Task allocation among social insect workers is an ideal framework for studying the molecular mechanisms underlying behavioural plasticity because workers of similar genotype adopt different behavioural phenotypes. Elegant laboratory studies have pioneered this effort, but field studies involving the genetic regulation of task allocation are rare. Here, we investigate the expression of the forag...

Harvesting rain-fed chickpeas (Cicer arietinum L.) from fallow fields in developing countries is currently a manual process performed by laborers in a tedious manner at a low level of efficiency. A tractor-pulled harvester was built in which a chain conveyor transfer harvested material. A tractor-mounted harvester was then redesigned, which incorporated a modified stripper header to detach pods...

This paper introduces and compares different benchmark parameters for the performance of electromagnetic energy harvesters, including the bottom-up (power according to the harvester model) as well as the top-down view (maximum power that can be generated within a volume) and considering the dependency and scaling of geometrical and physical parameters, such as the mechanical damping. The compar...

Using CAN (controller area network) field bus and iCAN protocol, an integrated measuring and controlling system for combine harvester is constructed in this paper. ARM is used as the processor of host computer. Lower computers are several measuring and controlling modules of combine harvester. Host computer communicates with lower computers through CAN bus. Information between measurement and c...

This paper discusses a RF power harvester optimized for sensitivity and therefore wireless range, for applications requiring intermittent communication. The RF power harvester produces a 1V output at -32dBm sensitivity and 915MHz. This is achieved using a CMOS rectifier operating in the subthreshold region and an off-chip impedance matching network for boosting the received voltage. Equations p...

In this paper, a new hybrid routing protocol is presented for low power Wireless Sensor Networks (WSNs). The new system uses an integrated piezoelectric energy harvester to increase the network lifetime. Power dissipation is one of the most important factors affecting lifetime of a WSN. An innovative cluster head selection technique using Cuckoo optimization algorithm has been used in the desig...

This paper describes the implementation plan of BDJur Consortium – Juridical Digital Library. The goal of this project was to create a juridical information network, with digital repositories and full text documents, linking the Brazilian Judiciary. The seven phases established are pointed out in this work (1. preliminary studies and evaluation of the open sources platforms; 2. installation, tr...

This paper presents the design and evaluation of a novel permanent magnet (PM) energy harvesting system for scavenging electrical energy from ambient vibrations. A two-phase tubular linear PM vibration energy harvester consisting of a mover attached with permanent magnets and a slotted stator with built-in two-phase electromagnetic coils is proposed to convert vibrational kinetic energy into el...
