This survey data is from a study exploring the potential to promote lower-emissions air travel by providing consumers with information about the carbon emissions of possible flight choices in the context of online flight search and booking. We surveyed over 450 faculty, researchers, and staff at the University of California, Davis, and asked them to choose among hypothetical flight options for a domestic and an international university-related business trip. Emissions estimates for different flight alternatives were displayed as prominently as price; this simple intervention has been promoted in several demonstration projects, including GreenFLY, a demo we created at UC Davis.
Methods The flight choice experiment involved an online survey in which UC Davis employees were asked to make a series of binary discrete choices between roundtrip flight alternatives, that varied in terms of cost, carbon emissions, layovers (0 or 2: one layover each way), and airport (SMF or SFO), for two hypothetical UC Davis-related business trips, one to Washington, DC and the other to London. We based these hypothetical scenarios (trip destinations and attribute levels of flight alternatives) on data about actual UC Davis employee air travel.
For the layover flight alternatives, we created eight possible cost-carbon combinations, using each cost level and each carbon level twice, and not repeating any pairing. There are many ways to do this, and we chose one which tended to pair high cost with low carbon, to create trade-offs. Our eight layover flights to DC appear in Table 2. The same cost-carbon pairings were used for layover flight alternatives from SFO.
We organized the flight alternatives into sets of two for the choice experiment questions. Criteria for pairing flight alternatives were as follows: 1. Every flight alternative should appear roughly the same number of times in the survey, 2. The distribution of kinds of flights in the questions (eg. layover out of SFO) should match the distribution in the entire set, 3. Avoid questions in which the two flights have the same cost, or the same carbon, and 4. Focus on pairs that might have competitive utility (e.g. an alternative that is lower cost, lower carbon, nonstop and out of SMF is likely to be selected in most cases, so it is not useful for understanding potential trade-offs).
From this, we created seven "buckets" of questions for Washington, and seven for London, and asked each participant a randomly-chosen question from each bucket. We made an error in the online questionnaire-design software, which caused a random bucket to be skipped for London. Nonetheless, each flight option appears freqently (between 40 and 120 times) in the questions we asked.
The original data output from Qualtrics was processed into a format suitable for processing with the mlogit package in R.

The "Bangladesh Flight Fare Dataset" is a synthetic dataset comprising 57,000 flight records tailored to represent air travel scenarios originating from Bangladesh. This dataset simulates realistic flight fare dynamics, capturing key factors such as airline operations, airport specifics, travel classes, booking behaviors, and seasonal variations specific to Bangladesh’s aviation market. It is designed for researchers, data scientists, and analysts interested in flight fare prediction, travel pattern analysis, or machine learning/deep learning applications. By combining real-world inspired statistical distributions and aviation industry standards, this dataset provides a robust foundation for exploring flight economics in a South Asian context.
This dataset aims to: - Facilitate predictive modeling of flight fares, with "Total Fare (BDT)" as the primary target variable. - Enable analysis of travel trends, including the impact of cultural festivals (e.g., Eid, Hajj) and booking timings on pricing. - Serve as a training resource for machine learning (ML) and deep learning (DL) models, with sufficient sample size (50,000) and feature diversity for generalization. - Provide a realistic yet synthetic representation of Bangladesh’s air travel ecosystem, blending domestic and international flight scenarios.
The dataset is synthetically generated using Python, with its methodology rooted in real-world aviation data and statistical principles. Below is a detailed breakdown of its construction:

Clearwing moths are known for their physical resemblance to hymenopterans, but the extent of their behavioural mimicry is unknown. We describe zigzag flights of sesiid bee mimics which are nearly indistinguishable from those of sympatric bees, whereas sesiid wasp mimics display faster, straighter flights more akin to those of wasps. In particular, the flight of the sesiids Heterosphecia pahangensis, Aschistophleps argentifasciata and Pyrophleps cruentata resembles both Tetragonilla collina and T. atripes stingless bees and, to a lesser extent, dwarf honey bees Apis andreniformis, whereas the sesiid Pyrophleps sp. resembles Tachysphex sp. wasps. These findings represent the first experimental evidence for behavioural mimicry in clearwing moths.

Due to the rapid aging of bridges in Japan, there is a need for an advance and more reliable structural health monitoring techniques. This study conducted an unmanned aerial vehicle (UAV) semi-autopilot path flight controlled method by utilizing the DJI Software Development Kit (SDK) for inspection of Global Navigation Satelite System (GNSS)-denied parts of a bridge specifically in-between girders and other semi- closed and narrow areas. A mini- UAV’s path planning was pre-programmed under a known environment using waypoints and python programming language. A miniature low cost camera was attached as a payload and captured the images underneath the bridge deck aside from the captured images along the line of sight of the UAV. The UAV test flight was done in a pedestrian bridge located at Saitama University. The UAV successfully inspected underneath the bridge deck and some narrow parts in semi-autopilot mode. After that, corrosion, spalling, and crack damages were detected using two different vision based deep learning methods, YOLOv3 and Mask R-CNN. In addition, since the flight path plan was pre- programmed by measured commands, the location of the captured damages were easily located. To visualize the damage location, a 3D model underneath the decks was generated using structure from motion (SfM) and open sourced softwares. Due to the UAV’s small size and the ability to have a semi-autopilot controlled flight path, it eliminated the GNSS dependent problem in bridge damage inspection and been able to inspect narrow areas which were difficult to access. The combination of semi-autopilot inspection under gps-denied parts of bridge inspection, damage detection, and 3D model construction were the main focus of this research.

Flying insects often forage among cluttered vegetation that forms a series of obstacles in their flight path. Recent studies have focused on behaviors needed to navigate clutter while avoiding all physical contact, and as a result, we know little about flight behaviors that do involve encounters with obstacles. Here, we challenged carpenter bees (Xylocopa varipuncta) to fly through narrow gaps in an obstacle course to determine the kinds of obstacle encounters they experience, as well as the consequences for flight performance. We observed three kinds of encounters: leg, body, and wing collisions. Wing collisions occurred most frequently (in about 40% of flights, up to 25 times per flight) but these had little effect on flight speed or body orientation. In contrast, body and leg collisions, which each occurred in about 20% of flights (1-2 times per flight), resulted in decreased flight speeds and increased rates of body rotation (yaw). Wing and body collisions, but not leg collisions, were more likely to occur in wind versus still air. Thus, physical encounters with obstacles may be a frequent occurrence for insects flying in some environments, and the immediate effects of these encounters on flight performance depend on the body part involved. Methods Freely flying female carpenter bees (Xylocopa varipuncta, n = 15) were collected from the University of California, Davis campus and subjected to flight challenges in a laboratory flight tunnel. Individual bees were placed in the flight tunnel (20 x 19 x 115 cm; width x height x length), which included a series of vertical columns (hereafter ‘obstacles’) that spanned the middle of the tunnel (obstacle diameter = 7 mm, space between obstacles = 34.44 ± 2.80 mm; mean ± SD). The bees’ wing spans (45.19 ± 2.11 mm, from tip to tip) were larger than the size of the gaps between obstacles; thus, bees could not fly straight through gaps, but instead needed to rotate their body (e.g., yaw) in order to pass through. Obstacles were attached to a mechanical arm that oscillated laterally (amplitude = 21 mm, frequency = 2 Hz) or remained stationary. Fans at each end of the tunnel could be turned on to produce a gentle breeze (mean velocity = 0.54 m/s) or off for still air. Wind direction was constant: bees flying in one direction experienced headwinds and in the other direction tailwinds. Up to 12 flights through the obstacles were elicited from each bee, using full spectrum lights that were alternately turned on and off at each end of the tunnel. Obstacle motion (stationary versus oscillating) was fixed for a given bee, but all bees experienced both wind and still air, with the order of the wind condition switched after approximately six flights. Thus, four different flight conditions were tested on the group of bees: still air with stationary obstacles (n = 40 flights), still air with oscillating obstacles (n = 34), wind with stationary obstacles (n = 42), and wind with oscillating obstacles (n = 29). Flights were filmed with two synchronized Phantom v611 cameras (Vision Research, Inc., Wayne, NJ, USA) sampling at 1500 frames/s and positioned 30º from the vertical on opposite sides of the obstacles. Cameras were calibrated using a standard checkerboard calibration method and built-in MATLAB functions. In each video, the positions of the bee’s head (midpoint between antennae), thorax (approximating the body centroid), and wing tips were tracked with the machine-learning software DeepLabCut. Tracked points were checked and manually corrected, and obstacle positions were labeled using DLTdv6 in MATLAB. Labeled positions were converted from two-dimensional coordinates in each camera view into three-dimensional space using built-in MATLAB functions. We classified and counted each physical encounter that occurred between the bees and obstacles. The most common encounters were body collisions (the head, thorax, or abdomen contacted the obstacles), leg collisions (one or more forelegs contacted the obstacles), and wing collisions (the distal half of one or more forewings contacted the obstacles).
We next assessed how encounters with obstacles affected flight performance. In each video, we identified the first occurrence of each body, leg, and wing collision, and defined a 20-ms period before and after each encounter. This temporal window allows us to quantify performance immediately before and after obstacle encounters, as in, to determine how flight performance changes during encounters. Some of these pre- and post-encounter periods contained additional collisions with obstacles, but they were included in the analysis to reflect the true nature of flight in clutter (i.e., flights with just one obstacle encounter were rare). From this analysis, videos yielded either a single encounter type (n = 42 flights), two encounter types (n = 26), or all three encounter types (n = 9). For each encounter, we measured the change in horizontal ground speed and yaw between the pre- and post-collision periods, as well as the post-collision yaw rate, where yaw was the body angle about the vertical axis. To calculate kinematics, we smoothed the three-dimensional position data with cubic smoothing spline curves via the ‘smooth.spline’ function in the R package stats. Horizontal ground speed was calculated as the change in x-y position (lateral and longitudinal motions, omitting vertical motion) per time. Yaw was calculated by converting the Cartesian coordinates of the head and thorax to spherical coordinates via the ‘cart2sph’ function in the R package pracma and finding the horizontal angle between the two body points and the long axis of the tunnel. The yaw rate was calculated over the 20 ms post-collision by taking the derivative of yaw with respect to time.
