Geovisualization Approaches for Spatio-temporal Crime Scene Analysis --- Towards 4D Crime Mapping
Authors: Markus Wolff, Hartmut Asche
Venue: Proceedings of the 3rd International Workshop on Computational Forensics (2009)

This paper presents a set of methods and techniques for analysis and multidimensional visualisation of crime scenes in a German city. As a first step the approach implies spatio-temporal analysis of crime scenes. Against this background a GIS-based application is developed that facilitates discovering initial trends in spatio-temporal crime scene distributions even for a GIS untrained user. Based on these results further spatio-temporal analysis is conducted to detect variations of certain hotspots in space and time. In a next step these findings of crime scene analysis are integrated into a geovirtual environment. Behind this background the concept of the space-time cube is adopted to allow for visual analysis of repeat burglary victimisation. Since these procedures require incorporating temporal elements into virtual 3D environments, basic methods for 4D crime scene visualisation are outlined in this paper.

The experiments can provide support for preservation and administration of relics and provide information for teaching and learning activities of cultural studies.
View-Invariant Action Recognition from Point Triplets
Authors: Yuping Shen, Hassan Foroosh
Venue: IEEE Transactions on Pattern Analysis and Machine Intelligence (2009)

We propose a new view-invariant measure for action recognition. For this purpose, we introduce the idea that the motion of an articulated body can be decomposed into rigid motions of planes defined by triplets of body points. Using the fact that the homography induced by the motion of a triplet of body points in two identical pose transitions reduces to the special case of a homology, we use the equality of two of its eigenvalues as a measure of the similarity of the pose transitions between two subjects, observed by different perspective cameras and from different viewpoints. Experimental results show that our method can accurately identify human pose transitions and actions even when they include dynamic timeline maps, and are obtained from totally different viewpoints with different unknown camera parameters.

Data@Risk: Building an Asset Mindset Towards Securing Data
Authors: David Stelzl
Venue:  (2009)

How Secure are your Digital Assets? Why are so many companies losing data despite the increases in security spending? Why aren't the latest advancements in technology keeping hackers out? Whether you're a CEO, a line of business manager, or work in Information Technology watching over a company's core systems, you create and use digital assets. In most companies, these assets form some of the most important elements of your organization and require special treatment. In this book you'll learn what it means to be: Asset Focused: What does it mean to be asset focused rather than technology focused? See how cyberthieves have developed one of the most lucrative businesses our economy has seen by understanding the value of digital assets. Restrictive with Access: Who should have access to what? How can companies ensure that the right people have the proper levels of access to the information they need, while still maintaining a posture of security? Read how easy it is to gain access to data through departmental users who are just doing their job. Digitally Aware: How do digital assets differ from physical assets? How can managers and end-users approach data in a more secure fashion, while still being able to perform their job functions? Read about government officials who lost their jobs because they weren't aware of digital assets under their watch. Alert verses Lockdown: How can companies balance the need for access with requirements for security? See how a bank's approach to data security changed when they applied the same concepts they use to secure their physical branches. Ready to Respond: Most security fails. So how can companies ensure that their data will not be siphoned off over several months or years, as seen in numerous reports over the past five years? See how my own family met intruders with an effective response plan; one you can't afford not to have. Always Assessing: Most companies I speak with don't see any immediate security problems. What should companies be looking for? Read about a pharmaceutical company that unknowingly exposed over 17,000 employee records over peer to peer networks, and how to prevent this from happening to you. Holistic: How do companies move away from silos of security products to an effective strategy for securing data? Read how your own home security can provide a simple roadmap to effective corporate security. Data@Risk will teach you an asset mindset that will secure your company data against modern attacks.

Compact models of human reaching motions for robotic control in everyday manipulation tasks
Authors: Freek Stulp, Ingo Kresse, Alexis Maldonado, Federico Ruiz, Andreas Fedrizzi, Michael Beetz
Venue: Proceedings of the 2009 IEEE 8th International Conference on Development and Learning (2009)

Autonomous personal robots are currently being equipped with hands and arms that have kinematic redundancy similar to those of humans. Humans exploit the redundancy in their motor system by optimizing secondary criteria. Tasks which are executed repeatedly lead to movements that are highly optimized over time, which leads to stereotypical [25] and pre-planned [15] motion patterns. This stereotypical motion can be modeled well with compact models, as has been shown for locomotion [1]. In this paper, we determine compact models for human reaching and obstacle avoidance in everyday manipulation tasks, and port these models to an articulated robot. We acquire compact models by analyzing human reaching data acquired with a magnetic motion tracker with dimensionality reduction and clustering methods. The stereotypical reaching trajectories so acquired are used to train a Dynamic Movement Primitive [12], which is executed on the robot. This enables the robot not only to follow these trajectories accurately, but also uses the compact model to predict and execute further human trajectories.
Using Distributed Processing to Create More Powerful, Flexible and User Matched Accessibility Services
Authors: Gregg C. Vanderheiden
Venue: Proceedings of the 5th International on ConferenceUniversal Access in Human-Computer Interaction. Part II: Intelligent and Ubiquitous Interaction Environments (2009)

Accessibility today is characterized by individual devices, which have been custom-built for people with disabilities (talking alarm clock, braille watches, special communication devices, etc.) or mainstream devices such as computers, which have been adapted with hardware or software to be usable by an individual with disabilities. This model results in more isolated access packages whose capabilities are limited by the particular devices on which they are run. By moving to more distributed, network-based accessibility solutions, we open up the potential for a much wider range of accessibility solutions which can not only evolve over time, but vary by environment, task, etc. A rainbow of on-demand services and capabilities can be available to them. It also opens up the potential for individuals who cannot afford assistive technologies to be able to tap into a pool of free public assistive services that they can use on any device which they encounter.

Research on the Innovative Examination Method of Vertical Tank Capacity
Authors: Shizhong Tong, Zhi Xie, Changhai Li, Weiwei Yin, Junjie Ma, Guizeng Fu
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 03 (2009)

The measuring accuracy factors of the influence vertical tank are briefly introduced in this text. Wall-climbing robot measurement is used to measure the radical deviation during the computation of the vertical tank, and the putting-into-type liquid level meter is used to measure the increment of the tank’s bottom for the first time. By these two ways, this design realizes the relevant examination system. These two methods can overcome shortages of traditional methods, increasing the precision of the vertical tank.
Hellinger Strikes Back: A Note on the Multi-party Information Complexity of AND
Authors: T. S. Jayram
Venue: Proceedings of the 12th International Workshop and 13th International Workshop on Approximation, Randomization, and Combinatorial Optimization. Algorithms and Techniques (2009)

The ${\textsc{And}}$ problem on t bits is a promise decision problem where either at most one bit of the input is set to 1 (No instance) or all t bits are set to 1 (${\textsc{Yes}}$ instance). In this note, I will give a new proof of an ¿(1/t) lower bound on the information complexity of ${\textsc{And}}$ in the number-in-hand model of communication. This was recently established by Gronemeier, STACS 2009. The proof exploits the information geometry of communication protocols via Hellinger distance in a novel manner and avoids the analytic approach inherent in previous work. As previously known, this bound implies an ¿(n/t) lower bound on the communication complexity of multiparty disjointness and consequently a ¿(n 1 ¿ 2/k ) space lower bound on estimating the k-th frequency moment F k .
Discriminative learning of selectional preference from unlabeled text
Authors: Shane Bergsma, Dekang Lin, Randy Goebel
Venue: Proceedings of the Conference on Empirical Methods in Natural Language Processing (2008)

We present a discriminative method for learning selectional preferences from unlabeled text. Positive examples are taken from observed predicate-argument pairs, while negatives are constructed from unobserved combinations. We train a Support Vector Machine classifier to distinguish the positive from the negative instances. We show how to partition the examples for efficient training with 57 thousand features and 6.5 million training instances. The model outperforms other recent approaches, achieving excellent correlation with human plausibility judgments. Compared to Mutual Information, it identifies 66% more verb-object pairs in unseen text, and resolves 37% more pronouns correctly in a pronoun resolution experiment.
Review: Personalizing recommendations for tourists
Authors: Katerina Kabassi
Venue: Telematics and Informatics (2010)

Internet has significantly influenced the tourism sector providing a great variety of services and products online. However, the number of choices has increased so dramatically that is very difficult for the consumers to find what they are looking for. For this purpose, recommendation systems for tourism have attracted a lot of research energy and interest. The main characteristic of these systems is that they can personalize their recommendations to each user interacting with the system. Personalization is even more essential for tourism recommendation systems used in handheld devices where the screen is even smaller and the presentation capabilities are limited. This paper addresses these problems and provides some development steps for a tourism recommendation system by making a state of the art in personalized e-tourism services both in computers and handheld devices as well as a review of the user modeling and personalization techniques used in these systems. Furthermore, the theories used for the improvement of the personalization procedure in tourism recommendation systems; their applications and evaluation are discussed.
Motion Synthesis Using Style-Editable Inverse Kinematics
Authors: Gengdai Liu, Zhigeng Pan, Ling Li
Venue: Proceedings of the 9th International Conference on Intelligent Virtual Agents (2009)

In this paper, a new low-dimensional motion model that can parameterize human motion style is presented. Based on this model, a human motion synthesis approach by using constrainted optimization in a low-dimensional space is proposed. We define a new inverse kinematics solver in this low-dimensional space to generate the required motions meeting user-defined space constraints at key-frames. Our approach can also allow users to edit motion style explicitly by specifying the style parameter. The experimental results demonstrate the effectiveness of this approach which can be used for interactive motion editing.
Types for Secure Pattern Matching with Local Knowledge in Universal Concurrent Constraint Programming
Authors: Thomas Hildebrandt, Hugo A. López
Venue: Proceedings of the 25th International Conference on Logic Programming (2009)

The fundamental primitives of Concurrent Constraint Programming (CCP), ${\mathit{tell}}$ and ${\mathit {ask}}$, respectively adds knowledge to and infers knowledge from a shared constraint store. These features, and the elegant use of the constraint system to represent the abilities of attackers, make concurrent constraint programming and timed CCP (tcc) interesting candidates for modeling and reasoning about security protocols. However, they lack primitives for the communication of secrets (or local names as in the ¿-calculus) between agents. The recently proposed ${\mathit{universal}} {\mathtt{tcc}}$ (utcc) introduces a universally quantified ask operation that makes it possible to infer knowledge which is local to other agents. However, it allows agents to guess knowledge even if it is encrypted or communicated on secret channels, simply by quantifying over both the encryption key (or channel) and the message simultaneously. We present a secure utcc (utcc s ) based on: (i) a simple type system for constraints allowing to distinguish between restricted (secure) and non-restricted (universally quantifiable) variables in constraints, and (ii) a generalization of the universally quantified ask operation to allow the assumption of local knowledge. We illustrate the use of the utcc s calculus with examples on communication of local names (as in the ¿-calculus) and for giving semantics to secure pattern matching in a prototypical security language.
Spatio-temporal Tone Mapping Operator Based on a Retina Model
Authors: Alexandre Benoit, David Alleysson, Jeanny Herault, Patrick Callet
Venue: Computational Color Imaging: Second International Workshop, CCIW 2009, Saint-Etienne, France, March 26-27, 2009. Revised Selected Papers (2009)

From moonlight to bright sun shine, real world visual scenes contain a very wide range of luminance; they are said to be High Dynamic Range (HDR). Our visual system is well adapted to explore and analyze such a variable visual content. It is now possible to acquire such HDR contents with digital cameras; however it is not possible to render them all on standard displays, which have only Low Dynamic Range (LDR) capabilities. This rendering usually generates bad exposure or loss of information. It is necessary to develop locally adaptive Tone Mapping Operators (TMO) to compress a HDR content to a LDR one and keep as much information as possible. The human retina is known to perform such a task to overcome the limited range of values which can be coded by neurons. The purpose of this paper is to present a TMO inspired from the retina properties. The presented biological model allows reliable dynamic range compression with natural color constancy properties. Moreover, its non-separable spatio-temporal filter enhances HDR video content processing with an added temporal constancy.

Adaptation versus Retrieval Trade-Off Revisited: An Analysis of Boundary Conditions
Authors: Stephen Lee-Urban, Héctor Muñoz-Avila
Venue: Proceedings of the 8th International Conference on Case-Based Reasoning: Case-Based Reasoning Research and Development (2009)

In this paper we revisit the trade-off between adaptation and retrieval effort traditionally held as a principle in case-based reasoning. This principle states that the time needed for adaptation reduces with the time spent searching for an adequate case to be retrieved. In particular, if very little time is spent in retrieval, the adaptation effort will be high. Correspondingly, if the retrieval effort is high, the adaption effort is low. We analyzed this principle in two boundary conditions: (1) when very bad and (2) when highly capable adaptation procedures are used. We conclude that in the first boundary condition the adaptation-retrieval trade-off does not necessarily exist. We also claim that the second does not hold for a class of planning domains frequently used in the literature. To validate this claim, we performed experiments on two domains of this type.

A Restructuring Method for WS-BPEL Business Processes Based on Extended Workflow Graphs
Authors: Thomas S. Heinze, Wolfram Amme, Simon Moser
Venue: Proceedings of the 7th International Conference on Business Process Management (2009)

Much research effort has been spent on the provision of analysis methods for business processes specified by means of Web Services Business Process Execution Language (WS-BPEL). Nevertheless, most approaches neglect conditional control flow, though running the risk of erroneous analysis results. In this paper, we present a restructuring approach for WS-BPEL processes, which helps to partly remedy conditional control flow. We therefore use a combination of workflow graphs and Concurrent Static Single Assignment Form. Based on the hybrid format, we are able to identify loops with static quasi-constant loop condition and transform them in such a way, that conditional control flow is replaced by unconditional control flow. Augmenting an existing analysis with the proposed restructuring then enables more precise results, as is shown for a compatibility analysis of WS-BPEL business processes.
Standards going concrete: from LMF to Morphalou
Authors: Laurent Romary, Susanne Salmon-Alt, Gil Francopoulo
Venue: Proceedings of the Workshop on Enhancing and Using Electronic Dictionaries (2004)

Lexical resources are key components for applications related to human language technology. Various models of lexical resources have been designed and implemented during the last twenty years and the scientific community has now gained enough experience to design a common standard at an international level. This paper thus describes the ongoing activity within ISO/TC 37/SC 4 on LMF (Lexical Markup Framework) and shows how it can be concretely implemented for the design of an on-line morphological resource for French in the Morphalou project.
