The proposed circuit technique is developed using simple source-coupled differential pair transconductors and linear reference resistor (R). As a result, an efficient linearization of a transfer characteristic of the OTA is obtained. The gm - programmability of the developed OTA was obtained using a programmable current mirror array technique. SPICE simulations show that for 0.35 mum AMS CMOS process with a single +3 V power supply, total harmonic distortion (THD) at 1Vpp and temperature range from -30degC to +90degC is less than -35.8dB. Moreover the input voltage range of linear operation is increased. Power consumption of the linearized OTA circuit is 0.76 mW.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127627000","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}

We introduce a new model for inferring phylogenies which is a generalization of the widely studied perfect phylogeny model. The perfect phylogeny model assumes that a feature shared by a set of species cannot have evolved independently in any two of the species in the set, i.e. the species with this feature form a subtree in the correct phylogenetic tree. We briefly review earlier similar results on this subject and describe the difference between our model and the ones previously investigated. It turns out that the problem of finding a perfect phylogeny with restrictions is NP-complete even if the number of characters is 2. This contrasts with the complexity of finding unrestricted perfect phylogenies. On the other hand, the new model shows similar properties to the classical perfect phylogeny model in case where the number of cycles in each state transition graph is bounded by a small constant.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132529456","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 analysis is based on the measurement investigations of the radio signal loss made for different propagation conditions of the container terminal environment. Two main types of the propagation environment have been take into account - i.e. LOS and NLOS conditions, as typical for the environment classification. New empirical formulas for the propagation loss calculations appropriate to these types of the propagation environment have been proposed. To obtain these formulas the measurement investigations have been made and the multidimensional regression analysis has been applied. The new propagation model has been verified by use of the measurement investigations.

The first part of the study focuses on data preparation. Bitmaps containing musical symbols are converted to feature vectors using various methods. The vectors created in such a way are used to train classifiers which are the essential part of the study. Several decision tree classifiers are applied to this recognition task. These classifiers are created using different decision tree induction methods. The algorithms incorporate different criteria to select attributes in the nodes of the trees. Moreover, some of them apply stopping criteria, whereas the others perform tree pruning. The classification accuracy of the decision trees is estimated on data taken from musical scores. Eventually the usefulness of decision trees in the recognition of printed musical symbols is evaluated.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133698540","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 success of this knowledge discovery process depends critically on the quality of samples and their associated data. Biological samples are expensive to collect and store. The samples and their associated data pass through a number of processes, generally in multiple locations, from data collection from the participant, to clinical laboratory analyses, to processing in the research laboratory (proteomics, metablomics, etc.) and ultimately to knowledge discovery. The samples are moved in and out of freezers at several different points in this workflow. The potential for errors in sample identification and linking the corresponding data to its sample is therefore very high. This paper describes a novel method based on Radio Frequency Identification (RFID) technology to support secure and reliable tracking of both samples and data which minimises the potential for error. The samples are labelled with RFID tags, which allow location-independent recording and updating of sample data as they move along the workflow. The system is linked to a web-based database, which provides the ability to identify and locate individual or group of samples rapidly.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115946718","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}

Nevertheless, among all knowledge forms, storing decisional experience in a knowledge-explicit way becomes an important advance. We introduce the decisional DNA as a reflexive knowledge structure able of capturing organizations' decisional fingerprints in the form of explicit decisional experience. The construction of the decisional DNA is a journey that starts with a decisional event. This decisional event builds up a Set of experience knowledge structure (SOEKS) establishing a decisional gene. Multiple decisional genes comprise decisional chromosomes, and multiple decisional chromosomes lead to the construction of the decisional DNA of an organization. In addition, current implementations and future trends of the decisional DNA are presented through the introduction of emerging semantic technologies and applications turning the decisional DNA into a reflexive knowledge structure.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127214298","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}
