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).

Streszczenie:

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 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.

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.

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.

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.

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.

Our ROSAT observations of γ Velorum obtained over several binary cycles reveal substantial, and repeatable phase-dependent X-ray (0.1—2.5 keV) variations. The derived X-ray light-curve shows a 4 x increase in flux at phase ∼ 0.5, which is shown to arise in shocked gas formed in the collison of the two stellar winds, viewed through a cavity in the WC8 wind with an observed opening angle of ∼ 50°. This colliding-wind X-ray emission has Lx ≥ 1032 ergs−1 and kT ≥ 2 keV. Our 2-D hydrodynamical models of the system predict copious X-ray emission from the wind-collision region, at a level and spectrum similar to that observed. Harder (1—10 kev) X-ray observations with the ASCA satellite are being sought to provide improved constraints on the luminosity, spectrum and absorption of the wind-collision emission, and the complex theoretical models involved.

Abstract: The future of automotive relies on the mechatronic and electronic systems. The worldwide growth of automotive towards electronic systems suggests that driverless cars would soon be the common commuters. With such improvements safety of the passengers becomes first priority for the manufacturers. Nowadays automobiles come with high end technologies and quick responsive electronic systems. In addition to the passive safety systems, active safety systems definitely avoid collision thereby reducing the chances of injury and death. This project shows the working of an active safety system that is collision avoidance system. To create the model, TINKERCAD software has been used and a detailed working is explained. As a result, the system detects traffic and can alert the driver and stop the vehicle before meeting the collision. Keywords: Active Safety System, Arduino, Tinkercad, Vehicle Electronics System, Automotive Safety System, Collision Avoidance System, Self-Driving Car, Driverless Vehicle.

Collision phenomena are very fast and nonlinear, thus, it is difficult to control a manipulator by collision phenomena. Therefore, in the past, manipulators moved slowly in order to avoid collision. However, the need for high-speed operation has been increasing, making it is indispensable to control manipulators by collision phenomena. With such fast phenomena, it is effective to use learning control in a forward manner. In this paper, we have proposed a learning control method to optimize the weighted least-squares criterion of learning errors. This method is applied in order to obtain a unique control gain by the Riccati equation which has a state dimension equal to the sampling number. It is shown that the convergence of learning error can be readily assured because the present learning rule consists of a steadystate Kalman filter. Based on this learning control method, experimental results of force control with a collision phenomena are reported.

Damage to bridge structures caused by vessel collision is a risk for bridges crossing water traffic routes. Therefore, safety around vessel collision of existing and planned bridges is one of the key technical problems that must be solved by engineering technicians and bridge managers. In the evaluation of the reliability of the bridge structure, the two aspects of vessel-bridge collision force and structural resistance need to be considered. As there are many influencing parameters, the performance function is difficult to express by explicit function. This paper combines the moment method theory of structural reliability with finite element analysis and proposes a statistical moment method based on finite element analysis for the calculation of vessel-bridge collision reliability, which solves the structural reliability problem with a nonlinear implicit performance function. According to the probability model based on current velocity, vessel velocity, and vessel collision tonnage, the estimate points in the standard normal space are converted into estimate points in the original state space through the Rosenblatt reverse transform. According to the estimate points in the original state space and the simplified dynamic load model of vessel-bridge collision, the sample time-history curve of random vessel-bridge collision force is generated, the dynamic response of the bridge structure and the structural resistance of the bridge are calculated by establishing a finite element model, and the failure probability and reliability index of the bridge structure is calculated according to the fourth-moment method. The statistical moment based on the finite element analysis is based on the finite element analysis and the moment method theory of structural reliability. The statistical moment of the limited performance function is calculated through a quite small amount of confirmatory finite element analysis, and the structural reliability index and failure probability are obtained. The method can be widely used in existing finite element analysis programs, greatly reducing the number of finite element analyses needed and improving the efficiency of structural reliability analysis.

ABSTRACTWe report here that stress experienced by bacteria due to aerosolization and air sampling can result in severe membrane impairment, leading to the release of DNA as free molecules.Escherichia coliandBacillus atrophaeusbacteria were aerosolized and then either collected directly into liquid or collected using other collection media and then transferred into liquid. The amount of DNA released was quantified as the cell membrane damage index (ID), i.e., the number of 16S rRNA gene copies in the supernatant liquid relative to the total number in the bioaerosol sample. During aerosolization by a Collison nebulizer, theIDofE. coliandB. atrophaeusin the nebulizer suspension gradually increased during 60 min of continuous aerosolization. We found that theIDof bacteria during aerosolization was statistically significantly affected by the material of the Collison jar (glass > polycarbonate;P< 0.001) and by the bacterial species (E. coli>B. atrophaeus;P< 0.001). WhenE. coliwas collected for 5 min by filtration, impaction, and impingement, itsIDvalues were within the following ranges: 0.051 to 0.085, 0.16 to 0.37, and 0.068 to 0.23, respectively; when it was collected by electrostatic precipitation, theIDvalues (0.011 to 0.034) were significantly lower (P< 0.05) than those with other sampling methods. Air samples collected inside an equine facility for 2 h by filtration and impingement exhibitedIDvalues in the range of 0.30 to 0.54. The data indicate that the amount of cell damage during bioaerosol sampling and the resulting release of DNA can be substantial and that this should be taken into account when analyzing bioaerosol samples.

AbstractThis study examines a little-known case of Enlightenment knowledge transmission centred on the rock-cut monument of Darius I at Bīsotūn in western Iran. It discusses a report on the monument published by the cartographer and historian Jean-Baptiste Bourguignon d'Anville, which originated with the Decalced Carmelite monk Emmanuel de Saint-Albert (born Jean-Claude Ballyet); who transmitted it to Isaac Bellet, a doctor involved in secret negotiations in Constantinople; who in turn sent it to Louis, Duke d'Orléans, in Paris; who passed it on to d'Anville. The collison of scholarly interest, political service and scientific personality offers a fascinating case study of the Enlightenment ‘republic of letters’ in action.

Abstract The present research study aims at analysing the kinematic and the dynamic behaviour of the vehicle’s driver in a frontal collision. Hence, a subsequent objective of the research paper is to establish the degree of injury suffered by the driver. Therefore, in order to achieve the objectives set, first, we had to define the type of the dummy placed in the position of the driver, and then to design the three-element assembly, i.e. the chair-steering wheel-dashboard assembly. Based on this model, the following step focused on the positioning of the dummy, which has also integrated the defining of the contacts between the components of the dummy and the seat elements. Seeking to model such a behaviour that would highly accurately reflect the driver’s movements in a frontal collision, passive safety systems have also been defined and simulated, namely the seatbelt and the frontal airbag.

Vehicular adhoc network (VANET) adopts or resembles a similar structure of Mobile adhoc network (MANET). The communication in VANET are generally classified into following three categories such as Vehicle to Infrastructure (V2I), Vehicle to Vehicle (V2V) and Hybrid network which is a combination of V2V and V2I network. VANET using the IEEE 802.11p standard has great potential of achieving objectives of Smart intelligent transport system (SITS) for improving transport and road safety efficiency. As more and more services is been provided for V2V based VANET network. It is a challenging task to provide QoS to end user, due to wireless medium that has limited channel availability for transmission. To guarantee QoS and provide efficient network performance, a prioritized MAC need to be designed. Many priority based MAC has been designed in recent times to improve the quality of data delivery to end user. However these do not consider the impact of environment and presence of obstacle which affects the signal attenuation at the receiver end and affecting the QoS of channel availability. To address, this work present an obstacle based radio propagation model, obstacle based CEV (City, Expressway and Village) environmental model and a selective MAC to provide QoS for different services. The proposed model efficiency is evaluated in term of throughput achieved per channel, Collison and success packet transmission. To evaluate the adaptive performance of proposed AMACexperiment are conducted under CEV environment and are compared with existing MAC NCCMA. The outcome achieved shows that the proposed model is efficient in term of reducing Collison, improving packet transmission and throughput performance considering two types of services.

Streszczenie:

An experimental study of the brake-application time of Autonomous Emergency Braking (AEB) system considering the primary accident in an urban area was proposed. Since the functionality of the brake-application time is varied between manufacturers and models, the brake-application time of AEB system must be verified based on driving behaviour in Malaysia. A primary accident was simulated to acquire vehicle deceleration rate in real condition by driving an ego vehicle at a different set of vehicle speeds. The study is focussed on the urban roads in the north region of West Malaysia, i.e. Penang. As a benchmark in this study, the brake-application time (2.6 s) introduced by Mercedes-Benz in the PRE-SAFE® Brakes technology was referred. A new braking permission time was proposed by calculating a minimum deceleration distance and Time-to-Collison (TTC) confirmation time required to brake based on maximum deceleration when a primary accident was simulated. It was found that the brake-application time recommended for the AEB system, specifically AEB City conveys the real driving condition of Penang when a primary accident happens in the urban area. To have a smooth braking and an optimum braking performance during a primary accident, the Forward Collision Warning (FCW) should be activated at TTC ≤ 4.6 s. The partial braking (PB) should be activated automatically when the TTC is approximately 2.9 s. While the automated full braking (FB) phase should begin when the TTC reaches 1.1 s.

Streszczenie:

The predominantly volcanic Piskahegan Group has commonly been considered Early Carboniferous, based on its stratigraphic position. However, spores recently discovered in the Carrow Formation, an alluvial fan deposit in the exocaldera facies, indicate that most, if not all, of the group is of Late Devonian (late Famennian) age. The spore assemblage includes several species reported previously from Ireland, Belgium, and eastern Europe, some of them apparently restricted to the southern parts of the Old Red Sandstone Continent in Late Devonian time. Comparison of records of earliest occurrences suggests that the incoming of some species was diachronous. Volcanic rocks of the Piskahegan Group are coeval with post-Acadian, tin–tungsten-bearing granites elsewhere in New Brunswick and are considered the surface expression of plutonism that resulted from Acadian continental collison.

This article determines the atmospheric situation for the 53 days where any weather station in the Balearic Islands detected torrential rain (equal to or above 200 mm in a single day) during the period 1941–2010. To do this, the synoptic charts for each day were analysed, classifying them in accordance with the types established by Martín Vide (1984) and, in addition, through the automatic synoptic classifications from Jenkinson and Collison (1977). The analysis results demonstrate the importance of cyclonic situations over the Western Mediterranean Basin linked to favourable altitude configurations (earlier presence of cut-off lows—DANA—or troughs). These atmospheric conditions contrast with those that predominate in nearby Mediterranean areas, such as the south-eastern coast of the Iberian Peninsula. Days with torrential rain on the Iberian coastline tend to coincide with easterly advections—a less common occurrence in the Balearics.

This work considers the effects of using the chitosan/sodium dodecyl sulfate (SDS) pretreated filters (CSPFs) as the antiseptic filters on the bioaerosol penetration. Three concentrations of chitosan solutions and chitosan/SDS mixing solutions were used to pretreat the polypropylene fibrous filter to make them antiseptic. The λ virus bioaerosol was generated using a Collison nebulizer, as the challenged bioaerosol. The effects of various factors, including the face velocity and the relative humidity on the bioaerosol collection characteristics were evaluated. Experimental results suggested the pretreatment of chitosan/SDS did have an antiseptic effect on virus bioaerosol and increase the inactivation mechanism. Experimental findings also revealed that the addition pretreatment of SDS did raise the inactivation effect of the chitosan. When adding SDS in the chitosan solution, the ammonium groups could appear and present the antiseptic benefit more obviously. Moreover, the antiseptic of the pretreated filter decreased with face velocity and RH.

This work aims to remove virus bioaerosol by using carbon nanotube corona discharge plasma technology. The λ virus bioaerosols are generated using a Collison nebulizer, as the challenged bioaerosols. Exactly how various factors, including the flow rate (30, 60, and 90 lpm) and the operating voltages (-1.5, -3.0, -4.5, -6.0, and -7.5 kV), affect the bioaerosol reduction characteristics is also evaluated. Experimental results indicate that the corona discharge while using the carbon nanotube electrodes obviously decreases the threshold voltage of plasma. The removal efficiencies of λ virus bioaerosols by using the carbon nanotube corona discharge system at discharge voltages of -1.5, -3.0, -4.5, -6.0, and -7.5 kV are 53%, 60%, 68%, 89%, and 91%, respectively. Additionally, the corona discharge system that incorporates use of the carbon nanotube electrodes performs far superior to that incorporates the use of the stainless steel electrodes in terms of bioaerosol removal efficiency.
