Optimization is the process of achieving and maintaining the required quality as designed by addressing deviations between radio network planning and real-world implementation. It involves tuning antenna parameters, radio frequencies, and neighbor lists to improve coverage, call and handover quality based on drive test results and key performance metrics. The optimization process occurs in initial, primary, and maintenance phases and utilizes tools like drive test kits and optimization software to analyze problems, identify solutions, and fine-tune the network over time.

The document discusses CSU's underground electric distribution asset management program. It notes that over 50% of CSU's system is underground, which can increase reliability but also cause lengthy outages if equipment fails. The objectives of the asset management program are to inspect, refurbish, and replace padmount transformers and switchgear on a systematic schedule to maximize reliability and minimize costs. The process involves dividing the system into zones, inspecting equipment for issues like corrosion each year, then refurbishing or replacing based on condition. Annual inspections have identified needed design improvements. The goal is to inspect all assets on a 10-year cycle to manage the over 4,000 underground components reliably and cost-effectively.Milestone checklist

Mobile Ad Hoc Network (MANET) is a self-organizing and flexible system. MANET systems manage sensitive data from many distinct applications in various domains. Its dynamic nature increases its vulnerability to numerous types of security threats. Many of the present approaches using indirect approaches provide false approximations of trust degrees. It is significantly required a good routing system that meets Quality of Service (QoS) standards and enhances network performance. In this paper purposed cluster-based trustworthy safe multipath routing (CTSMP-Routing) for mobile ad hoc networks (MANETs). Load balancing challenge is addressed by using a modified proportional topology optimization (MPTO) approach using geographical data related to network nodes. The Enhanced Seeker Search Optimization (ESSO) approach is used to compute trust degrees after the clustering phase considering numerous network constraints including node mobility, received signal strength, energy consumption, and cooperation rate. Assumed to be the service node, the node showing the highest degree of trust manages inter-cluster routing. We have developed a hybrid soft computing approach termed the multi-layer deep recurrent neural network (ML-DRNN) to enhance the optimal path-finding process. This method selects, among many routes between source and destination nodes, the best one quickly. The outcomes of this paper demonstrate that CTSMP-Routing provides effective protection against several attack paths within the MANET environment and displays better performance in regard to quality of service (QoS) requirements.Abraham Silberschatz-Operating System Concepts (9th,2012.12).pdf

This covers how image processing or the field of computer vision has advanced with the advent of neural network architectures ranging from LeNet to Vision transformers. It covers how deep neural network architectures have developed step-by-step from the popular CNNs to ViTs. CNNs and its variants along with their features are described. Vision transformers are introduced and compared with CNNs. It also shows how an image is processed to be given as input to the vision transformer. It give the applications of computer vision.ElysiumPro Company Profile 2025-2026.pdf
