基于条件随机场的泰语音节切分方法

音节是泰语构词和读音的基本单位,泰语音节切分对泰语词法分析、语音合成、语音识别研究具有重要意义。结合泰语音节构成特点,提出基于条件随机场(Conditional Random Fields)的泰语音节切分方法。该方法结合泰语字母类别和字母位置定义特征,采用条件随机场对泰语句子中的字母进行序列标注,实现泰语音节切分。在InterBEST 2009泰语语料的基础上,标注了泰语音节切分语料。针对该语料的实验表明,该方法能有效利用字母类别和字母位置信息实现泰语音节切分,其准确率、召回率和F值分别达到了99.115%、99.284%和99.199%。

Comparative analysis of public participation in the EIA process for Thai overseas investment projects: Krabi coal terminal,Hongsa coal power plant,and Dawei special economic zone

While Thai overseas investment projects (TOIPs) have become a key form of development in the region, their environmental impact assessment (EIA) quality has been criticized. This research sought to analyze the differences in EIA practices in terms of public participation (PP) in two TOIPs – the Hongsa coal-fired power plant (Lao PDR) and the Dawei special economic zone (Myanmar) – versus a national-level project, the Krabi coal terminal. For Laos and Myanmar, which did not previously require PP, the Thai consultants did not apply the Thai PP framework, leading to poor public participation index (PPI) scores = 0.02, indicating a negligible PP process. However, the consultant on the Krabi coal terminal claimed to abide by the Thai regulations, yet the PPI scores claimed = 0.81 (substantive rationale), were quite different from those indicated by the affected villagers = 0.39 (instrumental rationale). These villagers’ concerns resulted in conflict between the affected villagers and project owners. Our findings have revealed the true necessity of PP regulation and systems to monitor consultant performance to ensure sustainability of TOIPs in neighboring countries.     

Business models and financing options for a rapid scale-up of rooftop solar power systems in Thailand

Diverse solar PV business models and financing options exist in the international landscape, helping expand and accelerate the adoption of rooftop solar PV systems. The conditions for their emergence are context specific, depending on the policies, regulations, incentives, and market conditions of each country. After a review of the international landscape, this paper compiles and analyzes business models and financing options for rooftop solar PV investment in Thailand that have emerged during the period between 2013 and 2015. Despite policy discontinuity for the support of rooftop solar systems, diverse business models and financing options are driving market expansion and expanding solar access to more Thai consumers. Drawing on our policy and regulatory analyses and in-depth interviews with business representatives, we identify four types of business models and one financing option. The business models include Roof Rental, Solar PPA, Solar Leasing, and Community Solar, and the financing option is the solar loan. We analyze the drivers for their emergence, barriers to their success, and the risks from the business owners' and consumers' viewpoints. Our policy recommendation is focused on crafting a net-metering regulation with evidence-based studies on the potential costs and benefits to different stakeholders.     

Accommodating the discarnate: thai spirit houses and the phenomenology of place

ABSTRACT

In Thailand, many homes possess small shrines for locality and guardian spirits. In Thai the shrines are known by various names denoting the ethereal occupants and their various spheres of influence. In English they are referred to collectively as “spirit houses.” By exploring the ways in which these shrines are used by Thai people through two case studies, this article addresses the prevalence of spirit houses in contemporary urban locations, an area which scholarship on Thai popular religion has largely neglected. Based upon eighteen months of fieldwork in three Thai cities, the article argues that the ornate shrines which adorn many house compounds in contemporary urban Thailand tie into local understandings of the social character of places. It is suggested that the persistence of spirit houses can be partly understood through their roles as mediators of the phenomenological experience of certain places. Spirit houses are one part of a gathering process that imbues places with significant meaning. The shrines exemplify that culturally specific interactions and engagements with spirits associated with certain places influence how the phenomenological qualities of these places are constructed and experienced.     

Antibacterial activity of extracts from some edible plants commonly consumed in Asia

Extracts of edible plants (26 species) from China, Japan, Thailand and Yemen were screened for their antibacterial activity against Bacillus cereus, Staphylococcus aureus, Listeria monocytogenes, Escherichia coli and Salmonella infantis. Buffered methanol (80% methanol and 20% PBS) and acetone extracted inhibitory substances against tested bacteria from 16 plants, as revealed by the disc assay. The minimum inhibitory concentrations (MICs) of extracts determined by the agar dilution method ranged from 165 to 2640 mg l⁻¹. The most sensitive microorganism to extracts from Azadirachta indica, Cinnamomum cassia, Rumex nervosus, Ruta graveolens, Thymus serpyllum and Zingiber officinale was B. cereus, with MIC of 165 to 660 mg l⁻¹. E. coli and S. infantis were only inhibited by Cinnamomum cassia extracts at the highest MIC (2640 mg l⁻¹). L. monocytogenes (Tottori) was more resistant than the ATCC 7644 strain to extracts from Ruta chalepensis, Artemisia absinthium and Cissus spp. EDTA (0.85 mM) reduced the MICs of Cinnamomum cassia and Cissus rotundifolia by at least 50% when tested against E. coli, S. infantis, S. aureus and L. monocytogenes.     

融合人名知识分布特征的汉泰双语人名对齐

双语人名对齐方法研究直接影响到跨语言信息处理的效果,由于泰语与汉语的发音差异大,汉泰双语平行语料库资源有限,基于统计的音译人名对齐模型难以解决汉泰双语人名对齐问题,提出一种在音译特征基础上融合人名知识分布特征相似性的汉泰双语人名对齐方法。计算双语人名音译相似度特征,通过卡方检验等计算汉语人名与泰语人名的知识分布相似度特征,借助支持向量机学习汉泰人名翻译对的两种特征生成人名翻译对分类器,对分类器分类结果调优生成对齐结果。实验结果表明该方法在汉泰人名发音差异大和缺少双语语料资源支持的情况下取得了较好效果。

Management of Concurrent Engineering: Organizational Concepts and a Framework of Analysis

ABSTRACT

This article examines the concept of concurrent engineering and presents a framework for evaluating its management. The key organizational concepts for managing new product development are first analyzed from a historical perspective. The concurrent engineering approach to new product development is then contrasted with both the traditional sequential and the more recent overlapping problem-solving approaches. Finally, a model for managing current engineering is presented. The model consists of five critical components that may be used by engineering managers for guiding the implementation of their concurrent engineering efforts.
