With the fast development of logistics industry, logistic tracking services has drawn more and more attention around the world. However, conventional logistics systems are difficult to provide efficient and whole-ranged logistic tracking services for customers. In this paper, we design and implement a cloud computing supported logistics tracking information management system to support whole-ranged and real-time logistics tracking services. The proposed solution is based on technologies related to cloud computing and a few Internet of Things technologies such as two-dimensional code scanning and identification, GPS location and image recognition. The main technical issues in our proposed system model include security management, logistics vehicle management, user management and location information management. Through the implementation and evaluation, we show the feasibility and efficiency of our proposed solution.

Developing deep generative models has been an emerging field due to the ability to model and generate complex data for various purposes, such as image synthesis and molecular design. However, the advancement of deep generative models is limited by challenges to generate objects that possess multiple desired properties: 1) the existence of complex correlation among real-world properties is common but hard to identify; 2) controlling individual property enforces an implicit partially control of its correlated properties, which is difficult to model; 3) controlling multiple properties under various manners simultaneously is hard and under-explored. We address these challenges by proposing a novel deep generative framework, CorrVAE, that recovers semantics and the correlation of properties through disentangled latent vectors. The correlation is handled via an explainable mask pooling layer, and properties are precisely retained by generated objects via the mutual dependence between latent vectors and properties. Our generative model preserves properties of interest while handling correlation and conflicts of properties under a multi-objective optimization framework. The experiments demonstrate our model's superior performance in generating data with desired properties. The code of CorrVAE is available at https://github.com/shi-yu-wang/CorrVAE.
