Authors: Jamet Maxime , Ballas Gregory , Soliva Roger , Gerbeaud Olivier , Lefebvre Thierry , Leredde Christine , Loggia Didier
Published: February 2024

Abstract. This study delves into the characterization of a complex reservoir, the Tchirezrine II sandstone unit in North Niger, crucial for potential Uranium In Situ Recovery (ISR) in a naturally fractured and faulted context. Employing a multifaceted approach, including well log data, optical borehole imagery, and hydrogeological tests, alongside satellite-based lineament analysis, this study provides a comprehensive understanding of the structures and its impact on fluid flow. Lineament analysis reveals scale-dependent patterns, consistent with spatially homogeneous joint networks restricted to mechanical units, as well as nearly scale-invariant patterns, better corresponding to spatially heterogeneous fault networks. Various deformation structures are detected from borehole imagery, including Mode I fractures, cataclastic deformation bands, and brecciated-cataclastic fault cores. The Tchirezrine II reservoir displays heterogeneous porosity and permeability related to its fluviatile sedimentary context. These data differ from traditional porosity-permeability relationship obtained in sandstone reservoir matrix but are instead consistent with Nelson’s classification, emphasizing the impact of deformation structures on such petrophysical properties. Hydrological tests have been implemented into a zone of E-W trending deformation structures, revealing a strong permeability anisotropy of this heterogeneity. This strong E-W anisotropy is consistent with the presence of the observed E-W structures, i.e. with a drain behaviour of Mode I open fractures and a sealing behaviour of both cataclastic bands and fault rocks. Considering implications for ISR mining, this study allows discussing the interplay between fractures, faults, and fluid flow properties. It suggests that a well pattern perpendicular to the main permeability orientation can attenuate channelled flow, thus improving contact of the leach solution with the mineralized matrix. These results provide an integrated approach and multi-scale characterization of Naturally Fractured Reservoir (NFR) properties in sandstone, offering a basis for optimization of NFR production such as ISR development.

Published: February 2024

Abstract. This contribution shows part of a research activity aimed at supporting data documentation related to artworks and decorative apparatuses that characterize the architectural heritage using bSDD as a methodological tool. The proposal approach aims to provide specific information in SCAN-to-BIM processes, implementing HBIM models of decorative apparatuses or artworks with data on the state of conservation and morphological-structural composition according to the material of each component of the system (Lanzara and Scandurra, 2023). The main goal of this activity is the creation of open and detailed information models shareable and consultable via IFC exchange format (ISO 16739:2018), supporting conservation, prevention, maintenance and restoration of historical-artistic heritage. The use of codes, manuals, vocabularies and thesauri, and the multidisciplinary knowledge of specialists, shared within the theoretical and operational framework of the restoration and conservation of cultural heritage, informally contribute to supplement existing codes and to implement/define new datasets for information about deficient and not codified conservation states for specific materials. The structuring of the Data Dictionary is supported by ACCA software's usBIM.bSDD application, accessible via a collaborative web-based platform (Scandurra and di Luggo, 2023). According to the proposed workflow, shared terms and definitions can be integrated within the graphic model of the manufacts and structured within a CDE – Common Data Environment. The system, which has already been tested in the context of historical architecture, is currently being tested on movable and immovable decorative apparatuses and artworks, selected for their constituent materials and compositional complexity. This contribution presents the experimentation on the decorative apparatus of the major altar of the Church of Santa Maria di Costantinopoli in Naples.
CRAFTING AND MODIFYING RHINE CASTLE MODELS WITH PARAMETRIC MODELING IN BLENDER
Authors: Sommer E. , Koehl M. , Grussenmeyer P.
Published: February 2024

Abstract. In the domain of architectural heritage conservation, the recent advancements in 3D modeling have significantly improved the reconstruction fidelity of historical edifices, particularly medieval castles of the Rhine region. The existing traditional 3D modeling methodologies, though precise, are laborious and exceedingly time-consuming, requiring a detailed focus on intricate architectural nuances. Advancements in Building Information Modeling (BIM) technology have played a key role in simplifying this process, offering an adaptable and parametric approach to architectural modeling. Nonetheless, the domain of Historic Building Information Modeling (HBIM) faces the distinctive challenge of scarce parametric object libraries that are suitably representative of historical heritage, compounded by the architectural heterogeneity inherent in these ancient structures.This paper presents a novel methodology utilizing the Blender software suite, with an emphasis on exploiting ”Geometry Nodes” and ”Modifiers” for parametric modeling. We introduce a technique that significantly enhances the efficiency of modeling Rhine castles. This method supports rapid alterations and precise customization, catering to the specific analytical needs of archaeologists and heritage researchers. The proposed approach aims to bridge the gap in HBIM by providing a flexible, dynamic toolset for the accurate digital preservation of historical architecture.
LIVE PROCESSING AND FEEDBACK ON A COMBINED LASERSCANNING AND PHOTOGRAMMETRIC DOCUMENTATION WORKFLOW
Authors: Stampfer L.
Published: February 2024

Abstract. The use of a combined terrestrial laserscanning (TLS) and structure-from-motion (SFM) surveying approach has proved to be able to deliver advantageous benefits in terms of coverage and surface rendition. The elaboration of such approaches entails a succession of processes and are without many options for on-site feedback largely dependent on the experience of the surveyor. In support of this approach a combined automated processing workflow with augmented reality feedback is introduced, allowing operators to get a better understanding of their progress and project success during surveying. To do so native TLS and SFM software is connected to a shared network and data storage environment and controlled within an active framework. Within this, scans and images are aligned within RealityCapture and resulting registration is visualised to the operator using augmented reality (AR). To achieve complete independence of pre-scanned environments, the augmented reality application presented within this research uses a GNSS supported visual SLAM algorithm. With this the application is able to position virtual objects – such as markers representing the positions of registered cameras – within a physical space using only their geoposition as reference. The workflow presented here should be understood as a proof of concept to determine possible improvements that would enable such interactive means of surveying and would allow deeper integration of components into a combined AR supported documentation workflow.
DIGITISING SENSITIVE HERITAGE MONUMENTS IN ANTARCTICA
Authors: Westin J. , Almevik G.
Published: February 2024

Abstract. During the Antarctica expedition CHAQ2020, several cultural heritage sites – remains from the Swedish South Polar Expedition (1901–1903) – were documented using a range of different techniques and technologies. These physical monuments and environments are for all intents and purposes unavailable for most researchers due to their remote location and are also threatened by the effects of climate change. Hence, the deployed documentation techniques and technologies were selected both as a consequence of the inherently difficult conditions in Antarctica, where their reliance, durability, and speed were key considerations, but also for their perceived ability to document the unique and fragile environment. The documentation was carried out with the double intention of both allowing for observations in situ through processes of analytical drawings and data capture, but also capturing the environment as broadly and deeply as possible, in essence making a copy of it open for studies of unknown unknowns, that could serve as a source material for research questions still undefined. Hence, with the documentation of the winter station on Snow Hill Island as a case study, and with a perspective on documentation as a method through which to process, preserve, and disseminate information, this article serves to critically detail, compare, and evaluate the digital techniques and technologies that the expedition deployed to capture architectural elements and spatial contexts, and the data that could be obtained through these.

Published: February 2024

Abstract. Image classification and object detection techniques have been widely discussed and developed in recent years; they are the basis of various prosperous applications, for example, real-time mapping. Promising as it is, the practical test in the cultural heritage field encountered multiple problems. In this paper, the authors attempt to share the research experimentations and the empirical knowledge focusing on the classification and detection of architectural pathology. The tests are built on elaborated training sets annotated with analysed and in-advance defined categories. The trained models were examined from the perspective of evaluation sets, model explanation and unseen datasets. The outcomes indicated the mistakes and confusions behind things and stuff in the object detection efforts, to which cultural heritage and architectural field are closely related. The model also reveals specific visual patterns for recognition from thousands of instances in the training set. By digging into different aspects of model performance, the potential and limitations of these techniques in practical applications can be better understood.

Hybrid-Lambda: a low-specific-rating rotor concept for offshore wind turbines
Authors: Ribnitzky Daniel , Berger Frederik , Petrović Vlaho , Kühn Martin
Published: February 2024

Abstract. We introduce an aerodynamic rotor concept for an offshore wind turbine which is tailored for an increased power feed-in at low wind speeds by a substantial increase in the rotor diameter while maintaining the rated power. The main objective of the conceptual design is to limit the steady-inflow loads (blade flapwise root bending moment (RBM) and thrust) to the maximum values of a reference turbine. The outer part of the blade (i.e. outer 30 % span) is designed for a higher design tip speed ratio (TSR) and a lower axial induction than the inner part. By operating at the high TSR in light winds, the slender outer part fully contributes to the increased power capture. In stronger winds the TSR is reduced and the torque generation is shifted to the inner section of the rotor. Moreover, the blade design efficiently reduces the power losses when the flapwise RBM is limited through peak shaving, below rated wind speed. This is of high importance, given the wind speed distribution at offshore sites. The characteristics of the rotor are first investigated with stationary blade element momentum simulations and further analysed with aeroelastic simulations, considering the flexibility of blades and tower to show that a structural design is feasible even for a blade of this size and complexity. The economic revenue and the cost of valued energy of the turbine are estimated and compared to the IEA 15 MW offshore reference turbine, considering a fictitious wind-speed-dependent feed-in price. Our results for the turbine concept with an increase in rotor diameter by 36 % show that the revenue can be increased by 30 % and the cost of valued energy can be reduced by 16 % compared to the reference turbine.

STEM (Science, Technology, Engineering, Mathematics) is designed to explore what information is available to mechanical engineering students in higher education institutions and what work is being done there. Nowadays, modern teaching methods are used in educational institutions, and one of such methods is the STEM method. Based on global experience, we know that this method is an interdisciplinary approach used to provide students with a broad and deep education in the sciences. The widespread use of information and communication technologies in the field of science education has led to the emergence of a new type of educational experiment - a virtual experiment. This is considered a form of virtual simulation of STEM technologies. The implementation of virtual laboratories using computer programs that simulate physical processes virtually on a computer and allow changing its operating conditions and parameters is a type of STEM method. Such a program creates a unique situation for the implementation of interactive learning. We reviewed scientific literature published in peer-reviewed, high-ranking journals on the development of problem-solving abilities in STEM-rich physics teaching. Based on STEM education, mechanical engineering students were given stages of teaching specific content topics related to curriculum concepts. In order to increase the effectiveness of teaching the STEM method in laboratory classes of the Faculty of Mechanics, an article devoted to this issue discusses ways to use interactive modeling PhET, Algodoo - a digital programming language for 2D physical modeling, computer modeling "Open Physics". programs. One of the main principles of STEM education is to teach future physicists to acquire industrial experience and methodologically sophisticated research methods. The second important issue is the development of industrial business, that is, access to new ideas in response to production problems. It can be seen that the results obtained during the study of the STEM method of teaching in laboratory classes at the Department of Mechanics show great interest in providing students with teaching aids. The information obtained as a result of the study is recommended for use in higher and secondary educational organizations, and these results are the basis for new directions of research in the field of physics education.

Mn substituted copper ferrites (MnxCu1-xFe2O4, x = 0, 0.33, 0.67, 1.00) have been synthesized from metal nitrates and citric acid by sol-gel method (chemical process). This study aims to know the effects of Mn substitution on structural, magnetic, and electrochemical properties of copper ferrites. For characterizing the prepared ferrites, different techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared (FTIR) spectroscopy were used. In addition, vibrating sample magnetometer (VSM) is used to investigate the magnetic properties such as saturation magnetization (Ms), residual magnetism (Mr) and coercive force (Hc). A single-phase spinal structure was confirmed by XRD and lattice parameter was increased from 8.36 Å to 8.52 Å with increasing Mn contents. Micrographs of SEM shows that nanoparticles are agglomerated and non-uniform in size. The FTIR analysis shows that theses absorption band about 1422 cm-1 to 1434 cm-1 was attributed octahedral B-site. For pure copper ferrite, band is shifted towards higher frequency by manganese content. The results from CV showed that the increasing in scan rate and specific capacitance decreases due to increase in the area loop which clearly means that the investigated samples are best for storage devices such as lithium ion batteries (LIBs).

Vanlighet, försäkran och riskmedvetenhet: äldreboendens självpresentationer på Instagram under covid-19-pandemin
Authors: Carlstedt Elisabeth
Published: February 2024

Denna studie undersöker hur äldreboenden presenterade sina verksamheter på Instagram under covid-19-pandemins första år, genom kvalitativ analys av fyra intervjuer med företrädare för äldreboenden, samt 1748 bilder från två Instagramkonton.

Resultatet visar att medan boendenas företrädare i intervjuerna beskrev år 2020 som kaosartat, presenterades livet på äldreboendena på Instagram som aktivt och socialt, i likhet med presentationer från innan pandemin. Tre budskap identifierades i Instagrammaterialet: att verksamheten bedrevs som vanligt, att pandemin pågick, men att publiken inte behövde oroa sig, samt att pandemin pågick och var ett reellt hot.

Studien drar slutsatsen att budskapen på Instagram främst syftade till att lugna oroliga anhöriga under besöksförbudet, genom att utgöra motbilder mot en negativ medierapportering. Genom anpassning till publikens förväntningar kan verksamheter förmedla lugnande budskap och därmed skydda sitt anseende även i kriser. Även om presentationer på sociala medier förmedlar tillrättalagda budskap kan de för en utomstående publik betraktas som en attraktiv, aktuell och tillgänglig källa till information om vad som pågår på äldreboenden, särskilt då insynen är begränsad.

 

Normality, assurance, and risk awareness: Nursing homes’ self-presentations on Instagram during the Covid-19 pandemic

This study examines how nursing homes presented their daily activities on Instagram during the first year of the covid-19 pandemic, through a qualitative analysis of four interviews with representatives of these facilities and 1748 images from two Instagram accounts.

The results show that while representatives described the year 2020 as chaotic in the interviews, life in nursing homes was presented on Instagram as active and sociable, similar to presentations from before the pandemic. Three messages were identified in the Instagram material: that the daily activities were running as usual, that the pandemic was ongoing but the audience did not need to worry, and that the pandemic was ongoing and posed a real threat.

The study concludes that the messages on Instagram were primarily aimed at reassuring concerned family members during the visitation ban by providing counter-images to negative media reports. By adapting to the audience’s expectations, nursing homes can convey reassuring messages and thereby protect their reputation even in crises. Although social media presentations may convey curated messages, they can be perceived by an external audience as an attractive, current, and accessible source of information about what is happening in nursing homes, especially when transparency is limited.

Authors: Frizon André , Schaffel Esther Heloisa , Donato Francisco , Bello Rodrigo , Macagnan Mauricio Rizzi , Silva Fábio Goulart da , Sobrinho Henrique Rosa
Published: February 2024

Aortoesophageal fistula as a cause of upper gastrointestinal bleeding is a very rare event with a high immediate mortality rate. Some of the causes include foreign bodies, post-surgical complications, and malignancy. The following case describes how esophageal cancer invaded the walls of the descending aorta, leading to the formation of a pseudoaneurysm that subsequently fistulized into the esophagus, secondary to radiotherapy treatment. This case highlights the importance of evaluating the thoracic aorta before and during radiotherapy treatments, to investigate the existence of aortic vascular compromise adjacent to the esophagus. If the existence of an aortic pseudoaneurysm is detected, radiotherapy treatment should be suspended until the pseudoaneurysm is corrected, reducing the lethality of patients undergoing advanced treatments.

Published: February 2024

The peculiarities of the development and evolution of tuberculosis require a rich and varied diet to restore the nutritional status, reduce the incidence of gastrointestinal adverse reactions and increase adherence to treatment. Food can modify the pharmacokinetic parameters (Cmax, AUC, Tmax) and thus influence the effectiveness of antituberculosis drugs or contribute to the development of resistance. Rifampicin and isoniazid need to be taken on an empty stomach. Food does not significantly influence the pharmacokinetic parameters of pyrazinamide and ethambutol. Calcium-rich products will decrease the absorption of fluoroquinolones. Acidic drinks reduce the absorption and Cmax of cycloserine/terizidone and increase the absorption of paraaminosalicylic acid. Pharmacodynamic interaction can be observed when isoniazid is combined with products containing tyramine and histamine, with increased manifestations of adverse reactions.

Published: February 2024

Solid dispersions are one of the essential technologies for improving solubility and dissolution kinetics of drugs. They can be prepared in several ways and using different carriers. This technique is very suitable for class II BCS drugs, one of which is mefenamic acid. This paper is devoted to improving the solubility and dissolution rate of mefenamic acid by preparing solid dispersions using polyethylene glycol 4000, polyvinylpyrrolidone K30, and polysorbate 80 as carriers. Solid dispersions were prepared by kneading method, and dissolution was studied for two hours in phosphate buffer (pH=8). Experimental data of drug release from prepared solid dispersions were analysed according to different mathematical models. The results showed that the dissolution rate varied depending on the type and fraction of the carrier. However, mefenamic acid was released from all prepared formulations in accordance with the Higuchi model, and the release mechanism was better described by Fickian diffusion.

Conclusion: The two new method of estimation of oxetacaine like using Method 1: C18 column, 0.05% formic acid buffer: Methanol in the ratio 30:70 % v/v as mobile phase @214nm and Method 2: C8 Column, ammonium phosphate buffer pH 4.8: Acetonitrile in the ratio 25:75 % v/v as mobile phase @214 achieved with simple, precise, accurate and sensitive. In addition the quality control estimating of some of random of F1, F2, F3, F4, F5, and F6 marketed oxetacaine suspensions were analysed using this Two Optimized methods. Out of 6 formulations, 2 formulations F3, F6 determined as substandard quality on the both the methods. Hence proving these two new methods optimal for the further monograph inclusions as well as quality control predictions of oxetacaine in API as well as Finished Pharmaceutical Formulations.
The Musavat Azerbaijan Policy Towards Kurds: Parallels With Post-Soviet Azerbaijan’s Ethnic Policy
Authors: Tonoyan Artyom , Petrosyan Liana
Published: February 2024

The three censuses conducted in Azerbaijan during the post-Soviet period (1999, 2009, and 2019) reveal a significant decline (more than 300 percent) in the number of Kurds in the country over 20 years (1999-2019). This trend is consistent with Azerbaijan’s policies towards indigenous peoples and ethnic minorities. In this context, the situation parallels the experiences of other ethnic groups residing in Azerbaijan, including the Talysh people, Lezgins, Avars, and others. The primary objective of the present article is to examine the underpinnings of Azerbaijan’s policy towards indigenous peoples and ethnic minorities, with a specific focus on the Kurdish case. In terms of timeframe, the authors specifically chose the period of the first republic of Azerbaijan (1918-1920). This decision is based on the recognition that, when investigating the ethnic policy of Azerbaijan within this timeframe, the researcher is not necessarily obligated to address whether Azerbaijan could pursue an independent policy separate from the center (Moscow). This specific question gains relevance in the subsequent 70 years, covering the Soviet period, but does not apply to the years 1918-1920. When examining the issue, priority was given to the historical-comparative method by the authors. Accordingly, in selecting the temporal starting point for the examination, the period when Turkism was in action as a viable ideology in Azerbaijan was deemed pivotal.
Técnicas de cocción ancestrales resguardadas y aplicadas a la gastronomía de la región de Magdalena centro en Cundinamarca, Colombia
Authors: Galindo Galeano Luis , Bolaños Vásquez Angielo
Published: February 2024

Las técnicas de cocción ancestrales son testimonios históricos regionales; utensilios tradicionales, fuegos encendidos, y cada receta transmitida de generación en generación, que cuentan una historia que se remonta a las tribus precolombinas que poblaron esta tierra. Las costumbres culinarias revelan conexiones profundas entre las personas y la tierra que han habitado durante siglos. Explorar las técnicas de cocción ancestrales desde una metodología cualitativa, con enfoque etnográfico, en la gastronomía de la provincia de Magdalena Centro del departamento de Cundinamarca (Colombia), es un viaje en el tiempo y una inmersión en la cultura. La metodología se centró en la investigación de saberes culinarios ancestrales, profundizando en las técnicas de cocción; se desarrollaron visitas de campo, por un período de doce meses, así como entrevistas estructuradas y semiestructuradas a cocineros regionales, catalogados como expertos, además de cocineros locales, quienes aportaron sus conceptos y conocimientos. El propósito radica en preservar el patrimonio inmaterial culinario, adicionalmente, entender la influencia histórica en la gastronomía regional y plantear las bases para promover el turismo gastronómico. Se identifican técnicas preservadas como la cocción al vapor, asado, hervido, cocción en hojas, en tierra, en piedra y ahumado con hierbas aromáticas, las cuales han sido adaptadas a las condiciones contemporáneas del entorno. La exploración de las técnicas de cocción en la región de Magdalena Centro, contextualizada por la presencia histórica de tribus como los Muiscas, Laches y Guayupes, revela un viaje a través de la evolución gastronómica. La intersección de las prácticas culinarias ancestrales con las demandas contemporáneas ha sido marcada por la adaptación de dichas técnicas. Las entrevistas, análisis de encuentros, charlas y discusiones demuestran que desde los métodos precolombinos de cocción en tierra hasta la transición hacia estufas modernas, la culinaria ha sido moldeada por una conciencia creciente sobre la sostenibilidad y la eficiencia energética, sin olvidar el patrimonio ancestral.

The Spanish Survey of Household Finances 2020 (EFF2020) provides detailed information on the income, assets, debt and spending of Spanish households as at end-2020. Given the lack of alternative statistical sources that provide detailed household-level information on these variables for the same households, the concurrence of this edition of the survey with the COVID-19 pandemic makes it unique, allowing for all these variables to be analysed together in an exceptional setting. As in previous editions, this paper provides a detailed description of the most relevant methodological aspects of the design and implementation of the 2020 edition, including: the sample design, the questionnaire, the data collection process, the validation of the data, the computation of weights and the imputation procedures. In addition, it also describes the most important methodological changes that had to be implemented as a result of the pandemic, mainly the interviewing mode, which was switched from CAPI to CATI.
Grief in the school: A review of a participatory project in Argentina
Authors: Wainer Rafael , Nespral Alejandro , Radosta Darío-Iván
Published: February 2024

When a member of the education community (student, teacher, administrator) dies, there have historically been few options to process these distressing experiences inside the education environment. In this viewpoint article, we recount the historical and conceptual journey the organisation Fundación IPA (Palliative Ideas in Action) took to actively intervene in the often silenced (and frequently stigmatised) experiences of grief and bereavement in the City of San Carlos de Bariloche, Argentina.
Beyond prolonged grief: Exploring the unique nature of complicated grief in bereaved children
Authors: Lytje Martin , Dyregrov Atle
Published: February 2024

This article argues that the current approach to diagnosing complicated grief in children overlooks important social and personal factors that impact how children react to and cope with death. Family dynamics, community support, and individual reactions should all be considered when assessing and providing care. The article recommends a multifaceted approach to grief diagnosis that considers the child’s social environment. Helping parents navigate their own grief can support their child, and schools should create a welcoming and sensitive environment for bereaved children. By addressing these factors, negative consequences, such as social withdrawal, academic underachievement, and poor wellbeing, can be reduced.
Exceptional projections of sets exhibiting almost dimension conservation
Authors: Bushling Ryan E. G.
Published: February 2024

We establish a packing dimension estimate on the exceptional sets of orthogonal projections of sets satisfying an almost dimension conservation law. In particular, the main result applies to homogeneous sets and to certain graph-directed sets. Connections are drawn to results of Rams and Orponen.

An infinite iterated function system (IIFS) is a countable collection of contraction maps on a compact metric space. In this paper we study the conditions under which the attractor of such a system admits a parameterization by a continuous or Hölder continuous map of the unit interval.
CTJIF-ICN: A Coadjuvant Trust Joint Interest Forwarding Mechanism in Information Centric Networks
Authors: Delvadia Krishna , Dutta Nitul
Published: February 2024

The Information centric networks (ICN) transforms the focal point of current Internet paradigm to data centric approach from host centric approach by allowing content driven forwarding and in-network caching mechanisms. Though NDN (Named data networking) paradigm of ICN assures a secure content communication, it is vulnerable to different attacks by the malicious nodes. To minimize the hazards from compromised nodes and to improve the network security, the remaining nodes should transparently receive information about such nodes. This will restrict the forwarding strategy to exploit these malicious nodes for forwarding interest and content as well. Our protocol introduces a dynamic model for prediction of trust in order to evaluate the node trust. Proposed approach observes the historical behaviors of node and uses extended fuzzy logic rules for the prediction of future behaviors to evaluate the node’s trust value. This prediction model is incorporated within the trust based forwarding mechanism that aims to forward interest through secure and shortest path. The extensive simulation study has been carried out to analyze the protocol performance in ns-3 driven ndnSIM-2.0 simulator for performance metrics such as data discovery latency, packet delivery ratio, network overhead, detection ratio and cache hit ratio. When we integrate our trust joint forwarding strategy to state-of-the-art protocols, their performance is significantly improved up to approximately 10-35% against stated performance measures for realistic network topology.
