This work presents an efficient data service scheme for location dependent data/objects in a cellular mobile network. It is developed around the hardware structure of cellular automata ( ). The hardware acts as a search engine and performs computation for the data service at a high speed. An encoding technique is reported for the cellular network space that suits effective design of the hardwar...

The Space Telescope Imaging Spectrograph (STIS) is a versatile, general purpose instrument installed aboard the Hubble Space Telescope in February, 1997. During the following Servicing Mission Orbital Verification (SMOV) period, STIS has been made operational and aligned, and initial checkout and calibration completed. The overall optical performance goals have largely been achieved and a summa...

Nebuliser drug delivery units were reused in 15% of paediatric wards participating in a national survey, while routine servicing and written information was provided by only half the wards issuing home nebulisers. Written information should be developed as a national resource, and further research on optimal cleaning practices is required.

This article examines the possibility of determining the indicators for the qual-ification of personnel servicing electrical installations based on statistical data based on the frequency and duration of the work carried out by a group of electrical engineers to eliminate the failure. And also the subsequent transition to the time characteristics, showing the productivity of the work of a separ...

S oftware engineers have traditionally considered any work after initial delivery as simply software maintenance. Some researchers have divided this work into various tasks, including making changes to functionality (perfec-tive), changing the environment (adaptive), correcting errors (corrective), and making improvements to avoid future problems (preventive), 1 but still most have considered m...

Mobile robots are increasingly being used for tasks like remote surveillance, sensing and maintenance. Some of these tasks are critical and require intelligent decision making for successful completion. It is not always possible to rely exclusively on robot level intelligence to make high impact decisions and hence human supervision is needed during task execution. To facilitate human-in-the-lo...

Read and write requests from a processor contend for the main memory data bus. System performance depends heavily on when read requests are serviced since they are required for an application’s forward progress whereas writes do not need to be performed immediately. However, writes eventually have to be written to memory because the storage required to buffer them on-chip is limited. In modern ...

Architecture frameworks are tools for managing system complexity by structuring data in a common language and format. By characterizing the form, function, and rules governing systems, architecture frameworks serve as a communication tool to stakeholder communities with different views of the system and facilitate comparative evaluation across architectures. The goal of this research is to expl...
