Gyroscopes have been used in previous studies to measure the peak angular velocity of the shoe or foot in the frontal plane (evVel). However, it is not clear whether different test conditions (footwear hardness or locomotion speed) can influence the accuracy of evVel. The purpose of the present study was to compare the accuracy of gyroscopes and electrogoniometers when measuring evVel and the time until evVel (t_evVel) in 12 different conditions using a single axis gyroscope attached to the heel cap. Twenty-four recreational runners were instructed to walk and run on a 15-m indoor track at four locomotion speeds (1.5, 2.5, and 3.5 m/s, and individual running speed) and in three footwear conditions (low to high hardness). The gyroscope data and electrogoniometer data were sampled at a rate of 1000 Hz. Comparisons between both measurement devices showed small mean differences up to 49.8 ± 46.9 deg/s for evVel and up to 5.3 ± 3.5 ms for t_evVel. Furthermore, strong relationships between gyroscope and electrogoniometer data were found for evVel as well as for t_evVel for all conditions. It can be concluded that gyroscopes can be used to accurately determine evVel and t_evVel under a variety of conditions.

Accelerometers and gyroscopes are used to detect foot strike (FS), i.e., the moment when the foot first touches the ground. However, it is unclear whether different conditions (footwear hardness or foot strike pattern) influence the accuracy and precision of different FS detection methods when using such micro-electromechanical sensors (MEMS). This study compared the accuracy of four published MEMS-based FS detection methods with each other and the gold standard (force plate) to establish the most accurate method with regard to different foot strike patterns and footwear conditions. Twenty-three recreational runners (12 rearfoot and 11 forefoot strikers) ran on a 15-m indoor track at their individual running speed in three footwear conditions (low to high hardness). MEMS and a force plate were sampled at a rate of 3750 Hz. Individual accuracy and precision of FS detection methods were found which were dependent on running styles and footwear conditions. Most of the methods were characterized by a delay which generally increased from rearfoot to forefoot strike pattern and from high to low midsole hardness. It can be concluded that only one of the four methods can accurately determine FS in a variety of conditions.

Indiana University-Purdue University Indianapolis (IUPUI) / In the last few decades, forensic science has played a significant role in bringing criminals to justice. Shoe and tire track impressions found at the crime scene are important pieces of evidence since the marks and cracks on them can be uniquely tied to a person or vehicle respectively. We have designed a device that can generate a highly accurate 3-Dimensional (3D) map of an impression without disturbing the evidence. The device uses lasers to detect the changes in depth and hence it is crucial to accurately detect the position of the laser. Typically, the forensic applications require very high resolution images in order to be useful in prosecutions of criminals. Limitations of the hardware technology have led to the use of signal and image processing methods to achieve high resolution images. Super Resolution is the process of generating higher resolution images from multiple low resolution images using knowledge about the motion and the properties of the imaging geometry. This thesis presents methods for developing some of the image processing components of the 3D impression scanning device. In particular, the thesis describes the following two components: (i) methods to detect the laser stripes projected onto the impression surface in order to calculate the deformations of the laser stripes due to 3D surface shape being scanned, and (ii) methods to improve the resolution of the digitized color image of the impression by utilizing multiple overlapping low resolution images captured during the scanning process and super resolution techniques.

NilsonGroup presenterade uppdraget att undersöka vattenbaserade lim som alternativ till lösningsbaserade lim vid tillverkning av skor, vilket var grunden till det här arbetets ämne och avgränsningar har tagits fram. Vattenbaserade lim är ett alternativ till lösningsbaserade lim som inte är lika hälsofarligt, då lösningsmedelkan orsaka allvarliga hälsoeffekter. Enligt NilsonGroup ligger skobranschen steget efter vad det gäller hållbarhet och i nuläget saknas det en satsning på hållbarutveckling, medan andra branscher är bättre på att leta efter nya möjligheter. Det här arbetet vill lyfta fram på vilka sätt vattenbaserade lim är ett mindre riskfylltalternativ till lösningsbaserade lim och visa att skillnaderna i limfogens egenskaper inte blir så olika. Första delen av resultatet innefattar en definition av lim och limning. Fokus ligger på att reda ut vad som krävs och hur en limfog skapas med ett lim mellan två ytor, för att läsaren ska få en grundlig kunskap om det innan arbetet går in på lim i skor. Det presenteras även vilka egenskaper som är viktiga för en limfog och vilka faktorer det är som vanligtvis vägs in vid val av lim. Andra delen handlar om material, lim och limfogar i skoindustrin. Resultatet visar att det är den övre delen av skon och sulan som är den mest kritiska limfogen att skapa vid tillverkningen av en sko, samt att de mest förekommande lim som används vid skotillverkning är av polymererna polyuretan och polykloropren. De material till den övre delen av skon som främst används av NilsonGroup och generellt hela skoindustrin, är syntetiskt skinn, läder och bomull. Till en skos sula används gummi och polyuretan i störst utsträckning. Resultatet kommer fram till fem olika kombinationer av material och vattenbaserade lim som har bra potential att kunna bilda en hållbar limfog. Resultatet visar även att de egenskaper som vattenbaserade och lösningsbaserade polykloropren- och polyuretanlim ger en limfog är lika, så när det kommer till att välja mellan vattenbaserade lim och lösningsbaserade lim, så är det komponenterna i limmen och riskerna de medför som innefattar den stora skillnaden. I bilaga 1presenteras alla de mest förekommande komponenter som polyuretan- och polykloroprenlim består av, samt vilka hälsoeffekter de kan orsaka vid exponering för ämnet. / NilsonGroup presented the assignment to investigate water-borne adhesives as an alternative to solvent-borne adhesives in shoe production. This represent the purpose of this work and the limitations that have been developed. Water-borne adhesives do not pose as serious health risks as solvent-borne adhesives, mainly because of the solvent that may cause serious health risks. According to NilsonGroup, the shoe industry is a step behind in terms of sustainability and there is no investment in sustainable development. While other industries are stepping forward in terms of sustainability. The purpose of this work is to highlight waterborne adhesives as a less critical alternative to solvent-borne adhesives. And to prove that the characteristics between the two choices are not so different. The first part of this work explains adhesives and adhesive bonding. The part explains the requirements and how an adhesive joint is created from an adhesive between two different surfaces. This is necessary to get the reader to understand the basics about adhesive bonding before the work focus on adhesives in shoes. Important properties related to the adhesive joint and the common factors when choosing adhesives is also a part of this work. Second part of this work deals with material, adhesives and adhesive joints in the shoe industry. The upper part of the shoe and sole bonding process is the most critical joint in the shoe and the most common adhesives in the shoe industry is made of polyurethane and polychloroprene polymers. Some common materials used in the upper part of shoes made by NilsonGroup, and the shoe industry overall, are synthetic leather, leather and cotton. The sole is usually made of rubber or polyurethane. The result presents five different combinations of material and waterborne adhesives that may have the potential to produce a durable joint. The result shows that the properties related to waterborne and solvent-borne adhesives are equivalent. When choosing type of adhesive, the components in the adhesives and the health risk they cause, makes up the big difference. Appendix 1 presents common components in polyurethane and polychloroprene adhesives along with health risks that they may cause when exposed.

Indiana University-Purdue University Indianapolis (IUPUI) / In crime scene investigations it is necessary to capture images of impression evidence such as tire track or shoe impressions. Currently, such evidence is captured by taking two-dimensional (2D) color photographs or making a physical cast of the impression in order to capture the three-dimensional (3D) structure of the information. This project aims to build a digitizing device that scans the impression evidence and generates (i) a high resolution three-dimensional (3D) surface image, and (ii) a co-registered two-dimensional (2D) color image. The method is based on active structured lighting methods in order to extract 3D shape information of a surface. A prototype device was built that uses an assembly of two line laser lights and a high-definition video camera that is moved at a precisely controlled and constant speed along a mechanical actuator rail in order to scan the evidence. A prototype software was also developed which implements the image processing, calibration, and surface depth calculations. The methods developed in this project for extracting the digitized 3D surface shape and 2D color images include (i) a self-contained calibration method that eliminates the need for pre-calibration of the device; (ii) the use of two colored line laser lights projected from two different angles to eliminate problems due to occlusions; and (iii) the extraction of high resolution color image of the impression evidence with minimal distortion.The system results in sub-millimeter accuracy in the depth image and a high resolution color image that is registered with the depth image. The system is particularly suitable for high quality images of long tire track impressions without the need for stitching multiple images.

歐盟廣泛地與世界各國簽訂優惠貿易協定，透過優惠貿易待遇的給予來促進與各國間政治與經貿的緊密連繫。而對於生產者而言，要適用這些貿易優惠的前提就是透過遵循歐盟優惠性原產地規則而使產品取得原產產品身分，無論是以完全取得或是經過充分作業或加工而產生實質轉型的方式。 本論文主要的研究目的，在於分析個別歐盟優惠貿易協定下關於累積規定、微量條款、出口退稅禁止等關鍵條文，與附錄清單就產品「實質轉型」標準規定的法律義涵，以及其隱含的政經意義；並就該意義進一步推衍出對於台灣的生產者，在眾多的歐盟優惠性協定法律架構下，存在個別規則適用難易程度具有差別且該差別將對生產成本有所影響之事實。而本論文另一重點則是就法規與生產稟賦搭配後得推衍出原則性之評估方法來評比出個別優惠性原產地規則在適用上之優劣順序，以協助台灣廠商未來考慮使用此項貿易優惠來進軍歐盟市場時，在國際投資之佈局上可以納入考量或作為參考，以選擇出最有利的受惠國或區域作為生產資源配置之基礎。 為使法律層面與實務上之運作加以結合，本論文進一步以台灣的成鞋廠商做為研究觀察之對象，檢視其是否會因為適用歐盟優惠性原產地規則而改變投資模式，另亦將與鞋廠商實際訪談所得之結論與推演出原則性評估方法加以比較，進一步檢討該評估方法之適用能力與情形，並提出應隨不同情況而加以修正相關假設之注意。 關鍵詞：歐盟優惠性原產地規則；原產地規則；原產產品；實質轉型；累積規定；微量條款；出口退稅禁止；附錄清單；生產稟賦；國際投資；成鞋。 / Europe Union (EU) broadly sign the preferential trade agreements with the other countries in the globe, and through the conferring of the preferential trade treatments, EU attempts to build up the tight political and economic bonds worldwide. The premise for producers who want to enjoy these trade preferences is to make sure that their product are qualified and recognized as “original product” in those beneficiary countries either by following the regulation of standard of “wholly obtained” or “sufficiently working or processing” stipulated in each preferential Rule of Origin (ROO). The main subject of this thesis is to analyze the legal meaning and the underlined policy purpose of the critical provisions in each EU preferential ROO, such as “cumulation”, “general tolerance rule”, “no-drawback rule”, and the standard of “sufficiently working or processing” of a product (substantial transformation) stipulated in the List Rules (in the Annex part) attached in each preferential trade agreement. And from those meaning Author reasons out the fact that the level of difficulty concerning applying and using these preferential ROO are different and the difference has its influence on cost of producing. Author also infers the basic method to assess the level of difficulty of these ROO while combining analyzing the ROO provisions and endowment in the beneficiary countries. This method is to assist those Taiwanese producers who have willing to use the EU preferential ROO to make their product qualified as “original product” with the minimized producing cost when entering into EU market, that is, to help producers cherry pick the beneficial countries (or area) for making investments distribution and deploying concerned producing resources and still have their the products entitled as “original product”. To combine the legal dimension and the producer’s operation in practice, Author further chooses Taiwanese footwear producers as observed subject of using the ROO and see if they would change their mode of investment thereafter. Author compares the conclusion derived from interviewing footwear producers with the basic assessment method, and further examines the applicability of the method and the potential correction of hypothesis under certained situations. Key words: EU preferential Rule of Origin, Rule of Origin, original product, substantial transformation, cumulation, general tolerance rule, no-drawback rule, List Rules, endowment, international investment, footwear.
