Human remains are frequently recovered fragmented from forensic contexts. Taphonomic factors and peri-mortem trauma can damage human remains recovered from clandestine graves. Therefore, an incomplete or broken skull can represent a challengeto identifying an individual, osteometric analysis, and trauma interpretation. A reconstructive approach is proposed to aid forensic experts in achieving all the information from human remains. This study proposes an innovative method that involves the use of reversible glue to connect the fragments. Non-permanent wax is used to reconstruct the missing parts and stabilize the skull. The reconstruction procedure is divided into three phases: cleaning, reassembling and remodelling. The reassembling is carried out with non-permanent reversible glue. Consequently, if the reconstructed remains do not have enough solidity to undergo a forensic examination, some of the missing anatomical parts can be replaced with reversible wax modelled on the missing bone’s shape. The method allows a more comprehensive examination of the whole skull structure for biological profiling of unknown individuals and a better analysis of trauma and injuries. Moreover, Computed Tomography (CT) and radiographic analysis can be better performed on areconstructed skull; the data obtained can also be a more appropriate background for unidentified persons’ facial approximations.

Abstract. Data capturing through either Lidar or photogrammetry, often results in incomplete and partial information related to a surface due to occlusion or inaccessibility of the clear object vision. In case of asymmetrical objects yet the reconstruction is unattainable by any means, meanwhile the approach for the development of the missing information could be done in cases of symmetrical objects. In this paper we have advised a semi-automatic approach for recreating missing or incomplete information from the partially captured data using space sub-division and 3D transformation. The study has been done on a 175 year-old building whose scanned information is available for only one side and captures a façade with four columns. The idea is to first extract the symmetrical parts through segmentation of different building parts. Then the columns with partial information have been oriented as per a reference plane based on the pose and centre computed from the horizontal parts. The instance is then used to fill in the lost information through duplication and transformation. This approach can be used to recreate structures with symmetrical elements, which are partially destroyed from withering, disaster, or any human intervention.

Recently, it has been demonstrated that chaotic signals can be used as carriers of information in communication systems. In this paper we propose a recovery method which, exploiting the determinism and redundancy of chaotic signals, allows us to reconstruct missing or distorted parts of a waveform that has been transmitted through a communication channel.

The monitoring of river water quality is important for human life and the health of the environment. However, water quality studies in many parts of the world, especially in developing countries, are restricted by the existence of missing data. In this study, the efficiency of the multilayer perceptron (MLP) and radial basis function (RBF) networks for recovering the missing values of 13 water quality parameters was examined based on data from five stations located along the Maroon River, Iran. The monthly values of other existing water quality parameters were used as input variables to the MLP and RBF models. According to the achieved results, the hardness missing values were estimated precisely by both the MLP and RBF networks, while the worst performance of the networks was found for the turbidity parameter. It was also found that the MLP models were superior to the RBF models to reconstruct water quality missing data.

Full textAbstract:
Background: Ameloblastic carcinoma is a rare and malignant odontogenic tumour possibly arising de-novo from pre-existing ameloblastoma. It is aggressive and locally destructive. Ameloblastoma is the most common benign odontogenic tumour of the mandible. It originates from the tooth-forming epithelium, where its aetiology remains unknown. Ameloblastoma usually grows slowly, is asymptomatic, and destroys the surrounding bone tissue. Malignant transformation of ameloblastomas may occur spontaneously. Resection is the primary therapy for ameloblastic carcinoma with extensive bone destruction. Mandibular resection causes instability due to the missing parts of bone, so reconstruction is needed. Purpose: This study will report on an individual case of ameloblastic carcinoma that underwent a bilateral ramus mandibulectomy with reconstruction using the plate technique. Case: Bilateral ramus mandibulectomy with plate and reconstruction in an ameloblastic carcinoma patient. Case Management: Two months after surgery, the patient could open her mouth functionally and aesthetically. Conclusion: Plate reconstruction is an option for reconstructing bilateral ramus mandibulectomy of a large ameloblastic carcinoma of the mandible.

Abstract Manufacturing replicas for replacing missing or defective body parts also incorporates 3D technology, including scanning, image processing and printing. In the case of the ears, both aesthetics and functionality play a significant role. Based on these techniques, outer ear replicas were produced using 3D scans of human skulls in a rapid prototyping procedure for actual patients. Hand-held scanners delivered accurate images for post-processing of the mesh and for printing in a cost- and time efficient way. Use cases of patients demonstrate applicability, allowing the technology to be available also for the general population in the future.

Full textAbstract:
Computed tomography is a versatile imaging technique used to enable seeing internal structures of objects without opening or destroying them. This is possible through a process called tomographic reconstruction, which reconstructs images from projections of the object that are obtained by penetrating the object with beams of radiation, such as X-rays, from different angles. These projection data are often limited to low-resolution data in terms of projection angles. These limited or subsampled data make it difficult to obtain high-quality reconstruction results. Hence, upsampling projection data is necessary. In this paper, we propose a sinogram upsampling method via the sub-Riemannian diffusion process. We first lift the data into a feature space, and we fill in the missing angle parts by propagating information from the observed data to the missing parts. We observe that the sinogram with limited angle data has high directional dependency, and based on this observation, we suggest an adaptive weighting scheme to keep information propagating toward the missing regions. This adaptive weighting allows for diffusing toward the desired directions. The experimental results show the effectiveness of the proposed method in some scenarios regarding inpainting fine details, when compared to the existing model-based methods, such as Plug-and-Play and total generalized variation.

Full textAbstract:
Those who work with the papyri or stone inscriptions from the ancient world frequently are faced with incomplete texts. Papyrologists or epigraphers will attempt to fill in the missing parts of the text, relying on their knowledge of what similar documents say. Sometimes a later find will provide a missing piece. Experience with such finds has been that an expert reconstruction normally will get the basic sense of the document right, but rarely gets the exact wording right when anything more than a few letters needs to be filled in.

As in 2009 the Neues Museum (“New Museum”) in Berlin was reopened after restoration, the long awaited moment triggered most various reactions between praise and criticism. The core of all debates was the treatment of loss and the reconstruction (or non-reconstruction) of the missing architectonical parts such as the staircase (Trepenhalle). Being one of the most debated contemporary conservation projects, we ask ourselves how does the restoration of the Neues Museum work in the eyes of the beholder and what could be the judgment behind the rejection or approval?

Abstract 3D scanning is widely used in multiple applications to obtain high precision / non-destructive documentation of real-life objects, which is especially important in Cultural Heritage (CH) preservation. However, some issues (in particular missing parts which are commonly known as “holes”) affect the accuracy of the obtained 3D model after the scanning procedure and requires time-consuming post-processing procedures, which include manual editing by highly-trained personnel. In this article an automatic method to reconstruct the obtained surface of 3D models is proposed, improving previously obtained results for high-density point clouds.

Cinq crises majeures ont affectées la biodiversité et les activités humaines mènent à une sixième. La disparité, visant à quantifier la diversité morphologique, est une approche pertinente pour comparer ces crises. La disparité a toutefois été rarement appliquée à la biologie de la conservation. Nous étudions, ici, l’impact sur la disparité des ailes d’Odonata (1) de l’artificialisation de l’occupation des sols et (2) de l’extinction de masse Permo-Triassique. Pour quantifier la morphologie alaire, nous avons élaboré un patron de base d’homologies de nervation alaire applicable aux espèces actuelles et fossiles. Nous avons, ensuite, utilisé la morphométrie géométrique et élaboré un set de landmarks et de semi-landmarks optimale. L’impact de l’artificialisation a été étudié sur des sites en Ile-de-France. L’artificialisation et la perte d’espèces n’a pas d’impact significatif sur la disparité, ce qui supporte un scénario d’extinction non-sélective sur la morphologie. Rien n’indique que la morphologie alaire puisse aider à identifier des espèces spécialistes ou généralistes. Aucunes différences significatives n’ont été observées entre la disparité et la diversité du Permien et du Trias. Des morphologies extrêmes perdues durant le Permien ont pu être compensées par de nouvelles morphologies extrêmes durant le Trias. Étant donné la résolution temporelle, les effets de la perte et récupération d’espèces ne peuvent être distingués. Les crises actuelles pourraient être comparables, dans leurs effets, aux extinctions de masses passées. Cependant, les données sur les actuelles devraient être élargies et la résolution de l’échantillonnage fossile affinéeFive major crises have affected biodiversity and human activities are leading to a sixth one. Disparity, aiming at quantifying morphological diversity, might be a relevant approach to compare these crises. Disparity has, however, rarely been applied in conservation biology. Here we investigated the impact on Odonata wingdisparity (1) of land cover artificialization and (2) of the Permo-Triassic mass extinction. To quantify wing morphology, we assessed a basic pattern of wing venation homologies applicable to extant and fossil species. We then used a morphometric geometric approach and elaborated an optimal set of landmarks and sliding semi-landmarks. Impact of artificialization has been investigated on sites in Ile-de-France. Artificialization and loss of species do not significantly impact disparity. This support a scenario of a non-morphologically selective extinction. We did not found evidence that wing morphology might help recognition of specialised or generalist species. No significant differences between disparity and diversity of the Permian and the Triassic were observed. Extreme morphologies lost in the Permian may have been compensated with new extreme morphologies during the Triassic. Given the temporal resolution, effects of species loss and recovery cannot be distinguished. Current crises could be comparable in their effects to past mass extinction. However, data on extant should be broadened to all the species monitored worldwide and resolution of fossil sampling refined

Full textAbstract:
Information Hunters examines the unprecedented American effort to acquire foreign publications and information in World War II Europe. An unlikely band of librarians, scholars, soldiers, and spies went to Europe to collect books and documents to aid the Allies’ cause. They traveled to neutral cities to find enemy publications for intelligence analysis and followed advancing armies to capture records in a massive program of confiscation. After the war, they seized Nazi works from bookstores and schools and gathered countless looted Jewish books. Improvising library techniques in wartime conditions, they contributed to Allied intelligence, preserved endangered books, engaged in restitution, and participated in the denazification of book collections. Information Hunters explores what collecting meant to the men and women who embarked on these missions and how the challenges of a total war led to an intense focus on books and documents. It uncovers the worlds of collecting, in spy-ridden Stockholm and Lisbon, in liberated Paris and devastated Berlin, and in German caves and mineshafts. The wartime collecting missions had lasting effects. They intensified the relationship between libraries and academic institutions, on the one hand, and the government and military, on the other. Book and document acquisition became part of the apparatus of national security, military planning, and postwar reconstruction. These efforts also spurred the development of information science and boosted research libraries’ ambitions to be great national repositories for research and the dissemination of knowledge that would support American global leadership, politically and intellectually.

Full textAbstract:
The original endocast of A.L. 444-2 consisted of a single plastic cast, colored to show the original fragments (light brown) and the reconstructed missing parts (black). This we label the Rak-Kimbel endocast, which was based on the reconstruction of cranial and facial fragments. Because distortion was severe enough to interfere with morphological description and measurements, and especially the assessment of endocranial capacity, a plaster endocast was received from Yoel Rak in 1998 for purposes of modification. This newer plaster endocast formed the basis for the original endocast reconstruction done by R.L.H., who based the reconstruction on the less distorted side (left) and then doubled its water-displaced volume to achieve the final endocranial volume. As will become clear in our descriptions, this first method required several additions and subtractions to compensate for missing portions, for flash lines left from the casting process, and for distortion remaining in the reconstruction. We concluded that a more accurate reconstruction would result if the portions of the original endocast were separated from reconstructed elements and approximated on a plasticene “core” so that distortion could be effectively eliminated. The second method, which was accomplished mostly by M.S.Y. with minimal guidance from R.L.H., permitted a range of possible reconstructions of the actual brain endocast pieces and provided a range of endocast volumes. This reconstruction methodology, referred to as the “dissection method,” eliminated most of the distortion and obviated the need to correct for flash lines. Although both methods provide a final endocranial capacity very close to what must have been the actual living brain volume of A.L. 444-2, we consider the dissection method to be the more accurate one. Distortion of the endocranial cast mirrors that of the cranium. While the right parietotemporal area appears to be depressed, the left parietotemporal area shows signs of bulging in compensation. In addition, due to a gap that runs anteroposteriorly along the left temporal lobe, there is an artificial increase in the distance between the base of the endocast and its apex of about 3–8 mm on the left side.

The A.L. 444-2 skull was found on 26 February 1992, during a strategic paleontological survey of Kada Hadar Member sediments that are stratigraphically situated between BKT-1 and BKT-2 tephras, on the eastern edge of the Awash River’s Kada Hadar tributary. Yoel Rak discovered two fragments of hominin occipital bone (A.L. 444-1) at the base of a steep hill composed of Kada Hadar Member silts and clays capped by a weathered sandstone remnant. Subsequent examination of the upslope surface revealed additional hominin skull fragments (the temporal bones and maxillae) clustered together and partially exposed in a narrow gully that dissected the face of the hill. During the next seven days, probing and dry sieving of the gully infill and hillside colluvium over a 77 m2 area led to the recovery of fragments representing about 75%–80% of a single hominin skull. It was immediately apparent that the upslope finds duplicated the anatomical parts represented by the two A.L. 444-1 occipital fragments and therefore constituted a second hominin individual, cataloged as A.L. 444-2. In addition, the lambdoidal suture of the A.L. 444-1 occipital is completely unfused, suggesting subadult status, whereas fused cranial sutures and extreme dental occlusal wear indicate an advanced ontogenetic age for A.L. 444-2. In February–March 1993 the A.L. 444 hillside was excavated in an effort to locate missing parts of the A.L. 444-2 skull and to determine its precise stratigraphic provenance. No further remains of the hominin skull were encountered in situ, but a complete viverrid cranium and indeterminate fragments of large mammal bone with preservation and patina (mottled dark gray, white, and yellowish gray) identical to those of the hominin were excavated in an unstratified, cemented carbonate silt that exactly matches the matrix adhering to A.L. 444-2. We are confident that the hominin skull is from this sedimentary horizon. It is approximately 10.5 m stratigraphically below the BKT-2 tephra, which outcrops in the immediate vicinity of A.L. 444 Single-crystal laser fusion (SCLF) 40Ar/39Ar ages for BKT-2 and Kada Hadar Tuff (KHT) bracket the geological age of A.L. 444-2 between 2.94 and 3.18 Myr (Kimbel et al., 1994; Walter, 1994; Semaw et al., 1997).

One of the first fields for Methodist Episcopal Church missions was New Orleans and the lower Mississippi River valley, and it proved to be fertile soil for the rise of vibrant congregations of aspiring African Americans. Records for this area give a better portrait of the Black members than can be found elsewhere, thanks in large part to Octavia Rogers Albert’s House of Bondage. Chapter 3 discusses how white leaders like Joseph Hartzell and Black leaders like Hiram Revels hoped to cultivate relations with southern whites that would pave the way toward social acceptance. That included resisting the movement toward separate conferences for the races. Freed slaves and their white allies faced instead a violent backlash that caused the Exoduster movement toward Kansas.

Chapter 9 offers a detailed analysis of Philebus 42c–47d.

This chapter (inter alia) sketches Socrates’ argument concerning the neutral state, explores the view that he wishes to attribute to the ‘Stroppies,’ explains how he employs their arguments and methodology, provides a reconstruction of an important missing part of their argument concerning the view that pleasure doesn’t really exist, explains how Socrates’ own account contrasts with that of the Stroppies, and explores the notions of false pleasure/pain in play in this part of the Philebus.

ANALYSES CONCERNING PHAENOMENA OF DESIRE IN HUSSERL’S THOUGHT Starting from the analysis of a large group of long unpublished manuscripts, known as Studies on the Structure of Consciousness and recently published as volume XLIII of the complete works, this contribution aims at reconstructing some central elements in Husserlian analysis of the phenomena of the sphere of desire. These phenomena are an excellent example of the interweaving that concretely constitutes the life of consciousness: they are in fact distinct from the acts of feeling and volition, while maintaining structural connections with them. In particular, they are an expression of that peculiar intentional mode that Husserl defines as “taking part in things”, thanks to which the subject is involved in the dynamics of the world. In the dimension of desire, Husserl finds three distinct phenomena: simple whishing (Wünschen), desire in the strict sense (Begehren) and the drive feeling (Triebgefühl). All of them show, each in its own way, a common character, namely missing (vermissen), which reveals a lack or a deficiency in the emotional life of consciousness. In simply whishing, the subject remains in a feeling of lack, missing something not yet real and desiring something in the sense of simply wanting, without actively striving for it. On the contrary, desire in the strict sense implies that the lacking object is given as something that calls us strongly, driving us toward possession and appropriation. Finally, in the case of the drive feeling, there is a lack understood as a restlessness that gives rise to a drive movement or action, in which the tension is discharged.

Abstract The amalgamation of the Ethiopian and AME churches culminated a remarkable historical convergence between black Christians at opposite corners of the Atlantic. For African American Christians, the opening of the African mission field helped salve the pain of the past: slavery, for all its horror and brutality, had been progressive, a part of God’s unfolding plan for the redemption of Africa. For Mangena Mokone and his comrades, the prospect was equally invigorating. Seen through the prism of black America, their humble rebellions in places like Marabastad and the Waterberg resolved themselves into the stuff of prophecy. As Jacobus Xaba put it, “The prophecy predicted by the Psalmist, 68, approaches its perfection.” Ultimately, however, the handful of leaders gathered around Mokone neither encompassed African Methodism nor exhausted its meanings. If the South African church had remained the province of a handful of dissident clerics, it would scarcely have generated the enthusiasm it did or struck such fear into the hearts of colonial officials. In the decade and a half after its founding—a period that encompassed the South African War, imperial reconstruction, and the creation of the Union of South Africa—African Methodism exploded across the southern African subcontinent.

Abstract The attentive reader will have noticed that none of the arguments against the second premise, that empirical equivalence entails underdetermination, has managed to survive the critical scrutiny of chapter 6. To my knowledge, there are no persuasive refutations of this thesis. Of course, the failure to show that a thesis is false doesn’t imply that it’s true. This chapter begins with an examination of antirealist attempts to convince us to adopt the second premise.. Actually, to speak of”attempts” in the plural is already to be overly sanguine about the prospects for success. Combing the literature of antirealism turns up only two passages, both by van Fraassen, that might be construed as arguments for the second premise, and the second of these passages merely supplies a part of the analysis that’s missing from the first. So there’s really only one argument for the second premise on the table. Moreover, this one and only argument has several strikes against it before the analysis even begins. For one thing, both passages have the character of passing remarks; to find a coherent argument in them requires a fair amount of speculative reconstruction. For another, there are portions of the reconstructed argument that are inconsistent with some of van Fraassen’s other published opinions. Finally, there are still other portions of van Fraassen’s body of work which suggest that the second of the two cited passages shouldn’t even be construed as an attempt at rational persuasion. To refer as I do to “van Fraassen’s argument” is to take considerable liberties.

Wars of liberation brought together the ‘Second World’ with Africa and Asia in the postwar period. This chapter traces how both sides recognized commonalities of purpose: how the memory of struggle of the Soviet Red Army, the Yugoslav partisans or even the nationalist Polish Home Army during the Second World War was integrated into a professed commitment to defend a hard-won anti-fascist and anti-imperialist world. Weapons were provided by Eastern Europeans as expressions of solidarity,and later as business opportunities; training camps for liberation movements were established across the region and beyond; its militaries took part in peace missions (e.g. following Vietnam), engaged in reconstruction efforts (e.g. Algeria) or resettled populations after other conflicts (e.g. Korea). Third World leaders sought to represent their own struggles as models to be supported by their Eastern European partners, whilst also identifying with the manner in which Europeans had overcome conflict on their own continent. Nevertheless, violence which had once been accepted as legitimate by a generation that had lived through the Second World War was more and more associated with the supposedly excessive demands of liberation movements, or with the threatening terrorism of Islamic groups. By the last decades of the Cold War, Eastern European Communist states were increasingly divided on these questions—whilst the Soviets and the GDR still saw revolutionary violence as acceptable in some circumstances, other elites preferred to propagate peace, solutions based in international law, and trade.

Abstract Uncertain factors such as environmental noise and light source fluctuation will cause the loss of important features of the detection object, which will interfere with the detection and reconstruction accuracy. Therefore, accurate extraction of groove information is the key to ensure the quality of subsequent processes when detection technology is applied to steel structure grooves in ships, buildings, transportation and other fields. This paper designs a complex shaped detection and reconstruction algorithm based on linear structured light. This algorithm performs the visually assisted localization of the ROI area of the welding groove in a complex environment, and completes the extraction of the characteristic area of the welding groove and the interpolation of missing parts based on the slope method. According to the obtained information, the digital modeling analysis of each groove section feature is carried out, and the 3D model is reconstructed based on the feature information fitting. The extraction of geometric characteristics of single V-groove and the reconstruction of the 3D model are realized, and the effectiveness of the extracted geometric characteristics is verified. On this basis, the subsequent welding is completed well, which verifies that the algorithm can effectively reduce the influence of the lack of groove characteristics caused by uncertain factors.

The Municipal Archaeological Museum of Burriana began the virtualization of parts and elements of cultural heritage and historic buildings in the early years of this century. Tangible results showed up from 2010. Regarding to archaeological artifacts two basic lines of action have been explored; on the one hand, literal documentation of pieces for later exhibition in augmented reality displays. Secondly, the research in the virtual recreation of missing elements or in the reconstruction of pieces. About the issue of cultural heritage we are currently in the documentation of buildings and archaeological excavations for augmented reality or didactic stage. We will also briefly discuss the prospects in the current virtualization works.

In ASME 2021 Fluids Engineering Division Summer Meeting. American Society of Mechanical Engineers, 2021. http://dx.doi.org/10.1115/fedsm2021-65861.
Full textAbstract:
Abstract Digital inline holography (DIH), as a three-dimensional (3D) measurement technique, is widely used in characterizations of the particles, droplets or bubbles under different multi-phase flow circumstances. By analyzing the phase information carried by the interference pattern, the reconstruction of shape and the location of a test target is then achieved. However, such reconstruction mechanism produces different levels of uncertainty between the in-plane (the plane parallel to the hologram plane) direction and out-of-plane (the plane normal to the hologram plane) direction, and the uncertainty of the latter is larger than the former. Also, the reconstruction algorithm fails when the interference patterns of some sections of the target are overlapped on the hologram since the overlapped patterns are merged into a pure shadow which doesn’t carry any phase information. This paper tested a method, the Multi-view Digital Inline Holography (MvDIH), that combines the holograms recorded from multiple views to overcome the addressed defects of the single view DIH. This technique uses the similar setup as the DIH but applies a different post-process method to implement the reconstruction. As the DIH is applied to each view, one can not only acquire the cross-section of the target in the hologram plane but also the outline of such cross-section in the space. Then, two reconstruction methods with different ideologies are developed as, the one based on the outline and the one based on the cross-section. A post-process algorithm is developed to realize these two reconstruction methods with the holograms recorded from different views. To evaluate the performance of the Multi-view DIH, a test model which imitates the droplet and liquid ligament structure is 3D printed and measured by the proposed method. The results demonstrate that, with only three view, both method provides limited reconstruction result. When comparing to the true test model, for the outline based method, some parts of the reconstructed model are missing and some details are merged into one piece with simple geometry. Yet, for the cross-section based method, the reconstructed model contains redundant parts which also make such result unsatisfied. As the used holograms are increased to six views, the reconstructed result for cross-section based method is approaching to the true model, but still some sections are reconstructed with certain level of ambiguity.

Full textAbstract:
Within the field of Cultural Heritage, image inpainting is a conservation process that fills in missing or damaged parts of an artwork to present a complete image. Multi-modal diffusion models have brought photo-realistic results on image inpainting where content can be generated by using descriptive text prompts. However, these models fail to produce content consistent with a particular painter’s artistic style and period, being unsuitable for the reconstruction of fine arts and requiring laborious expert judgement. Moreover, generative models produce many plausible outputs for a given prompt. This work presents a methodology to improve the inpainting of fine art by automating the selection process of inpainted candidates. We propose a discriminator model that processes the output of inpainting models and assigns a probability that indicates the likelihood that the restored image belongs to a certain painter.

In 3rd International Conference on Community Engagement and Education for Sustainable Development. AIJR Publisher, 2023. http://dx.doi.org/10.21467/proceedings.151.k4.
Full textAbstract:
Typhoon Morakot produced more than 2000 mm of rainfall in two days during August 2009, causing catastrophic damage to parts of southern Taiwan. In the aftermath, 673 people died; 26 went missing; and 1,766 houses were destroyed. To facilitate recovery and reconstruction after the typhoon, the state approved a Special Act of Reconstruction for delimiting specific disaster regions and imposing forced relocation of villagers. A total of 3,096 households, mostly indigenous groups, were relocated to 35 permanent housing units from mountains to lowlands. Without any farmlands, villagers struggled to maintain their livelihoods. In 2020, indigenous villagers protested against the county government for its intention to demolish illegal structures, built by villagers as tourism-related businesses. This advocacy was supported and followed by several university faculty members and NGOs through numerous actions, including organizing protests, filing petitions, and conducting workshops to advocate indigenous human rights. In addition, through university-community collaborations, several “soft actions” were emerged, such as building genealogy and curating settlement history and pictures in local museums, for more community involvement and empowerment. Above all, these advocacy and community actions reflected Sustainable Developments Goals (SDGs) in “climate actions” and “reduced inequalities.” Moreover, through reflections of these actions, community post-disaster resilience may be more about resistance than adaptation. In the future, university scholars and students will continue to work with indigenous communities for advocating indigenous human rights in the era of climate change.

Visual defect detection is a key technology in modern industrial manufacturing systems. There are many possible appearances of product defects, including distortions in color, shape, contamination, missing or superfluous parts. For the detection of those, besides traditional image processing techniques, convolutional neural networks based methods have also appeared to avoid the usage of hand-crafted features and to build more efficient detection mechanisms. In our article we deal with autoencoder convolutional networks (AEs) which do not require examples of defects for training. Unfortunately, the manual and/or trial-and-error design of AEs is still required to achieve good performance, since there are many unknown parameters of AEs which can greatly influence the detection abilities. For our study we have chosen a well performing AE known as structural similarity AE (SSIM-AE), where the loss function and the comparison of the output with the input is implemented via the SSIM instead of the often used L1 or L2 norms. Investigating the performance of SSIM-AE on different data-sets, we found that its performance can be improved with modified convolutional structures without modifying the size of latent space. We also show that finding a model with low reconstruction error during training does not mean good detection abilities and denoising AEs can increase efficiency.

The search for short-lived particles is an important part of physics research in experiments withrelativistic heavy ions. To find, select and study the properties of such short-lived particles in real timein the CBM experiment (FAIR/GSI, Germany), we have developed a package of algorithms, KFParticle Finder, which contains a search for more than 150 decay channels. The decays of short-livedcharged particles, when one of the daughter particles is neutral and cannot be registered in the detectorsystem, are also of great physics interest. To find and study such decays, we have extended the KFParticle Finder package by implementing the missing mass method, which is based on theconservation of energy and momentum laws.The method was studied in detail on simulated data of the CBM experiment, showing high efficiencywith a large signal-to-background ratio, as well as high significance. As part of the FAIR Phase-0program, the KF Particle Finder package of algorithms has been adapted for online and offlineprocessing in the STAR experiment (BNL, USA).Here we describe and discuss in detail the missing mass method for finding and analyzing short-livedparticles. The features of the application of the method to both simulated data in the CBM experimentand in the STAR experiment as part of real-time express data processing, as well as the results of thereal-time reconstruction of short-lived particle decays in the BES-II environment of the STARexperiment, are given.

Full textAbstract:
Abstract. Small sounding balloons are a fast and cost-effective transport system to lift up scientific payloads up to stratospheric burst altitudes below 40 kilometres; during ascent and descent phase dedicated instruments may be operated to monitor atmospheric parameters and optical payloads may be used for remote observation. This work will focus on the reconstruction of the trajectory of the ascent phase, which is the longest and dynamically less perturbed part of the flight; in this section the dynamics of the flight system is determined by the lift of the balloon guiding the vertical motion and the local winds controlling the horizontal motion. The presented reconstruction algorithm is based on a linear quadratic estimation predictor corrector using the standard equations of motions in ECEF system to propagate the simulation and the measurement of the on-board sensors (triaxial accelerometer, GPS, pressure and temperature sensors) to correct the estimation and reduce the uncertainty in the reconstruction, which is mainly related to the value of balloon canopy drag coefficient Cd, the lifting gas volume and local wind perturbations. Two different balloon flights, both launched within a joint effort between teams by University of Padova and University of Pisa, are considered: one conducted during daytime, the other in night time. The different environmental conditions and in particular the different temperature evolution within the lifting balloon in the day flight due to Sun heating provide a good proving ground to investigate sensitivity of algorithm to environmental conditions. The prediction of flight dynamic models implementing horizontal and vertical equations of motion are compared with real mission data acquired by on board systems, highlighting the influence of local perturbations on the foreseen ascent trajectory.

Full textAbstract:
The Hrvatski Leskovac - Karlovac section is located on the M202 Zagreb GK - Rijeka railway line, which is part of the Mediterranean corridor of the EU core network. The section is currently a single-track line, and represents a bottleneck in terms of infrastructure capacity. The project envisages the reconstruction of the existing and construction of the second track with the reconstruction of the existing stations in order to meet the conditions of interoperability, the transformation of individual stations into stops, and the reconstruction of existing stops. Some of the existing railway-road crossings will be delevelled by constructing crossroads in two levels (underpasses and overpasses), some will be eliminated with the construction of connection roads and some will be reconstructed. The project is currently in the contracting phase of works and supervisions. In the period from 2017 until today, the Ministry of Environmental Protection and Energy (MZOE) Decision was published on the Environmental Impact Study, the Location Permit was obtained, and the Feasibility Study was completed and approved by the JASPERS Mission in the Republic of Croatia.

Full textAbstract:
The problem which is addressed in this paper refers to the discussion, how complex should be the features extracted from the 3D mesh of a target, in order to get a stable and accurate relative pose estimation with monocular cameras during an On-Orbit Servicing (OOS) mission scenario.The process of the key points extraction from 3D models is very challenging task because of following issues. A) There is no strict definition how the interesting key features should be defined. In most cases it is dependent on the features, which are going to be detected on the space object. Very common features are corners or lines of the spacecraft, which can be detected from the visual data for further matching. Considering these parts, we have to build a 3D key features of the target accordingly. B) The up-to-date target model may be only available during the mission, e.g. reconstruction during inspection phase. When we are still on the ground, we can only have an approximate 3D model of the target. Then the question arises – how do we define the model key points on the ground before the OOS mission takes place, if these points could be no more exist on the real space object? It should be defined - if an on-board algorithm is needed or the data should be processed on the ground. C) The limited computing power on board. The processing time for the model key extraction on the ground is not a problem. The challenge is feature processing tasks in space using an On-Board Computer (OBC). Dependent on the platform of OBC, the extraction of 2D image points with it following matching should be fast enough to process live images. We propose two models: the first model contains manually extracted key points; the second one has key points extracted using HarrisKeypoint3D technique from PCL Library. The automatic process of extracting 3D key points with HarrisKeypoint3D function can be used with different 3D meshes of the space object. Thus, can be applied in different OOS missions. We are going to present the results of relative pose estimation using two different models of the target mockup located at European Proximity Operations Simulator (EPOS), German Aerospace Center. Some camera images and ground truth are collected for pose estimation tests also from EPOS facility.
