Decision Support System Using Mobile Applications in the Provision of Day to Day Information about Farm Status to Improve Crop Yield
Agricultural sector is a viable option in the diversification of Nigeria’s economy due to its large contribution of over 40% of the Gross Domestic Product (GDP) and it employment of about 60% of the working population. The sector is current faced with a decline in youth participation in Agriculture as well as poor crop yield of 1.8tons per hectare when compared to other country such as Egypt with 9.64 tons per hectare. The study identifies the use of information technology as a solution to these problems based on the large success rate in social media amongst youth population of the country. The study review various information technology farming tools which are capable of improving crop yield and increasing youth interest is agriculture. Finally, the study described the process of developing a rice farm decision support system to help rice farmers improve their yield
Alleviation of Void and Energy hole in Mobile cloud offloading using hybrid behavioral intelligence
In modern internet the usability of smart mobile devices is rapidly increased. It is not only used for commercial and communication purposes, it can be extended in the field like mobile health care, mobile learning, and mobile games. More access of smart mobile devices has a restriction due to resource constraint, this issue overwhelming via cloud computing. Heavy computations from mobile devices are offloaded to cloud and the application got executed. The problem occurs when the Electrogram data is entered into a mobile network in cloud environment which holds void and energy holes occurrences with heavy traffic and unbalanced load distribution.This paper aims to develop hybrid intelligence behavioural patterns for void and energy hole in mobile cloud offloading. The research work carried out in this paper extends its novelty in stage partitioning for concentric circles and sensor node distribution. The network area distribution of partitioning are uniformly distributed among void hole. The simulation results show the proposed approach produces high energy consumption in the mobile cloud paradigm
A numerical modeling of a profile velocity and Shear stress in transient flow applied in industrial technology
This research is devoted to theoretical and numerical models of transient shear stress in a transient laminar flow over the pipe wall. This work is an elementary method of the model Prado et al, which the base is on the expansion of velocity profiles ofthe flow in polynomial series of a radial space at acroass the right section of pipe. The set equations is derived from mass and momentum conservation laws. The system partial derivatives equations obtained is hyperbolique and suitable by the method of characteristics. This model is approved with the experimental results of Holmboe et al, and, Vardy et al. This digital code can be possible to join it in any tools, to simulateand to controle water hammer in pipe
Study of changing statistics model’s influence on the exploitation and conformity of results in the new standard version ISO 14644 part 1.
Recently, the first two parts of the standard ISO 14644-1 and 2 were updated. This followed a 9-year process of revision. The standard is applicable across several industries covering healthcare, pharmaceuticals and electronics; and it outlines the approach for the design, classification and operation of cleanrooms. This article assesses the influence of the changing ISO 14644-1 on the conformity of the results. The initial version of Part 1 was based on the wrong hypothesis of a Gaussian distribution of particle concentration (in reality, the spatial distribution of particles is random). It is a hypergeometric model that has been selected for the revision of this standard. If you have seen in the standard ISO 14644-1 of 1999 you will notice that all the calculations are made according to the normal law, like the average, the mean of the averages, the standard deviation and 95% upper confidence limit... then in reality the distribution of the particles in the air in a cleanroom it\u27s random, for this reason in this new version, it is a hypergeometric model that has been selected for the revision of this standard. In this article we have given a comparison between the two versions of the standard ISO 14644 part 1 and then it has been demonstrated by real case studies that the old version of the standard was based on the wrong hypothesis. After the comparison and study that we have done we encountered a contradiction among two versions of the standard IOS14644-1 (1999 and 2015), that we have treated in the same room, by the end of this experiment we drew out that the room is declared compliant in the new version 2015 and not compliant in the old version 1999, which aroused our curiosity to detect the error in the old version by this real case study
Ecological Approaches in Textile Sector: The Effect of r-PET Blend Ratio on Ring Spun Yarn Tenacity
As the strategy of waste-management, it is very important to ensure that waste materials are recycled and reused in different industry in order to protect the ecological environment and there are so many initiatives related to this subject. Especially in the textile industry, recycling of PET bottle waste into recycled polyester fiber (r-PET) has made a difference in the industry to reduce load on environment pollution. In addition, it contributes to reducing the fossil fuels sources, water and energy which is the required amount in the production of synthetic polymers. With supporting these attempts, we have to fulfill our social responsibility in order to preserve the ecological balance. This study aims to compare the tenacity and elongation properties of ring spun yarns produced from r-PET fibers recycled from waste PET bottles and cotton fiber at different blend ratios. Besides, virgin PET fibers were also used to conduct the difference between recycled and virgin fibers. Both r-PET and virgin PET fibers were blended with cotton as 100%, 70%/30%, 50%/50% and 30%/70% ratios. All production parameters were constant to determine the effect of raw materials on yarn tenacity and elongation. Results showed that ring spun yarns containing r-PET fibers had lower tenacity and elongation than virgin PET. On the other hand, the quality parameters of r-PET fibers can be improved by technological developments, and so they will be preferred to preserve the ecological balance
The Protection of Marine Aquatic Life: Green Port (EcoPort) Model inspired by Green Port Concept in Selected Ports from Turkey, Europe and the USA
Ecological Port, also known as Green Port (EcoPort), is an important development strategy protecting marine aquatic life and ecosystem. It provides business information on environmentally best practices and corporate responsibility centred around marine ports and terminals, including shipping, transport and logistics. Green Port concept gives a great opportunity to make transportation clean and efficient. Marine industry should adopt new legislations to create a clean future. It is the key point to implement strict liquid and solid waste policies and to begin to use low sulphur fuel and electric power whenever possible. Green Ports utilize electric powered cranes and they have strict garbage policies and well-educated personnel. Furthermore, the vessels entering Green Ports must have an accreditated waste management and bunkering plan. In this study, the implementation of the Green Port concept at some selected Turkish, European and the US Ports was given and a simple Green Port Model was prepared.

Uncertainty Balance Principle
The objective of this paper is to present new and simple mathematical approach to deal with uncertainty transformation for fuzzy to random or random to fuzzy data. In particular we present a method to describe fuzzy (possibilistic) distribution in terms of a pair (or more) of related random (probabilistic) events, both fixed and variable. Our approach uses basic properties of both fuzzy and random distributions, and it assumes data is both possibilistic and probabilistic. We show that the data fuzziness can be viewed as a non uniqueness of related random events, and prove our Uncertainty Balance Principle. We also show how Zadeh’s fuzzy-random Consistency Principle can be given precise mathematical meaning. Various types of fuzzy distributions are examined and several numerical examples presented
An in silico approach for structural and functional analysis of Heavy Metal Associated (HMA) proteins in Brassica oleracea
Heavy metal ATPases (HMAs) are the most important proteins involved in heavy metal accumulation process. Brassica oleracea has 5 HMA (1-5) homologues whose 3D structure has been predicted and validated in this study by different bioinformatics tools. Phylogenetic and multiple sequence alignment analyses showed high relationship between HMA2 and HMA4, while two same domains were identified in all five HMA proteins: E1-E2 ATPase and haloacid dehydrogenase (HAD) domain. Four HMA (2-5) proteins were identified to be localized in the plasma membrane, while HMA1 localization is predicted to be in plastid. Interactome analysis revealed high interaction of all HMA (1-5) proteins with many metal ion binding proteins and chaperones. Among these, interesting and strong interaction is observed between all HMA (1-5) proteins and ATX1, while HMA1, HMA2 and HMA4 have been found to strongly interact with FP3 (farnesylated protein 3) and FP6 (farnesylated protein 6) proteins. Docking site predictions and electrostatic potentials between HMA2/HMA4 and the interactome proteins were explained and discussed in this study
