This paper presents a flexible dual-band antenna for wearable applications. The proposed antenna consists of radiating patch, microstrip feedline, and ground plane. The four corners of the radiating rectangular patch are etched and circular slot is cut inside the patch to resonate in the Industrial Scientific Medical (ISM) band at 2.45 GHz and 5.8 GHz. The proposed antenna is designed on flexible material. The substrate material is cotton jean with dielectric constant of 1.7, loss tangent of 0.02, and the thickness of 1 mm. The overall size of antenna is $82times 74mathrm{mm}^{2}$. The radiation pattern of proposed antenna is unidirectional at both frequencies. The proposed antenna has the gain of 4.09 dBi and 3.19 dBi at 2.45 GHz and 5.8 GHz, respectively. The specific absorption rate (SAR) value which effects on human body is less than 2 W/kg according to IEEE95.3 standard. The SAR values of proposed antenna are 0. 3SSW/kg and 0. 35SW/kg at 2.45 GHz and 5. S GHz, respectively, over 1 gram of mass tissue. The simulated results confirm that the proposed antenna can be used for wearable applications.

A compact and simple schematic of Nd: YAG laser is highly required in various industrial applications. In order to achieve smaller schematic of Nd: YAG optical resonator than that from the previous work, this paper presents the analysis of the effects of Nd:YAG medium length and optical cavity length to Nd:YAG laser characteristics by using LASCAD software. It is found that the laser output power and temperature distribution inside Nd:YAG medium are not significantly affected by Nd:YAG medium length. And the optical cavity length affects to the spot sizes of laser beam at both laser mirrors, and that also affects to laser stability. However, the laser output powers are nearly the same by varying the optical cavity length. Based on there results, finally, the length reduction of compact high power Nd: YAG laser can be achieved by decreasing Nd:YAG medium length from 60 mm to 15 mm, and optical cavity length from 260 mm to 115 mm, respectively. By using this proposed structure, the output laser characteristics are almost the same with those of standard Nd:YAG laser structure.

Sparse Code Multiple Access (SCMA) is a multiple access that has the potential to address the needs of future networks. However, the commonly researched SCMA has a traditional design known as regular SCMA, may have drawbacks in serving massive connection networks and supporting various user services. It has been hypothesized that Doubly-irregular SCMA (DI-SCMA) ameliorates the shortcomings of regular SCMA. In this study, we present codebook designs oriented to Spatial Modulation (SM-oriented) and Quadrature Spatial Modulation (QSM-oriented) with Multiuser Detection (MUD) Q=3 to enhance the spectrum efficiency of downlink DI-SCMA with an overloading factor of 225%. The SM-oriented and QSM-oriented codebook design permits downlink DI-SCMA to transmit more bits from multiple users concurrently. The simulation is performed in a Rayleigh fading channel, demonstrating that our proposed codebook designs are suitable for downlink DI-SCMA.

A strongly stabilization is the control method to make control systems stable using stable controllers. Using this method, it is possible to construct a highly reliable control system because it has robustness. The controller needs a pole at the origin to follow the step reference input without steady-state error. A semi-strongly stabilizing controller is proposed that has a pole at the origin and the others in the open left half plane. In some cases, the controller needs to have poles on the imaginary axis; for example, the control systems follow sinusoidal signals and the self-repairing control systems with faulty sensors using resonance. Therefore, Kimura proposed extended semi-strongly stabilizing controllers with poles on the imaginary axis and other poles in the open left-half plane. Niiyama propose control system with failure detection by adapting the extended semi-strongly stabilizing controller to the self-repairing control system with failure sensor using resonance. However, this method remains an error between the output and the reference input. To eliminate this error the controller needs a pole at the origin and two pairs of poles on the imaginary axis. In this paper, to overcome this problem, we propose an extended semi-strongly stabilizing controller with a pole at the origin and two pairs of poles on the imaginary axis. In addition, we clarify the parameterization of all extended semi-strongly stabilizable plants and of all extended semi-strongly stabilizing controllers for extended semi-strongly stabilizable plants.

This research proposes passive techniques for magnetic field mitigation in the 69/115 kV underground power system installed by the Metropolitan Electricity Authority (MEA). The passive techniques which are: conductive loop, conductive shield, and ferromagnetic shield were designed and simulated by using the Finite Element Method Magnetics (FEMM) program. A comparison of the magnetic field with and without a mitigation system is obtained. Finally, the simulation results show that all passive techniques can reduce the magnetic field values to be lower than the reference value given by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and European standards.

Severa1 intelligent control systems these days are utilized by the concept of automatically tuning, especially in proportional-integral-derivative (PID) controller. Furthermore, increasing sensors and actuators disrupt the conventional computing system, which has limited resources and is difficult to meet the timing requirement. This paper develops a hardware implementation of PID auto-tuning based on the particle swarm optimization (PSO) with the parallel architecture of particles and variables so that latency is heuristically minimal. The result shows that the proposed hardware performs 1000x and 800x compared to conventional microprocessors. From the evaluation process, performance and resource utilization are found to be satisfactory compared to conventional PID.

The need for ultimate security in the enterprise network is significantly crucial in today’s network. Likewise, redundancy, availability, and reliability are the primary main key to an internet connection. Mostly, network administrators use multiple routers and firewalls in their networks. In essence, asymmetric traffic imposes a serious issue with those designs and in some occasions the network traffic might be disturbed. In order to address the asymmetric connection to the firewall, this work proposes by use of another segment network for multi-routers and a firewall called a fusion network. In addition, this paper takes advantage of the existing enhanced technology such as MP-BGP MPLS VPN. Moreover, applying to the real world is also considered. Finally, the comparison with other network designs and the performance of our design are discussed.

The study presented a novel chipless RFID sensor designed for the detection of cracks in non-metallic materials. The sensor utilized square coplanar split-ring resonators (SRR) and was mounted on the material under test (MUT), including materials such as Teflon (PTFE), Polycarbonate, and Kapton (Polyimide), for detecting cracks. To assess the effectiveness of the sensor in detecting cracks, simulation experiments were conducted using the CST Microwave Studio software, which analyzed shifts in the resonant frequency. The resulting RCS spectra demonstrated a clear correlation between the size of the crack and the resonance frequencies of the chipless RFID sensor, confirming the sensor’s ability to detect cracks in nonmetallic materials.
