Micro-scale monitoring in an urban area using vehicular sensor network
Creators: name: Milojevic, Milica
Publisher: name: Imperial College London
Year: 2017

description: One of the emerging problems facing populated urban areas represents high level of the air pollution. Current monitoring approaches assume processing of pollution data in a centralised manner, however due to external factors (e.g. current atmospheric conditions) the air pollution level can have fast fluctuations inside a street which might lead to disparity of the pollution levels in neighbouring streets. This thesis proposes a decentralised monitoring framework that enables harvesting of the pollution data, its processing, and dissemination of early warnings to the Static Monitoring Units (SMU) when the onsets of hazardous air pollution concentration are detected at the street (micro-scale) level. The proposed air pollution monitoring framework relies on a Vehicular Sensor Network infrastructure where vehicles have limited on-board resources, such as processing, battery power and storage. Three aspects of the micro-scale air pollution monitoring have been investigated. The Decentralised data Dissemination and Harvesting (DDH) is a single-hop dissemination mechanism which enables the nodes to decide whether they should harvest the data based on their current position and movement direction. This mechanism identifies the streets that nodes need to monitor by comparing the amount of stored pollution data with the one harvested from other nodes in the network. The Decentralised Data Fusion (DDF) algorithm is developed to fuse the delayed pollution data that arrives from other nodes in the network. The algorithm uses the Delayed State Information Filter to refine sensor measurements and applies an interpolation technique to interpolate the missing data in the time gaps which occur as a consequence of receiving delayed data. The proposed algorithm augments the pollution data history at the slight cost of data accuracy. The Decentralised Dissemination of Warnings (DDW) is a beaconless, multihop dissemination mechanism designed to relay early warnings to the SMUs. Mobile nodes calculate the time interval (waiting time) that they need to wait before they rebroadcast the warning message. The waiting time is calculated by taking into account the distance between sending and receiving nodes, and nodes’ distances to the SMUs. The DDW mechanism ensures that high number of non-duplicated warnings is received at the collection points (SMUs). The proposed framework enables efficient utilisation of node’s on-board resources in terms of transmitting and processing activity, and data storage. It reduces the number of mobile nodes required for monitoring purposes without losing the volume of the relevant collected pollution data. Using uncontrolled mobile nodes and their mobility, the framework enables reporting the hazardous pollution levels in near real-time.

description: Various 3D semantic attributes such as segmentation masks, geometric features, keypoints, and materials can be encoded as per-point probe functions on 3D geometries. Given a collection of related 3D shapes, we consider how to jointly analyze such probe functions over different shapes, and how to discover common latent structures using a neural network --- even in the absence of any correspondence information. Our network is trained on point cloud representations of shape geometry and associated semantic functions on that point cloud. These functions express a shared semantic understanding of the shapes but are not coordinated in any way. For example, in a segmentation task, the functions can be indicator functions of arbitrary sets of shape parts, with the particular combination involved not known to the network. Our network is able to produce a small dictionary of basis functions for each shape, a dictionary whose span includes the semantic functions provided for that shape. Even though our shapes have independent discretizations and no functional correspondences are provided, the network is able to generate latent bases, in a consistent order, that reflect the shared semantic structure among the shapes. We demonstrate the effectiveness of our technique in various segmentation and keypoint selection applications.

Assessing and improving methods for the voluntary reporting of errors in healthcare, preventing harm in surgery and the measurement of avoidable death
Creators: name: Howell, Ann-Marie Ruth
Publisher: name: Imperial College London
Year: 2016

description: Since the government paper “An organization with a memory” the National Health Service has sought to prevent healthcare-related harm. It is unclear, a decade later, whether patients are now “safer”. One of the principal problems in this developing field is the imprecision with which harm is measured. All methods contain epidemiological flaws that reduce their utility. The current methods such as retrospective case note review or voluntary safety reporting systems are cumbersome or prone to non-responder bias. This thesis reviewed the success of innovations to reduce surgical adverse events. It assessed methods of measurement of patient safety in healthcare with a focus on voluntary reporting and retrospective case note review. It evaluated the utility of the National Reporting and Learning System (NRLS) to increase the understanding and learning from the available data. A mixed method approach was used with both qualitative and quantitative techniques. Methods for measuring avoidable death at a hospital level involving explicit retrospective case note review were developed In a systematic review current methods for preventing surgical harm were found to be limited in their efficacy to statistically reduce morbidity and mortality. The NRLS data were found to be unable to correlate with existing measures of hospital quality. A system of improved classification of surgical adverse events was developed. International expert review delineated the future role of reporting systems. A novel tool for performing case note reviews in a reproducible fashion was validated and shown to elucidate efficiently the avoidability of hospital deaths. By tailoring and improving reporting systems and retrospective case note review methods, this thesis has been able to demonstrate improved measurement of harm and avoidable death. This will provide a better understanding of the scale and nature of healthcare-related harm.
A scientific impresario: Archie Clow, science communication and BBC Radio, 1945–1970
Creators: name: Keller, Jared Robert
Publisher: name: Imperial College London
Year: 2017

description: From the end of the Second World War to the close of the 1960s, the BBC’s approach to spoken-word science programming changed considerably. Whereas the BBC of the late 1940s saw itself as a platform from which scientists could deliver authoritative talks on science directly to the British public, the BBC of the late 1960s saw its role as the examination and interrogation of science through journalistic programmes presented by professional broadcasters or science journalists. Utilizing a wide range of archival and primary sources, this thesis details the tensions and deliberations which brought about this transition within BBC radio. In particular it focuses on the career of Archie Clow, a science producer at the BBC from 1945 to 1970 who was instrumental in both defining and implementing the BBC’s approach to science broadcasting during this period. His career serves as a lens through which the BBC’s changing conception of the value and purpose of science programming can be examined. In the early post-war period Clow fancied himself a ‘scientific impresario’ charged with the identification and recruitment of eminent scientists, yet by the end of the 1960s many of his colleagues considered themselves journalists rather than impresarios. Archival records show that this had much to do with a transition within the wider BBC toward a more journalistic, news-style approach to spoken-word programming. The thesis argues that by the end of this period the BBC saw itself as a communicator of science in its own right. It further argues that as the BBC moved to mediate science and scientists on behalf of the British public, scientists increasingly lost control over the framing and delivery of science programming, eventually finding themselves largely reliant upon and beholden to professional broadcasters.
Time-dependent metabolic phenotyping of inflammatory dysregulation
Creators: name: Wolfer, Arnaud
Publisher: name: Imperial College London
Year: 2016

description: A rich and functional description of a patient health status is the fundamental basis for the personalisation of treatment and the targeting of interventions. The function of inflammation in the healing process as well as its involvement in most major diseases is well established, yet the specific mechanism by which it contributes to the pathogenesis is still not fully understood. If conditions arising from a dysregulation of the inflammatory process are to be treated before they become irreversible, a novel understanding of these pathologies must be achieved and a stratification of patients based on their inflammatory status undertaken. The work presented in this thesis aims to deliver new analytical and statistical approaches to support the investigation of the time-dependent dysregulation of inflammation. Lipid mediators have been described as exerting a major role in the initiation and regulation of the inflammatory response, yet analytical platforms for their large-scale characterisation in human biofluids are lacking. This thesis reports the validation of an assay for the simultaneous quantification of pro- and anti-inflammatory signalling molecules in multiple human biofluids. The coverage of the assay in each biofluid is subsequently established, characterising inflammatory signalling across biological compartments. A second study explores the assay’s applicability in a clinical context; investigating the relationship between lipid mediators, current clinical markers of inflammation and post-operative complications. Characterising the interplay between signalling and regulatory networks is key to understanding a living system’s response to perturbations, yet few statistical approaches are suited for the detection of time-dependent patterns in short and irregularly sampled longitudinal datasets. This thesis reports the development of a statistical approach to support the identification of altered time-trajectories in such studies. The method’s wide applicability is subsequently demonstrated on two investigations covering the diversity of metabolic phenotyping data generation platforms. This thesis is a proof of concept for the characterisation of patient-specific inflammatory status in a clinical context and the identification of altered time-dependent patterns. Both analytical and statistical developments have been motivated by the needs of real world applications and provide a template for the characterisation and analysis of the molecular basis for treatment.

Statistical signal processing of noncircular quaternion random variables
Creators: name: Xiang, Min
Publisher: name: Imperial College London
Year: 2017

description: The focus of this thesis is on the development of theory and methods of statistical signal processing for noncircular quaternion random variables. Although it is straightforward to model three- and four-dimensional signals as real-valued trivariate and quadrivariate vectors, the division algebra of quaternions provides several crucial advantages. These include nonexistence of the gimbal lock associated with vector algebras and generic extensions of real and complex learning algorithms. However, traditional quaternion techniques are based on the assumption of circular (rotation-invariantly distributed) quaternion variables, a very limiting assumption for real-world applications. Only recently, advances in augmented quaternion statistics have revealed the suboptimality of such an assumption and have introduced the widely linear processing methodlogy, which is suitable for second-order noncircular signals. Abstract First, a simultaneous diagonalisation of the covariance matrix and the three complementary covariance matrices of noncircular quaternion variables is developed. This forms a basis for the proposed quaternion approximate uncorrelating transform (QAUT), which can be used to decorrelate noncircular quaternion variables, and offers both computational and practical advantages in many applications. Abstract Using the QAUT, the performance of existing minimum mean square error estimation techniques for noncircular quaternion signals is thoroughly explored. The performance advantage of widely linear estimation over strictly linear estimation is theoretically quantified, and the convergence performance of a class of quaternion adaptive filters is established in the mean and mean square sense. Abstract Several novel adaptive estimation techniques for noncircular quaternion signals are proposed. A novel quaternion least mean magnitude-phase adaptive filter is shown to outperform the quaternion least mean square filter in several practical scenarios. Computationally efficient algorithms are also introduced for the quaternion estimation framework, through a special decomposition of the mean square error. Finally, a class of quaternion multiple model adaptive estimation algorithms are proposed to effectively deal with model uncertainty in quaternion-valued state estimation.

description: The Brillouin zone of the clean Weyl semimetal contains points at which the density of states (DoS) vanishes. Previous work suggested that below a certain critical concentration of impurities this features is preserved including in the presence of disorder. This result got criticized for its neglect of rare disorder fluctuations which might bind quantum states and hence generate a finite DoS. We here show that in spite of their existence these states are so fragile that their contribution effectively vanishes when averaged over continuous disorder distributions. This means that the integrity of the nodal points remains protected for weak disorder.

Soundness and completeness of quantum root-mean-square errors

description: Defining and measuring the error of a measurement is one of the most fundamental activities in experimental science. However, quantum theory shows a peculiar difficulty in extending the classical notion of root-mean-square (rms) error to quantum measurements. A straightforward generalization based on the noise-operator was used to reformulate Heisenberg's uncertainty relation for the accuracy of simultaneous measurements to be universally valid and made the conventional formulation testable to observe its violation. Recently, its reliability was examined based on an anomaly that the error vanishes for some imprecise measurements, in which the meter does not commute with the measured observable. Here, we propose an improved definition for a quantum generalization of the classical rms error, which is state-dependent, operationally definable, and perfectly characterizes precise measurements. Moreover, it is shown that the new notion maintains the previously obtained universally valid uncertainty relations and their experimental confirmations without changing their forms and interpretations, in contrast to a prevailing view that a state-dependent formulation for measurement uncertainty relation is not tenable.

CO2 capture and photoconversion using multifunctional materials
Creators: name: Crake, Angus
Publisher: name: Imperial College London
Year: 2018

description: The sustainable production of energy is an exciting area for researchers requiring the development of improved technologies in both carbon dioxide (CO2) capture and CO2 utilization. This thesis presents the development and applications of bifunctional materials for CO2 capture by adsorption and utilization by photocatalytic conversion. Composite materials of solid sorbents and photocatalysts were designed primarily to increase CO2 abundance at the active sites and promote charge separation to aid photocatalytic activity. All materials were characterised using various structural, chemical and optoelectronic techniques. The materials were tested for CO2 capture and photoreduction using a gas-solid photoreactor. Composites of TiO2 and carbon nitride nanosheets (CNNS) were synthesised with control of the exposed TiO2 facets. When evaluated for CO2 adsorption and photocatalytic reduction the exposed TiO2 facets had significant influence in photocatalytic performance, the composite with more {001} facets exposed showed >10 fold higher activity than TiO2. TiO2 composites with metal organic frameworks (MOFs) were also designed; MOFs are an attractive class of materials for CO2 adsorption and their applications as photocatalysts are more recent. TiO2 and MOF (NH2-UiO-66) composites of various composition were evaluated for photocatalytic reduction of CO2 for the first time. The nanocomposites exhibited nanoparticle morphologies, maintained the CO2 adsorption capacity from the MOF component, and photocatalytically, the optimum composite was 1.5 times more active than TiO2 in conversion of CO2 to CO. Further enhancements in the TiO2/MOF composites were made by improving the TiO2-MOF interfaces by forming the MOF onto TiO2 nanofibers to promote more charge transfer. This resulted in a further 2.5-fold increase in photocatalytic reduction of CO2 to CO. A crucial phenomenon behind the improved photocatalytic activity of the composites was revealed by investigations of the charge dynamics, this showed successful formation of heterojunctions had facilitated interfacial charge transfer.

description: We present an analysis of low resolution infrared spectra for 20 brown dwarf candidates in the core of the $ρ$ Ophiuchi molecular cloud. Fifteen of the sources display absorption-line spectra characteristic of late-type stars. By comparing the depths of water vapor absorption bands in our candidate objects with a grid of M dwarf standards, we derive spectral types which are independent of reddening. Optical spectroscopy of one brown dwarf candidate confirms the spectral type derived from the water bands. Combining their spectral types with published near-infrared photometry, effective temperatures and bolometric stellar luminosities are derived enabling us to place our sample on the Hertzsprung-Russell diagram. We compare the positions of the brown dwarf candidates in this diagram with two sets of theoretical models in order to estimate their masses and ages. Considering uncertainties in placing the candidates in the H-R diagram, six objects consistently lie in the brown dwarf regime and another five objects lie in the transition region between stellar and substellar objects. The ages inferred for the sample are consistent with those derived for higher mass association members. Three of the newly identified brown dwarfs display infrared excesses at $λ$=2.2 $μ$m suggesting that young brown dwarfs can have active accretion disks. Comparing our mass estimates of the brown dwarf candidates with those derived from photometric data alone suggests that spectroscopy is an essential component of investigations of the mass functions of young clusters.

description: A nivel mundial hay preocupación por la intensificación del calentamiento global, al cual, entre muchos otros factores, contribuye las emisiones de Gases Efecto Invernadero (GEI), conocido como huella de carbono. Específicamente las actividades agrícolas aportan aproximadamente un 13,5% a las emisiones mundiales de GEI. En Colombia, la economía es fuertemente movida por el sector agrícola. Si bien, algunos investigadores del país han adelantado estudios sobr1e estimación y/o mitigación de huella de carbono en cultivos de productos específicos (arroz, caña de azúcar, flores, etc.), no se ha experimentado hasta el momento el uso de tecnologías de Inteligencia Artificial (IA) para apoyar los procesos que conlleva dicha estimación y/o mitigación. En este proyecto se aplicará la rama de la IA conocida como Planificación Automática (AP, por sus siglas en inglés) para crear planes de mitigación de huella de carbono generada por actividades agrícolas en Colombia. Para esto, es necesario parametrizar las actividades emisoras de GEI y las acciones asociadas a estrategias de mitigación de tal manera que se convierta en un sistema referente para cultivos en Colombia, agnóstico al producto agrícola.

The enantiophyllum clade of dioscorea in Africa: Systematics, distribution and conservation assessment
Creators: name: Omosowon, Sina
Publisher: name: Imperial College London
Year: 2018

description: Yams belong to the Dioscorea L. which is by far the largest genus in Dioscoreaceae with over 600 species and the fourth most important tuber crop in economic terms after potatoes, cassava and sweet potatoes. Yams are important food plants in many parts of the world, especially in West Africa, which produces about 93% of the World production. Dioscorea cayennensis and D. rotundata, which are collectively referred to as Guinea yams, are the most important cultivated yams native to Africa. Guinea yams belong to the Enantiophyllum clade which contains species with stems twining to the right. Despite the importance of Guinea yams, their relationship within the clade is poorly understood. In order trace the wild ancestors of the Guinea yams, a phylogenetic analysis based on sequence data from six plastid genes using 46 accessions of Dioscorea containing 12 of the 21 species of Enantiophyllum in Africa was carried out. Results showed that D. baya, D. praehensilis and D. abyssinica are the closest wild relatives of the Guinea yams. I also reconstructed ancestral morphological characters states for the African Dioscorea in the Enantiophyllum clade to understand how characters have evolved over time. It was revealed that morphological character diversity is a product of evolutionary changes. The current and potential impacts of climate change on the habitat distribution of Dioscorea in Africa were also evaluated to establish the actual and potential areas of occurrence for proper conservation planning. Dioscorea cotinifolia, D. praehensilis and D. schimperiana are shown to likely be affected by climate change. An IUCN Red List assessment was also performed to know the threat status and population trend of the wild African Enantiophyllum species of Dioscorea to identify species that needs immediate conservation management. All assessed species are classified as Least Concern (LC).

description: Near UV HST images of the remnant of SN 1885 (S And) in M31 show a 0"70 +- 0"05 diameter absorption disk silhouetted against M31's central bulge, at SN 1885's historically reported position. The disk's size corresponds to a linear diameter of 2.5 +- 0.4 pc at a distance of 725 +- 70 kpc, implying an average expansion velocity of 11000 +- 2000 km/s over 110 years. Low-dispersion FOS spectra over 3200-4800 A; reveal that the absorption arises principally from Ca II H & K (equivalent width ~215 A;) with weaker absorption features of Ca I 4227 A; and Fe I 3720 A;. The flux at Ca II line center indicates a foreground starlight fraction of 0.21, which places SNR 1885 some 64 pc to the near side of the midpoint of the M31 bulge, comparable to its projected 55 pc distance from the nucleus. The absorption line profiles suggest an approximately spherically symmetric, bell-shaped density distribution of supernova ejecta freely expanding at up to 13100 +- 1500 km/s. We estimate Ca I, Ca II, and Fe I masses of 2.9(+2.4,-0.6) x 10^-4 M_o, 0.005(+0.016,-0.002) M_o, and 0.013(+0.010,-0.005) M_o respectively. If the ionization state of iron is similar to the observed ionization state of calcium, M_CaII/M_CaI = 16(+42,-5), then the mass of Fe II is 0.21(+0.74,-0.08) M_o, consistent with that expected for either normal or subluminous SN Ia.

description: [fol. 108] A Montpellier ce 15 septembre 1778.

Monsieur,

Je vous fais parvenir le recueil de l’académie de Marseille au cas que vous ne l’ayez pas reçu, d’ailleurs vous pourrez garder cet exemplaire et je m’en procurerai un autre.
Vous y lirez certainement avec plaisir le discours de M. Liquier sur l’influence du commerce sur l’esprit et les mœurs des peuples ainsi que l’éloge de Mme de Sévigné finement touché par Mme la présidente de Brisson.
Je cherche en vain dans ce pays le Traité des semis et plantations de M. Duhamel dont j’aurais grand besoin. Si vous l’avez sous la main, vous m’obligerez de me le prêter pour peu de temps. Il est désolant de manquer de secours en ce genre. Il faudrait se ruiner pour se procurer tous les livres utiles. Il arrive d’ordinaire que lorsqu’un particulier achète un livre nouveau vingt autres l’achètent aussi, et pas un de se procurera le plus nécessaire.
Je vous embrasse de tout mon cœur. Il y a longtemps que je n’ai eu de vos nouvelles. Croyez qu’on ne peut être avec plus d’attachement,
Votre très humble et très obéissant serviteur

 Amoreux fils M.

CANASTERAS, CANASTOS Y PAISAJE EN EL MACIZO DE LOS PÁRAMOS DE MAMAPACHA Y BIJAGUAL EN EL SUR ORIENTE DE BOYACÁ
Creators: name: RUIZ BARAJAS, CAROL ANDREA
Publisher: name: Zenodo

description: Se presenta un recorrido para comprender el paisaje desde la perspectiva de las mujeres que, utilizando la gaita (Rhipidocladium geminatum), una planta que crece en los páramos de Mamapacha-Bijagual, tejen canastos en las montañas altoandinas de Boyacá, Colombia. El proceso de hacer canastos, conocido como "canastear", es una práctica común en las zonas rurales de Colombia. Sin embargo, canastear con la gaita implica un proceso particular que está intrínsecamente vinculado al entorno, incluyendo el páramo, las montañas y los caminos. De esta manera, se plantea el paisaje como un medio para el pensamiento antropológico, donde los objetos y la vida material se construyen a través de la interacción entre diferentes espacios, prácticas y tecnologías. El artículo explora la ecología de los materiales y resalta la importancia de incorporar la sutileza de la forma de vida orgánica para comprender las conexiones, lugares y memorias a través de las cuales se transforma la materia en un canasto. Se destacan los caminos trazados al seguir la invitación a explorar estas trayectorias y se propone un marco conceptual para comprender los "objetos que nacen en el campo", como resultado de atributos espaciales específicos y su relación con elementos vivos, naturalezas y tecnologías que fluyen a través del cuerpo y del habitar.

description: The distance to NGC 4725 has been derived from Cepheid variables, as part of the Hubble Space Telescope Key Project on the Extragalactic Distance Scale. Thirteen F555W (V) and four F814W (I) epochs of cosmic-ray-split Wide Field and Planetary Camera 2 observations were obtained. Twenty Cepheids were discovered, with periods ranging from 12 to 49 days. Adopting a Large Magellanic Cloud distance modulus and extinction of 18.50+/-0.10 mag and E(V-I)=0.13 mag, respectively, a true reddening-corrected distance modulus (based on an analysis employing the ALLFRAME software package) of 30.50 +/- 0.16 (random) +/- 0.17 (systematic) mag was determined for NGC 4725. The corresponding of distance of 12.6 +/- 1.0 (random) +/- 1.0 (systematic) Mpc is in excellent agreement with that found with an independent analysis based upon the DoPHOT photometry package. With a foreground reddening of only E(V-I)=0.02, the inferred intrinsic reddening of this field in NGC 4725, E(V-I)=0.19, makes it one of the most highly-reddened, encountered by the HST Key Project, to date.

Mean-field theory for superconductivity in twisted bilayer graphene

description: Recent experiments show how a bilayer graphene twisted around a certain magic angle becomes superconducting as it is doped into a region with approximate flat bands. We investigate the mean-field $s$-wave superconducting state in such a system and show how the state evolves as the twist angle is tuned, and as a function of the doping level. We argue that part of the experimental findings could well be understood to result from an attractive electron--electron interaction mediated by electron--phonon coupling, but the flat-band nature of the excitation spectrum makes also superconductivity quite unusual. For example, as the flat-band states are highly localized around certain spots in the structure, also the superconducting order parameter becomes strongly inhomogeneous.

The effect of supernova heating on cluster properties and constraints on galaxy formation models

description: Models of galaxy formation should be able to predict the properties of clusters of galaxies, in particular their gas fractions, metallicities, X-ray luminosity-temperature relation, temperature function and mass-deposition-rate function. Fitting these properties places important constaints on galaxy formation on all scales. By following gas processes in detail, our semi-analytic model (based on that of Nulsen & Fabian 1997) is the only such model able to predict all of the above cluster properties. We use realistic gas fractions and gas density profiles, and as required by observations we break the self-similarity of cluster structure by including supernova heating of intracluster gas, the amount of which is indicated by the observed metallicities. We also highlight the importance of the mass-deposition-rate function as an independent and very sensitive probe of cluster structure.

description: Understanding the high-order relationship between urban form and function is essential for modeling the underlying mechanisms of sustainable urban systems. Nevertheless, it is challenging to establish an accurate data representation for complex urban forms that are readily explicable in human terms. This study proposed the concept of core urban morphology representation and developed an explainable deep learning framework for explicably symbolizing complex urban forms into the novel representation, which we call CoMo. By interpretating the well-trained deep learning model with a stable weighted F1-score of 89.14%, CoMo presents a promising approach for revealing links between urban function and urban form in terms of core urban morphology representation. Using Boston as a study area, we analyzed the core urban forms at the individual-building, block, and neighborhood level that are important to corresponding urban functions. The residential core forms follow a gradual morphological pattern along the urban spine, which is consistent with a center-urban-suburban transition. Furthermore, we prove that urban morphology directly affects land use efficiency, which has a significantly strong correlation with the location (R2=0.721, p<0.001). Overall, CoMo can explicably symbolize urban forms, provide evidence for the classic urban location theory, and offer mechanistic insights for digital twins.

description: In this paper, we study the deflection of light by a class of phantom black hole and wormhole solutions in the weak limit approximation. More specifically, in the first part of this work, we study the deflection of light by Garfinkle-Horowitz-Ströminger black hole and Einstein-Maxwell anti-dilaton black hole using the optical geometry and the Gauss-Bonnet theorem. Our calculations show that gravitational lensing is affected by the phantom scalar field (phantom dilaton). In the second part of this work, we explore the deflection of light by a class of asymptotically flat phantom wormholes. In particular, we have used three types of wormholes: wormhole with a bounded/unbounded mass function, and a wormhole with a vanishing redshift function. We show that the particular choice of the shape function and mass function plays a crucial role in the final expression for the deflection angle of light. In the third part of the paper, we verify our findings with the help of standard geodesics equations. Finally, in the fourth part of this paper, we consider the problem for the observational relevance of our results studying the creation of the weak field Einstein rings.
