Abstract:
Over the past decade, interval arithmetic (IA) has been used to determine tolerance bounds of phased-array beampatterns. IA only requires that the errors of the array elements are bounded and can provide reliable beampattern bounds even when a statistical model is missing. However, previous research has not explored the use of IA to find the error realizations responsible for achieving specific bounds. In this study, the capabilities of IA are extended by introducing the concept of “backtracking,” which provides a direct way of addressing how specific bounds can be attained. Backtracking allow

Traditional tolerance analyses such as the worst case methods and the statistical methods are applicable to rigid body assemblies. However, for flexible sheet metal assemblies, the traditional methods are not adequate: the components can deform, changing the dimensions during assembly.

Two basic configurations, assembly in series and assembly in parallel, are investigated using analytical methods.

Abstract:
When a computer system schedules jobs there is typically a significant cost associated with preempting a job during execution. This cost can be incurred from the expensive task of saving the memory’s state or from loading data into and out of memory. Thus, it is desirable to schedule jobs non-preemptively to avoid the costs of preemption. There is a need for non-preemptive system schedulers for desktops, servers, and data centers. Despite this need, there is a gap between theory and practice. Indeed, few non-preemptive online schedulers are known to have strong theoretical guarantees. This gap

Currently, permanent-magnet-type traction motors drive most electric vehicles. However, the potential demagnetization of magnets in these motors limits the performance of an electric vehicle. It is well known that during severe duty, the magnets are demagnetized if they operate beyond a ‘knee point’ in the B(H) curve. We show herein that the classic knee point definition can degrade a magnet by up to 4 grades. To prevent consequent excessive loss in performance, this paper defines the knee point k as the point of intersection of the B(H) curve and a parallel line that limits the reduction in i

Among patients who are alive and recurrence free at 2 years after HCT, survival at 10 years is between 80% and 92%. Advances in transplantation practices have led to improved outcomes and more long-term HCT survivors.

Endpoint comparisons also cannot inform the management of intermediate mosaic landscapes.

Abstract:
Over the past decade, GPS-enabled traffic applications such as Google Maps and Waze have become ubiquitous and have had a significant influence on billions of daily commuters’ travel patterns. A consequence of the online route suggestions of such applications, for example, via greedy routing, has often been an increase in traffic congestion since the induced travel patterns may be far from the system optimum. Spurred by the widespread impact of traffic applications on travel patterns, this work studies online traffic routing in the context of capacity-constrained parallel road networks and ana

Abstract:
The Euro 6 emission standard required compliance with legal exhaust emissions limits for newly registered vehicles and obligates light duty vehicle manufacturers to respect the 160,000 km durability requirements for in-service conformity. Although there is no legal limit set for fuel consumption, manufacturers are obligated to decrease the carbon footprint of vehicle fleets in order to obtain carbon neutral mobility beyond 2035. The aim of this paper is to analyse the impact of various oils’ and viscosity grades’ degradation on the change in break specific fuel consumption (BSFC) measured over

Methods: We evaluated 78 consecutive pts (76 F, median age 61 yy) with TTC occurring between 2002 and 2008 at the Tako-Tsubo Cardiomyopathy Italian Network (TIN) Centers. All pts fulfilled the following diagnostic criteria for TTC: transient akinesia/diskinesia beyond a single major coronary artery vascular distribution; no angiographic evidence of significant coronary artery disease; new electrocardiographic changes; absence of intracranial bleeding, pheochromocitoma, myoca

Abstract:
Introduction: Game Culture and GenderAs texts with the potential to help mediate specific forms of identity, video games are rich and complex sites for analysis. A tendency, however, still exists in scholarship to treat video games as just another kind of text, and work that explores the expression of masculine identity persists in drawing from cinematic analysis without proper consideration of game design and how these games are played (Triana). For example, insights from studies into horror cinema may illuminate the relationship between players and game systems in survival horror video games

For the past twenty years, academics and other social commentators have, by and large, shared the view that the phase of modernity through which we are currently passing is defined by two interrelated catalysts of change: the physical movement of people and the virtual movement of information around the globe. As we enter the second decade of the new millennium, it is certainly a timely moment to reflect upon the ways in which the prognoses of the scholars and scientists writing in the late twentieth century have come to pass, especially since—during the time this special issue has been in pre

Each certainty is as carelessly dropped as it was once carelessly assumed. The sounds of lower Manhattan that used to serve as white noise for residents—sirens, screeches, screams—are no longer signs without a referent. Instead, they make folks stare and stop, hurry and hustle, wondering whether the noises we know so well are in fact, this time, coefficients of a new reality. At the time of writing

IntroductionTasmania hangs from the map of Australia like a drop in freefall from the substance of the mainland. Often the whole state is mislaid from Australian maps and logos (Reddit). Tasmania has, at least since federation, been considered peripheral—a region seen as isolated, a ‘problem’ economically, politically, and culturally. However, Tasmania not only cleaves to the ‘north island’ of Australia but is also subject to the gravitational pull of an even greater land mass—Antarctica.

Introduction Amidst ecological collapse and environmental catastrophe, humankind is surrounded by indications that our habitat is turning against us in monstrous ways.

Such cultural manifestations of planetary catastrophe are particularly evident in video game monsters. These virtual figures continue monsters’ long-held role in reflecting the socio-cultural anxieties of their particular era. The horrific figures that monsters present pl

For many, caring is a 24 hour-a-day job with emotional, physical and financial impacts, with implications for their participation in employment, education and community activities.

The Digital TurnMuch of the 19th century disappeared from public view during the 20th century. Historians recovered what they could from archives and libraries, with the easy pickings-the famous and the fortunate-coming first. Latterly, social and political historians of different hues determinedly sought out the more hidden, forgotten, and marginalised. However, there were always limitations to resources-time, money, location, as well as purpose, opportunity, and permission.
