Each factor semigroup of a free restriction (ample) semigroup over a congruence contained in the least cancellative congruence is proved to be embeddable into a W -product of a semilattice by a monoid. Consequently, it is established that each restriction semigroup has a proper (ample) cover embeddable into such a W -product.

This study aimed to find the role of image congruence in context robotic coffee shops. More specifically, this proposed that three types including actual self-image congruence, ideal and social aid increase brand attitude. In addition, it was attitude positively affects attachment loyalty. For this, collected data from 325 customers who used The analysis results indicated have a positive influe...

A subcarrier spectral amplitude coding optical code division multiple access system using the Khazani-Syed code with Complementary subtraction detection technique is proposed. The proposed system has been analyzed by taking into account the effects of phase-induced intensity noise, shot noise, thermal noise and intermodulation distortion noise. The performance of the system has been compared wi...

fuzzy order congruences play an important role in studying the categoricalproperties of fuzzy posets. in this paper, the correspondence between the fuzzyorder congruences and the fuzzy order-preserving maps is discussed. we focus onthe characterization of fuzzy order congruences on the fuzzy poset in terms ofthe fuzzy preorders containing the fuzzy partial order. at last, fuzzy completecongruen...

In 2003, Zhao discovered a curious congruence involving harmonic series and Bernoulli numbers: for any odd prime [Formula: see text] where is the text]th number. This was generalized by Wang Cai in 2014, Cai, Shen Jia 2017 replacing summation modulus with an power, product of two powers, respectively. particular, proposed conjectural congruence: positive integer factor such that this paper, we ...

The aim of this paper is to extend results established by H. Onoand T. Kowalski regarding directly indecomposable commutative residuatedlattices to the non-commutative case. The main theorem states that a residuatedlattice A is directly indecomposable if and only if its Boolean center B(A)is {0, 1}. We also prove that any linearly ordered residuated lattice and anylocal residuated lattice are d...

the purpose of this research was identifying factors affecting the development of processing and complementary industries of date palm in khouzestan province. the method of research was causal comparative. the population of this research was managers in processing and complementary industries of date palm products of khouzestan province (n=100). the return rate was 94% (n=94). by census method...

Every quasigroup (loop, Bol loop, group, respectively) is isomorphic to the factor of a subdirectly irreducible quasigroup (loop, Bol loop, group, respectively) over its monolithic congruence.

BACKGROUND Motor imagery (MI) capacity may be altered following stroke. MI is evaluated by measuring temporal congruence between the timed performance of an imagined and an executed task. Temporal congruence between imagined and physical gait-related activities has not been evaluated following stroke. Moreover, the effect of cognitive dysfunction on temporal congruence is not known. OBJECTIVE...

We tested the hypothesis that only 3 factors of personality description are replicable across many different languages if they are independently derived by a psycholexical approach. Our test was based on 14 trait taxonomies from 12 different languages. Factors were compared at each level of factor extraction with solutions with 1 to 6 factors. The 294 factors in the comparisons were identified ...
