In the modern times, PA uses a large number of sensors in a networked architecture to collect the information on the exact needs of the plants and their productivities. With the arrival of Internet of things (IoT), now PA can be implemented quite systematically. Undoubtedly, agriculture is one of the most important economic sectors of the world. For the developing countries, it is an essential sector. Agriculture is directly associated with the daily needs of human being such as food, clothing, and shelter. In the recent years, developing countries are facing a lot of difficulties in the agriculture related aspects such as lack of water for irrigation, desertification of fertile land, and reduction in harvests. PA can ease these problems through the use of IoT based applications. In this paper, we provide the recent frameworks of PA using IoT. We show how it can help the agricultural sectors of the developing countries in the long term.

A large number of machines, devices and people are connected with each other through different communication frameworks. Since the data is huge in amount and takes a large storage space, it is named as big data. Such big amount data cannot be analyzed using the traditional methods of data analysis. Big data analysis needs new methods and approaches to handle their complexities. Numerous methods have been developed in the recent years to process this large amount of data. The data can be stored in cloud anytime and can also be retrieved from cloud anytime based on the requirements. As an alternative for data analysis and computing various attempts have been made using new tools. Augmented reality (AR) is an extended feature of virtual reality and it is helpful in visualizing huge amount of data obtained from heterogeneous sectors in a simpler manner. There are a few digitized tools available these days with the help of which process of visualization can be made faster. The scheme of convergence of both the tools (i.e., big data and AR) results in productive applications that are better than a few of existing technologies. This article provides a detailed study on big data, AR, and the utilities of big data using AR. Also, this research work has gone through the foreseeable future scopes and the main issues and challenges associated with AR based big data analysis.

The waveforms proposed for 5G are very much different from those of 4G and 4.5G. It is primarily due to the existing demerits of the 4G/4.5G waveforms. There are also several additional reasons why 5G should have new waveforms. Energy efficiency of 5G technologies are intended to be exemplary. In this paper, we discuss the proposed 5G waveforms and their energy efficiency issues. We compare their overall efficacy in the cellular ambient environments.

Feeding system plays an important role to increase the number of bands(3).One of the original excitation methods for the microstrip patch antenna is edge fed or microstrip line fed technique. The proposed antenna structure consist of a I-shaped microstrip feed line and open slots of very small size in ground. Offset Feed increases overall performance of antenna to fulfill requirements of multiband communication. Further relationship of slots cut in ground to bandwidth performance has been analyzed.

Due to multiresolution decomposition, diagnostically important clinical components are grossly segmented at different scales. If multiscale multivariate matrices are formed using all ECG leads and subjected to covariance analysis at wavelet scales, covariances change from normal as MI evolves. This is due to the underlying pathology which is seen in few ECG leads. To capture the changes that occur during infarction, multiscale multivariate distortion metric is applied on covariance structures. To evaluate the proposed method, data sets are adopted from PTB diagnostic ECG database. This includes healthy control (HC), myocardial infarction in early stage (MIES), and acute myocardial infarction (AMI). The results show that the proposed method can detect the pathological MI subjects. For MI detection, the accuracy, the sensitivity, and the specificity is...

Hence, colour change has been considered as an important quality trait to assess ripening behaviour of tomato fruits. Present study depicts the use of two widely used colour based parameters for assessment of ripening behaviour of tomato fruits during storage. Tomato fruits of ten popular Indian varieties were harvested at green mature stage and stored up to 14 days at 22 ± 1°C with RH of 90 ± 5%. Ripening index (RI %) and red tomato (RT %) were used to determine the progress of ripening at 5, 10 and 14 days after harvest. Out of these two parameters, RI (%) was found to be better for assessment of tomato fruit ripening as it was more sensitive (2.5 times) to the change in rate of ripening than the RT (%). Hence, this colour change based simple, rapid and non-destructive parameter can be used suitably for assessing the progress of tomato fruit ripening. Based on the time-course values of RI (%), tomato varieties were classified as fast ripening, intermediate ripening and slow ripening types. Further, visual colour based evaluation of tomato fruits is discussed and its implications are being highlighted for other colour associated and ripening-related changes (maturity, firmness, nutritional status).

Starting from the data rates, to the latency, to the overall coverage, in every aspect it is far beyond its predecessor, 4G. In addition to provide all these advanced features, the 5G network will not be completely wireless. Rather it will be a hybrid of both optical and wireless networks. In this paper, we present the main reasons why such a hybrid system is required and also provide its architectures.
