Repeatability and intermediate precision of a mass concentration calibration system

Abstract Many aerosol instruments require calibration to make accurate measurements. A centrifugal particle mass analyzer (CPMA) and aerosol electrometer can be used to calibrate aerosol instruments that measure mass concentration. To understand the sources of uncertainty in the calibration method, two CPMA-electrometer systems were tested to measure the repeatability and intermediate precision of the system, where the repeatability is the standard deviation of several measurements using the same system over a short period of time, and the intermediate precision is the standard deviation of several measurements using different instruments with different calibrations over a long period of time. It was found that the repeatability of the CPMA and the aerosol electrometer were both 0.8%, while the intermediate precision was 1.3% and 2.2%, respectively. The intermediate precision of the aerosol electrometers determined here compares well with a broader study by national metrology institutes which determined an intermediate precision of ∼1.7%. By propagation of uncertainty, it is expected that a CPMA-electrometer system would have repeatability of 1.1% and an intermediate precision of ∼2.1%. This compares favorably to thermal-optical analysis methods which aim to measure black carbon mass concentrations for instrument calibration, which have a repeatability in the range of 8.5–20% and reproducibility in the range of 20–26% for elemental carbon. Thus, the CPMA-electrometer method may be a good alternative to existing instrument calibration procedures. Copyright © 2019 American Association for Aerosol Research
Extreme Programming Used to Establish the Culture of a High Performance Team: A Management Case Study

Management can often be frustrated by the inability of software development teams to respond quickly to changes in requirements. The standard explanation is that the key developers on the team are too busy with critical path tasks. A more accurate statement would be that the so-called software development team is not actually a team but merely a group of individuals related by an organizational chart. This paper recounts one development organization's transformation from organizational chart to a high performance team using the practices of Extreme Programming.
Development and Optimization of an Alternative Methodology for Detection of Milk Adulteration by Water

This paper presents a process which allows the determination of milk adulteration by water. Considering the limitations of the reference method (cryoscopy), the proposed methodology matches electrical conductivity and cryoscopy index measurements. Based on statistical procedures, a linear descriptive model is achieved to quantify adulteration of milk with water. It is also shown that electrical conductivity measurements allow the detection of adulteration with water and sodium chloride.
Extending web applications to mobile platforms: a software engineering view

4 Abstract The purpose of this master thesis is to investigate the problems and solutions for a company who wants to expand their applications onto mobiles. It is important for the company if they can find the faster way to develop the same system onto mobile apps, what artifacts can be used in common and what can be reused. Even smartphones have ability to work almost like PC but they also have many limitations such as screen size, limited resources like RAM, disk, and battery. How can we compromise the full data context with those limitations? In this master thesis, we have studied all perspectives in the software engineering area and come up with problems and solutions through the real implementation of mobile apps. We have learned that a project plan and organization involvement at the beginning is crucial because the decision on the target market, software architecture, offline/ online necessity affects a lot later on in the implementation phase. We have found out that a large extent on the reuse is based on the software architecture and design pattern. The tradeoff between using the same design pattern and different mobile frameworks’ best fits design patterns is a one interesting future study topic. A testing coverage is also one topic that we have found out needed because a mobile app needs more considerations than a traditional application.
High Rate User Ka-Band Phased Array Antenna Test Results

The High Rate User Phased Array Antenna (HRUPAA) is a Ka-Band planar phased array designed by the Harris Corporation for the NASA Goddard Space Flight Center. The HRUPAA permits a satellite to downlink data either to a ground station or through the Tracking and Data Relay Satellite System (TDRSS). The HRUPAA is scanned electronically by ground station / user satellite command over a 120 degree cone angle. The phased array has the advantage of not imparting attitude disturbances to the user spacecraft. The 288-element transmit-only array has distributed RF amplifiers integrated behind each of the printed patch antenna elements. The array has 33 dBW EIRP and is left-hand circularly polarized. An engineering model of a partially populated array has been developed and delivered to NASA Goddard Space Flight Center. This report deals with the testing of the engineering model at the Goddard Antenna Range near-field and compact range facilities. The antenna specifications are described first, followed by the test plan and test results.
A Cross Sectional Study on Smartphone Addiction among Students in Ayapakkam, Thiruvallur District, Tamil Nadu, 2018

Background: India stands second for Smartphone usage in the world according to “global market” report. Smartphone addiction affects the younger generations to a greater extent. The objectives of the study was to estimate the proportion of students of age 18–24 years who were addictive to their Smartphone, to estimate the average time spent by them, to find the main reasons for usage and also to find the association between Smartphone usages and sleep quality of the students. Method: A cross sectional community based study was done in Ayapakkam, Thiruvallur district, Tamil Nadu. Two stage cluster sampling methodology was employed for selecting a random sample of 139 students. In the first stage 4 clusters were selected based on the more populous clusters and in the second stage a minimum of 35 students were interviewed from each of the selected cluster. Smartphone Addiction Scale (SAS) and Pittsburgh Sleep Quality Index(PSQI) were the tools used for assessing the association of Smartphone addiction and sleep quality of the students. Data was collected using tablet and Epicollect 5 web application. Descriptive statistics, Chi-Square for association and t-test to determine whether there exists significant difference between the means of two groups was assessed. Results: The proportion of students who were addict to their Smartphone was 52.7% and among them it was more in males (66.2%). On an average 6.42 hours/day was spent on their Smartphone. The major reason behind using their Smartphone was for communication (5.03 hours/day). The association between SAS and PSQI were found to be highly significant ( χ 2 = 11.035, p-value < 0.01). Conclusions: It is an alarming sign that students are prone to addiction to Smartphone. The younger generation must be brought awareness about their Smartphone addiction and heath impact they are prone in due course of time.

Relationship of Common Variants in miR-27a-3p Gene with Susceptibility and Prognosis of Oral Cancer

Background: miR-27a-3p has been found dysexpressed in various cancers. The aim of the present study was to clarify the prognostic value of miR-27a-3p in patients with oral cancer.Methods: We used quantitative real-time polymerase chain reaction (qRT-PCR) assay to detect the expression of miR-27a-3p in the tissue of oral cancer and adjacent normal specimens. The association of miR-27a-3p with clinicopathological characteristics was analyzed via the Chi-square test. Kaplan-Meier survival and Cox regression analysis were performed to evaluate the prognostic value of miR-27a-3p in oral cancer patients.Results: The down-regulated expression of miR-27a-3p was found in oral cancer tissues compared with the matched noncancerous samples (P<0.05). And its expression was influenced by TNM stage (P=0.032), T stage (P=0.014) and lymph node metastasis (P=0.025). Kaplan–Meier analysis result showed that the decreased level of miR-27a-3p expression was associated with a poor overall survival of oral cancer patients. Additionally, multivariate cox regression analysis revealed that the low expression of miR-27a-3p was an independent prognostic maker in oral cancer patients (HR=0.462, 95% CI=0.223-0.957, P=0.038). Conclusions: Taken together, the expression pattern of miR-27a-3p was decreased in oral cancer tissues. The decreased expression of miR-27a-3p was a potential prognostic biomarker in patients with oral cancer.

A Visualization Method of Browsing History to Support Reflection on Information Gathering Behavior

Browsing history is the data that records the information gathering behavior through the Internet in many situations in our lives, and is a part of the lifelog that records and stores personal experiences. This study aims to utilize the browsing history as a record of daily life, focusing on self-reﬂection, which is the process of analyzing past actions to gain self-understanding and behavior improvement. The proposed system supports the recall of contents of browsed web pages by analyzing the topics in the browsing history, and the recall of the background of browsing by visualizing the browsing history based on the topics and the browsing time series. In order to investigate the eﬀectiveness of the proposed system, we conducted an evaluation using actual browsing histories as input. The results showed that the system provided suﬃcient support for content recall when the feature words of the web pages were successfully extracted. As for the background recall, the visualization of the browsing history using the combination of the topics and the time series helped the subject recall the thoughts and events of the time. Also the proposed system provided useful reﬂections on the information gathering behavior and life at that time.
Performance comparison of wind park configurations

In this report, layouts of various large-scale wind parks, both AC as well as DC, are investigated. Loss modelling of the wind park components as well as calculations of the energy capture of the turbines using various electrical systems are performed, and the energy production cost of the various park configurations is determined. It was found that from an energy capture point of view, the difference in energy production between various wind turbine systems is very small. In addition, a study of the suitability of various DC/DC-converters is made. Three DC/DC-converters, Boost, Full Bridge and Full Bridge Isolated Boost, are found to be interesting candidates as the "transformer" component in potential DC-based wind parks. Of all the investigated wind park configurations, the wind park with the series connected DC wind turbines seems to have the best potential to give the lowest energy production cost, if the transmission distance is longer then 10-20km.
Stock Dividend Ex-Day Abnormal Return

This study examines the impact of the ex-day of stock dividend on stock return and volume on Borsa Istanbul stock exchange. The data covers 1,220 stock dividends associated with 305 companies over the period 1997-2018. A positive abnormal return and volume is seen around the ex-day of stock dividend. The cumulative average excess return over market return starts to significantly rise ten days before ex-day and reaches its highest level on the ex-day before falling back in the days following. Our findings show that abnormal return around ex-day is strongly associated with stock dividend pay-out ratio, asset size and a company’s market value. The share of listed companies with higher stock dividend pay-out ratio or lower asset size or lower market capitalization, can generate respectively 5.97%, 6.08% and 5.88% abnormal return over market index return.
Big brother in the big apple [Surveillance]

New York and the rest of the USA are catching up with Britain in public surveillance technology. Due to major security concerns in America, the US is catching up to its British ally: about 3,000 cameras are being installed as part of the Lower Manhattan Security Initiative, a trend echoed in many other American cities including Dallas, Phoenix, Baltimore, New Orleans and Los Angeles. Also, New York City's Metropolitan Transit Authority (MTA) is in the midst of furthering a high-tech security upgrade, which began in 2006. Surveillance continues and the use of digital images - including such seemingly innocuous ones as mobile phone snapshots - proliferates. The technology that some surveillance marketers and integrators are offering are discussed.

Control of multiple Aerial Vehicles in a Mixed-Initiative Environment

Unmanned Aerial Vehicles have been adopted in large scale for various military and civilians missions over the air, sea, space and the ground. Their massive use are mainly justified by the ability to avoid placing human life in harm’s. Also the lack of onboard operator enables significant weight savings regarding life support equipment, resulting the lower cost and weight, increasing endurance. The continuous increase of autonomous capabilities of aerial vehicles allows their use in a set of teams, creating a new operational paradigm. Such operation scenario is the use of small unmanned vehicles over a urban area, enabling the tracking of targets from a close range impossible to archive with manned large scale vehicles such as helicopters. The system presented is being designed to perform persistence intelligence, reconnaissance and surveillance for targets in a urban environment. The use of low cost systems, low-altitude, short endurance UAV’s can provide high resolution data to ground personal while maintaining a low operation and logistics cost. These UAV’s can be deployed quickly and easily over several combination (hand, catapult small track). One of the main disadvantages is their limited sensor capabilities and endurance time. However, this can be overcome by proper sharing of relevant information among the other team of vehicles. The objective of this thesis is to study and develop cooperation techniques among team of decentralized UAV’s in order to perform tasks of persistence surveillance over a urban dense area with strong occlusions. To achieve that, several tracking and cooperation techniques were studied in order to extract some useful ideas and adopt then on the project. Tanking in account the final objective of this thesis, a simulation enviroments was developed in order to replicate the most relevant conditions in the scenario of operation, controllers and path planning algorithms to drive the vehicles, distributed tracking system with multi-target and multi-observation capabilities and a auction mechanism for the cooperation among the UAV’s
An Investigation and Evaluation of Risk Assessment Methods in Information systems

As technology develops and information society becomes more and more popular, information systems are involved in almost every aspect of people’s life. One recent example is the uprising concept “Internet of things” that almost tries to solve everything within network and technology. With the convenience and benefits technology brings to us, risks also follow and threaten the environment we are enjoying. Wikileaks, NSA and Snowden, etc, those big dramas should make us more alert of those security issues and risks that we might encounter with information systems. In order to foresee the potential risks, predict the consequences and prepare the possible countermeasures, an exhaustive review into the risk assessment mechanisms we have today is needed. There are mainly three existing risk assessment methods: quantitative approach, qualitative approach and combined approach. This thesis makes a survey of the existing risk assessment methods (8 management tools, 2 technical tools, and 9 basic methods). It performs a comprehensive analysis and comparison between the different approaches, this involve reconstructing and grouping the surveyed methods according to their important factors, processing methods, and application environment. The weaknesses and benefits of the surveyed methods are discussed, and a risk assessment classification framework is proposed, dealing with risk assessment decision making or other related scenarios. Further, a systematic method is presented as an elaborate solution in the risk assessment field. Finally, the result of the study is considered in the broad picture of the risk assessment process design and implementation.
Linkage disequilibrium score regression distinguishes associations between lean body mass and blood plasma proteome

Background: Lean body mass (LBM) is an essential component of body composition. Recent studies observed associations between altered plasma proteins and LBM. This study aims to explore the potential genetic relationships between LBM and plasma proteome. Methods: The genome-wide association study (GWAS) summary data of LBM were driven from ~85,000 individuals of European descent. The GWAS summary data of 3,622 plasma proteins were obtained from 3,301 healthy participants. Linkage disequilibrium score regression (LDSC) analysis were conducted to evaluate the potential genetic correlation between each plasma protein and LBM using the GWAS summary statistics. Results: LDSC scan identified multiple plasma proteins for LBM, such as stabilin-1(coefficient=-0.4583, P value=0.0253) and inter-alpha-trypsin inhibitor heavy chain H1 (coefficient=-0.1716, P value=0.0314) for append LBM, and glyceraldehyde-3-phosphate dehydrogenase (coefficient=0.5997, P value=0.0315) and immunoglobulin lambda-like polypeptide 1(coefficient=0.35, P value=0.0334) for whole LBM. We also detected two common plasma proteins shared by append and whole LBM, including stabilin-1 and glyceraldehyde-3-phosphate dehydrogenase. Conclusions: This study provided an atlas of genetic correlations between LBM and plasma proteome, which are helpful for understanding the biological mechanism of LBM.
Simultaneous treatment with oil heat and densification on physical properties of Populus × Canadensis wood

Samples of wood from Populus × canadensis (9,5 % moisture) were treated with olive oil at 195 °C simultaneously with 15 % or 30 % compression densification, and the results were compared with samples subjected to oil heat treatment without densification, and control samples. The density of the treated samples increased by 18 %, 43 % and 1,5 % respectively, and barely changed over the six subsequent months stored inside the laboratory room (at approximately 65 % RH, 20 °C). This was due to the fact that the slight weight increment caused by the additional moisture content was offset by the increase in volume from the springback effect. When subjected to atmospheres with different relative humidities, the treated samples stabilised at the same time as the control samples, although the treated samples had a significantly lower moisture absorption than the control samples. It was also observed that the hygroscopic shrinkage in oil heat densification treatment samples was approximately half those of the control samples. The initial densification was partially lost as a result of springback: approximately 3 % in the first springback at a relative humidity of 65 % RH, and an additional 4 % in the second springback to a relative humidity of 85 % RH. Once this latter relative humidity had been attained, no new losses in densification were observed. The ageing of the oil used in the treatment caused a slight loss of densification in the densest samples.
HOLOGRAPHIC HEAD-UP DISPLAY

Abstract : A head-up display system as used by an aircraft commander must provide a simulation of the real-world exterior to his vehicle, and, at the same time, represent any change in his attitude with respect to a predetermined segment of this real world. In the particular case of an aircraft landing approach, one can characterize the pilot's view of the aircraft carrier and its subsequent variations into six degrees of freedom. The display must provide the view corresponding to the instantaneous values of these parameters and change as any one or more of the parameters change. This report describes the results of a continuation of the development work initiated in Phase I of the contract on displays of this type using sideband or carrier-frequency Fresnel holographic recorded images. The goals of Phase II were to study the various modes and techniques derived in Phase I and other possibilities, to select the approach that offered the best potential for use in Navy carrier-based aircraft and to build a laboratory model of this selected system. The selected approach uses a GaAs injection laser diode light source to interrogate a hologram of an aircraft carrier model. The real image from the hologram is optically relayed to a special IR vidicon, and the image is then transmitted electrically to a CRT monitor.
