Sentiment classification is an instrument used for predicting stock price movement. This paper presents a comparison of sentiment classification performance using machine learning techniques consisting of the Naïve Bayes classifier and support vector machine (SVM) to provide a positive, neutral, or negative sentiment in Thai FinTech news and opinions on the tweet corpus. Accordingly, machine learning algorithms are employed to analyze how tweets correlate with stock market price behavior. Finally, the actual and prediction errors are examined by evaluating classifier performance. The results show that the Support Vector Machine has a better performance than the Naïve Bayes classifier.
情绪分类是一种预测股票价格走势的工具。本文介绍了使用由Naïve贝叶斯分类器和支持向量机(SVM)组成的机器学习技术对泰国金融科技新闻和推文语料库上的观点提供积极,中立或消极情绪的情感分类性能的比较。因此,机器学习算法被用来分析推文与股票市场价格行为的相关性。最后,通过评估分类器的性能来检验实际误差和预测误差。结果表明,支持向量机比Naïve贝叶斯分类器具有更好的性能。

This paper presents a new simply full-wave rectifier in voltage and current mode employing two second generation current conveyors (CCIIs) that can be programmed. The different of bias currents has been used for the CCIIs operating. They are biased currents that are used to controlled by on-off, the so call “current conveyor analog switches (CCASs)”. So, the different of bias currents is used to control the output by programme that the input alternative voltage and current signal is supplied. They will be rectified into two symmetrical voltage and current outputs. The proposed full-wave rectifier can be simultaneously realized to full-wave in voltage and current modes. The proposed full-wave rectifier circuit has been simulated using 0.18 μm CMOS from TSMC. The simulation results are used to confirm the workability of the proposed circuit.

Vehicle routing problems play a critical role in logistics distribution, allowing companies to minimize operational parameters such as cost, fuel consumption, emissions etc. This paper studies a customized vehicle routing problem incorporating nighttime delivery options for a heavily congested urban area. The aim is to identify the optimal combination of day and night routes by trading off between fuel and staff costs. A Linear Programming (LP) formulation for the Night Time Vehicle Routing Problem (NTVRP) is introduced. The model is then applied to a case study using real data from a department store in Bangkok, Thailand. A fuel consumption model is used alongside an emission model to estimate the beneficial impact of NTVRP on both costs and emissions. Results show that when demand is high and 55 tonne heavy goods vehicles are used, the cost savings are about 16.7 percent. More significantly, CO2 emissions are reduced by more than 30 percent. With low demand, cost savings are more than 30.8 percent, together with a 28.2 percent reduction in CO2 emissions. Overall, the case study shows that nighttime delivery is a viable option to increase efficiency and sustainability of a logistics company.
车辆路线问题在物流配送中起着至关重要的作用,使公司能够最大限度地减少运营参数,如成本、燃料消耗、排放等。本文研究了一个针对严重拥堵的城市地区,包含夜间送货选项的定制车辆路线问题。其目的是通过在燃料和人员成本之间进行权衡,确定白天和夜间路线的最佳组合。介绍了夜间车辆路径问题(NTVRP)的线性规划(LP)公式。然后将该模型应用于使用泰国曼谷一家百货商店的真实数据的案例研究。同时使用油耗模型和排放模型来估计NTVRP对成本和排放的有利影响。结果表明,当需求高时,使用55吨重型货车,成本节约约16.7%。更重要的是,二氧化碳排放量减少了30%以上。在低需求的情况下,成本节约超过30.8%,二氧化碳排放量减少28.2%。总的来说,该案例研究表明,夜间配送是提高物流公司效率和可持续性的可行选择。

This survey design aims to examine financial literacy, which is a matter of concern in Thailand. The conceptual gamification design in this study aims to illustrate the impact of positive feedback during game activities on players' behavior. Gamified activities are designed to provide positive feedback by using a saving and expense financial activity. This positive feedback will persuade players to change their financial behavior. The significance of the financial literacy findings are positive, implying that the higher the level of the satisfaction about their financial plan and financial knowledge, the more likely it is that it will affect their behavior. This is a working research to apply the gamification workflow which encourages people to live their lives with advanced technology.
这个调查设计的目的是检查金融素养,这是一个问题的关注在泰国。本研究的概念游戏化设计旨在说明游戏活动中积极反馈对玩家行为的影响。游戏化活动旨在通过使用节省和费用的财务活动来提供积极的反馈。这种积极反馈将说服玩家改变他们的财务行为。理财素养调查结果的显著性为正,表明对理财计划和理财知识的满意度水平越高,越有可能影响其行为。这是一个应用游戏化工作流程的工作研究,鼓励人们用先进的技术生活。

Accurately forecasting fine particulate matter of less than a 2.5 micrometer diameter (PM2.5) concentration levels is important to better manage the air pollution situation and to give advance warnings to residents and officials. In this paper, a Long Short-Term Memory (LSTM) deep neural network model and a Seasonal AutoRegressive Integrated Moving Average with eXogenous regressor (SARIMAX) were trained on air quality and meteorological time series data at the Chokchai metropolitan police station area in Bangkok from 2017 to 2018. After figuring out the best configuration of both algorithms, the performance of the LSTM model to predict PM2.5 concentrations for 24 hours was evaluated and compared against the SARIMAX model. Our experiments indicated that LSTM had a better prediction accuracy as indicated by the RMSE and MAE values for each of the time steps. LSTM could forecast one hour ahead at a very low RMSE of 3.11 micrograms per cubic meter on average, and a MAE of 2.36 micrograms per cubic meter on average, while SARIMAX errors were more than doubled. When the time steps were farther apart, the number of errors were higher for both models.
准确预测直径小于2.5微米的细颗粒物(PM2.5)浓度水平对于更好地管理空气污染状况以及提前向居民和官员发出警告非常重要。本文采用长短期记忆(LSTM)深度神经网络模型和带有外生回归因子的季节性自回归综合移动平均(SARIMAX)模型,对2017 - 2018年曼谷Chokchai大都会派出所空气质量和气象时间序列数据进行了训练。在确定了两种算法的最佳配置后,对LSTM模型预测24小时PM2.5浓度的性能进行了评估,并与SARIMAX模型进行了比较。我们的实验表明,LSTM在每个时间步长的RMSE和MAE值都具有更好的预测精度。LSTM可以提前一小时预测,平均RMSE为3.11微克/立方米,MAE为2.36微克/立方米,而SARIMAX误差增加了一倍多。时间步距越远,两种模型的误差数越高。

This study is an extension of our another research entitled “Using Process Mining for Predicting Relationships of Couples Sitting on a Sofa”, whereas the 5 most frequent/possible sitting positions for Happy Couples were identified/discovered as well as the 2 most frequent/possible sitting positions for Unhappy Couples. The main focus and emphasis of the current work is on Speech Behavior Analysis of the both Happy and Unhappy Couples, for each of the above-discussed sitting positions, in a semantic approach. To do this, 8 semantic keywords (i.e., in order to convey/represent the emotional status of the verbal words and phrases exchanged between the couples) were initially defined, and two Process Mining (process discovery) techniques/algorithms were later applied on the (previously collected) Sofa Data as the following: (1) Social Network Miner algorithm (based on the Subcontracting metric) supported by the ProM 6 Package Manager. (2) Fuzzy Miner algorithm (via frequency-based metric) supported by the Disco Fluxicon. Accordingly, the results showed that the occurrence of the keywords “Happy”, “Excited”, “Satisfied” and “In Love” was more frequent/possible in the following sitting positions: “Cuddling in the middle”, “Cuddling in the corner, “Side-by-Side (touching without cuddling)”, “Corner cuddle with tucked leggs” and “Legs on lap”. Alternatively, the occurrence of the keywords “Irritated”, “Sad”, “Angry” and “Worried” was more frequent/possible in the following sitting positions: “Opposite sides of the sofa” and “Sat on different sofas”. This study provides groundwork for further and future studies.
这项研究是我们另一项名为“使用过程挖掘来预测坐在沙发上的夫妇的关系”的研究的延伸,而快乐夫妇的5种最常见/可能的坐姿被确定/发现,而不快乐夫妇的2种最常见/可能的坐姿被确定/发现。当前工作的主要焦点和重点是对上述每种坐姿的快乐和不快乐夫妇的言语行为分析,采用语义方法。为此,最初定义了8个语义关键字(即,为了传达/表示夫妻之间交换的口头单词和短语的情感状态),随后在(先前收集的)沙发数据上应用了两种过程挖掘(过程发现)技术/算法,如下所示:(1)由ProM 6 Package Manager支持的社交网络挖掘算法(基于分包度量)。(2) Disco Fluxicon支持的Fuzzy Miner算法(基于频率的度量)。结果显示,“快乐”、“兴奋”、“满意”、“恋爱”等关键词在以下坐姿中出现的频率更高:“中间拥抱”、“角落拥抱”、“并排拥抱(不拥抱)”、“蜷腿拥抱”和“腿放在膝盖上”。另外,“烦躁”、“悲伤”、“愤怒”和“担心”等关键词在“沙发的两侧”和“坐在不同的沙发上”的坐姿中出现的频率更高。本研究为进一步的研究奠定了基础。

The main focus and emphasis of the current work is on Speech Behavior Analysis of the both Happy and Unhappy Couples, for each of the above-discussed sitting positions, in a semantic approach. To do this, 8 semantic keywords (i.e., in order to convey/represent the emotional status of the verbal words and phrases exchanged between the couples) were initially defined, and two Process Mining (process discovery) techniques/algorithms were later applied on the (previously collected) Sofa Data as the following: (1) Social Network Miner algorithm (based on the Subcontracting metric) supported by the ProM 6 Package Manager. (2) Fuzzy Miner algorithm (via frequency-based metric) supported by the Disco Fluxicon. Accordingly, the results showed that the occurrence of the keywords “Happy”, “Excited”, “Satisfied” and “In Love” was more frequent/possible in the following sitting positions: “Cuddling in the middle”, “Cuddling in the corner, “Side-by-Side (touching without cuddling)”, “Corner cuddle with tucked leggs” and “Legs on lap”. Alternatively, the occurrence of the keywords “Irritated”, “Sad”, “Angry” and “Worried” was more frequent/possible in the following sitting positions: “Opposite sides of the sofa” and “Sat on different sofas”. This study provides groundwork for further and future studies.","PeriodicalId":442255,"journal":{"name":"2019 17th International Conference on ICT and Knowledge Engineering (ICT&KE)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131967355","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}

The use of biometric data for authentication in a networked environment brings both security guarantee and fear to many. It poses strong authentication because of its uniqueness; however, unlike passwords and smartcards, biometric information is non-repudiable. Therefore, it should be treated with utmost confidentiality and protection. Authentications hould be improved further because as people and machines advances the designs of security approaches and mechanisms, the threat increases in volume and variability also. In this paper, a dynamic third-factor authenticator for Biometric Authentication Systems is proposed. Not only that it protects biometric information, it also possesses the quality of dynamism that ensures security by addressing the threat before it takes place. This proposed enhancement follows the standards and guidelines prescribed for digital identity and data security.
在网络环境中使用生物识别数据进行身份验证给许多人带来了安全保障和恐惧。它的唯一性使其具有强认证性;然而,与密码和智能卡不同,生物识别信息是不可否认的。因此,它应该得到最大程度的保密和保护。身份验证应该得到进一步改进,因为随着人和机器改进安全方法和机制的设计,威胁的数量和可变性也在增加。本文提出了一种用于生物特征认证系统的动态第三因素认证器。它不仅保护生物特征信息,还具有动态特性,通过在威胁发生之前解决它来确保安全。这项建议的加强符合数码身份和数据保安的标准和指引。
