Through internet information can be disseminated and retrieve from any location regardless of the political and geographical boundary.The ease of the internet encourages institutions of higher learning to employ the internet to support students' learning.Many studies have been conducted to access students, perception towards the internet usage.This paper aim to re-access the student usage of the internet to support their learning.The assessment is vital in order to understand students' internet usage as different group of student may perceive internet differently.Undergraduate students were chosen as they are among the active group if internet user.The findings show that all students are actively using internet to fulfill their academic requirement and social needs.The findings reflect that most of the undergraduate students pay high responsibility towards the use of internet as this facility is freely provided by their institution of higher learning.
The inhibiting bisection problem.

A densitometer with a controllable light emitter intensity operates to reduce excessive exposure of sensitive materials, such as photoconductive film. During normal printer operation, the emitter is operated in a pulsed-mode, thereby reducing emitter temperature and prolonging its useful life. Exposure of the photoconductor is also reduced, which may prolong its useful life and avoid image defects. The pulse width, frequency, and duty-cycle are chosen to give these benefits without compromising density measurement capability. The emitter drive circuitry is connected to a motion sensor so that emitter intensity is reduced to a low level when photoconductor motion is stopped. A test mode is provided during which the emitter intensity is reduced by a calibrated amount, simulating the presence of a calibrated test sample.
STUDY OF COMPUTER MANUAL INPUT DEVICES

Abstract : A study of computer manual input devices and their associated human engineering characteristics was conducted for the purpose of developing a scheme for relating these devices to operator performance characteristics, computer characteristics and system requirements. Conventional commercially available input devices such as pushbuttons, toggle switches, joysticks, etc. were surveyed. Available literature pertaining to human performance with such devices was reviewed and summarized. The suitability of devices and availability of applicable performance data are related to a generalized operator task family by a set of tables. Results of the study show a wide variety of available devices, inadequate research data establishing performance for various devices and device character istics, and incomplete specification of operator input tasks in existing systems.
Analysing Data Access Strategies in Cache Coherent Architectures

The conception of multiprocessor systems based on shared memory is to provide logically uniform data access, even in systems with many processors. Since data requests that cannot be satissed physically within the processor environment suuer from high latencies, these systems employ memory hierarchies including private caches. Two powerful techniques that reduce and hide latency in memory hierarchies are buuer-ing and pipelining of data accesses. In order to utilize these techniques in global shared-memory architectures, new memory consistency models have been deened. In this paper, we discuss the cache coherence problem and three consistency models that are commonly used to enhance performance. We develop a uniform parameterized model for diierent parallel architectures and estimate the latency for data access in each consistency model abstracting from the details of hardware mechanisms. The goal of our approach is to obtain realistic predictions of running-times for the various models.
Querying Persistent Graphs using Solid State Storage

Recent advances in solid state technology have led to the introduction of Solid State Drives (SSDs). Todays SSDs store data persistently using NAND flash memory. While SSDs are more expensive than hard disks when measured in dollars per gigabyte, they are significantly cheaper when measured in dollars per random I/O per second. Additional storage technologies are under development, Phase Change Memory (PCM) being the next one to enter the marketplace. PCM is nonvolatile, it can be byte-addressable, and in future Multi Level Cell (MLC) devices, PCM is expected to be denser than DRAM. PCM has lower read and write latency compared to NAND flash memory, and it can endure orders of magnitude more write cycles before wearing out. Recent research has shown that solid statedevices can be particularly beneficial for latency-bound applications involving dependent reads. Latency-bound applications like path processing in the context of graph processing or Resource Description Framework (RDF) data processing are typical examples of these applications.We demonstrate via a custom graph benchmark that even an early prototype Phase Change Memory device can offer significant improvements over mature flash devices (1.5x - 2.5x speedup in response times). We take this observation further by building Pythia, a prototype RDF repository tailor-made for Solid State Storage to investigate the predicted benefits for these type of workloads that can be achieved in a properly designed RDF repository. We compare the performance of our repository against the state of the art RDF-3X repository in a limited set of tests and discuss the results. We finally compare the performance of our repository running on a PCM-based device against a state of the art flash device, showing that there is indeed significant gain to be achieved by using PCM jfor RDF processing.
The Art of Neighbours Gaming: Facebook, Fan-Crafted Games and Humour

Australian soap opera Neighbours (1985-present) has a history of attracting a 'cult' following who often enjoy the programme partly because they feel able to 'laugh at' it - often including teenagers, students and young adults (Wober and Fazal 1994: 85; Williams 2010). In that spirit, Facebook group, 'The Art of Neighbours' (AoN) was launched in 2007 (see Bury et al 2013). Members submit 'artwork' dedicated to the show - however, unlike the more 'serious' fan art of other communities (see Bacon-Smith, 1992; Jenkins, 1992), AoN's tribute is deliberately low-tech and humorous: 'We have decided to represent our love for it through the refined medium of MS Paint. If you want to have a go at creating a beautiful tribute to your favourite character, then you can submit it to our gallery for all to see and worship. ' (Art of Neighbours 'About' page). Images submitted are usually satirical, although the group points out 'We freakin' love Neighbours and all the actors and would hate to think this is how we ACTUALLY see them. SO, everything in here is made in jest'. The humorous artwork frequently extends to crafting and gaming, with a yearly 'Secret Santa' and occasional meets during which members have created Neighbours-themed board games (including Connect 4, Cluedo and Top Trumps), often using 'art' created in the group, or group in-jokes about the characters. In this paper I explore the ways board game creation has been appropriated as a method of fan creativity, humour, gifting and interaction (including the gifting of games to actors in the show) - and the way Neighbours producers use social media to encourage the playfulness. The AoN group operates in this way as a site of fannish 'play' (Hoge, 2011) allowing people to express fandom in a way that is deemed 'appropriate' for the 'non-serious' fan object.
Characterization and processing of atrial fibrillation episodes by convolutive blind source separation algorithms and nonlinear analysis of spectral features

Las arritmias supraventriculares, en particular la fibrilacion auricular (FA), son las enfermedades cardiacas mas comunmente encontradas en la practica clinica rutinaria. La prevalencia de la FA es inferior al 1\% en la poblacion menor de 60 anos, pero aumenta de manera significativa a partir de los 70 anos, acercandose al 10\% en los mayores de 80. El padecimiento de un episodio de FA sostenida, ademas de estar ligado a una mayor tasa de mortalidad, aumenta la probabilidad de sufrir tromboembolismo, infarto de miocardio y accidentes cerebrovasculares. Por otro lado, los episodios de FA paroxistica, aquella que termina de manera espontanea, son los precursores de la FA sostenida, lo que suscita un alto interes entre la comunidad cientifica por conocer los mecanismos responsables de perpetuar o conducir a la terminacion espontanea de los episodios de FA. El analisis del ECG de superficie es la tecnica no invasiva mas extendida en la diagnosis medica de las patologias cardiacas. Para utilizar el ECG como herramienta de estudio de la FA, se necesita separar la actividad auricular (AA) de las demas senales cardioelectricas. En este sentido, las tecnicas de Separacion Ciega de Fuentes (BSS) son capaces de realizar un analisis estadistico multiderivacion con el objetivo de recuperar un conjunto de fuentes cardioelectricas independientes, entre las cuales se encuentra la AA. A la hora de abordar un problema de BSS, se hace necesario considerar un modelo de mezcla de las fuentes lo mas ajustado posible a la realidad para poder desarrollar algoritmos matematicos que lo resuelvan. Un modelo viable es aquel que supone mezclas lineales. Dentro del modelo de mezclas lineales se puede ademas hacer la restriccion de que estas sean instantaneas. Este modelo de mezcla lineal instantanea es el utilizado en el Analisis de Componentes Independientes (ICA).
Standardization of the Complement/Adjunct Distinction

This paper[a] reports on criteria for distinguishing complements from adjuncts in the development of COMLEXSyntax[b], a large on-line syntactic lexicon of English. Correct, or at least consistent, criteria are crucial for lexicographyand natural lan­ guage processing. Complement/adjunct criteria from linguistics and lexicography leave a gray area optional complements are difficult to distinguish from adjuncts. In an experiment we conducted, four graduate students make substantially the same Complement/Adjunctdistinctions for 205 examples using our criteria. 1. Lexicography and the Complement/Adjunct Distinction Since complements, but not adjuncts, should be listed in lexical entries of verbs, it is important that lexicographers have clear criteria. In our view, Longman's Dictionary of Contemporary English (Proctor 1978, referred to below as LDOCE) makes this distinction adequately (although we are unsure what criteria they use). However, we have detected some errors in making this distinction in the Oxford Advanced Learner's Dictionary (Hornby 1980, referred to below as OALD). For example, (la, b, c, d) each contain a subordinate clause (gerundal or infinitival). The bracketed adjunct phrases in ( la , b) are adjuncts (OALD marks them as comple­ ments), but ( lc , d) are complements. The adjunct clauses are optional and can occur with a wide variety of verb phrases with much the same meaning as in (la, b). In contrast, the complement clauses are obligatory for the relevant meanings of ( lc , d). (1) (a) He opened the door [to let the cat out] (OALD, p. xxxvi) (b) She lay [smiling at me] (OALD, p. xxx) (c) He started [to let the cat out] (d) She continued [smiling at me] Herbst (1984, 1987, 1988) distinguishes complements and adjuncts for lexicography, using a few of the same criteria that we do, but we use many more criteria overall. Herbst also draws on different sources than
Authorship Identification and Verification of JavaScript Source Code: An Evaluation of Techniques

The increasing number of criminals that exploit the speed and anonymity of the Web has become of increasing concern. Little effort has been spent to trace the authors of malicious code. To that end we investigated authorship identification and verification of JavaScript source code. We evaluated three character based approaches and propose a new domain specific approach. What is new in the domain specific analysis approach, is that it represents code by a parse tree to extract structural features. The evaluation of the techniques with open source code from GitHub, turned out that the approaches that use character n-gram features achieved the best performance. However, the combination of n-gram and domain specific features turned out to be complementary, resulting in a higher performance. Techniques that used similarity based classification were especially successful if a limited amount of training data were available, while feature vector based techniques were mainly successful when a large amount of training data were available and in an authorship verification context. By means of code minification we evaluated how the classification accuracy is affected by removing authorship information from the source code. Code minification has shown to significantly deteriorate the performance of the authorship analysis methods. Especially the compression based technique is robust against code minification.
Mobile Augmented Reality

Mobile Augmented Reality bezeichnet die Anreicherung von realen Bildern mit computergenerierter Zusatzinformation in mobilen Szenarien. Die Information wird in Echtzeit über das abgefilmte Bild eines Tablets oder über das tatsächliche Sichtfeld einer Person gelegt. Um eine gute Nutzererfahrung zu gewährleisten, sind eine Reihe besonderer Herausforderungen zu bewältigen: falls dreidimensionale, dynamische Objekte wie Lebewesen dargestellt werden sollen, müssen deren physikalische Eigenschaften modelliert und das Resultat in der richtigen Perspektive und Beleuchtung dargestellt werden. Dafür müssen auch die Position realer Objekte verfolgt, die Beleuchtung und die eigene Position und Perspektive geschätzt werden. Augmented Video wird als der nächste Schritt, der all diese Techniken benötigt, gesehen. Während heutige Augmentierung oftmals in schlichtem Einblenden von Inhalt über statische Objekte besteht, sollen in Zukunft wesentlich komplexere Aufgaben aus dem Bereich der Computer Generated Imagery (CGI) verrichtet werden. So soll es beispielsweise möglich sein, die Farbe eines vorbei fahrenden Autos in der augmentierten Ansicht durch eine beliebige andere zu ersetzen. Weitere Informationen zu Augmented Reality finden sich im Paper ”A Survey of Augmented Reality Technologies, Applications and Limitations” (Link). Bei einigen der angebotenen Themen sind Demos mit Google Cardboard möglich. Dafür sind zwei Einheiten geplant, in denen sich alle Teilnehmer mit der Datenbrille vertraut machen. Die geplanten Vortragsthemen für die Teilnehmer sind:

Abstraction-based certification of temporal properties of software modules

When an untrusted program (termed a module in the dissertation) is executed on a host system, the correctness of the integrated system, in particular, the security, is of concern. Many security or correctness properties can be expressed in temporal logic. Certification of temporal properties provides a piece of evidence (termed a certificate in the dissertation) that helps the host system reverify a property of concern. Examples of the applications of such certification include extensions of an operating system kernel with API safety guarantees. Previous solutions, where certificates are primarily proofs, suffer from the problem that the sizes of the certificate do not scale as the programs become larger and the properties become more complicated. We propose Abstraction-carrying code (ACC) as an alternative certification method to the traditional proof based approaches. ACC uses an abstract interpretation of the module as a certificate. Using abstraction methods from the software model checking community, we can compute an abstract model that demonstrates that a program satisfies a temporal property; the size of such an abstract model tends to scale well when the complexity of problem increases. A module will carry this abstraction as a certificate; a client receiving the code and the certificate will first validate the abstraction and then run a model checker to verify the temporal property. We report our efforts in building the ACC Evaluation and Prototype Toolkit (ACCEPT). Two versions of ACCEPT, ACCEPT/While and ACCEPT/C, target a simple While language and C, respectively. Novel aspects of our work include: (1) the use of a Boolean program (BP), a useful abstraction of a program, as a certificate, (2) the simultaneous compilation of the source program and the BP to generate a BP for compiled code, (3) the encoding of the BP as index types, a powerful type system that can specify and check strong program properties, and (4) the semantics-based validation of the BP through index type checking. We report our experience of applying ACCEPT to various programs, including Linux and NT drivers. Our investigation shows that ACC tools generate certificates that scale better compared to those generated by other techniques of similar expressive power and that the time spent on model checking is acceptable for supporting many applications.
Cortisol: funcions i importància del receptor glucocorticoide : una visió comparada

Les hormones corticoesteroides son essencials per a la regulacio d'una gran varietat de processos fisiologics. El cortisol es el principal corticoesteroide en peixos teleostis, amb funcions glucocorticoides i mineralocorticoides. Es el principal indicador de la resposta a l'estres, i la principal hormona en el control de l'osmorregulacio en peixos, especialment per a l'adaptacio a l'aigua marina. Tambe interve en la regulacio de la resposta inflamatoria inhibint la produccio de citocines despres d'una infeccio experimental per l'endotoxina dels bacteris gramnegatius o LPS. Una infeccio experimental per LPS desencadena una reaccio immunitaria innata que activa una resposta inflamatoria. Les citocines produides en resposta a aquesta infeccio activen l'eix hipotalamic-pituitari-interrenal (HPI) mitjancant l'activacio de l'hormona adrenocorticotropa (ACTH) i l'alliberacio de cortisol. Tambe, els efectes de les hormones corticoesteroides estan regulats a traves de receptors intracell. ulars especifics que actuen com a factors de transcripcio dependents del lligand i activen diferents gens implicats en la resposta a l'estres. Aquests receptors son el receptor de tipus i o receptor mineralocorticoide (MR) i el receptor de tipus ii o receptor glucocorticoide (GR). Per tant, la comunicacio neuroimmunoendocrina en els vertebrats es crucial per a mantenir l'homeostasi i el receptor de cortisol hi te un paper clau.
Learning to Follow Navigational Route Instructions

We have developed a simulation model that accepts instructions in unconstrained natural language, and then guides a robot to the correct destination. The instructions are segmented on the basis of the actions to be taken, and each segment is labeled with the required action. This flat formulation reduces the problem to a sequential labeling task, to which machine learning methods are applied. We propose an innovative machine learning method for explicitly modeling the actions described in instructions and integrating learning and inference about the physical environment. We obtained a corpus of 840 route instructions that experimenters verified as follow-able, given by people in building navigation situations. Using the four-fold cross validation, our experiments showed that the simulated robot reached the correct destination 88% of the time.
ADVANCEMENT OF UPPER EXTREMITY PROSTHETIC INTERFACE AND FRAME DESIGN

DESIGN Randall D. Alley, B.Sc., C.P. Hanger Prosthetics and Orthotics, Inc. ABSTRACT Although traditional upper extremity prosthetic interface and frame (collectively referred to here as “interface”) designs have enabled many individuals to integrate prostheses into their rehabilitation plan, the biomechanical attributes and other parameters of these designs have not been significantly reviewed and improved upon until recently. In the last decade, a multitude of design innovations have been incorporated, which have resulted in wearers reporting superior comfort, suspension, stability, and range of motion, among other advantages. In most cases, when paired with a variety of control systems, the new designs appear to be inherently more efficient in terms of force transmission and motion capture, and more functionally consistent than traditional types of “sockets”. It is the intention of this paper to highlight these novel design elements, as well as to discuss the biomechanical principles involved, to enable prosthetic users and other individuals to better understand these advanced interfaces.
