the heart is one of the most essential organs in the human body, working as the major pump for the blood that passes through the veins of the body, transporting energy and nutrients needed for the body to function. However, even though it is also one of the most protected organs in a human body, it is not exactly free from threats like diseases, malfunctions, etc. as it can still be damaged by various factors. As such, this research was made to detect the existence of heart diseases that might affect the functionality of the organ itself, by using various features to be used in an experiment where it involves multiple models with hyperparameter tuning with hyperparameters that we consider to be the best for each model used from our experiment in addition with experiment using LSTM and KNN in order to determine whether or not a patient has a cardiac condition. the experiment done by this research has gained quite a result, utilizing techniques like Hyperparameter optimization to find the best performing model, which was found to be tuned KNN with gain accuracy of 91.85%.

Text summarization is a natural language processing (NLP) technique in artificial intelligence that has been studied in recent years. Every document containing text is tested to get a good summary result. In producing a good summary, proper accuracy is required; therefore, various techniques and methods are used, and another challenge is the use of language in the documents being tested. Various types of documents have been used as research for text summarization, including scientific documents, so researchers are interested in studying them more intensely to get the state of the art in research. this research was conducted to review previous research using literature studies from various publications that published research on text summarization in scientific documents. the researcher collected data from several publishers who had published this type of research from 1988 to 2023 quarter 1 and obtained three hundred and eleven articles, then the researcher analyzed the data using the Kitchenham method to get the right literature to answer the research question. thirty-seven articles were selected for further in-depth analysis. In addition, the researcher found some interesting findings beyond the research question, including other techniques used to solve the text summarization problem and other types of output that are not commonly produced so that it can increase knowledge in researching text summarization.

the number theoretic transform (NTT) has made the computational process much faster in lattice-based postquantum cryptography algorithms, but polynomial multiplication is still the bottleneck of the process. RISC-V was introduced and demonstrated its advantages through flexibility in the instruction set architecture. this paper proposed a RISC-V SoC architecture with NTT-Blackbox that accelerates the computing capabilities of software programs running on SoCs, applied to the Kyber algorithm. the results show that the proposed architecture has improved speed from $71.5 \%$ to $\mathbf{99 . 3 \%}$ compared to software programs running on other RISC-V SoCs.

In order to solve the problems of low radiation power of microstrip antenna and difficult integration of metal waveguide, substrate integrated waveguide (SIW) structure withthe advantages of both microstrip and waveguide has attracted wide attention. Based on HFSS, an 8-element constant amplitude in-phase standing wave linear array operating at Ku-band withthe center frequency of 18GHz is designed by using the side-feed mode. then the 8×8 slot array antenna is designed by the wide side longitudinal slit of the SIW. the simulation results show that the gain of the array is 20.9dBi, the return loss is very small, the VSWR is less than 2 in 17.09~18.19GHz and 19.66~22 GHZ bands, and the relative bandwidth is about 59%.-10dB bandwidth is 17.18GHz-18.14GHz(16.6%). the resonant frequency of the input reflection coefficient is 18GHz, which is less than -20dB, and the antenna efficiency is high. the simulation results are good, which verifies the feasibility of the design. the designed antenna has high gain, strong directionality, easy integration and good impedance matching, which has a broad application prospect in microwave and millimeter wave systems.

Since the early 2020s, the world has grappled withthe COVID-19 pandemic, unleashed by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). the pressing need for swift and reliable diagnostic techniques became evident as this global crisis unfolded. While numerous approaches for early detection continue to evolve, the quest for innovative methods remains constant. In light of this, our research project aimed to develop and evaluate a highly efficient desktop application meticulously designed for a SARS-CoV-2 testing device based on electrochemical potentiostat principles. Our primary focus revolved around creating a user-friendly desktop application, seamlessly integrating an algorithm that automates result generation for operators. We successfully constructed the application by leveraging the robust Electron framework and employing HTML, CSS, and JavaScript languages. In addition to its exceptional performance, our application boasts an intuitive graphical user interface (GUI), enabling operators to familiarize themselves withthe system through concise training periods swiftly. By merging cutting-edge technology and user-centered design, our solution sets a new standard for efficient and accessible SARS-CoV-2 testing.

Denial-of-service attacks are always one of the most widespread security attacks at the enterprise network level. In DDOS attacks, a large amount of false demand is intentionally sent to the target network to disable the service. In DDoS attacks, the target server faces many demands, not from a specific source, but from different locations of the attack, which makes detection and defense more difficult. Withthe introduction of network functions virtualization and Software-defined networking , a new route, for network design and management, has been created. the purpose of this research is to investigate and compare DDoS attack defense methods using NFV and SDN. the details provided will help researchers in this field familiarize themselves with DDoS attack defense methods and choose the appropriate design for their actual implementations..
