HVAC technician would like wireless access points 5. The 23 new classrooms are not on the network 6. New wing has slow connections to the mail server 7. The IT Director would like to to integrate VoIP into the current data network 8. Backbone miss-cabled Solution The correction of the limited bandwidth is the first priority. Re-cabling the current network with Category 6 UTP 1000Base F Ethernet cabling because it increases maximum data rate, from 10 Mbps to 1 Gbps. Ethernet will also allow for the use of Carrier Sense Multiple Access with Collision Detection (CSMA/CD) which can be assigned on the workstation NIC. This bandwidth increase will resolve the HVAC Technicians access issue, congestion issues for the classrooms, allows for VoIP integration and provides for future expansion. Replacing the twisted-pair on the backbone with Fiber 1000Based-F will give continued Gigabit throughput and eliminate the remote mail server issue. The use of Fiber will eliminate the 120 distance issue also between the new and old wings and allow for further expansions.

...Introduction The purpose of this experiment is to figure out whether or not lying affects heart rate. There has been research conducted on the same problem in the past. In fact, polygraphs, more commonly known as lie detectors, have existed for quite some time. The idea for a polygraph was brought about by Cesare Lombroso in the year 1895. He was an Italian psychiatrist who believed he could use factors such as blood pressure, heart rate, and physical behaviors to determine whether or not the test subject was lying. However, back then his theory was quickly shoved to the side and dismissed along with his other theory of identifying criminals using the shape of their skull. At the beginning of the 1900’s a scientist by the name of William Marston decided to try and refine the design of the polygraph. Around the years of 1917 and 1923, William Marston had made a working lie detector. He stated that he could correctly deduce whether or not the subject was lying, with 95% accuracy (White 2001). To explain, the polygraph measures a person’s breathing rate, blood pressure, heart rate, and how much the subject is perspiring. The user asks a few simple questions to sort of calibrate the machine. For the most part, if one of the things that the machine is keeping track of spikes, that usually is a sign of lying. When a lie detector is used by somebody who is good at it, it can have a very high success rate. Although, the flaws are very visible in the lie detector, seeing as it doesn’t...

...Admissibility of Polygraph tests, Narco-anlaysis test and Brain-mapping test in reference to Selvi’s case Before answering these questions, it is necessary to examine the evolution and specific uses of the impugned techniques. Hence, a description of each of the test procedures is followed by an overview of their possible uses, both within and outside the criminal justice system. It is also necessary to gauge the limitations of these techniques. Polygraph Examination The origin of polygraph examination have been traced back to the efforts of Lombroso, a criminologist who experimented with a machine that measured blood pressure and pulse to assess the honesty of persons suspected of criminal conduct. His device was called a hydrosphygmograph. The theory behind polygraph tests is that when a subject is lying in response to a question, he/she will produce physiological responses that are different from those that arise in the normal course. During the polygraph examination, several instruments are attached to the subject for measuring and recording the physiological responses. The examiner then reads these results, analyzes them and proceeds to gauge the credibility of the subject's answers. Instruments such as cardiographs, pneumographs, cardio-cuffs and sensitive electrodes are used in the course of polygraph examinations. They measure changes in various aspects such as respiration, blood pressure, blood flow, pulse and galvanic skin resistance. There are three prominent...

...Now Business or Corporate users usually have an entire department dedicated to protecting them so they are less vulnerable. 2. What is the magnitude of the risk? That is, if security is compromised, what is the potential cost to the victim? Again this will depend on the user. Your average home users will run the risk of viruses, loss of data due to system crash and identity theft if they are not careful. With the Business or Corporate users the magnitude of the risk is much greater. If it is a financial institute, we could be talking millions of dollars at risk if security is compromised. 3. What policies and procedures can you suggest to counter the types of threats illustrated in this case study? * Intrusion Detection: A security service that monitors and analyzes system events for the purpose of finding and providing real-time or near-real-time warning of, attempts to access system resources in an unauthorized manner. * If an intrusion is detected quickly enough, the intruder can be identified and ejected from the system before any damage is done or any data compromised. * An effective IDS can serve as...

...Polygraphs as Truth or Lies Thanks to the abundance of police dramas on television, people have begun to believe that a polygraph test is infallible. Many studies, as well as a Supreme Court case, have since revealed that the veracity of polygraphs is far from impeccable. Also, there are few if any credible sources that support the veracity of polygraph machines. As Dr. Saxe and Israeli psychologist Gershon Ben-Shahar (1999) notes, "it may, in fact, be impossible to conduct a proper validity study." In real-world situations, it's very difficult to know what the truth is.” (American Psychological Association [APA], 2004) Polygraphs do not function as a lie detector. A polygraph only directly measures the autonomic responses of the subject. It measures reactions such as changes in skin conductance, pulse rate, blood pressure, and breathing while the subject is asked a series of questions. From that data, it makes an indirect assumption that positive physiological responsive indicate dishonesty and vice versa. When taking a polygraph test, proctors use several different tactics to elicit responses from their subjects. One is called the "relevant-irrelevant" technique, which mixes questions like "Did you steal the money?" in with questions like "Is today Tuesday?" Questions that are relevant to the topic are suppose to cause a jump within the subject’s autonomic system and in turn would produce results on the polygraph. Another tactic that is commonly used is "comparison questions"...

...“lie n: an untrue statement made with intent to deceive” The definition of the lie is something that is oft debated, and so there are many definitions that one could find. This paper will attempt to analyze one of these definitions in greater detail, specifically “lie n: an untrue statement made with intent to deceive” (1). To better understand the meaning of this definition it is important to break it up into the smaller parts from which its total meaning is gathered. These components are “an untrue statement” and “made with intent to deceive”. To comprehend the first half of the definition, “an untrue statement” it would be of value to solidly understand the words it contains. What then does untrue mean? And how is “untrue” differentiated...

...A polygraph records changes in respiration, electro dermal responses and cardiovascular activities (Elaad, 1998). Also known as a lie detector, which assess and records four major components that include heart rate, blood pressure, respiration and skin conductivity (Patrick, C. J., 1989). Electrolytes released on the skin surface during perspiration lowers the electrolytic resistance to the skin, thus increasing electro-dermal activity. Lying can cause changes in heart rate, breathing rate, and electro dermal activity. These responses can be stimulated by involuntary stress responses detecting in increase in the secreting of electrolytes or the increase sweat being secreted by sweat glands on the skin thus measuring the emotional connectivity and stress responses to the environment in respiration as well as the Detecting lies through a series of questions to maintain a common baseline, that will then be compared to other questions being asked, increase in heart rate or electro dermal activity is associated with telling a lie. The integumentary system consists of the skin which is considered the largest organ of the body and comprises 15 % of body weight. The integumentary serves to prevent water loss and the excess of water gain, resistance to trauma and infection, responsible to vitamin D syntheses, thermoregulation and sensation.

...In “no-talk” zone around the protected primary receiver, cognitive users must keep silent to allow the primary receiver to decode the received signal correctly. Since the quiet zone is outside the decodable region, cognitive devices are required to have high sensitivity in order to detect the primary signal in low SNR. Device-centric sensing methods mainly used in CR include energy detection, coherent detection, and cyclostationary feature detection [4]. The energy detector (radiometer) can detect any type of unknown primary signal. The coherent detector (matched filter) is the optimal detector for deterministic signal on Additive White Gaussian Noise (AWGN) channel, which can be used to detect the primary signals with a pilot. And the cyclostationary feature detector is suitable for the detection of non-white signal, such as the OFDM signal of DTV system [5]. Compared with other detectors, the performance of energy detector is lower. However, energy detector is most widely used because it doesn’t need any information about the primary signal, and has lower complexity to perform real-time detection. But energy detector totally can not detect the primary signal under a SNR threshold due to the impact of noise uncertainty. In [6], the existence of SNRwall is proved for all the moment detectors including energy detector. To reduce the noise uncertainty, some approaches were proposed, including...

...Cade Pendleton English 2010 Angie Carter June 14, 2012 Final Research Paper Man’s Best Friend: Dogs or Technology A few years ago I had the opportunity to job shadow a canine (k9) officer while he was participating in routine training with his dog. Little did I know, “routine training” meant all police canine officers in Salt Lake County, Utah County, and Davis County would assemble at an abandoned building and practice multiple real life scenarios. As I stood and watched in awe all night, I witnessed a few unsettling scenarios. First, I witnessed dog being released on command to attack a person acting as a criminal. The attack wasn’t the unsettling part about the scenario. What really bothered me was seeing the dog misidentify a fellow police officer as the criminal and attack the officer, who unfortunately was not in a bite suit. A bite suit is protective clothing the trainers wear when training their dogs to attack. Since the officer was not wearing protective gear, he suffered many lacerations and received multiple stiches. As the night continued, I was able to watch another training scenario involving Taser guns or stun guns. Unlike the dog, this technique worked flawlessly. The officer was able to take down the accurate perpetrator in a proficient manner and no fellow officers were injured. On this particular night, there was an accidental injury that doesn’t happen often involving the canine. However, this introduced a couple of questions. Does this happen frequently...
