In the closure spaces, Boonpok and Khampakdee [1]
were introduced the notion of generalized closed sets and
applied this notion to defined and studied generalized
continuous functions. In this paper, the concept of soft
generalized closed sets in soft closure spaces is
considered to introduce weaker forms of soft continuous
and soft closed mappings which are named as, ℊ-soft
continuous and ℊ-soft closed mappings. There are several
exciting results are gotten

The aim of this paper is to construct a new sequence of linear and positive operators which called Jain-Beta operators based on a parameter u,We investigated some properties of these operators when applied the approximation theorems. Moreover, we estimated the rate of convergence relying on concept the modulus of continuity. Finally,established a Voronoviskaja-type asymptotic formula

The main purpose of this research is to discuss the numerical solutions of a single-diode
nonlinear equation for a solar cell in a more efficient way. The inverse quadratic interpolation
technique for finding the root(s) of a function is applied to our study problem. Numerical
results show that the proposed three points iterative method is compatible to Newton's
method, accurate and effective.

In this work, we suggested a novel algorithm to computation
the optimal Solution for the fuzzy octagonal fractional
programming problems (FOFPP) were transformed to crisp
value (CV), through the ranking function (RF), and then solved
a crisp value by graphical method. Finally, numerical examples
are presented to display the efficacy of the computational
procedure.

In this paper, the influence of magnetohydrodynamic (MHD) on a mixed convective heat and mass
transfer analysis for the peristaltic transport of viscoplastic fluid in a non-uniform two dimensional
tapered asymmetric channel with porous medium is investigated. The governed equations that
described the motion of flow are simplified under assumptions of low Reynolds number and long
wavelength. These equations are solved by mean of the regular perturbation method which is restricted
to the smaller values of Bingham and Grashof numbers. Series solution for the axial velocity,
temperature and concentration distribution have been computed. The flow quantities have been
illustrated graphically for different interesting parameters. The trapping phenomena is also examined
graphically.

Recently, most of the web applications depend on the web services to solve the application integration problem. Web service is an intermediate software that allows the interaction between the applications written by different languages. Web Service is a client-server, modular, self-contained, and dynamic application that ensures the communication between the applications via the World Wide Web (WWW). The aim of this paper is to choice right kind of Web services at design stage of the project. Thus, we provide an overview of web services. Next, we clarify the architecture of web services. After that, we focus on the most popular kinds of web services, the Representational State Transfer (REST) and the Simple Object Access Protocol(SOAP) then explain APIs details. Finally, we address the performance evaluation of the previous works and explained the results as comparison between SOAP and REST. A recommendation to use RESTful web services has been concluded from experimental result.

The application of Response Surface Methodology (RSM) in the
biodegradation process can enhance removal, reduced process variability,
decrease development time and overall costs. In this study,
the non-linear response behavior was analyzed using the center points and star
points runs. The response was the biodegradation rate of pyrene; a 4-ring of
polycyclic aromatic hydrocarbon by fungi that
identified as Rhizoctonia zeae SOL3 in batch experiments. Factors like glucose
concentration, NaCl concentration, initial pyrene concentration, pH,
temperature and agitation were investigated to determine
the optimum parameters for the biodegradation rate of pyrene. The quadratic
model forecasted that the higher biodegradation of pyrene was 44.7% in 15
days, when the factors glucose concentration,
temperature, NaCl concentration and initial pyrene concentration were 19.6 g/l,
28°C, 9.9 g/l and 24 mg/l respectively. Validation experiment was made in
duplicate to verify the forecasted results. The
biodegradation was 44% in 15 days under the optimal medium conditions,
which was in good match with the forecasted values.

The use of the Residue Number System (RNS) instead of the known binary arithmetic
proposes, it is substantiated that the application of the non-position RNS will allow increasing
the speed and reducing power consumption of digital image processing applications.
Analyzed known schemes, based on which the process of image filtration occurs. The
inefficiency of the application of known schemes is substantiated, connected with the
possibility of errors due to the overflow of the dynamic range of the RNS. A new scheme of the
filtration transformation process is given, which allows obtaining correct results of digital
processing, independent of the size of the digital image being processed and the filter mask.
The obtained results can be used in the construction of specialized digital image processing
systems with low power consumption and high speed of operation
