Abnormal behavior detection for early warning of terrorist attack

Many terrorist attacks are accomplished by bringing explosive devices hidden in ordinary-looking objects to public places. In such case, it is almost impossible to distinguish a terrorist from ordinary people just from the isolated appearance. However, valuable clues might be discovered through analyzing a series of actions of the same person. Abnormal behaviors of object fetching, deposit, or exchange in public places might indicate potential attacks. Based on the widely equipped CCTV surveillance systems at the entrance of many public places, this paper proposes an algorithm to detect such abnormal behaviors for early warning of terrorist attack.

A comparison of Australian and Malaysian views on the use of biometric devices in everyday situations

Since the September 11, 2001 terrorist attacks in New York City, many countries including Australia and Malaysia have been able to justify the use biometric devices such as finger print scans, retina scans and facial recognition for identification and surveillance of its citizens and others in the name of national security. In addition, biometric devices are increasingly being used worldwide by organizations to keep track of their employees and their productivity, leading to concerns of privacy, the safety, reliability, abuse and misuse of the data collected and violations of civil liberties. Taking the critical theory perspective, this paper will analyse the data collected and report on the findings of a survey carried out in Australia and Malaysia, with respect to the responses provided and opinions expressed to the survey s open ended and other questions
by individuals as to their current use, experiences, preferences, concerns about the devices and the situations in which they think biometric devices should be used, including in their workplaces. This descriptive study uses both quantitative and qualitative data to examine what Australians and Malaysians think about the use of biometric devices in everyday situtions
and compare them as to their similarities and differences. The paper will then critically examine the ethical and civil liberties issues involved in the use of biometric devices in everyday life and argues that regulatory and legal measures should be taken to safeguard the rights of citizens while maintaining national security and productivity, in order to avoid the situation of Michel Foucaults Panopticon becoming an unpleasant everyday reality, which could negatively irifluence socialjustice and create social change due to its effects on individuals in two multicultural societies. The paper will argue about the need to educate the general public as to the issues of surveillance and privacy involved in the use of biometric devices in everyday situations.

A comparative analysis of opinions of Americans, Australians and Malaysians on the use of biometric devices in workplaces for security and monitoring of worker productivity

Since the September 11, 2001 terrorist attacks in New York, the use of biometric devices such as fingerprint scans, retina and iris scans and facial recognition in everyday situations for national security and border control, have become commonplace. This has resulted in the biometric industry moving from being a niche technology to one that is ubiquitous. As a result. more and more employers are using biometrics to secure staff access to their facilities as well as for tracking staff work hours, maintaining 'discipline' and carry out surveillance against thefts. detecting work hour abuses and fraud. However, the data thus collected and the technologies themselves are feared of having the potential for and actually being misused - both in terms of the violating staff privacy and discrimination and oppression of targeted workers. This paper examines the issue of using biometric devices in organisational settings their advantages, disadvantages and actual and potential abuses from the point of view of critical theory. From the perspectives of Panoptic surveillance and hegemonic organisational control, the paper examines the issues related to privacy and identification, biometrics and privacy, biometrics and the 'body', and surveillance and modernity. The paper also examines the findings ofa survey carried out in Australia. Malaysia and the USA on respondents' opinions on the use of biometric devices in everyday life including at workplaces. The paper concludes that along with their applications in border control and national security, the use of biometric devices should be covered by relevant laws and regulations. guidelines and codes of practice. in order to balance the rights to privacy and civil liberties of workers with employers' need for improved productivity, reduced costs, safeguards related to occupational health and safety, equal opportunity, and workplace harassment of staff and other matters, that employers are legally responsible for.

Insulin delivery devices

Everyone with type 1 diabetes requires insulin from diagnosis and more than 30% of people with type 2 diabetes eventually need insulin because of progressive failure of pancreatic beta cells. People with type 2 diabetes are often reluctant to commence insulin and some will require assistance with their injections. Over the past five years a number of new insulin delivery systems have become available that can make insulin administration easier. A number of factors, including patient preference, influence the choice of device. A thorough assessment of the individual's self-care capacity is important and appropriate education is imperative when starting insulin.

A preliminary examination of public opinion in Australia on the use of biometric devices or identifiers in everyday life

Since the September 11,2001 terrorist attacks in New York City, many countries including Australia have been able to justify the use of biometric devices for identification and surveillance of their own citizens and others in the name of national security.

This paper reports on the preliminary findings of a survey that examined Australians' views and experiences with the use of biometric devices in everyday situations in the context of their potential to serve as a 'Panopticon' to keep the nation's citizenry under surveillance. It discusses the adoption of the new communication technology from the point of view of the Justification model that sees technology choice as social
gambling and the pluralist view of technology that sees technology as neutral in itself but as having negative or positive effects on society based on how It is used.

The paper proposes the need for Australian society to balance citizens' right to privacy and civil liberties with the right to stay alive and safe from terrorism and how it may be done with the necessary legal and regulator)' safeguards.

Location based power control for mobile devices in a cellular network

This paper provides location estimation based power control strategy for cellular radio systems via a location based interference management scheme. Our approach considers the carrier-to-interference as dependent on the transmitter and receiver separation distance and therefore an accurate estimation of the precise locations can provide the power critical mobile user to control the transition power accordingly. In this fully
distributed algorithms, we propose using a Robust Extended Kalman Filter (REKF) to derive an estimate of the mobile user’s closest mobile base station from the user’s location, heading and altitude. Our analysis demonstrates that this algorithm can successfully track the mobile users with less system complexity, as it requires measurements from only one or two closest mobile base stations and hence enable the user to transmit at the rate that is sufficient for the interference management. Our power control
algorithms based on this estimation converges to the desired power trajectory. Further, the technique is robust against system uncertainties caused by the inherent deterministic nature of the mobility model. Through simulation, we show the accuracy of our prediction algorithm and the simplicity of its implementation.

Evaluation of nasopharyngeal oxygen, nasal prongs and facemask oxygen therapy devices in adult patients: a randomised crossover trial

Nasopharyngeal oxygen (NPO) therapy may overcome some of the difficulties associated with nasal prongs and facemask oxygen delivery devices. In response to a lack of published studies of NPO therapy in adults, we conducted a prospective randomised crossover trial to compare the effectiveness of NPO, nasal prongs (NP) and facemasks (FM) when used in an adult population (n=37) from the intensive care unit and general hospital wards. We measured oxygen saturation (Sp[O.sub.2]) using pulse oximetry, oxygen flow (litres per minute), respiration rate (per minute) and comfort using a horizontal visual analogue scale. All three devices were effective in maintaining a Sp[O.sub.2] of [greater than or equal to]95% (NP 97.0[+ or -]1.9, NPO 97.7[+ or -]1.7, FM 98.8[+ or -]1.3%). NPO therapy consumed less oxygen than NP and FM therapy (NP 2.6[+ or -]1.0, NPO 2.2[+ or -]0.9, FM 6.1[+ or -]0.4 l/min, P <0.001). There was no significant difference in patients' respiratory rates (NP 19.9[+ or -]3.2, NPO 19.9[+ or -]3.0, FM 19.8[+ or -]3.1 per minute, P=0.491). In terms of comfort, patients rated NP higher than NPO and FM using a horizontal visual analogue scale (100 mm=most comfortable) (NP 65.5[+ or -]14.3, NPO 62.8[+ or -]19.4, FM 49.4[+ or -]21.4 mm, P <0.001). We conclude that for adult patients, nasal prongs and nasopharyngeal oxygen therapy consume less oxygen and provide greater comfort than facemasks while still maintaining Sp[O.sub.2] [greater than or equal to]95%.
