Farm Fusion is a cutting-edge agricultural solution that improves management and resource efficiency. Farm Fusion combines cutting-edge technologies to monitor and maintain ideal farming conditions. The system monitors agricultural irrigation needs using sensors for soil moisture and water level, and automatically activates water pumps to correct for shortfalls. Farm Fusion uses a 2D camera to detect and identify wild animals, protecting farmers' crops from potential threats. This multimodal method optimizes water use, manages wildlife efficiently, and promotes sustainable farming techniques.

Small steerable reflector antennas are of prime importance on scientific satellites to transmit the experimental data towards the ground station. However, achieving higher efficiency and having minimum dynamic envelop during the rotation is a challenging task. In this paper, design of a reflector with diameter 28λ at X-band in Axially Displaced Ellipsoid (ADE) geometry is illustrated. It is experimentally demonstrated that the antenna can provide an aperture efficiency of more than 70% which is significant especially considering the small diameter of the reflector. This efficiency has been achieved by proper choice of design parameters and material used. Thermo-plastic based struts are used to support sub-reflector from the feed.

In this paper, a light weight, dual linearly polarized stacked microstrip reflectarray antenna for Ku-Band satellite on-orbit telemetry, tracking and commanding (TT&C) application that can be placed on Earth Viewing (EV) side of GEO satellite is presented. Unit element that will suit both downlink and uplink frequencies which are separated by ratio of 1.15 is chosen and reflectarray is generated based on optimal phase value compensation technique. Simulated peak gain of 26.7 dB is achieved for downlink frequency with cross polarization of 28 dB. At uplink frequency, simulated peak gain of 27.3 dB is achieved with cross polarization of 28 dB.

This paper explains about a compact multiband single arm Archimedean spiral antenna with taper feed. The antenna is designed on a 1.57mm thick Roger’s RT Duroid 5880 substrate and it operates at 1.24GHz, 1.76GHz, 2.43GHz, 3.29GHz, 5.8Ghz with good impedance matching, Gain and Radiation pattern characteristics. The antenna would be very promising for vehicular communications which involve navigational wireless frequencies, wireless communication frequencies and dedicated short range communication frequency.

Social media is an online platform where users freely share their views on various topics. By sharing their views, they come to a mutual agreement or disagreement with other users’ views. Users are quite active on social media and the number of users is growing exponentially with time. This leads to an abundance of data available through social media. This data helps us in curating different research problems. One such research problem can be finding similarities between users by analyzing user data. Data on social media is available in many forms like textual posts, comments, likes, shares, etc. Users often tend to express their diversity of opinions widely through comments on social media. Many opinionated and active users on social media are found in the comments section under a post. Hence, comments play a major role in determining similarity in user judgment about a topic. Likewise, people liking a post is also an essential feature in finding similarities between users. People with similar opinions tend to like posts of a specific type. This paper talks about how comments, textual posts, and likes for comments can be combined to form something called a keyword or a tag. These tags that are extracted from user data are further used in building a tag network. The tag network is used to make communities of users with similar interests. User grouping can also be done based on these extracted tags and comments under the posts. The proposed methods in this paper to achieve the above-mentioned are TF-IDF (Term frequency-inverse document frequency) followed by the TextRank algorithm.
Printed leaky-wave antenna with stable gain and reduced cross polarization
Birendra Kumar, Jayanta Ghosh
Microwave and Optical Technology Letters, 2022
A printed leaky‐wave antenna with stable gain and reduced cross‐polarization level is presented in this letter. The proposed antenna has the property of continuous backward‐to‐forward beam scanning with symmetrical scanning. The proposed antenna's unit cell consists of two unequal inclined stubs connected to a microstrip line. The angle between the stubs and their dimensions is designed optimally to obtain improved antenna performance. The antenna provides stable gain with peak gain 14.4 dBi and gain variation 2.55 dBi in the operating band 9.5–15 GHz. The maximum value of cross‐polarization level along the main beam is −30 dB. The design gives a scanning angle of 73° from −36° to +37° through broadside. Another important feature of the proposed antenna is that there is no gain reduction at the broadside radiation.

Designing a dual-band circularly polarized planar array with good isolation between the two bands is a complex job. In this work this has been implemented using a novel approach of interleaving the radiating elements of both the bands over a common aperture and yet keeping the inter-element spacing within the acceptable limits. The design has been carried out at Extended C-Band to meet the objective of achieving a half power beamwidth of 5° within the constraints of minimum mass and volume. The hardware has been successfully realized and the measured return loss is better than 20dB and the isolation between the two ports is better than 30dB at the required frequencies.
