the purpose of this study is to explore and classify the perceptions of the phenomenon of hypocrisy in organization from viewpoint of employees in a university using phenomenography, so that achieving to a deeper understanding of this phenomenon. sampling was done by maximum variation method and sample size was determined 30 people using theoretical saturation. some open semi-structural intervi...

In many streaming speech recognition applications such as voice search it is important to determine quickly and accurately when the user has finished speaking their query. A conventional approach to this task is to declare end-of-query whenever a fixed interval of silence is detected by a voice activity detector (VAD) trained to classify each frame as speech or silence. However silence detectio...

With fast deployment of wireless local area networks (WLANs), the ability of WLAN to support real time services with stringent quality of service (QoS) requirements is attracting ever-increasing research interest. In this paper, we evaluate the capability of the point coordination function (PCF), which is part of the medium access control (MAC) mechanisms specified in the IEEE 802.11 standard f...

Many researchers have seen in the articulation an intermediate level of representation. In the gestural phonetic theory, units are articulatory gestures. In order to assess this theory with observed parameters, we have defined a robust labelling system (AMULET) of the multi sensor ACCOR speech database. Main articulatory gestures searched are Voice Onset and Voice Termination on both acoustic a...

This paper presents a new dynamically adaptable polling scheme for efficient support of voice communications over different IEEE802.11 networks. The proposed polling scheme is simple to implement and does not require any modification on the existing access protocol. The analytical approach that models the proposed polling scheme, uses a discrete-time Markov chain and proves that the specific po...

Silence infuses all aspects of our daily communications: what we say and remains unspoken; those to whom speak, ignore; trust respect, do not. In the school environment, interactions between students teachers lie at heart pedagogy. This relationship is also marked by its silences, concept ‘student voice’ arose out these silences on matters that affect students. However, role silence in such has...
