Reflectometry Model of a Self-Calibrating Integrating Sphere
ISBN: 9783843360166 / Angielski / Miękka / 136 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Reported measurement methods for determining emissivity, reflectivity and absorptivity of materials have tended to disregard contributions arising from total internal reflections of the primary signal. In this book, a self-calibrating mathematical model has been developed that takes care of contributions from internally reflected radiation. The model considers both specimen and standard samples in the form of a flat strip placed simultaneously in their respective sphere apertures as incident laser radiation tuned at 900nm is alternately targeted at them. Emissivity is found to depend on...

Flow Regimes, Thermal and Humidity Patterns in Archaeological Tombs
ISBN: 9783843370226 / Angielski / Miękka / 172 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The tombs of the kings in Valley of the Kings, Luxor, are considered to be one of the tourism industry's bases in Egypt due to their uniqueness all over the world. Hence, they should be preserved from the different factors that might cause harm for their wall paintings. One of these factors is the excessive relative humidity as it increases the bacteria and fungus activity inside the tomb in addition to its effect on the mechanical and physical properties of materials. The current research aims to study the mechanical ventilation systems effect on airflow pattern as well as temperature and...

Hybrid Mechatronic Systems
ISBN: 9783843368193 / Angielski / Miękka / 248 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. To further improve performances of m systems, mechatronics offers some opportunities. Traditionally, mechatronics deals with how to integrate mechanics and electronics without a systematic approach. This book generalizes the concept of mechatronics into a new concept called hybrid mechatronic system. A hybrid mechatronic system is a system where two or more elements combine to play at least one of the roles such as sensor, actuator, or control mechanism, and contribute to the system behaviour (e.g., trajectory tracking). The common feature with the hybrid mechatronic system is thus the...

Progress in Low-Dimensional Chaos
ISBN: 9783843371070 / Angielski / Miękka / 104 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The field of chaotic dynamics has grown highly nonlinearly in the past few decades. Major progress occurred in traditional areas such as bifurcations, crises, basin boundaries, strengthening the mathematical foundations. New topics such as control and synchronization of chaos have emerged, addressing more practical questions. This book has a bit of both, addressing the initiates in low-dimensional chaos, from graduate students to researchers. First, we discuss the topic of phase synchronization of chaos. This phenomenon results from weak interactions between dynamical systems and...

Mathematical analysis of selected problems from fluid thermomechanics
ISBN: 9783844315356 / Angielski / Miękka / 188 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. A complete study of heat conducting viscous flows presents several nonlinearities: the convections, the Joule effect and energy dependent conductivity and viscosities. Adopting the general thermodynamics process, the constitutive relations for the Cauchy stress tensor and the heat flux are nonlinear with p and q coercivity parameters, respectively, when non- Newtonian fluids are taken care of. We investigate what we call the (p-q) coupled fluid-energy system. We deal with the initial and boundary value problems of (p-q) coupled fluid-energy systems under Dirichlet-Newton boundary...

Numerical Modeling and Control of the Mold Casting Process
ISBN: 9783844310191 / Angielski / Miękka / 88 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The improvement of the cast part quality, both as far as the geometric precision and mechanical properties are concerned, is an important desiderate for researchers. There is a twofold aim: on the one hand, the reduction of the costs related to the cast part mechanical machining (in order to do this, the dimensional errors of the cast parts should be reduced to diminish the machining allowance with the machining processes) and, on the other hand, a high level of the cast part strength during functioning, by obtaining a proper crystalline structure during melt material ...

Task Oriented Simulation and Control of a Wheelchair Mounted Robotic Arm
ISBN: 9783844328479 / Angielski / Miękka / 152 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The main objective of the work presented in this book is to improve the control structure for the new Wheelchair Mounted Robotic Arm (WMRA) to include new algorithms for optimized task execution; that is, making the WMRA a modular task oriented mobile manipulator. The main criterion to be optimized is the fashion in which the wheelchair approaches a final target as well as the starting and final orientation of the wheelchair. This is a novel approach in non-holonomic wheeled manipulators that will help in autonomously executing complex activities of daily living (ADL) tasks. The WMRA is a 9...

Modelling dynamics of multibody systems
ISBN: 9783838310404 / Angielski / Miękka / 132 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Research in multibody systems has been growing rapidly in parallel with developments in computer sophistication since this has enabled complex real systems to be analysed more easily and quickly. One of the most difficult problems in modelling multibody systems is flexibility, which requires more simplifying assumptions than other phenomena. This monograph explains how homogenous transformations can be used to model kinematic chains with both rigid and flexible links. Flexible links are modelled using three approaches: both the classical and modified rigid finite element method as well as...

Inflow Generation for Large-Eddy Simulation
ISBN: 9783843365208 / Angielski / Miękka / 100 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. When simulating turbulent flows using Large-Eddy Simulations (LES) or Direct Numerical Simulations (DNS), imposing correct instantaneous flow quantities at the inflow boundary is a challenge. Inflow fluctuations need to preserve the turbulent characteristics of the upstream flow that is not simulated. The inflow conditions are rendered more physically meaningful by rescaling the instantaneous solution from an internal plane normal to the wall located inside the computational domain using self-similarity of the boundary layer velocity profile at each time step of the simulation. Thus the...

Phase transitions of long-chain n-alkanes at interfaces
ISBN: 9783838300368 / Angielski / Miękka / 140 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Nucleation of an emerging phase has long been one of the major research fields in Science and Engineering. In many cases, interfaces play crucial roles by providing (heterogeneous nucleation) or suppressing (homogeneous nucleation) potential nucleation sites for bulk phase transitions. In this book, an experimental study of phase transitions of long-chain n-alkanes induced by the effect of interfaces is described. In particular, the effect of inert and molecularly smooth solid surfaces and that of gas interfaces are investigated in detail. Given that the vast majority of phase transitions...
