In this paper, a novel resource management approach is presented for publish-subscribe middleware for sensor/actuator networks. The resource management was designed with the possibility to add non-functional requirements at runtime to subscription messages. This approach allows utilizing service level agreements that can then be employed in order to guarantee a certain quality of service or to ...

To optimize belt conveyor system (BCS) performance, a reasonable assessment of system reliability is desired and the decisions of how often to perform maintenance and the optimal occasion to replace a component are required. Intelligent belt conveyor monitoring (BCM) may automate the maintenance process. To realize such an intelligent system most of parameters of BCS have to be monitored. Too m...

We present a toolbox for cold atom manipulation with time-dependent magnetic fields generated by an atom chip. Wire layouts, detailed experimental procedures and results are presented for the following experiments: Use of a magnetic conveyor belt for positioning of cold atoms and Bose-Einstein condensates with a resolution of two nanometers; splitting of thermal clouds and BECs in adjustable ma...

The ability to obtain 3D information is vital for many applications in construction, manufacturing, and vehicle automation and autonomy. TOF (Time-of-Flight) sensors, which provide depth information at each pixel in addition to intensity, are becoming more widely available and more affordable. This paper examines the applicability of TOF sensors to several real world problems that can be releva...

In this paper new methods for stress depending maintenance strategies based on a signaland observer based system for large scale belt conveyor systems are presented. This new approach will provide much more information about the system conditions and mechanical abrasion to optimize the current maintenance schemes. Belt conveyors operate under the presence of many disturbances and strong paramet...

An industrial case study for scheduling the personalisation of smart cards is presented and analysed. Smart cards are personalised in several machines that are served by an underlying conveyor belt connecting these. As there are usually a very high number of smart cards to be personalised, the focus is on cyclic schedules and the goal is to obtain a plan with high throughput. By characterizing ...

Introduction: Since the first Antarctic meteorite concentrations were discovered more than 25 years ago, many theories regarding the role of iceflow in the production of meteorite concentrations have been put forward , and most agree on the basic principles [1-3]. These models suggest that as the East Antarctic icesheet flows toward the margins of the continent, meteorites randomly located with...

The efficiency of manure separation by a conveyor belt under a partially slatted floor for fattening pigs was determined for two types of belts, a flat belt with an incline of up to 6 degrees transversely and a concave belt with an incline of up to 1 degrees longitudinally. A 31.20% and 23.75% dry matter content of the solid fraction was obtained for the flat and concave belt, respectively. The...

Breaks in the so-called “continuous” (unspliced) belt sections, and not spliced areas, are infrequent but do happen practice. This article presents some aspects, which may account for such breaks conveyor belts. It indicates “sensitive points” design, especially transition section of identifying actual strength belt. The presented results include influence width a specimen on identified tensile...

Warm conveyor belts (WCBs) are the main ascending air masses within extratropical cyclones. They often exhibit strong condensation and precipitation, associated with ascent on large scales or embedded convection. Most of the air outflows into the upper troposphere as part of a ridge. Such ridges are an integral part of Rossby waves propagating along the tropopause and are identified with a nega...
