Jointly positioning multiple users in aid of user-to-user distances
2017 IEEE 28th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2017A multiuser positioning algorithm in aid of user-to-user (U2U) distances is proposed in this paper. The cost function is the combination of non-linear least squares (NLS) of time of arrival (TOA) of multiple users and the NLS of U2U distances among users. Particle swarm optimization (PSO) is applied to search the best positions of the multiple users in

User Equilibrium with Length Constrained Users
2012 Fifth International Joint Conference on Computational Sciences and Optimization, 2012In this paper we introduce a length constrained user equilibrium model. In our model, people consider two criteria, path time and path length, when selecting their routes. They only travel on "acceptable paths", the paths whose length are not too long for them.

Proceedings of the 2017 ACM Symposium on Document Engineering, 2017
Document engineering is all about building systems and tools that allow people to work with documents and document collections. A key aspect is the usefulness and usability of these tools. In this tutorial, we will look at the many different kinds of user studies and user evaluations that can be used to inform the design and improve utility and ...

A Comparison of Marijuana Users and Non-users
Nature, 1970Interviews with sixty-two Americans in their twenties, mostly students, demonstrate that those who smoked marijuana moderately differed little in personality from those who did not indulge, but that heavy smokers of marijuana were rather less conventional. The smokers tended to drink little alcohol.

User cube: a taxonomy of end users
Communications of the ACM, 1989The user cube, a precise and comprehensive graphical taxonomy designed to provide a common base for understanding and classifying end users in organizations, can be used to assess the risks associated with end-user computing.

User Authentication Based on Representative Users
IEEE Transactions on Systems, Man, and Cybernetics, Part C (Applications and Reviews), 2012User authentication based on username and password is the most common means to enforce access control. This form of access restriction is prone to hacking since stolen usernames and passwords can be exploited to impersonate legitimate users in order to commit malicious activity. Biometric authentication incorporates additional user characteristics such

User Property, User Rights, and User Privileges
2017This chapter proposes two principles that should inform the development of copyright law and policy and of user rights. The first calls for more cohesion between copyright law, private law, and public law, and for less exceptionalism in copyright law.

The proximity of users to user services
Proceedings of the 5th annual ACM SIGUCCS conference on User services - SIGUCCS '77, 1977The title of this paper is a purposeful misreading of a suggested topic that is designed to stress a major fact of CUNY/UCC life. The City University of New York consists of 21 individual units scattered throughout the five boroughs of New York City with a total constituency of 250,000 people.

Putting the user in user-interface testing
IEEE Software, 1996Discusses one of the most basic topics in user-interface design: how to run a user test. No matter how good we are at designing a user interface, we must always test it with real users to see whether it is as usable as we hope. The three main rules of user testing are: get real users, have them do real tasks, and shut up while they are trying.

The Framy user interface for visually-impaired users
2011 Sixth International Conference on Digital Information Management, 2011We have developed a multimodal interface; Framy to effectively display large 2-dimenetional data sets such as geographical data on a mobile interface. We have now extended this to be used by visually-impaired users. A pilot study that we conducted, and the interviews with a group of potential stakeholders, helped us to detect some critical problems ...
