Internal clock synchronization has been investigated, or employed, for quite a number of years, under the requirement of good upper bounds for the deviation, or accuracy, between a predefined master node M and slaves S1, S2, etc. It has been tacitly assumed that the accuracy range between slaves S1 and S2 was just the same as for the master/ slave. In extensive experimental studies of unicast-b...

Changes in the natural behavior, expressing adaptation to cohabitation in a community, were observed in the slave-making ants P. rufescens and the slave-species F. fusca and F. cinerea. After a few raids, the initially undirected arousal evoked in the slaves by the amazons' raids, begins to acquire attributes appropriate to the situation, but completely different in both studied slave-species. ...

Bluetooth is a personal wireless communication technology and is being applied in many scenarios. It is an emerging standard for short range, low cost, low power wireless access technology. Current existing MAC (Medium Access Control) scheduling schemes only provide best-effort service for all masterslave connections. It is very challenging to provide QoS (Quality of Service) support for differ...

In this paper, we deal with the optimal topology design in wireless personal area networks based on the Bluetooth technology. The problem consists in determining how to connect network nodes and group them into piconets in such a way that the system performance is optimized. Each piconet includes one central controller, the master, and several nodes called slaves. Since one of the major issues ...

Abstract While slavery was unconventional in Northeast Asia the eighteenth and nineteenth centuries, it has been documented Korea from Three Kingdoms period (BC 57–AD 668). In 1731, a new regulation introduced that stipulated child slave only if its mother slave, regardless of status child’s father. This led to dramatic decrease number slaves. addition, slaves also deserted more frequently afte...

Current web-based visualizations are designed for single computers and cannot make use of multiple devices, even when a user has access to not only a laptop, but also a tablet and a smartphone. We present VisHive, a JavaScript toolkit for constructing web-based visualization applications that can transparently connect multiple devices—called cells—into an ad-hoc cluster—called a hive—for local ...

For moral reasons, we should not (now or in the future) create robots to replace humans in every undesirable job. At least some of the labour we might hope to avoid will require human-equivalent intelligence. If we make machines with human-equivalent intelligence then we must start thinking about them as our moral equivalents. If they are our moral equivalents then it is prima facie wrong to ow...

Stochastic variational inference (SVI) employs stochastic optimization to scale up Bayesian computation to massive data. Since SVI is at its core a stochastic gradient-based algorithm, horizontal parallelism can be harnessed to allow larger scale inference. We propose a lock-free parallel implementation for SVI which allows distributed computations over multiple slaves in an asynchronous style....

We use slave voyage data from 18th century Great Britain and France to answer two questions: 1) How important was the managerial quality of owners and captains in slave trading? and 2) What explains the substantial variation in managerial quality? Utilizing the Trans-Atlantic Slave Trade Database, in which we observe the performance of owners and captains in each of their voyages, we follow the...
