Neural correlates of stereotype application
Authors: Jason P. Mitchell, Daniel L. Ames, Adrianna C. Jenkins, Mahzarin R. Banaji
Venue: Journal of Cognitive Neuroscience (2009)

Recent research has focused on the disparate mechanisms that support the human ability to "mentalize" about the thoughts and feelings of others. One such process may rely on precompiled, semantic beliefs about the characteristics common to members of a social group, that is, on stereotypes; for example, judging that a woman may be more likely than a man to have certain interests or opinions. In the current study, we identified a pattern of neural activity associated with the use of stereotypes to judge another person's psychological characteristics. During fMRI scanning, participants mentalized about the likely responses of a female and male target to a series of questions, some of which were related to gender stereotypes (e.g., "enjoys shopping for new clothes"). Trials on which participants applied a stereotype were segregated from those on which participants avoided stereotype use. The BOLD response in an extensive region of the right frontal cortex differentiated stereotype-applied from -unapplied trials. Moreover, this neural difference was correlated with a behavioral index of gender associations-the Implicit Association Test-administered after scanning. Results suggest that stereotype application may draw on cognitive processes that more generally subserve semantic knowledge about categories.

The main goal of this paper is to study the finite groups whose lattices of fuzzy subgroups are distributive. We obtain a characterization of these groups which is similar to a well-known result of group theory.
New results on delay-dependent robust stability criteria of uncertain fuzzy systems with state and input delays
Authors: Li Li, Xiaodong Liu
Venue: Information Sciences: an International Journal (2009)

This paper focuses on the delay-dependent stability analysis and stabilization for uncertain T-S fuzzy control systems with state and input delays. The key features of the approach include the introduction of uncorrelated augmented matrix items into the Lyapunov functional and the use of a tighter bounding technology. In fact, these techniques lead to more general and less conservative stability conditions that guarantee a wide stability region. Our delay-dependent stability conditions thus obtained are given in terms of linear matrix inequalities (LMIs). Finally, some examples are included to show that the proposed criteria improve the existing results significantly.
Speaker-independent phoneme alignment using transition-dependent states
Authors: John-Paul Hosom
Venue: Speech Communication (2009)

Determining the location of phonemes is important to a number of speech applications, including training of automatic speech recognition systems, building text-to-speech systems, and research on human speech processing. Agreement of humans on the location of phonemes is, on average, 93.78% within 20ms on a variety of corpora, and 93.49% within 20ms on the TIMIT corpus. We describe a baseline forced-alignment system and a proposed system with several modifications to this baseline. Modifications include the addition of energy-based features to the standard cepstral feature set, the use of probabilities of a state transition given an observation, and the computation of probabilities of distinctive phonetic features instead of phoneme-level probabilities. Performance of the baseline system on the test partition of the TIMIT corpus is 91.48% within 20ms, and performance of the proposed system on this corpus is 93.36% within 20ms. The results of the proposed system are a 22% relative reduction in error over the baseline system, and a 14% reduction in error over results from a non-HMM alignment system. This result of 93.36% agreement is the best known reported result on the TIMIT corpus.

Authors: Jing Li, Xiao-dong Mu, Ling Shi, Bin Xiong
Venue: Proceedings of the 2009 International Conference on Advanced Computer Control (2009)

Grey theory has been applied widely in the field of prediction and decision, but model precision is influenced extremely by sequence smooth degree, boundary value and background value. Particle swarm has well effect in searching for best result because it is an efficient way. The paper advances a new method, improved particle swarm is used to optimize the boundary value and background value of GM(1,1) model, and sin function is used to deal with sequence. It has been shown that the improved model is better through predicting the lifetime of mechanical products.
The complexity of an individual program
Authors: John L. McTap
Venue: Proceedings of the May 19-22, 1980, national computer conference (1980)

Zolnowski and Simmons proposed an interesting measure of program complexity. But it suffers from four major practical defects: a) It cannot be applied to an individual program without first identifying a group of existing programs as a reference base. b) It does not provide a reliable measure since the measure usually changes each time the composition of the group of programs changes. c) It is burdensome to compute because the computation must be for an entire group of programs to make possible measuring the complexity of an individual program. d) It cannot be applied to the components within a program, such as modules or subroutines.
A dependence graph-based representation for test coverage analysis of object-oriented programs
Authors: ESF Najumudheen, Rajib Mall, Debasis Samanta
Venue: ACM SIGSOFT Software Engineering Notes (2009)

Test coverage analysis is used to determine the extent to which different features of interest are exercised by a given test suite. For object-oriented programs, it involves determining the extent to which features such as inheritance, polymorphism, dynamic binding, etc. are exercised. As object-oriented coverage analysis using only source code or object code is difficult and inefficient, the source code is converted to a suitable intermediate representation for subsequent analysis. We propose a dependence graph-based representation for object-oriented programs, named Call-based Object-Oriented System Dependence Graph (COSDG). COSDG captures the important object-oriented features, provides details of method visibility in a derived class, and differentiates various calling contexts with different type of method call edges: simple, inherited, and polymorphic. We also propose an algorithm to construct COSDG incrementally. Though COSDG has been developed primarily to aid test coverage analysis, it can be used in a variety of other software engineering applications also.
Concurrent performance of military and robotics tasks and effects of cueing in a simulated multi-tasking environment
Authors: Jessie Y. C Chen
Venue: Presence: Teleoperators and Virtual Environments (2009)

We simulated a military mounted crewstation environment and conducted two experiments to examine the workload and performance of the combined position of gunner and robotics operator. The robotics tasks involved managing a semi-autonomous ground robot or teleoperating a ground robot to conduct reconnaissance tasks. We also evaluated whether aided target recognition (AiTR) capabilities (delivered either through tactile or tactile + visual cueing) for the gunnery task might benefit the concurrent robotics and communication tasks. Results showed that participants' gunnery task performance degraded significantly when they had to concurrently monitor, manage, or teleoperate an unmanned ground vehicle compared to the gunnery-single task condition. When there was AiTR to assist them with their gunnery task, operators' concurrent performance of robotics and communication tasks improved significantly. However, there was a tendency for participants to over-rely on automation when task load was heavy, and performance degradations were observed in instances where automation failed to be entirely reliable. Participants' spatial ability was found to be a reliable predictor of robotics task performance, although the performance gap between those with higher and lower spatial ability appeared to be narrower when the AiTR was available to assist the gunnery task. Participants' perceived workload increased consistently as the concurrent task conditions became more challenging and when their gunnery task was unassisted. Individual difference factors such as spatial ability and perceived attentional control were found to correlate significantly with some of the performance measures. Implications for military personnel selection were discussed.
A study on gigabit laser driver circuit with RC shunt circuit for LD current waveform correction
Authors: Takahiro Emoto, Shinsuke Konaka, Masatake Akutagawa, Yohsuke Kinouchi
Venue: Proceedings of the 2008 International Conference on Advanced Infocomm Technology (2008)

Bipolar laser driver IC circuits in 2.5 gigabits/s optical transmitters for the access network systems have been studied to reduce the overshoots in the laser diode current waveforms by optimizing a RC shunt circuit connected to the laser diode in parallel by using a SPICE circuit simulator. The laser diode current is overshot by a parasitic inductance of the bonding wire between the bipolar IC chip and the DFB laser diode chip, when the current is modulated at over gigabits/s. In this paper, the optimum conditions are described on the R and C values of the shunt circuit. The idea controlling the C value of the RC shunt circuit by an external voltage supply is proposed to compensate the C value deviation from the optimum value to minimize the overshoot. And it is also described that the variable capacitor using a PN diode made of a base-collector connected bipolar transistor has effectively reduced the overshoots caused by the wire inductance increase.
Design & Development of a GSM Based Vehicle Theft Control System
Authors: B. G. Nagaraja, Ravi Rayappa, M. Mahesh, Chandrasekhar M. Patil, T. C. Manjunath
Venue: Proceedings of the 2009 International Conference on Advanced Computer Control (2009)

This paper deals with the design & development of a theft control system for an automobile, which is being used to prevent/control the theft of a vehicle. The developed system makes use of an embedded system based on GSM technology. The designed & developed system is installed in the vehicle. An interfacing mobile is also connected to the microcontroller, which is in turn, connected to the engine. Once, the vehicle is being stolen, the information is being used by the vehicle owner for further processing. The information is passed onto the central processing insurance system, where by sitting at a remote place, a particular number is dialed by them to the interfacing mobile that is with the hardware kit which is installed in the vehicle. By reading the signals received by the mobile, one can control the ignition of the engine; say to lock it or to stop the engine immediately. Again it will come to the normal condition only after entering a secured password. The owner of the vehicle & the central processing system will know this secured password. The main concept in this design is introducing the mobile communications into the embedded system. The designed unit is very simple & low cost. The entire designed unit is on a single chip. When the vehicle is stolen, owner of vehicle may inform to the central processing system, then they will stop the vehicle by just giving a ring to that secret number and with the help of SIM tracking knows the location of vehicle and informs to the local police or stops it from further movement.
Using bimodal kernel for inference in nonparametric regression with correlated errors
Authors: Tae Yoon Kim, Byeong U. Park, Myung Sang Moon, Chiho Kim
Venue: Journal of Multivariate Analysis (2009)

For nonparametric regression model with fixed design, it is well known that obtaining a correct bandwidth is difficult when errors are correlated. Various methods of bandwidth selection have been proposed, but their successful implementation critically depends on a tuning procedure which requires accurate information about error correlation. Unfortunately, such information is usually hard to obtain since errors are not observable. In this article a new bandwidth selector based on the use of a bimodal kernel is proposed and investigated. It is shown that the new bandwidth selector is quite useful for the tuning procedures of various other methods. Furthermore, the proposed bandwidth selector itself proves to be quite effective when the errors are severely correlated.

Authors: Maowen Wang, Yejun He, Guangxi Zhu, Deming Liu
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 01 (2009)

This paper firstly proposed some considerations for cable-fed network and dipole design of TD-SCDMA smart antennas. Secondly, we constructed an eight-element linear antenna array. In this antenna array, electronic tuning down tilt angle is set as zero degree. Half-wave dipole, cable-fed network as well as fiber reinforced plastics radome are used. The proposed model is simulated by Ansoft HFSS software. Simulation results show that this dipole can obtain better bandwidth and radiation specifications. Combined-dipole antenna array is also consistent with standard of TD-SCDMA smart antenna.
Linking Leadership And Technical Execution In Unprecedented Systems-Of-Systems Acquisitions
Authors: Frank J. Sisti, Dewitt T. Latimer IV
Venue: Journal of Integrated Design Process Science (2007)

The acquisition of systems is as much an art as a science, a premise that is underscored by the limited understanding of the variables found in complex systems-of-systems. Moreover, the art and science associated with acquiring systems has been steadily increasing in complexity as the various technologies being acquired have made huge advances in capabilities. One of the most challenging types of acquisition to execute well is that requiring the development of an unprecedented systemof- systems or an ultra large scale system. The challenges to the acquisition staff range the spectrum of those faced at all levels in the acquiring organization. Multiple challenges exist from the most senior leadership and management, through those architecting the system, down to the individual engineer executing technical tasks as a part of the concept, design, development, fielding, and sustainment of such systems-of-systems. Leadership theory based on transformational and transactional leadership styles assists in highlighting leadership problems in unprecedented acquisitions. Coupled to these challenges are the clearly demonstrable requirements for ever closer linkages between each of the discrete functional levels within the acquiring organization. The study of the essential nature of theses linkages, and how their performance can severely impact the probability of success and effectiveness of the acquisition, is examined through the evaluation of a number of exemplar case studies. Using analytical insight derived from these case studies, combined with the application of current theories on leadership and management, this paper evolves the transdisciplinary premise by articulating that leadership and technical execution must be tightly linked especially when developing unprecedented systems-of-systems.
jLab: Integrating a scripting interpreter with Java technology for flexible and efficient scientific computation
Authors: Stergios Papadimitriou, Konstantinos Terzidis
Venue: Computer Languages, Systems and Structures (2009)

The jLab environment extends the potential of Java for scientific computing. It provides a Matlab/Scilab like scripting language that is executed by an interpreter implemented in the Java language. The scripting language supports the basic programming constructs with Matlab like matrix manipulation operators. The jLab ''core'' provides the general purpose functionality with an extensive set of built in mathematical routines that cover all the basic numerical analysis tasks. Application specific functionality can be dynamically ''plugged'' in jLab by means of toolboxes. These toolboxes can be easily implemented in Java. They are packaged in .jar files for convenient handling and their corresponding classes can be dynamically integrated to the system. The important advantage of jLab compared to other similar environments is the potentiality to dynamically and automatically integrate Java code to the system in order to obtain both execution speed and to reduce the programming effort. This task is supported both by an easy to use extension Java class wizard and by application specific class wizards that automate the utilization of jLab's scientific libraries. Numerical analysis algorithms can require enormous computation resources and at the same time an expressive programming environment. We demonstrate the potentiality of jLab by describing the implementation of a simple numerical analysis algorithm that detects the zero of a function. Also an additional example concerning the solution of ODEs with the compute intensive Runge-Kutta methods is illustrated. The former task can be facilitated with the external class wizard while the ODE wizard can completely automate the later.
Exploring websites through contextual facets
Authors: Yevgeniy Medynskiy, Mira Dontcheva, Steven M. Drucker
Venue: Proceedings of the 27th international conference on Human factors in computing systems (2009)

We present contextual facets, a novel user interface technique for navigating websites that publish large collections of semi-structured data. Contextual facets extend traditional faceted navigation techniques by transforming webpage elements into user interface components for filtering and retrieving related webpages. To investigate users' reactions to contextual facets, we built FacetPatch, a web browser that automatically generates contextual facet interfaces. As the user browses the web, FacetPatch automatically extracts semi-structured data from collections of webpages and overlays contextual facets on top of the current page. Participants in an exploratory user evaluation of FacetPatch were enthusiastic about contextual facets and often preferred them to an existing, familiar faceted navigation interface. We discuss how we improved the design of contextual facets and FacetPatch based on the results of this study.

Algebraic model and communication tool of a language
Authors: Cristina I. Brumar, Iulian Pah, Emil M. Popa, Laura F. Cacovean
Venue: Proceedings of the 12th WSEAS international conference on Computers (2008)

In this paper we try to manage two concepts of language. The first defines the algebraic model of language, considerate like a tuple: L = <Sem, Syn, L: Sem → Syn>. The second concept of language is regarded as a communication tool that allows language users to develop knowledge, while interacting with their universe of discourse, and to communicate with each other, while exchanging knowledge. The results presented here have as initial point [1], [7].
A new procedure model for verification and validation in production and logistics simulation
Authors: Markus Rabe, Sven Spieckermann, Sigrid Wenzel
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

Verification & Validation of simulation models and results has been strongly investigated in the context of defence applications. Significantly less substantial work can be found for applications for production and logistics, which is surprising when taking into account the massive impact that wrong or inadequate simulation results can have on strategic and investment-related decisions for large production and logistics systems. The authors have, therefore, founded an expert group for this specific topic in the year 2003, which has analysed the existing material and then developed proposals for definitions, overviews on existing V&V techniques, practical hints for the documentation of the procedural steps within a simulation study, and a specific procedure model for V&V in the context of simulation for production and logistics. The results of this working group are available as a textbook, in German. This paper summarises major results.
