We present a new open-source, user-friendly toolkit of two codes$-$SFcollapse1D and NRPyCritCol$-$to study critical phenomena in the context gravitational collapse. SFcollapse1D is C/C++ tool designed to solve problem collapse massless, spherically symmetric scalar fields with ADM formalism spherical-like coordinates. NRPyCritColis collection Python modules that leverage NRPy+ infrastructure ge...

Abstract Mizan Computer Shop is a shop that engaged in the trading sector, especially field of selling computers and supporting accessories. Growing increasing number business actors computer can makes players challenged to be able create unique differentiation clear positioning. So, consumers differentiate from their competitors. Competitive dynamic market conditions make every company should ...

As mobile devices become pervasive, it is increasingly important to build mobile systems and applications that adequately address issues such as energy management and disconnected operation. However, there has been little effort to actually understand how these issues impact device usage. In this work, we present the results of a study of 44 laptop computers. We deployed a measurement tool that...

The rapid development in wireless communications has demanded multiband or wideband antennas to support wireless communication devices such as smart phones, tablets, laptop computers, radar system, satellite communication, airplane, and unmanned airborne vehicle (UAV) radar. It has also demanded compact wireless devices that allow more space to integrate other electronic components. The aim of ...

Networked Control Systems over mobile ad-hoc networks have drawn the attention of the researchers because of its suitability in various ad-hoc applications. This paper presents the investigation of such systems using both real wireless communication and co-simulation of MATLAB and OPNET. The plant and the wireless node models are simulated on a computer by MATLAB and OPNET, respectively. The co...

Working with native speakers to find out about a language is one of the most rewarding and enjoyable activities in which linguists engage. Much of the crucial work to ensure a successful fieldwork experience is conducted in advance of actually collecting data in the field. Background work on the language should include locating all possible sources of data. Digital recorders and laptop computer...

 In most engineering colleges, giving lectures for 300 or 400 students is a practical necessity. Most lecture theatres are large and when filled up, they're intimidating to the average student and do not invite students to an active participation. They also restrict the teacher's opportunities to interact with the students. In this paper we describe a “proofof-concept” system developed at Oslo...

Emissions in aircraft communication and navigation bands are measured for the latest generation of wireless phones. The two wireless technologies considered, GSM/GPRS and CDMA2000, are the latest available to general consumers in the U.S. A base-station simulator is used to control the phones. The measurements are conducted using reverberation chambers, and the results are compared against FCC ...

There is hardly a more pervasive trend in the world today than communications. The momentum towards anytime, anywhere and any-type of communication is fueled by advances in radio frequency technology, near-exponential sales of laptop computers and personal digital assistants (PDAs), as well as new models of business that expect and rely on instantaneous information availability. The commonly ro...

Currently, data visualization systems employ a variety of techniques and user interface components to facilitate interaction on mouse-based desktop and laptop computers. However, the same is not true for interaction on touch-based devices such as tablets and mobile phones. Data visualization has yet to become pervasive there and it is not clear what interactive operations should be provided and...
