TL;DR: An overview of the algorithms, design philosophy, and implementation techniques in the software SuperLU, for solving sparse unsymmetric linear systems, and some examples of how the solver has been used in large-scale scientific applications, and the performance.
Abstract: We give an overview of the algorithms, design philosophy, and implementation techniques in the software SuperLU, for solving sparse unsymmetric linear systems. In particular, we highlight the differences between the sequential SuperLU (including its multithreaded extension) and parallel SuperLU_DIST. These include the numerical pivoting strategy, the ordering strategy for preserving sparsity, the ordering in which the updating tasks are performed, the numerical kernel, and the parallelization strategy. Because of the scalability concern, the parallel code is drastically different from the sequential one. We describe the user interfaces of the libraries, and illustrate how to use the libraries most efficiently depending on some matrix characteristics. Finally, we give some examples of how the solver has been used in large-scale scientific applications, and the performance.

TL;DR: The resulting ideas about interface design for fieldworkers are formulated into two general principles: Minimal Attention User Interfaces (MAUIs) and context awareness.
Abstract: “Using while moving” is the basic ability fieldwork users require of a mobile computer system. These users come from a wide range of backgrounds but have in common an extremely mobile and dynamic workplace. We identify four specific characteristics of this class of users: dynamic user configuration, limited attention capacity, high-speed interaction, and context dependency. A prototype is then presented that was designed to assist fieldworkers in data collection tasks and to explore the HCI design issues involved. The prototype was used in an extensive field trial by a group of ecologists observing giraffe behavior in Kenya. Following this trial, improvements were made to the prototype interface which in turn was tested in a subsequent field trial with another group of ecologists. From this experience, we have formulated our resulting ideas about interface design for fieldworkers into two general principles: Minimal Attention User Interfaces (MAUIs) and context awareness. The MAUI seeks to minimize the attention, though not necessarily the number of interactions, required from the user in operating a device. Context awareness enables the mobile device to provide assistance based on a knowledge of its environment.

TL;DR: The semantic user interface (SUI) as mentioned in this paper is a system that allows a user to use their everyday language or user defined words to operate a computer in a highly efficient way.
Abstract: A system and method that allows a user to use their everyday language or user defined words to operate a computer in a highly efficient way. In short, every word, letter, control character and symbol is potentially actionable. A computer user's productivity is dramatically increased by making available those functions that enable a user to produce most of his work through simple, language-based commands. The present invention provides an intuitive interface, referred to as a semantic user interface (SUI), that enhances the operation of the current standard window-based interface in a manner that is simple, richer and natural. By leveraging all of the richness and power inherent in a user's language, the present invention provides an important tool that allows the personal computer to operate in a manner that is much closer to our natural way of interacting. A user is allowed to enter “commands” in his everyday natural language in order to control the operations of the computer. All commands are language-based and user-defined. These commands can be entered from any context of the user's computer (e.g., any application or operating system workspace). The commands allows a user to launch applications and navigate within applications by using language rather than clicks from a pointing device such as a mouse. It also allows the replacement of keystrokes with stored words or keystrokes. The system also keeps a complete archive record of all the text content the user provides as input, regardless of which application program or operating system window the user is operating in at the time. The combined set of all user defined commands and the memory of all the input text that is stored in the archive constitutes the personality profile and is transportable from one computer to another.

TL;DR: In this article, the authors describe a system for determining dimensions of a physical object using a mobile computer equipped with a motion sensing device, which includes a microprocessor, a memory, a user interface, a motion sensor, and a dimensioning program executable by the microprocessor.
Abstract: Devices, methods, and software are disclosed for determining dimensions of a physical object using a mobile computer equipped with a motion sensing device. In an illustrative embodiment, the mobile computer can comprise a microprocessor, a memory, a user interface, a motion sensing device, and a dimensioning program executable by the microprocessor. The processor can be in communicative connection with executable instructions for enabling the processor for various steps. One step includes initiating a trajectory tracking mode responsive to receiving a first user interface action. Another step includes tracking the mobile computer's trajectory along a surface of a physical object by storing in the memory a plurality of motion sensing data items outputted by the motion sensing device. Another step includes exiting the trajectory tracking mode responsive to receiving a second user interface action. Another step includes calculating three dimensions of a minimum bounding box corresponding to the physical object.
