An analysis of nonprofit board interlock networks
… each other. One such network is that of board interlocks, which occur when people serve on multiple boards of directors. In this thesis, I investigate the structures of these board interlock networks and how they relate to their local communities. I gather names of nonprofit board members from …

Comparison and results of sheet pile interlock analysis
… and used for the analysis of a single sheet pile interlock (Chan and Barker (1985), Wu and Barker (1986). In this study, the program is modified to simulate a sheet pile pull-out test with a new finite element mesh. The improved mesh contains a full-length sheet pile with both of its interlocks …

Asphalt Mixture Design Concepts to Develop Aggregate Interlock
… mixture design concepts that utilize aggregate interlock and aggregate packing to develop an aggregate blend that meets volumetric criteria and provides adequate compaction characteristics. The presented concepts rely on coarse aggregate for the skeleton of the mixture with the proper amount of …

Assessing the Effects of the Ignition-Interlock Device on Recidivism
… Safety Administration, 2013a). The ignition-interlock device is one intervention method to reduce driving while intoxicated. The present study evaluates the ignition-interlock device’s effect on DWI recidivism when used during different post-arrest phases, including pretrial, probation, and …

An experimental investigation of sheet pile interlock behavior under lateral pressure
… load transfer characteristics, and interlock response. Average effective E-ratios over three different pressure ranges were computed, interlock force versus pressure relationships were derived, the stress states in the pile webs were examined, and interlock force versus interlock …

Developing a simulator to aid in the design of a safety interlock for self-driving cars
… being easily verifiable; we call this the safety Interlock. This thesis focuses on the scenario of an ego car driving in a single, straight lane behind a lead car that may suddenly brake. We first propose and prove, using formal verification, an algorithm for Interlock to prevent collision by …

An experimental investigation of the static coefficient of friction for sheetpile interlocks
… static coefficient of friction for sheet pile interlocks was investigated in this study. The effects of cyclic displacements on the coefficient of friction of the interlocks was also examined. A broad range of values for the coefficient of friction was observed for over 2000 observations of the …

Extensometría de la organización espacial de rompefuerzas en puentes con pilar intermedio
… óseo peridentario. El uso de un rompefuerzas, interlock o conector no rígido por mesial o distal en el pilar intermedio sería la solución para anular el fulcro y disminuir el estrés. No obstante no hay evidencia científica suficiente para decidir si biomecanicamente es más favorable este diseño …

The Effects of Geography and Proximity on Board of Directors: An Exponential Random Graphs Approach
… proximity effects on the likelihood of board interlock ties creation, while controlling for endogenous network processes. Additionally, all proposed network specifications are simulated in order to assess the extent to which the small world phenomenon of the board of directors is affected by …

Analysis of slab-on-grade pavement systems subjected to wheel and temperature loadings
… and wheel loadings are considered. Aggregate interlock and dowel bars may be taken into account as load transfer devices at the joints or cracks.

Nonlinear finite element analysis of sheet pile interlocks
… developed to depict the behavior of a sheet pile interlock connection in an axial pull test. Two types of sheet piles, PS32 and PSX32, are considered. The thumb and finger in the interlock of a sheet pile will provide three contact points for connection with another sheet pile. The problem is …

Zum Schubrissverhalten von Stahlbeton- und Spannbetonbalken aus Normal- und Hochleistungsbeton
… truss model of Mörsch, exclusively to aggregate interlock forces. In this way, the concrete contribution is considered solely by a more flat strut inclination q and accordingly the whole shear capacity is described by a pure truss-model. In order to check this model, experimental and theoretical …

Bridging the gender gap: factors enabling female directors to affect the appointment of female CEOs
… the upper echelons of other firms through board interlock ties and (2) when the organization or industry has a higher-level of female-friendliness. I test this argument by analyzing 1,096 CEO succession events in large United States firms from 1998 to 2012. I found that the likelihood of …

Application of Fracture Mechanics to Assess Reflective Cracking Potential in Airfield Pavements
… I loading associated, higher degree of aggregate interlock across PCC joints did not directly contribute to the reduction of critical overlay responses. Due to the stiff underlying rigid pavement, the critical overlay responses were relatively unaffected by quality of subgrade support.

Numerical Simulation of Reinforced Concrete Subjected to Multiaxial Stress Conditions
… behavior caused by cracking, crushing, aggregate interlock, bond slip, dowel action, shrinkage and creep. Because the reinforced concrete involves so many nonlinear phenomena interacting with one another, the formulation of a "complete" analytical model is very difficult. The focus of this study …

Finite element analysis of cellular structures subjected to wave loads
… The primary objective was the assessment of the interlock force fluctuations in the sheetpiles induced by the wave action on the structure;It has been well established that the conventional design methods for cellular structures have substantial shortcomings. These methods are usually …

The Role Of Director Interlocks On A Firm's Choice Of Foreign Market Entry Mode
This study investigates the role of director interlocks and how it can have an influence on a firm’s choice of foreign market entry mode. A review of foreign market entry mode literature has indicated a lack of research from the perspective of decision makers in a firm, particularly the board of …

Chromic acid anodized Ti-6Al-4V: its characterization and its single lap bond strength to heat resistant adhesives
… and oxide/adhesive interphase mechanical interlock. Structural, durable CA/HF anodized Ti-6Al-4V-adhesive bonds were produced for all adhesives tested except for the filled polyimide (5.5 MPa). The filler may have occluded oxide pores and prevented optimal adhesive/oxide interphase …
