One of the crucial part in the development of machine vision for rice seed identification are the design of the seed holder itself. In this project, seed holder was designed to hold rice seed for image acquisition purposes. Four different colors such as black, blue, green and red was painted on the seed holder. Effect of background colors on rice seeds image segmentation were tested under machine vision setup. Simple rice seed parameters such as seed length and width were measured using image processing technique programmed in LabVIEW software. Percentage error for each background color was calculated based on the actual length and width of the rice seed. Blue background color was found to provide good contrast for estimation of length and width with accuracy less than 2% and 5%, respectively.

Electrochemically deposited conducting polymer polyaniline (PANI) electrochromic films were deposited onto the indium tin oxide (ITO) coated glass electrodes and their electrochromic performances were investigated by using spectrophotometric and electrochemical methods. Optical performance of PANI film was evaluated by measuring spectroscopic signals before and after the incubation of PANI film coated electrode in ammonia and some metal ion containing solutions. The most significant alteration of electrochromic effect was observed after an incubation of PANI/ITO-modified electrode in Cu(II) ion containing solution. The conditions at which the PANI films exhibit the highest optical contrast have been determined. Applicability of PANI/ITO-electrodes for electrochromic effect-based determination of Cu(II) ions has also been discussed.

Selection of Morphological Features in Classifying Weedy Rice and Rice Seed Varieties using Discriminant Function Analysis

引用

IOP Conference Series: Materials Science and Engineering 2019年第1期557卷

作者： R Ruslan S K Bejo I H Rukunuddin A A Aznan Department of Biological and Agricultural Engineering Universiti Putra Malaysia UPM 43400 Serdang Selangor Malaysia School of Bioprocess Engineering Universiti Malaysia Perlis UniMAP 02600 Arau Perlis Malaysia Center of Excellence for Advanced Sensor Technology (CEASTech) Universiti Malaysia Perlis UniMAP 02600 Arau Perlis Malaysia

A comparison on classification accuracy and morphological features selection between stepwise discriminant function analysis (DFA) and enter all variables DFA were made for classification of Malaysian rice seed varieties namely MR297, MR263, MR284, MR219 and a group of weedy rice. Eighteen morphological features were used for the discriminant analysis. The classification accuracies of MR297 and MR263 against weedy rice group were maintained at 99.1% and 98.9% respectively, either using stepwise DFA or normal DFA. The classification accuracy for MR284 decrease from 95.0% to 93.7% using stepwise DFA with the reduction to five morphological features selected in the analysis. However for MR219, the classification accuracy increased by 0.3% using optimized features in stepwise DFA. Thus it can be concluded the optimization of morphological features through stepwise DFA classification does not necessarily increase the accuracy for discriminating weedy rice and Malaysian rice seed varieties.

Glucose determination in neonates require painful blood draws. Our group has been developing a painless, noninvasive method of collecting glucose passively diffusing through the skin. The transdermal glucose collected in this manner has a concentration in the uM range. Here we describe a fiber optic biosensor based on the glucose binding protein (GBP) labeled with either BAD AN or acrylodan and immobilized on Ni-NTA agarose beads. The portable, low-cost biosensor system consists of an optical fiber with the sensitized beads trapped on one end, and appropriate optics and electronics on the other end. The control software and the visual interface for the optical sensor is designed and implemented in Lab VIEW and runs on a tablet computer. To collect the transdermal glucose, an automated system with a sampling head attaches to the skin surface and executes a wash, dry and sampling protocol. Data collected from several human subjects using our noninvasive glucose monitoring system are presented.

Atomistic spin dynamics simulations of the MnAl τ-phase and its antiphase boundary

In this work we develop an atomistic spin dynamics model for the ideal Mn50Al50τ-phase by means of first-principles calculations. The model is applied to study the domain wall and antiphase boundary phenomenology. In particular, it allows us to obtain the dependence on the interfacial exchange coupling of the nucleation and depinning fields, as well as the macroscopic magnetization profile across the antiphase boundary. We find that microscopic antiferromagnetic exchange coupling stronger than 10meV could unavoidably lead to the formation of a domain wall at the antiphase boundary.

Collective measurements on identically prepared quantum systems can extract more information than local measurements, thereby enhancing information-processing efficiency. Although this nonclassical phenomenon has been known for two decades, it has remained a challenging task to demonstrate the advantage of collective measurements in experiments. Here, we introduce a general recipe for performing deterministic collective measurements on two identically prepared qubits based on quantum walks. Using photonic quantum walks, we realize experimentally an optimized collective measurement with fidelity 0.9946 without post selection. As an application, we achieve the highest tomographic efficiency in qubit state tomography to date. Our work offers an effective recipe for beating the precision limit of local measurements in quantum state tomography and metrology. In addition, our study opens an avenue for harvesting the power of collective measurements in quantum information processing and for exploring the intriguing physics behind this power.

Outdoor localisation can offer great capabilities in security and perimeter surveillance applications. The localisation of people become more challenges when involving with the nonlinear environment. GPS and CCTV are two localisation techniques usually use to localise human in an outdoor environment. However, they have weaknesses which result in low localisation accuracy. Therefore, the application of Device-free localisation (DFL), together with the Internet of things (IoT) is more appropriate due to their capability to detect the human body in all environmental conditions, and there is no problem losing signals as faced by GPS. This system offers excellent potential in humans localisation because humans can be detected wirelessly without any tracking device attached. In developing the DFL system, the main concern is the localisation accuracy. Although the existing DFL system gives significant result to the localisation, the accuracy is still low due to the large variation in RSSI values. Hence, a Radio Tomographic Imaging-based ANN classification (RTI-ANN) approach is proposed to increase the localisation accuracy. This Artificial Neural Network (ANN) is designed to learn the Radio Tomography imaging (RTI) input for classification purpose. Even though the RTI gives a good result to the localisation, however, it suffers from smearing effect. To eliminates this smearing area and background noise, pre-processing of the RTI image is required. Thus, extracting the valuable information technique from the RTI image has been proposed. By extracting the valuable information data from the RTI image, about 61% to 66% of the smearing noise is removed depending on the size of the RTI image. Only data directly associated with human attenuation used for training and learning of ANN. The experimental results show ANN system can localise human in the right zone for a given dataset.
