Résumé :

ABSTRACTBacterial binuclear iron monooxygenases play numerous physiological roles in oxidative metabolism. Monooxygenases of this type found in actinomycetes also catalyze various useful reactions and have attracted much attention as oxidation biocatalysts. However, difficulties in expressing these multicomponent monooxygenases in heterologous hosts, particularly inEscherichia coli, have hampered the development of engineered oxidation biocatalysts. Here, we describe a strategy to functionally express the mycobacterial binuclear iron monooxygenase MimABCD inEscherichia coli. Sodium dodecyl sulfate-polyacrylamide gel electrophoretic analysis of themimABCDgene expression inE. colirevealed that the oxygenase components MimA and MimC were insoluble. Furthermore, although the reductase MimB was expressed at a low level in the soluble fraction ofE. colicells, a band corresponding to the coupling protein MimD was not evident. This situation rendered the transformedE. colicells inactive. We found that the following factors are important for functional expression of MimABCD inE. coli: coexpression of the specific chaperonin MimG, which caused MimA and MimC to be soluble inE. colicells, and the optimization of themimDnucleotide sequence, which led to efficient expression of this gene product. These two remedies enabled this multicomponent monooxygenase to be actively expressed inE. coli. The strategy described here should be generally applicable to theE. coliexpression of other actinomycetous binuclear iron monooxygenases and related enzymes and will accelerate the development of engineered oxidation biocatalysts for industrial processes.

Résumé :

This study aimed to prepare a molecularly imprinted monolithic extraction column (MIMC) inside a micropipette tip by situ polymerization with roxithromycin as the dummy template. The polymers possessed excellent adsorption capacity and class-specificity to multiple macrolide drugs. MIMC was directly connected to a syringe for template removal and for the optimization of extraction conditions without any other post-treatment of polymers. A liquid chromatography-tandem mass spectrometric method was developed for the selective microextraction and determination of macrolide antibiotics in animal muscles based on MIMC. High recoveries of 76.1–92.8% for six macrolides were obtained with relative standard deviations less than 10.4%. MIMC exhibited better retention ability and durability when compared with the traditional C18 and HLB cartridges. The proposed method shows a great potential for the analysis of macrolide drugs at the trace level in animal foodstuffs.

Résumé :

ZusammenfassungIntermediate Care (IMC)-Stationen erfüllen die komplexen Behandlungserfordernisse von Patienten mit speziellen Erkrankungen und/oder einem hohen Pflegebedarf und können dazu beitragen, die Belegung von Intensivbetten effizient/er zu gestalten. Trotz Ausgliederung der Pflegepersonalkosten von dem Diagnosis-Related-Groups (DRG; Deutsch: diagnosebezogene Fallgruppen)-Vergütungssystem können längere Phasen unterdurchschnittlicher Monatserlöse durch ausbleibende Abrechnung komplexer DRGs und/oder Fehlbelegung/Sperrung von IMC-Betten zu einem Fixkosten-Refinanzierungsproblem führen; das stellt die Frage nach der Rentabilität einer IMC-Einheit erneut in den Vordergrund. Somit ist Ziel dieser Arbeit gewesen, die Rentabilität einer gastroenterologischen IMC, als Teil einer interdisziplinären Medizinischen IMC (MIMC) am Universitätsklinikum Essen, für den Zeitraum 01.01.2014–31.12.2016 zu bewerten. Retrospektiv wurden 1015 Fälle der Station MIMC der Klinik für Gastroenterologie und Hepatologie (Med.G./MIMC; 12 IMC-Betten) hinsichtlich Verweildauer (VWD), Aufnahme-/Hauptdiagnose, erbrachten Prozeduren sowie Nebendiagnosen, Erlös, Alter und Geschlecht untersucht (medianes Patientenalter 57 Jahre; ♂ 61%, ♀ 39%). Insgesamt kommen 85% der DRG-Erlöse durch Behandlungsfälle innerhalb der Top-20-Basis-DRGs zustande; diese verdeutlichen den hepatologischen Schwerpunkt der Med.G./MIMC. Der Case-Mix (CM) beträgt im monatlichen Durchschnitt 65; der CM-Index (CMI), der (analog zum CM) eine erhebliche jahreszeitliche Schwankung aufweist, beträgt im monatlichen Durchschnitt 10,891 (2014–2016). Die durchschnittliche VWD auf der Med.G./MIMC liegt mit 12,3 Tagen deutlich über der Durchschnitt-VWD in deutschen Krankenhäusern (7,2 Tage). In der konkreten wirtschaftlichen Beurteilung der Med.G./MIMC ergibt sich, dass die zugeordneten stationären Erlöse von 2,90 Mio. € auf 3,72 Mio. € ansteigen. Damit ist eine positive Entwicklung der Primärerlöse von 2,98 Mio. € (2014) über 3,56 Mio. € (2015) auf 3,81 Mio. € (2016) bei weitestgehend konstantem Aufwand im Bereich der Primärkosten und der bezogenen Sekundärleistungen zu verzeichnen. Aus der Erfahrung ist dies – unter Berücksichtigung der potenziellen interdisziplinären Synergieeffekte – als außerordentlich gute wirtschaftliche Situation zu bezeichnen.

Résumé :

For Arithmetization-Oriented ciphers and hash functions Gröbner basis attacks are generally considered as the most competitive attack vector. Unfortunately, the complexity of Gröbner basis algorithms is only understood for special cases, and it is needless to say that these cases do not apply to most cryptographic polynomial systems. Therefore, cryptographers have to resort to experiments, extrapolations and hypotheses to assess the security of their designs. One established measure to quantify the complexity of linear algebra-based Gröbner basis algorithms is the so-called solving degree. Caminata & Gorla revealed that under a certain genericity condition on a polynomial system the solving degree is always upper bounded by the Castelnuovo-Mumford regularity and henceforth by the Macaulay bound, which only takes the degrees and number of variables of the input polynomials into account. In this paper we extend their framework to iterated polynomial systems, the standard polynomial model for symmetric ciphers and hash functions. In particular, we prove solving degree bounds for various attacks on MiMC, Feistel-MiMC, Feistel-MiMC-Hash, Hades and GMiMC. Our bounds fall in line with the hypothesized complexity of Gröbner basis attacks on these designs, and to the best of our knowledge this is the first time that a mathematical proof for these complexities is provided. Moreover, by studying polynomials with degree falls we can prove lower bounds on the Castelnuovo-Mumford regularity for attacks on MiMC, Feistel-MiMC and Feistel-MiMCHash provided that only a few solutions of the corresponding iterated polynomial system originate from the base field. Hence, regularity-based solving degree estimations can never surpass a certain threshold, a desirable property for cryptographic polynomial systems.

Résumé :

During fieldwork in Ladakh in July–August 2018, three authors from Asian studies, anthropology, and religious studies backgrounds researched “multiple Buddhisms” in Ladakh, India. Two case studies are presented: a Buddhist monastery festival by the Drikung Kagyü Tibetan Buddhist sect, and a Theravada monastic complex, called Mahabodhi International Meditation Center (MIMC). Through the transnational contexts of both of these case studies, we argue that Buddhist leaders adapt their teachings to appeal to specific audiences with the underlying goal of preserving the tradition. The Buddhist monastery festival engages with both the scientific and the magical or mystical elements of Buddhism for two very different European audiences. At MIMC, a secular spirituality mixes with Buddhism for international tourists on a meditation retreat. Finally, at MIMC, Thai Buddhist monks learn how to fight the decline of Buddhism through missionizing Theravada Buddhism in this land dominated by Mahayana and Vajrayana Buddhism. Paying attention to this multiplicity—to “multiple Buddhisms”—we argue, makes space for the complicated, ambiguous, and at times contradictory manner in which Buddhism is positioned in regards to secularism and secularity.

Résumé :

HighlightsMine water irrigation can promote the plant height growth of winter wheat, but inhibit the growth of leaf area.High salinity mine water irrigation will inhibit the growth and development of winter wheat and reduce the yield.Mixed irrigation of mine water and clean water (the ratio is 1:1) is beneficial to the growth of winter wheat.Short-term mine water irrigation will not cause soil salinization.Abstract. There is a serious shortage of irrigation water in the overlapped areas of crop and mineral production in North China. The key to solve the problem is to utilize mine water safely and efficiently. The effects of mine water irrigation (MI), mixed mine water and clean water irrigation (MIMC), rotational mine water and clean water irrigation, irrigated with mine water first, then clean water (RIMC) and clean water irrigation (CK) on winter wheat growth and soil salinity were studied through two years of field trials (2012 to 2014). The results showed that different models of mine water irrigation had no difference in plant height, but had obvious inhibitory effect on leaf area of wheat. Compared with CK, MI increased plant height by 1.0% to 3.4%, and leaf area was 69.5% to 81.9% of that of CK. Compared with CK, the yield of MIMC was increased by 2.6% to 6.67%, and the yield of RIMC and MI was decreased by 3.4% to 21.1% and 10.4% to 11.2%, respectively. The MI with high salinity could inhibit the growth and development of winter wheat, and reduce the yield and quality, while the yield of MIMC was higher than that of CK, and could improve the quality of winter wheat. Long-term irrigation of using mine water with high salinity will increase the risk of soil salinization, but MIMC can improve soil fertility. Keywords: Growth, Irrigation, Mine water, Soil salinity, Winter wheat.

Résumé :

The utilization of wireless mesh networks (WMNs) has greatly increased, and the multi-interface multichannel (MIMC) technic has been widely used for the backbone network. Unfortunately, the ad hoc on-demand distance vector (AODV) routing protocol defined in the IEEE 802.11s standard was designed for WMNs using the single-interface single-channel technic. So, we define a problem that happens when the legacy AODV is used in MIMC WMNs and propose an interface assignment-based AODV (IA-AODV) in order to resolve that problem. IA-AODV, which is based on multitarget path request, consists of the PREQ prediction scheme, the PREQ loss recovery scheme, and the PREQ sender assignment scheme. A detailed operation according to various network conditions and services is introduced, and the routing efficiency and network reliability of a network using IA-AODV are analyzed over the presented system model. Finally, after a real-world test-bed for MIMC WMNs using the IA-AODV routing protocol is implemented, the various indicators of the network are evaluated through experiments. When the proposed routing protocol is compared with the existing AODV routing protocol, it performs the path update using only 14.33% of the management frames, completely removes the routing malfunction, and reduces the UDP packet loss ratio by 0.0012%.

Résumé :

e17015 Background: PSMA PET has been widely adopted in restaging of prostate cancer at biochemical recurrence. We assess the clinical utility of quantitative parameters on 18F-DCFPyL PET/CT at biochemical recurrence and their association with the subsequent biochemical progression free survival (bPFS). Methods: This is a retrospective image analysis and longitudinal follow up of a prospective study evaluating 18F-DCFPyL PET in prostate cancer patients with biochemical recurrence after primary definitive treatment at Stanford Hospital. The 18F-DCFPyL PET images were quantitatively analyzed automatically by the aPROMISE application, a semi-automated analysis and structured reporting of PSMA PET/CT. aPROMISE uses deep learning to segment detailed anatomical information from the CT images and uses this information in combination with the PET image to detect and quantify candidates for prostate cancer lesions. The reader works in tandem with the software to vet the final list of lesions, from which the quantitative assessments and final report is created automatically. Based on the Prostate Cancer Molecular Imaging Standardized Evaluation (PROMISE) criteria. SUVmean, PSMA positive total tumor volume (PSMAttv) and aPSMA scores, a quantitative score for tumor burden measuring the interaction of tumor volume and uptake stratified by local tumors (aPSMA-miT), regional lymph nodes (aPSMA-miN) and distant metastases (aPSMA-miMa for extrapelvic metastases, miMb for bone metastases and miMc for other organ metastases) were obtained based on the miTNM classification. The association of these quantitative parameters with the subsequent bPFS was evaluated. Results: 134 patients (age 70.1 ± 7.6, range 51 -91 years; PSA 13.9 ± 98.5, range 0.12 – 1126 ng/mL) were included in the quantitative image analysis. aPROMISE detected nodal and/or bone metastases in 94 of 134 patients (70%) and only 12 of 134 patients (9%) had visceral disease. With median follow up of 37 months, 66 of 134 patients (49%) have progressed again biochemically after treatment. The bPSF was 25.8 ± 15.1 months. Quantitative analysis of 18F-DCFPyL PET found that the subsequent bPFS is significantly associated with aPSMA-miMb ( P < 0.001), PSMAttv ( P < 0.001), aPSMA-miN ( P < 0.01), aPSMA-miMa ( P < 0.05) but not with SUVmean or aPSMA-miMc. Conclusions: Total and anatomically contextualized quantitative image analysis of 18F-DCFPyL PET/CT at biochemical recurrence may be useful in predicting the subsequent bPFS. Studies in larger patient cohort is necessary to validate these findings. Given many patients were treated based on lesions found on 18F-DCFPyL PET/CT, clinical implication of this findings remains to be elucidated.

Résumé :

Real-time video transmission demands tremendous bandwidth, throughput and strict delay. For transmitting real-time video in the multi-interface multi-channel Ad hoc, firstly, we applied multi-interface multi-channel extension methods to the AOMDV (Ad-hoc On-demand Multipath Distance Vector) routing protocol, and improved extant channel switching algorithm, called MIMC-AOMDV (Multi-Interface Multi-Channel AOMDV) routing protocol. Secondly, we proposed video streaming delay QoS(Quality of Service) constraint and link-quality metrics, which used the multi interface queue’s total used length to get QMMIMC-AOMDV (Quality metric MIMC -AOMDV) routing protocol. The simulations show that the proposed QMMIMC-AOMDV can reduce the frame delay effectively and raise frame decodable rate and peak signal to noise ratio (PSNR), it is more suitable for real-time video streams.

Résumé :

Ces dernières années, de nouvelles primitives de cryptographie symétrique ont été proposées pour être utilisées dans des protocoles avancés comme le calcul multi-partite, en combinaison avec un chiffrement homomorphe ou encore dans divers systèmes de preuve à apport nul de connaissance. De tels protocoles s’inscrivent dans un contexte marqué par le développement du Cloud et des technologies de type Blockchain et doivent ainsi répondre à une préoccupation croissante des utilisateurs en matière de sécurité. Ces protocoles ont mis en avant le besoin de minimiser le nombre de multiplications effectuées par la primitive dans des corps finis de grande taille. Les algorithmes symétriques classiques sont alors inappropriés dans ce contexte et les nouveaux protocoles cryptographiques doivent être combinés avec des primitives symétriques (chiffrement ou fonction de hachage) ayant des propriétés particulières. Alors que le nombre de conceptions définies sur de grands corps dites "orientées arithmétisation" augmente de façon considérable, très peu de travaux d’analyse de sécurité ont été proposés jusqu'ici. L’objectif de ce manuscrit est donc en premier lieu de contribuer à combler ce manque pour mieux comprendre les spécificités de ces nouveaux outils. Nous proposons également une nouvelle vision pour concevoir de telles primitives, couvrant ainsi les deux sous-domaines de la cryptologie que sont la cryptographie et la cryptanalyse
In recent years, new symmetric cryptographic primitives have been proposed for advanced protocols, like multi-party computation, in combination with a fully homomorphic encryption or in various systems of zero-knowledge proofs. Such protocols are parts of a context marked by the development of cloud and blockchain technologies, and must therefore respond to the growing security concerns of users. These protocols have put forward the need to minimize the number of multiplications performed by the primitive in large finite fields. Classical symmetric algorithms are then inappropriate in this context and the new cryptographic protocols must be combined with symmetric primitives (encryption or hash function) with particular properties. While the number of designs defined over large fields, called "arithmetisation-oriented", is increasing significantly, few cryptanalysis works have been proposed. The first aim of this manuscript is then to contribute to fill this gap, and hence to better understand the specificities of these new objects. We also propose a new vision to design such primitives, covering both aspects of cryptology, the cryptography and the cryptanalysis

Résumé :

Parmi les nombreux agents thérapeutiques utilisés en oncologie, le paclitaxel (Taxol®) est sans doute celui qui a suscité le plus d'intérêt. Il est utilisé en clinique pour le traitement des cancers de l'ovaire, du sein et des poumons. Il agit comme poison du fuseau mitotique en favorisant l'assemblage de la tubuline en microtubules et en stabilisant le polymère formé. Initialement extrait de l'if du Pacifique (Taxus Brevifolia) puis obtenu par hémisynthèse à partir de la 10-déacétylbaccatine III, il est aujourd'hui produit par un procédé biotechnologique de fermentation de cellules végétales. Le paclitaxel possède une structure chimique complexe basée sur un squelette tétracyclique taxane. Une approche visant à remplacer ce squelette taxane par une structure chimique plus simple a été entreprise afin d'identifier des mimes du paclitaxel. L'identification d'un fragment chimique (fragment based drug design) dérivé de la proline par une étude de modélisation moléculaire a permis de développer de nouvelles séries de mimes du paclitaxel. Parallèlement, le remplacement du squelette taxane par une matrice peptidique cyclique utilisant des dérivés de la proline a été réalisé. Les études de modélisation moléculaire, la synthèse des mimes du paclitaxel et leur évaluation biologique seront présentées
Among the many therapeutic agents used in oncology, paclitaxel (Taxol®) is probably the one that generated the most interest. It is used clinically for the treatment of ovarian, breast and lung cancers and acts as a mitotic spindle poison by promoting the assembly of tubulin into microtubules and stabilizing the polymer formed. Initially extracted from the Pacific yew (Taxus Brevifolia) and obtained by semi-synthesis from 10-deacetylbaccatin III, it is now produced by a biotechnological process of cell plant fermentation. Paclitaxel has a complex chemical structure based on a tetracyclic taxane skeleton. A process to replace the taxane skeleton with a simpler chemical structure was undertaken to identify paclitaxel mimics. The identification of a chemical fragment (fragment based drug design) derived from proline by a molecular modeling study has led to the design of a new series of paclitaxel mimics. Meanwhile, replacing the taxane skeleton by a cyclic peptide scaffold using proline derivatives was performed. Molecular modeling studies, synthesis of paclitaxel mimics and biological evaluation will be presented

Résumé :

Les systèmes de communications MIMO utilisent des réseaux de capteurs qui peuvent s’étendre à de grandes dimensions (MIMO massifs) et qui sont pressentis comme solution potentielle pour les futurs standards de communications à très hauts débits. Un des problème majeur de ces systèmes est le fort niveau d’interférences dû au grand nombre d’émetteurs simultanés. Dans un tel contexte, les solutions ’classiques’ de conception de pilotes ’orthogonaux’ sont extrêmement coûteuses en débit utile permettant ainsi aux solutions d’identification de canal dites ’aveugles’ou ’semi-aveugles’ de revenir au-devant de la scène comme solutions intéressantes d’identification ou de déconvolution de ces canaux MIMO. Dans cette thèse, nous avons commencé par une analyse comparative des performances, en nous basant sur les CRB, afin de mesurer la réduction potentielle de la taille des séquences pilotes et ce en employant les méthodes dites semi-aveugles. Les résultats d’analyse montrent que nous pouvons réduire jusqu’à 95% des pilotes sans affecter les performances d’estimation du canal. Nous avons par la suite proposé de nouvelles méthodes d’estimation semi-aveugle du canal, permettant d’approcher la CRB. Nous avons proposé un estimateur semi-aveugle, LS-DF qui permet un bon compromis performance / complexité numérique. Un autre estimateur semi-aveugle de type sous-espace a aussi été proposé ainsi qu’un algorithme basé sur l’approche EM pour lequel trois versions à coût réduit ont été étudiées. Dans le cas d’un canal spéculaire, nous avons proposé un algorithme d’estimation paramétrique se basant sur l’estimation des temps d’arrivés combinée avec la technique DF
MIMO systems use sensor arrays that can be of large-scale (massive MIMO) and are seen as a potential candidate for future digital communications standards at very high throughput. A major problem of these systems is the high level of interference due to the large number of simultaneous transmitters. In such a context, ’conventional’ orthogonal pilot design solutions are expensive in terms of throughput, thus allowing for the so-called ’blind’ or ’semi-blind’ channel identification solutions to come back to the forefront as interesting solutions for identifying or deconvolving these MIMO channels. In this thesis, we started with a comparative performance analysis, based on CRB, to quantify the potential size reduction of the pilot sequences when using semi-blind methods that jointly exploit the pilots and data. Our analysis shows that, up to 95% of the pilot samples can be suppressed without affecting the channel estimation performance when such semi-blind solutions are considered. After that, we proposed new methods for semi-blind channel estimation, that allow to approach the CRB. At first, we have proposed a SB estimator, LS-DF which allows a good compromise between performance and numerical complexity. Other SB estimators have also been introduced based on the subspace technique and on the ML approach, respectively. The latter is optimized via an EM algorithm for which three reduced cost versions are proposed. In the case of a specular channel model, we considered a parametric estimation method based on times of arrival estimation combined with the DF technique

Résumé :

Ao longo deste trabalho, problemas relacionados aos sistemas de comunicação equipados com múltiplas antenas no transmissor e receptor (MIMO - Multiple- Input Multiple-Output) são analisados sob o ponto de vista de detecção clássica, da otimização não-linear, bem como da pré-codificação linear, desde MIMO convencional (algumas antenas no Tx e Rx) até sistemas MIMO de larga-escala (massivo). Inicialmente, a eficiência de detecção de vários detectores MIMO foi analisada sob a prerrogativa de canais altamente correlacionados, situação em que sistemas MIMO apresentam elevada perda de desempenho, além de, em alguns casos, uma crescente complexidade. Diante deste cenário, foi estudado especificamente o comportamento em termos do compromisso complexidade x taxa de erro de bits (BER - Bit Error Rate), para diferentes técnicas de detecção, como o cancelamento de interferências sucessivo (SIC), redução treliça (LR), bem como a combinação de cada uma destas às técnicas lineares de detecção. Nessa análise, também foram considerados diferentes estruturas de antenas uniformes com arranjos geométricos lineares (ULA - uniform linear array) e de arranjo planar (UPA - uniform planar array) em ambos transmissor e receptor. Além disso, também foram considerados diferentes número de antenas e ordem de modulação. Em seguida, o problema de detecção MIMO foi estudado sob uma perspectiva de otimização não-linear, visando especificamente alcançar o desempenho ótimo. Foi analisada a solução de detecção com relaxação semi-definida (SDR - semi- definite relaxation). O detector SDR-MIMO é uma abordagem eficiente capaz de atingir o desempenho muito próximo ao ótimo, especialmente para baixas e médias ordens de modulação. Concentramos nossos esforços no desenvolvimento de uma aproximação computacionalmente eficiente para o algoritmo de detecção de máxima verossimilhança (ML - Maximum Likelihood) MIMO baseado na programação semi-definida (SDP - Semidefinite Programming) para as constelações M-QAM. Finalmente, estuda-se um problema de alocação de potência com o objetivo de maximizar a capacidade de um canal de broadcasting MIMO massivo em uma única célula equipada com pré-codificação forçagem à zero (ZFBF - zero-forcing beamforming) e inversão de canal regularizado (RCI - regularized channel inversion) na estação rádio base (BS). Nosso objetivo é investigar esse problema considerando um sistema massivo no limite, ou seja, quando o número de usuários, K, e antenas na BS, M, tendem ao infinito porém com uma razão constante, β = K M . Primeiramente deriva-se a relação sinal-interferência mais ruído (SINR) para ambos os pré-codificadores escolhidos. Em seguida, investiga-se um esquemas de alocação de potência ótimo que maximiza a soma das capacidades por antena sob uma restrição de potência máxima disponível, conclui-se que o problema é convexo e que a alocação de potência ótima segue a estratégia de watter-filling (WF). Também estudou-se o problema relacionado à alocação de potência em um grupo finito de usuários separados em grupos e determinou-se o impacto desse esquema na capacidade total do sistema.
Throughout this work, problems related to communication systems equipped with multiple antennas in the transmitter and receiver (MIMO - Multiple-Input Multiple-Output) are analyzed from the point of view of classical detection, nonlinear optimization, as well as linear pre-coding, from conventional MIMO (some Tx and Rx antennas) to large-scale (massive) MIMO systems. Initially, the detection efficiency of several MIMO detectors were analyzed under the prerogative of highly correlated channels, in which situation, MIMO systems present a high loss of performance, and, in some cases, an increasing complexity. Considering this scenario, we have specifically studied the behavior in terms of compromise complexity x bit error rate (BER), for different detection techniques, such as the successive interference cancellation (SIC), lattice reduction (LR), as well as the combination of each of these with linear detection techniques. In this analysis, different uniform antenna structures with uniform linear array (ULA) and planar array array (UPA) were also considered in both transmitter and receiver side. In addition, different number of antennas and order of modulation were also considered. Next, the MIMO detection problem was studied from a nonlinear optimization perspective, specifically aiming to achieve optimum performance. The detection solution with semi-defined relaxation (SDR - it semidefinite relaxation) were analyzed. The SDR-MIMO detector is an efficient approach capable of achieving near-optimal performance, especially for low and medium modulation orders. We focused our efforts on developing a computationally efficient approach for the maximum likelihood (ML) MIMO detection algorithm based on semi-definite programming (SDP) for M-QAM constellations. Finally, we study an optimal power allocation problem aiming to maximizes the sum-rate capacity of a single cell massive MIMO broadcast channel equipped with zero-forcing beamforming (ZFBF) and regularized channel inversion (RCI) precoding at the base station (BS). Our purpose is to investigate this problem in the large-scale system limit, i.e, when the number of users, K, and antennas at the BS, M, tend to infinity with a ratio β = K/M being held constant. We first derive the signal to interference plus noise (SINR) ratio for both chosen precoders. Then we investigate optimal power allocation schemes that maximize the sum-rate per antenna under an average power constraint and we show that the problem is convex and the power allocation follows the well-known Water-Filling strategy. We also studied a problem related to an optimal power allocation at a finite group of clustered users and determine the impact of this scheme in the ergodic sum-rate capacity.

Résumé :

Abstract The multiple-input multiple-output (MIMO) technique combined with an orthogonal frequency division multiplexing (MIMO--OFDM) has been introduced as a promising approach for the ever increasing capacity and quality of service (QoS) requirements for wireless communication systems. An efficient radio spectrum utilization expects a flexible transceiver solution, which has been the reason for the development of the software defined radio (SDR) technologies which in their turn are expected to enable the creation of cognitive radios. As a result, any radio solution could be invoked on demand on any platform. In this thesis work, we have studied detector algorithms and programmable processor architectures in order to find practical solutions for the future wireless systems. A programmable receiver can reduce the energy dissipation of the receiver by changing the detection algorithm based on the current channel realizations. To provide a realistic aspect to the implementations in different channel realizations, we present a wide state-of-the-art detector comparison. In addition, we present an extensive number arithmetic and word length study in order to evaluate realistic hardware complexity and energy dissipations of the implementations. The study includes a comprehensive design chain from the algorithm development to the actual processor design and finally programming software for the platforms. We evaluate single and multi-core processor implementations by comparing the achieved results to the Long Term Evolution (LTE) performance requirements. We implement detectors on digital signal processors (DSPs), graphics processing unit (GPU) and transport triggered architecture (TTA). The implementation results are compared in throughput, silicon area and energy efficiency. Finally, we discuss the advantages and disadvantages of the architectures and the implementation effort

Ohjelmoitavalla vastaanottimella voidaan vähentää vastaanottimen energiankulutusta vaihtamalla ilmaisinalgoritmeja vallitsevan kanavatilan mukaan. Työssä esitellään laaja, viimeisintä tutkimusta edustava ilmaisinalgoritmivertailu, joka antaa realistisen näkökannan toteutuksiin erilaisissa kanavatiloissa. Lisäksi työssä esitellään numeroaritmetiikka- ja sananpituustutkimus, jonka tarkoituksena on arvioida toteutusten realistista kovokompleksisuutta sekä energiankulutusta.

Résumé :

In wireless systems, radio signals are corrupted due to fading, interference and noise. In order to handle the effects of fading and interference, modern systems employ various techniques including multi-antenna transceivers. Initially, multi-antenna systems were proposed only for point-point communication. More recently, multi-antenna transceivers have been proposed for multiuser (MU) wireless systems. There are various topologies in which multi-antenna transceivers can be used in a multiuser wireless environment. Among them, macrodiversity is an important concept driven by many scenarios, including base station cooperation, coordinated multipoint (CoMP) transmission and network multiple input multiple output (MIMO). A communication system where antenna elements at both source and receiver are widely (geographically) separated is described as a macrodiversity communication system. For these macrodiversity systems, every link may have a different average signal to noise ratio (SNR) since the sources and the receive antennas are all in different locations. This variation in average SNR across the links makes the performance analysis of such systems more complex. For this reason, most of the results currently available are based on simulation. However, the value of analytical results can be immense for efficient computation and optimized operation. Therefore, in this thesis we present a comprehensive, and rigorous analytical investigation of various aspects of multiuser macrodiversity MIMO systems. Two main aspects of macrodiversity MIMO systems are considered: the multiple access channel (MAC) and uplink user scheduling. In the earlier chapters of the thesis, we investigate the performance of uplink transmission employing multi-antenna transmitters and receivers. We analyze the signal-to-interference plus noise ratio (SINR) performance, symbol error rate (SER) and ergodic sum capacity etc. In a later chapter, we consider multiuser scheduling issues in macrodiversity multiuser MIMO systems. The primary emphasis is on the MIMO-MAC where we present some systematic performance metrics and approaches to multiuser scheduling which only require the long term channel state information (CSI). These methods provide a double advantage over scheduling using instantaneous CSI. First, the computational burden is lower and secondly, the delay between obtaining and using channel estimation is reduced.

Résumé :

Abstract The manifold microchannel (MMC) heat sink system has been widely used in high-heat-flux chip thermal management due to its high surface-to-volume ratio. Two-phase, three-dimensional numerical methods for subcooled flow boiling have been developed using a self-programming solver based on OpenFOAM. Four different types of manifold arrangements (Z-type, C-type, H-type and U-type) have been investigated at a fixed operational condition. The numerical results evaluate the effects of flow maldistribution caused by different manifold configurations. Before simulating the two-phase boiling flow in MIMC metamodels, single-phase liquid flow fields are performed at first to compare the flow maldistribution in microchannels. It can be concluded from the flow patterns that H-type and U-type manifolds provide a more even and a lower microchannel void fraction, which is conducive to improving the temperature uniformity and decreasing the effective thermal resistance. The simulation results also show that the wall temperature difference of H-type (0.471 K) is only about 10% of the Z-type (4.683 K). In addition, the U-type manifold configuration show the lowest average pressure drop at the inlet and outlet of the MIMC metamodel domain. However, H-type manifold also shows an impressive 59.9% decrease in pressure loss. Results indicate that both the H-type and the U-type manifolds for flow boiling in microchannels are recommended due to their better heat transfer performance and lower pressure drop when compared with Z-type and C-type.

Résumé :

Australia's and China's resources (e.g. Olympic Dam Cu-U-Au-Ag and Bayan Obo REE deposits) highlight how discovery and mining of iron oxide copper-gold (IOCG), iron oxide±apatite (IOA) and affiliated primary critical metal deposits in metasomatic iron and alkali-calcic (MIAC) mineral systems can secure a long-term supply of critical metals for Canada and its partners. In Canada, MIAC systems comprise a wide range of undeveloped primary critical metal deposits (e.g. NWT NICO Au-Co-Bi-Cu and Québec HREE-rich Josette deposits). Underexplored settings are parts of metallogenic belts that extend into Australia and the USA. Some settings, such as the Camsell River district explored by the Dene First Nations in the NWT, have infrastructures and 100s of km of historic drill cores. Yet vocabularies for mapping MIAC systems are scanty. Ability to identify metasomatic vectors to ore is fledging. Deposit models based on host rock types, structural controls or metal associations underpin the identification of MIAC-affinities, assessment of systems' full mineral potential and development of robust mineral exploration strategies. This workshop presentation reviews public geoscience research and tools developed by the Targeted Geoscience Initiative to establish the MIAC frameworks of prospective Canadian settings and global mining districts and help de-risk exploration for IOCG, IOA and affiliated primary critical metal deposits. The knowledge also supports fundamental research, environmental baseline assessment and societal decisions. It fulfills objectives of the Canadian Mineral and Metal Plan and the Critical Mineral Mapping Initiative among others. The GSC-led MIAC research team comprises members of the academic, private and public sectors from Canada, Australia, Europe, USA, China and Dene First Nations. The team's novel alteration mapping protocols, geological, mineralogical, geochemical and geophysical framework tools, and holistic mineral systems and petrophysics models mitigate and solve some of the exploration and geosciences challenges posed by the intricacies of MIAC systems. The group pioneers the use of discriminant alteration diagrams and barcodes, the assembly of a vocab for mapping and core logging, and the provision of field short courses, atlas, photo collections and system-scale field, geochemical, rock physical properties and geophysical datasets are in progress to synthesize shared signatures of Canadian settings and global MIAC mining districts. Research on a metamorphosed MIAC system and metamorphic phase equilibria modelling of alteration facies will provide a foundation for framework mapping and exploration of high-grade metamorphic terranes where surface and near surface resources are still to be discovered and mined as are those of non-metamorphosed MIAC systems.

Résumé :

The objective of this project was to start the process of making the MIVC technique simple and cost effective for use in the field by reducing both the size of the required sensors and instrumentation and the calibration requirements. Three steps were taken to meet this objective: (1) design and build a small, lightweight magnetic circuit that can be handled by a single technician, (2) reduce the number and size of the instruments used to perform the MIVC measurements, and (3) investigate the variability of the MIVC calibration curves among different pipe grades and the feasibility of establishing a universal calibration curve or family of curves.
