Calibration of precipitation estimation algorithm with particular emphasis on the Pomeranian region using high performance computing
PublicationFast and accurate precipitation estimation is an important element of remote atmosphere monitoring, as it allows, for example, to correct short-term weather forecasts and the prediction of several types of meteorological threats. The paper presents methodology for calibrating precipitation estimation algorithm based on MSG SEVIRI sensor data, and Optimal Cloud Analysis product available via EumetCast transmission. Calibration is...

ENHANCED MASTER CYCLE - SIGNIFICANT IMPROVEMENT OF STEAM RANKINE CYCLE
PublicationThe present paper focuses on an enhancement of the Master Cycle. In the first part, the paper presents a classical Master Cycle which is a modification of the double reheat Rankine cycle. This modification allows to slightly increase efficiency, resolves problems caused by superheated steam on bleeds and decreases mass flow rate of steam directed to reheat. These improvements include the implementation of a tuning turbine from...

Impact evaluation of a cycling promotion campaign using daily bicycle counters data: The case of Cycling May in Poland
PublicationThe promotion of active and sustainable transport modes as an alternative to motorised individual transport has become a key policy priority in Europe, to reduce air pollution, road congestion, noise, traffic injuries, and the adverse health outcomes of sedentary lifestyles. Policymakers are implementing a wide range of measures to encourage this shift in attitudes and behaviours. These interventions are most valuable when targeting...

Efficient parallel implementation of crowd simulation using a hybrid CPU+GPU high performance computing system
PublicationIn the paper we present a modern efficient parallel OpenMP+CUDA implementation of crowd simulation for hybrid CPU+GPU systems and demonstrate its higher performance over CPU-only and GPU-only implementations for several problem sizes including 10 000, 50 000, 100 000, 500 000 and 1 000 000 agents. We show how performance varies for various tile sizes and what CPU–GPU load balancing settings shall be preferred for various domain...

Multi-objective Tabu-based Differential Evolution for Teleportation of Smart Virtual Machines in Private Computing Clouds
PublicationWe propose a multi-objective approach for using differential evolution algorithm with tabu search algorithm as an additional mutation for live migration (teleportation) of virtual machines. This issue is crucial in private computing clouds. Teleportation of virtual machines is supposed to be planned to determine Pareto-optimal solutions for several criteria such as workload of the bottleneck host, communication capacity of the...

Organic Rankine as bottoming cycle to a combined Brayton and Clausius-Rankine cycle
PublicationThis paper presents an enhanced approach, as it will be considered here that the ORC installation could be extra-heated with the bleed steam, a concept presented by the authors. In such way the efficiency of the bottoming cycle can be increased and an amount of electricity generated increases. A thermodynamic analysis and a comparative study of the cycle efficiency for a simplified steam cycle cooperating with ORC cycle will be...

The Life Cycle Assessment and Life Cycle Cost in public works contracts
PublicationAn important goal, implemented by EU countries under the Europe 2020 strategy, is sustainable development, which includes supporting economy that effectively uses natural and environmentally friendly resources. Solutions in this area are also promoted in tender proceedings in the area of public procurement. The LCA (Life Cycle Assessment) and LCC (Life Cycle Cost) analysis are indicated as the basis for decision-making by awarding...

A simple access to o-acyl bicyne
PublicationW publikacji przedstawiono prostą metodę otrzymywania o-acylowych pochodnych bicyny. Substratem do syntezy była n,n-bis(2-hydroksyetylo)glicyna - bicyna. Bicynę najpierw przeprowadzano w ester benzylowy w reakcji z alkoholem benzylowym i kwasem p-toluenosulfonowym w temp. 75 st. C. Tak otrzymany związek, acylowano kwasami organicznymi w obecności DCC ( dicyklokeksylokarbodiimid)i DMAP (dimetyloaminopirydyna), otrzymując o-acylowe...

KernelHive: a new workflow-based framework for multilevel high performance computing using clusters and workstations with CPUs and GPUs
PublicationThe paper presents a new open-source framework called KernelHive for multilevel parallelization of computations among various clusters, cluster nodes, and finally, among both CPUs and GPUs for a particular application. An application is modeled as an acyclic directed graph with a possibility to run nodes in parallel and automatic expansion of nodes (called node unrolling) depending on the number of computation units available....

DEPO: A dynamic energy‐performance optimizer tool for automatic power capping for energy efficient high‐performance computing
PublicationIn the article we propose an automatic power capping software tool DEPO that allows one to perform runtime optimization of performance and energy related metrics. For an assumed application model with an initialization phase followed by a running phase with uniform compute and memory intensity, the tool performs automatic tuning engaging one of the two exploration algorithms—linear search (LS) and golden section search (GSS), finds...

Dynamic GPU power capping with online performance tracing for energy efficient GPU computing using DEPO tool
PublicationGPU accelerators have become essential to the recent advance in computational power of high- performance computing (HPC) systems. Current HPC systems’ reaching an approximately 20–30 mega-watt power demand has resulted in increasing CO2 emissions, energy costs and necessitate increasingly complex cooling systems. This is a very real challenge. To address this, new mechanisms of software power control could be employed. In this...

Application of Organic Rankine Cycle as bottoming cycle to conventional heat and power plant
PublicationW pracy rozważono możliwość zastosowania układu ORC w skojarzeniu z ciepłownią lub elektrociepłownią celem podniesienia stopnia wykorzystania jednostki CHP podczas eksploatacji w skali roku. Połączenie układu ORC z zawodową jednostką CHP może wpłynąć na wzrost rocznej produkcji energii elektrycznej i jednoczsne zmniejszenie fluktuacji podczas pracy bloku energetycznego. Z jednej strony następuje konwersja energii cieplnej na elektryczną...
