A feature-representation method for recognizing actions in sports videos on the basis of the relationship between human actions and camera motions is proposed. The method involves the following steps: First, keypoint trajectories are extracted as motion features in spatio-temporal sub-regions called “spatio-temporal multiscale bags” (STMBs). Global representations and local representations from one sub-region in the STMBs are then combined to create a “glocal pairwise representation” (GPR). The GPR considers the co-occurrence of camera motions and human actions. Finally, two-stage SVM classifiers are trained with STMB-based GPRs, and specified human actions in video sequences are identified. An experimental evaluation of the recognition accuracy of the proposed method (by using the public OSUPEL basketball video dataset and broadcast videos) demonstrated that the method can robustly detect specific human actions in both public and broadcast basketball video sequences.

In this article I examine recent debates concerning the emergence of cosmopolitan norms that protect individuals’ rights regardless of their citizenship status, and the spread of what some have called “global law without a state.” I distinguish between the spread of human rights norms and the emergence of deterritorialized legal regimes, by focusing on the relationship between global capitalism and legal developments arguing that “cosmopolitan norms” can enhance popular sovereignty while other forms of global law do not do so. The latter “fragment the public sphere” and create “privatized” norms of justification.I suggest that Israel inhabits three spatio-temporal modalities of sovereignty simultaneously, and this accounts for the enormously complex and existential nature of the dilemmas it faces: First, Israel is in a pre-Westphalian zone; second, for the Jewish population within its borders and for its one and a half million Arab citizens, Israel is a Westphalian state, which in fact exhibits strong features of a liberal, social democracy; and third, Israel is part of the global techno-economic complex. Within the three distinct spatio-temporal zones of sovereignty inhabited by contemporary Israel, one can detect new reconfigurations of sovereignty and citizenship that have not been exhausted.

Dynamic hand gesture recognition based on one-shot learning requires full assimilation of the motion features from a few annotated data. However, how to effectively extract the spatio-temporal features of the hand gestures remains a challenging issue. This paper proposes a skeleton-based dynamic hand gesture recognition using an enhanced network (GREN) based on one-shot learning by improving the memory-augmented neural network, which can rapidly assimilate the motion features of dynamic hand gestures. Besides, the network effectively combines and stores the shared features between dissimilar classes, which lowers the prediction error caused by the unnecessary hyper-parameters updating, and improves the recognition accuracy with the increase of categories. In this paper, the public dynamic hand gesture database (DHGD) is used for the experimental comparison of the state-of-the-art performance of the GREN network, and although only 30% of the dataset was used for training, the accuracy of skeleton-based dynamic hand gesture recognition reached 82.29% based on one-shot learning. Experiments with the Microsoft Research Asia (MSRA) hand gesture dataset verified the robustness of the GREN network. The experimental results demonstrate that the GREN network is feasible for skeleton-based dynamic hand gesture recognition based on one-shot learning.

Since the number of 3D models is rapidly increasing, extracting better feature descriptors to represent 3D models is very challenging for effective 3D model retrieval. There are some problems in existing 3D model representation approaches. For example, many of them focus on the direct extraction of features or transforming 3D models into 2D images for feature extraction, which cannot effectively represent 3D models. In this paper, we propose a novel 3D model feature representation method that is a kind of voxelization method. It is based on the space-based concept, namely CSS (Cube of Space Sampling). The CSS method uses cube space 3D model sampling to extract global and local features of 3D models. The experiments using the ESB dataset show that the proposed method to extract the voxel-based features can provide better classification accuracy than SVM and comparable retrieval results using the state-of-the-art 3D model feature representation method.

This paper maps the basic opposition groups that influenced the Egyptian political system in the last years of Hosni Mubarak’s rule. It approaches the nature of the relationship between the system and the opposition through use of the concept of “semi-opposition.” An examination and evaluation of the opposition groups shows the extent to which the regime—in order to appear that it was opening the public sphere to the opposition—had channels of communication with the Muslim Brotherhood. The paper also shows the system’s relations with other groups, such as “Kifaya” and “April 6”; it then explains the reasons behind the success of the Muslim Brotherhood at seizing power after the ousting of President Mubarak.

This study is based on the legal responsibility of the assessment of public appraisal reports they make in land procurement activities for development in the public interest. Public assessment is obliged to always be accountable for their assessment. The type of research found in this thesis is a type of normative legal research with the right-hand of the statue approach and case approach. Normative legal research is a study that provides systematic explanation of rules governing a certain legal category, analyzing the relationship between regulations explaining areas of difficulty and possibly predicting future development. . After conducting research, researchers found that one of the causes that made the dispute was a lack of communication conducted between the Government and the landlord. In deliberation which should be the place where the parties find the meeting point between the parties on the magnitude of the damages that will be given, in the field is often used only for the delivery of the assessment of the compensation that has been done.

The Relationship

Today in Germany, religion and the churches forfeit their sovereignty of interpretation and ritual concerning death and dying. The funeral director is the first point of contact when death occurs. Therefore he or she is able to influence the relationship between the living and the dead. In the course of this development, the dead body, often referred to as dirty and dangerous, is being sanitized by funeral directors. Funeral directors credit the dead body with a certain quality; they claim that facing the dead may lead to religious or spiritual experiences, and therefore they encourage the public viewing of the dead – a practice which was, and still is not very common in Germany. The new connotation of the dead body is an example for the dislimitation of religion in modern society. The religious framing of death-related practises no longer exclusively belongs to traditional religious institutions and actors, but can take place in commercial business companies as well.

In recent years, the number of forged videos circulating on the Internet has immensely increased. Software and services to create such forgeries have become more and more accessible to the public. In this regard, the risk of malicious use of forged videos has risen. This work proposes an approach based on the Ghost effect knwon from image forensics for detecting forgeries in videos that can replace faces in video sequences or change the mimic of a face. The experimental results show that the proposed approach is able to identify forgery in high-quality encoded video content.

According to Abdulaziz Sachedina, the main argument of religious pluralism in the Qur’an based on the relationship between private belief (personal) and public projection of Islam in society. By regarding to private faith, the Qur’an being noninterventionist (for example, all forms of human authority should not be disturb the inner beliefs of individuals). While the public projection of faith, the Qur’an attitude based on the principle of coexistence. There is the willingness of the dominant race provide the freedom for people of other faiths with their own rules. Rules could shape how to run their affairs and to live side by side with the Muslims. Thus, based on the principle that the people of Indonesia are Muslim majority, it should be a mirror of a societie’s recognizion, respects and execution of religious pluralism. Abdul Aziz Sachedina called for Muslims to rediscover the moral concerns of public Islam in peace. The call for peace seemed to indicate that the existence of increasingly weakened in the religious sense of the Muslims and hence need to be reaffi rmed. Sachedina also like to emphasize that the position of peace in Islam is parallel with a variety of other doctrines, such as: prayer, fasting, pilgrimage and so on. Sachedina also tried to show the argument that the common view among religious groups is only one religion and traditions of other false and worthless. “Antipluralist” argument comes amid the reality of human religious differences.

In the implementation of promotions in order to increase sales volume at the Pangkat - Kediri tile company, an analysis result of 6.00 was obtained which states that the relationship between promotion and sales volume is strong. Because promotion is one of the determining factors for the success of every company in producing to selling their products to consumers.Because the promotion includes many things starting from product strategy to product marketing / sales. However, companies certainly cannot only focus on promotional activities, because the four elements of marketing strategy (price, promotion, distribution and production) cannot be separated. So companies should be able to combine marketing strategies appropriately, so that the company is able to achieve the desired targets, namely achieving maximum profit. In order to introduce its company products to the public with advertising media is very important. Because with this advertising effort, society knows advantages that accompanied these products, so that the company's expectations for sales to increase will be even greater and its profits will also increase.Keywords:Promotion, sale, Marketing strategy and profit.
