Buch. Zustand: Neu. Neuware - Did You Hear That Help for Children Who Hear Voices is a fully illustrated 85-page children's book about Susie and 4 other children. Susie is a 9 year old who keeps her challenges with auditory and visual hallucinations a secret until a school teacher alerts her parents of her less than optimal functioning at school. With compassion, empathy, love and understanding, Susie's parents encourage her toward seeing a counsellor. Susie builds trust and rapport with her counsellor that finally allows her to share her well-guarded secret. After divulging what had been ailing her for years, with the counselor's help she discovers that she is not the only one on earth that struggles with voices. She proceeds to introduce 4 other children of different ethnicities, ages, backgrounds, talents and interests who have similar struggles with voices. Finally all the children share with readers their personal choices regarding what role they wanted voices to have in their lives (i.e. to keep the voice by managing it, get rid of voice) and how counsellors helped them achieve their individual goals.A beautifully illustrated practical tool for psychologists, psychiatrists and mental health practitioners treating children with auditory and visual hallucinations. Being a user-friendly guide for concerned parents, teachers, paediatricians and allied professionals, it is easy to understand, normalises the experience and assists children in seeking professional help.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Scientific Study from the year 2016 in the subject Engineering - Communication Technology, Mahalingam College of Engineering and Technology, language: English, abstract: The future Wireless Communication Systems (WCS) are supposed to provide high data rate to support personal and multimedia communications irrespective of the users' mobility and location. These services include heterogeneous classes of traffics such as voice, file transfer, web browsing, wireless multimedia, teleconferencing, and interactive games. In recent years, data and multimedia services have become important in wireless communications. As a result, bandwidth requirement and number of users become delicate problems. To support high data rate requirement for future WCS, it is essential to efficiently allocate the limited resources. The major challenges are the dynamic nature of wireless channel, limited resources such as power,frequency spectrum, and diversified Quality of Service (QoS) requirements. Orthogonal Frequency Division Multiplexing (OFDM) is a special case of multicarrier transmission that supports high data rate operation. OFDM is a modulation and multiplexing technique appropriate for current and future wireless networks. OFDM divides the available bandwidth into a number of parallel independent orthogonal subchannels and their bandwidth is much less than the coherence bandwidth of the channel. The wide band frequency selective fading channel is converted into several narrow band flat fading channels. OFDM is an excellent method to overcome multipath fading effects. One of the goals of WCS is to enhance the capacity of the channel. Multiple Access Technique (MAT) permits several mobile users to share the given bandwidth in an effective way. Basically there are four multiple access techniques available namely, Time Division Multiple Access (TDMA), Frequency Division Multiple access (FDMA), Code Division Multiple Access (CDMA) and Space Division Multiple Access (SDMA). MAT is employed in terms of fixed time slots, fixed subchannels, and unique codes in TDMA, FDMA and CDMA respectively. SDMA makes use of the spatial separation of the users to optimize the bandwidth. MAT can be combined with OFDM in terms of frequency, time or code separation between the users. The difficult task is to assign the scarce radio resources like subchannels, time slots, bits and power to multiple users.
