A polynomial is said to be unimodal if its coefficients are non-decreasing and then non-increasing. The domination of a graph G the generating function number dominating sets each cardinality in G, have been conjectured unimodal. In this paper we will show paths, cycles complete multipartite graphs unimodal, that almost every with mode $$ \lceil \frac{n}{2}\rceil .

One of the most common tasks of a robot companion in the home is communication. In order to initiate an information exchangewith its human partner, the robot needs to attract the attention of the human. This paper presents results of two user studies (N = 12) to evaluate the effectiveness of unimodal and multimodal communication cues for attracting attention. Results showed that unimodal commun...

Communicative feedback in human-human and human-computer interaction is of interest to both language and ICT researchers. In this study, unimodal and multimodal feedback, produced by Chinese and Swedish interlocutors, has been investigated in four Chinese-Chinese, four Swedish-Swedish, and eight Chinese-Swedish informal dyadic videorecorded dialogs. We are investigating two issues: First, what ...

By reexamining some initialization strategies for blind equalizers, we develop an approximation to a common contrast function for equalization which enjoys a “unimodal” property: the solution obtained from the modified criterion is unique to within standard scale factor ambiguity, and moreover yields a perfect equalizer whenever such is attainable. In the more realistic situation in which perfe...

Examples are given of tent maps T for which there exist nontrivial sets B ⊂ [0, 1] such that T : B → B is a homeomorphism.

SI Appendix 1: Experimental Localization of a Hopf Bifurcation Hartigans’ dip statistic was employed to experimentally identify the stiffness value at which a supercritical Hopf bifurcation occurred in an actual hair bundle (1-3). The position distribution for a quiescent bundle is unimodal, whereas a spontaneously oscillating bundle yields a multimodal distribution. Larger values of the dip st...

It is unknown if an Artinian level O-sequence of codimension 3 and type r (≥ 2) is unimodal, while it is known that any Gorenstein O-sequence of codimension 3 is unimodal. We show that some Artinian non-unimodal O-sequence of codimension 3 cannot be level. We also find another non-level case: if some Artinian algebra A of codimension 3 has the Hilbert function H : h0 h1 · · · hd−1 hd · · · hd }...

Grain size is a proxy indicator of airflow intensity and also provides scientific basis for the prevention dust hazards. However, variations in grain characteristics that occur during transport deposition processes are seldom discussed. Here, atmospheric samples were collected before after sand–dust storm analysis. The results showed distributions unimodal transportation but always became bimod...

Biometrics is the science and technology of measuring and analyzing biological data of human body, extracting a feature set from the acquired data, and comparing this set against to the template set in the database. Experimental studies show that Unimodal biometric systems had many disadvantages regarding performance and accuracy. Multimodal biometric systems perform better than unimodal biomet...
