EMBRACE: First experimental Results with the Initial 10% of a 10,000 Element Phased Array Radio Telescope

The Electronic Multi-beam Radio Astronomy Concept (EMBRACE) is the first full-scale prototype of an SKA phased array station. This single polarization demonstrator operates between 500 and 1500 MHz. The station that is currently being built at the site of the Westerbork Synthesis Radio Telescope, will ultimately consist of 144 tiles with 72 single polarization Vivaldi antennas each, giving a total of ∼ 104 elements. The station is equipped with a LOFAR station backend with 192 input channels, which can be exploited for real-time digital beam forming in 248 frequency channels of 195 kHz (∼ 48 MHz total bandwidth) and correlation in a single 195 kHz frequency channel. In this paper we present the results from a number of system validation measurements and the first fringes on an astronomical source, the sun. These initial measurements indicate a system temperature between 103 K and 117 K. These results corroborate the feasibility and applicability of phased array technology at frequencies below 1500 MHz. They also provide valuable insights for the aperture array verification program, the next step in aperture array development towards the SKA.
IT Training and Employability of Older Workers

This paper empirically analyzes the relationship between firm-provided IT training and the firm? s proportion of older workers. Using data from the ZEW ICT survey of the years 2004 and 2007, the results show that a firm? s IT intensity plays a crucial role: firms intensively using information technologies employ a significantly smaller proportion of older workers than firms that are less IT-intensive. However, higher participation rates of older workers in IT training are related to a larger proportion of older workers within firms. It turns out that this effect is of particular importance in firms that intensively use IT.
Application of Optimal Input Synthesis to Aircraft Parameter Identification

The Frequency Domain Input Synthesis procedure is used in identifying the stability and control derivatives of an aircraft. By using a frequency-domain approach, one can handle criteria that are not easily handled by the time-domain approaches. Numerical results are presented for optimal elevator deflections to estimate the longitudinal stability and control derivatives subject to root-mean square constraints on the input. The applicability of the steady state optimal inputs to finite duration flight testing is investigated. The steady state approximation of frequency-domain synthesis is good for data lengths greater than two time cycles for the short period mode of the aircraft longitudinal motions. Phase relationships between different frequency components become important for shorter data lengths. The frequency domain inputs are shown to be much better than the conventional doublet inputs.
Modelling of displacement ventilation and chilled ceiling systems using nodal models

Cooling and ventilation of office spaces by displacement ventilation and chilled ceiling panel systems is potentially more energy efficient than conventional air conditioning systems. Heat transfer in this type of system is characterised by the presence of vertical temperature gradients and significant radiant asymmetry. The room heat transfer models used in current building simulation methods do not allow adequate representation of this type of system due to their reliance on a single node to define the internal air temperature. The overall aim of the work described in the thesis has been to develop a model of this type of system that is suitable for use in annual building energy simulation. The model presented, is intermediate in complexity between a CFD numerical model and the current single air node models, having ten air nodes. The operating characteristics of displacement ventilation systems, used both with and without chilled ceiling panels, have been studied by making experimental measurements in a test chamber and by reference to published experimental data. Numerical calculations of the flow and temperature fields have been made with a coupled flow and radiant exchange CFD code. Steady state calculations have been made of displacement ventilation using a conjugate heat transfer method. Interesting oscillations in the flow and temperature field of displacement ventilation operating with a chilled ceiling have been found through adopting a fully transient calculation procedure. The thesis describes how the experimental and numerical data has been used to develop the structure and define the parameters of a simplified nodal model. The logical development of the model structure, from the most elementary model to one which is able to capture the effects of the temperature gradients and incomp1ete mixing of the air in the room is described. A method is also presented whereby the parameters of the model are found directly from the experimental data by solving the heat and mass balance equations of the nodal model. The parameters of the model have been generalised by analysing these calculations and by making use of established convection coefficient correlations. The performance of the model is demonstrated by firstly making comparisons of the experimental and numerical data under steady state conditions, and also by demonstrating that the model is able to reproduce the characteristics of displacement ventilation and chilled ceiling systems under different operating conditions.

Nonlinear propagation in water and its effect on NDT

In an attempt to reduce the uncertainties in quantitative ultrasonic C-scanning, it has been found that the effects of nonlinear propagation in water cannot be ignored. Nonlinear propagation has been studied for many years in the medical ultrasonic field and other areas of acoustics. However, the subject has not been addressed in relation to non-destructive testing (NDT) because conventional bandwidth-limited NDT equipment filters out the characteristic fingerprint—a distorted waveform. In many ultrasonic fields nonlinear propagation is not important because low amplitudes and short propagation distances are used. However, it has been found that several popular commercial flaw detectors can produce large waveform distortions in water at the standard frequencies and amplitudes used for C-scan inspections. The presence of this phenomenon explains why increasing the voltage to the transmitting transducer does not always result in a proportionate increase in the received signal—it is possible to saturate the .
Overshot waterwheel to power an olive oil mill in Nepal

Slow rotating waterwheels have been proposed as affordable sources of renewable energy in rural areas. The international cooperation project “Promotion of olive production and consumption in Nepal (MAE-FAO)”1 aims to improve farmer's income and food security in remote areas of Far Western Development Region in Nepal. One basic trait of the project is the application of suitable technologies – for example, simple equipment and processing facilities using renewable energy. The overshot waterwheel (OW) is able to serve a distinct field of operation where the mechanical power is small, the speed of the machinery is slow and minor regulations are required. In this project, the wheel powers an olive crusher turning at around 10 r.p.m. requiring mechanical power of 2.5 kW. The method used to make this machine, based on historical engineering textbooks, provides the groundwork necessary to make a simple OW, avoiding pitfall in the design and construction.

Differential Effects of AIDS and Chronic Human Immunodeficiency Virus Infection on Gray Matter Volume

Age, human immunodeficiency virus (HIV) infection, illicit drug use, and central nervous system (CNS) opportunistic infections can affect brain structure, with the striatum being particularly sensitive to HIV effects. Nevertheless, the impact of non-CNS AIDS-defining illness (ADI) on brain structure has been less investigated. We examined ADI and HIV effects on brain volume. In a cross-sectional study, including 95 virally suppressed seropositive and 84 demographically matched, seronegative participants, we examined serostatus and ADI effects. Cortical and subcortical gray matter volume (GMV) regions of interest were estimated with computational neuroanatomy techniques applied to high-resolution, T1-weighted magnetic resonance imaging data. Linear regression was used to model HIV serostatus and ADI effects on global and regional GMV, adjusting for age, sex, CD4 nadir, drug use, and total intracranial volume. While HIV serostatus was associated with lower striatal volume (B = −.59 [95% confidence interval {CI}, −1.08 to −.10]), co-occurring ADI was independently associated with lower striatal volume (B = −.73 [95% CI, −1.36 to −.09]). ADI was also associated with lower global (B = −19.35 [95% CI, −32.42 to −6.29]) and regional GMV. While HIV infection is associated with a localized effect on striatal structure, having a prior ADI is a strong predictor of smaller global and regional GMV. The lack of interaction between HIV serostatus or ADI with age suggests that chronic HIV infection and ADI have independent effects on brain structure, without associated accelerated lower volume with age. ADI history should be incorporated into statistical adjustments in HIV neuroimaging analysis. These findings also lend support to current HIV treatment guidelines urging prompt antiretroviral therapy initiation after HIV diagnosis.
Evaluation of combination rules for peak response calculation in three‐component seismic analysis

The responses, re, given by several multicomponent combination rules used in seismic codes for determining peak responses to three ground motion components are evaluated for elastic systems and compared with the critical response rcr; this is defined as the largest response for all possible incident angles of the seismic components and obtained by means of the CQC3‐rule when a principal seismic component is vertical, or the GCQC3‐rule when it departs from the vertical direction. The combination rules examined are the SRSS‐, 30%‐, 40%‐ and IBC‐rules, considering different alternatives for the design horizontal spectrum.
Aerodynamic Performance Predictions of a SA- 2 Missile Using Missile DATCOM

Abstract : This study reports an analysis of the aerodynamic performance characteristics of an SA-2 type missile conducted using empirical codes. The Missile and Space Intelligence Center (MSIC) supplied the missile geometry, which was incorporated into the MissileLab interface. The study evolved based on the geometry changes MSIC recommended. Results obtained using Missile DATCOM versions 7/07 and 8/08 are compared along with performance data provided by the project sponsor. These data varied from experimental to empirical, as well as those generated using Simulink modeling. Data comparisons were carried out for various Mach numbers and angles of attack. For the most part, excellent agreement was obtained, especially when Missile DATCOM 8/08 was used, for the overall axial force coefficient value at the conditions explored validating the approach used. Some comparisons also were generated for specific fin deflections conditions. Additionally, a Computational Fluid Dynamics model was included as part of the analysis, using ANSYS CFX, a compressible flow solver. With these results and the predictive tool, the in-house capability at the Naval Postgraduate School to generate such data for future missile designs has been successfully enhanced.
The Impact of the Campaign on the Results of Local Government Elections

In a recent article in this journal1 we reported the results of an experiment designed to investigate, amongst other things, the effect of canvassing and polling-day activity upon the results of local government elections. On the basis of our data we argued that thorough canvassing before polling day and ‘knocking up’ on the day produced an appreciable increase in turnout. We also showed that, in a situation in which only one party organized the election thoroughly, this party would benefit disproportionately from the higher turnout; that is, it would receive an increased share of the vote.
Nudge to budge - social marketing in restaurants : A pilot study in Sweden

The aim of this research was to conduct a pilot study to identify if increased written communication at restaurants would affect customer and staff awareness of the restaurant’s sustainability efforts. By using before-after questionnaires among employees and customers possible changes among the two stakeholder groups be recorded. As the restaurants had recently joined the new network Sustainable Restaurants in Sweden, the effect of this collaboration on their CSR efforts and communication was evaluated through semi-structured interviews with the restaurant representatives. Social marketing was the underlying theory for this study, with focus on opportunity and ability. The restaurants communication efforts were identified as nudges. The study showed that collaborating in order to start communicating can prove to be an effective support mechanism. Increased communication proved to have somewhat an effect on customer awareness and staff awareness. Increased awareness amongst all actors of the food chain is a necessary step for a sustainable future.
Impression management : presentation formats in annual and stand-alone reports of UK FTSE 100 companies 2000-2005

This study examines 446 reports (223 annual reports and 223 stand-alone reports) of 46 FTSE100 companies for 2000-2005 inclusive. The selected companies are those that produced stand-alone reports in the form of a hardcopy for a minimum of three consecutive years ended 2005. This study analysed the total pages of the reports and the results show that the length of annual reports and stand-alone reports has increased over the years. The analyses of photographs, graphs and tables presented in those two types of reports show that tables and photographs are the most popular presentation format in the annual reports and stand-alone reports, respectively. Also, this study found that graphs and tables are the least popular presentation format in annual reports and stand-alone reports, respectively. There are more photographs of men, rather than photographs of women, presented in these two types of reports. Based on Signalling Theory, the companies, via photograph presentations, are argued to communicate a signal of power, rationality, emotional stability, aggressiveness, self-reliance, objectivity, and vigour, which attributes are commonly associated with men. Also, there are more, rather than less, portrait photographs presented in annual reports than in stand-alone reports to convince the readers of the truthful of information that the companies are presenting. Further, the companies are found to have used photograph presentations for impression management by way of presenting more images of humans at a workplace, rather than humans not at a workplace, in photographs presented in annual reports and stand-alone reports. Impression management also was detected on the presentation of graphs, tables and texts presented in stand-alone reports. Overall, size, activity, and listing status, but not performance, have been found to influence to a certain extent, on the number of photographs, graphs and tables presented in annual reports and stand alone reports.
Herbicide Efficacy in Seeded Rice with Different Methods under Wet and Dry Conditions

Field experiment was conducted at CCS HAU College of Agriculture Farm, Kaul, Haryana during kharif 2005 and 2006 to find out effective and viable system of controlling complex flora of weeds in direct seeded rice. Among different herbicidal treatments, pendimethalin at 1.5 kg/ha (PE) and cyhalofop butyl at 90 g/ha controlled Echinocloa very effectively but failed to check Cyperus, whereas pretilachlor+safener at 0.5 kg/ha provided excellent control of Cyperus. The grain yield was almost similar under the treatment of pendimethalin at 1.5 kg/ha fb HW at 30 DAS in all the sowing methods. Under wet seeding methods, pre-emergence application of pretilachlor+safener resulted in significantly higher grain yield of rice, whereas under dry seeding methods higher grain yield was recorded in the treatment of pre-emergence application of pendimethalin.
VCO based multi-stage noise shaping ADC

A way to combine several analogue-to-digital converters (ADCs) based on voltage-controlled oscillators (VCOs) to implement a multi-stage noise shaper (MASH) is proposed. By means of a simple digital circuit, the phase quantisation error in one stage is extracted as a pulsed signal. Then, this pulsed signal modulates the VCO in the next stage. First, the equations that describe the system are discussed and then a hardware implementation suitable for low power applications is proposed. The proposed implementation circuit also desensitises the ADC from the VCO nonlinearity by precoding the input signal using a pulse width modulation modulator.
Public support for different movements to reshape American policing is contingent on the perceived implications for crime and public safety

Recent high-profile cases of police violence against Black civilians have brought renewed attention to longstanding questions of racial bias and unfairness in American policing. Are contemporary movements to reform, defund, or abolish the police likely to succeed? Answering this question, in part, requires understanding how the mass public interprets these efforts, and what they believe each seeks to accomplish. This note presents novel survey and experimental evidence to inform theoretical and empirical research in this domain. We find strong support for police reform, but efforts to defund or abolish the police generate opposition both in terms of slogan (e.g., “defunding the police”) and substance (e.g., “reduce police budgets and reallocate funding to social services”). We do not find evidence that these differences can be explained by differing beliefs about each movement’s association with violent protest, racial makeup, or specific programmatic changes targeting police administration or officer behavior. Movements to defund and abolish the police are, however, perceived to seek reduced involvement of police in traditional crime control roles and cuts in police numbers. On average, the public opposes the former and is fearful of the latter. These findings suggest that public support for changes to American policing is contingent on the perceived implications for crime and public safety.
Initial response of underplanted yellow poplar and cherrybark oak seedlings to four levels of mechanical midstory removal

Midstory removal has been suggested as a possible enhancement strategy to develop seedling pools in stands lacking vigorous advanced oak (Quercus spp.) reproduction. However, for successful implementation, silviculturists must understand the differential growth responses of oak and its competitors to conditions created by midstory removal. To further quantify the competitive dynamics between cherrybark oak (Q. pagoda Raf.) and yellow-poplar (Liriodendron tulipifera L.), this study was designed to assess the initial height growth responses of these species to four levels of midstory removal and to understory vegetation control. The study was installed within a riparian corridor located in western Georgia, and treatments were completed in the fall of 2003. One-year data suggests cherrybark oak height increment was not significantly increased by any level of midstory removal. In contrast, yellow-poplar growth was significantly greater in the removal treatments and was highest under full midstory removal. Results also show that the height growth of cherrybark oak was significantly higher and yellow-poplar was significantly lower within understory control treatment. Overall, data suggest that underplanted yellowpoplar may have initial height growth advantage over cherrybark oak following midstory removal.
