The crack-compliance method is an effective means of measuring the inherent residual stresses in EW75M plates. However, the complexity of calculating the compliance matrix in the data processing makes this method impossible for engineering applications. In order to complete modeling in pre-processing and results extracting in post-processing automatically in finite element software ABAQUS, the finite...
The socioeconomic impact of limb disabilities produced by injuries, traumas or congenital defects is evident in low-income countries, where there are often inadequate systems of trauma care and rehabilitation. The most medical schools in developing countries do not include a disability and rehabilitation component in their curricula. Even worst, many institutes do not have facilities or equipment...
A good methodology flow can improve significantly the time needed to develop an I/O library. It is mandatory that the fastest methodology also gives accurate results. Given the new technology nodes, it is important to re-evaluate all the software characterization formats (NLDM, CCS and ECSM) and see if there is room for improvement. The analysis will be conducted by comparing liberty file data with...
The use of cognitive maps in support of solving practical problems of analysis of ill-structured situations and large-scale systems in economics, medicine, ecology, education and military-political sphere is growing. The problem of visual perception and understanding of cognitive maps is proven to be extremely urgent and practically important. The set of visualization methods that provide better perception...
The paper presents recent technological advancements that have been made by Siemens PLM in its simulation tools for multi-body analyses and multi-physics simulation in order to run physics-based high fidelity models in real-time. The motivation is enable reuse of simulation models developed during the engineering phase during the validation phase with hardware or humans in the loop. To demonstrate...
This paper presents an analysis of advancing a code compliant single detached dwelling in Ontario, Canada to Passive House Standard energy efficiency level. The research was based on comparing energy models built with the Passive House Planning Package, and included thermal bridging calculations performed in the THERM software. For each energy model, only the effect of improved exterior insulation...
The article describes the methodology developed for a data warehousing process developed in a Chilean University. The purpose of the process is to generate indicators of academic productivity. For this a methodology is elaborated integrating diverse approaches techniques and methodologies such as: specification of information requirements relational modeling combined development model of Kimball and...
Customer demand for electricity supply is vastly increasing due to urbanization and changing needs. Thus electrical utilities need to accurately determine load profiles for different sectors of the supply area, so that new customers can be seamlessly added. To obtain such information a customer connectivity model needs to be developed and implemented such that historical customer data from various...
In order to increase the load capacity of aerostatic bearings, a kind of continuous slot-restriction aerostatic thrust bearing was designed and manufactured. The CFD simulation and experiment methods were both used for studying it; the data about the load capacity was derived from the two methods. The calculation results of the CFD simulation method were compared with the experiment ones. The following...
The use of semi-physical simulation platform for school laboratory and classroom building scene a lot of field measurements, analysis of power line channel transmission characteristics of the different environments, and features a three-dimensional graphic display of variable power line channel under different scenarios. At the same time in order to improve the efficiency of the data analysis, the...
In order to cope with the rising complexity of today's systems, model-based development of software-intensive embedded systems has become a de-facto standard in recent years. Such a development approach enables a variety of frontloading methods. Design space exploration is one of those techniques. However, in order to properly perform a valid exploration, a system model has to have a certain quality...
Phase-shifting reactor (PSR) can be used to solve the harmonic problems caused by rectifiers. In this paper, according to the active power balance principle, the relationships among DC current of load, currents of power supply side, as well as capacity of core limb are built, and the design specifications of winding and core are obtained. simulation of 6-phase rectifier system with PSR by the equivalent...
Nowadays applications need to deal with a large number of concurrent requests. These systems must be stress tested to ensure that they can function correctly under a load. In this context, a research field called Search-based Software Testing has become increasingly important. Most of the search-based test methods are based on single objective optimization. In the case of multi-objective optimization...
The renewable energy sources are promising to take a significant share in the energy sector as a viable option for integration with conventional fossil fuel power plants. This paper contributes to the ongoing studies about grid-connected solar photovoltaic (PV) system and draws attention to the optimal design and sizing considering several techno-economic factors including net present cost, cost of...
Novel architectures for massively parallel machines offer better scalability and the prospect of achieving linear speedup for sizable problems in many domains. The development of suitable programming models and accompanying software tools for these architectures remains one of the biggest challenges towards exploiting their full potential. We present a multi-layer software abstraction model to develop...
The visual simulation system which the docking process of replenishment at sea is constructed based on MultiGen Creator and Vega Prime. In a bid to modeling and driving of the visual simulation, a large number of the real-time data should be transformed for simulation in which the entire process of replenishment at sea. According to the complicated power and movement state of the docking mechanism...
This paper presents the work performed at (removed for blind review) to automate the integration of virtual systems development (VSD) and simulation in its embedded software development process. The approach is based on a combination of metamodels, model transformations and design patterns, the SysML standard and the use of the open source Eclipse framework. The purpose is to derive all the design...
In the electricity sector, new sides have emerged with the development of technology and the increasing the electric energy need. Today, electricity has become a product that is bought and sold in the market environment. Forecasting which is the first step of plans and planning have become much more important and have been made mandatory for the market participants by energy market regulators. In...
In this paper we propose a new internationalization model for databases. This model is intended to enable the internationalization (i18n) in a database, thus facilitating the work of both the database developer as well as the translator which performs its localization (l10n). The use of this model should reduce the developer's effort and allow the translator not to worry about application implementation...
This paper joins the developing trend of modeling distributed generators based on dq0 quantities, and proposes an open-source software for modeling and analysis of large-scale power networks based on dq0 signals. The dynamic models describing the network are provided as state-space objects that are sparse and of minimal order. The software supports integration of various models of synchronous machines,...
