Abstract:
In the contact area of offset, a relative slide occurs between the surface of plate cylinder and blanket cylinder, which changes the print image and influences the printing quality. The relative slide in the cylinders’ rolling process is investigated, and the determination rule of cylinders’ geometric parameters of offset press is proposed. The results show that the relative slide is minimization under the condition that the compression of elastic cylinder radius is 0.2 times bigger than that of rigid cylinder radius, and the deformation of print image and dot gain both are minimization. The results provide theoretical direction for accurate determination of cylinder radius of offset press.

Abstract:
In order to obtain greater accuracy in simulation, more sophisticated models are often required. When it comes to the torsional vibration of reciprocating mechanisms the effect of inertia variation is very important. It has been shown that the inclusion of this variation increases model accuracy for both single-cylinder and multi-cylinder engine torsional vibration predictions. Recent work by the present authors has revealed that piston-to-cylinder friction may modify an engine's ‘apparent’ inertia function. Kinematic analysis also shows that the piston side force and the dynamic piston-to-cylinder friction are interdependent. This has implications for engine vibration modelling. Most modern engines employ a gudgeon pin offset, and there is a growing interest in pursuing large crank offsets; hence, the effect of these on inertia variation is also of interest. This paper presents the derivation of the inertia function for a single engine mechanism, including both piston-to-cylinder friction and crank or gudgeon pin offset, and investigates the effect of each through predictions. The effect of crank offset on the variable inertia function is also verified by experiment.

Abstract-Flow over two offset square cylinders in a confined channel is simulated for different Reynoldsnumber to reveal the forced convection heat transfer from the heated square cylinders to the ambientfluid. The bottom of the cylinder is maintained at constant temperature. The distance between thecylinder in normal direction as well as transverse direction are fixed as 2d and the blockage ratio is fixedas 0.167. Heat transfer from the cylinders to the ambient fluid as well as conducted within solid wallthrough conjugate interface boundary investigated in connection with Reynolds number are reportedfor both steady and periodic flow. Simulation is carried out for Reynolds number varies from 10 to100 for the fluid as air with Prandtl number as 0.71. The isotherm contours, local Nusselt number andaverage Nusselt number are reported for various Reynolds number. The stagnation zone results higherNusselt number than remaining walls and rear wall results lowest Nusselt number. The downstreamcylinder results higher Nusselt number than the upstream cylinder. The top and bottom surfaceNusselt number from upstream and downstream cylinder are not analogous to single cylinder placed ina channel.

Abstract:
Imbalance in torque generation leads to engine speed fluctuation. To improve the idle engine speed performance, the torque balancing control problem is addressed in this paper for multi-cylinder SI engines. To evaluate cylinder-to-cylinder imbalance, the average torque in ignition-event scale is introduced as controlled output, which enables a feedback control to be performed without measurement of instantaneous torque, and the individual spark advances are chosen as control inputs. A linear discrete time model with single input and single output is proposed to represent the dynamics of the imbalance, where a sequentially switching function is introduced to describe the spark advance signals delivered to each cylinder and the differences in torque generation caused by the individual cylinder characteristics are equivalently modelled as unknown offset in the inputs. An estimation algorithm with the proof of convergence is presented to provide on-line estimation of the unknown offset under the passivity assumption of the system. Furthermore, a feedback control law which combines the unknown offset estimation and the model predictive control is proposed. Finally, the unknown offset estimation and the feedback control approach are validated based on the experimental results carried out on a six-cylinder gasoline engine test bench.

Abstract:
Printing cylinder driven by helical gear is the basic requirements of the modern printing press. Helical gear transmission necessarily produces component force in axial. It brings about a small displacement in axial to the cylinder, that is, axial bounce. The axial placement is too small or too large during the printing process, which both will have harmful effects on printed matter. At the same time, the axial playing of the cylinder is one of the important performance standards to determine printing press. The modern high-speed printing press has a higher requirement on mechanic properties and axial bounce. We tested on the cylinders of press and analyzed on the placement of the cylinders in order to effectively master and control the displacement in axial in the case of the printing press running with high-speed. We chose a four-color offset press as the test objects and reasonably selected measurement points on the cylinder shaft end face. We collected vibration signals of the blanket cylinders, impress cylinders and transfer cylinders. Then obtain the placement in axial of the cylinders with quadrature method. Analysis shows that the higher the printing speed, the larger the placement of the same type cylinder in axial is, which shows that the placement of the cylinders in axial has something to do with the printing speed. At the same speed, the blanket cylinder have a larger placement in axial than impress cylinder and transfer cylinder. Which shows that the placement of the cylinders in axial has connection to the cylinder assembly structure. Test data accord well with the actual structure and assembling condition, which can be considered as the theoretical basis to control the placement of cylinder in axial.

Abstract:
This work introduced the structural characteristic and working principle of cylinder offset oil-free lubricated wobble-reciprocating compressor. A mathematical model of crank-link mechanism was setup. The influence of cylinder offset to side clearance, side pressure and friction power were discussed. It revealed that when the offset applied on suction stroke side, the peak value of side pressure in suction stroke was relatively low in comparison to that of the compression stroke. Low friction loss was hereby achieved; meanwhile the system’s sealability was deteriorated, due to the larger backlash between piston and cylinder during the compression process. Reverse trend was found when the offset moved to compression stroke side. The side pressure in suction stroke and the friction power increased, with the decrease of side pressure of compression process and the improvement of sealability.

Abstract:
A numerical study of the flow-induced vibration of two elastically mounted cylinders in tandem and staggered arrangements at Reynolds number $Re=200$ is presented. The cylinder centres are set at a streamwise distance of 1.5 cylinder diameters, placing the rear cylinder in the near-wake region of the front cylinder for the tandem arrangement. The cross-stream or lateral offset is varied between 0 and 5 cylinder diameters. The two cylinders are identical, with the same elastic mounting, and constrained to oscillate only in the cross-flow direction. The variation of flow behaviours is examined for static cylinders and for elastic mountings of a range of spring stiffnesses, or reduced velocity. At least seven major modes of flow response are identified, delineated by whether the oscillation is effectively symmetric, and the strength of the influence of the flow through the gap between the two cylinders. Submodes of these are also identified based on whether or not the flow remains periodic. More subtle temporal behaviours, such as period doubling, quasi-periodicity and chaos, are also identified and mapped. Across all of these regimes, the amplitudes of vibration and the magnitude of the fluid forces are quantified. The modes identified span the parameter space between two important limiting cases: two static bodies at varying lateral offset; and two elastically mounted bodies in a tandem configuration at varying spring stiffnesses. Some similarity in the response of extremely stiff or static bodies and extremely slack bodies is shown. This is explained by the fact that the slack bodies are free to move to an equilibrium position and stop, effectively becoming a static system. However, the most complex behaviour appears between these limits, when the bodies are in reasonably close proximity, and the natural structural frequency is close to the vortex shedding frequency of a single cylinder. This appears to be driven by the interplay between a series of time scales, including the vortex formation time, the advection time across the gap between the cylinders and the oscillation period of both bodies. This points out an important difference between this multi-body system and the classic single-cylinder vortex-induced vibration: two bodies in close proximity will not oscillate in a synchronised, periodic manner when their natural structural frequencies are close to the nominal vortex shedding frequency of a single cylinder.

A compact dielectric resonator antenna for ultra-wideband vehicular communication applications is proposed. Two cylindrical dielectric resonators are asymmetrically located with respect to the center of an offset rectangular coupling aperture, through which they are fed. Optimizing the design parameters results in an impedance bandwidth of 21%, covering the range from 5.9 to 7.32 GHz in the lower-band and a 53% relative bandwidth from 8.72 to 15 GHz in the upper-band. The maximum achieved gain is 12 dBi. Design details of the proposed antenna and the results of both simulations and experiment are presented and discussed.

Abstract:
The chapter aims to demonstrate that Seleucid writings from and about Babylon provide insight into the ways in which literature was used to construct and reflect practices of empire. The literature dealing with Babylonia is of special significance because of the important ideological position Babylon held in the Seleucid imagination. To unpack this point further, the chapter analyses the Borsippa Cylinder as Seleucid literature, by arguing that King Antiochus I combined motifs from Mesopotamian kingship and Hellenistic royal practices to create a narrative of Seleucid euergetism embedded in, rather than superimposed upon, Babylonian traditions of kingship. The second part of the chapter argues that the Babylonian elites reciprocated the king’s offer of benefaction by offering him the tradition of Babylonian kingship, and by extension, universal dominion. The chapter concludes by looking at Ptolemaic attempts to match Seleucid prowess in the field of indigenous history. It is argued that, just as Seleucid Berossus had responded to the Ptolemaic Hecataeus, Manetho provided a Ptolemaic-Egyptian version of history to match the history of Babylon by Berossus.

Abstract:
Two equal diameter ABS cylinders, offset from tandem, were subjected to uniform and sheared flows in a current tank at subcritical Reynolds numbers. Both tubes were filled with a saltwater solution to produce a specific gravity of 1.38. An accelerometer in each cylinder was used to measure the vortex-induced vibration response, which primarily varied between the third and seventh transverse bending modes. The cylinders were spaced at 3 to 20 diameters in the in-line direction and at 0, 0.5, and 1.0 diameter in the offset direction. Test results indicate that a downstream cylinder, for a pure tandem (no offset) configuration, experiences less vibration than the upstream cylinder when the upstream cylinder rms displacement is larger than about 0.35D. Offsets of 0.5 and 1.0 times the outside diameter produce lower vibration of the downstream cylinder relative to that of the upstream cylinder.

Abstract:
Transient two-dimensional negatively buoyant flow into a straight adiabatic baffle beneath an isothermal circular cylinder is numerically simulated. The surrounding fluid is considered infinite in extent and at constant temperature. Governing parameters are the baffle width and the offset of the entrance of the baffle beneath the center of the cylinder. Overall characteristics of the flow and entrainment of the surrounding fluid are found to be dependent on the baffle offset; however, the attachment length of the flow to the baffle wall is relatively insensitive to the offset. Heat transfer rates to the cylinder are calculated for various times for various baffle offsets. There is a weak dependence on baffle-offset distance with heat transfer rate.

Abstract:
Drillings and millings of cylinders are performed in operations on turning centers. Then, the drill holes are machined on the cylinder surfaces with offsets of the cutting positions from the workpiece axis. The paper presents an analytical model to predict the cutting force in drilling of cylinders. Three dimensional chip flow is interpreted as a piling of the orthogonal cuttings in the planes containing the cutting velocities and the chip flow velocities. In drilling, the chip flow models are made on the chisel and the lips. The chip flow directions are determined to minimize the cutting energies on the chisel and the lips. The workpiece model on the cylinder is defined by the cutting point with respect to the cylinder shape. The cutting force in drilling of a cylinder is compared with that in drilling of a plate. Then, the effect of the offset cutting points on the cutting force is discussed in terms of the resultant cutting force, which induces the machining error and the tool breakage.

Abstract:
Abstract In natural sedimentation, many particles of interest are both large and nonspherical. Some common particle types (e.g. naturally occurring aggregates) do not have a uniform mass distribution. As a result, the centers of mass and buoyancy are not co-located, leading to more complex settling dynamics. Here we investigated the orientation and terminal velocity of freely falling cylinders, in which the mass distribution was either constant (uniform-density, UD) or bipartite, undergoing a step function halfway along the length (compound-density, CD). Cylinders had relatively low aspect ratios (1 < AR < 4), and fell at intermediate Reynolds numbers (of order 100). The cylinders, initially horizontal, were released at the top of a tall hexagonal still-water tank, and imaged by a high-speed camera. Two low-speed cameras simultaneously captured 1) full cylinder trajectory and 2) landing position. We recorded the terminal velocity, fall orientation, and landing site of each cylinder. Results showed significant differences in the settling characteristics of uniform- vs. compound-density cylinders. UD cylinders of AR = 1 fell broadside initially, whereas AR = 1 CD cylinders fell vertically. However, both cases showed oscillation in cylinder orientation upon descent. UD cylinders with AR = 2 and AR = 4 consistently fell broadside, with minimal cylinder axis oscillation. CD cylinders with AR = 2 fell with two different modes. In mode 1, cylinders rotated 90° from their initial orientation before beginning to oscillate about the vertical axis. In mode 2, cylinder orientation remained constant at a slight angle from the horizontal. This mode was also observed in the CD AR = 4 cylinders, which fell at a constant (tilted) orientation angle and moved horizontally as they fell. The landing sites for all CD cylinders were biased toward the side of the target where the denser end of the cylinder was initially oriented, whereas UD cylinders landed in a uniform distribution around the tank center. In general, cylinders with the smallest vertical projected area fell with the greatest terminal velocity; however, the mechanisms controlling orientation remain unclear. Our results have important implications for predicting the settling behavior of naturally-occurring particles, and lay the groundwork for further study of particles settling in complex flows such as turbulence. Given our results in still water, the interplay between the buoyant torques created by the offset between the center of mass and center of volume are likely to strongly impact particle motion in turbulence.

Abstract:
The ring geometry, its assembly load and its mechanical and thermal properties are factors that influence engine performance. The ring dynamics is greatly influenced by piston secondary motions that depend upon the piston geometry, piston pin offset, its center of gravity (C.G.) location and piston-liner clearance. The engine is simulated to study the rings motion in axial, radial direction and the gap areas are calculated to estimate blowby and compared with experimental results. This approach to engine design reduces the conceptual design-to-development cycle time and reduces the need of extensive engine testing for evaluating ring performance.
