Forensic 3D Laser Scanning of Footwear Impression Evidence Thesis Proposal

Forensic 3D Laser Scanning of Footwear Impression Evidence - Thesis Proposal Example However, getting a 3D physical cast of an impression on a crime scene can in the process destroy the evidence. The use of 3D imaging device is proving to be beneficial to crime scene investigators (CSI) as an additional toolkit since it can obtain details of such impression. Footwear impression recovery in crime scene is considered to have a critical role in the investigations to narrow down the number of suspects or refute or corroborate information (Gamage et al., 2013). Three dimension foot ware impressions casting is seen to be a long standing standard where, it results to the generation of three dimensional footprints. This is progressively being replaced by a three dimensional scanning that is a less invasive method. In the study proposed, an alternative method that entails a 3D laser scanning of footwear impression evidence with the use of a FARO "Freestyle" 3D Scanner will be present, and it will be based on the multi-view stereo where, an accurate three dimensional model can be generated. The results on the reconstructed three dimensional models will be evaluated and then compared with other results obtained by three dimensional scanning. Also, the drawbacks and the advantages of this method will be explored over other methods that exist. Freestyle hand held scanner was recently released by FARO, and this is considered as a step up in structured light technology because it includes two cameras infrared in nature which are used in creating a stereo pair of images Three dimensional foot ware impression casting is progressively being replaced by a three dimensional scanning that is less invasive method. In the study to be undertaken, an alternative method that entails a 3D laser scanning of footwear impression evidence with the use of FARO "Freestyle" 3D Scanner will be present and it will be based on the multi-view stereo. Footwear impression recovery in crime scene is considered to have a critical role in the

Skin cancer Essay How many of you have every laid out in the sun on purpose just to get a tan?   Or better yet how many of you believe you look prettier or more handsome tan?   According to the American Cancer Society more than 1 million people are diagnosed with skin cancer each year and the numbers seem to be increasing day to day. And believe it or not skin cancer is the most common of all cancers.   Today I am going to inform you about skin cancer and how you can protect yourself from it. To begin, our skin is the largest organ of the body and it covers our internal organs and protects them from injury.   The skin also serves as a barrier between germs and our internal organs.   Our skin regulates body temperature and helps the body get rid of excess waste.   Certain cells in our skin also communicate with the brain and allow us the feel temperature, touch, and pain sensations. Some may ask, what exactly is skin cancer and why is it such a big deal now?   Well there are two basic types of skin cancer; Nonmelanoma (which is also called basal or squamous cell) skin cancer and then there is melanoma skin cancer. Most skin cancers are classified under nonmelanoma, meaning that the cells are located at the base of the outer, layer of the skin.   Basically, the skin that covers the surface of the body, not the deep tissues.   Nonmelanoma skin cancer usually develops on sun-exposed areas of the body, places like: the face, ears, necks, lips, and the backs of hands.   Depending on the type they can be fast or slow growing but rarely spreads to other parts of the body.   There is a cure for nonmelanoma skin cancer is detected and treated early. On the other hand, you have melanoma skin cancer.   Which is the more dangerous of the two; however it is also the least common.   Melanoma skin cancer tends to spread very quickly to other body parts.   However, it is almost always curable if it is detected in the early stages.   But the killer part is a lot of people do not realize that they may have melanoma skin cancer until the later stages, after it has already started affecting other organs.   Once it has reached that stage, it is virtually incurable.   People diagnosed with melanoma skin cancer that has already spread to other body parts are given on average a five year survival rate. So what puts you at risk for skin cancer?   Some high risk factors include:  · Unprotected and/or excessive exposure to Ultraviolet(uv) radiation  · Fair complexions( people with red hair, most likely)  · Occupational exposures (i.e. Construction workers, arsenic compounders, baseball players)  · Family history of skin cancer  · Multiple or atypical moles  · Severe sunburns as a child So how can you detect skin cancer? Some signs of skin cancer in the early stages may include but are not limited:  · any change on the skin, especially in the size or color of a mole or other darkly pigmented growth or spot, or a new growth  · scaliness, oozing, bleeding, or change in the appearance of a bump or nodule  · the spread of pigmentation beyond its border such as dark coloring that spreads past the edge of a mole or mark  · a change in sensation, itchiness, tenderness, or pain in a mole

The Criminal Justice System Essay -- Criminal Justice

The criminal justice system is composed of three parts – Police, Courts and Corrections – and all three work together to protect an individual’s rights and the rights of society to live without fear of being a victim of crime. According to merriam-webster.com, crime is defined as â€Å"an act that is forbidden or omission of a duty that is commanded by public law and that makes the offender liable to punishment by that law.† When all the three parts work together, it makes the criminal justice system function like a well tuned machine. In this paper, I propose to talk about how all the three parts of the criminal justice system works and also delve a little bit on the issue of racism in context of the criminal justice system as a lot of people believe that the system most of the times acts keeping the individual’s race in mind. When an individual enters the criminal justice system, it always begins with the police. So in order for police to be involved in any situation, there has to be a crime committed or violation of any law which has been put in place by the government. As the police act as the enforcement agents of these laws, they are the first ones to be involved. There are four steps that police follows when there is a crime – the crime itself, the report of the crime, the investigation of the crime, and the arrest to finish this process – these are the very basic avenues which police follows. We have already established that for the police to be involved, the crime has to be committed. Once the crime is committed, someone has to report about the crime being committed and when the report has been made, the police begin its job and starts investigating that report to determine if a crime have been committed. O... ... Simpson Trial is a real life example of how once the crime is determined, courts follow a fair trial system and then corrections follow. Again, I will take up this example and will try to explain how I think the justice prevailed in this case. Works Cited Schmalleger, F. (2009), Prentice Hall, Publication.

Self Discovery Essay -- Philosophy Philosophical Essays

Self Discovery â€Å"What are you going to do after you get your degree?†Whenever I announce my occupation, this trite, well-intentioned question never fails to follow. I am a student, a senior at Metro, studying Literature and History. Not only a student, I am a mother, wife, daughter, sister, friend and female. No, I don’t bring in a paycheck, but my life is fulfilling, gratifying, deserving and challenging. Will I teach, write, join the downtown business crew again, or become a clerk in the bookstore? Maybe I will. Whatever I do, I know I will strive to be a bit more patient, observing the tiniest of details, attempting to be more considerate and understanding of people, honoring their backgrounds and culture. While studying English and History, I have obtained a clearer sense of being. I have repeatedly professed that my family and faith prioritize my life, however, I often found that the chaos of establishing a career and pursuing the ‘American Dream’ clashed with those values. Caught in a whirlwind, life was centered around the present, focusing on the future, without the time or necessity to reflect on the past. The study of liberal arts has opened new windows to the past in my mind, allowing the wisdom and thoughts of many great people circulate and stimulate my efforts, giving credence to many of life’s blessings and insecurities. The struggles, discoveries, confessions, and pronouncements of those who are forged in history often apply to modern day life relationships.

Ibm Case Essay

History By the 1950’s, IBM became the dominant vendor in the computer industry with the release of the IBM 701 along with many other series of mainframes, which are large central processors. Then in the1960’s and 1970’s, the company had to diversify to get on the same level as smaller companies, such as Digital Equipment Corporation, who were introducing microprocessors. This threatened IBM’s position in the computer industry. Their response was coming put with a personal computer, software, and services. In 1981, IBM officially introduced the IBM PC with a compatible hardware platform. This was a large accomplishment for the company. A few years later, on May 1st, 2005, IBM sold its PC division to the Chinese company Lenovo for $655 million in cash and $600 million in Lenovo stock. Then on January 25, 2007, IBM sold their printing systems division for $725 million to Ricoh and created a new Ricoh subsidiary called InfoPrint Solutions Company. Ricoh will now own a 51% share and IBM will own a 49% share. Also in 2007, IBM’s yearly revenue was $98. 8 billion and they had a net income of $10. 8 billion dollars. IBM is run by about 427,000 employees. There are three main people who keep the business running smoothly. The most important one is Samuel J. Palmisano, who is the Chairman, President, and CEO. Another important associate at IBM is Mark Loughridge, who is the SVP and CFO. And lastly, Douglas Elix, who is another SVP, a Group Executive, and is in charge of Sales and Distribution. These three men are vital to the company’s success. Besides them, most of the employees at IBM are IT Specialists, Application Services Consultants, and Managing Consultants. Every company has to have competitors. Competition makes a healthy industry. Some of the top competitors IBM runs against are EDS (Electronic Data Systems Corporation), Hewlett Packerd, and their biggest competitor, Microsoft, whom they are ranked right behind in second place in their industry. IBM has many recent accomplishments within that last few years. One of the major ones was the development of the world’s tiniest nanophotonic switch, which is a device for routing light on a chip scale. Another project they have completed wasweb 2. security concerns with â€Å"SMash,† which is one of their development tools. Another very large project they completed was the design of the microprocessor for the Xbox 360, Playstation 3, and Nintendo Wii. All three of those were a good addition to the list of products they already design. This opened up their age range of consumers as well since a lot of children play these video systems. Besides recent accomplishments in their elec tronic field, IBM also had many of their employees win multiple awards for their achievements. They have had three of their employees win Nobel Prizes, which are achievements in either physics, chemistry, literature, peace, economics, medicine and physiology; four have received a Turing Awards, which are awards for technology; five have National Medals of Technology; and five more have received National Medals of Science. These are all very big accomplishments that IBM is very proud of. IBM is currently working on many projects. One of its big ones is Eclipse, which is a platform-independent, Java based software framework. Another is developerWorks, which is a website run by IBM for software developers and IT professionals. It contains large numbers of how-to articles and tutorials, software downloads, code samples, discussion forums, podcasts, blogs, wikis, and other resources. Then there is alphaWorks which is IBM’s source for emerging software technologies. They are also working on more semiconductor designs and manufacturing for them. Open client offering is another project they are working on. It is to run on Windows, Linux and Apples. Used for word processing, presentations, Lotus Notes, instant messaging, blogging, etc†¦ UC2: Unified Communications and Collaboration is an IBM and Cisco joint project. It will offer numerous Eclipse applications developers a unified platform for an easier work environment. Examples of this would be click-to-call and voice mailing. SWOT on Management IBM holds more patentsthan any other U. S. based technology company. IBM’s Project Management Center of Excellence, or PM COE, is first-rate. PM COE is considered IBM’s â€Å"Think Tank†. It is a program that has been set up to define the steps needed to strengthen IBM’s project management capabilities. PM COE combines external industry trends and directions with IBM business, organizational, geographic requirements and insight. Using PM COE, IBM has developed project management policy, practices, methods, and tools (Wikipedia, 2008). For someone to be considered for a management position, they must complete IBM certification or accreditation. To be accepted in to the certification or accreditation process an individual must have done the following. Successfully passed PMI exam (i. e. be a certified PMP). Verifiable documentation and approval for mastery/expertise in a well-defined set of PM skills. Several years of PM experience spanning at least 3 verifiable projects within the immediate 5 years (including specific role, team size, and budget requirements). Verifiable documentation and proof of at least one area of specialty. Demonstrated the use of IBM’s Worldwide Project Management Method (_WWPMM_). Completed extensive classroom and online education and testing. To become a Junior Project Manager, you must go through self assessment and get supervisors authorization to be accredited. Becoming a Senior Project Manager requires going through the rigorous IBM certification process, which involves Candidate preparing a detailed package with proof of above requirements. Package review, approval, and support by at least two levels of Senior Management. Package review and re-verification by PM COE expert. Personal interviews with the PM COE Certification board. Candidates whose experience, skills, knowledge and education are deemed valid, verifiable and accurate, are certified by the board as either Certified Senior Project Manager (CSPM) or Certified Executive Project Manager (CEPM). Senior Project managers must validate their skills and expertise against IBM’s worldwide standards. It is a deliberately long process with multiple checkpoints designed to ensure the integrity, fairness and legitimacy of the certification. This helps IBM maintain customer confidence in their products (Wikipedia, 2008). Since IBM is such a large, diversified, and established company they do not have many weaknesses. One weakness is they have a tendency to â€Å"strong arm† clients that are highly dependent on IBM products (Bradley, 2004). In the future this reputation could lead companies to be hesitant to rely on IBM’s merchandise. This reputation could also create bad enough relationships with current clients to make them transfer to a competitor’s product. IBM has also been known to â€Å"over promise† (Bradley, 2004). Since they are such a large corporation, with many capabilities, they tend to promise unrealistic deadlines to their customers. Businesses don’t like losing money, and opening later then planned is a good way to do that. These delays in their customers start-ups, could also lead to unfavorable relationships that could cause clients to move their business elsewhere. IBM is constantly looking for new opportunities to expand their share of the market, or start a new market. IBM is looking into revolutionizing the prevention of traditional and online fraud and Identity thefts. They are working on a comprehensive anti-fraud program that is going to help banks protect themselves and their customers, while continuing to offer their products and services (IBM, 2006). IBM is also conducting case studies for the automotive industry. The case studies are going to help them change the industry, and become more innovative (Lunani, 2006). Hopefully, the innovations will alleviate some of the stress the industry is under. Management Practices ; Theories SWOT analysis is a very important part of finding out a lot of information pertaining to current management functions within the company. However, it is what the management does after they find their strengths, opportunities, weaknesses, and threats that are the most relevant part of determining a company’s success. The theories and practices the company uses to take advantage of their strengths, try to combat their weaknesses, use opportunities to their best interest, and to defend themselves from threats are the key determinant on what the company’s future looks like. IBM as one of the top companies in the world clearly knows what they are doing. They have taken into careful consideration their SWOT analysis and their management theories and practices are derived from their analysis. Being involved in competitive global competition, the company’s workforce is an essential part to IBM’s success. In knowing of this, IBM has created a list of seven key core workforce capabilities. These capabilities include: Understanding the demographics and capabilities of the workforce, predicting future labor supply and demand, utilizing social networks to increase the visibility and application of knowledge across the organization, enabling individuals to perform work regardless of location, facilitating collaboration across traditional organizational boundaries, driving the rapid development of skills and capabilities to meet changing business conditions, and evaluating employee performance and providing appropriate feedback. IBM has implemented these guidelines so their workforces can constantly adapt to the ever changing global business environment. In addition, workers are paid incentives for their input to keep the employees with a sense of involvement which is important to keeping them excited about IBM. At IBM, the managers believe and in a workforce that is diversified. According to Ron Glover, VP for Global Workforce Diversity at IBM, focuses on what it means to retain a true culture of diversity is IBM’s greatest competitive advantage. From all the way back to World War I, IBM has romoted workforce diversity when they hired disabled veterans to work for the company. Even when no one was using diversity IBM was. Way back in 1953, CEO at the time Thomas Watson sent out a very controversial stating that IBM needs to hire the best people, regardless of their race, ethnic origin, sex. In addition, the company added sexual orientation in 1984. He knew that this would give IBM a competitive advan tage because IBM would then be able to hire talented people the it’s competitors would turn down. (hrmreport. com, 2008) Another way IBM tries to get the best workers is using their program called Extreme Blue. This is an internship program for graduate and undergraduate students. This internationally known program is great for getting students prepared to work for IBM. IBM believes this will give students interested in working for a IBM a realistic perspective on what it would be like to work for them. IBM runs this diverse workforce under a classical management perspective. Money is assumed to be the primary motive and have a traditional compensation plan. The main forms of pay to employees are base pay and valuable other forms of benefits such as retirement plans and insurances. According to the company’s website, â€Å"cash compensation opportunities include base pay, commissions, performance bonuses, awards and other forms of earnings. † In addition to these forms of pay, IBM also offers generous paid vacation and holidays. There are also some benefits to relieve stress and just get away from the company for a little while. These benefits include reduced-prices, cooking lessons, and fitness centers. This management style has worked for them and we think they should stick with the classical approach to management and not move to a behavioral perspective. IBM uses an analyzer strategy which most large companies use. An analyzer strategy is a strategy in which the firm attempts to maintain its current businesses and to be somewhat innovative in new businesses. They use this strategy because they want to produce some new product opportunities while protecting their base of operations. (Griffen, 2007) Management Structure â€Å"The management structure that IBM maintains is an effective internal control structure. This structure has clearly defined lines of responsibility, as well as comprehensive systems and control procedures. This structure is beneficial because it assures customers that their transactions are put through correctly and efficiently. â€Å"(http://sec. edgar-online. com) An important part of IBM’s management structure is a good internal audit program. IBM takes a good amount of time to train its workers correctly. Each employee receives written policies and procedures to ensure that each employee knows exactly what to do under any circumstance or problem that may arise. By doing this everyone is on the same page and everything is done the way they want it done. IBM is now thinking about cutting 13,000 jobs most of which should be mostly in Europe and other headquarters around the world. Ethics With all of the diversity that exists within the company it would be hard for IBM to conduct any work without ethics on their minds. As in any large company there is some sort of unethical behavior going on, however these behaviors have not been detrimental to the company thus far. So far it is obvious that IBM won’t make any large scale unethical decisions such as the like of Enron. The ethics are very important in the business process and will be discussed more in an interview with a former employee. Interview With a Former Employee Flat or tall management structure? â€Å"The structure tends to be taller than most companies, especially within the consulting group. † Management Style? â€Å"The managers take a very classical by the book style to their decisions. Everything that had happened before was documented and later considered protocol, if there was success. † What ethics does IBM use in decision making? â€Å"IBM has well defined guidelines on many ethical issues, and it is required that all new employees review these guidelines. Employees are also required to take an annual review test to comply with IBM corporate policy. In my experience IBM relies on individual managers to make judgment calls on grey areas, and the managers I worked with all took ethic approaches to handling the issue. † What are the area’s for improvement? â€Å"IBM has had difficulties integrating its consulting division, since the acquisition of Price Waterhouse Coopers consulting in 2002. Much effort has been focused on getting full value from this acquisition, and at least initially the purchase was viewed as a misstep. With changes over the last few years, the consulting division has become the bulk of IBM revenue, but there are still opportunities to better leverage the consulting division in light of other IBM business units. IBM has also been severally criticized for its outsourcing practices, and has taken very proactive measures to combat this public criticism. † Any alliances? â€Å"IBM has numerous alliances with companies, all the way from suppliers to working with competitors. The number of alliances in likely in the thousands. † What makes IBM so successful? The ability to solve large scale business problems, especially in the IT sector, by combining various internal specialties and partnerships to create and implement end to end solutions. † Have you witnessed any unethical behavior throughout the company? â€Å"I have not personally witnessed any unethical behavior, but have spoken to a former VP who was put in a position to take an unethical action by someone who wa s very senior in the organization. † Hiring procedures? Promotions procedures? â€Å"Hiring is done at the group level, based upon target numbers that are established at the top of the organization. Final hiring decisions are made at the senior manager level. Promotion decisions occur annually with promotions and compensation based upon the outcome of the decision. Promotion is granted if the employee can show sufficient evidence that he/she is operating at the intended promotion level, and that the results are sustainable (ie. , results must be shown for a relatively long time and consistent time period, in various situations) . The implementation of the corresponding compensation typically occurs six months after promotion decisions are made. The timing of promotions and compensation increases are an area which many employees feel needs to be corrected, and IBM has stated it intends to reduce the total time of the process. † Relationship between managers and subordinates? â€Å"Varies greatly based upon individual relationships. IBM offers many channels to discuss issues, but the design of the promotion/compensation/staffing structure makes it imperative to have a successful working relationship with direct and next level management. † Is there a lot of management restructuring? Yes, at the lower levels, especially in consulting, management roles are very fluid and change frequently in comparison with other companies. Some of this is based on market changes, some on promotions/exits, and some on business results. † What kind of fringe benefits do workers receive? â€Å"Discounts with partner companies, cell and broadband reimbursement, 401k contribution, pension (eliminated in 2006), corporate educatio n, annual bonus (consulting division), extensive health care coverage at low rates. † Is there a lot of communication between the different headquarters? Conclusion It is obvious that IBM is successful because their values and the way they conduct business. This is a direct reflection upon their management structure, style, and practices. They will surely stay on the same track of success for many years to come. As they push forward in their business they are becoming one of the most well known businesses whether it be for technology or consulting around the world. No matter what kind of work a person is in one thing is for certain, everyone can learn from the way IBM conducts their business.

How To Make Violet or Purple Fire

How To Make Violet or Purple Fire Violet flames are very easy to make. All you do is sprinkle salt substitute on your fire. Salt substitute contains potassium chloride and potassium bitartrate. If you are familiar with the emission spectra from flame tests, youll recognize that potassium salts burn violet or purple. The color seems more of a blue-violet, but you can get a more reddish purple if you mix a little strontium from the red fire tutorial in with the salt substitute. Keep in mind that violet is not one of the colors your eyes see really well. The subtle glow of these flames can be completely overwhelmed by the colors from trace impurities. This means two things: Use as pure a fuel as you can. I used Heet fuel treatment, which is methanol. If you sprinkle the salt substitute on your wood-burning campfire, the flames will change color, but the color wont necessarily be violet.Use salt substitute and not lite salt. Lite salt is a mixture of normal table salt (sodium chloride) with potassium salts. The yellow from the sodium will overpower the violet from the potassium. Watch a video of this project.
