This letter presents an automatic moving object detection method in image sequences captured from videos. While we focus on extracting objects throughout a frame sequence, our approach does not require any prior knowledge such as the background modeling nor interaction by users empirical thresholds tuning. Based continuous symmetric difference of adjacent frames, get full resolution saliency map current frame, which highlights with higher values and meanwhile inhibits background. Then,...

As one of the key characteristics software as a Service (SaaS), multi-tenancy aims to support massive customers by sharing application instances and databases. To achieve high economies scale, most issues needing be solved in real industry is that, given fixed number nodes, how optimally place on-boarding tenants maximize total supported without violating their SLA requirements. This paper focuses on this problem, which called On-line Tenant Placement Problem (OTPP). In order calculate...

The Chain-of-Thought (CoT) paradigm has emerged as a critical approach for enhancing the reasoning capabilities of large language models (LLMs). However, despite their widespread adoption and success, CoT methods often exhibit instability due to inability consistently ensure quality generated paths, leading sub-optimal performance. To address this challenge, we propose \textbf{Strategic Chain-of-Thought} (SCoT), novel methodology designed refine LLM performance by integrating strategic...

In Database-as-a-Service (DBaaS), a large number of tenants share DBaaS resources (CPU, I/O and Memory). While the provider runs to "share" across entire tenant population maximize resource utilization minimize cost, subscribe at low price point while still having conceptually "isolated" according service level agreements (SLAs). To optimize this dichotomy goals, we propose dynamic allocation framework that periodically re-allocates tolerating risk SLA violations. We model problem as...
