Authors: Rusdiana R , Nurhasan  , Viridi S , Fitriani D 
Published: October 2021

Abstract
Landslides are the third-largest natural disaster and have resulted in many victims, both property and casualties. One area where landslides occurred with casualties and heavily damaged houses was in Jayagiri, Lembang, West Java, Indonesia.
One essential parameter in researching landslide-prone areas is the sliding area, where rocks or soil above the plane can move, resulting in landslides. Research on landslides continues to be developed from various fields of science. This study uses the Geoelectric method to determine and analyze the sliding area carried out in the Jayagiri area, Lembang. A reasonably significant resistivity value characterizes this field compared to the surrounding rocks. The measurement result on three lines shows that the study area is divided into two parts: the dominance of high resistivity and low resistivity. 2D inversion modeling shows that the slip plane has a resistivity value of 500 ohms.m at a depth between 9 m at the top of the slope and 13 meters at the bottom of the slope. The existence of a relatively shallow sliding field indicates a depth of water infiltration with a resistivity value of 10 Ohm.m, which is shallow enough so that it can be assumed that this area has the potential for landslides.

Published: October 2021

Abstract
In order to expand a new millimeter wave absorbing material over the V-band frequency range, teflon were prepared with thickness of 1.4 mm, 1.5 mm, and 1.6 mm. The variation of electromagnetic variables (complex permeability µ=µ′–jµ″ and complex permittivity ε=ε′–jε″) properties were studied over the V-band frequency range with varying sample thickness. Both dielectric loss (ε″) and magnetic loss (µ″) were leading to strong fluctuations, whereas the dielectric constant (ε′) was found to decrease and magnetic permeability (µ′) increased in the frequency range of 50–67 GHz.

We also extend this possibility to bi-coherent states, and we discuss in many details an example based on a couple of superpotentials first introduced in [30]. The results deduced here belong to the same distributional approach to pseudo-bosons first proposed in [29].

Authors: Bagchi Bijan , Vinod Achal 
Published: October 2021

Abstract
We extend Fring-Tenney approach of constructing invariants of constant mass time-dependent system to the case of a time-dependent mass particle. From a coupled set of equations described in terms of guiding parameter functions, we track down a modified Ermakov-Pinney equation involving a time-dependent mass function. As a concrete example we focus on an exponential choice of the mass function.

Published: October 2021

Abstract
Identification of Node failure detection and a localization is a very important challenge in a network community to get a quick recovery and avoid useless traffic in network. But it is very difficult to check the failure nodes or locations because of the large number of Screw ups in dense network. As finding the main source for failure of network is always challenging our proposed work will achieve that, it identifies the node failure by using probing measurement of binary state to end to end paths. Apart from identifying the network failure, it also quantifies the total failure nodes and the ip address or vicinity of failure nodes, Identification of node failure is done by monitoring nodes which are deployed in the netwok. Our Proposed word is divided majorly in two phases one is identifying the node failures by using Probing Packets and other is finding of the failure and its recovery.

Authors: Grace Mercy M. , Kamala Kumari A. , Bhujangarao A. , Nooka Raju V. 
Published: October 2021

Abstract
The geometry of the GPS satellite recipient (s), which reflects the recipient (s) of the satellites, has a major influence on the total positioning precision. The more precise the position, the stronger the geometry of the satellite. This article provides the geometry of satellite clustering for the selection of suitable satellite navigation subsets. This technique is based on the GDOP (Geometric Precision Dilution) satellite factor cluster with the Ant Colony Optimization (ACO) algorithm that has been created by simulating real and artificial ways to locate the quickest route between nesting resources and food. Pheromones are utilised in the suggested technique to assess the iterative outcome of single colonies. The ACO method can measure all subsets of satellites while reducing computer load by eliminating the need for a matrix inversion. Based on the simulation results, the GPS GDOP clustering technique is more efficient at achieving its optimum value.

Abstract
One major source of water on the Earth is Surface water resources such as Rivers, Rain water sewers, Streams etc. With the rapid change in the mode of usage of land for various purposes like residential, agricultural, industrial, water storage basins, the volume of Surface runoff due to Rain & melting of Snow changes. Estimating such quantities of runoff is essential for proper managing of Water resources over the Earth surface. Runoff estimation of each Mini Water has been done by SCS-CN Curve number method. The required data for this method include Land Use/Land Cover trends of past years, Hydrological Soil Groups, Rainfall trends and AMC Type. Based on the analysis a considerable change in the Groundwater Recharge in the study area is found due to the variations in the Built-up & vegetative cover features ultimately resulting in increasing Surface Runoff there by excess inflow may enter into the Megadrigadda reservoir resulting in Flash floods during monsoons. In the coming years there are chances of the Dam being breached thereby affecting the Visakhapatnam Airport area in its Downstream.

Published: October 2021

AbstractThis article discusses the behavior of a reinforced concrete deep beam that has been strengthened with GFRP sheets. The GFRP shows many essential and necessary properties such as low weight to strength ratio, non-corrosive, high fatigue strength, high tensile strength, etc. In this paper, four deep beams were cast, in which one beam is a control beam, and another one is with special confinement reinforcement. The rest of the two beams are strengthened with the GFRP sheets in standard control beam and special confinement reinforcement beam under static or monotonic loading under three points, and the corresponding behavior is determined. The behavior of the RC Deep beams, such as load-carrying capacity, first crack load, load-deflection behavior, crack patterns, and stress vs. strains, are determined. The analysis of the reinforced concrete deep beams was done using the finite element software called ANSYS. Additionally, this article provides preliminary support for proposing a novel shear strengthening technique during the member’s design. In the finite element simulations, the proposed deep beams have been modeled and analyzed using the finite element software, ANSYS, and the results are compared with experimental work.

Published: October 2021

AbstractFinite element method is a precise and flexible technology for predicting the performance, load conditions of a structure, mechanism or process. During the tests, the structural behaviour was used to build a FEM, especially for the nonlinear analysis. As the failure approaches, angles under tension exhibit non-linear behaviour. Everything is constructed, including the static structural component and all of its modules. Like ANSYS MAPDL modules (Mechanical Ansys Parametric Design Language). Build geometry, define materials, generate mesh, apply load, solving the model, and reviewing the results are all part of the static analyses of FEA. In order to determine the various structural investigations of a single or double section, a number of models have been developed. There were 72 specimens used in the analysis; they were modelled by bolt tensioners that were attached to the specimen. In order to calculate equivalent stress, equivalent elastic strain, and total deformation of single angle and double angle sections, equivalent stress, elastic strain, and total deformation of single angle and double angle sections were examined. In order to find out the ultimate load-carrying capacity of the single angle specimens and double angle specimens, a non-linear static analysis was done. The findings from the experiments, computational codes, and worldwide investigations into load capacity tension members are detailed in the paper. Failure modes are observed, too. In an ANSYS simulation using a numerical model, which used the ANSYS angle algorithm, researchers discovered that experimental and international codes values closely match each other.

Authors: Samuvel Michael B , Muthurajan K.G. , Samuvel Michael B. 
Published: October 2021

Abstract
Recycling is the retrieval, reclamation, reprocessing or refining process of waste to produce new products. Recycling has always been a top priority in waste management since it enables us not only to maintain the health of the environment, but also to reuse garbage profitably. Many techniques are utilised to transform plastic waste into articles that are not present in virgin plastic with distinctive features. Polymers undergo molecular and structural changes in this process leading to simpler basic materials with superior thermal properties than original plastics. While gasification and pyrolysis processes break plastics down, fluid and semi-liquid products are also generated.

Authors: Vega-Posada Carlos A. , Garcia-Aristizabal Edwin F. , Saldarriaga-Molina Julio C. 
Published: October 2021

Abstract
This paper presents a simplified method to examine the response of circular tapered Euler-Bernoulli beam-columns. The Di˙erential Transformation Method (DTM) is implemented to solve the di˙erential equation (DE) that governs the response of the element. When conventional analytical approaches (i.e., discrete or continuum approaches) are used to solve the DE, and because of the introduction of the non-uniform cross-section and the soil non-homogeneity, the analysis becomes rather di˚cult and the solution complex to obtain. Here, the rather complex DE and corresponding boundary conditions (B.Cs.) are expressed as a system of linear algebraic expressions which solution is readily available. The proposed formulation includes the e˙ects of i) semi-rigid connections and lateral restraints at the ends of the element, ii) an external transverse load, iii) flexible and short elements, iv) soil/element sti˙ness, and v) an elastic homogeneous or non-homogeneous Pasternak soil. Both static and buckling analysis can be carried out using the same formulation.

Cellulose in natural flocculant applications: A review
Authors: Fauzani D , Notodarmojo S , Handajani M , Helmy Q , Kardiansyah T 
Published: October 2021

Abstract
Natural polymeric flocculants have gained popularity in water and wastewater treatment in recent years due to their non-toxicity and biodegradability. Because of its broad availability, renewability, sustainability, and surface modification potential, cellulose is regarded as one of the foundation polymers for flocculant production and modification. The following literature review includes of an overview of coagulation-flocculation, which is the process mechanism consisting of colloid destabilization for coagulation, followed by bridging, charge neutralization, and electrostatic patch for flocculation; aspects affecting the coagulation-flocculation performance; as well as the types of coagulants and flocculants that are commonly used. Furthermore, we will go over the physical and chemical properties of flocculants, as well as their usage as a coagulant-aid in the flocculation process following coagulation and as a flocculant in direct flocculation. There is also a discussion of the most recent advances in biopolymers, which are natural materials used to alter biopolymers as flocculants such as chitosan, tannins, starch, and cellulose. Whereas there is a review of the cellulose modifications that have been performed in past research to make it a natural flocculant, the use of ramie cellulose as flocculants has never been carried out to be used as a coagulant-aid and/or flocculant in drinking water and wastewater treatment. Ramie cellulose as backbone of biomaterial composites are expected to be applied as flocculants, have good flocculation performance, and can facilitate sludge handling in water treatment plants and/or wastewater treatment plants.

The plasma in all models at a distance of 1.2 mm (narrow gap) are shown that the highest light intensity in model 1, while the lowest light intensity in model 4. The light intensity in model 1 are also higher than model 2 and 3, respectively. There are many current pulse or noises for model 1 and 2. However, there is a bit of current pulse in model 3 and 4. It is indicated that there are any micro discharges in the gap. Furthermore, the effect of intensity of magnetic field is influence the micro discharges in the gap. The DBD in model 1 produces maximum voltage and current of 8 kV and 37 mA, respectively. Model 2 is at 8.1 kV and 36 mA for maximum voltage and current, respectively. Finally, the model 4 adjusts the maximum current and voltage of 8.12 kV and 36 mA, respectively. It is indicated that the intensity of magnetic field influences the maximum voltage of DBD. Then, it is also shown that the maximum currents of DBD has varied. It is indicated that the intensity of magnetic field and attractive and repulsive conditions of magnet has also influenced the ozone production for all models. Model 3 of DBD produces higher ozone concentration than model 1,2 and 4, respectively.

Lead is a heavy metal that can adversely affects all organisms in the waters and can accumulate in the food chain, it is harmful to human and animal if exposed to it. Adsorption is one of the technologies for separating dissolved metal ions in liquid that easy handling and very effective. The concentration of heavy metal ions in solution can be reduced by using a adsorbent, such as zeolte, activated charcoal, regenerated spent bleaching earth (RSBE). Spent bleaching earth (SBE) is a disposal from edible of the bleaching unit in oil refinery industries, it can be regenerated to a adsorbent RSBE. The treatment SBE into RSBE, oil of SBE is separated by the solvent extraction method at 72°C for 5 hours with n-hexane as a solvent, followed by washing it with HCl 3%, then physically activated at 470°C for 12 hours.
