Recent drought saw more than 1% of the nation's economy lost and resulted in unprecedented widespread water scarcity. Four power generation scenarios were evaluated for 2050 regarding their impacts on water and land resources. This analysis reveals that the mutual dependencies of water, energy and land are gaining in importance and cannot be managed effectively without cross-sect oral integration. The findings suggest that a diversification of electricity generation technologies with the expansion of photovoltaic and wind power can help limiting additional land and water requirements for future power supply.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"391 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122986332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wireless Mesh Network consists of either a wireless or wired backbone network from which Mesh Gateways (MGs), Access Points (APs), wireless Mesh Routers (MRs) and Mesh Client (MCs) are linked together through carefully designed topologies. WMN networks have the advantage of high reliability, scalability and low capital outlay. The H.264/AVC standard is a joint standard for video compression promoted by the International Telecommunication Union Telecom Sector and the ISO/IEC. The H.264/AVC standard specifies four video formats: Common Intermediate Format (CIF), Quarter CIF (QCIF), Sub Quarter CIF (SQCIF) and 4CIF. Results in this work show that flow throughput is half the network throughput when the hop count for a given topology is two. Additionally, at fixed number of nodes, the Tree Mesh topology outperformed the Fork Mesh and Cross Mesh topology by a factor of 2.8 and 7 in End-to-end and jitter terms respectively.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124396943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Includes a four-mass structure for the mechanical part. Discusses how to identify the mechanical resonance frequency using two signals: PRBS (pseudo random binary sequence) and chirp. The result is a nonparametric model from which is determined the resonant frequency. Knowledge of resonance frequencies allows to tune determine digital filter for resonance damping. The filter is inserted between the speed controller and current controller. The article discusses the method of determining the delay caused by the filter. Knowledge of total delay is used in the synthesis of the speed controller. In paper were analyzed following filters: notch, reversed resonance characteristics and low-pass. The exact formulas for the group delay was derived for the notch filter. In the last stage of research the control system was tested. Speed set point was less than 1 res/s.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124632231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While team planning and cooperation is essential for the success of the goal of the game, it also plays an essential role in enhancing the believability of the game. Our serious game is in the domain of emergency management, fire fighters in accidents situations. Two contributions are presented in this paper, firstly, enhanced visual perception system that mimic center of attention in humans eye for each NPC along with a short-term memory (working memory) so that NPCs will have access to only limited information and have to build their plans and make their decisions based on what they can perceive from their surrounding environment. Secondly, a distributed HTN planning approach is implemented based on SHOP for the domain of our serious game. Five modules were developed in this part, Controller, World Model, Domain, Interface and HTN Planner. There is two level of planning, team level plans and individual level plans. Plans are generated online based on the information gathered from the visual perception system and stored in the working memory. Our experiment shows The effectiveness of the proposed approach to generate plans.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114551382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The role of the web server is usually to pass results and data between a front-end web browser and specialised back-end computation software which carries out the actual simulations and analysis. More recent versions of the web scripting languages have the computational capabilities required for power systems analysis and can handle the responsibility of modelling networks and analysing them. This provides an opportunity for a slimmer 2-tier framework in which the web server also acts as the application server thereby reducing the server resources required and simplifying access to modelling functions. A methodology for carrying out power flow calculations on a web server using PHP is described in this paper and the outcome is a PHP application library for carrying out such analysis. The library may be easily included in PHP web applications that require specific power systems analysis functions thereby allowing them access this functionality without relying on third party software separate from the web server on which they already run. The performance of the application library is also measured and discussed.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133572784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This leads to many interesting characteristics, including a memory of its past states, demonstrated in its resistance. Smaller area and power consumed by memristors compared to conventional memories makes them a more suitable choice for applications needing large memory. In this paper we explore one of the unique properties of memristors which extends their suitability by allowing storage of multi-bit data in a single memristor. Their ability of storing multi-bit patterns will be shown via a simplified proof and simulations. This characteristic can be advantageous for many applications. In this paper particularly, we briefly discuss its advantages in pattern learning applications.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"234 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133426435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, such level of integration leads to many physical limit and transistors cannot get much smaller than their current size. Quantum-dot Cellular Automate is a novel technology which significantly reduces physical limit of CMOS devices implementation, thus, it can be an appropriate candidate to be substituted for CMOS technology. In addition to high integration density of QCA circuits, other unique specifications such as high speed and low power consumption encourage researchers to utilize this technology instead of CMOS technology. In this paper, a new layout of XOR gate is presented in QCA technology, then, it is exploited to design an 8-bit controllable inverter. Finally, using the proposed design and last adder circuit provided by ourselves in our previous work, an 8-bit adder/subtract or is designed. It is the most important component of an ALU. All the designed circuits have used coplanar clock-zone based crossover. The most prominent characteristics of designed circuits include very high operation speed, very low complexity, small area, completely coplanar design, and also avoiding rotated cells in us designs for Avoidance of Construction Challenges QCA Circuits. The mentioned characteristics are considerably improved in our proposed structure comparing to its counterparts.

One way to address these defies is by investing in the training of plant operators. Traditionally, operator training was done informally through on-the-job techniques and has been improved trough time. Simulators were included as a part of training and have proved to be efficient and effective. It has also been found that their use results in savings caused by availability, thermal performance, plant life, and environ-mental compliance of the simulated processes. Despite its benefits, a simulator does not guarantee a successful training unless a program based on a systematic approach to training is used, this maintains a continuous improvement in the stages here proposed (analysis, design, development and support, integration, implementation and evaluation) considering the simulator explicitly. Having an integral instruction centre with adequate personnel and material infrastructure is helpful to exploit both, simulators and training system. These centres, among other things, must be designed so that the simulator may: exchange data with modern commercial external programs to support the training program, consider the evolution of simulators technology (for example, with immersive or non-immersive virtual reality), and expand the simulators considering analysis and optimisation capabilities. A review of the present situation of all these topics is exposed in this paper.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116404615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
