In our study, a mobile application is developed which is able to capture the guitar sounds played in real time and detect notes using signal processing techniques. In this application, user's performance is evaluated by comparing the played and the expected notes for any chosen song. Additionally, songs can be prepared manually within the application or automatically by transforming guitar notes provided...
Mobile network security and management are becoming important issues, due to the rapid development and widespread of the mobile network. Application traffic identification is a critical technology to resolve these issues. A variety of traffic classification methods on desktop applications are no longer effective in mobile network, because the majority of mobile traffic is carried over HTTP without...
With the increasing demand of beef meat, it was found that several butchers in the market sometimes do the mixing of flesh meat between beef and pork. The price of beef meat is much more expensive than pork that also triggers such practices. It is of course very detrimental to consumers, especially for Moslems who are forbid to eat pork. Development of software technology, such as in mobile application...
Recent years have witnessed the fast growth of the use of the mobile applications (a.k.a. "apps"). Detecting similar apps is a basic problem in the app ecosystem. It is not only beneficial to app search and recommender systems, but also helpful for people to discover new apps. State-of-the-art studies defined several app similarity functions by the metainformation of apps, such as descriptions...
The paper examines how a gamification approach can enhance and enrich the learning experience of personal care givers (PCGs) for people with disabilities and older people (potential or in active employment). Using game elements that pervade the M-Care mobile PCG training application, users are given the opportunity to self-assess their newly acquired knowledge and through a rewards system they are...
W artykule przedstawiono koncepcję materiałów dydaktycznych, udostępnianych na urządzeniach przenośnych, przeznaczonych do zastosowania w sztolniach szkoleniowych. Przedstawione rozwiązanie oparte jest na autorskim oprogramowaniu opracowanym w ITG KOMAG, umożliwiającym prowadzenie szkoleń zarówno w części teoretycznej, jak i praktycznej. Forma opracowania materiałów dydaktycznych umożliwia ich zastosowanie...
In this paper we present a novel interactive platform for the operational support and training of the forest fire volunteer groups that are accredited through the mechanisms of Civil Protection Services. The proposed system is based on mobile and web technologies, fire simulation techniques and shortest-path routing calculation. The system consists of a mobile application (client) allowing the volunteers...
With the increasing number of mobile Apps developed, they are now closely integrated into daily life. In this paper, we develop a framework to predict mobile Apps that are most likely to be used regarding the current device status of a smartphone. Such an Apps usage prediction framework is a crucial prerequisite for fast App launching, intelligent user experience, and power management of smartphones...
This paper proposes methods for measuring size and distance of target objects by using mobile devices. For close-range measurement of a size of an object, users must hold the device close to the object and drag it along a desired direction. We develop a new approach for estimating a dragging distance of the device using acceleration signals retrieved from a three-axis accelerometer embedded on it...
Modern mobile devices and networks permit to develop applications that reduce the language barrier for tourists and visitors in foreign countries. This paper describes a mobile application built on a distributed architecture that allows tourists to obtain additional information about location names and menu entries in Arabic language. By simply taking a photo, translation and additional information...
A least-squares (LS) channel estimation technique is investigated to extend pseudo-random-postfix orthogonal-frequency-division multiplexing (PRP-OFDM) techniques onto mobile applications in rapidly time-variant frequency-selective fading environments. The proposed method exploits self-interference cancellation to effectively reduce a variety of interferences; and thus, it can overcome not only frequency-selectivity...
This paper presents a location based active promotion technique called PLAP for mobile environment. While most of the previous location aware systems have utilized specialized sensors or artificial markers, PLAP provides real-time place recognition capability using camera which is nowadays attached to most mobile systems. An active clothes promotion system is built using PLAP and provides users the...
