In the research of intelligent sports vision systems, the stability and accuracy of vision system target recognition, the reasonable effectiveness of task assignment, and the advantages and disadvantages of path planning are the key factors for the vision system to successfully perform tasks. Aiming at the problem of target recognition errors caused by uneven brightness and mutations in sports competition, a dynamic template mechanism is proposed. In the target recognition algorithm, the correlation degree of data feature changes is fully considered, and the time control factor is introduced when using SVM for classification,At the same time, this study uses an unsupervised clustering method to design a classification strategy to achieve rapid target discrimination when the environmental brightness changes, which improves the accuracy of recognition. In addition, the Adaboost algorithm is selected as the machine learning method, and the algorithm is optimized from the aspects of fast feature selection and double threshold decision, which effectively improves the training time of the classifier. Finally, for complex human poses and partially occluded human targets, this paper proposes to express the entire human body through multiple parts. The experimental results show that this method can be used to detect sports players with multiple poses and partial occlusions in complex backgrounds and provides an effective technical means for detecting sports competition action characteristics in complex backgrounds.

This study examines critical factors in affecting halal business management, particularly challenges in Halal logistics implementation faced by the logistics service provider as well as its potential and opportunities for Halal based business in Indonesia. An In-depth, semi-structured interview is conducted to deepen the understanding and to provide detailed data of the study. The study found that there are several factors influencing halal logistics implementation. In terms of business strategy, there are external and internal factors that affect halal logistics practices. Such as market-driven, perception benefit of halal logistic certification followed by customer loyalty, challenges in implementing halal logistics, the complexity of operation halal logistics, and invariably regulation factors. All of those factors have become a prior factor in implementing halal logistics practices. The findings can provide a guideline in how to implement halal logistics practices in logistic service provider business, especially in transportation and warehousing process, along with the expected result for its business performance.

This essay compares the narratives that have emerged in recent years to describe the higher education enterprise with the narratives used to describe student affairs’ endeavors. I posit that the way in which student affairs professionals present their agenda is out of sync with the market-driven culture of the academy. The seven Principles of Good Practice are used to illustrate the incongruence between student affairs and academic affairs narratives on campus. I offer ways that those Principles can be recast to be more closely aligned with the new academic marketplace.

Chapter 3 demonstrates that DIY urban designers are largely motivated by failings they perceive in urban policy and planning. Placing them in this context is essential for interpreting the phenomenon. While do-it-yourselfers respond to the problems they see in creative ways, their individualistic tactics of doing so introduce problems of their own. The chapter focuses on bus stops to consider the lack of sidewalk seating in many cities, the privatization of street furniture, and concerns with local service provision. In trying to correct problems they see, do-it-yourselfers always impart their own personal and cultural values, and some DIY alterations can be selfish and anti-social in impact. The chapter interrogates DIY urbanism in the context of the “neoliberalized” city, arguing that even as the practices aim to counter the ill effects of market-driven planning, they can also reinforce an individualistic, undemocratic logic in placemaking.
