Abstract:

This paper introduces entropy quad-trees, which are structures derived from quad-trees by allowing nodes to split only when those correspond to sufficiently complex sub-domains of a data domain. Complexity is evaluated using an information-theoretic measure based on the analysis of the entropy associated to sets of objects designated by nodes. An alternative measure related to the concept of box-counting dimension is also explored. Experimental results demonstrate the efficiency of entropy quad-trees to mine complex regions. As an application, the proposed technique is used in the initial stag

Abstract:

Quad format as an instrument of the United States in competition with the People’s Republic of China In the last years, international tensions in the Indo-Pacific region have become more frequent and intense. Some of them are caused by the spectacular economic growth of the People’s Republic of China in the last 40 years, which implies Beijing’s increasingly assertive stance on the international stage and the growth of China’s military power. To counterbalance the growing power of the People’s Republic of China, Indo-Pacific countries will steadily increase their focus on opportunities to oper

Abstract:

The rise of the US-led Quad alliance in 2017 will be a test for ASEAN. Southeast Asia is at the center of a simmering strategic rivalry between the two world superpowers, the US and China. China's meteoric economic ascendence on the global stage has shifted the balance of global power in today's geopolitics. This article seeks to examine the potential of how the Quad may shake the ASEAN's unity and centrality as a result of China's rise. Beijing has expanded its influence throughout Southeast Asia and is by now easily ASEAN's largest trading partner, while at the same time it has aggressively

Abstract:

Knowledge graph question answering (KGQA) systems have an important role in retrieving data from a knowledge graph (KG). With the system, regular users can access data from a KG without the need to construct a formal SPARQL query. KGQA systems receive a natural language question (NLQ) and translate it into a SPARQL query through three main tasks, namely, entity and relation detection, entity and relation linking, and query construction. However, the translation is not trivial due to lexical gaps and entity ambiguity that may occur during entity or relation linking. This research proposed an ap

Its rotor-tilt mechanism controls 4 rotor-tilt angles independently and controls its roll and pitch angles similarly to a multirotor helicopter. It controls yaw angle by thrust vectoring and moves forward and backward by tilting its rotors. Rotor-tilting maneuvers are the initial stage of flight-mode transition between helicopter and fixed-wing modes.

Generating SPARQL queries from natural language questions is challenging in Knowledge Base Question Answering (KBQA) systems. The current state-of-the-art models heavily rely on fine-tuning pretrained models such as T5. However, these methods still encounter critical issues such as triple-flip errors (e.g., (subject, relation, object) is predicted as (object, relation, subject)). To address this limitation, we introduce TSET (Triplet Structure Enhanced T5), a model with a novel pretraining stage positioned between the initial T5 pretraining and the fine-tuning for the Text-to-SPARQL task.

At this R&D stage, each channel has a different biasing scheme to the photodiode for optimal coupling. A charge pump is implemented in one channel to provide a higher reverse bias voltage, which is especially important to mitigate radiation effects on the photodiodes.

Abstract:

Aiming at the problems of time-consuming and low diagnosis accuracy during the unsupervised training process of traditional DBN, an analog circuit fault diagnosis method based on Improved Multi-Objective Dragonfly Optimized Deep Belief Network (IMODA-ADBN) is proposed. The method employs an improved MODA algorithm instead of the BP algorithm, which improves the classification accuracy of the network and ameliorates the problem of being prone to falling into local optima. The algorithm is tested on three multi-objective mathematical benchmark problems and compared with three well-known meta-heu

Abstract:

The newest video coding standard, the versatile video coding standard (VVC/H.266), came into effect in November 2020. Different from the previous generation standard—high-efficiency video coding (HEVC/H.265)—VVC adopts a more flexible block division structure, the quad-tree with nested multi-type tree (QTMT) structure, which improves its coding performance by 24%. However, it also causes a substantial increase in computational complexity. Therefore, this paper first proposes the concept of a stage grid map, which divides the overall division of a 32 × 32 coding unit (CU) into four stages and r

Motivated by the MapReduce programming model, a well-adopted large-scale parallel data processing technique, we present a MapReduce-based polygon retrieval algorithm designed

However, the current research work undertaken for VVC is less for 3D video. In light of this context, we propose a fast coding unit (CU) decision algorithm based on the gray level co-oc

Based on the recognition of a theatrical work’s inherent ability to provide new insights concerning reality, the article concentrates on the way by which actors’ movements on stage create spatial diagrams that can provide new insights into the spectators’ world. The suggested model of theater’s epistemology results from a combination of Charles S.

The experimental results of the proposed methodology, which was tested using a 10 nm Advanced RISC Machine (ARM) Cortex-A9 quad-core central processing unit (CPU), indicated a performance gain of 6.1–8.4% compared with traditional AG design.

India’s foreign policy has evolved amidst numerous constraints and experienced many ups and downs in the process of its fruition to the present stage. In the years following the independence, India had to steer its foreign policy against the high wave of the Cold war. India’s bid to retain its independence in foreign affairs had often led India to compromise its strategic interests against Pakistan and China. Dynamics of the Cold war severed India’s relations with the West and reduced its foreign policy more or less to a ‘peace diplomacy’. The inbuilt idealism of India’s foreign policy was oft
