Many changes have been taking place in Oregon's agriculture.
Average size of farms has increased. The trend is toward fewer
but larger, highly mechanized farms, leading to changed demand
for farm machinery and consequently changes in farm machinery
firms to meet the changing demands of farmers. In general, the
research...
A Brushless, Doubly Fed Machine (BDFM) attempts to combine the advantages
of conventional induction and synchronous types of electrical machines by its unique
architecture. The validation of BDFM designs in an actual test environment requires the
estimation of the BDFM model parameters from actual experimentation. Accurate values
for the parameters...
An electro-dynamic Magnetic Levitation vehicular system has been
modelled and studied. In practice, a MagLev vehicle will consist of a
number of cars which are mechanically coupled to each other. It is
reasonable to assume that each of these cars will be independently
controlled with the help of a supervisory...
In this thesis, we develop a simulator for estimating the energy consumed in executing tasks on a mobile device - the Palm Pilot. We measured the energy consumed by each instruction of the device's assembly language and incorporated these measurements into a public domain emulator for the Palm Pilot. This...
The widespread use of TCP as a transport layer protocol for mobile ad-hoc networks and wireline networks has motivated the need to make its implementation highly power efficient specially with respect to ad hoc radio networks. Over the past years many researchers have developed energy efficient protocols for mobile ad-hoc...
The problem of ensuring Quality of Service (QoS) on a TCP/IP based fixed-infrastructure network has been well studied and several working proposals exist. An allied problem is that of ensuring QoS on an ad-hoc wireless network, where the requirements are similar, but the operating conditions are different enough to warrant...
Ad Hoc networks are multi-hop wireless networks consisting of mobile hosts. They do not have any pre-existing network infrastructure and are characterized by constantly changing topology, limited battery power and bandwidth. Typical applications of such networks are battlefield networks, medical relief during natural calamities or disasters, conference room networking, and...
Power is a valuable resource. It is invaluable when for mobile devices. Mobile devices, due to their mobility cannot get a continuous source of power and derive their power from a battery contained in them. The main consumer of power in the mobile is its transmitter. With a limited power...
In the spring and summer of 1975 a study was conducted under natural conditions to determine whether wild adult Dermacentor andersoni Stiles would transmit Anaplasma marginale to cattle. The ticks were collected from the range pasture of Squaw Butte Experiment Station where anaplasmosis is enzootic and D. andersoni is indigenous....
The effects of the inherent transmissibility of the
virus and of the inherent transmitting ability of aphids
on the transmission of bean yellow mosaic virus (BYMV)
were studied along with four virus-vector relationships of
BYMV and the green peach aphid, Myzus persicae (Sulz.).
In addition, investigations were made on the...
