Aquaculture mainly refers to cultivating aquatic organisms providing suitable environments for various purposes, including commercial, recreational, public purposes. This paper aims to enhance the production of fish and maintain the aquatic environment of aquaculture in Bangladesh. This paper presents the way of using Internet of Things (IoT) based devices to monitor aquaculture’s basic needs and help provide things needed for the fisheries. Using these devices, various parameters of water will be monitored for a better living environment for fish. These devices consist of some sensors that will detect the Potential of Hydrogen (pH) level, the water temperature, and there will be two extra sections where the measurement of dissolved oxygen level and ammonia level using the testing kits can be determined which are needed for proper fish farming in the right water. An android-based mobile application has also been developed. In this system, farmers, fishermen, and people related to aquaculture will be the users of an android application. Via that application and with the help of a device, users will be notified about the amount of dissolved oxygen, ammonia level, pH level, and water body temperature. This monitoring system will help fish farmers to take the necessary steps to prevent any disturbance in an aquatic environment. Though Bangladesh is a riverine country and fish farming has a huge impact on this country’s economy, it is necessary to keep in good health to produce more and more fish. But the fisheries of this country are not expert enough to understand how to provide necessary elements to fish and what to do. They might get help from this system and measure the parameters they can give necessary things to grow more fish.
水产养殖主要是指为商业、娱乐、公共等各种目的而提供适宜环境的水生生物养殖。本文旨在提高孟加拉国的鱼类产量和维持水产养殖的水生环境。本文介绍了使用基于物联网(IoT)的设备来监测水产养殖的基本需求并帮助提供渔业所需的东西的方法。使用这些设备,将监测水的各种参数,为鱼类提供更好的生活环境。这些设备由一些传感器组成,可以检测氢电位(pH)水平,水温,还有两个额外的部分,使用测试套件测量溶解氧水平和氨水平,可以确定在合适的水中进行适当的养鱼所需要的。一个基于android的移动应用程序也被开发出来。在这个系统中,农民、渔民和与水产养殖相关的人将成为android应用程序的用户。通过该应用程序并在设备的帮助下,用户将收到有关溶解氧量、氨水平、pH值水平和水温的通知。这一监测系统将帮助养鱼户采取必要措施,防止对水生环境造成任何干扰。虽然孟加拉国是一个河流国家,渔业对这个国家的经济有着巨大的影响,但保持良好的健康才能生产出越来越多的鱼。但是这个国家的渔业还不够专业,不知道如何为捕鱼提供必要的元素以及该怎么做。他们可能会从这个系统中得到帮助,并测量参数,他们可以提供必要的东西来种植更多的鱼。

An Improved Time Feedforward Connections Recurrent Neural Networks 改进的时间前馈连接递归神经网络

Recurrent Neural Networks (RNNs) have been widely applied to deal with temporal problems, such as flood forecasting and financial data processing. On the one hand, traditional RNNs models amplify the gradient issue due to the strict time serial dependency, making it difficult to realize a long-term memory function. On the other hand, RNNs cells are highly complex, which will significantly increase computational complexity and cause waste of computational resources during model training. In this paper, an improved Time Feedforward Connections Recurrent Neural Networks (TFC-RNNs) model was first proposed to address the gradient issue. A parallel branch was introduced for the hidden state at time t − 2 to be directly transferred to time t without the nonlinear transformation at time t − 1. This is effective in improving the long-term dependence of RNNs. Then, a novel cell structure named Single Gate Recurrent Unit (SGRU) was presented. This cell structure can reduce the number of parameters for RNNs cell, consequently reducing the computational complexity. Next, applying SGRU to TFC-RNNs as a new TFC-SGRU model solves the above two difficulties. Finally, the performance of our proposed TFC-SGRU was verified through several experiments in terms of long-term memory and anti-interference capabilities. Experimental results demonstrated that our proposed TFC-SGRU model can capture helpful information with time step 1500 and effectively filter out the noise. The TFC-SGRU model accuracy is better than the LSTM and GRU models regarding language processing ability.
递归神经网络(RNNs)已被广泛应用于处理时间问题,如洪水预报和金融数据处理。一方面,传统rnn模型由于严格的时间序列依赖,放大了梯度问题,难以实现长期记忆功能。另一方面,rnn细胞高度复杂,这将大大增加计算复杂度,并在模型训练过程中造成计算资源的浪费。本文首次提出了一种改进的时间前馈连接递归神经网络(TFC-RNNs)模型来解决梯度问题。在t−2时刻的隐态直接转移到t时刻,不需要进行t−1时刻的非线性变换。这对于改善rnn的长期依赖性是有效的。在此基础上,提出了一种新的细胞结构——单门循环单元(SGRU)。这种细胞结构可以减少rnn细胞的参数数量,从而降低计算复杂度。接下来,将SGRU作为一种新的TFC-SGRU模型应用于tfc - rnn,解决了上述两个难题。最后,我们提出的TFC-SGRU在长期记忆和抗干扰能力方面的性能通过几个实验进行了验证。实验结果表明,我们提出的TFC-SGRU模型可以在时间步长为1500的情况下捕获有用信息,并有效滤除噪声。在语言处理能力方面,TFC-SGRU模型精度优于LSTM和GRU模型。

Today, resource waste is considered as one of the most important challenges in different industries. In this regard, the Rectangle Packing Problem (RPP) can affect noticeably both time and design issues in businesses. In this study, the main objective is to create a set of non-overlapping rectangles so that they have specific dimensions within a rectangular plate with a specified width and an unlimited height. The ensued challenge is an NP-complete problem. NP-complete problem, any of a class of computational problems that still there are no efficient solution for them. Most substantial computer-science problems such as the traveling salesman problem, satisfiability problems (sometimes called propositional satisfiability problem and abbreviated SAT or B-SAT), and graph-covering problems are belong to this class. Essentially, it is complicated to spot the best arrangement with the highest rate of resource utilization by emphasizing the linear computation time. This study introduces a time-efficient and exploratory algorithm for the RPP, including the lowest front-line strategy and a Best-Fit algorithm. The obtained results confirmed that the proposed algorithm can lead to a good performance with simplicity and time efficiency. Our evaluation shows that the proposed model with utilization rate about 94.37% outperforms others with 87.75%, 50.54%, and 87.17% utilization rate, respectively. Consequently, the proposed method is capable to of achieving much better utilization rate in comparison with other mentioned algorithms in just 0.023 s running-time, which is much faster than others.
今天,资源浪费被认为是不同行业最重要的挑战之一。在这方面,矩形包装问题(RPP)可以显著影响企业的时间和设计问题。在本研究中,主要目标是创建一组不重叠的矩形,使它们在具有指定宽度和无限高度的矩形板内具有特定的尺寸。接下来的挑战是np完全问题。np完全问题,任何一类仍然没有有效解的计算问题。大多数实质性的计算机科学问题,如旅行推销员问题、可满足性问题(有时称为命题可满足性问题,缩写为SAT或B-SAT)和覆盖图形的问题都属于这一类。从本质上讲,通过强调线性计算时间来确定具有最高资源利用率的最佳安排是复杂的。本文介绍了一种省时的探索性RPP算法,包括最低前线策略和最佳拟合算法。实验结果表明,该算法具有简单、省时的优点。我们的评估表明,该模型的利用率为94.37%,优于其他模型的利用率分别为87.75%、50.54%和87.17%。因此,与其他算法相比,该方法能够在0.023 s的运行时间内实现更好的利用率,比其他算法快得多。

In sugar production, model parameter estimation and controller tuning of the nonlinear clarification process are major concerns. Because the sugar industry’s clarification process is difficult and nonlinear, obtaining the exact model using identification methods is critical. For regulating the clarification process and identifying the model parameters, this work presents a state transition algorithm (STA). First, the model parameters for the clarifier are estimated using the normal system identification process. The STA is then utilized to improve the accuracy of the system parameters that have been identified. Metaheuristic algorithms such as Genetic Algorithm (GA), Particle Swarm Optimization (PSO), and State Transition Algorithm are used to evaluate the most accurate model generated by the algorithms. By capturing the principal dynamic features of the process, the clarifier model produced from State Transition Algorithm (STA) acts more like the actual clarifier process. According to the findings, the controllers provided in this paper may be used to achieve greater performance than the standard controller design during the control of any nonlinear procedure, and STA is extremely helpful in modeling a nonlinear process.
