Abstract:

The transport and retention of crude oil in sandy soil was studied. A full factorial experimental design with three independent variables, namely soil depth, contaminant volume and rainfall intensity, was used. The soil was artificially contaminated with varying crude oil volumes and rainfall simulation was performed in a mesocosm. The results obtained showed variations in the transport and retention of crude oil with the independent variables. The leached total petroleum hydrocarbons (TPH) concentrations decreased with increasing soil depth but increased with increasing contaminant volume and rainfall intensity. Contrarily, the retained TPH concentrations increased with increasing soil depth and contaminant volume but decreased with increasing rainfall intensity. Transport and retention models were developed and used to fit the transport and retention of crude oil in sandy soil after accidental release with correlation coefficient of 0.9407 and 0.9446 for the transport and retention model, respectively.

Abstract:

Cloud processing is turning into a conspicuous figuring worldview that enables clients to store their information into a cloud server to appreciate adaptable and on request benefits. In any case, cloud processing isn't trusted, and its security could be undermined by hacking and equipment mistakes. Thusly, in disdain of having focal points of versatility and adaptability, cloud capacity administration accompanies protection and security concerns. A clear technique to ensure the client's security is to encode the information put away at the cloud. The current gathering key administration instruments assume that the server is trusted. In any case, the cloud information administration does not constantly meet this condition. In any case, these plans are as yet not verify against the agreement information assault, what's more, disavowed bunch clients during client denial in a available distributed storage framework. In this framework, Users can accomplish a conservative and compelling methodology for information imparting......

Abstract:

The Routing and Wavelength Conversion are the two key techniques for improvement of the overall blocking performance in the wavelength routed all-optical networks. The Wavelength Converters are expensive, and thus the effective use of Wavelength Converters or more precisely the placement of minimum number of Wavelength Converter in appropriate nodes in the network is a challenge in the field of wavelength division multiplexing (WDM) optical networks. The performance of wavelength division multiplexing (WDM) network is highly dependent on Wavelength Converter allocation and routing problems. Typically treated as independent problems under dynamic traffic.

Abstract:

INCONEL (nickel-chromium-iron) alloy 600 is a standard engineering material for applications which require resistance to corrosion and heat. The alloy also has excellent mechanical properties and presents the desirable combination of high strength and good workability. The high nickel content gives the alloy resistance to corrosion by many organic and inorganic compounds and also makes it virtually immune to chloride-ion stress-corrosion cracking. Chromium confers resistance to sulfur compounds and also provides resistance to oxidizing conditions at high temperatures or in corrosive solutions. The alloy is not precipitation hard enable; it is hardened and strengthened only by cold work. The versatility of INCONEL alloy 600 has led to its use in a variety of applications involving temperatures from cryogenic to above 2000°F (1095°C). The alloy is.....

Abstract:

Blood oxygenation and heart rate detection based on infrared detection technology is one of the basic technologies of modern wearable devices and medical monitoring. In order to obtain fast and accurate blood oxygen and heart rate, this paper studies the algorithm for acquiring heart rate and blood oxygen. First, the pulse wave signal is collected based on hardware and software design. The pulse wave is then converted to a bipolar signal by a time domain method and a frequency domain method. The spectrum of the pulse wave is obtained by moving average filtering and fast Fourier transform. Finally, real-time heart rate and blood oxygen data are calculated based on the spectral waveform data. The experimental results show that the algorithm studied in this paper runs very well, and both methods can obtain actual heart rate and blood oxygen data.

Abstract:

Geopolymer is a new group of materials produced by the alkaline activation of alumino-silicate compounds. The interest of this project is to investigate the influences of synthesis parameters such as processing temperature, molarity of NaOH and ratio of Na2SiO3/NaOH on compressive strength of a geopolymer mortars. Geopolymer samples are prepared using varying concentrations of alkaline activators along with varying precursors such as silica fume, ground granulated blast furnace slag (GGBS) and fly ash. With sol/solid = 0.2 (as arbitrary), Na2SiO3/NaOH = 2.5 (as arbitrary) and NaOH molarity of 7M and 11M geopolymer samples are prepared and cured at different curing conditions. Compressive strength of these samples is found out and the optimum mix proportion is found out. Finally, an early strength development in geopolymer concrete could be achieved by the proper selection of curing temperature and the period of curing.

Abstract:

This paper introduces novel big data migration architecture with its data fundamentals description, processes and an interface related to big data migration. It describes a homogeneous novel framework for implementing the big data migration between relational databases and non-relational databases on the on-premise server using map reduce. The main goal of this big data migration framework is to migrate the massive data stored in relational database to NoSQL database parallelly with minimal downtime. Another objective is to increase the post-migration process after performing live migration. The proposed framework helps migration of big data from a relational database to a distributed platform quickly and easily.

Abstract:

Fly ash is used as fine granulates becomes suitable for partially obstructing voids in addition to pores .At later ages, the concrete mix which is replaced with fly ash exhibit greater strength development than control mix as the relative strength continues to increase with curing times. There is a significant reduction in comparative strength, with greater and consistent reduction at higher replacement levels of fly ash content. There is a important reduction in relative strength, with greater and consistent reduction at higher replacement levels of fly ash content. At later ages, the concrete mix replaced with fly ash leads to decrease in coulombs charge passed, due to higher amount of pozzolano and proper particle size distribution resulting in lower permeability. The permeability is an....

Abstract:

Payment plans are a key tactical area for success and growth of a knowledge based industry and also optimum salary offer is essential to retain high performance employees. One of the challenges that industries face very often is finding such income facts, based on several information about a current employee or a future employee. Given the characteristics of a current employee or a future employee like his / her demographic profile along with other information such as performance level, qualification, etc., prediction of the salary class can be done by using many well-known machine learning algorithms. But unluckily, those details of employee of any industry are generally not presented....
