We present a wait-free solution to the generalized dining philosophers problem under eventual weak exclusion in environments subject to crash faults. Wait-free dining guarantees that every correct hungry process eventually eats, regardless of process crashes. Eventual weak exclusion (3WX ) actually allows scheduling mistakes, whereby mutual exclusion may be violated finitely-many times; for eac...

We are what we eat. Our everyday food choices affect our long-term and short-term health. In the traditional health care, the professionals assess and weigh each individual’s dietary intake with intensive labor cost. In this paper, we have designed and implemented a dietary-aware dining table that can track what and how much we eat. To enable automated food tracking, the dining table is augment...

BACKGROUND Eating together is promoted among hospitalized seniors to improve their nutrition. This study aimed to understand geriatric patients' perceptions regarding meals in a common dining area versus at the bedside. METHODS An exploratory qualitative study was conducted. Open-ended questions were asked of eight patients recruited from a geriatric rehabilitation unit where patients had a c...

We are what we eat. Our everyday food choices affect our long-term and short-term health. In the traditional health care, professionals assess and weigh each individual’s dietary intake using intensive labor at high cost. In this paper, we design and implement a diet-aware dining table that can track what and how much we eat. To enable automated food tracking, the dining table is augmented with...

The dining philosophers problem, or simply dining, is a fundamental distributed resource allocation problem. In large scale and longlived systems, the likelihood of some process failing at some point is high, thus sparking interest in fault-tolerant versions of dining. We propose two algorithms for solving stabilizing dining with failure locality 1 in asynchronous shared-memory systems with reg...

BACKGROUND This study assessed the magnitude of secondhand smoke (SHS) exposure when people smoke in outdoor dining areas and explored conditions influencing exposure levels. METHODS Data were gathered from 69 outdoor dining areas in Melbourne, Australia, during April/May 2007. Sitting at tables within 1 metre of an active smoker, the authors measured the concentration of particulate pollutio...

Background Most states in the U.S. permit hotels to allow smoking in some guest rooms, and only five (Indiana, Michigan, North Dakota, Vermont, and Wisconsin) require that all hotel and motel rooms be 100% smoke-free (State and local 100% smokefree hotel and motel guest room laws enacted as of July 3, 2017). Little is known, however, about how hotels' smoking policies have been implemented. Thi...

Despite the significant impact of environment on the attractiveness of tourist destination, environmental stewardship is not always the top priority in the hotel industry as one of the most energy-intensive sectors of the tourism industry which contributes to the increasing quantity of air pollutants. Therefore, this study investigates the impact of ecological pull motives and service quality o...
