description: The semantic segmentation of very high resolution (VHR) remotely sensed images is to assign a categorical label for each pixel, which is an important but unsolved problem in remote sensing. In recent years, fully convolutional networks (FCN) have become the state-of-the-art framework for the semantic segmentation in computer vision. Thus, this work aims to improve the semantic segmentation of VHR images by utilizing FCN. Firstly, we propose a promising framework which achieves the top result (90.6%) on the ISPRS Vaihingen benchmark. In the framework, the proposed FCN-based network obtains a competitive result (90.1%). In addition, we develop the DSM backend to enhance the result of FCN by incorporating complementary information from color images and digital surface model (DSM). Secondly, we propose the recurrent FCN for modeling the continuous context inherent in VHR images. Experimental results demonstrate that the recurrent FCN significantly boosts the performance of FCN by incorporating the local contextual information from patches and the global contextual information between patches.

Taraxacum oblongatum besitzt schwarzgrüne Hüllen und schmale, unberandete, zurückgerichtete, schmutzig-violette äußere Involukralblätter, rosafarbene Blattstiele und auffällig hakenförmig gebogene Blattseitenlappen.
 Insbesondere die dunklen Hüllen weisen auf eine Verwandtschaft mit T. amaurolepis hin, dem es sehr ähnelt, sich von diesem aber durch hakenförmig gebogene Blattseitenlappen sowie einen kleineren Blattendlappen unterscheidet. Taraxacum oblongatum hat eine weite Verbreitung in Nordeuropa und im nördlichen Mitteleuropa, wird aber nach Süden hin, etwa ab Mitteldeutschland, auffallend selten.

description: We present the search for Ultracool dwarfs (UCDs, spectral types later than M7V) performed across the entire Javalambre Photometric Local Universe Survey (J-PLUS) second data release (2 176 deg2) following a VO methodology. We also explore the ability to reproduce this search with a purely machine learning (ML)-based methodology that relies solely on J-PLUS photometry. We followed three different approaches based on parallaxes, proper motions, and colours, respectively, using the VOSA tool to estimate the effective temperatures. For the ML methodology, we built a two-step method based on principal component analysis and support vector machine algorithms. We identified a total of 7 827 new candidate UCDs, which represents an increase of about 135% in the number of UCDs reported in the sky coverage of the J-PLUS second data release. With the ML approach, we obtained a recall score of 92% and 91% in the 20×20 deg2 regions used for testing and blind testing, respectively. We consolidated the proposed search methodology for UCDs, which will be used in deeper and larger upcoming surveys such as J-PAS and Euclid. We concluded that the ML methodology is more efficient in the sense that it allows for a larger number of true negatives to be discarded prior to analysis with VOSA, although it is more photometrically restrictive.

description: This MDP examines the means by which a connection can be formed between virtual spaces and reality through architecture. It investigates the effects mobile technology has on spatial design, and envisages how the public spaces of cultural centre in Calgary could be infused with situated technologies. Traditional typologies of cultural , commercial and community space are confronted with spatial transformations caused by continuous connectivity to virtual communities and networks of information. Using contemporary notions of digital interactivity, a framework is generated to deal with ideas of architecture as an interface to virtual space. This framework discusses how the utilization of Ubiquitous Computing through interactive surfaces, bits & atoms, and ambient media can enhance the experiential qualities of the architecture, without technology becoming invasive or distracting from the purpose of the architecture.

description: We investigate the transverse quark spin densities of the nucleon with the lowest moment within the framework of the SU(3) chiral quark-soliton model, emphasizing the strange quark spin density. Based on previous results of the vector and tensor form factors, we are able to determine the impact-parameter dependent probability densities of transversely polarized quarks in an unpolarized nucleon as well as those of unpolarized quarks in a transversely polarized nucleon. We find that the present numerical results for the transverse spin densities of the up and down quarks are in good agreement with those of the lattice calculation. We predict the transvere spin densities of the strange quark. It turns out that the polarized strange quark is noticeably distorted in an unpolarized proton.

description: DOM Clobbering is a type of code-less injection attack where attackers insert a piece of non-script, seemingly benign HTML markup into a webpage and transform it to executable code by exploiting the unforeseen interactions between JavaScript code and the runtime environment. The attack techniques, browser behaviours, and vulnerable code patterns that enable DOM Clobbering has not been studied yet, and in this paper, we undertake one of the first evaluations of the state of DOM Clobbering on the Web platform. Starting with a comprehensive survey of existing literature and dynamic analysis of 19 different mobile and desktop browsers, we systematize DOM Clobbering attacks, uncovering 31.4K distinct markups that use five different techniques to unexpectedly overwrite JavaScript variables in at least one browser. Then, we use our systematization to identify and characterize program instructions that can be overwritten by DOM Clobbering, and use it to present TheThing, an automated system that detects clobberable data flows to security-sensitive instructions. We instantiate TheThing on the top of the Tranco top 5K sites, quantifying the prevalence and impact of DOM Clobbering in the wild. Our evaluation uncovers that DOM Clobbering vulnerabilities are ubiquitous, with a total of 9,467 vulnerable data flows across 491 affected sites, making it possible to mount arbitrary code execution, open redirections, or client-side request forgery attacks also against popular websites such as Fandom, Trello, Vimeo, TripAdvisor, WikiBooks and GitHub, that were not exploitable through the traditional attack vectors. Finally, in this paper, we also evaluate the robustness of the existing countermeasures, such as HTML sanitizers and Content Security Policy, against DOM Clobbering.

description: We study the two photon decay channel of the Standard Model-like component of the CP-even Higgs bosons present in the type II Seesaw Model. The corresponding cross-section is found to be significantly enhanced in parts of the parameter space, due to the (doubly-)charged Higgs bosons' $(H^{\pm \pm})H^\pm$ virtual contributions, while all the other Higgs decay channels remain Standard Model(SM)-like. In other parts of the parameter space $H^{\pm \pm}$ (and $H^{\pm}$) interfere destructively, reducing the two photon branching ratio tremendously below the SM prediction. Such properties allow to account for any excess such as the one reported by ATLAS/CMS at $\approx 125$ GeV if confirmed by future data; if not, for the fact that a SM-like Higgs exclusion in the diphoton channel around 114-115 GeV as reported by ATLAS, does not contradict a SM-like Higgs at LEP(!), and at any rate, for the fact that ATLAS/CMS exclusion limits put stringent lower bounds on the $H^{\pm \pm}$ mass, particularly in the parameter space regions where the direct limits from same-sign leptonic decays of $H^{\pm \pm}$ do not apply.

description: The automatic modeling of as-built building interiors, known as indoor building reconstruction, is gaining increasing attention because of its widespread applications. With the development of sensors to acquire high-quality point clouds, a new modeling scheme called scan-to-BIM (building information modeling) emerged. However, the traditional scan-to-BIM process is time tedious and labor intensive. Most existing automatic indoor building reconstruction solutions can only fit the specific data or lack of detailed model representation. In this thesis, we propose two automatic reconstruction methods from 2D linear primitives and 3D planar primitives respectively, to create 2D floor plans and 3D building models. The approach using 2D primitives is well suited for large-scale point clouds through a decomposition-and-reconstruction strategy. Moreover, it can retrieve semantic information of rooms and doors simultaneously. Another method using 3D primitives can deal with different types of point clouds and retain as much as structural details with respect to protruding structures, complicated ceilings, and fine corners. The experimental results indicate the effectiveness of proposed methods and the robustness against noises and downsampling.

description: This Master's Degree Project examines the condition of the large-scale retail environment and its potential to net positive contribution to the public realm of the city. It challenges the notion of the "big-box" within its current context to provide more than a one-dimensional shopping experience, and become of succinct part of the urban experience. This design exploration, through analysis and synthesis, proposes a recalibration of the existing commercial components in order to create a diverse commercially based community that merges the pedestrian within an auto-centric culture. Through this recalibration of the key components that comprise the existing large­scale shopping environment - parking, scale, access - and those that provide a more human experience of public space - diversity, engagement, activity - a new application of the existing shopping typology is created; one of social and economic intensity.

description: Humanitarian aid-distribution programs help bring physical goods (e.g., food, blankets) to people in need. Traditional paper-based solutions to support aid distribution do not scale to large populations and are hard to secure. Existing digital solutions solve these issues, at the cost of collecting large amount of personal information. Failing to protect aid recipients' privacy can result on harms for them and enables surveillance in the long run. In collaboration with the International Committee of the Red Cross, we build a safe aid-distribution system in this paper. We first systematize the requirements such a system should satisfy and then propose a decentralized solution based on the use of tokens. Our design provides strong scalability and accountability, at the same time, ensures privacy by design. We provide two instantiations of our design, on a smart card and on a smartphone. We formally prove the security and privacy properties of our design, and empirically show that the two instantiations can scale to hundreds of thousands of recipients.

description: The generic feature of non-conformal fields in Poincare patch of de Sitter space is the presence of large IR loop corrections even for massive fields. Moreover, in global de Sitter there are loop IR divergences for the massive fields. Naive analytic continuation from de Sitter to Anti-de-Sitter might lead one to conclude that something similar should happen in the latter space as well. However, we show that there are no large IR effects in the one-loop two-point functions in the Poincare patch of Anti-de-Sitter space even for the zero mass minimally coupled scalar fields. As well there are neither large IR effects nor IR divergences in global Anti-de-Sitter space even for the zero mass.

description: A series of highly luminescent P-acetylenyl functionalized dithieno[3,2-b:2’,3’-d]phospholes were attempted to be synthesized following the previously studied P-phenyl phosphole as a guide. The original synthesis pathway of forming the dithienophosphole scaffold first, then cross-coupling onto the 2,6-positions, then modifying the acetylene to be able to perform click chemistry saw many difficulties. An alternative route was explored where the cross-coupling reaction with a brominated bithiophene was performed first, then a ring closure reaction to form the phosphole was done. Finally, the emissive materials were able to be clicked onto benzyl azide as a proof-of-concept for an organic light-emitting polymer material for the potential application of solid-state lighting.
Strained cationic heterocycles and other novel phosphaalkene-derived species

Publisher: name: University of British Columbia
Year: 2012

description: This thesis outlines the results from three projects undertaken as part of my Ph.D. studies, with Chapter 1 serving as a general introduction and Chapter 5 serving to summarize the thesis. Chapter 2 details a Lewis acid-mediated methodology for preparing phosphaalkenes from silyl phosphines [RP(SiMe₃)₂; R = alkyl, aryl, silyl] and aldehydes or ketones. The scope of this methodology was explored and phosphaalkenes tBuP=CHtBu (1), AdP=CHtBu (2), MesP=CHtBu (3) and MesP=CPh₂ (4) were prepared on preparative scales. For phosphaalkene 1, this reduced its synthesis from 11 weeks to less than one hour. Additionally, AlCl₃ and GaCl₃ adducts of phosphaalkenes 1 and 2 were synthesized and characterized by X-ray crystallography. In Chapter 3, the reactions of phosphaalkenes 1 and 2 with potential cationic initiators are discussed. For both phosphaalkenes, treatment with substoichiometric HOTf affords rare diphosphiranium cations. Mechanistic studies reveal that this process proceeds via phosphenium triflate intermediates. Unexpectedly, treatment with the related MeOTf affords diphosphetanium cations via methylenephosphonium intermediates. Additionally, it was found that the diphosphetanium cation formed from phosphaalkene 1 would react with two additional equivalents of MeOTf to afford an unprecedented dicationic diphosphetanium. Finally, Chapter 4 describes the abnormal reaction of IMes, a N-heterocyclic carbene (NHC), with phosphaalkenes to afford novel 4-phosphino-2-carbenes. Interestingly, DFT calculations of plausible reaction intermediates suggest the reactions proceed via free abnormal NHCs (aNHCs). The phosphino-functionalized NHC (5), derived from the reaction of IMes with MesP=CPh₂, was used to study the coordination properties of this novel class of ligands. Treating carbene 5 with substoichiometric (tht)AuCl (0.5 equiv) affords a biscarbene complex, indicating that AuCl is preferentially coordinated by the carbene functionality. P-coordination of AuCl occurs when carbene 5 is treated with additional equivalents of AuCl, confirming the bifunctional nature of this ligand. Additionally, rhodium and iridium complexes of the type (NHC)M(CO) ₂Cl (M = Rh, Ir) were prepared and CO stretching frequencies of these complexes suggest that carbene 5 has similar donor properties as IMes.

description: Motivated by the recent neutron scattering experiment on Rb2Cu3SnF12 [Nat. Phys. 6, 865 (2010)], we investigate the effect of Dzyaloshinskii-Moriya interactions in a theoretical model for the magnetic structure of this material. Considering the valence bond solid ground state, which has a 12-site unit cell, we develop the bond operator mean-field theory. It is shown that the Dzyaloshinskii-Moriya interactions significantly modify the triplon dispersions around the Gamma point and cause a shift of the spin gap (the minimum triplon gap) position from the K to Gamma point in the first Brilloin zone. The spin gap is also evaluated in exact diagonalization studies on a 24-site cluster. We discuss a magnetic transition induced by the Dzyaloshinskii-Moriya interactions in the bond operator framework. Moreover, the magnetization process under external magnetic fields is studied within the exact diagonalization and strong coupling expansion approaches. We find that the results of all above approaches are consistent with the experimental findings.

description: We report on the results from {\it Suzaku} X-ray observations of the radio complex region called Kookaburra, which includes two adjacent TeV $γ$-ray sources HESS J1418-609 and HESS J1420-607. The {\it Suzaku} observation revealed X-ray diffuse emission around a middle-aged pulsar PSR J1420-6048 and a plausible PWN Rabbit with elongated sizes of $σ_{\rm X}=1^{\prime}.66$ and $σ_{\rm X}=1^{\prime}.49$, respectively. The peaks of the diffuse X-ray emission are located within the $γ$-ray excess maps obtained by H.E.S.S. and the offsets from the $γ$-ray peaks are $2^{\prime}.8$ for PSR J1420-6048 and $4^{\prime}.5$ for Rabbit. The X-ray spectra of the two sources were well reproduced by absorbed power-law models with $Γ=1.7-2.3$. The spectral shapes tend to become softer according to the distance from the X-ray peaks. Assuming the one zone electron emission model as the first order approximation, the ambient magnetic field strengths of HESS J1420-607 and HESS J1418-609 can be estimated as 3 $μ$G, and $2.5 μ$G, respectively. The X-ray spectral and spatial properties strongly support that both TeV sources are pulsar wind nebulae, in which electrons and positrons accelerated at termination shocks of the pulsar winds are losing their energies via the synchrotron radiation and inverse Compton scattering as they are transported outward.

description: Open source components are ubiquitous in companies’ setups, processes, and software. Utilizing these external components as building blocks enables companies to leverage the benefits of open source software, allowing them to focus their efforts on features and faster delivery instead of writing their own components. But by introducing these components into their software stack, companies inherit unique security challenges and attack surfaces: including code from potentially unvetted contributors, as well as the obligation to assess and mitigate the impact of vulnerabilities in external components. In 25 in-depth, semi-structured interviews with software developers, architects, and engineers from industry projects, we investigate their projects’ processes, decisions, and considerations in the context of external open source code. We find that open source components play an important role in many of our participants’ projects, that most projects have some form of company policy or at least best practice for including external code, and that many developers wish for more developer-hours, dedicated teams, or tools to better audit included components. Based on our findings, we discuss implications for company stakeholders and the open source software ecosystem. Overall, we appeal to companies to not treat the open source ecosystem as a free (software) supply chain and instead to contribute towards the health and security of the overall software ecosystem they benefit from and are part of.

description: Satellites are an essential aspect of our modern society and have contributed significantly to the way we live today, most notable through modern telecommunications, global positioning, and Earth observation. In recent years, and especially in the wake of the New Space Era, the number of satellite deployments has seen explosive growth. Despite its critical importance, little academic research has been con- ducted on satellite security and, in particular, on the security of onboard firmware. This lack likely stems from by now outdated assumptions on achieving security by obscurity, effectively preventing meaningful research on satellite firmware. In this paper, we first provide a taxonomy of threats against satellite firmware. We then conduct an experimental security analysis of three real-world satellite firmware images. We base our analysis on a set of real-world attacker models and find several security-critical vulnerabilities in all analyzed firmware images. The results of our experimental security assessment show that modern in-orbit satellites suffer from different software security vulnerabilities and often a lack of proper access protection mechanisms. They also underline the need to overcome prevailing but obsolete assumptions. To substantiate our observations, we also performed a survey of 19 professional satellite developers to obtain a comprehensive picture of the satellite security landscape.

description: The contribution of the R-parity violating minimal supersymmetric Standard model (RPVMSSM) at the one-loop level to the 199Hg atomic electric dipole moment (EDM) through P, CP-odd electron-nucleon (e-N) interaction is calculated. We show that the current experimental data of the 199Hg EDM give tighter constraints on some of the imaginary parts of R-parity violating (RPV) coupling than those currently known. We add also the analysis of the P, CP-odd 4-quark interaction generated by R-parity violating interactions at the one-loop level, and discuss the possibility to constrain them in future experiments.

description: When considering the existing urban syntax and the potentials for the implementation of change on a large scale through a series small interventions; parallels can be drawn to the Barcelona model. "Barcelona began to pull itself around with a seven-year plan in 1980: 140 small projects provided more plazas and better housing ... the central theme was: make the centre more functional and mediate the expansion of the outskirts." The Barcelona visionaries (Mayors: Joan Clos, Narcis Serra and Pasqual Maragall and Architects: Oriol Bohigas and Josep Acebillo) believe the successful development of a decaying city depends on taking a less fragmented approach. The title 'Urban Acupuncture' speaks to a comprehensive approach that seeks to respond to an existing urban condition through a diagnostical analysis which inherently elicits a prescriptive reaction whereby the illegibility and incohesiveness of the civic fabric of the City of Winnipeg is medicated by a series of small architectural interventions. The City of Winnipeg is plagued by a condition referred to in this document as WasteSpace. The term was coined by a Dutch firm, S333, whose work has responded to a similar condition in the Netherlands responding to a contextual climate where a deficiency of greenfield sites has elicited a new paradigm of brownfield reclamation. They have realized the importance of reclaiming wasted space is high. In Winnipeg we have not yet been met with this condition; a seemingly endless supply of greenfield sites has allowed for rampant suburban expansion that has left the core perforated with an immense series of vacant surface area and a high number of vacant buildings.

description: The well-known Giudice-Masiero mechanism explains the presence of a mu term of the order of the gravitino mass, but does not explain why the holomorphic mass term is absent in the superpotential. We discuss anomaly-free discrete symmetries which are both compatible with SU(5) unification of matter and the Giudice-Masiero mechanism, i.e. forbid the mu term in the superpotential while allowing the necessary Kaehler potential term. We find that these are Z_M^R symmetries with the following properties: (i) M is a multiple of four; (ii) the Higgs bilinear H_u H_d transforms trivially; (iii) the superspace coordinate theta has charge M/4 and, accordingly, the superpotential has charge M/2; (iv) dimension five proton decay operators are automatically absent. All Z_M^R symmetries are anomaly-free due to a non-trivial transformation of a Green-Schwarz axion, and, as a consequence, a holomorphic mu term appears at the non-perturbative level. There is a unique symmetry that is consistent with the Weinberg operator while there is a class of Z_M^R symmetries which explain suppressed Dirac neutrino masses.

description: We compare the semiclassical description of NEMS within and beyond the adiabatic approximation. We consider a NEMS model which contains a single phonon (oscillator) mode linearly coupled to an electronic few-level system in contact with external particle reservoirs (leads). Using Feynman-Vernon influence functional theory, we derive a Langevin equation for the oscillator trajectory that is non-perturbative in the system-leads coupling. A stationary electronic current through the system generates nontrivial dynamical behavior of the oscillator, even in the adiabatic regime. The 'backaction' of the oscillator onto the current is studied as well. For the two simplest cases of one and two coupled electronic levels, we discuss the differences between the adiabatic and the non-adiabatic regime of the oscillator dynamics.

description: The Dominion Radio Astrophysical Observatory is interested in investigating the possibility of replacing 408 MHz narrow-band feed antennas with wide-band antennas. Such change would require low-noise amplifiers (LNAs), which would operate over a wider frequency band. This thesis explores the feasibility of using GaAs p-HEMT transistors to implement a wide-band low-noise amplifier for the 400 MHz to 800 MHz frequencies for use in a wide-band antenna array. In order to demonstrate the feasibility, a three-stage cascaded low-noise amplifier was developed and experimentally verified. The GaAs p-HEMT LNA achieves a sub 0.36dB noise figure in the 390MHz to 810MHz frequency region and a beam-equivalent receiver noise temperature of 17.8K to 28.3K within the 390 MHz-to-810MHz frequency region. The LNA demonstrates S21 > 41.1 dB within the 400 MHz-to-800MHz frequency region while consuming 406mW of power. This LNA has P1dB> -32.9 dBm and IIP3 > -22.5 dBm within the frequency region.

description: The use of partnerships to provide affordable rental housing within the Province of Alberta has gained increased momentum due to the Affordable Housing Partnership Initiative (AHPI) grant program. The purpose of this Master's Degree Project is twofold: to examine the public-private partnership as a model for building affordable housing in smaller communities in Southern Alberta and to provide recommendations for a better partnership framework in the City of Airdrie. The MDP document analyses the affordable rental housing market challenges in Airdrie. It documents the efforts of the City of Airdrie, volunteers, and various non-profit agencies working to address affordable housing needs in the community. The document gives an overview of the partnerships and their evolution in addressing affordable rental housing needs, as well as their advantages and disadvantages. A multi-faceted research strategy is utilised to explore public-private partnerships in two smaller municipalities within the AHPI program. A series of key informant interviews were conducted with representatives from the municipalities, non-profits, private companies, and professionals involved in the field of affordable housing. The final result of the research is a set of recommendations to ensure that the public-private partnership model that is used within the AHPI program and the City of Airdrie can be implemented successfully to generate affordable rental housing.

description: Key management is an integral part of using distributed ledger technology (DLT). Previous work has primarily focused on key management for single-user scenarios on Bitcoin. Over the last decade, DLT has evolved to commercial and financial sectors; for example, a new German law allows the trading of a variety of financial securities via DLT. Instead of a single-user paradigm, financial institutions follow a multi-user paradigm. Combining multi-user key management with single-user key management solutions leads to unique challenges with usability and security. We extend current research through a two-stage qualitative interview study with 13 finance professionals. We investigate how the technical reality contrasts with perceptions of key management practices in corporate financial organizations. Our interdisciplinary study shows, among other things, that DLT does not meet real-world requirements in this particular domain. Moreover, it introduces additional challenges in terms of authentication and auditing. Our findings suggest that corporate financial institutions strongly support the adoption of blockchain solutions. However, to comply with regulatory and operational requirements, they face additional usability and security challenges, e.g., authentication and access control. Better mechanisms or novel design approaches are required to cover professional environments. This includes how multiple users can access the same assets and approve joint transactions.

description: Existing photometry for NGC 2264 tied to the Johnson and Morgan (1953) UBV system is reexamined and, in the case of the original observations by Walker (1956), reanalyzed in order to generate a homogeneous data set for cluster stars. Color terms and a Balmer discontinuity effect in Walker's observations were detected and corrected, and the homogenized data were used in a new assessment of the cluster reddening, distance, and age. Average values of E(B-V)=0.075+-0.003 s.e. and Vo-Mv=9.45+-0.03 s.e. (d=777+-12 pc) are obtained, in conjunction with an inferred cluster age of ~5.5x10^6 yr from pre-main-sequence members and the location of the evolved, luminous, O7 V((f)) dwarf S Mon relative to the ZAMS. The cluster main sequence also contains gaps that may have a dynamical origin. The dust responsible for the initial reddening towards NGC 2264 is no more than 465 pc distant, and there are numerous, reddened and unreddened, late-type stars along the line of sight that are difficult to separate from cluster members by standard techniques, except for a small subset of stars on the far side of the cluster embedded in its gas and dust and background B-type ZAMS members of Mon OB2. A compilation of likely NGC 2264 members is presented. Only 3 of the 4 stars recently examined by asteroseismology appear to be likely cluster members. NGC 2264 is also noted to be a double cluster, which has not been mentioned previously in the literature.

description: Τα τελευταία χρόνια, η βιομηχανία παραγωγής οίνου και ζύθου έχει στρέψει το ενδιαφέρον της στη βελτίωση των προϊόντων της, έπειτα και από απαίτηση του καταναλωτικού κοινού για προϊόντα πιο εξελιγμένα και πολύπλοκα γευστικά και αρωματικά. Για την επίτευξη αυτού του σκοπού το ενδιαφέρον της επιστημονικής κοινότητας έχει στραφεί στις ζύμες, οι οποίες αποτελούν ένα από τα κύρια συστατικά του οίνου και του ζύθου. Συγκεκριμένα, οι έρευνες επικεντρώνονται στις μη συμβατικές ζύμες, γνωστές και ως non-Saccharomyces ζύμες, λόγω της ικανότητάς τους να παράγουν πιο καινοτόμα προϊόντα. Στην παρούσα διπλωματική εργασία μελετάται βιβλιογραφικά η επίδραση της non-Saccharomyces ζύμης, Torulaspora delbrueckii. Η μελέτη επικεντρώνεται στα γενικά χαρακτηριστικά του συγκεκριμένου μικροοργανισμού, στη ζυμωτική του ικανότητα σε γλεύκη οίνων και ζύθων, καθώς και στον τρόπο με τον οποίο η T. delbrueckii δρα στις διάφορες παραμέτρους ζύμωσης, σε καθαρή καλλιέργεια ζύμωσης, αλλά και σε συνεργασία με τον συμβατικό ζυμομύκητα, Saccharomyces cerevisiae. Επιπλέον εξετάζεται ο τρόπος με τον οποίο ανταποκρίνεται η ζύμη αυτή σε συνθήκες ωσμωτικού στρες, καθώς και η επίδρασή της στα διάφορα οργανοληπτικά χαρακτηριστικά των οίνων και των ζύθων.

description: We have developed a photon counting detector system for combined neutron and gamma radiography which can determine position, time and intensity of a secondary photon flash created by a high-energy particle or photon within a scintillator screen. The system is based on a micro-channel plate photomultiplier concept utilizing image charge coupling to a position- and time-sensitive read-out anode placed outside the vacuum tube in air, aided by a standard photomultiplier and very fast pulse-height analyzing electronics. Due to the low dead time of all system components it can cope with the high throughput demands of a proposed combined fast neutron and dual discrete energy gamma radiography method (FNDDER). We show tests with different types of delay-line read-out anodes and present a novel pulse-height-to-time converter circuit with its potential to discriminate gamma energies for the projected FNDDER devices for an automated cargo container inspection system (ACCIS).
