The advancement of Information Technology has made cloud computing technology an innovative model for offering its consumers services on a rental basis at any time or location. Numerous firms converted to cloud technology by establishing new data centers because of the flexibility of cloud services. However, it has become necessary to ensure successful job execution and effective resource usage. Load balancing (LB) in cloud computing remains a complex challenge, specifically in the Infrastructure as a Service (IaaS) cloud architecture. A server being overloaded or underloaded is a problem that mustn’t happen in the process of cloud access because it would slow down processing or causes a system crash. Hence, to ignore these problems, a suitable resource schedule must be taken, so that system can load balance tasks over all accessible assists. This research suggests effective load-balancing approaches by analyzing the advantages, applications, and disadvantages of conventional LB techniques. The conclusions show that this research provides an exceptional path for researchers to overcome major drawbacks of existing LB techniques and achieves greater efficiency based on makespan, execution and response time, resource usage, efficiency, load balancing and throughput.

This paper presents a new single-stage isolated bidirectional stacked switches-based CLLC resonant converter with reduced storage capacitances for High Voltage (HV) Electric Vehicle (EV) systems. In the proposed converter, two closed-loop ripple reduction control units implemented on both rectifier and inverter modes of the converter to minimize the output and DC-link voltage ripples without any additional circuit design. As a result, the bulky unreliable electrolytic-type DC-link and output filter capacitors are replaced with significantly smaller and more reliable ceramic capacitors. Moreover, a closed-loop duty ratio controller guarantees a high-quality sinusoidal input current in the rectifier mode, while output voltage regulation is realized using Variable Frequency Modulation (VFM) technique. In inverter mode, a Second Order Generalized Integrator (SOGI) Phase Lock Loop (PLL) along with a fixed-band Hysteresis Current Controller (HCC) is implemented for power transfer from the EV to the grid, making the converter robust against frequency disturbances. The converter’s performance is verified through a 1kW, 120Vrms/800Vdc design.

Blockchain technology is becoming a great innovation at today's date due to its transparency, security and reliability. With the advancement in every aspect of life blockchain with its decentralized and distributed ledger system aims to provide immutability in digital transaction across the globe with the help of block structure joined together that stored the data in the form of hash. The data stored in block is next to immutable as if tried to change in a single block the hash of every block in the chain will change which makes it easy to identify. Due to its security and transparency the study describes its use in the e-voting system revolutionizing voting system with more security and transparency reducing logistic problem, solving storage issues, solves the problem of using extra man power in the large democracy like India.

Peer instruction is instructional in guiding students to learn by answering questions, and explaining and discussing their answers with peers. Researchers recommended asking students to write down their answers and explanations before discussion to prevent social loafing. In addition, text-based explanations can be recorded and analyzed. The quality of students’ explanations varies, ranging from superficial and low-quality to detailed and in-depth high-quality explanations. In tradition, the qualities of students’ explanations were assessed by experts. Recently, machine learning classification models have been developed and applied to classify texts. However, the level of explanations of questions are question-dependent. Thus, each question needs its classification model. Therefore, a feature transformation was applied in this study so that the explanations of different questions could be combined and applied to train the same classification model. An automated explanation quality assessment mechanism was developed based on the similarity of representative explanations of different qualities. Students’ text-based explanations were collected and assessed by experts into four levels, ranging from 0 (worst) to 3 (best). The four-level classifications were merged into binary classifications of low (0 and 1) and high (2 and 3). Different classification models, including Support Vector Machine (SVM), Naive Bayes (NB), K Nearest Neighbor (KNN), Logistic Regression (LR), Random Forest (RF), and Bidirectional Encoder Representations from Transformers (BERT) were applied to train models and evaluate the accuracy of the models. In addition, three ensemble learning algorithms, including voting, stacking, and boosting, were applied to combine models chosen from SVM, NB, KNN, LR, and RF. The results showed that RF and RF+KNN+NB with stacking model showed the best accuracy (75.3%) among all four-level classification models whereas RF with boosting model showed the best accuracy (9

Anxiety disorders are widespread and significantly impact daily life, necessitating accurate and timely assessment for effective intervention. Traditional methods of anxiety evaluation are often subjective and time-consuming. This study introduces a deep neural network (DNN) model with L2 regularization designed to classify anxiety into four categories: low, moderate, high, and no. For stable learning, the model employs batch normalization, dropout for regularization, and hidden layers with rectified linear unit (Re functions. Trained on a diverse Kaggle dataset, which includes psychological and physiological features, the DNN achieves a remarkable classification accuracy of 92%. Anxiety evaluations may be automated using deep learning techniques, as demonstrated in this paper, providing mental health professionals with an effective tool for developing customized treatment programs. By adding more data sources, future research attempts to improve the model's predicted accuracy and scalability, thereby advancing automated anxiety assessment in clinical settings.

White blood cells, also known as leukocytes, or WBCs, spread abnormally in the bone marrow and blood, resulting in leukaemia (blood cancer). Leukaemia can be identified by pathologists by examining a patient's blood sample under a microscope. By counting different blood cells and physical characteristics, they can identify and classify leukaemia. This method takes a lot of time to forecast leukaemia. The pathologist's professional qualifications and experiences may also have an impact on this process. Traditional machine learning and deep learning techniques in computer vision are useful road maps that improve the precision and speed of identifying and categorizing medical images, such as minuscule blood cells. This paper offers a thorough analysis of the different Deep CNN models for identification and classification of WBCs and acute leukaemia in microscopic blood cells.

Event camera has recently received much attention for low-light image enhancement (LIE) thanks to their distinct advantages, such as high dynamic range. However, current research is prohibitively restricted by the lack of large-scale, real-world, and spatial-temporally aligned event-image datasets. To this end, we propose a real-world (indoor and outdoor) dataset comprising over 30K pairs of images and events under both low and normal illumination conditions. To achieve this, we utilize a robotic arm that traces a consistent non-linear trajectory to curate the dataset with spatial alignment precision under 0.03mm. We then introduce a matching alignment strategy, rendering 90% of our dataset with errors less than 0.01s. Based on the dataset, we propose a novel event-guided LIE approach, called EvLight, towards robust performance in real-world low-light scenes. Specifically, we first design the multiscale holistic fusion branch to extract holistic structural and textural information from both events and images. To ensure robustness against variations in the regional illumination and noise, we then introduce a Signal-to-Noise-Ratio (SNR)-guided regional feature selection to selectively fuse features of images from regions with high SNR and enhance those with low SNR by extracting regional structure information from events. Extensive experiments on our dataset and the synthetic SDSD dataset demonstrate our EvLight significantly surpasses the frame-based methods, e.g., [4] by 1.14 dB and 2.62 dB, respectively.
