The research and development of selective analytical systems, not requiring pre-treatment of samples and rapidly providing information in real time, is receiving increasing attention in various areas of human life (Chen et al, 2011;Palmisano et al, 2000;Maestre et al, 2005;Jia et al, 2004;Surareungchai et al, 1999;Tsai & Doong, 2005;Gülce et al, 2002;Akin et al, 2011;Mishra et al, 2012). For ex...

The title compound, [[Ti(C(2)H(10)N)(2)(C(11)H(10)N(3))(2)] or Ti(C(11)H(10)N(3))(2)(NEt(2))(2)], was prepared by direct reaction of 2-(N-phenyl-methyl-imino-meth-yl)-1H-imidazole and [Ti(NEt(2))(4)]. The Ti(IV) atom is in a pseudo-octa-hedral coordination environ-ment with the imidazolido-group N-atoms occupying apical positions and amido- and imino-N-atoms cis-located in the equatorial plane....

A nonparametric learning algorithm is used to build a robust mapping between an image obtained from a mobile robot s on board camera and the robot s cur rent position The mapping uses unprocessed pixel values by pixel image Because the learning algorithm is nonparametric it uses the learn ing data obtained from these raw pixel values to au tomatically choose a structure for the mapping with out...

One of the most promising opportunities in troduced by rapid advances in knowledge based learning environments and multimedia technolo gies is the possibility of creating animated peda gogical agents These agents should exhibit three properties timely domain coverage they should clearly communicate fundamental concepts and relationships within the allotted time contextu ality they should provid...

Reinforcement learning RL algorithms pro vide a sound theoretical basis for building learning control architectures for embedded agents Unfortunately all of the theory and much of the practice see Barto et al for an exception of RL is limited to Marko vian decision processes MDPs Many real world decision tasks however are inherently non Markovian i e the state of the environ ment is only incomp...

Different modeling formalisms for timed and hybrid systems exist, each of whichaddresses a specific set of problems, and has its own set of features. These for-malisms and tools can be used in each stage of the embedded systems development,to verify and validate various requirements.The Compositional Interchange Format (CIF), is a formalism based on hybridautomata, which...

In our research we explore the role of negotia tion for con ict resolution in distributed search among heterogeneous and reusable agents We present negotiated search an algorithm that ex plicitly recognizes and exploits con ict to direct search activity across a set of agents In nego tiated search loosely coupled agents interleave the tasks of local search for a solution to some subproblem inte...

16 17 In eubacteria, trigger factor (TF) is the first chaperone to interact with newly synthe-18 sised polypeptides and assist their folding as they emerge from the ribosome. We report the 19 first characterisation of a TF from a psychrophilic organism. TF from Psychrobacter frigidi-20 cola (TF PF) was cloned, produced in Escherichia coli and purified. Strikingly, cross-linking 21 and fluoresce...

Corrosion is the destructive result of reaction between a metal or metal alloy and its environ‐ ment [1-3]. Metal atoms in nature are present in chemical compounds (i.e, minerals). The same amounts of energy needed to extract metals from their minerals are emitted during the chemical reactions that produce corrosion. The corrosion process (anodic reaction) of the metal dissolving as ions genera...

Objective To review external fixation in the management of war injuries. Method We prospectively followed up 15 external fixators (14 patients) applied in the management of war injuries. All these patients were treated at 202 Field Hospital during the 2003 Gulf Conflict. Results Of the 15 fixators, 13 (86.7%) required early revision or removal due to complications of the injury or the fixator. ...
