Proof Of Principle
Proof of concept (POC or PoC), also known as proof of principle, is a realization of a certain method or idea in order to demonstrate its feasibility, or a demonstration in principle with the aim of verifying that some concept or theory has practical potential. A proof of concept is usually small and may or may not be complete. These collaborative trials aim to test feasibility of business concepts and proposals to solve business problems and accelerate business innovation goals. A proof of value (PoV) is sometimes used along proof of concept, and differs by focusing more on demonstrating the potential customers use case and value, and is usually less in-depth than a proof of concept. Usage history The term has been in use since 1967. In a 1969 hearing of the Committee on Science and Astronautics, Subcommittee on Advanced Research and Technology, ''proof of concept'' was defined as following: One definition of the term "proof of concept" was by Bruce Carsten in the context o ...

Feasibility Study
A feasibility study is an assessment of the practicality of a project or system. A feasibility study aims to objectively and rationally uncover the strengths and weaknesses of an existing business or proposed venture, opportunities and threats present in the natural environment, the resources required to carry through, and ultimately the prospects for success.Justis, R. T. & Kreigsmann, B. (1979). The feasibility study as a tool for venture analysis. ''Business Journal of Small Business Management'' 17 (1) 35-42. In its simplest terms, the two criteria to judge feasibility are cost required and value to be attained. A well-designed feasibility study should provide a historical background of the business or project, a description of the product or service, accounting statements, details of the operations and management, marketing research and policies, financial data, legal requirements and tax obligations. Generally, feasibility studies precede technical development and projec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ewing Marion Kauffman Foundation
The Ewing Marion Kauffman Foundation (Kauffman Foundation) is a registered 501(c)(3) nonprofit, private foundation based in Kansas City, Missouri. It was founded in 1966 by Ewing Marion Kauffman, who had previously founded the drug company Marion Laboratories. The Kauffman Foundation works with communities to build and support programs that boost entrepreneurship, improve education, and contribute to the vibrancy of Kansas City. The Kauffman Fellows Program, known for supporting diversity in the field of venture capital, originated from the Kauffman Foundation. In a statement quoted by TechCrunch, fellows said that they “have measured the importance of a trusted diverse network and how it impacts the success and longevity of the best investors in the industry. Research has shown that Kauffman Fellows not only have larger returns than the industry average, but they stay in the industry 15+ years post-fellowship, which is 2X the minimum number of years it takes to recognize ...

Randomized Controlled Trial
A randomized controlled trial (or randomized control trial; RCT) is a form of scientific experiment used to control factors not under direct experimental control. Examples of RCTs are clinical trials that compare the effects of drugs, surgical techniques, medical devices, diagnostic procedures or other medical treatments. Participants who enroll in RCTs differ from one another in known and unknown ways that can influence study outcomes, and yet cannot be directly controlled. By randomly allocating participants among compared treatments, an RCT enables ''statistical control'' over these influences. Provided it is designed well, conducted properly, and enrolls enough participants, an RCT may achieve sufficient control over these confounding factors to deliver a useful comparison of the treatments studied. Definition and examples An RCT in clinical research typically compares a proposed new treatment against an existing standard of care; these are then termed the 'experimental' ...

Multicenter Trial
A multicenter research trial is a clinical trial conducted at more than one medical center or clinic. Most large clinical trials, particularly Phase III trials, are conducted at several clinical research centers. Benefits The benefits of multicenter trials include a larger number of participants, different geographic locations, the possibility of inclusion of a wider range of population groups, and the ability to compare results among centers, all of which increase the generalizability of the study. In many cases, efficacy will vary significantly between population groups with different genetic, environmental, and ethnic or cultural backgrounds ("demographic" factors); normally only geographically dispersed trials can properly evaluate this.

Phases Of Clinical Research
The phases of clinical research are the stages in which scientists conduct experiments with a health intervention to obtain sufficient evidence for a process considered effective as a medical treatment. For drug development, the clinical phases start with testing for safety in a few human subjects, then expand to many study participants (potentially tens of thousands) to determine if the treatment is effective. Clinical research is conducted on drug candidates, vaccine candidates, new medical devices, and new diagnostic assays. Summary Clinical trials testing potential medical products are commonly classified into four phases. The drug development process will normally proceed through all four phases over many years. If the drug successfully passes through Phases I, II, and III, it will usually be approved by the national regulatory authority for use in the general population. Phase IV trials are 'post-marketing' or 'surveillance' studies conducted to monitor safety over sever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Game
Video games, also known as computer games, are electronic games that involves interaction with a user interface or input device such as a joystick, controller, keyboard, or motion sensing device to generate visual feedback. This feedback mostly commonly is shown on a video display device, such as a TV set, monitor, touchscreen, or virtual reality headset. Some computer games do not always depend on a graphics display, for example text adventure games and computer chess can be played through teletype printers. Video games are often augmented with audio feedback delivered through speakers or headphones, and sometimes with other types of feedback, including haptic technology. Video games are defined based on their platform, which include arcade video games, console games, and personal computer (PC) games. More recently, the industry has expanded onto mobile gaming through smartphones and tablet computers, virtual and augmented reality systems, and remote c ...

Tech Demo
A technology demonstration (or tech demo), also known as demonstrator model, is a prototype, rough example or an otherwise incomplete version of a conceivable product or future system, put together as proof of concept with the primary purpose of showcasing the possible applications, feasibility, performance and method of an idea for a new technology. They can be used as demonstrations to the investors, partners, journalists or even to potential customers in order to convince them of the viability of the chosen approach, or to test them on ordinary users. Computers and gaming Technology demonstrations are often used in the computer industry, emerging as an important tool in response to short development cycles, in both software and hardware development. * Computer game developers use tech demos to rouse and maintain interest to titles still in development (because game engines are usually ready before the art is finished) and to ensure functionality by early testing. Short segments ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Prototyping
Software prototyping is the activity of creating prototypes of software applications, i.e., incomplete versions of the software program being developed. It is an activity that can occur in software development and is comparable to prototyping as known from other fields, such as mechanical engineering or manufacturing. A prototype typically simulates only a few aspects of, and may be completely different from, the final product. Prototyping has several benefits: the software designer and implementer can get valuable feedback from the users early in the project. The client and the contractor can compare if the software made matches the software specification, according to which the software program is built. It also allows the software engineer some insight into the accuracy of initial project estimates and whether the deadlines and milestones proposed can be successfully met. The degree of completeness and the techniques used in prototyping have been in development and debate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Development
Software development is the process of conceiving, specifying, designing, programming, documenting, testing, and bug fixing involved in creating and maintaining applications, frameworks, or other software components. Software development involves writing and maintaining the source code, but in a broader sense, it includes all processes from the conception of the desired software through to the final manifestation of the software, typically in a planned and structured process. Software development also includes research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products. Methodologies One system development methodology is not necessarily suitable for use by all projects. Each of the available methodologies are best suited to specific kinds of projects, based on various technical, organizational, project, and team considerations. Software development activities Identification of need The s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows Security Log
The Security Log, in Microsoft Windows, is a log that contains records of login/logout activity or other security-related events specified by the system's audit policy. Auditing allows administrators to configure Windows to record operating system activity in the Security Log. The Security Log is one of three logs viewable under Event Viewer. Local Security Authority Subsystem Service writes events to the log. The Security Log is one of the primary tools used by Administrators to detect and investigate attempted and successful unauthorized activity and to troubleshoot problems; Microsoft describes it as "Your Best and Last Defense". The log and the audit policies that govern it are also favorite targets of hackers and rogue system administrators seeking to cover their tracks before and after committing unauthorized activity. Types of data logged If the audit policy is set to record logins, a successful login results in the user's user name and computer name being logged as well as t ...

Winzapper
Winzapper is a freeware utility / hacking tool used to delete events from the Microsoft Windows NT 4.0 and Windows 2000 Security Log. It was developed by Arne Vidstrom as a proof-of-concept tool, demonstrating that once the Administrator account has been compromised, event logs are no longer reliable. According to ''Hacking Exposed: Windows Server 2003'', Winzapper works with Windows NT/2000/2003. Prior to Winzapper's creation, Administrators already had the ability to clear the Security log either through the Event Viewer or through third-party tools such as Clearlogs. However, Windows lacked any built-in method of selectively deleting events from the Security Log. An unexpected clearing of the log would likely be a red flag to system administrators that an intrusion had occurred. Winzapper would allow a hacker to hide the intrusion by deleting only those log events relevant to the attack. Winzapper, as publicly released, lacked the ability to be run remotely without the use of a to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sales Engineer
Sales engineering is a hybrid of sales and engineering that exists in industrial and commercial markets. An engineering degree is not mandatory for a sales engineer, as long as they have sales knowledge and sufficient technical knowledge of the service or product they are called sales engineer. Buying decisions in these markets are made differently than those in many consumer contexts, being based more on technical information and rational analysis and less on style, fashion, or impulse. Therefore, selling in these markets cannot depend on consumer-type sales methods alone, and instead it relies heavily on technical information and problem-solving to convince buyers that they should spend money on the seller's products or services, in order to meet a business need (that is, to satisfy a business case). A sales engineer is thus both "a salesperson that understands and can apply engineering" and "an engineer that understands how to sell engineered systems". They thus not only sell but ...
