This paper considers how power-based distribution tariffs encourage electricity end-users to invest in energy storages to reduce their peak loads. The study uses actual automatic meter reading (AMR) data from 30 000 customers the annual electricity consumption of which is less than 50 MWh. The customers locate in the area of a Finnish distribution system operator (DSO) operating in an urban env...

Most livestock and poultry odors are generated by the anaerobic decomposition of livestock wastes such as manure (feces and urine), spilled feed, bedding materials, and wash water. Increased organic loading rates due to expanding animal numbers, slug loading, concentrated waste streams, and/or inadequate amounts of dilution water increase the potential for odor emissions from waste management s...

In the past few years, the data warehouse (DW) has regained experts’ interest due to the paradigm shift from data storages to data analysis. During the development of DWs data passes through a number of transformations and are staged in multiple storages which might lead to data corruption and/or manipulation. Hence, testing DWs is a vital stage in the DW development life cycle. In this paper, ...

The seasonal thermal energy storage technology for domestic heating applications is not enjoying the same increasing market penetration as the smaller diurnal thermal energy storage technology. Although high efficiencies are to expect with seasonal thermal energy storages, high up-front costs are likely to constitute an efficient market barrier, impeding the growth of this technology. This pape...

This study shows results of the experimental investigation of regularly structured Composite Latent Heat Storages. Common solid-liquid Phase Change Materials used as latent heat storages have a low thermal conductivity, which leads to high temperature differences inside large PCM volumes. This drawback is compensated by the combination with specially designed frame-structures made of aluminum t...

The automated material handling system (AMHS) is a highly automated transport solution of actual 300mm semiconductor waferfabs. The big logistic challenge in such a running system is the just-in-time delivery of lots (carriers). Therefore, beside tracks and vehicles, there are different storages (stocker) and buffers (under track storages and load ports) integrated in such a transport system. T...

As future HPC systems become larger, the failure rates and the cost of checkpointing to the global file system are expected to increase. To solve this problem, this paper proposes a hierarchical incremental CPR mechanism that utilizes a hierarchical storage system of local storages and global storages. Then, to adjust the parameters of the proposed mechanism, a runtime autotuning technique is p...

The garbage collection is a safe and efficient method for managing the heap. However it is not efficient for temporary storages that are allocated often and deallocated quickly. Reusing temporary storages without collecting garbages can be a remedy for such inefficiency. We present an effect system for checking whether every explicit memory reuse is safe. We abstract the heap by using symbolic ...
