Today Robotics plays an integral role in all aspects of manufacturing, medicine, industries, home basic and more and it will take on even greater importance in the future. Controlling the robot by using GSM Module is a most suggested mechanism for mobile robot which has the capability of changing directions for the long range distances. In this design, fire detection and controlling method usin...

The method of moments (MOM) in conjunction with the generalized scattering matrix (GSM) approach is proposed to analyze transverse multilayered structures in a metal waveguide. The formulation incorporates ports as an integral part of the GSM formulation and so the resulting model can be integrated with circuit analysis. The proposed technique permits the modeling of interactive discontinuities...

GSM is the most popular standard for mobile phones in the world. In spite of the tremendous market growth, however, the GSM system has the fatal security problems in TMSI allocation protocol. These problems are right user authentication and location privacy. In this paper, we propose the secure TMSI allocation mechanism using the certification concept to solve these problems. The proposed mecha...

Background: People who use home blood glucose monitors may use their mobile phones in the close vicinity of medical devices. This study is aimed at investigating the effect of the signal strength of 900 MHz GSM mobile phones on the accuracy of home blood glucose monitors.Methods: Sixty non-diabetic volunteer individuals aged 21 - 28 years participated in this study. Blood samples were analyzed ...

INTRODUCTION Ultrasonic tissue characterization of the carotid wall using gray-scale median (GSM) reflects its composition and low-GSM plaque is considered to be unstable. The present study evaluated the effect of alogliptin, a dipeptidyl peptidase-4 inhibitor, on the longitudinal change in GSM, an index of the tissue characteristics of the carotid wall, in patients with type 2 diabetes (T2DM)....

Grain Scale Management (GSM) is a crucial factor in ensuring national food security. However, countries facing rigid resource constraints and complex land tenure relationships, the strategy of promoting large-scale grain management through rights transfer may not be sustainable. Therefore, based on traditional agricultural division labor theory, we analyze mechanism rationality Agricultural Pro...

In this paper a method to facilitate M2M communication using existing GSM networks is proposed – as M2M devices primarily use SMS as their data bearer, the focus is on increasing the number of devices that can use the associated GSM signaling channels at a time. This is achieved by defining a new class of low mobility, static M2M devices which use a modified physical layer control frame structu...

The proposed framework describes a service for users that gives them the ability to make gsm calls from their smartphones without revealing their identity. The principle to achieve that is simple: instead of using your cell phone to make a call, pick somebody else’s phone to do so. We proposed an infrastructure of smartphones, sip registrars and sip proxies to provide caller anonymity. We devel...

Considering the widespread adoption of smartphones in mobile communications and the well-established resource sharing use in the networking community, we present a novel mechanism to achieve anonymity in the Global System for Mobile Communications (GSM). We propose a Voice over Internet Protocol infrastructure using the Session Initiation Protocol (SIP) where a smartphone registers on a SIP reg...

Mobile users need more capacity and higher velocity to work with new data applications. In order to satisfy these requirements, mobile systems of third generation were created and they are established every day in more places. Consequently second and third generation of system have to coexist. In this paper is presented a study about the coexistence between GSM and UMTS, the most popular system...
