The purpose of this article is to contribute to the access to quality education in Mathematics and Philosophy for all children in the country, including those in remote areas of the capital, through an IPTV platform. To do this, we offer an SDN network integrated into an IPTV infrastructure in order to have an agile and automated interactive platform, but capable of video streaming. Interactivity is managed by Verto-FreeSwitch, agility, streaming and automation are the responsibility of SDN. The interactive IPTV server performs a multicast broadcast for learners. With a web browser or an IPTV client, learners can follow courses and interact in real time with teachers via the Verto-FreeSwitch module. The use of SDN allows to benefit from a better configuration of equipment to optimize data storage servers, but when coupled with IPTV they allow democratization of access to Mathematics and Philosophy courses.
本文的目的是通过IPTV平台,为全国所有儿童,包括首都偏远地区的儿童,提供优质的数学和哲学教育。为了做到这一点,我们提供了一个集成到IPTV基础设施中的SDN网络,以便拥有一个灵活和自动化的交互平台,但能够视频流。交互性由Verto-FreeSwitch管理,敏捷性、流化和自动化是SDN的责任。交互式IPTV服务器对学习者进行组播。通过网络浏览器或IPTV客户端,学习者可以跟随课程,并通过Verto-FreeSwitch模块与教师实时互动。使用SDN可以从更好的设备配置中受益,以优化数据存储服务器,但当与IPTV结合使用时,它们可以使数学和哲学课程的访问民主化。

The rapid growth of IoT (Internet of Things) makes life better, but it can be a burden for IoT users to manage heterogeneous IoT devices in a timely and appropriate manner. In this paper, we propose an IoT device configuration translator for IoT-cloud services that enables IoT users who do not have expertise in IoT environments to efficiently configure their IoT devices. The user's high-level configuration based on natural language is delivered to the translator in IoT-cloud platform using NETCONF (Network Configuration Protocol). The translator, which is designed with three components using automata theory and database mapping information, translates the high-level configuration into a low-level configuration applicable to the IoT devices. This allows IoT users to configure their IoT devices without considering which protocols and platforms they work on.
物联网(IoT)的快速发展让生活变得更美好,但对于物联网用户来说,及时、适当地管理异构物联网设备可能是一种负担。在本文中,我们提出了一种物联网设备配置转换器,用于物联网云服务,使不具备物联网环境专业知识的物联网用户能够有效地配置其物联网设备。用户基于自然语言的高级配置通过NETCONF (Network configuration Protocol)协议在物联网云平台上传递给译者。转换器由三个组件组成,使用自动机理论和数据库映射信息,将高级配置转换为适用于物联网设备的低级配置。这使得物联网用户可以配置他们的物联网设备,而无需考虑他们使用的协议和平台。

Question Leakage has become one of the biggest problems in the last 5–6 years in Bangladesh. Instead of taking different pragmatic steps, it has become very difficult for the exam board controller to check the leakage of question papers. This is a quotidian scenario in Bangladesh. We mainly intend to solve this problem in our proposed system. In our proposed system, there will be a IOT based smart box in which all the board questions will be carried. If anyone tries to open the box illegal to leak the questions before the exam, our proposed system will show us the location details of the box and when the culprit will open the smart box, an image will be captured. In our proposed model, the attempt of tampering the smart box can also be identified.
在过去的5-6年中,问题泄露已经成为孟加拉国最大的问题之一。考试委员会的控制者没有采取不同的务实措施,反而很难检查考卷的泄漏情况。这在孟加拉国是司空见惯的情景。我们提出的系统主要是为了解决这个问题。在我们提出的系统中,将有一个基于物联网的智能盒子,其中将携带所有董事会问题。如果有人试图在考试前非法打开盒子泄露问题,我们提出的系统将显示盒子的位置详细信息,当罪犯打开智能盒子时,将捕获图像。在我们提出的模型中,还可以识别篡改智能盒的企图。

E-government has evolved through constant interaction between technological advances and social change. The competence of each department is limited in solving social issues that are becoming more complex, and it is time to solve the problem creatively through openness and communications based on ICT. Since 2010, each country has been implementing the Digital Transformation Policy to improve national competitiveness by applying digital technology to society as a whole. A paradigm shift in public services is required and a new e-government model is proposed as an alternative. By digitizing 100% of government services, vision is about sustainable development across society and strategies are presented for platform, open data, and human resource training. Specifically, improvements are being made to infrastructure, human resources expansion, ecosystems and public services. Considering the today's infrastructure and digital capabilities of Uzbekistan, the country is expected to enter digitalization at the level of current advanced countries like Korea at present around 2030. To achieve this, government must take the lead in innovation and be exemplary. To do this, digital government should be implemented by 2025. It will be possible to optimize governance and administration, to create a transparent nation and a paperless government and to be processed anywhere without visiting the government office. Ultimately, it will be able to realize the goal of providing multi-channel public service to individuals and companies as entry into one of advanced countries and a hub of e-commerce based on digital economy.
电子政务是在技术进步和社会变革的不断互动中发展起来的。在解决日益复杂的社会问题时,各部门的能力是有限的,现在是通过信息通信技术(ICT)的开放和沟通创造性地解决问题的时候了。自2010年以来,各国一直在实施数字化转型政策,通过将数字技术应用于整个社会来提高国家竞争力。需要公共服务的范式转变,并提出了一种新的电子政务模式作为替代方案。通过100%的政府服务数字化,愿景是关于整个社会的可持续发展,并提出了平台、开放数据和人力资源培训的战略。具体来说,正在改善基础设施、扩大人力资源、生态系统和公共服务。考虑到乌兹别克斯坦目前的基础设施和数字化能力,该国有望在2030年左右达到韩国等当今发达国家的数字化水平。要做到这一点,政府必须带头创新,以身作则。为此,应在2025年之前实施数字政府。这样,就可以优化治理和行政,建立透明的国家和无纸化的政府,在任何地方都可以处理,而不需要去政府办公室。最终,韩国将成为以数字经济为基础的电子商务中心和先进国家之一,实现向个人和企业提供多渠道公共服务的目标。

In order to maximize the capacity of the cooperative communication system, a power allocation scheme for multi-relay AF cooperative system based on blind relays is presented in this paper. Under the premise that the source power is known, the power allocation problem is modeled to maximize the capacity of the system and transformed into the standard convex optimization. The power allocation factors of each relay is obtained by solving the Karush-Kuhn-Tucher (KKT) condition. Finally, the capacity and outage probability of the proposed scheme are provided for the proposed power allocation scheme. Compared with the typical equal power allocation, the proposed convex optimization-based power allocation scheme achieves better performance.
为了使协作通信系统的容量最大化,提出了一种基于盲中继的多中继自动对焦协作系统的功率分配方案。在源功率已知的前提下,以系统容量最大化为目标对功率分配问题进行建模,并将其转化为标准的凸优化问题。通过求解Karush-Kuhn-Tucher (KKT)条件,得到各继电器的功率分配系数。最后给出了所提出的功率分配方案的容量和停电概率。与典型的等功率分配方案相比,所提出的基于凸优化的功率分配方案具有更好的性能。

Today, quite a lot of attention is paid to the integration of information technology and medicine. E-health network development makes it possible. The principles of e-health networks imply the use of small-sized mobile medical devices - sensors and actuators. As a rule, sensors, and actuators are combined into a network and operate with other network devices: gateways, cloud servers, etc. The article discusses the network scheme, including a portable near-infrared spectrometer for molecular analysis of food products and its interaction with the Internet in the process of data collection and processing.

DNA Microarray technology is a valuable advancement in medical field but it gives birth to many challenges like curse of dimensionality, storage and computational requirements. In this paper we have proposed, a multiple filters and GA wrapper based hybrid approach (MF-GARF) that incorporates Random forest as fitness evaluator of features. The proposed hybrid approach MF-GARF is comprised of three phases relevancy block; containing information theory based filters Information Gain, Gain Ratio and Gini Index, responsible for ensuring relevancy and removal of irrelevant and noisy features. Second phase is Redundancy block; incorporating Pearson Correlation statistics to remove redundancy among features, and then final phase Optimization Block; containing Genetic Algorithm wrapper with Random Forest as fitness evaluator, responsible for generating an optimal feature subset with high predictive power. Random Forest with 10-fold cross validation is used to calculate the classification accuracy of selected feature subset. Experiments are carried out on 7 publically available benchmark Microarray cancer datasets and the proposed algorithm has achieved good accuracy with minimal selected features for all datasets. The comparison with other state of the art hybrid techniques validates the effectiveness of our proposed approach.
DNA微阵列技术是医学领域的一项有价值的进步,但它也带来了许多挑战,如维度诅咒、存储和计算要求。在本文中,我们提出了一种基于多滤波器和GA包装器的混合方法(MF-GARF),该方法将随机森林作为特征的适应度评估器。提出的混合方法MF-GARF由三个阶段的关联块组成;包含基于信息论的滤波器信息增益,增益比和基尼指数,负责确保相关性和去除不相关和有噪声的特征。第二阶段为冗余块;结合Pearson相关统计去除特征之间的冗余,最后进行优化块;包含以随机森林作为适应度评估器的遗传算法包装器,负责生成具有高预测能力的最优特征子集。使用10倍交叉验证的随机森林计算所选特征子集的分类精度。在7个公开的微阵列癌症基准数据集上进行了实验,结果表明,该算法在所有数据集上都以最小的选择特征达到了较好的准确率。与其他最先进的混合技术的比较验证了我们提出的方法的有效性。

This paper proposes an wireless disconnected transfer method which realizes the continuous data transfer of wireless digital patches in wireless bioinformation sensing networks. It describes a bioinformation sensing system and a bioinformation sensing method using mobile patches. It is a research on wireless sensing system and wireless gathering method based on information gathering interface using mobile patch. The unguided wireless channel generally shows link disconnections and propagation delays due to their low signal connectivity. Conventional wireless sensing network protocols did not consider any fault models about physical wireless link faults. Consequently, they have shown data transfer inefficiency for both data link control and physical wireless link control. To overcome these wireless digital patch environmental problems, this paper suggests a new wireless smart agent system, which provides wireless or mobile patches with previous transfer layer protocols compensated.

In this paper, an orthogonal polynomial based complex Gaussian process of nonlinear power amplifier for the filter bank multicarrier modulation (FBMC) systems is proposed. One of the most challenging problems for the FBMC systems is a non-linear distortion caused by a high power amplifier (HPA). Due to the signals for the FBMC communication scenario are modeled as a complex-Gaussian distribution, an analytical expression of the HPA characteristic based on an orthogonal polynomial method by using an upper triangle solution for complex-Gaussian process is derived in this paper. To ensure the robustness of the proposed orthogonal polynomials, the different input distribution such as an exponential and Rayleigh distribution is investigated. In the simulation, a normalized mean squared error (NMSE) and the probability of error performances (BER) in the additive white Gaussian noise (AWGN) channel and the frequency-selective Rayleigh fading channel of the proposed orthogonal polynomial method is determined. Simulation results show that the proposed orthogonal polynomial method significantly outperforms the conventional polynomial method. Furthermore, the proposed orthogonal polynomial based complex-Gaussian input distribution is superior to the exponential, and Rayleigh input distribution in terms of both NMSE and BER performance.
针对滤波器组多载波调制(FBMC)系统,提出了一种基于正交多项式的非线性功率放大器复高斯过程。高功率放大器(HPA)引起的非线性失真是FBMC系统最具挑战性的问题之一。由于FBMC通信场景的信号建模为复高斯分布,本文利用复高斯过程的上三角解,导出了基于正交多项式方法的HPA特性解析表达式。为了保证所提出的正交多项式的鲁棒性,研究了不同的输入分布,如指数分布和瑞利分布。在仿真中,确定了正交多项式方法在加性高斯白噪声信道和频率选择瑞利衰落信道下的归一化均方误差(NMSE)和误码率(BER)。仿真结果表明,所提出的正交多项式方法明显优于传统的多项式方法。此外,本文提出的基于正交多项式的复高斯输入分布在NMSE和BER性能方面都优于指数和瑞利输入分布。
