Explosive detection

Brunetta and Guastalla (2000) gave a concept of free flight after their study on traffic network congestion which results in the ground holding policies that are quotient, on the other hand, Hormann (2001) focused on the cultural, organizational and behavioral elements of the aviation safety crew. In other research and examinations, Mathews and Kauzlarich (2000) centred on the ValuJet Flight 592 crash and performed a case study on the airline; Changa & Yang (2011) in their study were concerned with the passengers’ perception of cabin safety in relation to the experiences they encountered during an emergency evacuation. In their “Explosives Detection Systems (EDS) For Aviation Security,Signal Processing” study, Singh, S. and Singh, M. (2002) highlighted some of the critical technologies that need to be integrated into the system for explosive detection and the use of computer-aided machines which will ease is in the analysis data received by security equipment. From the literature reviewed, it can be summed that the aviation sector is a dynamic industry and researchers work around the clock to establish an efficient system that will enhance aviation safety. Research Question The primary objective to be addressed in this article is the examination of the existing relationship between human error, safety endorsements and competencies required to enhance aviation safety. It can be argued that human error is a hard topical hence the question; to what extent is an action…

For the past 6 million years, some form of beings have been on the Earth. Throughout time, many things have changed, and those forms of beings have evolved into humans. One thing has remained the same over the years - the idea that in order to live functionally with each other, we need to tell the truth. However, not everyone chooses to do so. Luckily, technology has advanced enough for us to change that. The polygraph is one way to sight a lie. In 1921, medical student John Augustus Larson…

Relevant information on the examinee and the facts about the case surrounding the examination are gathered and studied and action plans are created before the actual testing is conducted. Once completed, the actual lie detection examination can start. Lie Detector Testing is subdivided into three different stages: The Pre-Exam Interview; The Polygraph Exam; and The Post-Exam Interview. This is typically administered by a professionally trained and certified polygraph examiner or polygraphist…

Lies are being told all around us. Of 555 character traits evaluated, lying was categorized as the worst, yet research also shows that people lie daily and don’t feel significant guilt for their deception (DePaulo, Kashy, Kirkendol, Wyer & Epstein, 1996). With the great prevalence of dishonesty in most social interactions, much research has been focused on aspects of lying and effective methods of lie-detection. Studies have deduced the three main aspects of lying to be verbal, nonverbal, and…

A micro expression is a tiny facial cue that appears within one-fifth of a second. It is uncontrollable and shows an observer signs of every emotion. It shows signs of deceit as well. Usually these are undetectable, but with some training they can be detected and used in investigations. Therefore, facial micro-expressions should be admissible in federal investigations. We need a replacement for polygraphs, and micro-expressions are a fine candidate. The previously used lie detector, the…

The basic definition of a lie is to state something on purpose to a group of people, or even a person, that is false. In order for a person to lie about something that person will need a reason, either to cover something up, to explain something in a nicer way in order not to make the specific person being lied too to feel bad, to hid information that is thought of un important or un necessary, or even to just get out of a situation. There are multiple types of lies, to many to state actually;…

Whenever the word nitro comes up it turns to something explosive. In chapter 5 it is mainly about nitro compounds and it explains what is and how it works based on the molecular structure. Nitro compounds are indeed explosive. Gun powder can be considered one of the earliest items to be referred as a fire chemical component. The gun powder components are known to be all reactive products which cause the reaction of an explosion. Nitro compounds are highly reactant and is stabled by a molecule…

For instance, many paradigms in lie detection studies include memory confounds, which make it difficult to isolate the brain processes specific to deception. Farah et al. (2014, p. 125) cite a study by Gamer et al. as an example of this, in that Gamer et al. found showing participants pictures they had previously memorized resulted in activation in the same brain areas that are often implicated in studies of deception. Satel and Lilienfeld (2013, p. 79) cite an additional memory confound in that…

concentration of Triton-X to be 0.05%, so 1 mL of 0.5% was added to the final 10 mL matrix. Dr. Doolittle’s handout suggested that the optimal dithizone concentration was 50 μM in 10 mL, so 0.5 mL of 1μM dithizone was added to the matrix. 1 mL of solution was added to the matrix, along with 3 mL of water. In previous trials, 0.5 mL of buffer was added to solution (and water was added appropriately to get to 10 mL); however, this was later modified (see table below), as it was crucial to main a…

technology that could potentially grow into a huge part of our legal system and even now it is moving forward at a rapid pace and continuing to develop. We have made various discoveries and we have created ways to not only make our lives much easier but also to create reliable detections that could serve us in the courtroom. However, many argue that these advance technologies may not be as reliable as we would hope, which raises a big concern…
