The question of the early evolution of stellar angular momentum is an interesting and essentially unsolved problem. It is well known that a substantial number of young stars show spin rates well below their break-up speed [4], despite the fact that these stars should spin up as they contract towards the main sequence. Furthermore, the angular momentum distributions of older stellar clusters suc...

in this work, time domain analysis is used to solve adler’s equation in order to obtain the required time, for an oscillator under external injection, reaching the steady-state condition. mathematical approach has been applied to fully describe the transient of frequency acquisition in injection-locked lc and ring oscillators considering their time-varying nature. then, the analysis is verified...

We discuss three forms of phantom prevention locking that have been proposed in the literature: (1) predicate locking [EGLT76], (2) precision locking [JBB81], and (3) index locking (specifically, KVL/IM locking [MOHAN90, MOHAN92, MOHAN96]). The predicate locking method was dropped from consideration in System R because of perceived problems [CHETAL81]. The precision locking technique was propos...

conclusions the use of variable-angle locking plates in treating unstable distal end radius fractures is associated with excellent to good functional outcomes with minimal complications. objectives this study aimed to evaluate the functional and radiological outcomes in unstable distal end radius fractures treated with variable-angle locking plates. patients and methods we reviewed 23 unstable ...

background: there are few studies comparing the biomechanical properties of angled blade plate and locking compression plates in supracondylar osteotomy. in the current randomized study, we prospectively compared the clinical and radiological outcomes of supracondylar osteotomy using these two plates. methods: forty patients with valgus knee malalignment were randomly assigned to two equal numb...

A finite element method is considered for dealing with nearly incompressible material. In the case of large deformations the nonlinear character of the volumetric contribution has to be taken into account. The proposed mixed method avoids volumetric locking also in this case and is robust for λ→∞ (with λ being the well-known Lamé constant). Error estimates for the L∞-norm are crucial in the con...

This paper analyses the interaction techniques, which are required to build and execute a material flow simulation model. Based on these techniques potential conflicts, aroused by parallel action of different users on one model, will be analysed. A locking, versioning and cloning based method set will be introduced and discussed to solve these problems. Finally the architecture, on which these ...

Example Commercial Web servers typically maintain a ‘hit count’ component that records how many times each URL is accessed by clients over a period of time. To reduce latency, a Web server process does not maintain the hit counts in a file on disk but rather in a memoryresident table. Moreover, to increase throughput, Web server processes are often multi-threaded [HS98]. Therefore, public metho...

We present multiversion timestamp locking (MVTL), a new genre of multiversion concurrency control algorithms for serializable transactions. The key idea behind MVTL is simple and novel: lock individual time points instead of locking objects or versions. After showing what a generic MVTL algorithm looks like, we demonstrate MVTL’s expressiveness: we present several simple MVTL algorithms that ad...

Injection locking characteristics of oscillators are reviewed both theoretically and experimentally. Theoretical results coupled with experimental findings are presented. A simple method of deriving the equation for locking range is reported.
