Structural Changes and Ferroelectric Properties of BiFeO<sub>3</sub>-PbTiO<sub>3</sub> Thin Films Grown via a Chemical Multilayer Deposition Method
Thin films of (1-x)BiFeO3-xPbTiO3 (BF-xPT) with x ~
0.60 were fabricated on Pt/Si substrates by chemical solution deposition of
precursor BF and PT layers alternately in three different multilayer
configurations. These multilayer deposited precursor films upon annealing at
700{\deg}C in nitrogen show pure perovskite phase formation. In contrast to the
equilibrium tetragonal structure for the overall molar composition of
BF:PT::40:60, we find monoclinic structured BF-xPT phase of MA type.
Piezo-force microscopy confirmed ferroelectric switching in the films and
revealed different normal and lateral domain distributions in the samples. Room
temperature electrical measurements show good quality ferroelectric hysteresis
loops with remanent polarization, Pr, of up to 18 {\mu}C/cm2 and
leakage currents as low as 10-7 A/cm2.Comment: 14 Pages and 6 figure
Mask & Focus: Conversation Modelling by Learning Concepts
Sequence to sequence models attempt to capture the correlation between all
the words in the input and output sequences. While this is quite useful for
machine translation where the correlation among the words is indeed quite
strong, it becomes problematic for conversation modelling where the correlation
is often at a much abstract level. In contrast, humans tend to focus on the
essential concepts discussed in the conversation context and generate responses
accordingly. In this paper, we attempt to mimic this response generating
mechanism by learning the essential concepts in the context and response in an
unsupervised manner. The proposed model, referred to as Mask \& Focus maps the
input context to a sequence of concepts which are then used to generate the
response concepts. Together, the context and the response concepts generate the
final response. In order to learn context concepts from the training data
automatically, we \emph{mask} words in the input and observe the effect of
masking on response generation. We train our model to learn those response
concepts that have high mutual information with respect to the context
concepts, thereby guiding the model to \emph{focus} on the context concepts.
Mask \& Focus achieves significant improvement over the existing baselines in
several established metrics for dialogues.Comment: AAAI 202
TYPES OF DISABILITY AS PER RIGHTS OF PERSONS WITH DISABILITIES ACT, 2016: A THEORETICAL PERSPECTIVE
Education is an essential part of modern, civilized, advanced and developed society and its progress can never be completed and multidimensional, today when we talk about education, the shape of inclusive education comes to the fore. Due to which normal and disabled get education by sitting at the same table in a school together. Without inclusive education, the education of disabled cannot be given in full and real shape. In the 21st century, the Rights of Persons with Disabilities Act, 2016 came into force, which led to the development of a new consciousness among disabled (Divyangjan, 2021). Under which making disabled aware, bringing disabled into the mainstream of society through inclusive education, use of educational technology, barrier free environment, categorizing the existing 7 to 21 types of disability and increasing many services operates. Article visualizations
