormitories examined, and summarizes the challenges specific to preserving modernist dormitories.

description: If a first-order phase transition is terminated by collisions of new-phase bubbles, there will exist a period of nonequilibrium between the time bubbles collide and the time thermal equilibrium is established. We study the behavior of the order parameter during this phase. We find that large nonthermal fluctuations at this stage tend to restore symmetry, i.e., the order parameter is smaller than its eventual thermal equilibrium value. We comment on possible consequences for electroweak baryogenesis.

description: Advances in information technology science prompt the creation of new economic models, and one of them in urban life is Sharing Economy. This new economic model has received high attention and has been applied to fields like transportation, hospitality, and other customer-based services in recent years. With the accelerating rhythm of people's life, shared economy flourished unprecedentedly and plays a significant role in business market. However, the overall impact of sharing economy on a country has been little considered. Therefore, the thesis develops an assessment of sharing economy’s impacts in mainland China from varied perspectives. Based on the review of existing scholarly articles, databases, and industrial reports, the thesis discusses what are the impacts introduced by sharing economy to the national economy and relevant industries. While for public perceptions, it employs observations and interviews, with additional help from existing resources, to identify how individuals are being effected. The thesis demonstrates how sharing economy has challenged traditional industries with modified supply-demand relationship. It also illustrates the differences in people’s daily choices in commuting, traveling, lodging, working, and minor behaviors, and public optimistic appreciation towards sharing economy. Yet, the thesis recognized the existence of issues like legality, safety, security, and sustainability, which require democratizing the ownership and governance of the platforms, with an effective and systematic design for long-term regulation and development.
Putting the Citizen at the Heart of Water Management: A Study of Water in Bangalore

Publisher: name: Columbia University

Subjects: Water resources development--Management
Water harvesting

description: The focus of this thesis is the innovative process by which citizens in Bangalore, India have become engaged with the problem of water management through rainwater harvesting. Bangalore currently faces a water shortage of 500 million liters per day and, unless it dramatically changes its approach, acute water shortage by 2025. An effective water management scheme in Bangalore requires institutional restructuring to enable integrated management of water resources, strong legislation to protect groundwater, major infrastructural improvements to limit leakage, a shift in planning culture that more explicitly recognizes the link between the natural world and human settlements and stronger integration of science in planning. It is clear that any one of these actions is not easily implementable in the near term due to institutional, financial, and political challenges. In the absence of any near-term solutions for the water crisis, civil society has played a critical role in pushing the local water authority to make rainwater harvesting mandatory through the Bangalore Water Supply and Sewerage (Amendment) Act, 2009. This thesis aims to add to two larger theoretical discussions: governing the commons and finding innovative solutions and processes for resource management. Governing the commons, especially in the dynamic context of rapidly growing cities that face systemic scarcity, requires a strong state to effectively restrict wasteful practices and mining of resources and a strong civil society to curb demand. As such, the scarcity-induced innovation framework (Srinivas and Sutz, 2008) has been applied to identify rainwater harvesting as an innovative approach to engage citizens in the heart of water management and curb demand. Rainwater harvesting is not presented here as a panacea, nor is it meant to distract from the need for the state to play a much stronger regulatory and implementation role.

description: We present the design and implementation of an automated data calibration and reduction pipeline for very-long-baseline interferometric (VLBI) observations taken at millimeter wavelengths. These short radio-wavelengths provide the best imaging resolution available from ground-based VLBI networks such as the Event Horizon Telescope (EHT) and the Global Millimeter VLBI Array (GMVA), but require specialized processing due to the strong effects from atmospheric opacity and turbulence as well as the heterogeneous nature of existing global arrays. The pipeline builds upon a calibration suite (HOPS) originally designed for precision geodetic VLBI. To support the reduction of data for astronomical observations, we have developed an additional framework for global phase and amplitude calibration which provides output in a standard data format for astronomical imaging and analysis. We test the pipeline on observations taken at 3.5 mm (86 GHz) by the GMVA joined by the phased Atacama Large Millimeter/submillimeter Array in April 2017, and demonstrate the benefits from the specialized processing of high frequency VLBI data with respect to classical analysis techniques.

description: This thesis comprises eight chapters in two parts: the first part, chapters 1 to 6, details the design, synthesis, self-assembly and electrical properties of a new class of contorted polyheteroaromatic molecules, and the chapters 7 and 8 in the second part describes the design and fabrication of the first nanoscale field-effect transistor for single-molecule kinetics study.
      		Chapter 1 is an introductory chapter. It first introduces the concept of organic photovoltaics (OPV), including the operation principles, important parameters, device structures, and relevant studied small molecules for the active layer in OPV devices. The second part of the chapter will be an overview of single-molecule biosensors involving various techniques and some important aspects on the design and fabrication. Chapter 2 details the development of a new synthetic methodology for polyheteroaromatic compounds. As one example, contorted dibenzotetrathienocoronenes (c-DBTTC) have been efficiently synthesized in three steps with high yields (>80%). Importantly this class of molecules displays an unusual intermolecular stacking in solid state and intimate interaction with n-type materials (TCNQ and C60) due to their shape-shifting ability. Chapter 3 will describe an unusual molecular conformation in highly fluorinated contorted hexa-cata-hexabenzocoronenes (c-HBC) via the fluorine-fluorine repulsive interaction. Chapter 4 describes the self-assembly properties of a new class of materials, chalcogenide-fused c-DBTTC, investigated by grazing incidence X-ray diffraction (GIXD), fluorescence microscopy and scanning electron microscopy (SEM). In chapter 5 a reticulated heterojunction OPV device applying c-DBTTC as the p-type active layer will be detailed. Combining the excellent self-assembly of c-DBTTC with the patterned graphene electrodes gives improved field-effect mobility in devices and will be described in chapter 6.
      	In chapter 7, a field-effect transistor using a carbon nanotube (CNTFET) will be introduced. DNA hybridization kinetics will be detected using this "label-free" nanoscale device that represents a breakthrough in the field of single-molecule techniques by delivering high sensitivity and bandwidth. In chapter 8, a basic scientific research concerning Debye screening in buffer solution will be demonstrated utilizing above-mentioned DNA devices. Again, this nanoscale device uses its ability of single-molecule detection to correlate Debye length with buffer concentrations and charge distances, respectively; the correlations will serve as important references for the design of nanoscale biosensors using carbon nanotubes.
Investigation into the migration of Leishmania within Phlebotomine sand flies
Creators: name: Kumordzi, Yasmine
Publisher: name: Lancaster University
Year: 2019

description: Protozoan parasites of the genus Leishmania are the causative agents of a wide spectrum of diseases from self-healing cutaneous leishmaniasis to visceral leishmaniasis. The parasites undergo a complex life cycle including motile and nonmotile cell types within the insect vector and vertebrate host. Within the insect vector, promastigotes generally migrate anteriorly along the gut as they undergo morphological changes from procyclic to nectomonad and later to metacyclic form of promastigotes. In order for the insect vector to transmit infective stage Leishmania promastigotes to the mammalian host via a blood feed, metacyclic promastigotes need to be located within the foregut. The study of the elicitors of migration within the sand fly alimentary canal have to date been fragmentary with no exploration of the different promastigote forms and the effects of the vast array of potential chemoeffectors present. Two Leishmania species were selected based on their migration properties in the sand fly gut. This study focussed on understanding the chemotaxis of different morphotypes of posterior migrating reptilian- pathogenic Leishmania tarentolae compared to the anterior migrating human pathogenic Leishmania mexicana within the biochemical gradients of the sand fly alimentary canal. This study explored the movement of both L. mexicana and L. tarentolae promastigotes towards a gradient of urea that may be found emitting from Malpighian tubules in the hindgut, the novel morphologies of L. tarentolae, the migration of procyclics, neptomonads, leptomonads and metacyclics, and the development of a novel microfluidic device for the study of chemotaxis in Leishmania. The results from the chemotaxic assays suggested that the migration of promastigotes occurred through the attraction towards cues such as the urea gradient from the Malpighian tubules and hindgut, and the sugars gradient from the diverticulum. These assays showed that L. tarentolae had a significantly higher attraction to urea and L.mexicana to sugars; confirming the species-specific differences between suprapylarian and hypopylarian parasites. Using different populations of L. mexicana and L.tarentolae promastigotes, a significant difference in migration between population based on age was observed. The results also suggested that a population rich in leptomonads and nectomonads had a higher migration and therefore a higher attraction towards the chemical cues. The results shed light on parasite migration that is dependent on the developmental stage of promastigotes as well as the speciesspecific cues. The role that the cues play in determining which Leishmania species can be transmitted via the bite of a sandfly are discussed.

description: The design of a construction in a new material is a very difficult task, because of the complexities of design requirements, on the one hand, and the peculiar properties of most high strength materials, on the other hand. It is now practically impossible to integrate the three different types of endeavor which lead to a successful design, namely the experimental procurement of design data and laws, their mathematical evaluation, and the utilization of these efforts by the designer. Therefore, a great need exists for specific experimentation aimed at establishing the material behavior under conditions incorporating one or several service variables. Examples of such work, combining service and laboratory tests, are described, which relate to different design efforts, namely: the simulation of service conditions for super-high strength steels by means of the notch tension test; the surface rolling of steel and magnesium and the specific conditions to be maintained, hereby, in order to arrive at maximum strength. The calculation of the service life of turbine buckets, based on stress rupture tests. Modell tests with lead and other low melting metals to arrive at the load-carrying capacity, as well as at forging conditions, for high melting metals.

description: We have recently calculated shot noise for entangled and spin-polarized electrons in novel beam-splitter geometries with a local Rashba s-o interaction in the incoming leads. This interaction allows for a gate-controlled rotation of the incoming electron spins. Here we present an alternate simpler route to the shot noise calculation in the above work and focus on only electron pairs. Shot noise for these shows continuous bunching and antibunching behaviors. In addition, entangled and unentangled triplets yield distinctive shot noise oscillations. Besides allowing for a direct way to identify triplet and singlet states, these oscillations can be used to extract s-o coupling constants through noise measurements. Incoming leads with spin-orbit interband mixing give rise an additional modulation of the current noise. This extra rotation allows the design of a spin transistor with enhanced spin control.

Development of international standards for mine reclamation management
Creators: name: Steenhof, P. A.
Publisher: name: The University of British Columbia
Year: 2016

description: A new international standards work program is underway through the International Organization for Standardization (ISO) to develop a series of international standards that will provide requirements and recommendations for mine reclamation management, with a focus on reducing the environmental risks, associated financial liabilities and environmental impacts of mining. Nine countries are actively participating in the standards development program, including all of the most significant mining countries in the world. CSA Group has helped organise a committee of Canadian stakeholders and experts from the Canadian mining industry, relevant government authorities, service providers, and academic researchers with the mandate to provide Canadian leadership and input into this international standards program. This article explains the international standards being developed for mine reclamation management with a focus on an international work item and international standard that Canada has proposed on the topic of mine reclamation management planning. The standard is intended as a crucial overarching document that will provide requirements or recommendations on the topic of mine reclamation management planning. The document will also help guide the development of related standards for the mine reclamation management process. The work item follows a lifecycle approach to mine reclamation management planning and recognises that planning for mine reclamation must take place throughout the lifecycle of the mine and not just at closure. This paper covers the main decision points and procedures that need to be considered in planning for mine reclamation, organised around the following topic areas: approaches to reclamation, reclamation technologies, reclamation activities, reclamation monitoring, financial provisions, and documentation and reporting. The objective is that the ensuing standard will help ensure consistency and completeness in terms of the mine reclamation planning process.

For q\equiv 1\pmod{4}, q\geq 17, the Fermat curve of equation x^{(q+1)/2}+y^{(q+1)/2}+1=0 is the unique F_{q^2}-maximal curve of genus g=(q-1)(q-3)/8. For q\equiv 3\pmod{4}, q\ge 19, there are exactly two F_{q^2}-maximal curves of genus g=(q-1)(q-3)/8, namely the above Fermat curve and the non-singular F_{q^2}-model of the plane curve of equation y^q+y=x^{(q+1)/4}. The above results provide some new evidences on maximal curves in connection with Castelnuovo's bound and Halphen's theorem, especially with extremal curves; see for instance the conjecture stated in Introduction.

Putting Smell in Its Place: The Categorization of Odor Preservation Projects
Creators: Clevenger, Justin
Publisher: name: Columbia University
Year: 2018
Subjects: Historic preservation
Odors
Sensory evaluation

description: Preservationists, starting in the late twentieth century, have put the idea to practice that the smell of an object, place, event, or person can be worthy of preservation and considered culturally significant. This is a recent shift in a discipline that was previously focused on physical objects such as buildings, monuments, and art as the only entities that were considered to be worthy of preservation. Preservation theory therefore developed theories of authenticity that do not capture or are unable to judge smell. This thesis will fill an important gap in the heritage discourse by providing a critical framework for judging the level of authenticity in olfactory preservation projects. I examined key examples of scent preservation including Colonial Williamsburg (1926), the Dennis Severs House (1999), the Japanese Ministry for the Environment’s 100 Most Fragrant Landscapes List (2001), and my own Morgan Library Odor Recreation (2017). I provide an analytical framework for judging the level of authenticity of smell preservation projects, consisting of eight categories including sourcing, significance, fabrication, location, intention, duration, evidence, and aesthetics. While each of the aforementioned case studies utilize odors in some manner, each of them does so very differently with a different intent. In every instance where case studies have been analyzed and historical records have been created no one has attempted to categorize them. The intent of this thesis is to arrive at such a framework through the analysis of key olfactory preservation projects by providing a framework for judgement. I hope to provide a theoretical foundation for future practices in management, design, and interpretation of odor preservation projects.
Quantum phase transition inside the superconducting dome of Ba(Fe$_{1-x}$Co$_x$)$_2$As$_2$ probed by optical magneto-sensing using NV-centers in diamond

description: While unusual normal state properties, such as non-Fermi liquid behavior of the resistivity, are commonly associated with strong quantum fluctuations, evidence for its presence inside the superconducting dome are much scarcer. In this paper, we use sensitive and minimally invasive optical magnetometry based on NV-centers in diamond to probe the doping evolution of the $T=0$ penetration depth in the electron-doped iron-based superconductor Ba(Fe$_{1-x}$Co$_x$)$_2$As$_2$. A non-monotonic evolution with a pronounced peak in the vicinity of the putative magnetic QPT is found. This behavior is reminiscent to that previously seen in isovalently-substituted BaFe$_2$(As$_{1-x}$P$_x$)$_2$ compounds, despite the notable differences between these two systems. Whereas the latter is a very clean system that displays nodal superconductivity and a single simultaneous first-order nematic-magnetic transition above, and even somewhat below, $T_c$, the former is a significantly dirtier system with fully gapped superconductivity and split second-order nematic and magnetic transition above $T_c$. Thus our observation that such distinct systems display remarkably similar penetration depth peaks, combined with the theoretical result that a QPT alone does not ensure the existence of a peak, unveils a puzzling and seemingly universal manifestation of quantum fluctuations in the iron pnictides.

description: Im Jahre 1956 wurde von der Stadt Braunschweig ein Architekturpreis gestiftet als Auszeichnung besonders gut gelungener zeitgenössischer Bauwerke und deren Architekten. Er trägt den Namen von Peter Joseph Krahe, dessen 200. Geburtstag sich 1958 jährt.
Krahe hat in Braunschweig von 1803 bis zu seinem Tode im Jahre 1840 gewirkt. Seine Bedeutung als Architekt geht weit über die Grenzen der Stadt hinaus. Als Persönlichkeit mit hoher Bildung und Weltkenntnis ist er der Prototyp der Goethezeit. Seine Entwürfe und zahlreich erhaltenen Bauwerke zeigen ein unbestechliches Gefühl für Maß, Proportion und Funktion. Sie wurden zu Beispielen von zeitloser Gültigkeit. Seine geniale städtebauliche Leistung aber, die Gestaltung der Braunschweiger Wallanlagen, macht Krahe zu einem der führenden Baumeister seiner Zeit.
description: In 1956 the local authorities of the City of Brunswick established a prize for architecture as an award for contemporary buildings of outstanding merit and their architects. It bears the name of Peter Joseph Krahe, the 200th anniversary of whose birthday will come to pass in 1958.
From 1803 to his death in 1840 Krahe worked in Brunswick. His importance as a builder went far beyond the confines of the city, and his universality of knowledge and education made him a typical representative of the classical period of German arts, the time of Goethe. His designs as well as the numerous buildings of his still surviving bear witness to his intuitive knowledge of balance, proportion, and structure. They were to set a standard to later times. His most original achievement in town-planning, the transformation of the city fortifications into a green belt of parks, made Krahe one of the leading architects of his time.
