A flexible bandwidth management scheme namely Bandwidth-based Polling (BBP) for Bluetooth is proposed. A framing structure of time is defined in BBP, and the master allocates proper number of slots for each active slave in a frame. BBP allows the master to poll a slave more than once to achieve high flexibility for bandwidth allocation. The calculation of the polling time as well as the payload...

After the emancipation of African slaves in the Caribbean, the labor void left by out-migrating former slaves was filled by in-migrating indentured servants from prepartition India and China. In some areas of the Caribbean such as Trinidad, Suriname, and Guyana, the East-Indian migrants formed large communities. In this article, we report a study based on mtDNA and Y-chromosomal markers of a sm...

PvmJobs is a general bag-of-jobs library for PVM that works with any user created job structure in a master/slave paradigm. A master can spawn slave processes, schedule and dispatch jobs to slaves, coordinate and synchronize the activities. A slave process obtains a job from the master, performs a set of prescribed tasks, returns results to the master, and obtains the next job. Slaves are organ...

Clock synchronisation is a mature and important aspect of distributed computing systems. Despite the importance of accurate timing in music, there are relatively few widely applicable synchronisation solutions available to computer music practitioners. In this paper we present a simple OSC-based synchronisation method for wired and wireless applications, which is designed to be easy to apply an...

In this paper we propose a parallel approach for the Kmeans Vector Quantization (VQ) algorithm used in a twostage Hidden Markov Model (HMM)-based system for recognizing handwritten numeral strings. With this parallel algorithm, based on the master/slave paradigm, we overcome two drawbacks of the sequential version: a) the time taken to create the codebook; and b) the amount of memory necessary ...

Can part of Africa’s current underdevelopment be explained by its slave trades? To explore this question empirically, I combined data from ship records with data from various historical documents reporting slave ethnicities, and construct estimates of the number of slaves exported from each country during Africa’s slave trades between 1400 and 1900. I find a strong robust negative correlation b...

“When, on May 13, 1888, Princess Isabel signed the Golden Law there were still 723,419 slaves in our country. To reach that victory, that has maintained the name of The Redeemer [Isabel] in the hearts of Brazilians, the entire nation mobilized; the parties rose up; for many years Parliament was in a constant state of agitation; much of the press went all out for the liberation of the slaves. [N...

This research has two components, both involving the CASEsim framework. First, we must handle a few practical concerns, such as increasing the framework’s usability and implementing the ability to distribute computation. To achieve this, we use XML configuration files for usability and the Java RMI library for distributed computing. Second, we will study load balancing techniques for 0-dimensio...
