Abstract:
The development of technology today has emerged the latest technology in three-dimensional (3D) printer machines. Problems faced by 3D printers include the position of the printer bed that is not horizontal. The position of the printer bed that is not horizontal will cause the 3D print to be skewed. To overcome the problem of tilting the bed of a 3D printer, the auto-level system is needed, which is a system that can correct the position of the base so that it becomes horizontal. In this study, an auto-leveling system was designed and made for four 3D printing base support positions. The drive for the printing press uses a stepper motor with a worm gear transmission. The controller uses an Arduino board and tested various position sensors to determine the slope of the base. The sensor tested is a 3D touch probe sensor. From the test results, the 3D touch probe sensor has a height value difference of not more than 0.05mm from each measurement position. The print base slope reference point is at the center point of the print base. The position of the other corner of the base will be adjusted in height with a stepper motor drive.

Abstract:
The binding of the cyclic AMP receptor protein (CRP) to symmetrical synthetic DNA-binding sites was investigated with a gel-retardation assay. A set of ten different sequences was employed, comprising all base permutations at positions 2, 4, and 5 of the consensus sequence 5′(TGTGA)3′. We show that: (i) CRP has a higher affinity for the completely symmetrical site than towards the lac wild-type site; (ii) base substitutions at position 2 lead to either a complete loss of specific CRP binding (G—C), a reduction in specific CRP binding (G—A) or only marginal effects on specific CRP binding (G—T); (iii) changes at position 4 abolish (G—C; G—A) or reduce (G—T) specific CRP binding; and (iv) base permutations at position 5 reduce specific CRP binding, but never completely abolish it. Thus position 4, and to a lesser extent position 2, in the DNA consensus sequence are the most crucial ones for specific binding by CRP.

AbstractAn examination of Pashto’s second-position pronominal clitics reveals that they are best regarded as agreement morphemes rather than as arguments of the verb. By base-generating these clitics as heads of agreement projections, their appearance in second position may be derived without recourse to phonological reordering rules, which have been necessary in earlier analyses.

Abstract:
Two life positions of fossil naticid opercula are recognized in Pliocene deposits of Hokkaido, northern Japan. In one position, the operculum seals the aperture. In the other position, the operculum is pressed against the shell base adjacent to the aperture. The death position of the head-foot mass can be reconstructed from the two opercular positions, which coincide, respectively, to naticids that died with the head-foot mass retracted into the shell, and those that died with it entirely extended from the shell.

Abstract:
This personal account summarizes our recent progress in the development of C–H transformations. We achieved ortho-selective C–H borylations and silylations by using Lewis acid–base interaction between two substrates and we achieved meta- and ortho-selective C–H borylations by using hydrogen bonding or Lewis acid–base interaction between a hydrogen donor or Lewis acid unit of a ligand and a functional group of a substrate. Regioselective C–H trifluoromethylations and related reactions of six-membered heteroaromatic compounds were realized at their 2- and 4-positions and at their benzylic positions. In addition, we developed C–H transformations directed towards the synthesis of organic functional materials, such as highly soluble polyimides or π-conjugated molecules containing either heteroatom(s) or a Lewis acid–base interaction.1 Introduction2 Regioselective C–H Transformations Controlled by Noncovalent Bond Interactions2.1 Regioselective C–H Transformations Controlled by Lewis Acid–Base Interaction between Two Substrates2.2 Regioselective C–H Transformation Controlled by Hydrogen Bonding between Ligand and Substrate2.3 Regioselective C–H Transformations Controlled by Lewis Acid–Base Interactions between Ligands and Substrates3 Trifluoromethylation and Related Transformations of Six-Membered Heteroaromatic Compounds3.1 2-Position-Selective C–H Trifluoromethylation of Six-Membered Heteroaromatic Compounds3.2 4-Position-Selective C–H Trifluoromethylation of Six-Membered Heteroaromatic Compounds3.3 Benzyl Position-Selective C–H Trifluoromethylation of Six-Membered Heteroaromatic Compounds4 C–H Transformations Leading to the Synthesis of Organic Functional Materials4.1 Heteroatom-Containing π-Conjugated Molecules4.2 π-Conjugated Molecules Containing a Lewis Acid–Base Interaction4.3 Soluble Polyimide Derivatives5 Conclusions

Abstract:
Abstract CRISPR/Cas base editors promise nucleotide-level control over DNA sequences, but the determinants of their activity remain incompletely understood. We measured base editing frequencies in two human cell lines for two cytosine and two adenine base editors at ∼14 000 target sequences and find that base editing activity is sequence-biased, with largest effects from nucleotides flanking the target base. Whether a base is edited depends strongly on the combination of its position in the target and the preceding base, acting to widen or narrow the effective editing window. The impact of features on editing rate depends on the position, with sequence bias efficacy mainly influencing bases away from the center of the window. We use these observations to train a machine learning model to predict editing activity per position, with accuracy ranging from 0.49 to 0.72 between editors, and with better generalization across datasets than existing tools. We demonstrate the usefulness of our model by predicting the efficacy of disease mutation correcting guides, and find that most of them suffer from more unwanted editing than pure outcomes. This work unravels the position-specificity of base editing biases and allows more efficient planning of editing campaigns in experimental and therapeutic contexts.

Abstract:
The association between tongue-base position and craniofacial morphology was investigated in 35 preschool children (17 girls and 18 boys), 3 to 6 years of age, by the lateral cephalometric radiographs. There was no statistical difference in the measurements of those between girls and boys. Posterior facial height, nasal floor length, mandibular corpus length and tongue-base position were positively correlated with age, and tongue-base position was correlated with maxillary position, vertical mandibular rotation and the nasopharyngeal airway space. The results of this study showed that tongue-base position influenced maxillo-mandibular growth even in young preschool children.

Abstract:
The conserved positions of the eukaryotic cytoplasmic initiator tRNA have been suggested to be important for the initiation of protein synthesis. However, the role of these positions is not known. We describe in this report a functional analysis of the yeast initiator methionine tRNA (tRNA(iMet)), using a novel in vivo assay system which is not dependent on suppressor tRNAs. Strains of Saccharomyces cerevisiae with null alleles of the four initiator methionine tRNA (IMT) genes were constructed. Consequently, growth of these strains was dependent on tRNA(iMet) encoded from a plasmid-derived gene. We used these strains to investigate the significance of the conserved nucleosides of yeast tRNA(iMet) in vivo. Nucleotide substitutions corresponding to the nucleosides of the yeast elongator methionine tRNA (tRNA(MMet)) have been made at all conserved positions to identify the positions that are important for tRNA(iMet) to function in the initiation process. Surprisingly, nucleoside changes in base pairs 3-70, 12-23, 31-39, and 29-41, as well as expanding loop I by inserting an A at position 17 (A17) had no effect on the tester strain. Nucleotide substitutions in positions 54 and 60 to cytidines and guanosines (C54, G54, C60, and G60) did not prevent cell growth. In contrast, the double mutation U/rT54C60 blocked cell growth, and changing the A-U base pair 1-72 to a G-C base pair was deleterious to the cell, although these tRNAs were synthesized and accepted methionine in vitro. From our data, we suggest that an A-U base pair in position 1-72 is important for tRNA(iMet) function, that the hypothetical requirement for adenosines at positions 54 and 60 is invalid, and that a U/rT at position 54 is an antideterminant distinguishing an elongator from an initiator tRNA in the initiation of translation.

Abstract:
To solve the early destruction problems occurred when overlaying asphalt pavement structure containing semi-rigid base on broken cement concrete pavement, finite element software is used to compare the stress characters between the repaving pavement and ordinary pavement, and analyze the repaving structures under different loads and different road transverse grade. It shows that the value of compressive stress at the top of base of repaving pavement is significantly higher than that of ordinary pavement, meanwhile, its value of tensile stress of base bottom is lower; the asphalt surface and new base top of repaving pavement need to bare a high value of shear stress and compressive stress under overload, so it’s prone to splitting failure in the base. With the increase of transverse grade, both the shear stress difference of road surface and maximum vertical compressive at top of the base increase in a lower position, but the situation is opposite in the higher position.

Abstract:
Macroscopic and microscopic properties of molecular and solid-state systems are intimately related to the their electronic structure. The electron position and spin densities, which represent the probability distributions to find all or unpaired electrons in the space, contain information concerning several chemical-relevant properties, such as the chemical bonding and the magnetic behaviour. Understanding the fine atomic-level mechanism behind these properties is a key step to design chemical modifications to properly tune and develop materials or molecules with specific features. Topological descriptors can be used to extract information from these electron distributions. In this work, novel applications of the source function descriptor have been developed to gain further insights on the electron and spin density-related properties. These developments, together with other topological descriptors, were used to get further insights on relevant chemical systems. Firstly, the source function reconstruction was enlarged to a multi-dimensional grid of points with a particular focus on the two-dimensional maps. This analysis allows to see the ability of chosen subsets of atoms to reconstruct the density in the selected area within a cause-effect relationship and to rationalise the chemical or magnetic behaviours. The source function partial reconstructed maps depict if in a molecular region the atomic contributions are important, modest or negligible. Besides, they may also be useful for a proper selection of the reference points and for a full understanding of the source function percentages analysis. In fact, the choice of the reference point where to reconstruct the studied density is neither easy nor objective for non-standard situations, such as for the spin density. This novel application was applied to the study of the spin density on a couple of azido Cu complexes. The source function partial reconstructed maps allow to unravel the different role played by the paramagnetic centre Cu and the ligand atoms and to explain the spin transmission mechanism at a molecular level. Moreover, they enable to highlight the nature of the spin density differences between the two complexes and among adopted computational approaches. DFT functionals tend to over-delocalise the spin density towards the ligand atoms introducing a biased spin-polarization mechanism between the Cu and the ligand atoms. The same descriptor was then applied to the study of the hydrogen bonds in the DNA base pairs. The source function reveals the delocalised nature of these interactions, highlighting that distant groups and rings have non-negligible effects on the reconstruction of the electron density in the intermolecular region. Besides, the analysis demonstrates that the purine and pyrimidine bases equally contribute to the reconstruction of the electron density at the hydrogen bond critical points. The source function also reveals that subtle variations of the atomic source contributions occur when the pairs are ionized, revealing that sources and sinks effects redistribution plays an important role in the stabilization of the DNA base pairs. The source function was also used to develop a method to extract full population matrices purely based on the electron density distribution and then amenable to experimental determination. The peculiar features of this descriptor, in particular the cause-effect relationship, assign a profound chemical meaning to the matrix elements in contrast with other population analyses such as the Mulliken's one, where the matrix elements are associated to orbital overlaps. The latest breakthroughs on the development of this method are shown together with some numerical examples on very simple compounds. The full population matrices obtained using the source function descriptor are able to retrieve the major chemical features. A detailed analysis on the intermolecular interactions involved in the in vivo molecular recognition of the antimalarial drug chloroquine with the heme moiety has been carried out using a combined topological-energetic analysis. This work reveals that charged-assisted hydrogen bonds set up between the lateral chains of the chloroquine and the propionate group of the heme are the most important interactions in the drug:substrate recognition process.

Abstract:
Chaque année en Europe, 1.300.000 accidents de la route ont comme conséquence 1.700.000 blessés. Le coût financier d'accidents de la route est évalué à 160 milliards d'euros (approximativement le même coût aux Etats-Unis). VANET (Vehicular Ad-hoc NETwork) est une des technologies clés qui peut permettre de réduire d'une façon significative le nombre d'accidents de la route (e.g. message d'urgence signalant la présence d'un obstacle ou d'un véhicule en cas de brouillard). En plus de l'amélioration de la sécurité et du confort des conducteurs et des passagers, VANET peut contribuer à beaucoup d'applications potentielles telles que la prévision et la détection d'embouteillages, la gestion d'infrastructure de système de transport urbain (e.g. système de transport intelligent multimodal) etc. Dans cette thèse, je présenterai un système embarqué dédié à la communication inter-véhicule particulièrement pour les applications sécuritaires de passagers et de conducteurs. Nos efforts de recherche et de développement sont centrés sur deux principaux objectifs : minimiser le temps de latence intra-noeud et le délai de communication inter-véhicule en prenant en compte le changement dynamique du VANET. De ce fait pour atteindre ces objectifs, des nouvelles approches (e.g. inter-couche 'Cross-layering') ont été explorées pour respecter les contraintes de ressource (QoS, mémoire, CPU et énergie de la communication inter-véhicule) d'un système embarqué à faible coût. Le système de communication embarqué proposé comporte deux composants logiciels principaux : un protocole de communication dénommé CIVIC (Communication Inter Véhicule Intelligente et Coopérative) et un système d'exploitation temps réel appelé HEROS (Hybrid Event-driven and Real-time multitasking Operating System). CIVIC est un protocole de communication géographique à faible consommation énergétique et à faible temps de latence (délai de communication). HEROS gère contextuellement l'ensemble du système (matériel et logiciel) en minimisant le temps de latence et la consommation des ressources (CPU et mémoire). En outre, le protocole de communication CIVIC est équipé d'un système de localisation LCD-GPS (Low Cost Differential GPS). Pour tester et valider les différentes techniques et théories, la plateforme matérielle LiveNode (LImos Versatile Embedded wireless sensor NODE) a été utilisée. En effet, la plateforme LiveNode permet de développer et de prototyper rapidement des applications dans différents domaines. Le protocole de communication CIVIC est basé sur la technique de 'broadcast' à un saut ; de ce fait il est indépendant de la spécificité du réseau. Pour les expérimentations, seule la norme d'IEEE 802.15.4 (ZigBee) a été choisie comme médium d'accès sans fil. Il est à noter que le médium d'accès sans fil ZigBee a été adopté comme le médium standard pour les réseaux de capteurs sans fil (RCSFs) et le standard 6LoWPAN ; car il est peu coûteux et peu gourmand en énergie. Bien que le protocole de communication à l'origine soit conçu pour répondre aux exigences de VANET, ses domaines d'application ne sont pas limités à VANET. Par exemple il a été utilisé dans différents projets tels que MOBI+ (système de transport urbain intelligent) et NeT-ADDED (projet européen FP6 : agriculture de précision). Les VANETs et les RCSFs sont les réseaux fortement dynamiques, mais les causes de changement topologique de réseau sont différentes : dans le réseau VANET, il est dû à la mobilité des véhicules, et dans le RCSF, il est dû aux pannes des noeuds sans fil. Il est à noter que le VANET et le RCSF sont généralement considérés comme un sous-ensemble du réseau MANET (réseau ad-hoc mobile). Cependant, ils sont réellement tout à fait différents du MANET classique, et leurs similitudes et différences seront expliquées en détail dans la thèse. La contribution principale de mes travaux est le protocole CIVIC, qui échange des messages en basant sur l'information géographique des noeuds (position). Les travaux relatifs de la thèse se concentreront sur les techniques, les problèmes et les solutions de routage géographique, mais d'autres techniques de routage seront également adressées. Quelques projets relatifs au protocole de communication ont été étudiés mais leur implémentation et les aspects d'expérimentation n'ont pas été détaillés. Enfin la thèse ne présente pas simplement les techniques et concepts adoptés, et les résultats de simulation, mais en outre, elle expliquera les aspects techniques importants pour la réalisation et l'expérimentation des différentes applications ainsi que les résultats concrets obtenus.

Abstract:
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>Esta tese é composta por três artigos que permitiram avaliar o efeito da exposição ao tabagismo durante a gestação e no início da infância sobre o crescimento linear e ganho de peso do nascimento à adolescência, além de verificar o efeito do nível socioeconômico no início da infância e da mobilidade social sobre a adiposidade até a adolescência. Foram utilizados para este fim os dados de uma coorte de crianças nascidas entre 1994 e 1999 na cidade de Cuiabá-MT. Essas crianças fizeram parte de um estudo de base populacional realizado na cidade de Cuiabá, entre 1999 e 2000, com 2405 crianças (0 a 5 anos) e foram selecionadas aleatoriamente em unidades básicas de saúde quando da vacinação. As mães foram entrevistadas após a vacinação, quando foram obtidos dados relativos à exposição ao tabagismo gestacional, tabagismo passivo, nível socioeconômico das famílias e dados antropométricos. Entre 2009 e 2011, após aproximadamente 11 anos, essas crianças foram localizadas por meio do Censo Escolar e então 1716 adolescentes entre 10 e 17 anos de idade (71,4% da população) foram reavaliados nas escolas da rede pública e privada de Cuiabá, de 18 municípios do estado e outras 5 capitais do país. A análise por modelos lineares de efeitos mistos permitiu verificar a mudança de estatura e Índice de Massa Corporal (IMC) entre o nascimento e a adolescência. O primeiro e o segundo artigo desta tese avaliaram o efeito da exposição ao tabagismo materno durante a gestação e no início da infância sobre o crescimento linear e o IMC entre o nascimento e a adolescência. Crianças expostas ao tabagismo materno durante a gestação e no início da infância apresentaram menor estatura desde o nascimento até a adolescência quando comparadas às crianças não expostas. Quanto à adiposidade, entre o nascimento e a infância a mudança do IMC foi similar entre as crianças expostas e não expostas ao tabagismo materno, porém, entre a infância e a adolescência, aquelas expostas apenas durante a gestação mostraram maior ganho de IMC. Em conjunto, os dados corroboram o efeito deletério do tabagismo sobre o crescimento, efeito já bastante estudado, mas também indicam que avaliar e comparar exposição gestacional com pós-gestacional é importante, dado que seus efeitos parecem ser diferentes. O terceiro artigo avaliou o efeito do nível socioeconômico no início da infância e da mobilidade social entre a infância e a adolescência sobre o IMC do nascimento à adolescência. Para avaliar o nível socioeconômico, as famílias foram classificadas em nível econômico alto, médio e baixo, a partir do Critério de Classificação Econômica Brasil. Foi observada expressiva mobilidade social na população, principalmente entre os de menor nível econômico. Houve maior aumento do IMC entre o nascimento e a adolescência entre aqueles de maior nível econômico na infância e aqueles que permaneceram nas classes mais elevadas, indicando que a posição inicial foi o maior determinante das mudanças observadas no IMC.<br>This thesis consists of three papers that allowed us to evaluate the effect of exposure to smoking during pregnancy and early childhood on linear growth and weight gain from birth to adolescence, and to verify the effect of socioeconomic position in early childhood and social mobility on adiposity until adolescence. For this purpose, we used the data of a cohort of children born between 1994 and 1999 in the city of Cuiabá. They were part of a population-based study conducted with 2,405 children (05 years) who attended one of the ten basic health units selected for vaccination in the city of Cuiabá between 1999 and 2000. Between 2009 and 2011, after approximately 11 years, these children were located through the School Census; thus, 1,716 adolescents aged 10 to 17 years old (71.4% of the population) were reassessed in the public and private schools of Cuiabá, of 18 counties in the state and five other capitals in the country. The mothers were interviewed after vaccination to obtain data regarding their exposure to smoking during pregnancy, passive smoking, socioeconomic status, and anthropometric information. The linear mixed-effects analysis showed the change in height and body mass index (BMI) from birth to adolescence. The first and second articles in this thesis evaluate the effect of exposure to maternal smoking during pregnancy and early childhood on linear growth and BMI from birth to adolescence. Children exposed to maternal smoking during pregnancy and early childhood were shorter from birth to adolescence than the children not exposed. As for adiposity between birth and childhood, the BMI change was similar between children exposed and not exposed to maternal smoking; however, between childhood and adolescence, those exposed only during gestation showed greater gains in BMI. Together, these data not only confirm the deleterious effect of smoking on growth, which has been extensively studied, but also indicate that it is important to evaluate and compare gestational to post-pregnancy exposure because their effects seem to be different. The third paper examines the effect of socioeconomic status in early childhood and social mobility from childhood to adolescence on BMI from birth to adolescence. To assess socioeconomic position, the families were classified into high, medium, and low economic levels based on the Brazil Criterion of economic classification. We observed significant social mobility in the population, especially among the lower economic group. We observed a greater increase in BMI from birth to adolescence among those from higher socioeconomic position in childhood and those who remained in the higher classes, indicating that the starting position was the major determinant of the observed changes in BMI.

Abstract:
<p>This thesis considers control of moored marine structures, referred to as position mooring. Moored marine structures can take on a number of different forms, and two applications are considered in this work, namely aquacultural farms and petroleum producing vessels. It is anticipated that future aquacultural farms will be significantly larger than the existing ones, and placed in much more exposed areas. Hence, there is a significant technology transfer potential between the two seemingly different fields of aquaculture and petroleum exploitation.</p><p>Today’s implemented state of the art positioning controllers use predetermined safety regions and gain-scheduling for evaluating the necessary thruster force for the vessel to operate safely. This represents a suboptimal solution; the operator is given a significant number of variables to consider, and the thrusters are run more than necessary. Also, it is likely that a more conservative controller regime does not necessarily increase the overall reliability of the structure as compared with a less conservative but better designed controller.</p><p>Motivated by this, a new control methodology and strategy for position mooring is developed. Two controllers using information about the reliability of the mooring system are implemented and tested, both via numerical simulations and model scale experiments. The first controller developed uses a reliability criterion based on the tension in the mooring system as a pretuning device. A nonlinear function based on the energy contained by the system is included in the controller to ensure that the thrusters are run only when needed. The controller is an output-feedback controller, based on measurement of position and estimated values of the velocities and slowly varying environmental loads. The second controller developed contains the reliability criterion intrinsically, thus, less pretuning is needed. The backstepping technique is applied during the design process, and the controller has global asymptotical stability properties.</p>

In this thesis we want to create scalable, fault-tolerant and self-configuring dictionaries that can be deployed in a wide range of networks, including highly dynamic networks with frequent membership changes, like peer-to-peer overlay networks or wireless ad hoc networks. In recent years, distributed hash tables (DHTs) have emerged as a solution to implement large-scale dictionaries. However, given the existing bandwidth limitations, updating routing information in DHTs remains a challenge. Position-based routing schemes arise as an attractive solution to this problem, due to inexpensive and ubiquitous localization mechanisms. Positional information enables the creation of oblivious (or memoryless) routing schemes, where the coordinates of the current forwarding node, of its neighbors and of the destination, suffice to determine the next hop. Such routing schemes are very suitable to rapidly changing networks, because they require very little control information. We argue in this thesis that we can use positional information to efficiently support routing and DHT operation in wireless ad hoc and in wired networks, whenever position of nodes reflects network topology. To support this claim, we create and evaluate a number of algorithms that simultaneously support routing and DHT operation in both types of networks. % As an interesting result of our work, we can combine solutions into a single architecture that spans wired and wireless networks. This architecture can provide a seamless integration and use of a position-based DHT, despite the access network of the peer nodes

Abstract:
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2004.<br>Includes bibliographical references (p. 129-131).<br>This thesis presents the design and development of a novel laser-speckle-based position sensing technique. In our prototype implementation, a He-Ne laser beam is directed at the surface of an air-bearing spindle. An imaging system is set up to capture speckle patterns scattered from the spindle surface. These patterns are highly correlated over small angular displacements of the spindle. We use correlation-based image-processing algorithms to measure offsets between the speckle patterns. These offsets are calibrated against the counts of a commercial incremental optical encoder. A custom-built bicell photointerrupter unit is used as a reference sensor for the incremental optical encoder. To test for the control performance of this speckle-based sensor, we have constructed a transmission drive to run the air-bearing spindle. Our speckle-based metrology system is able to run at update rates of 10 Hz with a measured closed loop -3 dB bandwidth of about 2 Hz. Using a real-time processor interfaced with a desktop PC, we have implemented a novel algorithm that interpolates position estimates with respect to two pre-stored global images. We predict that this technique can potentially achieve resolutions of 0.1 [mu]m for translational and 5 [mu]rad for rotational motion. The limitation of our current implementation is the low update rates resulting from the time-intensive nature of correlation-based methods. Possible methods to overcome this limitation are addressed and ideas for follow-on work are presented.<br>by Vijay Shilpiekandula.<br>S.M.

Abstract:
Mestrado em Engenharia Eletrónica e Telecomunicações<br>Resumo não disponível<br>The widespread use of LED as arti cial illumination lead to the development of indoor positioning systems using visible light. On this work we gathered information on strategies and sensors used in visible light positioning (VLP). As such, we propose to estimate a robots position based on visible light communication (VLC) using a prototype developed in previous works. The work was divided in four stages. Initially, we veri ed that the prototype used was suitable to estimate its position. In order to overcome the prototype's limitations, a simulation environment was developed, where similar structures were tested. This allowed the comparison between the results obtained using the prototype and those from the simulator. At last, a noise model was implemented on the simulator to verify its in uence on the position estimation. The results show the viability of implementing VLP using a simple sensor based on a set of photo-diodes placed over a hemispherical dome, yielding a low-cost solution for VLP. When comparing the results obtained with the prototype and the simulator, we veri ed that the response is identical. With the implementation of the noise model, the results show an error of a few centimetres. We concluded that the photo-diodes eld of view is important when the position is estimated. The sensors eld of view should be big enough to intercept others in order to prevent blind spots but not too big since it would lead to errors because all sensors would receive signal.

Abstract:
ABSTRACT This article selects a certain gas pipeline system, the director of the line on material X60 steel and typical process pipeline structure of 20 # steel elbow, yard by the metallurgical structure observation of the typical sampling position and hardness tests, hydrogen permeation test compared the hydrogen and hydrogen content of X60 steel base, girth weld and hydrogen embrittlement sensitivity of 20 # steel elbow position size. The risk of hydrogen embrittlement at sensitive sites in hydrogen environment was studied by notch tensile test. The results show that the hydrogen diffusion coefficient of base metal and weld of X60 steel is higher, and the hydrogen concentration adsorbed on the surface is lower. The hydrogen diffusion coefficient of 20# steel is low, and the concentration of hydrogen adsorbed on the surface is high, which indicates that the hydrogen trap content in 20# steel is high, and it is easier to capture hydrogen atoms, and the possibility of hydrogen embrittlement exists. The notch tensile test of 20# steel at a sensitive position was carried out in a medium with a total pressure of 6 MPa and a volume fraction of 3% hydrogen. Compared with the similar experimental results in the air, the strength and plasticity of 20# steel have no obvious changes. The results show that the risk of hydrogen embrittlement of 20# steel is low in the mixed hydrogen transportation environment.

Abstract:
We present a new method to improve the representational power of the features in Convolutional Neural Networks (CNNs). By studying traditional image processing methods and recent CNN architectures, we propose to use positional information in CNNs for effective exploration of feature dependencies. Rather than considering feature semantics alone, we incorporate spatial positions as an augmentation for feature semantics in our design. From this vantage, we present a Position-Aware Recalibration Module (PRM in short) which recalibrates features leveraging both feature semantics and position. Furthermore, inspired by multi-head attention, our module is capable of performing multiple recalibrations where results are concatenated as the output. As PRM is efficient and easy to implement, it can be seamlessly integrated into various base networks and applied to many position-aware visual tasks. Compared to original CNNs, our PRM introduces a negligible number of parameters and FLOPs, while yielding better performance. Experimental results on ImageNet and MS COCO benchmarks show that our approach surpasses related methods by a clear margin with less computational overhead. For example, we improve the ResNet50 by absolute 1.75% (77.65% vs. 75.90%) on ImageNet 2012 validation dataset, and 1.5%~1.9% mAP on MS COCO validation dataset with almost no computational overhead. Codes are made publicly available.

Delbridge, Victoria. Enhancing the financial position of cities: Evidence from Hargeisa. UNHabitat, 2022. http://dx.doi.org/10.35489/bsg-igc-wp_2022/4.

Full text
Abstract:
The City of Hargeisa, despite being in the very early stages of enhancing its financial position, has achieved significant reform in just a few years since its democratic establishment in 2002. The successes achieved are even more remarkable, considering the fragile context of Somaliland after 30 years of civil war within Somalia, which left widespread destruction and devastation in the city. This is compounded by Somaliland’s lack of recognition as a sovereign state by the international community. The case provides an illustrative example of leveraging urbanisation to raise municipal revenues for public service delivery, and in building local government legitimacy to better deliver to the populace. Given the context, the reforms are those that are easy to implement and effective, including the application of a simple digitised accounting and billing system, and a fit-for-purpose area-based property tax system. Where other cities have struggled to service more people with a stagnant revenue base, Hargeisa’s reforms have meant that population growth has resulted in increased revenues from property taxes and daily vendor collections. At the same time, private contributions of land on the peri-urban fringes offer an opportunity for in-kind land value capture and planned development in the future. Their successes are reinforced by the legitimacy built through participatory governance, which demonstrates what is achievable when communities, local government and the private sector work together. While Hargeisa has made progress on the basics of own-source revenue, much more is yet to be done to finance future development. Local government capital expenditure, for instance, is often far below what is budgeted. This is influenced by public demand for current and visible service delivery over and above less visible long-term investments. Furthermore, due to Somaliland’s internationally unrecognised status as an independent country, Hargeisa received limited development assistance when compared to other cities in similar contexts. However, a small coordinated effort through a coalition of UN agencies has fundamentally shaped some of the city’s reforms. As the country begins to formalise its financial sector, opening up to commercial banking and international investment, development support will be needed to ensure local governments and the private sector are able to capitalise on the opportunities this presents.

Abstract:
For the first time, a Chinese company—Huawei—is set to lead the global transition from one key national security infrastructure technology to the next. How did Washington, at the beginning of the twenty-first century, fail to protect U.S. firms in this strategic technology and allow a geopolitical competitor to take a leadership position in a national security relevant critical infrastructure such as telecommunications? This policy brief highlights the characteristics of 5G development that China leveraged, exploited, and supported to take the lead in this key technology. The Huawei case study is in some ways the canary in the coal mine for emerging technologies and an illustration of what can happen to U.S. competitiveness when China’s companies do not have to base decisions on market forces.

Full text
Abstract:
In recent years, Indonesia has introduced reforms to its bureaucracy in response to critiques of the quality of government policy design and delivery. The Grand Design of Bureaucratic Reform strategy seeks to reduce the number of civil servants employed in administrative or managerial positions (structural appointments) in favour of skills-based recruitment into ‘functional’ positions. Specifically, the introduction of the ‘policy analyst’ position as a functional position in the civil service has sought to improve evidence-based policy making and the quality of policy outcomes, by incorporating merit-based recruitment, appointment and promotion. The role of functional policy analysts (Jabatan Fungsional Analis Kebijakan or JFAKs) is to assist policy makers in identifying policy issues, analyse evidence available on these issues, and ultimately make policy recommendations. This report overviews the recent experiences of different policy analyst cohorts since the role’s creation in 2015. It investigates these experiences to better understand the extent to which policy analysts are playing the role intended for them, and the factors enabling or inhibiting this.

Full text
Abstract:
Cable-based technologies can be used to detect leaks, ground movement, and third-party interference. Significant technical challenges exist for installing cables at precise positions along existing pipelines. This project aimed to advance technology that can enable retrofitting existing pipelines with cable-based sensors. One of the key gaps is the ability to accurately locate the lateral position and depth-of-cover of a pipeline. Testing was performed on two pipelines to evaluate the performance of different pipeline location technologies to provide pipeline operators with data that can be used in evaluating potential retrofit applications. This work aimed to move the needle closer towards a full pipeline retrofit of cable-based technologies.

Abstract:
At the start of 2025, the Irish economy is in a strong position. Unemployment stands at 3.9 per cent, while real income growth is set to exceed 3.5 per cent in the current year. Exchequer returns continue to increase quite significantly for the opening period of the present year. Therefore, as a baseline, we expect modified domestic demand (MDD) to increase by 3.0 per cent in 2025 and 2.8 per cent in 2026. These forecasts are conducted on the assumption of no trade tariffs being imposed between the United States (US) and the European Union (EU). However, the international climate is particularly fraught at the present time, with the incoming US administration outlining a series of tariffs on certain countries. The likely deterioration in global trading conditions, which will almost certainly ensue from any trade war, will have adverse implications for the domestic economy. Furthermore, the general uncertainty caused by a changing US economic policy is likely to subdue global activity, lower investment and consumption. We build this into our base case forecasts regardless of the final tariff position. The overall impact of a tariff war on the Irish economy will be compounded if the US specifically targets pharmaceutical products as part of any proposed tariff strategy. We provide an alternative series of forecasts for the traded sector of the Irish economy, highlighting the potential implications of the imposition of a 25 per cent bilateral tariffs on goods. In this alternative scenario, drawing on Egan and Roche (2025), MDD growth is forecast to be 2.8 per cent in 2025 and 2.1 per cent in 2026. Housing supply in 2024 was somewhat disappointing, with completions coming in at 30,330 units, heightening fears that housing costs will continue to escalate in the domestic economy. While numerous factors are likely to be affecting housing supply, in two Boxes in this Commentary, we address the ‘funding gap’ and the policy around rent controls, both of which are likely to weigh on supply.1 A further Box to the Commentary by O’Shea assesses the contribution to domestic output growth of increasing participation rates among the older cohorts of the Irish labour market.
