Extract of sample "Change Detection"

Download file to see previous pages There was allocation of independent variable of the detail level on the target of change and spatial distribution of attention, in this experiment (Hornsby et al, 2009).
The subject of this experiment was to carryout change detection tests to determine whether an observer would notice the changes that occurred before his/her eyes. Most people do not notice all the changes which occur before their eyes. This is not because they are blind but due to reasons such as poor or lack of attention required to notice such changes. In order to detecting the changes require much attention and visual simulation.
The experimental purpose is to determining the abilities of different observers to notice the changes that occur before their eyes. The dependent variables in the change detection experiment were: visual attention to the dynamic region and the internal mechanism attained by specific visual codes for detailed
The experiment was carried out with limitations to observation as a method of detecting changes which occurred around an observer or before his/her eyes. Change blindness method was used to elaborate how visual memory is limited to currently features attended to. The use of mechanisms that provide a central perception to the world made the change detection experiment important (Styles, 2006)
The flicker paradigm was used in the Change detection Cog lab experiment, in order to demonstrate the influence of attention and working memory in change detection (Van Horn et al., 2011). The presence or absence of a flicker between images was the independent variable while accuracy and response time in milliseconds were the dependent variables (Van Horn et al., 2011). The participant sample consisted of 32,789 global participants, including 49 undergraduate students enrolled in Memory and Cognition courses at Houston University, Texas (VanHorn et al., 2011). ...Download file to see next pagesRead More

Anomaly Detection Methodologies

...?Anomaly Detection Methodologies Introduction Medical records of patients contain thousands or millions of electronic entries that record informationon patient’s conditions, diagnosis and treatments. Tisdale (2010) says that while the storage and use of this data has been helpful in providing a detailed profile of individual patients, the benefits of using this information in identifying the most adverse cases are relatively unexplored and underutilized. Besides, current practices and procedures aimed at identifying such patients are slow, expensive and unsuitable for incorporating new analytical mechanisms. Buckeridge (2007) argues that Current algorithms used for achieving this risk stratification are dependent on the labelling... of the...

Detection of Fabry disease

...Detection of Fabry disease Principle of multiplex-PCR technology: Multiplex Polymerase chain reaction (Multiplex-PCR) is a PCR technique in which more than one target sequence can be amplified simultaneously by incorporating more than one pair of primers in the same reaction. This process amplifies genomic DNA using multiple primer pairs where each primer pair targets a single locus. When multiple genes are targeted at the same time, much information can be obtained from a single test run. This is a modification of PCR technology which uses multiple primers and temperature-mediated DNA polymerase in a thermal cycler. This technique can amplify two or more separate DNA regions. Multiplex PCR can be the end point of an...

Land mine detection

...?Land Mine Detection by HOW DOES THE UNDERGROUND LOCATION OF LANDMINES COMPLICATE DETECTION? 1.1 Problems with the Structure of Mines Mines are hard to detect because they come in various shapes and types of casings, therefore “[an efficient] detection system should be either insensitive to the…shape of the mine and the type of casing material” (Hussein & Waller 1999). If the detection system is sensitive to the shape of the mine, then it will falsely detect objects underground which possess the same shape as mines but may actually be rocks or shreds of metal. Similarly, if the detection system is sensitive to the type of...

Breaker Failure Detection Algorithms

...the numerical BF protection. Introduction Contingency analysis remains to be one of the great tasks that face protection engineers. The reason to this is due to the fact that a Protection Engineer has to focus on Murphy’s Law and Ohms Law concurrently. The design for PRS plays a key role in detecting any fault that happens on the power system and the possibilities of eruption of any fault in the protection system of the power system. When the protective relay system is order, the designers of the power system understand it but the condition changes when a failure is detected. Deriving solutions towards this failure is what makes a protection engineer proficient. The protection engineer...

Intrusion Detection System

... to be detected by the engine. When a large amount of data enters into a system, they are fragmented into smaller parts. Fragmentation helps in easy flow of data over the network. Before it enters the detection engine, it has to be fragmented. Preprocessor defragments all the parts and brings it as a complete packet. (Garside 2007). Hackers change the URI which look the same as a normal web server. Preprocessors detect these attacks and decode the URI. In some situation it has the additional work of re-assembling the streams. Detection Engine The work of detection engine is to identify the intrusive activity in the packet that is sent by the preprocessor. This is achieved by the rules. Internal structures are fed with the rules... Intrusion...

Network Intrusion Detection Systems

...Network Intrusion Detection systems Introduction Network Intrusion Detection systems are widely used andthey are one of the major component in a network. These systems help to prevent the intrusion and attacks by using a unique mechanism. Intrusion detection system detects and protects the network system from threats and attacks. It is the most important component of the network system. It is mandatory for the network systems to install an intrusion detection system to easily manage the attacks and resolve the issues. (Mun 2009). There are various types of intrusion systems and they are implemented based on the network system. These intrusion systems...

Intrusion Detection

...that differ on several axes. A few of these axes comprise: (Silberschatz, Galvin, & Gagne, 2004): The time period that detection takes place: in real time (while it is taking place) or following the information only. The types of input inspected to identify intrusive action. These could comprise user shell commands, process system calls, as well as network packet headers or contents. Several types of intrusions might be identified only by correlating information from various such sources. The variety of action capabilities. Basic and straightforward types of actions consist of changing an administrator of the possible intrusion or in some way halting the potentially intrusive action, for instance,...

Intrusion Detection System

...Intrusion Detection System Introduction It is very important to keep track of all possible intrusions that a sensitive network might encounter (thesis statement). This can be done by keeping a strict check on proper configuration, management and monitoring of the firewall settings, intrusion detection system’s logs and anti-virus upgrades. A case study has been discussed here which involves a scenario where an intruder attacked port 3389 of a computer. Necessary Actions According to the case study given, the intrusion will drive me to take these actions: I shall tell myself to relax. Fright worsens the whole situation. One can think better with a composed mind. I shall take a deep breath instead of...

Intrusion Detection System

... Intrusion Detection System A system equipped to fight against firewall, malwares, and offers protection against viruses is not novice. This is because protecting the computer against these attacks is an essential part of computer management and protection policy. I agree with this argument of Justin concerning HIDS. HIDS is an intrusion detection system that screens and scrutinizes the internal parts of a computer system, and its own network interface. The system protects against attacks on the computer memory. QUESTION 2 I agree with this argument of David, since a layered defense provide security to a computing system At three different levels with the aim of preventing an attack...
