In order to provide suitable blood transfusion samples to patients, the blood bag should be kept at a uniformly maintained temperature to prevent deterioration during transportation. Therefore, this paper presents a blood monitoring and management system for use in hospitals. This system may continuously report the temperature of the blood bank refrigerator, track the location of a blood bag to...

This paper describes mobility management for the third-generation mobile networks. We focus on the evolution from General Packet Radio Service (GPRS) to Universal Mobile Telecommunication System (UMTS). In this evolution, the radio access network UTRAN has been introduced, and radio-related management is moved from the core network to UTRAN. We elaborate on how this architecture change affects ...

In this paper, we study WSN design, as a multi-objective optimization problem using GA technique. We study the effects of GA parameters including population size, selection and crossover method and mutation probability on the design. Choosing suitable parameters is a trade-off between different network criteria and characteristics. Type of deployment, effect of network size, radio communication...

ABSTRACT The study assessed the use of rural radio as agricultural information dissemination tool among farmers in Dekina Local Government Area of Kogi State. The specific objectives were to: describe the socio-economic characteristics of the respondents, identify rural and agricultural programmes normally aired on radio, find out the level of patronage of the programmes, identify the convenien...

The Communication Based Train Control (CBTC) system reports the real-time train location from an onboard system to a wayside systems and transmits the movement authority through radio communication from the wayside system to the onboard system, and it shall increase railway capacity by allowing the highdensity train control through high information transmission amount between the wayside ATP/AT...

The concept of cognitive radio has arisen as a generalization of the principle of multiple access in radio channels initially developed in the late sixties and early seventies including the pioneering methods of channel sharing depicted in the ALOHA and CSMA protocols. The intent is to go beyond the context of a single homogeneous system or network with a number of terminals that operate accord...

This paper discusses the need for joint link level and system level simulations for thirdgeneration mobile radio systems and points out a way of implementing them in SDL. The simulation of third-generation mobile radio interfaces is a particular challenge to computational power. Complex systems are needed to support the demands of ATM services and high data of rates up to 2 Mbit/s in the UMTS b...

This system can fully prevent from human and financial losses that may cause by a variety of toxic and flammable gases. Its application of this system is in residential, commercial office, factories and etc. The mechanism of system is by radio waves. This system for preventing probable risks simultaneously cuts the electricity and gases of selected environments, the horn of alarm risk brought t...
