Single-carrier FDMA (SC-FDMA) multiple access scheme has been chosen for the 3GPP LTE uplink scheduling. However, it requires that all the sub carriers allocated to a single user must be in contiguous frequency band within each time slot. This constraint limits the scheduling flexibility. The resource allocation algorithm in frequency domain must take this constrain into consideration to maximize its scheduling objectives. An Efficient Resource Allocation algorithm with Grey Relational Analysis (ERAGRA) is proposed and compared with the others algorithms based on the throughput and fairness in this research. The ERAGRA algorithm is a channel-aware traffic resource allocation algorithm which aims at enabling uplink traffic delivery on ideal and non-ideal channels. This algorithm is evaluated using 3GPP LTE simulation model. A key performance index (KPI) is defined as the combination of total throughput and fairness. ERAGRA and two other scheduling algorithms: Best CQI and Round Robin has been evaluated through simulation based on this KPI. Simulation results indicate that the proposed ERAGRA algorithm effectively improves the average normalized system throughput of Best CQI by 6.22 % and fairness by 2.74 %, while improves the average normalized system throughput of Round Robin by 38.67 % and fairness by 10.26 %. The proposed scheduling scheme achieves a near optimal solution for maximizing system throughput and fairness of resource utilization.","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124092125","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}

Four tasks were completed. First, PP as the major binder, replaced with some EVA, to improve the flexibility of the filaments. The compatibility of PP and EVA was also investigated by grafting maleic acid (MA) on PP chain to reduce different polarity between PP and EVA. The third task was to study the dispersion condition of the alumina powder in feedstocks, and quantitatively investigated the influence by kneading sequences, solid content, and other processing parameters.

SSVEP is an evoked signal which responds to visual flickering stimuli at a specific frequency. A stimulus panel containing 12, 15, 18 and 28-Hz flickering stimuli was presented in front of users. Each flickering stimulus was used to evoke SSVEP and responded to a particular command for the wheelchair control. The power spectrum densities (PSDs) for the specific frequency bands were analyzed. A target stimuli was triggered when the PSD exceeded a defined threshold. Users were able to drive the wheelchair with forward, stop, left-turn and right-turn commands according to their intentions. Additionally, a reactive navigation scheme based on artificial potential field (APF) approach was implemented to improve the security of the proposed system. A laser scanner was outfitted for obstacle detections. The proposed wheelchair system is expected to provide a convenient, safe and comfortable mobile assistance to users suffering spinal cord injuries (SCIs).","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125246873","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}

Among the different HVDC technologies, voltage source modular multilevel converter (VSC-MMC) provides the highest power quality, modularity, availability and, additionally, it enables the implementation of multi-terminal HVDC (MTDC). These MTDC systems require a control system which can manage the power exchange among different HVDC stations keeping the DC voltage between certain limits. Previously proposed controllers, such droop control, usually requires adaptive algorithms to tune the controller parameters. On the other hand, constant dc voltage control provide low reliability because only one station controls the voltage of the complete dc line. In this paper, the control of an MTDC system based on VSC-MMC stations is proposed. A set of power and voltage limits are defined for each station, as well as the information related to allowed operation modes. The controller in one station does not require information from other stations because its operation mode and references depend on its own local variables. Simulation results which validate the proposed control strategy are shown.","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132377352","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 uncertain processing time and routings make MRO scheduling differ greatly from traditional manufacturing. Simulation optimization is suitable to solve the problems with uncertainty. This work uses multi-fidelity optimization with ordinal transformation and optimal sampling framework to solve a MRO scheduling problem. We build a high-fidelity simulation model which is stochastic and time-consuming. Instead of directly running the high-fidelity model, we provide a deterministic low-fidelity model to transform the original solution space into a one-dimensional ordinal space. The transformed solution space is partitioned into several groups. An efficient optimal computing budget allocation method is used to sample within these groups. Numerical results and comparisons show that this framework is computationally effective to handle those uncertainties, and provides high quality schedules with the low tardiness for the MRO scheduling problem.","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133772189","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}
