A Session Initiation Protocol User Agent with Key Escrow

Voice over Internet Protocol (VoIP), also called IP telephony is rapidly becoming a familiar term and as a technology it is invading the enterprise, private usage, and educational and government organizations. Exploiting advanced voice coding & compression techniques and bandwidth sharing over packet switched networks, VoIP can dramatically improve bandwidth efficiency. Moreover enhanced security features, mobility support, and cost reduction features of VoIP are making it a popular choice for personal communication. Due to its rapid growth in popularity VoIP is rapidly becoming the next generation phone system. Lawful interception is a mean of monitoring private communication of users that are suspected of criminal activities or to be a threat to national security. However, government regulatory bodies and law enforcement agencies are becoming conscious of the difficulty of lawful interception of public communication due to the mobilitysupport and advanced security features implemented in some implementations of VoIP technology. There has been continuous pressure from the government upon the operators and vendors to find a solution that would make lawful interception feasible and successful. Key escrow was proposed as a solution by the U. S. National Security Agency. In key escrow the key(s) for a session are entrusted to a trusted third party and upon proper authorization law enforcement agencies can receive the session key(s) from this trusted third party However, key escrow adds some security vulnerabilities and potential risks as an unethical employee of the key escrow agent (or a law enforcement agency that has received the session key(s)) can misuse the key(s) to forge content of a communication session -- as he or she possesses the same key(s) as the user used for this session. This thesis addresses the issue of forged session content, by proposing, implementing, and evaluating a cryptographic model which allows key escrow session content. The implementation utilizes an existing implementation of a Session Initiation Protocol (SIP) user agent ‘minisip’ developed at KTH. The performance evaluation results suggest that the proposed model can support key escrow while protecting the user communication from being forged with the cost of minimal computational resource and negligible overhead. without the possibility of undetectable fabrication of session content.

A Stochastic Structure Model for Predicting Sheet Consolidation and Print Uniformity

The microscopic response of a paper sheet to compressive forces is of great importance in predicting print quality as well as the sheet structures developed in wet pressing and calendering. In this report, we propose a new compression model that preserves the entire three-dimensional, stochastic, fibre network structure. The model includes Z-directional deformation of fibres in both compressive and shear modes. Permanent deformation of each fibre (such as caused by fibre collapse) can be achieved by adjusting the stiffness of the fibre during compression or unloading. The stiffness of the plates can also be chosen to represent, for example, a hard printing plate, a blanket, or a soft-nip calendar cover. Although we still need to collect basic fibre stiffness data in order to perform quantitative comparisons between model predictions and experimental results, simulated structures already show typical features of consolidated paper sheets. As a first application, we study the contact mechanics between a printing plate and a model paper structure.
Model based estimation of the complex material constants for thickness extension and radial mode in an ultrasound disk transducer

The main goal of this thesis is to establish a method and estimate the complex material constants for the radial and thickness mode. This has been done in two separate methods. For the thickness mode material constants, a optimization script in MATLAB has been developed, which is capable of directly optimizing all the input parameters for the xTrans, for both active and passive layers. The method has been evaluated, and the complex material constants describe behavior in accordance with measured data. For estimating the radial mode complex material constants, an evaluation a publish method by S.Sherrit has been done.
Results of the CoreOrganic-Workshop on animal based parameters in Trenthorst, Germany (04.02.08-08.02.2008)

It was the aim of this meeting to train the assessors of several CoreOrganic-Partners (i.e. Austria, Germany, Denmark and Norway) with regard to the methods which are going to be applied in the course of the project on-farm assessments. Training involved animal-based parameters, a resource checklist and a management questionnaire. After a theoretical and practical introduction, inter-observer reliability (IOR) of the main animal-based parameters was tested. This included gait scoring/lameness, body condition, cleanliness and integument alterations. The scoring systems for gait scoring, cleanliness and integument alterations had been adapted from the WelfareQuality® protocol; body condition was scored according to Metzner et al. (1993). Subjective scoring systems which are used in many epidemiological studies have the advantage that they do not require any equipment but - due to the subjectivity of the assessment - it is necessary to achieve acceptable inter-observer reliability (IOR) before and after the study to ensure valid data.
The Partner Track: A Novel

In the eyes of her corporate law firm, Ingrid Yung is a "two-fer. " As a Chinese-American woman about to be ushered into the elite rank of partner, she's the face of Parsons Valentine & Hunt LLP's recruiting brochures - their treasured "Golden Girl. " But behind the firm's welcoming facade lies the scotch-sipping, cigar-smoking old-boy network that shuts out lawyers like Ingrid. To compensate, Ingrid gamely plays in the softball league, schmoozes in the corporate cafeteria, and puts in the billable hours - until a horrifically offensive performance at the law firm's annual summer outing throws the carefully constructed image way out of equilibrium. Scrambling to do damage control, Parsons Valentine announces a new "Diversity Initiative" and commands a reluctant Ingrid to spearhead the effort, taking her priority away from the enormous deal that was to be the final step in securing partnership. For the first time, Ingrid finds herself at odds with her colleagues - including her handsome, golden-boy boyfriend - in a clash of class, race, and sexual politics.
CALIBRATION OF INCIDENT DETECTION ALGORITHMS FOR OPERATIONAL USE

Techniques to reduce the impact of incidents on freeways have been widely implemented by operational freeway agencies. In this article, the techniques of detection, and more specifically on automatic detection through a system of embedded loops, associated detectors, communications and a data processing subsystem are described. Development of the data processing portion of such a system, the incident detection algorithms has been ongoing in the USA since the early 1970's. The seminal work by the Federal Highway Administration is described in IRRD 225375 and 225376. This project produced a set of new algorithms for processing freeway surveillance data to yield indications of the presence of incidents in the freeway traffic stream. Subsequently, a subset of these algorithms were implemented in the Semi-Automated Traffic Management System (SATMS) as a part of the operational freeway surveillance system in Los Angeles. However, the potential of these algorithms was not immediately realized in practice, because the necessary calibrations to determine zone-specific parameters of the algorithms for the zones of the Los Angeles freeways which are under surveillance had not yet been done. This paper describes the ongoing activities of a current research project, the purpose of which has been to determine the appropriate zone-specific parameters. A review is made of the issues entailed in incident detection and a description of the SATMS in Los Angeles and general issues in calibration of incident detection algorithms highlighted. Then the technical approach taken to calibration in the operational environment of SATMS where over 800 zones are involved, and an array of anomalous conditions exist is described. The effort of calibration is ongoing. Interim results are presented here, and representative problems are described. In conclusion an indication of the planned course for the remainder of the calibration effort, is given. For the covering abstract of the conference see IRRD 832076.

HEALTH IMPROVEMENT ACTIVITIES IN PRESCHOOL DAILY ROUTINE

Aim. The aim of this article is to develop and justify a complex of physical education and health improvement activities, including swimming, for 4–5-year-old children. Materials and methods. The study was conducted on the premises of “A” and “B” preschool establishments in Chelyabinsk. 44 boys and girls aged 4–5 years participated in the study. Children from kindergarten “A” were involved in swimming with a complex of additional health improvement activities, including sauna, phytotherapy, and cold exposure training. During the study, the following methods have been used: the analysis and synthesis of special and methodical literature, pedagogical observations, pedagogical experiment, control tests for swimming skills assessment, calculation methods, mathematical statistics. Results. The application of the complex proposed (sauna, cold exposure training, phytotherapy) in the experimental group decreased significantly children’s disease frequency by the end of the course. This proves a positive influence of the complex proposed on immunity in 4–5-year-old children in preschool establishments. Conclusion. Methodical peculiarities of a health improvement program influenced the level of children’s swimming skills. The analysis of disease frequency during a year allows us to suppose that the complex proposed influenced positively body resistance to unfavorable environmental conditions
Development of a Comprehensive Modal Emissions Model

In August 1995, the College of Engineering-Center for Environmental Research and Technology (CE-CERT) at the University of California-Riverside along with researchers from the University of Michigan and Lawrence Berkeley National Laboratory, began a four-year research project to develop a Comprehensive Modal Emissions Model (CMEM), sponsored by the National Cooperative Highway Research Program (NCHRP, Project 25-11). The overall objective of the research project was to develop and verify a modal emissions model that accurately reflects Light-Duty Vehicle (LDV, i.e., cars and small trucks) emissions produced as a function of the vehicle's operating mode. The model is comprehensive in the sense that it is able to predict emissions for a wide variety of LDVs in various states of condition (e.g., properly functioning, deteriorated, malfunctioning). The model is now complete and capable of predicting second-by-second tailpipe emissions and fuel consumption for a wide range of vehicle/technology categories. In creating CMEM, over 350 vehicles were extensively tested on a chassis dynamometer, where second-by-second measurements were made of both engine-out and tailpipe emissions of carbon monoxide, hydrocarbons, oxides of nitrogen, and carbon dioxide. CMEM itself runs on a personal computer or on a UNIX workstation. The model and the emissions database are both available on a CD.
Novel Microsystem Techniques for Liquid Manipulation and Pressure Sensing

Scaling down operations and functions into the fascinating micro world not only improve performance, lower costs, and enable easier integration, but also opens the door to new functionalities. This truly multidisciplinary thesis presents novel solutions to current and relevant challenges in the areas of 1) on-chip liquid manipulation which has applications in micro total analysis systems, medical diagnostics, and drug discovery and 2) pressure sensing which has an established market in the automotive and industrial processes industry. Especially in the area of liquid manipulation, the aim was to take advantage of forces and properties dominating on the micro scale whenever possible, rather than compensating for these effects, and to create solutions with universal appeal and application areas. In the area of liquid manipulation, this thesis discusses a novel method of passively synchronizing liquid movement on-chip based on liquid surface tension and device geometry. This technique has potential applications in timing independent processes, liquid-liquid interactions, and digitizing liquid movement. A fast and passive discrete sample micromixer is also presented based on the same principles. A unique way of direct access, bubble tolerant sample interfacing with flow-through microfluidics using a closed-open-closed channel is also introduced. This method can be used to regulate flow on-chip without the need for any moving parts or electrical contact. Moreover, work is presented on two types of out-of-plane electrospray ionization mass spectrometry (ESI-MS) emitter tips which mimic ideal mass spectrometry tips. Fabrication of these tips is uncomplicated and results in robust structures with good performance. In the field of pressure sensing, this thesis investigates a form based resonating principle. The Q factor of the sensor is improved by low pressure encapsulation and structure design. A novel technique for excitation and detection of resonant microsensors using 'burst' technology is also demonstrated. This method involves temporally separating excitation and detection, thereby eliminating crosstalk and the need for electrical feedthroughs. It also allows high voltages to be used with sensitive circuitry and a single electrode to be used for both excitation and detection.
Distributed traffic signal control using fuzzy logic

We present a distributed approach to traffic signal control, where the signal timing parameters at a given intersection are adjusted as functions of the local traffic condition and of the signal timing parameters at adjacent intersections. Thus, the signal timing parameters evolve dynamically using only local information to improve traffic flow. This distributed approach provides for a fault-tolerant, highly responsive traffic management system. The signal timing at an intersection is defined by three parameters: cycle time, phase split, and offset. We use fuzzy decision rules to adjust these three parameters based only on local information. The amount of change in the timing parameters during each cycle is limited to a small fraction of the current parameters to ensure smooth transition. We show the effectiveness of this method through simulation of the traffic flow in a network of controlled intersections.
Capacity building: home and away

Many countries are at pivotal points for reforming their education systems, particularly Asian countries moving into English as the medium instruction. The Ministry of Education Malaysia aims to reach its government’s Vision 2020 for education reform, which includes teaching science education in English. Achieving Vision 2020 requires capacity building for Malaysian teaching institutes and their lecturers. The capacity building in this study involved professional development on specific preservice teacher education units conducted through Australian and English universities. Thirty-one Malaysian lecturers from two institutes were involved in professional development with three Australian university lecturers associated with a new primary science education degree. In addition, 96 Malaysian preservice teachers were co-taught by both the Malaysian and Australian lecturers over a two-week period, which provided lecture and tutorial demonstrations on science education, English, and human development psychology. This paper highlights capacity building in the areas of teaching and learning for Malaysian teaching institutes and the affiliated Australian university. Malaysian and Australian lecturers and the Malaysian preservice teachers gained an opportunity to refine their pedagogical knowledge and content knowledge with linkages to current theories (i.e. on science education, English, and human development psychology). International collaboration appeared to enhance teaching and learning programs by globalizing coursework, and presented potential for collaborative research.

Gemeinsame Stellungnahme der Chirurgischen Arbeitsgemeinschaft Coloproktologie (CACP) der Deutschen Gesellschaft für Allgemein- und Viszeralchirurgie (DGAV) und der AG Gastrointestinal- und Abdominaldiagnostik der Deutschen Röntgengesellschaft (DRG) zur Standardisierung der präoperativen Ausbreitung

Über viele Jahre galt die neoadjuvante Radiochemotherapie (oder Kurzzeit-Radiotherapie) mit anschließender operativer Resektion als Standardtherapie für Rektumkarzinome des unteren und mittleren Rektumdrittels in den UICC-Stadien II und III (cT3/4 und/oder cN+). In den letzten Jahren erfolgt eine zunehmend differenzierte Anpassung der Therapieoptionen auf Basis der Tumorinfiltrationstiefe in das mesorektale Fettgewebe, des Tumorabstandes zur mesorektalen Faszie (MRF) sowie des LK-Befalls. So eröffnet die aktuelle S3-Leitlinie die Option einer Therapiedeeskalation. Bei Tumoren mit geringer Infiltrationstiefe (frühes T3 bzw. T3a/b) und fehlendem LK-Befall kann auf eine vorangehende Strahlentherapie verzichtet und primär operiert werden. In der OCUM-Studie [1] war das Vorgehen einer alleinigen Operation mit risikoadaptierter adjuvanter Chemotherapie auf Basis einer exakten Beschreibung des Abstandes des Tumors zur mesorektalen Faszie (MRF) in vielen Fällen möglich [1]. Weitere Studien (RAPIDO, PRODIGE und OPRA) adressieren wiederum die Intensivierung der adjuvanten Therapie als sog. „totale neoadjuvante
