Adding fibers to a liquid thread increases the viscosity, hence slows early stretching of thread, but it also alters later breakup dynamics and induces considerable variability in necking shapes.

Purpose: The aims of the present study are to correlate the ISQ values, registered by the Osstell ISQ system, with the insertion torque during the placement of the implant, and to assess the influence of the thread initiator on the ISQ values and on the insertion torque. Materials and methods: 140 rough surface implants screw-shaped implants, placed in 10 bovine ribs, were assigned to Group A (...

OBJECTIVES To evaluate the initial stability of dual-thread miniscrews by analyzing the strain at the bone-implant interface and insertion torque during implantation in artificial bone models with different cortical bone thicknesses. MATERIALS AND METHODS Insertion torque, and strain, measured with a five-element strain gauge in 1.0, 1.5, and 2.0-mm artificial cortical bone, during insertion ...

introduction: multileaf collimator (mlc) is state of the art among the radiation field shaping systems for conformal radiotherapy techniques. some advantages of this system are as follow: reduction of treatment time, higher precision in conforming the radiation field to the projection of the target volume and lowering the chance of errors made by technologists. the purpose of this research was ...

Infinite-state reachability problems arising from unboundedthread program verification are of great practical importance, yet algorithmically hard. Despite the remarkable success of explicit-state exploration methods to solve such problems, there is a sense that SMT technology can be beneficial to speed up the decision making. This vision was pioneered in recent work by Esparza et al. on SMT-ba...

During the Mach In Kernel Servers work we explored two alternate thread models that could be used to support traps to in kernel servers In the migrating threads model we used the client s thread temporarily moves into the server s task for the duration of the call In the thread switching model an actual server thread is dispatched to handle client traps Based on our experience we nd that the mi...

MPI implementations that support the highest level of thread safety for user programs, MPI THREAD MULTIPLE, are becoming widely available. Users often expect that different threads can execute independently and that the MPI implementation can provide the necessary level of thread safety with only a small overhead. The MPI Standard, however, requires only that no MPI call in one thread block MPI...

Pullout failure is one of the primary failure modes of API round thread casing connections. Make-up torque and thread tolerances are the two most important factors that can affect the pullout strength. In this paper, the pull-out failure process and mechanism are studied using the finite element analysis (FEA) method. In addition, the effects of make-up torque and thread tolerances on the pullo...

Taking advantage of multi-thread technology provided by multi-core in single processor, this paper describes multi-thread implementation on fingerprint direct-access strategy using local-startopology-based discriminator features. Multi-thread was applied for data partitioning on hashing addlookup process, and for work partitioning on similarity score computation. Efficiency of the implementatio...

Data prefetching via helper threading has been extensively investigated on Simultaneous MultiThreading (SMT) or Virtual Multi-Threading (VMT) architectures. Although reportedly large cache latency can be hidden by helper threads at runtime, most techniques rely on hardware support to reduce context switch overhead between the main thread and helper thread as well as rely on static profile feedb...
