One of the problems with Smart Transportation is the problem of cost and travel time. This problem is known as the Variable Routing Problem (VRP). In some real cases, in addition to considering route selection, there are limitations on the capacity and time period for the vehicle to serve each customer known as Time Windows, so VRP has developed into Variable Routing Problem with Time Windows (VRPTW). One way to solve VRPTW is to use metaheuristic methods. However, the metaheuristic method has a weakness, which are it can get stuck in local optimums and fail to find better global solutions. To overcome this, a combination with other methods or known as hybrid is needed. The formulation of this research problem is how to develop a Smart transportation model using a metaheuristic hybrid algorithm. The purpose of this study is to develop a Smart transportation model using a metaheuristic hybrid algorithm. The method used is to combine two metaheuristic algorithms, which are the Dragonfly Algorithm (DA) and the Variable Neighborhood Search (VNS). The result of this research is a new algorithm model which is a hybrid between DA and VNS. Through a combination of global exploration using DA and local exploitation using VNS, this algorithm is expected to be able to find a better solution and faster convergence in solving VRPTW problems © 2024 IEEE.

The design of a 180° output phase difference Wilkinson power divider for L-band applications is detailed in this article. The Wilkinson power is generated through the utilization of the parallel coupler's phase shifter. To showcase the potential of the suggested power divider, an FR4 microwave substrate is fabricated with a narrow band of 1.6 GHz to accommodate radio astronomy systems. The insertion loss, return loss, and isolation loss for the power divider's difference phase are accurately simulated at the operational frequency. © 2024 IEEE.

Bowel preparation is considered a critical step in colonoscopy. Manual bowel preparation assessment is time consuming and prone to human errors and biases. Automatic Bowel evaluation using machine/deep learning is a better and efficient alternative. Most of the relevant literature have focused on achieving high validation accuracy, where private handy-picked dataset does not reflect real-environment situation. Furthermore, treating a video dataset as a collection of individual frames may produce overestimated results. This is due to the fact a video contains nearly identical consecutive frames, hence, dividing them into training and validation sets yields two similar distributed datasets. Given a public dataset, Nerthus, we show empirically a significant drop in performance when a video dataset is treated as a collection of videos (depicting the real environment/context), instead of a collection of individual frames. We propose a model that utilizes both sequence and none-sequence (spatial) information within videos. The proposed model achieved on average 83% validation accuracy across 4 validation sets, whereas, the state-of-the-art models achieved on average a range of 66%–72% validation accuracy. © 2023, Springer Nature Switzerland AG.

This paper presents a microstrip antenna with dual-band operating frequencies by etching multiple slots on the radiating patch of the antenna. In wireless communication systems, microstrip antenna operating at multiple frequencies are in demand and has a significant influence for ISM (Industrial Scientific Medical) applications. The proposed antenna is specifically designed to operate at both 2.4 and 5.8 GHz ISM frequency band. The dual-band antenna was designed and simulated using CST-MWS software with a patch dimension of $39.4\ \text{mm}\times 39.5\ \text{mm}\times 1.575\ \text{mm}$ , and mounted on a RT/duroid 5880 substrate with a dielectric constant $\varepsilon_{r}=2.2$ , loss tangent of $\delta=0.0009$ and thickness of 1.575 mm. Based on the results, the antenna exhibit an $S_{11}$ of −29.23 dB and VSWR of 1.07 at 2.4 GHz, and $S_{11}$ of −18.55 dB and VSWR of 1.26 at 5.8 GHz. The good consistency between $S_{11}$ predicted and measured results confirm the antenna's ability to be implemented for ISM band applications such as Wi-Fi, WLAN and wireless sensor network.

In this Internet era, we have become heavily dependent on the World Wide Web and it has become a basic amenity for humans. A normal user can be trapped easily in this vicious web if not careful enough. It is a field that requires users to be on their toes every time they try to connect to this enormous interconnection of networks. Reports and Surveys have said that in the coming years, Cybercrime could become the biggest threat. In this proposed work, the authors have deployed applications and designed malware for the purpose of simulating various kinds of cyber-attacks so that they could study their effects & affects and ultimately devise solutions to resolve the vulnerabilities in a system. These applications included networking concepts & protocols and a software based keylogger which was developed with no malicious intent, but to analyse the architectural view or design of a malware and to study the stages of a malware attack like entry, distribution, exploitation, infection and execution. Efforts have been made to demonstrate spooting attacks with an idea of identifying vulnerabilities and security loopholes in a particular system that can be exploited by an attacker if not resolved within time. © 2023 IEEE.

This work offers a low profile, and enhanced microstrip patch antenna for 5G and Wi-Max applications. The proposed design is based on a patch antenna embedded with reflective surface metamaterial consisting of an array of 5 × 5 elements. The simulated and measured of S11 has been observed to determine its performance. The advancement of Frequency Selective Surface (FSS) evolution known as Reflective Surface (RS) metamaterial has been adopted to integrate with the patch antenna. This design has a small size of 107 mm × 107 mm. Furthermore, it has been integrated with the microstrip patch antenna under two different configurations which provides a variation performance antenna in terms of reflection coefficient for both configuration 1 and configuration 2, at the operating frequency of 3.5 GHz. For configuration 1, no significant changes have been observed. While in configuration 2, the resonant frequency of the patch antenna has been shifted up and down with the best S11 is -40dB at 3.4 GHz

This paper aims to present a flexible and wideband microstrip antenna on a Thermoplastic Polyurethane (TPU) substrate. TPU is used as the substrate in designing the flexible antenna due to its high flexibility, elasticity, and strength properties. The characteristic of the antenna is further enhanced by inserting inset slot feed and using a partial ground plane to improve the resonant frequency and realize a wide bandwidth, respectively. The performance of the proposed antenna is analyzed and compared with a common antenna design method which typically produces a narrower bandwidth. The antenna shows promising results resonating from 7.5 to 10.2 GHz with a percentage increase of 17.4% in terms of bandwidth, and greater return loss along the operating frequency range.
