Most multiprocessors are multiprogrammed in order to achieve acceptable response time and to increase utilization. Unfortunately, inopportune preemption may significantly degrade the performance of synchronized parallel applications. To address this problem, researchers have developed two principal strategies for concurrent, atomic update of shared data structures: preemption-safe locking and n...

In the recent functional linguistic literature, the notion of syntactic complexity and similar concepts have received considerable attention. Yet, when trying to operationalize syntactic complexity as an independent variable in statistical research designs, it soon emerges that the notion is somewhat underdefined. I will report the results from an experiment comparing three measures of syntacti...

We use experimental methods to investigate whether pledges of commitment can improve cooperation in endogenously-formed partnerships facing a social dilemma. Treatments vary in terms of the individual’s: (1) opportunity to commit to their partner; (2) the cost of dissolving committed partnerships; and (3) the distribution of these dissolution costs between partners. Our findings show that pledg...

This paper introduces a new approach to the control of robot manipulators in a way that is safe for humans in the robot's workspace. Conceptually the robot is viewed as a tool with limited autonomy. The limited perception capabilities of automatic systems prohibits the construction of failsafe robots with the capabilities of people. Instead, the goal of our control scheme is to make the interac...

Ultrasonography is a relatively easy, safe and non-invasive examination method which can be used in diagnosis of ocular disorders as complementary to routine ophthalmic examinations. As there has been no collated study undertaken on the normal measurements of ocular structures in Caspian miniature horse, obtaining these measurements could be a benchmark to diagnose some of the diseases and eye ...

Transmission of blast waves is a complex phenomenon and the characteristics vary with blast design parameters and geo-technical properties of medium. Frequency of vibration and triggering component for structural excitation generally quantifies safe vibration magnitude. At closer distance or higher elevations than the blast locations, vertical or transverse component will be the first arrival t...
