In this paper, we explore the design and operations of an inter-satellite data relay network, which includes Low Earth Orbit (LEO), Medium Earth Orbit (MEO), and Geo-stationary Orbit (GEO) satellites. Due to the different orbiting speeds and dynamic behaviors of these satellite constellations, we consider Delay-Tolerant Networking (DTN) between them and implement contact graph routing (CGR) at the layer-3 and Licklider Transmission Protocol (LTP) at layer-4. We base our analysis on a realistic space scenario where satellite locations and movements over time are extracted from a real-time satellite database. We demonstrate end-to-end latency and goodput of a file transfer through the satellite network under consideration.

DevOps has become one of the most important ways for enterprises to succeed. Enterprises use DevOps to integrate and optimize procedures, such as agile development management, continuous integration, continuous delivery, technical operation, application design, security and risk management (DevSecOps), system and tool construction, monitoring state, and quality assurance. This greatly accelerates the delivery of high-quality software products to users. Combined with agile, lean management, and continuous delivery, this approach has been reconstructing the way to effectively develop cloud service and tryout hypothesis safely. Firstly, the flow through the lifecycle, which is divided into plan, design, code, build, test, release, deploy, and operate, should be identified and accelerated by automated test and CI/CD. Then, measurement should be integrated into each part of the flow, and the monitoring system should provide instant feedback. Quality assurance covers the entire life cycle of development and operation, which is beneficial for identifying defects at an earlier stage and preventing downstream problems.

The Physics-informed Neural Networks Deep Learning (PINN) framework has been introduced with the primary objective of advancing the field of blood flow simulations. PINN Deep Learning involves data-driven training for flow prediction and can incorporate the understanding of physical laws described by partial differential equations (PDEs). This paper employs the PINN Method for simulating blood flows. Multiple test cases will be computed and compared with other numerical and experimental results to validate the approach. The results demonstrate that the PINN method functions as expected, and validation against experimental and other researchers' results ensures the generation of meaningful output data and the prudent selection of parameters.

A patch array antenna working in the D-band is proposed in TSMC's 180 nm CMOS. The antenna structure applies a top metal layer (Metal6) as the patch antenna and a bottom metal layer (Metall) for the ground. Simulation results demonstrate that the on-chip patch antenna has a peak gain of - 5.95 dBi at 141 GHz. The measurement of the proposed antenna demonstrates bandwidth from 140 GHz to 202.5 GHz. The array on-chip patch antenna proposed can use in Smart cities technology and automotive applications.

This research aimed to deepen our understanding of the issues and challenges faced by beneficiaries of the Philippines' Universal Access to Quality Tertiary Education (UAQTE) program by utilizing Latent Dirichlet Allocation (LDA) complemented by Bag of Words (BoW) and Term Frequency-Inverse Document Frequency (TF -IDF) techniques. The study used the “Boses Ko” participatory toolkit, a digital portal to collect student responses from the various Higher Education Institutions (HEIs). The analysis showcased the LDA model's proficiency in identifying distinct clusters, underscoring its ability to generate coherent and meaningful topics that provide interpretable and insightful dataset representations. Evaluation of the models included Silhouette and Coherence Scores, supplemented by manual assessments by domain experts. This comprehensive approach led to the identification of key themes, including “Academic Difficulties,” “Financial Difficulties,” “Pandemic-Related Challenges,” “Grant Disbursement,” and “Program Implementation.” The identified themes present actionable policy recommendations geared towards strengthening academic support, financial assistance, flexible grant disbursement, addressing pandemic-related challenges, and establishing a structured feedback mechanism. These measures collectively aim to enhance the overall implementation of the UAQTE program.
