Abstract:
One of the most application of the directional drilling is drilling multiple wells from one location or platform. In drilling multiple wells from one location the major problem that faced is avoiding the collision with the offset wells that drilled near the proposed well in the same region. Therefore, the Potential of Collison between the wells can cause severe catastrophic accidents such as an explosion or oil spill. Several measurements of proximity calculation or methods have been adopted to control the distance between the wells, avoid the Collison, increas-ing the clearance along with smoothing the trajectory, Reducing the drilling time based on the anti-collision rules. A real case study of an offshore directional horizontal well drilled from the platform is studied through the paper. The proposed well is drilled in the neighboring of three Offset wells that should be Planned completely to avoid the Collison with them. The well is planned through an advanced anti-collision method that results in preventing the collision of well with optimized drilling performance through Oriented separation factor (OSF). This factor yields appropriate separation with OSF greater than 5. This yield efficient separation with offset well 1, offset well 2 and offset well 3 greater thant5, In addition to optimized drilling performance of 84% drilling versus 16% sliding that results in the completion of the well in 50 days with positive income that result in 8.55 Return on Investment (ROI).

Abstract:
Flocculation is described by the Smoluchowski equation. Two-particle collisions are considered to occur by Brownian motion, fluid motion (shear), and differential sedimentation. In its original form, the Smoluchowski equation incorporated a rectilinear view of collisions, i.e., a view that ignored the effects of hydrodynamics and van der Waals attraction on particle collisions. A comparison between experimental results for heterodisperse suspensions and predictions of the rectilinear model of flocculation suggests strongly that the model overpredicts the collison frequency between large and small particles. Two methods that correct this problem are explored in this paper. First, a view of collisions in turbulent flow is presented; in this view the applicable velocity gradient that influences the collision frequency for fluid motion is a decreasing function of particle size. This approach is relatively new and somewhat unproven, but does have a basis in turbulence theory. Second, a curvilinear view of collisions that does account for hydrodynamic interactions and van der Waals attraction is considered; this approach, well-founded in theory developed by others, leads to a dramatic reduction in the predicted collision frequency between large and small particles.

Abstract:
ABSTRACT The deposition patterns of large-particle microbiological aerosols within the respiratory tract are not well characterized. A novel system (the flow-focusing aerosol generator [FFAG]) which enables the generation of large (>10-μm) aerosol particles containing microorganisms under laboratory conditions was characterized to permit determination of deposition profiles within the murine respiratory tract. Unlike other systems for generating large aerosol particles, the FFAG is compatible with microbiological containment and the inhalational challenge of animals. By use of entrapped Escherichia coli cells, Bacillus atrophaeus spores, or FluoSphere beads, the properties of aerosols generated by the FFAG were compared with the properties of aerosols generated using the commonly available Collison nebulizer, which preferentially generates small (1- to 3-μm) aerosol particles. More entrapped particulates (15.9- to 19.2-fold) were incorporated into 9- to 17-μm particles generated by the FFAG than by the Collison nebulizer. The 1- to 3-μm particles generated by the Collison nebulizer were more likely to contain a particulate than those generated by the FFAG. E. coli cells aerosolized using the FFAG survived better than those aerosolized using the Collison nebulizer. Aerosols generated by the Collison nebulizer and the FFAG preferentially deposited in the lungs and nasal passages of the murine respiratory tract, respectively. However, significant deposition of material also occurred in the gastrointestinal tract after inhalation of both the small (89.7%)- and large (61.5%)-particle aerosols. The aerosols generated by the Collison nebulizer and the FFAG differ with respect to mass distribution, distribution of the entrapped particulates, bacterial survival, and deposition within the murine respiratory tract.

Abstract:
The first measurements of the transverse momentum (pT) spectra and integrated yields of Σ0 and Σ−0 baryons in proton-proton (pp) collisions at √s = 7 TeV are reported. The Σ0(Σ−0) signal is reconstructed via the Λ (Λ−) + γ decay channel by invariant mass analysis. The Λ (Λ−) baryon is reconstructed by its weak decay into p + π−(p− + π+), while the photon is detected exploiting the unique capability of the ALICE detector to measure low energy photons via conversion into e+e− pairs. A significant disagreement between the data and the predictions from the QCD-inspired Monte Carlo event generator PYTHIA is observed for the pT spectrum. The yield ratio of Σ0(Σ−0) to Λ is shown as a function of pT . Finally, the new data point for the integrated yield ratio of Σ0(Σ−0) to Λ from pp collisions at 7 TeV is found to be similar to the results obtained in different elementary collison systems (e+e−, pp) measured at collision energies below 100 GeV.

Abstract:
NSF International Standard 49–1992, that covers certification of biological safety cabinets, makes “special note” that a “stainless steel 6-jet Collison refluxing nebulizer will deliver the [required] bacterial spore aerosol” when certain stated conditions are met and “need not be retested for performance before use” (Appendix-C, page C1) (1). The basis on which this nebulizer was vetted was presented at the XXV Biological Safety Conference (Boston, MA, 1984) but never published in the open literature. In view of the importance of this device for the procedures used to certify the performance of biological safety cabinets, the authors are of the opinion that the test protocols and test data on which the selection was based should be made a matter of record. Collison nozzle studies were conducted to determine (a) whether all 6 Collison nozzles manufactured by BGI give the same spore output when operated at 140 kPa (20 psig) with an equal number spore suspension in the flask (b) whether spore delivery by the 6-jet Collison nozzle equals or exceeds the minimum number specified by NSF 49 when charged with the recommended spore suspension (c) whether performance of Collison nozzles with a bacterial spore aerolsol can be predicted accurately with a monodisperse 1.1 μm polystyrene latex spherical simulant, and (d) the optimum nebulizer flask geometry.

Abstract:
Collison tumor of the stomach is rare, and its endoscopic and pathological features remain poorly described. A 70-year-old woman was referred to our hospital for examination and treatment of undifferentiated gastric cancer. Esophagogastroduodenoscopy revealed a whitish, superficial elevated lesion in contact with a reddish, superficial depressed lesion from the anterior wall of the gastric angle and antrum to the lesser curvature. Laparoscopic distal gastrectomy was performed for preoperative diagnosis of suspected early gastric cancer presenting as a differentiated and undifferentiated collision tumor, which led to the lesion being diagnosed as collision tumor, tub1-tub2+por1-sig, pT1a (M), ly0, v0, N0, stage IA. To our knowledge, this report represents a valuable addition to the collision tumor literature describing a rare case of preoperatively diagnosed collision tumor of the stomach.

Abstract:
This study will examine the impact of economic collision on the non-performing financing in sharia bank in Indonesia. The current study adopts VAR/VECM method to examine inter variables correlation by testing an economic factors, including 1) Real GDP Growth, 2) Exchange Rate, 3) Inflation, 4) Interest Rate, and 5) IDX Composite. A total NPF of 14 Islamic Banks and 20 Sharia Business Units were selected as data samples from 2006 to 2020. The findings indicate that inflation positively impacts NPF in the short run and delivers the biggest shock to NPF. The result states that Inflation, Exchange rate, and Interest rate are the dominant factors to shock NPF in Islamic Banks. From the analysis results, the economic variables, i.e., GDP, exchange rates, inflation, interest rates, and the IDX Composite, provide a stable long-term relationship and, in the short term, adjust to each other to achieve a new balance in the long term.

Abstract:
This thesis considers two types of applications of quantum feedback control; feedback creation of nonclassical states of light, and controlling nonclassical properties of an ensemble of atoms. An electro-optical feedback loop will create an in-loop field with nonclassical photon statistics similar to squeezed light, resulting in fluorescence line-narrowing of a two-level atom coupled to such light. We extend this theory to study a three-level atom coupled to broadband squashed light, and confirm the two-level atom line-narrowing using a more realistic non-Markovian description of the feedback loop. The second type of application utilizes continuous QND measurement of atomic ensembles. If we measure the collective spin, then the system experiences conditional spin squeezing dependent on the measurement results. We show that feedback based on these results can continuously drive the system into the same conditioned state, resulting in deterministically reproducible spin squeezing. If we measure the atom number fluctuations of a BEC, then, due to the nonlinearity of atomic self interactions, this is also information about phase fluctuations. We show that feedback based on this information can greatly reduce the collisional broadening of the linewidth of an atom laser out-coupled from the condensate.

Abstract:
One Colour-Resonant Two-Photon Ionisation, coupled with a supersonic expansion was used to study the rotationally cold excited electronic states of the water clusters of ortho-, meta- and para-difluorobenzene. Ground state rotational constants obtained through ab-initio calculations allowed rotational band contour simulations of these species to be performed, elucidating structural and spectroscopic features such as rotational band types, directions of transition dipole moments and excited state geometries. Confidence in the calculated ground state geometries, obtained through successful simulation of the rotational band contours, provided strength to the credibility of the vibrational frequencies acquired via these calculations. Analysis of ground state dispersed fluorescence spectroscopy utilising these ab-initio (geometry + frequency) optimisation calculations, allowed assignment of the ground state vibrational modes of each species. Furthermore, comparison of the assigned ground state modes with the excited state spectroscopy, affirmed assignment of the low frequency Van der Waals modes along with the higher frequency aromatic ring modes of these cluster species. A novel technique that produces pseudo-selective excitation of ground state aromatic-rare gas cluster ions was used to assign the vibrational transitions of the D3[less than]D0 electronic excitation spectrum of para-Difluorobenzene+-Argonn=1,2. This technique works on the principle of providing varying degrees of excess energy to the ground state of the cluster ion, as well as altering the Franck-Condon factors for excitation to the D3 electronic state. Measurement of the redshifts for each pDFB-R (where R= Ar1, Ar2, Kr1, Kr2) cluster, revealed that the addition of a second rare-gas adatom doubled the redshift, and that Krypton ad-atoms produced a stronger redshift than argon as expected. It was also noted that the addition of a positive charge to the complex increased the redshift of the complexes, in accordance with our expectations. Rotational state-resolved differential cross sections (DCS's) for rotationally inelastic collisions of HCl with Ne, Ar, and Kr at ~545, ~538, and ~526 cm-1 of collision energy, respectively, were measured using velocity-mapped ion imaging. For each rotational state, the observed DCS's were found to be qualitatively similar. As collider mass was increased, the differential cross section became increasingly forward scattered. Calculations suggest that much of this difference is due to kinematic effects, but that the potential energy surface should be slightly more anisotropic for heavier colliders.

Abstract:
Purpose – The purpose of the study is to expand the knowledge of how wheel motor currents can be combined with machine learning to be used in a collision detection system for autonomous robots, in order to decrease the number of external sensors and open new design opportunities and lowering production costs. Method – The study is conducted with design science research where two artefacts are developed in a cooperation with Globe Tools Group. The artefacts are evaluated in how they categorize data given by an autonomous robot in the two categories collision and non-collision. The artefacts are then tested by generated data to analyse their ability to categorize. Findings – Both artefacts showed a 100 % accuracy in detecting the collisions in the given data by the autonomous robot. In the second part of the experiment the artefacts show that they have different decision boundaries in how they categorize the data, which will make them useful in different applications. Implications – The study contributes to an expanding knowledge in how machine learning and wheel motor currents can be used in a collision detection system. The results can lead to lowering production costs and opening new design opportunities. Limitations – The data used in the study is gathered by an autonomous robot which only did frontal collisions on an artificial lawn. Keywords – Machine learning, K-Nearest Neighbour, Multilayer Perceptron, collision detection, autonomous robots, Collison detection based on current.
Syfte – Studiens syfte är att utöka kunskapen om hur hjulmotorstömmar kan kombineras med maskininlärning för att användas vid kollisionsdetektion hos autonoma robotar, detta för att kunna minska antalet krävda externa sensorer hos dessa robotar och på så sätt öppna upp design möjligheter samt minska produktionskostnader Metod – Studien genomfördes med design science research där två artefakter utvecklades i samarbete med Globe Tools Group. Artefakterna utvärderades sedan i hur de kategoriserade kollisioner utifrån en given datamängd som genererades från en autonom gräsklippare. Studiens experiment introducerade sedan in data som inte ingick i samma datamängd för att se hur metoderna kategoriserade detta. Resultat – Artefakterna klarade med 100% noggrannhet att detektera kollisioner i den giva datamängden som genererades. Dock har de två olika artefakterna olika beslutsregioner i hur de kategoriserar datamängderna till kollision samt icke-kollisioner, vilket kan ge dom olika användningsområden Implikationer – Examensarbetet bidrar till en ökad kunskap om hur maskininlärning och hjulmotorströmmar kan användas i ett kollisionsdetekteringssystem. Studiens resultat kan bidra till minskade kostnader i produktion samt nya design möjligheter Begränsningar – Datamängden som användes i studien samlades endast in av en autonom gräsklippare som gjorde frontalkrockar med underlaget konstgräs. Nyckelord – Maskininlärning, K-nearest neighbor, Multi-layer perceptron, kollisionsdetektion, autonoma robotar

Abstract:
AbstractThe complexity of binary droplet collisions strongly increases in case of immiscible liquids with the occurrence of triple lines or for high energetic collisions, where strong rim instabilities lead to the spattering of satellite droplets. To cope with such cases, the Volume of Fluid method is extended by an efficient interface reconstruction, also applicable to multi-material cells of arbitrary configuration, as well as an enhanced continuous surface stress model for accurate surface force computations, also applicable to thin films. For collisions of fully wetting liquids, excellent agreement to experimental data is achieved in different collision regimes. High-resolution simulations predict droplet collisions in the spattering regime and provide detailed insights into the evolution of the rim instability. Another challenge is the numerical prediction of the collision outcome in the bouncing or coalescence region, where the rarefied gas dynamics in the thin gas film determines the collision result. To this end, an important step forward became possible by modelling the pressure in the gas film. With the introduction of an interior collision plane within the flow domain, it is now possible to simulate droplet collisions with gas film thickness reaching the physically relevant length scale.

Abstract:
Robert Denis Collison Black was internationally recognized as the authority on Jevons, and in particular on the centrally important elements of Benthamite Utilitarianism in Jevons' thought. Jevons' Theory Political Economy was, Black argued, a Benthamite exercise, not a systematic treatise on value and distribution. This in turn explained why Jevons' theory of production was essentially classical, and why he had no theory of aggregate distribution. Black's work on Jevons also threw light on the professionalization of economics. Black was the well-merited recipient of many honours. In 1974 he was elected both a Fellow of the British Academy and a Member of the Royal Irish Academy. He became an Honorary Fellow of Trinity College, Dublin in 1982; President of the Statistical and Social Inquiry Society of Ireland over the years 1983 to 1986; acted as President of Section F of the British Association in 1984–5; was elected a Distinguished Fellow of the History of Economics Society in 1987; and in 1988, Queen's University bestowed upon him an Hon. D.Sc. Econ.

Abstract:
People love to fly drones, but unfortunately many end up crashing or losing them. As the technology of flying drones improves, more people are getting involved. With the number of users increasing, people find that flying drones with sensors is safer because it can automatically avoid problems, but such drones are expensive. This paper describes an inexpensive UAV (unmanned aerial vehicle) system that eliminates the need for sensors and uses only the camera to avoid collisions. This program helps avoid drone crashes and losses. We used the Tello Education drone as our testing drone, which is only outfitted with a camera. Using the camera feed and transmitting that data to the program, the program will then give commands to the drone to avoid collisions.

Abstract:
E-scooter use is increasing, and with it, the number of collisions involving e-scooters. The rapid rate of uptake of devices has resulted in a gap in the reference data available for collision investigators to make use of in reconstructing collisions, data which is commonly available for other collision types. The main aim of this study was to consider the capabilities of privately owned devices likely to be encountered in ‘real world’ collision scenarios and examine whether manufacturer-published data is realistic. Common characteristics and observations relevant to collision investigations were also recorded. A sample of donated, used devices was tested to determine the acceleration, deceleration and peak speed characteristics of different types of device

Abstract:
This study looks at the patterns and processes of elk-vehicle collisions in the Central Canadian Rocky Mountains and analyses the demographic structure of the wildlife involved in the collisions. Key findings included: males and subadults were more prone to elk-vehicle collisions; collisions occur more commonly in the fall season; all healthy elk are susceptible to vehicle collisions; the magnitude of elk collision was negatively correlated to traffic volumes, because abundance of elk greatly decreased during the study period; and elk abundance was the primary driver influencing occurrence of collisions over time. Collectively, these results will help inform the design of mitigation measures targeting the most vulnerable demographics of a population, i.e. subadults and male elk in the fall.

Full text
Abstract:
Wildlife exclusion fencing has become a standard component of highway mitigation systems designing to reduce collisions with large mammals. Past work on the effectiveness of exclusion fencing has relied heavily on control-impact (i.e., space-for-time substitutions) and before-after study designs. These designs limit inference and may confound the effectiveness of mitigation with co-occurring process that also change the rate of collisions. We used a replicated before-after-control-impact study design to assess fencing effectiveness along the Trans-Canada Highway in the Rocky Mountains of Canada. We found that collisions declined for common ungulates species (elk, mule deer and white-tailed deer) by up to 96% but not for large carnivores. The weak response of carnivores is likely due to combination of fence intrusions and low sample sizes. When accounting for background changes in collision rates observed at control sites, naïve estimates of fencing effectiveness declined by 6% at one site to 90% and increased by 10% at another to a realized effectiveness of 82%. When factoring in the cost of ungulate collisions to society as a whole, fencing provided a net economic gain within 1 year of construction. Over a 10-year period, fencing would provide a net economic gain of >$500,000 per km in reduced collisions. In contrast, control site may take upwards of 90 years before the background rates of collisions decline to a break even point. Our study highlights the benefits of long-term monitoring of road mitigation projects and provides evidence of fencing effectiveness for reducing wildlife-vehicle collisions involving large mammals.

Abstract:
This document is a task report for a larger Wildlife Vehicle Collision (WVC) Reduction and Habitat Connectivity pooled fund study. It addresses the potential use of passive use economic values for wildlife to inform the mitigation of wildlife-vehicle collisions. Passive use, also known as non-use values, are the values individuals place on the existence of a given animal species or population as well as the bequest value of knowing that future generations will also benefit from preserving the species. This report describes a pilot survey and study of willingness to pay by Minnesota households to pay for exclusionary fencing and passage structures to reduce vehicle/animal collisions in the state. The species of focus were deer and turtles. The study found strong support for fencing and passage structures, and statistically significant willingness to pay increased taxes to support their construction.

This report provides a summary of the current literature of wildlife passive use value estimates and provides per-animal passive use values for selected species and populations. Additionally, an example of applying these values to a Montana road segment is outlined. Finally, a discussion of regional economic impacts of mitigation structure spending is outlined.

Full text
Abstract:
This report contains an update and an expansion of a cost-benefit model for wildlife-vehicle collisions and associated mitigation measures along highways, that was originally calculated in 2007 US$ and published in 2009. The direct cost values (vehicle repair, human injuries, human fatalities) were updated for deer, elk, and moose, and expanded by including additional species: gray wolf (Canis lupus), grizzly bear (Ursus arctos), and free ranging or feral domesticated species including cattle, horse, and burro. The costs associated with collisions were also expanded by including passive use, or nonuse values associated with the conservation value of selected wild animal species. The total costs (in 2020 US$) associated with a collision with deer, elk and moose were about 2-3 times (direct costs only) or about 3-4 times higher (direct costs and passive use values combined) compared to the values in 2007 US$. The passive use costs associated with threatened species (wolf, grizzly bear) were higher or much higher than the direct costs. The costs associated with mitigation measures (especially fences and wildlife crossing structures) were also updated and supplemented with new data. New cost-benefit analyses generated updated or entirely new threshold values for deer, elk, moose, and grizzly bear. If collisions with these large wild mammal species reach or surpass the threshold values, it is economically defensible to install the associated type and combination of mitigation measures, both based on direct use and passive use parameters and their associated values. The trend in increasing costs associated with vehicle repair costs, costs associated with human injuries and fatalities, and through including passive use values for wildlife is that we learn that the implementation of effective mitigation measures can be considered earlier and more readily than based on the cost-benefit model published in 2009.
