Exact and Approximate Squarers for Error-Tolerant Applications
Get PDFApproximate computing is considered an innovative paradigm with wide applications to high performance and low power systems. These applications have relaxed requirements for accuracy, so they can tolerate errors in results and achieve high performance. In approximate computing, multipliers have been widely studied, but squarers (as similar schemes) have not received much attention.
In this paper, an accurate squarer is designed based on a Radix-8 Booth-folding square algorithm to reduce the number of partial products and the depth of the partial product array. Several approximate squarers (R8AS1, R8AS2 and R8AS3) are proposed based on the exact squarer to reduce power and delay. Two approximate partial product generators are also designed to simplify the Radix-8 Booth square encoder in R8AS1 and R8AS2. In addition, approximate compressors with compensation are used in the partial product compression stage to reduce additional area and power consumption in R8AS3. Synthesis results for power, area, and delay at 28nm CMOS technology are presented. Compared with designs in the technical literature with the same accuracy, the proposed 16-bit designs
reduce the PDP by 37%; in general, the PDP is decreased by up to 51%. Finally, the proposed approximate squarers are implemented in a square-law detector as a communication application and achieve an SNR close to 30dB. Also, the three proposed approximate squarers are applied to the k-means clustering algorithm for machine learning to accomplish high performance in classification
Construction of Credit Mechanism in E-commerce SocietySubtitle as needed
No full textAbstract—Today, E-commerce has evolved into an indispensible part in people’s life and work, due to its features of convenience, high-efficiency, etc.As E-commerce becomes popular and develops sharply, its credit crisis emerges increasingly remarkably, including the inadequate regulation, the network complaints, and the rising number of fraud cases. Because of network vulnerabilities and illicit competition in trading market, consumers have substantially reduced their trust in E-commerce. It is apparent that E-commerce credit crisis has turned into one of the main obstacles impacting the development of E-commerce. Key words-E-commerce, credit crisis, construction system, optimization, renovation * Chenyu liu is the first author; Miaoyan Shen is the correspondence author; Bin Huang is the instructor
Crystal twinning of bicontinuous cubic structures
No full textBicontinuous cubic structures in soft matter consist of two intertwining labyrinths separated by a partitioning layer. Combining experiments, numerical modelling and techniques in differential geometry, we investigate twinning defects in bicontinuous cubic structures. We first demonstrate that a twin boundary is most likely to occur at a plane that cuts the partitioning layer almost perpendicularly, so that the perturbation caused by twinning remains minimal. This principle can be used as a criterion to identify potential twin boundaries, as demonstrated through detailed investigations of mesoporous silica crystals characterized by diamond and gyroid surfaces. We then discuss that a twin boundary can result from a stacking fault in the arrangement of inter-lamellar attachments at an early stage of structure formation. It is further shown that enhanced curvature fluctuations near the twin boundary would cost energy because of geometrical frustration, which would be eased by a crystal distortion that is experimentally observed
Collective Entrainment and Confinement Amplify Transport by Schooling Microswimmers
Get PDFMicroswimmers can serve as cargo carriers that move deep inside complex flow networks. When a school collectively entrains the surrounding fluid, their transport capacity can be enhanced. This effect is quantified with good agreement between experiments with self-propelled droplets and a confined Brinkman squirmer model. The volume of liquid entrained can be much larger than the droplet itself, amplifying the effective cargo capacity over an order of magnitude, even for dilute schools. Hence, biological and engineered swimmers can efficiently transport materials into confined environments

Design and analysis for a steel braceless semi-submersible hull for supporting a 5-MW horizontal axis wind turbine
Get PDFThis thesis deals with design and analysis of steel semisubmersible hulls for supporting MW-level horizontal axis wind turbines. The thesis address the following four topics: 1) conceptual design methods, 2) conceptual design of a steel braceless hull for supporting a reference wind turbine (denoted as 5-MW-CSC), 3) development, verification and validation of numerical approaches for analyzing global structural responses of structural components of semi-submersible hulls in wind and waves, and 4) case studies related to numerical simulations and experimental measurements for load and load effects on semi-submersible wind turbines. Simplified design procedure, criteria and design check approaches for conceptual design with respect to safety have been systematically presented and discussed based on publicly accessible publications and the author’s experience and practice in the past six years.
The 5-MW-CSC is developed based on the simplified design procedure, criteria and design check approaches. Numerical analysis shows that the 5-MW-CSC has very good intact stability, well designed natural periods and modes, moderate rigid-body motions in extreme environmental conditions and a reasonable structural design.
The structural design of the 5-MW-CSC is checked by using simplified ULS and FLS design checks. Two time-domain approaches, which can be easily implemented in various state-of-theart computer codes to extend their capabilities to analyze sectional forces and moments in structural components of generic and specific floaters subject to environmental loads from wind and waves, were developed by the author. The developed approaches focus on modeling of inertia and external loads on the floaters and mapping of the loads in finite element model of the floaters. The floaters are considered as an assemblage of several structural components. The conventional hybrid frequency-time domain approach is extended to model the external loads on and inertia loads of each structural component. Limitations of the developed time-domain approaches and future work for solving these limitations are discussed.
The developed approach for generic floaters were verified and validated by comparing with simulated responses given by other reference numerical models and measurements from a 1:30 scaled model test campaign using the ReaTHM® testing approach to overcome the limitations of conventional model test approaches. The verification and validation consist of five comparisons. Objectives and expected results of the five comparisons are illustrated. In general, the comparisons agree with the expectations while possible reasons for the deviations are thoroughly and quantitatively analyzed.
Effect of non-linear wave excitation loads, drag forces, each load component, and steady wind and wave loads induced by changes of the mean wetted body surface on rigid-body motions and sectional bending moments in five specified cross-sections on the hull of the 5-MW-CSC were analyzed by comparing the measurements of the model test campaign and carrying out numerical sensitivity study.
These analyses shed more light on features of the loads and load effect on and critical structural components of the hull of the 5-MWCSC, and critical environmental conditions for the 5-MW-CSC with respect to fatigue damage and extreme load effects. The obtained understanding was used to simplify complexity of numerical models of the 5-MW-CSC to reduce computational cost of the design checks, and is helpful for reducing design conditions required by ULS and FLS design checks and structural optimization.
Experience acquired from design and analysis of the 5-MW-CSC and development of the time-domain approaches will promote development of novel and cost efficient designs of semi-submersible wind turbines; while the 5-MW-CSC and developed approaches can be used as reference to validate other computer codes for analyzing global responses of floating wind turbines
