Fruit or plant recognition is a very pragmatic and specific application of deep-learning technique. As compared to conventional method, the technique requires a larger quantity of data for training while at the same time promises a higher level of accuracy. Among various classes of neural network, convolutional neural network (CNN) is arguably the most commonly used method in image classification. The aim of this research work is to develop an effective method to classify the various cultivars of Durio zibethinus (or commonly known as durian) based on the crop's visual features via the application of CNN to improve the accuracy and speed of the cultivars recognition. Meanwhile, a reliable database consisting of labelled durian cultivars has been created. A total of 800 images consisting of the bottom view of 3 classes of cultivars and non-durian images are used during the training process of the neural network. The research work starts with the pre-processing and conversion of the images then followed by one-hot labelling of the data, construction of the network architecture, training and validation of the model then lastly exporting the trained model for general application. Important system parameters and prediction accuracy are obtained, including the graphs of loss function and accuracy against the number of epochs, confusion matrix, miss-classified images, the effect of network architecture on prediction performance, etc. The prediction accuracy of the trained model on the perfect bottom-view images of Durio zibethinus is 82.50%. With the addition of non-durian images, the prediction accuracy is slightly dropped to 81.25%.

In this research, a new method for stabilizing non - minimum phase (NMP) system using Active Disturbance Rejection Control (ADRC) is proposed. The general ADRC maintains stability by determining the observer poles and the controller poles, but the non-minimum phase system is very delicate as the stable bandwidth is very limited. Most research using ADRC is the minimum phase system. Therefore, the proposed method is to easily obtain controller gain with a linear quadratic regulator (LQR) using an extended system including ADRC. This widens the range in which the system becomes stable, and can determine the responsiveness of the system with only the adjustment parameter. Further, by obtaining the condition for stabilizing, the system can be stabilized easily. After designing the system design method as the proposed method, the condition is shown for the system to stabilize. Finally, the effectiveness of the proposed method is verified through simulation experiments.

Infant mortality rate in India for the year 2016 is 34 per 1000 live births. Infant mortality in rural areas is tremendously high compared to mortality in urban areas. Infant mortality refers to the death of infants and children under the age of five or between ages of one month to four years. Main reason for the death of infants is the need of the health services. Many factors lead to the mortality. One of the main reasons is high temperature. People with limited literacy in rural areas won't be able to understand complex and numerical parameters of temperature. So it is required to build an infant temperature alerting device which can be used by them. It uses sound and light as an indication for varying temperature levels. The device is designed to satisfy the alerting of the temperature continuously and to help people in rural areas to immediately attend. Temperature is measured using LM35 and checked for the threshold. This device can be used by the people with limited literacy using different sounds and different colors of light. The entire operation for sound and light is done by Arduino software. In addition, the temperature data is sent to the Mobile through the Bluetooth (HC05) Module. A mobile APP is created in MIT APP inventor. The data from the temperature sensor is sent via Bluetooth module to the MIT app inventor. The APP check for the conditions and if the temperature exceeds the threshold, the parent/caretaker is alerted by a voice message from the mobile and red light indication. In addition, the location of the infant is sent to the village health officer/Doctor with an alert message.

A Secure social environment can be achieved if technology can be applied smartly. Nowadays smartphones have become increasingly common. This device can be used effectively if we want to live secure and smarter lives. In this paper the approach is to increase the security of our society by taking the opportunities of technologies. This paper demonstrates the simple method where there is a smartphone application along with a small device that acts as an emergency switch button. If someone falls in danger then s/he can press that button (which is connected with the phone via Bluetooth), and it sends a message about the danger to the emergency contact of the victim and notifies the nearby users who are using this app. There is a cancel button by which victims can cancel the request for help in case of misunderstanding. The designed app along with the hardware switch works as expected. The user-friendliness and low-cost of the designed app make it more convenient than existing similar systems.

Conventional chemopreventive agents causes adverse side effects in cancer patients. Thus, this study focuses on the effects of natural plant extract against cancer cell as a way to reduce or detrimental effects of orthodox drugs. The present study emphasizes on anti-cancer potentiality of Artocarpus altilis fruit extract against cervical cancer cell. Cervical cancer cell treated with methanol extract of artocarpus altilis fruit with the concentration varied from 10µg/ml, 20µg/ml, 30µg/ml, 40µg/ml and 50µg/ml. Treated and untreated (cells without treatment) cell proliferation and half maximal inhibitory concentration IC50 measured after 72 hours of incubation. Cells without treatment, 10µg/ml, 20µg/ml, 30µg/ml, 40µg/ml and 50 µg/ml of extract concentration showed 1.3, 0.98, 0.72, 0.65, 0.51, and 0.3 of cell proliferation factor accordingly with 40µg/ml of IC50 value. The result shows that artocarpus altilis is capable in opposing cervical cancer cell proliferation or growth as the proliferation factor decreases with the increasing dose of extract concentration which can be attributed to the presence of bioactive compound in Artocarpus altilis.

In this modernized era, computer visualization is a powerful means to discover. It is used in translating from visual into digital information, analog to digital signal, and to name a few. A computer motherboard refers to a circuit board that holds the essential processing parts of a computer. Every part of the component has its own purpose, either to communicate with other component or to receive power. However, the components on a motherboard are difficult to detect due to the similarity and complexity of the design. Thus, a study of computer motherboard component recognition using a combination of texture and shape features is presented. The Gray Level Co-occurrence Matrices (GLCM) and Connected Region were implemented as the features extraction techniques. On the other hand, the classification is performed using a technique of Support Vector Machine (SVM). The computer motherboard components are classified into four components which are chipset, CPU socket, expansion slot, and memory slot. From the testing conducted, it is observed that 90% overall mean of recognition accuracy is achieved which proved that the proposed techniques are applicable for the computer motherboard component recognition.

An AC magnetometer using a resonant excitation coil is presented for magnetic nanoparticles characterization. An automatic resonant frequency switching of the excitation coil circuit is developed to reduce the measurement time and human contributed errors. A network capacitor consists of 13 different capacitance values is fabricated and controlled by using a relay module and a microcontroller. The resonant circuit of the excitation coil is resonated up to 81.36 kHz to reduce its impedance observed by a current amplifier. The impedance of the resonant excitation coil is evaluated to access the effectiveness of the resonant technique. A first-order differential coil is used to sense the magnetization from a sample and its sensitivity with respect to magnetic moment and frequency is measured. Using the developed system, we measure the complex magnetization of a multi-core iron oxide nanoparticles solution and estimated its hydrodynamic size.

With the rapid increase of file size and users, the current wireless data transfer networks are facing massive demands for channels, but if one wants to implement a RF wireless network one must pay a large fee to the government. Free space laser communication has the promise of mitigating some of these demands using line of sight implementations. OOK (On-Off Keying) is the most popular modulation scheme in free space laser communication; however, the loss of a large part of its transmitted power causes low SNR (signal to noise ratio) in this modulation scheme. This is its main drawback, which limits the maximum distance a free space laser communicator can reliably work. FSK (Frequency Shift Keying) has the advantage over OOK in terms of susceptibly to noise. In this paper we will describe the process of making an affordable free space laser communicator using BFSK (Binary FSK) concepts and commercially available off the shelf components. Because we implemented BFKS instead of OOK this communicator is inherently more resistant to noise and other interference.

OOK (On-Off Keying) is the most popular modulation scheme in free space laser communication; however, the loss of a large part of its transmitted power causes low SNR (signal to noise ratio) in this modulation scheme. This is its main drawback, which limits the maximum distance a free space laser communicator can reliably work. FSK (Frequency Shift Keying) has the advantage over OOK in terms of susceptibly to noise. In this paper we will describe the process of making an affordable free space laser communicator using BFSK (Binary FSK) concepts and commercially available off the shelf components. Because we implemented BFKS instead of OOK this communicator is inherently more resistant to noise and other interference.","PeriodicalId":147027,"journal":{"name":"2018 9th IEEE Control and System Graduate Research Colloquium (ICSGRC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128363252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
