Authors: N.H. Badrulhisam , S.A. Sajib , H.H. Teo , A.A. Ahmad Zamri
Published: August 2023

In recent years, automotive chassis has developed tremendously. This includes the roll cage chassis type which has a higher centre of gravity. This will require an optimum number of truss members to ensure the rigidity and safety of the chassis and user. This research paper aims to analyse the roll cage chassis frame using static analysis simulation by removing truss members at the bottom of the chassis for each design. Carbon steel was employed for all chassis designs. Then, static analysis simulation was done using Autodesk Inventor 2023. From the static analysis, a load equal to 6300 N was applied to the chassis. The safety factor, von Misses stress, 1st principal stress, and 3rd principal stress were analysed and compared for each of the designs. The result shows that the lowest safety factor starting from Design 1, Design 2 and Design 3 with the values of 2.13, 1.85, and 3.24, respectively. For the 1st principal stress, the values are 97.39 MPa, 329.5 MPa, and 104 MPa for Design 1, Design 2, and Design 3, respectively. This result is good as the ultimate strength of carbon steel is 695 MPa. While for the 3rd principal stress, the values are 20.2 MPa, 96.4 MPa to 37.6 MPa for Design 1, Design 2, and Design 3, respectively. In conclusion, removing a few truss members will affect the static analysis performance. It is determined that Design 2 has an optimum truss members number compared to the other two designs.

Authors: Leontiev S. Yu. , Piyanova S. V. , Ulchenko V. A. , Kamshukov S. V.
Published: August 2023

Purpose of work: comparative analysis of the available methodological approaches to the assessment of the amount of commercial fish species taken by IUU fishing and IUU bycatch in the implementation of fisheries on the example of individual regions of the Russian Federation, including inland water bodies of different fishery basins.

   Methods used: comparative analysis of methodological materials on assessment of IUU fishing, used in different branches of VNIRO.

   Novelty: for the first time an analysis of various methods for assessing the extraction of commercial fish species by IUU fishing has been conducted; the presented generalized data on the assessment of illegal catches in different fishery basins of the Russian Federation show that the amount of IUU fishing is the volume which often exceeds the values of the total allowable catches (TAC) and the recommended volumes of production (catch) of aquatic bioresources.

   Practical significance: Refinement of methodical approaches of estimation of IUU fishing and IUU bycatch will allow receiving a characteristic picture of size of IUU fishing for various fishery basins taking into account specifics of fishery basins, species composition of catches and applied gears of catch. The resulting data on the value of IUU-catch of commercial fish species will be used to clarify (adjust) the projected volume of production (catch) of commercial fish in Russia.

On the Improvement of Pink Salmon Fishery Management (on the Sakhalin- Kuril Region as an example)
Authors: Kaev A. M. , Samarsky V. G. , Glubokovsky M. K.
Published: August 2023

Purpose: Assess the current state of the pink salmon fishery management and determine ways to improve the scientific support of the pink salmon fishing to ensure the rational usage of its stocks.

   Methods used: Analysis of historical data and methods used to assess the state of pink salmon stocks and develop recommendations for their usage.

   Results: Over the past decade, discrepancies between expected and actual returns of pink salmon, to the eastern coast of Sakhalin in particular, have averaged more than double. Those inconsistencies are associated both with many uncertainties in the development of forecasts and with the representativeness of the data used. Wrong estimates form the basis of the submitted fishing strategies, which negatively affects operational fishing management. Using the returns of pink salmon in 2021–2022 as an example, it is shown that the accuracy of forecasting could be higher when using standardized primary data, for which it is necessary to restore the corresponding database, the support of which was interrupted in 2015. It is also proposed to focus on strengthening operational forecasting as a basis for the development of fishery management measures.

   Practical significance: Restoration of the primary database and return to previously well-established methods of fishery management should increase the effectiveness of scientific part in pink salmon fishery of the region.

Published: August 2023

Sediments within the depth intervals of 2834-6620.9 ft in Well TMG-08 of Opolo Field, Niger Delta, were investigated with the aim of establishing its lithofacies, depositional environments and petrophysical characteristics using a suite of Well-Logs. The Shale lithology is more dominant and of thicker units than the sand at the upper section of the log which could be interpreted as sediments of the Akata Formation. Five sand bodies were identified within the study interval. The shapes of the gamma ray signatures were funnel, cylindrical and symmetrical. Prograding, aggradational and combined prograding and retrograding parasequences were identified from the stacking patterns of the gamma ray curves. The environments of deposition delineated were Transgressive shelf sands and mixed Tidal flat environment, Crevasse splay, River mouth bar, Delta front shoreface, and Fluvial channels, Tidal sands, Prograding delta distributaries. The predicted porosity and permeability show moderate to good quality reservoirs. The average porosity value (0.13 *100= 13% Ranging from Poor to moderate), with a moderate permeability Value (16.87mD) due to the presence of high volume of shale in the reservoirs. The thicknesses of the reservoir are small averaging 5.5ft (16.92m). The depositional environment shows that sand B and C are continuous within the reservoir. The environment of deposition of the study area lies within the marginal marine
Contextual Emotion Recognition Using Transformer-Based Models
Authors: Devgan Aayush
Published: August 2023

In order to increase the precision of emotion identification in text, this research suggests a context-aware emotion recognition system employing transformer models, especially BERT. The model is able to comprehend complex emotions and context-dependent expressions since it was trained on a broad, emotion-labeled dataset. On a benchmark dataset, its efficacy is assessed in comparison to conventional techniques and standard transformer models. The system is proficient at gathering contextual information, and the findings demonstrate a considerable improvement in emotion recognition accuracy. This study improves textual emotion identification, opening the door to applications like chatbots that can recognize emotions and systems for tracking mental health. It also identifies potential areas for further study in developing transformer models for context-sensitive NLP applications.
A Single-Event Transient (SET) Tolerant Dynamic Bias Comparator in 65-nm CMOS
Authors: Ash Andrew , Hu John
Published: August 2023

A single-event transient (SET) tolerant dynamic bias comparator leveraging path-splitting is presented in this paper. The dynamic bias structure with a tail capacitor is found to be vulnerable to positive and negative SET transients. A negative transient on the tail transistor doubles the energy per conversion. A positive transient on the tail MOS capacitor reduces the preamplifier gain by 35.7%, which increases the metastability error rate in the subsequent latch. A path splitting technique is applied to mitigate the positive SET. Simulations in a 65-nm CMOS process showed that a two path split can recover the comparator output voltage swing by 12.7%. Compared with the state-of-the-art CMOS radiation-hardened by design (RHBD) dynamic comparators, this circuit achieved the lowest energy per comparison while maintaining low input referred noise and gaining SET tolerance in the evaluation phase.

Authors: Tjoa Erico , Xie Feng , Shu Chi-Hung , Xue Lei , Aghaeepour Nima , Guan Cuntai
Published: August 2023

Feature attribution methods have been widely employed in the eXplainable Artificial Intelligence (XAI) community and they have been designed with various underlying concepts. As a consequence, these methods sometimes assign different feature importance on the same data. To resolve the possible discrepancies, we introduce \textit{endorsed attributions}, a voting mechanism that integrates the strengths of different feature attribution methods on healthcare datasets: maternal health risk classification, body signal of smoking, fetal health and heart disease classification. Our methods generate simplified visualization charts as an explainable AI use case in clinical settings, avoiding the need for end users like patients or medical practitioners to focus too deeply on technical nuances. Graph visualizations from our partitioning methods also reveal the differences between correct and wrong predictions. Finally, we demonstrate how the extraction of endorsement cores (EEC) can be used for data pruning, and models trained on the resulting EEC data subset can achieve competitive performance.

GT-DTW: Bridging Graph Theory and Dynamic Time Warping for Complex Time Series Analysis
Authors: Mahajan Sachit
Published: August 2023

Classification of time series data plays a critical role across various domains, enabling pattern recognition and trend prediction. Traditional methods like Dynamic Time Warping (DTW) have been widely used to measure similarity between time series, but there are challenges related to computational complexity and sensitivity to noise. The conventional DTW approach, with its quadratic time complexity, can be inefficient for large datasets, and some implementations may struggle with noise and local variations. To overcome these limitations, a novel method called Graph-Theoretic Dynamic Time Warping (GT-DTW) is proposed. GT-DTW represents each time series as a graph, applies DTW on the graph representations and calculates the distances between different time series based on these graph representations. This approach provides a robust and computationally efficient method for time series classification, and experimental results show that GT-DTW provides better results when compared with conventional methods on the benchmark datasets from the UCR time series database. GT-DTW also demonstrates enhanced effectiveness in situations where time series share fundamental similarities, yet are affected by intricate transformations, noise, inconsistencies in length, and localized distortions.

Between offshore competition and a duopoly: Gambling provision on and from the Finnish Åland Islands
Authors: Nikkinen Janne , Pihkala Anni , Marionneau Virve
Published: August 2023

This paper explores the legal and social status of the Åland-based gambling company Paf. Gambling and the gambling industry have increasingly moved online. Online provision has had implications for policy particularly due to increased competition in domestic markets from offshore gambling. In offshore gambling, unlicensed operators do not follow predetermined legal rules. Yet, there has been little research addressing the definition of offshore provision. Paf is an excellent example of a company that operates several roles: it is a monopoly on Åland, a licensed operator in some European jurisdictions, and an offshore operator in Mainland Finland. This paper uses key informant interviews (N=5) and legislative texts to study the social and legal implications of Paf's offshore operation. The findings show that offshore provision is heterogeneous and legally complex. A company such as Paf can at the same time operate within the legal framework and provide offshore gambling. This possibility has made Paf very profitable for and socially accepted on the Åland Islands.

This article is devoted to the issues of restoring the performance of fi re pressure hoses in a fi re when punctures, cuts
and fi stulas occur. Failure of fi re pressure hoses in a fi re occurs due to mechanical damage during the laying of main and
working lines. In this case, an increase in the working pressure in the bag system leads to the loss of extinguishing agents
and the appearance of fi stulas, longitudinal and transverse breaks. This article offers a technical solution aimed at developing
a new clamp design to restore the performance of a fi re pressure hose with a diameter of 55 mm when it is damaged:
a puncture or cut. For this purpose, a three-dimensional model of the clamp was developed and its strength analysis was
performed using the Autodesk Inventor computer-aided design system. This device will allow you to restore the supply of
fi re extinguishing agents in the shortest possible time if the pressure hoses are damaged in a fi re.

Penelitian ini dilakukan untuk mengetahui selektivitas dan efektivitas alat tangkap tampirai yang digunakan dalam menangkap ikan, mengetahui jenis dan jumlah ikan hasil tangkapan tampirai serta mengetahui aspek biologi ikan yang tertangkap meliputi hubungan panjang berat, tingkat kematangan gonad (TKG) dan indeks kematangan gonad (IKG). Penelitian ini dilaksanakan Februari 2020. Lokasi penelitian ini bertempat di Sungai Sebangau Kelurahan Kereng Bangkirai Kecamatan Sebangau Kota Palangka Raya. Berdasarkan hasil penelitian bahwa panjang ikan kapar, patung dan emplekung yang pertama kali tertangkap dimodelkan dengan L50% (50%) yaitu memiliki panjang 15,4 cm, 16,40 cm dan 15,87 cm. Hal ini menandakan bahwa ukuran ikan yang tertangkap selektif sesuai dengan ukuran tetapi tidak selektif pada tingkat kematangan gonad ikan karena rata-rata ikan yang tertangkap bertelur/matang gonad. Alat tangkap tampirai merupakan alat tangkap yang efektif karena mampu menghasilkan tangkapan per alat tangkap ± 1 kg dan dalam sekali tripnya mampu menghasilkan tangkapan sebanyak 14 kg. Selain efektif alat tangkap ini menguntungkan bagi perekonomian nelayan.
hysiological and Behavioural Responses of Lake Trout to Catch-And-Release Angling
Authors:   , Howell Bradley E.
Published: August 2023

Lake trout (Salvelinus namaycush), like many other native fishes in North America are a popular species typically targeted for recreational angling. Catch-and-release angling (C&R) relies on the assumption of high fish survival following release and is considered an effective way to preserve wild stocks of fish. Salmonids and other related species are susceptible to recreational angling, which can induce stress during different parts of the process (e.g., line fighting and air exposure). Other factors can impact fish health (e.g., water temperature and hooking location) and potentially lead to delayed mortality. In this thesis, I present empirical research where I used reflex impairment, physiology, and overall activity to assess the robustness of lake trout to C&R across seasons and time scales. During ice angling, lake trout experienced signs of reflex and physiological impairment up to 6 h and a high mortality rate. A key finding was that lake trout may exhibit pressure-related injuries in cooler water temperatures despite being physostomous. During open water angling, lake trout experienced barotrauma, reflex impairment, and physiological impairment immediately upon capture and 0.5 h post-angling. The addition of post-release activity monitoring via tri-axial accelerometry showed that lake trout rapidly swim to depth and exhibit reduced activity for the first 14 min after release. Collectively, I demonstrate that using multiple metrics of assessing angling-related impairment (i.e., both external and internal metrics) is necessary and future studies should not rely on one or few indices. The work presented here provides new information regarding context-specific aspects of C&R and is useful for recreational fisheries management.
