Architecture, as the art of making a building, consists of an assemblage of elements that interact and interlock to create something whole—from an assembly of parts, emerges a unified composition. In this thesis exploration, I strive to take this simple idea, fundamental to all buildings—to the very process of building itself—and utilize it as a driving force. This proposal was conceived both as a response to the site and program,as well as an effort to control an arrangement of parts in order to create an integrated, functioning whole that is greater than the sum of its parts. The resulting architecture derives its existence and identity from the articulation of these individual elements and the manner in which they interact and connect. Furthermore, this choreography generates a certain sequence of spaces creating moments of pause, compression, and release. There is a certain level of complexity that results from the formal play of setting elements into motion against the site and each other. Accepting this condition, the designer's will must be exerted in an effort to gain/maintain control of this composition. As such, this architecture explores the possibilities of complexity generated through the formal arrangement of parts. / Master of Architecture

Interlocking Concrete Pavements (ICP) have been successfully used in many pavement applications all across the world. ICP design and analysis methods, construction practices and materials specifications have been developed. However, there is very limited field data to quantify structural performance with respect to traffic and environmental loadings. The interaction between traffic loadings and environmental factors needs to be explored in order to improve relationships between pavement performance and response. Pavement performance prediction in terms of fatigue cracking and surface rutting are essential for any mechanistically-based pavement design method. The estimation of the expected fatigue performance in the field is based on the quantification of the maximum tensile strain in bound base layers and the expected rutting performance is based on maximum vertical stress/strain in granular layers. This thesis presents an innovative research project involving the design, construction, instrumentation, performance modeling and distress evaluation of seven ICP crosswalks with four different design assemblies. The research projects were constructed at the Centre for Pavement and Transportation Technology (CPATT) test track and at the University of Waterloo ring road. Each of the test sections is instrumented with structural and environmental sensors of sensors to monitor the pavement performance under heavy truck traffic, typical municipal loadings and to quantify environmental effects. A database is generated and the measured stress, strain, temperature and moisture measurements are analysed to evaluate the expected long-term performance of the structural components of ICP crosswalk designs.

Interlocking Concrete Pavements also known as block pavements are one of the integral parts of the pavement system in Europe. The use of ICP slowly extended to other countries including North America. As the usage increased the need for more scientific research was developed which resulted in the study of ICP design and analysis methods, construction practices and materials specifications. This thesis presents a research project involving the design, construction, instrumentation, performance modeling and other field tests of eight ICP crosswalks with four different design assemblies. The research projects were constructed at the Centre for Pavement and Transportation Technology (CPATT) Test Track and at the University of Waterloo Ring Road.

The current investigation examined the effectiveness of a metacontingency package in two experimentations. In experiment one, the metacontingency was utilized by embedding activities with interlocking behavioral contingencies to examine its effectiveness on reciprocal social interactions in two females diagnosed with an Intellectual Disability. Results demonstrated an increase of the dependent variable by the metacontingency activities. The results of experiment one were the premise for experiment two, which was to examine whether the metacontingency activities that were effective in increasing reciprocal social interactions were an effect of the metacontingency or an effect of engaging in an activity together. Experiment two utilized two activity types, parallel and metacontingency activities, to determine their relative effect on self-talk behavior, reciprocal social interactions, and conversational units in two males diagnosed with an Intellectual Disability. Results suggested that there were no relative effects demonstrated by the two activity types on self-talk behavior, however results demonstrated an increased effect by the metacontingency activities relative to the parallel activities on reciprocal social interactions and conversational units.

Each year, thousands of femoral and tibial internal fracture repairs are performed by orthopedic surgeons in the United States. Internal fixation of long bones using intramedullary nails (IMN) has decreased incidence of non-union, allowed shorter hospitalization time, and earlier weight bearing for the patient compared to other fixation methods. Orthopedic surgeons have expressed that one of the most difficult parts of this intramedullary nailing of long bones, is locating and drilling the interlocking screw holes. IMN interlocking requires the surgeon to locate the holes in the nail, center the drill, and advance the bit through the bone to meet them. Many novel procedures and devices have been developed to assist the surgeon in distal locking of intramedullary nails, but have some disadvantages. These can include the need for extensive x-ray exposure, expensive x-ray equipment, high power consumption, active electronics in vivo, soft tissue damage, which all lead to inaccurate screw placement. For these reasons, a new prototype device for locating and drilling IMN distal interlocking holes has been developed. This prototype device uses magnetic sensors to locate a permanent magnet placed at a know distance from the IMN interlocking hole. A drill sleeve may be attached to the targeting sensors so that when they are aligned with the target magnet, the drill sleeve is aligned with the axis of the interlocking hole to be drilled. This new prototype device has significant advantages over existing devices, including the following. It has no active or passive electronics in vivo, no x-ray imaging is needed for targeting, while allowing real time feedback of alignment. It is a percutaneous technique, which can be adapted for use with existing IMN's. The new prototype also has low power requirements allowing battery operation, a single target magnet with unique axisymmetric field and novel magnet orientation, and adjustable sensitivity. Additionally, the new device allows visual, audible, or tactile positioning feedback. This prototype magnetic targeting device can improve orthopedic surgeons' ability to target and drill distal IMN interlocking screw holes. This device may allow shorter surgery, decreased x-ray exposure, and fewer complications for the surgeon and patient. / Master of Science

No / This paper explores the character, density and likely importance of connections between directors of a sample of 12 early-twentieth century British multinational companies. Drawing on the notion of `gentlemanly capitalism¿, a reconstruction of multiple and interlocking directorships for 1899¿1900 and 1929¿1930 indicates that a complex network existed that comprised links, respectively, to 255 and 497 companies. We explore the social, cultural and political characteristics of the directors of our sample and argue that the ways in which members of this group interacted with each other would have influenced business attitudes, facilitated transfers of knowledge and promoted interdependencies, thereby shaping commercial behaviour. We argue that the directors of early multinationals formed the kind of definable `power geometries¿ within the wider corporate elite that have been identified amongst today's business elites. Our results indicate that a distinct and increasingly dynamic multinational corporate community existed in the early 1900s, which was in many respects like its modern counterparts. A key finding is that the complexity of dyadic connections between directors and their personal networks of contacts increased markedly between 1899¿1900 and 1929¿1930.
