The control of generating resources to follow the unscheduled load changes is considered to be an essential process in the power system in order to maintain the frequency of power supply. This load frequency control (LFC) problem has been given more importance in the recent smart grid environment because of the impact from high penetration of distributed energy resources (DER) installed at the ...

Many available systems-on-chip embedded processors can be specialised for a given application-domain by adding ad-hoc functional units. These functional units can be used to map clusters of elementary arithmetic or logic operations (sections of the dataflow graph); more complex hardware addons could attack the control flow (e.g., map loops onto sequential functional units). For automatic proces...

We propose that microbial diversity must be viewed in light of gene flow and selection, which define units of genetic similarity, and of phenotype and ecological function, respectively. We discuss to what extent ecological and genetic units overlap to form cohesive populations in the wild, based on recent evolutionary modeling and on evidence from some of the first microbial populations studied...

A sensitive and reproducible method for assay of antidiuretic activity, described in this paper, yielded accurate measurements in the range 60 to 540 micropressor units of pitressin, corresponding to about 15 to 130 micropressor units of arginine-vasopressin. The method differs from previous techniques mainly in using urine density, rather than urinary flow rates, as the index of response.

Current Graphic Processing Units (GPUs) (circa. 2003/2004) have programmable vertex and fragment units. Often these units are implemented as SIMD processors employing parallel pipelines. Data dependent conditional execution on SIMD architectures implemented using processor idling is inefficient. I propose a multi-pass approach based on conditional streams which allows dynamic load balancing of ...

This paper establishes a new mobile electronic toll collection (m-ETC) by integrating mobile communication with radio frequency (RF) communication on microprocessor control with an e-commerce business model. A simple ETC system architecture and protocol for e-transactions from vehicles to toll stations is proposed to complete toll interaction on wireless environment. A software flow through Int...

Electronic Control Units (ECUs), such as for automotive engine control, execute highly interdependent software units. These software units and their interaction are optimized for single-cores and need to be parallelized for upcoming multi-core processors. In this paper we investigate how to leverage the parallelism of the physical environment for the parallelization of legacy control software. ...

We present results from a BeppoSAX observation of the cooling flow cluster Abell 2029. The broad band spectrum (2–35 keV) of the cluster, when fitted with a model including a cooling flow component and a one temperature thermal component, yields a temperature of 8.3±0.2 keV and a metal abundance of 0.46±0.03 in solar units, for the latter. No evidence of a hard X-ray excess is found in the PDS ...

J Comput Assist Learn. 2018;1–14. Abstract Educational robotics programs offer an engaging opportunity to potentially teach core computer science concepts and practices in K–12 classrooms. Here, we test the effects of units with different programming content within a virtual robotics context on both learning gains and motivational changes in middle school (6th–8th grade) robotics classrooms. Si...

One of the most important methods of transporting natural gas in Iran and other parts of the world is the utilization of a network of pipelines. Compression station and turbo compressor units play an important role in gas supply through pipelines. One of the primary concerns in these units is the reduction of fuel consumption. By cooling of exhaust gas from the source station, the pressure ...
