Abstract:

The soft set theory offers a general mathematical tool for dealing with uncertainty, fuzziness and vagueness. The concept of soft sets which can be seen as a new mathematical approach to vagueness is used in many applications including decision making and medical diagnosis problems. Later, it is generalized to soft fuzzy set. In this paper we present the definition and operations of soft intuitionistic fuzzy set. Furthermore, based on the analysis of several operations on soft intuitionistic fuzzy set in the study, we provide some new notions such as the restricted intersection, the restricted union and the restricted difference of two soft intuitionistic fuzzy sets. We also improve the notion of complement of a soft intuitionistic fuzzy set and prove certain De Morgan's laws hold in soft intuitionistic fuzzy set with respect to the new definitions..

Abstract:

Environmental conditions affect concrete in different ways, which threatens the durability of this concrete. Among the environmental parameters that affect the durability of concrete is the change in outdoor temperature, between day and night, summer and winter. This paper reflects the experimental work carried in order to better understand the effect of temperature variations on some durability aspects of an ordinary concrete frequently used in Morocco for big infrastructure construction sites. To do this, samples of concrete were made, in order to conduct in the laboratory a series of tests, which allowed us to determine the values of some durability parameters such as mechanical strength to compression, porosity to water, gas permeability, electrical resistance, chloride ion diffusion coefficient....

Abstract:

This paper presents the application of the Analysis and Problem Solving Method (MASP) in the reduction of losses and the search for higher productivity of the forged part polishing sector. The decline of the demand for hand tools such as the forged hammer causes a reduction in the utilization of productive capacity and a decrease in the labor employed. The objective of this paper is to identify opportunities for improvements in sanding and polishing line productivity. The purpose also contemplates the organization of the sector to improve performance in the development and maintenance of the company's competitiveness. The methodology used was a case study. From the analysis of losses and the use of quality tools, it was possible to propose inexpensive and straightforward actions, improving the organization of the sector, reducing production times, as well as reducing ergonomic risks.

Abstract:

Curriola fruit (Pouteria ramiflora) is a fruit of the Brazilian Cerrado (a type of savannah) that is recognized for its pronounced and remarkable aroma. In this work, the effect of ripening on the volatile profile of curriola fruit was evaluated using solid phase micro extraction (SPME) combined with gas chromatography and massspectrometry (CG-MS). Ester was the major class of compounds identified in the volatile profile of curriola fruit. Followed alcohols and sesquirterpenes. The major volatile compounds identified in curriola fruit were ethyl butanoate, ethyl hexanoate, ethyl octanoate, ethanol, ethyl-(Z)-3-hexenoate, β-curcumene, -curcumene,α- bergamotene (cis), α-curcumene, and (E)-2-hexenal. The largest changes observed in volatile constituents during ripening of curriola fruit were decreases in alcohols, aldehydes, and sesquiterpenes as well as an increase in esters.

Abstract:

In this paper we are discussing the classification technique of separation of ham and spam. The problem at hand is to classify and email as spam or non spam given features of the email message and we have seen a second what kind of features can be used to qualify and email which would make it distinctive for a class spam classifier. So, the probability of spam given features of a message is what we have to estimate, and this is actually the posterior probability of the class spam. By base rule as the likelihood of the features of the email message given then it was a spam message times the prior probability of spams divided by the features of the message

Abstract:

Increased interest in biometric security systems makes face recognition a very effective research area. Now, we will take a look on basics of a face recognition system. In an image a face region is present where only facial features are present. In another terms it means we have to localize or concentrate only on the face region that means we are contemplating those parts of an image where a face may present. This research provides an up-to date survey of various existing recognition techniques but also represent precise descriptions of some methods. In addition to this other topics like issues of illumination and pose variation are also discussed in their work. The purpose of this short review paper is to present, categorize and evaluate some new face detection techniques using four conventional learning machine. The performance and the other evaluation parameters of these methods compare with each other in order to introduce significant techniques and also to state advantages and disadvantages of related works

Abstract:

A time series is a sequential set of data points, measured typically over successive times. The measurements taken during an event in a time series are arranged in a proper chronological order.A time series containing records of a single variable is termed as univariate, and more than one variable a multivariate.Here in this research paper we have collected the data of time square mall and predict the sale forecast for the ten new time steps. Here we have used ARMA and ARIMA model which are robust statistical tools.Because it is the human spirit expectations and demand for uncertain environment, and the volatile dynamic that has mass. Here wetry to make the best advice that is, if possible, to reduce uncertainty in the business or to eliminate it..

Abstract:

In the era of wireless communication system as the application development scenario is increasing rapidly. Vanet is basically a vehicular ad hoc network which is defined in the IEEE 802.11p Standard for better adaptability in the wireless network environment that basically provide the communication among both vehicle to vehicle and vehicle to infrastructures because having the distributed environment, security emerges as an important issue. The transmission of the data is performed under the untrusted network environment. The authenticity is vulnerable to different security attacks. Wormhole attack is one of the serious kind of attack on the wireless sensor network In which packets are captured by a malicious node that perform tunneling from one location to the another location and also transmit them into the established network. In this paper we discuss about

Abstract:

The aquatic ecosystem plays a vital role in the development of human society. It not only provides human beings with basic products for life and production, but also functions to maintain ecosystem structure, ecological processes and regional ecological environment. Assessment of aquatic ecosystem health is the focus and difficulty in the field of aquatic ecology research. It needs to be further developed in research methods and theories. At present, there are two main methods for health assessment of aquatic ecosystems: the index system method and the indicator species method........

Abstract:

Worldwide, a great deal of research is currently being conducted concerning the use of fibre reinforced concrete. Fibre reinforced concrete application is a very effective way to strengthen structures where in order to increase their life span. Fibres are currently being specified in tunnelling, bridge decks, pavements, loading docks, thin unbounded overlays, concrete pads and concretes slabs. Fibre reinforced concrete (FRC) is concrete containing fibrous materials which increase its structural integrity. It contains short discrete fibres that are uniformly distributed and randomly oriented. Fibres include steel fibres, glass fibres, synthetic fibres and natural fibres.

Abstract:

In order to implement a neural network-based cryptosystem, a hardware platform with high speed and high efficiency is required, therefore the Field Programmable gated Array (FPGA) is said to be the most suitable choice in order to implement this system. Due to the features of pipelining technique, the neural network was built by using it in order to minimize the connection between the neurons. My proposed system shows the final hardware implementation of NN-based cryptosystem that is attained through programming the (Xilinx XCVirtex –E Family). The data bus used is 128bits with a maximum clock frequency of (500MHz) and throughput of (4Gbps) per neural network. The tool I have used in the implementation of the system was (Foundation ISE 3.1i)..
