Opis:
The recently proposed q-rung dual hesitant fuzzy sets (q-RDHFSs) not only deal with decision makers’ (DMs’) hesitancy and uncertainty when evaluating the performance of alternatives, but also give them great liberty to express their assessment information comprehensively. This paper aims to propose a new multiple attribute decision-making (MADM) method where DMs’ evaluative values are in form of q-rung dual hesitant fuzzy elements (q-RDHFEs). Firstly, we extend the powerful Schweizer-Sklar q-norm and t-conorm (SSTT) to q-RDHFSs and propose novel operational rules of q-RDHFEs. The prominent advantage of the proposed operations is that they have important parameters q and r, making the information fusion procedure more flexible. Secondly, to effectively cope with the interrelationship among attributes, we extend the Hamy mean (HM) to q-RDHFSs and based on the newly developed operations, we propose the q-rung dual hesitant fuzzy Schweizer-Sklar Hamy mean (q-RDHFSSHM) operator, and the q-rung dual hesitant fuzzy Schweizer-Sklar weighted Hamy mean (q-RDHFSSWHM) operator. The properties of the proposed operators, such as idempotency, boundedness and monotonicity are discussed in detail. Third, we propose a new MADM method based on the q-RDHFSSWHM operator and give the main steps of the algorithm. Finally, the effectiveness, flexibility and advantages of the proposed method are discussed through numerical examples.

Opis:
Observations from mixtures of different subpopulations are common in biological and sociological studies. We consider the case, when the observations are taken from a set of groups containing subjects, which belong to different subpopulations. Proportion of each subpopulation in a group is known and can vary from group to group. Our aim is to estimate the means of an observed variable for subjects, which belong to each subpopulation. In this paper we consider the case, when subpopulations are defined by answers on so called “sensitive questions”. We consider some parametric and nonparametric estimates of the subpopulation means, such as weighted means, maximum likelihood and weighted least squares estimates. Finite sample properties of these estimates are analyzed. Mean square errors of the estimates are compared on simulated data. Some asymptotic results are also given.

Opis:
This research discusses a production scheduling by using flowshop type production scheduling with respect to transportation time, break-time and weight of jobs. The data used are four job scheduling on three machines. In addition, there is inter-machine transport time. The method was used in this research is NEH Method. Based on the results, the NEH method obtained a makespan value of 56 hours with a weighted mean flow time of 34.07 hours.

Opis:
It is observed that in some money exchange operations, every n-variable mean M applied by two market analysts who are acting in different countries should be self reciprocally conjugate. The main result says that the only homogeneous weighted quasi-arithmetic mean satisfying this condition is the weighted geometric mean. In the context of invariance of the geometric mean with respect to the arithmetic-harmonic mean-type mapping, the possibility of the occurring reciprocal-conjugacy in technical sciences is commented.

Opis:
Human activity is main source of all environmental pollutions. Noise is common environmental issuesthat cannot be generated without geospatial location. It has great impact on mankind such as physical disturbance, physiological disturbance and affects human health. The aim of this research work is to identify the geospatial noise level and mapping noise vulnerability in some part of Ibadan North East Local Government Area. DSLM and GPS are used for survey method in which sixteen different location points were selected for noise vulnerability. The Mathematical Model is used to calculate Equivalent continuous sound level for morning, afternoon and evening (Lm_a_e), mean noise level for the morning, afternoon, evening and Daily Average of Noise values were generated. World Health Organization (WHO) recommendation standard was used as a standard in this research because Nigeria Noise pollution bill is still under consideration in the National Assembly. ArcGIS software was used for analysis and noise zones were carved out based on WHO yardsticks. Noise vulnerability mapping generated shown that land uses within the study area were experiencing very higher noise levels which are risky to the environment and society. Environmental agency and Government should set standard values for the noise barriers by passing the noise bill in the National Assembly assiduously and soonest.

Opis:
Record linkage is a technique used to link records from one database with records from another database, making reference to the same individuals. Although it is normally used in database integration, it is also frequently applied in the context of data privacy. Distance-based record linkage permits linking records by their closeness. In this paper we propose a supervised approach for linking records with numerical attributes. We provide two different approaches, one based on the weighted mean and another on the OWA operator. The parameterization in both cases is determined as an optimization problem. We evaluate our proposal and compare it with standard distance based record linkage, which does not rely on the parameterization of the distance functions. To that end we test the proposal in the context of data privacy by linking a data file with its corresponding protected version.

Opis:
A general equation, combining the Pythagorean and Sauter-type formulas, which can be used for calculation of a mean of a set of values is given and discussed in the paper. A classification of means, forming the Extended Pythagorean Means family, including power (arithmetic, geometric, quadratic, cubic, etc.), inverted power (harmonic, inverted quadratic, inverted cubic, etc.), and Sauter-type (volumesurface, volume-length, etc.) is presented. The calculated means, depending on their type, are different. Formulas for calculating mean values for a set of values treated individually, in groups and as a fraction (weighted mean) are also given.

We study boundedness properties of commutators of general linear operators with real-valued BMO functions on weighted $L^p$ spaces. We then derive applications to particular important operators, such as Calderón-Zygmund type operators, pseudo-differential operators, multipliers, rough singular integrals and maximal type operators.
