Locks are important safety devices in our daily lives. The purpose of this study is to design new mechanisms of multipoint mortise locks based on a systematic approach. Firstly, the classification and advantages of mechanical locks are introduced, and the definitions and the development of mortise locks are described. Then, the multipoint mortise locks are decomposed into four sub-parts by the different functions, including the latch bolt lock, the dead bolt lock, the dead-latch bolt lock, and the connecting mechanism. The four sub-parts are further analyzed to conclude their structural characteristics as well as design requirements and constraints. Based on Yan’s creative mechanism design methodology, the concepts and the atlas of designs are synthesized systematically. One feasible mechanism is further chosen for detail design. Finally, a computer program for simulation is developed and prototypes are built for verifying the design results. The results of this study provide a valuable reference for designing multipoint mortise locks and for the analysis of mechanism characteristics of mortise locks.

Currently, agricultural science and practice has a large amount of experimental data that need to be taken into account in the development of new technological processes and working bodies. Therefore, there is a need to design technical processes in order to identify their effectiveness. In this regard, the use of methods of synthesis of technological processes based on the characteristics of tillage, seeding and production system of the economy, in which it is necessary to implement the projected process. In the General statement of the problem, the design of technological processes is one of the complex problems with the following characteristic feature: lack of knowledge about the methods of designing technological processes, suitable for system - structural modeling and algorithmization of design processes. To overcome this incompleteness, a systematic approach is needed. The system approach proceeds from the fact that the specificity of complex objects and processes is not limited to the features of its constituent parts and elements, but lies in the nature of relationships and relationships between them. In this paper, the design methodology is based on the formulated fundamental assumptions and principles of the whole system of more specific statements, revealing the structure and content of design operations, the synthesis of the choice of solutions. The principles of technological compatibility and emergence suitable for system-structural analysis of complex technical means and technological processes, consisting of statements having a hierarchical structure, where the degree of detail of the goals from level to level increases, and the approval of the last level determines the direction of the search for the optimal solution to the problem.

Bias Selection

Evaluations of the toxic potential of drugs and chemicals often involve statistical comparisons of effects between treatment groups. Such comparisons are valid and permit elucidation of spontaneous versus treatment effects only if the sampling population is obtained without selection bias. Selection bias is routinely minimized or controlled by random sampling or unbiased allocation of animals to treatment groups. A systematic approach using a computerized procedure is described that fulfills these requirements in a simple and efficient fashion.

Feedback Interventions

Purpose This paper aims to extend the argument of DeNisi & Smith Sockbeson, who called to bridge the gap between feedback-seeking and feedback-giving research. The paper pushes their argument further by suggesting that future feedback research should systematically adopt a dyadic and dynamic approach to enhance the understanding of feedback episodes. Design/methodology/approach This paper reviews previous empirical work in the feedback domain and develops conceptual arguments for linking feedback-seeking and feedback intervention research. Findings Drawing upon previous work, the authors conclude that the current depiction of feedback processes in the literature might have been overly static and one-sided. Furthermore, it is argued that feedback research might have not kept up to date with recent conceptual and methodological developments in dyadic organizational behavior research. Research limitations/implications This paper builds on the argument of DeNisi & Smith Sockbeson, in turn contributing to a more complete picture of how feedback processes unfold in organizations. While this paper profiles a few studies that have begun to bridge the disconnect between feedback-seeking and feedback-giving research, one of its limitations is that it does not adopt a systematic approach in reviewing all potential methodologies. Originality/value This paper provides a first step toward studying feedback episodes as dyadic and dynamic processes. In doing so it helps solving one of the long-standing puzzles in management research namely why feedback interventions are sometimes detrimental to performance.

The Impact

Social networking tools have become an integral part of our daily lives. Recently, a new type of Social Networking Sites (SNSs) namely Academic Social Networking sites (ASNSs) has attracted global users. There is perceived usefulness on the impact of ASNSs on patterns of academic research activities. However, it remains unclear why some researchers do not use ASNSs at all. The purpose of this paper is therefore to explore the ASNSs usage among Malaysian academic researchers and to investigate benefits, specific purpose, drivers and barriers of using ASNSs. A total of 210 completed cases were collected through paper-based and online-based questionnaire. In order to show the outcome of the research, descriptive interpretation of data is performed. The overall findings of this research indicate that there is low rate of ASNSs usage among researchers. In addition, the results show that colleagues, attitude toward technology and communication benefits are the drivers to use ASNSs and trust, privacy and security are the common barriers regarding to use ASNSs.

Integrated Design Methodology

Global markets demand quick product develop-ment that is simultaneously cost-effective and meets stakeholder needs. Many tools and design methodolo-gies have been developed that address individual as-pects of the design problem, such as Axiomatic De-sign, Design for Manufacture, Life Cycle Design, etc. However, competitive viability can be put at risk when a product fails to achieve all customer, business, manufacturing, and regulatory requirements. To de-liver all design requirements, an efficient integrated design methodology is required. This paper proposes a design approach which integrates previously devel-oped design tools to economically achieve essential design objectives, within a framework that facilitates a rapid design process.

This paper describes the current pressure protection program at Savannah River Site (SRS), a Department of Energy chemical processing and nuclear material handling facility in Aiken, South Carolina. It gives a brief description of the design requirements based on ASME, API, CGA, and ASHRAE Codes. Equipment and systems requiring pressure protection at SRS are primarily pressure vessels, steam stations, process chemical systems, refrigerant and cryogenic systems and other air or gas systems. It is understood that any pressure protection program is built on five fundamental areas of responsibility: procurement, verification, registration, inspection, and repair. This paper focuses on the existing process of facility pressure protection evaluation for code compliance followed by identification of failure scenarios and system design requirements, valve selection and sizing, and verification record generation. Improvements to this process are recognized and discussed. They include the development of a computer program to perform pressure protection evaluation and generate verification records. The software would process all applicable pressure protection calculations using improved methodologies. All relevant data required would be accessible within the program. Pressure safety relief device attributes and system parameters would be displayed. The computer program would enhance design consistency, improve quality and plant safety, and make the pressure protection verification process more efficient and cost effective.
