Recently, we proposed using Capon's minimum variance principle to find the fundamental frequency of a periodic waveform. The resulting estimator is formed such that it maximizes the output power of a bank of filters. We present an alternative optimal single filter design and then proceed to quantify the similarities and differences between the estimators using asymptotic analysis and Monte Carlo s
Meat cutting is associated with several ergonomic risk factors and a high risk of musculoskeletal disorders. The development of new production systems points to an increased degree of mechanization; instead of subdividing split carcasses of pigs with a knife, the halves are trisected by an electrical saw into 'sixth-parts', resulting in shorter work cycles for the workers. Recently, machine-direct
Popular Abstract in Swedish Antenner finns idag nästan överallt: i mobiltelefoner, bärbara datorer, surfplattor, kameror, skrivare, klockor och armbandsur, o.s.v. De används för att överföra information trådlöst mellan enheter med hjälp av elektromagnetiska vågor (som har egenskapen att utbreda sig, ungefär på samma sätt som vågorna rör sig på en vattenyta när man kastar en liten sten). Ju mer avA method to estimate Q and QZ' of antennas from single-frequency current distributions is described. This single-frequency method and the concepts of physical bounds on antenna parameters and optimum current distributions are applied to different analysis and design situations of two-dimensional and three-dimensional radiating structures (i.e., antennas). The situations considered are: antenna opt
BACKGROUND/OBJECTIVES:In studies performed in mice, rose hip powder has been shown to both prevent and reverse high-fat diet-induced obesity and glucose intolerance as well as reduce plasma levels of cholesterol. The aim of this study was to investigate whether daily intake of rose hip powder over 6 weeks exerts beneficial metabolic effects in obese individuals.SUBJECTS/METHODS:A total of 31 obese
Rheumatoid arthritis (RA) is a polygenic and multifactorial disease. Many complex immunological and genetic interactions are involved in the final out come of the clinical disease. To understand the various disease pathways operating during the disease course, we need many different animal models. Collagen induced arthritis (CIA) is one of the widely used animal models sharing many pathological an
PURPOSE: To investigate the role that both patient and outpatient factors related to health care practice (HCP) play in physicians' early adoption of rosuvastatin. MATERIALS AND METHODS: Generalized estimation equations (GEEs) and alternating logistic regression (ALR) with pair-wise odds ratios (PWORs) were used to measure similarities in rosuvastatin prescription within HCPs for all individuals w
Measurements of natural radiative lifetimes in atomic tellurium in the 5 p(3)7p configuration are reported. Two-step laser excitation was applied on tellurium vapour in a cell that was differentially heated and pumped through a capillary. The decay of the fluorescence signal was recorded at different vapour pressures. The following four radiative lifetime values were obtained: 7p P-5(1): 128(11) n
BACKGROUND: The CA-125 tumor marker has limitations when used to distinguish between benign and malignant ovarian masses. We therefore establish likelihood curves of six subgroups of ovarian pathology based on CA-125 and menopausal status.METHODS: This cross-sectional study conducted by the International Ovarian Tumor Analysis group involved 3,511 patients presenting with a persistent adnexal mass
Successful development of software systems involves efficient navigation among software artifacts. However, as artifacts continuously are produced and modified, engineers are typically plagued by challenging information landscapes. One state-of-practice approach to structure information is to establish trace links between artifacts, a practice that is also enforced by several development standards
Strain localisation plays a key role in the deformation of granular materials. Such localisation involves bands of just a few grains wide, which dominate the material's macroscopic response. This grain-scale phenomenon presents challenges for continuum modelling, which is the rationale behind models that explicitly take micro-scales into account. These in turn require micro-scale experimental anal
Electron–ion coincidence measurements with energy-resolved electrons are a powerful tool in studies of molecular fragmentation processes, since fragmentation from a specific doorway state can be monitored while the remaining reactions are discriminated. Presently, we have applied this technique in measurements of coincidence spectra of the CD4 and SF6 molecules after valence and core electron exci
