Lamb survival traits in Coopworth sheep selected for high or low backfat depth

Consumer preferences for lean healthy meat have driven genetic selection for leanness in the terminal sire and dual purpose sheep industries over the last 20 years. The Invermay Coopworth lean and fat selection lines were established in 1980 to study the effects of selection for live weight adjusted leanness on carcass traits, and the correlated responses in other traits. This paper reports the findings of two year’s data on lamb survival and performance in the lean and fat selection lines. Records were collected from 817 lambs comprising 325, 337 and 155 from the fat, lean, and a randombred control line, respectively. Neo-natal mortality was not significantly different between the three lines, with approximate ly 93% of lambs born surviving until tagging. Lamb survival from tagging until weaning differed significantly between the selection lines (P<0.05), with fat line animals having 10.9% better lamb survival than lean line animals (95.5 verses 84.6%), after adjusting for differences in year, birth weight, birth rank, skin thickness, wool length, age of dam, mothering ability and ewe udder volume. Fat line lambs were 0.9 ± 0.1kg (mean ± SEM) lighter than lean line animals, with control line animals intermediate. Udder volume (as measured by water displacement) did not differ between the three lines. Mothering ability (as measured by distance from ewe to the new born lamb during handling in the field) did not differ significantly between the lean and fat lines. Fat line lambs had thicker skins than lean line lambs at the same birth weight (P<0.01), but had no difference in wool length. The differences in lamb mortality between the lean and fat lines cannot be fully explained by differences in birth weight, indicating some physiological difference between the lines affecting survival.
Direct power control of doubly fed induction generator without phase-locked loop in synchronous reference frame during frequency variations

This study presents a direct power control strategy for a grid-connected doubly fed induction generator (DFIG) without phase-locked loop (PLL) in a synchronous reference frame. In the proposed control system, a virtual phase angle, produced by a fixed angular speed, is used to replace the actual one of the network voltage for synchronous coordinate transformations, thus, PLL can be eliminated. The steady-state and dynamic behaviours of DFIG active and reactive powers are analysed with the potential grid frequency variations. It is found that the natural components of the flux linkages are the root cause of power and torque pulsations during the transient frequency variations. Thus, an auxiliary demagnetising current control scheme is proposed and designed to damp the natural flux linkages caused by the transient frequency variations. Then, based on the mathematic model, the control system performance is theoretically analysed. Finally, the simulation and experimental results are provided to demonstrate that the developed control system is adaptive to frequency deviations and achieve a decoupling control of both active and reactive powers.
Corrigendum

Since 2000, the Black Hills National Forest (BHNF) has experienced several disturbances that have reduced standing live sawtirnber volume which will affect future harvest levels. To evaluate options concerning the future timber management program, we conducted a quantitative analysis to determine how mortality from these disturbances and potential growth rates will impact short-, mid-, and long-term sustainable sawtimber harvest levels of ponderosa pine (Pinus ponderosa var. scopulorum Dougl. ex Laws.). In 2019, there was 5,995,428 CCF (hundreds of cubic feet) standing live ponderosa pine sawtimber within the suitable timberlands. The current harvest level in the BHNF Forest Plan of 181,000 CCF/yr is not a sustainable option. Over the next several decades, if mortality rates stay below 1.04%, harvest levels of 72,400 and 90,500 CCF/yr appear to be sustainable if all suitable timberlands are available for harvest. History shows that allowing the forest to recover after large disturbances provides opportunities to adjust future harvest levels. Also, tending of young forests can promote recovery and produce sawtimber volume more quickly.
Developing a Customer-focused Culture in the Speculative House-building Industry

The UK house-building industry has often been criticized for the quality of its products. Its business drivers are less focused on the needs of customers compared with much of the manufacturing sector. A recent survey revealed considerable dissatisfaction among buyers of newly built homes, particularly with the after-sales service provided by vendors. However, this cannot be viewed in isolation from the general business culture that prevails. This paper examines existing practices in the industry that act as barriers to a change in culture and discusses the steps that are being taken in a major house-building company to overcome them. Work on implementation of the policy through a balanced set of performance measures as the drivers for change and a participative programme for its deployment is presented. The objective is the development of a customer-focused culture that views service and product quality as contributing to future sales and profitability, instead of simply in terms of costs.
A CPW‐FED planar dual band‐notched ultra‐wideband antenna by etching an S‐shaped SIR slot on the feed line

A novel planar ultra‐wideband antenna with 3.6/5.5 GHz dual band‐notched characteristics is proposed in this article. By etching an S‐shaped step‐impedance resonator slot on the feed line, antenna with dual band‐stopped filtering properties in the world interoperability for microwave access/wireless local‐area network bands are achieved. The proposed antenna consists of a beveled rectangular metal patch and a 50 Ω coplanar waveguide transmission line. The antenna is successfully designed, simulated, and measured, which exhibits broadband impedance matching and stable radiation patterns. The mechanism of this dual band‐notched antenna is also discussed in this article. © 2012 Wiley Periodicals, Inc.

Optimal Work Pattern for Construction Workers in Hot Weather: A Case Study in Hong Kong

AbstractHaving established a Monte Carlo simulation-based algorithm to optimize work–rest schedule in a hot and humid environment, this paper attempts to develop the algorithm and identify an optimal work pattern, which may maximize the direct-work rates and minimize the health hazard due to heat stress to the workers concerned. Traditionally, construction workers in Hong Kong start work at 8:00 a.m. and finish work at 6:00 p.m. , having one hour lunch break between 12:00 p.m. and 1:00 p.m. , and an additional break of 30 min at 3:15 p.m. Construction workers can beat the heat by starting earlier to avoid some extreme conditions, which may occur at certain times of a day. By maintaining the current practice of 9-h working duration for a day, 21 additional work patterns with different start and finish times were proposed and evaluated by the developed optimization algorithm. An optimized schedule (direct-work rate of 87.8%) of working from 7:30 a.m. to 12:00 p.m. with a 20 min break at 9:40 a.m., having lunc.
Victims and survivors in fatal residential building fires

Of the 150 residential fire fatalities investigated by the State Coroner, Victoria, from mid-1990 to 1995, 132 resulted from 94 fires where the cause was either not deliberate or remained undetermined. Personal and behavioural characteristics of victims and survivors of these fires are examined. The 18 deaths from 15 intentional fires are described separately. Most victims evidenced known risk characteristics, such as being very old or very young, being asleep or being affected by alcohol. Victims under 5 years and over 65 were more likely to be awake and involved with the fire start. Three quarters of those asleep and half of those awake did not move from their original location - the latter were all in direct contact with the flames. In 14 of the 22 single fatality fires with survivors the victims were closer to the fire source. Survivors with risk characteristics and those who were close to the fire were likely to sustain injuries. Sample size is too small to indicate outcome differences between survivors with and without risk characteristics. Identifying individual factors that influence fire starts and outcomes for both victims and survivors is important for modelling human response as well as for targeting safety education.
Using MCDA to enable individual preference-based matchmaking in the sustainable mobility domain

This work provides a foundation to make heterogeneous alternatives for mobility (transportation modes) comparable in the context of sustainability and providing possibilities to also compare them in other contexts such as costs or flexibility. The key to a successful comparison of such transportation modes is stated as the selection of semantically suitable key performance indicators (KPI) and a reasonable decision analysis method, which will be covered throughout this work. A set of KPIs is selected by considering various existing indicators, like indicators for measuring resource consumption or air pollution. This work provides a method for comparing the relative sustainability or any other desired dimension, given the requirement that a suitable set of KPIs is selected, of multiple modes of personal transportation by using key performance indicators and the multi-criteria decision analysis method PROMETHEE II. In addition to the introduced objective decision support, the authors also provide a way to enable subjective decision support by taking the preference-based model of an individual decision-maker into account. A method to enable individual preference based matchmaking is introduced to provide the mathematical foundation for mapping each individual to their subjectively optimal transportation mode. Some possible practical use cases which are able to create real world added value by automated appliance of the introduced models are given by the authors as well.
Part Data Mining for Information Re-Use in a PLM Context

Difficulty in locating existing information in order to reuse it constitutes a major challenge to productivity. The use of PLM systems (Product Lifecycle Management) aims in particular to reduce the time and cost of developing a product by facilitating the re-use of existing parts or related information (process plans, tools, FEM, estimates, etc.). When information is alphanumerical, using search engines, such as those made popular on the internet, is efficient. However, a significant portion of information used in engineering rests within CAD (Computer Aided Design) models, making such search tools irrelevant. To aid in the re-use of information, two problems must be resolved: it is first necessary to be able to locate similar parts in the electronic database of the company, and then be able to systematically identify their differences. This article presents some of the results from our work on part, product and process data mining (P3 DM). It focuses on tools developed to search similar 3D geometric models and to identify their differences. The PartFinder application locates similar parts by comparing signatures extracted from their solid representations. The 3DComparator aims to identify the differences in terms of Form and Fit between the identified parts. In both cases, the recommended approach is independent of the CAD system, and can also deal with parts represented by IGES or STEP files. Moreover, the approach does not require that the parts occupy the same position and have the same orientation in space. These two points, CAD and position independence, are the main benefits of our approach compared to other existing applications. Lastly, if the comparison takes place between two evolutions of the same geometrical representation of a part, a third tool allows the comparison of the specification trees. The SpecComparator is also presented briefly. An example based on industrial data illustrates the benefit that could be generated.Copyright © 2007 by ASME
Research about the Influence of Clothing Store Designs and Displays on the Consumer Purchase Decision Based on the Data Analysis

Along with the increasing development of clothing market and our fashion industry, more and more clothing stores lay great emphasize on the designs and displays in their clothing store.

Reconfigurable microstrip antenna with polarisation diversity and frequency agility

A circularly-polarised (CP) microstrip antenna with polarisation and frequency diversities is presented. The antenna has a square radiating patch and is excited through the coupling of a cross-slot with unequal lengths. Two diodes are used to reconfigure the radiating patch, and by controlling the states of the diodes, the polarisation sense of the antenna can be switched between left-hand and right-hand circular polarisation. Moreover, the two CP modes are operated at different frequencies. An antenna prototype is implemented and the obtained results are shown.
Investigation into the performance of an adaptive array in cellular environment

This paper presents results which provide insight into the interference reduction capabilities of the adaptive linear array. It is shown that there is an improvement in SIR as N (number of linear array antenna elements) increases. The range of angles over which the most significant improvement occurs is limited to about /spl plusmn/60/spl deg/. This occurs when 12 antenna elements are used. Increasing N further results in diminishing returns. This suggests that in order to extend the angular range of improvement, a conformal (curved) array such as a cylindrical array covering a larger angular view, would be more beneficial. The findings indicate the need and importance of investigating design strategies and technologies for conformal base station antenna systems and associated adaptive algorithms.
Centralized call admission control and load balancing for voice over IP

IP networks are traditionally designed to support a best- effort service, with no guarantees on the reliable and timely delivery of packets. With the migration of real-time applications such as voice onto IP-based platforms, the existing IP network capabilities become inadequate to provide the quality-of-service (QoS) levels that the end- users are accustomed to. While new protocols such as DiffServ and MPLS allow some amount of traffic prioritization, guaranteed QoS requires call admission control. This paper reviews several possible implementations and shows simulation results for one promising method that makes efficient use of the network and is scalable to large networks.
Development of Industrial Load Control Algorithm for Factory Energy Management System (F-EMS) under Real Time Pricing Environment

- In real-time electricity price environment, the energy management system can provide the significant advantage to the residential, commercial and industrial customers since it can reduce the electricity charge by controlling the load operation effectively in response to time-varying price. However, the earlier studies for load management mainly focus on the residential and commercial customers except for the industrial customers because most of load operations in industrial sector are intimately related with production schedule. So, it is possible that the inappropriate control of loads in industrial sector causes huge economic loss. In this paper, therefore, we propose load control algorithm for factory energy management system(F-EMS) to achieve not only minimizing the electricity charges but also maintaining production efficiency by considering characteristics of load operation and production schedule. Considering characteristics of load operation and production schedule, the proposed load control algorithm can reflect the various characteristics of specific industrial customer and control their loads within the range that the production efficiency is maintained. Simulation results show that the proposed load control algorithm for F-EMS leads to significant reduction in the electricity charges and peak power in industrial sector.
An investigation into issues related to the latest version of iso 9000

Abstract This research studies the emergence of the latest version of ISO 9000, ISO 9001:2000, which takes a process-based approach to the implementation of quality management systems. The new version has abandoned the structure of 20 sections and now has five comprehensive sections covering all the previous requirements, with some modifications and the introduction of new requirements. This version has introduced a process-based approach that considers the quality management system as a single large process consisting of many smaller processes. The paper focuses on the implementation of ISO 9001:2000 through an empirical study on Canadian firms. Results show that, whether external or internal reasons provided the impetus for registration, Canadian companies registered under the new ISO standard generally face the same degree of difficulty in implementation. However, internally driven companies have less difficulty for certain items. Externally driven companies perceived a higher degree of benefits as compared with internally driven companies.
A circuital formulation for direct electrical resistive tomography problems

Purpose – Electrical resistive tomography (ERT) is a non‐destructive testing technique based upon the reconstruction of the electrical conductivity profile inside a body from measurement made on its boundary. In the literature about the inverse problems the ERT is considered still challenging being both non‐linear, ill‐posed and very limited in resolution. Purpose of the paper is to assess the performances of an approach exploiting the circuital behaviour of a particular class of problems, highlighting its advantages in terms of simplicity and reduction of the computer burden.Design/methodology/approach – In this paper, an electrical property of a particular class of problems is pointed out; the same property is used to formulate in terms of a circuital model the ERT problem. The proposed methodology consists basically of combining properly simplified data previously evaluated and collected. The overall procedure is presented with reference to an underground structure diagnostics problem.Findings – The ef.
Using measurements and decision tree processing for response-based discrete-event control

Synchronized phasor measurements can be transmitted in real-time to a central location for further processing. The use of synchronized phasor measurements for special protection systems is an emerging area of research. One of the main research challenges is to synthesize the output of multiple phasor measurement units (PMUs) into discrete control actions in real time. This paper describes the development of decision trees (DTs) for out-of-step relaying using local measurements, and for HVDC fast power changes using 12 sets of synchronized phasor measurements per second from 14 PMU locations. The DTs are trained automatically using time-domain simulation data. On-line transient security assessment tools could potentially enable adaptive control by periodically generating new training data.
Strength and Ductility of Confined Concrete

An analytical model is proposed to construct a stress‐strain relationship for confined concrete. The model consists of a parabolic ascending branch, followed by a linear descending segment. It is based on calculation of lateral confinement pressure generated by circular and rectilinear reinforcement, and the resulting improvements in strength and ductility of confined concrete. A large volume of test data, including poorly confined and well‐confined concrete was evaluated to establish the parameters of the analytical model. Confined concrete strength and corresponding strain are expressed in terms of equivalent uniform confinement pressure provided by the reinforcement cage. The equivalent uniform pressure is obtained from average lateral pressure computed from sectional and material properties. Confinement by a combination of different types of lateral reinforcement is evaluated through superposition of individual confinement effects. The descending branch is constructed by defining the strain correspond.
Bandwidth Enhancement using Capacitive Coupling and Stubs in a Printed Wide Slot Antenna

A novel design of a dual band antenna, consisting of U-L shaped structure with wide slot in the ground plane is presented. To improve the bandwidth, capacitive coupling and stubs are introduced in the radiating element. Further to improve the bandwidth, a wide slot in the ground plane is employed. The proposed antenna is printed on 1.6 mm thick FR4 substrate which has a relative permittivity of 4.4 and a loss tangent of 0.008. The radiating element size is 20 X 18 mm. The measured impedance bandwidth for the first band is 3.7 4.2 GHz (12.66%) and second band is 5.3 6.9 GHz (26.23%) at 5.6 GHz. The peak gain is around 4 dBi at 5.6 GHz.
