The masking-based speech enhancement method pursues a multiplicative mask that applies to the spectrogram of input noise-corrupted utterance, and a deep neural network (DNN) is often used to learn the mask. In particular, the features commonly used f
or automatic speech recognition can serve as the input of the DNN to learn the well-behaved mask that significantly reduce the noise distortion of processed utterances. This study proposes to preprocess the input speech features for the ideal ratio mask (IRM)-based DNN by lowpass filtering in order to alleviate the noise components. In particular, we employ the discrete wavelet transform (DWT) to decompose the temporal speech feature sequence and scale down the detail coefficients, which correspond to the high-pass portion of the sequence. Preliminary experiments conducted on a subset of TIMIT corpus reveal that the proposed method can make the resulting IRM achieve higher speech quality and intelligibility for the babble noise-corrupted signals compared with the original IRM, indicating that the lowpass filtered temporal feature sequence can learn a superior IRM network for speech enhancement.
The present study aims to identify the similarities and differences in the view of
values between the main social theoretical trends adopted as assets to discuss topics of
interest to sociology. These trends agreed in principle to give quality of o
bjectively to the
values, and differed about their interpretation, understanding and change. We resort to the
comparative approach to find the disclosure of similarities and differences. This approach
is the closest approaches of social research to the nature of the studied subject, mainly in
the study of social phenomena. We will also turn to the analysis of the content according to
the requirements of the study when determining the point of view concerning the values in
this direction or that as stated by the first founders of these trends, namely Emile Durkheim
functional trend, and the founder of the rules of the approach in sociology, and Karl Marx,
the founder of marital comprehension of history and social life, Max Weber, the founder of
sociology of understanding, a pioneer of the ideal model of social analysis. The efforts
made by the founders to study social problems and phenomena, which have been adopted
as the basis of research in sociology, the researcher can draw from their general context
their view of values and reveal the underlying aspect of their studies around them,
especially if we know that each of the first pioneers did not highlight directly on the values
concept.
The research looks at the image of the ideal man represented by the
character of prophet Mohammed (pba) that is dealt with by Imam Ali in
'NahjulBalaghah' .
The research begins by showing the opinion of some philosophers in
man in general and the
ideal man in particular . then , it moves to deal with
'the ideal man' . the idea that occupies most of the research .it studies that in
accordance with a preface which refines the characteristics of Prophet
Mohammed supervened by one of Imam Ali`s speeches in which he mentions
the characteristics of the prophet (pba)to make it abvious the characteristics of
the ideal man or what the expected image of man should be that's all done in a
mere, distinct , technical , linguistic from .
the research sheds alight on man's different deeds and his multi –
aspect elements prevailing the appealing aspects in the speech and the impact
of technical images , the language , the cadence in exposing the image of the
ideal man- the prophet himself making its context and the speech it put within
very clear .
The thermal exchangers are widely used in the power generating stations and many
refrigeration systems. Activity in the thermal cycle depends on its design and real
calculations.
The aim of our present work, is to find an ideal calculation method
of the working
exchangers parameters and evaluating the used technical engineering soluting.
We discussed the ideal chosen problems and the affecting parameters, and used a
calculating design for a thermal exchanger in the heating and feeding with hot water,
considering these parameters. The proposed designing benefit, could be evaluated from the
final indication that could be expressed by real palpable material.
We found that the ideal parameters choosing could clearly descrese the preparation
costs the heat exchanger blank – form by three times and give full clear proposed
calculation method of all the parameters and its exchanging. This could save of the best
exchanging possibility chosen from the different exchanger.
Feuerbach tried to make the power of love a kind of power that cannot be matched
with any other power as love defeats all his opponents even if God is one of them. Love is
always victorious. That's what made the concept of love in Feuerbach’s ideas
a
distinguished and unprecedented concept comparing to all concepts handled by those
philosophers before him. This kind of love dominates the body and soul together and it is
inseparable from our body, may not live outside our soul, it is the basis of the body and the
essence of the spirit.
Feuerbach wanted to make love a link between a mankind and another so there is no
love if one existence and the other is absent. Feuerbach doesn’t limit himself at this point
but goes on to ignore the existence of human being without being in love or loved by other
person. That who does not love does not exist, even religion has neither benefit nor
importance if it is not based on love because love is the reason and core in other words
love is the reason behind the existence of religion.
The object of this paper is to study the total as substructure of hom (M,N) R
for any two modules R M and R N , one of interesting question, is when the total
of a module N equals the hom (N, J (N)) R .
The object of this paper is to study the locally projective and locally injective
modules. Specifically, this paper is a continuation of study of locally projective

locally injective modules is obtained.
The object of this paper is to study the endomorphism rings of locally
projective and locally injective modules. Specifically, this paper is a continuation
of study of endomorphism rings of locally projective and locally injective modules
to be semipotent rings.
In this scientific paper we dealt with three different types of
homomorphisms between two given ideals in a ring with unity shown as
follows: ring homomorphism, R- module homomorphism and ideal
homomorphism, which were supported by several example
s.
Furthermore, we prove that the family of ideals in a ring R with ring, R -
module and ideal homomorphisms forms the category of ideals of the first,
second and third type, respectively. The next step was dedicated to support all
previous ideals by examples and functor between such categories.
Let M and N be two modules over a ring R. The object of this paper is the study
of substructures of hom (M, N) R such as, radical, the singular, and co-singular
ideal and the total. The new obtained results include necessary and sufficient
conditi
ons the total of a ring R to equal some ideal of R.
