This paper reports on issues related to the use of mobile phones by women aged 60 years and over. The study started with a series of focus group discussions, which covered usage patterns, problems, benefits, ideal phone design, and desired and unwanted features. It then moved to an exploration of the group’s cooperative learning process when encountering an unfamiliar mobile phone. The issues r...

Quantum mechanics can speed up a range of search applications over unsorted data. For example, imagine a phone directory containing N names arranged in completely random order. To find someone’s phone number with a probability of 50%, any classical algorithm (whether deterministic or probabilistic) will need to access the database a minimum of 0.5N times. Quantum mechanical systems can be in a ...

We present a lensfree digital microscopy platform implemented on a cell-phone. It operates based on digital in-line holography and provides a compact and light-weight alternative to conventional microscopes, such that the cell-phone is modified with an inexpensive attachment weighing only ~38 grams. This lensfree cell-phone microscope captures holographic images of the objects which are then ra...

Electronic Customer relationship management performance CRM is a comprehensive business and marketing strategy that integrates people, process, technology and all business activities for attracting and retaining customers over the internet and mobile phone to reduce costs and increase profitability by consolidation the principles of customer loyalty. Therefore, the results of CRM performance ar...

Along with the ever increasing popularity of cellular phones, improving recognition accuracy in cellular phone speech has become an issue of growing concern. However, the distortion caused by current low-bit rate speech CODEC is nonlinear, so compensating for distortion by applying only a conventional CMN which assumes distortion is a stationary linear transfer on the cepstrum domain is di cult...

electromagnetic radiation emitted by cell-phones is a new health hazard, especially when they are used inside closed metal bodies such as cars, elevators etc. the modern wireless devices like bluetooth further enhance the effect of this radiation. the present studies were taken to get quantitative information about the actual power density levels to which a human brain is exposed inside a vehic...

In this paper we assess the potential of rich tactile notifications on mobile phones. Many mobile phone users use vibration output for various types of notification on their phone. Currently, tactile output in phones is limited to one single actuator that can potentially present patterns based on different vibration intensities over time. To explore the possible design space, we conducted exper...

Including information distributed over intervals of syllabic duration (100–250 ms) may greatly improve the performance of automatic speech recognition (ASR) systems. ASR systems primarily use representations and recognition units covering phonetic durations (40–100 ms). Humans certainly use information at phonetic time scales, but results from psychoacoustics and psycholinguistics highlight the...

INTRODUCTION Mobile phones are ubiquitous. There are over 2.5 billion mobile phone subscribers world wide. It is not uncommon for mobile phones to be the first object that people interact with in the morning and they are quite often one of the last things people interact with in the evening before going to sleep [3]. Though mobile phones play a significant role in the daily lives of billions of...

cell phone is now considered by its users as an entertainment and also a media in addition to serving them as a telecommunication instrument and having a cell phone has more implications for them. in this study, the author has tried to discuss these additional functions and implications through an online survey of a number of cell phone users regardless of its communicational functions  the res...
