The Grid Collector is a system that facilitates the effective analysis and spontaneous exploration of scientific data. It combines an efficient indexing technology with a Grid file management technology to speed up common analysis jobs on high-energy physics data and to enable some previously impractical analysis jobs. To analyze a set of high-energy collision events, one typically specifies th...

Accurate road speed predictions can help drivers in smart route planning. Although the issue has been studied previously, most existing work focus on arterial roads only, where sensors are configured closely for collecting complete real-time data. For collector roads where sensors sparsely cover, however, speed predictions are often ignored. With GPS-equipped floating car signals being availabl...

Abstract: In this paper we have shown a system based on Bluetooth and ZigBee for hospital environment applications. This system provides an easy way to monitor the patient’s health condition.We have used advanced technical methods to design the system like ZigBee, Bluetooth and ARM9. ARM9 processor requires significantly less transistors than other micro controllers. This reduces the cost, heat...

We study an incorporation of generations into a modern reference counting collector. We start with the two on-the-fly collectors suggested by Levanoni and Petrank: a reference counting collector and a tracing (mark and sweep) collector. We then propose three designs for combining them so that the reference counting collector collects the young generation or the old generation or both. Our desig...

The effects of both abiotic factors and biotic interactions among guilds (i.e., inter-guild effects) have been suggested to be important for understanding spatial variation in species diversity; however, compared to the abiotic effects, the processes by which the inter-guild effects are mediated have been little described. Hence, we investigated stream invertebrate assemblages on Hokkaido Islan...

The use of mobile sensors is of great relevance to monitor critical areas where sensors cannot be deployed manually. The presence of data collector sinks causes increased energy depletion in their proximity, due to the higher relay load under multi-hop communication schemes (sink-hole phenomenon). We propose a new approach towards the solution of this problem by means of an autonomous deploymen...

This study compares environmental and economic impacts of using nanofluids to enhance solar collector efficiency as compared to conventional solar collectors for domestic hotwater systems. Results show that for the current cost of nanoparticles the nanofluid based solar collector has a slightly longer payback period but at the end of its useful life has the same economic savings as a convention...

Abstract: It has been observed that there is sustained bioelectricity in standing trees, which is a potential energy for wireless sensor networks. Manual measurement has been the main approach to obtain data to analyze the mechanism, which is inconvenient and possibly leads to measurement errors. In order to obtain accurate and real-time data, and to avoid human errors, an automatic data collec...

This paper presents the verification of a generational copying garbage collector for the CakeML runtime system. The proof is split into an algorithm proof and an implementation proof. The algorithm proof follows the structure of the informal intuition for the generational collector’s correctness, namely, a partial collection cycle in a generational collector is the same as running a full collec...

Functionalized magnetic particles are used in micrototal analysis systems since they act as magnetically steered mobile substrates in microfluidic channels, and can be collected for bioanalytical processing. Here, we examine the motion of magnetic microbeads in a microfluidic flow under the influence of a nonuniform external magnetic field and characterize their collection in terms of the magne...
