As an application of Clifford theory, we are interested in a situation in which every irreducible projective character of a finite group G is an induced character of an irreducible linear character of some subgroup H of G. For this purpose, we study relative projective monomial groups with respect to subgroups.

In this paper, we prove that the image of the representation of the automorphism group of a supersingular K3 surface of Artin-invariant 1 over odd characteristic p on the global two forms is a finite cyclic group of order p + 1. Using this result, we deduce, for such a K3 surface, there exists an automorphism which cannot be lifted over a field of characteristic 0.

There are limited research questioning the relationship between the disabled community and media, particularly in Malaysia. The lack of awareness and common assumption of specialty towards the disabled community have caused a small amount of local disability researches that question the relationship between the disabled community and the media. This research aims to find out the types of representation of disability in the Malaysian mainstream media, particularly press. Interview with visual disabled personnel and content analysis from news coverage of mainstream press are deployed in the study. The findings indicated the invalidity of disability culture as the misrepresentation of disabled community in Malaysia is not as severe as depicted by scholars because the news coverage focusing on them is getting more positive. Besides that, disabled people are not defensive towards the terms used to refer them as long as media practitioners do not over amplify their disability. The application of charity approach is still common in news coverage to portray the disabled community as victim, and therefore they are partially marginalized due to the misrepresentation in Malaysian mainstream press.

In life insurance the goal of medical examination is to exclude medical, environmental adverse-selection to the utmost. And keeping the principle of equity and the homogeneity of risk in the group of the insured, you are able to manage the company reasonably and realize the orginal ideal of life insurance, namely, the mutual assistance. And yet, the cases of the misrepresentation have been occurred frequently so far. As a result of them, the development of life insurance industry has been obstructed, and public criticism has been caused. Carrying medical examination, you have to know how the representation is important, And citing what the misrepresentation and false representation influenced the results, I want you to refer to medical exam-business.

The presence of cracks changes the water content pattern during seepage through a cracked soil as compared to that of intact soil. In addition, several different crack networks may form in one soil type. These two factors result in a variation of water contents in the soil matrix part of a cracked soil during seepage. This paper presents an investigation of the effect of crack network representation on the water content of the soil matrix part of cracked soil using numerical models. A new method for the numerical generation of crack networks incorporating connections among crack endpoints was developed as part of the investigation. Numerical analysis results indicated that the difference in the point water content was large, whereas the difference in the average water content was relatively small, indicating the uniqueness of the crack network representation on the average water content of the soil matrix part of cracked soil.

The Inter-Channel Level Difference (ICLD) is a cue parameter to estimate spectral information in a binaural cue coding that has been recently in the spotlight as a multichannel audio signal compression technique. Even though the ICLD is an essential parameter, it is generally distorted by quantization. In this paper, a new modified ICLE representation method to minimize the quantization distortion is proposed by adopting a flexible determination of the reference channel and the unidirectional quantization. Our experimental result confirms that the proposed method improves the multichannel audio output quality even with the reduced bit-rate.

– In the paper, to handle the problem of traditional bag-of-features model ignoring the spatial relationship of local features in human action recognition, we proposed a Multiscale Spatial Position Coding under Locality Constraint method. Specifically, to describe this spatial relationship, we proposed a mixed feature combining motion feature and multi-spatial-scale configuration. To utilize temporal information between features, sub spatial-temporal-volumes are built. Next, the pooled features of sub-STVs are obtained via max-pooling method. In classification stage, the Locality-Constrained Group Sparse Representation is adopted to utilize the intrinsic group information of the sub-STV features. The experimental results on the KTH, Weizmann, and UCF sports datasets show that our action recognition system outperforms the classical local ST feature-based recognition systems published recently.

Let G be a compact abelian Lie group, and M an odd-dimensional closed smooth G-manifold. If the fixed point set $M^G\neq\emptyset$ and dim $M^G=0$, then G has a subgroup H with $G/H{\cong}\mathbb{Z}_2$, the cyclic group of order 2. The tangential representation $\tau_x$(M) of G at $x{\in}M^G$ is also regarded as a representation of H by restricted action. We show that the number of fixed points is even, and that the tangential representations at fixed points are pairwise isomorphic as representations of H.

We develop a framework to construct geometric representations of finite groups G through the correspondence between real toric spaces $X^{\mathbb{R}}$ and simplicial complexes with characteristic matrices. We give a combinatorial description of the G-module structure of the homology of $X^{\mathbb{R}}$. As applications, we make explicit computations of the Weyl group representations on the homology of real toric varieties associated to the Weyl chambers of type A and B, which show an interesting connection to the topology of posets. We also realize a certain kind of Foulkes representation geometrically as the homology of real toric varieties.

The history of war is the interesting theme to every group because it presents the identity of nation and social aspects of the age. The war was a subject matter in culture industry, and the war films represented a battlefield with various phases. Thus, it provided important description to understand our society. The purpose of the study is to identify the phases and representation of war in films through analyzing a pattern of war films. For the comparison study on a type of war and its social effect, we need to approach the concept of inclusive representation. Thus, I categorize war films to suit the subject of research and select the objects among the various war films. On the basis of these films, this paper studies how the representations and phases of war is reflected and described in contents of films.
