Game-Based Learning (GBL) is considered as an effective tool to motivate and engage students to learn. The literature indicates that Game-based learning using video games has allowed game developers to apply Bloom's Taxonomy of learning. Although there are several video games available on the Internet as examples of GBL, very little seem to present the use of avatar customization as a key feature. Avatar or character customization is a ubiquitous feature found on video games which allow users to create their own experiences over the game. Literature indicates that autonomy, a product of character customization, leads to game enjoyment and game loyalty. When users experience enjoyment in the game, they are likely to achieve better. This paper adds novelty to the body of knowledge in game-based learning by designing a mobile game application dubbed as “ALGEbright” that incorporates the use of avatar customization for the Algebra subject in secondary education. The ALGEBright is designed to provide an easy to understand and friendly user interface intended for beginners. Users can access the mobile app anytime and anywhere at their own convenience, a key feature of Mobile Learning. What makes the mobile app unique is aside from the character customization, the teacher or instructor module is incorporated in the application. This module allows teachers to view the results of the students and manage the exercises in the form of games. Software development methodology, features, and implications are further discussed in the paper.

Salient rotor field excitation flux switching synchronous motor (FEFSSM) could be considered as the most feasible candidate in high speed condition owing to their robustness and flux control ability. Nevertheless, the existing FEFSSM utilizes overlapped field excitation coil (FEC) and armature windings, the material cost, motor size and rise of copper loss should be overcome. Besides, deterioration in power and torque densities due to salient structure of rotor weight needs to be improved. In this research, the salient rotor and overlapped windings in conventional FEFSSM are replaced with segmented rotor and non-overlap winding configuration, respectively. Initially, design structures of four FEFSSM topologies i.e., 12S-3P, 12S-6P, 12S-9P and 12S-15P are conducted using 2D finite element analysis (FEA). Then, performances in term of flux linkage, induced voltage, flux enhancement, flux lines and distributions, allowable cogging torque, average torque and maximum power are analyzed. Preliminary results show that the proposed FEFSSM has produced shorter flux path and less copper usage, mainly from the effect of segmental rotor and non-overlap winding. Finally, 12S-6P stator rotor configurations has been selected as the best contenders which deliver the highest flux linkages, peak torque and maximum power of 4.12 mWb, 0.77 Nm and 260 W, respectively
凸转子磁场励磁开关同步电机(FEFSSM)具有鲁棒性和磁链控制能力，是高速条件下最可行的选择。然而，现有的FEFSSM采用重叠励磁线圈(FEC)和电枢绕组，材料成本，电机尺寸和铜损耗的增加应该克服。此外，由于转子重量凸起结构导致功率和转矩密度下降的问题也需要改进。在本研究中，将传统FEFSSM中的凸极转子和重叠绕组分别替换为分段转子和无重叠绕组结构。首先，利用二维有限元分析(FEA)对12S-3P、12S-6P、12S-9P和12S-15P四种FEFSSM拓扑结构进行了设计。然后分析了磁链、感应电压、磁链增强、磁链线及分布、允许齿槽转矩、平均转矩和最大功率等方面的性能。初步结果表明，采用分段转子和无重叠绕组的效果显著，缩短了磁通路径，减少了铜的使用量。最终，12S-6P定子转子配置成为最佳竞争对手，其磁链最高，峰值转矩为4.12 mWb，最大功率为0.77 Nm，最大功率为260 W

Kidnapping and harassment is not only a global issue but also a historic issue in Bangladesh. In between the years of 2010 and 2018, the total number of kidnapping events were found, 6708 (Avg. 745.33 events per year) in Bangladesh. The government is trying to capture and punish the kidnappers. But there are a few ways by which the victim can also notify the responsible persons about the unwanted incidents in real-time. This research proposes to design and develop an anti-kidnapping and anti-harassment mobile application that is consists of two modules, the Avoidance and the Detection modules. The Avoidance module notifies the user about some unsafe locations. The Detection module is further divided into four submodules, the Notification module, Sound module, Sensor module, and Spy module. The Notification module is activated by pressing the SOS key and the Sound module is activated by voice command. Both of these modules can send the current location of the user by sending SMS to some selected contact numbers. In the Voice module, the audio voice can be recorded for 15 seconds and saved in phone storage or cloud. The Sensor module uses accelerometer sensor and compass sensor. During unwanted circumstances, the accelerometer sensor is activated by shaking the phone three times and the compass sensor is activated by the movement of the user. The Notification module is tested by sending notifications in different areas in Bangladesh. It is found that the average response time of the notification module is 0.74 milliseconds. The complete application is tested by following the System Usability Scale (SUS) method. It is found that the SUS score of the system is 75.56 %, which indicates that the system is good enough to use.

Absorber material is a good alternative for stealth application. It has a feature to prevent microwave reflections. A microwave metamaterial absorber base on cross-shaped is proposed on this work. The target of this work is to find optimal parameter cross-shaped unit cell design for high absorbance performance at microwave spectrum. The cross-shaped design was chosen due to its simple design and generating insensitive polarization. The peak of absorbance performance for 15 mm of width, 20 mm of width, 25 mm of width and 30 mm of width are 0.96 at 4.3 GHz, 0.86 at 3.9 GHz, 0.74 at 3.8 GHz, and 0.7 at 3.7 GHz, respectively. The highest peak of absorbance performance is cross-shaped with 15 mm of width. The microwave metamaterial absorber base on cross-shaped yields insensitive polarization performance. There is a perfect matching of absorbance performance with a difference of polarization angle. The microwave metamaterial absorber base on cross-shaped presents high absorbance performance for several incident angles case. At 4-4.7 GHz region, there is existed high absorbance performance for 20° - 80° incident angles (θ). Three absorbance peaks are existed for θ =20° at 4-4.7 GHz region. The θ= 40°, θ= 60°, and θ= 80° yield another absorbance peak at 3.4 – 3.8 GHz region. In this region, the high absorbance was yield only for θ= 80° case. Overall, the microwave metamaterial absorber base on cross-shaped is a good alternative for stealth application due to relative high absorbance performance and insensitive polarization.

Industry 4.0 is the fourth and current working paradigm leaning on data exchange, data analysis and Internet of things for complete automation and optimization of manufacturing technologies. This I4.0 paradigm enables the possibility for optimal autonomous decision making and full autonomous operation of the facility. Since all manufacturing processes are inherently in-deterministic, optimal decision making will only work when provided with realistic uncertainty models. The authors have observed that the typical used prediction models are not accurate as they do not represent the in-deterministic nature of the processes in a realistic manner. The objective of this paper is to use the IoT- based logged data to design more relevant uncertainty models to optimize the industry 4.0 framework. For this purpose, p-box models are used to represent production variation as function of unknown in-deterministic parameters. Furthermore, by using regression learning on the database, we show that the uncertainty can be decreased. It is shown that classic stochastic models are not able to capture the full in-deterministic nature of the uncertainties. It makes therefore sense that autonomous decision making based on such stochastic models are unreliable and sub-optimal. Future research possibilities are discussed, based on the proposed uncertainty models, together with possible notions that will help in the development of reliable optimal decision making and more accurate adaptable Industry 4.0 framework.

Multi-modal robots exhibit poor performance in locomotion modes due to its additional weight when compared to a single modal robot. Furthermore, the kinematics of a multimodal robot is more complex due to the increased number of actuators hence more prone to errors and malfunctions. The aim of this study was to use topology optimization to reduce the weight of components in a multi-modal robot, optimizing its ability to withstand stresses and loads. An algorithm for the robot's locomotion mode had been implemented using 8-bit microcontrollers. The prototype of this robot had been tested on different types of mock-up terrains. The topology of components of prototype was optimized and 3D printing was used to fabricate them due to their complex and irregular shapes. Utilization of topology optimization reduced the weight of component up to 54.40% while retaining the capability of the component to withstand the stresses and loads, proving the potential of this technique in robot development. The walking algorithm was implemented with trigonometry instead of inverse kinematics due to the limit of 8-bit microcontrollers. Complementary and exponential filters were implemented to improve the performance of flying locomotion, thus featuring auto-levelling in aerial mode. The robot was able to harness the advantage in both flying and walking over speed and energy efficiency after testing in mock-up terrains, making the robot more versatile in many situations.

Today's power system grids are massively interconnected with newer technologies and control devices integrated into the system all for enhanced efficiency and economic benefits in operation. This property makes the grid highly dynamic and diverse thus, concluding it as the biggest artificial living network on earth. To observe the power system security requirements, planning and safe operation of today's system becomes imperatively necessary. If the power system security criterion is ignored, then power blackouts will be born and the system response will distribute severe socio-economic impact, therefore, it is essential to know the dynamic security assessment (DSA) for the systems and allow it to remain in a stable state. This paper will execute a comparison of each method of transient stability index (TSI) and transient stability assessment (TSA) and how the classes of these methods are implemented. The classifications will highlight the difference between the methods and show the individual benefits and setbacks when applied on a practical large sized power system. This review paper can deliver an in-depth knowledge into the development of a rapid and reliable rotor angle transient instabilities technique towards improving DSA of a practical large-sized power system.

Process of controlling pressure in process industries becomes difficult when the conventional controller is used because of not capable of handling delay time, rise time and steady-state error. So, in this work, the method of the combining the conventional controller with the optimised hybrid system is considered. In this hybrid system the combination of fuzzy logic controller and PID controller is taken for evaluation and performance analysis over the pressure process. Generally fuzzy controllers use a rule base to describe relationships between the variables that are used in the processes. The performance analysis is done for different conventional controllers like PID and fuzzy PID. The performance analysis for the controllers is based in considering conventional resultant parameters like rise time, peak overshoot and settling time. We proposed a hybrid fuzzy PID controller which utilises the properties and advantage of the fuzzy and PID controllers. The effectiveness of the Hybrid fuzzy PID controller designed is demonstrated in pressure process.

In this paper, a multi-input power converter (MIPC) dedicated for renewable energy system (RES) using an active current sharing scheme is proposed. The designed power converter consists of three inputs from RES which are photovoltaic and fuel cells. It is known that the RES has a varying and intermittent characteristic in its output. Hence, the control scheme is required to stabilize the regulated output. This paper mainly focuses on designing an MIPC which employs an averaged current sharing mode as its active current sharing error signalling processing control strategy. A conventional control for the same MIPC converter using pulse width generator were also simulated for comparison purposes. The MIPC with three varying input voltage was design to produce 400 V DC. The simulation of both MIPC under different input voltage condition was carried out. The results show that the proposed scheme was able to regulate and provide the desired output voltage to a certain input voltage variation as opposed to the fixed control.

Reinforcement Learning (RL) algorithm with deep learning techniques helps to solve many complex problems of today's world, such as to play a video game and autonomous navigation in the robots using the raw image as an input. Deep learning provides the mechanism to RL which enables the agent to solve the human level task. The rise of RL begins when a computer player beat the human expert in the most difficult game Go [6]. In this paper, we discuss some important topics such as the general view of reinforcement learning, methods, and algorithms of reinforcement learning and challenges which reinforcement learning is facing. Finally, we discussed a survey of implemented algorithms of RL in the field of robotics for autonomous visual navigation.
