Abstract:

BackgroundTelecommunications plays a critical enabling role in disaster response, both for the local population and for responses of external origin. However, it is common for telecommunications capacity to be reduced or disabled by the disaster or emergency. Meanwhile, the disaster stimulates demand for any remaining capacity, often resulting in total loss of telecommunications capability during the acute phase of a disaster and its response.Discussion and ObservationsThe Serval Project is addressing this through the implementation of a mesh mobile telephony system that is compatible with som

Abstract:

Along with the development of the era, analog telephones have been replaced by IP Phones whose communication range can be wider and more flexible. Therefore, analog telephones are almost forgotten because of the limited communication range. With the addition of ITG (Internet Telephony Gateway) then analog telephones can communicate in VoIP networks. This research will discuss the analysis of voice quality in the communication process between telephone sets via ITG in a VoIP network based on the shape of the input and output, the amplitude response to frequency changes and the delay.

Within a mere hundred years from the appearance of the first telephone in Zagreb in 1881 until the establishment of the first electronic telephone exchange in 1981, telephony in Zagreb went through several formative periods to assert itself. Zagreb was transformed from a provincial town in the Austrian-Hungarian Monarchy to the economic and cultural centre of Croatia. In that period, due to technological development, many changes took place that influenced the accessibility and price of the most popular telecommunications technology in the 20th century.

However, ITG already has an FXS port so it does not require additional modules. In Indonesia, there are standard provisions for the use of analog telephone communication dev

This is done in two case studies. The first case study takes its starting point in Stockholm in the 1870's, a time when people in order to communicate as a rule had to meet in person. The introduction of the telephone changed this basis for human networks and social interaction in the 1880's by making it possible to engage in conversations even with persons in places out of earshot.

Abstract:

From the 1881 incorporation of Los Angeles' first telephone company, telecommunications spread rapidly in the city and its surrounding region. This article details the proliferation of telephony, and its role in the region's rapid growth and in the formation of region-wide economic networks. Conversely, Pomona, 30 miles from Los Angeles, serves as an example of how local telephone systems could also facilitate sub-regional economic blocs. The history of the telephone, this article argues, is essential to understanding the L.A. region's multi-nucleated development and its economic structure.

Abstract:

Purpose The aims of this study are to review the literature examining the arguments for and against the telephonic qualitative research interviews, to develop criteria for assessing when the use of the telephone is suitable in qualitative research and if suitable to offer detailed strategies for the effective use of this data collection instrument. Design/methodology/approach The study is a thematic analysis of the literature, informed by the researchers’ experiences using the telephone, computer-based audio and face-to-face interviews for an accounting research project involving 50 semi-struc

Abstract:

The ownership of mobile telephones is now almost universal amongst the teenage population of the United Kingdom. Such telephones are a potential source of electromagnetic interference to medical equipment. We describe a case of troublesome interference with an electrocardiogram recording in a teenage patient whose mobile telephone was left switched on during a visit to hospital. This is likely to be a common reason for poor quality electrocardiographic recordings.

Abstract:

The objective of this study was to evaluate the feasibility of using computer assisted telephone interviewing (CATI) as a method for obtaining information on reproductive health in Brazil. A total of 998 eligible women for the study were selected to answer a questionnaire through computer- assisted telephone interviewing undertaken by trained interviewers. The outcomes of each telephone contact attempt were described. Differences between groups were assessed using the χ2 test. Phone contact was made in 60.3% of the attempts and 57.5% of the interviews were completed. The success rate improved

Abstract:

Communication through voice call leads to significant growth in technology in distant areas where two or more people from opposite ends of world will connect. This research describes a case study of voice call transfer service. This research aims at designing a system that will allow Android users to communicate over Wi-Fi. This design is able to transfer voice of incoming telephone caller over Wi-Fi network at real time through UDP. It uses client/server architecture: Server for receiving telephone call and transferring voice (one user) and client for receiving incoming caller voice and enabl

Abstract:

Any artefact – a hammer, a telescope, an artificial hip – may malfunction. Conceptually speaking, artefacts have an inherent normative aspect. I argue that the normativity of artefacts should be understood as part of reality, and not just “in our concepts.” I first set out Deflationary Views of artefacts, according to which there are no artefactual properties, just artefactual concepts. According to my contrasting view – the Constitution View – there are artefactual properties that things in the world really have. For example, there is a property of being a telephone per se; we apply our conce

Abstract:

The limited narrow band (LNB) speech signal spread in the range of 300 to 3400Hz used in public switched telephone networks results in poor-quality telephony speech. Bandwidth extension techniques are performed to expand the frequency range from LNB speech to a clear wideband (CWB) speech signal range of 50Hz-7000Hz over existing public telephone networks. In this paper, a novel robust speech bandwidth extension algorithm by Discrete Wavelet Transform- Discrete Cosine Transform- Based Data Hiding (DWT-DCT-DH) Hybrid transform model was used to spread the out-of-band (3400Hz to 7000Hz) speech f

Abstract:

The scientific ways that led the American radio engineer Michael Pupin to the development of telephone technologies aimed at improving the quality of an audio signal when it is transmitted over long distances are considered. Pupin’s important inventions in the field of long-distance telephony are investigated. His theories of using inductors to reduce the attenuation of the transmitted telegraph and telephone signal over the cable by artificially increasing its inductance are described. Attention is paid to the dispute between Pupin and Campbell in the primacy of the invention of load coils an

Abstract:

This study set out to systematically measure the effect of using various candidate microphones for acoustic coupling of hearing aids to a telephone receiver. Intelligibility of words was determined for three microphones and three levels of interfering noise for a total of nine conditions. The subjects all had moderate hearing loss. It was found that microphones that exhibit pressure gradient sensitivity can, when properly positioned relative to the telephone receiver, increase intelligibility scores significantly. Results show that comparable listening performance is achieved with a pressure g

Abstract:

INTRODUCTION Patients with minor anorectal conditions are frequently reviewed at an 8-week out-patient appointment (OPA). This study was designed to assess whether telephone follow-up could reduce OPA numbers whilst maintaining patient satisfaction. PATIENTS AND METHODS Over an 11-month period, 46 patients (23 male) underwent banding of haemorrhoids and 14 were prescribed medical treatment for fissure-in-ano (3 male). All were telephoned at 6 weeks and were offered an 8-week OPA if they had continuing problems. Patients were telephoned at a later date by a member of the hospital's patient pane
