Ảnh Low-key là gì? Kỹ thuật Low-key (sắc nặng) là phong cách nhiếp ảnh sử dụng tông màu đen làm chủ đạo, phần sáng chỉ chiếm một diện tích nhỏ nhưng lại tạo nên “nét vẽ” cho chủ thể. Trong Low-key, độ tương phản là ngôn ngữ tạo hình và cũng là cái "chất" thể hiện sự khác biệt của kỹ thuật này....
Không gì có thể tác động đến thị trường mạnh mẽ bằng giá cả, nhất là khi giá đó lại rất, rất rẻ. Sự xuất hiện của khái niệm low-cost trong lĩnh vực vận chuyển hàng không đã làm thay đổi ngành công nghiệp này đến mức độ không còn nhận ra, và việc “phân phát” phiếu giảm giá với số lượng lớn đã thu hút hàng triệu người tiêu dùng. Hiện nay, chiến lược low-cost bắt đầu thâm nhập vào những mảng mới dịch vụ mới.
On 23 March 1989, electrochemists M. Fleischmann and S. Pons claimed in a press conference at the University of Utah that they had achieved nuclear fusion in a tabletop chemistry experiment. Since then, evidence of fusion in what is now called low-energy nuclear reaction (LENR) research has grown only slightly stronger. Their hypothesis that a novel form of thermonuclear fusion was responsible for their experimental results is still unproved.
Low key lighting dùng để chỉ một phong cách của nhiếp ảnh, trong đó sử dụng tông màu đen là chủ đạo để tạo ra một hình ảnh ấn tượng. Khi chụp trong điều kiện ánh sáng mạnh, sự tương quan trở nên yếu đi, và ngược lại, khi chụp trong điều kiện ánh sáng yếu, độ tương quan trở nên rõ nét để nổi bật chủ thể muốn chụp.
This book reports the latest development and trends in the low Re number
aerodynamics, transition from laminar to turbulence, unsteady low Reynolds number
flows, experimental studies, numerical transition modelling, control of low Re number
flows, and MAV wing aerodynamics. This book focuses particularly on: (1) a review
and brief information study on low Reynolds number flows and transition as an
introduction to low Re number aerodynamics (Chapter 1), (2) transition modelling
(Chapters 2-4), flow control (Chapters 5-7).
Low-density parity-check (LDPC) codes are forward error-correction codes,
first proposed in the 1962 PhD thesis of Gallager at MIT. At the time, their
incredible potential remained undiscovered due to the computational demands
of simulation in an era when vacumm tubes were only just being replaced by
the first transistors. They remained largely neglected for over 35 years. In the
mean time the field of forward error correction was dominated by highly structured
algebraic block and convolutional codes.
The Low Achievement Trap is an empirical study of student mathematics learning in Grade 6 classrooms that is unique in its focus on two school systems shaped by different political histories on either side of the Botswana-South Africa border. The study provides a detailed examination of the capacity of teachers - how they teach, how much they teach, and what they teach. Because of this wealth of detail, The Low Achievement Trap gives us much greater insight
Low-carbohydrate diets have been advocated for weight loss and to prevent obesity,
but the long-term safety of these diets has not been determined.
We evaluated data on 82,802 women in the Nurses’ Health Study who had completed
a validated food-frequency questionnaire. Data from the questionnaire were
used to calculate a low-carbohydrate-diet score, which was based on the percentage
of energy as carbohydrate, fat, and protein (a higher score reflects a higher intake
of fat and protein and a lower intake of carbohydrate).
Medicare's Prospective Payment System (PPS) includes an adjustment that provides additional payments to hospitals that serve a disproportionately large share of low-income patients. the principal rationale for this adjustment is that low-income patients are costlier to treat, controlling for DRG. Only a few studies have directly examined this issue, however. These studies differ both over whether ......
We present a novel method to improve word alignment quality and eventually the translation performance by producing and combining complementary word alignments for low-resource languages. Instead of focusing on the improvement of a single set of word alignments, we generate multiple sets of diversiﬁed alignments based on different motivations, such as linguistic knowledge, morphology and heuristics.
High-density lipoprotein (HDL) cholesterol levels are a strong inverse predictor of
cardiovascular events. However, it is not clear whether this association is maintained
at very low levels of low-density lipoprotein (LDL) cholesterol.
A post hoc analysis of the recently completed Treating to New Targets (TNT) study
assessed the predictive value of HDL cholesterol levels in 9770 patients.
With a view to launch a low carbon society in Taiwan by 2050, the Executive Yuan
ratified the Sustainable Energy Policy Guide in 2008. Taiwan is now committed to
reduce CO2 emission back to its 2005 level by 2020. Then, back to the 2000 level by
2025, and finally achieving 50% of 2000 level by 2050. In addition, the EPA abiding by
the Copenhagen Accord to summit Taiwanese NAMAs to the UNFCCC in 2010.
The implementation of active pixel based image sensors in CMOS technology is becoming increasingly important for producing imaging systems that can be manufactured with low cost, low power, simple interface, and with good image quality. The major obstacle in the design of CMOS imagers is Fixed Pattern Noise (FPN) and Signal-to-Noise-Ratio (SNR) of the video output.
Active Low-Pass Filter Design focuses on active low pass filter design using operational amplifiers. Low pass filters are commonly used to implement antialias filters in data acquisition systems. Design of second order filters is the main topic of consideration.
The association of neurodevelopmental handicaps and congenital anomalies with low birthweight has been well established; low birth-weight infants also may be susceptible to a wide range of other conditions, such as lower respiratory tract infections, learning disorders, behavior problems, and complications of neonatal inten...
