The paper presents an EEG-based wireless brain-computer interface (BCI) with which subjects can mindspell text on a computer screen. The application is based on detecting steady-state visual evoked potentials (SSVEP) in EEG signals recorded on the scalp of the subject. The performance of the BCI is compared for two different classification paradigms: synchronous and asynchronous modes.

This paper studies the design of data fusion algorithm for asynchronous system with integer times sampling. Firstly, the multisensor asynchronous samplings is mapped to the basic axis, accordingly a sampling sequence of single sensor can be taken. Secondly, aiming at the sensor with the densest sampling points, the modified parallel filtering is given. Afterwards, the sequential filtering fusio...

Modern distributed applications rely upon the functionality of services from multiple providers. Mission-critical services, possibly shared by multiple applications, must be replicated to guarantee correct execution and availability in spite of arbitrary (Byzantine) faults. Furthermore, shared services must enforce strict fault isolation policies to prevent cascading failures across organizatio...

The increasing complexity of modern VLSI systems has caused designers to reevaluate the ageold decision of using a single, central clock and instead turn to asynchronous or globally asynchronous, locally synchronous (GALS) designs. Communication between synchronous and asynchronous subsystems is difficult to do reliably and efficiently. In this paper, we review the background for the difficulty...

Research has consistently shown that males play violent video games more frequently than females, but factors underlying this gender gap have not been examined to date. The present approach examines the assumption that males play violent video games more, because they anticipate more enjoyment and less guilt from engaging in virtual violence than females. This may be because males are less empa...

This paper describes research work on collaborative process modeling and model-based computer support. It shows how collective issue resolutions can be modeled in the context of collaborative processes, and how other collaboration structures, such as negotiation and negotiated contracts, derive from that primitive structure. These ideas are illustrated through CPCE, which is a generic process-c...

Within the field of second language acquisition, pronunciation has received relatively little attention. This lack research can also be seen in general systematic pedagogical materials for training, effectively reinforcing “marginalized” nature classroom (Lee, Plonsky & Saito, 2019). Accordingly, current study investigated use synchronous/asynchronous computer-mediated communication as a method...

The Equal Employment Opportunity Commission (EEOC) has experienced dramatic backlogs of pending charges over the years. In 1977, the backlog reached an all-time high of 130,000 cases pending. Recently, the EEOC announced that the backlog had been reduced to 29,890 cases. A significant portion of this reduction is attributab le to an increased use of mediation. During FY 2001, 7,800 of the 94,59...
