Abstract:
This article describes the dynamics of da‘wah movement of Salafis and their response to its stigmatization as being heretical and radical. The phenomenon of radical movements with their terrorist actions shapes the stigma of being radical to the Salafis. The spread and acceleration of the Salafi movement have put the da‘wah of the traditionalists in trouble. The stigma of Salafis as being radical and heretical results in the resistance against the Salafis to stop their da‘wah in many places. The stigmatization of the Salafis as being radical and intolerant drives the Salafis to show their identity as unidentical with the stigmatization. A number of persecution towards the Salafis is the implication of this stigma. This article is resulted from interviews with Salafi figures and d?‘?s who felt annoyed with the stigmatization. The appearance of Salafis which resembles those stigmatized as radicals lead to the emergence of public opinion that the Salafis are radical, while on the contrary, this article finds that the Salafis in fact fight against radical thoughts that lead to radical and terrorist actions.

Abstract:
ABSTRACTThe purpose of the present study is to evaluate the effect of thermal energy on the yield of and the bactericidal action of hydroxyl radical generated by photolysis of H2O2. Different concentrations of H2O2(250, 500, 750, and 1,000 mM) were irradiated with light-emitting diodes (LEDs) at a wavelength of 400 ± 20 nm at 25°C to generate hydroxyl radical. The 500 mM H2O2was irradiated with the LEDs at different temperatures (25, 35, 45, and 55°C). Electron spin resonance spin trapping analysis showed that the yield of hydroxyl radicals increased with the temperature, as well as the concentration of H2O2.Streptococcus mutansandEnterococcus faecaliswere used in the bactericidal assay. The LED-light irradiation of the bacterial suspensions in 500 mM H2O2at 25°C could hardly kill the bacteria within 3 min, while the bactericidal effect was markedly enhanced with the temperature rise. For instance, a temperature increase to 55°C resulted in >99.999% reduction of viable counts of both bacterial species only within 1 min. The photolysis of 500 mM H2O2at 55°C could reduce the viable counts of bacteria more efficiently than did the photolysis of 1,000 mM H2O2at 25°C, although the yields of hydroxyl radical were almost the same under the both conditions. These findings suggest that the thermal energy accelerates the generation of hydroxyl radical by photolysis of H2O2, which in turn results in a synergistic bactericidal effect of hydroxyl radical and thermal energy.

Abstract:
The kinetics of ring openings of a series of eight (trans-2-arylcyclopropyl)methyl radicals (1) were studied by indirect kinetic methods using Barton's PTOC esters as radical precursors and reaction with PhSeH as the competition reaction. The substituents were CF3, F, Me, and OMe located on both the para and meta positions of the aromatic ring. Syntheses of the radical precursors and the products of the radical reactions are described. Kinetics were determined between -43 and 25°C in four cases (CF3 and OMe substituents) and at 0 and 25°C in the other four cases. The rate constants at 25°C ranged from 1.0 × 1011 s-1 (p-CH3) to 4.1 × 1011 s-1 (p-CF3). The relatively large acceleration of the p-CF3 group, ca. 2.5 times as fast as the parent system with Ar = Ph, correlates well with Adam's ΔD substituent parameters but not with other radical substituent parameters. These calibrated radical rearrangements provide a new set of ultrafast reactions that can be applied in mechanistic probe studies.Key words: cyclopropylcarbinyl radical, kinetics, PTOC esters, benzeneselenol.

Abstract:
Nous étudions dans cette thèse théorique et numérique l'accélération d'électrons lors de l'interaction entre une impulsion laser d'intensité relativiste et un plasma surdense. Cette interaction est très sensible au profil de densité sur la face avant du plasma et deux régimes différents, correspondant à deux thématiques de recherche développées dans cette thèse, peuvent être considérés.Premièrement, pour des interfaces plasma-vide très abruptes, les mécanismes menant à l'émission d'électrons sont bien compris. Les électrons gagnent en particulier une grande quantité d'énergie lors de leur interaction dans le vide avec l'impulsion laser réfléchie. Nous proposons d'optimiser cette accélération en utilisant des faisceaux polarisés radialement, qui sont caractérisés par la présence d'un fort champ longitudinal, capable d'accélérer directement les électrons dans la direction de propagation du laser. Nous montrons que les plasmas surdenses conduisent à une accélération plus efficace que les autres méthodes existantes pour injecter des électrons dans une impulsion polarisée radialement. Ce résultat a été confirmé par des expériences effectuées récemment au CEA Saclay, au cours desquelles la possibilité d'accélérer des électrons dans la direction longitudinale, menant ce faisant à une diminution de la divergence angulaire du faisceau d'électrons, a été démontrée.Deuxièmement, pour des gradients de densité plasma plus grands, l'interaction n'est pas aussi bien comprise. Nous analysons des résultats expérimentaux obtenus récemment au LOA avec des impulsions de quelques cycles optiques et nous montrons que les électrons sont accélérés par une onde de sillage laser formée dans la partie quasi-critique du plasma. Ce processus ne se produit qu'avec des impulsions de quelques cycles optiques, en accord avec la condition de résonance, et se distingue par la rotation des ondes plasmas causée par le gradient de densité
This theoretical and numerical thesis is devoted to electron acceleration from the interaction between a relativistic intensity laser pulse and an overdense plasma. This interaction is very sensitive to the density profile at the plasma front surface and two different regimes, which correspond to two distinct lines of research investigated in this thesis, can be considered.First, for sharp plasma-vacuum interfaces, the mechanisms responsible for electron emission are well understood. The electrons receive in particular a large energy gain from their interaction in vacuum with the reflected laser. We propose to optimize the acceleration by using radially polarized beams, which exhibit a strong longitudinal electric field that can directly accelerate electrons in the laser propagation direction. We show that overdense plasmas lead to more efficient acceleration than other existing methods for injecting electrons into a radially polarized pulse. This result was confirmed by recent experiments performed at CEA Saclay, in which electron acceleration in the longitudinal direction, leading to a decrease in the electron beam angular spread, is demonstrated.Secondly, for larger plasma gradient scale lengths, the interaction is not as well understood. We analyze recent experiments performed in this regime at LOA with few-cycle pulses and find that electrons are accelerated by a laser wakefield formed in the near-critical part of the plasma. This process can only be driven by few-cycle pulses, by virtue of the resonant condition, and is characterized by the rotation of the plasma waves induced by the density gradient

The US ARMY, ARDEC; in cooperation with AMCOM AMRDEC, Missile Guidance and Engineering Directorates; the Office of Naval Research; Naval Surface Fire Support; and the Naval Surface Weapon Center, requires multiphase development of a common, low-cost, high G survivable, high accuracy, Micro Electro-Mechanical Systems (MEMS) Inertial Measurement Unit (IMU) and Common, Deeply Integrated, Guidance and Navigation Unit (DI-GNU) for DoD gun launched guided munition and missile applications. The challenge for the Precision Munition Instrumentation Division (PMID) was to develop a Telemetry System to record the interior and exterior ballistics of a M831 TP-T projectile, which will be used as a carrier for soft recovery testing of IMUs and GNUs. This valuable data that would help The Government and contractors develop and validate multiple MEMS IMU design efforts, culminating with live fire verification performance test of pre-production in the Army’s 155-mm Soft Recovery Vehicle (SRVs) and missiles airframes.

Full text
Abstract:
This thesis is a study into the response and seismic safety of three-dimensional multi-storey concrete structures under concurrent orthogonal seismic excitations. It employs the nonlinear time-history method as its analysis tools. Time-history analyses rely heavily on their utilised earthquake records. Accordingly, this study examines the different approaches of selecting earthquake suites and develops a methodology of selecting representative earthquake scenarios. This methodology is credibly implemented in selecting a far- and a near field suites representative of the New Zealand seismic hazard. The study investigates the response of 6-, 9- and 12-storey concrete structures of different n-X-bays × m-Y-bays. Bidirectional responses of these considered structures are examined and consequently the current combination rules are scrutinised. Consequently this study strongly recommends the use of the 40-percent combination rule in lieu of the widely used 30-percent rule; and the use of time-history analysis in lieu of quasi/equivalent static and response modal analysis methods to avoid their strong dependence on combination rules. An intensive study is conducted employing the incremental dynamic analysis (IDA) technique to investigate structural demands of interstorey drifts, lateral storey drifts and storey accelerations. The study utilises the developed far-field suite and identifies the 50th and 90th percentile demands. Hence it provides easy-to-use expressions to facilitate rapid calculation of the structural demands and the effects of biaxial interactions. An implementation into the Demand and Capacity Factor Design (DCFD) format is presented that infers confidence in the performance levels of the considered structures. The study also draws attention to the importance of considering storey accelerations as their storey values reach as high as 10 × PGA. A sensitivity study is conducted by repeating the IDA investigation while using the developed near-field suite. Subsequently a comparison between the near- and the far-field results is conducted. The results were markedly similar albeit of less magnitudes until the (seismic hazard) intensity measure IM = Sa(T₁) = 0.4g when the near-field results show sudden flat large increase in demands suggesting a brittle collapse. This is attributed to the higher content of the higher mode frequencies contained in near-field ground motions. Finally, the study examines the (vectorial) radial horizontal shear demands in columns and beam-column joints of the previous far- and near-field studies. The combined radial shear demands in corner, edge and internal columns and joints are evaluated that roughly show a square-root proportional relationship with IM that exhibit somewhat brittle failure at IM ≥ 0.35g. Shears demands in the (4-way) internal columns and the (2-way) corner joints show highest magnitude in their respective class. The results suggest transverse joint shear reinforcement of 1.5, 1.0 and 0.5 of the longitudinal reinforcement of the neighbouring beam respectively for corner, edge and internal joints. An implementation of a proposed practical (and simpler) DCFD format shows satisfactory confidence in columns performance in shear up to IM = 0.35g, conversely to joints unsatisfactory performance in shear at the onset of inelastic behaviour (IM > 0.05g).

TE-averaged technique is an application to measure Glutamate (Glu), one primary excitatory neurotransmitter of the central nervous system on the 1H MR spectrum at 2.35 ppm. For obtaining TE-averaged MRSI data sets with multiple TEs was time consuming. Previous study had shown that radial proton echo planar spectroscopic imaging (rPEPSI) and data-sharing radial PEPSI (dsrPEPSI) were feasible to measure Glu, and it can accelerate to 16-fold by dsrPEPSI. However, the increased speed will decrease both SNR and spectral quality. From the result of investigation, 4-fold is a reasonable length for clinical use and keeps the spectral quality well.

Abstract:
This chapter explains how anticipations of war in 1861 raised passions among people who sensed a rare chance to make history if they had the courage and foresight to seize the historical moment. Sounds of looming war—shrill voices, loud drumming, and marching tunes—stirred feelings of forward movement, bloodshed, and an acceleration of history. A host of people felt this way, from career military officers and radical reformers to Republican office holders and southern nationalists. When thousands of volunteers and runaways anticipated these opportunities by racing to the battlefront, they shaped the scale, duration, meaning, and conduct of the war.

Full text
Abstract:
The urban condition is today being radically transformed. Urban restructuring is accelerating, new urban spaces are being consolidated, and new forms of urbanization are crystallizing. How can these transformations be deciphered? In this book, critical urban theorist Neil Brenner argues that confronting this challenge requires not only intensive research on urban restructuring but new theories of urbanization. To this end, Brenner proposes an approach that breaks with inherited conceptions of the urban as a bounded settlement unit—the city or the metropolis—and explores the multiscalar constitution, political mediation, and ongoing rescaling of the capitalist urban fabric, from the local and the regional to the national and the planetary. New Urban Spaces offers a paradigmatic account of how rescaling processes are transforming inherited formations of urban life, the role of multiscalar state spatial strategies in animating them, and their variegated consequences for emergent patterns and pathways of urbanization. The book also advances an understanding of critical urban theory as radically revisable: key urban concepts, methods, and cartographies must be continually reinvented in relation to the relentlessly mutating worlds of urbanization they aspire to illuminate.

Abstract:
Set against the backdrop of the COVID-19 crisis, Future War and the Defence of Europe considers in the round how peace can be maintained on a continent that has suffered two cataclysmic conflicts since 1914. COVID-19 and the trend-accelerating impact of such pandemics is first considered. The book then weaves history, strategy, policy, and technology into a compelling analytical narrative that sets the scale of the challenge Europeans and their allies will face if Europe’s peace is to be upheld in a transformative century. The book challenges foundational assumptions about how Europe’s defence is organized, the role of a fast-changing transatlantic relationship, NATO, the European Union, and their constituent nation-states. At the heart of the book is a radical vision of a technology-enabling future European defence built around a new kind of Atlantic alliance, an innovative strategic public–private partnership, and the future hyper-electronic European force it must spawn. Europeans should be under no illusion: unless they do far more for their own defence, and very differently, all that Europeans now take for granted could be lost in the maze of hybrid war, cyber war, and hyperwar they must face.

Abstract:
Book Abstract: Despite countless reports and Government policy announcements on the housing crisis over decades, the scale and depth of the crisis continues. Homelessness, shortages of social housing, rents and house prices continue rise year on year. The word affordability has become meaningless. Land landowners and housebuilders and property investors have made huge profits out of this crisis. This book focusing in examples from London and Northamptonshire examines the power of the ‘finance-housebuilding ’ complex arguing that this property lobby is the main blockage for change and reform. It explains why the housing and planning system has become increasingly dysfunctional over the last 40 years accelerating with the impact of the 2008 Crash. The book gives examples of how the property lobby has been highly effective in manipulating Government housing and planning policy for its own benefit, to the detriment of those in housing need. It shows how the housebuilders business model, backed by Government grants and subsidies, has played a central role in perpetuating the crisis. The property lobby has succeeded in diverting attention from themselves onto the town planning system which has been scapegoated for holding back new house building. The result is that the housing crisis and the power behind it is hard baked into the UK economy. It must be addressed by radical reform of the property, planning and finance system. Without these reforms homelessness, poor housing, and lack of affordability will continue indefinitely.

ZusammenfassungWir entwickeln in diesem Kapitel einen Index zur Erfassung der digitalen Reife („Digital Maturity Index“, DMI) und haben damit bei 160 deutschen und 785 Unternehmen weltweit die bisherige digitale Transformation untersucht.Die Ergebnisse für Deutschland stützen die Hypothesen, dass die Gewinnwirkung umso höher ist, je stärker durch die Digitalisierung Technologien und Prozesse (Activities) und mehr noch Angebote und Geschäftsmodelle (Businesses) verändert werden, die Gewinnwirkung der Digitalisierung umso höher ist, je stärker Veränderungsfähigkeiten (Dynamic Capabilities) aktiviert und dadurch operative Fähigkeiten (Operational Capabilities) neu konfiguriert werden und belegen damit, dass die Gewinnwirkung der Digitalisierung mit der digitalen Reife steigt. Die Ergebnisse lassen sich entlang der vier Teilindizes (Business Index, Activity Index, Dynamic Capability Index und Operative Capability Index) genauer betrachten. identifizieren sechs Archetypen digitaler Unternehmen (Champions, Potenzialträger, Innovatoren, Optimierer, Folger und Nachzügler) und zeigen, dass nur fünf Prozent der deutschen Unternehmen zu den digitalen Champions zählen, die im Zuge der Digitalisierung sowohl ihre Leistungen als auch ihre Fähigkeiten radikal verändert haben. Die sechs Typen digitaler Unternehmen unterscheiden sich darin, wie stark sie ihre Leistungen und Kompetenzen, aber auch ihre Wertschöpfung und die IT digitalisieren und wie schnell sie die digitale Transformation managen. Die Ergebnisse der Unternehmen weltweit ermöglichen einen Branchenvergleich, gemäß dem Anbieter von Industrieprodukten und Dienstleistungsanbieter bereits eine deutlich höhere digitale Reife aufweisen als z. B. Automobilunternehmen. ermöglichen einen Vergleich der bisherigen digitalen Transformation von Unternehmen in der EU, in Amerika und Asien, der relativ große Ähnlichkeiten zwischen den Regionen zeigt.

ZusammenfassungWir wollen in diesem Kapitel zeigen, wie Unternehmen die Chancen der Digitalisierung nutzen können: durch Verbesserung oder Veränderung zunächst der unternehmerischen Prozesse (z. B. durch die digitale Fabrik bzw. Industrie 4.0) und der dahinter liegenden digitalen Technologien (z. B. ein mehrschichtiges Fertigungsmanagement, MES), als den „Digital Activities“. dann der Angebote, d. h. Produkte und Dienstleistungen (z. B. ein Angebot von Digitalkameras), die Unternehmen in Geschäftsmodelle – einzeln umsetzen oder verbindlich ausgerichtet auf einen definierten Kreis von Partnern (in einem Ecosystem) - umsetzen, als den „Digital Businesses“. durch radikale Veränderungen der Leistungen, die sehr viel weitreichender sind, als eine Verbesserung oder eine inkrementelle Veränderung der Technologien, Prozesse, Angebote und Geschäftsmodelle. Denn sie bedeuten die Entwicklung völlig neuer Geschäftsmodelle bzw. Geschäftsmodellinnovationen, die sich als neue Wege des Denkens auf völlig neue Angebote am Markt beziehen und auf neuartige Technologien und Prozesse stützen. Damit ermöglicht die Digitalisierung eine Neuausrichtung der unternehmerischen Leistungen (Digital Performance) und treibt die Transformation von Unternehmen.Dabei gilt, dass die Gewinnwirkung umso höher ist, je stärker Unternehmen dadurch Technologien, noch stärker Prozesse, mehr noch Angebote und am meisten Geschäftsmodelle verändert werden.

Abstract:
More people than ever before are moving more frequently and at accelerating speeds, often for shorter periods of time. These mobilities are largely dependent on unsustainable high-carbon technologies. The continued and accelerating growth of transportation emissions is attributed to changing mobility patterns among the high emitters of hypermobile developed societies, combined with the rapid development of high carbon intensity transport systems in emerging economies. Mitigation of transport emissions remains largely absent from the political agenda, despite growing recognition of the urgent need to address transportation emissions, because it is fundamentally incompatible with neoliberal ideals. The level of decarbonisation required to align regional and global transportation systems with the agreed targets of the Paris Climate Agreement (2015) has proved to be a particularly acute challenge. The Agreement recognises that radical and system-wide transitions toward low carbon mobility are urgently required. It is critically important that the varied social, cultural and geographic contexts of low carbon mobility transitions that are identified in Low Carbon Mobility Transitions are taken up and acted upon to inform the low carbon mobility transformations that are so obviously and urgently required. These insights must inform efforts to ensure the full accountability of transportation emissions, and to ensure that the INDCs that are outlined in the Paris Climate Agreement (2015) are upheld and achieved in full measure.

Abstract:
The globalization of the 21st century has changed economic and other realities far beyond the expectations of most individuals. The competitive landscape continues to be reinvented due to such factors as accelerating globalization, changing demographics, rapid technological advances, shorter business/product life cycles, innovation, and productivity. This chapter focuses on why there is a need for perpetual Government-University-Industry (GUI) collaboration, especially in advanced economies, and some options on how to achieve it effectively. The chapter commences with an introduction to the realities of contemporary globalism that have raised the need for this collaboration, and the body then outlines the status of GUI collaboration in the world’s four largest economies: China, India, Japan, and the USA. There is a model example of ideal GUI collaboration in the discussion section for reference. The conclusion synthesizes the earlier discussions and provides suggestions for consideration regarding optimum GUI collaboration, most notably a list of seven “Best Practices” provided by Massachusetts Institute of Technology in the USA.

Abstract:
The Ultra Compact Combustor (UCC) has shown viable merit for significantly improving gas turbine combustor performance. This concept combines a trapped-vortex approach with a circumferential cavity utilizing buoyancy and high g-loading to improve efficiency and reduce combustor size. Models for small engines can provide g-loading up to 4,000 g’s. However, as the scale of the combustor increases, the g-loading will necessarily decrease. Thus, the importance of understanding the effect of g-loading is pivotal to the applicability of this design to larger engine diameters. The Air Force Institute of Technology’s Combustion Optimization and Analysis Laser (COAL) laboratory studied this effect with sectional models of the UCC. By using both straight and curved sections of the radial cavity, the g-loading can be varied from 0–15,000 g’s. Particle Image Velocimetry (PIV) was used for velocity fields and turbulence statistics. Two-line Planar Laser-Induced Fluorescence (PLIF) of the hydroxyl (OH) radical was used for 2-D temperature profiles. Single-line PLIF was also used for flame location where OH concentrations were too low for temperature determination. Several cases were studied with varying both the equivalence ratio and the main/cavity mass flow ratio. Through the synthesis of velocity fields, temperature and flame location PLIF data, the effect of g-loading was accurately characterized. The immense radial acceleration acts to significantly increase the turbulent intensity present in the combusting regions. This increased turbulent intensity resulted in increased mixing and subsequently a significantly increased flame speed causing a reduced chemistry time. Because the chemistry time was reduced, there was less OH present in the main flow for the high g-load cases due to the combustion process being significantly further progressed when the cavity flow mixes with the main flow.

Abstract:
Abstract At the Holloman High-Speed Test Track (HHSTT), momentum exchange with water is used to decelerate sleds from very high speeds (> Mach 1). This process, at the HHSTT, is called ‘water braking’. Improving the prediction capabilities of water braking phenomena has the potential to result in radical changes in the designs of sleds, improve rocket sled velocity-time test profile predictions, provide greater confidence of braking mechanisms, and decrease risk in the recovery of critical infrastructures. Understanding the water?s behavior with the sled is critical to predicting how the water could damage the sled, which affects the recoverability of the sled and can determine the success of a mission. Traditionally, sled design for the test missions for water braking has been guided by empirical/hand calculations to estimate the forces on various components. The calculations involved various approximations in arriving at the force balance law and predicting the acceleration/deceleration profile. In partnership with the HHSTT, we performed preliminary simulations to develop a predictive model for the HHSTT sled tests at various velocity regimes. The (preliminary) CFD results from different geometry configurations for the sled and modeling parameters will be presented.

Full text
Abstract:
The flow and mixing in rotating zigzag microchannel is investigated experimentally and numerically with objective of improving mixing, which is largely due to secondary or cross-flow in the cross-sectional plane of the channel and the bend connecting non-radial angled channel segments. Unlike the conventional stationary zigzag channel, crossflow in the zigzag channel is highly intensified from a combination of (a) centrifugal acceleration component in the cross-sectional plane due to the angled channel segments, (b) centrifugal acceleration generating Görtler vortices at “channel bends”, and (c) Coriolis acceleration. When the channel segment in the zigzag channel is inclined towards rotation direction (prograde), all three accelerations are aligned intensifying the crossflow; however, when it is inclined opposite to rotation (retrograde), Coriolis acceleration negates the other two accelerations reducing mixing. A numerical model has been developed accurately accounting for the interactions of throughflow, crossflow and material dispersion by diffusion and convection in a rotational platform. An experimental microfluidic platform with rotating zigzag microchannel has also been developed. Experimental results on mixing quality carried out at two rotation speeds compared well with prediction from the numerical model. The overall mixing quality of a rotating zigzag channel is much improved compared with that of a stationary zigzag channel.

In ASME Turbo Expo 2014: Turbine Technical Conference and Exposition. American Society of Mechanical Engineers, 2014. http://dx.doi.org/10.1115/gt2014-26879.

Full text
Abstract:
The wide-chord swept fan blade (WCSFB) has been extensively used in a advanced high bypass ratio turbofan engines. This paper explores the nature of WCSFB tip clearance. From the static analysis, it is found that the tip radial clearance at leading and trailing edge of WCSFB will be reduced with either bending or torsional deformation of the blade. And the change of the tip radial clearances varies with the twist angle. In this study, dynamic response of the WCSFB with different angular accelerations of the engine has been analyzed. It shows that when the angular acceleration of the fan rotor reaches a certain level, considerable bending and torsional deformation of the blade will occur, accompanied by the reduction of the tip radial clearance, which may lead to abnormal rubbing/impact between the blade tip and the casing. This may cause severe consequence for the blade and casing of the engine. The numerical simulation results show that the rubbing/impact between the WCSFB tip and the casing under angular acceleration loads can lead to local buckling of the tip leading edge of the blade, which will cause severe damage at the blade tip. Moreover, the influence of vibration and mass imbalance of the rotor on the fan blade tip clearance is also analyzed. In this paper, the results of a rig test under irregular acceleration for the WCSFB rotor is also presented, which validates the analytical results. The numerical simulation and test results will assist the blade tip clearance design to reflect the nature of the WCSFB under irregular acceleration to ensure safety.

Abstract:
Abstract Although numerous studies have investigated how shocks and vibrations contribute to bottomhole assembly (BHA) failures during hole-making, very few have explicitly focused on shock and vibrational behaviors during drillpipe connections. This study adopts a data-driven approach to explore various connection practices and their associated shocks and vibrations, aiming to propose optimum "connection recipes" that minimize negative drillstring impacts during connections. This study utilized data from surface sensors as well as downhole accelerometers and gyroscopes installed both at a downhole sub and the bit. In total, 520 connections from 5 lateral sections were studied. Several quality checks and corrections were performed to ensure synchronization between surface and downhole data. The analyses focused on two connection phases specifically: going off-bottom and going back to bottom. The presence of stick-slip events and high magnitudes of both maximum and root mean squared (RMS) radial accelerations were examined together with the associated surface drilling parameters. Various visualization approaches were performed to help demonstrate the vibration and shock behaviors resulting from different going off-bottom and going back to bottom practices. The analyses showed that restarting surface rotational speed at low values (≤ 40 RPM) risks inducing stick-slip events when going back to bottom. When the surface RPM was increased sufficiently, a notable reduction in RMS radial acceleration was observed. Maximum radial acceleration magnitude was highest before WOB application, which could be mitigated by immediate WOB re-application. Appreciable variation in the maximum radial acceleration was apparent when restarting at low (≤ 15 klbf) WOB values. When going off-bottom, drilling off should be accompanied by a reduction in the surface rotational speed to avoid a jump in the maximum radial acceleration values. This work provides suggestions on how to execute better connections. Since the impacts of shocks and vibrations during connections have previously been largely overlooked, this study fills a knowledge gap to help establish better practices and automation routines to improve the lifespan of the bit and downhole tools.
