No full textNowadays, Mobile Banking (MB) Systemis performing of finance related functions on amobile device. MB can be used anywhere youtake your device and fast banking today. CurrentMB confidentiality and authentication arechallenging and then identified as major securityrisks. In this paper, MB system is implemented onconfidentiality, authentication and verification ofsecurity channels to protect the system’s securityrisks. To protect the confidentiality andauthentication,PIN (Personal IdentificationNumber) number is encrypted by RC5 encryptionalgorithm in MB system. Then, CAPTCHA imagegrid view used to protect the verification.Therefore, this system can fulfill not only therequirement of the security of mobile user but alsothe security of banking database system

Effects of Nitrogen Fertilizer Rates on Yield and Yield Components of Maize (Zea mays L.)
No full textMaize is one of the most important cereal crops in the world. To investigate the effects of nitrogen fertilizer rates on growth and yield of maize and to determine the suitable nitrogen fertilizer rate, an experiment was conducted by using Randomized complete block design (RCBD) with four replications at Shwe Baho village, Zayarthiri Township, Nay Pyi Taw in post monsoon season and monsoon season. The treatments were T1 (no nitrogen application), T2 (90 kg N ha-1), T3 (120 kg N ha-1), T4 (150 kg N ha-1) and T5 (180 kg N ha-1) treatments. The tested maize variety was pacific-789 hybrid. According to the results, application of nitrogen gave the significant effect on grain yield and yield components of maize in both seasons. The superior maize yield was observed in all nitrogen treatments compared to control. The use of the highest nitrogen fertilizer rate (180 kg N ha-¹) in T5 gave the significant highest grain yield (7696.6 kg ha-¹) in post monsoon season and (8764.5 kg ha-¹) in monsoon season, respectively. In both seasons, the grain yield in T5 treatment was significantly increased about 62% over T1 treatment. Therefore, the application of nitrogen with the rate of T5 (180 kg ha-1) might be the appropriate rate to maximize the maize production. Considering the increased grain yield of the hybrid maize, nitrogen rate of T5 (180 kg ha-1) could be achieved in this study area
Histological Changes in the Gill Tissues of Oreochromis sp. from Naung Tong Lake, Kyaing Tong
No full textNaung Tong Lake was chosen as the study area to conduct the present research from June, 2017 to March, 2018. Naung Tong Lake is located in Kyaing Tong Township. Water is stored in this lake within an area of 2414.02 m in length and about 600 m in width. Presently, cyanobacterial bloom and water pollution are found in Naung Tong Lake by anthropogenic activities. In the present study, some cyanobacteria, Microcystis spp. were observed in four sample collection sites in Naung Tong Lake. Microcystis spp. are toxic cyanobacteria and can produce bioactive compounds that may be harmful called cyanotoxins. Fish specimen, Oreochromis sp. was used for histological investigations. The occurrences of histological changes in gill tissues of fish, Oreochromis sp. were recorded. Histological changes in gills were epithelial lifting, epithelial separation, dilation of gill filaments with blood congestion, incomplete and complete fusion of lamellae, shortening of lamellae, hyperplasia, curling the lamellae, necrosis, elastic cartilage and deformed structure of gill. Histological changes in gill tissues of studied fish revealed metabolic disturbance and cellular disorder due to environmental contaminations, toxic cyanobacteria, Microcystis spp. and water pollution in Naung Tong Lake
Unsupervised Neural Machine Translation between Myanmar Sign Language and Myanmar Language
No full textThis paper investigate the utility of unsupervised Neural Machine translation (U-NMT) on low-resource language pairs: Myanmar sign language (MSL) and Myanmar language. Since state-ofthe-art neural machine translation (NMT) require large amount of parallel sentences, which we do not have for pairs we consider. We focus primarily on incorporating two different types of monolingual data: translated Myanmar sentences of primary English and myPOS data, only into our Myanmar language side. We found that the incorporating monolingual data achieved higher performance than the baseline approach. We prepared four types of training data for U-NMT models and the results clearly show that using the myPOS corpus on incorporating the Myanmar language monolingual data achieved the
highest BLEU scores when compared to other training data
Study on Processing of Rare Earth Oxide from Monazite, Mongmit Myitsone Region
No full textThe present study investigates to support the production of rare earth oxide, which has been used for next research work of individual rare earth elements purification process from monazite, Mongmit Myitsone Region. The processing of rare earth oxide in this study involves four main parts, digestion of monazite concentrate, selective precipitation of rare earth hydroxide, precipitation of rare earth oxalate and calcination of rare earth oxide. The chemicals used in this study were commercial grade from local market. The products from each processing process were characterized by XRD and XRF. The final product contained (> 95 %) of total rare earth oxide and fulfilled to apply next purification process. This paper review the cheaper and easily way to extract rare earth oxide from Myanmar monazite
Study on the Treatment of Liquid Waste from Rare Earth Processing by Chemical Precipitation
No full textThis paper describes treatment of liquid waste from rare earth processing by chemical precipitation. Monazite ore from Moemeik Myitsone area was used as raw material for rare earth processing. Large amount of solid and liquid wastes were generated after rare earth oxide processing. Solid waste was stored in the storage tanks and liquid waste needed further treatment before discharges to the environment. Research process serves the purpose of reducing the volume of the waste as much as possible to protect men and the environment from any undesirable effects for the present and future generation. Treatment methods are selected based on the composition, quantity and form of the waste materials. The used method is chemical precipitation method. For liquid waste treatment, the most coagulation treatment used is the Fe +++ co-precipitation followed by settling, decantation and filtration of the supernatant liquid. The efficiency of the process can be improved by careful control of the pH and the settling the decantation procedure. The sludge was filtered, dried in oven and collected in plastic bags and temporary stored in 100 liters plastic drums. Finally all of the decontaminated effluents are safety discharged to the environment. All of the experiments were analyzed by the X- ray Fluorescence Spectrometer (XRF). Before treatment, thorium and uranium contained <2000 ppm, < 300 ppm and this is in the low level waste. After treatment result in decant water gives uranium (< 1 ppm) and thorium (< 10 ppm).According to the threshold limits for the UK radioactive classification system, liquid waste from rare earth processing was less than (0.4 Bq/g) and this range is in exempt waste and can be discharge to drain and to the environment safety. The safety regime was in place and improved simultaneously by survey monitoring by using Alert Monitor 4 meter Scale in USV/H
Neural Machine Translation between Myanmar Sign Language and Myanmar Written Text
No full textWe explore Neural Machine Translation (NMT) between Myanmar Sign Language (MSL) and Myanmar Written Text (MWT). Our developing MSL-MWT parallel corpus was used and the experiments were carried
out using three different NMT approaches: Recurrent Neural Network (RNN), Trasformer, and the Convolutional Neural Network (CNN). In addition, four different segmentation schemes for word embedding
were studies, these were syllable segmentation, word segmentation (sign unit based word segmentation for MSL), SentencePiece and the Byte-Pair-Encoding (BPE). The results show that the highest quality NMT and Statistical Machine Translation (SMT) performances
were attained with syllable segmentation for both MSL and MWT. We
found that Transformer outperformed both CNN and RNN for MWT-to-MSL and MSLto-MWT translation tasks
