In three-dimensional (3D) integrated circuit (IC), a large number of dummy through silicon vias (TSV) are required for thermal and thinning concerns. However, limited attention is paid to the fact that these dummy TSVs can be multi-functional and used for timing purposes. In this paper, we propose to use those "timing wasteful" dummy TSVs to replace bit line delay cells. Also, a TSV allocation algorithm is presented to optimize the TSV array layout. Finally, three memory designs are implemented to verify the feasibility and reliability of the proposed technology. It is found that all delay cells in these 3 memories can be replaced by TSV arrays.

A large proportion of industrial systems are represented by LTI transfer functions. the PID controller is one of the most used;the lead-lag controller is a more practical alternative. this paper focused on the design of lead-lag-like controller by optimization of the time-domain objective function. the particle swarm optimization algorithm is selected to finding the optimal solutions. the proposed method force all the particles to search the optimum more exhaustedly. Designers can make a choice in a variety of specifications. If the plant could be modeled as a LTI transfer function, the proposed method will design the controller to be able to approach the required specifications. Computer simulations reveal that the performance can be fully meet or very close to desired. © 2016 IEEE.

In this paper, the solution for the satisfaction of Maximal Boolean Polynomial Equations based on Genetic Algorithm is proposed. the Genetic Algorithm is used to model the problem in this method, and the population of the Genetic Algorithm is taken as the solution space of the equation set and the individual is a feasible solution of the equation set. By applying the binary fitness code to the individual and selecting the appropriate individual fitness evaluation function, the more the number of the individual which make more equations with the value of 0 in the Boolean system is, the higher the corresponding fitness value is. After the selection operation, crossover operation and mutation operation, individuals with higher fitness are retained and inherited to the next generation until the algorithm converges and eventually obtains the approximate optimal solution of the problem. Using matlab to program, the optimal solution obtained in the experimental examples is 182.

In today's data-driven world, economy and research depend on the analysis of empirical datasets to guide decision making. these applications often encompass a rich variety of data types and special purpose processing models. We believe, the database system of the future will integrate flexible processing and storage of a variety of data types in a scalable and integrated end-to-end solution. In this paper, we propose a database system architecture that is designed from the core to support these goals. In the discussion we will especially focus on the multi-domain programming concept of the proposed architecture that exploits domain specific knowledge to guide compiler based optimization.

Analyzing, testing, and optimizing source code are techniques that improve software quality and the performance of features and energy consumption of systems. Source code analysis includes analyzing the source code of an application and checking aspects to detect potential problems based on previous experience. In this paper, we investigate the rules and techniques of analyzing and optimizing Java source code by using PMD and Android lint. An automatic code-analyzing and code refactoring tool is developed with a set of rules based on the Eclipse Refactoring API (plug-in) to getoptimized code that consumes less energy and improves performance for Android applications. the optimized code was tested in real environments with positive results. It reveals that programmer could use these techniques and support tool for developing Android applications with high quality source code and reliable and performance.

Helicopter rotor noise optimization 5

Helicopter rotor noise optimization

5th Asian-Australian Rotorcraft Forum, ARF 2016

作者： Pednekar, Shourav Dhavaleswar Ramaswamy, R. Mohan, Ranjith IIT Madras Chennai India

In this paper, aerodynamic sound generation from an isolated helicopter rotor blade system is investigated with the intention of employing the acoustic prediction mechanism in conjunction with design and optimization schemes. Emphasis is placed on airfoil shape optimization resulting in a helicopter rotor blade system that generates the lowest noise for specified conditions. Ffowcs Williams-Hawkings equation is used to predict aerodynamically generated noise from a helicopter rotor blade system. the design aspect of the work deals with designing a rotor airfoil to reduce the aerodynamic noise produced by helicopter rotor blades. the airfoil shape design methodology requires the integration of three distinct modules - a shape parameterization function, an aeroacoustic solver and a search agent for shape optimization. the geometric shape design module uses the PARSEC parametrization method which characterizes the airfoil geometry as a finite number of parametric control handles. these parameters form inputs to the optimization algorithm, which when coupled with the acoustic prediction code, gives an optimally designed airfoil. the simulated annealing algorithm is used as the search agent. Results of the reduction in the predicted noise levels for three optimization cases are presented. Results are also provided for noise optimization with an aerodynamic constraint. Effects on the acoustic predictions for different blade design parameters such as chord length and tip modifications such as sweep and taper are discussed.

MECHANICS BASED DESIGN OF STRUCTURES AND MACHINES 2016年第1-2期44卷 146-159页

作者： Kuenzer, U. Husty, M. L. Univ Innsbruck Inst Basic Sci Engn Unit Geometry & CAD Technikerstr 13 A-6020 Innsbruck Austria

In this article, an algorithm is presented that transforms a given trajectory of a general 6-R Robot in Cartesian task space (position and orientation) into all possible joint space trajectories. It is shown how all solutions of the inverse kinematics can be used to obtain continuous joint trajectories. Inverse kinematics yields up to 16 different solution paths in joint space and these joint paths are compared using different optimality criteria. To achieve this goal the Cartesian trajectory is discretized and at each instant the inverse kinematics is computed using a fast algorithm developed in Pfurner and Husty et al. In the set of joint angles corresponding to the inverse kinematics solutions coherent paths are determined and interpolated with quintic splines. Different boundary conditions for the construction of the splines are discussed. Using the splines some possibilities for the optimal choice among the paths using different criteria are presented.

Programming in HPC is a tedious work. therefore functional programming languages that generate HPC programs have been proposed. However, they are not widely used by application scientists, because of learning barrier, and lack of demonstrated application performance. We have designed Formura which adopts application-friendly features such as typed rational array indices. Formura users can describe mathematical concepts such as operation over derivative operators using functional programming. Formura allows intuitive expression over array elements while ensuring the program is a stencil computation, so that state-of-the-art stencil optimization techniques such as temporal blocking is always applied to Formura-generated program. We demonstrate the usefulness of Formura by implementing a preliminary below-ground biology simulation. Optimized C-code are generated from 672 bytes of Formura program. the simulation was executed on the full nodes of the K computer, with 1.184 Pflops, 11.62% floating-point-instruction efficiency, and 31.26% memory throughput efficiency.

Some organizations end up reimplementing the same class of business process over and over: an "administrative process", which consists of managing a form through several states and involving various roles in the organization. this results in wasted time that could be dedicated to better understanding the process or dealing with the fine details that are specific to the process. Existing virtual office solutions require specific training and infrastructure andmay result in vendor lock-in. In this paper, we propose using a high-level domain-specific language (AdminDSL) to describe the administrative process and a separate code generator targeting a standard web framework. We have implemented the approach using Xtext, EGL and the Django web framework, and we illustrate it through two case studies: a synthetic examination process which illustrates the architecture of the generated code, and a real-world workplace survey process that identified several future avenues for improvement.
