Abstract:
More complex distributed and intelligent systems which relate to economy, ecology, communi-cations, security and defense, and cover both terrestrial and celestial environments are being developed. Their efficient management, especially in dynamic and unpredictable situations, needs serious investigations and development in scientific and technological areas. Their tradi-tional representations as parts operating by certain algorithms and exchanging messages are be-coming inadequate as such systems need much stronger integration to operate as holistic organ-isms pursuing global and often varying goals. This paper is focused on a completely different paradigm for organization and management of large dynamic and distributed systems. This par-adigm extends and transforms the notion of an algorithm for the description of knowledge pro-cessing logic. Moreover, it allows it to exist, propagate and operate as an integral whole in any distributed spaces which may constantly change their volumes and structures. Taking into con-sideration some organizational features related to dangerous viruses, as well as recent pandem-ics, this ubiquitous Spatial Grasp (SG) model is presented in the paper at philosophical and im-plementation levels, together with the introduction of special spatial charts for its exhibition and studies, which extend traditional algorithmic flowcharts towards working directly in dis-tributed spaces. Utilization of this model for the creation of resultant Spatial Grasp Technology and its basic Spatial Grasp Language, already described in details in numerous publications, is briefed as well. Elementary examples of dealing with distributed networks, collective human-robotic behavior, removal of space debris by a constellation of cleaning satellites and simulat-ing the spread of virus and vaccination against it explain SG advantages over traditional system organizations.

Abstract:
The pattern is everything around us. It can represent the world’s regularity, a human-made design, a model, plan, diagram, a standard way of modeling, acting and thinking, a distinctive style or form, a combination of qualities and tendencies, etc. That is why the theory, research, and practical works on patterns are so important for different scientific and technological fields, having also stimulated the preparation and writing of the current paper. The paper reviews existing works on patterns, grouping them by different categories, and briefs the developed Spatial Grasp Model and Technology (SGT) and its Spatial Grasp Language (SGL) with the distributed networked implementation, which provide effective distributed solutions in systems management, control, and simulation by active self-spreading patterns. The article shows how practical patterns can be expressed in SGL, including regular patterns, patterns of concrete objects, and different pattern-based management solutions like coordinating transport columns, finding distributed zone coordinates, and spatial tracking of mobile objects. It also gives network examples of distributed pattern recognition and matching with the use of self-propagating active network templates reflecting images to be found. The paper provides a classified summary of the investigated use of SGL for pattern operations in different areas, which includes descriptive patterns, creative patterns, patterns as spatial processes, pattern recognition, self-matching patterns, combined patterns, cooperating and conflicting patterns, psychological patterns, and recursive patterns. The work concludes with the belief that SGL can be used as a real, very effective, and compact language for pattern representation and operations, and SGT should contribute to the pattern theory and resultant technologies.

Abstract:
The paper outlines the features of the spatial planning systems worldwide, on different continents, based on countries where legislative frameworks for the planning and methodology of preparing and implementing planning documents are defined. In order to define global features of a spatial planning systems it is necessary to address several issues: the implementation of sustainability principles, the development of regional planning, the importance of an urban planning approach, management system, implementation problems, participation, the share of strategic spatial planning and transnational cooperation, etc. The determination of the planning system by numerous and various factors influenced the different degree of development of the planning process. In many countries, planning practice faces problems associated with the disrespect of the law, corruption and illegal land use, resolving regional development imbalances in almost all countries etc. At a global level, addressing environmental issues is becoming a dominant goal in most planning systems.

Abstract:
The basis of systems considered in this article is a self-focusing antenna array, consisting of bars with 2 * m receiving antenna elements located equidistantly in each of them. The description and results of preliminary mathematical modeling of an adaptive antenna lattice with a possibility of realization of functions are provided in her spatially-frequency or spatially-code allocation and tracking of signals. The results of modeling of a linear lattice which have confirmed a possibility of reliable allocation of one of two the coded signals influencing her are given in rather wide dynamic range of their entrance levels. Similar systems can find application in satellite and land systems of a radio communication. The use of such systems increases the energy potential of radio links and reduces interference between signals.

Abstract:
This thesis investigates the conceptual and methodological issues for the development of Intelligent Spatial Decision Support Systems (ISDSS). These are spatial decision support systems (SDSS) integrating intelligent systems techniques (Genetic Algorithms, Neural Networks, Expert Systems, Fuzzy Logic and Nonlinear methods) with traditional modelling and statistical methods for the analysis of spatial problems. The principal aim of this work is to verify the feasibility of heterogeneous systems for spatial decision support derived from a combination of traditional numerical techniques and intelligent techniques in order to provide superior performance and functionality to that achieved through the use of traditional methods alone. This thesis is composed of four distinct sections: (i) a taxonomy covering the employment of intelligent systems techniques in specific applications of geographical information systems and SDSS; (ii) the development of a prototype ISDSS; (iii) application of the prototype ISDSS to modelling the spatiotemporal dynamics of high technology industry in the South-East of England; and (iv) the development of ISDSS architectures utilising interapplication communication techniques. Existing approaches for implementing modelling tools within SDSS and GIS generally fall into one of two schemes - loose coupling or tight coupling - both of which involve a tradeoff between generality and speed of data interchange. In addition, these schemes offer little use of distributed processing resources. A prototype ISDSS was developed in collaboration with KPMG Peat Marwick's High Technology Practice as a general purpose spatiotemporal analysis tool with particular regard to modelling high technology industry. The GeoAnalyser system furnishes the user with animation and time plotting tools for observing spatiotemporal dynamics; such tools are typically not found in existing SDSS or GIS. Furthermore, GeoAnalyser employs the client/server model of distributed computing to link the front end client application with the back end modelling component contained within the server application. GeoAnalyser demonstrates a hybrid approach to spatial problem solving - the application utilises a nonlinear model for the temporal evolution of spatial variables and a genetic algorithm for calibrating the model in order to establish a good fit for the dataset under investigation. Several novel architectures are proposed for ISDSS based on existing distributed systems technologies. These architectures are assessed in terms of user interface, data and functional integration. Implementation issues are also discussed. The research contributions of this work are four-fold: (i) it lays the foundation for ISDSS as a distinct type of system for spatial decision support by examining the user interface, performance and methodological requirements of such systems; (ii) it explores a new approach for linking modelling techniques and SDSS; (iii) it investigates the possibility of modelling high technology industry; and (iv) it details novel architectures for ISDSS based on distributed systems.

Abstract:
Errors are inherent to all spatial datasets and give rise to a level of uncertainty in the final product of a geographic information system (GIS). There is growing recognition that the uncertainty associated with spatial information should be represented to users in a comprehensive and unambiguous way. However, the effects on decision-making of such representations have not been thoroughly investigated. Studies from the psychological literature indicate decision-making biases when information is uncertain. This study explores the effects of representing spatial uncertainty, through an examination of how decision-making may be affected by the introduction of thematic uncertainty and an investigation of the effects of different representations of positional uncertainty on decision-making.
Two case studies are presented. The first of these considers the effects on decision-making of including thematic uncertainty information within the context of an airport siting decision task. An extremely significant tendency to select a zone for which the thematic classification is known to be of high certainty was observed. The reluctance to select a zone for which the thematic classification is of low certainty was strong enough to sometimes lead to decision-making that can only be described as irrational.
The second case study investigates how decision-making may be affected by different representations of positional uncertainty within the context of maritime navigation. The same uncertainty information was presented to participants using four different display methods. Significant differences in their decisions were observed. Strong preferences for certain display methods were also exhibited, with some representations being ranked significantly higher than others.
The findings from these preliminary studies demonstrate that the inclusion of uncertainty information does influence decision-making but does not necessarily lead to better decisions. A bias against information of low certainty was observed, sometimes leading to the making of irrational decisions. In addition, the form of uncertainty representation itself may affect decision-making. Further research into the effects on decision-making of representing spatial uncertainty is needed before it can be assumed that the inclusion of such information will lead to more informed decisions being made.

Abstract:

Recent advances in biology have shown that proteins and genes often interact probabilistically. The resulting effects that arise from these stochastic dynamics differ significantly than traditional deterministic formulations, and have biologically significant ramifications. This has led to the development of computational models of the discrete stochastic biochemical pathways found in living organisms. These include spatial stochastic models, where the physical extent of the domain plays an important role; analogous to traditional partial differential equations.

Simulation of spatial stochastic models is a computationally intensive task. We have developed a new algorithm, the Diffusive Finite State Projection (DFSP) method for the efficient and accurate simulation of stochastic spatially inhomogeneous biochemical systems. DFSP makes use of a novel formulation of Finite State Projection (FSP) to simulate diffusion, while reactions are handled by the Stochastic Simulation Algorithm (SSA). Further, we adapt DFSP to three dimensional, unstructured, tetrahedral meshes in inclusion in the mature and widely usable systems biology modeling software URDME, enabling simulation of the complex geometries found in biological systems. Additionally, we extend DFSP with adaptive error control and a highly efficient parallel implementation for the graphics processing units (GPU).

In an effort to understand biological processes that exhibit stochastic dynamics, we have developed a spatial stochastic model of cellular polarization. Specifically we investigate the ability of yeast cells to sense a spatial gradient of mating pheromone and respond by forming a projection in the direction of the mating partner. Our results demonstrates that higher levels of stochastic noise results in increased robustness, giving support to a cellular model where noise and spatial heterogeneity combine to achieve robust biological function. This also highlights the importance of spatial stochastic modeling to reproduce experimental observations.

Full text
Abstract:
Spatial light modulators (SLMs) play a key role for the development of programmable optical systems in information processing [3]. Electrically addressable SLMs are of special interest since they can be used to implement computer-generated transmission functions. Such a function is typically represented in a computer by a two-dimensional discrete data structure and can be dynamically mapped onto the pixelated micro-structures of the SLM. This mapping can be interpreted as a computer memory access where a section of the computer memory is copied to the SLM in order to modulate an illumination wave. Consequently, the SLM is an optical storage with an electrical write-in and an optical read-out mechanism. In an optical system the read-out of an SLM is performed in parallel and can be used to realize specified functions. The function of an optical system can be defined either by its system function or its input/output-behavior. Evidently, the capability of an SLM to realize optical functions depends on its storage characteristics [4, 5, 6].

Full text
Abstract:
Optically addressable spatial light modulators (OASLM's) are not only of use for the introduction of an incoherent intensity distribution to a coherent optical system, but also to realize optical image processing and storage if the same coherent beam is used to write and to read out the OASLM. In our contribution we report investigations on several optical systems, where the information that was read out coherently from a OASLM is processed by an optical system and then fed back to the rear side of the OASLM. Similar systems have been described in the literature for example to compensate wavefront aberrations in adaptive optics [1], or as a Fabry-Perot type OASLM with internal feedback [2]. We want to demonstrate the image processing and storage capabilities of such systems and will show how both amplitude and phase of a beam can be used for the processing.

Full text
Abstract:
Free-space optoelectronic systems continue to progress towards higher density interconnects (thousands of links) operating at high speeds (Gbit/sec) in small feature-size CMOS technology (0.5 μm and less). The interconnection density in a free-space system is limited by the power dissipation of the interconnects. This limit occurs when the system reaches the maximum power dissipation per unit area dictated by the cooling technology. Minimizing the power dissipation in the interconnects enables a system designer to maximize the interconnect density at a given bit-rate, or similarly, to maximize the bit-rate for a given interconnect density. Since the interconnect density is related to the system operating bit-rate through the power dissipation, a useful figure of merit is their product - the aggregate bandwidth (AGBW) per unit area. By minimizing the power per link over a range of bit-rates, the conditions which maximize the AGBW per unit area can be ascertained.

Abstract:
Multichannel arrays of phase modulators are attractive as fast, high resolution random-access beam deflectors and can find direct application to such areas as projection display and programmable optical interconnects. Because of their similarity to a stepped-phase diffractive optical element (DOE) we call these devices programmable DOEs. Several forms of programmable DOEs for beam steering have been reported including a compact liquid crystal based system1 and faster electrooptic based devices.2-3 The electrooptic (E-O) systems permit much faster switching rates but at the cost of higher drive voltages. We have focused our efforts on the development of an electooptic programmable DOE based on lanthanum-modified lead zirconate titanate (PLZT). A simple device of this type is shown in Fig. 1 (from Ref. 3).

Full text
Abstract:
Spatial light modulators (SLM) are utilized in systems which compensate for distortion of a laser beam caused by transmission through a distorting medium. The Northrop Grumman linear beam cleanup system [1] uses an SLM to modify the phase front of the input beam to cancel the phase changes produced along the transmission path. At longer wavelengths these phase changes may not be achievable with current liquid crystal or lead lanthanum zirconate titanate (PLZT) modulators. High laser power levels may also produce adverse effects in these materials if operated in transmission mode. The silicon SLM (Si-SLM) produces a phase change by reflection of the laser from the surface of moveable pixels. The all silicon construction of the Si-SLM reduces the effects of temperature changes on the flatness of the reflecting surface.
