DNN Design for Object Detection in Airport Runway Operations
In this project, we attempted to solve the problem of object detection in airport runway environments by leveraging DNNs. The DNN model developed will be able to classify objects and also accurately localize objects of different classes. The major aspect here is the task of object detection is going to be considered as a regression problem to object bounding box masks. It would be a multi-scale inference procedure that can generate high-resolution object detection at a minimal cost. Here we were able to test our custom dataset on three object detection models. The models considered were (1) Faster-RCNN with VGG-16, (2) YOLOv3 with darknet53, and (3) SSD Inception V2(coco) from the TensorFlow object detection API. All the above algorithms were trained using the Tensorflow framework. The paper gives a brief comparison in the performance of the above-mentioned algorithms when trained and tested while keeping the main goal to be object detection in airport runways. We trained the YOLOv3 with darknet53 on our custom dataset and were able to obtain the classifier accuracy for the bounding boxes to be 74.00% which was the best of the three algorithms and has outperformed many previous works. The YOLOv3 could be considered a fast training algorithm when the model is trained on a powerful GPU and could play a major role in the field in terms of real-time object detection scenarios.

Optimum design of a 100-meter high meteorological mast
Meteorological mast (met mast) is a tower-like structure in which wind resource measuring equipment is installed with an objective to estimate the wind power potential of the region of interest. Met mast can be either be a self-supporting tower or guy supported tower. In this study, the analysis and design of guyed steel lattice met mast of 100m height is carried out using STAAD. Pro software. The towers are modeled using base configuration triangular. As stated in IS 800-2007, in addition to the self-weight, the wind forces are predominant on the tower and guy wires. This study focuses on optimizing the met mast using the 'X' bracings, and Static analysis is performed by varying the sections. The usage of 'X' bracing for the structure has resulted in the significant structure's weight reduction. The appropriate levels of guy wire anchoring positions and the optimum guy wire diameter are chosen using preliminary analysis. Towers are modeled using different section shapes viz. tubular section and pipe section, and finally, an optimum section shape has arrived. The towers are analyzed under various load combinations as given in IS 875 (part 3:2015), IEC 61400-12-1 standards, Meanest standards, etc., and designed considering the provisions provided in IS 800-2007. The results are correlated and finally, an optimum design has arrived.

Herbs and copper effect on physical properties of water
The present experiment is to study the effect of Tulasi, kusha, and copper on the Physical properties of water. In the study, commonly growing Tulasi (basil), and dry kusha, and the commercially available copper wire were used. Tulasi, kusha, and copper with a weight of 100 mg, 250 mg, and 500 mg were used. Materials were immersed in the glasses with 100 ml water and conductivity, turbidity, and pH of the water was measured at the time duration of immediate, two hours, four hours, six hours, and 24 hr. The Experiment conducted for five trials with three replications each and a total of 15 numbers. Kruskal-Wallis test was applied to assess changes between groups in all variables. Tulasi and copper decrease conductivity and turbidity of water irrespective of their weight while there was an exponential significant increase of these properties of water by kusha with the direct relation of its weight during all the duration of time. Tulasi, kusha, and copper decrease the pH of water for all the duration of time, and this decreasing trend is more by increasing their weight. Tulasi and copper decrease conductivity and turbidity of water while kusha increases these properties. All these materials decrease the pH of water during all the duration of time and this decreasing trend is more by increasing their weight.

Newspaper reading habits among the primary school teachers in Mysore city, Karnataka
As a human being to know a new idea, innovative knowledge and learning process in day to day life and to learn continuously one of the paths are print and electronic versions of the newspaper. The study was conducted to investigates the newspaper reading habits among the primary school teachers in Mysore City, Karnataka. The study highlights the time spent in reading newspapers, the preference of language, the purpose of reading newspaper, the reason for reading newspaper, the preferred format of newspapers, newspapers source, and names of the newspaper preferred by the teachers. The interview and questionnaire method was used for the present study to collect the necessary data and the collected data has been analyzed and presented in the form of tables. The appropriate suggestions are provided for further improvements in newspaper reading habits of primary school teachers.

Not information centers, but information generation centers
Academic libraries are in a changing stage. The academic community is more aware of the advanced digital technologies and they like to have the information retrieval using these advanced technologies. The library users are in need of the information new in style, new in fervor, and new in the method. The librarians in the digital environment have to be aware of online platforms, audio, and video uploading, databases, networking, and computer terminals. The influence that occurred due to this digital wave in the production, dissemination and retrieval of information may grasp the academic libraries to satisfy their information seekers in pursuing new modes of academic research and productivity. Digital libraries need very little physical space and they can occupy more information. Moreover that in the digital system the information seekers can rapidly and easily access books or any other information sources. The library has a specific role to create information using different types of media. Informative videos, slides, different types of arts and entertainment programs can be generated and uploaded using advanced digital technologies.

A study on current diagnostic approaches to Covid-19
The unanticipated outbreak of the novel coronavirus later identified as Severe Acute Respiratory Syndrome Coronavirus 2(SARS-CoV-2) has rendered the world speechless. After only two and a half months since the first case was reported in the Wuhan city of China, the WHO declared the coronavirus disease a pandemic. So far the virus has covered all 196 countries infecting millions. Scientists all over the world are putting in all their resources to formulate a vaccine to put an end to this pandemic. Meanwhile, prevention remains the only option. It is necessary to contain the disease to slow down its spread rate and for that fast and accurate diagnosis is vital. This review summarizes the current approaches for the diagnosis of the coronavirus disease. They are categorized based on their target molecule (RNA, antigens, or antibodies). We have also shed light on some newly emerging rapid testing techniques using chest scans and biosensors for high specificity to get more accurate results. The use of any one of them depends upon the severity of the case. At times more than one technique is used to get a sure outcome. Culture-based virus detection in the lab act as the gold standard of accuracy for all of these techniques. The study of the underlying mechanism of these techniques also helps to understand the virulent behavior of the virus and its mode of action. Taking into consideration all of these approaches, each one has its limitation that is also discussed in this article.
