Let G be a group of order v. A k-element subset D of G is called a (v,k,λ )difference set in G if for any nonidentity element g ∈ G, there are λ pairs of elements d1,d2 ∈ D such that d1d 2 = g. It is well-known that difference sets can be used to construct sequences used in digital communication. This paper is a survey on the recent developments of using difference sets and their variations to ...

background: score worksheets have been extracted for phd candidates in epidemiology, microbiology and parasitology for the academic year of 1386-87. the main objective in this study is the impact and importance of different subjects on the discrimination results of admission. methods: extracted scores from worksheets are analyzed by minitab15 statistical toolbox. the regression values of differ...

In this paper, we consider a more general form of generalized abstract economy with a fuzzy constraint correspondence studied in [15, 17]. We establish some existence results for an equilibrium of our generalized abstract economy. We also consider a system of quasi-minimax inequalities and note that it is a unified model of several problems. As applications of our equilibrium existence results,...

We introduce a novel and simple method for assessing audiences’ emotional responses to audiovisuals (e.g. films). Viewers ( N = 21) watched movies TV commercials from different genres while wearing photoplethysmography (PPG) optic sensors on their wrists. Heart rate variability (HRV) synchrony was observed among the audience. Based this between-subject measure, we identified emotionally arousin...

Objective: The current state-of-the-art methods significantly improve the detection performance of steady-state visual evoked potentials (SSVEPs) by using individual calibration data. However, time-consuming sessions limit number training trials and may give rise to fatigue, which weakens effectiveness For addressing this issue, study proposes a novel inter- intra-subject maximal correlation (I...
