We introduce a new family of continuous distributions and study the mathematical properties of the new family. Some useful characterizations based on the ratio of two truncated moments and hazard function are also presented. We estimate the model parameters by the maximum likelihood method and assess its performance based on biases and mean squared errors in a simulation study framework.
In this study, tactile sensitivity of gloved hand in the cold operation has been investigated. The relations among physical properties of protective gloves and hand tactile sensitivity and cold protection were also analysed both objectively and subjectively. Subjects with various gloves participated in the experimental study during cold exposure at different ambient temperatures of -12°C and -25°C
This paper presents a procedure to derive a thermal lumped-parameter grey-box model of an electric machine built for traction. The procedure includes experimental data logged under overload conditions for accurate temperature prediction at high currents, and features a relatively simple loss estimation approach. Validation of the model shows a good fit between measured and simulated results. Possi
Hydropower is one of the renewable energy sources having the highest conversion efficiency than other renewable energy sources. The hydro turbine is considered as the main component of a hydropower plant and operation and maintenance of various components are the critical issues for optimal energy generation. Under the present paper, a comprehensive literature review on the operation and maintenan
Excited states in (196)AU, populated in the Pt-196(p,n) and (d,2n) reactions, were investigated by in-beam gamma -ray and conversion-electron spectroscopy. Two only weakly connected level structures, built on the 2(-) ground state (negative-parity level scheme) and on the 5(+) isomer at 84.7 keV (positive-parity level scheme), are observed. The point of main effort of the present work was the inve
On the basis of the Agent-action-Objective (AaO) paradigm, it will be shown how the transformation of a word model to a geometric space description can be made the founda¬tion for an approach to informational invariants. In particular, the word model of a Causal Loop Diagram (CLD) has been used for simplifying the involved procedures. Since the explanation of a causal loop requires a verbal descri
This article presents a comprehensive database featuring the digitized, cleaned, geocoded, and linked data of the Swedish manufacturing censuses between 1863 and 1900. The data covers close to the universe of Swedish manufacturing activity and includes establishment-level information on workers, the sum of production value, and toll as output value. The article describes how the data was originall
As more offshore wind parks are commissioned, the focus will inevitably shift from a planning, construction, and warranty focus to an operation, maintenance, and investment payback focus. In this latter case, both short-term risks associated with wind turbine component assemblies, and long-term risks related to integrity of the support structure, are highly important. This research focuses on the
The Short Pulse Facility (SPF) of the MAX IV Laboratory in Lund, Sweden features the production of ultrashort, incoherent x-ray pulses. It is driven by a 3-GeV linac and comprises two 5-metre undulator modules. While the SPF is designed for spontaneous radiation, we explore alternative operation modes in which the SPF functions as a simple free-electron laser (FEL). In this article, we characteriz
Vertical nanowire MOSFETs exhibit asymmetric gate capacitances, allowing for their independent engineering to improve device high frequency performance. Minimizing gate-drain parasitic capacitance with the use of a vertical sidewall spacer enables universal feedback neutralization and a unilateral circuit design. For vertical spacer thickness above 20 nm, the gate-drain capacitance variability is
Fermentation intensification is crucial for the economic viability of biobased chemical production through fermentative routes, including a shift from batch/fed-batch to continuous fermentations to enhance volumetric productivity. This is especially relevant for the Acetone Butanol Ethanol (ABE) fermentation due to low productivities and concentrations caused by product toxicity. However, transiti
HCCI combustion is well known and much results regarding its special properties have been published. Publications comparing the performance of different HCCI engines and comparing HCCI engines to conventional engines have indicated special features of HCCI engines regarding, among other things, emissions, efficiency and special feedback-control requirements. This paper attempts to contribute to th
The aim of this study is to investigate whether current statistics can quantify the benefits of fire brigades. A detailed investigation by the London Fire Brigade of most fires in the greater London area has been underway since 1994. The present study concerns 307 fires in non-residential buildings between 1994 and 1997. Times to detection, to arrival of the fire brigade, and to extinguishment of
At Sjölunda WWTP, a full-scale SBR for treatment of mesophilic sludge digester liquor has been operated almost a year with stable nitrite accumulation. Only nitritation of the sludge liquor is needed since the oxidized ammonium is denitrified in the first anoxic zone of the high-loaded activated sludge in the main plant. The process strategy was to have an ammonium set-point to end the aeration, a
As companies compete on the global market with an increasing amount of competitors trying to win market shares the need for an increasingly effective production becomes apparent. By utilizing the correct indicators the company can identify and improve their weaknesses to becoming more effective. The project is performed at five of Alfa Laval’s production sites, 1, 2, 3, 4 and 5. The study is also
