Abstract
This paper explains that, since 9/11, countries with a high level of terrorism, such as Israel, use metal detectors, which were formerly used mainly in prisons, but are now used in airports and other public buildings. The author reports that there are three types of metal detectors in general use today, including walk-through, hand-held, and extended arm types. The paper relates that several newer technologies, such as back-scatter X-ray, millimeter wave analysis, and terahertz wave technology, are in various phases of development and deployment to supplement the basic equipment that has traditionally relied on magnetic induction fields and their interaction with electrically conductive and magnetically permeable materials.

From the Paper
"Most metal detectors utilize an electromagnetic field generated by passing an electric current through a wire coil. In the case of walk-through metal detectors, the electromagnetic field is projected in the form of a wall between the borders formed by the equipment; hand-held devices project a circular field surrounding the length of the device. In the case of walk through detectors, subjects (and any potential targets) pass completely through the electromagnetic field, whereas hand-held devices are employed by passing them close enough to potential targets to come within the known dimensions of the magnetic field surrounding the device. Extended arm detectors function exactly the same as hand-held devices, except that their design allows them to be more easily deployed to bring their electromagnetic field closer to the ground for their specific use in detecting buried weapons or contraband."

Abstract
This study develops reliable data that fire safety and security management professionals can use in the development of models for smoke detector types and placement in high-bay hangar facilities. Two research questions are investigated in this paper and hypotheses are tested in relation to each research question. The research questions investigated were as follows:
1. What effect does bay height have on smoke detector sensitivity in a high-bay hangar?
2. What effect does the use of a draft curtain have on smoke detector sensitivity in a high-bay hangar?

Each of the hypotheses is supported by the analysis of the data. The results of the research performed for this study show that, as bay height increases (all other factors remaining equal), smoke detector sensitivity decreases. The results of the research performed for this study further show that smoke detector sensitivity is higher when draft curtains are in place than when draft curtains are not in place.
Based on these findings, the paper concludes that the use of draft curtains should be mandated in all high-bay hangars. It concludes, further, that means should be found to deploy smoke detectors at levels lower than ceiling height in bays higher than 15 meters.

From the Paper
"A total of 33 full-scale fire experiments were conducted in two high-bay hangars. The two high-bay hangars were of different heights, thereby allowing the effects of height on smoke detector sensitivity to be measured and assessed. Draft curtains were used in some experiments but not in others. This approach allowed the effects of the use of draft curtains on smoke detector sensitivity to be measured and assessed. Varying fire sizes were used in the experiments."

Abstract
Over the past ten years, many technology companies have succumbed to the economic conditions that have dictated their demise. InVision Technologies is a company that has risen to the occasion and silenced many of the pessimists and naysayers. This paper identifies InVision's strategic strengths and weaknesses based on an environmental "scan" analysis. The discussion also focuses on the core competencies of the organization and develops a Porter's "Five Forces" analysis for the organization. Finally, it discusses the strategic thinking of company CEO, Sergio Magistri.

From the Paper
"Another strength that the company has is diversification. Diversification allows the company to spread out its profits over different industries, so that all of the company's eggs are not in one basket. The company operates in the security industry and the timber industry. InVision has found innovative ways to harvest timber and detect weapons and explosives. (Company Profile 2003) This innovation has guided the company to the top of the field and the company has virtually no competition in the field of explosives detections systems."

From the Paper
"Introduction
Employee theft and dishonesty is estimated to cost companies and other employers as much as $220 billion per year (Jayne 47); because of this, employers have become increasingly concerned about the background of the people they hire, and the likelihood that individuals will steal from the company, engage in corporate espionage, or file false lawsuits against the company in order to reach a settlement. While the pre-employment interview can help uncover important information, including information about an applicant's qualifications for a job and how well the person might fit into the organization, it is difficult to determine whether a particular individual is honest during a 30 minute interview, or whether they are likely to engage in behavior which is harmful to the organization. As advances have been made in science and technology..."

Abstract
This paper examines how, in the United States, the accidental affliction of death caused by fires and burns occupies the fourth place. It attempts to show how smoke alarms are the chiefly efficient, initial cautioning device existing for the home and how they give precious time to run away from a fire. Generally, fires can propagate quickly through a home, and people may have as little as two minutes to run away following the alarm sounds. The possibility of dying in a housing fire is reduced to half when a functioning smoke alarm is available.

From the Paper
"Though heat detectors are put into use for residential purposes from 1921, "the field tests have shown that they are not as efficient as smoke detectors in sensing fires in the home" and the Section 16, Chapter 3 of the NFPA Fire Protection Handbook asserts that genuine fire tests in suburban occupancies have shown that considerable amounts of smoke have come before the considerable amounts of heat in approximately all cases. Most of the residential fires belong to the slow burning flame type and the most important point is that they are not of the soaring heat building type. (Smoke Detectors in the Home: A Matter of Life & Death) Most of the serious home fire happens when the people are fast asleep at night. Reports show that most people die due to smoke and poisonous gases rather than the fire itself. Many people at night do not know that there was a fire."

Abstract
A discussion of how the Edinburgh postnatal depression scale (EPDS) has proven to be an excelent and adaptabe detector of postpartum depression.

From the Paper
"Postpartum depression is dark cloud that hangs over the joy of having a child. It can lead to a lower quality of life, family troubles, delayed infant development, (Small, et al.) and even death by suicide. Because of its physical component, however, it responds very well to treatment. The greatest challenge in fighting this illness is detection and diagnosis. The Edinburgh Postnatal Depression Scale (EPDS) offers great hope in identifying those who are suffering from postpartum depression worldwide so that they may receive treatment. Depression has been called..."

Abstract
This paper explains that increased technology guarantees time-efficiency and improves the mode of action against crime, thus, decreasing the risk to which a police official in the field might otherwise be exposed. The author points out that DNA testing is gathering increased support from lawmakers because there is no longer any reason to question the reliability of DNA evidence. The paper reports that a concealed weapon detector, such as "Millivision", measures the electromagnetic radiation emitted by all objects made out of plastic, metal, liquid or ceramics, analyses it and converts the readings into a visible form thus providing better surveillance capabilities including anti-terror.

Conclusion

From the Paper
"In 1996, the U.S. Justice Department had given the D.C. police a $6 million grant to complete installation of computers in police cruisers and enable officers to process criminals at each of the city's seven police districts. It is seen that police all over the United States is being equipped with more computers in their patrol cars. In 2000, Lisle Police was allocated $85,700 in the budget draft, to be used for squad cars equipped with radar and data computers."

Abstract
This is a technical work where the author discusses new, cutting edge technologies and their possible application for interplanetary communication. Specifically, the author refers to broadband communications technologies and the recent development of nanowire technology that enables the construction of microscopically thin cables, which, because of their extreme sensitivity and the great distance of interplanetary space, hold great potential for the development of new communication devices and technologies.

From the Paper
"The design of the MIT photo-detector is relatively simple from an engineering standpoint (see Appendix for diagram of the photo-detector). This is especially true considering the high degree of efficiency it is capable of producing. Of course, the simplicity of the design belies the significant calibration the device requires: the nanowire must be cooled to almost absolute zero, the glass gap of the photon trap must be a very specific function of the wavelength of incoming photons, and the use of an anti-reflective coating on the surface of the device is critical. The design consists of a photon trap with a nanowire detector followed by a gap of glass, and then a mirrored surface. The nanowire is wrapped in a tight coil in order to maximize its absorption of incoming photons, and the nanowire is cooled to close to absolute zero, three degree Kelvin to be precise, which transforms the nanowire into a very small superconductor. As a superconductor, the nanowire responds in specific ways to photons that impact the nanowire allowing for detection."

Abstract
This paper describes some of the new police technologies. It focuses on three different categories: two mature technologies -- MDT and MCT; two newly-implemented technologies GIS/GPS mapping technology and NASA's VISAR technology; and finally, two emerging technologies that are still in technological and policy development stages, but have been already tested to prove their effectiveness in police work: PMI technology and Thermal Imaging Lie Detector Technology.

From the Paper
"Gas chromatography is a method for the separation and analysis of complex mixtures of volatile organic and inorganic compounds (1:666). Most compounds with boiling points less than 250oC (480oF) can be analyzed using this technique. This paper will describe the apparatus used for gas chromatography, the principles on which it works, how a thermal conductivity detector works in gas chromatography, and whether or not it can be used with a sample of potassium t-butoxide.


General Principles of Gas Chromatography
There are two types of gas chromatography: gas-liquid chromatography, where the sorbent is a nonvolatile liquid called the stationary liquid phase, coated as a thin layer on an inert, granular solid support; and gas-solid chromatography, where the sorbent is a granular solid of large surface area (1:666).
