Abstract
In growing era of cloud computing, one major utility is better and improved performance. For which Cloud Computing is a model which provides various resources available in a pool from where the users can get available the same when required. In the overall process there can be an important issue that is Fault tolerance to provide the high availability for the process which is being required by the user. And simultaneously if any fault occurs then user might not found any server downtime and other kind of delay in getting the response. There are many compute nodes such as Virtual machines further controlled by the Hypervisor. For transferring the load among compute nodes can be done by Cold Migration earlier there was a technique Non-Live migration. But at the same time there were lot many issues and challenges with the same that user might get the server downtime for infinite delay. For overcoming that there is an on-going technique which is known as Hot Migration or Live migration. It allows system administrators to shuffle the load available on an operating system instance to other Guest Operating system instance without any intervention on hosted service. This approach benefits to provide and efficient online system where no downfall in server maintenance. It also cures the load balancing, reconfiguration of data centers. The simulation of above aforesaid concept has been done via Cloudsim a tool for modelling and simulation in Cloud computing environment for live migration of virtual machines without intervention of cloud services. This paper simulated the work and gives the efficient results in comparison to the existing techniques.

Evaluating effects of various mineral admixtures when replaced with a part of cement in concrete
Authors: Sharma Ujjwal , Yadav Bhuvnesh , Gupta Nakul 
Published: May 2021

AbstractWith increase in the demand of concrete there is increase in demand of cement. Manufacturing cement leads to emission of harmful gases like carbon-di-oxide. This emission of harmful gases in environment led to global warming. On another hand increasing waste landfills of different materials such as brick-dust, ceramic-dust, husk-ash and many more leads to environmental pollution. Hence to save the environment from the harmful gases and also from increasing landfills we make use of various waste material termed as pozzolans. In the pre-requisite research we had taken three different pozzolans say china-clay, flue-ash and brick-kiln-powder. All the three pozzolans were replaced with the part of cement in concrete. The replacement was done to evaluate the pozzolans effect on concrete. The pozzolans are replaced in various set proportions. The replacement proportions were 3%, 6%, 9%, 12%, 15%, 18% and 21%. The concrete developed using various proportions of different pozzolans were tested for various test. The tests were done on fresh concrete and also after concrete get hardened. The tests conducted were C-S, S-T-T, and workability test. In total 189 cubes samples and 189 cylinder samples were casted. The investigation at last concluded that 12% of china clay, 21% of flue-ash and 18% of brick-kiln-powder separately when replaced with cement showed tremendous results as compared to normal concrete. Both C-S and S-T-S were seen to be increasing in same pattern. As the proportion of china-clay increases in concrete the value of slump tends to decrease. But in case of flue-ash it was increasing with increase in%replacement of flue-ash. The slump value in case of brick kiln powder assumed to be higher at 12% replacement. Hence, it was concluded that use of pozzolans in concrete in replacement to cement is good.

Abstract
Pozzolanic additives set off a fundamental part of high strength and most durable concrete mix design. Pozzolanic materials include natural products such as volcanic product (ashes and pumice) and by-product includes metakaolin, rice husk ash, silica fume, fly ash etc. Diatoms have been utilized as one of the pozzolanic additives in industrial sectors and construction industries to improve the rheological and mechanical properties of cement. Diatomite is sedimentary rocks comprised of amorphous or active silica as its main origin. It is being used very frequently as a pozzolanic additive in cement mortar and concrete. It has manifested appreciable effect in altering mechanical and chemical properties of cement. This paper gives an outlook of the work executed on application of diatomite as partial replacement for Portland cement in mortar and concrete. Different mechanical and rheological properties of cement and concrete containing raw diatomite have been widely discussed in the paper.

Abstract
Detection of digital change is the approach that helps to assess the changes associated with land use and land cover resources. Detection of landuse/landcover change in the form of maps and statistical data is very useful for land spatial planning, management and utilisation. In order to research land use / land cover shifts, Remote Sensing and Geographic Information System (GIS) were used. The goal of this study is to detect changes in land use between 1929 and 2009 using satellite images of 1990, 1999 and 2009 TM map data and 2009 Google Earth Imagery and topographic map surveys of India. The study developed a five-year (1929,1970,1999,2005,2009) land use/land cover map of the Korba district of Chhattisgarh to detect changes in the residential area, mining area, water bodies, farm lands, and forest areas in particular. The objective of study is to prepare land use/land cover map for different time periods, analyse the land use changes and evaluate the socio – economic implications of predicted change. Landuse changes have been detected by image processing method in ArcGIS9.3. Monitoring of landuse/landcover changes help to study impact of increase in industrialization on environment and to plan development activities and frame development policies. During this period of 80 years the forest area decreased nearly by half of that in 1929 from 4622.82km2 in 1929 to 2241.66km2 in 2009. The agriculture area increased during the period 1929 -1970 showing that deforested land was converted into agriculture land during this period from 1970 onwards mines and barren area increased from nil to 527.72 km2 in 2009. Residential area showed a drastic increase during the period 1970 -1999 due to migration of people from nearby areas to coal fields in search of livelihood.

Complexity Estimation for Distributed Software Development Using SRS
Authors: Apurva Agarwal 
Published: May 2021

Abstract
In recent years distributed software development has gathered pace. Many development programmes now require asynchronous coordination several time zones apart between geographically dispersed teams. Owing to considerations such as effort spent on team development and technology sharing, software complexity calculation for such projects is difficult to establish a software system infrastructure that can be efficiently spread and minimizes cross-site connectivity, enabling communication between remote teams working on interrelated sections of the architecture and their day-to-day interactions. A globally distributed software project faces, in addition to the technological complexity, an additional complexity contributed by the different supporting parameters. This paper defines these parameters and attempts to estimate all the complexities described above and incorporate these two measures to obtain the corresponding overall measure of complexity during the requirement analysis phase.

Published: May 2021

Abstract
The results of the experimental investigations of a ceramic circuit board sample with an embedded flat heat pipe are presented. The sample was made based on the technology of low temperature co-fired ceramic (LTCC). The flat heat pipe is formed at the bottom side of a ceramic substrate using a capillary structure made of sintered copper powder. The developed prototype of the LTCC module was used for the investigation of removing and spreading of high heat fluxes from high power electronic components mounted on the module. The embedded flat heat pipe filled with acetone provides 40 W/cm2 of heat flux removal from the heat source with the heat dissipation area of 1 cm2. The measured value of the thermal resistance between the heat source and cooler surface under the module is 0.8 °C/W.

Published: May 2021

Abstract
The aim of this work is to experimentally evaluate the heat exchange of evaporation and condensation inside a new annular thermosyphon with horizontally located zones of evaporation and condensation, which are interconnected by a vapor line and a condensate line. The mini-tube of the liquid line is introduced coaxially into the cylindrical evaporator with a porous coating, thus an annular channel is formed between the tube and the porous coating of the evaporator. The purpose of this study is to determine the thermal resistance of the device and its components, as well as the temperature field along the thermosyphon. The considered thermosyphon guarantees a shorter start-up time, lowers the temperature of the evaporator walls, has a small temperature hysteresis with an increase/decrease in the transferred heat flux, and suppresses temperature pulsations inside an evaporator. The 130 mm long evaporator is made of copper tube (d
out = 12 mm, d
in = 10 mm). The wick is obtained by sintering copper powder. The working fluids R245fa and R600 were used. The thermal resistance of thermosyphon does not exceed 0.5 K/W, and of the evaporator 0.1–0.05 K/W).
Interference Mitigation in the Wireless Communication Systems Using Adaptive Filters
Authors: Mohammed Jafar Ramadhan 
Published: May 2021

Abstract
In the current fifth generation (5G) wireless communication systems, the interference mitigation issue becomes a major and most important task for improving the performance of such systems due to corded spectrum and increased demands for new applications. Antenna arrays controlled by adaptive algorithms are proved to be a good solution for such problem. However, there are still some practical limitations in implementing such fully adaptive arrays especially when consisting a large number of the controllable elements. Other disadvantages of such arrays include long convergence time of the algorithm and the complexity of the beamforming network. In this paper, an adaptive algorithm is connected to only limited number of the array elements instead of all elements. We found that the elements that located on the center of the array could be chosen as adaptive, while the other elements which have less effect on the array pattern are left without adaptation process. Thus, the proposed array has many advantages with compared to those of the fully adaptive arrays while maintaining the same performance in suppressing the interference signals through null steering. Simulation results show that the effectiveness of the proposed array in generating deep nulls with very short convergence time.

Published: May 2021

Abstract
This paper presents a low-cost, compact, beam-steering phased array antenna (PAA) system based on a novel approach to integrating low-cost, high-performance phased shifters with their controlling boards within an antenna structure. Consequently, the system has been reduced to one structure for the antenna array and integrated phase shifters, rather than the sophisticated PAA with two separate boards which are connected by RF coaxial cables. The system has been achieved by the following stages; Firstly, the steering vector weights matrix was calculated by MATLAB. Then, four elements of uniform linear Microstrip patch antenna array with their feeding network power divider were designed and simulated in the CST simulation program. As a result, a practical model has been implemented. The designed RF-PCB for the 4-bit phase shifters MAPS_010143 were integrated within the antenna panel. The system works at a resonance frequency of (2.4 GHz), with (±45°) steering capability. The results are presented for the three models. The practical results match the simulation results very closely, fence proving the accuracy of the model and demonstrating a highly effective design.

Published: May 2021

Abstract
The present work will focus on the investigation of the influence of defects density and carriers capture cross-section are in absorption layer on the performance of perovskite solar cells. Furthermore, the impact of defect density in the electron transport material ETM/absorber interface layer will also be studied. The hybrid halide perovskite solar cells are chosen in this work and will be simulated by using one-dimension solar cells capacitance simulation SCAPS-1D. The proposed structure of the perovskite solar cell is a planar FTO/ETM/perovskite/HTM based on TiO2
and Spiro-OMeTAD as electron transport layer ETM and hole transport layer HTM, respectively, and on CH 3NH 3PbI 3
as absorber layer (perovskite). The results showed that when the defect density in the absorber layer was varied from 10 10cm -3 to 10 18 cm -3, the cell parameters, open circuit voltage (V
oc), the short circuit current (J sc
), the fill factor (FF), and the efficiency (PCE)were significantly decreased. At high defect density (10 18 cm -3), the defect affects negatively on the cell performance due to the high recombination rate of Shockley Read Hall. Similarly, the capture cross section exhibits similar behaviour in the active layer. By increasing the defect density in the ETM/absorber interface layer, the main cell parameters PCE, FF, and J sc
are slightly reduced and there has been no noticeable impact on V oc
.
