Search Patterns

When a crime has been committed and investigators need to search for evidence, there are different search patterns that investigators can choose from. These search patterns include spiral, line, zone, and grid (Siegel & Mirakovits, 2013). Depending on the crime scene, the investigator will choose from one of these search patterns that will best utilize the search for evidence. When an investigating team needs to search for evidence in a field where the field is overgrown, a grid search is a good search to utilize. When a field is overgrown, the searches may have to crawl on their hands and knees to locate any evidence and perform a thorough search. A grid line search consists of searchers following a line pattern and then following another line pattern that is perpendicular to the first line pattern (Lee, Palmbach, & Miller, 2001). The grid search pattern is a good search to utilize because it allows two different searchers, or the same searcher, to search the same area twice. Therefore, the searchers a more likely not to miss any evidence that needs to be collected. A con to the grid line search is that it is very time consuming and if the boundaries to be searched are not well established, than the search will not be very thorough (Lee, Palmbach, & Miller, 2001). The grid line search was chosen for this scenario because a thorough search can be accomplished by having two different searchers look over the same area. If one searcher missed evidence that could be pertinent to the case, the other searcher is likely to notice the missed evidence. Another search pattern that would be very effective in this type of scenario would be a line search. During a line search, searchers walk arm lengths apart from one end of the scene to the other end, move a little farther from where they just walked, and walk back toward the other end. This type of search would be useful because it is somewhat similar to the grid line search. More than one searcher is used and they walk side by side looking for any evidence. They know where the boundaries begin and end. A successful investigator should have a strong foundation in report writing so the judge, jury, and prosecutor will be able to understand how the crime occurred (Byrd, 2015). The documentation done by the investigator should tell the story of what took place during the crime and should contain only facts of the crime, not opinions, conclusions, or analysis. Another reason to have a strong foundation in report writing is if a case goes cold and another investigator takes over the cold case years later, that investigator will be able to visualize how the crime occurred, understand the evidence that was collected at the scene, and what lab reviewed the evidence that was collected. If an investigator does not have a strong foundation in report writing, then there is a chance that any evidence collected could be inadmissible in court (Byrd, 2015). The types of information that would be included in the report regarding this investigation would be photographs of the crime scene, notification information, arrival information, scene description, victim description, crime scene team, sketch of the crime scene, and information pertaining to what lab the evidence was transferred to for processing (Miller, n.d.). The investigators opinions, analysis, or conclusions should not be included on the report (Ramirez & Parish-Fisher, 2012). When an investigator includes opinions, analysis, or conclusions, the investigator is not describing the facts of the crime scene. This could cause the report to be inadmissible in court because the report could sway a jury (Ramirez & Parish-Fisher).

How to Save Money at the Fabric Store

...Cheaper to Sew Clothes than Buy them at the Store?, but thought you’d like to know some more specific ways to save money at the fabric store. Wait to Buy Patterns Until They’re on Sale When patterns aren’t on sale, they easily cost upwards of $15. Sure, that might be worth your money if you’re going to reuse it over and over again, but I still can’t bring myself to pay full price for one. If you have the time to wait, several fabric stores have sales where patterns are less than $2 a piece — that’s when I like to stock up. Alternatively, you can find sewing patterns and tutorials on the Internet for a low cost, or even free, like at Pattern Playground. I’ve also found that online sewing tutorials are easier to follow than typical sewing patterns anyway, because they are usually accompanied by videos or step-by-step pictures. If you’ve never sewn anything before, I suggest that you start with online tutorials for this very reason. Use Coupons at the Register Another way to save money at the fabric store is to use coupons. Fabric stores often run ads that give you a percentage off your entire purchase price. Some fabric stores even have coupons that give you a large discount on a single cut of fabric. I make it a rule never to go to the fabric store without one of these fabric store coupons. It’s pretty easy to search for coupons on the Internet and then print them out before you go. Jo-Ann Fabric runs promotions like this all the time. Buy Seasonal Fabric Most......

Video Data Mining

...a video can be viewed as a series of images, which contains a lot of various concepts. Even though the annotation for the individual image frame is in effect, any concept in the image frames still cannot represent the complete video. The aim of the paper is to allow users to obtain their desired videos by submitting her/his interested video clips, without considering the identification of the query terms and applying an efficient indexing technique for searching videos present in large multimedia repositories. Keywords Video data mining, multimedia repository, index table, query clip. 1. INTRODUCTION Data mining is the process of posing various queries and extracting useful and often previously unknown and unexpected information, patterns, and trends from large quantities of data, generally stored in databases[1]. These data could be accumulated over a long period of time or they could be large data sets accumulated simultaneously from heterogeneous sources. Video mining is considered as an extension of still image mining by including mining of temporal image sequences. However, the video data in the general case represent the multimedia already since they include – besides the image sequence – audio data and textual annotations. The searching of video data to find the best matching video clip in content to the desired clip of the user is a very challenging task[4]. We approach...

...February Opportunity Recognition as Pattern Recognition: How Entrepreneurs “Connect the Dots” to Identify New Business Opportunities by Robert A. Baron* Executive Overview How do entrepreneurs identify opportunities for new business ventures? One possibility, suggested by research on human cognition, is that they do so by using cognitive frameworks they have acquired through experience to perceive connections between seemingly unrelated events or trends in the external world. In other words, they use cognitive frameworks they possess to “connect the dots” between changes in technology, demographics, markets, government policies, and other factors. The patterns they then perceive in these events or trends suggest ideas for new products or services—ideas that can potentially serve as the basis for new ventures. This pattern recognition perspective on opportunity identification is useful in several respects. First, it helps integrate into one basic framework three factors that have been found to play an important role in opportunity recognition: engaging in an active search for opportunities; alertness to them; and prior knowledge of an industry or market. In addition, it also helps explain interrelations between these factors (e.g., the fact that active search may not be required when alertness is very high). Second, a pattern recognition perspective helps explain why some persons, but not others, identify specific opportunities. Third, a pattern recognition......

...in this phrase. Exam is matched to the word Example as seen here. In order to for the word to be matched, using just plain vision was possible, however, in a computer sense; one must use a pattern matching string so that the program would be able to find the match. When using coding to determine if there is a match in the pattern, you would use the RegularExpression namespace. This will allow for easy parsing and matching of strings to a specific patter (miscrosoft.com, 2011). Regex myRegEx = new Regex("exam"); string s1 = "There exists just a single example."; if (myRegEx.IsMatch(s1)) Console.WriteLine("Match found!"); Explain how you could 'teach' a computer to match the word 'exam' in the given phrase above. In order to do this in C#, you could write 4 separate search commands, or you can be more efficient and you can do it in a single phrase. By using pattern = ‘e ?x ?a ?m?’; . now you can locate one or more of the strings with just a single command: Text = [‘There exists just a single example’]; Regexp (text, pattern, ‘match’) Ans = ‘exam’. This is just one of many ways that you could teach a computer to find the word exam in the phrase. You are also able to use different MATLAB returns (MathWorks.com, 2011). Boyer-Moore pattern matching algorithm The algorithm works by creating a “skip table” to each possible character. By using this skip table, the number of actual comparisons needed to locate a string can......

Also they seem to define 3 aspects in which the machine can learn with respect to, which are: 1. Performance (P). 2. Task (T). 3.

...system is a computer application for automatically identifying or verifying a person from a digital image or a video frame from a video source. One of the ways to do this is by comparing selected facial features from the image and a facial database. It is typically used in security systems and can be compared to other biometrics such as fingerprint or eye iris recognition systems. ------------------------------------------------- Techniques Traditional Some facial recognition algorithms identify facial features by extracting landmarks, or features, from an image of the subject's face. For example, an algorithm may analyze the relative position, size, and/or shape of the eyes, nose, cheekbones, and jaw. These features are then used to search for other images with matching features. Other algorithms normalize a gallery of face images and then compress the face data, only saving the data in the image that is useful for face recognition. A probe image is then compared with the face data. One of the earliest successful systems is based on template matching techniques applied to a set of salient facial features, providing a sort of compressed face representation. Recognition algorithms can be divided into two main approaches, geometric, which looks at distinguishing features, or photometric, which is a statistical approach that distills an image into values and compares the values with templates to eliminate variances. Popular recognition algorithms include Principal......

Content Based Image Retrieval is an efficient method to do this. Many texture based CBIR methods have been proposed so far for better and efficient image retrieval. We aim to give a better image retrieval method by extending the Local Tetra Patterns (LTrP) for CBIR using texture classification by using additional features like Moment Invariants and Color moments. These features give additional information about the color and rotational invariance. So an improvement in the efficiency of image retrieval using CBIR is expected. Keywords— Content Based Image Retrieval (CBIR), Local Tetra Patterns (LTrP), Gabor Filters, Histogram Equalization, Moment Invariants I. INTRODUCTION The explosive growth of digital libraries due to Web cameras, digital cameras, and mobile phones equipped with such devices is making the database management by human annotation an extremely tedious and clumsy task.

Selenium

...Selenium Reference Concepts A command is what tells Selenium what to do. Selenium commands come in three 'flavors': Actions, Accessors and Assertions. Each command call is one line in the test table of the form: |command |target |value | Actions are commands that generally manipulate the state of the application. They do things like "click this link" and "select that option". If an Action fails, or has an error, the execution of the current test is stopped. Many Actions can be called with the "AndWait" suffix, e.g. "clickAndWait". This suffix tells Selenium that the action will cause the browser to make a call to the server, and that Selenium should wait for a new page to load. Accessors examine the state of the application and store the results in variables, e.g. "storeTitle". They are also used to automatically generate Assertions. Assertions are like Accessors, but they verify that the state of the application conforms to what is expected. Examples include "make sure the page title is X" and "verify that this checkbox is checked". All Selenium Assertions can be used in 3 modes: "assert", "verify", and "waitFor". For example, you can "assertText", "verifyText" and "waitForText". When an "assert" fails, the test is aborted. When a "verify" fails, the test will continue execution, logging the failure. This allows a single "assert" to ensure that the application is on the correct page, followed by a bunch of "verify" assertions to test form field......

Analyzing Anti-Pattern Detection

...Analyzing Anti-pattern Detection Southern Methodist University Abstract A design pattern is a well-understood, reusable design fragment used to solve a commonly occurring problem in software development. Whereas, antipatterns are common design pitfalls that provide poor solutions to recurring design problems. Developers may unwillingly introduce anti-patterns in their software systems due to time pressure, lack of skills, communication or understanding. Anti-patterns have a negative effect on the comprehension and maintainability of a software system, and thus, understanding and detecting Anti-patterns provides the knowledge to prevent or recover from them. This paper discusses the anti-patterns of object oriented design, their symptoms, and consequences and issues related to their detection. This study also discusses some of the tools and approaches that are currently being developed and used in the software industry to detect anti-pattern. Towards the end, this paper also highlights some of the problems that are still open, to drive future research direction in this field. 1. Introduction Now-a-days, most of the software projects deal with large number of components that make the software more complicated and hard for novice designers to design. A design pattern is one of the most simple and powerful techniques used to improve the software design. Unfortunately, due to a number of market/customers constraints, anti-patterns may......

Neural Networks for Matching in Computer Vision

...Neural Networks for Matching in Computer Vision Giansalvo Cirrincione1 and Maurizio Cirrincione2 Department of Electrical Engineering, Lab. CREA University of Picardie-Jules Verne 33, rue Saint Leu, 80039 Amiens - France exin@u-picardie.fr Universite de Technologie de Belfort-Montbeliard (UTBM) Rue Thierry MIEG, Belfort Cedex 90010, France maurizio.cirricione@utbm.fr 1 2 Abstract. A very important problem in computer vision is the matching of features extracted from pairs of images. At this proposal, a new neural network, the Double Asynchronous Competitor (DAC) is presented. It exploits the self-organization for solving the matching as a pattern recognition problem. As a consequence, a set of attributes is required for each image feature. The network is able to find the variety of the input space. DAC exploits two intercoupled neural networks and outputs the matches together with the occlusion maps of the pair of frames taken in consideration. DAC can also solve other matching problems. 1 Introduction In computer vision, structure from motion (SFM) algorithms recover the motion and scene parameters by using a sequence of images (very often only a pair of images is needed). Several SFM techniques require the extraction of features (corners, lines and so on) from each frame. Then, it is necessary to find certain types of correspondences between images, i.e. to identify the image elements in different frames that correspond to the same element in the scene. This......

Handbook of Od

...5 Four General Strategies for Changing Human Systems ROBERT E. QUINN SCOTT SONENSHEIN I n this chapter we articulate a new general strategy for effecting change in human systems. To do this, we return to the fundamental assumptions of organization development (OD). In examining the early arguments in the field, we identify an essential strategy that has never been made explicit. By developing this strategy, we open avenues for research and provide an action framework that will increase the effectiveness of change agents. FOUNDATIONS OF OD We begin with a review of the seminal paper published in 1969 by Chin and Benne, “General Strategies for Effecting Changes in Human Systems.” In the paper, Chin and Benne outline three general strategies for changing human systems: empirical–rational, power–coercive, and normative–reeducative. The empirical–rational strategy considers people to be rationally self-interested. An organization member adopts a proposed change if the following two conditions are met: The proposed change is rationally justified, and the change agent demonstrates the benefits of the change to the change target. In short, the rational–empirical approach emphasizes that if the target has a justifiable reason to change (i.e., if it is in his or her self-interest), change comes from simply telling the target about the change. Chin and Benne call their second strategy power–coercive. This approach focuses on change efforts in which a more powerful person......

Crime Scene Investigator

...Crime scene investigation is the meeting point between science, logic and law. Processing a crime scene is and long and tedious process and is the job of crime scene investigators (CSI). CSI has the responsibilities of collecting, documenting, preserving, reconstructing and presenting evidence. It is their job to examine any physical evidence that could remotely shed any light on what happened and who is responsible. There are no typical crime scenes, evidence or investigative approaches and every crime scene should be approached in a systematic sense. According to Robert R. Ogle Jr., a crime scene search is defined as a systematic, methodical search for any physical evidence at a crime scene. Before the job of CSI can begin, there has to be a crime committed. For instance, CSI are on call for murder scene investigations to collect and examine evidence. When CSI is contacted, their job begins. Evidence is a major part in any investigation. Without evidence, a case can grow cold quick. Anything can be evidence and when in a crime scene, everything should be treated as such. Evidence has many different categories: trace, firearm, impression, drug and alcohol, document, and biological fluids. All of these categories of evidence play an important part in finding out valuable information towards solving a case. The most important aspect of evidence collection and preservation is protecting the crime scene. When first approaching a crime scene, first responders should secure......
