Abstract:
There various factors gives influence in determining the fuselage shapes, such as the payload, cockpit, wing and tail placements or in manner up and down loading the payload for a cargo aircraft. These factors may come up the fuselage is no longer as symmetrical fuselage but represent as a cambered fuselage. As results the lift coefficient as well as its pitching moment coefficient is no longer equal to zero as the angle of attack goes to zero. Basically the manner how to determine the fuselage aerodynamics characteristics for cambered fuselage can be done in similar way as in the case of symmetrical fuselage by simply replacing the angle of attack α term with (α-αL=0), where αL=0 represent the angle of attack at zero lift. The present work use a similar manner in determining the zero lift angle of attack as it had been used in DATCOM software. To investigate the effect of camber on the aerodynamics characteristic fuselage, the present work use a fuselage model with a circular cross section where the location of center of the circle placed along the fuselage’s camber line. The fuselage’s camber line defined according to the definition of camber line of NACA airfoils. Aerodynamics analysis on over various fuselage models indicate that the maximum camber line thickness and their position give a significant influent to the fuselage aerodynamics characteristics.

Abstract:
A variable-camber aerofoil with integral pressure tappings has been built to investigate the nature of the flows around two-dimensional, highly cambered, sail-like aerofoil sections with circular masts. Data have been obtained in the form of static pressure distributions over representative ranges of Reynolds number, camber ratio, incidence angle, mast diameter/chord ratio and mast angle. Two sail shapes—based on the NACA a = 0.8 and NACA 63 mean-line camber distributions—were involved in the test program. All flow regimes present have been identified and related to the salient model and flow parameters.

Abstract:
The article discusses the impact of design solutions of vehicle suspensions into angles of body roll. It was shown which type of suspensions is better from this point of view. There were examined the dependence of the suspensions parameters on the vehicle body roll angle. The influence of camber angle on the force transmitted to the tire contact with the road surface was analysed. The lateral forces were measured on the test stand. There was tested dependency of lateral forces from the sideslip angle for different angles of camber. Was analysed change of lateral forces generated by camber angle on the vehicle which was made on a scale ~ 1:5 during tests carried out on the testing track. For this purpose, two tests have been selected: first one allowing the measurement in steady motion conditions, the second one with dynamic change of direction of vehicle motion. The graphs show the effect of camber angles on the controllability and stability of the vehicle motion.

Abstract:
Purpose This paper aims to investigate the impact of aerofoil camber on the performance of micro-air-vehicle-scale cycloidal propellers. Design/methodology/approach First, experiments were conducted to validate the numerical methodology. After that, three turbulent models were compared to select the most accurate one. Then, 2D numerical simulation was carried out on 11 aerofoils with different cambers, including five cambered aerofoils, one symmetrical aerofoil and five inverse cambered aerofoils. The inverse cambered aerofoils are symmetrical about the chord line to the corresponding cambered ones. Findings The cycloidal propeller with large cambered aerofoil gives the lowest hovering efficiency, but with symmetrical aerofoil or small inverse cambered aerofoil shows the highest. Also, blades with large cambered aerofoil display high performance at the upper part of its trajectory, while with symmetrical aerofoil or the inverse cambered aerofoil have their best at the lower part. In addition, intensified downwash can be observed in the rotor cage for all cases. When a blade runs through the top-left part of its circle path, all cases display the feature of deep dynamic stall. When the blade travels through the nadir of its path, the actual angle of attack is close to zero due to the strong downwash. Furthermore, there exits intensified blade-vortex interaction induced by the preceding blade for large cambered aerofoils at the lower-right part of its trajectory. Practical implications This paper develops a new cycloidal propeller which is more efficient than the one already present. Originality/value This paper discovers that the aerofoil camber is a vital design parameter in the performance of cycloidal propeller, and the authors expect that the rotor with deformable aerofoil on camber would achieve much higher efficiency.

Abstract:
A suspension system with the capability of cambering has an additional degree of freedom for changing camber angle to increase the maximum lateral tire force. This study investigates the effects of cambering on overall vehicle stability with emphasis on applications to urban vehicles. A full vehicle model with a reliable tire model including camber effects is employed to investigate the vehicle dynamics behavior under cambering. Besides, a linearized vehicle model is used to analytically study the effects of camber lateral forces on vehicle dynamics. Vehicle behavior for different configurations of camber angles in front and rear wheels is studied and compared. Then, an active camber system is suggested for improvement of vehicle lateral stability. Specifically, performances of active front camber, active rear camber, and their combination are investigated. The results show that a proper strategy for camber control can improve both yaw rate and sideslip angle, simultaneously. Finally, the active front camber system is compared with the well-known active front steering. It is shown that, utilizing more friction forces at the limits, active front camber is more effective in improving maneuverability and lateral stability than active front steering.

Abstract:
This study discusses the effect of variable alignment control suspension on vehicle dynamics by altering the suspension arm's length. In this system, two of the four arms of the front multi-link suspension can extend or contract depending on each driving condition to control the camber and caster angles independently. a camber angle and a caster angle are altered by the action of upper and lower control actuators. The camber angle control contributes to the increase in a turning limit with the improvement of tire footprints condition, and the caster angle and caster trail control aid the wheel's ability to right itself with a suitable steering feeling for the driver. Vehicle tests are conducted using a prototype vehicle equipped with a variable alignment control system to clarify the above effects, and remarkable improvements in a vehicle dynamics are verified.

Abstract:
Abstract Theoretical and experimental study is conducted on the contact pressure distribution of a radial tire in motion under various camber angles. Tire construction is modeled by a spring bedded elastic ring, consisted of sidewall springs and a composite belt ring. The contact area is assumed to be a trapezoidal shape, varying with camber angles and weighted load. The basic equation in a quasi-static form is derived for the deformation of a running belt with a constant velocity by the aid of Lagrange-Euler transformation. Galerkin's method and stepwise calculation are applied for solving the basic equation and the mechanical boundary condition along both sides of the contact belt part subjected to shearing forces transmitted from the sidewall spring. Experimental results on the contact pressure, measured by pressure sensors embedded in the surface of the drum tester, correspond well with the calculated ones for the test tire under various camber angles, running velocities, and weighted loads. These results indicate that a buckling phenomenon of the contact belt in the widthwise direction occurs due to the effect of camber angle.

Abstract:
This study examined the effects of 0, 4, and 8 degrees camber on the physiological and perceptual responses in younger (19-44 years) and older (45-74 years) sedentary, able-bodied men propelling a wheelchair at 2 kmh. Physiological and perceptual (rating of perceived exertion, RPE) responses were monitored using standardized procedures. Significant increases (p < .05) in oxygen uptake, ventilation rate, and heart rate were observed with increasing camber angle. These values were not significantly (p > .05) different between age groups. Central and peripheral RPE was unchanged as a result of camber angle in either group. Central RPE was significantly higher (p < .05) for the older participants at a camber angle of 8 degrees. It was concluded that the physiological stress increases with camber angle during manual wheelchair propulsion at 2 kmh in younger and older men. The higher perceptual stress in older participants could be due to performance at a higher percentage of their maximum physiological capacity.

Abstract:
This paper presents the design and wind tunnel testing of a morphing camber system and an estimation of performances on an unmanned aerial vehicle. The morphing camber system is a combination of two subsystems: the morphing trailing edge and the morphing leading edge. Results of the present study show that the aerodynamics effects of the two subsystems are combined, without interfering with each other on the wing. The morphing camber system acts only on the lift coefficient at a 0° angle of attack when morphing the trailing edge, and only on the stall angle when morphing the leading edge. The behavior of the aerodynamics performances from the MTE and the MLE should allow individual control of the morphing camber trailing and leading edges. The estimation of the performances of the morphing camber on an unmanned aerial vehicle indicates that the morphing of the camber allows a drag reduction. This result is due to the smaller angle of attack needed for an unmanned aerial vehicle equipped with the morphing camber system than an unmanned aerial vehicle equipped with classical aileron. In the case study, the morphing camber system was found to allow a reduction of the drag when the lift coefficient was higher than 0.48.

Abstract:
This Bachelor thesis project is an experimental investigation of the effect of camber and toe angles on rolling resistance. The experiments are done on Sleipner, a Prototype car made by KTH students, which takes part in the Shell Eco Marathon competition in Rotterdam. In order to succeed in the competition it is crucial to reduce energy losses in order to get an as energy efficient vehicle as possible. The experiment involves tests where Sleipner is manually dragged across a flat floor and its position and the dragging force are logged with a pulse encoder and a load cell respectively. This is done ten times for each chosen wheel alignment (specific camber and toe angle), in order to be able to find the optimal setting with respect to minimization of rolling losses. The tests are performed in the Integrated Transport Research Lab at KTH. The obtained data is then used to calculate the magnitude of the rolling friction.It is found that the more negative the camber angle, the larger the rolling resistance. The smallest camber angle investigated is -3º which gives a coefficient of rolling friction (Cr) of 0.0052. The second camber angle is -5º giving a Cr value of 0.016 and the largest camber angle is -7º giving a Cr value 0.019. It was also found that, with the minimum camber angle, toe out gives a larger coefficient of rolling resistance than toe in; 0.0081 compared to 0.0052.The report also delves into additional effects of camber and toe angles on the vehicle’s behaviour while driving and it is found that negative camber angle gives better stability in the car when cornering and that toe in gives better stability in straight line driving.With these results it is concluded that Sleipner should have a slight camber angle of -3º and toe in of 0.5º so as to have the best results in the Shell Eco Marathon.
Detta kandidatexamensarbete i maskinkonstruktion är en experimentell undersökning av hur camber och toe- vinkeln påverkar rullmotstånd. Testerna är gjorda på Sleipner, ett fordon utvecklats av studenter på KTH, som tävlar i Prototyp-klassen i Shell Eco Marathon som hålls i Rotterdam i maj. För att få ett så energisnålt fordon som möjligt är det naturligtvis av största vikt att minska alla olika typer av förluster så mycket som möjligt. En stor del av dessa förluster är förluster som sker för att överkomma rullmotstånd, som i sin tur är beroende av många olika faktorer. Målet med undersökningen var att kunna ge en rekommendation på den optimala vinkelinställningen på Sleipner inför årets tävling.Testerna som bedömdes ge det bästa resultatet var dragtest, då Sleipner drogs med handkraft över ett platt golv. Dragkraften registrerades med en kraftgivare fastsatt centrerat på ramen och en pulsgivare på bakaxel registrerade positionen. Den data som registrerades användes för att kunna räkna ut storleken på rullmotståndet. För varje vald inställd vinkel, både camber och toe, så drogs Sleipner tio gånger över golvet, fem gånger i varje riktning. Detta för att kunna räkna ut medelvärden och på så sätt minska osäkerheten i resultaten. Alla tester utfördes i Integrated Transport Lab på KTH.Resultaten visade att ju större negativ camber vinkel, desto större blev rullmotståndet. Den minsta camber vinkeln som undersöktes var -3º, vilket gav en rullmotståndskoefficient (Cr) på 0.0052. Nästa camber vinkel som prövades var -5º, vilket gav Cr till 0.016 och den sista vilken var -7º och det resulterade i Cr-värde på 0.019. När den bästa camber vinkeln funnits, så utfördes tester med toe out, vilket visade att toe out gav ett större värde på rullmotståndet än toe in, Cr på 0.0081 jämfört med 0.0052.Rapporten behandlar vidare andra effekter av camber och toe-vinklar, såsom inverkan på fordonet under körning. Det visar sig att negativ camber vinkel ger bättre stabilitet, speciellt vid kurvtagning, och toe in ger bättre stabilitet vid körning rakt fram. Med de resultat som erhölls resulterade i en rekommendation på att Sleipner skulle ha camber vinkel på -3º, och toe in på runt 0.5º för att kunna uppnå bästa resultat i tävlingen.

Abstract:
Modern day cars are often equipped with a vision system that collects informa- tion about the car and its surroundings. Camera calibration is extremely impor- tant in order to maintain high accuracy in an automotive safety applications. The cameras are calibrated offline in the factory, however the mounting of the camera may change slowly over time. If the angles of the actual mounting of the cam- era are known compensation for the angles can be done in software. Therefore, online calibration is desirable. This master’s thesis describes how to dynamically calibrate the roll angle. Two different methods have been implemented and compared.The first detects verti- cal edges in the image, such as houses and lamp posts. The second one method detects license plates on other cars in front of the camera in order to calculate the roll angle. The two methods are evaluated and the results are discussed. The results of the methods are very varied, and the method that turned out to give the best results was the one that detects vertical edges.

This chapter begins with the story of Yung Kuai, a Chinese Educational Mission (CEM) student who graduated from Yale but remained in America for the rest of his life where he married a Euro-American woman and raised a biracial family, which he supported by working as a diplomat at the Chinese embassy. Yung Kuai's story reveals the holes in Asian exclusion, from the welcomed presence of the CEM in New England even at the height of the anti-Chinese movement in California, and highlights the efforts of Americans such as missionaries, educators, and diplomats who treated Chinese as culturally distinct yet malleable in ways that could be turned to advantage. Fears that unilaterally imposed immigration restrictions might damage relations with China meant that initial forays into imposing controls came through diplomatic negotiations.

Abstract:
This chapter shows that the Grotton–St. Ange family was the most important political and military family in Upper Louisiana for the half century between 1720 and 1770. Louis St. Ange de Bellerive first came to prominence under the sponsorship of his father, Robert Grotton St. Ange. Shortly after Robert Grotton St. Ange's marriage to his second wife, Élisabeth Chorel, in 1718, the couple and Robert's two sons by his first wife, Pierre and Louis, headed west to establish the St. Anges as a leading family in the Illinois Country. This chapter traces the history of the Grotton–St. Ange family in the Illinois Country and looks at the expeditions of Étienne Veniard de Bourgmont, the first white man to ascend the Missouri River valley in 1714 and the one who built Fort d'Orléans. It also considers the presence of the St. Ange family at Fort d'Orléans, where Louis St. Ange de Bellerive replaced Robert Grotton St. Ange as commandant.

Abstract:
This chapter argues that English culture around the year 1000 had reached an ideological crisis, in the aftermath of the Benedictine Reform movement, which had placed monasticism at the forefront of society. The king was envisaged as the head and protector of the monastic church, while influential writings regarded society as on the edge of an apocalyptic decline, and castigated laypeople for their impious lives. The old heroic ideals of Anglo-Saxon society came under unprecedented ideological strain, and the historical writings of the Anglo-Saxon Chronicles show a bleak and pessimistic outlook. Only when new secular ideals had gained ground in English political culture could this pressure be relieved.

This chapter outlines some the Irish evidence for later medieval settlement and society and the seismic shift in settlement which came about as a result of invasion and then conquest of the island by the Anglo-Normans, beginning in ad 1169. There was always a particular defensive aspect to this settlement, both in a rural and in an urban context, but the economy of the Anglo-Norman generally flourished until crisis in the second half of the fourteenth century. This discussion covers castles, tower houses, moated sites, rural settlement, towns, and churches before describing trade and contact with Britain. Pottery imports are highlighted, concluding that Ireland is to be seen as anything but peripheral to the broader context of medieval Europe.

Abstract:
Lateral force of a tire depends on the sideslip and camber angles. Camber angle is the roll angle of a tire with respect to the road surface and may be a function of the vehicle roll angle. However, the camber angle may also be generated by a steer angle because of suspension and steering mechanisms. A steerable tire turns about a steering axis which can be determined by the caster and lean angles. The steered tire will gain a camber angle because of caster and lean angles. This camber-steering might be in favor or opposite to the direction the vehicle is supposed to turn. A few negative degrees caster angle is required for directional stability. Although the lean angle can be set to be zero, it is usually set to a few degrees positive value to help steering. Therefore, the camber angle of a steerable tire is a function of steering, caster, and lean angles in a nonlinear manner. In this investigation, we employ the screw theory to model the rotation of a tire about the steering axis kinematically. A set of equations will be found to determine the camber angle as a function of caster, lean, and steer angles. Determination of the associated camber trust due to steering would be the application of this study.

Abstract:
The lateral force created by a tire necessary for a vehicle to change direction is generated by slip and camber angles. Camber angle may be defined as the angle between a vertical line passing through a wheels’ center and the horizontal projection of this line onto the wheel. If the axis which the tire turns about is not parallel to the vertical axis, a change in camber will be induced as a result of the change in steer angle. This axis is called the steering axis and can be determined by the caster and lean angles relative to the wheel position in a body coordinate frame. The relation between the steer and camber angles may favor or detract from the lateral force being generated by the tire. This paper describes a method for determining the induced camber angle with respect to steer angle. In this method the wheel is defined throughout the steering range as a circle. The lowest point of the circle with respect to the global coordinate frame may then be defined via a method for determining maxima and minima. This point is then used to determine camber angle with respect to steer angle throughout the steering range. The lowest point of the tire may also be used in finding ride height and body roll due to change in steer angle. A sensitivity analysis reflects the suspension behavior for a variety of different suspension parameters. The relative difference between the induced steer angle about the steering axis and the actual steer angle with respect to the body coordinate frame are relevant in developing more accurate vehicle dynamics models.

Abstract:
The accuracy of multi dimensional simulation of vehicle dynamics has been significantly increased for both passive and active vehicles which are equipped with advanced electronic components. Recently, one of the subjects that has been considered is increasing the car safety in design. Therefore, many efforts have been done to increase vehicle stability especially during the turn. It is also very important in three wheel car. One of the most important efforts is adjusting the camber angle in the car suspension system. Camber angle as well as the vehicle stability has major effects on the wheel slip, reducing rubber abrasion, acceleration and braking. Since the increase or decrease in the camber angle impacts on the stability of three wheel vehicles, in this paper, a car suspension system mechanism is introduced by which camber angle could be adjusted furthermore the mechanism is user friendly applicable and also economic. Actually, a passive double wishbone suspension system with variable camber angle has been designed, analyzed and subsequently manufactured. This mechanism was modeled in Visual Nastran software and kinematic analysis was presented. It can change camber angle from −5.5 to 5 degrees. In this work, two different modeling is presented, active geometry system (variable camber) and passive (conventional suspension system) then the rate of Roll and Yaw angle were discussed to investigate and compare models stability in same condition. Simulation and test results have shown that vehicle stability in active geometry model is sustained more than conventional models.

Full text
Abstract:
This paper presents the relation between circumferential fluctuation and the geometric and flow parameters. The governing equations are derived by circumferentially averaging the three-dimensional (3D) Navier-Stokes equations. Different types of compressor cascades are simulated and the circumferential fluctuation terms are extracted according to the definition of circumferential average. Three different blade profiles are chosen, including CDA, C4 and NACA65 profile, respectively. The peak value of circumferential fluctuation terms often occurs at the leading or the trailing edge and increases as the radius grows. Meanwhile, the circumferential fluctuation terms exist at the inlet of the blade which can be accurately calculated. 0°, 15° and 30° camber angles are chosen to study the influence of camber angle. When the camber angle is smaller, the flow is more uniform and therefore, the value of circumferential fluctuation is lower. Different incidence angles are compared to discuss the relationship between circumferential fluctuation and incidence angle. For specific term of circumferential fluctuations, the distribution curves are different.

Abstract:
Asymmetric dampers invariably employed in automotive suspensions are known to cause ‘damper jacking’. The influence of the damper jacking on the suspension kinematic responses, particularly variations in the camber angle, are generally ignored while synthesizing a damper. This study presents influences of damper asymmetry on the camber angle variations of a double wishbone type of suspension together with the dynamic responses under measured urban road inputs. Simulation studies employing a kineto-dynamic quarter-car model comprising a bilinear damper revealed increase in the camber angle variations with an increase in the damper asymmetry, while this increment showed nonlinear relation with the suspension deflection. This study further investigates synthesis of an optimal two-stage asymmetric damper to yield a compromise between the conflicting performance measures. A composite performance index comprising the ride comfort and road holding measures with limit constraint on camber angle variation is formulated to seek optimal damper parameters. The results are presented so as to yield design guidance for synthesis of asymmetric dampers.

Full text
Abstract:
A non-monotonic meanline angle distribution technique with local negative camber is applied to a transonic rotor blade from the hub area to tip with the inlet Mach number varying from subsonic to low supersonic. The blade passage area is controlled by the non-monotonic meanline angle distribution, which results in reduced peak Mach number and weakened or removed shock wave. The negative camber is used downstream of the throat and hence it does not affect the flow passing capability of the blade section. The design point efficiency is significantly increased and the stall margin at part speed is also improved. Detailed results are given in the paper.

Abstract:
Curved blade has been widely used to reduce the endwall loss, but there is no criterion for curved blade design. Relationship of the optimum curved blade generate line (stack line) and the inlet Mach number, solidity, aspect ratio and camber angle in a linear compressor cascade were researched by optimization method in present paper. The stack line is vertically symmetrical, composed of two third-order Bezier curves and a straight line. The results show that total pressure loss coefficient decreases with the curved height increasing in the present calculate conditions at the same curved angle, and the optimum curved height is 0.5. The total pressure loss coefficient variation with curved angle presents a approximate parabola line type at the same curved height, there is an optimum curved angle, at which the total pressure loss coefficient is minimal. The optimum curved angle variation with the cascade parameters. Optimum curved angle increases with the inlet Ma and camber angle increasing, optimum curved angle variation with inlet Ma shows a polynomial curve type, optimum curved angle varied linearly with camber angle increasing. Optimum curved angle has little changes with solidity and aspect ratio increasing, optimum curved angle is about 6.5° in present conditions, but optimum curved angle will change with the blade loading. The benefit of the optimum curved blade increases with the inlet Mach number and camber angle increasing, and it has little change with solidity and aspect ratio increasing.

Abstract:
Ours is an age of pervasive political turbulence, and the scale of the challenge requires new thinking on politics as well as public ethics for our world. In Western countries, the specter of Islamophobia, alt-right populism, along with racialized violence has shaken public confidence in long-secure assumptions rooted in democracy, diversity, and citizenship. The tragic denouement of so many of the Arab uprisings together with the ascendance of apocalyptic extremists like Daesh and Boko Haram have caused an even greater sense of alarm in large parts of the Muslim-majority world. It is against this backdrop that M.A. Muqtedar Khan has written a book of breathtaking range and ethical beauty. The author explores the history and sociology of the Muslim world, both classic and contemporary. He does so, however, not merely to chronicle the phases of its development, but to explore just why the message of compassion, mercy, and ethical beauty so prominent in the Quran and Sunna of the Prophet came over time to be displaced by a narrow legalism that emphasized jurisprudence, punishment, and social control. In the modern era, Western Orientalists and Islamists alike have pushed the juridification and interpretive reification of Islamic ethical traditions even further. Each group has asserted that the essence of Islam lies in jurisprudence (fiqh), and both have tended to imagine this legal heritage on the model of Western positive law, according to which law is authorized, codified, and enforced by a leviathan state. “Reification of Shariah and equating of Islam and Shariah has a rather emaciating effect on Islam,” Khan rightly argues. It leads its proponents to overlook “the depth and heights of Islamic faith, mysticism, philosophy or even emotions such as divine love (Muhabba)” (13). As the sociologist of Islamic law, Sami Zubaida, has similarly observed, in all these developments one sees evidence, not of a traditionalist reassertion of Muslim values, but a “triumph of Western models” of religion and state (Zubaida 2003:135). To counteract these impoverishing trends, Khan presents a far-reaching analysis that “seeks to move away from the now failed vision of Islamic states without demanding radical secularization” (2). He does so by positioning himself squarely within the ethical and mystical legacy of the Qur’an and traditions of the Prophet. As the book’s title makes clear, the key to this effort of religious recovery is “the cosmology of Ihsan and the worldview of Al-Tasawwuf, the science of Islamic mysticism” (1-2). For Islamist activists whose models of Islam have more to do with contemporary identity politics than a deep reading of Islamic traditions, Khan’s foregrounding of Ihsan may seem unfamiliar or baffling. But one of the many achievements of this book is the skill with which it plumbs the depth of scripture, classical commentaries, and tasawwuf practices to recover and confirm the ethic that lies at their heart. “The Quran promises that God is with those who do beautiful things,” the author reminds us (Khan 2019:1). The concept of Ihsan appears 191 times in 175 verses in the Quran (110). The concept is given its richest elaboration, Khan explains, in the famous hadith of the Angel Gabriel. This tradition recounts that when Gabriel appeared before the Prophet he asked, “What is Ihsan?” Both Gabriel’s question and the Prophet’s response make clear that Ihsan is an ideal at the center of the Qur’an and Sunna of the Prophet, and that it enjoins “perfection, goodness, to better, to do beautiful things and to do righteous deeds” (3). It is this cosmological ethic that Khan argues must be restored and implemented “to develop a political philosophy … that emphasizes love over law” (2). In its expansive exploration of Islamic ethics and civilization, Khan’s Islam and Good Governance will remind some readers of the late Shahab Ahmed’s remarkable book, What is Islam? The Importance of Being Islamic (Ahmed 2016). Both are works of impressive range and spiritual depth. But whereas Ahmed stood in the humanities wing of Islamic studies, Khan is an intellectual polymath who moves easily across the Islamic sciences, social theory, and comparative politics. He brings the full weight of his effort to conclusion with policy recommendations for how “to combine Sufism with political theory” (6), and to do so in a way that recommends specific “Islamic principles that encourage good governance, and politics in pursuit of goodness” (8).
