Big Data advances in three key areas like storage, processing and analysis. Hadoop architecture is produced to store extensive measure of data through adaptable parallel handling with speed to get the outcomes. Organizations must guarantee that every single big data bases are resistant to security dangers and vulnerabilities. Amid data gathering, all the important security assurances, for example, continuous administration should to be satisfied. Remembering the big size of big data, Organizations should to recollect the way that overseeing such data could be troublesome and requires uncommon endeavors. Be that as it may, making every one of these strides would help keep up buyer protection. The Security and Privacy challenges for Big Data might be sorted out on big data community. Securing the framework of big data frameworks includes Securing appropriated calculations and data stores. Securing the data it is of vital significance, so we need to guarantee that data scattering is security saving and that touchy data is ensured using cryptography and granular access control. Overseeing tremendous volumes of data requires adaptable and conveyed answers for Securing data stores as well as empowering effective reviews and examinations of data provenance. At long last, the streaming data that is rolling in from various endpoints must be checked for respectability and can be utilized to perform continuous examination for security episodes to guarantee the strength of the framework. The explanation behind such ruptures may likewise be that security applications that are intended to store certain measures of data can't the huge volumes of data that the previously mentioned datasets have. Likewise, these security advances are wasteful to oversee dynamic data and can control static data as it were. In this way, only a customary security check can't distinguish security patches for nonstop streaming data. For this reason, we require full-time protection while data streaming and Big Data Analysis.Â Â

Published: July 2024

In this abstract, we investigate a noble low power VLSI logic design technique by applied substrate bias to MOSFET & control threshold voltage (VTH) of MOSFET deviceÂ  i.e. dynamic threshold MOS (DTMOS) logic design for combinational digital logic gates. DTCMOS logic design has larger driving ability with low leakage current ( i.e. low power dissipation) as compare toÂ  ratio-less static CMOS logic design. DTMOS approach that takes advantage of partially-depleted SOI technology, by providing an fitting substrate bias that varies according to gate voltage(VG), As we know thatÂ  the VTH of the device is depending on its VG (i.e.by vary gate voltage we control the VTH of MOSFET). Under above circumstances, an improvement in delay while using less power than conventional transistors can be achieved. The behavioural comparison of DTMOS & CMOS logic design circuit are funded with respect to parameters such as Power dissipation, Propagation delay & Figure of merit evaluated through circuit simulator CAD tool HSPICE.Â Â

Published: July 2024

An examination on costly classifiers impacting essential choices utilizing expectations is a vital research field for the information mining analysts. Notwithstanding, the determination of parameters for such classifiers assumes an imperative job in getting more exactness and less expense in the basic setting. Following this rule, a measurement dependent on a levelheaded number, dictated by the proportion between the quantities of false positives to false negatives in assessing the classifiers is considered. Cost delicate models too the cost dazzle models are normally both acknowledged by their execution through least blunder or most extreme exactness. Thus in setting of understudies points of interest from East London locale and from Yorkshire district should be connected with more significant measures to locate the correct minimal effort esteems. In this paper, we analyze the cost touchy classifiers and measure their execution by shifting the parameter (False Positive and False Negative). We recognize distinctive examples of conduct of these classifiers for various scope of qualities. Add up to cost for four unique reaches are investigated independently and the exhibitions in the two-distinctive setting of understudy detail from East London district and from Yorkshire locale are considered. Add up to cost of understudy subtle elements from East London area happens to be more than expense of Yorkshire district while tuning the parameters. These discoveries can bolster the choices of diagnosing which methods for instruction is more important to choose with foruming or non-foruming with more certainty.Â Â

Published: July 2024

The role of a non-conventional yeast, Kluyveromyces marxianus in the bioprocessing industry has shown potential as metabolites producer, making it a suitable candidate for replacing the bakerâ€™s yeast for various industrial applications. The mathematical approach is used to analyze the flow of metabolites in the biological system in order to improve the desired product yield as well as the overall production process. Thus, the development of a simple model could lead to sustainability and practicability of the process. In this study, the comparative analysis of a simple metabolic network and a black box description is carried out in order to evaluate the growth and bioethanol production in K. marxianus batch culture. Metabolic flux balance methodology has shown to give a more accurate estimation with the complete analysis of the reaction rates. Furthermore, better evaluation of yeast behavior and performance in a batch system at varying glucose concentrations were achieved based on its stoichiometric reaction analysis. At the highest substrate concentration used, biomass growth was maximum at 12.32 g/l, with 7.75 g/L ethanol obtained. The biomass and bioethanol productions were mostly dependent on oxidative and reductive catabolism, respectively, in which the glucose and oxygen uptake rates played the main role in the regulation of the central metabolic networks. Therefore, biomass and ethanol production are strongly reliant on the cellular functionality of yeast in the culture, which shows the superiority of this method over the black box approach.Â

Published: July 2024

The design of a microbubble generator that has high efficiency and good performance is still a challenge today, especially for a large scale application. In this study, CFD simulation based on the transient operation was used to predict the characteristics of a fluid flow as a reference in the design process. To analyze the performance of the swirl flow microbubble generator, particle image velocimetry (PIV) was used to characterize the dimension and distribution of microbubbles. Based on the simulation results, CFD was able to visualize the mixing process and the fluid characteristics of the gas-liquid flow in a swirl flow microbubble generator. Air self-suction mechanism in a microbubble generator nozzle was successfully formed by a negative pressure in the central axis area of the nozzle due to a swirl flow of water. It shows that a swirl flow microbubble generator can work efficiently and doesnâ€™t need any other devices to deliver air into the system. Based on the PIV measurement, the microbubbles were successfully formed with the radius averaged of 25 Âµm for both air mass flow rate of 0.25 l/min and 1 l/min. However, the smaller the mass flow rate of air, the more the number of microbubbles generated.Â Â Â

Published: July 2024

Finite element analysis (FEA) is extensively used in the engineering field, especially in structural engineering. FEA is a numerical method used for solving engineering problems that involve complicated geometries, various loading conditions and material properties. A fatigue life assessment of an engineering component is necessary to predict the life span of this component before failure. Automobile alloy wheel is an engineering component that is exposed to fatigue failure in services. Therefore, this study aims to determine the critical area for crack initiation on automobile alloy wheel and to simulate and analyse the fatigue life of an automobile alloy wheel design that is fabricated from different types of materials. The automobile alloy wheel design was modelled using computer-aided design and analysed using commercial finite element software. The automobile alloy wheel was modelled based on a 1200 cc national automobile. Three types of materials, namely, titanium, aluminium and magnesium alloys, were used in this study. A critical part of a steering knuckle could be identified by conducting a stress analysis, and the fatigue life of the automobile alloy wheel could be predicted on the basis of applied loads. Results showed that fatigue life is significantly influenced by the types of material used in a simulation.Â Â

Gross Domestic Product (GDP) has been known as multi criteria measurement of market value from goods and services across nation. Even there has been an improvement study on accuracy recently, this subject still opens a huge potential of future research and method development and implementation. At this study, we compared a new approach on Moving Average method called Weighted Exponentially Moving Average (WEMA) that created in 2014. We implement the method on Phatsa Web Application and evaluate the results by calculating its Mean Squared Error (MSE), Mean Absolute Scaled Error (MASE), and Mean Absolute Percentage Error (MAPE). Comparison study with the conventional moving average methods named Simple Moving Average (SMA), Weighted Moving Average (WMA) and Exponentially Moving Average then conducted to review the capability of WEMA in predicting Indonesiaâ€™s GDP data. It is proven that WEMA can provide more accurate results rather than SMA and WMA, but it still has the same error rate value if compared to EMA with more computation time. In addition to the result, Czechâ€™s GDP data set is also tested and provides more information on how WEMA calculation with expanded data set, and more volatile value compared to Indonesiaâ€™s GDP in Czechâ€™s GDP data set.Â Â Â

Pneumonia is an acute infection that affects the lung tissue (alveoli) which can be caused by various microorganisms such as viruses, fungi, and bacteria. Pneumonia was the second leading cause of death (13.2%) after diarrhea (17.2%) among under-fives. It shows that pneumonia is a disease that becomes a public health problem that contributes to the high mortality rate of children under five in Indonesia.Â  In recent years, Bojonegoro city gives a large contribution for toddler pneumonia under five years of age in East Java district, Indonesia.Â  In 2012, pneumonia sufferers reached 90.17% of the total number of the toddler and still many the next years.Â  There are five risk factors for pneumonia include the number of children under five, the estimated number of patients, the number of sufferers, environmental factors and nutritional status.Â  A spatial approach is needed to see the spreading of pneumonia vulnerability level in each sub-district in Bojonegoro.Â  This approach can be used by the government as a supporting effort in controlling and preventing pneumonia which is more focused, efficient, and effective.Â  This paper proposes a new approach to generate a vulnerability mapping of toddler pneumonia using hybrid genetic algorithm - K-means (GA-Kmeans) clustering algorithm according to five risk factors.Â  K-means is a clustering algorithm that can produce data groupings based on several attributes well and quickly.Â  However, there is a problem in the initialization stage of the initial random seeds from K-means, which is very difficult to reach an optimum global.Â  The genetic algorithm is used to optimize initial seeds in the K-means algorithm. The vulnerability level of toddler pneumonia is classified into low, medium and high, then it is visualized into spatial mapping.Â  The result of GA-Kmeans test iteration experiments produced best variance cluster 0.99 (almost 1) and determined high levels of vulnerability in 2016 are Kedungadem, Kepohbaru, Baureno, Kanor, Sumberrejo, Balen, Kapas, Bojonegoro, Dander and Ngasem sub-districts.Â Â

Published: July 2024

As one of additive manufacturing (AM) technologies, selective laser melting (SLM) which uses higher energy input enabling fully molten powder bed materials is nowadays increasingly applied to build full dense components without post processing. In the present work, specimens made of stainless steel powder SS 316L were to be processed using SLM 280 HL, characterized and compared to commercial rolled sheet product with similar material and shape. The powders have been melted to form dog-bone specimen with two build up orientation using fixed major process parameters such as laser power, hatching distance and layer thickness as well as scan speed. The characterization starts with the mechanical properties and followed by microstructural analysis. While tensile strength and elongation were the main concern on mechanical properties to be discussed based on rolling and layer direction, the macro and micro analysis will focus on grain structure and fracture surface as well as the process quality. The material characterization was conducted using tensile test, optical microscopy and scanning electron microscopy. It is found out that the built-up direction, inclination angle and process quality play a big role on ductility and distortion using SLM. Although the rolled specimen showed significant difference of material strength compared to AM, the rolling direction however does not give conclusive results which can be referred to. It is expected that this basic characterization study will provide basic information and estimation towards the strength of material and final quality product prior to commencement of real product manufacturing.Â

Published: July 2024

Fingerprint verification has drawn a lot of attention to its approach in biometric since it is one of the most important biometric technologies nowadays and is widely used in several different applications and areas. It is applied in the forensic science area in order to identify people who were involved in criminal scenes such as the victims and the suspects. A humanâ€™s fingerprint is unique and usually has its own patterns and ridges, which differs them from otherâ€™s fingerprints. However, there are some drawbacks that can cause low accuracy and low performance of the verification. This occurs when the fingerprint images used are of low-quality and the fingerprints may be slightly incomplete (partial). Clonal Selection Algorithm (CSA) is known to be good in pattern matching and optimization of problems. Hence, this paper discusses the finding of the implementation of CSA in fingerprint verification. There were two main processes involved, which are features extraction using minutiae-based method and also the implementation of the CSA algorithm. Study shows that the FNMR result is 33.33% and the FMR is 16.67%. Further studies can be carried out by using the same algorithm, but focusing more on the feature extraction methods to improve the extraction of fingerprints.Â Â

Published: July 2024

The aim of this study is to study the effects of different types of extender and to determine the effects of cryopreservation process (before chilling, after chilling, after cryopreservation) on sperm characteristics and sperm morphology of Mafriwal bulls. Three natural based extender (Aloe vera based extender (AVBX), honey based extender (HBX), egg yolk based extender (EYBX)) and a control (BioxcellÂ®) were used as extender and compared for different semen quality parameters that can be assessed under routine laboratory condition. Semen samples were collected from three sexually matured Mafriwal bulls by using artificial vagina (AV). Samples collected were subjected to four different treatments and was evaluated after dilution with extenders. After diluted, the samples were chilled for 2 hours in 4Â°C. The semen samples were then packed into 0.25 ml straw for further cryopreservation process. After 24 hours, the cryopreserved semen samples were evaluated. Eosin nigrosin smearing were done to evaluate sperm morphology. The EYBX resulted in the highest percentage of almost all parameters tested in the study followed by BioxcellÂ®, AVBX and HBX. Semen treated with EYBX and BioxcellÂ® shows no significant different (P>0.05). All treatment shows decrease of sperm characteristics after chilling and frozen-thawed but AVBX and HBX shows rapid depletion of sperm characteristics (P<0.05) after chilling process. This study suggests that EYBX is the most suitable extender for cryopreservation Mafriwal bullâ€™s semen. However, further study is warranted to investigate the optimum concentration of other raw materials (i.e. Aloe vera and honey) in extender for semen cryopreservation.Â

Some wild edible vegetables are rarely been studied albeit freshly consumed by local people as â€˜ulamâ€™. Due to their perishable nature, drying is applied to extend their shelf life which causes substantial changes in phytochemicals content. Hence for collection of optimum yield of phenolics, the use of solvents of different polarities is crucial. In this study, the effect of drying (freeze-drying and oven-drying) and extractants solvents (ethanol and water) methods on phenolics and flavonoids contents as well as antioxidant activity of ten immature wild edible vegetables extracts (Acrosticum aureum, Erechtites hieraciifolia, Erechtites valerianifolia, Gnetum gnemon, Manihot esculenta, Oroxylum indicum, Phyllanthus acidus, Piper sarmentosum, Terminalia catappa and Ziziphus mauritiana) collected in Terengganu, Malaysia were investigated. Extraction were carried out using ultrasonication-assisted method. The results indicated that some vegetables were good sources of antioxidants with the lowest IC50 value of DPPH scavenging was 6.19 Î¼g/mL. Ethanolic freeze dried (EFD) extracts (0.5 mg/mL) showed stronger DPPH scavenging activity (Inhibition rates: 76 to 88%) compared to ethanolic oven dried (EOD) (56 to 88%) and aqueous freeze dried (AFD) (35 to 89%). Total phenolics content (TPC) and total flavonoid contents (TFC) were found to exhibit strong to moderate correlations with antiradical power. Among all samples, T. catappa following EFD, EOD and AFD showed the strongest antioxidant potential. The findings revealed that different drying methods and extracting solvents did influence the biochemicals isolation and antioxidant activity.Â Â Â

Chocolate is a cocoa based product derived from cocoa beans the seed of Theobroma cocoa tree. Nowadays, the demand of natural Â Â sweetener for manufacturing of sugar-free chocolate has dramatically increased. However, their applicability in product formulation and how it affects the quality of chocolate still remain a big challenge. Despite providing sweet taste in chocolate, bioactive compounds present in stevia leaves, palm sugar and honey could enhance human health. The effects of Stevia leaves powder, palm sugar and honey on the melting characteristic and crystallization of the milk chocolate were measured using differential scanning calorimeter (DSC). The melting peak of all those sweeteners are in the range of 37-38 â„ƒ indicating the presence of form VI polymorphs. However, the Â presence of multiple peaks was also observed showing that there was a competition between the growth of low and high stability polymorphs. Besides, only the substitution of sugar with honey produced a significant change in the enthalpy value (p<0.05). From the results obtained, Â it can be concluded that stevia leaves powder, palm sugar and honey could be used for sugar free chocolate.Â Â

In this work series of field experiments was conducted, a mathematical model was developed and a number of studies were performed to investigate the process of hydrate dissociation under the influence of ultrahigh-frequency radiation. The assumption is implicit that the effect of volumetric sources of heat is the dominant influence on hydration dissociation under the influence of microwave radiation, rather than the effect of boundary conditions. This provision formed the basis of the mathematical modeling of the hydrate massif dissociation. It has been established that processes of heating water, ice melting and snow, and hydrate dissociation occur in a similar way. It is characteristic that the inverse proportional dependence of internal specific heat sources on the volume of material has been obtained, that is, the decrease of the radiator efficiency when the volume of the material is reduced. It is established that volumetric thermal sources occur inside propane hydrate under the influence of microwave radiation.Â

In the article, based on the analysis of modern trends in the development of construction in the world shown, that the problem of increasing the competitiveness and efficiency of building steel structures is relevant. Conducted research of steel combined structures confirmed, one of the effective methods for solving this problem is the use of a calculated method for regulating the stress deformation state (SDS) in steel metal structures during the design process. It does not require any additional material costs and allows you to design equally stressed structures as the most rational systems. The results of experimental research of a metal-wooden truss12 m spans with the calculated SDS regulation during the design process are presented. Experiment results data, reflecting the real work of a metal-wooden truss, satisfactorily agree with the theoretical. Experimental studies confirmed the hypothesis of the possibility of regulating the stress deformation state of combined structures with elastic-supportive supports and the achievement of an stress equality state in the calculated sections. A numerical experiment was conducted for a combined steel sprengel truss with a span of18 m. Rationalized, in terms of material costs, height of a sprengel truss, the angles of inclination of the compressed rods of the grating of the truss and the strength of the reinforcement system. Examples of implementation of such rational structures are given.Â Â

The methodological principles of land relations and land assessment institutionalization have been substantiated and presented in this article. The authors have also gave grounds for the ways of solving the problems of objective definition of the absolute rent assessment mechanism taking into account the peculiarities of modern land use.There have been considered various options of assessing the possible receipt of the absolute rental value, which took into account cereal crops and where there were selected the most important crop plants in the crop structure of Poltava region.The article defines two basic methods of calculating the normative monetary evaluation of land, which are legally constituted and are in force today. But the problem is that they duplicate each other without specifying the mechanism for establishing absolute rental income on agricultural lands.In the article there have been considered different variants of assessing the possible receipt of the absolute rental value and organization of ecologically and economically efficient changes in sowing. The authors have also introduced the formation model of the social value of establishing prices for agricultural products.As a result, the received absolute rent reflects the formation mechanism of the surplus value above the rate of profit.Â Â

The purpose of the research is to manage the innovative activity of human resources. In order to achieve this goal, the procedure and components of such an analysis were determined. The directions of research of state of management of innovative activity of human resources are established. These include: analysis of human resources, analysis of conditions that ensure the implementation of such management and analysis of the economic efficiency of the enterprise. The factors influencing each of these directions of estimation of the state of management of innovative activity of human resources are grounded and systematized. Investigating the manifestation of these factors provides an opportunity to objectively assess how human resources management is effective and consistent with the innovative development of the enterprise. This approach also allows comparing best practices in human resource management. The definition of factors serves as the basis for forming an approach to a comprehensive assessment of the state of innovation activity management of human resources. The methodology for assessing the state of management of human resource innovation activity on the basis of rating is a new tool in this area. In addition, unlike existing assessments, it combines management, production and management of human resources. It was emphasized that human resources are the main factor of innovation development of the enterprise. The step-by-step procedure for assessing the state of innovation activity management of human resources is presented. The scale for analysis of the obtained evaluation results is proposed. It is noted that there is a need for further detailing the results to determine measures to improve the situation for a particular company. Approbation of the methodology of such an assessment of the state of innovation activity management of human resources for the seaports of the Black Sea-Azov basin was conducted.Â Â Â
