Energy-harvesting technologies are fundamental in enabling the realization of ‘‘zero-power’’ wireless sensors and implementing the Internet-of-Things (IoT) and machine-to-machine (M2M) communication. Their increasing utilization in low-power and power-efficient sensors and electronics could potentially find application in numerous critical areas ranging from health, agricultural, structural hea...

Background: The post-harvesting process of medicinal plants such as drying operation and storage conditions has great influence on their quality and quantity of the active ingredients. Objective: The aim of this experiment was to investigate the effect of pre-drying operation and also storage conditions and duration on the essential oil content and composition of Thymus daenensis. Methods: A ...

Recent advances in ultra-low power chip design techniques, many originally targeting wireless sensor networks, will enable a new generation of body-worn devices for health monitoring. We utilize the state-of-the-art in low power RF transmitters, low voltage boost circuits, subthreshold processing, biosignal front-ends, dynamic power management, and energy harvesting to realize an integrated rec...

This paper describes the key system components of a team of three tractors in a peat moss harvesting operation. The behavior and actions of the tractors were designed to mimic manual harvest operations while maintaining a safe operating environment. To accomplish this objective, each of the three tractors was equipped with a bolt-on automation package, and a human operator (team leader) was giv...

Bluetooth Low Energy beacons have immense potential to provide rich contextual information to smartphone applications and people by bridging the physical and digital worlds. Beacons perform the simple operation of periodically chirping URLs, locations, and other pointers, however, today’s beacons use relatively large and battery powered implementations. To truly make these beacons pervasive, th...

Devices in future Internet of Things (IoT) will be scavenging energy from the ambiance for all their operations. They face challenges in various aspects of network organization and operation due to the nature of ambient energy sources such as, solar insolation, vibration and motion. In this paper we analyze the classical two-way algorithm for neighbor discovery (ND) in an energy harvesting IoT....

As precision farming technologies are on the rise and witness a tremendous development, consequently, machine settings and harvesting machines themselves are getting more and more complex. Although the Ag contractor business is growing in whole, the number of fulltime employees is permanently reduced at the same time. As a consequence, farmers depend more and more on seasonal workers who are no...

Purpose. To describe the long-term results of frontalis suspension using autogenous fascia lata in children with congenital ptosis under 3 years old. Methods. Forty three-eyes of 35 patients were enrolled in the study. Frontalis suspension using autogenous fascia lata was performed in all patients. The postoperative eyelid level, ptosis recurrence, visual acuity, and cosmetic results were evalu...
