Paper covers image classification using the Keras API in TensorFlow. The dataset used is a set of labelled images consisting of characters from the Pokémon media franchise. In order to artificially generate additional data, the process of data augmentation has been applied on the initial dataset to reduce overfitting. A comparison between DenseNet-121, DenseNet-169 and DenseNet-201 has been made to observe which of the models scores a greater accuracy. A Graphics Processing Unit (GPU) has been set up to work with TensorFlow in order to efficiently train the model.
论文涵盖了使用TensorFlow中的Keras API进行图像分类。使用的数据集是一组标记图像,由来自poksammon媒体特许经营的字符组成。为了人为地产生额外的数据,在初始数据集上应用了数据增强的过程,以减少过拟合。对DenseNet-121、DenseNet-169和DenseNet-201进行了比较,以观察哪一种模型得分更高。为了有效地训练模型,已经建立了一个图形处理单元(GPU)来与TensorFlow一起工作。

Maintaining and establishing transparency, security and privacy, when the data that should be included as part of documents that should serve as public educational documents in the labor market, are a challenging task, especially nowadays when we have more frequent cyber-attacks on public institutions. Setting up the security mechanisms of information systems that should store, process and show this type of data can be a very demanding job. For this reason, the introduction of new technologies in this area, such as blockchain technology, leads to considerable system and implementation relief. In this paper, private blockchain platforms are analyzed from the point of view of processing digital certificates or diplomas in the higher education system. An overview of the most popular platforms of this type is given. The most appropriate solution for these needs are discussed and proposed.

In this study we explore and systematically review the latest research on container orchestration architectures, models and methods and their application in cloud environments. The aim of our systematic mapping study is to identify, classify the existing research papers and thus give organized knowledge of this evolving area. We tried to establish a systematic methodology that ensures the validity of our secondary study and construct a classification scheme that helps derive useful information from the existing body of research. We’ve gained insights about specific technology related issues like container orchestrators and container runtimes but also knowledge about more generalizable aspects like research strategies and approaches used in the primary studies. The results gave us insights about the current state and maturity of the research area and helped us identify research gaps. We were able to formulate recommendations for future research.

As the demand for sustainable and renewable energy sources grows, the use photovoltaic (PV) systems have seen rise in popularity and recognition. The performance of PV systems is influenced by numerous factors such as solar irradiance, temperature, and the tilt angle of the PV modules. Among these factors, the tilt angle of the PV modules plays a crucial role in determining the amount of energy that can be generated by a PV system. This paper explores the impact of tilt angle on the output and performance of grid-connected PV systems by using the software PVsyst. The study will examine how different tilt angles affect the energy yield, electrical characteristics, and performance ratio of PV system. A study was conducted to compare the performance of a PV system with fixed tilt angle versus seasonal tilt arrangement. The results showed that a seasonal tilt arrangement led to improved performance and increased electricity generation.
随着对可持续和可再生能源需求的增长,光伏(PV)系统的使用越来越受欢迎和认可。光伏系统的性能受到许多因素的影响,如太阳辐照度、温度和光伏组件的倾斜角。在这些因素中,光伏组件的倾斜角度在决定光伏系统可以产生的能量方面起着至关重要的作用。本文利用软件PVsyst研究了倾斜角度对并网光伏系统输出和性能的影响。本研究将检视不同的倾斜角度如何影响光伏发电系统的发电量、电学特性及效能比。对固定倾角光伏系统与季节性倾角光伏系统的性能进行了比较研究。结果表明,季节性倾斜安排可以改善性能并增加发电量。

In this article, an upgraded version of CUDA-Quicksort - an iterative implementation of the quicksort algorithm suitable for highly parallel multicore graphics processors, is described and evaluated. Three key changes which lead to improved performance are proposed. The main goal was to provide an implementation with increased scalability with the size of data sets and number of cores with modern GPU architectures, which was successfully achieved. The proposed changes also lead to significant reduction in execution time. The execution times were measured on an NVIDIA graphics card, taking into account the possible distributions of the input data.

The enhanced 5G network capabilities for mission-critical communications (MCC) can be utilized by first responders in different use cases, both inland and for maritime safety purposes, including the support for Search and Rescue (SAR) missions. Fast and secure information exchange between control room dispatchers and on-site assets is of core importance for an efficient and timely response. 5G network slicing, enhanced data rates, low latency services, machine-type, and sidelink communications, enable successful management in a crisis environment through coordination of the latest generation of surveillance devices, unmanned vehicles (aerial and surface), various sensors, and actuators, virtual reality services, etc. This paper first provides a brief overview of the most important 5G capabilities and services that improve MCC. Then, experiences collected in two pilots realized in the frame of H2020 project RESPOND-A, concerning 5G support for MCC in earthquake and forest fire scenarios, as well as the planned pilot in maritime SAR operation, are presented.

Predictive modelling and AI have become a ubiquitous part of many modern industries and provide promising opportunities for more accurate analysis, better decision-making, reducing risk and improving profitability. One of the most promising applications for these technologies is in the financial sector as these could be influential for fraud detection, credit risk, creditworthiness and payment analysis. By using machine learning algorithms for analysing larger datasets, financial institutions could identify patterns and anomalies that could indicate fraudulent activity, allowing them to take action in real-time and minimize losses. This paper aims to explore the application of predictive models for assessing customer worthiness, identify the benefits and risks involved with this approach and compare their results in order to provide insights into which model performs best in the given context.

Vulnerability Assessment and Penetration Testing (VAPT) is an important component of an organization's overall security strategy. VAPT helps identify security vulnerabilities in a computer system, network, or web application, allowing organizations to take corrective measures to address these vulnerabilities and prevent potential security breaches. By conducting regular VAPT, organizations can improve their security posture and reduce the likelihood of successful attacks. In this paper Metasploit was used to show importance of regular vulnerability assessment of critical systems in order to discover vulnerabilities before attacker do it and exploit them. The authors showed Metasploit beside its usage to conduct a vulnerability assessment, it can be utilized by attackers to harm systems. VAPT is not a one-time event, but rather a ongoing process. As new vulnerabilities are discovered and new threats emerge, organizations need to regularly assess their systems to ensure they are protected.
漏洞评估和渗透测试(VAPT)是组织整体安全策略的重要组成部分。VAPT帮助识别计算机系统、网络或web应用程序中的安全漏洞,允许组织采取纠正措施来解决这些漏洞并防止潜在的安全破坏。通过定期进行VAPT,组织可以改进其安全状态并降低成功攻击的可能性。本文利用Metasploit说明了定期对关键系统进行漏洞评估的重要性,以便在攻击者攻击和利用漏洞之前发现漏洞。作者展示了Metasploit除了用于进行漏洞评估之外,还可以被攻击者利用来破坏系统。VAPT不是一次性事件,而是一个持续的过程。随着新的漏洞被发现和新的威胁出现,组织需要定期评估他们的系统,以确保他们受到保护。
