The success of high-level programming models in Wireless Sensor Networks (WSNs) is heavily dependent on factors such as ease of programming, code well-structuring, degree of code reusability, and required software development effort. Component-based programming has been recognized as an effective approach to meet such requirements. Most of componentization efforts in WSNs were ineffective due t...

حسگرهای نیرو/گشتاور چند‌مولفه‌ای کرنش‌سنج‌دار، برای اندازه‌گیری همزمان نیروها و گشتاورهای استاتیکی و دینامیکی شامل سه مولفه‌ی نیرو و سه مولفه‌ی گشتاور در دستگاه مختصات دکارتی یک سیستم استفاده می‌شوند. در این تحقیق، یک حسگر نیرو/گشتاور شش‌مولفه‌ای نوع ستونی، با سطح مقطع دایروی توخالی معرفی شده است. به منظور جداسازی الکتریکی مولفه‌های بار اعمالی بر آن و بر پایه‌ی مبانی نظری، الگوهایی خاصی برای نص...

The role of small electronic devices has been growing over the past years. Many types of devices which allow for interaction with the environment can now be found in the market and there is large set of solutions for integration of mobile devices with enterprise systems. However, most such solutions focus only on providing base services for other SOA system elements. The paper presents an exten...

Redundant sensors have been widely used in safety critical facilities such as nuclear power and chemical plants. As these industries strive to move towards condition-based sensor calibration practices, on-line calibration verification algorithms must be developed. Independent component analysis (ICA) can be applied for redundant sensor validation. Independent component analysis is a statistical...

This paper describes the methodology adopted for developing a simulator for airborne altimetric LiDAR. The goal is to model LiDAR sensor functioning so LiDAR data can be generated for a user specified terrain with given parameters of the sensor and aerial platform. The simulator is conceived having three components: 1) Terrain component, 2) Sensor component and 3) Platform component. Terrain co...

This paper describes a method of modeling sensor detectabilty and its implementation in the VANTAGE geometric/sensor modeler. Each sensor consists of one or more light sources and TV cameras, which illuminate and observe, respectively, various portions of faces of an object Sensor detectability, which specifies where the sensor can "see" (detect), can be described by a result of AND/OR operatio...

"Green analytical chemistry" (GAC) succeeded to become an eco-friendly environmental crucial area in the field of analytical chemistry targeting at the chemical processes' and products' optimization regarding to material consumption, generation of waste and intrinsic safety, toxicity and environmental burdens. For an expressive comparison, an electro-analytical in-line potentiometric selective ...
