Robust Scale-Invariant Normalization And Similarity Measurement For Time Series Data, Ariyawat Chonbodeechalermroong
Robust Scale-Invariant Normalization And Similarity Measurement For Time Series Data, Ariyawat Chonbodeechalermroong
Chulalongkorn University Theses and Dissertations (Chula ETD)
Classification is one of the most prevalent tasks in time series mining. Dynamic Time Warping and Longest Common Subsequence are well-known and widely used algorithms to measure similarity between two time series sequences using non-linear alignment. However, these algorithms work best when the time series pair has similar amplitude scaling. Unfortunately, sensor data and most real-world time series data usually contain noise, missing values, outlier, and variability or scaling in both axes, which is not suitable for the widely used Z-normalization. This research introduces the Local Feature Normalization (LFN) and its Local Scaling Feature (LSF), which can be used to …

Chulalongkorn University Theses and Dissertations (Chula ETD)
Radio Frequency IDentification (RFID) is a promising wireless object identifying technology which uses radio frequency waves to transmit data between an RFID reader and tags. The RFID systems have been effectively applied in different areas, like manufacturing, healthcare, supply chain, transportation and agriculture. Despite the vast deployment of the RFID technology in practice, the inherent RFID tag collision problem still persists as a serious concern and remains a challenge. The tag collision problem happens when some tags in reader's vicinity try to transmit data to a reader simultaneously without priori coordination. The existing RFID Electronic Product Code (EPC) Class 1 …

Gold Nanoparticles In Clp Model And Mechanism In Bone Marrows Derived Macrophages Cell For Sepsis Severity Attenuation, Sujittra Taratummarat
Chulalongkorn University Theses and Dissertations (Chula ETD)
Sepsis is still a major worldwide- public health problem as a leading cause of the high mortality rate condition. Sepsis is the inflammatory condition in host due to bacterial infections. Sepsis severity depends on the individual's immune responses and the organism virulence factor. The current strategies for sepsis treatment are based, mainly on, symptomatic treatment with antibiotics. However, the adjuvant therapy in sepsis is interesting. Gold nanoparticles are anti-inflammatory drug from the ancient time which is still currently used for the treatment of rheumatoid arthritis. Thus, we hypothesized that gold nanoparticles could be effective in reducing an inflammation in sepsis …
Microemulsion Formation Of Vegetable Oils Using Mixed Extended Surfactant For Cleaning Applications, Siriluk Jariyawattanarat
Microemulsion Formation Of Vegetable Oils Using Mixed Extended Surfactant For Cleaning Applications, Siriluk Jariyawattanarat
Chulalongkorn University Theses and Dissertations (Chula ETD)
Some vegetable oils and animal fats can form semi-solid crystalline. The formation of semi-solid fats or waxy soils results in weak interactions between the oil and surfactant during the cleaning process. In this study, the anionic extended surfac-tant (C14-15, 8PO-SO4) systems were employed to form a middle phase microemul-sion with various vegetable oils (coconut, palm and soybean oil). The addition of nonionic extended surfactant (C16-18, 2PO-4EO-OH) in the mixed surfactant systems was also evaluated to observe the solubility enhancement of oil and water phase. The IFT value of formulated surfactant systems was measured to determine the optimum salinity. The Hydrophilic-Lipophilic …

Chulalongkorn University Theses and Dissertations (Chula ETD)
The strain MAL 1HM19, a nitrate reducing and sulfur oxidizing bacteria (NR-SOB) was successfully isolated from Mae Um Long Luang hot spring from Mae Hong Son province (Thailand) using hydrogen sulfide (H2S) and nitrate (NO3-) as an electron donor and acceptor, respectively. Among the isolates of NR-SOB from different sources, the strain MAL 1HM19 was the most promising novel strain of NR-SOB because of its ability to yield ~100% H2S removal, under anoxic conditions, within 5.5 h at an initial H2S concentration of 650 ppmv. The identification of strain MAL 1HM19 based on the 16S rDNA nucleotide sequence suggests that …

Chulalongkorn University Theses and Dissertations (Chula ETD)
Synthesis of magnetic carbon nanoparticles (M-CNPs) via nebulizing co-pyrolysis of glycerol and ferrocene with magnetic induction was successfully conducted. Experimental investigation on influence of synthesizing temperature and ratio of glycerol to ferrocene suggested that at 800 °C of synthesizing temperature with an initial weight ratio of glycerol to ferrocene of 3:1, the highest M-CNP synthesizing yield of 15.9 % was achieved. With the presence of magnetic induction, controlled synthesis of M-CNPs could be anticipated as a promising method for producing M-CNPs with high quality and high yield. Oxy-tetracycline (OTC) has been recognized as environmental contamination due to its over-dosage and …

Development Of Conductive Polyimide/Polysulfone Composites As Positive Temperature Coefficient Materials, Noppawat Kuengputpong
Chulalongkorn University Theses and Dissertations (Chula ETD)
For positive temperature coefficient (PTC) applications of electrically conductive composites, volume resistivity at room temperature of lower than 104 Ω.cm is one major requirement. Conductive polyimide (PI) PTC with the above level of conductivity value can be achieved by a use of carbon black (CB) as conductive filler. For materials with PTC, there is a change in resistance related to temperature. In order to reduce the amount of CB used in the PTC composites, one of well-known methods is to introduce another polymer into a polymer to generate immiscible blends. When the conductive filler is dispersed in one polymer phase, …
Development Of Microfluidic Analytical Device For Detection Of Sulfur-Containing Compounds Using Raman Spectroscopy, Duangtip Lawanstiend
Development Of Microfluidic Analytical Device For Detection Of Sulfur-Containing Compounds Using Raman Spectroscopy, Duangtip Lawanstiend
Chulalongkorn University Theses and Dissertations (Chula ETD)
In this work, microfluidic systems coupled with Raman detection for analytical applications were developed using both off-chip and on-chip synthesized nanoporous Ag microstructures (np-AgMSs) as SERS substrates. Off-chip synthesized np-AgMSs were used as on-chip SERS substrates for determination of glutathione (GSH) using a reversed reporting technique. The np-AgMSs were drop casted onto the cross channel of a microfluidic device. R6G (a Raman reporter) interacted with the embedded np-AgMSs in the microchannel to form R6G-np-AgMSs which provided high SERS signal. Then, R6G in the R6G-np-AgMSs complex was replaced by GSH, causing the decrease in SERS signal which was related to the …

Chulalongkorn University Theses and Dissertations (Chula ETD)
Alginate-calcium microencapsulation of Mesona chinensis extract (MCE) was conducted in this study. Firstly, the MCE was encapsulated by using calcium chloride (3 and 5% w/v) and sodium alginate (1.5 and 1.8% w/v) to form MC microbeads (MCB). The MCB with condition of 1.5% w/v sodium alginate, 3% w/v calcium chloride and 75% w/v MCE demonstrated the highest %encapsulation efficiency and suitable spherical shape among other conditions. According to Fourier-transform infrared spectroscopy (FT-IR), there was no strong chemical interaction between alginate and MCE. After simulated digestion, the total phenolic content (TPC) and antioxidant activity measured by ferric reducing antioxidant power (FRAP) …
