macro programming a Spatial Computer with Bayesian Networks

ACM TRANSACTIONS ON AUTONOMOUS AND ADAPTIVE SYSTEMS 2011年第2期6卷 16-16页

作者： Mamei, Marco Univ Modena & Reggio Emilia DISMI Reggio Emilia Italy

macro programming a spatial computer is the ability to specify application tasks at a global level while relying on compiler-like software to translate the global tasks into the individual component activities. Bayesian networks can be regarded as a powerful tool for macro programming a spatial computer, such as a dense sensor network, in a variety of data analysis applications. In this article we present our architecture to program a spatial computer by means of a distributed Bayesian network and present some applications we developed over a sensor network testing both inference and anomaly-detection analysis.

CNC machines are required to enhance the quality of a product at a reasonable cost. Profiles like turbine blades, dies, car bodies, aerofoil models and vanes are usually to be machined on a CNC machine. Preparatory codes on CNC machines provide automation but restricted with a capacity to machine linear and circular interpolators (G01 and G02 or G03). Hence, due to the non-availability of appropriate preparatory function, CNC machining of these curved shape components causes difficulty. The CAD/CAM systems divide the profile into the numbers of small linear segments. The transmission of the linear segments is subjected to errors between CAD/CAM and CNC systems. It results in lost data and noise. The discontinuity of the curved toolpath deteriorates the surface quality and shape accuracy due to linear segments. To reduce the deviation of the toolpath, the numbers of linear segments are to be increased. Each linear segment to be machine is adding a single block in the part program. It will lengthen the part program and add to the program memory size at the cost of the surface quality. To achieve better shape accuracy, parametric interpolation (i.e. macro programming) is required. In the present work, NURBS, as well as Hermite interpolators, is attempted to machine regular axis-symmetrical profile (i.e. circle) using explicit functions. The curved profiles machined by macro and conventional programming methods are examined to measure surface quality using surface roughness tester (i.e. Mitutoyo SJ-210®), while toolpath deviation is examined with the actual profile plotted with CAD software (i.e. AutoCAD®). © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

programming IoT systems: A focused conceptual framework and survey of approaches

INTERNET OF THINGS 2025年 31卷

Any software engineer of Internet of Things (IoT) systems deals with three macro issues: how to perceive the properties of interest through sensors (sensing facet), how to process such information to decide what to do to achieve the system goals (processing facet), and how to enact such decisions by affecting the IoT system itself and its deployment environment accordingly (actuation facet). For each, one can either develop ad-hoc solutions from scratch, with mainstream programming languages, or build on top of existing IoT-specific software libraries, frameworks, and platforms. Here, we survey the broad state of the art of "IoT programming", with a focus on clarifying which and how programming paradigms and platforms deal with four key features demanded by modern IoT systems: scale-independence, situatedness, adaptiveness, and opportunistic deployment, along the aforementioned three facets. We motivate such needs by describing compelling contemporary and near future scenarios. Then, we propose a reference conceptual framework of programming IoT systems with the goal of (i) uncovering which research areas are mostly active in IoT programming, and (ii) placing the state of the art at the intersection between the appropriate features and facets, to both (iii) clarify which approaches are most suited for different kinds of tasks, and (iv) emphasising open challenges. This conceptual framework is a novel contribution in the landscape of IoT programming surveys, and is intended to be a practical aid for researchers and practitioners that are deciding which computational tools (e.g. languages and platforms) to adopt while building their own IoT systems.

Wireless Sensor Networks (WSNs) are highly coexisting, dynamic and application specific, as well as having resource constrained in nature, thus programming the sensor nodes is difficult when compared to traditional computer systems. It is most difficult task to build reliable and practical programming solutions or systems for distributed and resource-constrained wireless sensor devices. The objective of this research contribution is to present a comparative study in terms of programming approaches, its potentials and pitfalls.

Elliptical curve machining with variable feed rate for shape accuracy

引用

ROBOTICS AND COMPUTER-INTEGRATED MANUFACTURING 2018年 50卷 37-49页

Generally, tool path deviates from curved geometry as tool path interpolates linearly between two successive cutter location points. Deviation of the tool is directly proportionate with a curvature of the geometry. Any approach improving the shape accuracy is laborious and time consuming. The main objective of the present study is to reduce the problem of shape accuracy. This required generating a curved profile from a Set of control points such that the tool moves smooth from one point to another point. Various methods are studied for the interpolation of elliptical curve by deciding a number of control points as per curvature. The control points can be decided by two ways: a) Minimizing difference between arc length and chord length between two cutter location points. b) Minimizing chordal height between two successive cutter location points on the curve. The novel approach, finding shape error by the intersection of lines, is suggested to determine the number of control points to improve shape accuracy. Variable feed rate is proposed as per the number of control points considering the curvature effect of the tool path. The shape accuracy of elliptical curve of the present approach is compared with the earlier studies and reported. (C) 2017 Elsevier Ltd. All rights reserved.

Forecasting and Time series techniques are frequently used and play extremely important roles in managerial activities and decision-making processes. Holt-Winters (HW) which is one of the most popular forecasting methods is utilized in cases where data show seasonality and/or trend. The method involves the selection of several parameters for optimum prediction results. Heuristics are usually utilized for optimum parameter selection and it appears to be an open field for improvement. In this study "Spreadsheet modeling" of HW method is improved by minimizing the mean squared error (i.e. prediction error). Since the forecast error is nonlinear function;Holt-Winters parameter optimization in this study is achieved by "Excel Nonlinear Solver" and "Differential Evolution Search" techniques. To increase the usability of the spreadsheet modeling advance macro programming techniques are incorporated with the developed models in Microsoft Excel.

The manufacturing method of two spatial-orthogonal rotary axis linkage is usually used to cut hourglass worm. However, the traditional processing method of roughing tooth groove depends on the special machine, specific tool, and its processing efficiency is lower. To avoid these defects, a processing method of the rough cutting hourglass worm on general NC lathe without C-axis functions was presented in the paper. Based on the forming principle of the hourglass worm and the traditional processing steps, the machining principle of the new approach was elaborated. Key techniques such as the shape of the blade, the contours of tooth groove, tool path loop and the variable lead of worm, etc. were discussed. macro-program of the new method was programmed based on Fanuc of mate-tc CNC system, and tooth groove of the hourglass worm were trial manufactured on general NC lathe. Addendum axial pitch and a normal tooth thickness of the trial model were measured. It is noted that measurement results can satisfy the technological requirement. In conclusion, the new processing method of roughing hourglass worm is feasible and efficient.

macroprogramming: Concepts, State of the Art, and Opportunities of macroscopic Behaviour Modelling

ACM COMPUTING SURVEYS 2023年第13S期55卷 275-275页

作者： Casadei, Roberto Univ Bologna Alma Mater Studiorum Via dellUniv 50 Cesena Italy

macroprogramming refers to the theory and practice of expressing the macro(scopic) behaviour of a collective system using a single program. macroprogramming approaches are motivated by the need of effectively capturing global/system-level aspects and the collective behaviour of multiple computational components, while abstracting over low-level details. Previously, this programming style had been primarily adopted to describe the data-processing logic in sensor networks;recently, research forums on spatial computing, collective systems, and the Internet of Things have provided renewed interest in macro approaches. However, related contributions are still fragmented and lack conceptual consistency. Therefore, to foster principled research, an integrated view of the field is provided, together with opportunities and challenges.
