Gaze control in humans: eye-head coordination during orienting movements to targets within and beyond the oculomotor range.

Gaze, the direction of the visual axis in space, is the sum of the eye position relative to the head (E) plus head position relative to space (H). In the old explanation, which we call the oculocentric motor strategy, of how a rapid orienting gaze shift is controlled, it is assumed that 1) a saccadic eye movement is programmed with an amplitude equal to the target's offset angle, 2) this eye movement is programmed without reference to whether a head movement is planned, 3) if the head turns simultaneously the saccade is reduced in size by an amount equal to the head's contribution, and 4) the saccade is attenuated by the vestibuloocular reflex (VOR) slow phase. Humans have an oculomotor range (OMR) of about +/- 55 degrees. The use of the oculocentric motor strategy to acquire targets lying beyond the OMR requires programming saccades that cannot be made physically. We have studied in normal human subjects rapid horizontal gaze shifts to visible and remembered targets situated within and beyond the OMR at offsets ranging from 30 to 160 degrees. Heads were attached to an apparatus that permitted short unexpected perturbations of the head trajectory. The acceleration and deceleration phases of the head perturbation could be timed to occur at different points in the eye movement. 4. Single-step rapid gaze shifts of all sizes up to at least 160 degrees (the limit studied) could be accomplished with the classic single-eye saccade and an accompanying saccadelike head movement. In gaze shifts less than approximately 45 degrees, when head motion was prevented totally by the brake, the eye attained the target. For larger target eccentricities the gaze shift was interrupted by the brake and the average eye saccade amplitude was approximately 45 degrees, well short of the OMR. Thus saccadic eye movement amplitude was neurally, not mechanically, limited. When the head's motion was not perturbed by the brake, the eye saccade amplitude was a function of head velocity: for a given target offset, the faster the head the smaller the saccade. For gaze shifts to targets beyond the OMR and when head velocity was low, the eye frequently attained the 45 degrees position limit and remained there, immobile, until gaze attained the target.

Recovering Use-Case-Diagram-To-Source-Code Traceability Links

Use case diagrams (UCDs) are widely used to describe requirements and desired functionality of software products. However, UCDs are loosely linked to programs source code, and maintaining traces between the source code and elements of UCDs is a manual, tedious, and laborious process. We offer a novel approach for automating a part of this process. Developers first specify few traceability links (TLs). Our system combines these links with run-time monitoring, program analysis, and machine-learning approaches to recover and validate additional TLs between types and variables in Java programs and elements of UCDs. We evaluate our prototype implementation on opensource software projects, and our results suggest that our approach can generalize from a small set of initial links to recover many other TLs with a high degree of automation and precision.
Memory-Based Concordancer for Mongolian Toponym

This paper presents methods and principles used in a computer-based concordancer of Mongolian toponym. The search engine reads the headwords that are previously built from the database of Mongolian toponym in the concordance form and then writes it into the memory as hash-table structure, and uses it for further searching. Search word could be selected from the headwords table or typed in Mongolian or its Roman transcription form. Therefore, the system could perform multiword searching with and/or condition. The system itself was written in C# language, thus it supports the Unicode environment.
Analysing Learner Behaviour through Logfiles for Quality Assurance and Student Evaluation

Learning environments provide extensive logging capabilities that document learner activities. Careful interpretation of these logs can be used for quality assurance and student evaluation. We present a logfile processor that reads Toolbook logfiles and collects data for determining “hot spots” (i.e. particularly good or bad spots) in a course or in learner behaviour. Hot spots show up as extreme values during the analysis; they are candidates to be looked at by instructional design experts. The logfile processor’s methods for data collection can be customised using an event mechanism. Its output — either flat ASCII or structured XML — is further analysed: We present exemplary diagrams based on logfiles from a sample course.
Intelligent Decision Support for Business Workflow Adaptation due to Subjective Interruption

Interruption is occurred by partial participation of workflows with adding new activity to a worker. A concerned worker to the interrupted workflow must restructure task assignment to improve consumed operating time by interruption. An opportunity of decision making is occurred to the workers to select appropriate tasks. However, preassignment of tasks to workers includes an expectation of superior decision maker to a training of an inexperienced worker. In order to avoid overmuch improvement to the interrupted workflow, the alternatives for shortening operating time of tasks is computed by TOPSIS method. Although positive ideal solution and negative ideal solution in conventional TOPSIS method are based on objective attributes, subjective completion time of pre-assigned tasks that are positive ideal solution in this model is depending on subjective attributes of the worker. Therefore, this research proposes a novel extension of positive and negative ideal solution of TOPSIS method by aggregating based on subjective fuzzy attributes of the worker and objective attributes of tasks. The approach is examined on simple case study showing that the work is promising on providing solution to handle interruption on carried work in runtime.
Combining Forecasts using Clustering

Given sales forecasts for a set of items along with the standard deviation associated with each forecast, we propose a new method of combining forecasts using the concepts of clustering. Clusters of items are identified based on similarity in their sales forecasts and then a common forecast (or combined forecast) is computed for each cluster of items. The objective of clustering is to minimize the mean square error (MSE), which is the sum of the variance and squared bias of the combined forecasts. It is easy to show that combining forecasts from a group of items generally decreases the variance but increases the bias of the combined forecast. A new clustering method is proposed based on this tradeoff between the decreased variance and increased bias. A useful property of the proposed clustering method is that it automatically finds the right number of clusters. On a real dataset from a national retail chain we have found that the proposed method of combining forecasts produces significantly better sales forecasts than either the individual forecasts (forecasts without combining) or an alternate method of using a single combined forecast for all items in a product line sold by this retailer.
A Case of Systemic Lupus Erythematosus Presenting as Guillain-Barré Syndrome

Systemic lupus erythematosus (SLE) is an autoimmune systemic disease with multiple organ involvement with high morbidity and mortality rate. Among the severe potential fatal complications are those of the central and peripheral nervous system which usually develop during the course of the disease and very rarely from the outset of the disease. We are reporting a rare case of Miller-Fisher (MFS) variant of Guillain-Barré syndrome (GBS) as the first manifestation of SLE in a 41-year-old female who progressed to flaccid paralysis with no neurological improvement with initial immunosuppressive therapy, plasmapheresis, and first cycle of intravenous immunoglobulin (IVIG) but with remarkable and complete recovery after the second 5-day course of IVIG.
A compact microstrip antenna by a finite U-shaped ground plane

This paper presents a new miniaturization technology of microstrip antenna. The proposed design consists of a microstrip antenna with a U-shaped patch which is obtained by adding two downward rims at the two radiating edges of the patch and a finite U-shaped ground plane which is obtained by adding two upward rims at the edges of the finite ground plane in the direction of radiating edge. Experimental study was carried out by reducing the distance between the downward rim and the upward rim. Adding two upward rims at the finite ground plane, a significant lowering of resonant frequency is obtained with a no reduced operational gain in comparison to the antenna without adding two upward rims. With the design a resonant frequency reduction of 19.7% is obtained and the antenna gain can reach to 5.8dBi at the resonant frequency 906MHz.
Robot Manifolds for Direct and Inverse Kinematics Solutions

We present a novel algorithm to estimate robot kinematic manifolds incrementally. We relate manifold learning with the forward and inverse kinematic of robots. The learned structure encodes this functions and so it is possible to recover them from the manifold. Our algorithm works without any knowledge of the robot kinematics and can potentially work in highly-dimensional spaces. We present some simulated examples to validate our approach.
Graphical Dictionaries and the Memorable Space of Graphical Passwords

In commonplace textual password schemes, users choose passwords that are easy to recall. Since memorable passwords typically exhibit patterns, they are exploitable by brute-force password crackers using attack dictionaries. This leads us to ask what classes of graphical passwords users find memorable. We postulate one such class supported by a collection of cognitive studies on visual recall, which can be characterized as mirror symmetric (reflective) passwords. We assume that an attacker would put this class in an attack dictionary for graphical passwords and propose how an attacker might order such a dictionary. We extend the existing analysis of graphical passwords by analyzing the size of the mirror symmetric password space relative to the full password space of the graphical password scheme of Jermyn et al. (1999), and show it to be exponentially smaller (assuming appropriate axes of reflection). This reduction in size can be compensated for by longer passwords: the size of the space of mirror symmetric passwords of length about L + 5 exceeds that of the full password space for corresponding length L ≤ 14 on a 5 × 5 grid. This work could be used to help in formulating password rules for graphical password users and in creating proactive graphical password checkers.
Design and modeling of mm-wave integrated transformers in CMOS and BiCMOS technologies

Les systemes de communication sans fil en frequences millimetriques ont gagne considerablement en importance au cours des dernieres annees. Des applications comme les reseaux WLAN et WPAN a 60 GHz, le radar automobile autour de 80 GHz ou l’imagerie a 94 GHz sont apparues, demandant un effort consequent pour la conception des circuits integres emetteurs et recepteurs sur silicium. Dans ce contexte, les transformateurs integres sont particulierement interessants. Ils peuvent realiser des fonctions comme l’adaptation d’impedance, la conversion du mode asymetrique au differentiel et la combinaison de puissance. La conception et la modelisation de ce type de transformateur font le sujet de cette these. Une etude detaillee des topologies de transformateurs est presentee, concernant le dessin des inductances, leur position relative, leurs dimensions geometriques, le blindage du substrat et l’obtention de rapports importants de transformation. Leur modelisation par des simulations electromagnetiques et par un circuit electrique a elements discrets est egalement discutee. Le modele presente une topologie 2-π et une serie d’equations analytiques dependant de ses caracteristiques technologiques et geometriques pour evaluer tous ses composants. Un tres bon accord entre les simulations et les mesures est observe pour des transformateurs en technologies CMOS 65 nm et BiCMOS 130 nm jusqu’a 110 GHz. Finalement, les transformateurs sont appliques a la conception d’un melangeur BiCMOS a 77 GHz et un amplificateur de puissance CMOS a 60 GHz.
Domestic appropriations of tokens to the web

We present findings from a study of Tokens of Search, a system comprising physical RFID "tokens" that point to web content, and a wooden tray fixed to a small screen, which can be used to access that content. Three families lived with the system for a month, as an exploration of how tokens might be used as resources for practical action. Our findings highlight existing web practices and their individual and collective nuances; tokens were employed in the creation of short-term collections and long-lasting mementos, their physicality giving bookmarking a visibility that could be used to attract attention, serve as reminders, and make observable progress through tasks. However, while all families saw the potential for shared use, only one used it this way in earnest. We reflect on design choices that were expected to encourage collaboration, and the need to support key users such as parents when establishing joint practices.
Monitoring Personal Data Transfers in the Cloud

Cloud computing brings a number of compliance risks to organisations because physical perimeters are not clearly delimited. Many regulations relate to the location of the data processing (and storage), including the EU Data protection directive. A major problem for cloud service consumers, acting as data controllers, is how to demonstrate compliance to data transfer constraints. We address the lack of tools to support accountable data localization and transfer across cloud software, platform and infrastructure services, usually run by data processors. In this paper we design a framework for automating the collection of evidence that obligations with respect to personal data handling are being carried out in what concerns personal data transfers. We experiment our approach in the Open Stack open source IaaS implementation, showing how auditors can verify whether data transfers were compliant.
Castle of Chips: A New Chip Stacking Structure with Wireless Inductive Coupling for Large Scale 3-D Multicore Systems

The number of stacked chips with wireless inductive coupling interconnect is limited by the physical space for bonding wires of supply voltage. A new chip stacking structure called CoC (Castle on Chips) is proposed for stacking a large number of chips without chip-to-chip wired interconnection. In the CoC, each chip has at least two sets of inductors, and is stacked on two chips in the lower layer shifting in the half chip size. Each chip takes a role of bridge of two chips in the lower layer and two in the upper layer. As examples of the CoC, the linear structure and circular structure are proposed. They form stairway boundary mesh structure, and a simple extension of Dimension Order Routing (DOR) can be deadlock free. The average distance of stairway boundary mesh is better than that of rectangular mesh, and sometimes comparable that of squire mesh. The circular stacking is advantageous when the number of stacking layers is strictly limited.
Improved SNR and ENOB of Sigma-Delta Modulator for Post Simulation and High Level Modeling of Built-in-Self-Test Scheme

This paper demonstrates a Graphical User Interface (GUI) of 2 order Sigma-Delta modulator which is used to check the non-idealities of the circuit in BIST Scheme. High -level modeling of the parameters is done with the help of Matlab Simulink and the parameters like Signal to Noise Ratio (SNR) & Effective Number of Bits (ENOB) are calculated. The value of SNR and ENOB are found to be 108 dB and 18 bits respectively Since the value of SNR and ENOB are increased it makes the respective signal power and Resolution better. The Graphical User Interface (GUI) of overall model has been successfully implemented after modeling of non-idealities for BIST technique not only avoids depending on the off-chip automatic test equipment (ATE) and reduces the test cost but increases the controllability and observability of the circuit under test also that improves the fault coverage .
Personalized Support for Healthy Nutrition Decisions

Despite their high priority, healthy nutrition, physical activity and other preventive health factors are rarely adopted over a long term. Traditional nutrition support systems lack of practical everyday knowledge, social support and motivation as well the consideration of the personal context. We address these impediments with a holistic decision support system that empowers people to change their lifestyle successfully. We aim at analyzing previous approaches from various disciplines and integrating them into one concept for nutrition support giving personalized context aware recommendations to each user while presenting and teaching practical information about healthy nutrition. Additionally, we consider the ease of usage of such an application by automating necessary burdens and motivating participants with social incentives. The decision support system is tested in a 6-month intervention study using regression analysis on usage patterns and matrix factorial designs for interacting features. The social and interactive components are observed in a 1-year field study, utilizing a realistic environment.
WeSpace: the design development and deployment of a walk-up and share multi-surface visual collaboration system

We present WeSpace -- a collaborative work space that integrates a large data wall with a multi-user multi-touch table. WeSpace has been developed for a population of scientists who frequently meet in small groups for data exploration and visualization. It provides a low overhead walk-up and share environment for users with their own personal applications and laptops. We present our year-long effort from initial ethnographic studies, to iterations of design, development and user testing, to the current experiences of these scientists carrying out their collaborative research in the WeSpace. We shed light on the utility, the value of the multi-touch table, the manifestation, usage patterns and the changes in their workflow that WeSpace has brought about.
Achieving dynamic workflow management system by applying provenance based checkpointing method

Scientific workflows are data and compute intensive thus may run for days or even for weeks on parallel and distributed infrastructures such as HPC systems and cloud. In HPC environment the number of failures that can arise during scientific workflow enactment can be high so the use of fault tolerance techniques is unavoidable. The most frequently used fault tolerance techniques are job replication and checkpointing. While job replication is based on the assumption that the probability of single failures is much higher than of simultaneous failures, the checkpointing saves certain states and the execution can be restarted from that point later on. The effectiveness of the checkpointing method depends on the checkpointing interval. Common technique is to dynamically adapt the checkpointing interval. In this work we give a brief overview of the different checkpointing techniques and propose a new provenance based dynamic checkpointing method.
Follow the Profit or the Herd? Exploring Social Effects in Peer-to-Peer Lending

This paper examines the impacts of social factors on lenders’ decision-making in online peer-to-peer (P2P) lending. Data collected from a major U.S. online loan marketplace, Prosper.com, have been analyzed. We propose a model based on preferential attachment and fragmentation to model the bidding behavior of lenders. Our data analysis presents strong empirical evidence that there were significant herding effects when lenders made their investment decisions on loan listings. The distribution of the number of bids put on loan listings exhibits a power law with an exponential cutoff, which matches what the model predicts. The paper concludes that lenders on Prosper did not make rational investment decisions based on risk and returns, but followed the herd.
An integrated approach in the diagnosis of smoking-related interstitial lung diseases

Cigarette smoke consists of several chemical compounds with a variety of effects in many organs. In the lung, apart being the main cause of chronic obstructive pulmonary disease, carcinoma and idiopathic spontaneous pneumothorax, tobacco smoke is associated with interstitial lung diseases (ILDs), including respiratory bronchiolitis-associated ILD (RB-ILD), desquamative interstitial pneumonia (DIP), pulmonary Langerhans’ cell histiocytosis (PLCH), idiopathic pulmonary fibrosis, acute eosinophilic pneumonia, ILD in rheumatoid arthritis and pulmonary haemorrhage in Goodpasture syndrome. This review will focus on the diseases with a stronger epidemiological association with tobacco smoke, namely RB-ILD, DIP and PLCH. Although the exact pathogenetic evidence linking smoking with these disorders is still not completely understood, there is growing evidence that tobacco smoke targets the terminal or respiratory bronchioles in these diseases, and the differences are reflective of the degree of severity of small airway and parenchymal reaction to the smoke exposure. Despite considerable clinical, radiological and histological overlap between RB-ILD, DIP and PLCH, it is useful to retain the separate classifications for prognostic and therapeutic implications.
