Until 2050, global urbanization will increase to 2.4 billion cities and towns. As the population grows, so does the consumption of fruits and vegetables. There will be a need for agricultural land and water resources. Nowadays, hydroponics is gaining popularity due to the plants exceedingly high quality and not required the large space and resources as like traditional planting. In this paper, a system which will be automatically control Electrical Conductivity (EC), Total dissolved solids (TDS), liquid levels, and power of hydrogen (pH) values is proposed to improve the Hydroponics Planting. This system is developed based on Neural Network for auto adjusting the value of hydrogen(pH) and nutrient in lettuce farm. It is designed to enable seamless data collection from various kinds of sensors in urban farm condition. The deployment of proposed system is tested in indoor urban farming environment. Through the experimental results, the proposed system can effectively regulate water and nutrients by assisting plant growth.
到2050年,全球城市化将增加到24亿个城镇。随着人口的增长,水果和蔬菜的消费量也在增加。对农业用地和水资源的需求将会增加。如今,水培因其植物品质极高,不像传统种植那样需要大的空间和资源而越来越受欢迎。为了提高水培栽培的质量,提出了一种自动控制电导率(EC)、总溶解固形物(TDS)、液位和氢功率(pH)值的系统。本系统是基于神经网络技术开发的一种用于莴苣田pH值和养分自动调节的系统。它旨在实现城市农场条件下各种传感器的无缝数据收集。在城市室内农业环境中对系统的部署进行了测试。实验结果表明,该系统能够通过辅助植物生长来有效调节水分和养分。

Software defect prediction is an integral part of the software development process. Defect prediction helps focus on the grey areas beforehand, thus saving the considerable amount of money that is otherwise wasted in finding and fixing the faults once the software is already in production. One of the popular areas of defect prediction in recent years is Heterogeneous Defect Prediction, which predicts defects in a target project using a source project with different metrics. Through our paper, we provide a novel feature selection based approach, En-BPSO, based on binary particle swarm optimization, coupled with majority voting ensemble classifier based fitness function for heterogeneous defect prediction. The datasets we are using are MORPH and SOFTLAB. The results show that the En-BPSO method provides the highest Friedman mean rank amongst all the feature selection methods used for comparison. En-BPSO technique also helps us dynamically determine the optimal number of features to build an accurate heterogeneous defect prediction model.
软件缺陷预测是软件开发过程中不可缺少的一部分。缺陷预测有助于预先关注灰色区域,从而节省了大量的资金,否则一旦软件已经投入生产,就会浪费在查找和修复错误上。近年来缺陷预测的一个流行领域是异构缺陷预测,它使用具有不同度量的源项目来预测目标项目中的缺陷。在本文中,我们提出了一种基于二元粒子群优化的基于特征选择的En-BPSO方法,结合基于多数投票集成分类器的适应度函数进行异质缺陷预测。我们使用的数据集是MORPH和SOFTLAB。结果表明,在所有用于比较的特征选择方法中,En-BPSO方法提供了最高的弗里德曼平均排名。En-BPSO技术还可以帮助我们动态确定最优特征数量,从而构建准确的异构缺陷预测模型。

In the radar positioning system, the unevenness of the atmospheric medium causes the deflection of the electromagnetic wave in the propagation process, which reduces the positioning accuracy of the radar, so it is necessary to correct the atmospheric refraction error for the radar's positioning requirement of fast positioning and high precision. Based on the method of correcting atmospheric refraction error by mapping function, the target's distance is regarded as the product of mapping function and altitude, and the application of mapping function in radar target positioning system is studied in order to reduce the complexity of positioning method and the dependence on atmospheric parameters, and an inversion method is used to study the change trends of mapping function's coefficients with altitude. Using the radar positioning environment established by Hopfield model, and taking the calculation result of raying tracing method as the radar observation data, the method's accuracy is studied. The results show that the mapping function method has research and application value in locating high elevation targets, and the accuracy of the positioning method is determined by the altitude and elevation angle of target. At a certain altitude, the closer the target is, the larger the elevation angle is, the smaller the positioning error is and the better the positioning effect is.
在雷达定位系统中,大气介质的不均匀性导致电磁波在传播过程中发生偏转,降低了雷达的定位精度,因此为了满足雷达快速定位、高精度的定位要求,有必要对大气折射误差进行校正。基于映射函数校正大气折射误差的方法,将目标距离视为映射函数与海拔高度的乘积,研究了映射函数在雷达目标定位系统中的应用,以降低定位方法的复杂性和对大气参数的依赖,并采用反演方法研究了映射函数系数随海拔高度的变化趋势。利用Hopfield模型建立的雷达定位环境,以射线跟踪法的计算结果作为雷达观测数据,研究了该方法的精度。结果表明,映射函数法在高程目标定位中具有研究和应用价值,定位方法的精度由目标的高度和仰角决定。在一定高度,距离目标越近,仰角越大,定位误差越小,定位效果越好。

Object detection has solved many problems in different applications like monitoring security, search and rescue operations, semantic segmentation, autonomous driving and so on. Despite this huge success rate in normal ground captured images, it is still a challenging task to detect humans or any other objects from the UAV(Unmanned Aerial Vehicle) captured images due to a few challenges like pose and scale variations, weather conditions, artefacts like people wearing hats, varying attitude and camouflaged environment. In this paper, we propose a novel approach for the detection of humans in aerial images, for search and rescue operations. This method explains how to train the existing high-resolution aerial database of HERIDAL. The EfficientDET deep neural network is trained using a newly generated database to solve the human detection problem. To the best of our knowledge, the proposed method has achieved the best accuracy of 93.29% mAP compared to all existing methods. The proposed method has been compared to the system used by Croatian Mountain search and rescue (SAR) teams (IPSAR) and also with the state-of-art proposed HERIDAL database paper which is based on extracting the salient features, which has slightly worse result compared to the results of this paper.
物体检测已经解决了监控安全、搜救行动、语义分割、自动驾驶等不同应用中的许多问题。尽管在正常的地面捕获图像中有巨大的成功率,但由于一些挑战,如姿势和规模变化、天气条件、戴着帽子的人等人工制品、不同的态度和伪装的环境,从无人机(无人机)捕获的图像中检测人类或任何其他物体仍然是一项具有挑战性的任务。在本文中,我们提出了一种新的方法来检测航空图像中的人类,用于搜索和救援行动。该方法解释了如何训练现有的HERIDAL高分辨率航空数据库。effentdet深度神经网络使用新生成的数据库进行训练,以解决人体检测问题。据我们所知,与所有现有方法相比,该方法的mAP精度达到了93.29%。将本文提出的方法与克罗地亚山地搜救队(IPSAR)使用的系统进行了比较,并与基于提取显著特征的最新提出的HERIDAL数据库论文进行了比较,结果略差于本文的结果。

A Simulation for Forecasting Compute Resource Usage 一种预测计算资源使用的仿真方法

The usage of compute resources by data processing jobs may change over time, requiring careful resource planning when an organization operates these resources itself in an on-premise private cloud. Ideally, the currently available resources always match the need of jobs executed on them. This way the resources would neither be overutilized, which is usually undesirable as the jobs might take longer, nor underutilized, which causes unnecessary costs for unused resources. When an organization decides to extend its private cloud resources, it can still take months until the servers are bought, delivered, and installed. Thus, the resources have to be planned carefully in advance. Estimating the future resource needs is difficult and influenced by many factors. In our experience, creating the estimate is often a manual process supported by self-designed spreadsheets; these spreadsheets are maintained by a single person from time to time and might even be replaced completely if someone else assumes that person's responsibility. However, this approach does not lead to transparent and verifiable forecasts that enable collaboration and learning from past decisions. This paper addresses the problem of generating a transparent and verifiable compute resource usage forecast by proposing a simulation approach. It requires a user to model an estimate of the future workload development of the data processing jobs as well as the current compute resource setup. The simulation can then be run to identify possible future resource bottlenecks. This can be repeated for different scenarios, including situations of failing resources as well as the addition of resources to compensate for bottlenecks and failures. We further provide a first qualitative case study of this approach that demonstrates its potential.
数据处理作业对计算资源的使用可能会随着时间的推移而变化,当组织在内部部署私有云中操作这些资源时,需要仔细规划资源。理想情况下,当前可用的资源总是与在其上执行的作业的需求相匹配。通过这种方式,资源既不会被过度利用(这通常是不希望的,因为作业可能需要更长的时间),也不会被未充分利用(这会导致未使用资源的不必要成本)。当组织决定扩展其私有云资源时,购买、交付和安装服务器仍然需要几个月的时间。因此,必须事先仔细规划资源。估计未来的资源需求是困难的,而且受到许多因素的影响。根据我们的经验,创建评估通常是一个由自己设计的电子表格支持的手动过程;这些电子表格不时由一个人维护,如果其他人承担了这个人的责任,甚至可能被完全取代。然而,这种方法不能导致透明和可验证的预测,从而使协作和从过去的决策中学习成为可能。本文提出了一种仿真方法,解决了生成透明且可验证的计算资源使用预测的问题。它要求用户对数据处理作业的未来工作负载开发以及当前的计算资源设置进行建模。然后可以运行模拟以确定未来可能出现的资源瓶颈。这可以在不同的场景中重复,包括资源失败的情况,以及为补偿瓶颈和故障而添加的资源。我们进一步提供了该方法的第一个定性案例研究,以证明其潜力。

E-procurement is an electronic procurement system that became a key factor required to manage financial aspect of a country with appropriate controls and protected by legal policies. The Presidential Regulation in Indonesia expect all government institutions to run the e-procurement process following the procurement principles, namely effective, efficient, transparent, open, competitive, fair and accountable. However in the implementation of e-tendering, which is part of e-procurement, found there are practices that not in accordance with the procurement principles. In this study, an in-depth analysis conducted to evaluate the tender activities of the ministry in Indonesia.

The study presents an analysis and generation of pattern sequences acquired from northern Luzon ethnic textiles. The textile sample images were collected, analyzed, and processed into a grayscale raster shapes. The analyzed data for pattern sequences was converted into a deterministic finite automaton which includes the transition tables and diagram. The experiment revealed that some patterns have similar sequences which were grouped together. Based from each grouped sequence, the sequences were analyzed, and an algorithm was developed. Each algorithm was used to generate a new pattern that is closely comparable to the grouped sequences. The study observed the following patterns which are a(bc)nbma, abna, and (ab) nam representing the common sequences appearing in the textile patterns.
本文对吕宋北部少数民族纺织品的图案序列进行了分析和生成。对纺织样品图像进行采集、分析,并处理成灰度光栅形状。将模式序列的分析数据转换为包含转换表和图的确定性有限自动机。实验显示,一些图案有相似的序列,这些序列被组合在一起。对每个分组序列进行分析,并给出相应的算法。每一种算法都被用来生成一个与分组序列密切相关的新模式。研究发现,a(bc)nbma、abna和(ab) nam是纺织品图案中出现的常见序列。
