UNI-SPEC:An Instruction Set Description Language

Microprocessor development emphasizes hardware and software co design. Hw/Sw co design is a modern technique aimed at shortening the time to market in designing the real time and embedded systems. Key feature of this approach is simultaneous development of the program tools and the target processor to match software application. An effective co design flow must therefore support automatic software toolkits generation, without loss of optimizing efficiency. This has resulted in a paradigm shift towards a language based design methodology for microprocessor optimization and exploration. This paper proposes a formal grammar, UNI SPEC, which supports the automatic generation of assemblers, to describe the translation rules from assembly to binary. Based on UNI SPEC, it implements two typical applications, i.e., automatically generating the assembler and the test suites.

Employer Branding Management As A Strategic and Organizational Control Tool

The issue of employer branding has always had an intrinsic interdisciplinary content, since it builds a bridge for cross-fertilization between different disciplines （strategic marketing, strategic management, and human resources management）. This paper presents employer branding as an approach based on effective strategic organizational resources and a precise employer branding management process. In this paper, the target is to define a possible frame in order to interpret employer branding techniques as control and regulation mechanisms. Control in organizations has long been a topic of interest for researchers and practitioners, alike who generally recognize that control mechanisms are needed to ensure that organizations may achieve their goals. It has been carried out a field work on the Italian Aeronautical Meta district, that generates annual revenues equal to EUR 8.7 billion and employees 36,300 people, of whom approximately 10% are employed in the space sector. Through this field work, the intention aim is to understand if and how employer branding may create, enforce, and set up internal and shared meaning and values. In particular, stemming from the empirical research＇s evidences, this paper tries to conceptualize employer branding as a factor to persuade and influence the way that organizational actors enact in a socially constructed context. In this effort, the aim is to understand how managers may affect meanings, values goals, and opinions through an effective action on employer branding that can play a crucial role in affecting sense-making processes, meanings, interpretations of the symbolic environment. The paper therefore opens up to new horizons, since it embraces a new application for employer branding, considering it as a modern control system and proposing an innovative approach in managerial control, founded on organizational identity as a key concept in an organizational citizenship＇s perspective

Research on new type of fast-opening mechanism in steam turbine regulating system and optimization of operation tactic

With the analysis on regulating system in 200 MW steam turbine, the necessity of appending the fast-opening function to the original system is set forth and a new type of fast-opening mechanism is devised. The mathematical model of system is built up. With the use of AMESIM software, the displacement curve of the piston, the force curve of the cartridge valve spool, the pressure curve and the flux curve in the regulation process are obtained based on simulation. The performances of three fast-opening systems composed of cartridge valves with different diameters are compared. Based on the analysis on factors that affect the execution time of fast-opening, the dead zone of the fast-opening system is put forward. To overcome the defect, dif- ferent operation modes are adopted for different zones. The result shows that with the increase of the valve diameter, the regulating time in the dead zone significantly exceeds the fast-opening time in the whole journey. Accordingly, the optimization operation tactic in the dead zone and the qualification conditions are brought forward. The fast-opening system composed of 32 mm cartridge valves is taken as an example with use of the tactic. The simulation result shows that the maximum regulating time is shortened by 509 ms.

A simple anti-windup method for the Modified Smith Predictor

For the first-order integrating processes with long delay, a Modified Smith Predictor (MSP) was analyzed when the control signal saturated. If the MSP controller has no anti-windup scheme, the saturation effectively chops off the control input resulting in performance deterioration. Thus, a simple and effective anti-windup scheme, without an additional parameter, is designed for the MSP. Simulation results illustrate that the proposed method may achieve good performance under the nominal and model uncertainty cases.

Coordinated node scheduling for energy-conserving in large wireless sensor networks

Aiming at developing a node scheduling protocol for sensor networks with fewer active nodes,we propose a coordinated node scheduling protocol based on the presentation of a solution and its optimization to determine whether a node is redundant.The proposed protocol can reduce the number of working nodes by turning off as many redundant nodes as possible without degrading the coverage and connectivity.The simulation result shows that our protocol outperforms the peer with respect to the working node number and dynamic coverage percentage.

Appraisal of Common Dispute Problems on Public Works Projects in Thailand

The objectives of this research were to identify and appraising the common dispute problems in domestic and international funded public works projects. The interview and questionnaire method were used in this research. Randomly distributed questionnaire technique was applied to select samples of 390 various construction practitioners consisting of owners, consultants and main contractors to evaluate the severity of the 43 identified dispute factors. This survey found that contract and specification dispute problem was the highest concern among four main dispute problems for construction practitioners. The insufficient working drawing details factor was ranked as the highest overall severity index. The results of the survey also indicated that both domestic and international funded public projects faced moderately severe dispute level among construction team.

Research on the impact of computer technology on art and design

With the rapid development of digital technology in the new century, modem technology used to provide aid for teaching is widely used. The pattern of education had been great changed in due to input digital technology .There are many tremendous changes such as the information collected and stored, the teaching process and performance, all aspects of the learner receives ways and means, especially the traditional art education be affected at the most significant way. In the traditional art teaching process, educators and learners mainly in the unarmed way of painting and design which tend to form on the art of teaching content recapitulate and mechanical reproduction of art materials for teaching situation. The art of teaching behaviors had become no creativity and creative fun. Modem art education needs innovation; needs to reflect the flavor of the era of technology. Therefore, the new model for art teaching with the perfect combination of the help of modem digital computer technology is becoming the most urgent needs.

Experimental Study of Airflow-Mixture in HVAC Unit by Using PIV

In this paper, experimental results are reported about, especially, effect of turbulence in airflow-mixture in HVAC （heating, ventilating, air-conditioning） unit. A flow channel in this study has same characters as actual HVAC unit, such as bent rectangular duct, a heater unit and a flow control door. The experiment was carried out to obtain verification data for analysis by using PIV （particle image velocimetry） system. Moreover, temperature map in the channel was also obtained by using thermocouples. Reynolds number is set to 12800. As a result of this study, representative velocity distributions and Reynolds stress distributions were obtained. It was found that stress value is quite high （maximum 1.4） by preliminary turbulence and mixture in the duct. In addition, it was also found that temperature diffusion is promoted by mixing around door.

Shaping super-Gaussian beam through digital micro-mirror device

We have set up a novel system for shaping the Gaussian laser beams into super-Gaussian beams.The digital micro-mirror device(DMD)is able to modulate the laser light spatially through binary-amplitude modulation mechanism.With DMD,the irradiance of the laser beam can be redistributed flexibly and various beams with different intensity distribution can be produced.A super-Gaussian beam has been successfully shaped from the Gaussian beam with the use of DMD.This technique will be widely applied in lithography,quantum emulation and holographic optical tweezers which require precise control of beam profile.
