The application of information retrieval techniques to search tasks in software engineering is made difficult by the lexical gap between queries, usually expressed natural language (e.g. English), and retrieved documents, code programming languages). This often case bug feature location, community question answering, or more generally communication technical personnel non-technical stake holders a project. In this paper, we propose bridging projecting statements snippets as meaning vectors...

This paper proposes a method for planning the three-dimensional path low-flying unmanned aerial vehicle (UAV) in complex terrain based on interfered fluid dynamical system (IFDS) and theory of obstacle avoidance by flowing stream. With no requirement solutions to equations under boundary conditions, proposed is suitable situations with different shapes obstacles. Firstly, transforming mountains, radar anti-aircraft fire into cylindrical, conical, spherical, parallelepiped obstacles their...

The chronic digestive condition gallstones is quite common around the world, development of which closely related to oxidative stress, inflammatory response and abnormalities lipid metabolism. In last few years, as a novel biomarker metabolism, non-high-density lipoprotein cholesterol high-density ratio (NHHR) has garnered significant interest. However, its relationship with not been studied yet. 3,772 people, all under 50, were included in this study, their full data came from National...

Abstract Eye-to-hand calibration is an essential technique for achieving precise alignment between vision sensors and robot control systems, it widely recognized its significance in the effective implementation of vision-guided robots advanced manufacturing. However, traditional eye-to-hand often faces challenges attaining high precision hand-eye matrix estimation within industrial applications. These arise from absolute positioning errors robots, complications related to parameter...

Artificial Intelligence (AI) Machine Learning (ML) technologies, particularly Deep (DL), have demonstrated significant potential in the interpretation of Remote Sensing (RS) imagery, covering tasks such as scene classification, object detection, land-cover/land-use change and multi-view stereo reconstruction. Large-scale training samples are essential for ML/DL models to achieve optimal performance. However, current organization is ad-hoc vendor-specific, lacking an integrated approach that...

Background Cardiovascular disease (CVD) poses a significant global health and economic challenge, with atherosclerosis being primary cause. Over the past 40 years, substantial research has been conducted into prevention reversal of atherosclerosis, resulting in development lipid-lowering agents such as statins fibrates. Despite extensive literature formulation numerous therapeutic guidelines this domain, comprehensive bibliometric analysis current landscape trends not performed. This study...

In software development, stakeholders of the same project often collaborate asynchronously through shared artifacts. A traceability system links a project's artifacts and therefore provides support for collaboration among stakeholders. Different are interested in different types links. The literature states that is useful but expensive to build maintain. However, there no study showing reduction effort when various provided used during maintenance phase. This paper presents evaluating...

Using the principles of fluid mechanics for flow around objects, a three dimensional (3D) path planning method unmanned aerial vehicles (UAVs) in complex environments is studied. As potential field method, it theoretically guarantees to avoid local minima with smooth paths and modeling environment simple. First, an analytical solution derived determine steady 3D acting on single spherical obstacle. Subsequently, interpolation function introduced multiple obstacles avoidance. Finally,...

A 3-D dynamic path-planning algorithm based on interfered fluid flow (DA) is proposed for unmanned aerial vehicle (UAV) in environment. This paper first describes the mathematical modeling of convex obstacles. Then static (SA) introduced and improved, whose planning path conforms to general characteristic phenomenon that running water can avoid rock arrive at destination. By updating information obstacles obtaining relative velocity, we then transform problem problem. Therefore, DA...

A robust ellipse detector is proposed. The preprocesses the edge map by removing all isolated points and conjunction points, exploits polygonal curve to extract elliptical arcs. non‐iterative geometric distance computation method presented serve a criterion which identifies arcs belonging same likelihood ratio test fit ellipses those merged authors their algorithm on both synthetic real images, experimental results show good performance of algorithm.

Conventionally, wavelength‐selective ultraviolet photodetection is achieved by using broadband inorganic photodiodes coupled with optical filters, which significantly increases the complexity and fabricating cost of devices for high pixel density imaging systems. Here, a facile approach to achieve tunable spectral response without filters demonstrated. The are based on ZnO heterojunctions, spectra effectively modulated tuning position charge generation, results in distinct charge‐collection...

The aim of the present study was to screen differentially expressed miRNAs in vulvar squamous cell carcinoma (VSCC), observe role microRNA‑4712‑5p VSCC and investigate its targets regulatory mechanism. Differentially human tissues were screened. selected expression level verified clinical tissue samples line A431 by reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) analysis. overexpression vector prepared transfected into cells; subsequently, invasion metastasis examined...

We report on the fabrication of hollow and sandwiched nanoparticles by ion irradiation. Ag embedded in silica were irradiated N+, Si+, Ar+, Cu+ ions at 300keV to a fluence 5×1016ions∕cm2, varying energies from 110to500keV 400keV fluences varied 1×1016to1×1017ions∕cm2.
