Learning adjectives and nouns from affordances on the iCub humanoid robot

This article studies how a robot can learn nouns and adjectives in language. Towards this end, we extended a framework that enabled robots to learn affordances from its sensorimotor interactions, to learn nouns and adjectives using labeling from humans. Specifically, an iCub humanoid robot interacted with a set of objects (each labeled with a set of adjectives and a noun) and learned to predict the effects (as labeled with a set of verbs) it can generate on them with its behaviors. Different from appearance-based studies that directly link the appearances of objects to nouns and adjectives, we first predict the affordances of an object through a set of Support Vector Machine classifiers which provided a functional view of the object. Then, we learned the mapping between these predicted affordance values and nouns and adjectives. We evaluated and compared a number of different approaches towards the learning of nouns and adjectives on a small set of novel objects. The results show that the proposed method provides better generalization than the appearance-based approaches towards learning adjectives whereas, for nouns, the reverse is the case. We conclude that affordances of objects can be more informative for (a subset of) adjectives describing objects in language. © 2012 Springer-Verlag

Affordance prediction of hand tools using interactive perception [Etkileşimli görsellik kullanilarak el aletlerinin saǧlarlik tahmini]

In daily life, the selection of a hand tool for a job depends on appereance of the tool and its effect on the objects. The effect determines the affordance of the chosen tool. Aim of this work is to determine the affordances of hand tools based only on their appereance and to build a basis for simple tool usage of humanoid robots. Towards this end, in this work from the functional regions of human interacted hand tools, sharpness, bluntness, distance between two tip and grayscale histogram features are extracted and specific affordance models are trained. The features of a hand tool which its affordances wanted to be learned are given to the trained models to determine which affordances that the tool has like can cut, can push, can squeeze, can pierce. During testing, the model predicted the affordances %93.1. From this results it can be said that, this model sets a basis for simple tool usage of humanoid robots. © 2012 IEEE

Objectives: To examine the histologic structure of major salivary glands in high-fat diet induced hyperlipidemic rat

Colon surgery in gynecologlc oncology [Ji·nekoloji·k onkoloji·de kolon cerrahi·si·]

Objective: To discuss the benefits, morbidity and mortality and the indications for colon resection in gynecologic oncology especially in cytoreductive ovarian cancer operations and to present a case series. Materials and methods: We reviewed 120 patients who underwent gynecologic oncology operations between 2008-2009 in Ege University Hospital. Colon surgery was performed 14 of them.(%11.6) The mean age of patients who had colon surgery were 58.2(37-77). Two patients underwent surgery besides ovarian carcinoma; one of them with the diagnosis of endometrium adenocarcinoma and the other with primary tubal adenocarcinoma. All the others were (n=12) operated with the diagnosis of ovarian carcinoma. Results: Rectosigmoid tumor extirpation and primer anastomosis (n=1), colostomy (n=1), appendectomy (n=3), tumor extirpation from sigmoid mesentery (n=5), tumor extirpation from transvers colon mesentery (n=1) and rectovaginal tumor extirpation (n=1) was performed. In three of the patients the dissection of adhesions was performed without any damage to colon with the aim of optimal cytoreduction. Serious hemorrage occured in one patient due to use of anticoagulation drugs at the fourth postoperative day. Conclusion: Although studies demonstrated that optimal cytoreductive surgery provides longer survival in ovarian cancer patients, patient's medical and physical conditions like age, systemic illness, chemotherapy history are also important for morbidity and mortality

Electrical, optical and theoretical characterization of doped and undoped calamitic liquid crystal: (s)-5-octyloxy-2-[[[4-(2-methyl butoxy) phenyl] imino] methyl] phenol

The electrical conductivities of undoped and doped calamitic liquid crystalline compound, (S)-5-octyloxy-2-[[[4-(2-methylbutoxy) phenyl] imino] methyl] phenol (OMPIMP) with tetrabutylammonium tetrafluoroborate as dopant were determined as a function of temperature. Optical studies of undoped and doped OMPIMP thin films were also carried out using spectrophotometer. Optical band gaps of doped and undoped OMPIMP thin films were determined through absorption spectra using Tauc plot. The frontier orbital energies; E-HOMO, E-LUMO and the band gap energies were calculated from the DFT calculations which were carried out by the hybrid B3LYP functional

Case management based multidisciplinary care protocol in the palliative care of cancer patients [Kanser hastasinin palyatif bakiminda vaka yönetimine dayali multidispliner bakim protokolü]

PubMed ID: 24943853Today, multifaceted approach is needed for the palliative care of advanced stage cancer patients. The main objective for these patients, elimination of pain and other symptoms, psychosocial and spiritual needs are met and to increase the quality of life. We are also faced with the challenge of meeting the physical and psychosocial needs of family members. The purpose of a holistic approach to patient and family who provide effective and quality care, care coordination and case management of a multidisciplinary team approach is based on cooperation. Care protocols specified patient care activities to be carried by the related disciplines to achieve results on a timeline that shows a certain, a multidisciplinary clinical management tool. A lot of care guidelines and protocols developed by a team of experts to contribute to the palliative care activities, and this is thought to be a guiding team members, working with patients
