The comparative study of model-based and appearance Based gait recognition for leave bag behind

Nowadays, the increasing number of crimes and violence in the world has become a concern of modem society. This is why the need for criminal recognition using gait used for civilian and forensic analysis applications has evoked considerable interest. The literature accurate the result can be found in gait recognition by leave bag behind detection especially in .the critical area examples airport and shopping mall environment. This is important because the method used capable of identifying the subject based on their gait and can be presented as the most probable subject as a strong evidence for criminal identification. This research limited to leave the bag behind detection on gait recognition. In this research, the analysis perfonned using two methods which are Model-Based approaches and Appearance-Based approaches. The selected methods were implemented in MATLAB R2014a and R Studio and tested with a standard dataset from the Chinese Academy of Science (CASIA) and tested using two classifiers which is Support Vector Machine (SVM) and KNN (K nearest Neighbour) based on accuracy and misclassification rates (MER) metrics. The experiment results show that the accuracy and misclassification rate (MER) of Appearance-based approaches obtained is 93.66% and 6.33% respectively tested on SVM classifier then the accuracy and misclassification rate (MER) of Appearance­based approaches is 97.66% and 2.33% respectively tested on KNN algorithm. Meanwhile, the accuracy and misclassification rate (MER) of Model-based approaches obtained is 97.00% and 3.00% respectively tested on SVM classifier then the accuracy and misclassification rate (MER) of Model-based approaches is 99.00% and 1.00% respectively tested on KNN algorithm. It can be concluded from experiments conducted by Model-based approaches better than Appearance-based approaches because Model-Based approaches higher precision value as well as low misclassification

Development of an IoT-Based PLC Trainer: Bridging the Practical Divide in Industrial Automation Education

In the dynamic landscape of digitalization, the fusion of Internet of Things (IoT) tech-nology with Programmable Logic Controllers (PLCs) has emerged as a pivotal avenue, promising enriched practical experiences and heightened comprehension. This paper navi-gates through recent studies elucidating the applications of IoT-based PLCs in diverse con-texts, from smart home automation to traffic control and resource management. Notable contributions include remote monitoring systems, smart traffic control, water level moni-toring, and automated greenhouses. Acknowledging persistent challenges in understanding and implementing PLCs, this research introduces an innovative IoT-based PLC Trainer Kit. The kit aims to elevate prac-tical learning by providing hands-on experiences, refining skills, and optimizing applica-tions across various domains. Emphasizing the pivotal role of practical training in PLC education, the study conducts a needs analysis, followed by the design, development, and testing phases of the IoT-based PLC Trainer. The prototype, employing an Omron CPM1A PLC, pneumatic components, sensors, and an intuitive interface, undergoes meticulous testing, affirming its readiness for deployment. The development of the IoT-based PLC Trainer marks a significant achievement, ad-dressing the gap between theoretical knowledge and practical application. Through metic-ulous design, material selection, and testing, the trainer demonstrates optimal functionali-ty and user-friendliness. Anticipating its deployment in educational institutions and in-dustrial setups, the trainer is poised to contribute to the realm of industrial automation, offering a practical understanding of PLC applications within the Internet of Things con-text. This project not only signifies technical expertise but also bridges the gap between theory and practice in the dynamic domain of IoT-driven programmable logic control-ler

Characterization and treatment of titanium dioxide, TiO2 via ultrasonic process with melastoma malabathricum as sustainable sensitizer for photovoltaic slar cell

Dye-sensitized solar cells (DSSCs) have been fabricated with doped Titanium Dioxide, TiO2 which are based on natural dyes from Malaysia tropical fruits, wherein contain interlocking groups; the carbonyl and hydroxyl groups of the anthocyanin molecule which enhance the photosensitization effect due to the high interaction on the surface of the film. Such a natural dye extracted from Melastoma Malabathricum can be subjected to molecular tailoring to give a superior dye preparation, offering a wide range of spectral absorption; covering the entire visible region (400 – 700 nm). This study is based on a series of TiO2 preparations designated U1 and U2 (without and with additive respectively), and those treated with ultrasonic energy, namely U3 and U4 (without and with additive respectively). 10 minutes of sonication of the metal oxide led to its breakdown from agglomeration at the micro to the nano scale. Furthermore the additive (4-tert-butylpyridine) in potassium iodide, KI3 electrolyte, effects the rate of electron injection into the oxidized dye sensitizer. Sonication of TiO2 reduced the particle size agglomerates from 0.37 µm down to 0.15 µm; this treatment led to a more consistency with high porosity, enabling enhance absorption and anchorage of the dye sensitizer. Sonicated sample U4, with addition of electrolyte additive gives, open circuit voltage, Voc= 0.742 V, short circuit current, Isc= 0.36 mA, fill factor, FF= 57.012 and 0.039 % of cell’s efficiency. Evidently, sonication and addition of additive for KI3 electrolyte offer enhanced capability for further application

Future RAN architecture: SD-RAN through a general-purpose processing platform

In this article, we identify and study the potential of an integrated deployment solution for energy-efficient cellular networks combining the strengths of two very active current research themes: 1) software-defined radio access networks (SD-RANs) and 2) decoupled signaling and data transmissions, or beyond cellular green generation (BCG2) architecture, for enhanced energy efficiency. While SD-RAN envisions a decoupled centralized control plane and data-forwarding plane for flexible control, the BCG2 architecture calls for decoupling coverage from the capacity and coverage provided through an always-on low-power signaling node for a larger geographical area; the capacity is catered by various on-demand data nodes for maximum energy efficiency. In this article, we show that a combined approach that brings both specifications together can not only achieve greater benefits but also facilitate faster realization of both technologies. We propose the idea and design of a signaling controller that acts as a signaling node to provide always-on coverage, consuming low power, and at the same time host the control plane functions for the SDRAN through a general-purpose processing platform. The phantom cell concept is also a similar idea where a normal macrocell provides interference control to densely deployed small cells, although our initial results show that the integrated architecture has a much greater potential for energy savings than phantom cells

Enabling virtual radio functions on software defined radio for future wireless networks

Today's wired networks have become highly flexible, thanks to the fact that an increasing number of functionalities are realized by software rather than dedicated hardware. This trend is still in its early stages for wireless networks, but it has the potential to improve the network's flexibility and resource utilization regarding both the abundant computational resources and the scarce radio spectrum resources. In this work we provide an overview of the enabling technologies for network reconfiguration, such as Network Function Virtualization, Software Defined Networking, and Software Defined Radio. We review frequently used terminology such as softwarization, virtualization, and orchestration, and how these concepts apply to wireless networks. We introduce the concept of Virtual Radio Function, and illustrate how softwarized/virtualized radio functions can be placed and initialized at runtime, allowing radio access technologies and spectrum allocation schemes to be formed dynamically. Finally we focus on embedded Software-Defined Radio as an end device, and illustrate how to realize the placement, initialization and configuration of virtual radio functions on such kind of devices
