Extremal Fuzzy Space
Get PDFThe extremal topology on an arbitrary set X was defined as a maximal non-discrete topology [1] and [2]. In this paper we introduce an extremal topology on a fuzzy set X, which is also a maximal non-discrete topology, and it has to be in a specific form. This form depends on some ultrafilters = . We consider some properties for this kind of topologies when = is free. The subspaces and the base of this topology is also considered
Mathematical Modeling of Host - Pest Interactions in Stage-Structured Populations: A Case of False Codling Moth [Thaumatotibia leucotreta]
Get PDFFalse codling moth (FCM) (Thaumatotibia lucotreta) is a significant pest due to its potential economic impact on many susceptible fruits in most temperate regions of the world. Efforts to control the codling moth in the past mostly relied on the use of broad spectrum insecticide sprays, which has resulted in the development of insecticide resistance, and the disruption of the control of secondary pests. Understanding the dynamic of this pest is of great in importance in order to effectively employ the most effective control strategies. In this study, a mathematical model of host-false codling moth interactions is developed and qualitatively analysed using stability theory of system of differential equations. The basic offspring number with respect to FCM free equilibrium is obtain using next generation matrix. The condition for local and global asymptotic stability of FCM free and coexistence equilibria are established. The model is analysed numerically and graphically represented to justify the analytical results
Armendariz Semirings and Semicommutative Semirings
Get PDFIn this paper we study Armendariz semiring, which has been introduced by V.Gupta and P.kumar, in the paper entitled `Armendariz and qusi-Armendariz and PS-semirings' [8]. We extend some results of Armendariz rings and semi-commutative rings of [3] for semirings with . (i)We obtain that for a semirings S, S is Armendariz if and only eS and (1+e)S are Armendariz for every idempotent e of S if and only if eS and (1+e)S are Armendariz for every central idempotent e of S. (ii) For a semiring S if S/I is an Armendariz semiring for some reduced ideal I of S then S is Armendariz
Applications of Probabilistic Methods on Some Stirling Sequences
Get PDFIn this paper, we investigate some combinatorial sequences based on the generalized Stirling numbers and the λ-analogues of r-Stirling numbers of the first kind, then derive their moment representations in use of probabilistic methods. We also provide identities related to r-Stirling numbers of the first kind, Stirling numbers and Daehee numbers
The Effect Of Village Fund Management Accountability In Aceh Singkil District, Indonesia
Get PDFThis study is conducted to address the effect of village fund management accountability in Aceh Singkil District of Indonesia. Using the factors of government internal supervisory, village apparatus competency and public participation, this study tried to test either partially or simultaneously on the management accountability of village funds. By selecting the population of all villages in Aceh Singkil District, which total of 116 villages in 11 districts, these research using purposive sampling method to curve the population. However, the sampling technique used stratified random sampling, totaling 46 villages including the village head, village secretary, treasurer, head of affairs and community leaders in each village. Utilizing the primary data of questionnaires from respondents, the research data was collected by using documentation techniques. The result of Multiple Linear Regression Analysis proved that the government internal supervisory and village apparatus competency influenced the management accountability of village funds in Aceh Singkil District. Alongside, public participation has no effect on the management accountability of village funds in Aceh Singkil District
The Effect of Hedonic Shopping Value on The Impulse Buying of Fashion Products of Generation Z
Get PDFImpulse buying has been an interesting discussion for more than half a century in various domains of study by business persons and researchers. The massive impulse buying done by consumers and higher profits gained by businesspersons are some of the reasons why impulse buying research needs to be done. Generation Z is one of the consumer groups that is believed to have the potential to do impulse buying. The high number of the population, the strong influence on family purchasing decisions, the fond of shopping, and the power of purchasing are the compelling reasons to further examine the impulse buying of generation Z. Internal factors,hedonic shopping value, can be the causes of impulse buying done by generation Z. This research aimed at determining the effect of hedonic shopping value on the impulse buying of fashion products of generation Z. The research method used in this research was causal research. The data was presented and analyzed using quantitative method. The data was collected by distributing questionnaires to 300 persons of generation Z that has been selected with purposive sampling method. The results of the research based on calculations using SEM AMOS 24 showed that hedonic shopping values had a positive and significant effect on the impulse buying of fashion products of generation Z
Density Matrix Method Begins To Occupy Leading Position In Quantum Physics
Get PDFThis article focuses on how quantum mechanics has been discovered and developed over the past century, and how its development has been hindered by many false theories. Some of these theories have come to light because a new tool has not yet been born that would ensure the existence of new theories. Other false quantum theories appeared due to the authors ignorance of the basics of quantum mechanics and are still taught to students.
This work opens up new paths of quantum physics that start with the Lindblad equation for the statistical operator and the equation for the density matrix. The last equation is equivalent to the equation for the statistical operator
Necessary forms of inclusion support for persons with cerebral palsy, hearing impairment and other associated difficulties
Get PDFPersons with cerebral palsy, hearing impairment and other associated difficulties need various forms of support. Support for these persons is inadequate, both due to the insufficient number of services provided by the system and largely due to the poor socio-economic status of these persons. The consequence of insufficient support, especially in the early period, is inadequate education and rehabilitation, which ultimately affects the social inclusion of these persons. The aim of the study is to examine the necessary types of support for persons with cerebral palsy, hearing impairment and other associated difficulties and to determine whether there is a statistically significant difference in the representation of the required types of support between cantons. The study was conducted on a sample of 120 respondents, persons with cerebral palsy, hearing impairment and other associated difficulties from four cantons of Federation of Bosnia and Herzegovina. Each canton consisted of one subsample of respondents. The results of the study showed that in addition to the existing support, 7.66% of persons with cerebral, hearing impairment and other associated difficulties need additional forms of support. Additional types of support mentioned by the respondents are: physical therapy (27.50%), more treatments (5.83%), professional help (5.00%), special education help (2.50%), school assistant help (3.33%), socialization (1.66%), all forms of support (8.33%), help from a speech therapist (11.66%), help from a psychologist (5.83%) and more socializing (5.00%). Respondents from all cantons need all these types of support and there is no statistically significant difference between cantons
Financial Policy and Taxation Relevancy in Theoretical and Practical Financial Economics
Get PDFThe foremost purpose of this paper is to concisely explain to individuals teaching economics in an academic setting or using economics in a practical setting some of the basics of long run financial theory and taxation items focusing on the dividend policy decision of a corporation. The main motivation for this study is based on observations of economists being very deficient in the discipline of finance and taxation especially in long run financial concepts. Many times practitioners or academics who are educated in the area of economics lack any type of background in finance and/or taxes and therefore are deficient with their knowledge of financial theory and applications. This disconnect prevents using many financial applications in their own classes, in their own businesses or with their own research. This paper serves as a primer to some of the long run dividend policy theories that individuals can use as a starting point to their additional research, study or use in teaching. Areas related to dividend policy and financial theory in general can be utilized by economists in academia and the private sector to enhance and advance their professional careers
