Waypoint Navigation System Implementation via a Mobile Robot Using Global Positioning System (GPS) and Global System for Mobile Communications (GSM) Modems

Global Positioning System (GPS) Bias Correction and

Seasonal variation in habitat selection by the mountain goat Oreamnos americanus is not well understood due to the difficulties of monitoring animal movement in all months of the year. The use of global positioning system (GPS) wildlife telemetry collars offers an opportunity to overcome this obstacle, however satellite acquisition problems associated with GPS wildlife telemetry collars create ...

گزارش یک مورد: ارسال فشار خون و نبض بیمار به پزشک با استفاده از سیستم Global system for Mobile Communications

 Background: Hypertension is a common chronic disease with increasing prevalence worldwide. Regular close monitoring of blood pressure is key point of hypertension management. Home monitoring of blood pressure has its own problems such as lack of early access to a physician in case of emergency. In this study we have designed a device that could send the patient’s self-measured blood pre...
