Economic size of farms and adjustments of the total factor productivity to the business cycle in Polish agriculture
agriculture business cycle CAP input-output analysis TFP
2017/2/21
The article presents an approach to changes in the total factor productivity (TFP) which differs from that generally found in the literature. Changes are calculated in the real terms using the detaile...
Factors affecting farm size on the European level and the national level of the Czech Republic
agricultural holding size farm structure land consolidation land management rural development
2017/2/21
Extreme differences in agricultural holding size, existing not only among the countries within the EU as a whole but also within the farm structures of the individual countries, create a considerable ...
Changes in skeletal muscle and organ size after a weight-loss intervention in overweight and obese type 2 diabetic patients
type 2 diabetes magnetic resonance imaging body composition skeletal muscle organ mass weight loss Look AHEAD trial
2018/11/12
Background: The effect of a weight-loss intervention on the masses of lean tissues and organs in humans is not well known.Objective: We studied the effects of a diet and exercise weight-loss intervent...
Consequences of supports to the economic situation of farms with respect to their size
agriculture enterprises economic situation fixed effect model subsidies
2016/8/1
The article is dealing with an issue of subsidies granted to agricultural enterprises arising from the Common Agricultural Policy (CAP). The aim of the paper is to quantify the effects of the individu...
Dairy farm profit according to the herd size,milk yield,and number of cows per worker
cows profit production reproduction
2016/6/3
The study evaluates the associations of the farm herd size (HERD), the milk yield (MY, kg/cow per year), and cows per worker (CW) with the production, reproduction, and economic traits in 60 commercia...
Sizing the Horizon: The Effects of Chart Size and Layering on the Graphical Perception of Time Series Visualizations
Visualization graphical perception time series line charts, horizon graphs
2016/5/24
We investigate techniques for visualizing time series data
and evaluate their effect in value comparison tasks. We
compare line charts with horizon graphs—a space-efficient

Properties of Census Dual System Population Size Estimators
Capture-recapture Correlation Bias Erroneous enumeration Kernel smooth- ing Model bias
2016/1/19
We evaluate three population size estimators, including the post-stratification and lo-gistic regression estimators which has been or will be implemented in the US Census dual system surveys. Conditio...
Laser Footprint Size and Pointing Precision Analysis for LIDAR Systems
LiDAR Data Accuracy Analysis Laser scanning
2015/11/20
Laser footprint size and beam divergence angle tuning was found to affect LiDAR data accuracy and measurement precision because of beam axis shifting. The laser beam divergence angle is generally tuna...
Comparison of Radiological Findings of Chest X-Ray With Echocardiography in Determination of the Heart Size
Echocardiography Thoracic Radiography Enlarged Heart Cardiomegaly
2015/10/16
Background: Heart size is an important and effective parameter in chest X-ray (CXR) interpretation. Studies indicate that, especially in middle-aged men, increased cardiothoracic ratio (CTR) is associ...

How Small Should Pixel Size Be?
Signal-to-Noise Ratio(SNR) Dynamic Range(DR) Modulation Transfer Function(MTF)
2015/8/17
Pixel design is a key part of image sensor design. After deciding on pixel architecture, a fundamental tradeoff is made to select pixel size. A small pixel size is desirable because it results in a sm...
Optimal Throughput-Delay Scaling in Wireless Networks–Part II:Constant-Size Packets
Throughput-Delay Scaling Wireless Networks Constant-Size Packets
2015/8/12
In Part I we characterized the optimal throughput-delay trade-off in static wireless networks as D(n) = Θ(nT(n)), where D(n) and T(n) are the average packet delay and throughput in a network of n node...
Hierarchical Identity Based Encryption with Constant Size Ciphertext
Constant Size Ciphertext Based Encryption
2015/8/5
We present a Hierarchical Identity Based Encryption (HIBE) system where the ciphertext consists of just three group elements and decryption requires only two bilinear map computations, independent of ...
A traitor tracing system enables a publisher to trace a pirate decryption box to one of the secret keys used to create the box. We present the first traitor tracing system where ciphertext size is "co...
