The roles of drilling fluid in the drilling process are so clear and essential. The objective of designing drilling fluid for extreme and deep environment (HPHT wells) is to develop high performance drilling fluid system in well bore to achieve zonal isolation. The primary objective of drilling fluid is to improve thermo electrical and rheological properties and displacement efficiency of drilling fluid system. Oil well slurries depend on its homogeneity of additive concentrations, quality and quantity to contribute the placement and success of a well drilling cementing operation. The experiments show the increase in the amount of plastic viscosity due to the increase in the amount of nano ferric oxide. Also, the increase in the amount of nano particle increases the amount of viscosity of slurry. It seems each extra 0.2% nano oxide increases the viscosity about 0.2 Pa.s from 0.2% to 0.6%.

Experiments are held to investigate the effect of ferric oxide nano particles on the thermo electrical properties of drilling slurry. The main purpose of this study is to improve the thermo electrical properties of drilling slurry by nano ferric oxide. The objective of designing drilling fluid for extreme and deep environment (HPHT wells) is to develop high performance drilling fluid system in well bore to achieve zonal isolation. So, the thermal conductivity, electrical conductivity and overall heat transfer coefficient are investigated in this paper. Results show the behavior of nano drilling fluid in the conduction mechanism can followed by polynomial with order 3th. The experimental results show the heat transfer with two mechanisms of convection and conduction can increase with increasing the percentage of used ferric oxide. This characteristic can be introduced in the novel drilling fluid.

This paper proposes the application of particle swarm optimization (PSO) technique to oil and gas pipeline under spatially varying corrosion defects. The PSO results show that to keep the oil flowing in the pipe and still minimize the corrosion rate the pipeline system should be at its optimum performance values, that is, the optimum corrosion rate obtained from the PSO is 0.0277mm/year and this is achievable at optimum water cut of 11.41%, temperature of 30.750C, pH value of 5.66, pipe age not more than 10years, fluid flow velocity of 2.69m/s, partial pressure of CO2 at 0.2MPa and hydrogen sulphide concentration not more than 0.1mol/L. The PSO results also show that higher temperatures and age of pipe will drastically increase the corrosion rate. From the PSO results, it is clear that the pipe thickness will be reduced by a maximum of 0.277mm and a minimum of 0.1579mm after 10 to 50years of continuous operation.

Sentiment Analysis which frequently passes by the name opinion mining is one of the noticeable field in lots of research is going ahead because of its interminable application like online networking monitoring, product reviews and so on. Be that as it may, because of the noticeable utilization of social media the utilization of multilingual statements has turned out to be most basic as client tends to in their own particular safe place. These multilingual statements emerge due the utilization of more than one language to create a statement. Because of absence of clear grammatical structure it is exceptionally hard to discover correct sentiment out of it. This paper presents the analysis of sentiments of 4 languages tweets by applying Naïve Bayes algorithm. Our proposed method, effectively identify the sentiments of the users by utilizing their twitter walls comments and posts. We have analyzed a very famous movie, “Baahubali” with hash tag of “Baahubali2”.

There has been incessant falling/toppling (a rollover) of fluid conveying tank cars especially petroleum products Conveying tank cars in Nigerian roads. This has led to loss of lives, petroleum products, vehicles and roads’ environmental degradation surfaces damage that cannot be accounted for. This paper investigates critically the factors that are responsible for this menace and likely engineering suggestions and solutions are provided for future design adaptions and knowledge for the producers and users of petroleum Tank cars. Accidents, wastage of petroleum products, loss of these vehicles and spoilage of the road surfaces are grievous conditions that will incur debts or lost on the hands of marketers, petroleum companies – like NNPC etc. will be greatly minimized.

Speech enhancement aims to improve speech quality by using various algorithms. The objective of enhancement is improvement in intelligibility using audio signal processing techniques. The choice of the filter-bank has a significant influence on the performance of such systems in terms of signal quality, computational complexity and signal delay. Accordingly, the filter-bank design has to fulfill different, partly conflicting requirements in dependence of the considered application. In this paper we tried to design Low Pass, High pass & band pass Filters to process Natural Spoken Marathi alphabets. We also processed Segmented & overlapped Alphabets to compare our algorithm performance. Major perspective to design filter bank is to select particular filter band to process respective vowel & consonant.

The new professional farmer is the hard core to promote the transformation of Heilongjiang Province from the big agricultural province to the strong agricultural province. The practice path of innovating the training of new professional farmer is the necessary way to accelerate the cultivation of new professional farmers in Heilongjiang Province. This paper explores the main problems in the training of new professional farmers in Heilongjiang Province from four aspects: training object, training teacher, training mode and training subject, and puts forward the concrete strategies of innovating the training practice path of new professional farmers. Specific strategies are as follows. First, we should aim at training objects and establish a "training object library". Secondly, we should choose excellent teachers and establish a "double teacher" faculty.

Landfill leachate is a fluid that is from the external water which enter into the landfill solid waste, dissolve and rinse the dissolved materials including organic matter. It usually has high content of organic matter, electrical conductivity and high concentrations of nitrogen, toxic compounds and heavy metals. Hence, formation of landfill leachate threatens the public health and environment. Proper treatment of landfill leachate is therefore vital to remove hazardous components before discharge. Further, composition of landfill leachate varies from time to time and site to site. There are number of leachate treatment methods which have been used. Some methods are inefficient, and some are expensive and energy consuming and thus not suitable for many landfill sites, particularly in rural areas of developing countries.

The injection of PVC polimers with a molded has been studied. Experimentally, parameters were measured for different processing conditions. Injection molding is the most widely used process in manufacturing plastic products. An empirical model to decide the shrinkages of thermoplastic polymers in the injection process. Polyvnyl chloride was used in this study to test the effectiveness of the model. Comparing the calculated results, it was found that the shrinkage ratio obtained with the present model are in agreement with those obtained by using inline processes. ANN method, a Levenberg Marquardt algorithm neural network model is developed to map the complex non linear relationship between process conditions of the injection molded parts an ANN model. This method is used in the process optimization for an industrial part in order to improve the volumetric shrinkage variation in the part.

The penetration of smartphones within enterprises is rapidly increasing, so as the usage of it. Nowadays, Android applications are used widely in enterprise software to support their system. Software systems like SAP and IFS has their own mobile apps as a part of their software solutions, especially in field service domain. These enterprise mobile applications are not usually one single application. Rather it might be several apps that are inter related and communicate with each other. A number of ways are available which aids inter application communication. One way of such inter app communication is using "intents". Intents are simple message objects that are used to communicate from one activity to another. Intents could be also defined as the intention of an application. Although the intents are used in inter apps communication, the problem with intents is that they are not secure. Even Android Operating System doesn’t claim that these intents are secure. Therefore our research aims at finding how intents messages could be encrypted for enterprise systems considering high security, light weight ness and fast processing such that it would not be easy to crack.
