زمینه و هدف: در شهرهای بزرگ (کلان شهرها) مهم ترین عوامل ایجاد آلودگی صوتی سیستم حمل و نقل، کاربری­های شهری از­جمله صنایع­سنگین، کارگاه­ها و مشاغل صدا­ساز می­باشد. در شهر تهران وجود کارگاه­های پراکنده صنعتی در سطح شهر نظیر نجاری، تراش­کاری، صاف­کاری و آهن­گری در مجاورت مناطق مسکونی، آموزشی و بهداشتی - درمانی می­تواند بر میزان آلودگی صدا تاثیر گذاشته و آن را افزایش دهد. روش بررسی: برای آگاهی از ...

سابقه و هدف: در بخش های مراقبت ویژه نوزادان (NICU) صداهایی با شدت ها و فرکانس های متفاوت از منابع مختلف تولید می شود. این صداها ممکن است تغییرات فیزیولوژیک ناخوشایندی را در نوزادان بوجود آورند. لذا آکادمی اطفال آمریکا توصیه می کند که متوسط شدت صوت در زمان بیداری حدود 45 دسی بل و در ساعات خواب شبانه نوزادان حدود 35 دسی بل باشد. با هدف تعیین میزان شدت صوت موجود در NICU مطالعه زیر در سال 1384 بعمل...

Introduction and Purpose: Noise pollution is one of the important environmental problems that has been on a growing trend in the recent years. This study was conducted to evaluate the level of noise pollution in Omidiyeh city, Iran. Methods: Testo 815 sound level meter was employed to quantify the sound pressure level (SPL). The measurements were conducted during 7-9 am, 12- 14 am, and 19-21 pm...

Self-paced learning (SPL) is a recently raised methodology designed through simulating the learning principle of humans/animals. A variety of SPL realization schemes have been designed for different computer vision and pattern recognition tasks, and empirically substantiated to be effective in these applications. However, the investigation on its theoretical insight is still a blank. To this is...

Unit testing is an attractive quality management tool in the software development process, however, practical obstacles make it difficult to use unit tests for performance testing. We present Stochastic Performance Logic, a formalism for expressing performance requirements, together with interpretations that facilitate performance evaluation in the unit test context. The formalism and the inter...

This is the first report of sphingosine 1-phosphate lyase (SPL) protein expression and enzymatic activity in human neoplasm. This enzyme drives irreversible degradation of sphingosine 1-phosphate (S1P), a bioactive lipid associatedwith resistance to therapeutics in various cancers, including prostate adenocarcinoma. In fresh human prostatectomy specimens, a remarkable decrease in SPL enzymatic ...

Measures of the sound pressure level (SPL) near the eardrum were determined at discrete frequencies between 500 and 4000 Hz on 50 ears using TDH-39P and ER-3A earphones with the attenuator of an audiometer fixed at 90 dB HL. Results revealed significant differences in the measured SPL between the two earphones at all test frequencies. Results also revealed large intersubject differences in the ...

In this paper, synthetic jet actuators (SJAs) with three different orifice shapes (circular, square, and slot) the same cross-section area were investigated. The SJA efficiency (SJ) Reynolds number calculated based on time-mean reaction force measurement. momentum velocity was measured hot-wire anemometry additionally, sound pressure level (SPL) measured. equal maximally to 5.3% for each shape,...

Software Product Line (SPL) is a software engineering paradigm that is inspired by the concept of reusability of common features, formulated for different software products. Complete testing of all software products in SPL is known to be unfeasible. This is due to the very large number of possible products that can be produced or configured using a combination of features in the SPL. Pairwise T...

Thermodynamics problems for the single-phase-lagging (SPL) model have not been much studied. In this paper, the violation of the second law of thermodynamics by the SPL model is studied from two perspectives, which are the negative entropy production rate and breaking equilibrium spontaneously. The methods for the SPL model to avoid the negative entropy production rate are proposed, which are e...
