The concept of lower generalized order statistics was given by Pawlas and Szynal (2001). Later Burkschat et al. (2003) introduced it as dual generalized order statistics to enables a common approach to descending ordered random variables like reversed ordered order statistics, lower k records and lower Pfeifer records. With this definition we shall give explicit expressions for single and product moments of lower generalized order statistics from exponentiated Weibull distribution. Further, some of its important deductions and particular cases are discussed and a characterizing result of exponentiated Weibull distribution have been obtained using conditional moments of lower generalized order statistics.
In this paper explicit expressions and some recurrence relations are derived for marginal and joint moment generating functions of generalized order statistics from Erlang-truncated exponential distribution. The results for k-th record values and order statistics are deduced from the relations derived. Further, a characterizing result of this distribution on using the conditional expectation of function of generalized order statistics is discussed.
The ideal dispersion of an oral solid dose form is into the primary particles from which it was made. The proper disintegrant must be used in tablets and capsules that require quick disintegration in order to achieve maximum bioavailability. Solid dose forms are more effective when superdisintegrants are utilised. superdisintegrants reducing the disintegration time, These mixtures of substances that are added to the medicine formulation to help the content of tablets or capsules break down or disintegrate into tiny particles that dissolve more quickly Superdisintegrants are generally used at a low level , 1- 10 % by weight relative to the total weight of the dosage unit. The several types of these agents utilised in the formulation to deliver drugs more safely and effectively while maintaining patient compliance are covered in the current study.
Not only is medicine a science, but it is also an art. Instead of mixing pills and plasters, It addresses the basic functions of life that must be understood in order to be guided. Oral solid pharmaceutical dosage forms have been widely used for a long time, primarily due to their ease of use and effectiveness in delivering systemic medications. The tablets can be made from powders straight out of the container, from pellets or granules, or from several film-coated units.Tablets are classified as solid pharmaceutical dosage forms made by moulding or compression that contain medication ingredients with or without appropriate diluents. As a result, two general categories for tablets exist: compressed tablets and moulded tablets. Additional categories for compressed tablets include tablet triturates, chewable tablets, and directly compressible tablets.
In this note we give some recurrence relations satisfied by single and product moments of k-th upper record values from the exponential-Weibull lifetime distribution. Using a recurrence relation for single moments we obtain a characterization of exponential-Weibull, Weibull, exponential, Rayleigh and two parameter linear failure rate distributions.
In this paper we consider three parameter generalized exponential distribution. Exact expressions and some recurrence relations for single and product moments of lower generalized order statistics are derived. Further the results ar e deduced for moments of order statistics and lower records and characterization of this distribution has been considered on using the conditional moment of the lower generalized order statistics. , , , ( x F g x f x F r C x f r m r k m n r X r
In this paper we consider generalized Pareto distribution. Exact expressions and some recurrence relations for single and product moments of upper record values are derived. Further a characterization of this distribution based on condition al and recurrence relation of single moments of record values is presented.
