Soft robots being one of the most diverse fields in robotics, these robots are robust, flexible and allow for a highly diverse field of implementation and movement. The property to withstand force and to perform actions The major problem with wheeled bots and bipeds is that they are not versatile enough to adapt and work. The major problem with other soft robots is that they require external supply and external wiring which strains the motion and strains the path of the robot while functioning. This not only makes the robot bounded but also makes it restrained to a standard structure. The motion and path planning of the robot is constrained because of the wires. like walking and moving are one of the key features that can be seen in all these robots. The major advantage of these robots includes versatile design and multi-terrain property. The motion and movement of these robots are usually actuated using actuators and motion controllers. Major design implementation and major functionality added to all these actuators is related with the type of motion it needs to perform. The proposed design is solving the problem of linear motion and linear motion underwater and on the ground.
软机器人是机器人技术中最多样化的领域之一,这些机器人具有鲁棒性,灵活性,并且允许高度多样化的实施和运动领域。轮式机器人和两足机器人的主要问题是它们的适应性和工作能力不够全面。其他软体机器人的主要问题是它们需要外部电源和外部线路,这使得机器人在工作时运动和路径变得紧张。这不仅使机器人有界,而且使其受到标准结构的约束。由于导线的存在,机器人的运动和路径规划受到约束。行走和移动是所有这些机器人的关键特征之一。这些机器人的主要优点是多用途设计和多地形特性。这些机器人的运动和运动通常是使用致动器和运动控制器来驱动的。所有这些执行器的主要设计实现和主要功能都与它需要执行的运动类型有关。本设计解决了水下和地面的直线运动和直线运动问题。

Localization of sensor nodes in wireless sensor networks (WSNs) is one of the major challenges. It helps in evaluating the position of an unsettled object. In wireless sensor network, energy utilization is the important matter in localization of nodes. In WSNs, sensor nodes are situated in the network for one time. But in real life, it was found that few nodes may stop working and become dead. This may be happened due to battery failure or any technical fault. In this case, extra nodes are situated in the network to overcome the communication hole. The purpose of this research is to minimize the computational time by considering only extra nodes for relocalization. For this purpose, we have proposed two methods using particle swarm optimization (PSO) based distance vector hop (DV-Hop) relocalization for estimating the position of unknown nodes. Through simulation results, we conclude that our PSO DV-Hop effectively minimizes the computation time and localization error.
无线传感器网络(WSNs)中传感器节点的定位是一个主要的挑战。它有助于评估不稳定物体的位置。在无线传感器网络中,能量利用是节点定位的重要问题。在无线传感器网络中,传感器节点只在网络中存在一次。但在现实生活中,人们发现少数节点可能会停止工作并死亡。这可能是由于电池故障或任何技术故障造成的。在这种情况下,在网络中设置额外的节点来克服通信漏洞。本研究的目的是通过只考虑额外的节点进行重新定位,从而最大限度地减少计算时间。为此,我们提出了两种基于粒子群优化(PSO)的距离向量跳(DV-Hop)重定位方法来估计未知节点的位置。仿真结果表明,该算法有效地降低了定位误差和计算时间。

Suicide analysis is an area of vital importance to the National Institute of Mental Health and various other agencies working in the field of suicide prevention. Studying on this aspect helps to analyze the suicide pattern and trends that suicides follow over the years. This paper explores time-series data of the suicides that occurred in India to find whether there is a notable change in trend after a certain time point. A predictive approach is applied to forecast into the future of the suicide trend. The paper applies Facebook Prophet, a time-series prediction algorithm for drawing inferences and conclusions. The paper also suggests an inflection point algorithm that highlights the suicide trend between two points in time. Additionally, the model is also capable of predicting the trend for “n” number of years to come. We have used MAPE and SMAPE error techniques for accurate measurement. The mean absolute percentage error (MAPE) is a predictive accuracy measure while the symmetric mean absolute percentage error (SMAPE) is a percentage (or relative) error-dependent accuracy measure. The values of MAPE and SMAPE were found to be in the range of 0.1-0.2 and less than 12 respectively. The conclusion derived is that the result is an increasing nature in the current year and there is a need for utmost attention.
自杀分析对美国国家心理健康研究所和其他从事自杀预防工作的机构来说是一个至关重要的领域。这方面的研究有助于分析多年来自杀的模式和趋势。本文对印度发生的自杀事件的时间序列数据进行了研究,以确定在某个时间点之后是否存在显著的趋势变化。采用预测方法对未来自杀趋势进行预测。本文采用时间序列预测算法Facebook Prophet进行推论和结论。本文还提出了一种拐点算法,该算法突出了两个时间点之间的自杀趋势。此外,该模型还能够预测未来n年的趋势。我们使用MAPE和SMAPE误差技术进行精确测量。平均绝对百分比误差(MAPE)是一种预测精度度量,而对称平均绝对百分比误差(SMAPE)是一种百分比(或相对)误差依赖的精度度量。MAPE和SMAPE的取值范围分别在0.1 ~ 0.2之间,小于12。得出的结论是,今年的结果是增加的性质,需要高度重视。

We analyze EYDFA + Raman + EYDFA (E+R+E) and Raman + Erbium (R+E) hybrid optical amplifiers (HOA) configurations in C-band at 1560 nm for an ultra-dense wavelength division multiplexing (UD-WDM) system. The HOA has been evaluated in terms of gain, gain ripple, noise figure (NF) and optical signal to noise ratio (OSNR) at two data rates of 10 and 100 Gb/s. HOAs have also been analyzed at different input power levels changing from 0.1 to 0.001 mW for both the data rates. The HOA high and flat gain of 65 dB with 8 dB of NF has been attained with an input power of 0.001 mW at a data rate of 10 Gbps. EYDFA + Raman + EYDFA HOA outperforms the Raman + EYDFA; as the highest gain of 64 dB achieved with a low value of gain ripple of approximately 3 dB.

With the help of active sensory organs viz. eyes, ears, nose, tongue and skin, living beings perceive the environment around them. Humans exhibit a sense of self learning since birth and the sensory organs play a vital role in the learning process. For those unfortunate, who lose any of the sensory capability, try to sense the environment through other sensory organs available. Such persons are called differently-abled. Those with loss of sight are called visually impaired. There are a few passive devices to augment the partially defunct senses such as spectacles, hearing aids etc. While these devices help boost existing senses they do very little for those with complete absence of the sense. Present day technological advances have opened a galore of possibilities in designing solutions to provide learning support to perceptually disabled. Multimedia computers and hand held devices can be effectively used to find new solutions. This paper presents a novel approach for the use of vibrations of a hand held mobile phone, as an alternative to vision in helping the visually impaired persons in perceiving things especially colours. The authors have developed an android mobile phone application to prototype the methodology to use mobile phone's motor as the source for vibration and mapping a vibratory pattern with colours. With mobile phones being widely used, the authors find this approach as a potential solution in designing applications to assist the visually impaired in their learning process.
生物通过眼睛、耳朵、鼻子、舌头和皮肤等活跃的感觉器官来感知周围的环境。人类自出生以来就表现出自我学习的意识,感觉器官在学习过程中起着至关重要的作用。对于那些不幸的人来说,他们失去了任何感觉能力,试图通过其他可用的感觉器官来感知环境。这样的人被称为残疾人士。那些失去视力的人被称为视障人士。有一些被动设备可以增强部分丧失的感官,如眼镜、助听器等。虽然这些设备有助于增强现有的感官,但对那些完全没有感官的人来说作用很小。当今的技术进步为设计解决方案提供了大量的可能性,为感知障碍提供学习支持。多媒体电脑和手持设备可以有效地用于寻找新的解决方案。本文提出了一种利用手持移动电话振动的新方法,作为视觉的替代,帮助视障人士感知事物,特别是颜色。作者已经开发了一个android手机应用程序,以原型方法使用手机的马达作为振动源,并绘制振动模式的颜色。随着移动电话的广泛使用,作者发现这种方法是设计应用程序以帮助视障人士学习过程的潜在解决方案。

IoT has become inevitable in current scenario of due to idea of smart living. Every aspect of human civilization is being converged to IoT systems, may it be smart homes, personal grooming, organization, smart city, health care, business, manufacturing, etc. IoT systems are not only contributing to improving the quality of service but also to effectively use resources. But, due to exposure of all sensitive data of a person/organization to the cyber community through IoT systems, which majorly exploits cloud platforms for implementing them, the people and organization are at more risk, and no. of cyber-crimes are also increasing day by day. Cyber-crime investigation involves digital forensic which is a typical task for IoT environments due to its heterogeneous nature. This work compiles a survey done on the current developments in the field of IoT forensic and tried to identify gaps, challenges, and scope of research in the field.
由于智能生活的理念,物联网在当前的场景中已经成为必然。人类文明的方方面面都在向物联网系统融合,可能是智能家居、个人美容、组织、智慧城市、医疗保健、商业、制造业等。物联网系统不仅有助于提高服务质量,还有助于有效利用资源。但是,由于通过物联网系统将个人/组织的所有敏感数据暴露给网络社区,而物联网系统主要利用云平台来实施这些数据,因此个人和组织面临更大的风险。网络犯罪也日益增多。网络犯罪调查涉及数字取证,由于其异构性,这是物联网环境的典型任务。这项工作汇编了一项关于物联网取证领域当前发展的调查,并试图确定该领域的差距、挑战和研究范围。

This study explores a supervised deep learning fully convolutional segmentation model for photovoltaic solar array mapping from aerial imagery. The deep learning imaging techniques present a fast and an inexpensive way for detecting distributed photovoltaic arrays installed on ground and building rooftops. The identification of correct photovoltaic array shapes and sizes is a necessary requirement for the estimation of energy from photovoltaic arrays within an area or city. This study proposes a modified and efficient UNet deep learning segmentation model by using depthwise-separable convolution for automated photovoltaic array detection from orthorectified RGB imagery with a resolution of less or equal to 0.3m. The result shows our model has better segmentation accuracy than various state of the art models and other previous studies on solar panel detection and is efficient in terms of parameters and complexity.
本研究探索了一种监督深度学习的全卷积分割模型,用于从航空图像中绘制光伏太阳能电池阵列。深度学习成像技术为检测安装在地面和建筑屋顶上的分布式光伏阵列提供了一种快速而廉价的方法。识别正确的光伏阵列形状和尺寸是估算一个地区或城市内光伏阵列能量的必要要求。本文提出了一种基于深度可分卷积的改进的UNet深度学习分割模型,用于分辨率小于等于0.3m的正校正RGB图像的光伏阵列自动检测。结果表明,该模型的分割精度优于现有的各种模型和其他太阳能电池板检测研究,并且在参数和复杂度方面是有效的。

In 2019, India recorded an overall 4,05,861 cases of crime against women, it was a rise of 7% from 2018. In 2019 total of 32,033 cases of rape were lodged, which was 7.3% of all crimes against women [18]. Data shows that the crime rate registered per lakh women population increased from 58.8 in 2018 to 62.4 in 2019 [18] [20]. There are many problems like sexual harassment, domestic violence, eve-teasing that are being faced by women. Sometimes victims don't have proof to prove to mishappen [20]. We proposed a device which will send an SMS to the registered mobile numbers when a button is pressed or when the women fall and save voice recording of that situation as proof. There are two separate parts in our proposed model, first is a transmitter which will be on the wrist and the other is a receiver part which contains Arduino UNO interfaced with SIM900A GSM module, NEO6M GPS module [15], RF TRANSMITTER AND RECEIVER module, BUZZER, MPU6050 (accelerometer) and ISD1820 (voice recorder) which will be fit on the jacket. When either a button is pressed from transmitter or MPU6050 (accelerometer) detects any fall, second part got activated and an emergency message will be sent with the current latitude and longitude, the buzzer will make a loud sound to get the attention of nearby people for quick help and ISD1820 (voice recorder) start recording voice as a proof.
2019年,印度共记录了405861起针对女性的犯罪案件,比2018年上升了7%。2019年,印度共发生32033起强奸案,占所有针对妇女的犯罪的7.3%。数据显示,每10万妇女登记的犯罪率从2018年的58.8上升到2019年的62.4。女性面临着许多问题,比如性骚扰、家庭暴力、嘲笑。有时受害者没有证据来证明自己的过错。我们提出了一种设备,当按下按钮或女性摔倒时,它会向注册的手机号码发送短信,并保存该情况的语音记录作为证据。在我们提出的模型中有两个独立的部分,首先是将在手腕上的发射器,另一个是接收器部分,其中包含Arduino UNO接口,SIM900A GSM模块,NEO6M GPS模块[15],RF发射器和接收器模块,蜂鸣器,MPU6050(加速度计)和ISD1820(录音机),将安装在夹克上。当从发射机按下一个按钮或MPU6050(加速度计)检测到任何跌倒时,第二部分被激活,并发送紧急消息与当前的纬度和经度,蜂鸣器会发出响亮的声音,以引起附近的人的注意,以便快速帮助,ISD1820(录音机)开始录音作为证据。
