By collaborating horizontally, firms are expected to achieve considerable improvement. Most optimization approaches in coalition-based supply chain collaboration are single objective targeting cost reduction or profit maximization. Real-world decision problems usually require the investigation of more than one criterion to achieve a sustainable progress. In this paper, we study the collaborative facility and fleet sharing among firms at the same horizontal layer of the supply networks and explore the benefits of forming coalitions. We consider the case of suppliers operating their own distribution centers. Such firms have incentives to minimize their operational costs by optimizing inventory levels at warehouses, replenishment process and distribution to customers. The aim is to look at the trade-off between cost of the logistic service (warehousing and transportation) and maintaining customer satisfaction and loyalty by keeping, when possible, delivery service internal to each firm. The problem is a coalition formation modeled as a cooperative multiobjective game.
通过横向合作,企业有望取得相当大的进步。在基于联盟的供应链协作中,大多数优化方法都是以成本降低或利润最大化为目标的单一目标。现实世界的决策问题通常需要调查不止一个标准来实现可持续的进展。本文研究了处于同一供应网络水平层的企业之间的协作设施和车队共享,并探讨了形成联盟的好处。我们考虑供应商经营自己的配送中心的情况。这些公司有动力通过优化仓库库存水平、补充流程和向客户配送来最大限度地降低运营成本。其目的是考察物流服务(仓储和运输)成本与保持客户满意度和忠诚度之间的权衡,在可能的情况下,保持每个公司内部的交付服务。这个问题是一个以合作多目标博弈为模型的联盟形成。

Accidents can happen at any time and in any location, so emergency vehicles are essential in any emergency or life-threatening circumstance. However, due to lots of people owning cars, traffic jam is a severe problem in many cities. These traffic jams have an impact on emergency vehicles, particularly ambulances, as well as other vehicles such as fire trucks and police cars. The purpose of this research is to develop an emergency vehicle detection system that will assist law enforcement in mandating traffic when emergency vehicles are on the road. The researcher used deep learning, specifically the YOLov3 technique in developing the detection system wherein it will utilize CNN in implementation. The highest mAP value out of 25 models was obtained by the detection system is 98.78% by model 21.
事故随时随地都可能发生,因此在任何紧急情况或危及生命的情况下,应急车辆都是必不可少的。然而,由于许多人拥有汽车,交通堵塞在许多城市是一个严重的问题。这些交通堵塞对紧急车辆,特别是救护车,以及消防车和警车等其他车辆产生了影响。本研究的目的是开发一个紧急车辆检测系统,当紧急车辆在道路上时,该系统将协助执法部门强制交通。研究人员在开发检测系统时使用了深度学习,特别是YOLov3技术,其中将利用CNN实现。25个模型中,模型21的mAP值最高,为98.78%。

Analysis of Arterial Blood Gas (ABG) is an important investigation to measure oxygenation and blood acid levels. It is crucial in measuring the clinical status and contributes to an efficient and effective healthcare plan. Generally, ABG is applied in the emergency care units (ECU) and intensive care units (ICU). Most of the time, the doctors and nurses have difficulties identifying the type of respiratory failure with the help of ABG test results. So, during this research with the adaption of certain supervised machine learning approaches, namely Extreme Gradient Boosting (XGBoost), Adaptive Boosting (AdaBoost), Catboost, Random Forest, Naïve Bayes, Support Vector Machine (SVM), LightGBM, K-Nearest Neighbors (KNN), Neural Network (NN) and Decision Tree and have been incorporated with the intension of identifying the type of the respiratory failure with the highest accurate technique. To fulfil this purpose, 700 patient test results have been obtained from a public hospital in Sri Lanka. From the results discovered, XGBoost outperformed against all other techniques in identifying the type of respiratory failure with the highest accuracy of 98.65% and the lowest error rate of 1.35%. To ensure whether the XGBoost outperformed against the different percentages of training and testing data, K-fold cross-validation with five folds also has been performed with the dataset. The cross-validation produces results with an accuracy of 98.45% and the lowest error rate of 1.55%. In conclusion, XGBoost has been utilised in developing the prediction model. This would be a promising start for a future research scholar to adopt the hybrid techniques and the deep learning techniques to identify the causes of respiratory failure and the prediction of the type of respiratory failure.
动脉血气分析(ABG)是测定氧合和血酸水平的一项重要研究。它是衡量临床状况的关键,有助于制定高效有效的医疗保健计划。ABG一般应用于急诊(ECU)和重症监护(ICU)。大多数时候,医生和护士很难通过ABG测试结果来识别呼吸衰竭的类型。因此,在本研究中,采用了一些有监督的机器学习方法,即极端梯度增强(XGBoost)、自适应增强(AdaBoost)、Catboost、随机森林、Naïve贝叶斯、支持向量机(SVM)、LightGBM、k -近邻(KNN)、神经网络(NN)和决策树,并结合了以最高精度识别呼吸衰竭类型的技术。为了实现这一目的,从斯里兰卡的一家公立医院获得了700名病人的化验结果。从发现的结果来看,XGBoost在识别呼吸衰竭类型方面优于所有其他技术,准确率最高为98.65%,错误率最低为1.35%。为了确保XGBoost在不同百分比的训练和测试数据下是否表现出色,还对数据集进行了5倍的k倍交叉验证。交叉验证的结果准确率为98.45%,错误率最低为1.55%。综上所述,XGBoost已被用于开发预测模型。这将是未来研究学者采用混合技术和深度学习技术来识别呼吸衰竭的原因和预测呼吸衰竭类型的一个有希望的开始。

Following the pandemic, customers, preference for using e-commerce has accelerated. Since much information is available in multiple reviews (sometimes running in thousands) for a single product, it can create decision paralysis for the buyer. This scenario disempowers the consumer, who cannot be expected to go over so many reviews since its time consuming and can confuse them. Various commercial tools are available, that use a scoring mechanism to arrive at an adjusted score. It can alert the user to potential review manipulations. This paper proposes a framework that fine-tunes a generative pre-trained transformer to understand these reviews better. Furthermore, using "common-sense" to make better decisions. These models have more than 13 billion parameters. To fine-tune the model for our requirement, we use the curie engine from generative pre-trained transformer (GPT3). By using generative models, we are introducing abstractive summarization. Instead of using a simple extractive method of summarizing the reviews. This brings out the true relationship between the reviews and not simply copy-paste. This introduces an element of "common sense" for the user and helps them to quickly make the right decisions. The user is provided the pros and cons of the processed reviews. Thus the user/customer can take their own decisions.
疫情发生后,消费者使用电子商务的偏好加快了。由于单个产品的多个评论(有时是数千个评论)中提供了大量信息,这可能会导致买家决策瘫痪。这种情况剥夺了消费者的权利,他们不能指望自己去看这么多评论,因为这很耗时,而且会让他们感到困惑。有各种商业工具可用,它们使用评分机制来获得调整后的分数。它可以提醒用户注意潜在的审查操作。本文提出了一个框架,该框架对生成式预训练变压器进行微调,以更好地理解这些评论。此外,使用“常识”来做出更好的决定。这些模型有超过130亿个参数。为了根据我们的需求对模型进行微调,我们使用了生成式预训练变压器(GPT3)中的居里引擎。通过使用生成模型,我们引入了抽象摘要。而不是使用简单的提取方法来总结评论。这引出了评论之间的真实关系,而不是简单的复制粘贴。这为用户引入了“常识”元素,并帮助他们快速做出正确的决定。向用户提供经过处理的评论的优点和缺点。因此,用户/客户可以自己做决定。

The usage of femtocells, or micro macrocell base stations, increases energy efficiency which enhance quality of service for both indoor and outdoor customers. Femtocells were used in 4GP’s (Fourth Generation Project) LTE (Long Term Evolution) and advanced LTE like the 5G/6G networks to improve indoor coverage and capacity of the network. However, the random deployment of femtocells, as well as the large number and size variables, make controlling mobility even more difficult because mobile users increase day by day. This research investigates energy efficiency for femtocell mobility state detection algorithms to increase the QoS in LTE and advanced LTE networks (5G/6G networks). Several systems for detecting movement are currently in place. However, when it comes to cell type information and parameter scaling difficulties, they are found wanting as they help to improve the QoS. Overall handover performance suffers because of this gap that present techniques fail to address. As a remedy, this study presents an Improved Mobility State Detection Mechanism (IMSDM). As a result of the findings, IMSDM appears to be a viable way to improve energy efficiency for handover performance deterioration to increase the QoS and information about the cell type problems. It did not minimize the probability on Radio Link Failure (RLF), but it did give a decent trade-off among RLF likelihood since it is reduced and the quantity of Ping-Pong handovers.
使用飞蜂窝或微型宏蜂窝基站可以提高能源效率,从而提高室内和室外用户的服务质量。Femtocells被用于4GP(第四代项目)LTE(长期演进)和5G/6G等先进的LTE网络,以提高室内覆盖率和网络容量。然而,移动基站的随机部署,以及大量的数量和尺寸变量,使得控制移动性变得更加困难,因为移动用户日益增加。本研究探讨了移动蜂窝移动状态检测算法的能量效率,以提高LTE和高级LTE网络(5G/6G网络)的QoS。目前有几个检测运动的系统。然而,当涉及到单元类型信息和参数缩放困难时,发现它们在帮助改进QoS时存在不足。由于目前的技术无法解决这个差距,整体的移交性能受到影响。作为补救,本研究提出了一种改进的迁移状态检测机制(IMSDM)。由于这些发现,IMSDM似乎是一种可行的方法,可以提高切换性能恶化的能源效率,从而增加QoS和关于小区类型问题的信息。它并没有最小化无线电链路故障(RLF)的概率,但它确实在RLF可能性之间给出了一个不错的权衡,因为它减少了乒乓切换的数量。

Monitoring the CO2 gas level in a smart factory is essential as the high levels of CO2 gas negatively affect the human body, causing various physical problems. This paper presents an Internet of Things (IoT) based CO2 gas level monitoring and automated decision-making system inside a smart factory using the unmanned aerial vehicle (UAV) and multi-access edge computing (MEC) technique. Firstly, different IoT device is used to continuously monitor and detect the CO2 gas level data using gas sensors. Due to the drawback of sink node failure and the centralized data collection technique of wireless sensor networks, a UAV-based continuous CO2 gas level monitoring approach has been introduced in this study. Moreover, the MEC-enabled data processing technique is utilized by offloading the sensor data from the UAV considering its limited battery capacity and low processing power. Finally, a blockchain-based secure decision-making system is designed to evacuate the smart factory premises by alerting all employees in an emergency case of an excessive level of CO2 gas existence. Result analysis shows that the IoT devices can successfully monitor and detect the CO2 gas level in the smart factory using the UAV. Furthermore, the UAV can securely offload sensor data to the MEC server to analyze and make an automated decision to alert all employees in a smart factory to evacuate if CO2 levels are too high.
监测智能工厂中的二氧化碳气体水平是必不可少的,因为高浓度的二氧化碳气体会对人体产生负面影响,导致各种身体问题。本文介绍了一种基于物联网(IoT)的智能工厂二氧化碳气体浓度监测和自动化决策系统,该系统采用无人机(UAV)和多址边缘计算(MEC)技术。首先,使用不同的物联网设备使用气体传感器连续监测和检测二氧化碳气体水平数据。针对无线传感器网络存在的汇聚节点故障和集中采集数据的缺点,提出了一种基于无人机的CO2气体液位连续监测方法。此外,考虑到无人机有限的电池容量和低处理能力,通过从无人机卸载传感器数据利用MEC-enabled数据处理技术。最后,设计了一个基于区块链的安全决策系统,在二氧化碳气体含量过高的紧急情况下,通过提醒所有员工撤离智能工厂。结果分析表明,物联网设备可以使用无人机成功监测和检测智能工厂中的二氧化碳气体水平。此外,如果二氧化碳水平过高,无人机可以安全地将传感器数据卸载到MEC服务器进行分析并做出自动决策,提醒智能工厂的所有员工撤离。

Air pollution is invariably responsible for our health deterioration in many ways. In most cases, this health deterioration may cause severe illness to death. It is possible to reduce the effect of air pollution only if we get the real-time solution. As we spend most of our time in the building or in an indoor space it would be wise to monitor the surrounding air and get a notification through message or alert using IoT-based devices while there will be the presence of air pollutants. This paper is based on the review of different journal and survey papers. It reviews the different systems which can provide an IoT solution for Indoor Air Quality Monitoring to develop a smart health care environment.
空气污染在许多方面都是导致我们健康恶化的罪魁祸首。在大多数情况下,这种健康恶化可能导致严重疾病甚至死亡。只有我们得到实时的解决方案,才有可能减少空气污染的影响。由于我们大部分时间都在建筑物或室内空间中度过,因此明智的做法是监测周围的空气,并在存在空气污染物时使用基于物联网的设备通过消息或警报获得通知。本文是基于对不同期刊和调查论文的综述。它回顾了不同的系统,这些系统可以为室内空气质量监测提供物联网解决方案,以开发智能医疗环境。
