Abstract—Machine and deep learning (DL) offer significant opportunities for exploring and monitoring oceans and for tackling important problems ranging from litter and oil spill detection to marine biodiversity estimation. Reasonably priced hardware platforms, in the form of autonomous (AUV) and remote operated (ROV) underwater vehicles, are also becoming available, fuelling the growth of data and offering new types of ap- plication areas. This article presents a research vision for DL in the oceans, collating applications and use cases, identifying opportunities, constraints, and open research challenges. We conduct experiments on underwater marine litter detection to demon- strate the benefits DL can bring to underwater envi- ronments. Our results show that integrating DL in underwater explorations can automate and scale-up monitoring, and highlight practical challenges in enabling underwater operations. This project introduces a refined YOLOv8-based algorithm tailored for the en- hanced detection of small-scale underwater debris, to mitigate the prevalent challenges of high miss and false detection rates . The research presents the YOLOv8 algorithm, which optimizes the backbone, neck layer, and C2f module for underwater characteristics and incorporates an effective attention mech- anism. This algorithm improves the accuracy of underwater trash detection while simplifying the computational model. Empirical evidence underscores the superiority of this method over the other conventional network, manifesting in a significant uplift in detection performance. Notably, the proposed method realized a 63% mean average precision (mAP50), a 60% surge in recall (R). Transcending its foundational utility in marine conservation, this methodology harbors potential for subsequent integra- tion into remote sensing ventures. Such an adaptation could substantially enhance the precision of detection models, particularly in the realm of localized surveillance, thereby broad- ening the scope of its applicability and impact.
摘要-机器学习和深度学习(DL)为探索和监测海洋以及解决从垃圾和溢油检测到海洋生物多样性评估等重要问题提供了重要机会。以自主式(AUV)和遥控式(ROV)水下航行器为形式的价格合理的硬件平台也逐渐面世,从而推动了数据的增长,并提供了新型应用领域。本文介绍了海洋中 DL 的研究愿景,整理了各种应用和用例,确定了机遇、限制因素和公开的研究挑战。我们对水下海洋垃圾检测进行了实验,以展示 DL 能为水下环境带来的好处。我们的研究结果表明,在水下勘探中集成 DL 可以实现监测的自动化和规模化,同时也凸显了水下作业所面临的实际挑战。本项目介绍了一种基于 YOLOv8 的改进算法,该算法专为加强小型水下碎片的探测而量身定制,以缓解普遍存在的高漏检率和误检率的挑战。研究提出了 YOLOv8 算法,该算法针对水下特征优化了骨干层、颈部层和 C2f 模块,并纳入了有效的关注机制。该算法提高了水下垃圾检测的准确性,同时简化了计算模型。经验证明,该方法优于其他传统网络,探测性能显著提高。值得注意的是,所提出的方法实现了 63% 的平均精确度(mAP50)和 60% 的召回率(R)。除了在海洋保护方面的基础用途外,该方法还具有与遥感技术结合的潜力。这种调整可以大大提高探测模型的精确度,特别是在局部监测领域,从而扩大其适用范围和影响。

SOEs are a crucial part of India's economic landscape, playing a vital role in various sectors. The governance frameworks within these entities are multifaceted, encompassing legislative provisions, regulatory directives, and oversight mechanisms. The Companies Act of 2013 lays down foundational principles, supplemented by guidelines from regulatory bodies like SEBI and DPE. Compliance with these frameworks is crucial for ensuring transparency, accountability, and ethical conduct within SOEs. However, Indian SOEs face challenges such as government interference in board decisions, lack of board autonomy, non-compliance with regulatory requirements, and the need to balance diverse stakeholder interests. These challenges often stem from the unique ownership structures of SOEs and their role in serving broader public policy objectives. Addressing these governance deficits requires concerted efforts from stakeholders, including the government, regulatory bodies, boards of directors, and management teams. Enhancing board independence, ensuring compliance with regulatory norms, and promoting transparency and accountability are essential steps towards strengthening corporate governance in Indian SOEs. Keywords: State-owned enterprises, corporate governance, India, Challenges, PSUs
国有企业是印度经济版图的重要组成部分,在各行各业发挥着重要作用。这些实体内部的治理框架是多方面的,包括法律规定、监管指令和监督机制。2013 年《公司法》规定了基本原则,并辅以 SEBI 和 DPE 等监管机构的指导方针。遵守这些框架对于确保国有企业内部的透明度、问责制和道德行为至关重要。然而,印度国有企业面临着政府干预董事会决策、缺乏董事会自主权、不遵守监管要求以及需要平衡不同利益相关者利益等挑战。这些挑战往往源于国有企业独特的所有权结构及其在服务于更广泛的公共政策目标方面的作用。要解决这些治理缺陷,需要包括政府、监管机构、董事会和管理团队在内的利益相关者共同努力。加强董事会独立性、确保遵守监管规范、提高透明度和问责制是加强印度国有企业公司治理的重要步骤。关键词国有企业、公司治理、印度、挑战、PSUs

New forms of crime have emerged with the rising prevalence of computer misuse. Some of them include the use of cutting-edge tools and methods for criminal conspiracy. From spreading fraud through email to stealing and reselling intellectual property, cybercrime covers a lot of ground. The domain of computer science known as "cyber forensics" is considered to be among the most essential subfields. It is concerned with the investigation of cybercrime. The concept of cyber forensics is broken down into its parts by the author in this paper. This paper focuses on the significance of the topic as well as some of the methods and instruments that are used by cyber forensic investigators. The objective of cyber forensics is to conduct an examination of electronic content in a manner that is forensically sound with the goals of preserving, recovering, analyzing, identifying, and presenting facts and views about digital information. Cyber forensics evidence undergoes the same processes as other digital evidence and serves as supporting evidence in judicial proceedings. Cyber forensics is often linked to the investigation of cybercrime, but it may also be utilized in legal actions involving private parties. This paper demonstrates the necessity for further investigation into how cyber forensics might be used to enhance the identification of cybercrime. This research will help fill in some of the gaps in our knowledge of how cyber forensics investigations are conducted in India and explore cyber security policy in the United Kingdom, the United States, and India to identify both similarities and differences.

Pub Date : 2023-12-01 DOI: 10.55041/isjem01318
S. Sushil, Mrs padmapriya
Government and industry environmental information disclosure is an important means to promote environmental supervision and law enforcement, and improve the level of environmental management. Public knowledge management is crucially dependent on public access to information – in particular, information on environmental risks. Yet most existing systems of governance favour administrative or corporate secrecy, thereby monopolizing environmental information in the hands of governmental authorities or private stakeholders. This paper describes innovative initiatives to establish civil society's 'right to know', by mandatory disclosure of government-held information and of industry-held environmental risk data (through the worldwide spread of Pollutant Release and Transfer Registers, and through court- enforced access to 'privileged' documentation However, the paper also highlights continuing transparency deficits (sometimes resulting in 'manufactured uncertainty') with regard to risk-sensitive information of common concern. Therefore, this paper believes that the government should strengthen the disclosure of environmental information based on urban economic development to ensure the sustainability of urban economic development.

政府和行业环境信息公开是推进环境监管执法、提高环境管理水平的重要手段。公共知识管理至关重要地依赖于公众获取信息——特别是关于环境风险的信息。然而,大多数现有的治理制度有利于行政或公司保密,从而使环境信息垄断在政府当局或私人利益相关者手中。本文描述了建立公民社会“知情权”的创新举措,通过强制披露政府持有的信息和行业持有的环境风险数据(通过在全球范围内传播污染物排放和转移登记册,以及通过法院强制获取“特权”文件)。该论文还强调了在共同关注的风险敏感信息方面持续存在的透明度缺陷(有时导致“人为的不确定性”)。因此,本文认为政府应根据城市经济发展情况加强环境信息披露,以保证城市经济发展的可持续性。研究者根据研究者提出的一些问题对同一事物进行了研究。受访者属于不同年龄组,国际科学工程与管理杂志ISSN: 2583-6129卷:02期:12 |十二月- 2023 DOI:10.55041/ISJEM01318 www.isjem.com国际学术||多学科||开放获取||所有主要数据库和元数据的索引©2023,ISJEM(所有权利保留)| www.isjem.com | Page 2教育和职业背景的调查问题基于对某些方面的一致性主题的认识水平和对概念的看法。结果是公式化的,假设要么被证明,要么被改变,这是任何研究都应该做的。研究中使用的工具包括社会科学统计工具(SPSS)。总之,人们应该给予足够的意识,以便他们有权获得有关环境的信息。关键词:环境监管,环境信息披露,绿色经济,产业与政府,门槛效应

SEISMIC ANALYSIS AND RETROFITTING OF BRIDGES BY USING FRAGILITY CURVES 利用脆性曲线对桥梁进行抗震分析和改造
Pub Date : 2023-09-24 DOI: 10.55041/isjem01315
R. D H, Ashwini Satyanarayana, P. P
Bridges, integral to transportation networks, face significant challenges from seismic events, impacting infrastructure resilience and public safety. This study focuses on developing fragility curves for bridges, providing a quantitative link between ground motion intensity and structural damage probability. Fragility curves offer insights into seismic vulnerability, considering factors like structural design, material properties, and local seismic conditions. The research explores various fragility curve development methods, emphasizing analytical approaches, and details Incremental Dynamic Analysis (IDA) as a vital tool. IDA, a parametric structural analysis, is employed to forecast bridge seismic responses, facilitating the derivation of fragility curves. The methodology guides bridge-specific IDA, involving seismic hazard assessment, structural modeling, and performance metric identification. By systematically evaluating fragility curves and considering retrofitting options, informed decisions can enhance the seismic resilience of bridges, contributing to the broader field of seismic risk assessment and infrastructure resilience. Key Words: resilience, Incremental Dynamic Analysis, retrofitting.

This research paper presents a comparative study on the assessment of blast-induced damage in reinforced concrete slabs, focusing on the comparison between numerical simulation and advanced structural analysis software. The objective is to evaluate the accuracy and reliability of both approaches in predicting structural damage caused by blast loading. The study utilizes numerical simulation techniques to model the dynamic behaviour of reinforced concrete slabs subjected to blast loading. Material properties, reinforcement details, and blast loading characteristics are incorporated into the simulations. The resulting structural response and damage are evaluated. In parallel, advanced structural analysis software, specifically MIDAS Civil software selected for its capabilities in blast analysis, is employed to analyse the same set of reinforced concrete slabs under blast loading. The software provides advanced modelling and analysis tools for assessing structural response and calculating blast-induced damage. By comparing the results obtained from the numerical simulations and the advanced structural analysis software, the study evaluates the agreement and capabilities of both approaches. Parameters such as displacements, strains, stress distributions, and damage patterns are examined. The findings contribute to the understanding of the accuracy and limitations of numerical simulation and advanced structural analysis software for blast-induced damage assessment. The results of this comparative study provide valuable insights for practitioners and researchers in blast engineering and structural assessment. The implications for blast-resistant design and recommendations for future research are discussed, aiding in the advancement of effective strategies for assessing and mitigating blast-induced damage in reinforced concrete structures. Keywords: Blast Analysis, Dynamic Linear Analysis, Response Spectrum Analysis, Prestressed Concrete.

FORMULATION AND EVALUATION OF OINTMENT CONTAINING CRISABOROLE 含crisaborole软膏的配方及评价
Pub Date : 2023-08-24 DOI: 10.55041/isjem01301
Shubham Vijay Patel
Crisaborole has broad-spectrum anti-inflammatory activity by mainly targeting phosphodiesterase 4 (PDE4) enzyme that is a key regulator of inflammatory cytokine production. As this enzyme is expressed in keratinocytes and immune cells, crisaborole mediates an anti-inflammatory effect on almost all inflammatory cells. Topical application of this drug is useful as it potentiates the localization of this drug in the skin and this anti-inflammatory activity is in the low micromolar range. The objective of present research work is to enhance the aqueous solubility of poorly water soluble drug Crisaborole using Co-solvency technique. The prepared formulation was evaluated for physical characteristics, drug content and drug release. Keywords: Crisaborole, Ointment, Co-solvency

Mouth dissolving film is now a days preferred route of drug administration due to patient compliance. The developed film formulation is a patient-friendly formulation that would be useful for people who have difficulty of swallowing. The results have shown that the HPMC-K4M is good film former and shows bioadhesion property. In combination with PEG-400, it has shown promising fast drug release within 10 min. and good folding endurance. Hence a semi-synthetic cellulose derivative which is affordable and abundantly available can be used as a potential drug release modifier and also used to improve flexibility and processability in the mouth dissolving films. Successful formulation of Cariprazine mouth dissolving films may prevent first pass metabolism to a large possible extent. From the present study it can be concluded that HPMC-K4M based mouth dissolving films of Cariprazine can be successfully prepared with considerable good stability and improved bioavailability Keywords: Mpouth dissolving, Cariprazine, Evaluation
