Abstract Failure analysis is an investigative process in which the visual observations of features present on a failed component and the surrounding environment are essential in determining the root cause of a failure. This article reviews the basic photographic principles and techniques that are applied to failure analysis, both in the field and in the laboratory. It discusses the processes involved in visual examination, field photographic documentation, and laboratory photographic documentation of failed components. The article describes the operating principles of each part of a professional digital camera. It covers basic photographic principles and manipulation of settings that assist in producing high-quality images. The need for accurate photographic documentation in failure analysis is also presented.

We study two approaches for predicting an appropriate pose for a robot to take part in group formations typical of social human conversations subject to the physical layout of the surrounding environment. One method is model-based and explicitly encodes key geometric aspects of conversational formations. The other method is data-driven. It implicitly models key properties of spatial arrangements using graph neural networks and an adversarial training regimen. We evaluate the proposed approaches through quantitative metrics designed for this problem domain and via a human experiment. Our results suggest that the proposed methods are effective at reasoning about the environment layout and conversational group formations. They can also be used repeatedly to simulate conversational spatial arrangements despite being designed to output a single pose at a time. However, the methods showed different strengths. For example, the geometric approach was more successful at avoiding poses generated in nonfree areas of the environment, but the data-driven method was better at capturing the variability of conversational spatial formations. We discuss ways to address open challenges for the pose generation problem and other interesting avenues for future work.

Abstract Background This research paper contributes to presenting a proposed framework for the formal and structural specifications of parametric digital architecture in order to increase knowledge and know-how in this field closely to specialists and those interested in it through the research methodology, which is divided first into the theoretical background to include a presentation of the definition of digital architecture and the most important pioneers of digital architecture, digital building materials and construction mechanisms parametric digital and what are the most important computer software used in parametric digital architecture in terms of design and construction implementation and identifying the most important digital specifications and characteristics that were mentioned in previous studies in this field and what are the unconventional digital esthetic values, then comes the role of the applied study in formulating a comprehensive matrix of parametric design modern and its impact on the development of traditional architectural models in digital architecture. Results The research study found that both (unrealistic shape) and (typical interaction) ranked first with the highest percentage reaching 100% in all study cases. The ratio of the volume of each to the total volume of all elements of morphological characteristics and non-traditional esthetic values was 8%, the most important characteristic of buildings in parametric digital architecture, in most of them, is the lack of realism to a very significant degree, and we always find a clear increase in the interaction, vitality and dynamism of buildings with the surrounding environment. Conclusions The most important characteristic of buildings in parametric digital architecture, in most of them, is the lack of realism to a very significant degree, and we always find a clear increase in the interaction, vitality and dynamism of buildings with the surrounding environment. While we conclude that the least characteristic of the parametric digital buildings is the simulation of nature or the tendency to everything that is traditional, as well it is often inclined to everything strange and unfamiliar.

The term microbiome means not only a complex ecosystem of microbial species that colonize our body but also their genome and the surrounding environment in which they live. Recent studies support the existence of a gut-retina axis involved in the pathogenesis of several chronic progressive ocular diseases, including age-related macular disorders. This review aims to underline the importance of the gut microbiome in relation to ocular health. After briefly introducing the characteristics of the gut microbiome in terms of composition and functions, the role of gut microbiome dysbiosis, in the development or progression of retinal diseases, is highlighted, focusing on the relationship between gut microbiome composition and retinal health based on the recently investigated gut-retina axis.

Abstract Since being rediscovered as an emerging 2D material, BP with extraordinary energy structure and unusually strong interlayer interactions offer new opportunities for optoelectronics and photonics. However, due to the thin atomic body and the ease of degradation with water and oxides, BP is highly sensitive to the surrounding environment. Therefore, high-quality engineering of interfaces and surfaces plays an essential role in BP-based applications. In this review, begun with a review of properties of BP, different strategies of interface and surfaces engineering for high ON-OFF ratio, enhanced optical absorption, and fast optical response are reviewed and highlighted, and recent state-of-the-art advances on optoelectronic and photonic devices are demonstrated. Finally, the opportunities and challenges are outlooked for future BP-related research.

Bauxite waste sludge is quite dangerous when polluted into the surrounding environment. The number is increasing with the higher mining production. The utilization is still not maximized hence it is unbalanced to the increasing number, and it is necessary to use on a large scale. Sub-grade soil could use a lot of bauxite waste sludge but in reality, this waste is unsafe to use and its characteristics are mud the requirements of bearing capacity according to the AASHTO and USCS Classification unfulfilled. This study aims to determine the effect of the use of probiotic bacteria in bauxite waste on its physical characteristics and pH value. This experimental research method develops test objects according to ASTM standards with the same weight of bauxite waste and variations in the number of probiotic bacteria, namely 25 ml, 50 ml, 75 ml, and 100 ml and the incubation time of bacteria is 7 days, 14 days, 21 days, 28 days, 35 days, and 42 days. The results showed that the test specimens with more bacteria and longer incubation times resulted in lower pH values and physical characteristics that fulfilled the requirements for sub-grade soil.
