Some issues in privacy data management
A method and apparatus is provided for aligning and press-fitting connector terminals into a substrate. The terminals are initially supported together by a bandolier strip, and an alignment tool aligns the terminals with apertures in the substrate to which the terminals will be press-fitted. A pressing tool engages the shanks of the terminals to fold the bandolier away from the terminals and thereafter press the terminals into the apertures.

Management of Conflicting Obligations in Self-Protecting Policy-Based Systems
Policy-based management of business systems is increasingly becoming the norm for autonomic computing since these systems can adapt to the changing needs and increasing complexity of the underlying organizations or enterprises. One of the vital characteristics of these systems is self-protection, ie., the ability to secure information and resources, by anticipating, detecting, identifying and protecting against any form of unauthorised access and permitting all authorised accesses based on the users' roles and pre-established policies. In this paper, we focus on one aspect of self-protecting autonomous systems, which is, how to automatically enforce privacy policies related to data handling, for compliance and auditing purposes. The automatic management of privacy sensitive information based on enterprise policies that are driven by a combination of user preferences, internal objectives and external regulations is a key aspect to any enterprise to prevent misuse of this information. These policies extend beyond simple authorization rules, and also mandate obligations to be enforced under certain conditions. One issue in the automatic enforcement of obligations is the presence of conflicts among different obligations which mandate different actions on the same resource, based on different conditions in which the resource is accessed. In this paper we propose algorithms for detecting and resolving conflicts among obligations in both static and runtime environments. We then briefly describe our prototype obligation management system with the conflict resolution module that achieves the automated enforcement of obligations for data-handling based on privacy policies

Towards Automated Privacy Compliance in the Information Life Cycle
Management of data is an increasingly challenging task for enterprises because of the increasingly diverse and complex requirements that come to bear from various fronts. One issue is the protection of the privacy of the information held, while ensuring compliance with various rules and regulations relating to data management.One issue is the protection of the privacy of the information held, while ensuring compliance with various rules and regulations relating to data management. Privacy may be defined as the claim of individuals, groups and institutions to determine for themselves when, how and to what extent information about them is communicated to others. In its broadest scope this is a problem that has challenged civil rights advocates the world over, at different times.

Web Page Ranking Based on Events
Search results of web search engines are displayed according to their ranking function, which is a function of the in-links and the out-links of the web page. Users are generally overwhelmed by the thousands of results retrieved by the search engine, few of which are useful. Most of the search engine users are interested in the latest information about the searched keywords. Such pages containing the latest information about an event (or incident) are not always ranked high by the search engines due to the lack of sufficient in-links pointing to these web pages. For example, if a search query “DaWaK” is given to Google, the users are generally interested in the latest information i.e., the home page of DaWaK 2004 conference, which is not ranked in the top 10 results returned by Google. In this paper we address the problem of ranking the web pages based on events (or incidents) related to the searched keywords. We provide a method for finding patterns that constitute events in the search results returned by a conventional search engine and then rank the web pages based on these event patterns. We also describe a mechanism whereby our technique can be used inside the ranking function of a conventional search engine such as Google. We provide experimental results that validate the efficiency and use of our technique in capturing the user intentions.

Towards bringing database management task in the realm of IT non-experts
Internet enabled services have led to an increase in the size and complexity of the database making the database administration task very complex. This necessitates the hiring of skilled personnel for the management of data, which is a bane for industries, especially in developing countries. We at IBM India research Lab, have been developing technologies (i.e. database administration tools), wherein the database administrator, who may be inexperienced person, can define error-free policies for managing and maintaining the distributed information repositories, and can define data access privileges to users at fine as well as at coarse-grained level using natural language like constructs. These policies represent the actions that need to be carried out when specific database/temporal events occur within the system or externally and are notified to the system. In this paper, we discuss the architecture of our policy based database administration and access control system and outline some of the technical challenges in this area.

Research issues in real-time DBMS in the context of electronic commerce
In future, information products in electronic commerce setting will be subjected to the sazae quality/service standards found in traditional industries. Furthermore, each user views quality such as on-time delivery, correctness, and completeness differently and values information differently. In order to recognize customized requirements, real-time databases are required in electronic commerce. Since an economic paradigm is implicit in electronic commerce, we need to integrate economic issues into managing real-time databases. An appropriate priority pricing mechanism can potentially increase collective benefits and simplify database functions such as deadline assignment, admission control, scheduling, buffer management, and data management. We discuss these emerging issues and provide an information services

Global models with parametric offsets as applied to cardiac motion recovery
We introduce a new solid shape model formulation that includes built-in offsets from a base global component (e.g. an ellipsoid) which are functions of the global component's parameters. The offsets provide two features. First, they help to form an expected model shape which facilitates appropriate model data correspondences. Second, they scale with the base global model to maintain the expected shape even in the presence of large global deformations. We apply this model formulation to the recovery of 3-D cardiac motion from a volunteer dataset of tagged-MR images. The model instance is a variation of the hybrid volumetric ventriculoid (HVV), a deformable thick-walled ellipsoid model resembling the left ventricle (LV) of the heart. A unique aspect of of implementation is the employment of constant volume constraints when recovering the cardiac motion. In addition, we present a novel geodesic-like prismoidal tessellation of the model which provides for more stable fits.

The use of hybrid models to recover cardiac wall motion in tagged MR images
We present a new algorithm for the automatic recovery of tag grid-line intersections in Tagged MR images of the left ventricle of the heart. Our method uses an active spring mesh to capture local properties of the motion and a global motion model to capture the global coherence of the motion. We recover the global component of the motion using robust estimation. Different motion models have been developed for short and long axis views of the heart. The algorithm has been tested on healthy and pathological data.

Performance Indicators in a 802.11 WLAN Deployment
Organizations and Institutions across the world are increasingly deploying 802.11 based WLAN (in short Wi-Fi) to have mobility benefits in their operations. However, due to the nature of 802.11 technology, there are more number of challenges for an administrator in ensuring the optimum performance levels for the deployed WLAN compared to a Wired Network. Degraded performance leads to connectivity problems and low data throughput for wireless clients using the Wi-Fi network. In the presented work, we have identified a set of indicators whose values at any point of time signals a possible degradation in WLAN performance. Each of the identified indicators is explained and the behavior of same is illustrated using an example with respect to presence or absence of performance anomalies in a WLAN deployment.
