Beautiful music requires precisely tuned instruments. Tuning a guitar is a necessary skill for any guitarist on their first day. This work demonstrates an understanding of the critical characteristics that must be considered while developing an acoustic guitar tuner and the logical process used to design such a tuner. The study aimed to create an algorithm using the Butterworth Filter and Fast Fourier Transform (FFT) capable of adequately analysing the frequency spectrum of a plucked guitar string to determine its fundamental frequency. The developed system compared the detected frequency and the standard frequency of the picked guitar string, which then requested the user on the tuning state of that corresponding string. The error in frequency detection was found to be in the order of 0.02%. The MATLAB App Designer tool created a Graphical User Interface (GUI) that users could use to tune guitars using the generated application easily. The implemented tuner overcame the steep learning curve and high sensitivity of traditional ones.
The hemangioma is a hamartomatous malformation and not a true tumorous of the hemangioma occur during childhood. It affects three girls for every boy. Commonest site of involvement is skin. Nerve originating hemangioma refers when it arises from the vessels supplying the nerve (vasa nervosum). It is very rare condition and presents painful, soft, compressible swelling in the course of nerve. Microscopically, hemangioma consist of poorly demarcated, non-capsulated masses and leashes of vascular channels, most of which contain blood. Although diagnosis is clinical; FNAC, Doppler Ultrasonogram study, MRI and EMG all investigations are helpful for confirmation. Surgery is the main stay of treatment but recurrence may occur. Per-operative microsurgical facility and in recurrent cases, administration of corticosteroid can prevent recurrence. We have operated one case with our own circumstances and patient has got uneventful recovery in one year follow up. EMCJ. January 2022; 7(1): 32-35
Background: The Functional Independence Measure (FIM), a part of the Uniform Data System for Medical Rehabilitation (UDSMR), examines key gradations in function from full independence to entire support using a 7-level scale to evaluate performance of essential daily living tasks (18 questions). Objectives: The objectives of this study were to develop a culturally adapted Bangla version of FIM and to test its reliability and validity in stroke patients. Materials and Methods: From March 2013 to February 2014, this observational research was conducted in the departments of physical medicine and rehabilitation and neurology at Bangabandhu Sheikh Mujib Medical University (BSMMU). Following recognized cross-cultural adaption techniques that Beaton et al., advised, the FIM was translated into Bangla. The final Bangla version of the FIM was then administered to 48 stroke patients for interviews in order to assess reliability and validity, and the same patients were re-interviewed one week later. Internal consistency (Cronbach's alpha), inter-rater reliability, and the intraclass correlation coefficient were used to evaluate dependability (ICC). Three professional physiatrists assessed the content validity, and construct validity was examined by relationship with the SF- 36's Physical Functioning Subscale (PF-10). Results: The Bangla version of the FIM was easily understood by 85-42% of respondents, whereas 10.42%(5) had trouble understanding one item and 4.17%(2) had trouble understanding two (n=48). All FIM items received responses from all participants. It was determined to contain 100% genuine material. The 35% ceiling effect was only seen in the cognitive score. For the overall FIM score, internal consistency was determined to be Cronbach's a = 0.97, and the estimated total FIM Intra-class Correlation Coefficient (ICC) was 0.95, with 0.92 for the motor subtotal and 0.96 for the cognitive subtotal. When evaluating construct validity, the motor subscale ..........
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
