Absence of the user based recommendation system is a prevalent problem in a social network. In this paper, our work tends to model distance based group and probability based group in terms deciding recommendation dynamics. Here, we want to identify the best user who appears to be the innocent audience. In this regard, the effect of network density and preference homogeneity according to the user have been calculated. We have also used the probability function to evaluate the group of user that could be recommended.
In this paper I consider how information is required to specify various systems. It is shown that the transitive information of any physical system, is distributed among three distinct components. One of these, the se...

Efficiency of MAC (media access control) is one of important issues of power line communication (PLC). There exists efficiency problem in current CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) mechanism of large-scale PLC network. Aimed to solve this problem, a Cluster and probability Competition Based MAC (CP-MAC) mechanism is presented to improve the MAC efficiency, in which the network is divided into clusters and competition is conducted among clusters using the probability-function. Finally the simulation results show that the CP-MAC is able to improve the LPLC network performance in term of packet loss rate, throughout and delay.

Of all the probability distributions considered during the calculation of Measurement Uncertainty, the U-Shaped distribution is generally least familiar to the typical EMC Engineer. A previous paper [3] attempted to demystify the distribution by demonstrating that it occurs naturally when considering the Voltage Standing Wave (VSW) amplitude generated along the length of a semi-infinite cable by impedance mismatch at its termination. This paper seeks to continue the demystification by presenting additional background unlikely to he familiar to the typical EMC Engineer. Specifically, the origin of the 1/root 2 Normalisation Factor, used to determine the standard uncertainty contribution due to mismatch, is presented, as is the relationship between the U-Shaped Distribution and the Beta and Gamma Distributions.

An Urban Distribution Center (UDC) is a useful City Logistics policy instrument. A UDC is a logistic site dedicated to decompose and consolidate freight directed to the city, by planning the routes and service time, restricting the traffic of trucks and increasing the load factor of feeder vehicles. A UDC can produce interesting impacts on the dynamics of urban freight distribution, but its success depends on many factors: an appropriate location;a well-balanced presence of spaces and equipment;an efficient and effective organization of internal services;a connection with the surrounding area and with the related transport services;a management structure that meets different and complementary requirements;a capacity to support itself. The paper proposes an analysis of the functional organization of a UDC through a "what if" micro-simulation approach aimed at the UDC efficiency control. After a review of the state of the art, a procedure to implement a discrete-event micro-simulation model is described. probability functions concerning the times of UDC activities are proposed.

In this thesis we investigate some globaldesiderata for probabilistic knowledge merging given severalpossibly jointly inconsistent, but individually consistentknowledge bases. We show that the most naive methods of merging,which combine applications of a single expert inference processwith the application of a pooling operator, fail to satisfy certainbasic consistency *** therefore adopt a differentapproach. Following recent developments in machine learning whereBregman divergences appear to be powerful, we define severalprobabilistic merging operators which minimise the joint divergencebetween merged knowledge and given knowledge bases. In particularwe prove that in many cases the result of applying such operatorscoincides with the sets of fixed points of averaging projectiveprocedures - procedures which combine knowledge updating withpooling operators of decision theory. We develop relevant resultsconcerning the geometry of Bregman divergences and prove newtheorems in this field. We show that this geometry connects nicelywith some desirable principles which have arisen in theepistemology of merging. In particular, we prove that the mergingoperators which we define by means of convex Bregman divergencessatisfy analogues of the principles of merging due to Konieczny andPino-Perez. Additionally, we investigate how such merging operatorsbehave with respect to principles concerning irrelevantinformation, independence and relativisation which have previouslybeen intensively studied in case of single-expert ***, we argue that two particular probabilisticmerging operators which are based on Kullback-Leibler divergence, aspecial type of Bregman divergence, have overall the most appealingproperties amongst merging operators hitherto considered. Byinvestigating some iterative procedures we propose algorithms topractically compute them

Energy consumption of agricultural production is increasing and rural urbanization has become a serious issue waiting for people to solve. Agriculture & Solar complementary roof power generation projects can make the sustainable development of agricultural production and solve the negative effect of the rural urbanization. But in the decision-making of the agriculture & solar complementary roof power generation, there are some problems: first, it is lack of the criteria system and the effective decision model to help the decision makers. Second, the weight calculation is usually more complicated, and the calculation of the entropy weight cannot fully reflect the information important degree. Third, interval number group decision making method has a great many uncertainties. So in order to solve the above problems, the following work has been done in this study: the criteria system of the Agriculture & Solar complementary roof power generation project is analyzed and established;the modified interval entropy method determines the weight of criteria and sub-criteria for solving the defects of the weight calculation. Next, the methods of describing the interval numbers with probability function and the modified dominance is proposed to to improve the accuracy of decision-making. Finally, a case study is given and by sensitivity analysis verified the reliability and operability. (C) 2017 The Authors Published by Elsevier Ltd.
