Three types of language models were considered - a common n-gram model, an n-gram model of lemmas and a class n-gram model. The last two types were specially designed for the Serbian language reflecting its unique grammar structure. All the language models were trained on a carefully collected data set incorporating several literary styles and a great variety of domain-specific textual documents in Serbian. Language models of the three types were created for different sets of textual corpora and evaluated by perplexity values they have given on the test data. A log-linear combination of the common, lemma-based and class n-gram models that was also created shows promising results in overcoming the data sparsity problem. However, the evaluation of this combined model in the context of a large vocabulary continuous speech recognition system (LVCSR) is yet to be done in order to establish the improvement in terms of word error rate (WER).","PeriodicalId":207630,"journal":{"name":"2012 IEEE 10th Jubilee International Symposium on Intelligent Systems and Informatics","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123361432","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}

CPR is hanged on four points and it is able to follow and record a moving object with high precision wherever the object moves in its workspace. Each contribution is a step closer to the achievement of highly automated systems which would precisely lead camera in the area with as less involvement of human interference as possible. Two new CPR structures are proposed. The mathematical model (kinematic and dynamic) is defined for both versions of the solution. It is assumed that all the parameters of systems are the same and therefore the comparison of these systems will be easier. It is evident that the choice of construction of CPR significantly affects the response of this system.","PeriodicalId":207630,"journal":{"name":"2012 IEEE 10th Jubilee International Symposium on Intelligent Systems and Informatics","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129423892","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}

In the modeling process it can be assumed that the motion occurs in a two-dimensional space and the object can be driven forward or backward. In the foreseen task, the robot must reach a target point by some predefined specific control requirements. The simplified kinematic bicycle model of a four-wheeled robot car, mentioned in [1] has been upgraded for the purposes of this research. It has been observed that the simplified model was not sufficiently adequate and accurate. Reference [1], besides the previous simplified model, also contains a P route controller. A new Fuzzy route control has been applied, because it was more customizable compared to the simple PID control. This article describes a comparison of the results between P and Fuzzy controllers. Based on the results obtained it has been concluded that it would be worthwhile to further develop this model and control system.","PeriodicalId":207630,"journal":{"name":"2012 IEEE 10th Jubilee International Symposium on Intelligent Systems and Informatics","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126722673","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}

In many applications, it is required to know geographical location of the sensor which detected an event. The existing localization algorithms can be classified into two categories: range-based and range-free. Range-based algorithms measure the actual distances between nodes, while range-free algorithms approximate the distance based on connectivity information. Range-free localization is cost-effective alternative to a more expensive range based approaches since there is no necessity for additional hardware. However, these techniques usually have higher localization error compared to the range-based algorithms. DV-Hop is one of the range-free localization algorithms utilizing hop-distance estimation. In this paper, we propose an improvement of the range-free DV-Hop localization algorithm and present simulations results to evaluate it.","PeriodicalId":207630,"journal":{"name":"2012 IEEE 10th Jubilee International Symposium on Intelligent Systems and Informatics","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128337131","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}

Glitch generator, switched ring oscillator, buffer and pulse shaping filter are the key components. The circuit is scalable both in bandwidth and center frequency. The glitch generator combines falling edge of the input signal and its delayed inverse, allowing the impulse duration to be tuned over a wide range (250-660 ps) by varying the delay between the edges. The generated impulse duration approximately defines the PG's signal width and thus its spectrum bandwidth. The ring oscillator frequency, which determines the spectrum center frequency, is controlled by the gate control voltage of the PMOS transistor used as an inverter feedback in the ring oscillator. Post-layout simulations show the pulse amplitude of 261 mV and the pulse duration around 700 ps. The total power consumption is only 697 μW with a supply voltage of 1.8 V.
