Continued from last month, a single series diode rectifier is excited by sinusoidal voltage source through inductor. To adjust the diode’s on-duty cycle, we now employ variable resistor for dc load, as shown in Figure 1 . Can predict specific resistance <italic xmlns:...

Multiple sclerosis (MS) and migraine are two common neurological disorders affecting women more than men. Sleep quality impairment has been reported in both diseases. The goal of this study was to compare sleep quality and depression between women with MS and migraine. Seventy women with migraine and 75 women with MS were enrolled in this study. Participants were asked to fill-out valid and rel...

The behavior of various types of noncompact covering properties such as paracompactness, metacompactness, subparacompactness, submetacompactness, etc., are studied under various types of fuzzy mappings such as open map, closed map, perfect map, etc. Moreover the concept of para-Lindelof space is introduced in L-topological spaces and its properties and behavior under maps are obtained.

— We present the first optical observations of a Gamma Ray Burst (GRB) afterglow using the 2-m robotic Liverpool Telescope (LT), which is owned and operated by Liverpool John Moores University and situated on La Palma. We briefly discuss the capabilities of LT and its suitability for rapid follow-up observations of early optical and infrared GRB light curves. In particular, the combination of a...

If the patient’s spine is anatomically abnormal or is injured, or if the patient’s posture during the lumbar puncture is insufficiently relaxed, there is a greater likelihood that the lumbar puncture needle will strike against bone and that bone marrow components will be aspirated together with the CSF. Other cell types and tissues that may appear in the CSF as an artifact of lumbar puncture ar...

Real-time traffic flow operation condition of freeway gradually becomes the critical information for the freeway users and managers. In fact, electronic toll collection (ETC) transaction data effectively records operational information of vehicles on freeway, which provides a new method to estimate the travel speed of freeway. First, the paper analyzed the structure of ETC transaction data and ...

In the traditional fuzzy logic, the expert’s degree of confidence d(A&B) in a complex statement A&B (or A∨B) is uniquely determined by his/her degrees of confidence d(A) and d(B) in the statements A and B, as f&(d(A), d(B)) for an appropriate “and”-operation (t-norm). In practice, for the same degrees d(A) and d(B), we may have different degrees d(A&B) depending on the relation between A and B....
