“Patterns” of Threshold Spaces in the Historical City of Jeddah explores the meaning of threshold spaces and investigates the relationship between the public spaces and residential units in the historical city of Jeddah, Saudi Arabia, while at the same time revisiting Christopher Alexander’s theory in his canonical 1977 book, A Pattern Language. This book questions and analyses “patterns” relating to the cultural, social, and environmental particularities of Jeddah, with special attention paid to the effect of gender segregation in the city’s urban configuration. It discusses the extension that has been undertaken through testing a concept from the urban design theory of the West (the United States and Canada) and applying it to an Islamic city to find patterns in four different scales, which form the basis of the investigation (body, building, street, and city). Empirical methods have been used in the context of historical Jeddah, through which patterns are investigated using different approaches for the different scales. The book aims to explore the meaning of threshold spaces in old Jeddah. Furthermore, it shows that there are eighteen patterns of threshold spaces in the old town: patterns that are solely related to this specific case study, as well as modified patterns to the ones explored by Christopher Alexander. This book shall allow not only a better understanding of the relationship between housing and the historical city but also an exploration of the role of the threshold space in shaping the old city of Jeddah. It will be of interest to researchers, students of architecture, urban planning and anthropology studies, and people involved in cultural heritage, both academics and practitioners.

What is a threshold space? A prelude, an intermediate space, a barrier? Inside or outside? The threshold space is all of these, usually even at the same time. He lives on the spatial ambivalence between opening and closing and at the same time creates the expectation of what is to come. Till Boettger has dealt in teaching and research projects closely with the architectural staging of arrival and reception. His book is a collection of exemplary phenomenological analyzes of spatial transitions in historical and modern cultural buildings by renowned architects. It also develops a methodology to optimize threshold rooms in all construction projects. In addition to a balance that can generate an exciting space, there is also primarily the temporal sequence of experiencing determining. Threshold spaces are shown here in their role as a spatial agent: they receive and bid farewell.

“In the beginning” so goes many a great story. These familiar words beckon us across a threshold, often transporting us into unknown worlds and novel experiences. So too our lives are filled with many such “beginnings” – new jobs, relationships, adventures, and even the inception of life itself. Each of these “threshold experiences” not only introduces us to new domains, but also draws us into the realities of archetypal fields. Learning to creatively interact with these prefigured, a priori fields can allow us rich access to sources of eternal wisdom. Jungian analyst Michael Conforti’s examination of the initial clinical interview as a “threshold experience” shows that the same archetypal processes responsible for the generation of life itself also shape patient- therapist relationships, creating fascinating, highly patterned dynamics. These powerful fields structure events so that core issues in clients’, and often even therapists’, lives are re-enacted in the therapeutic setting, with remarkable fidelity to the archetypal field within which each is embedded. Conforti’s deft weaving together of psychological and scientific theory, dream analysis, and clinical vignettes elucidates the ways that the psyche entrains both client and therapist into a synchronized pattern. An understanding of the role of the Self in this process reveals the profound meaning and purpose that can be gleaned from careful attention to the communications occurring during the early phase of the therapeutic dialogue. Drawing from the fields of Jungian psychology, biology, quantum physics, and the new sciences, the author provides a unique lens for viewing the central archetypal dynamics operating within an individual life. His findings demonstrate how past experiences not only shape the initial stages of therapy, but also allow us to understand the future trajectory of treatment. This important study confirms C.G. Jung’s assertion of the need for an interdisciplinary perspective if we are to truly comprehend the workings of the psyche.

Excitable media comprise a class of models for a wide range of physical, chemical, and biological systems that exhibit spontaneous formation of spatial patterns. Patterns in Excitable Media: Genesis, Dynamics, and Control explores several aspects of the dynamics of such patterns-in particular their evolution upon interaction with structural and fun

Observing the environment and recognising patterns for the purpose of decision making is fundamental to human nature. This book deals with the scientific discipline that enables similar perception in machines through pattern recognition (PR), which has application in diverse technology areas. This book is an exposition of principal topics in PR using an algorithmic approach. It provides a thorough introduction to the concepts of PR and a systematic account of the major topics in PR besides reviewing the vast progress made in the field in recent times. It includes basic techniques of PR, neural networks, support vector machines and decision trees. While theoretical aspects have been given due coverage, the emphasis is more on the practical. The book is replete with examples and illustrations and includes chapter-end exercises. It is designed to meet the needs of senior undergraduate and postgraduate students of computer science and allied disciplines.
