the purpose of this study is the utilization of furfural residue for heating energy and activated carbon production. to evaluate the energy production of the residue, bulk density, melting point, and heating value were measured. furthermore, moisture, ash, volatile compounds, fixed carbon, lignin, and elements were determined. ash and volatile content average were measured at 15.4% and 68.9%, r...

The high reliability and flexibility of Battery Energy Storage (BES) resources in comparison with other renewable technologies promote the development this technology smart grids. fast response BES to load variations could help power system operators maintain balance generation consumption real-time, improve grid, effectively. In work, a new model is presented that determines aggregated schedul...

The five-dimensional description of generalized Randall-Sundrum cosmology is mapped via holography to a generalization of the Starobinsky model. This provides a holographic dual description of the cosmological brane-bulk energy exchange processes studied previously. Some simple solutions are presented in four dimensions.

The consequences for the brane cosmological evolution of energy exchange between the brane and the bulk are analysed in detail, in the context of a non-factorizable background geometry with vanishing effective cosmological constant on the brane. A rich variety of brane cosmologies is obtained, depending on the precise mechanism of energy transfer, the equation of state of brane-matter and the s...

In this paper we consider the bulk-brane interaction to obtain the equation of state for the holographic energy density in non-flat universe enclosed by the event horizon measured from the sphere of horizon named L. We assumes that the cold dark matter energy density on the brane is conserved, but the holographic dark energy density on the brane is not conserved due to brane-bulk energy exchang...

The consequences for the brane cosmological evolution of energy exchange between the brane and the bulk are analyzed. A rich variety of brane cosmologies is obtained, depending on the precise mechanism of energy transfer, the equation of state of brane-matter and the spatial topology. An accelerating era is generically a feature of the solutions. Prepared for 36th International Symposium Ahrens...

We demonstrate that energy can be transferred very rapidly from the bulk to the brane through parametric resonance. In a simple realization, we consider a massless bulk field that interacts only with fields localized on the brane. We assume an initial field configuration that has the form of a wave-packet moving towards the brane. During the reflection of the wave-packet by the brane the locali...

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 ...

The topic of the presentation is about a work package of our on-going Finnish national research program SGEM (Smart Grids and Energy Markets), where smart grid concept – a low-voltage direct current (LVDC) distribution network is researched. The research is mainly carried out in Lappeenranta University of Technology (LUT). In the LVDC concept, smart grid functionalities, such as smart metering,...
