This BCI-VR system prototype was functionally tested on multiple participants and demonstrated live before an audience during the 2017 ‘Hack the Brain’ at the Dublin Science Gallery. The availability of a low cost, effective, BCI-VR solution targeted at researchers and developers, which is capable of analysing a subject’s BCI performance and presenting neurofeedback VR to a level acceptable for academic and industry experimentation, has the potential to open up this field to much wider range of researchers and could help increase the functional outcomes for stroke rehabilitation.","PeriodicalId":174854,"journal":{"name":"2018 29th Irish Signals and Systems Conference (ISSC)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132762007","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}

A total of six switches are positioned on the top of the design to perform re-configurability in three ways. The proposed antenna offers re-configurability from 1750 MHz to 1870 MHz for return loss below −10 dB which can be used in Korean Personal Communication Systems wireless (PCS) applications. The MIMO parameters like mutual coupling, envelope correlation coefficient, and diversity gain are presented to validate the performance of the antenna.

The model facilitates the analysis of PSR by combining the individual PSRs of each analog block through the frequency dependent gain of the following blocks. Since bandgap reference generators, voltage to current generators, and voltage buffers are crucial blocks in analog systems, they are chosen to be the case of study to validate the theory developed in this work. With no loss of generality, the method can be applied to any chain of analog blocks under assumption of linear operation. The circuit used to explain the concept is implemented in 0.25-µm CMOS technology.","PeriodicalId":174854,"journal":{"name":"2018 29th Irish Signals and Systems Conference (ISSC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117143920","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 use of 28-nm CMOS technology poses new challenges on low phase noise DCO design. Supply voltages are further reduced to 0.9 V in order to not to damage the devices, resulting in a lower voltage swing and higher achievable phase noise with respect to higher supply voltage designs. In addition, very stringent local density rules, even required to meet in small inductor and capacitor areas, add an extra difficulty to layout a DCO, so the way the inductor is laid out becomes an essential step during the design to obtain the desired performances. The presented DCO achieves a phase noise equal to -127 dBc/Hz at 1 MHz offset from its central oscillation frequency of 1.3 GHz, achieves a tuning range of 1.25 GHz to 2.25 GHz with a fine frequency resolution of 1.1 MHz and consumes the total power of 5 mW using a 0.9-V supply. The layout area is 280 µm × 530 µm including the inductor. Finally, the tuning range-based Figure Of Merit (F OMT ) is equal to 194 dB.","PeriodicalId":174854,"journal":{"name":"2018 29th Irish Signals and Systems Conference (ISSC)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126841910","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 miniaturized radar has the ability to see through obstacles in the line of sight. To achieve 3D visualization, we developed, integrated and tested a custom digitally steered phased-array antenna system designed for ultra-wideband (UWB) frequencies. A 3x3 array of Vivaldi antennae was fabricated on three separate printed circuit boards including 1x3 arrays each. Time Domain’s PulsON 440 was the chosen radar measurement platform due to its small form factor, its high depth resolution and its high bandwidth capabilities. The key performance metrics of the antennae were simulated including reflection coefficients and radiation patterns and compared with the measured results of the fabricated system. A digital logic system was designed using a Teensy microcontroller to control the beam steering of the antenna platform. A Matlab program was written to synchronise the PulsON 440 and the beam steering control and to output the 3D image data in real time including some signal processing. Experiments were performed to display the resolution and accuracy of the See-Through Wall radar images.","PeriodicalId":174854,"journal":{"name":"2018 29th Irish Signals and Systems Conference (ISSC)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124635214","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 antenna comprises of a cross-shaped dielectric resonator, fed by two orthogonal probes. Adjacent to both probes, two rectangular micro strip patches are stacked to the walls of DRA to enhance the return loss and improve the impedance matching. Two C-shaped deformations are made on the ground plane. Four PIN-Diodes are located on the C-shaped deformations. Re-configurability is achieved when PIN-diodes are switched OFF or switched ON. The re-configurability is attained for two resonance frequencies. For the configuration I, the antenna resonates at 1.84 GHz but the overall bandwidth covers GSM 1900 MHz. For the configuration II, the antenna resonates at 2.08 GHz but the total bandwidth includes frequencies, which can be used for LTE/UMTS 2100 MHz applications. The antenna performance is analyzed in terms of simulated return loss, radiation pattern, diversity gain and envelope correlation function.

While this problem has been studied over the past thirty years, previous topic segmentation studies ignore crucial elements of a conversation: an opening and closing remark. Our motivation to revisit this problem space is the rise of instant message usage. We consider the problem of topic segmentation as a machine learning classification one. Using both enterprise and open source datasets, we address the question as to whether a machine learning algorithm can be trained to identify salutations and valedictions within multi-party real-time chat conversations. Our results show that both Naïve Bayes (NB) and Support Vector Machine (SVM) algorithms provide a reasonable degree of precision(mean F1 score: 0.58).","PeriodicalId":174854,"journal":{"name":"2018 29th Irish Signals and Systems Conference (ISSC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116991731","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}
