Compressive Sampling Using a Pushframe Camera

The recently described pushframe imager, a parallelized single pixel camera capturing with a pushbroom-like motion, is intrinsically suited to both remote-sensing and compressive sampling. It optically applies a 2D mask to the imaged scene, before performing light integration along a single spatial axis, but previous work has not made use of the architecture's potential for taking measurements sparsely. In this paper we develop a strongly performing static binarized noiselet compressive sampling mask design, tailored to pushframe hardware, allowing both a single exposure per motion time-step, and retention of 2D correlations in the scene. Results from simulated and real-world captures are presented, with performance shown to be similar to that of immobile and hence inappropriate for satellite use whole-scene imagers. A particular feature of our sampling approach is that the degree of compression can be varied without altering the pattern, and we demonstrate the utility of this for efficiently storing and transmitting multi-spectral images.

RETRACTED: Simulation of swimming sports image recognition based on multi-core processor and dynamic image sampling

Abstract Human understanding of human movement is one of the most important areas of research activities. In recent years, the use of RGB-D movement recognition data has raised concerns. With artificial intelligence development, the depth of learning technology has made great success in computer vision. A variety of application scenarios and real-time constraints computer vision applications spurred on computer architecture conducted extensive research. These studies take advantage of image processing algorithms and computer vision functions to maximize and improve efficiency through the hardware's scalability. Growth, programmable computing power, and multi-core architecture's potential to accelerate parallel image processing and computer vision algorithms provide a broad prospect. Conduct a new study to discover the unique attributes of three computer vision algorithms that are widely used and determine the optimal computing architecture for each algorithm. Advantages of parallel processing hardware to provide modern programmable graphics data and the thread of instructions, which is significantly faster than the standard CPU implementation.

Illustrating architecture: the spatio-temporal dimension of Gerrit Rietveld's representations of the Schröder House

This paper examines two axonometric projections by Gerrit Rietveld that portray the house designed for and in collaboration with Truus Schröder-Schräder.1 Utilising specific attributes of the technique of the axonometric, Rietveld developed concepts of architecture that were both abstract and yet contingent on architecture's material requirements and its function as habitation. Rather than using text to explain the ideas behind the house Rietveld chose drawing, and more specifically the technique of the axonometric, to characterise complex strategies that were fundamental to its distinctive architectural concepts.2 Axonometric techniques, in maintaining dimensional accuracy, can provide an understanding of architectural design that, unlike perspective or photography, avoids placing the viewer's experience as the privileged interpretive paradigm.3 For Rietveld, illustration clearly situated his expectations for architecture's signification beyond its physical presence. His exploration of architecture's potential through the axonometric could also have been influenced by his reaction to popular theories coming from ‘scientific’ explorations of perceptual space and to artists like Piet Mondrian who had criticised architecture for its inability to come to terms with ‘new representation’.4 These two Rietveld illustrations provoke specific understandings of architecture by privileging the abstract conceptual relationships that can be developed between spatial and auxiliary domestic elements of a dwelling. For the discipline of architecture, Rietveld provided an alternative concept for architecture based scientifically on a system of logical equivalency. For architecture this suggested a correlation formed between abstract geometries of form with the contingencies of material habitation.

Enabling Scalable High-Performance Systems with the Intel Omni-Path Architecture

The Intel Omni-Path Architecture (Intel OPA) is designed to enable a broad class of computations requiring scalable, tightly coupled CPU, memory, and storage resources. Integration between the Intel OPA family and Intel CPUs enable improvements in system-level packaging and network efficiency. When coupled with the new open standard APIs developed by the OpenFabrics Alliance (OFA) Open Fabrics Initiative (OFI), the Intel OPA family is optimized to provide low latency, high bandwidth, and a high message rate. Intel OPA enables a multigeneration, scalable fabric through innovations including link layer reliability, extended fabric addressing, and optimizations for high-core-count CPUs. Intel OPA also provides optimizations to address datacenter needs, including link-level traffic flow optimization, to minimize jitter for high-priority packets, partitioning support, quality-of-service support, and a centralized fabric management system. Basic performance metrics from first-generation host fabric interface and switch implementations demonstrate the new fabric architecture's potential.

CONMan

Networks are hard to manage and in spite of all the so called holistic management packages, things are getting worse. We argue that the difficulty of network management can partly be attributed to a fundamental flaw in the existing architecture: protocols expose all their internal details and hence, the complexity of the ever-evolving data plane encumbers the management plane. Guided by this observation, in this paper we explore an alternative approach and propose Complexity Oblivious Network Management (CONMan), a network architecture in which the management interface of data-plane protocols includes minimal protocol-specific information. This restricts the operational complexity of protocols to their implementation and allows the management plane to achieve high level policies in a structured fashion. We built the CONMan interface of a few protocols and a management tool that can achieve high-level configuration goals based on this interface. Our preliminary experience with applying this tool to real world VPN configuration indicates the architecture's potential to alleviate the difficulty of configuration management.

A scalable LDPC decoder ASIC architecture with bit-serial message exchange

We present a scalable bit-serial architecture for ASIC realizations of low-density parity check (LDPC) decoders. Supporting the architecture's potential, we describe a decoder implementation for a (256,128) regular-(3,6) LDPC code that has a decoded information throughput of 250 Mbps, a core area of 6.96 mm 2 in 180-nm 6-metal CMOS, and an energy efficiency of 7.56 nJ per uncoded bit at low signal-to-noise ratios. The decoder is fully block-parallel, with all bits of each 256-bit codeword being processed by 256 variable nodes and 128 parity check nodes that together form an 8-stage iteration pipeline. Extrinsic messages are exchanged bit-serially between the variable and parity check nodes to significantly reduce the interleaver wiring. Parity check node processing is also bit-serial. The silicon implementation performs 32 iterations of the min-sum decoding algorithm on two staggered codewords in the same pipeline. The results of a supplementary layout study show that the reduced wiring congestion makes the decoder readily scaleable up to the longer kilobit-size LDPC codewords that appear in important emerging communication standards.

A biologically inspired modular VLSI system for visual measurement of self-motion

We introduce a biologically inspired computational architecture for small-field detection and wide-field spatial integration of visual motion based on the general organizing principles of visual motion processing common to organisms from insects to primates. This highly parallel architecture begins with two-dimensional (2-D) image transduction and signal conditioning, performs small-field motion detection with a number of parallel motion arrays, and then spatially integrates the small-field motion units to synthesize units sensitive to complex wide-field patterns of visual motion. We present a theoretical analysis demonstrating the architecture's potential in discrimination of wide-field motion patterns such as those which might be generated by self-motion. A custom VLSI hardware implementation of this architecture is also described, incorporating both analog and digital circuitry. The individual custom VLSI elements are analyzed and characterized, and system-level test results demonstrate the ability of the system to selectively respond to certain motion patterns, such as those that might be encountered in self-motion, at the exclusion of others.

California modernism and the Eichler homes

This paper describes how the Eichlers were one of a very few examples of Modern Movement architecture in the American commercial housing market, and probably the most successful. There were many efforts particularly by architects, during the postwar period, to open up the merchant builder industry to architectural design, but after prying open a narrow slice of the market for a few years the developers took over once again, and the Eichlers were sealed in time, leaving us with a tantalising image of Modern Architecture's potential to improve the quality of everyday life.
