The increasing application of multi-modal large language models (MLLMs) across various sectors have spotlighted the essence their output reliability and accuracy, particularly ability to produce content grounded in factual information (e.g. common domain-specific knowledge). In this work, we introduce SimpleVQA, first comprehensive benchmark evaluate factuality MLLMs answer natural short questions. SimpleVQA is characterized by six key features: it covers multiple tasks scenarios, ensures...
When the background noise is large or sound source far away from microphone array, localization accuracy of target sources will decrease dramatically. In order to solve this problem, a method multi-aperture acoustic array based on time difference arrival(TDOA) proposed. The constructed by two small sub arrays, which supposed surpass performance equivalent composed all microphones. positions in local coordinates are separately estimated arrays generalized trust-region sub-problem modified...
Abstract Aiming at the thermal safety and inconsistency caused by high temperature of lithium‐ion (Li‐ion) battery, a cooling structure embedded with flat aluminum heat pipe (FAHP) for Li‐ion battery module is proposed. The three‐dimensional model FAHP established considering regionalized radiation. characteristics are compared four progressive schemes, performance affected different convection ( h conv ) radiation rad transfer coefficients analyzed. Results show that, more precise than that...
Abstract The vehicle's power battery is composed of a large number cells series or in parallel. Due to the manufacturing process error and different use environments, there are differences between cells, pack will have inconsistency problems, which increase safety hazard. Therefore, it great practical significance identify warn about batteries. Based on data internet vehicles platform, this paper proposes an improved isolated forest abnormal monomer identification early warning method, uses...
The performance of the suspension system is one most important factors in vehicle design. For double wishbone system, conventional deterministic optimization does not consider any deviations design parameters, so sensitivity analysis and robust are proposed. In this study, parameters positions key points, random uncertainties manufacturing. A simplified model established by software ADAMS. utilized to determine main variables. Then, simulation experiment arranged Latin hypercube adopted find...
For the coupling between modules in product family design, an approach to analysing coupled design for based on incidence path and correlation impact degree is presented. The of three cases discussed, i.e. platform modules, module customisation module, as well modules. Then interface among can be identified, instigating components are considered controllable factors experimental techniques utilised analyse their influence objectives. According analysis degree, implementation sequence...
The relation between two axioms in axiomatic design and robust has been discussed thoroughly, the inherent connection is revealed which indicates that satisfying above more robust. Furthermore, for some typical statistical distribution forms of product's quality characteristic, mathematical relationship information content loss as well signal-to-noise ratio established. virtue improving product also promoted. In end, practical examples are provided to demonstrate consistency design.
Robust performance is the most important concern in design of any product, especially system stage that precedes parameter design, because it actually determines attainable level product robustness phase. In this article, a framework modelling and analysis proposed, which includes modelling, cluster experiments. process metamodel general theory was utilized to describe function–structure model customer needs are transformed into functional requirements. Based on independent axiom zigzag...
Modular design is a widely used strategy that meets diverse customer requirements. Close relationships exist between parts inside module and loose linkages modules in the modular products. A change of one part or may cause changes other modules, which turn propagate through product. This paper aims to present an approach analyze associations impacts identify influential product design. The proposed framework explores all possible propagation paths (CPPs), measures impact degrees modules. In...
In order to increase the accuracy of path tracking, an improved model predictive control (IMPC) is proposed for autonomous vehicle under road conditions large curvature, which can enhance performances driving stability and safety. The controller design implemented in four steps. First, curvature ahead derived applied determine longitudinal velocity. Thus, velocity not assumed be constant, salient feature control. Second, kinematic established by Ackermann steering principle. Third,...
Mechanical components design is subjected to uncertainties in material and geometrical properties, loads other variables. For reliability optimization with uncertain parameters, based on the non-probabilistic theory, robust optimal method, parameters of mechanical are expressed by interval variables, a measure procedure for computation presented. Compared conventional probabilistic approach, proposed method does not require presumed probability distribution only bounds or ranges their...
In this paper, on the basis of comparison and analysis similarities differences design coupling between product family single product, a systematic approach to disposal is proposed, flow two level including strategy operation given. From platform plan, axiomatic theory utilized as framework analyze classify functional requirements, parameters are mapped with "zigzagging" mode, identified. view level, structure matrix (DSM) converted by DSM clustered grouped into modules, correlation...

During the configuration process of open architecture products (OAPs), adaptive change is inevitable to meet customers' personalised demands. However, coupling between modules makes changes more difficult. For in product design, an approach analysing proposed. The implications for are explained, and interface relationships among common platform, customised modules, analysed. modes three cases discussed, i.e. under same branch, different branches with only functional collaboration,...
Log parsing, a vital task for interpreting the vast and complex data produced within software architectures faces significant challenges in transition from academic benchmarks to industrial domain. Existing log parsers, while highly effective on standardized public datasets, struggle maintain performance efficiency when confronted with sheer scale diversity of real-world logs. These are two-fold: 1) massive templates: The most existing parsers will be significantly reduced logs growing...
In the domain of document AI, semi-structured form parsing plays a crucial role. This task leverages techniques from key information extraction (KIE), dealing with inputs that range plain text to intricate modal data comprising images and structural layouts. The advent pre-trained multimodal models has driven documents in different formats such as PDFs images. Nonetheless, endeavor is still encumbered by notable challenges like subpar capabilities multi-lingual diminished recall contexts...
Biodiesel/n-pentanol blend fuels have been regarded as the attractive alternatives for utilization of Diesel engines. However, fundamental studies low temperature combustion and soot formation characteristics biodiesel/n-pentanol in diesel engines are still scarce. The emission pure waste cooking oil biodiesel (B100) 70% biodiesel/30% n-pentanol (B70P30) were experimentally studied an optical engine present study.
