Due to the increasing specialization of companies in a globalized world, inter-organizational process enactments have become increasingly relevant in recent years. Nevertheless there are hardly any scheduling approaches that meet the requirements of these inter-organizational processes, especially in terms of privacy aspects. In this paper we present a privacy-aware scheduling approach for hybr...

In many real time applications there is a need to represent many real time objects (universities, temples, airports, cities, buildings, lakes and companies etc) in the spatial database. Usually, spatial database objects are mapped with keywords for their reference in business or service applications. Normally, spacial objects are queried with the requirement of minimum inter object distance. No...

Wireless sensor network using IEEE802.15.4/ZigBee is gaining an exponentially increasing interest from industry and is considered as a universal solution for emerging application including home automation, health care, surveillance, and so on. To provide automation and remote control application service, wireless sensor network is inter-working with high speed Internet through Inter-networking ...

the present study aimed at investigating the specific discourse cycles of someintroductory textbooks across disciplines and languages to see to what extent theyacculturate students into the new subjects. to this end, 2 well-established and mostlyused english and persian introductory textbooks in sociology and 2 other wellestablishedenglish and persian introductory textbooks in linguistics were ...

objective: in view of the effect of hard labor on pregnancy outcomes and to determine risk factors, in this study, the effect of spacing between pregnancies was evaluated for probable effect on the incidence of dystocia in labor. materials and methods: this is a cross - sectional study used the records of 210 pregnant women referred to azad university hospitals between january 2000 and december...

We show that the moments of the trace of a random unitary matrix have combinatorial interpretations in terms of longest increasing subsequences of permutations. To be precise, we show that the 2n-th moment of the trace of a random k-dimensional unitary matrix is equal to the number of permutations of length n with no increasing subsequence of length greater than k. We then generalize this to ot...

Let 〈a1, a2, . . . , an〉 be a sequence of comparable elements. In this paper, we study two constrained versions of the longest increasing subsequence (LIS) problem. The first problem is the range-constrained longest increasing subsequence (RLIS) problem. Given 0 < LI ≤ UI < n and 0 ≤ LV ≤ UV , the objective of the RLIS problem is to deliver a maximum-length increasing subsequence 〈ai1 , ai2 , ....

The number of even 321-avoiding permutations of length n is equal to the number of odd ones if n is even, and exceeds it by the n−1 2 th Catalan number otherwise. We present an involution that proves a refinement of this sign-balance property respecting the length of the longest increasing subsequence of the permutation. In addition, this yields a combinatorial proof of a recent analogous resul...

where Rk,r is the number of permutations of the integers {1, . . . , k} that contain an increasing subsequence of length at least r. Let Xy denote a positive integer valued random variable such that Prob (Xy ≥ r) = F (r; y). If R k,r denotes the complement of Rk,r, i.e. the number of permutations σ ∈ Sk all of whose increasing subsequences have length strictly less than r, then clearly R k,r = ...
