In this paper, we present an OpenCL-based heterogeneous implementation of a computer vision algorithm – image inpainting-based object removal algorithm – on mobile devices. To take advantage of the computation power of the mobile processor, the algorithm workflow is partitioned between the CPU and the GPU based on the profiling results on mobile devices, so that the computationally-intensive ke...

Mobile UNITY refers to a notation system and proof logic initially designed to accommodate the special needs of the emerging field of mobile computing. The model allows one to define units of computation and mobility and the formal rules for coordination among them in a highly decoupled manner. In this paper, we reexamine the expressive power of the Mobile UNITY coordination constructs from a n...

** This research is supported in part by National Science Foundation grant No. EIA-9973465 Abstract Energy saving is the most important issue in wireless mobile computing due to power constraints on mobile units. Data broadcasting is the main method of information dissemination in wireless networks as its cost is independent of the number of mobile hosts receiving the information. A number of d...

MEMS Inertial Measurement Units are available at low cost and can replace expensive units in mobile mapping platforms which need direct georeferencing. This is done through the integration with GNSS measurements in order to achieve a continuous positioning solution and to obtain orientation angles. This paper presents the results of the assessment of the accuracy of a system that integrates GNS...

In 3G mobile terminals the Viterbi Decoder consumes approximately one third of the power consumption of a base band mobile transceiver. Viterbi decoders employed in digital wireless communications are complex and dissipate large power. A low power Viterbi decoder is designed in circuit level using self reset logic and wave pipelining technique is implemented for high speed operation. The Viterb...

Many research projects have defined applications that are claimed to operate in a MANet environment. Consider for instance the notion of a distributed file system which is the concern of a large number of these applications. It appears that most of the proposed solutions require a central server that makes it possible to ensure data consistency, by storing copies of the data from time to time, ...

Mobile robots can be helpful for post disaster management, e.g., to explore hazardous and damaged environments. However, many challenges in various areas have to be solved, e.g., mechanical issues, situation awareness, communication capabilities. We present the interdisciplinary research project Robotic Firefighters (RFF) which addresses some of the IT problems. We take a detailed look at the p...

We consider the problem of maximizing the total connectivity for a set of wireless agents in a mobile ad hoc network. That is, given a set of wireless units each having a start point and a destination point, our goal is to determine a set of routes for the units which maximizes the overall connection time between them. Known as the COOPERATIVE COMMUNICATION PROBLEM IN MOBILE AD HOC NETWORKS (CC...

RenderScript is a set of tools designed by Google to support parallel processing on mobile devices with Android. This tools were designed to run on di erent processing components such as Central Processing Units (CPU), Digital Signal Processors (DSP) and Graphics Processing Units (GPU) and it allows portability between mobile electronics devices such as Tablets and Smartphones. RenderScript has...

HIC-5 is a multidomain LIM protein homologous to paxillin that serves as a molecular scaffold at focal adhesions and in the nucleus. It forms mobile molecular units with LIM-only proteins, PINCH, and CRP2 and translocates in and out of the nucleus via a nuclear export signal (NES). Of note, NES of HIC-5 is distinctive in its sensitivity to the cellular redox state. Recently, the mobile units of...
