In this paper, we have analyzed the analog single event transient (ASET) performance of MOSFET based LNA circuits at two different frequencies (one in X band and another in Ka-band) to study the frequency dependency. The ASET impact is analyzed in the time and frequency domains under two scenarios, (i) absence of the RF input signal and (ii) the Presence of the RF input signal. In the first case, the collected charge (Qc) is taken as metric in the time domain and the second case, the spectrogram is used to analyze the disturbing presence in the fundamental frequency due to radiation strike. Based on the QC, the LNA used in X-band is more vulnerable compared to LNA used in Ka-band. The spectrogram results show that the LNA output spectrum in the X-band is disturbed more and stronger to the radiation strike compared to the LNA used in Ka-band.

It is reported that since 2016 there are over sixty thousand diagnosed cases of Leukemia in the United States of America alone. It also suggests that Leukemia is the most common type of cancer seen in the age of twenty. Although the study is based on a Western country, it is equally alarming for an Asian country like Bangladesh where healthcare system is not up to the standard. Researches show that the Chronic Lymphocytic Leukemia has about 83% five-year long survival rates. This paper focuses on Acute Lymphocytic Leukemia (ALL) as this is the most common type of Leukemia in Bangladesh. It is common knowledge among oncologists, that cancer is much easier to treat if it is detected in the early stages. Thus the treatment needs to begin as early as possible. We propose a hands-on approach in detecting the irregular blood components (e.g., Neutrophils, Eosinophils, Basophils, Lymphocytes and Monocytes) that are typically found in a cancer patient. In this work, we first identify 14 attributes to prepare the dataset and determine 4 major attributes that play a significant role in determining a Leukemia patient. We have also collected 256 primary data from Leukemia patient. The data is then processed using microscope to obtain images and fetch into Faster-RCNN machine learning algorithm to predict the odds of cancer cells forming. Here we have applied two loss functions to both the RPN (Region Convolutional Neural Network) model and the classifier model to detect the similar blood object. After identifying the object, we have calculated the corresponding object and based on the count of the corresponding object we finally detect Leukemia. The mean average precision observed are 0.10, 0.16 and 0, where the epochs are 40, 60 and 120, respectively.

Fire incidents often result to associated deaths, injuries, and losses occurring structures and properties, particularly in homes every year. In this study, the researchers proposed a 4-wheeled fire extinguishing robot with the ability to detect human presence in the area even when there is fire. Multiple sensors are utilized in this study to detect nearby flame, smoke, temperature and humidity, and obstacles through integration with Arduino and Raspberry Pi. The proposed robot is remotely controlled by the user over Wi-Fi through the graphical user interface created by the researchers in Python for easy monitoring of data and control. A camera is also mounted to the robot for surveillance purposes. The human detection system of the robot is implemented through using ultra-wide band radar (UWB) by utilizing the X4M300 presence sensor, which could detect human presence based on their respiration movement. Initial testing and four experiments were conducted to test the radar sensor's capabilities compared to the existing methods of human detection. The researchers yielded an accuracy of 97.29% in the testing of human detection system, proving that the implementation of UWB radar sensor is successful.

Lightness signal and color reflectance constitute the reflected luminance spectra from camera captured image to camera lenses. The intensity of lightness and visible RGB signals deviates as the camera distance to object varies. The presence of uneven distribution of photosynthetic light causes angular light effect of shadowing on the focal object and light emitting objects placed on the visually noisy background added a challenge in materializing an efficient greenness index for crop phenotyping. The proposed method in this study compensates excessive relative brightness on the image by introducing lightness rectification coefficient and employing genetic algorithm to derive a novel visible tetrahedron greenness index (gvTeGI) based on normalized green waveband. Hybrid neighborhood component analysis and Pearson’s correlation coefficient approach for feature selection resulted to retaining photosynthetic canopy area, and correlation and homogeneity texture features as highly important descriptors for biophysical signatures considered in this study which are lettuce fresh weight, height and number of spanning leaves. The selection, crossover and mutation rates used to optimize the genetic algorithm model are 0.2, 0.8 and 0.01 respectively. Indoor and outdoor aquaponic system was deployed for 6-week full crop life cycle cultivation. Regression machine learning models were used to estimate biophysical signatures from extracted gvTeGI channels. Optimized Gaussian processing regression model bested regression support vector machine and regression tree in estimating fresh weight, height and number of spanning leaves with R2 values of 0.7939, 0.7662 and 0.7446. The proposed gvTeGI proved to be more accurate than previously published greenness index for the estimation of biophysical signatures of lettuce using consumer-grade RGB camera.

An emerging subsynchronous oscillation (SSO) associated with wind generators and voltage-sourced converter (VSC) based HVDC has been observed around the world. It is revealed that this new type of SSO is caused by the subsynchronous control interaction among power electronic converters and the grid. In this paper, the stability criterion of SSO is examined using frequency-dependent impedance models. Then a shunt VSC based subsynchronous damping control (SVSDC) has been proposed to reshape the impedance characteristic of the whole system and thus mitigate the SSO. The stability criterion and the control has been applied to a typical system with DFIG-based wind farms connected to a modular multilevel converter (MMC) based HVDC transmission. Impedance model based analyses as well as electromagnetic simulations have verified the effectiveness of the criterion and the control scheme. For its flexibility of capacity and deployment, the proposed SVSDC offers a promising option to address the SSO issues associated with wind generators and/or VSC-HVDCs.

For the operational safety and stability of electrical system, effective power flow control in meshed high voltage direct current (HVDC) grids makes sense. In order to realize the objective of controlling several lines simultaneously and independently in a convenient way, interline dc power flow controller (IDCPFC) has been introduced. To cover some shortages of present IDCPFC topologies, an improved triple interline dc power flow controller (TI-DCPFC), capable of controlling power flow of two lines actively, has been proposed in this paper. To explain it thoroughly and explicitly, its operational principle is illustrated combined with the mathematic equations firstly. Then, to validate its capacity of dealing with occasions of bidirectional flows and the dual-freedom control function, the theoretical control strategy and simulation results in a typical working mode are referred to comprehensively.

This paper shows the design, construction, and implementation of an Automated Aquaponics system. Most of the commercial aquaponics system in the Philippines is grid-dependent thus making it cost-ineffective. The design of the system has three-part, hydroponics, aquaculture, and control systems. The design consists of a hybrid power supply that allows operation dependent on the grid or PV installations. Aside from integrating it to be partially dependent on renewable energy, the system was designed to adapt and adjust the monitored environment to be more habitable for the aquaculture. Through the use of relays, dump energy is also observed. Through the real-time monitoring system, the design allows users to record and system’s condition, power, energy consumption, and power supply dependency simultaneously.

The evolution of Software Defined Networks (SDN) and Network Function Virtualization (NFV) introduced a revolutionary development in network architecture. SDN together with NFV provides users a platform to design flexible virtual networks (VNs) on a shared computer infrastructure. However, network administrators have specific requirements to secure this network. There are new security demands for VN such as flexible network function migrations and user-focused security system, which may not be supported by traditional firewalls. In our work we have implemented SDN and NFV based firewalls on an open source platform mininet. POX module and Click Modular Router are used to develop our firewall modules. Then we evaluated the performance of both firewalls with packet loss and throughput measurement.

Nowadays, it is convenient to gain new knowledge and skills by learning from the internet. However, some contents may be hard to understand just by reading texts. Photography knowledge is one of those, in which learner may need a large amount of time and cost to practice it. Therefore, this paper provides an alternative way of a game-based learning tool. It simulates a camera into a game combining with a story and some challenges of engagement. It is designed such that a photography knowledge can be delivered to learners through this developed game. To validate this assumption, 25 participants are asked to join our experiment. They are asked to do a pre-test, play our game, and do a post-test. Then, they are asked to answer questionnaires regarding effectiveness and benefits of the proposed game. It is shown that the participants could improve their scores from the pre-test of 44% to the post-test of 89%, regarding the understanding of photography knowledge. Also, the questionnaires’ results show that our game could help the participants to gain the knowledge.
