Twenty-first century is an era of cutting-edge technologies. From artificial intelligence to nanotechnology, modern life has gathered the pace to match up with the shrinking time and fast-moving world. Likewise, a Heterogeneous Network finds its own space in this century of inventions. Every individual, industry, and institute needs to be connected to the internet cloud. Mobile applications have changed the dynamics of every individual’s life. From personal management to professional proficiency, mobile applications play an important role in almost every aspect. Numerous applications available these days demand continuous bandwidth connection. To remain always connected, there is a need for an effective handoff procedure. In this paper, we have proposed a convex optimization technique for optimizing the call drop probability, remaining energy and handoffs in heterogeneous networks. The proposed algorithm outperformed the already existing M-OPTG and M-WO algorithms.

Today technology is so advanced we can store thousands of books in a few gigabytes of memory. An enormous amount of information is also available on the Internet. But greater access to a massive amount of information is only worthwhile if we read the relevant material. That is why we must underline developing reading habits for our students. Students also need to comprehend and critically think about what they read from the books and other resources. Real learning ensues only then. When the students become good learners and remain life-long learners, that reflects the quality of education provided to them. Quality in Education is accomplished when students are motivated to accumulate adequate knowledge and skills and can proficiently utilize these tools to find pragmatic solutions to pressing challenges in their lives and careers.

Partially shaded panels lead to the creation of troughs in the power generation PV curve, from its optimal potential. Researchers have focally went through for findings in the optimal Photo Voltaic (PV) configuration namely Series (S), Parallel (P), Series–Parallel (SP), Bridge Link (BL), Honey Comb (HC), Total Cross Tie (TCT), Triple Tied Cross Link (TTCL), and Hybrid Configurations. In this paper, a Novel Double Tied Cross Link (DTCL)-based PV panel configuration is proposed. The superiority of the proposed DTCL configuration is that the number of local maximum power points (LMPP) is reduced in certain partial shaded conditions and optimized cost also possible, as the number of cross-links has been reduced, compared to conventional configurations. The maximum power generation superiority of TCT and TTCL has been realized with the proposed novel configuration of Double Tied Cross Link. Using MATLAB/Simulink, different patterns of possible shadings have been created as a replica of real-time partial shadings. Analysis of the proposed DTCL configuration has been implemented along with the conventional configurations in MATLAB simulation. The technical parameters, such as open circuit voltage, short circuit current, maximum voltage, maximum current, fill factor, mismatch losses, and efficiency, are considered for analyzing the proposed DTCL photo voltaic configuration. Besides, this article also presents a novel DTCL PV configuration which reveals cross-cable savings, maximum power attainment, and economically feasible, as usage of cross cables is less, without much compromising on power generation.

A novel Single-shot Multi-scale detection network with feature fusion and multi-scale attention mechanism is proposed for autonomous driving. The proposed model is referred to as a Single-shot Multi-scale Attentive Detector (SSAD) and it would build feature relations of the feature map in the spatial space. The proposed network highlights pedestrian and vehicle regions on the extracted feature map and also suppresses irrelevant regions, from the global relation information and thereby providing reliable guidance for autonomous driving, while detecting smaller and occluded targets. SSAD design is simple, accurate and computationally efficient. Evaluation results of the proposed network on multiple datasets have achieved considerable and promising results. Experimental results show that the SSAD network when tested on Pascal Voc-2007, INRIA, Caltech, and City Persons datasets, outperforms many state-of-the-art (SOTA) detectors.

Ant Colony Optimization (ACO) is an algorithm based on Meta-heuristics and swarm intelligence, taking inspiration from the exploring behavior of social insects like ants. Some very challenging optimization problems, like the vehicle routing problem, have been solved by Ant colony optimization. But, the Standard ACO algorithm has problems like trapping in local optimum. This paper discusses an improved version of the ACO algorithm, known as Modified ACO (M-ACO). The main motivation of the proposed algorithm is to use pheromone mutation techniques, such as swap and random, in dynamic environments, to overcome the problems of standard ACO and solve the Travelling Salesman Problem, which is a well-known NP-hard problem. Mutation allows better searching and exploring in other areas, for better results. Also, the exploitation is increased that uses local information to search local regions more intensively for finding minimum distance and increasing the rate of convergence. Evaporation-based Ant colony optimization (E-ACO) framework and population-based ant colony optimization (P-ACO) framework are the two groups into which the algorithms under study are separated. Both frameworks are evaluated on dynamic environments produced using TSPLIB base instances and updated for pheromone values using mutation technique. Experiments and Statistical tests were conducted on the TSPLIB datasets such as pr439 and lin318, in dynamic environments and on comparing ACO with M-ACO and P-ACO, better results were obtained for M-ACO and P-ACO. Metrics like offline have been considered to measure algorithm performance and behavior.

In this work, we consider the problem of tonic note selection and voice range determination for Indian music singers. A tonic note is a reference note of a singer that decides the pitches of the other notes used by the singer. The ratios of various notes to the tonic note are fixed by the scale used by the singer. A novel graphical method for tonic note selection is proposed. In this method, tristimulus diagrams are used to represent notes in the Aroh and Avroh. The notes are represented by a point in the tristimulus diagram. The locations of the notes in the tristimulus diagram represent their perceptual attributes. The tristimulus diagram is divided into grey and white areas. The notes going in the grey area are designated as perceptually inferior and accordingly, a tonic note is suggested such that all the notes remain in the white region of the tristimulus diagrams. As compared to state-of-the-art, the proposed method is more convenient to use.
