Adoption of Modern Paddy Farming Practices Among the Farmers in a Mahaweli Settlement Scheme in Sri Lanka
The main purpose of the study was to determine the
adoption and level of adoption of modern paddy farming
practices among the farmers in the Galnewa Block of System H in
the Mahaweli territory of Sri Lanka. The study also attempted
to estimate the relationship between adoption and yield. In
addition, the study examined the relationships between adopt ion
and ascertained factors derived from factor analysis. It
further analysed the extent of adoption and non-adoption, the
characteristics of adopters and non-adopters, the practices
which were adopted and not adopted, and reasons for nonadoption. The study used the survey method supplemented by
observations,unstructured interviews, and secondary data
Non-Orthogonal Multiple Access for mmWave Drones with Multi-Antenna Transmission
Unmanned aerial vehicles (UAVs) can be deployed as aerial base stations (BSs)
for rapid establishment of communication networks during temporary events and
after disasters. Since UAV-BSs are low power nodes, achieving high spectral and
energy efficiency are of paramount importance. In this paper, we introduce
non-orthogonal multiple access (NOMA) transmission for millimeter-wave (mmWave)
drones serving as flying BSs at a large stadium potentially with several
hundreds or thousands of mobile users. In particular, we make use of
multi-antenna techniques specifically taking into consideration the physical
constraints of the antenna array, to generate directional beams. Multiple users
are then served within the same beam employing NOMA transmission. If the UAV
beam can not cover entire region where users are distributed, we introduce beam
scanning to maximize outage sum rates. The simulation results reveal that, with
NOMA transmission the spectral efficiency of the UAV based communication can be
greatly enhanced compared to orthogonal multiple access (OMA) transmission.
Further, the analysis shows that there is an optimum transmit power value for
NOMA beyond which outage sum rates do not improve further
Identifying Relationships Among Sentences in Court Case Transcripts Using Discourse Relations
Case Law has a significant impact on the proceedings of legal cases.
Therefore, the information that can be obtained from previous court cases is
valuable to lawyers and other legal officials when performing their duties.
This paper describes a methodology of applying discourse relations between
sentences when processing text documents related to the legal domain. In this
study, we developed a mechanism to classify the relationships that can be
observed among sentences in transcripts of United States court cases. First, we
defined relationship types that can be observed between sentences in court case
transcripts. Then we classified pairs of sentences according to the
relationship type by combining a machine learning model and a rule-based
approach. The results obtained through our system were evaluated using human
judges. To the best of our knowledge, this is the first study where discourse
relationships between sentences have been used to determine relationships among
sentences in legal court case transcripts.Comment: Conference: 2018 International Conference on Advances in ICT for
