Synchronisation et auto-étalonnage de plusieurs caméras fixées sur un casque

Cet article propose des methodes de synchronisation et d'auto-etalonnage pour plusieurs cameras grand public fixees sur un casque, sans utiliser de mire ou de cible. L'hypothese principale est que toutes les cameras ont la meme configuration (frequence, resolution d'image, angle de champs de vue, et approximativement equiangulaires). On synchronise d'abord en utilisant le fait que toutes les cameras ont le meme mouvement de rotation au meme instant. Ensuite, tous les parametres extrinseques et intrinseques sont raffines par Structure-from-Motion et un ajustement de faisceaux. Nos experiences incluent des evaluations quantitatives et des videos urbaines acquises avec une multi-camera fait maison (4 cameras GoPro fixees sur un casque), de sorte que l'on obtienne un champs de vue de 360 degres dans le plan horizontal.

Building a programs' evaluation system by using CBR Cased Based Reasoning

It is very important to a company to select the best program based on its needs, especially there are hundreds of programs, similar in general, different in price and functions. Many companies do only comparing between those programs, trying to select the best on this comparison. This article aimed to suggest an software evaluation system, to select the best program based customer's needs, using Cased based Reasoning- CBR- techniques, and associations Rules, in addition to evaluate these programs internally, and find the similarity rate between customer's needs and program's features. The evaluation system depends on a number of questions, have to be answered by the vendors, to specify their program features, after that the customer will answer also the same questions, to determine his needs, and give a weight related to each question. At the end, the evaluation system will select the best program, that has the top rank based on the similarity between customer's needs and program features.
A Switched Capacitor based Micro-stimulator for Deep Brain Stimulation

Gaurav, Bawa. A Switched Capacitor based micro-stimulator for Deep Brain Stimulation. (under the direction of Dr. Maysam Ghovanloo and Dr. Leda Lunardi) This thesis presents a novel technique for the development of an implantable stimulator for Deep Brain Stimulation. The key idea is to harvest energy from an inductive link using an efficient switching mechanism at the secondary side. To validate the concept, extensive characterization was performed by simulating explicit differential equations in MATLAB in addition to a prototype implementation in standard CMOS technology. In principle, a zero current switching methodology at the secondary coil has proved to be extremely energy efficient due to no extra wastage of power in the parallel resonant circuits. A high efficiency full-wave rectifier has been implemented in standard CMOS technology, which ensures a measured efficiency of ~ 85 % while delivering ~ 19 mW of power to the load at 500 KHz input frequency. The underlying principle is that of synchronous rectification, minimization of MOS switch resistance through biasing in deep triode and blockage of reverse currents from the load to source using a lossless capacitive voltage divider technique. Dual-mode backtelemetry has been incorporated in a full-wave active rectifier with minimal area overhead and an increased data rate and reading range in measurement results, when the rectifier loading varies over time.
Looking for the Spaceless Book, an E-publishing Archaeology

In the reformulation of the ‘publication’ concept after the electric and then electronic revolution, there is a consequent reformulation of the ‘space of publication’ which finally transcends the page and the binding as the insurmountable limits.Here the history of this process is tracked through the first optical attempts to compress the content in order to overcome those limits, conceptually preparing for a more radical technological shift. Foreseen in early science fiction visions, this shift determined by digital and the networked technologies, is dramatically collapsing the publication space towards a dimension close to the infinite, where the published object disappears in the reading machine, in what becomes a mere but sophisticated ‘container’.
The Human Dentition Before Birth

Until the appearance of this text, little documented evidence of antenatal dental morphology was available. The authors, drawing on the unique collection of fetal material at the University of Pittsburgh, have carried out an unusually thorough investigation with the data well supported. Their study of ontogenetic development is based on whole embryonic crowns stained with alizarin red S. which provided specimens that could readily be examined morphologically and eliminated the tedious reconstruction from serial histological sections.
New Cryptography Algorithm with Fuzzy Logic for Effective Data Communication

In this communicative world, people forget to care about the security when the data communication gets the importance than the privacy most of the time. There the data theft takes place effortlessly. Many methodologies have been devised for making the effective communication either over the internet or intranet. However, the hackers enrich themselves than the new technologies whenever are launched. As need arises for cultivate the security key generation while secure data communication has to be ensured, we propose a new cryptography algorithm along with the fuzzy logic through this paper that materializes the secure communication possible. Firstly, we observed the flaw that causes for hacking effortlessly by the intruder during the data transmission over the network. Then the evaluation part could be done with the same context without losing data because of this proposed algorithm. This algorithm concentrates on image and text data encryption using fuzzy logic and on secured sharing theme which provides highly authenticated data transferring. The existing security algorithms had nod in many ways only for the secure data transmission rather than the complexity in which they have when need to be executed. Henceforth the aspirants who want to have the communication have to spend more time than the actual. Obviously the precious algorithms should have less processing time and high secure in nature. With keeps it as a main aspect the New Cryptography algorithm with fuzzy logic is proposed and has low process time and high security logics using various key for encryption and decryption. The results which produced by this proposed algorithm have been compared with exist algorithms and finally could arrive the conclusion that the proposed is highly effective in security aspects and needs minimum amount of time to be executed.
The sentence production test for aphasia

Background: Researchers and clinicians have long known that in aphasia, the ability to produce connected speech is poorly predicted by tests of single-word production. Connected speech is most commonly assessed using rating scales, in which the examiner rates the speech on various fluency-related and grammatical well-formedness measures. However, with this method, interrater and test–retest reliability can be poor, and since the intended utterance is not known, accuracy and appropriate of the speech content is difficult to measure. Aims: The aim of the present study was to develop and investigate the validity and usefulness of a new, freely accessible sentence production test (SPT) based on simple pictured event description. Methods & Procedures: The SPT involves describing simple pictured events. The test pictures represent a range of sentence constructions and lexical items, which elicited high response agreement in healthy controls. The simple automatised scoring procedure generates both general and specific accuracy measures. This article describes the test construction and norming procedure and reports test data from 24 participants with aphasia. Outcomes & Results: Interrater reliability for the scoring protocol was excellent. The overall sentence score was found to measure unique variance not accounted for by single-picture naming. It was unrelated to fluency measures such as speech rate. Specific scores, such as the closed-class score, measure partially overlapping, but qualitatively distinct constructs from other speech assessments. Conclusions: The SPT is quick to administer, easy to score and can be used even when a person’s speech is very limited. It provides a range of measures of sentence production that may prove informative for both clinical and research purposes.
Grasp control of a prosthetic hand through peripheral neural signals

The use of neural electrodes to stimulate the Peripheral Nervous System (PNS) of upper limb amputees is giving promising results in restoring tactile feedback. The same interfaces could be used to record the motor activity originated from the brain and transferred to the muscles. In this paper, the possibility to control a prosthetic hand by means of neural signals acquired through tf-LIFE4 electrodes implanted in a human subject was investigated. A Support Vector Machine (SVM) algorithm was adopted to classify two common demanded grasps. The obtained classes were converted into reference positions for a position-and-slippage control strategy that guarantees to perform stable grasps with a prosthetic hand avoiding slippage events. The achieved results showed an accuracy of the classifier higher than 90% and a success rate of the control strategy equal to 100%.

Polipose múltipla familiar: análise de 44 casos tratados no Hospital das Clínicas da FMRP-USP

The authors present a retrospective analysis of forty-four patients with familiar adenomatosis polyposis treated at the School of Medicine of Ribeirao Preto Hospital and Clinics - University of Sao Paulo, from January 1991 to July 2005. Epidemiologic (age and gender) and genetic aspects were investigated as well as main symptoms, personal history and surgical treatment outcome. Data obtained were compared to the available literature. Our results show that 31 patients were male and 13 female, with average age of 32 years-old (14 to 60 years-old). The main symptoms were intestinal bleeding (62.5 %) and intestinal habit alteration (60 %). Less frequently, patients showed abdominal pain (45 %) and loss of weight (30 %). Familiar adenomatosis polyposis was reported by 67.5 % of the patients and relatives with neoplasms (intestinal and extra-intestinal) were referred by 62.5 % of the patients. By the time of the polyposis diagnosis, 32.5 % of the patients have already been diagnosed for colon cancer, with average age of 39 years old. Surgical treatment was performed in 95.4 % of the patients, total proctocolectomy was performed in 35.7 % (9 cases with ileal J- pouch and 6 with permanent ileostomy) and total colectomy with ileo rectal anasthomosis in 59.2%. From all patients evaluated, 57 % are still under follow up, 7 % died and 27 % gave up treatment.
Low bit rate coding using an interpolated zinc excitation model

Prototype excitation vocoding has been of particular interest, particularly at bit rates below 4 kbits/sec where conventional analysis by synthesis (AbS) LPC based coders fail to deliver the speech quality required in a number of new voice communication applications and services. The present authors propose a new time domain, interpolated zinc function prototype excitation technique (IZFPE) for communications quality speech at about 2.0 kb/s. In this method a prototype pitch segment is selected every 20 ms. Each prototype segment is then modelled by a zinc orthogonal function which is derived by employing a closed loop AbS procedure (ZFE-AbS). Successive prototype zinc excitations are then interpolated such that the characteristics of the resulting excitation signal evolve slowly with time. <<ETX>>
Interrelationships Among Attentional Preferences, Cardinal-Ordinal Ability, and Conservation of Number.

HENRY, DONALD E. Interrelationships among Attentional Preferences, Cardinal-Ordinal Ability, and Conservation of Number. CHILD DEVELOPMENT, 1976, 47, 750-758. Cardinal-ordinal abilities and attentional preferences of kindergarten nonconservers, kindergarten conservers, and third-grade conservers of number were compared by employing standardized versions of Piagetian cardinal-ordinal tasks and a triad preference task on which Ss were asked which 2 of 3 rows of poker chips were "the same. " The triad contained arrays which were each alike on 1 stimulus dimension (e.g., number) and different on the other 2 dimensions (e.g., length and density). Kindergarten conservers preferred the dimension of number significantly more often on the preference task, had number more readily available on probe trials of the preference task, and performed significantly better on cardinal-ordinal tasks than did nonconservers. Third-grade conservers preferred the dimension of number significantly more often on the preference task, had number and density more available on probe trials, and performed significantly better on a cardinal-ordinal task that called for operational understanding.
PREMIERES OBSERVATIONS HISTOLOGIQUES DE L'OVIDUCTE DE BOULENGERULA TAITANUS, LOVERIDGE 1935, AMPHIBIEN GYMNOPHIONE

Boulengerula taitanus est une espece ovipare de Gymnophione, habitant les terrains humides des monts Taita du Kenya. L'histologie de l'oviducte des femelles, preleve en saison de reproduction, revele une structure tripartite, typique des Amphibiens ovipares, composee d'une pars recta, d'une pars convoluta et avant le cloaque, d'une pars utera. Les techniques classiques d'histologie et d'histochimie permettent de distinguer le contenu cytoplasmique des cellules glandulaires de l'epithelium oviductal. Elles permettent aussi d'analyser la structure et la composition de la gangue des œufs retrouves dans l'oviducte. Il apparait alors que la premiere couche de cette enveloppe, etant de nature plutot glycoproteique, a ete produite par les cellules glandulaires de la pars convoluta. Quant a la seconde, plus externe, elle est composee de proteoglycannes sulfates et acides et provient donc de la pars utera. Ces resultats revelent les specificites de B. taitanus en la rapprochant toutefois, d'une autre espece de Gymnophione etudiee, Ichthyophis glutinosus.
Making Sense of Mobile Eye-Tracking Data in the Real-World

Stationary eye-tracking technology has been used extensively in human-computer interaction to both understand how humans interact with computers and as an interaction mechanism. Mobile eye-tracking technology is becoming more prevalent, yet the analysis and annotation of mobile eye-tracking data remains challenging. We present a novel human-in-the-loop approach for mobile eye-tracking data analysis that dramatically reduces resource requirements. This method incorporates human insight in a semi-automatic decision making process, leveraging both computational power and human decision making abilities. We demonstrate the accuracy of this approach with eye movement data from two real-world use cases. Average accuracy across the two environments is 82.3%. Our approach holds tremendous promise and has the potential to open the door to more robust eye movement studies in the real-world.
On closed-loop liveness of discrete event systems under maximally permissive control

A class of controlled discrete-event systems that can be modeled as cyclic controlled marked graphs (CMGs), a special case of control Petri nets, is considered. Liveness of the controlled system under the maximally permissive feedback control is examined. In the CMG context, closed-loop liveness implies that from any reachable marking (state), any transition can be enabled to fire. The concept of synchronic distances in Petri nets is used to prove sufficient conditions under which the maximally permissive control results in a live closed-loop system. <<ETX>>

Role of Laparoscopy in the management of gallbladder cancer

Minimal Access approaches have become established in nearly all fields of surgery, gastroenterology and cardiology because of obvious advantages to the patients. The cardinal benefits include-significantly less post-operative pain, reduced requirement of postoperative analgesia, decreased hospitalization and earlier return to normal activities. Following the development of laparoscopy to treat benign surgical diseases, its role has expanded lately for the surgical management of malignancies. The use of laparoscopy in cancer patients is the subject of increasing excitement and controversy. The issues of safety of laparoscopic procedures in cancer patients have been debated and some settled (port site recurrence). Carcinoma of the gallbladder is a highly fatal disease with a overall 5-year survival rate of 5 percent -10 percent. The mainstay of therapy for gallbladder cancer (GBC) is conventional surgery. Incidental GBC has been reported following laparoscopic/open cholecystectomy for benign gallbladder disease. Laparoscopic cholecystectomy may be therapeutic in patients with incidental gallbladder cancer of early stage (T1a). However gallbladder cancer beyond Stage 1a i.e. Ib, II, III and IV all require completion conventional surgery in the form of liver resection of segment IV and V with portal lymphadenectomy. The role of laparoscopy in the management of GBC is largely diagnostic. The diagnostic laparoscopy is being increasingly used in patients with known or highly suspected GBC to assess the resectability, staging and avoiding unnecessary laparotomy in inoperable cases.
Autonome Fahrzeugführung in urbaner Umgebung durch Kombination objekt- und kartenbasierter Umfeldmodelle

Eine vollstandig automatische Fahrzeugfuhrung im allgemeinen Strasenverkehr fasziniert Techniker wie Nichttechniker bereits seit der Fruhphase des Automobils. Ein Stuck naher an die Realitat wurde diese Vision durch die DARPA Urban Challenge im November 2007 gebracht. Die Entwicklung der Fahrzeugplattform Caroline fur die Teilnahme an der DARPA Urban Challenge bildet den Rahmen fur diese Dissertation. Die Systemarchitektur zur Bewaltigung der komplexen Fahraufgabe wird in vier elementare Funktionsebenen zur Wahrnehmung, Situationsinterpretation, Aktionsplanung und Aktionsausfuhrung untergliedert. Um ein Verstandnis fur die Funktionsweise des Gesamtfahrzeugs zu ermoglichen, wird insbesondere auf die enge Verzahnung der Komponenten eingegangen. Eine Schlusselrolle in der Fahrzeugarchitektur nimmt die maschinelle Wahrnehmung der Fahrzeugumgebung ein. Aufbauend auf den theoretischen Grundlagen der bayes’schen Informationsverarbeitung wird ein hybrides Umfeldmodell entwickelt, indem sowohl herkommlich-objektbasierte als auch kartenbasierte Modellierungsverfahren zum Einsatz kommen. Die Ansatze werden erweitert fur eine Funktion im innerstadtischen Umfeld. Hierbei wird ein Freiform-Objektmodell zur Hinderniserkennung sowie eine kartenbasierte Fahrbereichsanalyse eingefuhrt, im Rahmen der Situationsinterpretation erfolgt eine Kopplung dieser Online-Umfelddaten mit zusatzlich bereitgestellten, digitalen Navigationsdaten. Das Freiform-Objektmodell ermoglicht die Beschreibung beliebiger Hinderniskonturen und unterscheidet sich somit von klassischen, quaderbasierten Objekthypothesen aus dem Bereich der Fahrerassistenzsysteme. Die Fahrbereichsanalyse ermittelt den urbanen Strasenverlauf durch Fusion von LIDAR- und Kamerasensorik in einer probabilistischen, Dempster-Shafer basierten Gridkarte. Das beschriebene Fahrzeugsystem konnte als eines der 10 besten Fahrzeuge aus dem Verlauf der Urban Challenge hervorgehen.
