We study the ALT algorithm [19] for the point-to-point shortest path problem in the context of road networks. We suggest improvements to the algorithm itself and to its preprocessing stage. We also develop a memory-efficient implementation of the algorithm that runs on a Pocket PC. It stores graph data in a flash memory card and uses RAM to store information only for the part of the graph visit...

In this paper we describe an infrastructure based on an existing, commercially available, GSM mobile phone for achieving .connectivity between digital cameras and an Internet Website. Pictures are loaded from a standard digital camera, or compact flash card, by an embedded appliance, which establishes the Internet connection and controls the transfer of pictures from the camera to a remote webs...

The goal of this project is to develop a mobile device for transmitting images for the aftercare of surgical patients within the framework of the competence center TELTRA. After designing and evaluating different platforms and cameras, it was decided to develop for a compact flash camera card and an HSCSD modem which is based on and can be plugged into a pocket PC. The recorded images are sent ...

We selected the macro function in the digital camera, switched off the flash, and turned on the polarized light of the dermatoscope. We ...

An increasing amount of personal data is automatically gathered and stored on servers by administrations, hospitals, insurance companies, etc. Citizen themselves often count on internet companies to store their data and make them reliable and highly available through the internet. However, these benefits must be weighed against privacy risks incurred by centralization. This paper suggests a rad...

Data remanence is the residual physical representation of data that has been erased or overwritten. In non-volatile programmable devices, such as UV EPROM, EEPROM or Flash, bits are stored as charge in the floating gate of a transistor. After each erase operation, some of this charge remains. Security protection in microcontrollers and smartcards with EEPROM/Flash memories is based on the assum...

The future trend of controller integrated circuit (IC) for micro hard disk driver (HDD) is to be lighter, thinner, shorter and smaller. The storage capacity and unit cost of micro HDD is lower than of flash memory card. The optimal packaging manufacturing process for driver IC for micro HDD is Chip Scale Package (CSP). However, the production and assemble process for CSP is much more difficult....

This paper introduces the wavelet image two-line (Wi2l) coding algorithm for low complexity compression of images. The algorithm recursively encodes an image backwards reading only two lines of a wavelet subband, which are read in blocks of 512 bytes from flash memory. It thus only requires very little memory, i.e., a memory array for two wavelet subband lines, an array to store intermediate tr...

This study aims to determine the influence of inquiry learning model with flash card media on competence IPAS knowledge grade IV. type research is a pseudo-experimental nonequivalent control group design. The population in this was 91 Samples taken purposive sampling technique. collection competency data carried out using test method form an ordinary multiple-choice objective 30 questions. obta...
