Identifying the presence of cognitive impairment in patients admitted for inpatient rehabilitation is important as it may impact on their ability to participate in a rehabilitation program. The Folstein Mini Mental State Examination (MMSE) has been used by clinicians as a cognitive screening tool for its convenience, even though it is not sensitive, and often fails to detect cognitive impairmen...
In this letter we propose a Minimum Mean Square Error (MMSE) Channel Impulse Response (CIR) estimator-aided Decision Directed Channel Estimation (DDCE) method, which is suitable for employment in both OFDM and MC-CDMA systems. Firstly, we outline the difficulty associated with the employment of the Least Squares (LS) approach to the problem of a posteriori Frequency Domain Channel Transfer Func...
This paper presents a general structure for Minimum Mean Square Error (MMSE) equalizers from which we can derive instances such as the: two proposed Linear Equalizers with Extrinsic Feedback (LE-EF), Linear Equalizer (LE) and Decision Feedback Equalizer (DFE). The Extrinsic Information Transfer (EXIT) chart was used to analyze the two proposed MMSE LE-EF receivers and their characteristics was ...
UNLABELLED We describe a three-year experience with patients with dementia. METHOD clinical, cognitive and functional evaluation was performed by a multidisciplinary team for persons above 60 years. Mortality was assessed after three years. RESULTS Mini-Mental State Examination (MMSE) (n=2,074) was 15.7 (8.4). Male patients MMSE (n=758) was 15.6 (8.3) and female's (n=1315) was 15.8 (8.3). I...
Cognitive symptoms are common in patients with congestive heart failure (CHF) and are usually attributed to low cerebral blood flow. In the present study, we aimed to evaluate global cognitive function (Mini Mental State Exam MMSE) in relation to both cardiac function (evaluated by echocardiogram) and cerebrovascular hemodynamics (evaluated by transcranial Doppler TCD) in CHF patients. In 83 pa...
در طراحی سیستم های کنترل با فیدبک با فرض کنترل پذیری کامل حالت و انتخاب مناسب بهره فیدبک، قطب های حلقه بسته سیستم در مکان های موردنظر جایابی می شوند. در حالت کلی لازم است که کلیه متغیرهای حالت برای فیدبک در دسترس باشند در بسیاری از کاربردهای واقعی اندازه گیری تمامی متغیرهای حالت امکان پذیر و یا ازنظر اقتصادی مقرون به صرفه نیست. در مواردی از این قبیل نمی¬توان به تمام متغیرهای حالت دسترسی پیدا کر...
We examine codes, over the additive Gaussian noise channel, designed for for reliable communication at some specific signal-to-noise ratio (snr) and constrained by the permitted MMSE at some lower snr. We show that the maximum possible rate is the one attained by superposition codebooks. Moreover, the MMSE function of codes attaining this maximum rate under the MMSE constraint is completely def...
امروزه درایوهای الکتریکی ac به طور گسترده در سیستم های از قبیل پمپ ها ، فن ها و.... مورد استفاده قرار می گیرد. در گذشته از روشهای مرسوم مانند کنترل اسکالر جهت کنترل موتور القایی استفاده می شد. کنترل مستقیم گشتاور باعث افزایش بازده ماشین القایی در صنعت شده است. در سال های اخیر استفاده از روش کنترل مستقیم گشتاور به همراه مبدل ماتریسی مورد توجه محققان قرار دارد. در این پایان نامه به بررسی روش کنت...
PURPOSE To determine how the omission of whole brain radiotherapy (WBRT) affects the neurocognitive function of patients with one to four brain metastases who have been treated with stereotactic radiosurgery (SRS). METHODS AND MATERIALS In a prospective randomized trial between WBRT+SRS and SRS alone for patients with one to four brain metastases, we assessed the neurocognitive function using...
Introduction: Reduction of renal function in elderly is associated with decreased cognitive function, especially in the fields of general cognitive ability, abstract reasoning, and verbal memory. Recognition of cognitive impairments can be helped by rehabilitation interventions for the patient and his family. The aim of present study was to compare MoCA, MMSE and AMTs questionnaires in diagnosi...
