The movement of a hair collective is a highly complex phenomenon with major contributions of hair-hair interactions, shape and alignment of the hair collective. All these influences are assessed and taken into account for further studies. The main objective is to investigate the relationship between the structural int…
[[abstract]]本文首先對非織造材料進行同視野多個據焦平面連續圖像採集；再將這些圖像融合成一幅清晰的圖像，之後利用邊緣檢測運算元提取纖維邊界；最後計算纖維段切線角度積分，從而快速準確地計算非織造材料纖維取向。由人工對電鏡圖片進行測試驗證及短隔距力學拉伸實驗進行結果驗證表明本文提到的新方法可以精確迅速地測量非織造材料的纖維取向情況。 The application of image fusion technology in nonwoven was discussed. Firstly, the nonwoven's images that in the same vision and different focal pla…
As part of the MUZIC-2 project, several state-of-the-art high resolution analysis techniques are being used to study the microstructure of a range of commercial and developmental Zr alloys corroded under autoclave simulated PWR conditions. Samples were chosen to be representative of the early, pre-transition, transiti…
[[abstract]]本研究之目的為探討腿部穿著壓力褲對於跑步時的運動表現和舒適性之影響。受試者招募為平時有有氧運動習慣之男性；4位受測者年齡在22~27歲之間，VO_2Max平均為45±4(ml．kg^(-1)．Min^(-1))。受試者穿著無壓力褲(CO)和高壓力褲(CT)以最大攝氧量(VO_2Max)測試並篩選受測者。再以目標攝氧量60%進行40分鐘跑步實驗。使用運動心肺系統，採用每次呼吸測量法(一口氣法)，對呼吸過程中氣體的流量、O_2濃度、CO_2濃度、心臟參數等參數進行資料的蒐集。本研究以代謝當量(METs)表示運動的能力。跑步過程中評估服裝體感溫濕度與舒適性。實驗結果穿著高壓力的壓力褲在中運動強度(60% VO_2…
[[abstract]]本研究系利用海藻酸鈉膠體、十二烷基硫酸鈉水溶液與回收紙纖維混合，經充分的均勻攪拌後微波發泡固形，配製出不同比例的無土栽培樣本。探討相同濃度的海藻酸鈉膠體克重、相同的微波發泡時間，和相同濃度的十二烷基硫酸鈉水溶液但不同克重，以及紙纖維不同克重，對樣本的發泡成形性及物性的影響。本研究將探討利用回收紙纖維當作栽培介質主體，並添加海藻酸鈉膠體和十二烷基硫酸鈉水溶液，混合後發泡後再泡氯化鈣水溶液固化進行交聯(cross linking)。 This study takes advantage of alginate gel, sodium lauryl sulfate solution is mixed with r…
[[abstract]]黏土是由含鋁的矽酸鹽類礦物所組成，其大小小於2μm，由於雪山山脈帶和脊樑山脈帶的岩層岩性以板岩和硬頁岩為主，含少量變質砂岩，所以無法從顯微鏡中判斷這些地區礦物相的差異性，故本研究希望能利用岩石中的黏土礦物相了解雪山山脈帶和脊樑山脈帶的岩層特徵。本研究以X光繞射分析這些岩層中黏土礦物種類，並計算這些黏土礦物相之含量百分比。本研究結果顯示，脊樑山脈的伊萊石結晶度以淺變質帶～成岩帶為主；雪山山脈的伊萊石結晶度以近變質帶～成岩帶為主。而環山地區的黏土礦物相為伊萊石、高嶺石、綠泥石；高嶺石主要出現於環山地區的西南方，其含量百分比多數為10～20%；環山地區東南方之綠泥石礦物較為富集，其含量百分比多數為20～30%；伊…
Cette thèse est consacrée à la caractérisation pétrologique et géochimique des basaltes quaternaires post-collisionnels d’Anatolie centrale (strato-volcans Erciyes et Hasandağ et volcanisme dispersé d'Obruk-Zengen et de Karapınar), en se focalisant sur l’évolution spatio-temporelle de ce magmatisme de la Cappadoce (Tu…
ABSTRACT PowerPoint Presentation Only Red phosphorous flame retardants caused millions of dollars of product failures in semiconductors in the 2000s. Recently there have been widespread failures and recalls caused by the return of red phosphorous based flame retardants but now in line cords and board connectors.
ABSTRACT Electrically conductive adhesives (ECAs) offer many advantages such as lower processing temperature, simpler processing steps and finer-pitch interconnection in comparison with the traditional soldering technology. However, due to the poor metallurgical connections of silver flakes in the ECA network, it requ…
This article discusses the dominant approaches to the map as a metaphor, practice and concept in the interdisciplinary area of contemporary theories. The focus is on relationship between map and territory. In the first part the author describes three possibilities: the map as the experiment with territory, the map as…
We present a principled technique for estimating the effect of covariates on malaria parasite clearance rates in the presence of “lag” and “tail” phases through the use of a Bayesian hierarchical linear model. The hierarchical approach enables us to appropriately incorporate the uncertainty in both estimating clearanc…

ABSTRACT Copper aluminum interconnects are being used in automotive applications for deployment underhood, onengine and on-transmission. Electronics is widely used for enabling safety function including lane departure warning systems, collision avoidance systems, antilock braking systems, and vehicle stability systems…
ABSTRACT Surface insulation resistance (SIR) and electrochemical migration (ECM) are two of the primary reliability drivers in consideration of the performance of electronic assemblies. In recent years, the concern of “partially-activated” flux residue and their influence on reliability have been significantly raised…
ABSTRACT As consumers become more reliant on their handheld electronic devices and take them into new environments, devices are increasingly exposed to situations that can cause failure. In response, the electronics industry is making these devices more resistant to environmental exposures. Printed circuit board assem…
ABSTRACT PCB (printed circuit board) surface finishes provide several important functions, the most important being solderability protection. The ideal PCB surface finish does not exist today. Every surface finish has some concerns that keep it from being the ideal finish. Surface finish selection has become more chal…
ABSTRACT Electronic components and assemblies, e.g. for power electronics, are able to generate a lot of power loss and heat as well. Especially temperature peaks and extreme temperature changes are the cause for stress, which has a negative effect on the reliability and achievable lifetime. For such demands, it is ne…
ABSTRACT This study focuses on identifying the residues found on the surface of high temperature co-fired ceramic packages after prolonged exposure to moisture. Using a “farming method”, enough residue was created to facilitate a thorough analysis. Tests using SEM-EDS, Fourier Transform Infrared Spectroscopy, Raman Sp…
ABSTRACT The iNEMI technical subcommittee on creep corrosion has developed a flowers-of-sulfur (FOS) based qualification test for creep corrosion on printed-circuit boards (PCBs). In phase 1 of the project, the performances of FOS chambers of two designs were evaluated by measuring the corrosion rates of copper and si…
ABSTRACT One of the biggest challenges facing the electronics industry today is voiding in the solder joints that connect bottom terminated components to PCBs. This solder voiding, especially on thermal pads, can lead to hot spots and a reduction in the life of the component and the overall assembly. Limited improveme…
