Exposing the seams : the impetus for reforming U.S. counterintelligence
U.S. counterintelligence is in need of reform. The September 11, 2001 attacks by Al-Qa'ida against America highlight this fact but are not in themselves the reason counterintelligence should be reformed. Not surprisingly these attacks have stirred a general debate on how U.S. intelligence ought to …

L.A. Micro-Publics : expanding the seams of the transportation system
The global city is the privileged site of "repositioning ... citizenship in practice," where traditional notions of identity and citizenship are being radically reconstructed. This thesis examines contemporary Los Angeles as such a site, a heterotopia built on difference, without a coherent civic …

Landscapes of the Hinged Trunk: With Seams of Glass and Bone
This thesis engages the construction of a particular kind of artwork, namely an artwork that functions as an occult device, capable of affecting the physical body of the viewer as well as the space the artwork occupies. The procedure described is a process of searching out and defining the formal, …

Using the Landau-Levich law to seal seams in waterproof clothing
… garment. This paper examines a method of sealing seams in which the needle waterproofs the holes it creates by sealing them with a film of a thickness governed by the Landau-Levich law. The equation governing Landau-Levich behavior is combined with equations describing hole geometry to develop a …

An Auto-Picking Algorithm For The Detection of Clay Seams In Potash Mines Using GPR Data
… of the presence and distance of clay seams from the mining zone. Clay seams are a weak point of possible failure and as such, a buffer distance needs to be maintained between the clay seam and the mining roof. In addition to safety, knowledge of the position of clay seams helps in the …

Mending the seams of an Urban Patchwork Quilt : achieving an 'Ordered Chaos' in temple towns of Southern India
Historically rich and culturally vibrant, the city of Mylapore (located in Tamil Nadu) is a prominent temple town of Southern India, in which the Kapaleeshwarar Temple is treasured. The analysis of this town, in relation to its urban context, demonstrates the need for an architectural typology that …

Characterizing the failure of parachute seams : the impact of stitch concentration and strain rate on ultimate tensile strength
… at the weakest point of the parachute, the seam. Seams are characterized by a seam efficiency, a percentage of the strength of the cloth used to stitch the seam together. In this study, seams and cloth were tested to failure on an Instron 5582 to experimentally determine their respective Ultimate …

Interaction effects due to subsidence in multiple seam mining
… coal fields contain many contiguously placed seams of coal. Mining in these seams has been active over such an extended period of time that considerable knowledge has been gained in the area of multiple seam mining. It is commonly accepted that the preferred sequence of extracting contiguous …

Carbon Dioxide Storage in Coal Seams with Enhanced Coalbed Methane Recovery: Geologic Evaluation, Capacity Assessment and Field Validation of the Central Appalachian Basin
… benefits to sequestering carbon dioxide in coal seams. This is possible because of the affinity of coal to preferentially adsorb carbon dioxide over methane. Coalbed methane is the most significant natural gas reserve in central Appalachia and currently is economically produced in many fields in …
